By R. Zuben. East Texas Baptist University.

Inform her next of kin cheap 100mg desyrel with amex, perform an appendectomy order 100 mg desyrel with visa, and aspirate the lesion to send for cytology C. Inform her next of kin, perform an appendectomy and unilateral salpingoophorectomy, await pathology D. Given this patient has a relatively large cystic lesion and is most likely done with childbearing, removing the affected tube and ovary is an appropriate first step. Ovarian Mass- Benign May be solid or cystic Functional process or neoplasia Size, age of patient, tumor characteristics factor in on necessity of surgical removal 90% tumors in women younger than 30 benign 80% benign in 30-50 yrs 50% malignant in pts over 50 Follicular cysts- failure of a developing follicle to develop or regress. This is not considered a sentinel event because it is not due to your medical error D. The patient probably only has 3 glands so the hyperparathyroidism was probably misdiagnosed as an adenoma and is most likely secondary to hyperplasia B. You should close at this point and repeat sestamibi postoperatively Answer 13 C. This tumor is most likely a benign esophageal leiomyoma and can be adequately treated with enucleation. Benign Tumors of Esophagus Benign tumors and cysts of the esophagus are uncommon Can be intramural or intraluminal Leiomyomas- 50% of benign tumors Usually solitary in lower 1/3 Dysphagia and pain most common sx Dx- barium swallow Biopsying may scar tissue planes, complicating removal Can be removed by simple enucleation Esophageal cysts Enteric or bronchogenic cysts Usually intramural in the middle or lower 1/3 Treat by enucleation Question 1 A 62 yo man presents with ischemic lesions in his right foot. Esophagectomy should be recommended Barretts & High Grade Dysplasia Esophagectomy is considered the standard Have 10% incidence of associated malignancy with high-grade dysplasia For non-high grade Barretts, endoscopic surveillance and treatment of reflux (surgical or medical) is appropriate Question 4 Which of the following is a contraindication for sentinel lymph node biopsy in breast cancer? This is likely an intraductal papilloma and there is a 50% chance of this being malignant B. Localization with major duct excision Is usually curative Intraductal Papilloma of Breast Most commonly present with bleeding/bloody nipple discharge. His final pathology reveled a focus of adenocarcinoma in the lamina propria of the gallbladder but no invasion into the muscularis. It is a difficult dissection so you decide to perform an intraoperative cholangiogram. It appears that you have inserted the catheter through the common bile duct itself. You note that he has wounds that are very slow to heal, a periorbital rash, and some darkening of his skin creases. His wounds have mostly been treated with debridement and topicals and he has been otherwise stable. He has recently developed a metabolic acidosis after you added a new topical to his wound care regimen. Most T3 supplements need to be held for at least 3 weeks prior to I-131 Preparation for I-131 scan Patient has to be hypothyroid for the scan Need to stop thyroid hormone before scan Synthroid/levothyroxine (T4) stop 6 weeks prior Cytomel/liothyronine (T3) stop 3 weeks prior Question 16 A 31 yo female who had a successful cadaveric renal transplant 6 months ago presents with rising creatnine. It is more common in renal recipients than in heart/lung recipients Answer 17 C. Type 1 Question 20 Which of the following types of collagen is likely low in Ehler-Danlos syndrome? Type 3 Question 21 About what concentration of microogranisms does it take to impede wound healing? It prevents production of thyroid hormone but not peripheral conversion of T3 to T4 C. It prevents production of thyroid hormone as well as peripheral conversion Answer 22 B is false. It prevents production of thyroid hormone as well as peripheral conversion of T3 to T4 Question 23 Which of the following patients with hyperthyroidism do not have a significant indication to perform thyroid resection? A 47 yo female with a large goiter that is beginning to cause compressive symptoms D. A 61 yo male that has been treated with methimazole for 1 week with minimal result Answer 23 D. Should be continued for at least 6 months before trying to stop Radioactive iodine Surgery usually not the tx of choice, but is always an option. Large goiter with compressive symptoms Question 24 A 35 yo male with a 10 year history of Crohns presents with nausea and vomiting after meals with increasing frequency. Antiperspirants should be recommended Treatment Freys Syndrome Post-gustatory sweating (Freys syndrome) is associated with parotidectomy Patients get perspiration/flushing overlying site of parotid gland Auriculotemporal nerve is the culprit. Question 27 A 18 yo football player is brought in after a tackle where he describes his leg being crushed. Common peroneal Paralysis Common Peroneal Nerve Nerve lies laterally below the knee and wraps around the head of the fibula Can be injured with trauma to fibular head or from compression of the lateral aspect of the knee joint Result is foot drop with diminished dorsiflexion of the ankle. Question 28 Which of the following is not a strong preoperative predictor of cardiac complications? Need for multiple agents to control hypertension Preop Predictors Cardiac Complications On test almost every year and widely missed The Goldman Index is the best recognized attempt at correlating cardiac sxs with periop complications It assigns a numeric grade to multiple risk factors.

