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.

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.

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.

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.

Clinicopathological Profile of Childhood Onset Cutaneous Mastocytosis from a Tertiary Care Center in South India.

BACKGROUND: Mastocytosis is characterized by clonal proliferation of mast cells in various organs and can have isolated cutaneous or systemic involvement. Childhood-onset mastocytosis (COM) is usually cutaneous and regresses spontaneously, while adult-onset mastocytosis (AOM) is often persistent with systemic involvement. There is limited data on COM from India. OBJECTIVE: To elucidate the clinicopathological profile of COM. METHODS: We conducted a retrospective chart review of all the patients with histologically proven COM (≤16 years), presenting over 11 years (January 2009 to December 2019) to the Dermatology Department. We compiled the demographic data, clinical characteristics (morphology, extent, distribution), laboratory investigations, histopathology findings, imaging (ultrasound abdomen), c-KIT mutation results, where available, and other associated abnormalities, and grouped them according to the WHO classification for mastocytosis. RESULTS: Among the 66 patients with COM (M: F-1.6:1), 89.4% had onset before 2 years of age. The subtypes were: maculopapular cutaneous mastocytosis (MPCM: 44, 66.7%); mastocytoma of the skin (MOS: 19, 28.8%); diffuse cutaneous mastocytosis (DCM: 2, 3%) and indolent systemic mastocytosis (ISM: 1, 1.5%). Blistering was observed in 29 (43.9%) and Darier sign was elicited in 47 (71.2%) patients. Serum tryptase was elevated in 9/21 (42.9%) patients, but none had systemic mastocytosis. Three patients had c-KIT mutations (two in exon 8 and one in exon 17). Most patients were managed symptomatically and the patient with ISM improved with imatinib. CONCLUSION: MPCM is the most common variant of COM and most patients had a disease onset before 2 years. Overall, COM had a good prognosis with rare systemic involvement, mitigating the need for extensive evaluation routinely in children.

Paraneoplastic Autoimmune Multiorgan Syndrome: A Retrospective Study from a Tertiary Care Center in South India.

BACKGROUND: Paraneoplastic autoimmune multiorgan syndrome (PAMS), first described as paraneoplastic pemphigus (PNP) is a heterogeneous autoimmune syndrome with a diverse spectrum of clinical and immunopathological features associated with an internal neoplasm. MATERIALS AND METHODS: The details of the patients diagnosed with PAMS/PNP from an Indian tertiary center between January 2010 to December 2019 were retrieved from the hospital database. The clinical manifestations, histopathological features, immunofluorescence findings, and other relevant clinical details were obtained. RESULTS: There were eight patients (4 males, 4 females) with PAMS, age ranging from 8 to 46 years (mean 31 years), of whom two were 8-year-old children. The mucocutaneous manifestations were polymorphic and all had recalcitrant oral mucosal involvement. The most common mucosal presentation was pemphigus-like (5/8), and the cutaneous presentation was lichen planus-like (5/8). Castleman's disease (5/8) was the commonest neoplasm followed by thymoma (2/8). Interface dermatitis was seen in all biopsies and three different patterns of direct immunofluorescence were seen, which were intercellular "fish-net" fluorescence in the epidermis (2/8), granular/linear deposition along the basement membrane (4/8) and a combination of both patterns (1/8). Indirect immunofluorescence done on rat bladder in 3 patients showed intercellular "fish-net" fluorescence. Desmoglein levels were not elevated in any of our patients. The follow-up period ranged from 1 to 112.5 months (mean, 23.6 months) with a mortality rate of 12.5%. CONCLUSION: In our study, Castleman's disease was the most common associated malignancy, and the mucocutaneous and histopathological findings were heterogeneous. Timely diagnosis and early intervention improved the outcome in our patients.

Phenotypic variability of a TREX1 variant in Aicardi-Goutieres type 1 patients from the Indian subcontinent.

Aicardi-Goutieres Syndrome (AGS) is a heterogeneous genetic syndrome, manifesting early as encephalopathy and is associated with abnormal neurologic findings, hepatosplenomegaly, elevated liver enzymes, thrombocytopenia and intracranial calcification. The most severe neonatal type, AGS1, is caused by biallelic disease-causing variants in TREX1. In this study, we describe four patients with TREX1-related AGS1 whose phenotype overlaps with intra-uterine infections and neonatal lupus. Exome sequencing identified a previously reported TREX1 variant, c.223dup (NM_016381.5; p. Glu75GlyfsTer82) in all the four patients belonging to the Indian subcontinent. The functional consequence of the disease-causing variant was predicted by using a new combination of bioinformatics softwares. The recurrence of this pathogenic variant indicates a possible founder effect in TREX1 for AGS1 in this population. The phenotypic variability in those with this founder mutation can mimic intrauterine infections and neonatal lupus, thereby leading to misdiagnosis warranting a targeted genetic testing approach to be a part of the diagnostic workup to obtain a definite, early and cost-effective diagnosis in patients from Indian subcontinent with early onset encephalopathy.

