Intracranial pressure monitoring (ICP) is based on the doctrine proposed by Monroe and Kellie centuries ago. With the advancement of technology and science, various invasive and non-invasive modalities of monitoring ICP continue to be developed. An ideal monitor to track ICP should be easy to use, accurate, reliable, reproducible, inexpensive and should not be associated with infection or haemorrhagic complications. Although the transducers connected to the extra ventricular drainage continue to be Gold Standard, its association with the likelihood of infection and haemorrhage have led to the search for alternate noninvasive methods of monitoring ICP. While Camino transducers, Strain gauge micro transducer based ICP monitoring devices and the Spiegelberg ICP monitor are the emerging technology in invasive ICP monitoring, optic nerve sheath diameter measurement, venous opthalmodynamometry, tympanic membrane displacement, tissue resonance analysis, tonometry, acoustoelasticity, distortionproduct oto-acoustic emissions, trans cranial doppler, electro encephalogram, near infra-red spectroscopy, pupillometry, anterior fontanelle pressure monitoring, skull elasticity, jugular bulb monitoring, visual evoked response and radiological based assessment of ICP are the non-invasive methods which are assessed against the gold standard. 展开更多

BACKGROUND Laparotomy remains one of the commonest emergency surgical procedures.Early prognostic evaluation would aid in selecting the high-risk patients for an aggressive treatment.Awareness about risks could potentially contribute to the quality of perioperative care and optimum utilization of resources.Portsmouth modification of Physiological and operative severity for the enumeration of mortality and morbidity (P-POSSUM) and the acute physiology and chronic health evaluation Ⅱ(APACHE-Ⅱ) have been the most widely used scoring systems for emergency laparotomies.It is always better to have a single scoring system to predict outcomes and audit healthcare organizations.AIM To compare the ability of APACHE-II and P-POSSUM to predict postoperative morbidity and mortality in patients undergoing emergency laparotomy.METHODS All patients undergoing emergency laparotomy at the Tata Main Hospital,Jamshedpur between December 2013 and November 2014 were included in the study.In this observational study,P-POSSUM and APACHE-Ⅱ scoring were done,and the outcome analysis evaluated with mortality being the primary outcome.RESULTS For P-POSSUM,at a cut off value of 63 to predict mortality using receiver operating characteristics curve analysis,the area under the curve was 0.989;and for APACHE-Ⅱ,at the cut off value of 24,the area under the curve was 0.965.CONCLUSION Because the ability of APACHE-Ⅱ to predict mortality was similar to P-POSSUM and APACHE-Ⅱ does not need scoring for intra-operative findings and histopathology reports,APACHE-Ⅱ can be used pre-operatively to assess the risk in patients undergoing emergency laparotomy.However,for audit purposes,either of the two scoring systems can be used. 展开更多

Background: Men who have sex with men (MSM) contribute substantially to HIV prevalence in India. The targeted intervention (TI) program is the most important link between MSM and the public health system. Hence, we studied the demographic and sexual behavior characteristics of MSM registered in TI program in India. Methods: We used information maintained at TI sites under the program catering exclusively to MSM in India. Demographic characteristics and sexual behavior of MSM over the past two decades were also studied. Risk behaviors included type of partners, alcohol use, sexual acts per week, years of sex work and age at initiation of sex work. Bivariate analysis was carried out to understand the demographic determinants of sexual behavior. Results: In total, data of 6037 MSMs from 14 TI sites were analyzed. Of these 4655 (73.8%) were young adults (<35 years) and 2565 (40.8%) had completed their matriculation. More than half (55.4%) were married. Double-decker was identified as the most common sub-typology among MSM. Average age of initiation of sex was 23.0 years and average number of sexual acts per week was 6.8 (95% CI: 6.8 - 7.0). Irregular partners and alcohol use were observed in 30.5% and 52.8% of MSM respectively. Cohort analysis revealed a statistically significant declining trend in average age of initiation of sex over the past two decades. The sexual behavior of MSM varied significantly by employment status, education, marital status, state of residence, alcohol use and type of sex partner. Conclusion: MSMs registered with the TI program in India were mostly young, educated, and employed. Many MSM also had a history of heterosexual relationships, and thus had the potential of transmitting HIV infection to the otherwise low risk general population. This analysis supports the use of TI program data for understanding the demographic and sexual behavior characteristics of hard to reach and stigmatized population in society. 展开更多

Introduction: There are a multitude of factors that impact the transmission of HIV from parent to child and the subsequent survival of infected children. Changing dynamics in HIV transmission have led to an increase in the number of children living with HIV in India. This review synthesizes the evidence related to transmission of HIV to children, survival and treatment provision among children living with HIV. Methods: A systematic search was conducted in MEDLINE, IndMed, Web of Science, Google Scholar and major journals related to HIV/AIDS to identify relevant studies published between 1992 and 2015. Inclusion criteria included studies related to parent to child transmission of HIV, treatment of children living with HIV and survival of children living with HIV. One of the authors reviewed the studies and extracted the data in a pre-coded extraction sheet. Results: Thirty-three studies were included in the review. HIV transmission rate from parent to Child who received nevirapine prophylaxis ranged from 2.1% to 27.3%. Extended dose regimen of nevirapine prophylaxis was found to be more effective than the single dose regimen. Adherence to ART ranged from 65% to 95%. Adherence varied depending upon the level of health care facility. Both social and medical factors were associated with non-adherence. CD 4 count at the time of diagnosis and delayed age at HIV diagnosis were important predictors of survival. Conclusion: Shift in policy to provide option B regimen is yielding better results. If the age at diagnosis could be reduced further, it would increase the survival of children living with HIV. The program needs to increase access to the health care facilities. 展开更多