It will not affect potency effective desyrel 100mg, It is feasible for an impassable stricture anywhere in the but it may be very embarrassing having semen coming urethra buy desyrel 100 mg fast delivery, even as high as the verumontanum. Make sure the perineum is washed and has formed, separate it, and ask him to keep the passage perfectly clean. The key to the operation is access, If the tip of the scrotal flap necroses, take it down, trim so the flap must go far back. Cut through the skin and it and resuture it; there is usually plenty of skin left. A proximal urethral fistula in the male is usually the Pass a Ch24 bougie down to the tip of the stricture, consequence of a periurethral abscess, but may arise and ask your assistant to hold it in the midline. Dissect the muscle from the bulb and penis, perianal region and inner aspects of the thighs reflect it on either side (27-11C). Sometimes a fistula forms between the urethra bougie (27-11D), and immediately insert a 4/0 continuous and the rectum. Try to delineate the stricture with a Incise until you have completely opened the stricture and urethrogram (38. Cut 1cm at a time, and control bleeding by continuing your haemostatic suture down each side of the split corpus spongiosum (27-11E). The only way to be sure about this is to pass your finger past the stricture, to make sure there are no strands of fibrous tissue remaining. This is normally a cystoscopic landmark, and is a posterior midline swelling in the urethral mucosa. It is just proximal to the external sphincter and the ejaculatory ducts open onto it. Then pass 5 interrupted 3/0 absorbable sutures through the flap onto the opened urethra (27-11G). Reinsert the speculum, and check that the edge of the flap is neatly up against the defect in the urethra, before completing the series of knots. Multiple put several more throws on each knot, and cut their free chronically infected and epithelialized fistulae have involved the ends. Withdraw the speculum and complete the work of penis, scrotum, perineum and thighs. A slow ooze of purulent discharge is more usual than the shower of urine shown here. Use fine monofilament to bring the edges of the scrotum to the edges of the urethra, previously exposed (27-11J). If the fistula is chronic, divert the urine by an open suprapubic cystostomy and excise the fistula track. If there are many, this may be impossible, forcing you to leave a permanent urinary diversion in place. If there is a congenital recto-urethral fistula, it is usually associated with an imperforate anus (33. A distal urethral fistula is usually the result of trauma, either from a crude circumcision, or from penile piercing with rings. A urethral fistula in women is invariably associated with a vesico-vaginal fistula (21. The combination of urine and infection produces severe oedema of the scrotum and abdominal wall. Untreated, the skin over the scrotum, penis, and anterior abdominal wall may slough. If renal function is impaired, as it often is after a long-standing stricture, extravasation may be fatal. However, from a defect in the more distal penile urethra the urine leaking is limited to the penis. The presence of microscopic depth of each wound in each direction, and suture them in haematuria is the most useful test. Allow inflammation to settle for at least 4-6wks; change the suprapubic catheter after 4wks. For example, they are common in North India and the Sudan, but are rare in East and Central Africa. Removing a stone, however, from the kidney or renal pelvis, is a task for an expert. Primary stones are most common in men of 30-50yrs, and usually form in the renal pelvis or else in the lowermost calyx. If it is small, and remains in the periphery of the kidney, or in a calyx, it may cause few symptoms; if it enlarges it may obstruct part of the kidney. A small stone <7mm diameter usually passes down the ureter, causes acute ureteric colic as it does so, and later is voided in the urine. If it is too big to pass, it may obstruct the upper end of the ureter, and cause hydronephrosis which will ultimately destroy the kidney.

