Relationship of regional ultraviolet index data with rash and systemic disease activity in youth with childhood-onset systemic lupus: results from the Childhood Arthritis and Rheumatology Research Alliance Registry.

OBJECTIVE: To investigate the association between ultraviolet light index (UVI), as a marker for UV exposure, and seasonality with rash and systemic disease activity in youth with childhood-onset systemic lupus (cSLE) from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry. METHODS: We reviewed data on rash and disease activity from Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2 K) scores from cSLE CARRA Registry participants with visits between 2010 and 2019 and obtained zipcode level UVI data from the National Oceanic and Atmospheric Administration (NOAA). Our main exposures were UVI and season during the month of visit and one month prior to visit. We used mixed-effects logistic regression models to examine associations between regional UVI (by zipcode)/season and odds of rash and severe SLEDAI-2 K score (≥ 5 vs. 0-4), adjusting for age, sex, race and income. RESULTS: Among 1222 participants, with a mean of 2.3 visits per participant, 437 visits (15%) had rash and 860 (30%) had SLEDAI-2 K score ≥ 5. There were no associations between UVI during the month prior to visit or the month of the visit and odds of rash or elevated systemic activity. However, fall season was associated with increased odds of rash (OR = 1.59, p = 0.04), but not increased disease activity. CONCLUSION: This study found no association between UVI and rash or UVI and disease activity. However, further studies directly measuring UV exposure and accounting for patient-level protective behavioral measures may help to better understand the complex relationship between sun exposure and SLE disease activity.

[Cutaneous Lyme disease: not always a rash with a central clearing]. / Cutane lymeziekte: lang niet altijd een rode ring.

During the past four decades the number of reported Lyme disease diagnoses in the Netherlands has increased to 27.000 a year, with a yearly incidence of Lyme disease between 111 (95% CI 106-115) to 131 (95% CI 126-136) per 100,000 person years. A large part of all Lyme disease diagnoses concern the skin; in the Netherlands, 77-89% erythema migrans, 2-3% borrelia lymfocytoom and 1-3% acrodermatitis chronica atrophicans. These skin manifestations have a variable clinical expression, reason why they can be difficult to diagnose. Early recognition and treatment is important to prevent the development of systemic manifestations.

Fever and Rash.

Infectious causes of fever and rash pose a diagnostic challenge for the emergency provider. It is often difficult to discern rashes associated with rapidly progressive and life-threatening infections from benign exanthems, which comprise the majority of rashes seen in the emergency department. Physicians must also consider serious noninfectious causes of fever and rash. A correct diagnosis depends on an exhaustive history and head-to-toe skin examination as most emergent causes of fever and rash remain clinical diagnoses. A provisional diagnosis and immediate treatment with antimicrobials and supportive care are usually required prior to the return of confirmatory laboratory testing.

Red in the face: Approach to diagnosis of red rashes on the face.

BACKGROUND: A red rash on the face in an adult patient is a common presentation to general practice in Australia. Rashes on the face significantly affect quality of life because this is a cosmetically sensitive site. Ascertaining the correct diagnosis is therefore of utmost importance so that appropriate treatment can be initiated. OBJECTIVE: This article discusses the assessment of red rashes on the face in an adult patient. DISCUSSION: Diagnosing a red rash on the face requires assessment of symptomology, age of onset, rash morphology and 'clinical clues' that help delineate between differentials. Although the list of differential diagnoses is wide, many of the common diagnoses can be made clinically without the need for investigations. Investigations such as skin biopsy are useful if the diagnosis is unclear, if the rash is not responding to initial treatment and/or a referral to a dermatologist is being considered.

A woman in her fifties with a post-operative infection, generalised rash and organ failure. / En kvinne i 50-årene med postoperativ infeksjon, generalisert utslett og organsvikt.

