Maskne: Its relationship to skin microbiome and response to treatment

Mask-wearing during the ongoing COVID-19 pandemic has been associated with an increased occurrence of a form of acne mechanica, popularly termed 'maskne. However, our understanding of this entity is limited. Hence we aimed to study the role of changes in the skin microbiome in mask induced acne and its response to standard acne treatment regimens. This was a prospective observational study. Adult patients having new-onset of lesions suggestive of acne within 6 weeks of regularly wearing mask or exacerbation of pre-existing acne were recruited. Disease severity was assessed using the 'Global Acne Severity Grading System (GAGS). Sample collection was done from pustules or comedones. Treatment was given according to American Academy of Dermatology Guidelines and follow up was done till 12 weeks. Data was entered and analyzed using Statistical Package for Social Sciences (SPSS) v.25. Total 50 patients were recruited in the study. 56% patients were female and 44% were male. 60% patients had a history of similar lesions in the past. 56% patients used surgical mask, 34 % used N-95 mask and 18 % used cloth mask. The average duration of use for mask per day was 6.78 +/- 2.65. Cheeks were the most commonly involved site and 62% of patients had mild GAGS. The severity of acne was significantly higher in patients using N-95 mask ( p<0.05) but not associated with duration of mask use, history of mask re-use and use of moisturizers. 70% cases did not require systemic treatment. KOH was negative in all cases. Gram stain showed gram positive cocci and rods in 22% and 14 % cases respectively. Aerobic culture showed Staphylococcus aureus growth in 30% cases and Anaerobic culture showed Cutibacterum acnes growth in 20% cases. In our study we found that maskne presented with a milder variant of acne which in majority of cases responded well to topical treatment standardized for acne vulgaris and had a microbiome profile similar to acne vulgaris.Copyright © 2023

Allergic contact dermatitis to the elastic bands of an N95 mask

Case report Introduction: In the wake of the COVID-19 pandemic, occupational contact dermatitis related to the use of personal protective equipment (PPE) has become increasingly prevalent. While most cases are irritant in nature, allergic contact dermatitis (ACD) remains an important cause of occupational dermatitis. We report a case of ACD to rubber accelerators in the elastic bands of an N95 mask. Informed consent was obtained from the patient for this report. Case Report: A 27-year-old healthcare worker presented with a progressive pruritic eruption over her face and neck, 1 week after she began wearing N95 masks at work. She had only worn disposable surgical masks. She had no medical history apart from hand dermatitis, which was well controlled with topical medications. Examination revealed linear eczematous plaques along her lateral cheeks and posterior neck, corresponding to contact areas between the mask bands and her skin. Patch tests revealed a positive reaction to several rubber accelerators, including Thimerosal, 2-Mercaptobenzothiazole (MBT), and Methylisothiazolinone. We performed another patch test to several N95 mask straps, to which the patient developed an eczematous reaction to the elastic bands of 2 N95 mask types with elastic bands. Clarification with the manufacturer confirmed the use of rubber accelerators similar in properties to MBT in the production of these masks. A diagnosis of allergic contact dermatitis to rubber accelerator was made. The patient's dermatitis resolved with topical corticosteroids and the avoidance of N95 masks with elastic bands. Discussion and Conclusion(s): The use of facial PPE such as masks is a recognised cause of occupational dermatitis among healthcare workers. A variety of dermatoses are associated with the use of facial PPE, with contact dermatitis being the most common. However, while the majority of contact dermatitis are irritant in nature, ACD remains an important and preventable cause of occupational dermatitis. Commonly implicated allergens associated with mask use include preservatives and adhesives used in their production, as well as metals in the nose clip. Although less common, mask elastic bands have also been reported to be a potential source of ACD, with rubber accelerators being identified as potential allergens. However, there is often a lack of declaration of such chemicals used in the production of PPE. Given the need for continued use in the occupational setting, early identification and avoidance of allergens are key. Failure to do so may result in the progression of skin lesions, ultimately affecting the patients' quality of life and work performance. With the ubiquitous use of masks in the current climate, we wish to highlight the need for greater awareness of rubber accelerators as potential allergens, and their presence in the elastic bands of frequently used PPE.

