Pat ient outcomes associated wit h inguinal hernia repairs are significantly better than those associated with incisional hernia repairs. Avoidance of excessive fluid administ rat ion can improve the fascial clo- sure rat es for pat ient s following damage-cont rol laparot omies. Enteral- atmospheric fistula is a known complication associated with open abdomens. H ost comorbidit ies have not been ident ified for pat ient s at risk for having open abdomens. The patient described here is a 43-year-old man with diabetes and a prior failed ventral hernia repair that was associated with wound infec- tion and prosthetic mesh infection. This patient falls into grade 4 with ver y h igh r isk fo r wo u n d co m p licat io n s. Based o n this gr ad in g, the m o st appropriate choice listed is repair by component separat ion wit h biologic material reinforcement. The recommendation of no repair is also possible based on his high-risk status, but this is less desirable for a reasonably young individual. The tensile strength will continue to increase thereafter, but it never returns to the preinjury level. Using sutures shorter than this ratio may result in excessive tension on the suture or inadequate tissue incorporation in the fascia closure.

Best therapy: O perative exploration of the area to evaluate hernia, reduce the hernia sac contents, and repair the femoral hernia. Learn the pros and cons of hernia repairs, and the outcomes associated with the different approaches to hernia repairs. Co n s i d e r a t i o n s This patient presents with the sudden onset of pain and a mass in his right infra- inguinal area. The different ial diagnosis of groin pain and/ or mass includes ingui- nal hernia, femoral hernia, muscle strain, and adenopathy. This patient provides a history of being well until the sudden onset of pain during his tennis match. While it is not uncommon for many individuals t o believe that the sudden development of pain or mass in the groin is the classic present ation of hernias, the story described by this individual is actually very atypical for hernia presentation. Inguinal her- nia patients will often describe intermittent groin discomfort or “heaviness” that is more prominent wit h act ivit y and aft er st anding for prolonged periods of t ime. The mass that is identified in his right infra-inguinal area along with his descrip- tion of the events suggests that he has an acutely incarcerated right femoral hernia. Becau se a femor al h er n ia is an u n u su al h er n ia, an d this pat ien t ’s st or y is n ot en t ir ely st raight forward, imaging should be performed t o confirm t he diagnosis. O n ce the diagnosis is confirmed, we should proceed with expeditious exploration and repair of the hernia. The repair can be approached using an open incision placed above the inguinal ligament t hat allows the surgeon t o go t hrough t he inguinal floor t o id en t ify the fem or al can al an d ad d r ess the cont ent s in the in car cer at ed hernia. Once the hernia is reduced, a McVay-type repair (Cooper’s ligament repair) can be car r ied out wit h placement of pr ost h et ic mesh. In men, the hernia sacs follow the sper- matic cord and may descend into the scrotum, whereas the indirect inguinal hernia in women may present as labial swelling. The subtle difference between femoral hernia and inguinal hernia is that the femoral hernia is located below the inguinal ligament. Care should be t aken to verify the location of the inguinal ligament dur- ing t he examinat ion of pat ient s wit h hernias in t hat region of t he body. Umbilical hernias can also be acquired hernias, where subclinical defect s increase in size due t o increased int ra- abdominal pressures (eg, pregnancy, ascit es, or excess weight gain). What is unique about this type of hernia is that it may or may not be associated with intestinal obstruction, and that this t ype of hernia is often smaller and can be more difficult to diagnose. The area of incarcerated intest ine can develop ischemia and necrosis when t he process goes undiagnosed. This hernia occurs most commonly in women, part icularly mult iparous women wit h h ist ory of recent weight loss. A mass can be p alpable in the med ial t h igh, par t icu lar ly wit h h ip flexed, ext er n ally r ot at ed, and abducted. The indirect hernia sac in this t ype of hernia will cont ain t he att ach ment of t he int est ines. H igh-ligat ion of the sac without clearly identifying a hernia as a sliding hernia can cause ischemic injury t o t he int est ine wit h in t he sac. Incarceration involves the trapping of the abdominal content wit hin t he hernia sac (failure for t he content s to spont aneously reduce). Stran- gulation occurs when the blood supply to the trapped intra-abdominal contents becomes compromised, leading to ischemia, necrosis, and ultimately perforation. Intestinal obstruction can occur in association with either incarcerated or strangu- lat ed h ern ias. Abdominal wall defect s that develop following abdominal operat ions not related to hernia repairs are referred to as incisional hernias and are addressed elsewhere in t his t ext. An a t o m y Knowledge of the regional anatomy is essential for the diagnosis and repair of hernias. In the groin region, the inguinal ligament separates inguinal hernias from femoral h ern ias. In guin al h ern ias are fur t h er divided int o direct an d in direct h er- nias based on the relationship of the defects to the inferior epigastric vessels. The Hesselbach’s triangle, is defined by the edge of the rectus muscle medially, the inguinal ligament inferolaterally, and inferior epigastric vessels superiolaterally, and is the site of direct hernia occurrence. An in d ir ect in gu in al h er n ia or igin at es lat er al t o H es- selbach’s triangle. D irect inguinal hernias develop initially as tears in the abdominal wall within H esselbach’s t riangle, and this area is sometimes referred to by some surgeons as t he “inguinal floor.
