A Retrospective Cohort Study of Major Salivary Gland Tuberculosis: Our 13 Year Experience.

The tuberculous infection of major salivary glands is rare because they are relatively resistant to tubercle bacilli. The aim of this study is to present our 13 year experience on major salivary gland tuberculosis. The clinical, histopathological, microbiological and imaging records of 9 cases of major salivary gland tuberculosis were reviewed retrospectively. The cases diagnosed with either microbiological culture and/or polymerase chain reaction assay and/or Histopathological examination were included in the study. Descriptive statistics were used to summarize the data. There were 9 cases with tuberculous involvement of major salivary glands; parotid (n = 5), submandibular (n = 3), sublingual (n = 1). The most common local symptom was painless swelling present in 8 cases and constitutional symptoms were present in all the cases. The previous history of TB was present in 5 out of 9 cases. Surgical intervention was done in 2 cases of parotid TB for diagnostic purpose and therapeutic intervention was required in 1 patient. Patients responded well to medical therapy. Two patients with disseminated disease died. The major salivary gland is rare in both immunocompetent and immunocompromised patients. Diagnosis is difficult and requires high degree of suspicion especially in isolated cases. Medical management yields satisfactory results.

Submandibular Gland Tuberculosis: A Literature Review and Update.

Submandibular salivary gland is an uncommon and unusual site for tuberculosis. It is a rare extrapulmonary manifestation of a common infection caused by Mycobacterium tubercle bacillus. Submandibular gland TB can be due to primary or secondary infection. The clinical features are non-specific and depend on its manifestations. A delay in diagnosis is common because of the rarity of disease. Direct histological examination is the best method of diagnosis. As the disease is curable with antituberculous drugs; treatment should not be withheld in suspected cases until the diagnosis is confirmed. Surgery is indicated for non-responsive disease and complications. Till date, only 15 cases have been reported in the literature. First case was reported in the year 1990. The authors encountered three cases in last 10 years. The aims of this study are to review clinical presentation, epidemiological features, diagnostic methods and to provide our data and guidelines for optimum management of this rare pathology.

Management of pregnant female with Haemophilia-A: A case report.

Haemophilia-A is a rare, X-linked recessive inherited disease affects males and females are carrier results in prolonged bleeding after minor injuries, procedures or surgery. Spontaneous or recurrent bleeding may occur in deep muscles, joints but intracranial haemorrhage can be dangerous. Women with a family history of bleeding disorder, personal history of bleeding (menorrhagia, mucous membrane, postoperative bleeding and PPH) or a prolonged activated partial thromboplastin time (aPTT) should be screened for haemophilia by measuring coagulation factor VIII level during hospital visits for these reason or antenatal care (ANC). Female heterozygote carriers may have variable presentation of bleeding due to reduced levels of clotting FVIII and may experience excessive bleeding due to gynaecologic issues, during spontaneous abortion, medical termination of pregnancy or invasive prenatal diagnostic techniques in first trimester of pregnancy, antepartum and postpartum haemorrhage in later part of gestation and after delivery.

Analysis of cellular and cell free mitochondrial DNA content and reactive oxygen species levels in maternal blood during normal pregnancy: a pilot study.

BACKGROUND: Alterations in mitochondrial signatures such as mitochondrial DNA (mtDNA) content in maternal blood have been linked to pregnancy-related complications. However, changes in maternal mtDNA content, their distribution and associated signaling during normal pregnancies are not clear; which could suggest their physiological role in maternal adaptation to pregnancy related changes and a reference threshold. THE AIM OF THIS STUDY: to assess the distribution of mtDNA in peripheral blood and their association with circulatory ROS levels across different trimesters of healthy pregnancy. METHODS: In this pilot cross sectional study, blood samples of normal pregnant women from each trimester (total = 60) and age-matched non-pregnant (NP) women as control group (n = 20) were analyzed for a) the relative distribution of mtDNA content in cellular and cell free (plasma) fractions using relative quantitative polymerase chain reaction (qPCR) and b) the levels of circulating reactive oxygen species (ROS) by measurement of plasma H2O2. The results were compared between pregnant and NP groups and within trimesters for significant differences, and were also analyzed for their correlation between groups using statistical methods. RESULTS: While, we observed a significant decline in cellular mtDNA; plasma mtDNA was significant increased across all trimesters compared to NP. However, from comparisons within trimesters; only cellular mtDNA content in 3rd trimester was significantly reduced compared to 1st trimester, and plasma mtDNA did not differ significantly among different trimesters. A significantly higher level of plasma H2O2 was also observed during 3rd trimester compared to NP and to 1st trimester. Correlation analysis showed that, while cellular mtDNA content was negatively correlated to plasma mtDNA and to plasma H2O2 levels; plasma mtDNA was positively correlated with plasma H2O2 content. CONCLUSIONS: This study suggested that normal pregnancy is associated with an opposing trend of reduced cellular mtDNA with increased circulatory mtDNA and H2O2 levels, which may contribute to maternal adaptation, required during different stages of pregnancy. Estimation of mtDNA distribution and ROS level in maternal blood could show mitochondrial functionality during normal pregnancy, and could be exploited to identify their prognostic/ diagnostic potential in pregnancy complications.

