A history of surgery or radiation to the pelvis or extremity obviously would lead one to think that the swelling was secondary to injury or obliteration of the lymphatic vessels 100 mg vigora amex. The swelling from lymphedema generally starts at the level of the foot and ankle and progresses in a cephalad direction purchase vigora 100mg fast delivery. In the lower extremity purchase 100mg vigora, the edema usually involves the forefoot and spares the metatarsopha- langeal joint, so that, on lateral view, the foot and ankle resemble a buffalo hump. The edema usually does involve the digits, which rarely are involved when the edema is secondary to other causes. The edema may be pitting particularly early in the process, but it may lose the pitting with the onset of significant subcutaneous fibrosis. Unlike in venous insufficiency, the skin changes in lymphedema lack the dark pigment changes. Lymphedema certainly is part of the differ- ential of the patient in the case presented here, particularly if the patient provides a history of previous surgery or infection. Lymphoscintigraphy using radiolabeled albumin, gold colloid, and technetium colloid can be performed to assess lymphatic function and largely has replaced lymphangiography. The Swollen Leg 525 Treatment Lymphedema, whether it is primary or secondary, is a chronic condi- tion and has no cure. The primary goal of therapy is to decrease limb volume in order to reduce discom- fort, provide cosmesis, and avoid infection. The noninterventional methods of treating lymphedema represent the first line of therapy, and, in fact, they are used to treat the vast majority of patients. The therapeutic interventions include adequate skin care, elevation and compression of the extremity, the use of pneumatic compression garments, manual lymph drainage and ban- daging, the use of benzopyrones, and aggressive treatment of infec- tions. Benzopyrones, theoretically, act by increasing protein lysis by macrophages in the interstitium. This action may decrease limb volume moderately and improve the softness of the skin. The other modalities mentioned above attempt to reduce limb volume via mechanical com- pression or manual massage. The surgical forms of therapy, which generally are reserved for only the extreme cases, fall into one of two categories: physiologic or exci- sional. Examples of physiologic procedures include lymphangio- plasty, omental transposition, enteromesenteric bridge, lymphovenous anastomoses, and lympholymphatic anastomoses. It is important to note, however, that all of the above-mentioned procedures rarely are performed, and most vascular surgeons have seldom, if ever, per- formed any of them. Excisional procedures include total skin and subcutaneous excision, the Charles procedure, buried dermal flap, the Thompson procedure, and subcutaneous excision underneath flaps, the modified Homans procedure. Success rates are modest, in the range of 65%, and therefore these procedures should be reserved only for those patients who have not responded to measures that are more conservative. Some of the important points to remember when dealing with lymphedema are that the condition is chronic, some form of compres- sion garment is necessary, and any form of infection within the affected extremity should be treated aggressively. Patients need to be educated as to the signs and symptoms of infection and instructed to seek medical attention immediately if they develop signs of infection. Many physicians provide their patients suffering from lymphedema with a prescription for an appropriate antibiotic to avoid any delays in initia- tion of therapy. If the patient in the case presented has lymphedema, she should be treated conservatively with compression of the affected extremity and education regarding the signs and symptoms of infection. Ciocca Summary The presentation of a patient with a swollen leg is a rather common event. The etiology generally is related to a systemic, venous, or lymphatic abnormality. A thorough history and a thorough physical examination coupled with noninvasive testing lead to the appropriate diagnosis in the majority of cases. Ironically, a vascular surgeon frequently is consulted when a patient presents with a swollen leg. The role of surgery is limited in the treatment of patients with swollen legs, but it may be useful in small subsets of patients. A reasonable under- standing of the pathophysiology of the swollen leg as described in this chapter greatly assists a physician in making the correct therapeutic decisions regarding these sometimes difficult patients. To understand indications for and methods of biopsy, and to establish diagnoses for patients with skin lesions. To describe characteristics of nonmelanoma skin cancers (basal cell and squamous cell carcinoma). Cases Case 1 A 52-year-old woman presents with a lesion that has persisted for 1 year and slowly has become larger and more raised over time. Physical exam reveals a flesh-colored raised nodule on the left cheek at the nasolabial fold measuring approx- imately 7mm in diameter. The lesion has a pearly appearance and is smooth with rolled borders and surface telangiectasia. Wey Case 2 A 60-year-old man with a long history of sun exposure presents for evaluation of a nonhealing wound of the forehead of approximately 18 months’ duration. Physical examination reveals widespread actinic sun damage to the skin, with multiple scaly patches measuring 2 to 3mm. Facial skin is deeply wrinkled, with a few small tan macules 3 to 4mm in diameter.