Unilateral multiple facial angiofibromas as a solitary manifestation of tuberous sclerosis

We describe the case of a 12-year-old boy who presented via teledermatology with a 5-6-year history of multiple lesions on the right side of his face. They were unchanged since their initial appearance at 6 years of age but were slowly increasing in number across his right cheek and extending onto the chin. Although the lesions were asymptomatic, growing older had made him feel increasingly self-conscious. He was otherwise fit and well, and attended mainstream school, with no past medical history or family history of note. Perinatal and birth history were also uneventful. On examination, he had multiple, 1-2-mm, erythematous papules confined to the right cheek and right chin. Dermoscopy showed an unusual pattern of vessels with nonspecific globules in between. The rest of the skin, hair and nails were entirely normal in appearance. There were no systemic symptoms and a detailed general and systemic examination, as well as radiological imaging, did not reveal any abnormality. An excisional biopsy was taken of one of the lesions, with histological examination demonstrating focal superficial telangiectasia with associated bland round-tospindle cell proliferation, appearances most in keeping with an angiofibroma. This correlated well clinically, apart from unilateral facial angiofibromas being the solitary finding in our patient. Facial angiofibromas - also called adenoma sebaceum - are well described as part of the cutaneous manifestations of tuberous sclerosis (TSC). Classically, these appear as a facial rash in the form of small pink or red spots across the cheeks and nose in a butterfly distribution, at between 3 and 10 years of age, increasing in size and number until adolescence. TSC is an autosomal dominant disorder with defective mammalian target of rapamycin (mTOR) signalling, characterized by hamartomas in many organs, particularly the skin, central nervous system, renal and cardiovascular systems. The clinical presentation is variable, with other well known and frequently reported cutaneous findings such as shagreen patches, ash-leaf macules and periungual fibromas. Unilateral multiple facial angiofibromas in the absence of other cutaneous or systemic manifestations of TSC - as in our patient - are rare, with only 13 reported cases. These may form part of the clinical spectrum of TSC as a probable consequence of cutaneous mosaicism in which a postzygotic genetic mutation has occurred. Our patient was referred for genetic testing, but this has been delayed as a result of the COVID-19 pandemic. Topical sirolimus 1% - an mTOR inhibitor - has been used with good effect for facial angiofibromas, and our patient also responded well to this.

First reported case of parvovirus triggering painful widespread livedoid vasculopathy: another virus causing hypercoagulability?

Livedoid vasculopathy (LV) is a noninflammatory thrombotic disease caused by occlusion of dermal small vessels associated with systemic autoimmune disorders and coagulopathies. However, LV is often reported as being 'idiopathic', despite extensive investigation. We report a case of severe LV in an otherwise healthy 27-year-old woman, associated with parvovirus infection. The patient presented with a short history of a livedoid rash initially covering her torso, which spread to acral sites. Burning pains in the lower limb caused reduced mobility;systemically, she remained well and stable throughout. Examination revealed generalized acral skin pallor, livedoid patches of violet erythema and purpura with deep serpiginous ulcerations over extensor aspects of upper and lower limbs with a more broken/racemosa nonulcerated livedoid appearance on the trunk. On admission a transaminitisareas continued to ulcerate. Codeine was present with a creatine kinase of 1569 U L.1, but other blood test results were unremarkable including erythrocyte sedimentation rate, complement, cryoglobulins, antinuclear antibodies, antineutrophil cytoplasmic antibodies, extractable nuclear antigen, rheumatoid factor, myositis screen, antiphospholipid screen and thrombophilia screen. Parvovirus IgG and IgM were both positive and tested for, as the patient's young daughter had recently been diagnosed with 'slapped cheek disease'. Magnetic resonance imaging of the thighs showed a diffuse mild myositis;electromyography, nerve-conduction studies, barium swallow and computed tomography of the chest, abdomen and pelvis were all normal. An incisional skin biopsy was performed, which revealed a blood vessel with organizing (Solimani F, Mansour Y, Didona D et al. Development of severe pemphigus vulgaris following SARS-CoV-2 vaccination with BNT162b2. J Eur Acad Dermatol Venereol 2021;35: e649- 51) have been reported. The main proposed mechanisms for AstraZeneca vaccine-induced pemphigus could be a hyperimmune reaction in genetically predisposed individuals, with eventual formation of anti-desmoglein antibodies. An alternative hypothesis is that vaccine components could act as foreign antigens resulting in a cross-reaction with pemphigus antigens. The close association of COVID-19 vaccination with the acute onset of pemphigus in our patient, as well as exacerbations after subsequent vaccine administration, is more than coincidental. Considering the recent pandemic with COVID-19 and the widespread administration of the COVID-19 vaccine, continued observation and documentation of true adverse events is essential.

