Approach to Mycosis Fungoides in children: Consensus-based recommendations.

BACKGROUND: Pediatric Mycosis fungoides (MF) management extrapolates from adult guidelines, despite differing clinical aspects. Recommendations are essential to address unique challenges in this distinct patient group. OBJECTIVE: This project aims to derive consensus recommendations for pediatric MF management. METHODS: Experts from pediatric dermatology, general dermatology, dermatopathology, and pediatric hematology-oncology (N = 83) were invited to contribute to consensus recommendations. The process involved 3 electronic Delphi rounds, concluding with a final consensus meeting using a modified Nominal Group Technique for unresolved items. RESULTS: Consensus included more clinical severity measures than tumor-node-metastasis-blood staging: pruritus, functional or esthetic impairment (eg, palms, soles, genitalia), quality of life impact, and psychological aspects (eg, embarrassment, anxiety, depression), plus parental anxiety. Ten recommendations were made for managing early and advanced pediatric MF. Disagreement emerged in choosing therapies beyond stage I of the disease. DISCUSSION: This multinational initiative aimed to standardize optimal pediatric MF management and successfully generated consensus recommendations. Additional work is needed for structured, prospective protocols in advanced-stage pediatric MF. LIMITATIONS: Lack of pediatric hematologists-oncologists and patients' representatives. CONCLUSION: Documentation of extended clinical severity and outcome measures is recommended. Addressing the need for structured protocols in advanced-stage pediatric MF and implementing systematic, prospective data collection is crucial.

Genotype of autosomal recessive congenital ichthyosis from a tertiary care center in India.

BACKGROUND: Autosomal recessive congenital ichthyosis (ARCI) refers to non-syndromic ichthyosis caused by mutations in one of the 13 identified genes. There are limited data on the genotype of ARCI and its phenotypic correlation from India. OBJECTIVES: The aim of this study was to characterize the genotype of ARCI among patients from the Indian subcontinent. METHODS: Twenty-eight patients clinically diagnosed as ARCI were recruited prospectively from September 2017 to June 2019 (21 months). DNA was extracted from peripheral blood and analyzed for the 13 described ARCI genes-TGM1, ABCA12, ALOX12B, ALOXE3, CERS3, CYP4F22, LIPN, NIPAL4, PNPLA1, SDR9C7, SLC27A4, SULT2B1, and CASP14 by next-generation sequencing using an in-house panel. The variants identified were confirmed by Sanger sequencing and compared with known pathogenic variants to establish pathogenicity. We also attempted to correlate the phenotype with the genotype. RESULTS: Among the 28 patients recruited (M = 17, F = 11), we identified phenotypes of congenital ichthyosiform erythroderma in 12 (42.9%), 8 with lamellar ichthyosis (28.6%), 5 with intermediate phenotype (17.9%), and 3 with bathing suit ichthyosis (10.7%). Pathogenic and likely pathogenic variants were identified in 22 (78.6%) patients, involving 7 out of the 13 known ARCI genes while 6 (21.4%) did not have pathogenic variants. These included TGM1 mutation in 6 (21.4%), ALOX12B and ALOXE3 in 4 (14.3%) each, NIPAL4 and PNPLA1 in 3 (10.7%) each, and ABCA12 and CERS3 in 1 (3.6%) patient each. Previously unknown pathogenic variants were found in 59.1 % of patients. CONCLUSIONS: Our patients with ARCI were found to have genotypes as previously described in other populations.

Two cases of CARD14-associated papulosquamous eruption from India.

Identification of CARD14-associated papulosquamous eruption (CAPE) is important as it helps in determining prognosis and management of those affected. We report two siblings with genetically confirmed CAPE presenting with treatment-resistant erythroderma in one patient and patterned psoriatic plaques with facial predominance in the other.

Pilomatricomas and café au lait macules as herald signs of constitutional mismatch repair deficiency (CMMRD) syndrome-A case report.

Constitutional mismatch repair deficiency (CMMRD) syndrome results from bi-allelic mutations in DNA mismatch repair genes-MLH1, MSH2, MSH6, or PMS2. We present two siblings with CMMRD having p.Arg802Ter (c.2404C >T) homozygous mutations in PMS2 exon 14 with typical cutaneous features. This case report highlights the role of the dermatologist in early diagnosis of this condition.

Satoyoshi syndrome-A case report from India.

Satoyoshi syndrome was first reported in Japan in 1967. It is a rare multisystem disorder of presumed autoimmune etiology that is characterized by alopecia, intermittent painful muscle spasms, diarrhea, and antinuclear antibody positivity. We report an 11-year-old girl with Satoyoshi syndrome who presented to the dermatology department for treatment of alopecia universalis. We present this case to emphasize the importance of recognizing Satoyoshi syndrome, which could go unnoticed if not suspected.

Hydroa vacciniforme-like lymphoma: a case report from India.