Clinical Manifestations Symptoms result primarily from anticholinergic and cardiotoxic actions purchase tadalafil discount erectile dysfunction symptoms. The combination of cholinergic blockade and direct cardiotoxicity can produce dysrhythmias buy generic tadalafil 2.5mg online erectile dysfunction pills, including tachycardia, intraventricular blocks, complete atrioventricular block, ventricular tachycardia, and ventricular fibrillation. Responses to peripheral muscarinic blockade include hyperthermia, flushing, dry mouth, and dilation of the pupils. Treatment Absorption of ingested drug can be reduced with gastric lavage followed by administration of activated charcoal within 2 hours of ingestion. Intravenous administration of sodium bicarbonate is recommended to control dysrhythmias caused by cardiac toxicity. Dysrhythmias should not be treated with procainamide or quinidine because these drugs cause cardiac depression. High doses are undesirable in that they pose an increased risk for adverse reactions. They are unnecessary in that onset of therapeutic effects is delayed regardless of dosage, and hence aggressive initial dosing offers no benefit. However, if there is no observable response, plasma drug levels can be used as a guide. If bedtime dosing causes residual sedation in the morning, dosing earlier in the evening can help. Although once-a-day dosing is generally desirable, not all patients can use this schedule. Older adults, for example, can be especially sensitive to the cardiotoxic actions of the tricyclics. As a result, if the entire daily dose were taken at one time, effects on the heart might be intolerable. For example, if the patient is experiencing insomnia, a drug with prominent sedative properties (e. Older-adult patients with glaucoma or constipation and males with benign prostatic hypertrophy can be especially sensitive to anticholinergic effects. The greatest concern is hypertensive crisis, which can be triggered by eating foods rich in tyramine. Inactivation helps maintain an appropriate concentration of transmitter within the terminal. These secondary events, which have not been identified, are ultimately responsible for the beneficial response to treatment. In contrast, recovery from reversible inhibition is more rapid, occurring in 3 to 5 days. As with other antidepressants, beneficial effects do not reach their peak for several weeks. Excessive stimulation can produce anxiety, insomnia, agitation, hypomania, and even mania. Patients should be informed about signs of hypotension (dizziness, lightheadedness) and advised to sit or lie down if these occur. Also, they should be informed that hypotension can be minimized by moving slowly when assuming an erect posture. Hypertensive crisis is characterized by severe headache, tachycardia, hypertension, nausea, vomiting, confusion, and profuse sweating—possibly leading to stroke and death. P a t i e n t E d u c a t i o n Hypertensive Crisis Patients should be informed about the symptoms of hypertensive crisis (headache, tachycardia, palpitations, nausea, vomiting, sweating) and instructed to seek immediate medical attention if these develop. Accordingly, patients should be instructed to avoid all medications— prescription drugs and over-the-counter drugs—that have not been specifically approved by the prescriber. Patients should be instructed to avoid all sympathomimetic drugs, including ephedrine, methylphenidate, amphetamines, and cocaine. Sympathomimetic agents may be present in cold remedies, nasal decongestants, and asthma medications; all of these should be avoided unless approved by the prescriber. These drugs must be used with caution because their effects will be more intense and prolonged. However, although potentially dangerous, the combination can benefit certain patients. Clinical trials have shown that restricting dietary tyramine is unnecessary with low-dose selegiline (24 mg/24 hours). However, owing to a lack of data, tyramine restriction is recommended at higher selegiline doses. Two drugs—carbamazepine [Tegretol] and oxcarbazepine [Trileptal]—can significantly raise levels of selegiline. The most common adverse reaction is localized rash, which develops in about one third of patients. Atypical Antidepressants Bupropion Actions and Uses Bupropion [Wellbutrin, Budeprion, Aplenzin] is a unique antidepressant similar in structure to amphetamine. In addition to its use in depression, bupropion, marketed as Zyban and Buproban, is approved as an aid to quit smoking (see Chapter 32). Unlabeled uses include relief of neuropathic pain, treatment of depressive episodes in bipolar disorder, and management of attention-deficit/hyperactivity disorder. With the immediate-release tablets, plasma levels peak about 2 hours after dosing. Bioavailability is low: in animals, only 5% to 20% of each dose reaches the systemic circulation. In addition, bupropion carries a small risk for causing psychotic symptoms, including hallucinations and delusions. Like other antidepressants, bupropion may increase the risk for suicide in children, adolescents, and young adults. In contrast to many other antidepressants, bupropion does not cause adverse sexual effects. Mirtazapine Mirtazapine [Remeron] is the first representative of a new class of antidepressants. The mechanism is blockade of presynaptic alpha -adrenergic receptors that2 serve to inhibit release. Mirtazapine blocks histamine receptors and thus promotes sedation and weight gain. Mirtazapine is well absorbed after oral dosing and reaches peak plasma levels in 2 hours. The drug undergoes extensive hepatic metabolism followed by excretion in the urine (75%) and feces (25%). Reversible agranulocytosis was reported in early trials but was not confirmed in later clinical experience. Blockade of muscarinic receptors is moderate, and hence anticholinergic effects are mild. Other Atypical Antidepressants Nefazodone Nefazodone is a novel drug indicated only for depression. The most common side effects are sedation, headache, somnolence, dry mouth, nausea, constipation, dizziness, blurred vision, and other visual disturbances.
