We used endoscopic laser photocoagulation to treat neovascular glaucoma in eight eyes of seven patients. New vessels of the iris and anterior chamber disappeared or stabilized after photocoagulation in seven eyes (88%), while the vision improved in four eyes (50%). The endoscopy was excellent for observing the peripheral retina and ciliary process tissue. We found the endoscopic laser was suitable for wider photocoagulation of ischemic retina against media opacity.

BACKGROUND/AIMS: Patient-controlled sedation (PCS) allows the patients to titrate the dosages of sedative drug according to their needs. The objective of this study was to compare the safety and the efficacy of nurse-administered propofol sedation (NAPS) with those of PCS. METHODS: Eighty one patients were randomly assigned to two groups. All patients received meperidine 25 mg and propofol 40 mg as an initial dose for sedation. Patients in PCS group were subsequently infused with propofol 15 mg over 80 seconds through infusion pump whenever they required. Patients in NAPS group were injected with 10~20 mg propofol by nurse with supervision by endoscopist. The dosage of propofol, cardiopulmonary parameters, procedure time, sedation score, pain score, the patients' and endoscopists' satisfaction scores were assessed. RESULTS: With regard to blood pressure, pulse rate and oxygen saturation, serious complications were not observed. Especially, there was no significant difference of mean total dose between two groups (NAPS group and PCS group received 76.7+/-24.7 mg and 82.5+/-26.6 mg respectively). Pain score was higher in woman than in man (p=0.03). CONCLUSIONS: 1.2~1.5 mg/kg of propofol with small dose of opioid during colonoscopy was effective and safe. NAPS was more practical and useful method of sedation than PCS during colonoscopy.

The genetic diversity of Schistosoma haematobium remains largely unstudied in comparison to that of Schistosoma mansoni. To characterize the extent of genetic diversity in S. haematobium among its definitive host (humans), we collected S. haematobium eggs from the urine of 73 infected schoolchildren at 5 primary schools in White Nile State, Sudan, and then performed a randomly amplified polymorphic DNA marker ITS2 by PCR-RFLP analysis. Among 73 S. haematobium egg-positive cases, 13 were selected based on the presence of the S. haematobium satellite markers A4 and B2 in their genomic DNA, and used for RFLP analysis. The 13 samples were subjected to an RFLP analysis of the S. haematobium ITS2 region; however, there was no variation in size among the fragments. Compared to the ITS2 sequences obtained for S. haematobium from Kenya, the nucleotide sequences of the ITS2 regions of S. haematobium from 4 areas in Sudan were consistent with those from Kenya (> 99%). In this study, we demonstrate for the first time that most of the S. haematobium population in Sudan consists of a pan-African S. haematobium genotype; however, we also report the discovery of Kenyan strain inflow into White Nile, Sudan.

Pulmonary complications occur in 40~60% of patients who receive hematopoietic stem cell transplantation (HSCT) and are a source of substantial morbidity and mortality. Acute eosinophilic pneumonia (AEP) is an uncommon, non-infectious pulmonary complication occurring in HSCT recipients. We now report the case of a 52-year-old man with AEP who was treated with allogenic HSCT due to acute myeloid leukemia. He complained of fever, cough and dyspnea 390 days after allogenic HSCT. He also had skin and hepatic graft versus host disease (GVHD). Hypoxemia, diffuse pulmonary infiltrates on a chest x-ray and eosinophilia in bronchoalveolar lavage fluid were also noted in several tests. His symptoms, pulmonary infiltrates, hepatic dysfunction and skin lesions rapidly improved after treatment with corticosteroid therapy. Our case supports the idea that AEP is a late phase non-infectious pulmonary complication and one of the manifestations of chronic GVHD.
