Empowering women and health care

Women health workers have made great contributions to the health of their community for many years. In India, women physicians have established some hospitals, e.g., Christian Medical Colleges in Ludhiana and Vellore. Some such hospitals operate in remote areas to serve the poor and the suffering. Women health workers of Jamkhed, Deen Bandhu of Pachod, have proved that village women can improve the health status of their community, particularly that of women and children, if they receive encouragement to learn health care skills In India, community health care lies mainly with women (e.g., nursing personnel and in rural areas). Yet, despite their competence and experience, few become physicians, health project directors, and administrators because the society continues to be patriarchal and discriminates against females. Women need to become empowered to ensure equal opportunities for training and promotion and equal wages for equal work. In Bangladesh, use of bicycles to visit houses allows women paramedical workers from Gonasasthya Kendra, Sawar, freedom and imparts confidence. People must identify customs, practices, laws, attitudes, religious misrepresentations, and policies that discriminate against women and then oppose them. They should set these changes in motion at home, in villages, and from district to national, and even global levels. In India, society blames the mother for having a girl, but the man donates the chromosome determining sex. In Gandhigram, a woman physician and her peers have effected an apparent change in attitude toward the birth of a girl. Now the people confer equal happiness to her birth as they do to a boy's birth. Yet, female infanticides still occur in some villages of Salem District of Tamil Nadu. Sex determination tests often lead to abortion of female fetuses. Once a woman marries she has no right to her maternal home and often suffers from domestic violence. Many people resist legislation to grant women more rights, e.g., property rights. Various media promote women's empowerment.     

Ontogeny of taste sense

Developmental changes in the taste receptors and CNS, in physiological and behavioural patterns in fetus and postnatal animals constitute the ontogeny of taste. Tongue epithelial cells are modified into taste buds only with innervation and are seen to degenerate on denervation. On removal of a portion of the tongue, with its taste buds, the central projections of gustation also atrophy, indicating an interdependence of taste receptors and central areas for their development. Gradual transitions in electrical responses to taste stimuli are shown from fetal to adult stage. While responses to ammonium chloride are marked in early fetus, with advancements in age responses to a wide variety of chemicals are shown. Again, early in the development, fibers responsive to chloride are predominant while at a later stage fibers responsive to sodium increase in number. Behaviourally, human fetus and neonatal mammals showed increased swallowing movements on sweet taste and decreased movements on bitter taste which is somewhat at variance with electrophysiological evidence and reflects on the multimodal involvement of taste cell functional and behavioural dynamics with age.     

Diagnosing "dayans" and "demons"

The new ?Witch Craft Prevention Bill? prohibiting witch hunting was passed in Bihar, India, in reaction to the branding and subsequent killing of more than 500 helpless women as "dayans" (witches) in the past 7 years. Most of them were single, widows, or deserted women victimized by the pathological greed of some of the male members of their families or by some powerful persons in the village community interested in claiming their property. Even with the passage of the bill, though, most of these crimes will remain unpunished because the community is an accomplice in them, and they tend not to be reported. What is needed overall is socioeconomic and political development that will lead to the empowerment of women to ensure that there will be an end to the cruel and inhuman activities (such as witch hunting) instigated by traditional healers or "Ojhas".     

Analgesic effect of environmental noise: a possible stress response in rats

Environmental noise is a known stress, which induces alterations of various physiological responses in individuals exposed to it. Stress has been shown to cause changes in the perception of various sensations including pain and stress-induced analgesia has been observed following exposure to a diverse set of stimuli. To examine the algesic behavior of rats exposed to loud environmental noise, for long duration, we used an environment simulating chamber and conducted the tail flick test for the assessment of pain. The rats were divided into groups and subjected to loud noise for test sessions lasting 1 h, 2 h or 3 h in trials of 5 consecutive days. The noise was of two kinds--a continuous shrill noise (pure tone 92 dB & 98 dB) and an intermittent heavy artillery noise (white noise 102 dB). 15 min before and after each test session, tail flick latencies (TFL) were recorded at 5 min interval. The TFL recorded were normalised to an Index of Analgesia (IA) and the readings statistically analyzed using the F test (ANOVA), the significance being obtained by Tukey's test (at 5% level). The results revealed a significant increase in the TFL and the IA (P < 0.0001) in all the test groups demonstrating a significant analgesic response in rats subjected to noise stress. The analgesia was maximum immediately after noise exposure and declined with time. It was found to be directly related to the duration of exposure, the intensity and the characteristics of the noise with loud intermittent (white) noise and longer duration of exposure producing more analgesia.     