Long-term metronidazole treat- ment is poorly tolerated because of its associated nausea order tadalafil amex xenadrine erectile dysfunction, metallic taste tadalafil 20 mg with visa impotence reasons and treatment, disulfiram- like react ions, and periph eral neuropat h ies. Moderate to severe disease refractory to antimicrobials and inflammatory medications are typically treated with corticosteroids. Steroids are most commonly applied for disease flar e-u p s an d t h en t ap er ed or d iscon t in u ed t o avoid t h eir lon g-t er m major sid e effect s. Budesonide is a newer cort icost eroid agent t hat is being ut ilized as it is met abolized more rapidly t han prednisone and is associat ed wit h fewer side effect s. In patients with moderate to severe disease in remission after a course of cor- ticosteroids treatment, immunomodulators are sometimes prescribed for main- tenance therapy. T h e major sid e effect s of t h ese medica- tions are bone marrow suppression, nausea, fever, rash, hepat itis, and pancreatit is. Methotrexate is also used in the treatment of active disease, and this medication can cau se n au sea, h eadach e, st omat it is, bon e m ar r ow suppr ession, h epat it is, an d pneumonitis. Infliximab is h igh ly effect ive in the t r eat m en t of p at ient s wh ose d isease is r efr ac- tory to all other treatments. Studies suggest that it may delay or obviate opera- tive treatments for some patients with severe disease. It can also be used as the fir st -lin e t r eat m en t of patient s wit h sever e p er ian al fist u lizin g d iseases. T h e major side effect s and complicat ions associat ed wit h t his t reat ment include opportunist ic infect ions and B-cell lymphoma development. Recently, there has been some debate within the gastroenterology circle regard- ing t he opt imal st rat egy in t he medical management of Croh n disease pat ient s. Some practitioners believe that the “top-down” approach that initiates treatments wit h t he most potent medicat ion, and t ransit ioning to t he less potent medicat ions aft er the pat ient s response is a bet t er approach t han t he t radit ional “t reat ment escalat ion” approach. Su r g ica l Ma n a g e m e n t The two most common reasons that surgeons are consulted for Crohn disease patients are medical treatment failures (unable to maintain employment, school- ing, diet ary int ake, or maint ain sufficient body weight s due t o failure t o t hrive or medical refractory disease), or when the medical treatment side effects affect qual- it y of life. At ot h er t imes, surgeons are asked t o h elp t reat disease complicat ions including obst ruct ion, fistulizat ion, and neoplast ic t ransformat ion. Adenocarci- noma of the small bowel is an unusual disease in the general population. H owever, the disease incidence is approximately 100 times greater in Crohn disease patients. Surgical treatment options include intestinal resection, strictureplasty, and intesti- nal bypass. Endoscopic dilat ation of intestinal st rictures is a new technique that is being applied for some patients with Crohn disease related intestinal obst ructions. O n e of the p ot en - tial long-term complications associated with reoperative treatments for patients wit h Crohn disease is the loss of bowel lengt h to maint ain normal nut rit ional func- tions (short bowel syndrome); this complication is reported in less than 1% of patients with Crohn disease. Po st o p e ra t ive St ra t e g ie s The initiation of medical therapies early during the postoperative periods has been suggested to reduce disease recurrences. Because these medications can affect wound healing and increase surgical complicat ions, most pract it ioners rec- ommend a slight delay before initiation of pharmacologic treatments after a sur- gical op er at ion ( 10 days). T h e d ecision r egar d in g t im in g an d the t yp es of med ical treatments should be determined by a multidisciplinary team. For smokers, smoking ces- sat ion has been demonst rated to be associated wit h up to a 50% reduct ion in disease recurrences.

M edical refract or y disease is the most common in dicat ion for sur ger y in Crohn disease patients. The role of surgery is to improve the patient’s quality of life, and surgery has no impact on the disease itself. Surgery is indicated when medical therapy is not working or if medical treatment side effects are compromising the patients’quality of life significantly.

