A comparative study of portal vein embolization versus radiation lobectomy with Yttrium-90 micropheres in preparation for liver resection for initially unresectable hepatocellular carcinoma

BackgroundPortal vein embolization before liver resection is considered the therapy of choice for patients with inadequate future liver remnants. The concept of radioembolization with Yttrium-90 to achieve the same goal has limited data.MethodsWe retrospectively compared patients who underwent portal vein embolization and Yttrium-90 lobectomy before resection of hepatocellular carcinoma in patients with chronic liver disease.ResultsSeventy-three patients underwent portal vein embolization and 22 patients underwent Yttrium-90. Forty-seven percent of patients before portal vein embolization required additional procedures for tumor control, and 27% of patients after Yttrium-90 required additional procedure to mainly induce further hypertrophy. Both therapies achieved the goal of future liver remnants >40%, but the degree of hypertrophy was significantly higher in Yttrium-90 patients (63% for Yttrium-90, 36% for portal vein embolization, P < .01). Tumor response was significantly better with Yttrium-90, achieving complete response in 50% of patients. Resectability rate was higher after portal vein embolization (85% for portal vein embolization, 64% for Yttrium-90, P = .03). Tumor progression was the most common reason precluding surgery. Complete tumor control was the reason not to pursue surgery in 18% of patients after Yttrium-90.ConclusionBoth preoperative portal vein embolization and Yttrium-90, increases liver resectability rates by inducing hypertrophy of future liver remnants in patients with hepatocellular carcinoma and chronic liver disease. Yttrium-90 lobectomy achieved better tumor control and provided more time to assess therapy response, optimizing the indication for surgery.     

Impact of sociomedical factors on pre-school malnutrition -- an appraisal in an urban setting

The nutritional status of 584 preschool children in an urban slum of Srinagar district was assessed through interviews of mothers conducted in a house-to-house survey, the clinical assessment of child nutritional status, and the anthropometric measurement of the children using accepted standard techniques. The anthropometric measurements of the children were compared to the 50th percentile of the Harvard Standard, while the classification recommended by the Indian Academy of Pediatrics was adopted for the categorization and grading of protein energy malnutrition. 60.45% of the children were malnourished, comprised of 33.22%, 20.89%, and 6.34% of children with grade I, II, and III degrees of malnutrition, respectively. Higher prevalence of malnutrition is associated with higher age, female sex, lower per capita income, higher birth order, and lower parental literacy. Parental literacy status followed by birth order and per capita income were the most important factors associated with preschool child malnutrition.     

Serum immunoglobulin profile in normal Kashmiri adults

Serum levels of the immunoglobulins IgG, IgA and IgM were estimated in 102 apparently healthy Kashmiri adults in the age group of 16-60 years, using single radial immunodiffusion method of Mancini et al. The mean serum levels of IgG, IgA and IgM were observed to be 1289.19 +/- 234.9, 216.18 +/- 50.70 and 118.97 +/- 41.88 respectively. No significant difference in the mean serum levels was observed between the two sexes as such, but IgM showed a significant increase in females in the age group of 16-30 years. IgA showed a significant increase with age, with no such increase in case of IgG and IgM.     

Differential expression of Neu messenger-RNA and protein in hamster-kidney and estrogen-induced kidney tumors

An inverse relationship between the expression of the neu oncogene and estrogen receptors has been observed in breast cancer patients. In this study, we examined neu expression in the estrogen-induced and -dependent hamster kidney tumors, in kidney and in controls to evaluate the usefulness of this animal model far studying the regulation of genes important in hormonal cancer. The expression of neu mRNA was analyzed by Northern analysis and Neu oncoprotein localization by immunocytochemistry. The Neu oncoprotein was detected in several segments of proximal and distal kidney tubules, the loops of Henle and the parietal epithelial cells of Bowman's capsule but not in the tumor. neu mRNA was expressed in renal tissue after estrogen treatment and in untreated controls, but not in kidney tumors. The absence of Neu oncoprotein and mRNA from those cell types that have previously been shown to overexpress estrogen receptors in response to estrogen, suggests that the estrogen receptor and neu genes are interdependent in this tumor system, which may thus be a useful animal model for studying the regulation of neu by estrogens.     

Peripheral giant cell granuloma--a case report

Peripheral giant cell granuloma is a lesion arising mainly from the connective tissue of gingiva or periosteum of alveolar ridge. A case of peripheral giant cell granuloma involving a deciduous molar and the succedaneous tooth is reported. The lesion was large and interfered with occlusion. Surgical excision of the lesion along with the deciduous first molar was done. The underlying permanent first premolar was also involved, and had to be removed. The importance of an adequate salivary flow and maintenance of oral hygiene in the prevention of such lesions is stressed.
