Acute subdural hematoma: Outcome and outcome prediction

Patients with traumatic acute subdural hematoma were studied to determine the factors influencing outcome.Between January 1986 and August 1995, we collected 113 patients who underwent craniotomy for traumatic acute subdural hematoma. The relationship between initial clinical signs and the outcome 3 months after admission was studied retrospectively.Functional recovery was achieved in 38% of patients and the mortality was 60%. 91% of patients with a high Glasgow Coma Scale (GCS) score (9–15) and 23% of patients with a low GCS score (3–8) achieved functional recovery. All of 14 patients with a GCS score of 3 died. The mortality of patients with GCS scores of 4 and 5 was 95% to 75%, respectively. Patients over 61 years old had a mortality of 73% compared to 64% mortality for those aged 21–40 years. 97% of patients with bilateral unreactive pupil and 81% of patients with unilateral unreactive pupil died. The mortality rates of associated intracranial lesions were 91% in intracerebral hematoma, 87% in subarachnoid hemorrhage, 75% in contusion.Time from injury to surgical evacuation and type of surgical intervention did not affect mortality. Age and associated intracranial lesions were related to outcome. Severity of injury and pupillary response were the most important factors for predicting outcome.     

Prevalence study of signs and symptoms of temporomandibular disorders in a Turkish population

AIM: The aim of this study was to evaluate the prevalence of signs and symptoms of temporomandibular disorders (TMD) in a population of 792 Turkish adults ranging in age from 15- to 72-years-old. METHODS AND MATERIALS: Subjects were examined objectively and subjectively for signs and symptoms of TMD through the distribution of frequency of the data obtained from a questionnaire and a physical examination using a similar methodology of previous studies. RESULTS: This study determined the prevalence of signs and symptoms of TMDs in subjects from male and female subgroups in a Turkish adult population. Both signs and symptoms of TMDs were generally more prevalent in females than in males. CONCLUSION: The prevalence of signs and symptoms were generally greater than in previous studies of other populations.     

Using two ipsilateral double j ureteral stents for extrinsic ureteral obstruction due to colon carcinoma

Although double J (DJ) ureteral stents are widely used in extrinsic ureteral obstruction, there are few studies using ipsilateral two DJ stents in the same ureter. We report using ipsilateral two ureteral DJ stents in the same ureter in a patient with extrinsic ureteral obstruction due to colon carcinoma.     

Nephropathy and retinopathy in type 2 diabetic patients living at moderately high altitude and sea level

BACKGROUND: High-altitude-induced hypoxia results in various diseases, such as chronic mountain sickness and high altitude retinal edema, and may affect severity and incidence of some cardiovascular diseases. In order to evaluate the effects of moderately high altitude on diabetic nephropathy and retinopathy, a cross-sectional study was planned. MATERIAL METHOD: Long-term type II diabetic residents of sea level (n=75, 38 male, 37 female, mean age 51.9+/-10.5 in Trabzon and Zonguldak cities) and moderately high altitude (h = 1,727 m, n = 73, 28 male, 45 female, mean age 48.3+/-12.1, Van city) were compared. RESULTS: No difference was observed in terms of age, gender, diabetes duration, body mass index, smoking, systolic, diastolic, and mean arterial blood pressure values, serum glucose levels, cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, hemoglobin, HbA1C, hypertension control, or blood pressure medications and retinopathy incidence. Mean 24 h protein excretion (210.0+/-139.9, 127.8+/-112.1 mg; P=0.00), proteinuria prevalence (57.5% versus 33.3%, p=0.003), and serum creatinine levels (1.04+/-0.22 versus 0.84+/-0.21, p = 0.00) were significantly higher in the highlanders, glomerular filtration rate (GFR) was significantly lower in sea level (SL) patients (90.9+/-26.5 versus 83+/-21.1, p=0.05). CONCLUSION: Tendency to diabetic nephropathy as indicated by higher proteinuria and creatinine levels is increased among type 2 diabetic patients living at moderately high altitude. Prospective studies are needed to confirm these findings.     

Cervical spondylotic myelopathy and radiculopathy treated by oblique corpectomies without fusion

Oblique corpectomy (OC) is an alternative technique for the resection of spondylotic spurs ventral to the cervical spinal cord contributing to cervical spondylotic myelopathy (CSM) and cervical spondylotic radiculopathy (CSR). To evaluate the efficacy of OC for the treatment of cervical spondylotic myeloradiculopathy, we reviewed our experience with OC. Twenty-six patients, 18 males and 8 females, were studied. They averaged 51.3 years of age (range 30-72), Thirteen had myelopathy and 13, radiculopathy. Both magnetic resonance (MR) imaging and computed tomography (CT) were performed preoperatively to define the extent of pathology. The Modified Japanese Orthopedic Association (JOA) score was used to grade the quality of the outcome. Neurologic and radiologic results were assessed. Good and excellent results were observed in 76.9% of the cases with myelopathy. Improvement of radicular symptoms was noted in 84.6% of the cases with radiculopathy. Neuroimaging studies confirmed satisfactory anatomical decompression in all patients. Sagittal alignment decreased from 13 degrees to 12 degrees. The degree of postoperative recovery seemed to be directly related to the age and severity of the preoperative myelopathy. This surgical technique has shown excellent clinical outcomes with fast recovery and adequate anatomical decompression in patients with CSM and CSR.     

Computed tomographic evaluation of lumbar spinal structures during traction

In the previous studies, it is reported that traction diminishes the compressive load on intervertebral discs, reduces herniation, stretches lumbar spinal muscle and ligaments, decreases muscle spasm, and widens intervertebral foramina. The aim of this study was to evaluate the effects of horizontal motorized static traction on spinal anatomic structures (herniated area, spinal canal area, intervertebral disc heights, neural foraminal diameter, and m.psoas diameter) by quantitative measures in patients with lumbar disc herniation (LDH). At the same time the effect of traction in different localizations (median and posterolateral herniation) and at different levels (L4-L5 and L5-S1) was assessed. Thirty two patients with acute LDH participated in the study. A special traction system was used to apply horizontally-motorized static lumbar traction. Before and during traction a CT- scan was made to observe the changes in the area of spinal canal and herniated disc material, in the width of neural foramina, intervertebral disc heights, and in the thickness of psoas muscle. During traction, the area of protruded disc area, and the thickness of psoas muscle decreased 24.5% (p = 0.0001), and 5.7% (p = 0.0001), respectively. The area of the spinal canal and the width of the neural foramen increased 21.6% (p = 0.0001) and 26.7% (p = 0.0001), respectively. The anterior intervertebral disc height remained unchanged with traction however the posterior intervertebral disc height was significantly expanded. This study is the first to evaluated in detail and quantitatively the effect of motorized horizontal lumbar spinal traction on spinal structures and herniated area. According to detailed measures it was concluded that during traction of individuals with acute LDH there was a reduction of the size of the herniation, increased space within the spinal canal, widening of the neural foramina, and decreased thickness of the psoas muscle.