We report a 14-year-old Indian boy who presented with a history of weight loss, fever, facial edema, and a relapsing papulovesicular eruption on the face and limbs for 1 year. Histopathology of the skin showed dense lymphoid infiltrate from dermis to subcutaneous fat. Immunohistochemistry of this lymphoid infiltrate was CD3, CD8, CD56, CD57, Granzyme B, TIA, and Epstein Barr virus LMP1. The histopathology and immunohistochemistry were consistent with the diagnosis of hydroa vacciniforme-like T-cell lymphoma. The child responded remarkably to oral steroids but relapsed on tapering doses. CHOP (Cyclophosphamide, Adriamycin, Vincristine, and Prednisolone) chemotherapy was initiated in view of systemic involvement to which he showed some response, however, the disease relapsed again. He then had a rapidly progressive disease and ultimately succumbed to his illness. This is the first case of hydroa vacciniforme-like T-cell lymphoma being reported from this subcontinent.

Clinical profile of childhood-onset psoriasis and prevalence of HLA-Cw6: a hospital-based study from India.

BACKGROUND: Childhood-onset psoriasis (COP), a distinct clinical entity, may be associated with HLA-Cw6 positivity and metabolic and cardiovascular complications. There is some evidence that HLA-Cw6 positivity is associated with more extensive or severe disease and that positivity is lower in Asian patients than in Caucasians. We describe the clinical profile, prevalence of the HLA-Cw6 allele, metabolic syndrome (MetS) and vitamin D deficiency in Indian patients with COP. METHODS: In this cross-sectional hospital-based study over 15 months (June 2010-August 2011), 108 consecutive patients with disease onset ≤16 years were enrolled. Demographic, clinical and laboratory data were collected. Patients were categorised as children with COP (CCOP; n=69) or adults with COP (ACOP; n=39). Disease severity was assessed using body surface area (BSA) involved and Psoriasis Area and Severity Index (PASI) score. RESULTS: The most common morphological type was chronic plaque psoriasis; follicular psoriasis was seen only in children. Adults with disease onset in childhood, when compared with CCOP, had later disease onset (11.0±4.0 vs 6.9±3.8 (mean±SD) years; p<0.0001) of greater severity (p=0.021) based on BSA involved. PASI scores were, however, similar in ACOP and CCOP. Body mass index was not associated with disease severity. Of the 83 who underwent HLA-C typing, 46 (55.4%) were positive; positivity was associated with guttate lesions (p=0.031), scalp involvement (p=0.004), greater BSA involvement (p=0.002) and higher PASI scores (p=0.013). Vitamin D deficiency, obesity and MetS were present in 77.4%, 10.7% and 14.5% of patients, respectively. CONCLUSIONS: Among Indian patients, CCOP have earlier disease onset than ACOP. HLA-Cw6 was associated with guttate psoriasis, scalp involvement and disease severity. Vitamin D deficiency was common.

Cytomegalovirus reactivation in drug induced hypersensitivity syndrome.

Drug induced hypersensitivity syndrome has been reported to a variety of drugs. Reactivation of herpes viruses is associated with relapse of symptoms even as late as five weeks after stopping the inciting drug. We report here a case of drug hypersensitivity with CMV reactivation which was treated successfully.

Aligning patient values and code status: Choice of Diction's Effect (CODE) study.

BACKGROUND: Decisions regarding resuscitation after cardiac arrest are critical from ethical, patient satisfaction, outcome, and healthcare cost standpoints. Physician-reported discussion barriers include topic discomfort, fear of time commitment, and difficulty articulating end-of-life concepts. The influence of language used in these discussions has not been tested. This study explored whether utilizing the alternate term "allow (a) natural death" changed code status decisions in hospitalized patients versus "do not resuscitate" (DNR). METHODS: All patients age 65 and over admitted to a general medicine hospital teaching service were screened (English-speaking, not ICU-level care, no active psychiatric illness, no substance misuse, no active DNR). Participants were randomized to resuscitation discussions with either DNR or "allow natural death" as the "no code" phrasing. Outcomes included patient resuscitation decision, satisfaction with and duration of the conversation, and decision correlation with illness severity and predicted resuscitation success. RESULTS: 102 participants were randomized to the "allow natural death" (N = 49) or DNR (N = 53) arms. The overall "no code" rate for our sample of hospitalized general medicine inpatients age >65 was 16.7%, with 13% in the DNR and 20.4% in the "allow natural death" arms (p = 0.35). Discussion length was similar in the DNR and "allow natural death" arms (3.9 + 3.2 vs. 4.9 + 3.9 minutes), and not significantly different (p = 0.53). Over 90% of participants were highly satisfied with their code status decision, without difference between arms (p = 0.49). CONCLUSIONS: Participants' code status discussions did not differ in "no code" rate between "allow natural death" and DNR arms but were short in length and had high patient satisfaction. Previously reported code status discussion barriers were not encountered. It is appropriate to screen code status in all hospitalized patients regardless of phrasing used.

