Googling "Anatomy dissection": Pre-pandemic, pandemic, and current scenario.

OBJECTIVES: The present study was proposed to assess if the online search behavior for Anatomy dissection was affected by actual dissection being performed in the labs. The interest in dissection was ascertained and compared between pre-pandemic, pandemic, and current times. METHODS: Online web search behavior for key terms related to "Anatomy dissection" was noticed worldwide using Google Trends Tool. Relative search volume (RSV) was downloaded for these keywords worldwide using all categories, and web search settings during a period from January 1, 2018, to July 31, 2022. RESULTS: There was almost a similar google trend for the first three months in years 2018 and 2020, with a slightly lower RSV in March and a noticeable RSV decrease from April onwards in 2020. During the pre-pandemic period, the peak for RSV in the month of May was noticed. These peaks were missing in 2020 and 2021. In May 2022, RSV again increased. The top five countries with the highest search hit for "Anatomy Dissection" web were the Philippines, the United States, Canada, Australia, and India. CONCLUSIONS: There was lower search trend for "Anatomy dissection" during the pandemic period as compared to pre-pandemic period. The search trends may be associated with the closure of dissection labs and it may be concluded that Anatomy learners search for this term more often, if they are actually performing the dissections. The future integrated multi-country data and analysis from different set-ups about their ways of dissection and labs before and after the pandemic may further clarify.

The MELD Score Is Superior to the Maddrey Discriminant Function Score to Predict Short-Term Mortality in Alcohol-Associated Hepatitis: A Global Study.

INTRODUCTION: Several scoring systems predict mortality in alcohol-associated hepatitis (AH), including the Maddrey discriminant function (mDF) and model for end-stage liver disease (MELD) score developed in the United States, Glasgow alcoholic hepatitis score in the United Kingdom, and age, bilirubin, international normalized ratio, and creatinine score in Spain. To date, no global studies have examined the utility of these scores, nor has the MELD-sodium been evaluated for outcome prediction in AH. In this study, we assessed the accuracy of different scores to predict short-term mortality in AH and investigated additional factors to improve mortality prediction. METHODS: Patients admitted to hospital with a definite or probable AH were recruited by 85 tertiary centers in 11 countries and across 3 continents. Baseline demographic and laboratory variables were obtained. The primary outcome was all-cause mortality at 28 and 90 days. RESULTS: In total, 3,101 patients were eligible for inclusion. After exclusions (n = 520), 2,581 patients were enrolled (74.4% male, median age 48 years, interquartile range 40.9-55.0 years). The median MELD score was 23.5 (interquartile range 20.5-27.8). Mortality at 28 and 90 days was 20% and 30.9%, respectively. The area under the receiver operating characteristic curve for 28-day mortality ranged from 0.776 for MELD-sodium to 0.701 for mDF, and for 90-day mortality, it ranged from 0.773 for MELD to 0.709 for mDF. The area under the receiver operating characteristic curve for mDF to predict death was significantly lower than all other scores. Age added to MELD obtained only a small improvement of AUC. DISCUSSION: These results suggest that the mDF score should no longer be used to assess AH's prognosis. The MELD score has the best performance in predicting short-term mortality.

Cadaverless anatomy: Darkness in the times of pandemic Covid-19.

The pandemic Covid-19 is responsible for a major education crisis globally and has a drastic impact on medical training as well. The objective of the present study was to envision the present and future impact of Covid-19 on anatomy learning and research. The virtual education is the only mode of teaching in current scenario. Every anatomist is unlocking technology to deliver best education however understanding of the subject without dissections or other practical teaching aids like bones, specimens, embryology models, microscopic slides etc. is challenging. This approach misses the feel and human visual impacts. Potential educational disruption is felt currently and will be experienced even after the pandemic is over due to scarcity of cadavers. As the body donor may be carrier or died of Covid-19 and there is no proven screening to rule out this infection in donor, so the acceptance of body donations is not advisable for the safety of medical students and health care workers. To conclude, anatomy education is cadaverless currently due to Covid-19 lockdown and it is prophesied that after the pandemic, real cadavers will be replaced by virtual cadavers because of paucity of cadavers. Research in the field of anatomy will also be adversely affected.