Facial herpes zoster associated with disease reactivation in a patient with multiple sclerosis under dimethyl fumarate treatment

Background: Dimethyl fumarate (DMF) is an approved treatment for multiple sclerosis (MS). Due to its efficacy and safety profile, DMF is the most prescribed oral medication for relapsing remitting (RR) MS. Given the long-term course of treatment with DMF in MS, continuous surveillance of opportunistic infections is fundamental. Case presentation: We report the occurrence of facial herpes zoster (HZ) associated with MS disease reactivation in a person with RRMS after 6 years of DMF therapy. Case report: A 44-year-old woman with RRMS developed right temple pain and blisters over the right cheek, suggestive of facial HZ. A normal lymphocyte count with however relatively lower proportions of CD8+ T cells and higher percentages of natural killer cells were detected in blood. The patient failed oral treatment and required hospitalization for intravenous acyclovir. She eventually developed symptoms of an MS exacerbation featured by lower extremities weakness and urinary retention. Conclusion(s): Our case highlights the importance of counseling patients on the possibility of HZ reactivation even in the setting of a normal lymphocyte count, the risk of MS exacerbation possibly associated with HZ occurrence and the importance of timely vaccination.Copyright © 2022

Popper's Dermatitis: A Unique Form of Contact Dermatitis In the MSM Community

Rationale: Men who have sex with men have different contact allergen exposures compared to men who have sex with women due to cultural differences in the LGBTQ+ community. Poppers, a common name for volatile alkyl nitrates, are used more frequently in the MSM community as recreational inhalants. We aimed to identify common anatomic sites and contact allergens associated with popper's dermatitis in the MSM community. Method(s): Covidence, Embase, MEDLINE, PubMed, Web of Science, and Google Scholar were searched to identify relevant articles studying allergic contact dermatitis associated with poppers in the MSM population. Search terms included 'allergic' or 'contact dermatitis' or 'patch testing' or "poppers" or 'Men who have sex with men'. Date, geographical or language restrictions were not used. No exclusion criteria was used. Result(s): : Common allergens associated with popper's dermatitis in the MSM community included amyl nitrate (N=7), isobutyl nitrate (N=3), isopropyl nitrate (N=2), and fragrance mix (N=5). Common anatomic sites included perioral regions (N=3), chest (N=2), nasal orifices (N=3), cheeks (N=5), penis (N=1), and lateral thigh (N=1). Conclusion(s): Sexual orientation is a relevant factor for dermatologists/allergists to consider, as the standard patch test series does not include common allergens associated with popper's dermatitis which disproportionally affects the MSM community. Our community needs to include gender and sexuality demographics when collecting patch test data.Copyright © 2022

Trisomy 18p detected in DNA from saliva but absent in DNA from blood

Molecular diagnostic testing using DNA from saliva specimens markedly increased recently due to the ease of sample collection, compared to peripheral blood, during the COVID-19 pandemic. Published literature suggests that DNA from saliva is primarily composed of epithelial cells (70-90%), with the remainder being primarily leukocytes (10-30%). Here, we describe a case followed by our clinicians since 2007 characterized by developmental delay, autism, a somewhat coarse face with full cheeks, up-slanting palpebral fissures, thin corpus callosum, and a full-scale IQ of 60. This patient had an extensive work-up including high-resolution blood chromosome analysis, FISH for 22q microdeletion, three separate microarrays (various platforms), FMR1 molecular analysis, urine oligosaccharides analysis, an autism gene panel by NGS, and whole-exome sequencing, none of which identified a satisfactory diagnosis. These tests were performed on two peripheral blood samples collected at different times. Recently, a new microarray was ordered on a saliva sample from this patient, and an apparently non-mosaic gain of 18p was detected. The possibility of a sample swap was eliminated by comparing the SNP genotype of the saliva sample to the previously tested blood sample. The limit of detection for mosaicism in genomic microarrays is around 20%, so it is possible that the 18p duplication was present at a level undetectable by microarray in the peripheral blood samples. This case suggests that the differences between DNA obtained from saliva and peripheral blood may be, in some cases, more drastic than previously recognized. By testing primarily with DNA from peripheral blood, significant mosaic abnormalities may go undetected. Copyright © 2022

Coronavirus-associated mucormycosis: different from sinonasal mucormycosis.

