New parameters on prediction of severity of transient tachypnea of the newborn.

BACKGROUND: Transient tachypnea of the newborn (TTN) is a common clinical problem that often occurs in the first hours of life. Although it is considered to be a benign clinical course, some cases may have severe symptoms and require ventilation support. In this study, we aimed to determine the association between the mean platelet volume (MPV), nucleated red blood cells (NRBCs), right ventricular systolic pressure (RVSP), and the severity of TTN. METHODS: Patients with TTN were divided into two groups according to Silverman score (<7: group 1 [n: 34] and ≥7: Group 2 [n: 30]). The groups were compared in terms of demographic characteristics, hematologic parameters, and RVSP within the first 24 hours after admission. RESULTS: Mean birth weight of the patients was 3033.4 ± 364.1 g and median gestational age was 38 weeks (min-max: 34-42). Patients in Group 2 were found to require higher nasal continuous positive airway pressure (nCPAP) support and longer duration of oxygen treatment (p: 0.001). Patients in Group 2 had significantly higher thrombocyte, absolute NRBCs count, NRBCs/100 WBCs, and RVSP levels (p < 0.05). Hemoglobin and hematocrit levels were found significantly higher in group 1(p < 0.05). In logistic regression analysis, NRBCs/100 WBCs was found to be the most important independent parameter that affects Silverman score at admission (OR: 7.065, CI: 1.258-39.670, p: 0.026). DISCUSSION: This is the first study that investigates the association between NRBCs, RVSP, and severity of TTN. We think that elevated NRBCs and RVSP values are helpful for clinicians in decision making for referral of the patients to a secondary or a tertiary level of NICU and also inform the families about prognosis.

Rhabdomyolysis after BNT162b2 mRNA Covid-19 vaccine in an adolescent male.

Pfizer-BioNTech COVID-19 (BNT162b2) conferred a high level of protection against Covid-19 with a proven short-term safety profile. Although cases of vaccine-associated myopericarditis have been reported, the existence of rhabdomyolysis without myocarditis has not yet been published. A 16-year-old, healthy male patient, who did not use any herbal or illegal drugs before, was admitted with muscle pain that developed after the second dose of BNT162b2 vaccine. Cardiac examination and heart enzymes were normal and the patient had significantly higher creatinine kinase levels. The patient, whose enzymes returned to normal with only force hydration therapy, recovered without complications. Reporting the side effects of the vaccine, which has a short history of application to large populations, is of vital importance in the conduct of vaccine development studies and in identifying the risky group in terms of side effects.

Midodrine treatment in children with recurrent vasovagal syncope.

BACKGROUND: Vasovagal syncope is the most common cause of syncope in childhood and its treatment is not at a satisfactory level yet. We aimed to investigate patients who were diagnosed with vasovagal syncope, did not benefit from conventional treatment, received midodrine treatment, and to evaluate their response to midodrine treatment. METHODS: Files of 24 patients who were diagnosed with recurrent vasovagal syncope, did not benefit from non-pharmacological treatments, and received midodrine treatment during June 2017-October 2019 were retrospectively analysed. RESULTS: In total, 24 patients received a treatment dose of midodrine at 5 mg/day (2.5 mg BID) included in the study. The mean number of syncope was 5.75 ± 2.67 prior to treatment. Following treatment, the mean number of syncope was 0.42 ± 0.89. It was observed that syncope episodes did not recur in 17 patients, but it recurred in 4 out of 7 patients in the first 3 months of the treatment and did not recur in the following months. The episodes improved in two patients with an increase in the treatment dose, but the syncope episodes continued in only one patient. CONCLUSION: It was concluded that midodrine treatment was effective and safe in adolescents with recurrent vasovagal syncope.

A preliminary study of the child abuse and central sensitization in adolescent patients with chronic non-organic chest pain and an overlooked condition: juvenile fibromyalgia syndrome.

