Standard precautions: Awareness, practice, and adherence among obstetrics and gynecology resident doctors of a tertiary care hospital

Background: Infection control occupies a unique position in the field of patient safety since it is universally relevant to health care workers and patients at every single health-care encounter. Most of the healthcare-associated infections are preventable. Through this study, the awareness, practices, and adherence to standard precautions among the resident doctors were sought. Objectives: The objectives of this study were as follows: (1) To determine the level of awareness, practices, and adherence to standard precautions for infection control among resident doctors and (2) to determine factors affecting infection control. Materials and Methods: After obtaining permission from the Institutional Ethics Committee, an observational study was conducted among the resident doctors in the post-natal care ward (PNC) of a tertiary care hospital. Data collection was done using direct observations, a structured validated interview schedule, and discussions with 21 resident doctors working in the PNC. Results: About 71% of the study population had received a training in standard precautions. Specific infection control protocol as suggested in standard precautions was followed for infection control by 76% of the population. Hepatitis B vaccination coverage with three doses of the vaccine is only 66.6% in the study population. Good awareness in standard precautions considering all five elements together was seen in 57% of respondents. Good practice of standard precautions was seen in 52% of doctors. When the individual elements were considered separately, good practice was seen the least for waste disposal. Most respondents had good practice in hand hygiene and cough hygiene. Conclusion: Deficient adherence to standard precautions among health-care providers warrants new induction and monitoring strategies.

Oral metronomic scheduling of anticancer therapy-based treatment compared to existing standard of care in locally advanced oral squamous cell cancers: A matched-pair analysis.

CONTEXT: Head and neck cancers in developing countries present with advanced disease, compounded by poor access to tertiary care centers. AIM: We evaluated oral metronomic scheduling of anticancer therapy (MSAT) in advanced operable oral cancers, in conjunction with standard therapy. SETTINGS AND DESIGN: This was a retrospective matched‑pair analysis carried out in a tertiary referral cancer center. MATERIALS AND METHODS: Advanced operable oral cancer patients having a waiting period for surgery > 3 weeks were administered MSAT. Patients then underwent standard therapy (surgery +/‑ adjuvant radiation/chemoradiation) as warranted by the disease, followed by MSAT maintenance therapy. Outcomes of the MSAT group were compared with stage‑matched controls with similar waiting periods. STATISTICAL ANALYSIS: Survivals were found using the Kaplan‑Meier method and compared between groups using the log rank test. RESULTS: Response was seen in 75% of 32 patients. Two‑year disease‑free survivals (DFS) in MSAT and control groups were 86.5 and 71.6%, respectively. Two‑year DFS in MSAT group who received at least three months of MSAT was 94.6% (P = 0.03). CONCLUSIONS: Oral MSAT is an economical, effective, and safe adjuvant therapy for oral cancers. It has the potential for preventing progression of the disease and improving DFS.

Growth inhibition of struvite crystals by the aqueous root extract of Rotula aquatica.

Formation of urinary stone is a serious and debilitating problem throughout the world. In the present study, the inhibitory effect of aqueous extract of root of Rotula aquatica was investigated against struvite crystals (one of the components of urinary stone) grown in vitro using single diffusion gel growth technique. For setting the gel, sodium metasilicate solution (specific gravity 1.05) and 0.5 M aqueous solution of ammonium dihydrogen phosphate were mixed, so that the pH of the mixture could be set at 7.0. Equal amounts of supernatant solution of magnesium acetate (1.0 M) prepared with 0.0%, 0.5% and 1% concentrations of the extract were gently poured on the set gels. It was observed that the number, dimension, total mass, total volume, growth rate and depth of growth of struvite crystals decreased with the increasing extract concentrations in the supernatant solutions. The enhancement of dissolution rate and fragmentation of struvite crystals suggested potential application of the extract for inhibition of struvite type urinary stone.

Early detection of precursors of cervical cancer with cervical cytology and visual inspection of cervix with acetic Acid.

