Assessment of Hematological Factors Involved in Development and Prognosis of Idiopathic Sudden Sensorineural Hearing Loss.

Objective:The aim of this study was to investigate the possible effects of routine hematological parameters on the development and prognosis of idiopathic sudden sensorineural hearing loss in patients applying to our clinic. Study design:A retrospective clinical study. SettingOne academic health center from 2008 to 2014. Patients and intervention:One hundred forty patients with sudden hearing loss and 132 healthy controls were included in the present study. Results:Patients having idiopathic sudden sensorineural hearing loss were divided into 2 subgroups based on whether they recovered (complete, partial, and slight recovery) (Group 1; n = 83, 59.3%) or not (Group 2; n = 57, 40.7%) during the follow-up term. Group 1, Group 2, and the controls differed statistically significantly in terms of neutrophil-to-lymphocyte ratio (P = 0.001), platelet-to-lymphocyte ratio (P = 0.001), lymphocytes % (P = 0.001), mean corpuscular hemoglobin (P = 0.019), mean corpuscular hemoglobin concentration (P = 0.015), platelet (P = 0.001), mean platelet volume (P = 0.001), platelet distribution width (P = 0.009), and glucose (P = 0.001). The study groups and the controls did not have any significant difference in terms of other laboratory parameters affecting the prognosis of Idiopathic sudden sensorineural hearing loss. Conclusions:The results the authors obtained showed that laboratory parameters such as lymphocyte, lymphocyte%, platelet, mean platelet volume, platelet distribution width, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration may be indicative for prognosis and treatment success in groups of patients suffering idiopathic sudden sensorineural hearing loss in whose etiology many factors play a role.

Nodular lymphocyte predominant Hodgkin's lymphoma in daily practice: A multicenter experience

Nodular lymphocyte predominant Hodgkins lymphoma (NLPHL) is a rare subtype of Hodgkins lymphoma. In this study, we aimed to investigate the clinical features and therapeutic outcomes of patients with NLPHL who were diagnosed at different institutes in Turkey.

Hemolytic Uremic Syndrome: Single Centre Experience

Introduction: Hemolytic uremic syndrome (HUS) is a clinical syndrome characterized by non-immune microangiopathic hemolytic anemia, thrombocytopenia, and acute renal failure. In this study, we aimed to evaluate patients diagnosed with HUS in our clinic. Method: Patients who were diagnosed with HUS as clinic and laboratory between August 2012 and October 2017 were included in our nephrology clinic. Biochemistry, haemogram, ANA, anti-Ds DNA, p-ANCA, c-ANCA, anti-GBM antibody, C3, C4 of patients were studied. In some cases, ADAMTS13 was studied and renal biopsy was performed. The demographic features, clinics, and treatments of our cases were reviewed. Results: A total of 18 patients were enrolled in the study, the average age of the patients was 48.3 (21-82) and 10 of the cases were female and 8 of the cases were male. Among the etiologic causes of HUS in patients; the complement factor B mutation, complement factor H polymorphism, breast cancer, herbal medicine, infections and idiopathic were detected. Primer glomerulonephritis was detected in 6 cases of renal biopsy. Conclusion: Clinical and laboratory remission was obtained in 13 patients. End-stage renal failure developed in 3 of our patients.

CMV Infection in Atypical Hemolytic Uremic Syndrome

Cytomegalovirus (CMV) is a DNA virus belonging to herpesviridea family. CMV infections are seen at all age groups all through the world. Its seroprevalence is 50% in developed countries and 40- 100% in developing countries. In seropostive cases, the disease develops as result of reactivation following a treatment with immunosuppressive.Hemolytic uremic syndrome (HUS) is defined by the triad of mechanical hemolytic anemia,thrombocytopenia and renal impairment. Atypical HUS (aHUS) defines non Shigatoxin- HUSand a primary disease due to a disorder in complement alternative pathway regulation.In the present paper, a 60 years old case undergoing plasma exchange for aHUS and found to have CMV pneumonia during follow-up is presented.

C3 mesangial proliferative glomerulonephritis initially presenting with atypical hemolytic uremic syndrome: a case report

BackgroundHemolytic uremic syndrome is characterized by acute renal failure, thrombocytopenia, and Coombs-negative hemolytic anemia. In C3 mesangial proliferative glomerulonephritis, an increase in mesangial cell proliferation without thickening in the glomerular capillary wall can be seen under light microscopy, but the definitive diagnosis is made with the immunohistologic demonstration of isolated C3 deposits in the mesangium. C3 glomerulonephritis may be detected in childhood; however, in this case report we describe the first case of isolated C3 glomerulonephritis together with atypical hemolytic uremic syndrome in an adult patient.Case presentationHere we present a case of a 27-year-old white man with anuria who was hospitalized after being diagnosed as having hemolytic uremic syndrome accompanied by acute renal failure. Renal biopsy results revealed C3 glomerulonephritis. There was a complete recovery of renal function after hemodialysis, and prednisolone and plasma exchange treatment.ConclusionsC3 glomerulopathy is distinct from atypical hemolytic uremic syndrome although both diseases are due to abnormal control of the alternative complement pathway. In atypical hemolytic uremic syndrome activation of complement occurs on glomerular or microvascular endothelium causing a thrombotic microangiopathy; in most cases, no electron-dense deposits are seen on electron microscopy and glomerular C3 is not detected on immunofluorescence.

The association between therapeutic outcomes and VEGF G-1154A and C-936T gene polymorphisms in patients with glomerulonephritis.

Abstract Background: In this present study, we aimed to investigate the association between therapeutic outcomes and vascular endothelial growth factor (VEGF) G-1154A and C-936T gene polymorphisms in patients with glomerulonephritis. Methods: Thirty-eight patients with glomerulonephritis diagnosed by renal biopsy were included to the study. All patients had proteinuria at least 1 gram (g)/day in urine analysis. At the end of a yearly therapy, patients with proteinuria less than 0.5 g/day were accepted as in complete remission and they were termed as group 1. The patients with proteinuria over 0.5 g/day were accepted as in no remission and they were termed as group 2. Results: The mean age of patients in group 1 and group 2 was 35.88 ± 13.80 years and 37.30 ± 13.89 years, respectively. There were nine (50%) male and nine (50%) female patients in group 1. In group 2, seven (35%) male and 13 (65%) female patients were present. Although VEGF G-1154A (GG) gene polymorphism was found in 55% of group 2 patients, and 22.2% of group 1 patients, but the differences did not reach statistical significance. There were no statistical differences between groups in terms of other gene polymorphisms. Namely, we obtained no statistical differences between therapeutic outcomes and gene polymorphisms. Conclusions: There is a significant difference between groups in terms of VEGF G-1154A (GG) gene polymorphism, but the minority of the patient population has led to not to reach statistical significance. So, this gene polymorphism has to be investigated in larger studies.

Involvement of occipital bone in langerhans cell histiocytosis: A case report

Langerhans Cell Histiocytosis is termed as a group of diseases that leads to have same histopathology, but different clinical symptoms. The disease has 3 distinct forms and the localized form is termed as Eosinophilic granuloma . Eosinophilic granuloma is the localized form of which has the least clinical severity and the most favourable subtype in Langerhans Cell Histiocytosis group. The treatment options are available as surgery removal, chemotherapy, and radiotherapy alone or in combinations. In this paper, a young adult patient was represented who referred to our clinic with complaints of swelling and pain on right occipital region, and who diagnosed as Langerhans Cell Histiocytosis (Eosinophilic granuloma) after evaluation of radiologic tests and histopathologic survey.
