Published: January 2024

Abstract

Background:
A critical illness such as severe coronavirus disease 2019 (COVID-19) activates autonomic, endocrine, and emotional stress responses. Whether the manifestations of excessive stress experience persist beyond full recovery into the intermediate post-COVID period (3–6 months after recovery) is not known and was the question we addressed in the current study.

Methods:
An analytical observational cross-sectional study compared the heart rate variability (HRV), 8 AM serum cortisol concentration, and the Depression, Anxiety, and Stress Scale–21 (DASS-21) scores between COVID-19 recovered participants and their age-matched control subjects (21 male participants, 30–70 years of age, in each group).

Results:
The median (Q1–Q3) of low frequency (LF), high frequency (HF), and total powers of HRV was significantly reduced in those who recovered from severe COVID-19, compared to control subjects (respectively LF power: 410.871 [245.10–861.94], 947.57 [536.11–1778.55], P = 0.011; HF power: 192.916 [87.66–564.43], 705.18 [248.67–1192.19] P = 0.013; Total power: 646.33 [308.72–1518.28], 1613.33 [956.14–4022.55] P = 0.015, Mann–Whitney U-test). Serum cortisol and DASS-21 scores were not different from the control group.

Conclusions:
Impaired cardiac autonomic function, evidenced by reduced HRV, was observed in the intermediate period following recovery from severe COVID-19. However, psychological stress and elevated serum cortisol were not noted. Our result that exposes the effect of COVID-19 on cardiac autonomic responsiveness is important as diminished HRV increases the vulnerability of COVID-19 survivors to diseases. These findings may also suggest a focus of therapy in them, as specific interventions are known to improve HRV and cardiac autonomic functioning.

Abstract
Muscle involvement is common in hypothyroidism and is seen in nearly 80% of the cases. However, rhabdomyolysis is a rare manifestation and is usually triggered by precipitating factors such as exercise, statins, and toxins. We describe the case of a 58-year-old woman with de novo hypothyroidism presenting with severe rhabdomyolysis requiring hemodialysis. A 58-year-old diabetic and hypertensive female was presented at our tertiary care center with symptoms of generalized weakness, difficulty in walking, and decreased urine output. Her blood investigations showed elevated creatine phosphokinase (CPK), renal parameters, and thyroid-stimulating hormone (TSH) levels suggestive of autoimmune thyroiditis with rhabdomyolysis. She was treated with thyroid hormone supplementation and hemodialysis. The patient recovered gradually with normalization of renal parameters. Although muscle involvement is common in hypothyroidism, rhabdomyolysis is a rare manifestation. Diagnosis is established by demonstrating elevated CPK and TSH levels. Management consists of hydration and thyroid hormone supplementation. Hemodialysis is required in severe cases with established acute kidney injury.

Published: January 2024

Abstract
Histiocytic sarcoma (HS) is a rare malignant neoplasm of presumed hematopoietic origin, showing morphologic and immunophenotypic evidence of histiocytic differentiation. A 61-year-old woman presented with an abdominal mass. She had a history of HS in both adrenal glands. The tumour cells of the left adrenal gland were very large epithelioid cells with abundant eosinophilic cytoplasm and large, round-to-oval nuclei. Similarly, the cutaneous lesion of the skin was composed of polygonal cells with well-defined cell borders and high nuclear/cytoplasm (N/C) ratios. Immunohistochemically, both tumours were positive for histiocyte-associated antigens but negative for epithelial, melanocyte, lymphoid, dendritic, and Langerhansl nuclei. Similarly, the cutaneous lesion of the skin was composenose correctly. It is important to recognise the morphological features and immunohistochemical characteristics of metastatic cells in order to achieve accurate diagnoses.