A hospital-based, prospective study was done in 350 women of 20-50 years to compare VIA with Pap smear for early detection of cervical dysplasia at Maternity Hospital, Thapathali, from May 2004 to December 2004. Pap smear was taken from each woman followed by VIA. Women with positive VIA and/or positive Pap smear were referred for colposcopy-directed cervical biopsy. The variables studied were age group, presenting complaint, age of marriage, parity, smoking habit and appearance of cervix. The incidence of positive VIA and Pap smear was 2.86 and 0.57 respectively. Pelvic pain was the most common presenting complaint. The majority of the women were married before 20 years of age. All women with either positive VIA and/or Pap smear were of parity two or above. There was no significant association between smoking and positive VIA (P=0.699) or Pap smear (P=0.397). Approximately 36.57% of the women screened had abnormal looking cervix. There were two women with high grade intraepithelial lesion (HSIL) and both were VIA positive and this was statistically significant (Fischer exact P=0.0007). Of the ten VIA positive women, on histopathological examination six showed chronic cervicitis, one acute cervicitis, one showed cervical intraepithelial neoplasia (CIN) II, one had normal finding and one was lost to follow up. VIA as a screening test for cervical neoplasia did not miss any lesion detected by Pap smear and confirmed by cervical biopsy.

Acquaintance with the actuality: community diagnosis programme of Kathmandu Medical College at Gundu village, Bhaktapur, Nepal.

INTRODUCTION: In Nepal, various field programs such as community diagnosis programmes (CDP) have been initiated to make the education of doctors, nurses and dentists more community oriented and relevant and suited to the health care scenario. Community diagnosis refers to the identification and quantification of the health problems in a community and identification of their correlates for the purpose of defining those individuals or groups at risk or those in need of health care. The article presents the main activities of community diagnosis as a core component of community-based education for the medical students at Kathmandu Medical College, Kathmandu, Nepal. METHODOLOGY: A 4 weeks' Community Diagnosis Programme was conducted by MBBS II students (9th Batch) of the Kathmandu Medical College under the supervision of the Department of Community Medicine in November 2006 in the rural community of Gundu VDC (village development committee). The tools used included pre-tested questionnaires, weighing machines, measuring tapes, stethoscopes and sphygmomanometers. After the data collection and compilation, the students presented their findings in oral presentations, accompanied by a written report, including essential recommendations for improving the health status of these communities. RESULTS: The students benefited from the necessary process of integrating clinical skills and a public health approach, so as to enhance their epidemiological thinking and be of greater use to the communities where they will practice. The community also benefited by achievement of behavioral changes leading to healthier lifestyles and increased awareness of health-related matters and their role in quality of life. CONCLUSIONS: CDP is a way to practically demonstrate that the link between a medical college and society is possible. That is, a medical college can serve the community and thus society, with specific activities to improve health and the skills of students who will serve as future health professionals.

Exploring the iceberg of hypertension: a community based study in an eastern Nepal town.

OBJECTIVES: Hypertension is an important public health challenge in the developing and the developed world alike. However, community-based studies on cardiovascular diseases including hypertension in a developing country like Nepal have been limited. The primary aim of this study is to measure the prevalence of hypertension in the Dharan town of Eastern Nepal and to explore the 'iceberg phenomenon' of hypertension in the study population. METHODS: A population-based cross-sectional analytical study was undertaken in the Dharan municipality in 2004-5 with one thousand males aged 35 years and above as participants. The subjects were recruited by simple random sampling of the households in each ward. RESULTS: The overall prevalence of hypertension in the study population was 22.7% which was comparable to the studies from Northern and Western India. The comparison between the population with normal and high blood pressure at time of study shows significant differences in terms of age, religion, current job status, occupation, socio-economic status, physical activity and tobacco use. CONCLUSION: The study shows that while a vast majority of the hypertensive population was not aware of their high blood pressure status, at the same time, a large fraction of the population with increased blood pressure did not have their blood pressure under control. A surveillance system to detect population with high blood pressure, follow up the detected cases of hypertension, as well as motivate and/or counsel the 'hard-to-treat' cases for regular follow-up should be valuable.

Plasma levels of genistein following a single dose of soy extract capsule in Indian women.

