The effects of fasting and dehydration on pupillary light reflex as detected by pupillometry.

The pupillary light reflex could serve as a valuable method for measuring dynamic responses in the autonomic nervous system (ANS). However, it remains unclear whether physiological conditions such as fasting and dehydration affect pupillary reflexes. In this study, we investigated the effects of fasting and dehydration on pupillary responses using pupillometry.

The effect of physician experience on the measurement reliability of the Reimers' hip migration percentage in children with cerebral palsy.

[Purpose] Reimers' hip migration percentage (MP) is commonly used to document the extent of hip displacement in children with cerebral palsy (CP). However, factors such as poor administration of pelvic radiographs, a lack of concentration, inexperience, or a busy clinical environment may result in variations in the MP measurements. The aim of this study was to compare the differences in the MP results of two physiatrists with varying levels of experience to determine the role of experience in the measurement's accuracy.

Effects of therapeutic ultrasound and exercise on pain, function, and isokinetic shoulder rotator strength of patients with rotator cuff disease.

[Purpose] The aim of this prospective, double-blind, randomized, placebo-controlled study was to evaluate the effects of therapeutic continuous ultrasound (US) on patients with rotator cuff disease. [Subjects and Methods] Twenty-two patients were treated with a standard physiotherapy program consisting of a hot-pack, transcutaneous electrical nerve stimulation (TENS), exercises, and US that was supervised by the same physiotherapist. The patients were randomly assigned to either a group that received true US (n=11) or one that received sham US (n=11).

The relationship between dry eye and migraine.

Presently, migraine and dry eye are both thought to have an inflammatory pathogenesis.

Autosomal Dominant Osteopetrosis Type II.

Osteopetrosis is a rare genetic disorder caused by osteoclast failure. Dominant negative mutations of the ClCN7 gene cause the so-called, autosomal dominant osteopetrosis type II, which represents the most frequent and heterogeneous form of osteopetrosis, ranging from asymptomatic to intermediate-severe, thus suggesting additional genetic and environmental determinants affecting penetrance. Here, we present a case a 46 year-old woman complained low back pain for 15 years.

Decreased serum vitamin D levels are associated with diabetic peripheral neuropathy in a rural area of Turkey.

Data examining the association between vitamin D and diabetic peripheral neuropathy are limited. This study investigated the serum levels of vitamin D, vitamin D-binding protein (VDBP), and vitamin D receptor (VDR) in diabetics in the Yozgat region of Turkey, and assessed their relationships with diabetic peripheral neuropathy. 69 diabetic patients and 49 age- and sex-matched control subjects were enrolled in this clinical prospective study.

Elevated neurofilament light chain (NFL) mRNA levels in prediabetic peripheral neuropathy.

Evidence suggests that peripheral nerve injury occurs during the early stages of disease with mild glycemic dysregulation. Two proteins, neuron-specific enolase (NSE) and neurofilament light chain (NFL), have been examined previously as possible markers of neuronal damage in the pathophysiology of neuropathies. Herein, we aimed to determine the potential value of circulatory NSE and NFL mRNA levels in prediabetic patients and in those with peripheral neuropathy.

Ischemic optic neuropathy after carotid body tumor resection.

Incidence estimates for postoperative vision loss after nonocular surgery range from 0.013% for all surgeries up to 0.2% following spine surgery.

S100B as a glial cell marker in diabetic peripheral neuropathy.

Evidence suggests that acute and chronic hyperglycemia can cause oxidative stress in the peripheral nervous system which, in turn, can promote the development of diabetic neuropathy. Recent studies have found increased expression of glial fibrillary acidic protein (GFAP) and S100B, both of which are indicators of glial reactivity, in the neural and retinal tissues of diabetic rats. For the first time in the literature, the serum levels of GFAP and S100B were assessed in patients with diabetes to evaluate the potential of these factors to serve as peripheral glial biomarkers of diabetes and to investigate their relationship to diabetic peripheral neuropathy.

Methods: This study included 34 patients who underwent ACL reconstruction in our clinic between November 2007 and March 2008. Eighteen patients (average age: 27.

Glucose regulation influences treatment outcome in ranibizumab treatment for diabetic macular edema.

Purpose: To evaluate the effect of glucose regulation on intravitreal ranibizumab injection for clinically significant diabetic macular edema (DME).

Methods: This retrospective study enrolled 65 eyes of 65 patients with persistent DME treated with intravitreal ranibizumab injection. The main outcome measures were the change in best corrected visual acuity (BCVA), the central subfield macular thickness (CSMT) recorded with optical coherence tomography (OCT), and its correlation with the serum hemoglobin A(1c) values (HbA(1c)).
