STUDY DESIGN: Retrospective analysis. PURPOSE: To evaluate the effectiveness of anterior cervical discectomy with fusion for degenerative cervical disc disease. OVERVIEW OF LITERATURE: Anterior spinal surgery originated in the mid-1950s and graft for fusion was also employed. Currently anterior cervical microdiscectomy and fusion with an intervertebral cage is a widely accepted procedure for treatment of cervical disc hernia. Artificial grafts and cages for fusion are preferred because of their lower morbidity, reduced operating time and acceptable fusion rate. METHODS: The study involved retrospective analysis and investigation of long-term results for 41 consecutive patients who had undergone anterior cervical discectomy and fusion with an intervertebral cage for cervical disc hernia. The angle of lordosis, segmental height and range of motion were evaluated preoperatively and postoperatively at 1 month and 2 years. The clinical outcome was assessed by the visual analog scale and Odom's criteria. RESULTS: The angle of lordosis increased by 2.62degrees and the range of motion angle increased by 5.14degrees after the operation. The segmental height did not change. The visual analog scale and Odom's criteria scores decreased significantly after the operation. CONCLUSIONS: Using a cage in anterior cervical discectomy prevents segmental collapse, so the segmental height and the angle of lordosis are preserved and newly-developed pain does not occur.

Raynaud's phenomenon is a recurrent vasospastic condition with reducing in peripheral blood flow due to cold, or emotional stress. White, blue and red discolorations occur during the attacks. Serotonin reuptake inhibitors, psychostimulants, and aripiprazole are reported to be related with Raynaud's phenomenon. Risperidone is an atypical antipsychotic drug with dopaminergic and serotonergic effects. In children and adolescents, risperidone is used for bipolar disorder, tic disorders, conduct disorder, schizophrenia, symptoms of irritability and self-mutilation. Here we report a case of Raynaud's phenomenon associated with risperidone in a 12-year-old boy. Raynaud's phenomenon occurred two weeks after starting risperidone and disappeared after stopping risperidone.

The aim of this paper is to show that osteochondromas of the cervical vertebrae can cause myelopathy and neck pain.The reported etiology, diagnosis, treatment and differential diagnosis were reviewed. Osteochondromas may present as a solitary lesion with no genetic component or as multiple lesions as a part of a genetic disorder known as hereditary multiple exostosis. Osteochondromas of the spine are rarely encountered in clinical practice. These lesions are reported more commonly with neural compression in cases associated with hereditary multiple exostosis. The authors describe a unusual clinical manifestation of a solitary osteochondroma located in the right posterior arch of the atlas. Complete removal of the tumor was performed resulting in the relief of neck pain and spastic quadriparesis. Although unusual, osteochondromas of the cervical spine must be considered in patients with persistent neck pain and progressive symptoms of myelopathy. Computed tomography and magnetic resonance imaging in conjunction with plain radiograms is the neuroradiological modality of choice. The diagnosis and surgical excision of these tumors are important because they can cause spinal stenosis resulting in neural tissue compression and myelopathy.

Pisa syndrome, a rare dystonic reaction resulting from prolonged exposure to antipsychotic medications, is characterized by persistent dystonia of trunk muscles and abnormal posture. It is called Pisa syndrome, because the abnormal posture resembles the Leaning Tower of Pisa. Different from other types of dystonic reactions, Pisa syndrome is more prevalent in females and in older patients with organic brain changes. A 15-year-old male patient with mental retardation was admitted to pediatric neurology clinic for the complaint of abnormal posturing. He had been taking only risperidone for the last four years. Over the last month, the patient gradually developed tonic flexion of trunk and head toward left and was diagnosed with Pisa syndrome. In this paper, we aimed to discuss the association between risperidone use and Pisa syndrome in light of the available literature.

