RESUMEN
STUDY DESIGN: A total of 110 patients with scoliosis were enrolled in this analytical cross-sectional study. PURPOSE: We aimed to compare the urodynamic study (UDS) results of patients with idiopathic scoliosis (ISC) and congenital scoliosis (CSC) and to evaluate the clinical significance of abnormal UDS findings in predicting underlying tethered cord syndrome (TCS). OVERVIEW OF LITERATURE: An abnormal UDS finding is commonly found in patients with CSC. However, there is no consensus regarding its prevalence in patients with ISC. METHODS: Using the STROBE checklist for cross-sectional studies, 110 patients with scoliosis were selected based on our inclusion and exclusion criteria. Among the patients, 76 presented with ISC and 34 with CSC. Demographic data and other details, such as the results of spine radiography, UDS, and magnetic resonance imaging of the spine in both supine and prone positions, were recorded and analyzed. RESULTS: Approximately 50% of patients with CSC had normal UDS findings; 8.8%, mild impairment; and 41.2%, significant abnormalities. Moreover, 67.1% of patients with ISC had normal UDS findings; 9.2%, mild impairment; and 23.7%, significant abnormalities (p =0.166). TCS was identified in 38.2% and 26.3% of patients with CSC and ISC, respectively (p =0.571). In patients with ISC, a significantly abnormal UDS finding indicated that the risk of TCS increased from 26.3% to 50% (odds ratio [OR], 4.2; p =0.009). Meanwhile, in patients with CSC, the risk was almost similar (OR, 0.8; p =0.8). CONCLUSIONS: Even with the absence of subjective urinary symptoms, subclinical urologic impairments can be observed in a significant number of patients with ISC. An abnormal UDS finding can be a sign of underlying spinal cord tethering in a patient with ISC who is a candidate for corrective spine surgery even though it is an independent variant and is not exclusive to candidates for surgery. This finding has high clinical utility for neuro- and ortho-spine surgeons who aim to correct scoliosis (OR, 4.2; p =0.009).
RESUMEN
BACKGROUND AND OBJECTIVES: Child abuse with sewing needle is a rare but well-known homicide attempt threatening the life of victims. Information about diagnosis and treatment of such cases either in the acute or chronic phases is lacking and ambiguous in the literature. This study intends to report the experience of 6 victims of homicide attempt who presented to the authors in different decades of life and were managed in different ways. This may deliver some evidences to the literature regarding management of further cases encountered by neurosurgeons. MATERIAL AND METHODS: The authors had the chance of managing 6 patients referred to their trauma center harboring one or more sewing needles within their cranium. There were 3 male and 3 female patients, with 2 patients in their first decade of life, and the others, each in either decade of life. The youngest was 6, and the eldest 51 year old. The elder patients were having vague headaches, for which a plain skull x-ray or CT of the brain lead to the diagnosis of persisting intracranial foreign bodies. Chronic headache was the main complaint of the patients. Four patients underwent surgical removal of the sewing needle, and 2 are being followed. RESULTS: Among the 4 patients who underwent surgery, 1 died after a short period of 'akinetic mutism.' Headache and limb paresthesia improved 6 months after the operation in 2 cases, and the other 1 remained unchanged. The cases under observation have been doing well. Biochemical analysis of the rusted needle showed a composite of oxidant form of some of the elements of needle such as Fe, Mn, and Cr. CONCLUSION: In spite of standard algorithms proposed for management of penetrating head wounds, selection of the best treatment in the victims harboring sewing needles in their brain needs close cooperation between neurosurgeons, pediatricians, psychiatrists, and social workers. Furthermore, there is no absolute indication for removing sewing intracranial needles detected in the later decades of life.

BACKGROUND: Los Angeles classification is widely adopted for reporting endoscopic gastroesophageal reflux disease. We assessed the inter- and intra-observer variability of the Los Angeles classification. METHODS: Still images (n = 254) of the lower esophagus were presented to 9 gastroenterologists (6 experts and 3 trainees) and they were asked to report the images according to the Los Angeles classification. After 2 weeks the images were reordered and they were asked to report them again. Kappa statistic was calculated for intra- and inter-observer variability. RESULTS: The kappa for intra-observer agreement was 0.54 (attendings: 0.54; trainees; 0.55; P = not significant) and the inter-observer agreement was 0.22 (attendings: 0.20; trainees: 0.31; P = 0.027). The inter- and intra-observer kappa values in differentiating nonerosive from erosive cases were 0.22 (attendings: 0.21; trainees: 0.31, P = not significant) and 0.57 (attendings: 0.58; trainees: 0.55, P = not significant), respectively. CONCLUSION: According to our data, the Los Angeles classification has acceptable intra-observer variability, both for detecting presence or absence of erosions and for differentiating between different degrees of esophagitis, while its inter-observer performance seems to be less acceptable. It may be reasonable and timely to have another look at the Los Angeles classification to see whether its performance can be improved even further.
