Shunt Removal

Abstract Six patients with glomerulonephritis in association with a ventriculovascular shunt were treated with three basic modes of therapy. Direct intraventricular instillation of antibiotic was used on seven occasions in five patients either as the definitive mode of therapy or as an adjunct to shunt removal. Ventricular fluid antibiotic concentrations were monitored in two patients and demonstrate that effective levels as compared to the specific minimal inhibitory concentration can only be achieved by this method. With resolution of the shunt infection, improvement in the clinical and laboratory parameters of renal function was noted. A recommended treatment protocol is outlined, including specific dosages for intraventricular antibiotics. The need for detailed and frequent post-treatment examination including serum immunoglobulin profile is stressed.

Nghiên cứu được tiến hành nhằm xác định nồng độ ức chế tối thiểu (Minimal Inhibitory Concentration - MIC) của một số loại kháng sinh đến vi khuẩn phân lập được từ cá dìa thương phẩm mắc bệnh lở loét (Siganus guttatus). Từ kết quả phân lập định danh cho thấy 2 chủng Vibrio parahaemolyticus VPMP22 và Vibrio tubiashii ATCC 19109 có mặt trên các vết lở loét ở cá dìa thương phẩm. Kết quả thử nghiệm MIC cho thấy các loại kháng sinh Cefuroxim, Cefotaxim, Tetracycline, Erythromicin, Rifamicin có nồng độ ức chế vi khuẩn Vibrio parahaemolyticus VPMP22 tốt nhất dưới 0.21 µg/ml. Các kháng sinh có Cefuroxim, Cefotaxim, Oxytetraciline, Erythromicin, Trimethoprim nồng độ ức chế vi khuẩn Vibrio tubiashii ATCC 19109 tốt nhất dưới 1.25 µg/ml. Penicillin có nồng độ ức chế tối thiểu cao nhất đối với cả 2 chủng vi khuẩn trên (80 µg/ml), cho thấy 2 chủng vi khuẩn trên đã có sự kháng thuốc đối với loại kháng sinh này. Do đó, trong phòng trị bệnh lở loét trên cá dìa nên sử dụng Cefuroxim và Cefotaxim để có hiệu quả cao nhất trong phòng trị bệnh.

The toxicity of the first ten MEIC chemicals to Escherichia coli and Bacillus subtilis was examined. Nine of the chemicals were toxic to the bacteria, with the minimal inhibitory concentration (MIC) ranging from 10-3 to 4.4M. The sensitivities of both organisms were similar, but the effect on E. coli was often bactericidal, while it was bacteriostatic for B. subtilis. Digoxin was not detectably toxic to either bacterial species. Amitriptyline and FeSO4 were relatively less toxic to the bacteria than to human cells. For seven chemicals, a highly significant linear regression was established between log MIC in bacteria and log of blood concentration, giving lethal and moderate/mild toxicity in humans, as well as with toxicity to human lymphocytes.

Object The authors present their experience with a protocol for the treatment of patients with complicated shunt infections. Methods Complicated shunt infections are defined for the purpose of this protocol as multiple compartment hydrocephalus, multiple organism shunt infection, severe peritonitis, or infections in other sites of the body. The initial treatment protocol for these patients was 3 weeks of intravenous antibiotic therapy and 2 weeks of twice daily intraventricular/intrashunt antibiotic therapy. Cerebrospinal fluid (CSF) cultures were monitored during therapy and obtained again 48 hours after completion. The shunt was completely replaced. Additionally, follow-up cultures were obtained in all patients 3–6 months after therapy was completed. Results A cure of the infection was achieved in all patients as defined by negative cultures obtained at completion of antibiotic therapy and in follow-up studies. The follow-up period was 2–11 years (mean 4.4 ± 2.5 years). The treatment protocol was modified in the patients treated after 1991, and 18 patients were treated with this modified treatment regime. In these patients, intraventricular antibiotics were administered only once daily for 14 days, and the CSF was cultured 24 hours after antibiotic therapy had been stopped instead of after 48 hours. The results were similar to those obtained with the initial protocol. Conclusions Based on their prospective nonrandomized series, the authors believe that patients with complicated shunt infections can be successfully treated with 2 weeks of intraventricular antibiotic therapy administered once daily, concurrent with 3 weeks of intravenous antibiotic therapy. This protocol reduces length of treatment and hospital stay, and avoids recurrence of infection.

Jaw Osteonecrosis

The bisphosphonates are synthetic substances of inorganic pyrophosphate that have been the basis of treatment of patients with osteolytic diseases, such as multiple myeloma, malignant hypercalcemia, Paget's disease, or patients with bone metastases. Its main pharmacological effect is inhibition of bone resorption caused by osteoclasts, which have a reduced function. Their adverse effects are infrequent but include pyrexia, impaired renal function, hypocalcemia, and more recently, maxillo-mandibular ostenecrose induced bofosfonatos. In this report we describe a clinical case of jaw osteonecrosis induced by bisphosphonates in patient with chronic kidney disease and the treatment protocol performed.