Women with retained products of con- ception (P O Cs) generally have uterine cramping and bleeding generic tadalafil 2.5mg fast delivery impotence l-arginine. If suspecting infec- tion (endometritis) purchase cheapest tadalafil erectile dysfunction melanoma, broad-spectrum antibiotics are indicated. Endometritis is sus- pected with uterine fundal tenderness, fever, and foul-smelling lochia. This includes oxytocin given immedi- ately upon delivery of the infant, late cord clamping, and gentle cord traction with uterine countertraction with a well-contracted uterus. Several randomized trials foun d a 25% t o 50% decrease in the in ciden ce of P P H. Alt h ough ret ain ed placent a is a t heoret ical risk wit h early oxyt ocin administ rat ion, studies have not found t his complicat ion. After being at 6-cm dilation for 3 hours despite adequate uter- ine cont ract ions as judged by 240 Mont evideo unit s, she underwent a cesarean delivery. Upon delivery of t he placent a, profuse bleeding was not ed from t he uterus, reaching 1500 mL. The obstetrician noted significant blood loss from the vagina, totaling approxi- mately 700 mL. W hich of the following is the most common etiology for the bleeding in this patient? W hich of the fol- lowing is most appropriat e t o ach ieve the t h erapeut ic goals? Ut er in e at ony is the most common cau se of P P H, even aft er cesar ean deliv- ery. W it h a prolonged labor, such as wit h arrest of act ive phase, a pat ient is at risk for uterine atony. Certainly, lacerations or injury to uterine vessels are potential issues and should be visible on examination. If these measures are unsuccessful, surgical 2 management of uterine atony includes ligation of blood supply to the uterus to decrease the pulse pressure (suture ligation of the ascending branch of the uterine artery or the utero-ovarian ligament or internal iliac artery) or place- ment of compression stitches (B-lynch stitch) that try to compress the uterus wit h external suture “nett ing. This is most likely arising from a cervical laceration, commonly laterally into or adjacent to the arterial supply of the cervix. If the fundus is firm and the uterus well contracted, the next step should be to assess for a genital tract lac- erat ion. Inspect ion for whet her t he bleeding is coming supracervical (ut erus) ver su s cer vical o r lower in the gen it al t r act is cr it ical. S u p r acer vical b leed in g speaks for coagulopat hy, ret ained P O C, or at ypical ut erine at ony. O ften, if the patient is in a regular labor and delivery room, moving the patient to the oper- ating room with adequate light ing and anesthesia can be helpful. At times, a genit al tract lacerat ion may extend high into the vaginal fornix; careful assessment of the full extent of the laceration and judicious surgical repair is warranted. Ligation of utero-ovarian ligaments can be per- formed in addit ion t o ligat ion of ut erine art eries, wh ich can diminish furt h er blood flow to the uterus. A cervical cerclage is not a t reat ment opt ion for h em- orrhage; instead, it is a procedure performed in order to prevent preterm labor and delivery in a pregnant woman with cervical insufficiency. Bleedin g from mu lt iple ven ipun ct ure sit es t oget h er wit h abr upt ion suggest s a coagulopathy. T his is a systemic response, so no type of localized treatment (such as hypogastric artery ligation or utero-ovarian ligament ligation) will fix the problem. A patient with disseminated intravascular coagulation can pres- ent wit h a simult aneously occurring t h rombot ic and bleeding problems, wh ich makes it difficult to choose a treatment option. The most common cause of late postpartum hemorrhage is subinvolution of the uterus, in which the placent al implant ation site does not decrease in size as expected; t hus, when t he eschar overlying t he placent al site falls off (7– 10 days after delivery), there is more bleeding than expected.

