Epithelial atrophy, fibrosis and vascularity correlation with epithelial dysplasia in oral submucous fibrosis, a prospective study. J Microsc Ultrastruct 2022; 10:1-6. [PMID: 35433263 PMCID: PMC9012404 DOI: 10.4103/jmau.jmau_36_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2020] [Revised: 07/13/2020] [Accepted: 07/25/2020] [Indexed: 11/27/2022] Open
Abstract
Background: The pathogenesis of oral submucous fibrosis (OSF) still remains conflicting and has been linked to alterations in epithelial thickness, fibrosis, and vascularity. Although changes in these individual parameters have been extensively studied in relation to epithelial dysplasia their combined relation with dysplasia has not been studied much. Any such relation, if present, may further help in understanding this disease process. Therefore, the aim of this study was to assess the relationship between epithelial thickness, fibrosis, and vascularity with dysplasia in OSF. Materials and Methods: The study consisted of 30 OSF patients. Incisional biopsy was taken from the most fibrosed area of the buccal mucosa. Hematoxylin–Eosin-stained slides were assessed for epithelial thickness, fibrosis, and vascularity using image analysis software. The slides were also assessed for epithelial dysplasia. Relationship of epithelial atrophy, fibrosis, and vascularity with dysplasia was assessed using one-way ANOVA. Pearson's correlation coefficient was used for evaluating the relationship between epithelial thickness, fibrosis, and vascularity. Results: Epithelial dysplasia was found in all patients. Eleven patients had mild (36. 67%), thirteen had moderate (43.33%), and six had severe (20%) dysplasia. None of the parameters were found to have a significant relationship with dysplasia. However, moderate and positive correlation was found between epithelial thickness and fibrosis. This relation was statistically significant. Conclusion: Positive correlation between epithelial thickness and fibrosis in present study therefore contradicts the hypothesis of fibrosis induced epithelial atrophy. As dysplasia is influenced by multiple factors therefore habits and burning sensation needs to be incorporated in future studies assessing dysplasia in OSF.

Abstract
CONTEXT The clinical presentation of histoplasmosis is varied. Due to its propensity for adrenal involvement, histoplasmosis is an important differential diagnosis in any patient presenting with adrenal mass, bilateral in particular. OBJECTIVE Data on clinical presentation, pattern of adrenal involvement, radiological appearance and long-term follow-up of adrenal histoplasmosis are relatively sparse; hence we looked at it. DESIGN This record based single-centre retrospective study was conducted in one of the tertiary care hospitals, situated in eastern India catering the Gangetic delta. SUBJECTS AND METHODS Data on demographic characters, presenting manifestations, biochemical & hormonal parameters and radiological appearance of confirmed adrenal histoplasmosis cases (n=9), admitted between 2015-2019 have been retrieved. The treatment outcome and condition of patients after 1-4 years of follow-up has also been discussed. RESULTS Four out of the nine (44.4%) patients had predisposing immunocompromised conditions in the form of diabetes and/or chronic alcoholism while rest were immunocompetent. Seven out of nine patients (77.8 %) had signs and symptoms suggestive of adrenal insufficiency, while two (22.2%) presented with only pyrexia of unknown origin. All of them had bilateral adrenal mass, though the radiologically appearances were different. All patients received anti-fungal agents with/without hydrocortisone and/or fludrocortisone. One patient died (11.1%), while majority responded favourably to treatment. Adrenocortical function did not recover completely. CONCLUSIONS The possibility of adrenal histoplasmosis should always be considered in patients presenting with bilateral adrenal mass, irrespective of adrenal morphology. Treatment is effective, but many of them require supplemental hydrocortisone for quite a long period, if not lifelong. Mineralocorticoid deficiency, however, is not permanent.

