Risk factors for preterm birth and low birth weight among pregnant Indian women: A hospital-based prospective study

Objectives: The present study was undertaken to study the maternal risk factors for preterm birth (PTB) and low birth weight (LBW) with a special emphasis on assessing the proportions of maternal genitourinary and periodontal infections among Indian women and their association with adverse pregnancy outcomes. Methods: A hospital-based prospective study comprising 790 pregnant women visiting the obstetrics clinic for a routine antenatal check-up was undertaken. Once recruited, all study participants underwent clinical and microbiological investigations for genitourinary infections followed by a dental check-up for the presence of periodontitis. The study participants were followed up until their delivery to record the pregnancy outcomes. Infectious and non-infectious risk factors for PTB and LBW were assessed using univariate and multivariate Cox regression analysis. Independent risk factors for PTB and LBW were reported in terms of adjusted relative risk (ARR) with the 95% confidence interval (CI). Results: Rates of PTB and LBW in the study population were 7.6% and 11.4%, respectively. Previous preterm delivery (ARR, 5.37; 95% CI, 1.5 to 19.1), periodontitis (ARR, 2.39; 95% CI, 1.1 to 4.9), Oligohydramnios (ARR, 5.23; 95% CI, 2.4 to 11.5), presence of Nugent’s intermediate vaginal flora (ARR, 2.75; 95% CI, 1.4 to 5.1), gestational diabetes mellitus (ARR, 2.91; 95% CI, 1.0 to 8.3), and maternal height <1.50 m (ARR, 2.21; 95% CI, 1.1 to 4.1) were risk factors for PTB, while periodontitis (ARR, 3.38; 95% CI, 1.6 to 6.9), gestational hypertension (ARR, 3.70; 95% CI, 1.3 to 10.8), maternal height <1.50 m (ARR, 2.66; 95% CI, 1.3 to 5.1) and genital infection during later stages of pregnancy (ARR, 2.79; 95% CI, 1.2 to 6.1) were independent risk factors for LBW. Conclusions: Our study findings underscore the need to consider screening for potential genitourinary and periodontal infections during routine antenatal care in developing countries.

Community-based prevalence of genital human papilloma virus (HPV) infection: A systematic review and meta-analysis

Introduction: Cervical cancer probably represents the best-studied human cancer caused by a viral infection and the causal association of this preventable cancer with human papilloma virus (HPV) is well established. Worldwide there is a scarcity of data regarding HPV prevalence with vast differences existing among populations. Objective: The aim of this meta-analysis was to determine the community-based HPV prevalence estimates among asymptomatic women from urban and rural set ups and in participants of cancer screening clinics. Study design: Systematic review and meta-analysis. Methods: PubMed-Medline, CINAHL, Scopus, and Google scholar were systematically searched for studies providing prevalence data for HPV infection among asymptomatic women between 1986 and 2016. Results: The final analysis included 32 studies comprising a population of 224,320 asymptomatic women. The overall pooled HPV prevalence was 11% (95% confidence interval (CI), 9%-12%). The pooled HPV prevalence of 11% (95% CI, 9%-11%) was observed among women attending cervical cancer screening clinics. The pooled HPV prevalences were 10% (95% CI 8%-12%) and 11% (95% CI 4%-18%) from urban and rural areas respectively, indicating higher infection rates among the rural women with the least access to cancer screening and cancer care. Conclusion: The prevalence rates in this systematic quantitative review provide a reliable estimate of the burden of HPV infection among asymptomatic women from developed as well as developing nations. Rural women and women attending cervical cancer screening programmes feature higher genital HPV prevalences compared to their urban counterparts.

Prenatal diagnosis and management of fetal intra-abdominal umbilical vein varix

Fetal intra-abdominal umbilical vein varix (FIUVV) is a rare pathology and suggests an enlargement of the umbilical vein. Prenatal diagnosis is done through meticulous ultrasound imaging. Management variables are the diameter of varix, presence or absence of turbulent flow, and fetal anomalies. Color and power Doppler ultrasound helps in diagnosis and follow-up and has a critical role in decision-making for intervention. Clinical guidelines for management are not clear. The adverse fetal outcome is usually associated with multiple malformations, turbulent flow, and thrombotic varix. This case study presents the prenatal diagnosis, obstetric management, and neonatal development of a fetus, diagnosed with FIUVV along with a brief review of the literature.

Menstrual Disorders from Puberty to Early Adult Age: A Cross-Sectional Survey

Introduction: A female encounters various menstrual disorders from puberty to menopause. We evaluated menstrual disturbances in post-menarche age and young adult age.Aim: To know the prevalence and impact of menstrual abnormalities at early adolescent and young adult age and to evaluate course of disorders identified at early adolescent age.Materials and Methods: A cross-sectional survey was carried out through self-administered questionnaire on 367 consented students at Melaka Manipal Medical College at Manipal, during December 2015- April 2016. Data were analysed by Statistical Package for the Social Sciences (SPSS) 16.0 software.Results: Prevalence and pattern of menstrual disorders at early adolescent and at young adult age were noted. The mean age of menarche was 12.1 ±1.1 years.Menorrhagia was the most frequent (14.7% and 11.7%) and polymenorrhea (7.6 % and 6%) was least frequent menstrual disorder at adolescent age and young adult age respectively. Resolution of pubertal menstrual disorders was observed in all disorders, but noticed highest in oligomenorrhea (91%), (p-value <0.05). Prevalence of menstrual related disorder like dysmenorrhea was 88.7% at adolescent age and 67.6% at the young adult age. It was statistically significant reduction. Hindrance in academic performance and social behavior was noted more at young adult age, which was in 23.9% and 46.7% respectively (p-value <0.05).Conclusion: The most prevalent menstrual abnormality was menorrhagia at the early adolescent and the young adult age. Associated the most prevalent menstrual related symptoms were dysmenorrhea at early adolescent age, and premenstrual symptom at the young adult age. The study demonstrates the natural course (decreasing prevalence) of all menstrual disorders from early adolescent to young adult age.

Hypoparathyroidism in pregnancy

Hypoparathyroidism is an uncommon endocrine deficiency characterised by low serum calcium, absent or inappropriately low parathyroid hormone and normal or high serum phosphorus levels. Parathyroid hormone is essential for calcium homoeostasis. Pregnancy and lactation are known for increased calcium requirement. They cause calcium stress as well as alter its metabolism. Hence, many abnormalities are expected in hypoparathyroidism during pregnancy and lactation. We report a case of pregnancy in postsurgical hypoparathyroidism, which is rarely encountered in antenatal clinics. We describe our clinical, biochemical and therapeutic experience of pregnancy and lactation in this patient with hypoparathyroidism.