The patient’s wife reports that he had an urgent desire to defecate when the pain began discount vigora 100mg with visa, but no further stool or flatus has been noted 100 mg vigora visa. She provides a list of current medications that includes digoxin purchase vigora 100 mg otc, pindolol (a beta-blocker), a baby aspirin, and a nitrate patch. Wise On examination, he appears gravely ill with cool ashen skin, an irregular pulse of 120, blood pressure of 85/50, and respirations at 28. Case 2 An 18-year-old male college student is awakened with an aching pain in the periumbilical area, anorexia, and nausea. He skips morning classes and chews a few antacid tablets, but, later in the day, the pain becomes worse, more constant, and moves to the right lower quadrant. Unable to eat, he vomits once and notes that the pain is worse when he tries to walk. At the hospital infirmary, he is found to have lower right quadrant tenderness, involuntary guarding, an oral temperature of 100. Case 3 A 59-year-old man is referred to the hospital emergency department by his physician because of lower abdominal pain, fever, and difficulty walking. The patient has noted intermittent cramps and changing bowel habits over the past 2 months. Recently, he has become constipated, but he also has had occasional episodes of diarrhea. For the past 18 hours, he has had constant, severe pain and soreness in the left lower quad- rant. Physical exam exhibits a blood pressure of 135/85, pulse of 100, and temperature of 39°C (102°F). There is mild, lower abdominal distention, but no scars or protuberances are noted. Palpation demon- strates involuntary guarding and tenderness in the left lower quadrant. A small amount of brown stool in the examining glove is negative for occult blood. Case 4 A 62-year-old African-American woman comes to the hospital emer- gency department complaining of severe, crampy, midabdominal pain that began approximately 36 hours ago. She simultaneously noted nausea that quickly was followed by multiple episodes of vomiting dark, thick, greenish fluid. The pain and vomiting have persisted, and she feels distended and unable to hold down fluids. She thinks her last bowel movement was 2 days ago and that she has not passed flatus over the past 24 hours. Abdominal Pain 377 about a week ago; her condition improved when she reduced her oral intake to clear fluids. On physical examination, she appears uncomfortable and rocks back and forth intermittently. Her blood pressure is 115/70, pulse is 80, res- pirations are 18, and temperature is 38°C (100. There is a well-healed, lower midline abdominal scar that she explains resulted from a complete hysterectomy per- formed 20 years ago. Her bowel sounds are hyperactive, with intermit- tent high-pitched whines and gurgles. Rectal examination demonstrates no masses or tenderness, and the ampulla contains no stool. An indicator of either functional or organic pathology of the abdominal wall and the intraab- dominal contents, it usually is mild, of short duration, and self-limited. Persistent, chronic, or recurrent pain usually can be evaluated safely by systematic observation and diagnostic studies over time and managed electively. On the other hand, severe abdominal pain that persists for 6 hours or longer must be diagnosed and treated promptly, as it may portend serious, life-threatening complications. The so-called acute abdomen has many causes and often requires timely surgical intervention to ensure the best clinical outcome. In most instances, the acute surgical abdomen is caused by one of three patho- logic processes: (1) inflammation that has extended beyond or perfo- rated the wall of the organ of origin; (2) acute vascular insufficiency (ischemia) or hemorrhage; (3) acute high-grade obstruction of the ali- mentary tract and ducts draining secretory or excretory organs. The general surgeon has become the specialist of choice for as- sessing patients with potentially serious abdominal problems. Is this a catastrophic event that requires immediate recognition, resuscitation, and emergency surgery to avert almost certain death? Severe, persistent abdominal pain associated with hemorrhagic, hypo- volemic, or septic shock, severe systemic sepsis unresponsive to anti- biotic therapy and fluid replacement, or the “board-like” abdomen of severe generalized peritonitis are typical presentations for these dis- astrous situations. Most of these cases present with signs of localized peritonitis and a mild to moderate systemic inflammatory reaction. Because the patient is at risk for or already has serious complications, here, too, a prompt and accurate diagnosis must be made. This is followed by a decision for relatively urgent surgery or initial, intensive medical care. Catastrophic Ruptured abdominal aortic aneurysm Intestinal infarction Free perforation Gastroduodenal ulcer Colonic diverticulitis or carcinoma Advanced suppurative ascending cholangitis Necrotizing infected pancreatitis Urgent Acute appendicitis Cholecystitis Diverticulitis Bowel obstruction Incarcerated hernia Complete small- or large-bowel obstruction Elective Biliary colic Partially obstructing colon carcinoma Crohn’s disease Nonsurgical Irritable bowel Gastroenteritis Simple pancreatitis Hepatitis Pelvic inflammatory disease Urinary tract infection/pyelonephritis Herpes zoster Diabetic ketoacidosis Myocardial infarction 3. Is this a transient or recurrent pain caused by a lesion that ulti- mately requires surgical removal, but that allows an orderly diag- nostic workup to be completed safely and an elective date to be set for the procedure? Is this a nonsurgical disorder such as irritable bowel syndrome or a self-limiting and medically treatable organic condition such as viral gastroenteritis or bacterial gastroenteritis? These are the causes of abdominal pain in the majority of patients; these patients are not considered for surgical therapy. The diagnosis of abdominal pain begins with the acquisition of sub- jective and objective data. As the clinical history is obtained and the physical examination is performed, it is important to determine if the patient’s pain is visceral or somatic in nature.

The Syncrometer is more accurate and versatile than the best existing testing methods. However at this point it only yields positive or negative results, it does not quantify. The chance of a false positive or a false negative is about 5%, which can be lessened by test repetition. It is in the public interest to know when a single bottle of a single product tests positive to a serious pollutant. If one does, the safest course is to avoid all bottles of that product entirely, which is what I repeatedly advise. These recommendations should be interpreted as an intent to warn and protect the public, not to provide a statistically significant analysis.