Abstract
Abstract
Aim
To assess whether the timing of post-operative Phosphodiesterase Inhibitor (PDE5i) therapy after Robot Assisted Radical Prostatectomy (RARP) is associated with a change in early erectile function, continence, or safety outcomes.
Method
Data was prospectively collected from a single surgeon in one tertiary centre and retrospectively evaluated. 158 patients were treated with PDE5i therapy post RARP over a two-year period.
Results
There were no significant differences in pre-operative characteristics between the therapy groups. Patients that had bilateral nerve sparing had a mean drop in Erectile Function (EF) score by 5.4 compared to 8.8 in the unilateral group. Additionally, 34.9% of bilateral nerve sparing patients returned to baseline compared to 12.1% of unilateral. Drop in EF scores and percentage return to baseline for unilateral nerve sparing was respectively 9 and 11.1% of immediate (day 1-2), 7 and 14.8% of early (day 3-14) and 9.7 and 9.5% of late (day >14) therapy (p = 0.9 and p = 0.6). For bilateral nerve sparing this was respectively 3.5 and 42.9% immediate therapy, 5.5 and 35.5% early therapy and 7.3 and 25% late therapy (p = 0.017 and p = 0.045). Pad free and social continence was achieved in 54% and 37% of those receiving immediate therapy, 60% and 33% for early therapy and 26% and 54% for late therapy. There were no differences in compliance, complication, or readmission outcomes.
Conclusions
Immediate PDE5i therapy should be considered in patients following nerve sparing RARP in order to maximise functional outcomes, especially in those undergoing bilateral nerve spare.

Abstract
Abstract
Introduction
High costs and inaccessibility are significant barriers to face-to-face basic surgical skills (BSS) training. Virtual classrooms enable the combination of computer-based learning with interactive expert instruction. They may optimise resources and increase accessibility, facilitating larger-scale training with a similar educational benefit. We aim to evaluate the efficacy of virtual BSS classroom training compared to both non-interactive video and face-to-face teaching.
Method
72 medical students will be randomly assigned to three equal intervention groups based on year group and surgical skill confidence. Interventions will be implemented following an instructional video. Group A will practice independently, Group B will receive face-to-face training, and Group C will attend a virtual classroom. Participants will be recorded placing three interrupted sutures with hand tied knots pre- and post-intervention, and Objective Structured Assessment of Technical Skills (OSATS) will be blind marked by two experts. Change in confidence, time to completion and a granular performance score will also be measured. Each intervention’s feasibility and accessibility will be assessed.
Results
Data collection will be completed in January 2021. Significant improvement in OSATS within groups will be indicative of intervention quality. Difference in improvement between groups will determine the relative performance of the interventions.
Conclusions
To our knowledge, this will be the largest randomised control trial investigating virtual BSS classroom training. It will serve as a comprehensive appraisal of the virtual classroom’s suitability as an alternative to face-to-face training. The findings will assist the development and implementation of further resource-efficient training programs during the COVID-19 pandemic and in the future.

Abstract
The etiopathogenesis of COVID-19 and its differential geographic spread suggest some populations are apparently 'less affected' through many host-related factors that involve angiotensin-converting enzyme 2 (ACE2) protein, which is also the entry receptor for SARS-CoV-2. The role of ACE2 has been well studied in COVID-19 but not in the context of malaria and COVID-19. We have previously suggested how malaria might intersect with COVID-19 through ACE2 mutation and here we evaluate the currently available data that could provide a link between the two diseases. Based on the existing global and Indian data on malaria, COVID-19 and the suggested ACE2 mutation, the association could not be examined robustly, neither accepting nor refuting the suggested hypothesis. We strongly recommend targeted evaluation of this hypothesis through carefully designed robust molecular epidemiological studies.

Abstract
Gamma-ray bursts (GRBs), which are bright flashes of gamma rays from extragalactic sources followed by fading afterglow emission, are associated with stellar core collapse events. We report the detection of very-high-energy (VHE) gamma rays from the afterglow of GRB 190829A, between 4 and 56 hours after the trigger, using the High Energy Stereoscopic System (H.E.S.S.). The low luminosity and redshift of GRB 190829A reduce both internal and external absorption, allowing determination of its intrinsic energy spectrum. Between energies of 0.18 and 3.3 tera-electron volts, this spectrum is described by a power law with photon index of 2.07 ± 0.09, similar to the x-ray spectrum. The x-ray and VHE gamma-ray light curves also show similar decay profiles. These similar characteristics in the x-ray and gamma-ray bands challenge GRB afterglow emission scenarios.

