Severe but reversible encephalopathy associated with cefepime.

In this study, a report has been made of 19 cases of severe encephalopathy in patients with renal impairment who were treated during the last three years for various infections with cefepime, a new parenteral cephalosporin antibiotic. All patients (aged 57 to 91 years) presented a prolonged confusional state associated with diffuse rhythmic non-reactive triphasic sharp waves on the EEG. All the electroclinical symptomatology disappeared within 24-48 hours after discontinuation of drug administration.

Plasma 3 alpha-androstanediol glucuronide in normal children and in congenital adrenal hyperplasia due to 21-hydroxylase deficiency.

Monitoring therapy for congenital adrenal hyperplasia (CAH) due to 21-hydroxylase is difficult, although plasma determinations of 17 alpha-hydroxyprogesterone (17OHP), delta 4-androstenedione (delta 4A) and testosterone are helpful. We have studied the usefulness of monitoring plasma 3 alpha-androstanediol glucuronide (3 alpha-AG) in group of 24 CAH patients aged from birth to 18 years. For comparison, normal values for age and pubertal stage were determined in a control group of 115 girls and 118 boys.

High-resolution histocompatibility testing of a group of sixteen B44-positive, ABDR serologically matched unrelated donor-recipient pairs. Analysis of serologically undisclosed incompatibilities by cellular techniques, isoelectrofocusing, and HLA oligotyping.

We have characterized HLA incompatibilities in a group of 16 B44-positive patients who were serologically ABDR matched with their 23 (unrelated) potential bone marrow donors. After analysis with a combination of cellular techniques, IEF for HLA-A/B and oligotyping for class II and HLA-B44, 44% of the patients revealed one or more HLA incompatibility with at least one of their potential donors. CTL activity was detected in 12 of the 22 combinations tested.

Intrahepatic biliary lesions following blunt liver trauma in children--is nonoperative management or conservative operative treatment always safe?

Nonoperative management of blunt liver injuries has become standard care for children, in the absence of hemodynamic instability. However, attention has to be drawn to biliary complications which can manifest themselves after a latent period, even in the presence of rupture of main biliary ducts. Peripheral bile duct lesions are easily treated by wide drainage.

The addition of lipids increases the total parenteral nutrition-associated cholestasis in the rat.

Cholestasis is one of the most frequent complications of Total Parenteral Nutrition (TPN). Among the components of TPN, amino acids (AA) and dextrose are considered responsible in terms of quantity. The aim of this study was to determine whether IV lipids have a protective effect on the liver lesions induced by TPN, as well as on the bile flow in rats.

Bullous pemphigoid autoantibodies, HIV-1 infection and pruritic papular eruption.

Bullous pemphigoid (BP)-type autoantibodies were found by Western blot (WB) analysis of epidermal extracts in the serum of 38% of HIV-seropositive patients compared with 21% of HIV-seronegative patients with chronic pruritus and 76% of patients with BP. They were further identified as BP autoantibodies (BPab) by immunoprecipitation and immunoelectron microscopy. Their incidence increased from 21% in HIV infection stage II to 37% and 43% in stages III and IV, respectively.

Rapidly progressive hip osteoarthrosis--an unusual presentation of ochronosis.

A case of rapidly evolving osteoarthrosis of the right hip in a 65 year-old woman, as the presenting feature of ochronosis is described and literature reviewed. This unusual presentation may have been precipitated by an acute mechanical overload.

The subtalar sprain. A roentgenographic study.

Subtalar and ankle sprains are more frequently associated than previously suspected. In this study, 40 patients were analyzed, using subtalar arthrograms and ankle stress films. Thirty-two of the 40 patients had a rupture involving components of both subtalar and ankle capsuloligamentous structures.
