8周基础军训对入伍新兵红细胞及其相关指标的影响

目的探讨8周基础军训(basic military training,BMT)对入伍新兵血像中红细胞及其相关指标的影响,为指导科学的军事训练提供参考。方法数据来自新疆边防部队2015年度入伍的50名男性新兵,分别在BMT前后测定并记录受试新兵的红细胞计数、血红蛋白浓度及血清铁蛋白等。结果经过8周的BMT,新兵血液中血红蛋白浓度、红细胞计数及血清铁蛋白均显著下降(P0.05,P0.01)。结论 8周BMT可能导致入伍新兵发生运动性贫血,铁缺乏可能是其主要原因。

Migration,health, and socioenvironmental safety net among children of Dhaka,Bangladesh

This study quantifies the diarrhea burden among migrant children under age 5 (who have migrated due to environmental degradation) in Dhaka. We used a multifactor socioepidemiological as well as environmental approach with pretested questionnaires and observations. It was found that 52% of the children were affected by diarrhea. Disability-adjusted life years (DALYs) lost was reduced manifold with the increase of mothers' behavioral determinants. Health losses were 1,718 fold with significant coefficient (β) in the migrant group. DALYs lost were significantly associated with socioenvironmental factors such as mother's illiteracy (β = .18; p < .001), no hand wash before eating (β = .08; p = .004), and no hand wash after defecation (β = .10; p < .001). This puts emphasis clearly on the awareness at household level, especially of mothers and children under age 5 in Dhaka, Bangladesh, in formulating migration-related policies.

The biography of Mary E. O'Sullivan: an early American headache specialist

The aim of this study was to review the life of Mary E. O'Sullivan and to summarize her important contributions to the study of migraine. Mary E. O'Sullivan underwent extensive training to become a neurologist at a time when only 5% of women in America were physicians. She published five papers on migraine. In a 1936 Journal of the American Medical Association article, she described a patient with ergotamine overuse headache and recommended that daily doses of oral ergotamine should be avoided. Three years later she described migraine as a 'complex' syndrome with multiple causes and multiple cures. Mary E. O'Sullivan, an ambitious female headache specialist of the 1930s, was an early advocate of the use of ergotamine to treat migraine, yet she was one of the first to report ergotamine overuse headache. Although her life was short, her research, knowledge and ambition at a time when women had limited opportunities in medicine have left a mark.     

Vertical transmission of dengue: first case report from Bangladesh

We report a case of vertical transmission of dengue infection in a new born from Bangladesh. The mother was primigravida with an uneventful antenatal period except the fever she developed at 37 weeks of gestation. She underwent cesarean section for decreased fetal movement. The fever lasted for 7 days and was associated with intense bodyache, and a positive tourniquet test. She did not experience any hemorrhages including from the surgical wound. Her platelet count fell at its lowest to 100,000/mm3. She had bilateral mild pleural effusions and positive anti-dengue antibodies (both IgG and IgM). She received symptomatic treatment. The baby was deeply meconium stained and was resuscitated by a pediatrician. His postnatal period went well until day-3 of life when he developed fever and respiratory distress. There were no signs of meconiun aspiration syndrome (MAS) and the septic work up was negative. The platelets count fell to its lowest of 40,000/mm3 on day-3 and day-5 of his illness. Anti-dengue antibodies (both IgG and IgM) were positive with a nearly four-fold rise of IgM antibodies in the convalescent sera. The boy was treated with platelet transfusions and was discharged on day-6 after becoming ill. This report emphasizes that in a dengue epidemic or when dengue is endemic (which Bangladesh has experienced recently), a pregnant woman with fever, myalgia and/or bleeding manifestations should raise a high suspicion that the baby may develop the disease, and both the mother and baby should be closely followed-up. Viral isolation could not be done due to the unavailability of the test.     