BACKGROUND: Only a small percentage of pediatric chest pain is of cardiac origin and the most common detected cause is musculoskeletal. Among musculoskeletal causes, acute chest pain is better described, with the causes of chronic pain not being adequately investigated in the literature. The aim of studuy is to evaluate the musculoskeletal causes of non-cardiac chest pain and investigate the relationship of chest pain with child abuse and central sensitization. METHODS: Patients aged 12 to 18 years presenting with chest pain for at least 3 months were evaluated by a pediatric cardiologist and those without an organic pathology were referred to the physical medicine and rehabilitation clinic. In addition to detailed history and physical examination, juvenile fibromyalgia was questioned according to the 2016 revised diagnostic criteria of the American College of Rheumatology. The visual analog scale (to measure intensity of chest pain), the Central Sensitization Inventory (to evaluate the presence of central sensitization), the Hospital Anxiety Depression Scale (to determine depression and anxiety), the Childhood Trauma Questionnaire (to assess the presence of child abuse) were administered. RESULTS: The study was completed with 64 patients. Twenty-six percent of patient (n = 17) were diagnosed with juvenile fibromyalgia, and central sensitization was detected in 34.4% (n = 22). Pain intensity, anxiety, depression and abuse scores were higher in patients with juvenile fibromyalgia than those without juvenile fibromyalgia and in patients with central sensitization compared to those without central sensitization (p < 0.001 for both). Higher scores of pain were related with child abuse [beta = 0.763, p < 0.001, (%95 CI, 4.397; 8.841)] and central sensitization of pain [beta = 0.382, p = 0.008 (95% CI: (0.986;6.231)] in regression analyses. CONCLUSION: In this study, juvenile fibromyalgia was detected as a cause of non-cardiac chest pain. Juvenile fibromyalgia or central sensitization may also indicate childhood abuse.

Association of vitamin D deficiency with ventricular repolarization abnormalities.

BACKGROUND: Vitamin D is involved in cardiac contractility and myocardial calcium hemostasis, and vitamin D deficiencies are known to cause various cardiovascular disorders and have been linked with sudden cardiac death. AIM: The aim of the study was to evaluate repolarization distribution, represented by QT interval, corrected QT interval (QTc), QT dispersion, Tpeak­to­Tend (Tp­e) interval, Tp­e/QTc ratio, JT interval, JT dispersion, and Tp­e/JTpeak ratio in children with vitamin D deficiency. Moreover, we aimed to determine the relationship between ventricular repolarization anomalies and vitamin D deficiency. METHODS: The study included 50 adolescent patients with vitamin D deficiency (vitamin D <20 ng/ml), 50 adolescent patients with vitamin D insufficiency, and 50 age­matched controls (vitamin D level >30 ng/ml). QTc duration, QT dispersion, JTpeak duration, JT dispersion, Tp­e, Tp­e/JTpeak ratio, and Tp­e/QTc ratio were recorded on electrocardiogram. RESULTS: Patients with vitamin D deficiency or insufficiency had longer Tp­e interval (P <0.001), while Tp­e/QTc and Tp­e/JTpeak ratios were found to be increased in the same group of patients (P = 0.005 and P <0.001, respectively). QT dispersion and JT dispersion were higher in the deficient group when compared with the other groups (P = 0.045 and P = 0.02, respectively). CONCLUSION: The present study, conducted in a pediatric population, is the first in the current literature to assess the relationship between ventricular repolarization anomalies and vitamin D deficiency.

Analysis of the Factors Related to the Blood Pressure Control in Hypertension.

OBJECTIVE: To determine the factors associated with blood pressure control and comparing anthropometric and clinical parameters of subjects with well-controlled hypertension to those with poorly controlled blood pressure. STUDY DESIGN: Observational cross-sectional study. PLACE AND DURATION OF STUDY: Abant Izzet Baysal University Hospital, Bolu, Turkey, from January to June 2016. METHODOLOGY: Medical data obtained and recorded from computerised database and case files of our clinic. Subjects with mean blood pressure above target levels were defined as poorly controlled and others were as well-controlled hypertension group according to JNC VIII. RESULTS: Out of 342 subjects, only 116 (33.9%) were aware of normal blood pressure range. The number of patients who had a blood pressure on goal in the group and knew the normal range of blood pressure was significantly higher than the patients in group who did not know the normal range of blood pressure. Body mass index and waist circumference were both significantly higher in poorly controlled compared to well-controlled hypertensive subjects. Treatment compliance was significantly associated with better control of hypertension. CONCLUSION: Striking results of present study indicate that lower body mass index and lesser waist circumference along with treatment compliance and awareness of normal blood pressure ranges are important factors that affect reaching treatment targets in hypertensive subjects.

Partial trisomy 18q11.2-->qter due to de novo unbalanced translocation of chromosomes 15 and 18 analyzed by fluorescence in situ hybridization.

This report presents a case with partial trisomy 18q resulting from de novo unbalanced translocation of chromosomes 15 and 18 displaying the features of pure trisomy. This is the first reported case with partial trisomy 18q due to unbalanced translocation between chromosomes 15 and 18. Clinical findings of our case have been compared with the reported cases' had partial trisomy 18q and the importance to recognize the cases with chromosome abnormalities to give genetic counseling and prenatal diagnosis for subsequent pregnancies has emphasized.