BACKGROUND & OBJECTIVE: Soy isoflavones are being used as therapy for menopausal syndrome in many countries. Marketed preparations show variability in bioavailability and there are variations in kinetics due to ethnicity and diet. Inspite of soy isoflavone being available in the Indian market there are no studies to show whether the preparation is likely to be effective in women. This study was carried out to determine circulating levels of genistein, a bioactive soy isoflavone, in Indian women after a single dose of soy extract. METHODS: Six healthy vegetarian women volunteers, between 36 and 62 yr and with a mean body mass index (BMI) 25.01+/-2.02 (kg/m2), were enrolled after an informed consent. Women with antibiotic or Soy food intake within 1 month of study were excluded. A single dose of standardized soy extract capsule containing 64.12 mg of total isoflavones (genistein content equivalent to 31.76 mg) was ingested under supervised fasting condition and multiple blood samples were collected at 0, 1, 2, 4, 6, 8 and 24 h. Genistein levels were measured by high performance liquid chromatography (HPLC) method with a detection level of 2.5 ng/100 microl of injection volume. The intra- and inter-assay coefficients of variation were < 5.32 per cent. RESULTS: Genistein was detected (10.3 to 16.2 ng/ml) in 3 volunteers in baseline samples. Within one hour genistein levels rose from 42 ng to 215 ng/ml with a maximum concentration of 117 to 380 ng/ml at 4 to 8 h. A secondary peak suggestive of enterohepatic circulation was seen between 4 and 6 h in 2 out of 6 volunteers. The mean Cmax was 315.5 +/- 57.1 ng/ml. All women had detectable levels from 25.2 to 109.3 ng/ml at 24 h. INTERPRETATION & CONCLUSION: Our study showed adequate circulating levels of genistein in Indian vegetarian women after a single dose of soy extract. Variability in plasma levels of the soy isoflavones may explain differences in responses to therapy.

Hyperhomocysteinemia as a cardiovascular risk factor in Indian women: determinants and directionality.

OBJECTIVE: To assess Homocysteine (Hcy), vitamin B12 and folic acid (FA) concentrations in resident Indian women and to study their correlation with traditional risk factors for coronary artery disease. MATERIAL AND METHODS: The study included 137 consecutive women who attended a health care program (HCP) for women at and above 40 years of age (MAITREYI's HCP). Fasting blood samples for Hcy, B12 and folate were collected on ice, centrifuged within 1/2 hour and stored at -70 degrees C till assayed using a chemiluminescence method. All women underwent a screening for their general health profile including cardiovascular health. RESULTS: Of the 137 women screened 21 were excluded because of presence of factors known to affect Hcy levels (history of existing CAD had hypothyroidism or were on multivitamin supplements). The median Hcy, folic acid and vitamin B12 levels were 9 pmol/L (range 4.2-38.6), 8.8 ng/ml (2.3-31.6 range) and 214 pg/ml (100-2400 range) respectively. The prevalence of hyperhomocysteinemia (>15 pmol/L) was 24.2%. Correlation for continuous variables using spearman's test and for categorical variables with chi-square test showed a highly significant negative correlation with vitamin B12 (p < 0.001) and FA (p<0.002). Both systolic (p < 0.05) and diastolic (p < 0.02) and diastolic blood pressure also showed a significant correlation. However, no correlation was found between plasma Hcy and blood sugars, lipids, age, body mass index and menopausal status. The CAD risk was assessed using Framingham risk scores and this too did not show a correlation with plasma Hcy. CONCLUSIONS: A large number of women from the present study had hyperhomocysteinemia and were deficient in vitamin B12. A significant negative correlation between vitamin B12 and plasma Hcy levels was foundin these older women. Most Indian studies including the present one do not show a positive correlation between elevated Hcy levels and CAD in spite of a large percentage of persons showing elevated homocysteine levels. Since high Hcy levels are recognized as an independent risk factor for CAD, these findings of absence of correlation between Hcy and CAD as reported in various Indian studies need to be explored and explained.

Association of obesity and physical activity in adult males of Dharan, Nepal.

OBJECTIVES: Obesity is one of the most apparent-yet most neglected public health problems. Physical activity is a crucial element in the development of obesity but still its importance in the occurrence of obesity varies in different populations. This paper aims to study the burden of obesity and its association with physical activity was carried out in a rapidly urbanizing town. METHODS: A cross-sectional study to investigate the prevalence of obesity and its association with physical activity was carried out in one thousand adult males of Dharan municipality. Tools of data collection included interview and physical measurements such as blood pressure, height and weight measurements, and waist and hip circumferences. Odds ratios (ORs) and their 95% confidence intervals for obesity were computed across various demographic and other variables without adjusting and then adjusting for physical activity. RESULTS: The prevalence of overweight and obesity in the population was 32.9% and 7.2% respectively. The study showed that physical inactivity is more importantly associated with obesity in the older population. The trend of young being more obese is reversed after adjusting for physical activity so that those in the older age were more obese than the younger ones. Similarly, those in to the business, vocational and clerical works, those who were more literate and those in the higher socio-economic status were significantly associated with obesity even after correcting for physical activity. CONCLUSION: The prevalence of overweight and obesity is high in the males of Dharan. The value and effect of physical activity seem to vary across different age-groups and socio-economic status and occupations. The young, the technical persons or businessmen and the more prosperous ones probably need to bring down their calorie intake along with emphasis on physical activity in order to bring down their weight and cardiovascular risk.

