RESUMEN
Phototherapy (PT) is a widely used treatment for neonatal jaundice, yet the ideal model of application remains controversial. In this study, the effects of continuous phototherapy (CPT) and intermittent phototherapy (IPT) models were compared in the treatment of neonatal indirect hyperbilirubinemia (IHB) and whether IPT is a superior modality is investigated. Single-centre parallel randomized controlled open label trial. A computer-based table of random numbers was used to allocate treatments. Newborns ≥ 34 weeks' gestation who received phototherapy in our neonatal intensive care unit (NICU) between July 2022 and April 2023 were included. CPT was applied continuously for 6 h, and IPT was applied as 2 cycles of 1 h on and 2 h off in a 6-h session. Rebound TSB was measured 8 h after phototherapy was stopped in both groups. Phototherapy duration, TSB reduction rate and rebound bilirubin rate were compared between intervention groups. One hundered and four neonates met the inclusion criteria during the study period. CPT and IPT were each used in 52 newborns. Demographic characteristics of the study groups, including sex, mode of delivery, birth weight, admission weight, age at postnatal presentation, diet, discharge weight, and history of PT in siblings, were similar (p > 0.05). The most common cause of IHB in both groups was ABO incompatibility. The median phototherapy time was 12 h (6-15) in the CPT group and 4 h (2-4) in the IPT group (p < 0.001). The mean rate of bilirubin decrease was 1.12 ± 0.73 mg/dl/h in those who underwent IPT and 0.51 ± 0.33 mg/dl/h in those who underwent CPT (p < 0.001). The mean rebound bilirubin rate 8 h after phototherapy was 0.08 ± 0.28 mg/dl/h in the CPT group, and -0.01 ± 0.17 mg/dl/h in the IPT group (p = 0.039). The length of hospital stay was longer in the CPT group (p = 0.032). Skin rash, diarrhoea and increased body temperature were less frequent in the IPT group (p < 0.001). CONCLUSIONS: In this study, IPT was found to be at least as effective as CPT in reducing total serum bilirubin. Even though the duration of PT is shorter in IPT, the slower rate of rebound bilirubin, shorter hospital stays and lower incidence of side effects indicated that intermittent phototherapy is superior to continuous phototherapy. Choosing IPT over CPT is a more rational approach in neonatal jaundice. CLINICALTRIALS: gov Identifier: NCT06386731 (registered retrospectively on 23/04/2024) What is Known: ⢠PT is common used in the treatment of neonatal jaundice. ⢠There is no standard model of application for PT. WHAT IS NEW: ⢠The IPT model is as effective as CPT. ⢠Newborns are discharged faster with IPT.