Pregnancy with Renal Disease: Present Scenario in Tertiary Care Institute in Northern India.

Abstract: Renal disease has always been a challenge for the treating obstetrician. With new advances in the management of renal disease, an increasing number of patients can continue the pregnancy and with individualization have a better outcome. Material and Methods: To analyze the pregnancy outcomes in renal disease, a retrospective cohort observational study over 5 years at a tertiary care institute in northern India was done. All the pregnant women with pre-existing renal disease of any etiology presenting at any period of gestation who consented were included and those not consenting were excluded from the study. Results: Of 62 patients enrolled, 82.26% (n = 51) were followed,17.74%(n = 11) were lost to follow up. 58.82% (n = 30) had to undergo termination of pregnancy and 41.18%(n = 21) had delivery after 28 weeks of gestation. The antenatal complications seen were hypertension in 15.69%, diabetes mellitus in 9.80%, anemia in 5.88%. Fetal complications included preterm delivery (42.85%) and small for gestational age babies(61.90%). Cesarean delivery was 85.71% and normal delivery in 14.29% of patients. Conclusion: Both maternal and fetal outcomes are influenced by the cause and degree of renal dysfunction. A better outcome is seen when the renal disease is under control, good antenatal follow-up, multidisciplinary approach, and timely delivery.

Triage of antenatal care through telehealth during COVID-19 pandemic in a tertiary care centre of North India.

Background: Telemedicine facilitates patient care in various fields including antenatal care. Its application and usefulness need objectification and can be a guide to using this service in the care of pregnant women. Material and Methods: This was a prospective observational study conducted from May 2020 to December 2020. Following the telemedicine practice guideline of the country, 3,360 teleconsultations were sought by 862 antenatal patients. The duration of each call, an indication of referral and pregnancy risk stratification were noted. Further management was classified into three categories depending upon the need for an immediate hospital visit, no hospital visit or scheduled visit after at least 48 h after the first contact. Results: The antenatal cases were referred for either maternal, foetal or both indications in 24.7, 54.8 and 20.5% of the cases, respectively. Women were classified as low risk (61.6%), high risk (35.7%) and severe risk (2.7%). In 1.4% of the patients, history and review of the records could not be done through telemedicine. The average time spent was 16.6 min for the first contact and 3.1 min for subsequent contacts. Further management was done with immediate visits in 385 (45.3%), scheduled hospital visits in 292 (34.3%) women and no tertiary care hospital visit in 173 (20.4%). Discussion: Women (20.4%) not called to the maternal-foetal medicine department of the institute were managed along with the treating obstetrician and no difference in pregnancy outcome was noted. Conclusion: Antenatal care can be provided following triage over teleconsultation and 1.4% of the women may not be able to use telehealth.

Prediction of Low Birth Weight by Quadruple Parameters in High-Risk Pregnancies.

