RESUMEN
BACKGROUND: Data on the risk factors and outcomes for pediatric patients with SARS-CoV-2 infection (COVID-19) following hematopoietic stem cell transplantation (HSCT) are limited. OBJECTIVES: The study aimed to analyze the clinical signs, risk factors, and outcomes for ICU admission and mortality in a large pediatric cohort who underwent allogeneic HSCT prior to COVID-19 infection. METHOD: In this nationwide study, we retrospectively reviewed the data of 184 pediatric HSCT recipients who had COVID-19 between March 2020 and August 2022. RESULTS: The median time from HSCT to COVID-19 infection was 209.0 days (IQR, 111.7-340.8; range, 0-3845 days). The most common clinical manifestation was fever (58.7%). While most patients (78.8%) had asymptomatic/mild disease, the disease severity was moderate in 9.2% and severe and critical in 4.4% and 7.6%, respectively. The overall mortality was 10.9% (n: 20). Deaths were attributable to COVID-19 in nine (4.9%) patients. Multivariate analysis revealed that lower respiratory tract disease (LRTD) (OR, 23.20, p: .001) and lymphopenia at diagnosis (OR, 5.21, p: .006) were risk factors for ICU admission and that HSCT from a mismatched donor (OR, 54.04, p: .028), multisystem inflammatory syndrome in children (MIS-C) (OR, 31.07, p: .003), and LRTD (OR, 10.11, p: .035) were associated with a higher risk for COVID-19-related mortality. CONCLUSION: While COVID-19 is mostly asymptomatic or mild in pediatric transplant recipients, it can cause ICU admission in those with LRTD or lymphopenia at diagnosis and may be more fatal in those who are transplanted from a mismatched donor and those who develop MIS-C or LRTD.

OBJECTIVE: In this study, we aimed to describe the relationship between the localization of rarely seen upper extremity war injuries and their complications in the subacute period, and define our preferences for surgery and antibiotic use. METHODS: Patients with an upper extremity war injury who presented to our institution between 2015 and 2018 were retrospectively evaluated. Data regarding demographics, time between injury and presentation, location of injury, type of damage, complications, treatment methods, infection rates and antibiotic use were recorded. Tissue defects, fracture fixation, neurovascular damage, infection development and treatment approaches were analyzed. RESULTS: Sixty-two male patients with isolated upper extremity injuries (mean age: 31.66 ± 8.28 years) were included in the study. The average time between trauma and hospitalization was 14 days. The mean hematocrit (Hct) level at presentation was 36.3 ± 6.8%. Patients had been followed up for an average period of 95.6 ± 32.1 days. Twenty-nine patients (46.8%) had nerve injury, eight (12.9%) had arterial injury that required repair, and 23 had infection (37.1%), of which five developed osteomyelitis. Infection was polymicrobial in nine cases and monobacterial in 14. A positive correlation was found between the presence of fracture and nerve injury (p = 0.013). The frequency of nerve injuries due to gunshot wounds was higher in the mid-section and lower part of the arms and in the proximal forearm when compared to other regions (p = 0.011). The infection rates were significantly higher in patients with fractures (p = 0.033). The mean hematocrit (Hct) level at presentation of the patients with infection (32.1 ± 6.3%) was significantly lower than that of those who did not have infection (38.8 ± 5.9%) (p<0.001). CONCLUSION: Upper extremity war injuries require case-specific solutions. Microbiological samples should be taken prior to empirical antibiotic treatment for infection management and rational antibiotic use principles should be applied according to the culture and antibiogram results. The holistic and ambiguous character of nerve injuries often requires early exploration and combined reconstructive interventions. Arterial injuries can be overlooked by physical examination alone and thus routine angiography should be performed. Completion of the bone and soft tissue reconstructions in the same session using a holistic approach minimizes the possible risks.

Coronavirus disease 2019 (COVID-19) is a recently recognised pandemic spreading rapidly from Wuhan, Hubei, to other provinces in China and to many countries around the world. The number of COVID-19-related deaths is steadily increasing. Acute ST-segment elevation myocardial infarction (STEMI) is a disease with high morbidity and mortality rates, and primary percutaneous coronary intervention is usually recommended for the treatment. A patient with diabetes mellitus and hypertension for five years was admitted to the emergency unit with symptoms of fever, cough and dyspnoea. These symptoms were consistent with viral pneumonia and a COVID PCR test was performed, which tested positive three days later. The patient had chest pain on the eighth day of hospitalisation. On electrocardiography, simultaneous acute inferior and anterior STEMI were identified. High levels of stress and increased metabolic demand in these patients may lead to concomitant thrombosis of different coronary arteries, presenting with two different STEMIs.

RESUMEN
UNLABELLED: Hepatitis C virus (HCV) infection becomes chronic in about 85 % of individuals as demonstrated by the persistence of HCV. It is necessary to treat acute hepatitis C infection. Interferon-alpha is generally used for the treatment of acute HCV infection. CASE PRESENTATION: A 55-year-old woman with a history of fatigue and icter was diagnosed as acute hepatitis C virus infection. She was treated with interferon-alpha 2b 3 million unite sc three times in a week and ribavirin 1000 mg daily for 6 months. Within 2 weeks of therapy, the alanine aminotransferase (ALT) had became normal. At the end of the 3 months of therapy, HCV RNA was negative and remained negative 6 months after the end of interferon treatment (sustained response). CONCLUSION: This report suggests that interferon-alpha 2b and ribavirin may have a role in treatment of acute hepatitis C virus infection.