BACKGROUND: SARS-CoV-2 related multisystem inflammatory syndrome in children (MIS-C) is a newly defined clinical entity in pediatric ages resembles Kawasaki Disease or toxic shock syndrome. Here we aimed to raise awareness about this SARS-CoV-2 related syndrome. METHODS: Children diagnosed with MIS-C and followed in Pediatric Clinic between November 2020 and January 2021, were included in study. Data about patients' demographic characteristics, clinical and laboratory findings, treatment and outcomes were collected from medical records. RESULTS: The median age of 20 children with MIS-C was 80.5 months, 11 of them were male. The most common symptoms at admission were fever (100%), abdominal pain (70%), myalgia (50%), and rash (50%). Lymphopenia, elevated inflammatory markers and cardiac enzymes were their main laboratory findings. Cardiac involvement (90%) consisted of myopericarditis, valvulitis, left ventricular dysfunction, and coronary arteritis. Symptoms mimicking acute appendicitis and ileus were due to gastrointestinal involvement (50%). Macular rash on the trunk, erythema on upper eyelids were striking. Empiric antibiotics and intravenous immunoglobulin were used in all patients, glucocorticoids (90%), anti-thrombotic (65%) and vasoactive (45%) agents were used according to severity of disease. Response to IVIG treatment was poor, whereas glucocorticoids have dramatic affect. Seven patients (35%) were monitored in intensive care unit, none of them required intubation, mechanic ventilation or ECMO. The median recovery time, that is, the period when fever subside and inflammatory markers returned to normal was 9.5 days. CONCLUSIONS: Glucocorticoids has critical role in treatment of MIS-C, early recognition and treatment may decrease need for intensive care by providing rapid recovery.
RESUMEN
Paraoxonase (PON1) protects low and high-density lipoproteins (LDL and HDL) against oxidation induced by reactive oxygen species formation facilitated by iron (Fe) and copper (Cu) ions. Plasma PON1, arylesterase, oxidized LDL (Ox-LDL), Cu, Fe, thiobarbituric acid-reactive substances (TBARS), lipid, lipoprotein, and apolipoprotein profile in bronchial asthma were determined and the relations among these parameters in different steps of asthma were interpreted. A total of 58 individuals, 30 asthmatics and 28 controls, were included into the scope of this study. Plasma PON1, arylesterase, and TBARS levels were measured spectrophotometrically. Determination of plasma oxidized LDL, Cu, and Fe levels were performed by enzyme-linked immunosorbent assay, atomic absorption spectrophotometry, and the automated TPTZ method, respectively. Apo-A-1 and Apo-B levels were determined immunoturbidometrically. Plasma total cholesterol, triglyceride, and HDL cholesterol levels were enzymatically determined. Plasma LDL levels were estimated using the Fridewald formula. The average plasma PON1 and arylesterase activities in the group of patients were lower than those of the individuals in the control group, but there was no statistically significant difference found between them (p > 0.05). No significant difference was found in plasma Apo-A-1, Apo-B, total cholesterol, triglyceride, HDL, and LDL concentrations between the control and patient groups (p > 0.05). Plasma oxidized LDL (p < 0.05), Cu (p < 0.01), Fe (p < 0.01), and TBARS (p < 0.001) levels in patients with asthma were found to be significantly higher than for the control group. Increases in Cu, Fe, lipid peroxidation, and oxidized LDL levels supported by relative decreases in PON1 activities observed in asthmatic patients might be introduced as the striking findings as well as the possible potential indicators of this airway disease, the prevalence of which has increased dramatically over recent decades.

BACKGROUND: Prescription of continuous oxygen therapy (COT) for correct indications, adequate education of the patients, and a regular and sufficient oxygen intake are essential. OBJECTIVE: To evaluate the indications of COT prescriptions in six different centers around Istanbul and patient compliance. METHODS: The initial data of the cases were taken from hospital records and throughout the study personal visits were done as well as arterial blood gas (ABG) analyses. RESULTS: 86 patients out of 110 (78.1%) were found to be eligible candidates for COT. Daily duration of therapy was more than 15 h in 55 (43.3%) and more than 12 h in 14 (11%) of the cases. During therapy, mean PaO(2) values have increased from 52.1 +/- 11 to 58.6 +/- 12 mm Hg (p < 0.001), while mean PaCO(2) values have decreased from 50.16 +/- 9.6 to 48.02 +/- 9 mm Hg (p < 0.05). 98 of the cases (77.1%) stated that they had benefited from the therapy. CONCLUSIONS: We conclude that COT is an effective treatment modality, but patient compliance remains a problem.

Toxic shock syndrome (TSS) is an illness defined by the occurrence of fever, rash, hypotension, multiple organ system dysfunction, and desquamation. Nonmenstrual TSS is often associated with surgical or nonsurgical cutaneous infections, which are rarely purulent or inflamed (Reingold AL, et al. Nonmenstrual toxic shock syndrome: a review of 130 cases. Ann Intern Med 1982; 96:871-4). Toxic shock syndrome associated with peritoneal exit-site infection but without peritonitis is extremely unusual (Sherbotie JR, et al. Toxic shock syndrome with Staphylococcus aureus exit-site infection in a patient on peritoneal dialysis. Am J Kidney Dis 1990; 15:80-3). We describe 2 patients that met the Centers for Disease Control case definition of TSS secondary to a peritoneal dialysis catheter exit-site infection with signs of mild inflammation and growth of Staphylococcus aureus, but with no evidence of peritonitis.