OBJECTIVE: To study unusual presentations of coronavirus-associated mucormycosis that are rarely seen in sinonasal mucormycosis cases. METHOD: The data of 400 rhino-orbito-cerebral mucormycosis patients admitted to Sawai Man Singh Hospital, Jaipur, from May 2021 to June 2021, were retrospectively collected. The diagnosis of mucormycosis was made by histological examination of biopsy samples. RESULTS: Out of 400 patients, 62 had symptoms other than common symptoms of rhino-orbito-cerebral mucormycosis. Thirty-four patients had facial palsy, 19 complained of gum ulcers, 6 developed a cheek abscess, 2 complained of maggots in the nose along with common rhino-orbito-cerebral mucormycosis symptoms, and 1 had a cerebellar infarct. CONCLUSION: Mucormycosis is a disease with various presentations, and coronavirus-associated mucormycosis has added unusual presentations to the existing list of manifestations of rhino-orbito-cerebral mucormycosis. In this coronavirus disease era, mucormycosis should always be considered as a diagnosis in patients with these unusual presentations.

SEVERE HYPONATREMIA AS A MANIFESTATION OF A NEUROLOGIC DISORDER ASSOCIATED WITH THE COVID-19 VACCINE

SESSION TITLE: Issues After COVID-19 Vaccination Case Posters SESSION TYPE: Case Report Posters PRESENTED ON: 10/19/2022 12:45 pm - 01:45 pm INTRODUCTION: More reports are indicating a temporal association between Bell's palsy and the mRNA vaccine for coronavirus disease 2019 (COVID-19). Therefore, collecting vaccine history is becoming important in post-marketing surveillance to monitor the safety of vaccines in real-world settings. We report the case of concomitant occurrence of Bell's palsy and glossopharyngeal neuralgia leading to severe symptomatic hyponatremia in a previously healthy patient. CASE PRESENTATION: A 60 year-old-female without significant medical history presented to the hospital with odynophagia, and generalized weakness for two weeks. She decreased her oral intake due to stabbing pain in the back of her throat triggered by swallowing. She reported hyperacusis and frequent shooting pain in the left cheek managed with non-steroidal anti-inflammatory drugs. The symptoms occurred several days after the first dose of the mRNA vaccine for COVID-19. She denied previous COVID-19 infection and herpes zoster. Examination revealed dry mucosa, left facial muscle weakness, inability to raise the left eyebrow or lift the labial commissure, effacement of the nasolabial fold, and left-sided frontal wrinkles. Laboratory investigation revealed sodium of 110. Computerized Tomography of the brain revealed negative findings for intracranial abnormalities. Severe symptomatic hyponatremia was managed with hypertonic saline. The neurologist made the diagnosis of Bell's palsy and glossopharyngeal trigeminal neuralgia leading to poor oral intake. We initiated acyclovir, prednisone, and gabapentin. The patient recovered from hyponatremia and experienced improvement of neurological symptoms with initiated medications. DISCUSSION: High morbidity and mortality of patients with COVID-19 accelerated the development and production of the vaccines. During the pandemic, mRNA COVID-19 vaccines reduced asymptomatic and prevented severe symptomatic COVID-19 infection and its complications. Although the benefits and protective effects of the COVID-19 vaccines outweighed the risks associated with them, we have reports of associations between vaccines and certain disorders such as Bell's palsy. Glossopharyngeal neuralgia is defined as sudden severe brief pain in the distribution of the glossopharyngeal nerve. It can be described as transient stabbing pain experienced in the ear, tonsillar fossa, and base of the tongue. Unusual presentation is fear to eat as this can be a precipitating cause of the pain. It overlaps with trigeminal neuralgia and can create a diagnostic dilemma. CONCLUSIONS: In summary, it is unknown what causal relationship exists between the mRNA COVID-19 vaccine and neurological diseases such as Bell's palsy and glossopharyngeal neuralgia. Glossopharyngeal neuralgia is frequently overlooked as a diagnosis. This is a unique case of concomitant glossopharyngeal neuralgia and Bell's palsy that is coincidental with a history of COVID-19 vaccine. Reference #1: El Sahly HM, Baden LR, Essink B, et al.