Published: January 2024

Abstract
The human monkeypox (mpox) virus is an orthopox virus that can be transmitted to humans. Though the disease has been endemic in Africa, the recent mpox outbreak since May 2022. We attempted to examine differences between the endemic form of mpox and the current outbreak. Review of electronic medical database with relevant keywords. The current outbreak of mpox has disproportionately impacted the gay, bisexual and other men who have sex with men (MSM) community. This is also the first time that widespread semen testing has turned up evidence of mpox viral deoxyribonucleic acid (DNA). Cases in the present outbreak are more likely to affect adults, involve the genitalia, and have no prodrome. Close diagnostic differentials include varicella and hand-foot-mouth disease. The disease is usually self-limiting; though secondary infections, anorectal pain, pharyngitis, ocular lesions and rarely, renal injury and myocarditis may occur. This review focuses primarily on the novel clinical characteristics and emerging sexual transmission route of the mpox virus, which, although unconfirmed, appears extremely likely as the route of spread. Dermatologists have an important role in this health emergency, as early diagnosis can cause a significant reduction in disease transmission.

Authors: Erduran Funda , Adışen Esra , Soyugür Ahmet , Eren Funda , Neşelioğlu Salim , Erel Özcan 
Published: January 2024

Abstract

Background:
Mycosis fungoides (MF) is the most common cutaneous T-cell lymphoma with unknown etiopathogenesis. Oxidant and antioxidant balance is important for cell function and normal metabolism. An imbalance between pro-oxidants and antioxidants causes oxidative stress. A recent focus has been on thiol/disulphide homeostasis as a novel marker of oxidative stress.

Aims and Objectives:
This study aimed to evaluate the role of oxidative stress in MF by analysing thiol/disulphide homeostasis.

Materials and Methods:
A total of 103 patients (48 female, 55 male) and a control group of 120 healthy individuals (48 female, 72 male) from two tertiary care hospitals were included in our study. Serum native thiol, total thiol and disulphide levels were evaluated using novel method developed by Erel and Neeliolu.

Results:
Native thiol levels were 340.30 ± 87.44 in the patient group and 401.62 ± 69.45 in the control group. Total thiol value was 374.17 ± 87.78 in the patient group and 428.54 ± 70.05 in the control group. Native thiol and total thiol levels were significantly lower in the patient group compared to the control group (P < 0.001 and P < 0.001). The disulphide value was 16.93 ± 6.46 in the patient group and 13.46 ± 5.06 in the control group. Disulphide levels were found to be significantly higher in the patient group compared to the control group (P < 0.001).

Conclusions:
In our study, thiol/disulphide balance shifted towards disulphide which indicates the presence of oxidative stress especially in the early stage while 93.2% of our patients had early-stage MF. We think that this may have pathogenetic and prognostic significance.
Comparison of Serum Levels of Interleukin 17 and Interleukin 9 in Leprosy Patients with and without Lepra Reaction: A Cross-Sectional Analytical Study from Central India
Authors: Choudhary Ritul , Chhabra Namrata , Patel Suprava 
Published: January 2024

Abstract
New pathways of host defence have emerged in leprosy, such as T helper (Th) -17, Th-9, T regulatory cells, and other factors like transforming growth factor-beta, etc. Interleukin (IL) 17 produced by Th17 cells has been found to be elevated in lepra reaction, especially type 2 lepra reaction (T2R). Role of IL-9 has not been studied widely in leprosy reactions so far. The study aimed to compare serum levels of IL-17 and IL-9 in leprosy patients with and without lepra reaction. This was a cross-sectional analytical study including untreated adult leprosy patients with and without lepra reaction. A total of 65 patients were included in the study with 30 leprosy patients without reaction and 35 with lepra reaction. Serum levels of IL-17 and IL-9 were measured in these patients using direct enzyme-linked immunosorbent assay and were compared. Borderline tuberculoid (BT) leprosy with type 1 and Lepromatous (LL) leprosy with T2R patients showed significantly higher levels of IL-17 than BT and LL leprosy patients without lepra reaction, respectively. LL patients with T2R showed significantly lower levels of IL-9 than lepromatous cases without reaction. IL-9 levels were higher in BT patients with T1R as compared to BT patients without reaction but the difference was not significant. We found evidence in support of role of IL-17 in the pathogenesis of T2R, which might serve as useful serum markers for the same. IL-17 might have a role in BT leprosy with T1R. IL-9 seems to have a protective role in T2R as opposed to IL-17, working in synergism with Th1 cytokines.