Background: Toxic shock syndrome (TSS) is a rare but potentially life-threatening disease caused by superantigen-producing Gram-positive bacteria such as Staphylococcus aureus and Streptococcus pyogenes. Staphylococcal TSS received special attention from 1978 to 1981, when an epidemic was observed associated with the use of hyper-absorbent tampons. Today the disease is rare and generally not related to menstruation, but can occur postpartum or in post-surgical wounds, intrauterine devices (IUDs), burns or other soft tissue injuries, mastitis or other focal infections. The annual incidence of staphylococcal TSS is around 0.5/100 000 and around 0.4/100 000 for streptococcal TSS. The mortality in menstrual-related cases is < 5 % and up to 22 % in non-menstrual related cases. Case presentation: This article presents a case of a middle-aged woman who developed symptoms of toxic shock syndrome five days after elective breast cancer surgery, with high fever, multiorgan failure and a characteristic desquamation of the palms. Interpretation: Toxic shock syndrome is a potentially lethal, toxin-mediated disease. Symptoms develop quickly, within hours. Early recognition and appropriate surgical management, intensive care and antibiotics are therefore important to reduce mortality and sequelae.

Newborn Skin: Part I. Common Rashes and Skin Changes.

Rashes in the newborn period are common and most are benign. Infections should be suspected in newborns with pustules or vesicles, especially in those who are not well-appearing or have risk factors for congenital infection. Congenital cytomegalovirus infection can cause sensorineural hearing loss and neurodevelopmental delay. Skin manifestations of cytomegalovirus may include petechiae due to thrombocytopenia. The most common skin manifestations of early congenital syphilis are small, copper-red, maculopapular lesions located primarily on the hands and feet that peel and crust over three weeks. Erythema toxicum neonatorum and neonatal pustular melanosis are transient pustular rashes with characteristic appearance and distribution. Neonatal acne is self-limited, whereas infantile acne may benefit from treatment. Milia can be differentiated from neonatal acne by their presence at birth. Cutis marmorata and harlequin color change are transient vascular phenomena resulting from inappropriate or exaggerated dilation of capillaries and venules in response to stimuli.

Reporte de caso de dengue clásico a predominio de sintomatología dermatológica en el marco de la epidemia en la provincia de Misiones 2023-2024 / Case of classic dengue with predominance of dermatologic symptoms in the 2023-2024 epidemic in the province of Misiones

Se presenta un caso femenino de dengue clásico (DC) en el marco de la epidemia 2023-2024 en la provincia de Misiones, con predominio de síntomas dermatológicos de exantemas máculo papulosos, habonosos y eritrodérmicos sobre los síntomas sindrómicos cardinales. Las lesiones presentan componente humoral y de extravasación, sin diátesis ni componentes purpúricos apreciables, presentando una rápida y efectiva evolución al eritema y la normalización con tratamiento antihistamínico y corticoide parenteral. De la misma manera se evalúan alteraciones analíticas hematológicas y hepáticas de gran magnitud, con escasa repercusión clínica, que se mensuran en función del riesgo relativo al dengue hemorrágico (DH) y el pronóstico de la paciente.

Postprandial facial rash in an infant.

ABSTRACT: This article describes an infant who developed a facial rash within minutes of eating certain foods. The rash resolved within 30 minutes. The patient was diagnosed with auriculotemporal syndrome or Frey syndrome, which is characterized by sweating or flushing in the preauricular area when the patient consumes certain foods, especially those that are acidic, sour, or spicy. Because most patients outgrow the syndrome, no treatment is needed.

DRESS syndrome: More than just a rash.

ABSTRACT: Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is rare but carries significant mortality and morbidity, making early identification and definitive management crucial. The diagnosis of DRESS is made clinically and involves consideration of a broad list of differential diagnoses. Given variable clinical presentations among patients with DRESS syndrome, clinicians should look for common findings and other hallmarks of the syndrome while monitoring for known complications. Additionally, clinicians should maintain a high index of suspicion to avoid missing more mild presentations, such as in this case patient with DRESS syndrome minor.