Abstract
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), initially originated in China in year 2019 and spread rapidly across the globe within 5 months, causing over 96 million cases of infection and over 2 million deaths. Huge efforts were undertaken to bring the COVID-19 vaccines in clinical development, so that it can be made available at the earliest, if found to be efficacious in the trials. We developed a candidate vaccine ZyCoV-D comprising of a DNA plasmid vector carrying the gene encoding the spike protein (S) of the SARS-CoV-2 virus. The S protein of the virus includes the receptor binding domain (RBD), responsible for binding to the human angiotensin converting enzyme (ACE-2) receptor. The DNA plasmid construct was transformed into E. coli cells for large scale production. The immunogenicity potential of the plasmid DNA has been evaluated in mice, guinea pig, and rabbit models by intradermal route at 25, 100 and 500 µg dose. Based on the animal studies proof-of-concept has been established and preclinical toxicology (PCT) studies were conducted in rat and rabbit model. Preliminary animal study demonstrates that the candidate DNA vaccine induces antibody response including neutralizing antibodies against SARS-CoV-2 and also elicited Th-1 response as evidenced by elevated IFN-γ levels.

Abstract
BACKGROUND The highlight of the British Elbow and Shoulder Society pathway for the management of traumatic anterior shoulder instability is early imaging in patients aged over 40 years to assess rotator cuff integrity and early repair, if indicated to optimise function. The senior author set up a protocol in our institute to streamline the diagnostic process for this cohort of patients. This was a retrospective analysis from a prospectively collected database to highlight the importance of early specialist imaging. METHODS Our protocol is to perform urgent ultrasound scans for all suitable patients above 40 years after first-time traumatic shoulder dislocation. Demographics, associated injuries, ultrasound scan results, operations and functional outcomes were collated. RESULTS One year following the introduction of our protocol, 40 patients with a mean age of 67 (range, 42-89; SD = 13.1) had ultrasound. The incidence of full-thickness rotator cuff tears was 57.5% (n = 23). Eleven patients with confirmed full-thickness rotator cuff tears underwent surgery. The mean age of surgical patients was significantly younger than the non-surgical group (p = 0.004). DISCUSSION The use of early diagnostic imaging demonstrated a high incidence of full-thickness rotator cuff tears in this cohort of patients. This allowed early surgical repair to optimise function.

Abstract
Abstract
Introduction
To assess whether the timing of post-RARP PDE5i therapy affects early erectile function, continence, or safety outcomes.
Method
Data from 158 patients treated with PDE5is post-RARP was prospectively collected over two years from a single surgeon at one tertiary centre and retrospectively evaluated. Therapy was started: immediately (day 1-2) in 29%, early (day 3-14) in 37% and late (after day 14) post-op in 34%. EPIC-26 Erectile Function (EF) scores were collected pre-op and post-op after a median 43-day follow-up interval.
Results
Drop in EF scores and percentage return to baseline post unilateral nerve sparing (UNS) compared to bilateral nerve sparing (BNS) RARP was respectively 9 and 11.1% versus 3.5 and 42.9% of immediate therapy, 7 and 14.8% versus 5.5 and 35.5% of early and 9.7 and 9.5% versus 7.3 and 25% of late. Pad free and social continence was achieved in 54% and 37% of those receiving immediate therapy, 60% and 33% for early and 26% and 54% for late.
Conclusions
Immediate post RARP PDE5i therapy may protect EF and should be considered clinically, with more benefits for BNS than UNS patients. Immediate or early, rather than late, PDE5i therapy improved early continence in BNS patients.

Abstract
Mucoceles are common cystic lesions in the oral cavity. It may occur in different locations in the oral mucosa due to trauma or obstruction of minor salivary gland ducts with the lower lip as the predominant site. However, mucoceles located on the ventral surface of the tongue originating from the anterior lingual salivary glands are extremely rare and often overlooked during screening procedures because of their asymptomatic nature. Here, we report an interesting case of mucocele on the anterior ventral surface of the tongue in an 11-year-old female based on the clinical and histopathological diagnosis. Moreover, mucoceles should be considered as one of the differential diagnoses while evaluating a growth involving the ventral surface of the tongue in young female children.