Anatomy of scalenovertebral triangle: A vade mecum for clinicians.

OBJECTIVE OF THE STUDY: The thorough anatomical knowledge of scalenovertebral triangle or Triangle of the vertebral artery and its contents is crucial in various neurosurgical procedures such as scalenotomy, stellate ganglion block, direct isolation of proximal vertebral artery and proximal brachial plexus repair. MATERIAL AND METHOD: Thirty scalenovertebral triangles of known age and sex were dissected. The morphometry of the triangle and stellate ganglion was done. Various relevant distances were measured for topographical location of neurovascular structures especially stellate ganglion and vertebral artery within the triangle. RESULTS: The mean height and width of the scalenovertebral triangle was 21.7+5.1mm and 19.4+4.4mm respectively. Vertebral artery originated from subclavian artery within the triangle except in one case (left side) where it originated from aortic arch. The mean minimum distance of stellate ganglion from phrenic nerve, scalenus anterior and vertebral origin was 12.6+4.5mm, 12.26+4mm and 2.3+1.3mm respectively. CONCLUSIONS: The origin and proximal part of vertebral artery may not be present within the scalenovertebral triangle, thus topographic anatomy of the stellate ganglion is also affected and may cause complications during stellate ganglion block. Stellate ganglion is never located in the lateral or upper third of triangle. Occasionally, the phrenic nerve may cross the triangle, making it unsafe during stellate ganglion block.

Relapse of porphyria cutanea tarda after treatment with phlebotomy or 4-aminoquinoline antimalarials: a meta-analysis.

BACKGROUND: Porphyria cutanea tarda (PCT) is the most common human porphyria. It is caused by hepatic deficiency of uroporphyrinogen decarboxylase activity, which is acquired in the presence of multiple susceptibility factors. PCT presents clinically with cutaneous blistering photosensitivity and is readily treatable with either repeated phlebotomy or 4-aminoquinoline antimalarials. OBJECTIVES: To perform a systematic review and meta-analysis to compare the effectiveness of these quite different treatment approaches, especially on relapse rates (RRs) after achieving remission. METHODS: Published studies that included follow-up for at least 1 year after treatment of PCT were included. The primary study outcome was PCT relapse. Pooled data are reported as the RRs per person-year of follow-up with 95% confidence intervals (CIs). RESULTS: Of 375 articles identified as pertaining to PCT treatment, 12 were eligible for analysis. Of these, five used high-dose 4-aminoquinoline regimens (two combined with phlebotomy and three without phlebotomy), five used low-dose 4-aminoquinoline regimens and three used phlebotomy. RRs during the year after treatment were similar for the high- and low-dose 4-aminoquinoline groups (35-36%) and lower in the phlebotomy group (20%). The pooled RRs with their 95% CIs were 8·6 (3·9-13·3) per 100 person-years in the high-dose 4-aminoquinoline group, 17·1 (8·9-25·3) per 100 person-years in the low-dose 4-aminoquinoline group and 5·1 (0·5-10·6) per 100 person-years in the phlebotomy group. Subgroup and sensitivity analyses showed similar results. CONCLUSIONS: Clinical or biochemical RRs ranged from 5 to 17 per 100 person-years after remission of PCT. Relapses were somewhat more frequent after remission with 4-aminoquinoline regimens than after remission following phlebotomy. Prospective studies are needed to define better how often relapses occur with these treatments after documenting both clinical and biochemical remission of PCT.

Role of nail bed methotrexate injections in isolated nail psoriasis: conventional drug via an unconventional route.

Nail psoriasis can be a debilitating condition; however, in patients with isolated nail involvement, the use of toxic systemic therapies such as methotrexate may not be justified. We report on 4 patients (30 involved nails between them), who were treated with injections of methotrexate (0.1 mL of a 25 mg/mL solution) into the nail bed at 3-weekly intervals. Mean baseline Nail Psoriasis Severity Index (NAPSI) was 4.77 (range 2-8, cumulative score 143; n = 30); dropping successively at each visit to 2.43 (range 0-4, cumulative score 73; n = 30) at 15 weeks. The decline in mean NAPSI from 4.87 to 2.17 was statistically significant (P < 0.001; Friedman analysis). Reported adverse effects were pain, injection site pigmentation and nail bed haemorrhage. Administration of specific targeted therapy to the nail bed may help manage nail psoriasis effectively.