Context: Aneuploidy screening is done in the early second trimester of pregnancy among all pregnant women as compulsory, with a special focus on those who had abnormal ultrasound parameters, higher dual marker risk, or other comorbidities. Recently, all individual quad markers of conventional trisomy screening have been suggested as useful in predicting adverse pregnancy outcomes (APO) such as preeclampsia, preterm labor, small for gestational age, and placental abruptions. However, similar studies on Indian pregnant women are limited. Hence, this study was intended to find the relation of quadruple markers with any other APO than aneuploidy. Materials and Methods: A retrospective study was conducted in a Tertiary Care multi-specialty hospital in North India. Data from 252 pregnant women's quadruple test was analyzed. The association of abnormal value of quadruple markers (human chorionic gonadotropin [HCG]/alpha-fetoprotein/uE3/Inhibin A) with adverse outcomes was evaluated. Multiple logistic regression analysis and classification and regression tree were used to predict the significant risk factor in high-risk pregnancies. Results: In the study, a total (n = 252) of pregnant women, 190 were screened as high-risk pregnancies, whereas the remaining 62 were reported as low-risk using trisomy screening in the quadruple test. Baby birth weight was observed to be significantly associated with Inhibin-A, and HCG (P < 0.001), whereas Corrected (Corr)-multiple of median (MoM)-HCG (>1.415) and Inhibin-A Corr-MoM (>364.175) were the suitable predictor for the LBW. Both parameters were significantly higher in the high-risk group as compared to the low-risk group (each P < 0.05). Conclusion: Abnormal deviation of biochemical markers from aneuploidy screening assessment could help predict other perinatal adverse outcomes such as low birth weight babies.

Outcome of scrub typhus in pregnancy during COVID-19 pandemic: A case report.

Coronavirus disease 2019 (COVID-19) pandemic has emerged as the major public health threat in recent times. Although associated with high morbidity and mortality affecting all age groups across populations, "pregnant women" represent a subgroup that needs extra surveillance. We present the case of a primigravida in her advanced pregnancy presenting with acute febrile illness with flu-like symptoms. The clinico-radiological picture was suspicious for COVID-19; however, she tested negative for COVID-19 on two occasions. On further investigations, she tested positive for Scrub typhus (IgM-ELISA) and responded to treatment with doxycycline. However, due to the ongoing COVID-19 pandemic, much time was lost before suspecting and reaching the final diagnosis. Therefore, the patient had to suffer due to delayed medical intervention and intrauterine fetal death. Despite the unprecedented rise of COVID-19 in pregnant women in recent times, we should not forget about other tropical illnesses, which can mimic COVID-19 in clinical presentation and affect feto-maternal outcomes adversely.

Circulating Placental Alkaline Phosphatase Expressing Exosomes in Maternal Blood Showed Temporal Regulation of Placental Genes.

Background: Analysis of placental genes could unravel maternal-fetal complications. However, inaccessibility to placental tissue during early pregnancy has limited this effort. We tested if exosomes (Exo) released by human placenta in the maternal circulation harbor crucial placental genes. Methods: Placental alkaline phosphate positive exosomes (ExoPLAP) were enriched from maternal blood collected at the following gestational weeks; 6-8th (T1), 12-14th (T2), 20-24th (T3), and 28th-32nd (T4). Nanotracking analysis, electron microscopy, dynamic light scattering, and immunoblotting were used for characterization. We used microarray for transcriptome and quantitative PCR (qPCR) for gene analysis in ExoPLAP. Results: Physical characterization and presence of CD63 and CD9 proteins confirmed the successful ExoPLAP enrichment. Four of the selected 36 placental genes did not amplify in ExoPLAP, while 32 showed regulations (n = 3-8/time point). Most genes in ExoPLAP showed significantly lower expression at T2-T4, relative to T1 (p < 0.05), such as NOS3, TNFSF10, OR5H6, APOL3, and NEDD4L. In contrast, genes, such as ATF6, NEDD1, and IGF2, had significantly higher expression at T2-T4 relative to T1. Unbiased gene profiling by microarray also confirmed expression of above genes in ExoPLAP-transcriptome. In addition, repeated measure ANOVA showed a significant change in the ExoPLAP transcriptome from T2 to T4 (n = 5/time point). Conclusion: Placental alkaline phosphate positive exosomes transcriptome changed with gestational age advancement in healthy women. The transcriptome expressed crucial placental genes involved in early embryonic development, such as actin cytoskeleton organization, appropriate cell positioning, DNA replication, and B-cell regulation for protecting mammalian fetuses from rejection. Thus, ExoPLAP in maternal blood could be a promising source to study the placental genes regulation for non-invasive monitoring of placental health.

To Study the Vitamin D Levels in Infertile Females and Correlation of Vitamin D Deficiency with AMH Levels in Comparison to Fertile Females.