Next diagnostic step: Basic ob st et r ic u lt r asou n d exam in at ion t o assess for d at es and mult iple gest at ions. Understand that the most common causes of abnormal serum screening are wrong dates and multiple gest ations. Know that an elevated maternal serum α -fetoprotein level may be associated with an open neural tube defect. Be aware of the large number of noninvasive and invasive tests for fetal anoma- lies and aneuploidy. Co n s i d e r a t i o n s This patient is at 16 weeks’ gestation by a fairly certain last menstrual period, which is consistent with the clinical examination. The gestational age window of 16 to 20 weeks is the appropriate time to screen with serum testing. At 16 weeks’gestation, the fun- dus is usually midway between the symphysis pubis and the umbilicus. At 20 weeks’ gestation, the fundal height is generally at the level of the umbilicus. Although the triple screen may be offered to women over t he age of 35 years, or advanced maternal age, gen et ic am n iocent esis p r ovid es m or e d iagn ost ic in for m at ion. It passes into the maternal cir cu lat ion by d iffu sion t h r ou gh the ch or ioam n iot ic membr an es. H uman ch or ion ic gon ad ot r opin, h owever, is elevat ed in t h ese fet u ses. By combin in g t h ese serum chemicals into a mult iple marker screening test, approximately 60% of all Down syndrome pregnancies can be identified. Different variations of the multiple marker test exist, such as one t hat adds inh ibin A as a fourt h analyt e t o furt her improve det ect ion rates. The nuchal translucency is an echolucent area seen at the back of the fet al neck. W hen performed between 10 and 13 weeks’ gestation, 85% of Down syndrome may be ident ified and 90% of t risomy 18 may be ident ified. Furt hermore, first -t rimest er screening may be combined with second-t rimester screening to improve t he detec- tion rate of Down syndrome to 90%. The first step in the management of an abnormal triple screen is a basic ultra- sound to determine t he correct gest at ional age, to ident ify t he possibilit y of mul- tiple gest ation, and to exclude fet al demise. If the risk of t risomy or neural tube defect s is st ill increased after a basic sonogram, amniocentesis or t arget ed ult rasound is offered. A targeted examination can correctly identify fetuses with neural tube defects by direct visualization of the fetal head and spine. Furthermore, ultrasound may also detect those fetuses suspicious for having Down syndrome by identification of a thickened nuchal fold, shortened femur length, or echogenic bowel. Fet al karyot ype is also obt ained t h rough amniocent esis, wh ich will ident ify fet al aneuploidy, such as the t risomies. The identification of a fetus affected by a neural tube defect or a chromosomal abnormalit y can be an et h ical and moral dilemma for the parent s, whose previous hopes and dreams for having a “normal” child are now extinguished. The parents should not be forced int o any decision, but should be provided informat ion in an unbiased fashion.

After a 4-hour first stage of labor and a 2-hour second st age of labor, the head delivers but the shoulders do not easily deliver. Next step in management: McRobert s maneuver (hyperflexion of t he mat ernal hips onto the maternal abdomen and/ or suprapubic pressure). Li kely co mplicat io n: A likely maternal complication is postpartum hemor- rhage; a common neonatal complication is a brachial plexus injury such as an Erb palsy. Maternal condition: Gestational diabetes, which increases the fetal weight on the shoulders and abdomen. Understand that shoulder dystocia is an obstetric emergency, and be familiar with the init ial maneuvers used to manage this condition. Considerations The patient is multiparous and obese, both of which are risk factors although not the strongest risk factors, for shoulder dystocia. The prenatal risk factors in order of significance are (1) prior shoulder dystocia, (2) fet al macrosomia, and (3) maternal gestational diabetes. The patient is post-term at 42 weeks, which increases the likelihood of fet al macrosomia. T h e pat ient ’s prolonged secon d st age of labor (upper limit s for a multiparous patient is 1 hour without and 2 hours with epidural analgesia) may be a nonspecific indicator of impending shoulder dyst ocia. N evert heless, t he diagnosis is st raight forward, in t hat t he fet al shoulders are described as not easily delivering. Shoulder dystocia should be suspected with prior history of shoulder dystocia, fetal macrosomia, gestational diabetes, excessive weigh t gain (> 35 lbs) in pregnan cy, maternal obesity, and prolonged second stage of labor. With gestational diabe- tes, the elevated fetal insulin levels are associated with increased weight centrally (shoulders and abdomen). H owever, it must be noted that almost one-half of all cases occu r in babies weigh in g less t h an 4000 g, an d sh ou ld er dyst ocia is fr equ ent ly unsuspected. Significant fetal hypoxia may occur with undue delay from the deliv- ery of t he head t o t he body. Moreover, excessive t ract ion on t he fet al head may lead to a brachial plexus injury to the baby. It should be recognized that brachial plexus injury can occur wit h vaginal delivery not associated wit h shoulder dystocia, or even wit h cesarean delivery. Shoulder dyst ocia is not resolved wit h more t ract ion, but by maneuvers to relieve the impaction of the anterior shoulder (Table 4– 1). The