Serum prolidase enzyme activity and oxidative stress levels in patients with acute hemorrhagic stroke.

BACKGROUND: It has been indicated that oxidative damage contributes to secondary brain injury in both ischemic and hemorrhagic stroke patients. Collagen is a major component of the extracellular matrix, and prolidase plays a role in collagen synthesis. The aim of this study was to evaluate the serum prolidase activity, nitric oxide (NO) levels, total antioxidant capacity (TAC) and total oxidant status (TOS) in patients with acute hemorrhagic stroke. METHODS: Twenty-five patients with acute hemorrhagic stroke and 25 controls were enrolled. Serum prolidase activity, catalase activity, NO levels, TAC and TOS were measured spectrophotometrically. Oxidative stress index (OSI) was calculated. RESULTS: Serum TAC levels and catalase activity were significantly lower in acute hemorrhagic stroke patients than controls (both, p < 0.001), while NO levels, TOS levels, OSI values and prolidase activity were significantly higher (all, p < 0.01). When patients with acute hemorrhagic stroke were divided according to gender, no differences were observed between females and males in respect to serum prolidase enzyme activity, NO levels, TAC levels, TOS levels and OSI values (all, p > 0.05). CONCLUSIONS: Findings from the study suggest an association between increased oxidative stress levels, decreased antioxidant levels and increased prolidase enzyme activity in patients with acute hemorrhagic stroke compared with controls. More studies are needed to elucidate mechanistic pathways on oxidative stress in patients with acute hemorrhagic stroke.

Cerebral venous sinus thrombosis presentation in emergency department in Van, Turkey.

OBJECTIVE: To exmaine the distribution of age, gender, time between onset and presentation, clinical findings, predisposing factors, platelet distribution width, mean platelet volume values and neuroimaging findings, together with the treatment regime and the outcome for patients of cerebral venous sinus thrombosis. METHODS: The retrospective, descriptive cross-sectional study was conducted at Yuzuncu Yil University, Medical Faculty Hospital in Van, Turkey, comprising 51 cases diagnosed with cerebral venous sinus thrombosis between January 2008 and September 2011. The diagnosis was based on the results of clinical evaluation, cranial magnetic resonance imaging and venography. SPSS 16 was used for statistical analysis. RESULTS: Overall, 43 (84.3%) of the cases were female, and 8 (15.7%) were male.The average age was 32 +/- 11.13 years The most frequent symptom was headache in 41 (80.4%) cases. The postpartum period was one of the most observed predisposing factors in 17 (33.3%) patients. The magnetic resonance imaging was normal in 35 (68.6%) cases, but in all of the cases, magnetic resonance venography was abnormal. Topographically, the most frequent involvement was transverse sinus in 40 (78.4%) cases. Besides, 50 (98%) patients were discharged following full recovery or mild sequela and only 1 (2%) case had severe sequela. CONCLUSION: Patients presenting with headache should be examined carefully in the emergency department. Early diagnosis and treatment with clinical and neuroimaging techniques for such patients is recommended.

Anti-CCP antibody levels are not associated with MS: results from a case-control study.

Citrullinated proteins have been suggested to play a critical role in the pathogenesis of multiple sclerosis (MS). Anticyclic citrullinated peptide (anti-CCP) antibody is used in the early diagnosis of rheumatoid arthritis (RA). The objective of this study was to investigate the presence of anti-CCP antibody in patients with MS compared to RA patients and healthy controls. Fifty patients with MS (38 females, 12 males; mean age 36.72 ± 8.82 years), 52 patients with RA (40 females, 12 males; mean age 40.87 ± 10.17 years), and 50 healthy controls (32 females, 18 males; mean age 38.22 ± 11.59 years) were included in this study. The levels of serum anti-CCP antibody were measured using an enzyme-linked immunosorbent assay (ELISA). The results of the study showed that anti-CCP antibody levels were significantly higher in RA patients versus MS or healthy controls (P < 0.001). Moreover, anti-CCP antibody was positive in 43 (83%) patients with RA, while it was negative in all MS patients as well as in all healthy controls. Also, no significant correlation was found between the anti-CCP levels and EDSS scores (r = -0.250). In conclusion, the results of this study did not support a positive association between serum anti-CCP antibody and MS.

Coping strategies and mood profiles in patients with multiple sclerosis.

OBJECTIVE: The aim of the present study was to investigate the coping strategies, mood characteristics and the association between these aspects in patients diagnosed with multiple sclerosis and healthy subjects. METHOD: Fifty consecutive patients who were diagnosed with multiple sclerosis according to McDonald criteria and thirty-one healthy subjects were included in the study. In addition to the sociodemographic form, Expanded Disability Status Scale (EDSS), Coping Orientation for Problem Experiences Scale (COPE), and Profile of Mood States (POMS) tests were applied to the participants. RESULTS: Non-functional coping strategies were significantly higher in the secondary-progressive type (p≤0.05). Depression-dejection, fatigue-inertia and total POMS scores were significantly higher in the secondary-progressive type (p≤0.05). CONCLUSION: The results of our study demonstrate the importance of rehabilitation programs that encourage exercise among patients with multiple sclerosis to increase vigor-activity levels.

Ischemic bilateral opercular syndrome.

Opercular syndrome, also known as Foix-Chavany-Marie syndrome, is a paralysis of the facial, pharyngeal, masticatory, tongue, laryngeal, and brachial muscles. It is a rare cortical form of pseudobulbar palsies caused by vascular insults to bilateral operculum. Its clinical presentations include anarthria, weakness of voluntary muscles involving face, tongue, pharynx, larynx, and masticatory muscles. However, autonomic reflexes and emotional activities of these structures are preserved. In the present case, an 81-year-old male presented with acute onset of anarthria with difficulties in chewing, speaking, and swallowing that was diagnosed with opercular syndrome.

Coping strategies and mood profiles in patients with multiple sclerosis / Estratégias de enfrentamento e perfis de humor em pacientes com esclerose múltipla

Objetivo: Investigar as estratégias de enfrentamento, as características de humor e a associação entre estes aspectos em pacientes com diagnóstico de esclerose múltipla em comparação a indivíduos saudáveis. Método: Foram incluídos no estudo 50 pacientes com diagnóstico de esclerose múltipla de acordo com os critérios de McDonald e 31 pessoas saudáveis. Além da caracterização sócio-econômica, foram aplicados a todos os pacientes testes para avaliar o Expanded Disability Status Scale (EDSS), o Coping Orientation for Problem Experiences Scale (COPE) e o Profile of Mood States (POMS). Resultados: Escores referentes a estratégias de enfrentamento não funcionais foram significativamente maiores na forma secundariamente progressiva (p≤0.05). Escores relativos a depressão-abatimento, fadiga-inércia e escores totais POMS foram significativamente maiores na forma secundariamente progressiva (p≤0.05). Conclusão: Os resultados deste estudo mostram a importância de programas de reabilitação que encorajem os pacientes com esclerose múltipla a praticar exercícios com maiores níveis de vigor e atividade. .
