The relation between serum inflammatory marker levels and serous retinal detachment in macular edema secondary to retinal vein occlusion.

PURPOSE: To assess blood-derived inflammatory markers in macular edema (ME) secondary to retinal vein occlusion (RVO) with and without serous retinal detachment (SRD). MATERIALS-METHODS: Treatment-naive patients with ME secondary to RVO were divided into two groups according to the existence of SRD in optical coherence tomography (OCT) images; group 1 consisted of 60 patients with SRD, and group 2 consisted of 60 patients without SRD. Age and gender-matched 60 patients formed group 3 as healthy controls. Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic inflammation index (SII) were calculated from blood samples to assess the differences in the levels of blood-derived inflammatory markers and the presence of SRD. RESULTS: The PLR, NLR, and SII values were higher in groups 1 and 2 than in group 3 (p<0.05, each comparison). The NLR and SII values were also significantly elevated in group 1 compared to group 2 (p = 0.000 and p = 0.000, respectively). The optimal cutoff value to estimate SRD in patients with ME secondary to RVO for NLR was 2.08 with 66.7% sensitivity and 65% specificity; for SII was 530.93 with 68.3% sensitivity and specificity. CONCLUSION: SII is a reliable and cost-effective tool for predicting SRD, an inflammatory OCT biomarker in ME secondary to RVO.

Prevalence of idiopathic intracranial hypertension and associated factors in obese children and adolescents.

BACKGROUND: Idiopathic intracranial hypertension (IIH) is one of the most important and rare complications of obesity. Prevalence of IIH in childhood obesity is not known. The purpose of this study was to determine the prevalence of IIH in obese children and adolescents and to investigate the relevant factors. METHODS: In this study, 1058 obese children and adolescents between 2 and 18 years of age were included. Funduscopic examination was conducted for all subjects. In cases with papilledema, increase in intracranial pressure was clarified by measuring CSF pressure with a lumbar puncture. Other causes of IIH were ruled out with clinical, laboratory tests and imaging techniques. RESULTS: Idiopathic intracranial hypertension was diagnosed in 14 subjects (1.32%). Rates of headache and systemic hypertension in subjects with IIH was determined to be 78.6% and 28.6%, respectively. Morning cortisol, fasting insulin and HOMA-IR values were found to be significantly higher in this cases (p<0.05). CONCLUSIONS: In childhood obesity, IIH should be kept in mind as a serious complication. Funduscopic examination is an easy method that suggests IIH. In particular, obese children with systemic hypertension and refractory headache should be considered for IIH.

Pseudotumor cerebri/idiopathic intracranial hypertension in children: an experience of a tertiary care hospital.

OBJECTIVE: Pseudotumor cerebri (PTC) is diagnosed at increasing rates probably due to the increase in obesity prevalence all over the world and awareness about the disease. Our aim in this study was to evaluate the PTC clinical picture and etiological factors in children at the present time. METHOD: The records of 53 patients with 32 females, who were diagnosed with PTC in a child neurology department between the years of 2005 and 2012 were retrospectively analyzed. RESULTS: The mean age at presentation was 10.9 years (3-17 years) and approximately half of patients were aged of 11 years or less. While more than half of prepubertal patients were male, girls rate reaches 74% at puberty. An etiological factor such as venous sinus thrombosis, infections, anemia, steroid discontinuation, drugs, slit ventricle syndrome and minor head injury causing the PTC was identified in 43% of the patients. The mean duration of treatment was 6.4 months (3-24 months) and the mean follow-up duration 16.5 months (3-52 months). Visual field constriction was moderate in only two pubertal and obese female patients and mild in four patients. CONCLUSIONS: PTC is seen in prepubertal children as often as in puberty. An etiological factor causing PTC is present in about half the patients in childhood. The main etiological factors of the disease currently consist of cranial venous thrombosis, infections, anemia and drugs. Malnutrition, renutrition and related vitamin deficiencies or excesses commonly seen previously have become less important in PTC etiology. PTC is a disease that requires long-term treatment and follow-up but the prognosis is good in patients who are diagnosed early, receive appropriate treatment and show good compliance with the treatment.