The Diagnostic Value of Congenital and Nevoid Cutaneous Lesions Associated with Autism Spectrum Disorders in Indian Children- A Case-Control Study.

BACKGROUND AND AIMS: Cutaneous lesions are the defining features of several neurocutaneous syndromes like neurofibromatosis1(NF1), tuberous sclerosis complex (TSC), and Sturge Weber syndrome to name a few. With this background, we explored the possibility of identifying congenital and nevoid cutaneous markers that may help in the early recognition of autism spectrum disorders (ASD) in Indian children. The objective of this study was to measure the strength of association between congenital and nevoid cutaneous lesions and ASD among Indian children. METHODS: A case-control study was conducted from January 2018 to June 2018. 132 children (18 months-16 years of age) with ASD and equal number of age and sex-matched children without autism were studied. Diagnosis of ASD was based on DSM-5 criteria. All the children were examined for cutaneous lesions with special attention to nevoid and congenital conditions. The strength of association was measured using the diagnostic odds ratio (OR). RESULTS: The prevalence of congenital and nevoid lesions were higher in ASD group (OR = 3.12, P = 0.0001). Among them, pigmentary mosaicism of hyperpigmented type (OR = 2.76, P = 0.02) and café-au-lait macules (CALMs) (OR = 2.40, P = 0.001) were the most prevalent with hyperpigmented pigmentary mosaicism showing a higher association with autism. Atypical CALMs (OR = 2, P = 0.09) were also more prevalent in the ASD group though not statistically significant. CONCLUSION: The presence of hyperpigmented pigmentary mosaicism and CALMs warrant closer surveillance by the caregivers and physicians for evolving features of autism. Larger multicentric studies are required to validate these findings.

The Role of Frozen Section in the Rapid Diagnosis of Severe Cutaneous Adverse Drug Reactions.

CONTEXT: Early diagnosis is the mainstay in the management of severe cutaneous adverse reactions (SCARs) to drugs. AIMS: To study the role of frozen section in the rapid diagnosis of SCARs and the impact on outcome of the affected patients. SETTINGS AND DESIGN: A single-blind, hospital-based study was conducted from December 2014-July 2016. METHODS AND MATERIAL: We biopsied 32 adults with SCARs diagnosed by clinical features and standard criteria. The histopathological features seen on frozen sections were compared to that of paraffin blocks. The impact of rapid diagnosis on the clinical outcome was studied in toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome (SJS), drug rash with eosinophilia and systemic symptoms (DRESS) and acute generalized exanthematous pustulosis (AGEP). STATISTICAL ANALYSIS: Z test was used to compare two proportions. Kappa statistic, sensitivity, specificity, positive predictive value, and negative predictive value of the frozen section diagnosis were calculated in TEN/SJS and DRESS using MedCalc software. RESULTS: Frozen and paraffin sections were done in TEN/SJS spectrum (13), DRESS (17), and AGEP (2). The sensitivity, specificity and kappa values for frozen section diagnosis in SJS/TEN and DRESS were 91.7%, 95%, 0.867 and 94.4%, 100%, 0.937 respectively. The concordance between frozen and paraffin section diagnosis was 100% in TEN, SJS, DRESS and AGEP. All the 6 patients with TEN and 2 with AGEP survived. Taking the worst-case scenario, the mortality in SJS was 28.6%. The mortality among patients with DRESS was 11.8%. CONCLUSIONS: Frozen section helps in the rapid diagnosis and early treatment of SCARs and differentiates it from diseases that mimic it.

Clinical Profile of Overgrowth Syndromes Consistent with PROS (PIK3CA-Related Overgrowth Syndromes)-A Case Series.

CONTEXT: PIK3CA-related overgrowth syndrome (PROS) is characterized by focal and disproportionate growth of acral body structures in a mosaic pattern with varied phenotypes. Clinical diagnostic criteria are available and testing of the mutation is recommended for diagnosis. Cutaneous features described in these conditions include epidermal nevi and vascular malformations which form part of the diagnostic criteria. AIMS: To detail the clinical profile of patients with presumptive PROS. SETTINGS AND DESIGN: We conducted a retrospective study of 15 patients with focal overgrowth of the extremities or macrocephaly who presented to the department of dermatology at a tertiary care hospital in South India. SUBJECTS AND METHODS: Data were collected through electronic medical records from July 2012 to April 2018 over 70 months. The criterion proposed by Keppler-Noreuil et al. was used for classifying them as presumptive PROS in the absence of genetic studies. STATISTICAL ANALYSIS USED: Descriptive analysis. RESULTS: There were nine males and six females; mean age of 12.10 years (range: 8 months to 73 years) with clinical features consistent with PROS. There was a higher frequency of vascular malformations (9/15, 60%) and of epidermal nevi (7/15, 46.6%) than that reported in the literature. Unusual features included focal acrochordons, blaschkoid hypopigmentation and linear papillomatous growths in the oral mucosa. CONCLUSIONS: This study provides data on the clinical features of patients with PROS from the Indian subcontinent. In resource-poor settings, clinical criteria may be adequate for diagnosis due to restricted accessibility of technically challenging diagnostic tests.