Optimal management of alcoholic hepatitis.

Alcoholic hepatitis, a clinical syndrome among people with chronic and active alcohol abuse presents with with jaundice and liver failure with or without hepatic encephalopathy. In patients with severe episode, this condition has a potential for 40-50% mortality within a month of presentation. Corticosteroids and pentoxifylline, only available current treatment options provide only about 50% survival benefit. Response to corticosteroids can only be assessed at 1 week of initiation of these drugs using Lille score or documentation of improvement in bilirubin levels. Requirement of minimum 6 months abstinence for liver transplantation cannot be met for alcoholic hepatitis patients who fail to respond to steroids. Emerging data on the benefit of liver transplantation for select patients with first episode of severe AH with non-response to steroids are encouraging. There remains an unmet need for studies assessing newer therapeutic targets and drugs and for optimizing the currently available treatment options. In this regard, decision to promote clinical and translational research by the National Institute of Alcohol Abuse and Alcoholism will be helpful in improving survival of patients with alcoholic hepatitis.

Management of Lateral Epicondylitis: A Prospective Comparative Study Comparing the Local Infiltrations of Leucocyte Enriched Platelet-Rich Plasma (L-aPRP), Glucocorticoid and Normal Saline.

Introduction: Lateral epicondylitis is a painful condition of the elbow, characterised by pain and tenderness with resisted wrist extension. This study was carried out to evaluate the comparative efficacy of the local infiltration of L-PRP, methylprednisolone and normal saline in patients with lateral epicondylitis. Materials and methods: Sixty adult patients, between the ages 30 to 50 years, diagnosed with lateral epicondylitis of more than 12 weeks, were enrolled in the prospective randomised study. Their medical history and previous conservative treatment were recorded; the clinical evaluation of the tendinitis was made with the visual analogue scale (VAS), the disabilities of the arm, shoulder, and hand (DASH) outcome scores, the modified elbow performance index (MEPS), the functional assessment by patient-rated tennis elbow evaluation (PRTEE), together with the laboratory investigations. The patients were randomised using the computer-generated alphabets into three groups of 20: group A received saline, group B received PRP, and group C received corticosteroids. Results: Patients were seen at 4, 8 and 12 weeks to evaluate the post-injection status. VAS, DASH, and PRTEE scores were significantly reduced, and MEPS was significantly improved in group B compared to group A and group C. Moreover, the reductions in VAS and PRTEE were significantly different in group C compared to group A. Conclusion: PRP leads to superior healing with long-term therapeutic advantages compared to corticosteroids though it takes a little longer to have its effect.

Contact depigmentation induced by propyl gallate.

We report a 41-year-old woman who developed contact depigmentation at several body sites after using lipstick, liquid kumkum (a colouring usually made from turmeric or saffron used for social/religious markings), and plastic or rubber slippers (flip-flops). Propyl gallate, a common ingredient to all and a previously undocumented depigmenting agent, was incriminated on patch testing with the Indian standard series.

Systematic review with meta-analysis: recurrence of hepatocellular carcinoma following direct-acting antiviral therapy.