J Family Med Prim Care 2021; 10:1327-1331. [PMID: 34041173 PMCID: PMC8140236 DOI: 10.4103/jfmpc.jfmpc_1588_20] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 09/22/2020] [Accepted: 11/24/2020] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Anemia is the commonest nutritional deficiency disorder in the world, particularly in developing countries. Though anemia is easily treatable and largely preventable disease if timely detected, it still continues to be significantly prevalent among pregnant women. AIM The aim of this study was to measure the extent of anemia in pregnancy and to assess the association of risk factors with anemia. STUDY DESIGN Hospital-based cross-sectional descriptive study. MATERIALS AND METHODS A total of 200 women were selected among pregnant women attending antenatal clinic. Sampling was done by selecting every fifth woman visiting antenatal clinic within the duration of two months on alternate days. Data were collected using a predesigned, pretested semi-structured schedule. Hemoglobin concentrations were also recorded for each patient. Data were analyzed using Chi-square test and 'T' test of significance. A value of P < 0.05 was considered significant. RESULTS We found overall prevalence of anemia to be 90% among pregnant women. Most of the anemic patients (60.5%) belong to moderate severity according to the World Health Organization classification. Three factors namely socioeconomic status, gravida and time of 1st antenatal visit were significantly associated with prevalence of anemia in pregnancy (P < 0.05). CONCLUSION In this study, a high prevalence of anemia was found in pregnant women. Low socioeconomic status, multigravida and delayed visit to antenatal clinic were significantly associated with anemia in pregnancy. So, awareness and education programs should be generated to make people come to know about anemia, its complications during pregnancy and ways to prevent it.

Abstract
Background Due to the lack of high-quality evidence which has hindered the development of evidence-based guidelines, there is a need to provide general guidance on cranioplasty (CP) following traumatic brain injury (TBI), as well as identify areas of ongoing uncertainty via a consensus-based approach. Methods The international consensus meeting on post-traumatic CP was held during the International Conference on Recent Advances in Neurotraumatology (ICRAN), in Naples, Italy, in June 2018. This meeting was endorsed by the Neurotrauma Committee of the World Federation of Neurosurgical Societies (WFNS), the NIHR Global Health Research Group on Neurotrauma, and several other neurotrauma organizations. Discussions and voting were organized around 5 pre-specified themes: (1) indications and technique, (2) materials, (3) timing, (4) hydrocephalus, and (5) paediatric CP. Results The participants discussed published evidence on each topic and proposed consensus statements, which were subject to ratification using anonymous real-time voting. Statements required an agreement threshold of more than 70% for inclusion in the final recommendations. Conclusions This document is the first set of practical consensus-based clinical recommendations on post-traumatic CP, focusing on timing, materials, complications, and surgical procedures. Future research directions are also presented.

J Oral Maxillofac Pathol 2021; 25:478-484. [PMID: 35281146 PMCID: PMC8859585 DOI: 10.4103/jomfp.jomfp_228_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Revised: 09/30/2021] [Accepted: 10/24/2021] [Indexed: 11/24/2022] Open
Abstract
Background: It has been reported that oral squamous cell carcinoma (OSCC) is associated with the presence of potentially malignant disorders (PMDs) in 15%–48% of cases. Among PMDs, oral leukoplakia (OL) is the most common, with 16%–62% of cases associated with OSCC. Hence, in the present study, we have analyzed demographic data and re-evaluated immunohistochemical (IHC) data of OL cases and aimed to correlate the clinical, histopathological and IHC aspects of OL. Materials and Methods: The data of histopathologically diagnosed cases of OL were retrieved from the archives. These data were further evaluated for age, gender, duration, site, size, side, habits, clinical staging and histopathological grading. IHC re-evaluation of OL tissues was done using epithelial cadherin (E-cadherin), n = 20; human MutL homolog 1 (hMLH1), n = 30; CD1a (n = 30); vimentin (n = 30); Ki-67 (n = 30); heat shock protein-70 (HSP-70), n = 30; p16INK4, n = 20; and mucin-1 (MUC1), n = 30. All the results and observations were subjected to descriptive statistical analysis. Results: The male: female ratio was 7.5:1; right side and buccal mucosa were more commonly affected. The duration of the lesion ranged from 1 to 30 years. One hundred and twelve patients were habituated to tobacco chewing, while 171 patients came with a combined habit of smoke and smokeless tobacco usage. Clinically, most of the lesions were of stage 2 while histopathologically they were of mild dysplasia. There was a decrease in the immunoexpression of E-cadherin, hMLH1 and CD1a, while there was an increase in the immunoexpression of vimentin, Ki-67, HSP-70, MUC1 and p16INK4. Conclusion: The study of different biomarkers such as cytoplasmic, membranous and nuclear in OL will help in better understanding and application of a reliable marker for diagnostic and prognostic purpose.