Published: January 2024

Abstract

Background:
Atopic dermatitis is a chronic inflammatory skin condition common in early childhood. Acute exacerbation is frequently associated with Staphylococcus aureus colonization.

Aims and Objectives:
This study aims to explore the relationship between S. aureus skin and nasal colonization with pediatric atopic dermatitis.

Methods:
A systematic review and meta-analysis were conducted by comparing atopic dermatitis patients aged ≤18 years and nondiseased controls. A random-effects model was used to obtain the pooled prevalence and odds ratio of S. aureus colonization at eczematous skin, nonlesional skin, and nasal cavity. Subgroup analyses for colonization with methicillin-resistant S. aureus were also evaluated.

Results:
A total of 2,670 cases and 1,224 controls from 26 studies were included in the meta-analysis. S. aureus colonization at eczematous skin and nasal cavity is significantly higher in atopic dermatitis compared to control with odds ratios of 10.55 (95% confidence interval [CI]; 4.85-22.92, P < .001) and 2.38 (nasal cavity; 95% CI; 1.46-3.90, P < .001), respectively. The pooled prevalence of skin and nasal colonization were 55.0% (eczematous skin; 95% CI; 38.3-71.7), 23.3% (nonlesional skin; 95% CI; 12.6-33.9), and 56.3% (95% CI; 43.2-69.4), respectively. Methicillin-resistant S. aureus strain was obtained from the nares and eczematous skin with rates of 11.6% (95% CI; 6.5-16.7) and 8.5% (95% CI; 4.3-12.8), respectively.

Conclusion:
Children with atopic dermatitis are more prone to skin and nasal colonization by S. aureus compared to nondiseased individuals.

Abstract

Background:
Palmoplantar keratoderma (PPK) is a heterogeneous group of hereditary or acquired disorders characterised by excessive epidermal thickening of the palms and soles. Proper knowledge about the aetiology of the disease and clinico-demographic profile helps in planning management and predicting outcomes.

Aims and Objective:
To determine the prevalence of different dermatoses and describe their clinico-histological correlation in acquired palmoplantar keratoderma.

Materials and Methods:
An institution-based cross-sectional study conducted after obtaining Ethics-Committee permission and consent from participants. Patients of any age or gender presenting with acquired PPK were recruited. The calculated sample size was 67 by using the prevalence rate (p) of 22.2%, allowable error (L) of 10%, the confidence level of 95% (z = 1.96), and an infinite population size of 20,000. Patients were evaluated by taking demographic and clinical data in a pre-designed case record form, necessary laboratory investigations and histopathological examination that wereevaluated by three blinded experts. The pooled data were analysed with statistical software.

Results:
Among the 67 participants, Psoriasis was diagnosed clinically in 39 (58.2%) and histologically in 7 (10.4%), Lichen planus (LP) clinically in 16 (23.9%) and histologically in 9 (13.4%), Pityriasis rubra pilaris (PRP) in 8 (11.9%) patients clinically and 7 (10.4%) histologically and Hyperkeratotic eczema (HKE) in 4 (6%) clinically and 43 (64.2%) histopathologically. There was very poor inter-rater agreement (Kappa = 0.148, SE 0.0047, 95% CI 0.057 to 0.24). The clinico-pathological correlation was found to be agreeable in 17.9% Psoriasis, 56.2% LP and 87.5% PRP. HKE was commonly misdiagnosed as Psoriasis in 65.1% of patients.

Conclusion:
Hyperkeratotic lesions of the palm and sole often present with overlapping clinical features and a skin biopsy has to be done to aid in diagnosis.

