PULMONARY OEDEMA FOLLOWING AIRWAY OBSTRUCTIN IN A PATIENT WITH HODGKIN'S DISEASE

We report a case of pulmonary oedema follwing airway obstructionin a patient who underwent biopsy of a tumo ur in volving theanterior mediastinum and neck. The occurrence of airway obstructionin patients with anterior mediastinal masses, and the pathogenesisof pulmonary oedema occurring in association with airway obstruction,are discussed.     

C-reactive protein as a predictor of fetal and maternal infective morbidity and fetal mortality

The value of maternal C-reactive protein (CRP) levels as predictors of fetal and maternal infective morbidity and fetal mortality was assessed prospectively over a 6-month period in all cases of premature rupture of the fetal membranes or suspected premature labour. Statistical analysis of results showed that CRP at a level of 1.32 mg/dl is a sensitive marker of infective morbidity in mother and neonate. Furthermore, there was a significant association between raised CRP levels and low-birth-weight babies, suggesting that intra-uterine infection is a major cause of prematurity in the study population.     

346. Die bedeutung von stenosen an gefä\verzweigungen. eine experimentelle untersuchung an der femoralisgabel unter besonderer berücksichtigung der indikation zur profundaplastik

Zusammenfassung In einem pulsatil mit Kochsalz durchströmten Modell der Femoralisgabel wurden Flussmessungen und Druckgradienten für Flussmengen von 170 bis 860 ml/min bei peripheren Widerständen von 232 bis 25 792 dyn s cm^–5 über dem Superficialis- und Profundaabgang bei Stenosen von 1 cm Länge und Querschnittsverminderungen von 0% bis 100% gemessen. Bei grossen Flussmengen (800–860 ml/min) und kleinem peripheren Widerstand (<640 dyn s cm^–5) lag die kritische Stenose am Profundaabgang bei 4,1 mm Durchmesser, für hohe periphere Widerstände (> 5 072 dyn s cm^–5) bei 2,6 mm; bei kleinen Flussmengen (<400 ml/min) betrug der kritische Durchmesser 1,8 mm. Der nicht stenosierte Profundaabgang stellte für keine der Versuchsbedingungen ein strömungsdynamisches Hindernis dar.     

Provision of immunisation--the Gazankulu experience

Following the outbreak of poliomyelitis in Gazankulu in 1982, the immunisation services in Gazankulu were thoroughly examined. As a result of this, a comprehensive immunisation policy for Gazankulu was accepted in November 1986. The broad aim of the policy is to provide effective immunisation to all Gazankulu residents against tuberculosis, diphtheria, pertussis, tetanus, poliomyelitis and measles. A specific objective is that by the end of 1987, 85% of under-5s should have been vaccinated against these six diseases and by the end of 1990 this percentage should be 97%. The detailed strategies to reach these objectives are highlighted. Within the framework of the objectives, the policy allows different areas to formulate individual strategies. Programme monitoring and community involvement are two crucial aspects of the policy and these are discussed in detail. The early successes and difficulities in implementing this policy are discussed.     

Renal Aspergilloma--A Case Illustrating the Problems of Medical Therapy

The second documented case of renal aspergilloma due to Aspergillusflavus is presented. The merits of the medical therapy thatfailed are discussed. Pathological examination showed a nidusof aspergillus around suture material persisting from a pyelolithotomyoperation 2 years before in India. We argue that this was thereason for the failure of the medical therapy. This is the firstcase of its kind reported.     

Rapid action of 1,25-dihydroxyvitamin D3 on calcium transport in perfused chick duodenum: effect of inhibitors

Transport of 45Ca from the lumen to the venous effluent was studied in duodena of normal, vitamin D3-replete (+D) chicks perfused through the celiac artery with 130 pM 1,25(OH)2D3 or vehicle. Administration of actinomycin D 3 h prior to perfusion did not alter the unstimulated transport rate or diminish the response to exogenous 1,25(OH)2D3: After 40 min exposure to the seco-steroid, 45Ca in the vascular effluent was 140% of control levels. The anti-microfilament agent cytochalasin b and the ionophore monensin, an inhibitor of Golgi function, similarly failed to suppress 1,25(OH)2D3-stimulated calcium transport. In pilot studies, Golgi and basal-lateral membrane fractions were prepared from duodenal epithelium of vitamin D-deficient (-D) chicks treated with vehicle or 650 pmol of 1,25(OH)2D3 in vivo 2 h, 10 h, or 15 h before sacrifice, as well as from +D birds. Analyses of Golgi fractions for cathepsin B (CB) activity revealed a biphasic response with time, increasing to 200% of -D levels 2 h after 1,25(OH)2D3 administration and in equivalent preparations from +D birds. Less pronounced increases in acid phosphatase activity were observed in the same membrane fractions. In basal-lateral membranes, enhanced CB activity was detectable 10 h after 1,25(OH)2D3 in vivo, rose to 155% of -D levels at 15 h, and to 245% of controls in fractions from +D birds, whereas acid phosphatase was 75%, 81%, and 125% of controls, respectively, at these times.(ABSTRACT TRUNCATED AT 250 WORDS)
