Depression reduces the recovery rate of the individual and often deteriorates the condition. Knowledge regarding the prevalence of depression after myocardial infarction is necessary for treatment purposes. The present study is aimed to know prevalence and patterns of depression among post myocardial infarction patients.<br /><strong>Materials</strong> <strong>and</strong> <strong>methods</strong>: A cross sectional study was done on 50 patients who suffered from myocardial infarction at tertiary care hospital, Guntur. A socio demographic chart along with Zung’s depression inventory was used to collect the data from the individual patient.<br /><strong>Results</strong>: In our study, sample comprised of 27 (54%) male patients and 23 (46%) female patients. Symptoms for depression was observed 18 (36%) of the patients. Out of 50 patients 16 (32%) were in the group of mild depression and 2 (4%) patients were in the group of moderate depression, according to Zung’s Self Rating Depression Scale.<br /><strong>Conclusion</strong>: Depression is common among post myocardial infarction patients. Identifying the symptoms of depression and proper treatment will help the patient to improve the treatment outcome of Myocardial Infarction. So it will help in overall improvement of their quality of life.<br /><strong></strong></p><p><strong>Keywords</strong>: Depression, Myocardial infarction, Tertiary care hospital, Zung’s Self Rating Depression Scale.</p> Copyright (c) Correlation of hematological and biochemical parameters to severity of disease in acquired immuno deficiency syndrome. 2017-04-07T11:57:36+00:00 G Ramakrishna Venu Gopala Raju S Venkata G Chaitanya <p><strong>Background</strong>: Acquired Immuno Deficiency Syndrome is a recognized emerging disease and rapidly established itself throughout the world.

Due to the increase in life expectancy and sedentary life style, more cases of such fractures are seen in day to day practice. Surgery is almost always the recommended treatment as morbidity and mortality associated with non-operative treatment is very high. Patients always have pre-existing co-morbidities that dictate the ultimate outcome. Our study was aimed at assessing the surgical management of inter trochanteric fractures using proximal femoral nail.<br /><strong>Materials and Methods</strong>: In our study patients who presented to department of orthopaedics, Katuri Medical College between January 2013 and December 2014, with intertrochanteric fractures were included and treated with Proximal Femoral Nail. Total of 82 patients were included in the study. Medically unfit patients and patients not willing for surgery were excluded from the study.<br /><strong>Results</strong>: 82 patients with intertrochanteric fractures with mean age of 68.8years,who underwent proximal femoral nailing between January 2013 and December 2014 were included in the study. Maximum age of the patient was 93 years, minimum age was 28 years. Majority of the patients were between 40-80 years. Of these 82 cases majority of the cases were due to slip &amp; fall, with predominance of right side.52 % of cases were Boyd and Griffin type 2 fractures. Mean duration of hospital stay was 10.4 days. Mean time of full weight bearing was 13.6 weeks. Mean operation time was 40 .8minutes.Less blood loss of average 50.9 ml. Good to excellent results were seen in 91% of cases, with smaller incision, less blood loss, shorter operation time, early mobilisation of patient, decreased hospital stay, better wound healing &amp; lesser postoperative complications.<br /><strong>Conclusion</strong>: From this study we consider all though Proximal Femoral Nail was technically demanding, with proper technique it gives excellent results. Proximal Femoral Nail was a minimally invasive excellent implant for treatment of intertrochanteric fractures.<br /><strong></strong></p><p><strong>Keywords</strong>: Intertrochanteric fracture, Minimally invasive treatment, Proximal Femoral Nail (PFN).</p> Copyright (c) Non absorbable sutures in the urinary bladder resulting in intravesical calculi and recurrent urinary tract infection: a case report 2017-04-07T11:57:42+00:00 S.V. Krishna Rao Ramkishan Gonuguntla <p>We report an unusual case of a bladder stone formed on a “non-absorbable suture” in a woman with history of previous anti-incontinence procedure (colposuspension). After the removal of the bladder stones, a ring shaped prolene suture material encrusted in the bladder stone was unveiled. Based on the literature, most foreign bodies in the bladder are subject to stone formation on the bladder wall, but rarely become encrusted into a stone within the bladder. We suggest that bladder stone formation should be excluded in clinical evaluation of women with recurrent urinary tract infection.</p> Copyright (c) A comparative study between manual small incision cataract surgery and phacoemulsification, in the improvement of visual outcome. 2017-04-07T11:57:43+00:00 MR Chella VR Ande N Konindala <p><strong>Background</strong>: Cataract extraction is the most frequently performed surgical procedure in patients above 60 years of age.

Mpoto Cornel M. Wambura Felix S. Kisanga <p><strong>Background</strong>: Male circumcision (MC) can reduce men’s risk of contracting Sexually Transmitted Infections (STIs) including HIV/AIDS for at least 50% or even as high as 66%. With this regard, WHO and UNAIDS urge international community to scaled-up MC among uncircumcised men especially in HIV hard hit regions. Residents of Makambako mainly the Bena Kinga do not have a circumcision custom.<br /><strong>Objectives</strong>: This study examined acceptability of MC among traditionally non-circumcising males accessing health care in Makambako Hospital, Njombe Region, Tanzania.<br /><strong>Methods</strong>: This was a quantitative descriptive cross-sectional study. Some 118 uncircumcised males were randomly selected to participate. In addition, 9 health care workers (HCW) and 8 community members were purposively recruited to participate in a qualitative survey. Kiswahili semi-structured questionnaires were administered to the uncircumcised males, and Focus Group Discussions (FGDs) were held with both HCWs and Community members.<br /><strong>Results</strong>: About 70 % uncircumcised males indicated that MC is acceptable, while 97% understand the health importance of MC, signifying that MC is gradually gaining acceptance in the study population. Majority (84%) preferred medical circumcisers over traditional ones due to safety procedure. Data from FGD revealed readiness to undergo<br />MC, and both HCW and Community members urged for reduced costs for such services. <strong>Recommendations</strong>: For sustainability of MC scaling–up, health education should be a permanent agenda to reach the uncircumcised individuals in Njombe District.<br /><strong></strong></p><p><strong>KEY WORDS</strong>: Acceptability, sexually transmitted diseases, male circumcision scale-up</p> Copyright (c) Challenges of monitoring reproductive health services: a case study of antenatal clinics in Kinondoni municipality, Dar Es Salaam 2017-04-07T11:57:47+00:00 Achilles Kiwanuka Ezekiel Mbao Achilles Kiwanuka <p><strong>Introduction</strong>: Antenatal Care (ANC) is one of the interventions that have the potential of significantly reducing the maternal mortality rate when properly conducted.<br /><strong>Objectives</strong>: The purpose of this research was to assess the challenges of monitoring and evaluation of reproductive health services using ANC clinics as a case study and identify strategies for addressing the challenges.<br /><strong>Methods</strong>: The study was descriptive cross sectional employing both qualitative and quantitative methods.