In recent years buy desyrel 100mg without a prescription, expanding knowledge samples obtained by needle biopsy are smaller of the genetic defects that cause many and less satisfactory for electron microscopy purchase desyrel 100 mg. Muscle biopsy cannot differentiate between various neuropathic causes for wea kness. In Indications addition, there is the risk of sampling error in multifocal disease such as polymyositis. Needle biopsies are even more prone to miss patchy (as A muscle biopsy is indicated for investigation of in inflammatory myopathies) or endomysial etiology when a patient presents with clinical pathology. A muscle biopsy may also be usefulfor dia gnosis of systemic conditions that may have relatively silent muscle Risks manifestations such as vasculitis or sarcoidosis. This makes it most appropriately in patients with diabetes mellitus, superficial peroneal and occasionally the usefulto identify inflammatory changes in peripheral vascular disease, and significant superficial radial nerve. One segment is frozen for involvement in suspected multisystem identification of immune deposits; vasculitis, peripheral nerve may be the least immunocytochemistry studies are usefulto sta in invasive site for biopsy. The yield of biopsy is Preparation/Special for immunoglobulin and complement deposition. Another section is fixed in Limitations anticoagulation if present (after judicious glutaraldehyde for preparation for light consideration of risk/benefit ratio for doing so). Nerve fascicles are separated for However, patients should be apprised of what to single nerve fiber teasing, which allows detailed expect after the biopsy. Peripheral nerves respond to the myriad spontaneous paresthesias starting 24 to 48 demyelinating. This limits the by stretching of the proximal nerve stump by diagnostic utility of nerve biopsy in most patients certain movements or positions of the involved presenting with common types of neuropathy. Pain usual wanes by 2 to 3 weeks, but Indications should be emphasized that the diagnosis of lesser discomfort may persist for much longer. For sural nerve b iopsies, there is a for a specific cause of neuropathy, whic h may be an issue with nerve biopsy; sampling of a single sensory deficit along the lateral aspect of the diagnosed with certainty only by pathologic segment of a single nerve may miss multif ocal foot, which generally recedes or even resolves by examination. Conditions for which peripheral nerve biopsy is occur in the nerve proximal or distal to the site of most helpfulfor dia gnosis include: biopsy. In addition, nerve biopsy may fail to Vasculitis demonstrate significant pathology in small-fiber Sarcoidosis neuropathies. In that situation, skin biopsy to Miscellaneous Amyloidosis examine intraepidermal small nerve fibers may Tumor infiltration be a more powerfultech nique. New York: Oxford University (myelin-associated glycoprotein) hematoma, wound infection, and wound Press, 2001:90-123. It can also be painful, both dur ing the procedure and in the postoperative period. The appearance of x-ray imaged structures depends dilated pupils, bleeding diathesis, or Fastideal for uncooperative and critically ill on their density. Water is arbitrarily assigned the anticoagulation, and all penetrating head patients value of zero, with de nser structures like bone injuries. No ionizing Granulomatous disease Drug infusion pumpsgenerally not radiation is involved. T1W images are obtained after Direct multiplanar ima ging screws, nails, dental devices (e. Fat suppression No beam hardening artifacts related to bone joint replacements, spinal rods), ocular implants, images help identify lesions obscured by fat. Functional Limitations imaging such as diffusion and perfusion imaging is invaluable in evaluation of stroke. Often this is transient and eliminated by Many contraindications are relative; it is best to reassurance from the technologist. Magnetic resonanceimaging of the carcinomatosis, R/O drop metastases brain and spine, 3rd ed. These Instructions for Patients include arachnoid cysts, meningoceles, and arachnoiditis. Furthermore, with the exception of oral medications beginning spinal cord and associated nerve roots within myelography allows for the collection of spinal 4 hours pr ior to the exam. In patients with a prior the thecal sac via the intrathecal injection of fluid for analysis. Patients with poor renal sac and its contents allows for the indirect function who are not being dialyzed are hydrated diagnosis of extradural compression of spinal Limitations prior to the procedure. Glucophage (metformin) nerve roots and spinal cord as well as the should be withheld temporarily (48 hours) prior inference of intradural neoplasms, to myelography due to potential risk for renal arachnoiditis, and arachnoid cysts. Plain failure and reinstated only after renal function Myelography can depict spinal cord morphology myelography does not accurately depict nerve has been reevaluated and found to be normal. This information is often usefulfor and headache following the procedure, patients surgical planning especially in the cervical spine.
