Introduction:This is a case study of 61 cases admitted in our hospital to study the various etiologies of vocal cord immobility (including both paralysis and paresis of vocal cord) and to study the incidence of vocal cord immobility.Vocal cord paralysis is a common symptom of the disease which can be originated from laryngeal nerve paralysis following laryngeal carcinoma, oesophageal carcinoma, bronchogenic cancers, thyroid neoplasms, surgical procedures in neck and thorax, post anaesthesia complication,or neurologic diseases. Materials and methods:The present study includes all the cases having vocal cord paralysis presenting in out-patient department of Otorhinolaryngology, examination of larynx externally,by indirect laryngoscopy and direct laryngoscopy was done.All the routine and systemic examination were done. Results:In our study, left vocal cord was the most commonly involved and was observed in 40(65.5%) patients, with neoplasm being the most common cause in 19(31.1%) patients. Right vocal cord involvement was found in 20(32.8%) patients, with neoplasm being the most common cause in 13 (21.3%) patients. The ratio of left side and right side involvement of vocal cord was 2:1 in our study. The longer course of the Left Recurrent Laryngeal Nerve might account for the difference. Conclusion:In our study the etiology which was found to be more common was neoplasms then that of idiopathic causes. The reason behind this could be advanced investigation procedures which allows us to do a thorough work upon any case, but even after that we have found some of Idiopathic causes as well.

Objective The Liver Imaging Reporting and Data System (LI-RADS) has been widely applied to CT and MR liver observations in patients at high-risk for hepatocellular carcinoma (HCC). We investigated the impact of CT vs MR in upgrading LI-RADS 3 to LI-RADS 5 observations using a large cohort of high-risk patients. Methods We performed a retrospective, longitudinal study of CT and MR radiographic reports (June 2013 - February 2017) with an assigned LI-RADS category. A final population of 757 individual scans and 212 high-risk patients had at least one LI-RADS 3 observation. Differences in observation time to progression between modalities were determined using uni- and multivariable analysis. Results Of the 212 patients with a LI-RADS 3 observation, 52 (25%) had progression to LI-RADS 5. Tp ranged from 64 - 818 days (median: 196 days). One hundred and three patients (49%) had MR and 109 patients (51%) had CT as their index study. Twenty-four patients with an MR index exam progressed to LI-RADS 5 during the follow-up interval, with progression rates of 22% (CI:13%-30%) at 1 year and 29% (CI:17%-40%) at 2 years. Twenty-eight patients with a CT index exam progressed to LI-RADS 5 during follow-up, with progression rates of 26% (CI:16%-35%) at 1 year and 31% (CI:19%-41%) at 2 years. Progression rates were not significantly different between patients whose LI-RADS 3 observation was initially diagnosed on MR vs CT (HR: 0.81, P = 0.44). Discussion MR and CT modalities are comparable for demonstrating progression from LI-RADS 3 to 5 for high risk patients.

Psoriasis is a common, chronic and non- infectious skin disease characterized by well defined slightly raised, dry erythamatous macules with silvery scales Modern medicine offers treatment with PUVA, Corticosteroids & Anti mitotic Drugs but therapy gives serious side effects like Bone Marrow depletion, Liver & kidney Failure. While treating Kustha, Ayurvedic Classics especially focused on Panchakarma Treatment. So Vaman, Virechana & Laghu-Manjisthadi Ghan was selected for trial. Total 30 well diagnosed patients were selected & divided in two groups. One group receiving Ayurvedic Treatment & other Allopathic Regimen (Tb.Methotraxate7.5 mg/week) for 2 months & comparative study was done. Assessment was done on improvement in clinical symptoms as well as on Laboratory parameters.

