Emergency embolization of spontaneous ruptured hepatocellular carcinoma: Correlation between survival and Child−Pugh classification

From February 1994 to April 2000, 29 emergency gelfoam embolizations for spontaneous ruptured hepatocellular carcinoma (HCC) performed in 28 patients were retrospectively reviewed. There were 11 patients in Child's A , 11 in Child's B and six in Child's C classification of cirrhosis. The duration of the procedure, artery embolized and complications were reviewed, and the Child?Pugh classification of each patient was correlated with their mean survival period. Embolization was done in 12 right hepatic arteries, two left hepatic arteries and 15 proper hepatic arteries. In one patient, the left hepatic artery was embolized initially but the proper hepatic artery was also embolized because another subcapsular liver tumour was found after reviewing the preangiogram CT scan. The entire procedure took 40?170 min (mean = 86 min) with no periprocedural complication. Following embolization, the mean survival period for Child's A class was 218.3 days, Child's B class was 83.4 days and Child's C class was 11.0 days. Transcatheter embolization is an effective treatment to arrest bleeding in spontaneous ruptured HCC. Patients with Child's A class cirrhosis have the longest survival. Selective embolization of either the right or the left hepatic artery alone carries the potential risk of missing multifocal HCC that might not be easily appreciated during angiography.     

OFLOXACIN VERSUS TRIMETHOPRIM AND CO-TRIMOXAZOLE IN THE TREATMENT OF UNCOMPLICATED URINARY TRACT INFECTION IN GENERAL PRACTICE

A large-scale, randomised, multicentre single-blind clinical trial was conducted to assess the comparative efficacy and tolerance of ofloxacin, trimethoprim and co-trimoxazole in the treatment of uncomplicated urinary tract infection in general practice. A total of 1,069 patients from 76 centres across the UK were enrolled in the study, and randomised to one of the following treatment groups: ofloxacin (200 mg od), trimethoprim (200 mg bd) or co-trimoxazole (trimethoprim 160 mg and sulphamethoxazole 800 mg bd). Each patient received five days of medication. Clinically, ofloxacin was as effective as trimethoprim and co-trimoxazole. However, the bacteriological cure rate was significantly better for ofloxacin, with eradication of the initial causative pathogen by the end of treatment in 92% of patients in the ofloxacin group, compared with 81% for trimethoprim and co-trimoxazole (P = 0.0002). There was also a lower relapse rate for ofloxacin. Ofloxacin was well tolerated: adverse events were reported by 67 (12.4%) patients in the ofloxacin group, compared with 48 (18.7%) patients in the co-trimoxazole group and 37 (13.6%) patients in the trimethoprim group. Ofloxacin can therefore be considered a suitable alternative for the treatment of uncomplicated urinary tract infection.     

Arthrography in the evaluation of the temporomandibular joint

Temporomandibular joint arthrography has been helpful in selecting patients for reconstructive surgery who have severe temporomandibular joint dysfunction. Structural abnormalities of the soft tissues can be demonstrated where only minimal osseous changes are seen on tomography. The normal arthrographic anatomy of the joint is reviewed and normal and pathological joints are illustrated.     

The pathogenesis of peripheral aneurysms of the central nervous system: a subject review from the AFIP

Most central nervous system aneurysms occur around the circle of Willis, and are congenital or arteriosclerotic in origin when in that location. Peripherally located aneurysms are either idiopathic or secondary to infection, tumor embolus (from choriocarcinoma and cardiac myxoma), Moyamoya disease, or trauma. The pathophysiologic features of these aneurysms are discussed.
