Large volume paracentesis and intravenous dextran to treat tense ascites.

Forty patients with cirrhosis of the liver and tense ascites were randomized to receive either aldactone 400 mg/day and furosemide 80 mg/day (n = 20) or repeated large volume paracentesis (LVP) and infusion of low molecular weight dextran (n = 20). Both treatment groups were similar in clinical and laboratory parameters. Complete mobilization of the ascitic fluid was achieved in all receiving LVP and dextran therapy within 1 week of the treatment, in contrast to the minimal mobilization of the ascitic fluid in patients receiving diuretics even after 2 weeks of therapy. Renal function, the clinical parameters of systemic hemodynamics, serum electrolytes, and hepatic function remained stable in patients receiving LVP and dextran and were similar to those in the diuretic-treated patients. We found no deterioration of these functions in the nonedematous patients treated by LVP and dextran even though the protective effect of edema against LVP was lacking in them. Plasma volume estimation in six nonedematous cirrhotic patients treated by LVP and dextran did not reveal any hypovolemia after complete mobilization of ascites. The frequency of complications and death were similar in the two groups. Dextran infusion is a safe, effective, and low-cost replacement therapy in patients with cirrhotic ascites treated by LVP.

Infantile hemangiopericytoma of nasal cavity.

Hemangiopericytoma is an uncommon vascular tumour. Of the 26 intranasal hemangiopericytomas reported in the English literature only two paediatric cases have been noted. A benign course is more common in the nose and paranasal sinuses. A pre-operative diagnosis being not possible, definitive treatment cannot be preplanned. Wide surgical excision by a lateral rhinotomy approach is still the treatment of choice. The appropriate investigations and treatment line followed are described. A lifelong followup is mandatory.

Drill biopsy in the diagnosis of lung lesions.

A high speed pneumatic drill was used to perform 190 percutaneous transthoracic biopsies in 161 patients. The resultant cores of tissue provided a definite diagnosis in 146 patients, giving a success rate of 90.7%. Complications occurred in 58 patients, subcutaneous emphysema being the most common, though only seven patients required active treatment, giving a rate of 3.7% for important complications. One patient died within 24 hours of the biopsy procedure owing to asphyxia resulting from aspiration of the contents of an acutely dilated stomach. Our experience clearly establishes that the drill biopsy as used by us is simple and safe and can be carried out in an outpatient department, yielding better overall results than any other procedure for closed biopsy of the lung currently practised.