Limitation:
Stratification of the clinical expertise of clinicians was done during the analysis.
Fresh Baked: An Overview of Newly FDA-Approved Drugs for Dermatological Usage
Authors: Sikder Bartika , Sil Abheek 
Published: January 2024

Abstract
With our better understanding of the pathogenesis of various diseases, more and more drugs and biological products are being tried and tested every day. Roughly, around 40–50 novel drugs get approved by the Food and Drug Administration (FDA) for use in the general population, making it difficult for a physician to keep track of the constant changes in therapy. This article aimed to provide a compilation of all the FDA-approved new drugs for dermatological conditions and new dermatological indications of known drugs in the recent past, especially for dermatology residents and practising dermatologists. A comprehensive analysis, based on the list of new molecular entities approved by the FDA from 2020 to 2023, as well as a thorough English language literature search from 2020 to July 2023 across multiple databases (PubMed, MEDLINE, Springer Nature, Google Scholar and Cochrane) for various keywords (alone and in combination) such as “FDA approved” OR “recent advances in therapy” OR “recent drugs” OR “novel treatment” OR “dermatology,” was performed. All data extracted were incorporated into the present compilation. A total of 33 drugs, including newly approved and newly approved indications of previously known drugs, were found. Relevant information about them has been discussed in a tabulated manner. This article provides an at a glance summarised profile of the newly FDA-approved drugs, as available in the existing literature. However, with the astonishing rate of new drugs hitting the market, more and more clinical trials are required to ensure the rational use of these agents.
Oxidative Stress in Atopic Dermatitis and Possible Biomarkers: Present and Future
Authors: Raimondo Annunziata , Serio Bianca , Lembo Serena 
Published: January 2024

Abstract
Oxidative stress is important in the pathogenesis of atopic dermatitis (AD); it can damage keratinocytes, increase dermal inflammation, and reduce skin barrier function, the hallmarks of atopic dermatitis pathogenesis. Measuring oxidative stress is possible by identifying peripheral markers, which could have a predictive value of disease severity, disease progression and response to therapy, with a potentially significant impact on patient management. Our review explored this fascinating field of research, focusing on old and new possible biomarkers that may represent an effective tool to investigate the inflammatory-oxidative axis in AD, adding clinically important information to patient care.
‘Generalised Pruritus with Prurigo-Like Lesions and Generalised Lymphadenopathy: Could be an Early Diagnostic Clue for Angioimmunoblastic T-Cell Lymphoma (AITL) and/or Histoplasmosis’
Authors: Kumar Shubham , Batra Anmol , Budania Anil , Sharma Deepak , Elhence Poonam A 
Published: January 2024

Abstract
Angioimmunoblastic T-cell lymphoma (AITL) is an uncommon systemic lymphoproliferative disorder that comprises approximately one-fifth of all mature peripheral T-cell lymphomas. A broad range of cutaneous manifestations include maculopapular, papulovesicular, erythrodermic, urticarial, plaque-like and nodular, and they are mentioned in 50% of patients and may precede systemic symptoms, which include lymphadenopathy, hepatosplenomegaly and constitutional symptoms. Histoplasmosis is a common granulomatous infection worldwide caused by Histoplasma capsulatum, a dimorphic fungus. Cutaneous manifestations are reported to occur in 10% to 25% of immunosuppressed patients with disseminated histoplasmosis. Generalised pruritus as a presenting feature is rarely described in both of these entities. We report a unique case of AITL with histoplasmosis discovered during paraclinical assessment of generalised pruritus (? neurodermatitis) with prurigo-like lesions and lymphadenopathy.
Ventricular mural thrombi – An occult occurrence?
Authors: Vaideeswar P , Srikant M 
Published: January 2024

ABSTRACT

Background:
Ventricular mural thrombi are rare occurrences and form one of the common mechanical complications of myocardial infarctions. They also occur in patients with nonischemic myocardial disorders and even in those devoid of cardiac diseases. Clinical detection often depends on the size of the thrombi.

Aim:
This study was aimed at ascertaining the etiopathogenesis of mural thrombi with a clinicopathologic correlation.

Materials and Methods:
This was a 12-year retrospective observational study reviewing the autopsy records of all cases showing ventricular mural thrombi. The location, size, morphology, and histologic appearances of the thrombi were noted. The cases, depending on the etiology, were categorized into myocardial ischemic (Group 1), myocardial nonischemic (Group 2), and non-myocardial (Group 3) causes. These features were correlated with the clinical settings.