Serotonin syndrome (SS) is a potentially life-threatening condition associated with increased serotonergic activity in central nervous system and may occur during the use of serotonergic drugs. Although increasing frequency of serotonergic drug use in children, pediatricians, emergency medicine and pediatric intensive care specialists have not enough knowledge and experience about SS that is a potentially life-threatening condition. A 12-year-old girl patient was admitted to our emergency room with the history of involuntary contractions on her extremities and alteration of consciousness. Her physical examination showed agitation, hyperthermia, dilated pupils, tremor, increased deep tendon reflexes, positive spontaneous clonus, agitation, flushed skin and diaphoresis, excessive perspiration, and continuous horizontal ocular movements. The patient diagnosed as SS by clinical history, physical and laboratory findings. In this paper, we will discuss SS occurred in a 12-year-old girl after concurrent clomipramine and risperidone use.

Neuroleptic malignant syndrome (NMS) is a life-threatening idiosyncratic reaction that usually occurs after the administration of antipsychotic drugs. Antidepressants, benzodiazepines, and antiepileptic drugs are also suggested to be associated with NMS. It is believed to result from a dopaminergic blockade in the central nervous system. NMS is manifested by hyperthermia, muscle rigidity, autonomic dysfunction, altered mental status, leukocytosis, and elevated serum creatinine phosphokinase. Valproate is commonly used in the treatment of many psychiatric and neurologic disorders. Valproate can precipitate NMS, especially when used with antipsychotic drugs concurrently. A 17-year-old male patient, who presented with fever, muscular rigidity, confusion, sweating, and tachycardia was admitted to the emergency room. He had been taking only valproate for the last two months for bipolar disorder. His laboratory analyses revealed raised serum hepatic enzymes, creatinine phosphokinase, and myoglobin levels. Considering fever, rigidity, autonomic dysfunction, cognitive alteration, and high creatinine phosphokinase levels, the patient was diagnosed with NMS. In this paper, we aim to discuss the association between valproate and NMS.

Purpose: The main purpose of this study is to evaluate prognostic factors that affected the patients’ early (<30 days) and late (six months, one year, and overall) postoperative mortality following hip fracture surgery. Materials and Methods: This retrospective study included 515 patients older than 75 years old with surgically treated osteoporotic hip fracture. The demographic data, American Society of Anesthesiologists (ASA) classification, type of anesthesia, duration of hospital stay, and history of intensive care unit (ICU) stay were collected.An analysis of laboratory values was also performed to determine their relationship with mortality. The primary outcome was survival, determined as the time from the surgery to death or the end of the study. The patients were divided into four groups according to survival time: at the first month, six months, first year, and overall survival. An analysis of demographic and laboratory values was performed to determine their validity as prognostic factors for each group. Results: Postoperative C-reactive protein (CRP) level showed an independent association with a poor survival at the first month. ASA classification, admission to the ICU, and preoperative CRP levels showed an independent association with a poor survival for the first six months. Preoperative CRP level showed an independent association with a poor survival for the first year. ASA classification, admission to the ICU, and the preoperative CRP levels showed an independent association with a poor overall survival. Conclusion CRP level, a high ASA classification, and postoperative ICU admission were related to poorer overall survival rate following hip fracture surgery in the elderly.

