Urticarial eruption in COVID-19-positive children: A report of two cases

Recent literature has reported a variety of dermatological manifestations in children and adults associated with COVID-19. Herein, we report urticarial eruptions in two COVID-19-positive children. In the first case, urticaria with angioedema preceded a febrile episode and only partially responded to conventional doses of antihistamines. In the second case, urticaria followed the appearance of fever and upper respiratory symptoms. Both cases recovered completely within two weeks of diagnosis. These cases demonstrate that urticaria and angioedema, precedent or following a febrile illness, with or without respiratory symptoms, may be a presenting symptom of COVID-19 infection in children. A high index of suspicion in such cases helps the early administration of treatment and isolation of the patients to limit the spread of the virus.

A clinical prediction tool to predict urinary tract infection in pediatric febrile patients younger than 2 years old: a retrospective analysis of a fever registry

Objective Urinary tract infection (UTI) is a significant issue in young febrile patients due to potential long-term complications. Early detection of UTI is crucial in pediatric emergency departments (PEDs). We developed a tool to predict UTIs in children.Methods Clinical data of patients <24 months of age with a fever and UTI or viral infection were extracted from the fever registry collected in two PEDs. Stepwise multivariate logistic regression was performed to establish predictors of identified eligible clinical variables for the derivation of the prediction model.Results A total of 1,351 patients were included in the analysis, 643 patients from A hospital (derivation set) and 708 patients from B hospital (validation set). In the derivation set, there were more girls and a lower incidence of a past history of UTI, older age, less fever without source, and more family members with upper respiratory symptoms in the viral infection group. The stepwise regression analysis identified sex (uncircumcised male), age (≤12 months), a past history of UTI, and family members with upper respiratory symptoms as significant variables.Conclusion Young febrile patients in the PED were more likely to have UTIs if they were uncircumcised boys, were younger than 12 months of age, had a past history of UTIs, or did not have families with respiratory infections. This clinical prediction model may help determine whether to perform urinalysis in the PED.

The Occupational Health Effects of Responding to a Natural Gas Pipeline Explosion Among Emergency First Responders – Lincoln County, Kentucky, 2019

Objective: The aim of the study was to assess occupational health effects 1 month after responding to a natural gas pipeline explosion. Methods: First responders to a pipeline explosion in Kentucky were interviewed about pre- and post-response health symptoms, post-response health care, and physical exertion and personal protective equipment (PPE) use during the response. Logistic regression was used to examine associations between several risk factors and development of post-response symptoms. Results: Among 173 first responders involved, 105 (firefighters [58%], emergency medical services [19%], law enforcement [10%], and others [12%]) were interviewed. Half (53%) reported at least 1 new or worsening symptom, including upper respiratory symptoms (39%), headache (18%), eye irritation (17%), and lower respiratory symptoms (16%). The majority (79%) of symptomatic responders did not seek post-response care. Compared with light-exertion responders, hard-exertion responders (48%) had significantly greater odds of upper respiratory symptoms (aOR: 2.99, 95% CI: 1.25–7.50). Forty-four percent of responders and 77% of non-firefighter responders reported not using any PPE. Conclusions: Upper respiratory symptoms were common among first responders of a natural gas pipeline explosion and associated with hard-exertion activity. Emergency managers should ensure responders are trained in, equipped with, and properly use PPE during these incidents and encourage responders to seek post-response health care when needed.

Health Risks and Benefits Among Surfers After Exposure to Seawater in Monterey Bay, Santa Cruz County, California, United States

We investigated the health risks and benefits among surfers in Monterey Bay, Santa Cruz County, California, United States after seawater exposure. A total of 47 surfers enrolled and completed an online survey on the effect of the ocean environment on their well-being, physical and mental health, and provided their perspectives on ocean conservation. The majority of the surfers were white males, with a median age of 40 years, and a mean of 21 years surfing experience. Most of the participants spent over 5 h/week in the ocean. The most common health problems reported were adverse effects due to red tide exposure, surfer’s ear, back and neck problems, and allergies. A total of 41% reported upper respiratory symptoms, and 8% of the participants reported gastrointestinal symptoms. All participants reported that the ocean benefited their emotional health, and 45/47 (&gt;96%) reported that the ocean increased their life satisfaction, happiness, and decreased their stress level. All participants reported being engaged in ocean stewardship. This study suggests surfers were significantly more likely to report upper respiratory symptoms when they had experienced adverse health effects while surfing during a “red tide” and during a bloom of the microscopic, single-celled phytoplankter, Akashiwo sanguinea.