An imaging study of body composition including lipodeposition pattern in a patient of familial partial lipodystrophy (Dunnigan type).

Familial Partial Lipodystrophy, Dunnigan type (FPLD), is characterised by loss of subcutaneous fat from the limbs and an excessive accumulation of fat on the neck, shoulder girdle and face. Affected individuals have insulin resistance, dyslipidaemia and early cardiovascular events. Body composition (BC) with details of adipose tissue distribution were studied by Dual-Energy X-ray Absorptiometry (DEXA) and Magnetic Resonance Imaging (MRI) ina heterozygote for the FPLD mutation LMNA R482W, and in an age, sex and body mass index (BMI) matched normal control. DEXA revealed a marked decrease in total as well as regional fat percentage in the patient compared to a normal control. Marked reductions in subcutaneous fat in the extremities with substantial lipodeposition in the nape of the neck were confirmed with. MRI. The importance of increased perinephric, retroperitoneal and intermuscular fat in the thighs found in this patient, needs to be explored vis-à-vis the pathogenesis of insulin resistance found in FPLD.

Comparison of Pap test among high and non-high risk female.

A prospective study of pap smear in 100 high risk and equal number of non high risk female among total 1022 female Gynecological patients within a period of two and half months {Beginning of Sept. to middle of Nov. 1995} in Maternity Hospital, Thapathali is presented. There were 9 cases positive for dyskaryosis among high risk and 3 cases among the comparison group. All positive cases were at the age of 35 years and above. In 9 positive cases, 5 cases were in CIN I (55.55%) while 4 were in CIN II (44.44%). Similarly out of 3 positive cases in comparison group 1 was in CIN I category (33.33%) and 2 cases were in CIN II (66.66%). Relation of positive cases with low social class revealed 80% CIN I and 50% CIN II among high risk group where as 66.6% CIN II in comparison group. Analysis of risk factor in development of various grades Dyskaryosis revealed 60% of CIN I had high parity while 50% had CIN II. There are about 40% of CIN I and 75% CIN II among child birth less than 19yrs, 60% smoker had CIN I where as 100%. Smoker had CIN II. 80% of CIN I gave history of excessive vaginal discharge where as 50% of CIN II had excessive vaginal discharge. 40% of CIN I was having injection Depo provera. Cases were also analyzed according to risk factor. Out of 9 positive cases among high-risk females 5 positive had parity more than 4 and 4 cases had less than 4. 5 positive cases were among less than 19 years of first childbirth, 4 among more than 19 years. 7 positive cases were smoker and 2 positive cases were non-smoker. 6 positive cases gave history of abnormal vaginal discharge and 3 positive cases had no abnormal vaginal discharge. Out of 9 positive cases 2 had history of injection Depo provera continuously for more than 5 years where as 7 were non users.

Clinical, endocrine and metabolic studies in the kindred of familial partial lipodystrophy--a syndrome of insulin resistance.

OBJECTIVE: To study clinical, endocrine and metabolic profiles in the kindred of subjects with familial partial lipodystrophy (FPLD, Dunnigan type). MATERIAL AND METHODS: Twenty two relatives (10 males, 12 females), from an extended family with FPLD, were assessed for the phenotypic features, impaired glucose tolerance (IGT)/diabetes mellitus (DM), dyslipidemia and the presence of insulin resistance. Plasma glucose and serum lipids were measured using glucose oxidase and standard colorimetric methods. Serum insulin was estimated by radioimmunoassay. RESULTS: The age was 12 to 67 years, two being adolescents. Two of the 20 adults were overweight and eight were underweight; BMI (adults) was 15.5 to 28.5. Features of FPLD were evident among eight out of 12 women. This typical phenotype was not obvious in all 10 male members. Varying degree of Hirsuitism was observed in four of 12 women, acanthosis nigricans in 11 out of 22 members and skin tags were present in only eight of 22; hypertension in six members and diabetes in four. Eleven members had either impaired glucose tolerance (IGT) (n=7), or DM (n=4). Ten of 20 members showed hyperinsulinemic response on oral glucose tolerance test (OGTT). Dyslipidemia was present in 13 family members. CONCLUSION: The majority (2/3rd) of female members showed typical phenotypic features of FPLD, with a clustering of cardiovascular risk factors and insulin resistance syndrome. More than half the men without phenotypic features of FPLD had either IGT/DM, dyslipidemia, hypertension or cardiovascular disease.
