There are no Indian studies that use these criteria for diagnosis and then compare the clinical characteristics with those of normal controls. The objective of this study was to compare the clinical and biochemical profile in adolescents with and without PCOS and to study the ovarian morphology in adolescents with and without PCOS. Materials and Methods  We conducted a prospective case–control study on 60 adolescents who attended the outpatient department/adolescent immunization clinic. Group A included 30 adolescent girls with PCOS diagnosed as per the consensus criteria and Group B included 30 adolescents without PCOS. All participants were clinically evaluated and called empty stomach in the follicular phase for metabolic (Serum TSH, prolactin, FSH, LH, and testosterone) and endocrinal workup (2-hour OGTT, lipid profile) followed by ultrasonic examination. Results  In group A, 40% were overweight and 36.7% were obese and in group B, 20% were overweight and 20% were obese. There were no significant differences noted in gonadotropin levels in two groups. Mean testosterone levels were higher in PCO adolescents. The mean ovarian volume and ovarian follicle number were significantly higher in adolescents with PCOS. We found that if ultrasound criteria were added to the diagnosis, there would be about 7% lesser PCOS diagnosis. Conclusion  PCOS alters the fat distribution and lipid distribution in the body. These are features that lead to long-term metabolic alterations and life-threatening diseases. All PCOS adolescents thus be screened for these abnormalities and advised lifestyle modifications to keep these parameters under control.","PeriodicalId":53332,"journal":{"name":"Annals of the National Academy of Medical Sciences India","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42307533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diabetes mellitus is a known risk factor for invasive fungal infection. The aim of this article was to study and compare the radiological features of COVID-19-associated ROCM between diabetic and nondiabetic patients using magnetic resonance imaging. Materials and Methods  A retrospective observational study comprising 78 diabetics and 40 nondiabetics who developed ROCM after COVID-19 was conducted. The imaging data of both groups were analyzed, findings tabulated and compared using statistical methods. Results  Maxillary and ethmoid sinuses were commonly involved in both groups. Periantral fat and orbits were the most common sites of disease extension. The spread of infection to periantral soft tissue was significantly higher in diabetics ( p = 0.049). Diabetics were more likely to have bone, orbit, and brain involvement than nondiabetics, although the difference was not statistically significant. Diabetic patients were the only ones to experience complications such as fungal abscess and cavernous sinus and internal carotid artery involvement. However, a considerable number of nondiabetic patients (22.5%) also had an intracranial extension of disease. Conclusion  The radiological appearances and common sites of invasion in ROCM are similar in diabetic and nondiabetic patients. The extensive spread of infection to extra-sinus regions can occur in nondiabetic patients with COVID-19 but is less frequent compared with diabetics.","PeriodicalId":53332,"journal":{"name":"Annals of the National Academy of Medical Sciences India","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45961601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This problem occurring in the development phase of the child affects not only the vision but also the general development, if not diagnosed and managed in time. Moreover, some forms may even harbor a neurological tumor needing timely management. First, a brief introduction of nystagmus classification, a simplified approach to diagnose the common childhood nystagmus, and the value of electrophysiology will be presented. Next, the approach to treatment, using a thorough clinical examination, illustrated by patient examples of different types of nystagmus will be presented. The different forms of childhood nystagmus are described: idiopathic infantile nystagmus syndrome (IINS), sensory nystagmus (SN), fusion maldevelopment nystagmus (FMDN), spasmus nutans syndrome (SNS), nystagmus blockage syndrome, periodic alternating nystagmus, and others as well as their specific management. The role of electronystagmography and that of neuroimaging in specific conditions is life saving and is described. The role of auditory biofeedback, acupuncture, medical treatment, and surgical procedures like Augmented Anderson procedure, Hertle-Dell'Osso procedure, supra maximal retro-equatorial recession, and posterior fixation have been elucidated. Newer techniques have simplified the management options and improved the functional outcomes in childhood nystagmus. To conclude, children with nystagmus of types IINS, FMDN, SNS, or SN need to be managed differently. It is thus possible to timely manage these children, not only to save their life and improve their vision but also to improve their living quotient.","PeriodicalId":53332,"journal":{"name":"Annals of the National Academy of Medical Sciences India","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49131778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Literature available on