Zinc in CSF of patients with febrile convulsion

OBJECTIVE: This prospective study was carried out from July-December 1999 to see the status of zinc in CSF of children with febrile convulsion and to compare this to that of control. METHODS: Forty-two cases of febrile convulsion and 30 controls (fever without convulsion) were enrolled into the study. CSF zinc was estimated by atomic absorption spectrophotometry (AAS) in Atomic Energy Center, Dhaka and compared between the two groups. RESULTS: The mean zinc level in CSF in the study sample was 40.19mgm/L and that in control was 74.98mgm/L. This difference was statistically significant (p<0.001). CONCLUSION: The study concludes that a significantly lower of zinc exists in CSF of children with febrile. However no relationship was found between CSF zinc status with age, sex, degree & duration of fever and time of lumbar puncture after convulsion.

目的通过对三仙汤促进成骨细胞株增殖的研究,判断三仙汤能否应用于绝经后骨质疏松症的防治。方法应用UMR-106成骨细胞株,采用体外细胞培养技术,以氟化钠为阳性对照药,用MTT法测定三仙汤对成骨细胞增殖的影响。结果氟化钠1.25μmol/L、5μmol/L组与空白组相比有显著性差异(前者P<0.01,后者P<0.001);10μmol/L组与空白组无明显差别。三仙液在5、10、100、500、1000mg/L5个不同浓度均使MTT法检测的光吸收值显著升高(P<0.001或P<0.01)。结论三仙汤能促进体外培养成骨细胞增殖。     

Efficacy of salbutamol by nebulizer versus metered dose inhaler with home-made non-valved spacer in acute exacerbation of childhood asthma

This study was done to evaluate and to compare the efficacy of jet nebulizer and metered dose inhaler (MDI) with home-made non-valved spacer (HM NVS) to deliver aerosolized salbutamol in acute exacerbation of asthma in children. HM NVS was made by 500ml plastic mineral water bottle. It was perforated at the bottom for the insertion of MDI and proximal end was cut for placing the mouth. This prospective randomized study was conducted in the department of Pediatrics, Dhaka Medical College Hospital, during April 2007 to March 2008 with 50 known cases (2-12 years) of bronchial asthma with acute exacerbation. After randomized enrollment, each patient received three doses of salbutamol either through a jet nebulizer or through a HM NVS. Oxygen saturation (SaO2), wheeze, heart rate, respiratory rate were recorded throughout the treatment period. Data were analyzed with SPSS for Windows 10.0 at p value <0.05 was considered significant. The mean age of patients was 59.8 months in nebulizer group versus 69.4 months in MDI with HM NVS group. Baseline clinical characteristics in nebulizer group were SaO2 87.7±2.5 versus 89.0±1.8 percent, RR 59.2±7.3 vs. 63.2±4.8 per minute, HR 155.4±11.8 versus 149.0±10.8 per minute and wheeze in 22(88.0%) cases versus 21(84.0%) cases respectively (p>0.05). After therapy improvement was noted among the nebulizer group (SaO2 87.7±2.5 vs. 94.3±2.8 percent; RR 59.2±7.3 vs. 39.3±4.9 per minute; HR 155.4±11.8 vs. 151.60±17.3 per minute; wheeze 88% vs. 8%) as well as in the MDI with HM NVS group (SaO2 89.0±1.8 vs. 94.8±1.8 percent; RR 63.2±4.8 vs. 38.7±6.4 per minute; HR 149.0±10.8 vs. 144.5±13.5 per minute; wheeze 84% vs. 16%) [p<0.001; CI:95%]. However, these improvements did not differ significantly between the nebulizer group and HM NVS group (SaO2 94.3±2.8 vs. 94.8±1.8 percent, RR 39.3±4.9 vs. 38.7±6.4 per minute, HR 151.60±17.3 vs. 144.5±13.5 per minute and wheeze persisted in 2(8.0%) cases versus 4(16.0%) cases respectively) [p>0.05]. The overall response to these modalities of treatment was satisfactory in nebulizer (19/25) and HM NVS (17/25). Salbutamol delivered through both nebulizer as well as MDI with HM NVS is equally effective in the treatment of acute asthma in children.
