Twenty variceal banding sessions were performed in eight patients between February 1995 and September 1996. A total of 69 rings were used to band the varices and at each session between two to six rings were used. Two of the eight had active bleeding and both underwent variceal banding to successfully arrest their bleeding as inpatients. Sixteen other variceal banding sessions were performed on an outpatient basis to obliterate their varices. Four of the eight patients had had sclerotherapy before and varices were still present. No acute or long term complications were noted. In one patient, variceal banding could not be performed as he developed stridor upon placement of the overtube. All the patients had advanced varices (Grade III or IV) and extended for more than 15 cms in the oesophagus. Endoscopic variceal obliteration remains the treatment of choice for patients with portal hypertension with variceal bleeding. Variceal banding is associated with a superior outcome when compared with sclerotherapy; the variceal kill time is shorter, infective complications less, rebleeding occurs less commonly and transfusion requirements are lower.

Nyang'aya, JA.  1982.  Efficiency of African charcoal burning stove . Abstract

Fuelwood accounts for most of the domestic energy use in the Third World. In East Africa the use of charcoal especially in urban centres has continued though threatened by social factors such as deforestation. The typical East African metal charcoal stove has been studied with emphasis on its efficiency and pollutant emission. The study has brought to better focus the very low performance figures and the dangerously high pollutant emissions by the stove. The study consisted of: i. Continuous flue gas monitoring which was achieved by positioning the stove in a specially constructed enclosure allowing sampling of the flue gases before dillution with the surrounding air. ii. Temperature monitoring of various .. posi tions both on and off the stove to assess the heat energy distribution. Following lighting up concentrations of over 3% CO and 8% CO were recorded each time. These concentrations reduced to about half the above values within 10 minutes though for up to 30 minutes the concentrations were still1\3 times above the.:poisonous ., threshold limit based on normal air. changes -wi thin an occupied room