CONTEXT: Human and animal data suggest that low vitamin D (25-hydroxyvitamin D) status is associated with impaired fertility, endometriosis, and polycystic ovary syndrome. Vitamin D regulates antimullerian hormone (AMH), FSH, mRNA, and expression of genes in reproductive tissues, implicating a role in female reproduction. AIMS: To study the vitamin D levels in infertile females and to know the correlation of vitamin D deficiency (VDD) with serum AMH in infertile females compare to fertile females. SETTINGS AND DESIGN: This prospective study was conducted in department of Maternal and Reproductive Health in between April 2014 and April 2016. MATERIALS AND METHODS: After matching inclusion and exclusion criteria out of total 70 infertile females, 45 were found to have VDD. Of these 35 patients were identified as cases; in whom, the AMH levels were assessed. As control 35 fertile normal females were taken, in which vitamin D and AMH were taken. In both groups, correlation of VDD with AMH was studied. STATISTICAL ANALYSIS USED: To analyze the correlation between vitamin D and AMH linear regression test and for comparison of both the groups, two sample t tests were used. RESULTS: The VDD was present in 64.28% of infertile females. In vitamin D deficient cases, the mean for vitamin D was 6.18 ± 2.09 and AMH was 1.94 ± 1.30. In vitamin D deficient controls, the mean for vitamin D was 4.85 ± 3.02 and AMH was 3.47 ± 2.59. On comparison, the vitamin D levels were lower in fertile than infertile females, which was significant (P = 0.04), and AMH levels were lower in cases than control group (P = 0.003). CONCLUSION: The VDD was present in 64.28% of infertile females. No significant correlation was found in between VDD and AMH levels in both the groups.

Jejunal Windsock Deformity: A Rare Cause of Incomplete Neonatal Intestinal Obstruction.

Incomplete intestinal obstruction due to windsock web of the jejunum is uncommonly noticed in neonates. We present a male neonate, prenatally suspected case of proximal bowel obstruction, who was found to have features of incomplete intestinal obstruction due to windsock deformity in jejunum. The difficulty in the diagnosis and management is discussed along with relevant literature review.

Association between lactate levels in vaginal fluid and time of spontaneous onset of labor in suspected cases of prelabor rupture of membranes.

PURPOSE: To assess correlation between lactate levels in vaginal fluid and onset of labor in suspected PROM. METHOD: A prospective observational study conducted at the Dept. of Obstetrics and Gynecology and Pathology from 2008 to 2009. 118 women with complaints of leaking per vaginum underwent a sterile speculum examination and vaginal fluid was taken to estimate lactate level. Then, women were followed till the spontaneous onset of labor. The association was presented as Odds ratio with 95 %CI. RESULTS: The median time of onset of spontaneous labor and examination was 12 h in patients with lactate levels >5.0 mmol/L and 76 h in patients with lactate levels <5.0 mmol/L. Among 62 women with lactate levels >5.0 mmol/L, 67.7 % of women (n = 42) had spontaneous onset of labor within 24 h and 83.87 % women of (n = 52) within 48 h. CONCLUSION: A lactate level >5.0 mmol/L is significantly associated with the spontaneous onset of labor within 24 and 48 h in suspected cases of PROM.

Lactic dehydrogenase: a biochemical marker for preeclampsia-eclampsia.

OBJECTIVES: To correlate the severity of the disease, maternal and perinatal outcome with Lactic Dehydrogenase (LDH) levels in serum in patients of preeclampsia and eclampsia. METHODS: A prospective comparative study was conducted in the department of Obstetrics and Gynecology in the collaboration with department of Pathology, CSM Medical University, Lucknow. Out of 146 women studied, 39 were normal pregnant women, 35 were of mild preeclampsia, 36 of severe preeclampsia and 36 of eclampsia. The statistical analysis was done by Chi-square test (for proportional data) analysis of variance and sample "t" test (for parametric data). RESULTS: LDH levels were significantly elevated in women with preeclampsia and eclampsia (<0.001). Higher LDH levels had significant correlation with high blood pressure (P < 0.10) as well as poor maternal and perinatal outcome. CONCLUSION: High serum LDH levels correlate well with the severity of the disease and poor outcomes in patients of preeclampsia and eclampsia.