diagnosis is suspected when external rotation of the fetal head is difficult, and t he fet al head may ret ract back toward the maternal int roitus, t he “turtle sign. The first actions of the fetus are nonmanipulative, such as the McRoberts maneuver and suprapubic pressure. Fortunately, the majority of shoulder dystocia cases are r elieved wit h t h ese n on man ipu lat ive act ion s. Fu n dal pr essu r e sh ou ld be avoided when shoulder dystocia is diagnosed because of the increased associated neonatal injury. Other maneuvers include the Wood’s corkscrew (progressively rotating the posterior shoulder in 180° in a corkscrew fashion), delivery of the pos- terior arm, and the Z avanelli maneuver (cephalic replacement with immediate cesar- ean section). Maternal complications of shoulder dystocia include both postpartum hemorrhage and vaginal/ perineal lacerations. Fetal complications include brachial plexus injuries, clavicle fractures, hypoxic-ischemic encephalopathy, and even death. One area of controversy is the practice of cesarean delivery in certain circum- st ances in an at t empt t o avoid shoulder dyst ocia; indicat ions include macrosomia diagnosed on ultrasound, particularly with maternal gestational diabetes. Operative vaginal delivery, such as vacuum- or forceps-assist ed deliveries in t he face of possible fet al macroso- mia, may possibly increase the risk of shoulder dystocia. Delivery of the fet al head occurs, but the fet al shoulders do not deliver with the normal traction. D ecr eases the fet al b o n y d iam et er fr o m sh o u ld er – sh o u ld er t o sh o u ld er – axilla C. Gestational diabetes is a risk factor because the fetal shoulders and abdo- men are disproportionately bigger than the head, therefore the head may pass through with no problems, yet it is quite difficult to deliver the anterior shoul- der since it is lodged behind the maternal symphysis pubis. The McRoberts maneuver and application of suprapubic pressure are two techniques that attempt to relieve the impact ion of the anterior shoulder. Unlike gest at ional diabetes, the complication with hydrocephalus is that the fetal head is greater than the body. The head itself may have a difficult time passing through the pelvis, but if it does pass, the shoulders would have no problem passing through since t heir widt h would be smaller than t he widt h of t he fet al head. The pre- mature fetus typically has a well-proportioned body, but is overall smaller in size than t he average-sized baby. N o part of a premature fetus’ body should typically get impacted anywhere along the birth canal. With precipitous labor, there is a decreased chance that a shoulder dystocia will occur, whereas a pro- longed second st age of labor sh ould raise suspicion that a dyst ocia is present. T h e M cRob er t s m an eu - ver o r su p r ap u b ic p r essu r e is gen er ally the fir st m a n eu ver u s ed. T h e M cR o b - ert s maneuver involves sharply flexing t he mat ernal t high s against t he mat ernal abdomen t o st raight en t he sacrum relat ive t o t he lumbar spine and rot at e t he symphysis pubis ant eriorly t oward t he mat ernal head. Applying suprapubic pressure, or pushing on the suprapubic region, relieves the fetal shoulder from being impacted behind the symphysis pubis. The internal podalic version is an obstet ric procedure in which t he fetus, t ypically in a t ransverse posit ion, is rotated inside the womb to where the feet or a foot is the presenting part dur- ing labor and delivery. This met hod would not be applicable in this situat ion because the fetus is presenting in the proper cephalic position. Fracturing of the fetal humerus is a complication that can occur with shoulder dystocia if one of the fetal arms is pulled or tugged on too forcefully. Attempting to deliver the anterior shoulder in the setting of shoulder dystocia can result in a brachial plexus injury involving the C5– C6 nerve roots. As a result, the baby could have weakness of the delt oid and infraspinat us muscles as well as the flexor muscles of the forearm (Erb palsy/ ”Waiter’s t ip”). An Er b palsy is the most common injur y of the n eon at e in a sh oulder dyst o- cia. T h e ar m is t ypically limp an d at it s side wit h the ar m int er n ally r ot at ed. Eighty percent of the time, brachial plexus injuries will improve with physical therapy.
Early decelerations are thought to be a result of increased vagal tone caused by compres sion of the fetal head and are not associated with fetal hypoxia or acidemia cheap tadalafil 10mg without prescription erectile dysfunction treatment in usa. A late deceleration is a gradual reduction in the fetal heart rate that starts at or afer the peak of a contraction and has a gradual return to the baseline effective 20 mg tadalafil impotence word meaning. Common among these are maternal hypotension, as is ofen seen with epidural anesthesia and uterine hyperstimulation caused by oxytocin administration. Conditions that impair placental circulation, including maternal hypertension, diabetes, prolonged pregnancy, and placental abruption, ofen con tribute to late decelerations. A vriable deceleration is an abrupt decrease in ftal heart rate, usually fllowed by an abrupt return to baseline that occurs variably in its timing, relative to a contraction. Variable decelerations are the most common types of decelerations seen during ftal heart monitoring and are considered to be due to umbilical cord