Pseudomyxoma peritonei is characterized by diffuse collections of gelatinous flux resulting from implantation of malignant tumors or irritation from ruptured benign cysts. We report a patient with pseudomyxoma peritonei caused by an occult primary adenocarcinoma, who had both pleural and hepatic metastases.

Aluminium phosphide is often implicated in accidental and suicidal poisoning in India. Ingestion of even half a fresh tablet invariably results in death, whereas exposed tablets are usually considered harmless. We report two cases of short-segment esophageal strictures that occurred following ingestion of exposed tablet of aluminium phosphide. Both cases could be successfully managed by endoscopic dilatation.

Congenital anomalies of the eye and ocular adnexa occurring in Pondicherry have been described. Anophthalmos, microphthalmos, limbal dermoids, nervus of Ota, anterior lenticonus, buphthalmos, and congenital cataract are very common. Onset of cataract in young individuals was caused by abnormal aminoaciduria. Hereditary factors played a part in 59 percent of the cases who would have become blind if they were not treated. Consanguinity is a major factor in their pathogenesis. Avitaminosis A and systemic infections which are common here may be playing a significant role in their etiology.

Clinical, radiological, and microbiological features of seven cases of osteomyelitis involving the orbital parts of the frontal, the maxillary, and the zygomatic bones are described. The cases were managed with antibiotics, curettage, and sequestrectomy. Problems in the correction of deformities due to circatrization are discussed. It is observed that a skin graft at second stage may be a success.
The purpose of this study was to determine the feasibility, safety and efficacy of elective deployment of a new coil-stent (KR stent) in patients with coronary artery disease. KR stent deployment was attempted in 100 patients (135 lesions) enrolled prospectively at a single centre from December 1996 to March 1997. Ten, 15, 18, 24, and 32 mm long KR stents were manually crimped onto balloons and deployed in native coronary artery lesions. Majority of the patients had recent acute coronary syndromes (unstable angina 30% and post-myocardial infarction angina 56%). Diabetes was present in 34 percent of the patients. Fifty-six percent had single-vessel and 44 percent multi-vessel disease. In 38 percent, the lesions were located in proximal segments and 40 percent of lesions were long. KR stents were successfully deployed in 98 percent of patients. Mean minimal luminal diameter increased by 2.89 +/- 0.63 mm (from 0.57 +/- 0.38 mm before to 3.45 +/- 0.56 mm after the procedure). Mean percent diameter stenosis decreased from 83.33 +/- 10.84 percent before to 3.38 +/- 5.74 percent after the stent deployment. Mean reference vessel diameter was 3.45 +/- 0.56 mm. There were occasional technical complications including balloon rupture (1), stent migration (2) and distal embolisation of atheromatous material (1). One patient developed subacute stent thrombosis. There were no other major in-hospital cardiovascular events. At the end of six-month follow-up, there were no myocardial infarction or death. Six patients presented with recurrence of symptoms within six-months of the procedure, four of whom underwent target vessel revascularisation procedure. In conclusion, the in-hospital and six-month follow-up clinical results were highly encouraging with KR stent. Successful deployment rates were high despite unfavourable clinical and angiographic background. Low clinical events on follow-up will make it suitable for elective stenting.
