P Pu ur rp po os se e: : Fentanyl, a synthetic opioid, is a popular choice amongst anesthesiologists in the operating room. Preinduction iv fentanyl bolus is associated with coughing in 28-45% of patients. Coughing due to fentanyl is not always benign and at times may be explosive requiring immediate intervention. We have studied the role of aerosol inhalation of salbutamol, beclomethasone and sodium chromoglycate in preventing fentanyl induced coughing and have compared their efficacy.M Me et th ho od ds s: : Two hundred patients aged 18-60 yr, undergoing elective laparoscopic cholecystectomy were randomized into four groups of 50 each. Group I served as control, while Groups II, III and IV received an aerosol inhalation of salbutamol, beclomethasone or sodium chromoglycate 15 min prior to entering the operating room. Following iv fentanyl (2 µg·kg -1 ) the incidence of cough was recorded and graded as mild (1-2), moderate (3-5) and severe (> 5) depending on the number of coughs observed. Results were analyzed using 'z' and Fischer's Exact test. A P value of # 0.05 was considered significant. R Re es su ul lt ts s: : The incidence of cough was 28% in the control group, 6%, 0% and 4% in the salbutamol, beclomethasone and sodium chromoglycate groups respectively. Occurrence of cough was significantly low (P # 0.05) in the treatment groups, however the difference amongst the groups was not significant (P $ 0.05).
Background-Spontaneous bullous serous retinal detachment (RD) with subretinal exudation complicating idiopathic central serous chorioretinopathy (ICSC) is a rare and infrequently described clinical entity. Clinical observations are described on this variant form in 11 patients, the largest series reported to date. Methods-13 eyes of 11 Indian patients having this entity were followed up clinically and angiographically for 12-24 months (retrospective, longitudinal). None of the patients had any previous history of other diseases nor were they on any medications. Four eyes received laser treatment (group A); nine eyes were not treated (group B).

The natural history of COVID-19 infection in children is still evolving as the pandemic unfolds. Few cases of severe and often fatal COVID-19 have been reported although the infection is mild in the large majority. Children with cancers are recognised as a high risk group for all infections. Since there aren't any definite treatment guidelines established in children with severe COVID, treatment is guided by adult recommendations which too are often not evidence based. We report the case of a 4-year-old girl with severe COVID-19 associated pneumonia who presented to us as febrile neutropenia. The use of convalescent plasma along with steroids and IVIG showed dramatic results in this child and she recovered without the need for any specific treatment. This is highlighted as one of the earliest cases that is reporting the use of convalescent plasma in a child; the first ever in a child with underlying malignancy.
In this article, we have reviewed current literature regarding the regulation of hepatocellular carcinoma (HCC) by the interaction of malignant hepatocytes and their tissue environment through cytokine signaling, here represented by transforming growth factor-beta (TGF-β) signaling. We have discussed responses of TGF-β signaling in transition of hepatic stellate cells to myofibroblasts (MFBs), recruitment of tumor-associated macrophages (TAMs), and enrichment of tumor-associated endothelial cells (TECs). The malignant hepatocytes also secrete various factors such as platelet-derived growth factors (PDGFs), vascular endothelial growth factor (VEGF), and TGF-β. TGF-β, a super-family of cytokines, creates tumor microenvironment by interacting through other growth factors (epidermal growth factor receptor (EGFR), PDGF, fibroblast growth factor (FGF), hepatocyte growth factor (HGF), VEGF), cytokines and chemokines, and extracellular matrix (ECM) remodeling. Hence, the HCC tumor microenvironment may now be recognized as an important participant of tumor progression to act as potential target to systemic therapies compared to targeted therapies.
Nasogastric tube placement can cause ulceration and bleeding from the nose, pharynx, esophagus, and stomach. Its accidental placement into the tracheopulmonary system may lead to pneumothorax, hemothorax, or even death. We report a case of its knotting over the epiglottis, leading to life-threatening respiratory distress.
Rohu is a leading candidate species for freshwater aquaculture in South-East Asia. Unlike common carp the monsoon breeding habit of rohu restricts its seed production beyond season indicating strong genetic control over spawning. Genetic information is limited in this regard. The problem is exacerbated by the lack of genomic-resources. We identified 182 reproduction-related genes previously by Sanger-sequencing which were less to address the issue of seasonal spawning behaviour of this important carp. Therefore, the present work was taken up to generate transcriptome profile by mRNAseq. 16GB, 72bp paired end (PE) data was generated from the pooled-RNA of twelve-tissues from pre-spawning rohu using IlluminaGA-II-platform. There were 64.97 million high-quality reads producing 62,283 contigs and 88,612 numbers of transcripts using velvet and oases programs, respectively. Gene ontology annotation identified 940 reproduction-related genes consisting of 184 mainly associated with reproduction, 223 related to hormone-activity and receptor-binding, 178 receptor-activity and 355 embryonic-development related-proteins. The important reproduction-relevant pathways found in KEGG analysis were GnRH-signaling, oocyte-meiosis, steroid-biosynthesis, steroid-hormone biosynthesis, progesterone-mediated oocyte-maturation, retinol-metabolism, neuroactive-ligand-receptor interaction, neurotrophin-signaling and photo-transduction. Twenty nine simple sequence repeat containing sequences were also found out of which 12 repeat loci were polymorphic with mean expected-&-observed heterozygosity of 0.471 and 0.983 respectively. Quantitative RT-PCR analyses of 13-known and 6-unknown transcripts revealed differences in expression level between preparatory and post-spawning phase. These transcriptomic sequences have significantly increased the genetic-&-genomic resources for reproduction-research in Labeo rohita.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