Impact of COVID-19 pandemic on orthodontic patient’s inflow in daily orthodontic practice: A cross-sectional study

Aim: To evaluate the effects of the COVID-19 pandemic and lockdown on orthodontic patients’ apprehension and inflow and to investigate the treatment-related problems encountered during the pandemic. Materials and Methods: A cross-sectional study was carried out in Saudi Arabia, and patients with active orthodontic treatment were reached via an online questionnaire. A total of 260 orthodontic patients agreed to participate in the study. The sample size calculation was performed using the Raosoft sample size calculator based on the estimation of 75% of the population need orthodontic treatment. The questionnaire included three sections: demographic data, patient fear, and troubles encountered during the lockdown. A link was sent to the participants via different social media platforms and applications. The chi-square goodness-of-fit test was used to assess differences between the variables. Pearson correlation, binomial logistic regression, and multiple logistic regression tests were used to assess the extent of the relationship between patient apprehension and safety measures of COVID-19, as well as between patient orthodontic-related problems. Results: About half of the participants (52.3%) were not afraid of COVID-19 or panicked;however, 54% of them felt depressed during the lockdown. More than 80% were not afraid of visiting the orthodontists or thinking of changing their orthodontists for safety measures and did not want to postpone their treatment. The participants felt that excellent disinfection was the most important measure of infection control followed by wearing masks, face shields, and protective clothing. Conclusion: COVID-19 and the lockdown have a noticeable impact on the patients’ apprehension and dejection. A very high percentage of patients in this study showed no hesitation to visit their orthodontists, and they did not want to stop their treatment during the pandemic. The most common treatment-related problem reported was cheek injury, followed by bracket breakage.

Adjusting the TMIST study design to accommodate slower than expected accrual: ECOG-ACRIN EA1151

Background: The ECOG-ACRIN Tomosynthesis Mammographic Imaging Screening Trial (TMIST), which opened in 2017, is a randomized trial designed to assess whether Tomosynthesis Mammography (TM) should replace Digital Mammography (DM) for breast cancer screening. It is hypothesized that women assigned to TM for 3-5 screening rounds will have fewer advanced breast cancers than the women assigned to DM. Advanced cancers are those that have distant metastases or positive nodes, are invasive tumors greater than or equal to 2.0 cm in size, or are invasive tumors greater than 1.0 cm in size that are triple negative or HER 2+. The initially planned enrollment of 164,946 women was due to be completed by the end of 2020, with follow-up concluded by 2025. There were substantial challenges in meeting this timeline, including the organizational and funding structure of the NCI National Clinical Trials Network which is dependent upon sites using their existing staffing resources (not always readily available at the time of study activation). This led to longer than anticipated start of enrollment for most interested sites and lower than anticipated annual enrollment per participating site based ultimately on the staffing support that could be allocated to manage TMIST. In addition, research staffing shortages and periodic research operations closures due to COVID-19 have also impacted enrolling TMIST sites, though unevenly, since the start of the pandemic. Enrollment plateaued at approximately 2,100 subjects per month by the end of 2020. With that accrual rate expected, the trial design was modified to reduce the sample size so that the study could be completed by 2027. Methods: With the approval of the NCI CIRB, we changed how the primary endpoint measure for TMIST is assessed from the number of advanced cancers that occur by 4.5 years after randomization to the time from randomization to occurrence of advanced cancers. All advanced cancers occurring within 7 years of randomization are now included and all participants followed for at least three years. In addition, the power of the study of the study was modified from 0.9 to 0.85, while the originally assumed effect size at 4.5 years was retained These changes allowed a reduction of sample size to 128,905, with subject recruitment projected to end in 2024. As of February 14, 2022, there are 125 sites open, 114 in the U.S. and 11 in other countries, with an additional 31 sites planning to open. As of February 14, 2022, a total of 63,845 women have been enrolled in the trial worldwide at 115 sites, with 20% of US participants self-identifying as belonging to minority racial and ethnic groups and 70% consenting to optional blood and/or buccal cell collection.

Facial dermatoses due to increased use of masks in medical students during COVID-19 pandemic: A cross sectional study from JSMU

