Is HLA-B27 the ankylosing spondylitis susceptibility gene?

We studied a family in which the mother and her son had primary ankylosing spondylitis (AS). The mother carried the HLA-B27 allele, but did not pass this to her son. It is possible that the son is a coincidental, sporadic, non-B27 patient with spondylitis and the presence of B27 in the mother is relevant to the disease. Alternatively, it is possible that B27 in the mother is coincidental and the non-B27 haplotype, inherited by the son, carries the disease susceptibility gene. The results would then support the hypothesis that the B27 antigen may not be the AS gene, but rather a marker for another closely linked AS gene.     

Efficacy and Toxicity Profile of Methotrexate Chloroquine Combination in Treatment of Active Rheumatoid Arthritis

Background

The present study was conducted to study the efficacy and toxicity profile of methotrexate chloroquine combination in treatment of active rheumatoid arthritis.

Methods

24 patients of rheumatoid arthritis confirming to revised American Rheumatism Association (ARA) criteria were studied prospectively for twenty months. Clinical evaluation was made every 3 months. Clinical disease variables measured at each visit were number of joints with swelling, number of joints with tenderness and pain, duration of morning stiffness and physician and patient assessment of disease activity. Blood counts, liver function tests and other adverse effects due to drugs were monitored every 2 months.

Results

10 patients demonstrated more than 50% improvement. 4 patients withdrew from study, 2 because of excessive nausea and vomiting and 2 because of noncompliance. Other side effects noted were hyperpigmentation, photosensitivity, skin rashes, raised transaminases and stomatitis.

Conclusion

Methotrexate chloroquine combination has good efficacy and toxicity profile. Gastrointestinal side effects are most common and usually responsible for the discontinuation of the drugs.Key Words: Rheumatoid arthritis, Methotrexate, Chloroquine, Efficacy, Toxicity     

Cling wrap, an innovative intervention for temperature maintenance and reduction of insensible water loss in very low-birthweight babies nursed under radiant warmers: a randomized, controlled trial

AIM: The value of polythene film ('cling wrap') to improve thermal control and reduce postnatal weight loss in preterm, very low-birthweight babies was investigated. METHODS: Consecutively born babies with birthweights between 750 and 1500 g were stratified by birthweight (<1250 g, 1251-1500 g) and randomised either to the cling wrap (CW) or no cling wrap (NCW) group. The baby bassinette of the RW was covered with cling wrap up to the level of the neck in the CW group for the 1st 7 days. The primary outcome variables were the incidence of hypothermia (axillary temperature < or = 36 degrees C) after initial stabilisation during the first 7 days and cumulative weight loss (percentage of birthweight) at 48 hours of age. RESULTS: Of 51 babies, 26 were randomised to the CW and 25 to the NCW group. None of the babies in the CW group developed hypothermia in the 1st 7 days but 36% in the NCW group (p = 0.001) did. Babies who were hypothermic on admission took less time to reach normal temperature in the CW group. Cumulative weight loss in the 1st 48 hours was 5.0 + 5.6% in the CW group and 8.6 + 7.0% in the NCW group (p = 0.06). CONCLUSION: Use of CW might be a simple method of maintaining temperature in very low-birthweight babies in developing countries.     

Multifocal scrofuloderma with disseminated tuberculosis in a severely malnourished child

Tuberculosis and malnutrition continue to be significant health problems in developing countries. Moderate to severe malnutrition can cause immunosuppression and predispose children to various infections. We report disseminated tuberculosis in a severely malnourished Indian child who presented primarily with cutaneous involvement.     

Effect of fortification with human milk fortifier (HMF) and other fortifying agents on the osmolality of preterm breast milk

This study was conducted to test the effect of fortification with human milk fortifier (HMF), low birth weight (LBW) formula and coconut oil, initially and upon subsequent storage, on the osmolality of preterm breast milk. Milk samples (n = 48) were collected from mothers (n = 25) delivered at 34 pounds weeks and fortified with HMF (Lactodex-HMF), LBW formula (Lactodex-LBW) and edible coconut oil. Osmolality was measured before and after fortification and after 6 hours,.The gestation and birth weight (median) was 31 (range 29-32) weeks and 1198 (range 716-1478) grams. The median (range) postnatal age at testing was 15 days (range 3-60 days). There was a significant increase in osmolality of breast milk (302.3 +/- l.82) after addition of HMF (392.9 +/- 3.01) and LBW formula (390.5 +/- 2.4). There was no change in osmolality with addition of coconut oil (304 +/- 1.6). There was no further change in the osmolality after 6 hours of storage at 4 degrees C.     

Methylation of tumor suppressor gene p16 and prognosis of epithelial ovarian cancer

OBJECTIVE: Methylation of p16 promoter was evaluated in ovarian cancer to determine the role of p16 methylation in ovarian cancer prognosis. METHODS: Two hundred and forty-nine patients with primary epithelial ovarian cancer were selected for the study; these patients were followed for a median of 31 months. Genomic DNA extracted from fresh frozen tumor tissues were treated with sodium bisulfite and were analyzed for p16 methylation using methylation-specific PCR (MSP). Cox regression survival analysis was performed to examine the associations of p16 methylation with progression-free and overall survivals. RESULTS: Of the 249 patients, 100 (40%) were tested positive for p16 promoter methylation. The status of p16 methylation did not change significantly with patient age, disease stage, histological grade, residual tumor size, and debulking results, although p16 methylation seemed to occur more often in patients with advanced diseases or aggressive tumors. Compared to those without p16 methylation, patients with p16 methylation had significantly higher risk for disease progression (P = 0.01). The relative risk for progression was 1.69 (95% CI: 1.12-2.54), and the association remained statistically significant (RR = 1.54, 95% CI: 1.01-2.34) after adjusting for clinical and pathological variables. The risk for death was also higher in methylation positive patients than in methylation negative patients (RR = 1.33, 95% CI: 0.88-2.00), but the difference was not statistically significant. CONCLUSION: The study suggests that promoter methylation in the p16 gene is associated with ovarian cancer progression, and evaluation of p16 methylation may have values in predicting ovarian cancer prognosis.     

Effect of short-term Psychiatric Intervention in Cancer Patients

A total of 50 patients undergoing cancer treatment at Malignant Disease Treatment Centre were included in the present study aimed at evaluating the psychological status of cancer patients. All patients filled a specially designed proforma and the following psychological questionnaires : General Health Questionnaire, Carroll Rating Scale for Depression, State-Trait Anxiety Inventory, PGI General Well-being Scale and Quality of Life Scale. Analysis of the results showed that 22 (44%) of the cancer patients had psychiatric disorders and this number had reduced to 12 (24%) after therapy. The difference was statistically significant. Psychiatric treatment also resulted in a statistically significant reduction in level of depression as measured by Carroll Rating Scale for depression. Short term psychiatric treatment was found to be very useful in treating psychiatric morbidity and depression in cancer patients.Key Words: Cancer, Depression, Psychiatric morbidity