Linear calcinosis cutis is a very rare disorder; reported in association with lichen sclerosus etatrophicus, scleroderma, after intravenous infusion of calcium and acute monocytic leukemia. In available literature, idiopathic zosteriform calcinosis cutis is yet to be described. An 8-year-old child presented with spontaneous painful, slowly progressive, linear band-like nodules over the right half of the chest and back of the trunk. Histopathology with special stains was done to confirm the diagnosis. The patient was treated with diltiazem and responded well. We report a case of idiopathic zosteriform calcinosis cutis because of unusual presentation and rarity of the disorder.

Context: Inguinal skin is prone to various infectious dermatological conditions such as erythrasma, intertrigo, hidradenitis suppurativa, folliculitis, dermatophytic infection, and various sexually transmitted diseases, as compared to the skin elsewhere. Aim: Our study attempts to compare the biophysical profile parameters (BPPs) of the genital skin with that of the rest of the body, while taking skin of the upper back as control. It also attempts to find out if there is a difference in BPPs of the two sites and that how the change in the BPPs, bring about change in microbiome and make inguinal skin more prone to infections. Materials and Methods: This was a hospital-based comparative study conducted over 976 patients (600 males and 376 females) of age group 18–60 years, where BPP parameters such as hydration, skin pH, transepidermal water loss (TEWL), and sebum content were measured over the skin of the upper back and right inguinal region, and the results were summarized and presented as proportions (%). Chi-square test was used to compare abnormal findings. P ≤ 0.05 was taken as statistically significant. MedCalc 16.4 version software was used for all statistical calculations. Results: Significant difference was noted in skin pH and TEWL, where P value came out to be

The duodenum can be affected by a variety of abnormalities because of its development during embryogenesis and its dual intra- and retroperitoneal location. If small bowel embryogenesis is disturbed, congenital errors occur. Although some congenital variants may be asymptomatic and inconsequential to the patient, other anomalies can result in life-threatening emergencies such as malrotation, leading to midgut volvulus. Many infectious processes affect the duodenum, including duodenal ulcers and opportunistic infection in patients with HIV/AIDS or Crohn disease. Small bowel malignancies are uncommon but important to recognize, because the duodenum can be involved in polyposis syndromes or the development of primary adenocarcinoma, neuroendocrine tumors, lymphoma, and metastasis. Although endoscopy is currently the most used diagnostic method to assess the lumen of the upper gastrointestinal tract, fluoroscopy is a valuable adjunct technique and the study of choice for many diseases, specifically those for which anatomic and functional information is required. Fluoroscopy is also commonly used postoperatively to assess for complications such as obstruction and extraluminal leaks. Compared with endoscopy, fluoroscopy is an inexpensive and noninvasive technique that provides salient anatomic information and allows delineation of the duodenal mucosa and assessment of real-time duodenal motility. The authors examine the broad spectrum of conditions that can involve the duodenum, including congenital, infectious, inflammatory, and neoplastic abnormalities, and review their typical appearances at fluoroscopy.

Aspergillosis is an uncommon fungal infection in which primary cutaneous sites are very rare. Most cases occur in immunocompromised patients and infection in immunocompetent patients, is extremely rare, but an increase in prevalence has been noted in last 20 years. A case of primary cutaneous aspergillosis (PCA) in a 40-year-old immunocompetent shopkeeper resident of Jaipur Rajasthan presenting with verrucous growth on the lower lip has been reported in this case study.