Results:
There were 93 cases of mural thrombi with an almost equal sex distribution and a mean age of 45.9 years. The cause was ischemic heart disease in most of the patients (Group 1, 46.2%), while 21.5% and 32.3% of patients belonged to Group 2 and Group 3, respectively. Unlike the large and dominantly left ventricular thrombi seen in Group 1, the other two groups frequently had biventricular involvement, location in the intertrabecular spaces, and a high microscopic detection. Clinical diagnosis had been made in only 3.2% of patients. Thromboembolism was noted in other organs in 34.4% of the total cases.

Conclusion:
Ventricular thrombi should be ruled out in patients with evidence of systemic and/or pulmonary thromboembolism, even in those without any cardiac disorders.
Sleep apnea in end-stage renal disease patients: Impact on cardiovascular and neurological outcomes
Authors: Acree L , Waller JL , Bollag WB , Healy WJ , Baer SL , Taskar V 
Published: January 2024

ABSTRACT

Introduction:
Sleep apnea (SA) is an important comorbidity in end-stage renal disease (ESRD) patients. The association between SA and cardiac and neurological disease is known. This study investigates the relationship between SA and cardiovascular and cerebrovascular outcomes in the ESRD population.

Methods:
In a retrospective cohort study, the United States Renal Data System was queried to identify ESRD patients aged 18–100 years in whom hemodialysis had been initiated between 2005 and 2013. Diagnoses of SA and clinical comorbidities were determined from International Classification of Disease-9 codes. Demographic variables were obtained from Centers for Medicare and Medicaid Services Form-2728. Logistic regression was used to examine the association of SA with myocardial infarction (MI) or with stroke, controlling for demographic and clinical variables.

Results:
Of 858,131 subjects meeting the inclusion criteria, 587 had central SA, and 22,724 had obstructive SA. The SA cohort was younger, more likely to be male and Caucasian compared to the non-SA cohort. Patients with SA also had more tobacco and alcohol use, hypertension, heart failure, and diabetes. Central SA (aRR = 1.69, 95% CI = 1.28–2.23) and obstructive SA (aRR = 1.15, 95% CI = 1.09–1.21) were associated with an increased risk of stroke but not MI.

Conclusion:
In the ESRD population, a diagnosis of central SA or obstructive SA increased the risk of stroke, but not MI. Early identification and treatment of SA in the ESRD population may help reduce the risk of stroke in these patients.
Redefining informed consent form in cell and gene therapy trials

Published: January 2024

Abstract
Informed consent is a foundation of the ethical conduct of research involving human participants. Based on the ethical principle of respect for persons, the goal of informed consent is to ensure that participants are aware of the risks and potential benefits and make a voluntary decision about participating in clinical trial research. The extraordinary scientific advances happening globally, have demonstrated the potential of regenerative therapies in transforming the health of the nation by providing a therapeutic option for diseases that were previously considered incurable. These therapies, which include cells and gene therapy (GT) labeled as Advanced Therapeutic Medicinal Products globally, have complex mechanisms of action. Owing to their highly personalized and intricate nature of these therapies, developing the latter often presents unique challenges above and beyond those encountered for small molecule drugs. We recently looked through some cell and GT clinical trials and realized the lacunae in the informed consent form (ICF) provided by the investigators. Especially in a country like India, where the general understanding and perception of patients is limited regarding clinical trials, it is felt that any lapses in the consent process may jeopardize the informed decision-making and safety of the participants and tarnish the reputation of India globally. The present article highlights the need for appropriate patient and public education on the various aspects of cell and gene therapies and aims to address all the elements of ICF in light of the challenges associated with these innovative therapies.
Refinements of Katz–Sarnak theory for the number of points on curves over finite fields
Authors: Bergström Jonas , Howe Everett W. , Lorenzo García Elisa , Ritzenthaler Christophe 
Published: January 2024

Abstract
This paper goes beyond Katz–Sarnak theory on the distribution of curves over finite fields according to their number of rational points, theoretically, experimentally, and conjecturally. In particular, we give a formula for the limits of the moments measuring the asymmetry of this distribution for (non-hyperelliptic) curves of genus

$g\geq 3$

. The experiments point to a stronger notion of convergence than the one provided by the Katz–Sarnak framework for all curves of genus

$\geq 3$

. However, for elliptic curves and for hyperelliptic curves of every genus, we prove that this stronger convergence cannot occur.
