The incidence of post operative pulmonary infection vary according to the definition of post operative complications and the surgical site.
Aim
Main aim is to study the incidence and various risk determinants of postoperative pulmonary complications following elective abdominal surgery.
Methodology
A total of 103 patients who had an elective abdominal surgery were assessed for complications.
Results
Among 103 patients, 24.27% developed postoperative pulmonary complications. More commonly the elderly men, obese, smokers, prolonged surgery time and midline vertical incision were other determinants for developing complications.
Conclusion
Adequate preoperative evaluation of pulmonary functions can reduce pulmonary morbidity in a high risk patient undergoing an elective abdominal surgery.

Introduction
Polycystic ovarian syndrome (PCOS) is one of the common gynaecological condition of diverse etiology 30% of the infertile women have anovulation due to polycystic ovarian disease, 20-30% of them have hyperandrogenemia and hyperprolactenemia1.
Methods
An explorative type of hospital based study of 102 patient, during a 2 year period was done with 75 (73.52%) married women and 27 (26.47%) unmarried women with varied symptomatology.
Results
67.6% were in the age group 21-30 years. Ovulation induction was done in all the infertile group, an ovulation induction rate of 88.40% was achieved and of these 21 (34.42%) conceived, others on follow up. Of the unmarried women, all had menstrual irregularities along with obesity (51.85%) and hirsutism (48.14%), after treatment 66.66% had an improvement in their symptoms, other still on follow up.
Conclusion
This study demonstrates the various presentations either single or in combination and their response to various medical and surgical management. There should be a rational approach to therapy, treatment of polycystic ovarian syndrome should be tailored according to the major symptoms of the patients.

Introduction
Polycystic ovarian syndrome (PCOS) is seen in 5 - 10% of women of the reproductive age, is the most common form of anovulatory infertility.
Evidence prove that these women exhibit a characteristic dyslipidaemia non insulin dependent diabetes and cardiovascular disease in later life, which are the hallmarks of the metabolic syndrome.
Presence of 3 of 5 common cardiovascular risk factors as a criteria, the prevalence of metabolic syndrome in PCOS is very high (43 - 46%).
Primary infertility cases with clinical features of menstrual irregularities, weight gain, hirsutism, acne and galactorrhea with scan picture of polycystic ovaries were considered for diagnosing PCOS cases.
Aim of the Study
Aim is to establish the relation between PCOS and metabolic syndrome.
Material and Methods
Study Design
A prospective, noninterventional case control study was conducted with 60 primary infertility patients, attending the gynaecological department, S.S. Institute of Medical Sciences and Research Centre, Davangere, Karnataka.
Study population
All these patients had clinical features suggestive of PCOS, of these 30 patients with ultrasound findings of polycystic ovaries were taken as cases and the others were age matched contemporary controls.
Age group: 20 - 30 years. Duration of study: 8 months. (Dec. 2009 - July 2010)
Methodology
After a brief history, waist circumference and blood pressure was recorded, then patients were asked to come on overnight fasting for a fasting blood sugar level and lipid profile assessment.
Results
In the present study all the five parameters needed for diagnosing metabolic syndrome were raised in PCOS cases and compared to controls. Values were statistically significant by student's unpaired 't' test.
An incidence of 38% of metabolic syndrome was noted in the PCOS cases studied.
Conclusion
Women with PCOS were strongly associated with metabolic syndrome when compared with the controls.
Obesity, high triglycerides and low high density lipoprotein levels are closely linked to insulin resistance and they are independent predictors of myocardial infarction and cardiovascular disease.
Results strongly indicate the need for comprehensive screening and education program for women of all ages with PCOS. Modification of lifestyle factors such as diet and exercise along with insulin sensitizers and lipid lowering agents can prevent long term health risks.

Introduction
Women have a right to undergo an abortion if she wishes. Medical abortion is legally accepted under the Indian law. Mifepristone and misoprostol combination offers a safe, nonsurgical alternative for pregnancy termination with good success rates.
Aims and Objectives
The purpose of this study was to evaluation of the clinical efficacy of the combination of mifepristone and misoprostol orally for early termination of pregnancy.
Methods
A prospective clinical study conducted during a one year period included 100 healthy pregnant women consenting for a legal abortion with an ammenorrhoea of no more than 63 days.
Results
This method had a success rate of 94%, with an average induction abortion interval between 40-50 hours, one women needed surgical curettage. No serious side effects expect for nausea was noted.
Conclusion
The combination of mifepristone and misoprostol is effective for the termination of early pregnancy in terms of success, tolerance, safety and practicality.

Introduction
Cancer is one of the leading causes of mortality in women, especially in the developing countries, where palliative care is not greatly emphasized.
Objectives
The primary objective is to analyse the various medical, ethical and legal issues faced by terminally ill gynaecological cancer patients. The other objectives being pain assessment, overall health related quality of life, economic issues and to determine preferences regarding decision making and information disclosure to patients.
Methods
A non interventional hospital based cross-sectional survey of 100 terminallly ill patients was conducted over a period of 2 years (March 2007 - April 2009).With an informed consent, the patient is asked to complete a questionaire.
Results-Medical problems
74% of patients had intolerable pain, so deprived of sound sleep. 98% of them suffered from some form of depression. Poor educational status and poverty made these patients highly dependable on family members for financial assistance (64%). Comparatively the more elderly patients experienced an inner fear, as they were neglected or abandoned by the care takers.
Ethical problems
With good doctor-patient relationship, communication about diagnosis and management was established in 50% of cases, but majority of them (81%) were not involved in decision making, which amounts to medical negligence.
Legal problems
None of the patients were aware of their legal rights during the course of their illness

A series of benzimidazole phenylthiocarbamoyl derivatives were synthesized by condensing substituted 2-mercaptobenzimidazole with substituted benzoyl chlorides. These benzimidazole derivatives were evaluated for their antibacterial activity against Gram Positive bacteria Staphylococcus aureus (ATCC 3750) and Gram Negative bacteria Salmonella typhi (NCTC 786), as well as antifungal activity against a fungal strain Candida albicans (ATCC 10231). It was observed that the 5-naphthoxy-6-chloro benzimidazole derivatives having dichloro substitutions on the phenylthiocarbamoyl part of the molecule showed better activity than the rest.Keywords

Impedance spectroscopy is the study of measurement of impedance and phase with respect to frequency of electrical components or material under study. In the present work, an electrical impedance analysis of air-borne ultrasonic transducers is carried out with the help of a dedicated impedance analyzer, AD5933, manufactured by analog devices. It is a sweep type of resonant frequency tracking instrument that helps to detect the exact resonant frequency for ST 40 and SR 40 transmitter and receiver air borne transducers, respective. It is observed that impedance analyser, AD5933 is effective in the resonant tracking of air borne ultrasonic transducer.Keywords