Objective To determine the frequency of skin manifestations associated with prolonged mask wearing during the course of ongoing COVID-19 pandemic. Methods A cross-sectional study was conducted at Jinnah Sindh Medical University (JSMU), Karachi. A total of 138 medical students, who gave history of wearing masks were enrolled. The demographic data including age, gender, and their year of education was collected. A total of 20 questions were asked related to the type of mask, duration of wearing mask, associated and underlying skin disorders, etc. All information was carefully recorded on Google forms. Results This study included 138 participants, 124 (89.9%) females and 14 (10.1%) males. The type of masks used by the medical students varied, however 84.8% used surgical masks. The average duration of mask wear was 4 hours for 72.4% of the participants. There was no significant relation between skin changes and the type and duration of mask wear. The common skin manifestations reported in this study were itching (24.6 %), redness (27.5%), rash (10.1%), burning sensation (12.3%), acne (24.6%), pimples (37.7%), pigmentation (8.7), cracked skin (1.4%), scaling of skin (2.9%), and 29.7% reported no changes. The most frequently affected locations were cheeks (41.3%), followed by chin (13.8%), nasal bridge (10.1%) and perioral area (8%). Participants with history of atopic dermatitis were affected slightly more by itching, redness, rash, burning sensation, acne than those without a history of atopic dermatitis however these manifestations had no significant relation (p>0.05). Pressure bruises were reported in 23.9% of the participants and there was no significant relation with the skin manifestations. About 33% of the females who use makeup under the mask found it inconvenient due to pimples and itching. (p<0.05). Relationship between different skin types and use of cleansers for maintaining skin hygiene generally (p=0.006) and after taking mask off is significant (p=0.034). Significant relation exists between people experiencing pimples after taking off masks and using oral/systemic drugs (p=0.003), and other products (ice cubes, day cream, steroids, skincare regime) for management (p=0.012). Significant relation exists between acne after taking off mask and use of topical drugs (p=0.034). Conclusion The increase in skin manifestations is associated with the increased use of face masks during the COVID 19 pandemic among medical students. As mask wearing can't be compromised due to the nature of the working environment, certain guidelines need to be established to prevent or reduce the occurrence of such manifestations.

Examination The Incidence of Dental, Neurological, Cardiovascular and Radiological Problems in Patients Affected by Covid-19 And Methosd of Drug Therapy in Patients

This study has done a systematic review of drug therapy and assessment of the occurrence of dental and neurological problems in patients affected by covid-19. There are various reasons that can cause an infection in the tooth. One of the most common causes of tooth infection is root canal treatments you have had in the past. Unfortunately, bacteria grow in this area and can lead to infection. Having an infection in the tooth can be very dangerous. Because it may spread to other parts of the body and cause serious problems. For this reason, it is very important to recognize the symptoms of infection. When a crack or cavity is formed on the tooth, if not treated in time, an infection may occur in the tooth. Because these are the gates that can pave the way for bacteria to enter your teeth. The most common type of disease is accompanied by episodes of severe pain that may be felt in the eyes, ears, lips, nose, forehead, cheeks, teeth or jaws, or anywhere on the face. The similarity of the symptoms of this complication with the symptoms of common dental diseases is a factor in misdiagnosis. This can lead to a series of unnecessary dental treatments that not only won't solve the problem, but may actually make it worse. Some patients undergo dental treatment at least once before the diagnosis of the disease. 1.

Shades of COVID-19 vaccine

SARS-CoV-2 infection is associated with a wide spectrum of skin manifestations and few may appear after immunization with vaccines expressing the SARS-CoV-2 spike protein. The COVID-19 pandemic has led to the rapid invention and approval of vaccines and, like any vaccination programme, reports of side-effects have begun to emerge. Though initial reports were about mild side-effects, reports of varied other moderate to severe side-effects have now started to emerge. Although these side-effects seem to be rare, the symptoms can be severe and data on them are scarce. We report a case of a 49-year-old woman with Fitzpatrick skin type VI developing coin-shaped well-defined, round to oval, erythematous to violaceous plaques with central dusky appearance along with vesicles and bullae on her right cheek, left cheek and left posterior thigh. This was seen a few days following each dose of AstraZeneca COVID vaccine but self-resolved in about 2 weeks with hyperpigmentation. There was no cutaneous disease elsewhere and no mucosal involvement. We considered a diagnosis of fixed drug eruption (FDE) based on history and clinical features. FDEs represent a cutaneous adverse drug reaction characterized clinically by the appearance of recurrent, quasiidentical, cutaneous eruptions in the same anatomical location on exposure and re-exposure to the offending drug.

