Inflammation and the Association of Vitamin D and Depressive Symptomatology

Depression and vitamin D deficiency are major public health problems. The existing literature indicates the complex relationship between depression and vitamin D. The purpose of this study was to examine whether this relationship is moderated or mediated by inflammation. A community sample (n = 7162) from the LIFE-Adult-Study was investigated, for whom depressive symptoms were assessed via the German version of CES-D scale and serum 25-hydroxyvitamin D (25(OH)D) levels and inflammatory markers (IL-6 and CRP levels, WBC count) were quantified. Mediation analyses were performed using Hayes’ PROCESS macro and regression analyses were conducted to test moderation effects. There was a significant negative correlation between CES-D and 25(OH)D, and positive associations between inflammatory markers and CES-D scores. Only WBC partially mediated the association between 25(OH)D levels and depressive symptoms both in a simple mediation model (ab: −0.0042) and a model including covariates (ab: −0.0011). None of the inflammatory markers showed a moderation effect on the association between 25(OH)D levels and depressive symptoms. This present work highlighted the complex relationship between vitamin D, depressive symptoms and inflammation. Future studies are needed to examine the effect of vitamin D supplementation on inflammation and depressive symptomatology for causality assessment.     

Radiological and clinical comparisons of the patients with rheumatoid arthritis operated with rigid and dynamic instrumentation systems due to lumbar degenerative spinal diseases

BackgroundIt is extremely difficult to treat spine disorders with stabilization in patients with rheumatoid arthritis. Because revision rates are significantly higher in rigid stabilization. To date, there is no data about patients with rheumatoid arthritis treated with dynamic stabilization. Our aim was to compare the radiological and clinical results of patients with rheumatoid arthritis who underwent lumbar rigid stabilization or dynamic stabilization with Polyetheretherketone rod (PEEK).MethodsPatients with degenerative lumbar spine disease with rheumatoid arthritis who underwent dynamic stabilization between 2013 and 2015 and rigid stabilization between 2010 and 2012 were evaluated radiologically for adjacent segment disease, proximal junctional kyphosis, system problem (nonunion, screw loosening, instrumentation failure, pull out). It was also compared according to both the revision rates and the Visual Analog Scale and Oswestry Disability Index scores at the 12th month and 24th month.ResultsThe difference of decrease in Visual Analog Scale and Oswestry Disability Index scores from preoperative to 12th month between patients who underwent dynamic stabilization and rigid stabilization was statistically insignificant. However, there was a significant difference of increase in Visual Analog Scale and Oswestry Disability Index scores between the 12th month and 24th month of patients who underwent rigid stabilization, compared with patients with dynamic stabilization. In patients with dynamic stabilization, the problems of instrumentation were seen less frequently. Revision rates were high in patients with rigid stabilization when compared the patients with dynamic stabilization.ConclusionRadiological and clinical outcomes in patients with rheumatoid arthritis operated with dynamic stabilization are more significant when compared to rigid stabilization. These patients have lower pain and disability scores in their follow up periods. Revision rates are lower in patients with dynamic stabilization.     

Multiple Giant Aneurysms and Stenoses of the Coronary and Systemic Arteries in an Infant with Kawasaki Disease at the Early Stage of Convalescent Period

Myocardial infarction and systemic arterial aneurysms are rarely seen during the course of the Kawasaki disease (KD). Herein, we report the case of a 4‐month‐old Turkish infant who was diagnosed with KD on the 17th day of the illness. On admission, echocardiogram showed multiple coronary arterial aneurysms (CAAs) and massive pericardial effusion. He was given intravenous immunoglobulin, aspirin and anticoagulant drugs. However, the aneurysms progressed to “super giant” CAAs, multiple huge coronary arterial thromboses developed recurrently and caused myocardial ischemia. Furthermore, the conventional angiography revealed multiple giant aneurysms and stenoses in the subclavian, celiac, and iliac arteries, besides CAAs.     

Where is the right ventricle? Accurate diagnosis with cardiovascular multimodality imaging

Endomyocardial fibrosis (EMF) is a globally unattended disease with significant rates of morbidity and mortality. It has a higher prevalence in tropical and subtropical countries compared to the rest of the world. Endomyocardial fibrosis can affect the atrioventricular valves, along with all four chambers of the heart, but spares the myocardium. Patients currently undergo symptomatic treatment with diuretics and vasodilators to enhance quality of life, although medical therapy alone is associated with poor prognosis. Hence, patients with severe symptoms prefer surgical treatment. Modern multimodality imaging, however, can help these definitions to be made more accurately.     

Ischemia-modified albumin levels in children having seizure

Convulsions are one of the frequently seen problems for a neurologist in the daily routine. It is difficult to distinguish the seizure from pseudo-seizure because of lack of conclusive tests. The aim of this study is to investigate the relationship between seizure types and seizure periods by studying IMA serum levels in children having seizure. Two groups were included (patients and control) in our study. The patient group consisted of the children admitted to Pediatric Emergency Care during January 2008–January 2010 with seizure and the control group consisted of healthy children. Serum Ischemia modified albumin (IMA) level in the group having seizures was 99.7 and 83.2 U/ml in the control group. In the comparison of the patient and control groups, significant differences were found between their IMA values (p = 0.000). There was a significant difference between IMA values of the group having generalized tonic–clonic seizures and those of the control group (p = 0.001). In comparison of the IMA values of the group having febrile convulsions and those of the control group, a significant difference was determined (p = 0.011). It has been shown that if the seizure was prolonged over 5 min, IMA level increased, and there was a significant difference between the groups experiencing over 5 min of seizures and the groups experiencing less than 5 min of seizures (p = 0.001). An increase in IMA levels in febrile convulsion supports the hypoxia development in the brain during the seizure. Serum IMA levels increased with the elongation of the seizure period and may be an indicator for status epilepticus.

Diabetic neuropathies

Diabetic neuropathies are the most common type of neuropathies seen in clinical practice. These neuropathies can range clinically from asymptomatic to manifesting symptoms caused by motor, sensory, and autonomic nerve dysfunction. These neuropathies can affect the peripheral nervous system, pain receptors, cardiovascular, urogenital, and gastrointestinal systems. This monograph presents an overview of the different types of diabetic neuropathies, their presentations, diagnostic tools, and strategies for management.     

Early stage epithelial ovarian cancers: A study of morphologic prognostic factors

We intended to reevaluate the morphologic prognostic factors for early-stage ovarian carcinomas. We reviewed 111 patients diagnosed with early-stage ovarian cancer who had undergone primary surgery at Hacettepe Hospital between 1984 and 2001, using diagnostic criteria from the WHO-2003 classification. We applied the Universal grading system suggested by Shimizu/Silverberg and noted FIGO-stage, histotype, tumor size, bilaterality, and endometriosis. These features were compared with each other and survival. The survival analysis was carried out by Kaplan–Meier curves. Of the cases, 52 were reclassified as ‘borderline tumor’ or ‘cystadenoma with borderline foci’ and 59 as ‘invasive carcinoma’. FIGO-stage and mitotic count were significant for survivals of 59 patients with cancer. Mitotic index was also significant for the probability of metastasis. The patients with stage-II cancer had 5.65 times more risk of recurrence than stage-I cancer. The 5-year overall and disease-free survivals rates were 90.6% and 87.5% for stage-I, 54.7% and 39.3% for stage-II, respectively. Universal grade did not reach statistical significance for survivals but it was related to FIGO-stage significantly. In conclusion, FIGO-stage is the most reliable prognosticator. Although prognostic value of universal grade is not significant, mitotic count may provide important prognostic information for early-stage ovarian carcinomas.
