Diagnosis of abdominal tuberculosis by transabdominal ultrasound-guided needle biopsy.

Laparotomy and laparoscopy have been used for biopsy of pelvic masses in the differential diagnosis between abdominal tuberculosis and ovarian cancer. We suggest the use of transabdominal needle biopsy under ultrasound guidance in such cases. Two women developed abdominal distention, one of whom had been receiving medical treatment for known tuberculosis. In both cases, ultrasonography showed a pelvic mass and ascites associated with high levels of CA 125. A transabdominal ultrasonographically-guided biopsy of the masses with a trucut needle established their tuberculous origin. The transabdominal sonographic needle biopsy is a reliable diagnostic procedure in the differential diagnosis between abdominal tuberculosis and ovarian malignancy. This minimally invasive procedure saves the patient with tuberculosis from unnecessary laparotomy.

Nitrofurantoin-induced immune-mediated lung and liver disease.

A 60-year-old woman with multiple sclerosis and recurrent urinary tract infections (UTI) was evaluated for the recent onset of a dry cough, dyspnea on exertion, and jaundice. Investigation demonstrated interstitial lung disease with bilateral infiltrates and unilateral effusion, as well as a severe chronic active hepatitis with marked fibrosis. Other notable features were positive antinuclear antibodies and anti-smooth-muscle antibodies and the absence of any possible cause except for nitrofurantoin treatment (Macrodantin, 100 mg/day), which the patient had been taking for the previous 3 years as a prophylactic measure against UTI. The patient died of pneumococcal septicemia less than 30 days after presentation. Pulmonary or hepatic injury caused by nitrofurantoin treatment is rare; their combined occurrence is hardly ever described. Combined drug-induced pulmonary and hepatic toxicity is reviewed and should be considered early in the differential diagnosis to allow reversibility and avoid serious outcomes.

Idiopathic calcitriol-induced hypercalcemia. A new disease entity?

We describe 3 patients with a prolonged history of hypercalcemia. The patients did not take any vitamin supplements. All patients had low parathyroid hormone (PTH), high calcitriol (1,25(OH)2D3), and high angiotensin-converting enzyme (ACE) blood levels. There was no evidence of sarcoidosis of any other underlying disease in the results of an extensive workup. Treatment with prednisone resulted in normalization of calcium levels in all patients. They remained dependent on low-dose prednisone on a subsequent prolonged follow-up.

[Sweet's syndrome in a young woman].

Sweet's syndrome is an uncommon and dramatic skin disease associated with systemic symptoms such as fever, headache and arthralgia. Since it is also accompanied by an increased erythrocyte sedimentation rate and leukocytosis, it may be confused with severe systemic infections and other systemic illnesses. We describe a 30-year-old woman who presented with typical features of the disease. They included high fever, headache, sore throat, increased sedimentation rate, and a painful violaceous, nodular and papular rash on her limbs and upper trunk. Histologic features included dense neutrophilic infiltration and edema of the dermis, with foci of leukocytoclasia, but without leukocytoclastic vasculitis. There was a dramatic repose to treatment with prednisone.