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.

Peripheral Arteriovenous Malformations-A Case Series.

CONTEXT: Arteriovenous malformations (AVMs) are aggressive vascular malformations that often result in significant morbidity. Patients may present to a dermatologist due to associated skin changes. Early diagnosis is important as treatment is available to halt their progression toward irreversible destruction of adjacent tissues. AIMS: To study the clinical profile of peripheral AVMs presenting to the dermatologist and to provide a diagnostic algorithm. SETTINGS AND DESIGN: A retrospective study of patients of all age groups with peripheral AVMs who presented to the Department of Dermatology at a tertiary care hospital in India was performed. Syndromic forms were also included. SUBJECTS AND METHODS: We conducted a search of patients with peripheral AVMs, which were seen over a period of 51 months, i.e., from July 2014 to September 2018, from electronic medical records and reviewed their clinical details. STATISTICAL ANALYSIS USED: Descriptive statistics such as frequency, mean, and median were computed. RESULTS: We report a series of 13 patients with peripheral AVMs, which constituted 6.7% (13/193) of all vascular malformations during this period. Of these, 8.3% (1/12) belonged to Schobinger's stage 1, 41.7% (5/12) to stage 2, 50% (6/12) to stage 3, and one with subcutaneous involvement devoid of cutaneous changes. The most common location was the extremities, which was seen in 53.8% (7/13). Syndromic association was present in 46.2% (6/13). Management included embolization, surgery, and medical treatment. CONCLUSIONS: The proportion of peripheral AVMs out of all vascular malformations was similar to reported studies. The extremities were more frequently involved as compared to the head and neck. The diagnostic algorithm provided will help us to optimize investigations and direct early management.

Dowling-Degos Disease with Hidradenitis Suppurativa and Inflammatory Arthritis in Two Generations.

Dowling-Degos disease (DDD) is a rare autosomal dominant genodermatosis characterized by reticulate brown-to-black pigmentation of the flexures, pitted perioral acneiform scars, and comedo-like follicular papules on the flexures. The diagnosis is based on characteristic clinical and histopathological features. DDD has been found to occur in association with hidradenitis suppurativa (HS), arthritis, epidermoid cysts, keratoacanthomas, and squamous cell carcinoma. To date, there is only one report of DDD associated with HS and polyarticular arthritis.

Update on Management of Morphea (Localized Scleroderma) in Children.

Juvenile localized scleroderma (morphea) is the predominant scleroderma in childhood which affects the skin and may extend to the underlying fascia, muscle, joints and bone. The assessment of activity and damage can be done with a validated instrument like LoSCAT. Disease classified as "low severity" which includes superficial plaque morphea can be treated with topical mid potent- potent steroids, tacrolimus, calcipotriol or imiquimod in combination with phototherapy. Methotrexate is recommended for linear, deep and generalized morphea. Steroids are effective in the early inflammatory stage and used in combination with methotrexate. Methotrexate is continued for at least 12 months after adequate response is achieved. Mycophenolate mofetil is given in cases where methotrexate is contraindicated or for those who do not respond to methotrexate. There are also reports of improvement of disease with ciclosporine and hydroxychloroquine. In severe cases, recalcitrant to standard therapy there may be a role for biologics, JAK inhibitors, and IVIG. Supportive measures like physiotherapy and psychiatric counseling are also important in the management of morphea. Orthopedic surgery and other measures like autologous fat transfer may be advocated once the disease is inactive.

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.

Pediatric Cutaneous Emergencies and their Outcome: Study from a Tertiary Care Center in South India.

BACKGROUND: Skin problems are commonly encountered in the pediatric emergency department (PED). Although there are a few studies on the prevalence and spectrum of skin conditions in children attending the PED, only limited information is available on the outcome of the children with skin-related ailments requiring hospitalization. AIM: To study the clinical profile of skin manifestations in children presenting to the PED over a period of one year and assess the impact of skin lesions on the clinical outcome. MATERIALS AND METHODS: All children <16 years of age attending the PED were screened and children with skin lesions were referred to the dermatologist for further evaluation, and those admitted were followed up until discharge. Children with skin lesions were categorized into seven subsets based on their diagnosis. Outcomes evaluated were duration of hospital stay, associated systemic inflammatory response syndrome (SIRS), and mortality. RESULTS: Of the 24,324 patients screened, 203 (0.83%) had skin lesions, of whom 158 (77.83%) were discharged from the PED. Forty five (22.16%) patients required admission of whom 2 (0.99%) died. Inflammatory disorders were the most common, 102 (50.24%), followed by infections in 91 (44.82%) patients. Among the hospitalized patients, 25 (55.6%) had SIRS, which included infections in 14 (56%), vasculitis in 5 (20%), and urticaria in 3 (12%) patients. Two patients with SIRS died and the causes were purpura fulminans and febrile exanthem of probable viral etiology. CONCLUSION: Our study highlights the spectrum of pediatric cutaneous emergencies and their outcome. A subset of patients can present with severe skin ailments and SIRS in whom early diagnosis and prompt treatment can impact the outcome.
