    Notes: Abstract  Esophageal dysmotility is a common occurrence after successful repair of esophageal atresia (EA) and tracheoesophageal fistula (TEF). The etiology of this motility disorder, however, remains controversial. Cine-barium esophagograms were performed in 25 survivors of EA/TEF at a mean age of 30.5 months. A clinical evaluation was done at the same time and the results were classified as “excellent”, “good”, and “fair”. The study revealed that 88% of patients had dysmotile esophageal segments and segmental contractions. Normal peristalsis was seen in only 16% of patients and 64% showed to-and-fro movements. The bolus transit time was delayed in 60%. The clinical status of these patients correlated well with the cine-radiographic findings. Thus, abnormal motility of the esophagus, which may be inherent, exists in postoperative survivors of EA/TEF and may be responsible for the clinical status of these patients.

    Multiple shoot regeneration and tissue culture studies on Bacopa monnieri (L.) Pennell (1999)

    Notes: Abstract  Adventitious shoot buds were induced from leaf and stem explants of Bacopa monnieri on Murashige and Skoog medium supplemented with benzyladenine or kinetin. The source of the explants as well as different gelling agents in the medium were found to influence shoot induction and eventual shoot growth. The best response was obtained in leaf explants taken from shoot cultures grown in medium supplemented with 2 μM benzyladenine and gelled with 0.2% gelrite. A transverse section of the leaf explant incubated in this medium showed several shoot primordia emerging from the leaf surface. This system exhibited a potential for repeated harvesting of the shoots from the original leaf explant as the latter continued to expand and regenerate new shoots, upon repeated periodical subculturing onto fresh medium. However, the callusing response of the plant was very low. Qualitative TLC studies of the regenerated shoots revealed a phytochemical profile similar to that of the field grown-plants.

    Systemic hypertension and aortic obstruction in children (1981)

    Notes: Abstract Congenital coarctation of the aorta and acquired idiopathic obstructive aortitis result in systemic hypertension in children. The incidence of the former disease decreases—and that of the latter condition increases—from Europe to India to Thailand. The clinical profile of coarctation of the aorta as seen in India is similar to that described in the Western literature. Patients with idiopathic obstructive aortitis are generally desperately sick because of cardiac failure or neurological complications. Although it appears to be the result of an inflammatory process, the cause of aortitis is not known. Unless the clinical characteristics of the acute illness are defined investigations are not likely to help in establishing the cause of idiopathic obstructive aortitis.

    Utility of coaxial technique for renal angioplasty in patients with a difficult-to-cross stenosis (1999)

    Notes: Abstract. The aim of this study was to evaluate the feasibility of coaxial approach in difficult-to-cross lesions in patients with failed percutaneous transluminal renal angioplasty by conventional over-the-wire exchange technique. Twelve stenoses in 10 patients (six women and four men; age range 19 ± 7 years) with uncontrolled hypertension were treated by this method. The stenosis was caused by nonspecific aortoarteritis in 8 patients and fibromuscular dysplasia in 2 patients. It was ostial in seven and post-ostial in five vessels. Conventional exchange technique was unsuccessful in all of them. All procedures were done by femoral route. Technical success was seen in 11 (92 %), without complication. The stenosis improved from 90 ± 2.1 % (range 80–100 %) to 6 ± 7 % (range 0–20 %), blood pressure decreased from 198 ± 12.3 mm Hg (range 180–220 mm Hg)/130 ± 6.7 mm Hg (range 120–140 mm Hg) to 119 ± 5.7 mm Hg (range 110–130 mm Hg)/83 ± 3.9 mm Hg (range 80–90 mm Hg), and number of drug treatments for hypertension fell from 3.6 ± 0.52 (range 3–4) to 1 ± 0.94 (range 0–3; p 〈 0.01). Percutaneous transluminal renal angioplasty resulted in “cure” in 3 patients and “improvement” in 7 patients. Follow-up period was 3–21 months (mean 6.4 months). No restenosis was detected. Coaxial approach is safe and effective in treating difficult-to-cross lesions in which renal angioplasty by conventional exchange technique is unsuccessful.
