Prevalence, course, and risk factors for executive impairment in patients hospitalized on a general medicine service

The purpose of this study was to determine the prevalence, course, and risk factors for executive impairment in patients hospitalized on a general medicine service. One hundred patients were administered the Executive Interview (EXIT25), the Executive Clock Drawing Task (CLOX), and the Mini-Mental State Examination at admission and discharge. Fifty-two percent of the patients at admission and 56% at discharge had scores indicating impairment on at least one measure of executive function. Median scores on every measure improved during hospitalization. Older patients and those with a cardiac or gastrointestinal disorder were more likely to have executive impairment. The prevalence of executive impairment on general medicine services is high. Although improvement in executive function occurs during hospitalization, many patients remained impaired.     

Effect of forced breathing on ventilatory functions of the lung

Ventilatory functions were studied in 36 male and 35 female subjects (mean age 18.5 years), who underwent six weeks course in forced breathing. Ventilatory functions were studied in the form of Forced Vital Capacity (FVC), Forced Expiratory Volume at the end of one second as % of FVC (FEV1%), Maximum Voluntary Ventilation (MVV), Peak expiratory flow rate (PEFR) and Breath Holding Time. Some of these ventilatory functions were found to be increased after a course of forced breathing.     

Mortality trends in falciparum malaria--effect of gender difference and pregnancy

Falciparum malaria in pregnancy is a significant health problem in India. Pregnant women constitute an important high risk group for malaria infection which may cause abortions, stillbirths, intra-uterine growth retardation (IUGR) and premature labour. In this hospital based study on 602 admitted patients of falciparum malaria which included 314 males, 243 non-pregnant females and 45 pregnant females, there was significantly increased mortality rate in females (18.4%) in comparison to males (7.64%, p < 0.001). The mortality rate was highly significant in pregnant females (37.77%) in comparison to non-pregnant females (14.81%) and males (7.64%; p < 0.001). Severe anaemia with Hb < 5 gm% was observed more commonly in pregnant patients (20.0%) in comparison to non-pregnant patients (4.11%). Incidence of malaria infection was more in primi gravida and second gravida. Pregnancy related complications in the form of preterm live births, intra-uterine death (IUD), still births and abortions were more in primi parous than multiparous patients. As the pregnancy is associated with increased incidence and adverse outcome of P.falciparum malaria infection, chemoprophylaxis should be made an integral part of antenatal care along with antianaemia therapy to reduce the risk of serious maternal and fetal complications.     

Post cardiac injury syndrome--one more cause of false positive IgG, IgM antibodies in pleural fluid against antigen-60 of Mycobacterium tuberculosis

Post cardiac injury syndrome (PCIS) is known to occur following myocardial infarction, cardiac surgery, blunt chest trauma, percutaneous left ventricular puncture and pace-maker implantation. The diagnosis is one of exclusion. We report a case of PCIS following cardiac surgery who showed false positive IgG, IgM antibodies to antigen A60 of Mycobacterium tuberculosis in pleural fluid.
