ABSTRACT
The current management of diseases of urinary bladder requiring resection is by augmentation cystoplasty or transplantation of ureters. Transplantation of ureters is associated with morbidity and mortality. Ideal management will be by regenerating urinary bladder in vivo. Neo-regeneration of tissues and organs like abdominal wall, aponeurosis etc., has been attempted and patented. After neo-regeneration of mesoderm tissues and organs, regeneration of urinary bladder (developed from endoderm) was. In vivo surgical techniques were developed in dogs. It is known that the embryonic morphogenesis of urinary bladder is from uro-genital sinus of hind gut. A membrane, containing endoderm stem cells in crypts of recto-sigmoid colon, was surgically isolated and colonized with remnant of urinary bladder wall after extensive resection. Experimental study was performed in dogs, for 60 days to one and a half year. Regeneration of all the layers of tissues of the wall of urinary bladder was observed. The neo-regeneration phenomenon has been recognized as “desired metaplasia”. The regenerated neo tissue/organ on histological examination and cystometry studies was found compatible with normal urinary bladder. The hypothesis, neo-regeneration and desired metaplasia, is discussed.
ABSTRACT
OBJECTIVE: The emergence of penicillin and macrolide resistant strains, responsible for Acute Lower Respiratory Tract Infections in children has offered third generation cephalosporins the platform to perform. The aim of the present study was to evaluate two third generation oral cephalosporins for their empirical use in community acquired lower respiratory tract infections in pediatric patients. An assessment of the clinical cure and bacteriological eradication rates and an overall tolerability was made. METHODS: It was a prospective, open, comparative, multicentric study. 776 children (Mean age 10 years) with LRTIs were included and randomly allotted to two groups respectively. A total of 396 children were given cefpodoxime susp 5 mg/kg b.i.d. and 380 patients on cefixime 4 mg/kg b.i.d. for 10-14 days. RESULTS: At the end of therapy, the clinical success with cefpodoxime was 97% as against 86.8% with cefixime. Bacterial eradication was 93.4% with cefpodoxime and 82.9% with cefixime. CONCLUSION: Cefpodoxime has been found to be a well-tolerated and superior alternative to cefixime synergistically documenting the extended spectrum of activity.

With the aim of reducing myocardial infarction size, isosorbide dinitrate (ISDN) was tried in 27 patients of acute myocardial infarction (AMI). There was 11% reduction of infarction size, in the ISDN treated group, in comparison to that of non treated group, though the result was not statistically significant. But, many of the in-hospital complications were significantly less in the treated group. After a critical analysis of the result it was concluded that a statistically insignificant result, as regard reduction of infarction size in AMI, cannot always exclude the utility of a drug therapy in AMI.

Generalised abnormalities have been described previously in familial and bilateral retinal detachment 1.2.3. Some studies have shown the presence of specific histological skin changes in cases of retinal detachment per se as well as in other syndromes having associated retinal detachment, hence pointing towards a generalised abnormality of constitution3.9.12. Drawing an analogy from these observations, the aim of our study was to study the histological changes in the skin of patients with rhegmatogenous retinal detachment and to relate its a etiopathogenesis to a generalized abnormality.

Twenty patients with Rhegmatogenous retinal detachment were subjected to applanation tonometry and Corneal Thickness measurement to ascertain (i) the change in central & peripheral corneal thickness and (ii) effect of Intra Ocular Pressure on these corneal changes. Twenty age and sex matched controls also underwent similar investigation. It was observed that both the mean Intra Ocular Pressure and the corneal thickness (both Peripheral Corneal Thickness and Central Corneal Thickness] of the affected eye showed statistically significant reduction (P 0.001) when compared to Intra Ocular Pressure and Corneal Thickness changes of fellow-eyes and eyes of control subjects. In addition to these even the fellow eyes which had normal Intra Ocular Pressure, showed statistically low Central Corneal Thickness measurement, when compared with controls. In view of the above observation and reduction in Corneal Thickness measurement, the present study indicates generalised corneal changes in Rhegmatogenous retinal detachment unrelated to intraocular pressure.
