A new clinical test in gastroduodenal perforation.

Forty-nine cases of gastroduodenal perforation were subjected to new air insufflation test. The clinical and radiological criteria of air insufflation test were applied to every patient of this study. Forty-seven cases (95.9%) were positive to the new test whereas 2 negative cases turned out to be old sealing perforation. The new test is highly useful in preoperative detection of site of perforation in perforative peritonitis.     

Malignant fibrous histiocytoma of the mediastinum

A case of malignant fibrous histiocytoma of the mediastinum presenting with unusual features of fever and leucocytosis is reported. This is the youngest patient reported in the literature who had this tumour in the mediastinum.     

ENDOSCOPY ASSISTED REMOVAL OF FERROMAGNETIC COINS WITH NOVEL MAGNETIC INSTRUMENT

Background: Ingestion of coins is a common clinical problem in children. Many of the coins are ferromagnetic and can be retrieved with the help of a magnet. We describe the use of a novel endoscopic accessory for removing ferromagnetic coins. Material and methods: Two magnet discs of 1.5 cm diameter were joined to a 200 cm steel wire of 0.75 mm thickness with a terminal 5 cm spring. A Teflon tube (160 cm, 7 F) was used along with this instrument as a sleeve. The use of this accessory was analyzed prospectively in subjects presenting with a history of coin ingestion. The time taken for removal of coins, complications during the procedure and failure rate was noted. Effect of the magnet on cardiac rhythm was also noted during the procedure. Results: A total of 55 children (mean age 5.1 ± 2.3 years) with coin ingestion presented over a period of 1 year. Forty‐four coins were ferromagnetic. All ferromagnetic coins were removed successfully. Mean time for removal was 68 ± 22 s. No complications were encountered. Conclusion: The novel magnetic instrument is precise, safe and quick for the removal of ferromagnetic coins under direct vision.     

Mortality in neonatal septicemia with involvement of mother in management.

In most Special Care Neonatal Units (SCNUs) in India, mothers are excluded from the care of their sick babies for fear of over-crowding and dislocation. We have attempted to study the feasibility of involving mothers in the care of their babies admitted for neonatal septicemia and to analyse whether this changed the sepsis related case fatality rate. The study material consisted of 158 neonates with blood culture positive neonatal septicemia whose mothers were actively involved in their care during their stay in the SCNU of LNJPN Hospital throughout 1987-88. The mothers lived in with their sick neonates and were extremely useful in feeding, cleaning, and monitoring for some important signs and symptoms. There were no epidemics of infection in the nursery during this period. All the babies discharged were receiving breast feeds, and the mothers were confident in taking care of them before discharge. The mortality in this group was 43%. The onset of septicemia was most often in the first week (36%) being 25.9% in second week, 26.6% in the third, and 11.4% in the fourth. Mortality was maximum (64.5%) when the onset of illness was in the first 3 days. Klebsiella and S. aureus were commonly isolated organisms (38.6 and 21.5%, respectively). Gram negative organisms were isolated in 66.5% cases with higher mortality in this group. Nearly 46% of the babies weighed 2 kg or less, with a mortality of 60.2% compared to 28.2% in those more than 2 kg. Only 3 to 5% and 40 to 66.7% of Gram negative and 23 and 70% of Gram positive organisms were sensitive to ampicillin and gentamicin, respectively.     

Fibronectin concentrations in plasma in peripheral vascular disease

Fibronectin (Fn) concentrations were measured immunoturbidimetrically in plasma of normal subjects and patients with peripheral vascular disease (PVD) before and after venous compression, which caused Fn concentrations to increase in both normal subjects and PVD patients. Basal Fn concentrations and those after 10-min compression were not significantly different in normal subjects and PVD patients. Five minutes after the release of compression, Fn had consistently declined in normal subjects and reverted to baseline values; in contrast, in PVD patients values either increased further or decreased inconsistently. Thus the Fn concentration at 15 min was significantly (P less than 0.001) greater in PVD patients than in normal subjects. Plasma albumin concentrations, measured in parallel to ensure that changes in Fn concentrations were not nonspecific, increased to a greater extent in normal subjects than in PVD patients and reverted to normal after the removal of compression. The Fn/albumin ratio remained unchanged in normal subjects after venous compression, whereas that in PVD patients increased and remained higher, even after decompression. The sustained increase in plasma Fn concentrations and in the Fn/albumin ratio in PVD patients after venous compression may indicate endothelial injury.
