AI Article Synopsis
- The study investigates the incidence of horizontal misalignment that requires surgery in children with congenital Brown syndrome, based on medical records from a specific medical center over 18 years.
- Among the 16 patients studied, most (88%) underwent surgery to correct compensatory head positions, with a notable portion also having primary position horizontal deviations.
- Post-surgery results showed a significant reduction in horizontal deviation, highlighting the need for addressing this issue during surgical intervention for congenital Brown syndrome.
Article Abstract
Purpose: To report the incidence of horizontal deviations requiring surgical correction in patients with congenital Brown syndrome.
Methods: In a retrospective study, the medical records of all children who underwent a surgical correction of congenital Brown syndrome at Schneider Children's Medical Center of Israel from 1998 to 2016 were reviewed, analyzing the presence of preoperative primary position horizontal misalignment.
Results: Overall, 19 eyes (8 right and 11 left eyes) of 16 patients (7 males, 9 females; mean age: 4.2 ± 2.6 years) were included in this study. Fourteen patients (88%) had surgery for correction of a compensatory head position, including 8 patients (50%) with a head tilt and 6 patients (38%) with a chin-up position, and 2 patients had surgery for primary position hypotropia. All of them underwent a weakening procedure of the superior oblique tendon, by either Z-tenectomy (81%, n = 13) or suture elongation of the superior oblique tendon (19%, n = 3). Fifty-six percent of patients (n = 9) had primary position horizontal deviation before surgery, including 50% (n = 8) exodeviations, ranging from exophoria of 4 prism diopters (PD) to exotropia of 30 PD, and one esotropia of 14 PD. Fifty percent of patients (n = 8) had surgery to correct the horizontal deviation by a recession of either one (31%, n = 5) or two (19%, n = 3) muscles. Mean preoperative horizontal deviation (9.3 ± 3.4 PD) decreased significantly following surgery (1.7 ± 1 PD, P = .001) (paired t test).
Conclusions: Significant horizontal misalignment is often present in patients with congenital Brown syndrome and its correction should be considered at the time of surgery. [J Pediatr Ophthalmol Strabismus. 2018;55(2):113-116.].

Successful outcome in synergistic divergence after unilateral lateral rectus recession and medial rectus resection.

Article Synopsis
- Synergistic divergence, or type IV Duane syndrome, is a congenital disorder marked by unusual eye muscle control leading to both eyes moving outward when trying to look to one side.
- A case study of a 23-year-old man highlighted his strabismus surgery to address a significant right exotropia and a left head turn developed for better vision since childhood.
- The surgery involved a combination of a 14 mm recession of the right lateral rectus and a 10 mm resection of the right medial rectus, suggesting this approach as an effective treatment for the condition.
Subsequent pregnancies in the IMPAACT 2010/VESTED Trial: high rate of adverse outcomes in women living with HIV.

Introduction: Women with HIV (WHIV) have higher risks of adverse pregnancy outcomes, particularly in the absence of antiretroviral treatment(ART), and timing of ART may impact risk.
Methods: In IMPAACT 2010 (VESTED), 643 pregnant WHIV in 9 countries were randomized 1:1:1 to initiate ART: dolutegravir (DTG)+emtricitabine(FTC)/tenofovir alafenamide(TAF); DTG+FTC/tenofovir disoproxil fumarate (TDF) or efavirenz (EFV)/FTC/TDF. We describe adverse pregnancy outcomes in women with a subsequent pregnancy during 50 weeks of postpartum follow-up: spontaneous abortion (<20 weeks), stillbirth (≥20 weeks), preterm delivery (<37 weeks) and small-for-gestational-age (SGA).

Diarrhea associated with enteric infections, gut inflammation, and genetic defects poses a major health burden and results in significant morbidity and mortality. Impaired fluid and electrolyte absorption and/or secretion in the intestine are the hallmark of diarrhea. Electroneutral NaCl absorption in the mammalian GI tract involves the coupling of Na/H and Cl/HCO exchangers.

Aims: This study explored the prospective use of the Ages and Stages Questionnaires-3 in follow-up after cardiac surgery.
Materials And Method: For children undergoing cardiac surgery at 5 United Kingdom centres, the Ages and Stages Questionnaires-3 were administered 6 months and 2 years later, with an outcome based on pre-defined cut-points: Red = 1 or more domain scores >2 standard deviations below the normative mean, Amber = 1 or more domain scores 1-2 standard deviations below the normal range based on the manual, Green = scores within the normal range based on the manual.
Results: From a cohort of 554 children <60 months old at surgery, 306 participated in the postoperative assessment: 117 (38.
Management of Neonatal Hyperinsulinemic Hypoglycemia: Trends Over Nine Years.

Background: With increasing use of diazoxide for hyperinsulinemic hypoglycemia (HH), reporting of serious side effects of diazoxide such as pulmonary hypertension (PHT) increased.
Methods: Charts of all children diagnosed with HH during the study period and evaluated by Pediatric Endocrinology division of the Hasbro Children's Hospital were reviewed. We analyzed diazoxide use among infants with HH with focus on infants born small for gestational age (SGA) and preterm infants.