Purpose To evaluate the impact of environmental and socioeconomic factors on outpatient cancellations and “no-show visits” (NSVs) in radiology. Materials and Methods We conducted a retrospective analysis by collecting environmental factor data related to outpatient radiology visits occurring between 2000 and 2015 at our multihospital academic institution. Appointment attendance records were joined with daily weather observations from the National Oceanic and Atmospheric Administration and estimated median income from the US Census American Community Survey. A multivariate logistic regression model was built to examine relationships between NSV rate and median income, commute distance, maximum daily temperature, and daily snowfall. Results There were 270,574 (8.0%) cancellations and 87,407 (2.6%) NSVs among 3,379,947 scheduled outpatient radiology appointments and 575,206 unique patients from 2000 to 2015. Overall cancellation rates decreased from 14% to 8%, and NSV rates decreased from 6% to 1% as median income increased from $20,000 to $120,000 per year. In a multivariate model, the odds of NSV decreased 10.7% per $10,000 increase in median income (95% confidence interval [CI]: 10.3%-11.1%) and 2.0% per 10°F increase in maximum daily temperature (95% CI: 1.3%-1.6%). The odds of NSV increased 1.4% per 10-mile increase in commute distance (95% CI: 1.3%-1.6%) and 4.5% per 1-inch increase in daily snowfall (95% CI: 3.6%-5.3%). Commute distance was more strongly associated with NSV for those in the two lower tertiles of income than the highest tertile (P Conclusion Environmental factors are strongly associated with patients’ attendance at scheduled outpatient radiology examinations. Modeling of appointment failure risk based on environmental features can help increase the attendance of outpatient radiology appointments.

Melanonychia is a brownish-black staining of the nail plate. It can affect a single or several nails on both the fingers and toes. Melanocytic activation and melanocytic hyperplasia are the two basic mechanisms involved in the development of melanonychia. Melanocytic activation occurs as enhanced melanic pigmentation of the nail matrix epithelium and nail plate without a corresponding rise in the number of melanocytes, resulting in melanonychia. The number of matrix melanocytes increases in melanocytic hyperplasia. Involvement of a pathogen has also been suggested as a mechanism for its development. A thorough clinical history should be taken, including questions regarding various triggers and causal events, as well as the use of a questionnaire. A proper detailed physical examination is of a great need to properly identify the type of melanonychia and to rule out melanoma which is of great importance in clinical practice. Onychoscopy and nail biopsy also acts as an aid in proper diagnosis of melanonychia. Treatment of melanonychia basically depends on the underlying etiology. One major aim is to rule out melanoma if present and its proper management in time.

Aim: We sought to identify predictors of progression of an indeterminate observation (LI-RADS 3) to hepatocellular carcinoma (LI-RADS 5). Methods: Imaging reports with LI-RADS (LR) assignments were identified among patients at the University of Washington, 2013-2017. Patients with an LR3 lesion and follow-up scan within 1 year of LR3 lesion date were included (n = 313). Features of interest were abstracted from chart review. Survival analyses employing interval censoring were performed, with variables potentially predictive of LR3 progression identified in univariate analyses. Backwards elimination (P < 0.05) was used to obtain the final multivariate model. Results: 20.4% of LR3 lesions progressed to LR5; 73% remained LR3, 8% LR4. The cohort was predominantly male (61%), Caucasian (54%), older than 55 (63%). 47% had a history of hepatitis C virus (HCV), 33% with alcohol abuse, not mutually exclusive. Alpha-fetoprotein (AFP) at the time of LR3 scan was low if available (39% with AFP < 5, 29% unknown). CT was the most common exam (56%). Men (HR = 2.0, P = 0.02), earlier scan year (HR = 0.47 per year, P < 0.0001), and older age (HR = 1.48, P = 0.03), appeared as predictors of LR progression in the final model. HCV and alcohol use were more common among men but did not appear to explain the difference in LR progression by sex. Conclusion: Our analysis is an early exploration of characteristics that may predict the risk of progression of an LR3 observation to hepatocellular carcinoma. Future efforts may allow for risk stratification to identify high-risk indeterminate lesions that may benefit from earlier intervention or more frequent surveillance.

We have all been guilty of making ineffective presentations at some point in our career. In this article we explore the key principles behind “Presentation Zen,” an approach intended to decrease cognitive overload, make presentations more visual, natural, and unique; as well as improve the overall impact of our presentations by allowing the listener to process the information while listening to the presenter.