Infant Dengue a 10-Year Experience from a Tertiary Center in South India

Dengue remains a major problem in the tropics. Several Asian countries have reported an increasing trend in the proportion of infants with dengue fever. However, most studies are limited to case reports or small case series from isolated outbreaks. We planned this study to look at clinico-laboratory profile, outcome, and predictors of severity in a large cohort of infants over a decade. Electronic medical records of infants admitted at a tertiary center of South India, with laboratory confirmed dengue infection between 2009 and 2019 were reviewed. Diagnosis was based on detection of NS-1 antigen and/or immunoglobulin M antibody against DENV(dengue virus) or positive DENV RNA polymerase chain reaction in infants presenting with acute febrile illness and clinical features consistent with dengue. Of 395 children with dengue admitted during study period, 99 (25%) were infants. A cyclical incidence pattern was noted, with higher cases in alternate years. Fever (99%) was most common, followed by gastrointestinal symptoms (vomiting, diarrhea—28%) and upper respiratory symptoms (cough, coryza—22%). Fifty-three infants had severe dengue, and 39 had shock. Fourteen children had multiorgan dysfunction syndrome, and 13 died. Infants with severe dengue were older than those with nonsevere disease, had lower serum albumin and greater frequency of severe thrombocytopenia, and had coagulopathy. On multivariable analysis, low serum albumin predicted development of severe dengue [P = 0.003, odds ratio 12.4 (95% confidence interval: 2.42–63.7)]. Dengue in infants may be challenging to recognize because of its undifferentiated presentation, with gastrointestinal and upper respiratory symptoms that are similar to other viral illness. Severe dengue is common in this sample, and lower serum albumin at presentation was predictive of severe disease.

Chest CT features of COVID-19 pediatric patients presented with upper respiratory symptoms

Background An outbreak of coronavirus disease 2019 (COVID-19) infection caused by a novel coronavirus began in December 2019 in Wuhan in central China that affect the children and adult and causes respiratory disease. This study aimed to highlight the CT features of pediatric patients with COVID-19 with upper respiratory symptoms. Results The mean age of the 53 patients who enrolled in this study were 14.06 ± 4.12 years (range 1-18 years). Majority (75.5%) of them were adolescent. Running nose and fever were the most common symptoms. Forty-four (83%) patients had normal CT with no ground glass opacity (GGO) or consolidation, only 9 patients showed lung opacities; 5 cases showed consolidation, 2 cases with GGO, while consolidation with GGO was noted in another 2 patients. Among these 9 patient, six (66.7%) of them show unilateral lung opacities with peripheral distribution of these opacities in eight (88.9%) patients. The most frequently affected lobes were right and left lower lung lobes that were noted in 6 out of 9 patients with lung opacities (66.7%) in each lobe. Bronchitis was predominant in 23 (43.4%) cases. Conclusions RT-PCR is a gold slandered test in the diagnosis of COVID-19 in children with upper respiratory tract symptoms as Chest CT cannot standalone as a diagnostic tool owing to high prevalence of normal chest CT in these patients. However, in case of lung affection, the presence of unilateral, peripheral consolidation with lower lobe predominance, in addition to bronchial wall thickening should be considered as a hallmark of chest CT in diagnosis of pediatric patients with COVID-19 with upper respiratory symptoms.

Mother and son cases of Bickerstaff’s brainstem encephalitis and fisher syndrome with serum anti-GQ1b IgG antibodies: a case report

Background Bickerstaff’s brainstem encephalitis (BBE) and Fisher syndrome (FS) are immune-mediated diseases associated with anti-ganglioside antibodies, specifically the anti-GQ1b IgG antibody. These two diseases potentially lie on a continuous spectrum with Guillain-Barré Syndrome (GBS). There are some reports of family cases of GBS and fewer of FS. However, there are no reports of family cases of BBE and FS. Case presentation We report a familial case of an 18-year-old son who had BBE and his 52-year-old mother diagnosed with FS within 10 days. The son showed impaired consciousness 1 week after presenting with upper respiratory symptoms and was brought to our hospital by his mother. He showed decreased tendon reflexes, limb ataxia, albuminocytologic dissociation in his spinal fluid, and positive serum anti-GQ1b antibodies. Haemophilus influenzae was cultured from his sputum. He was diagnosed with BBE and treated with intravenous immunoglobulin (IVIg) therapy, which led to an improvement in symptoms. The mother presented with upper respiratory symptoms 3 days after her son was hospitalized. Seven days later, she was admitted to the hospital with diplopia due to limited abduction of the left eye. She showed mild ataxia and decreased tendon reflexes. Her blood was positive for anti-GQ1b antibodies. She was diagnosed with FS and treated with IVIg, which also led to symptomatic improvement. Conclusions There are no previous reports of familial cases of BBE and FS; therefore, this valuable case may contribute to the elucidation of the relationship between genetic predisposition and the pathogenesis of BBE and FS.

Aphasia and confusion – influenza encephalopathy: atypical presentation of influenza

Influenza encephalopathy, a rare manifestation of influenza infection in the adult population which is not widely recognised, can present with confusion and focal neurological symptoms, including aphasia. The aim of this report is to illustrate the unique presentation of influenza encephalopathy and discuss the need for close attention to and monitoring of this rare but highly fatal disease.A 28-year-old woman was admitted with acute-onset confusion and incoherent speech. CT of the head was unremarkable. Cerebrospinal fluid analysis showed elevation of protein, but was otherwise unremarkable. A detailed history revealed recent upper respiratory symptoms which prompted a rapid influenza test which was positive and oseltamivir was started. The patient’s confusion and aphasia gradually improved and her speech was back to her baseline by the next day.
