Diazepam and meperidine on arterial blood gases in patients with chronic obstructive pulmonary disease.

Arterial blood gases were not significantly altered by 0.15 mg/kg intravenous dose of diazepam in patients with chronic obstructive lung disease. The PalphaO-2 was significantly reduced and the P-alphaCO-2 increased after administration of 1.5 mg/kg meperidine intravenously and the combination of 1.5 mg/kg meperidine with 0.15 mg/kg diazepam. Diazepam did not, however, significantly increase the ventilatory depression induced by meperidine. Therefore, 0.15 mg/kg diazepam intravenously causes no ventilatory depression by meperidine in patients with chronic obstructive lung diseases.

Bullous pemphigoid in infancy: case report and literature review.

We report a 2-month-old girl who developed bullous pemphigoid on her hands and feet shortly after receiving her routine immunizations. Infantile bullous pemphigoid has a clinical presentation distinct from bullous pemphigoid seen in older children and should be included in the differential diagnosis of blisters involving the hands and feet. Our patient responded well to topical corticosteroid therapy.

Use of trimethoprim-sulfamethoxazole to prevent bacterial infections in children with acute lymphoblastic leukemia.

We assessed the efficacy of prophylactic antibiotics in children receiving intensive chemotherapy for acute lymphoblastic leukemia. The patients were randomized to receive either trimethoprim-sulfamethoxazole (TMP-SMX) or placebo in a double-blind trial. Thirty patients were evaluated in each group. Children receiving TMP-SMX had fewer episodes of bacteremia (0 vs. 5) and otitis media (3 vs. 18). The geometric mean of the neutrophil nadir was 172 in the TMP-SMX group and 287 in controls. However, no increased delay or dose reduction of chemotherapy was observed in the TMP-SMX treated patients. Five patients who received TMP-SMX developed Gram-negative rods resistant to TMP-SMX on surveillance stool cultures. We conclude that TMP-SMX prophylaxis decreased certain bacterial infections in children with acute lymphoblastic leukemia without causing clinically significant toxicity. The emergence of Gram-negative rods resistant to TMP-SMX in treated patients suggests that TMP-SMX prophylaxis should be restricted to patients who are at high risk for developing a bacterial infection or Pneumocystis carinii pneumonia.

Lyophilization closures for protein based drugs.

Rubber stopper formulations which are currently used as lyophilization stoppers vary widely in their capacities to absorb and release moisture. Release of moisture from the stopper over the shelf life of the product may result in drug degradation for extremely low cake weight products. The degree to which rubber formulations absorb water is dependent upon the components of these formulations. Independently, polymers and fillers absorb water during autoclave cycles to varying levels depending upon such factors as the solubility, structure, possibility of chemical reactions and impurity levels of these materials. Once combined into a stopper formulation, the raw materials can react to form species which further promote absorption. Data is presented comparing the absorption characteristics of low versus high absorbent rubber formulations. The release of moisture from these formulas when stoppered on vials containing dry product is also discussed.