Paediatric inflammatory multisystem syndrome (PIMS-TS): a novel condition

Paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 infection (PIMS-TS) is a novel condition which has recently emerged during the COVID-19 pandemic, consisting of persistent fever, inflammation, and evidence of single- or multiorgan dysfunction, with additional features where any other microbial causes has been excluded (https://www.rcpch.ac.uk/resources/paediatric-multisysteminflammatory- syndrome-temporally-associated-covid-19-pimsguidance). A 16-year-old healthy male presented with a 48-h history of headache, fever, diarrhoea, vomiting and a widespread rash. One month prior he had contracted SARS-CoV-2 with no complications. On examination there was a maculopapular rash across the trunk and buttocks with petechiae present on the lower limbs and flexural folds in addition to an erythematous rash across the nasal dorsum and cheeks. Blood tests revealed lymphopaenia, thrombocytopenia, hypertriglyceridaemia and raised C-reactive protein and ferritin. Autoimmune screen and SARS-CoV-2 polymerase chain reaction tests were negative. A skin biopsy revealed features of a SARS-CoV-2 related urticarial reaction pattern. The patient was treated for myocarditis, fulfilling the diagnosis of PIMS-TS. He was transferred to a specialist intensive care unit and treated with intravenous immunoglobulins and steroids, infliximab, aspirin and topical steroids. He is currently undergoing investigations for encephalitis post admission. PIMS-TS is a rare syndrome that shares features with Kawasaki disease, toxic shock syndrome, macrophage activation syndrome and bacterial sepsis. Haemophagocytic lymphohistiocytosis has also been linked to SARS-CoV-2 (Retamozo S, Brito-Zerón P, Sisó- Almirall A et al. Haemophagocytic syndrome and COVID-19. Clin Rheumatol 2021;40: 1233-44). Clinicians should consider PIMS-TS as a differential in any child presenting with a fever, rash and evidence of systemic inflammation. Early recognition, involvement of a multidisciplinary team and prompt referral to critical care is essential in managing this life-threatening condition.

A study on occupational skin diseases in during Covid-19 in Sardjito general hospital

Background: It was compulsory to wear personal protective equipment (PPE) during Covid-19 pandemics. For health care workers, adverse skin reactions due to PPE usage and hand hygiene protocol were considered as occupational skin dermatoses (OSD). Objectives: To characterize adverse skin reaction due to PPE in health care workers before and during Covid-19 pandemics in tertiary hospital in Yogyakarta, Indonesia. Methods: A hospital-wide survey was conducted and the staffs were asked to answer questions via online form to compare adverse skin reaction before and during pandemic. The survey was a modified NOSQ-2002 with the addition of skin adverse reaction from face shield and googles, hand hygiene protocol, gloves, medical masks, N95 masks, coverall and gown, head cap, boot, and respiratory masks. Results: A total of 151 responses from health care workers were collected. Mean age of respondents was 34.1 years, with the majority being doctors (59.61%). The percentage of occupational dermatoses was increased during the pandemics, 34.44% (before the pandemics) vs 47.68% (during the pandemics). N95 masks had the largest percentage of OSD during pandemics (12.58%). Both before and during the pandemics, the most common location of skin problems was cheek, the percentage were 7.95% and 12.58%, respectively. Furthermore, the number of skin-related complaints were increased during the pandemics. Alcohol-based hand rub also related to adverse skin reaction in hands. Conclusions: A hospital-wide survey was conducted to characterize occupational dermatoses in health care workers during Covid-19 pandemics. Recommendations should be put in place to prevent these adverse skin reactions due to PPE.

Study of patterns of presentation in post COVID19 mucormycosis

Objective: To study the clinico-radiological presentation patterns in patients of post COVID-19 mucormycosis. Background: COVID-19 infection has been responsible for various neurological disorders like stroke, encephalitis, Guillain Barre syndrome etc. almost all over the world. The second wave of this deadly virus was followed by sudden upsurge of cases of mucormycosis in India. While the exact reason for this is still unknown, it is hypothesized to be attributed to steroid use in immunocompromised states like Diabetes Mellitus and possible contamination of intranasal oxygen with industrial oxygen. There have been various patterns of presentations of these patients to mucor units. Neurological involvement was seen in majority of these cases. This study was aimed to study clinical and radiological aspects of such patients. Design/Methods: Total 81 patients, diagnosed as mucormycosis after recovery from COVID-19 illness and who got admitted in mucor units of two tertiary care hospitals of India were included in the study. The presenting clinical features and radiological patterns of involvements were assessed. Results: Out of 81, 46(56.79%) were males and 35(43.21%) were females. Maximum 21(25.92%) patients were between 51-60 years. Most common presenting complaints were heaviness over cheek followed by headache, blurring of vision, nasal discharge, nasal crusting, chemosis of eye, decreased facial sensations and hemiparesis. MRI findings included sinusitis, cavernous sinus thrombosis, orbital cellulitis, anterior circulation infarcts and intracranial fungal abscesses. Rhino-orbital-cerebral mucormycosis was the most common pattern seen in 49(60.49%) patients followed by rhino-orbital form in 19(23.45%) patients and rhino-cerebral mucormycosis in the remaining 13(16.04%) patients. Conclusions: Mucormycosis has emerged as an important complication of COVID-19 infection after the second wave of pandemic in India. Major neurological manifestations have been seen to be associated with it. Lessons need to be learned from this mucormycosis epidemic for prevention of spread and management of this dreaded entity in other regions of the world.

