Continuation Therapy After ECT for Delusional Depression: A Naturalistic Study of Prophylactic Treatments and Relapse

The study examines the naturalistic clinical course of 21 patients with delusional depression following their acute response to ECT. Their course is contrasted with that of 31 patients with delusional depression who acutely responded to medication treatment. They were treated for a minimum of 6 months (mean 3.5 years) with various continuation medications. Delusional depression is associated with a high rate of relapse, and some form of continuation therapy is clearly required. Akin to the acute treatment studies of delusional depression, prophylaxis with antidepressants alone is inadequate in preventing relapse in delusional depression patients.     

Application of Microalgal Physiological Response as Biomarker for Evaluating the Toxicity of the Textile Dye Alizarin Red S

Textile dyes are becoming a growing threat to the environment. This report presents the findings of the study on the toxicity of the textile dye Alizarin Red S on two freshwater microalgae. The acute toxicity assay revealed that 96-h EC₅₀ values of Chlorella vulgaris and Spirulina platensis were 29.81 mg/L and 18.94 mg/L respectively. The pigments chlorophyll-a, b and carotenoids in C. vulgaris on 96-h exposure to the dye were 2.91, 3.29 and 3.01 times lower in analogy to control whereas Spirulina platensis showed 2.89and 2.56 fold decrease in chlorophyll-a and carotenoid content than control. After the test period of 96-h with dye, the protein content of C. vulgaris and S. platensis were 2.33 and 1.77 times lower compared to the control. The growth inhibition rate, pigment as well as the protein content declined in compliance with the rise in dye concentration, which anticipate paradigm about the toxic effects of the textile dye.

     

IMPORTANCE OF DONOR SELECTION IN RENAL TRANSPLANTATION

Renal transplantation has become a treatment of choice for patients with end stage renal disease. A successful transplant is the result of a combination of several factors acting synergistically, such as the degree of HLA compatibility between donor and the recipient, pretransplant blood transfusions, the recipient''s state of immunoreactivity and sensitization, immunosuppressive therapy given in post operative period etc. Donor selection appears to be the most critical factor for the long term success of the organ graft. In this brief review, some of the important parameters of donor selection in renal transplantation are highlighted.KEY WORDS: Histocompatibility (HLA) matching, Cross match, Sensitization     

Neuro-otological profile of Episodic Vertigo

Episodic Vertigo Comprises a large group of patients seen in any neurootology unit. A total of 118 subjects were reviewed who attended the neurootology unit. Vertigo of shorter duration was noted in 78 and of longer duration in 40 cases. 51 cases showed bilateral neurosensory deafness, 15 cases had bilateral and another one case had unilateral conductive loss. Spinovestibular tests were abnormal in all cases of vertigo of short duration but only 29 cases showed abnormal reflex in patients with a long duration of illness. Thermal vestibulometry revealed hyporeflexia in 33 cases, directional preponderance in 30 cases and 4 cases showed hyperreflexia 28 cases had peripheral lesions while 81 cases had central lesions. The acute cases showed significant improvement on follow up except cases with abnormality in thermal vestibulometry . The cases with positional nystagmus showed improvement with head and body balance exercises expect in those who received treatment with vestibulosedative and vestibular suppersive drugs. Hearing loss remained the same except in patients with middle ear disorders.     

Multimodality management of a case of primary osteogenic sarcoma of the zygoma

Craniofacial osteogenic sarcomas are rare primary malignant bone tumors and very few cases involving zygomatic bone were reported in literature. We present our experience of multimodality management of a case of primary osteogenic sarcoma of zygoma. Wide radical excision of the tumor including the parotid gland was done followed by three cycles of adjuvant chemotherapy and fifty Gy of external radiotherapy. The patient is disease-free at two years follow-up. Till 1970s, craniofacial osteogenic sarcomas were managed mainly by radical surgery with a high local failure rate. With the advances made in the field of radiotherapy and chemotherapy, multimodality therapy is playing a major role in the treatment of these aggressive tumors with better overall and disease-free survival.     

Effect of aluminium impurities in the generator-produced pertechnetate-99m ion on thyroid scintigrams

Cases of reduced uptake of pertechnetate-99m ion in the thyroid gland due to the presence, in the injected solution, of aluminium species at concentrations higher than 4 g/cm³ are reported. This inconvenience can be avoided either by injecting chromatographically pure pertechnetate-99m ion or by allowing the eluate of high aluminium content to stand for about 4 h.     

Lifestyle, parity, menstrual and reproductive factors and risk of gallbladder cancer.

Together with thyroid cancer, cancer of the gallbladder is the only non-sex hormone-related cancer displaying a female preponderance, with incidence being 3-4 times more common among women. We carried out this study to evaluate the role of menstrual, reproductive and lifestyle factors in gallbladder carcinogenesis. A case-control study involving 64 newly diagnosed cases of gallbladder cancer and 101 cases of cholelithiasis was carried out. A detailed menstrual and reproductive history was illustrated beside detailed lifestyle history, in particular consumption of betel nut, tobacco and alcohol and smoking, odds ratio was calculated. Mean age of the patients with cancer was 51+/-1.2 years while it was 40.9+/-1.2 years for gallstones; 69% of cancer patients and 90% of gallstones patients were females. More than half of the cancer patients (53%) and 43% of the gallstone patients were illiterate. A past history of typhoid was present in 22% of cancer patients and 13% of gallstone patients, while 35% of cancer and 25% of gallstone patients were chewers, 18.1 and 9.9% were smokers, and 10% of cancer and 2% of gallstone patients consumed alcohol. Mean age of menarche was 13.4+/-1.2 years among female patients with cancer while it was 14.0+/-1.4 years for gallstone patients. Higher age at menarche (>13 years, OR 2.48, 95% confidence interval (CI) 1.16-5.3), higher number of childbirths(>3 births, OR 3.92; 95% CI 1.4-10.3), higher number of pregnancies (>3 pregnancies, OR 6.66, 95% CI 1.8-23.4), and higher age at last childbirth (>25 years, OR 2.97, 95% CI 1.04-8.5) were found to have significantly higher risk of developing gallbladder cancer. In conclusion, tobacco chewing and smoking are associated with increased odds of gallbladder cancer. Similarly early menarche, late menopause, multiple pregnancies and childbirth increased the risk of gallbladder cancer.     

Proteus syndrome

Abstract: This female Asian (Malay) baby had clinical features of Proteus syndrome. She had a large right facial lipolymphangioma with hyperpigmentation of the overlying skin. There was a smaller lymphangioma over the left side of her neck with excess nuchal folds, macrodactyly and bilateral talipes equinovarus. Despite the extensive hemifacial swelling, there was no evidence of upper respiratory tract obstruction. Generalized seizures developed on the sixth day of life which were controlled with phenobarbital. The lymphangiomas were excised without recurrence.
