Posterior cranial fossa subdural hematomas and extension of the subdural hematoma to the cerebellopontine angle is rarely seen and the concurrent development of acute peripheral facial palsy and the management strategy have not previously been reported in this pathology because of its rarity. We present this case to emphasize that minor head trauma may lead to a posterior cranial fossa hematoma extending to the cerebellopontine angle and cause peripheral facial palsy in patients using aspirin (acetylsalicylic acid). In addition, partial evacuation and waiting for the resorption of the hematoma may help to prevent damage to the 7th and 8th cranial nerves.

OBJECTIVE: Bipolar disorder (BD) is a debilitating psychiatric disease with unknown etiology. Recent studies have shown inflammation as a potential contributing factor of BD pathogenesis. However, potential associations between chemokine and chemokine receptor polymorphisms and BD have been fundamentally understudied. To identify participation of chemokines in BD pathogenesis, we examined genetic variants of several chemokine and chemokine receptor genes. METHODS: The study population comprised 200 patients with BD and 195 age- and sex-matched healthy controls. Genotyping of monocyte chemotactic protein 1 (MCP-1) A2518G, CCR2 V64I, CCR5 Δ32, CCR5 A55029G, stromal cell-derived factor 1 (SDF-1) 3'A, and CXCR4 C138T polymorphisms was performed using polymerase chain reaction and restriction enzyme digestion. RESULTS: We found that CCR5-Δ32 II and CXCR4-C138T C+ genotype frequencies contributed to an increased risk for BD. However, no statistical significance could be obtained with these genotypes after Bonferroni correction. A significant asssociation was only found with MCP-1 GG and G+ genotypes, which were markedly more prevalent in patients with BD and these genotypes seemed to significantly increase the risk for BD even after Bonferroni correction. CONCLUSION: Our findings indicate an association between genetic variants of certain chemokine and chemokine receptor (especially MCP-1) genes and BD. The exact mechanisms by which these variants contribute to BD pathogenesis and their clinical implications need to be further investigated.

In this study, we investigated the effect of different values of intra-abdominal pressure on bacterial translocation. Twenty-four Wistar-Albino rats were divided into four groups. The animals belonging to the Control group were not subjected to any increased intra-abdominal pressure. In groups I, II and III, an intra-abdominal pressure of 14, 20, and 25 mmHg, respectively, was established by carbon dioxide pneumoperitoneum for a period of 60 minutes. Four hours after the pneumoperitoneum, all animals were sacrificed to evaluate the degree of bacterial translocation at this time. Liver, spleen and mesenteric lymph nodes were excised under sterile conditions. Bacterial growth was assessed using standard bacteriological techniques and compared statistically. The Kruskal-Wallis and Mann-Whitney U tests were used for the statistical analysis. Different amounts of bacterial growth were found in all of the animals subjected to increased intra-abdominal pressure, except for the controls. Bacterial translocation was detected at an intra-abdominal pressure of 14 mmHg but this finding was not statistically significant (p > 0.05). There was a significant increase in bacterial growth in animals subjected to an intra- abdominal pressure of 20 mmHg or above (p < 0.001). As a result, we found that bacterial translocation started when the intra-abdominal pressure reached a level of 14 mmHg. Patients should be closely monitored for septic complication risks following laparoscopic procedures in which the intra-abdominal pressure exceeds 20 mmHg.

Osteoblastomas are rare neoplasms of the spine. The majority of the spinal lesions arise from the posterior elements and involvement of the corpus is usually by extension through the pedicles. An extremely rare case of isolated C2 corpus osteoblastoma is presented herein. A 9-year-old boy who presented with neck pain and spasmodic torticollis was shown to have a lesion within the corpus of C2. He underwent surgery via an anterior cervical approach and the completely-resected mass was reported to be an osteoblastoma. The pain resolved immediately after surgery and he had radiologic assessments on a yearly basis. He was symptom-free 4 years post-operatively with benign radiologic findings. Although rare, an osteoblastoma should be considered in the differential diagnosis of neck pain and torticollis, especially in patients during the first two decades of life. The standard treatment for osteoblastomas is radical surgical excision because the recurrence rate is high following incomplete resection.

BACKGROUND AND PURPOSE: Multiple sclerosis (MS) is an autoimmune disease characterized by inflammatory demyelination. Recent studies have shown that long-term exposure to air pollutants (including PM10 particulates) is potentially an environmental risk factor for MS. We aimed to determine the prevalence rates of MS in two cities with different levels of air pollution. METHODS: This door-to-door population-based study was conducted between April 2014 and June 2015. Two cities were screened for the prevalence rates of MS: 1) Karabük, which borders an iron-and-steel factory, and 2) Akçakoca, which is a coastal city located in the same region. A validated survey form was used for screening MS. The 2010 McDonald Criteria were used for diagnosing MS. The patients were examined twice, first by a neurology assistant in the field and then by a senior neurologist in public health centers in the cities. RESULTS: The prevalence of MS was 95.9/100,000 in Karabük and 46.1/100,000 in Akçakoca. In total, 33 patients were diagnosed with clinically definite MS. The female/male ratio was 1.5, and 21 patients were diagnosed with relapsing-remitting MS, 9 with secondary progressive MS, and 3 with primary progressive MS. CONCLUSIONS: We found that the prevalence of MS was more than two fold higher in Karabük than in Akçakoca, which supports a link between air pollution and the pathogenesis of MS. However, larger etiological and epidemiological studies are needed to confirm this hypothesis.