To analyze the trends in international medical graduates (IMGs) matching into diagnostic radiology residency programs in the United States (US).The National Resident Match Program data was accessed for years 2005-2020 and diagnostic radiology residency-specific data was extracted for US MD, osteopathic (DO), and IMG applicants. IMGs were categorized into US-citizen IMGs and non-US citizen IMGs per the National Residency Match Program. Variables collected for each year included the number of positions, number of applicants in each group, positions filled/unfilled, and fill rate of each group. Additional data for some years included USMLE Step 1 score, United States Medical Licensing Examination (USMLE) Step 2 clinical knowledge (CK) score, number of research experiences, number of abstracts/publications, and additional degrees obtained. Trends were analyzed using simple linear regression model and p value0.05 was considered significant.The number of diagnostic radiology residency programs increased from 203 (2006) to 212 (2020). The total number of diagnostic radiology residency positions increased from 1011 (2006) to 1113 (2020), with the peak of 1145 in 2014. The overall "match rate," that is, proportion of positions filled to positions available, increased from 96.4% (2006) to 97.3% (2020), with a brief decline to 86.7% in 2015. Among the filled positions, the proportion filled by US medical school graduates significantly declined from 89.7% (2006) to 69.2% (2020) (p0.001), and the proportion of positions filled by osteopathic seniors and graduates significantly increased from 2.2% (2006) to 15.1% (2020; p0.001). The proportion of US IMGs increased from 3.2% (2006) to 5.4% (2020), while the proportion of non-US IMGs increased from 4.4% (2006) to 9.4% (2020), with overall IMG match rate increased significantly from 7.6% to 14.9% (p = 0.009). The mean Step 1 scores of US IMGs and non-US IMGs were 238 and 237.3, and the mean Step 2 CK scores were 241.67 and 241, respectively. Cumulatively over the study period, a total of 736 US IMGs and 1051 non-US IMGs have matched into diagnostic radiology residency.There is an increasing proportion of IMGs, especially the non-US citizen IMGs, matching into US radiology residency programs in the last decade. Diagnostic radiology remains a competitive specialty evidenced by average USMLE scores higher than national average and research experiences of matched candidates.

This study compares the results of Tympanoplasty in terms of graft uptake and hearing improvement in patients with Chronic Otitis Media which are divided on the basis of discharging ear and non discharging ear with perforation at the time of surgery. Total 110 patients were selected suffering from chronic otitis media. Out which 55 patients had discharging ear (wet ear) and 55 patients had non discharging ear (dry ear). Tympanoplasty was performed using temporalis fascia graft. Hearing improvement and graft uptake was seen in both wet and dry ears. No statistically difference is noted in the results between the two. Mucoid ear discharge at the time of surgery is not a contraindication for Tympanoplasty as it has no adverse effects on the outcomes of the surgery in respect to graft uptake and hearing improvement.

Purpose Computed tomography (CT) is a fast and ubiquitous tool to evaluate intra-abdominal organs and diagnose appendicitis. However, traditional CT reporting does not necessarily capture the degree of uncertainty and indeterminate findings are still common. The purpose of this study was to evaluate the reproducibility of a standardized CT reporting system for appendicitis across a large population and the system's impact on radiologists' certainty in diagnosing appendicitis. Methods Using a previously described standardized reporting system, eight radiologists retrospectively evaluated CT scans, blinded to all clinical information, in a stratified random sample of 237 patients from a larger cohort of patients imaged for possible appendicitis (2010-2014). Receiver operating characteristic (ROC) curves and the area under the ROC curve (AUC) were used to evaluate the diagnostic performance of readers for identifying appendicitis. Two-thirds of these scans were randomly selected to be independently read by a second reader, using the original CT reports to balance the number of positive, negative and indeterminate exams across all readers. Inter-reader agreement was evaluated. Results There were 113 patients with appendicitis (mean age 38, 67% male). Using the standardized report, radiologists were highly accurate at identifying appendicitis (AUC=0.968, 95%CI confidence interval: 0.95, 0.99. Inter-reader agreement was >80% for most objective findings, and certainty in diagnosing appendicitis was high and reproducible (AUC=0.955 and AUC=0.936 for the first and second readers, respectively). Conclusions Using a standardized reporting system resulted in high reproducibility of objective CT findings for appendicitis and achieved high diagnostic accuracy in an at-risk population. Predictive tools based on this reporting system may further improve communication about certainty in diagnosis and guide patient management, especially when CT findings are indeterminate.

