Uterine Arteriovenous Malformation As A Rare Cause Of Menorrhagia

Uterine arterio venous malformation is uncommon cause of menorrhagia. We report a rare case of arteriovenous malformation diagnosed after 18 years of suffering from menorrhagi

Single-file diffusion and kinetics of template assisted assembly of colloids

We report computer simulation studies of the kinetics of ordering of a two dimensional system of particles on a template with a one dimensional periodic pattern. In equilibrium one obtains a re-entrant liquid-solid-liquid phase transition as the strength of the substrate potential is varied. We show that domains of crystalline order grow as $\sim t^{1/z}$, with $z \sim 4$ with a possible cross-over to $z \sim 2$ at late times. We argue that the $t^{1/4}$ law originates from {\em single-file} motion and annihilation of defect pairs of opposite topological charge along channels created by the template.Comment: 4 pages pdflatex 4 pdf figure

Acquired vaginal stenosis following caesarean delivery: a case report

Postpartum genital tract adhesions are infrequent and their reason has not been appraised. Though, severe dystocia and frequent pelvic examinations have been projected as possible causes. Here, we report a case of vaginal adhesions following caesarean section for obstructed labour that presented as irregular menstruation with desire to remove the PPIUCD. The patient was successfully treated with surgical resection

Genotype-Phenotype Study of the Middle Gangetic Plain in India Shows Association of rs2470102 with Skin Pigmentation

Our understanding of the genetics of skin pigmentation has been largely skewed towards populations of European ancestry, imparting less attention to South Asian populations, who behold huge pigmentation diversity. Here, we investigate skin pigmentation variation in a cohort of 1,167 individuals in the Middle Gangetic Plain of the Indian subcontinent. Our data confirm the association of rs1426654 with skin pigmentation among South Asians, consistent with previous studies, and also show association for rs2470102 single nucleotide polymorphism. Our haplotype analyses further help us delineate the haplotype distribution across social categories and skin color. Taken together, our findings suggest that the social structure defined by the caste system in India has a profound influence on the skin pigmentation patterns of the subcontinent. In particular, social category and associated single nucleotide polymorphisms explain about 32% and 6.4%, respectively, of the total phenotypic variance. Phylogeography of the associated single nucleotide polymorphisms studied across 52 diverse populations of the Indian subcontinent shows wide presence of the derived alleles, although their frequencies vary across populations. Our results show that both polymorphisms (rs1426654 and rs2470102) play an important role in the skin pigmentation diversity of South Asians

Whole-genome sequencing reveals host factors underlying critical COVID-19

Critical COVID-19 is caused by immune-mediated inflammatory lung injury. Host genetic variation influences the development of illness requiring critical care1 or hospitalization2–4 after infection with SARS-CoV-2. The GenOMICC (Genetics of Mortality in Critical Care) study enables the comparison of genomes from individuals who are critically ill with those of population controls to find underlying disease mechanisms. Here we use whole-genome sequencing in 7,491 critically ill individuals compared with 48,400 controls to discover and replicate 23 independent variants that significantly predispose to critical COVID-19. We identify 16 new independent associations, including variants within genes that are involved in interferon signalling (IL10RB and PLSCR1), leucocyte differentiation (BCL11A) and blood-type antigen secretor status (FUT2). Using transcriptome-wide association and colocalization to infer the effect of gene expression on disease severity, we find evidence that implicates multiple genes—including reduced expression of a membrane flippase (ATP11A), and increased expression of a mucin (MUC1)—in critical disease. Mendelian randomization provides evidence in support of causal roles for myeloid cell adhesion molecules (SELE, ICAM5 and CD209) and the coagulation factor F8, all of which are potentially druggable targets. Our results are broadly consistent with a multi-component model of COVID-19 pathophysiology, in which at least two distinct mechanisms can predispose to life-threatening disease: failure to control viral replication; or an enhanced tendency towards pulmonary inflammation and intravascular coagulation. We show that comparison between cases of critical illness and population controls is highly efficient for the detection of therapeutically relevant mechanisms of disease

Expression and regulation of integrin receptors in human trophoblast cells: Role of estradiol and cytokines

748-755<span style="font-size:14.0pt;line-height: 115%;font-family:" times="" new="" roman";mso-fareast-font-family:"times="" roman";="" mso-ansi-language:en-in;mso-fareast-language:en-in;mso-bidi-language:hi"="" lang="EN-IN">Embryo implantation and placentation are dynamic cellular events that require not only synchrony between the maternal environment and the embryo, but also complex cell-cell communication amongst the implanting blastocyst and the receptive endomatrium through integrins, a large family of proteins involved in the attatchment, migration, invasion and control of cellular functions. Integrins display dynamic temporal and spatial patterns of expression by the trophoblast cells during early pregnancy in humans. However, the precise mechanism of embryo implantation and the modulation of the integrin receptors during blastocyst attachment and further implantation remin elusive in the humans. The present study elucidates the expression and hormonal modulation of fibronectin, vitronectin and laminin integrin receptors by estradiol and IL-1α in human trophoblast cells. Human first trimester trophoblast cells showed the induction of the classical estrogen receptor (ER)-α by its own ligand ,estradiol. Treatment with either estradiol or IL- 1α induced the expressions of α4α5α6 and αv, integrin receptor subunits at both the mRNA and protein levels, while expression of β1 remained unaltered. Furthermore estradiol upregulated the expression of IL- 1α, thereby suggesting the possibility that estrogen may either directly or via the proinflammatory cytokine induces the expression of the cell surface integrin receptors. The findings delineate the role of hormones and the cytokines in modulating the adhesiveness and attatchment of the trophoblast cells. This may reflect the in vivo scenario where the implanting embryo is surrounded by a hormone-cytokine rich uterine microenvironment that may preisely regulate the expression of integrins and thereby facilitate implantation.</span

Radiotherapy for iris metastasis from esophageal carcinoma: A series of three cases.

BACKGROUND: Description of three cases of metastatic esophageal carcinoma to the iris and focus on management strategies. METHODS: A 48-year-old man (Case 1) with previously treated stage IV esophageal carcinoma presented with blurred vision in the left eye (OS) for 3 weeks. Initial fine needle aspiration biopsy (FNAB) was negative for malignant cells, so incisional biopsy was performed and confirmed metastatic carcinoma. A 53-year-old man (Case 2) with previously treated stage III esophageal cancer experienced 2 months of pain and 1 month of blurred vision OS. Documented tumor growth suggested esophageal carcinoma metastasis. A 65-year-old man (Case 3) with previously treated stage IV esophageal carcinoma developed hyphema in the right eye (OD), and FNAB confirmed metastatic carcinoma. RESULTS: Case 1 was treated with external beam radiotherapy (EBRT), delivered over 16 days which resulted in complete tumor regression. Case 2 received stereotactic body radiotherapy (SBRT) over 21 days leading to complete tumor regression. Case 3 was treated with plaque radiotherapy over 4 days, resulting in complete tumor regression. CONCLUSIONS: In all three cases, radiotherapy was employed, and enucleation was avoided. Plaque radiotherapy achieved tumor control in a shorter period of time (4 days) compared to EBRT (16 days) or SBRT (21 days). Knowing the short life expectancy of these patients, plaque radiotherapy appears most favorable