compression during contractions. Variable decelerations, particularly when there is also the presence of normal variability and accelerations, are usually not associated with ftal hypoxemia. Current ftal monitoring equipment also allows fr contraction monitoring along with the ftal heart rate assessment. It allows fr evaluation of the presence and timing of contractions but does not measure the strength of the contractions. Con tractions that are inadequate in fequency or power may be augmented with an oxytocic agent. Intravenous oxytocin is the drug of choice, as it is efective, inex pensive, and most practitioners are fmiliar with its usage. Oxytocin has a short half-lif, which allows it to be given by continuous infsion and allows fr the rapid cessation of its activity when it is discontinued. Labor augmentation with oxytocin can cause uterine hyperstimulation, defned as the presence of six or more contrac tions in a 10-minute period that causes nonreassuring fetal heart rate abnormali ties (such as late decelerations). This would be managed by reduction in dose or discontinuation of the oxytocin, repositioning of the patient, and providing oxygen via fce mask to the mother. During labor, the fetal head descends through the birth canal and undergoes fur cardinal movements. During initial descent, the head undergoes Hexon, bring ing the ftal chin to the chest. As descent progresses, inteal rotaton occurs, caus ing the ftal occiput to move anteriorly toward the maternal symphysis pubis. Fur ther extension leads to the delivery of the head, which then restitutes via exteral rotaton to fce either to the maternal right or lef side. This corresponds with rota tion of the ftal body, aligning one shoulder anteriorly below the symphysis pubis and the other posterior toward the sacrum. Maternal pushing, along with gentle downward traction on the ftal head, will deliver the anterior shoulder, and upward traction similarly delivers the posterior shoulder. Occasionally, the anterior shoulder will not readily pass below the pubic symphysis. This is called a shoulder dystocia and is an obstetrical emergency, requiring a coordinated efrt by the entire medical team to reduce the dystocia. Maneuvers, including hyperflexion of the hips (McRoberts maneuver), suprapubic pressure, cutting an episiotomy, or rotation of the ftal body in the vaginal canal, are attempted and are usually successfl. Of deliveries in the United States, 20% or more are accomplished via cesarean delivery. The most common indications are a history of prior cesarean delivery, arrest oflabor or descent, ftal distress necessitating immediate delivery, and breech presentation. Operative vaginal delivery can be perfrmed using either frceps or vacuum assistance. These can only be used when the cervix is completely dilated, membranes are ruptured, the presenting part is the vertex of the scalp, and there is no disproportion between the size of the ftal head and maternal pelvis. Ifany of these conditions are not met and delivery must be accomplished urgently, a cesar ean delivery is indicated. Testing is done by swabbing the vagina, perineum, and anus with a sterile culture applicator. Alternatively, ampicillin could also be used, and this is ofen institution depen dent. If there is no true allergy but intolerance to penicillin, cefazolin should be used. For isolates susceptible to the above alternatives, clindamycin is appropriate; in cases of resistance, vancomycin should be used. Variable decelerations are caused by cord compression and late decelerations by uteroplacental insufciency. Rupture of membranes fr less than 18 hours does not preclude her fom receiving prophylaxis as she already has the indication of preterm labor that justifes beginning prophylaxis. The presence of accelerations on a fetal heart tracing is very reassuring and consistent with a fetal pH of greater than 7. Fetal heart rate tracings must be interpreted within the overall clinical sit uation. Reduction in variability shortly afer giving a narcotic pain medi cation may represent fetal sleep cycle; reduction in variability along with repetitive late decelerations may be an ominous sign of fetal distress. She was seen 1 week earlier in the emergency department fr abdominal pain and was diagnosed with nephrolithiasis. Ultimately, she was sent home with pain medications and given instructions to strain her urine fr stones and to fllow up with her primary care physician. She had several routine laboratory tests drawn in the emergency department, copies of which she brings with her. Upon your review of the laboratory values, you note the fllowing (normal values are in parenthesis): sodium 142 mEq/L (135-145); potassium 4. Upon questioning, you learn that she has had multiple episodes of"kidney stones" in the past 2 years. You send the stone to the laboratory fr analysis and order a repeat serum calcium level. The results show that the stone is made of calcium oxalate; the serum calcium is still elevated at 11. She had an ini tial serum calcium level that was elevated, as was the repeat serum calcium 1 week later. She takes no medications, and has a fmily history only signifcant fr hypertension. Many times, patients with hypercalcemia are asymptomatic and an elevated calcium level is fund unexpectedly on routine laboratory studies. The diagnostic workup is designed to distinguish parathyroid dys fnction fom other etiologies so that optimal treatment and management can be pursued.
