    Breast-feeding-associated hypernatremia: Retrospective analysis of 169 term newborns
    (Wiley, 2008) Unal, Sevim; Arhan, Ebru; Kara, Nazli; Uncu, Nermin; Aliefendioglu, Didem
    Background: The aim of the present paper was to define the incidence, complications, morbidity and mortality of hypernatremic dehydration due to inadequate breast-feeding in a neonatal intensive care unit. Methods: A retrospective study was carried out between 2002 and 2005, to identify the term breast-fed neonates with serum sodium level >= 150 mEq/L at the Ministry of Health Ankara Diskapi Children's and Research Hospital. Results: The incidence of hypernatremic dehydration secondary to inadequate breast-feeding was 4.1%, occurring in 169 term infants among 4136 hospitalized term neonates with the following characteristics: mean gestational age, 39.1 weeks (37-42 weeks); birthweight, 3352 g (2200-4500 g); mother's age, 26.1 years (17-38 years); weight loss, 15.9% (5.4-32.7%); proportion of spontaneous vaginal deliveries, 75.7%; and proportion of first-time mothers, 74.6%. Major presenting symptoms were neonatal jaundice (47.3%) and poor infant suck (29.6%). The median sodium; blood urea nitrogen (BUN); and creatinine levels on admission were 155 mmol/L (150-194 mmol/L), 35 mg/dL (7-253 mg/dL), and 0.9 mg/dL (0.2-10 mg/dL), respectively. Major complications were as follows: acute renal failure, 82.8%; elevated liver enzymes, 20.7%; disseminated intravascular coagulation, 6.5%; brain edema, 5.2%; intracranial hemorrhage, 3.6%; cavernous sinus thrombosis, 1.2%; and bilateral iliac artery thrombosis, 0.6%. Ten patients (5.9%) developed seizure within the first 24 h of rehydration therapy with a mean sodium decrease of 11.9 mmol/L per day (4-19 mmol/L per day). Two patients (1.2%) died. There were positive correlation between weight loss and serum sodium, BUN, bilirubin levels (P < 0.01); there was no correlation between weight loss and mothers' age, education level, delivery route, or first-born status (P > 0.05). Conclusions: Hypernatremic dehydration in neonates due to inadequate breast-feeding is a serious, potentially devastating and life-threatening disorder, and can damage the central nervous system. Follow up of infants for adequate breast-feeding is important. Pediatricians must maintain a high level of suspicion, especially in cases of pathologic infant weight loss after delivery.

    Sacroiliitis in Children With Familial Mediterranean Fever
    (Lippincott Williams & Wilkins, 2019) Aydin, Fatma; Ozcakar, Z. Birsin; Cakar, Nilgun; Celikel, Elif; Uncu, Nermin; Acar, Banu Celikel; Yalcinkaya, Fatos
    Background/Objective Familial Mediterranean fever (FMF) is an autosomal recessive disease, characterized by recurrent, self-limited attacks of fever with serositis. Various diseases were reported to be associated with FMF. The aim of this study was to investigate the frequency and characteristics of sacroiliitis in children with FMF. Methods Files of FMF patients who had been seen in 2 reference hospitals in Ankara were retrospectively evaluated. Patients with FMF and concomitant sacroiliitis were included to the study. All patients had magnetic resonance imaging evidence of sacroiliitis. Results Among 650 FMF patients, 17 (11 females, 6 males; mean age, 13.32 +/- 4.24 years) (2.6%) of them were found to have sacroiliitis. Familial Mediterranean fever diagnosis was done prior to sacroiliitis diagnosis in 11 patients (65%) and concurrently or afterward in 6 patients (35%). Ten patients had isolated sacroiliitis, and 7 had associated diseases (5 enthesitis-related arthritis, 1 psoriatic arthritis, and 1 ulcerative colitis). Arthritis (59%), arthralgia (77%), leg pain (71%), heel pain (41%), and enthesitis (29%) were common complaints. Sacroiliac tenderness was detected in 77%, and M694V mutation in almost 90% of the patients. All patients received colchicine therapy. Additionally, 14 of them were treated with nonsteroidal anti-inflammatory drugs, 10 were on sulfasalazine treatment, and 7 of them were on biological agents. Conclusions Sacroiliitis can be seen in patients with FMF during childhood, and M694V mutation seems to be a susceptibility factor for its development. Inflammatory low-back pain and leg and heel pain could suggest sacroiliitis.
