Successful Management of Rhino-Orbital-Cerebral Mucormycosis in a Child with Acute-on-Chronic Kidney Disease and Malnutrition: Case report and literature review.

Mucormycosis is a very rare fungal infection in children. It is caused by opportunistic fungi and mainly affects immunocompromised patients. Early diagnosis is very important for a good outcome. Successful management requires the reversal of the underlying predisposing risk factors, surgical debridement and prompt administration of active antifungal agents, with liposomal amphotericin B being the first-line therapy. This case, to the best of the authors' knowledge, is the first rhino-orbital-cerebral mucormycosis to be reported on among Omani children. We highlight the importance of early diagnosis and prompt surgical and medical interventions in achieving a satisfactory outcome and review the published literature in regard to the management.

SARS-CoV-2-related Multisystem Inflammatory Syndrome in Children: A case series.

On 27 April 2020, the National Health Service England issued an emergency alert for a new condition owing to the observation of an increasing number of cases of a COVID-19-related hyperinflammatory syndrome termed multisystem inflammatory syndrome in children (MIS-C). Some of the presenting symptoms appeared similar to the Kawasaki disease and toxic shock syndrome. We report the cases of six children fitting the criteria of MIS-C, admitted to Royal Hospital and Sohar Hospital, Oman, between the months of June and July in 2020. Four of these patients required admission at the paediatric intensive care unit for inotropic support while two were admitted to the paediatric ward on suspicion of appendicitis. MIS-C has been reported in a small number of individuals below the age of 21 years with a median age of 9-10 years. Five of the current patients were aged less than the median age reported in the existing literature. All of the patients showed complete recovery with supportive management, intravenous immunoglobulin and steroids, with one patient requiring interleukin-6 inhibitor (tocilizumab).

Epidemiology, characteristics and outcome of children hospitalized with COVID-19 in Oman: A multicenter cohort study.

OBJECTIVES: To describe the epidemiology, clinical and laboratory features, and outcome of children hospitalized with coronavirus disease 2019 (COVID-19) in the Middle East. METHODS: A multicenter retrospective study of children hospitalized with COVID-19 in 7 centers across Oman between February and July 2020. RESULTS: In total, 56 children <14 years old required hospitalization in 7 Omani centers over 5 months (February - July 2020). Thirty-seven (68%) children were admitted with uncomplicated COVID-19, 13 (23%) with pneumonia and 5 (9%) with multisystem inflammatory syndrome in children. Infants constituted 41% of cases (23/56), approximately half of whom (12/23, 52%) were <2-months old. Fever was the most common symptom (46, 82%), followed by respiratory symptoms (33, 59%), and gastrointestinal symptoms (31, 55%). Twenty-two (39%) children had underlying medical conditions: sickle cell disease (7, 13%), chronic respiratory disease (4, 7%) and severe neurological impairment (4, 7%). Leukocytosis, elevated inflammatory markers and anemia were independently associated with intensive care admission. There were no mortalities related to admission with COVID-19 in this cohort. CONCLUSION: Most of the children hospitalized with COVID-19 had a mild course and a satisfactory outcome. Sickle cell disease is the most common comorbidity associated with pediatric admission of COVID-19 in Oman.

Impact of Infectious Diseases Consultation on Management and Outcome of Staphylococcus aureus Bacteremia in Children.

BACKGROUND: To examine the impact of infectious diseases consultation (IDC) on the management and outcome of Staphylococcus aureus bacteremia (SAB) in children. METHODS: A retrospective cohort study of children with SAB at a teritary pediatric hospital (January 2009-June 2015) identified by medical record review as to whether they received an IDC for SAB at the discretion of the admitting physician or surgeon was conducted. Differences in management and outcomes for those with and without IDC were evaluated, and multivariate regression analysis was used to determine factors associated with cure. RESULTS: There were 100 patients included in the analysis. Fifty-five patients received IDC and 45 had no IDC (NIDC). Appropriate directed therapy within 24 hours (54/55 = 98.2% vs 34/45 = 75.6%, P < .01), choice (54/55 = 98.2% vs 37/45 = 82.2%, P < .01), dose (54/55 = 98.2% vs 36/45 = 80%, P < .01), and duration (52/55 = 94.5% vs 24/45 = 53.3%, P < .01) of directed antibiotic therapy were appropriate in more IDC group patients. Achievement of source control in indicated cases was also more common in the IDC group (28/32 = 87.5% vs 5/26 = 19.1%, P < .01). Appropriate investigation with repeat blood cultures and echocardiograms was not significantly different. All 55 patients in the IDC group had a complete response (cure) compared with 40 of the 45 (88.9%) patients in the NIDC group: 2 patients died and 3 patients had a relapse of infection with subsequent cure. In multivariate regression analysis, methicillin-susceptible SAB and IDC were factors independently associated with cure. CONCLUSIONS: Children who received IDC for SAB in a tertiary pediatric setting were more likely to have appropriate investigations and management and had improved outcomes.

Ongoing Challenges with Healthcare-Associated Candida auris Outbreaks in Oman.

Candida auris has emerged in the past decade as a multi-drug resistant public health threat causing health care outbreaks. Here we report epidemiological, clinical, and microbiological investigations of a C. auris outbreak in a regional Omani hospital between April 2018 and April 2019. The outbreak started in the intensive care areas (intensive care unit (ICU), coronary care unit (CCU), and high dependency unit) but cases were subsequently diagnosed in other medical and surgical units. In addition to the patients' clinical and screening samples, environmental swabs from high touch areas and from the hands of 35 staff were collected. All the positive samples from patients and environmental screening were confirmed using MALDI-TOF, and additional ITS-rDNA sequencing was done for ten clinical and two environmental isolates. There were 32 patients positive for C. auris of which 14 (43.8%) had urinary tract infection, 11 (34.4%) had candidemia, and 7 (21.8%) had asymptomatic skin colonization. The median age was 64 years (14-88) with 17 (53.1%) male and 15 (46.9%) female patients. Prior to diagnosis, 21 (65.6%) had been admitted to the intensive care unit, and 11 (34.4%) had been nursed in medical or surgical wards. The crude mortality rate in our patient's cohort was 53.1. Two swabs collected from a ventilator in two different beds in the ICU were positive for C. auris. None of the health care worker samples were positive. Molecular typing showed that clinical and environmental isolates were genetically similar and all belonged to the South Asian C. auris clade I. Most isolates had non-susceptible fluconazole (100%) and amphotericin B (33%) minimal inhibitory concentrations (MICs), but had low echinocandin and voriconazole MICs. Despite multimodal infection prevention and control measures, new cases continued to appear, challenging all the containment efforts.

Severe thrombocytopenia in a child with typhoid fever: a case report.

BACKGROUND: Although thrombocytopenia is common in typhoid fever, its course, response to treatment, and need for specific therapies such as platelet transfusion are not well characterized. CASE PRESENTATION: We report a case of typhoid fever in a 4-year-old Asian male returned traveler, admitted with prolonged fever and found to have severe thrombocytopenia (platelets 16 × 109/L). Despite appropriate antibiotic therapy, his platelet recovery was slow, but did not lead to complications and he did not require platelet transfusion. CONCLUSIONS: There is no consensus in the medical literature guiding the optimal management of severe thrombocytopenia in typhoid fever, but it may improve with conservative management, as in our case. The epidemiology and management of this condition merits further research to guide clinical practice.