Dermatological manifestations and relationship to outcomes of patients admitted to a medical intensive care unit: a study from a tertiary care hospital in India.

AIM: To determine the prevalence of dermatological manifestations in intensive care unit (ICU) patients and assess its impact on outcomes. METHODS: This was a prospective cohort study of 1013 ICU patients admitted between December 2009 and April 2011. Patients were categorised following an initial screening (within 48 h) and subsequent daily review as those with dermatological manifestations in association with multisystem disorder (category 1), occurring due to treatment or critical illness (category 2), coincidental lesions (category 3) or primary dermatological conditions needing intensive care (category 4). Outcomes included mortality, duration of ventilation and hospitalisation. Factors associated with mortality were explored using univariate and multivariate analyses. RESULTS: Dermatological manifestations were observed in 427 (42.2%) patients, predominantly of categories 1 (n=159) and 2 (n=160). Common aetiologies were infections (39.3%) and mechanical, thermal or physical injuries (32.8%). Primary dermatological conditions (n=33) included 21 patients with cutaneous infections, 3 with angioedema, 2 each with pemphigus, toxic epidermal necrolysis and psoriasis, and 1 each with Stevens-Johnson syndrome, drug hypersensitivity syndrome and crusted scabies. The presence of cutaneous lesions increased mortality risk (OR 1.56, 95% CI 1.20 to 2.03) and significantly (p<0.001) prolonged ventilation and hospitalisation. Mortality was higher (p<0.001) in patients in categories 4 (65.6%) and 2 (57.5%) compared to those without manifestations (35.5%). After adjusting for age, Acute Physiology And Chronic Health Evaluation II (APACHE-II) score, ventilation and dialysis, the association between dermatological manifestations and mortality was insignificant (OR 1.37, 95% CI 0.97 to 1.95). CONCLUSIONS: Dermatological manifestations are common in ICU patients. Their presence may impact mortality and duration of ventilation and hospitalisation.

Mindin (SPON2) Is Essential for Cutaneous Fibrogenesis in a Mouse Model of Systemic Sclerosis.

Systemic sclerosis is a fibrotic disease that initiates in the skin and progresses to internal organs, leading to a poor prognosis. Unraveling the etiology of a chronic, multifactorial disease such as systemic sclerosis has been aided by various animal models that recapitulate certain aspects of the human pathology. We found that the transcription factor SNAI1 is overexpressed in the epidermis of patients with systemic sclerosis, and a transgenic mouse recapitulating this expression pattern is sufficient to induce many clinical features of the human disease. Using this mouse model as a discovery platform, we have uncovered a critical role for the matricellular protein Mindin (SPON2) in fibrogenesis. Mindin is produced by SNAI1 transgenic skin keratinocytes and aids fibrogenesis by inducing early inflammatory cytokine production and collagen secretion in resident dermal fibroblasts. Given the dispensability of Mindin in normal tissue physiology, targeting this protein holds promise as an effective therapy for fibrosis.

Pediatric onset keratosis lichenoides chronica: a case report.

Keratosis lichenoides chronica (KLC) is an acquired keratinization disorder that is rare in childhood. We report a case of sporadic pediatric-onset KLC with seborrheic dermatitis-like lesions on the forehead, papules in a retiform pattern in the axillae and mons pubis, and eye and oral mucosal involvement,with additional features of premature canities and a transient photosensitive eruption.

Cutaneous cholesterol embolization syndrome: A case report.

An 81-year-old woman with chronic kidney disease, systemic hypertension, and a large infra-renal abdominal aortic aneurysm, developed bilateral calf muscle pain, altered sensorium, and deterioration of renal function following endovascular aneurysmal repair. On the third post-operative day she developed symmetrical purpuric macules with erythematous margins on the gluteal region and bluish reticulated patches on the soles and tips of toes. This was followed by melena development on the seventh post-operative day. Histology of the skin confirmed the diagnosis of cutaneous cholesterol embolization syndrome (CES). She was treated with hemodialysis and supportive management and she recovered.

Chronic Mucocutaneous Candidiasis due to Signal Transducer and Activator of Transcription 1 (STAT 1) Mutation in an Indian Patient - A Case Report.

Chronic mucocutaneous candidiasis (CMC) is a primary immunodeficiency due to defect in various genes leading to an increase in susceptibility to skin and mucosal infection. Mutation in signal transducer and activator of transcription 1 (STAT 1) gene being the most common cause of CMC can lead to increased risk of infections, multisystem abnormalities, and malignancy. We describe a 27 year old Indian woman with clinical features of CMC including esophageal stenosis, gangrene of the finger, endocrinological and immunological abnormalities and STAT1 mutation (p.Leu407Val). She was treated with antifungals which led to symptomatic improvement.
