Proteus syndrome with huge tonsillar mass causing dysphagia: a rare case.

Proteus syndrome is a rare and highly variable hamartomatous syndrome that can affect multiple organ systems. It is characterized by hyperplasia of connective tissue, vascular malformations, epidermal naevi and hyperostosis. Most of the cases present to plastic and orthopaedic surgeons. Otolaryngologic presentations are minimal. We report such a rare case, which presented with a huge unilateral tonsillar mass causing dysphagia.

A fatal pulmonary infection by Nocardia brasiliensis.

The reported case is of primary pulmonary nocardiosis, caused by Nocardia brasiliensis, in a immunocompromised patient, which ended fatally despite appropriate treatment. The partially acid fast filamentous bacterium was predominant on direct examination of the sputum. It was cultured on blood agar, MacConkey agar and by paraffin baiting technique. The bacterium was resistant to cotrimoxazole, the drug of choice for nocardiosis.

Urogenital myiasis due to Chrysomyia bezziana.

Genitourinary myiasis, associated with ulcerating lesions and poor hygiene of the local site, has been infrequently reported. We report a case of 45 year-old urinary incontinent female suffering from carcinoma cervix, who presented with genitourinary myiasis. The larva was identified as of Chrysomyia bezziana Villeneuve (C. bezziana).

Rare case of Metagonimus yokogawai.

Intestinal Heterophyid infections are almost unknown in India with only one documented case report. We report a case of six year old child with diarrhoea without any other associated gastrointestinal symptoms. Examination of the faeces revealed eggs of Metagonimus yokogawai. However, the patient left against medical advice and was lost to follow up. The case is being reported because of its rarity.

Acute cerebellar ataxia associated with chickenpox.

A case of a child with acute cerebellar ataxia associated with chickenpox virus infection is described. Acute cerebellar ataxia associated with chickenpox is a well-recognised complication and the pertinent features of this condition are discussed.

Embedded sharp metallic spring in esophagus.

Less than 1% of esophageal foreign bodies are irretrievable by endoscopic techniques. These cases require esophagotomy for removal. The impacted metallic spring with sharp ends (in opposite direction) is reported as esophageal foreign body which required esophagotomy after two failed endoscopic removals. The difficulties encountered during endoscopic maneuver, peculiar shape of foreign body and mode of impaction are discussed.

Cholelithoptysis: a rare complication of laparoscopic cholecystectomy.

Two months after laparoscopic cholecystectomy, a 54-year-old man presented for medical care with cholelithoptysis (the coughing up of gallstones). This rare complication was managed without a further operation. Possible mechanisms and preventive measures are discussed.

Effect of centchroman on tubal transport and preimplantation embryonic development in rats.

A single oral administration of centchroman (1.25 mg/kg) to adult female rats within 24 h of mating induced slight acceleration in the rate of transport of embryos through the oviducts. The compound did not seem to produce any deleterious effect on preimplantation embryonic development since well organized and apparently normal embryos were collected from the genital tract up to Day 12 of pregnancy. The recovery rate of embryos from centchroman-treated rats was, however, significantly reduced after Day 4 of pregnancy. There was some stimulation in the rate of cleavage of embryos and morula to blastocyst transformation, but retardation in the shedding of the zona pellucida. The rate of blastocyst formation was not altered when 6-8-cell embryos collected from the oviducts of control rats were transferred to the uteri of control or centchroman-treated females. A delay in zona shedding was observed in the centchroman-treated recipients.

Carbohydrate metabolism in the genital organs of adult female rhesus monkeys: effect of prolonged treatment with centchroman, an antiimplantation agent.

Weekly oral administration of centchroman at 1 and 2.5 mg/kg doses for 3, 6 or 12 months to adult female rhesus monkeys (Macaca mulatta) significantly decreased glycogen content and activity of phosphorylase, glucokinase, lactate dehydrogenase and glucose 6-phosphate dehydrogenase enzymes in all the genital tract tissues. In general, the inhibition was dose and time dependent. No effect was, however, observed in the liver and serum.

Viability and development of 'tube-locked' mouse embryos.

'Tube-locked' morulae and blastocysts were recovered from the ampulla of the oviduct of centchroman-treated mice between Days 4 and 12 post coitum and transferred to the uteri of pseudopregnant female mice. Pregnancy and implantation rates were lower and the post-implantation resorption rate was higher in the treated than in the control group. There was little difference in the pregnancy or implantation rates between embryos recovered on Days 4 or 12 post coitum, but the resorption rate increased with increasing duration of embryos in the oviducts and was 100% for the Day-12 embryos. The resorption rate was similar even when these embryos were transferred to the sterile uterine horn of unilaterally pregnant mice. Centchroman did not produce any deleterious effect on embryos which survived until Day 19 of pregnancy in foster mothers. The average fetal weight was also comparable to those of control fetuses.