ocular surface changes has predominantly been reported in patients undergoing hemodialysis. Little is known about the changes in patients undergoing peritoneal dialysis. The present study aimed to identify ocular surface changes in an idiopathic group of CKD undergoing dialysis. Aim  To compare tear film disorders and the severity of ocular surface changes (goblet cell density, squamous metaplasia, and corneoconjunctival calcification) in patients of idiopathic etiology with CKD undergoing hemodialysis and peritoneal dialysis. This is an analytical study. Materials and Methods  Asymptomatic adult patients of idiopathic CKD, on treatment with dialysis underwent comprehensive ophthalmic examination, including best-corrected visual acuity, slit-lamp examination, and a dilated fundus examination. Dry eye assessment was done by ocular surface staining score, Schirmer test, and tear breakup time (TBUT). Conjunctival impression cytology was studied to assess changes on ocular surface. Chest X-rays for aortic calcification were reviewed and data analyzed. Results  Both eyes of 76 patients of hemodialysis and 32 patients of peritoneal dialysis were studied. Ocular surface staining (OSS) scores were low. Impression cytology showed a drop in goblet cell density, presence of squamous metaplasia, and conjunctival keratinization significantly more in the hemodialysis group. No correlation was seen between the presence of conjunctival calcification and aortic calcification. Conclusion  The hemodialysis group had mild subclinical dry eye but keratinization of conjunctiva was seen. Similarly, advanced squamous metaplasia was seen in the peritoneal dialysis group. These changes were positively correlated to decrease in goblet cell density.","PeriodicalId":53332,"journal":{"name":"Annals of the National Academy of Medical Sciences India","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46656415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The disease, first noticed in the Wuhan province, moved to the entire world in a short period. There were a large number of people with mild symptoms, some with severe forms of the disease, and some in very severe stage, resulting in their death. In total, 425 million people suffered, 351 million fully recovered, and 6 million died worldwide. This sudden disease crisis has united every one across the globe to control and minimize the severity of the disease. Toward this goal, scientists, doctors, and researchers are engaged with studies on the disease, disease-causing viruses, treatment regimen, and some other developed vaccines to prevent the illness. In a routine standard procedure, inventing a new drug or vaccine takes a few years from thought to clinical trials. However, in the present day, technology has advanced so much that it has come up with answers in a short time. That is how we have a few vaccines against COVID-19 disease ready for use in an emergency. In all these ventures, strict procedures, protocols, ethical considerations, and regulatory requirements have been adhered to and only upon such satisfaction they have been released for use in the population. The governments have taken a decision to use these vaccines on their people. They have made widely dispersed information about vaccines available to people through popular media. The questions can be numerous: “has this information reached the grassroots level, have people understood the benefits and risks, is the information adequate to make informed consent to take the vaccines, whowill receive the vaccines first, given the limited supply.” There is a need for studies on all these issues from different parts of the geography, different culture, different ethnicity cutting across borders. The situation is peculiar, vaccine put up in short period, launched nationwide, what in the event of adverse side effects, what if sizeable population refuse vaccination? In any given scenario, there are persons with advanced age, disability, chronic disease, dependency internet surfers, rumor mongers, atheists who may flatly refuse to take the vaccine. If such persons are influential, they may induce others not to take the shots. In our observation of a group of health workers, few 1% refused fully, 5% pretended with lame excuse to take vaccine, and 12% were undecided.

At the same time, physical and mental well-being of women relies on healthy lifestyle and adequate reproductive health knowledge. With growing incidence of polycystic ovarian syndrome (PCOS), it is crucial to increase awareness about the disease among women at an early age in life. The present survey investigates awareness level of college going females about PCOS. Materials and Methods  428 females were recruited from 3 colleges in district Gurgaon, Haryana, India, based on convenience sampling. The respondents filled a self-completion questionnaire containing sociodemographic details, menstrual cycle details, and questions related to PCOS. Statistical Analysis  Descriptive statistics was used to calculate frequency and percentage of variables. Pearson's chi-square test of independence was used to identify factors associated with awareness of PCOS. A p -value of < 0.05 was considered to be statistically significant. Results  The mean ±SD age of respondents was 19.9 ± 1.7 years (range = 18–24 years). Only 78 females (18.22%) had heard about PCOS.
