Case Report: Cytomegalovirus Encephalitis in an HIV-Seropositive Person

The authors describe a previously healthy patient who required surgical resection of a large mucoid tumor lined with atypical columnar epithelium. The diagnosis was mucinous cystadenocarcinoma, a rare type of pulmonary cancer that is difficult to identify.

A 42-year-old woman returned from a 2-month stay in India with a rash and alow-grade fever. She also complained of fatigue, nausea, anorexia, and weightloss. Despite treatment with amoxicillin for a presumed streptococcal rash,her symptoms worsened. The pruritic rash spread over the patient’s body;only the face was spared.

The prevention of symptomaticcoronary heart diseaseand other vascular disordersrepresents a significanthealth care priority, especiallyin a population that is growingolder and more obese. However,a recent survey has shownthat many laypersons-and evensome physicians-do not know allthe target lipid levels that are associatedwith optimal reduction ofcardiovascular risk.

ABSTRACT: A 4-pronged approach that includes patient education, skin and nail care, appropriate footwear, and proactive surgeries can effectively prevent diabetic foot problems. Teach patients with diabetes to examine their feet daily to detect new onset of redness, swelling, breaks in the integrity of the skin, blisters, calluses, and macerated areas. Have them follow a daily foot care regimen that includes warm water soaks and lubrication, and have them keep toenails properly trimmed. Recommend that patients select shoes that fit properly and have sufficient padding and toe box space; have them use inserts, lifts, orthoses, or braces--as recommended-to correct abnormal gait patterns. Finally, if deformities develop, simple proactive surgical procedures can correct these problems before they result in the development of wounds.

ABSTRACT: In patients with jaundice and normal liver function, the cause of hyperbilirubinemia is an isolated disorder of bilirubin metabolism. In patients with hyperbilirubinemia who have abnormal liver enzyme levels, hepatocellular disease must be differentiated from cholestatic liver injury. In general, if the cause of jaundice is global hepatocellular dysfunction, the serum alanine aminotransferase and aspartate aminotransferase levels will be predominantly elevated. If the cause is cholestasis, the serum alkaline phosphatase and gγ-glutamyl peptidase levels will be elevated. In most patients, imaging studies will be needed. The initial workup should include abdominal ultrasonography, which can identify dilated intrahepatic and extrahepatic biliary ducts as well as findings that may suggest cirrhosis or signs of portal hypertension, including splenomegaly and ascites.

BOSTON -- Daily use of over-the-counter analgesics -- including aspirin -- significantly increased the risk that men will develop new-onset hypertension, researchers here reported.

WALTHAM, Mass. -- Pulse pressure, the difference between systolic and diastolic pressures, may be a risk factor for the onset of atrial fibrillation independent of arterial pressure and other known factors, researchers said.

DALLAS -- All women 65 or older, regardless of health, should be considered for daily low-dose (81 mg) aspirin therapy to protect their hearts, according to new American Heart Association guideline.

ANN ARBOR, Mich. -- When preschoolers dive into snacks in large groups, they may eat more than when the snacks are offered to smaller groups, researchers here found.

NOTTINGHAM, England -- Second-hand cigarette smoke leaves a suspicious trail of cardiovascular-disease biomarkers in non-smokers, found a large cross-sectional study here.

BOSTON -- Two new risk factors added to the traditional risk model enhanced prediction of a woman's 10-year risk of cardiovascular disease or stroke, researchers reported.

EVANSTON, Ill. -- Children who get less sleep than recommended are significantly more likely to be overweight or obese than their peers who get the right amount of sleep.

ROCKVILLE, Md. -- The FDA today approved over-the-counter sale of a low-dose version of Xenical (orlistat), a prescription diet drug that works by blocking the absorption of fat in the intestine. The OTC version will be called Alli.

HERSHEY, Pa. -- For women with polycystic ovary syndrome the fertility drug clomiphene proved superior to metformin, a diabetes drug. in achieving a live birth, researchers found in a head-to-head study.

WINSTON-SALEM, N.C. -- If patients are overweight or obese when they reach age 70, matters will probably get worse over the next decade, when aging bodies gain fat and lose lean mass in these vulnerable years, researchers reported.

Furunculosis is a deeper infection of the hair follicle generally attributable to S aureus.

Declining cardiovascular function, poor circulation, diabetes, obesity, cancer, immunodeficiency, renal disease, and thinned, xerotic skin provide the setting for a host of bacterial infections in elderly persons that can involve any level or structure of the skin.

A 49-year-old white man, in whom HIV infection had been newly diagnosed (CD4+ cell count, 25/µL; HIV-1 RNA level, 274,000 copies/mL), was transferred to our hospital for further workup and treatment of multiple neurologic deficits. He had presented to another hospital with a 4-day history of left-sided weakness and numbness, left-sided facial droop, dysphonia, and dysphagia that led to the initial diagnosis of an acute stroke.

Blastoschizomyces capitatus is an emerging pathogen that causes infection primarily in patients who have immune system dysfunction. The author reports a case of pulmonary blastoschizomycosis in an immunocompetent man who was successfully treated with voriconazole.

A 75-year-old woman had undergone a total thyroidectomy, with histologic evidence of poorly differentiated follicular thyroid cancer. She subsequently received an ablative dose of iodine-131. After a disease-free interval of about 2 years, she presented with evidence of recurrence in the thyroid bed. She had enlarged cervical lymph nodes and complained of dyspnea on exertion.

A 69-year-old man with a history of atrial fibrillation, pulmonary embolism, asthma, and obstructive sleep apnea presented to the emergency department for evaluation of dyspnea and light-headedness. He had been treated for paroxysmal atrial fibrillation over the past 5 years; fairly good control had been achieved with metoprolol and amiodarone. However, over the past several months, he had been experiencing intermittent episodes of atrial fibrillation.

ABSTRACT: Angiotensin-converting enzyme (ACE) inhibitor therapy is recommended for all patients with heart failure (HF) and a reduced ejection fraction. It is generally initiated in the hospital at low doses as inotropic therapy is tapered. Angiotensin II receptor blockers may be a suitable alternative for patients who cannot tolerate ACE inhibitors. For patients who cannot tolerate either class of drug, a combination of hydralazine and a nitrate is recommended. ß-Blockers are first-line therapy for patients with current or previous symptoms of HF and reduced left ventricular function, as well as all patients hospitalized for HF. An aldosterone antagonist may be added to the regimen of patients with moderately severe to severe symptoms and reduced ejection fraction whose renal function and potassium concentration can be monitored.

ABSTRACT: Heel pain that occurs with the first several steps in the morning and diminishes as walking continues is the classic symptom of plantar fasciitis. Assessment of risk factors, such as improper footwear, a change in physical activities, and a new running surface, is important. Radiographs are rarely useful. Plantar fasciitis is generally self-limited; symptoms typically take 6 to 18 months to resolve. Conservative measures may include relative rest, stretching, strengthening, shoe modifications, orthoses, night splints, NSAIDs, and ice therapy. A corticosteroid injection may be warranted in resistant cases. If extensive conservative treatment is unsuccessful, referral to an orthopedic surgeon may be indicated.

A 48-year-old woman is evaluated for transfer to the ICU. She presented to the emergency department 48 hours ago with severe abdominal pain and emesis. The pain had started several days earlier and was located in the upper abdomen with some radiation to the back. No position--even the fetal position--provided relief. After admission, she was given intravenous fluids and analgesics; in the last several hours, her condition has deteriorated. She now complains of thirst and is somewhat agitated.