BACKGROUND/AIMS: Poor sleep quality (SQ) is associated with increased cardiovascular mortality and morbidity. Additionally, asymmetric dimethylarginine (ADMA) is an independent predictor of cardiovascular mortality and morbidity. However, no sufficient data regarding the relationship between ADMA levels and SQ have been reported. The goal of the current study was to evaluate the association between SQ and ADMA levels in normotensive patients with type 2 diabetes mellitus. METHODS: The study participants consisted of 78 normotensive type 2 diabetics. The SQ of all participants was assessed using the Pittsburgh Sleep Quality Index (PSQI). Patients with a global PSQI score > 5 were defined as "poor sleepers." Factors associated with poor SQ were analyzed using a multiple regression model. Serum ADMA levels were measured using high performance liquid chromatography. RESULTS: The median ADMA levels of the poor sleepers were increased compared with patients defined as good sleepers (5.5 [4.2 to 6.6] vs. 4.4 [2.9 to 5.4], p < 0.01, respectively). However, the L-arginine/ADMA ratio was decreased in poor sleepers (p < 0.01). Global PSQI scores were positively correlated with ADMA levels (p < 0.01) and negatively correlated with the L-arginine/ADMA ratio (p = 0.02). ADMA levels were correlated with sleep latency (p < 0.01) and sleep efficiency (p = 0.01). Logistic regression analysis showed that ADMA levels (odds ratio [OR], 1.68; 95% confidence interval [CI], 1.16 to 2.44; p = 0.01) and body mass index (OR, 1.15; 95% CI, 1.01 to 1.31; p = 0.04) were associated with poor SQ independently of glomerular filtration rate, sex, age, duration of diabetes, hemoglobin A1c, total cholesterol, and systolic blood pressure. CONCLUSIONS: Self-reported SQ was independently associated with ADMA levels in normotensive patients with diabetes mellitus.

Objective: To investigate the effects of probiotic bacteria on cisplatin (CP)-induced nephrotoxicity. Methods: In the present study, 50 Sprague-Dawley rats were used and randomly divided into five groups including control, CP, probiotic bacteria treatment groups with different doses (0.5 and 1 mL) and only probiotic bacteria group. After CP and probiotic administration on seven days, rats sacrificed under anesthesia on the eighth day. The serum urea, creatinine, and blood urea nitrogen levels were analyzed. In renal tissue, malondialdehyde levels, superoxide dismutase and glutathione activity, interleukin-8, interleukin-1β and tumor necrosis factor-alpha levels were determined and histopathological and immunohistochemical changes were also examined. Results: According to results, urea, creatinine and blood urea nitrogen levels as well as kidney weights increased in CP group. Also, CP induced inflammation, oxidative stress, DNA damage and apoptosis in kidney tissue and caused histopathological changes. Administration of the high dose of probiotic bacteria could prevent these changes and damages. Conclusions: This study reveals that probiotic bacteria has protective effects on CP-induced renal damage in rats.

Objective: To explore the possible effects of naringin on acrylamide-induced nephrotoxicity in rats. Methods: Sprague-Dawley rats weighing 200-250 g were randomly divided into five groups. The control group was given intragastric (i.g.) saline (1 mL) for 10 d. The acrylamide group was given i.g. acrylamide in saline (38.27 mg/kg titrated to 1 mL) for 10 d. The treatment groups were administered with naringin in saline (50 and 100 mg/kg, respectively) for 10 d and given i.g. acrylamide (38.27 mg/kg) 1 h after naringin injection. The naringin group was given i.g. naringin (100 mg/kg) alone for 10 d. On day 11, intracardiac blood samples were obtained from the rats when they were under anesthesia, after which they were euthanized. Urea and creatinine concentrations of blood serum samples were analyzed with an autoanalyzer. Enzyme-linked immunosorbent assay was used to quantify malondialdehyde, superoxide dismutase, glutathione, glutathione peroxidase, catalase, tumor necrosis factor-β, nuclear factor-κB, interleukin (IL)-33, IL-6, IL-1β, cyclooxygenase-2, kidney injury molecule-1, mitogen-activated protein kinase-1, and caspase-3 in kidney tissues. Renal tissues were also evaluated by histopathological and immunohistochemical examinations for 8-OHdG and Bcl-2. Results: Naringin attenuated acrylamide-induced nephrotoxicity by significantly decreasing serum urea and creatinine levels. Naringin increased superoxide dismutase, glutathione, glutathione peroxidase, and catalase activities and decreased malondialdehyde levels in kidney tissues. In addition, naringin reduced the levels of inflammatory and apoptotic parameters in kidney tissues. The histopathological assay showed that acrylamide caused histopathological changes and DNA damage, which were ameliorated by naringin. Conclusions: Naringin attenuated inflammation, apoptosis, oxidative stress, and oxidative DNA damage in acrylamide-induced nephrotoxicity in rats.