Management of Post COVID Mucormycosis -Maxillectomy

Background:Mucormycosis has been increasingly described in patients with covid 19 2nd wave (delta variant) which is a highly contagious disease caused by SARS-COV-2 is the leading cause of global pandemic. AIM AND OBJECTIVES: To evaluate etiology, indications, management options and complications in patients managed with endoscopic and external maxillectomy after mucormycosis, to evaluate the incidence and distribution of cases who had extensive mucormycosis and to evaluate the outcome of the management options. Materials and Methods: This is a prospective study done in 30 cases at a tertiary care centre.All the patients were subjected to detailed history taking, clinical examination, endoscopic, radiological, pathological, microbiological investigations after taking informed consent. Patients with age group(30yrs -70yrs) who presented with ROM with extensive maxillary sinus involvement and destruction of different walls of the maxillary sinus were managed with different types of maxillectomies. Results: In this study, 30 cases of post covid rhinoorbital mucormycosis who presented to our hospital were studied, among male 24(80%) & females6 (20%).12 patients (40%) were in 5th to 6th decade and 9 patients (30%) in 4th to 5th decade.Main presenting features were unilateral cheek pain, cheek swelling, nasal obstruction, loosening of teeth, tooth ache, cheek numbness, headache, periorbital edema, visual disturbances being present in 95% of the patients.5% presented with epistaxis, ptosis, diplopia alone.90% patients were known case of diabetes milletus,10% are denovo diabetes.All the patients were subjected to routine blood investigations, microbiological, radiologicalinvestigations.(CT, MRI contrast- PNS, Orbit & Brain).Most commonly seen in males 80%. 1 patient had to undergo orbital exenteration,3 patients underwent palatal resection. Conclusion: Debridement of sinuses is necessary in all cases of mucormycosis so that the fungal reservoir could be removed and the antifungal therapy can reach the viable areas. Therefore the management of mucormycosis is individualised to each patient based on the extension of the disease and overall general conditon of the patient.

Arteriovenous Malformation of Upper Lip - a short cure for gross deformity

Aim: To evaluate the safety and success of facial artery ligation alone in arteriovenous malformation of upper lip in non-affording patients. Methodology: This prospective study was conducted at Department of Plastic surgery, on 11 consecutive patients with recurrent upper lip arteriovenous malformation who couldn’t afford angioembolization and frequent hospital visits for staged procedures. We did debulking of lesion after facial artery ligation and cosmetic lip correction. Results: Total 11 patients (9 males and 2 females) were included in this study. Majority of patients showed satisfactory results with facial artery ligation alone. One patient lost the follow up. No significant complication was noted in any patient. No recurrence was noted at 6 months and 1 year follow-up. Patient satisfaction rate remained 8.6±0.96 as per VAC. Conclusion: facial artery ligation alone provides an easy and approachable option for arteriovenous malformation where cost affordability for angioemboization and repeated hospital visits are main limitations.

Early CT and MRI Signs of Invasive Fungal Sinusitis Complicating COVID-19 Infection Managed by Corticosteroids

Objective: Corticosteroids are usually prescribed for severe cases with SARS-CoV-2 (COVID-19). Despite their importance to decrease patients' mortality, they can cause serious side effects like fulminant fungal infection that can damage lungs or invades the sinuses then rapidly spreads to the orbit and even intracranially. Unless early diagnosed and properly managed;patients can lose their vision or die from cavernous sinus thrombosis or other intracranial complications. We are presenting a case that had been scanned with MRI followed by CT for facial drop and cheek swelling issues. The scan demonstrated early subtle signs that raised the suspicion of diagnosis of mucormycosis before the appearance of other clinical signs. This helped in early proper management that did not cost the patient any morbidity and saved his life. Conclusion: Early CT/MRI radiological signs of invasive fungal sinusitis that complicated COVID-19 infection aid in diagnosis and proper timely management of this fatal disease.