Background: Alopecia areata (AA) is a common, recurrent form of nonscarring alopecia which often presents as circumscribed patches of spontaneous hair loss. The global prevalence of this disease varies from 0.1% to 0.2% in general population and 7–30 cases per 1000 dermatological patients. The etiology of AA still remains uncertain; however, genetic or environmental factor and autoimmunity are claimed responsible for it. Various autoimmune diseases, such as Hashimoto's thyroiditis, diabetes mellitus, vitiligo, and lupus erythematosus, have been reported in association with AA. Aim: The index study was aimed at estimation of serum T3, T4, thyroid-stimulating hormone, and antithyroid peroxidase (TPO) antibodies. Material and Methods: Similar age/sex-matched AA patients and controls (110 in each group). Enhanced chemiluminescence immunoassay for thyroid profile and anti-TPO antibody level estimation in veinous blood sample. Observations: The mean/standard deviation (SD) of T3 was 3.30 ± 0.84 pg/ml in AA while 3.27 ± 0.67 pg/ml in controls (P = 0.302). Serum mean/SD of T4 level was1.23 ± 0.76 ng/dl in AA patients while 1.17 ± 0.34 ng/dl in controls (P = 0.522). The mean/SD of anti-TPO levels in AA patients was 21.52 ± 35.09 while 56.43 ± 140.72 in controls (P = 0.136). Limitation: The limitation of this study was moderate number of AA patients and different genotype of study population. Conclusion: Occurrence of thyroid dysfunction and evidence of anti-TPO antibodies in AA is rare event in this study population.

Context: Recently, there has been an increase in the number of chronic, recurrent, and recalcitrant dermatophytosis. Many factors implicated are barrier defects, aberrant host immune response, application of steroids or other irrational combination creams, transmission within family, occlusive clothing, poor hygienic conditions, poor compliance, drug resistance and virulence of the infecting strain. Transepidermal water loss (TEWL) is an important index in accessing the barrier function of skin. Aim: To ascertain the role of TEWL from the lesional skin and its effect on the cure rate and relapse in patients of tinea cruris. Materials and Method: A hospital based prospective comparative study was conducted for 1 year. A total of 200 patients of tinea cruris diagnosed clinically and by KOH examination, were included in the study. TEWL was calculated using Tewameter TM300 open chamber probe of Courage and Khazaka, Cologne, Germany. Patients were classified according to the TEWL values into Group A (patients with abnormal TEWL) and Group B (normal TEWL). Both groups were given oral itraconazole and antihistamines for 4 weeks. The cure rates and recurrence rates of both the groups were analyzed and compared. Results: In the Group A, i.e., patients of tinea cruris with abnormal TEWL, only 28% of the patients showed clinical improvement at the end of 1 month. Out of those cured, 78.57% of the cases showed recurrence after 2 months of completion of therapy. In Group B, i.e., patients of tinea cruris with normal TEWL, 69% (n = 69) of the patients showed clinical improvement at the end of 1 month. Out of those cured, only 21.74% of the cases (n = 15) showed recurrence. Conclusion: The cases of tinea cruris with abnormal TEWL show significant decrease in cure rates and significant relapse rates among those initially cured.