Primary intramedullary spinal cord primitive neuroectodermal tumor with intracranial seeding in an infant

Primary spinal cord primitive neuroectodermal tumor (PNET) is a rare entity. In all, 13 cases have been reported in the literature, including 3 with intracranial seeding. A 3-month-old girl with involvement of the spinal cord below the mid-thoracic level is described. The brain MRI revealed findings indicative of seeding along the intracranial subarachnoid space. Biopsy, duraplasty and removal of laminotomy flap were done. In spite of a good response to the first cycle of postoperative 8-drugs-in-a-day chemotherapy, further treatment was refused. She died 21 days after the onset of leg weakness, which reveals the rapid progression of untreated cases. To our knowledge, this is the first case of spinal cord PNET with parenchymal involvement that has been described in an infant.     

Double β-lactam regimen compared to an aminoglycoside/β-lactam regimen as empiric antibiotic therapy for febrile granulocytopenic cancer patients

In a prospective, randomized trial, 205 febrile episodes in granulocytopenic cancer patients were treated with ceftazidime with or without tobramycin (C±T), both agents being administered only if the initial granulocyte count was below 200/l, or ceftazidime plus piperacillin (C+P). The overall response rate was 71% (39 of 60 for C±T and 45 of 58 for C+P). Logistic regression analyses documented no evidence of a significant difference between the two regimens in overall treatment effect after accounting for the linear effects of potentially important variables, such as infection type and granulocyte count. Although the response rates for the subgroup of patients with bacteremias was better with the C+P regimen (P=0.06), there was no difference in response for patients with bacteremia and profound (<100/gml) sustained granulocytopenia. The double -lactam combination demonstrated in vitro synergism in 73%; antagonism was not seen. Both regimens produced execllent serum bactericidal levels (C±T geometric mean peak 1:170; C+P peak 1:137) against gram-negative but not gram-positive pathogens (1:4; 1:7 respectively) that had caused bacteremia. Emergence of resistance and significant coagulopathy and/or bleeding did not occur during therapy. Antibiotic-related nephrotoxicity was noted in 7 of 95 trials in the C+P and in 6 of 89 trials in the C±T group (P=0.19). The incidence of secondary infections in patients with profound (<100/l) sustained granulocytopenia was lower in the C±T group (P=0.04). Alimentary canal anaerobic flora preservation with C±T, and suppression with C+P, was demonstrated. These results suggest that these regimens are of similar effectiveness and neigher is associated with major toxicity.     

Primary angiitis of CNS : neuropathological study of three autopsied cases with brief review of literature

Primary angiitis of CNS(PACNS) or granulomatous angiitis of CNS is a rare inflammatory disease of small blood vessels mostly confined to the CNS. The clinical and pathological features of 3 autopsied cases are described. Clinically all the three PACNS patients were young males, age ranging from 19 to 31 years. All presented with varied neurological manifestations. There was no evidence of systemic disease in any of the cases. The ESR was normal and CSF analysis showed chronic meningitic pattern. The cerebral angiogram in one case was normal and the CT scan done in another case showed multiple intracerebral haematoma due to vasculitis. Brain biopsy was not done. Diagnosis was made at post-mortem examination. Histology showed characteristic but variable degree of granulomatous and non-granulomatous angiitis of small vessels. Venulitis with parenchymal haemorrhages was the predominant feature and in one case phlebitis with thrombosis was noted. Since the disease responds to steroids and immunosuppressive therapy, establishing antemortem diagnosis is important. In view of the association of angiitis of CNS with bacteria and viral infections, their role in the evolution of the disease needs to be investigated.     

Type 1 diabetic mice are protected from acetaminophen hepatotoxicity.

Streptozotocin (STZ)-induced diabetic (DB) mice challenged with single ordinarily lethal doses of acetaminophen (APAP), carbon tetrachloride (CCl4), or bromobenzene (BB) were resistant to all three hepatotoxicants. Mechanisms of protection against APAP hepatotoxicity were investigated. Plasma alanine aminotransferase, aspartate aminotransferase, and liver histopathology revealed significantly lower hepatic injury in DB mice after APAP administration. HPLC analysis of plasma and urine revealed lower plasma t1/2, increased volume of distribution (Vd), and increased plasma clearance (CLp) of APAP in the DB mice and no difference in APAP-glucuronide, a major metabolite in mice. Interestingly, covalent binding of 14C-labeled APAP to liver target proteins; arylation of APAP to 58, 56, and 44 kDa acetaminophen binding proteins (ABPs); and glutathione (GSH) depletion in the liver did not differ between nondiabetic (non-DB) and DB mice in spite of downregulated hepatic microsomal CYP2E1 and 1A2 proteins in the DB mice, known to be involved in bioactivation of APAP. Compensatory cell division measured via 3H-thymidine pulse labeling and immunohistochemical staining for proliferating cell nuclear antigen (PCNA) indicated earlier onset of S-phase in the DB mice after exposure to APAP. Antimitotic intervention of liver cell division by colchicine (CLC) after administration of APAP led to significantly higher mortality in the DB mice suggesting a pivotal role of liver cell division and tissue repair in the protection afforded by diabetes. In conclusion, the resistance of DB mice against hepatotoxic and lethal effects of APAP appears to be mediated by a combination of enhanced APAP clearance and robust compensatory tissue repair.