Idiopathic relapsing pericarditis may be present in 20% cases of acute pericarditis buy tadalafil with visa erectile dysfunction quality of life. If pericarditis persists 6 to 12 months following acute attack purchase generic tadalafil canada erectile dysfunction drugs walmart, it is considered chronic. Presentation of a Case: (Supposing Both Knee and Ankle Joints) • Both the knee and ankle joints are swollen, skin is red and shiny, local temperature is raised and the joints are very tender. A: As follows: • I would like to examine the heart to see evidence of carditis (pericarditis, myocarditis and endocarditis). Features are: • Migrating (feeting), non-deforming polyarthritis involving the large joints (knee, ankle and elbow) and wrists with fever, may be continuous, high grade is the presenting feature in 75% cases. A: It is a multisystem disorder, occurs as a sequela to pharyngitis by Streptococcus b-haemolyticus group A. It is due to autoimmune reaction between the antigen (M protein) of Streptococcus hae- molyticus and cardiac myosin and sarcolemmal membrane protein (laminin). As a result, antibody is produced against streptococcal enzyme, causing infammation in the endocardium, myocardium and pericardium as well as joints and skin. A: It is a granulomatous nodule composed of central fbrinoid necrosis and multinucleated giant cells, surrounded by macrophage and T-lymphocytes. A: Commonly large joints, ankle, wrist, knee and elbow (usually does not involve small joints of the hands and feet, rarely involves hip joint). Following an attack of Streptococcus pharyngitis, there is usually a latent period of 1 to 3 weeks. Evidence of recent streptococcal infection • Positive throat culture for group A streptococcus. Diagnosis is made by two or more major criteria or one major and two or more minor criteria plus supportive evidence of streptococcal infection. Signs of pericarditis: • Pericardial rub (patient usually complains of chest pain). A: It is characterized by transient raised pink or red rash, blanches on pressure, with clear centre and round margin. It occurs in 10% of cases, found mostly on the trunks and proximal limbs (but not on face). A: These are small, frm and painless pea shaped nodules, felt over bony prominence and tendons or joints in extensor surface, present in 10 to 15% cases. Found in 1/3rd cases, common in children and adolescents, more in female of 5 to 15 years of age. Sedation (haloperidol) along with other treatment and prophylaxis of rheumatic fever should be given. Oral phenoxymethyl penicillin 250 mg 6 hourly for 10 days or single injection of benzathine penicillin 1. Treatment of complications like cardiac failure, valvular lesion, heart block, arrhythmia etc. To prevent recurrence: • Oral phenoxymethyl penicillin 250 mg 12 hourly or injection benzathine penicillin 1. Effusion in right knee in rheumatic fever Swelling of knee joint in rheumatic fever mebooksfree. Pulse: 88/min, normal volume, normal in rhythm, no radio-femoral or radio-radial delay. Q:What are the factors that alter the intensity of the murmur at left lower sternal border? A: It increases during standing and valsalva manoeuvre, decreases during squatting or sustained hand grip. A: Cardiomyopathies are a group of disease that primarily affect the heart muscle and are not due to congenital, acquired valvular, hypertension, coronary arterial or pericardial abnormalities. A: Hypertrophic cardiomyopathy is a disease of the heart muscle characterized by hypertrophy of cardiac muscle with malalignment of the cardiac fbres. In non-obstructive case: • Beta-blocker, rate limiting calcium channel blocker (e. In signifcant left ventricular outfow obstruction: • Dual chamber pacing may be needed. The patient usually tolerates pregnancy well, if not severely symptomatic prior to conception. Following precautions should be taken: • Prenatal counselling regarding risk of disease in offspring. After completing the clinical examination, one should present the case according to the examiner’s instruction. If you are asked to examine the back of chest only, tell the patient to keep both hands on the shoulder, i. Remember, common symptoms of any respiratory diseases are: • Cough with or without sputum production. The patient should lie fat, but if acutely ill or dyspnoeic, he/she can be examined in the position in which the patient feels comfortable. If you are asked to examine the respiratory system, the following important general examinations should be done: 1. While talking, hoarseness of voice (indicates laryngitis or recurrent laryngeal nerve palsy). Cachexic or emaciated (due to tuberculosis, bronchial carcinoma, lean and thin in emphysema), obesity (associated with sleep apnoea syndrome). In the face (look at the following points carefully): • Pink puffer (due to emphysema). In the hands (look at the following points carefully): • Nicotine staining in nails (may be associated with bronchial carcinoma). Heart (to see evidence of pulmonary hypertension, features of mitral stenosis, which causes pulmonary oedema, signs of chronic cor-pulmonale etc. Always examine both front and back of chest, both right and left side during each part of examination. Palpation: • Position of trachea (whether it is central, deviated to right or left). Percussion: • Percussion note (normal resonance, hyperresonance, stony dull or woody dull, impaired dullness). Area of liver dullness (normally in the right 6th rib or 5th intercostal space in mid-clavicular line. Auscultation: Turn the head of the patient to the left side and tell him, ‘Keep your mouth open, take deep breath in and out for me’. Breath sound (normal vesicular, vesicular with prolonged expiration or bronchial). If the vocal resonance is increased, always test for whispering pectoriloquy (usually it is present). Kussmaul’s breathing (air hunger): It is characterized by deep, sighing, rapid respiration at regular rate due to stimulation of respiratory centre. Ataxic breathing (Biot breathing): Characterized by irregular respiration in timing and depth. Cheyne–Stokes breathing: Cyclical variation in the depth of respiration characterized by gradual deepening of respiration till a maximum is attained, followed by gradual diminished respiration till a period of apnoea occurs (apnoea alternates with hyperpnoea).