BACKGROUND: Although studies suggest decreased incident hepatocellular carcinoma (HCC) after direct-acting antivirals (DAA), data are conflicting regarding HCC recurrence and aggressiveness in patients who have a history of HCC with complete response. AIM: Characterize HCC recurrence patterns after DAA therapy. METHODS: Two reviewers searched MEDLINE and SCOPUS from January 2015 to December 2017 and identified studies evaluating HCC recurrence patterns following DAA therapy. A pooled estimate was calculated using the DerSimonian and Laird method for a random effects model. The study was conducted in accordance with PRISMA guidelines. RESULTS: Among 24 studies (n = 1820 patients), the proportion of patients with HCC recurrence following DAA therapy ranged from 0% to 59% (pooled estimate 24.4%; 95% CI: 18.4%-30.4%). Among 11 full text manuscripts, pooled HCC recurrence was 21.9% (95% CI: 16.2%-28.3%). Factors associated with recurrence included history of prior HCC recurrence and a shorter interval between HCC complete response and DAA initiation. Nine studies comparing DAA-treated and interferon-treated or untreated patients found similar recurrence among DAA-treated patients. Most (77.8%) patients with HCC recurrence were detected at an early tumour stage, of whom 64.7% received curative treatment. Study limitations included heterogeneous cohorts, potential misclassification of HCC absence prior to DAA, ascertainment bias for recurrence, and short durations of follow-up. CONCLUSIONS: Current data suggest acceptable HCC recurrence rates after DAA therapy, particularly if DAA therapy is delayed at least 6 months after HCC complete response. However, data characterising HCC recurrence after DAA therapy are of limited quality, highlighting the need for high quality prospective studies.

Predictors of adequate ultrasound quality for hepatocellular carcinoma surveillance in patients with cirrhosis.

BACKGROUND: Abdominal ultrasound fails to detect over one-fourth of hepatocellular carcinoma (HCC) at an early stage in patients with cirrhosis. Identifying patients in whom ultrasound is of inadequate quality can inform interventions to improve surveillance effectiveness. AIM: To evaluate and identify predictors of ultrasound quality in patients with cirrhosis. METHODS: We performed a retrospective cohort study among patients who underwent ultrasound examination for a cirrhosis-related indication between April 2015 and October 2015. Three fellowship-trained abdominal radiologists collectively reviewed all ultrasound exams and categorised exam quality as definitely adequate, likely adequate, likely inadequate and definitely inadequate to exclude liver lesions. We performed multivariable logistic regression to determine characteristics associated with inadequate ultrasound quality. RESULTS: Among 941 patients, 191 (20.3%) ultrasounds were inadequate for excluding HCC- 134 definitely inadequate and 57 likely inadequate. In multivariable analysis, inadequate quality was associated with male gender (OR 1.68, 95% CI 1.14-2.48), body mass index category (OR 1.67, 95% CI 1.45-1.93), Child-Pugh B or C cirrhosis (OR 1.93, 95% CI 1.32-2.81), alcohol-related cirrhosis (OR 2.11, 95% CI 1.33-3.37), NASH cirrhosis (OR 2.87, 95% CI 1.71-4.80), and in-patient status (OR 1.55, 95% CI 1.01-2.37). Ultrasounds were inadequate in over one-third of patients with Child-Pugh C cirrhosis, BMI >35, or NASH cirrhosis. CONCLUSIONS: One in five ultrasounds in patients with cirrhosis are inadequate for exclusion of HCC, which can contribute to surveillance failure. Alternative surveillance modalities are needed in subgroups prone to inadequate ultrasounds including obese patients, those with Child Pugh B or C cirrhosis, and those with alcohol- or NASH-related cirrhosis.

Urethral duplication in association with anorectal malformation.

Urethral duplication is an uncommon congenital anomaly, not often reported, which may be partial or complete. Anorectal malformations are not as uncommon and they may be associated with a host of associated anomalies. However, the association of urethral duplication with anorectal malformation is rare; this report describes two such cases. In one case the intervening septum could be incised endoscopically and in the other case the duplicated urethra was excised.

Symptomatic hepatic hemangioendothelioma in a newborn.

A case of hepatic hemangioendothelioma presenting as congestive cardiac failure in a neonate is reported. There was also evidence of platelet consumption. The case was managed successfully with oral prednisolone, resulting in improvement of symptoms and tumor regression over 3 months.

Lepromatous leprosy with bilateral facial nerve palsy and hyperthyroidism.

Bilateral lagophthalmos secondary to facial nerve is extremely uncommon. Further, the aetiology in most of these cases is of central origin unlike the peripheral involvement in leprosy. A patient of lepromatous leprosy (LL) may be euthyroid or hypothyroid on account of leprous involvement of the thyroid gland. A case of LL with bilateral lagophthalmos and hyperthyroidism is reported.