Introduction: Acne vulgaris is a chronic inflammatory disorder of the pilosebaceous units and has been associated with hyperandrogenism, which, in women, is most commonly caused by polycystic ovary syndrome (PCOS). Metformin treatment can correct ovarian and functional adrenal hyperandrogenism in adolescents with PCOS. Objective: We evaluated the efficacy of metformin therapy in women with acne and PCOS in terms of acne load. Methods: This was a hospital-based, interventional, longitudinal study that included 40 female patients with acne and PCOS diagnosed using the Rotterdam criteria. Hormonal assay, including serum levels of testosterone, dehydroepiandrosterone sulphate, luteinizing hormone, follicle-stimulating hormone, prolactin, and blood sugar, was conducted on the third or fourth day of the menstrual cycle in a fasted state. An abdominal ultrasound was performed on the ninth day of menstrual cycle to diagnose PCOS. Baseline acne severity was assessed as per the Definition Severity Index. Metformin 500mg was given to all selected patients three times a day for eight weeks. Patient follow-up and acne severity reassessment was conducted at Weeks 3 and 6. At Week 8, all work-ups were repeated. Intention-to-treat analysis was done. Wilcoxin signed-rank sum test was used to identify significance in acne severity. Results: Metformin treatment significantly reduced acne severity in patients with PCOS (p

In the beginning of the COVID-19 pandemic when we were still getting used to the rising cases every day and limited resources to deal them with, the focus was to get a hold of the situation as quickly as possible. Seven months into the pandemic, the cases are still on the rise but we have gathered some knowledge through the researches getting published every day, most of which are focused on the involvement of respiratory system, cardiovascular system, central nervous system, and gastrointestinal system. Dermatological manifestations have not been given their due importance. Lately, many patients have started presenting with dermatological manifestation sometimes preceding or sometimes during COVID-19 infection with or without involvement of other systems. This may be beneficial to clinicians all over the world, to determine potential dermatological signs in COVID-19 and also help in earlier suspection of the COVID-19 infection. Many cutaneous adverse drug reactions (ADR) to drugs advocated in COVID-19 treatment are also being reported every day, which are discussed in this review.Here we attempt to review dermatological manifestations of COVID-19 infections and drug reactions by the drugs advocated for its treatment and an understanding in its path mechanisms reported thus far. This will help clinicians to get an insight into what to expect and when to expect in terms of dermatological manifestation of COVID-19 and its drugs.

Purpose To investigate performance in detectability of small (≤1 cm) low-contrast hypoattenuating focal lesions by using filtered back projection (FBP) and iterative reconstruction (IR) algorithms from two major CT vendors across a range of 11 radiation exposures. Materials and Methods A low-contrast detectability phantom consisting of 21 low-contrast hypoattenuating focal objects (seven sizes between 2.4 and 10.0 mm, three contrast levels) embedded into a liver-equivalent background was scanned at 11 radiation exposures (volume CT dose index range, 0.5-18.0 mGy; size-specific dose estimate [SSDE] range, 0.8-30.6 mGy) with four high-end CT platforms. Data sets were reconstructed by using FBP and varied strengths of image-based, model-based, and hybrid IRs. Sixteen observers evaluated all data sets for lesion detectability by using a two-alternative-forced-choice (2AFC) paradigm. Diagnostic performances were evaluated by calculating area under the receiver operating characteristic curve (AUC) and by performing noninferiority analyses. Results At benchmark exposure, FBP yielded a mean AUC of 0.79 ± 0.09 (standard deviation) across all platforms which, on average, was approximately 2% lower than that observed with the different IR algorithms, which showed an average AUC of 0.81 ± 0.09 (P = .12). Radiation decreases of 30%, 50%, and 80% resulted in similar declines of observer detectability with FBP (mean AUC decrease, -0.02 ± 0.05, -0.03 ± 0.05, and -0.05 ± 0.05, respectively) and all IR methods investigated (mean AUC decrease, -0.00 ± 0.05, -0.04 ± 0.05, and -0.04 ± 0.05, respectively). For each radiation level and CT platform, variance in performance across observers was greater than that across reconstruction algorithms (P = .03). Conclusion Iterative reconstruction algorithms have limited radiation optimization potential in detectability of small low-contrast hypoattenuating focal lesions. This task may be further complicated by a high degree of variation in radiologists' performances, seemingly exceeding real performance differences among reconstruction algorithms. © RSNA, 2018 Online supplemental material is available for this article.
