The Relationship Between Money Supply, Interest Rate and Inflation Rate: an Endogeneity-Exogeneity Approach

After the 2008 Financial Crisis, The Central Bank is Turkey as well as many countries, has implemented a policy of increasing the money supply. It is a known fact that the changes in the money supply are considerable extent determinative in interest rate and inflation rate such as orientations of macro economics variables. The purpose of this study is to investigate the relationship between money supply, interest rate and inflation rate in Turkey after the 2008 Financial Crisis. In accordance with this purpose, 2008:1- 2015:12 period money supply, interest rate and inflation rate monthly data are used. Commonly in applied studies, the relationship between these variables is analysed with Cholesky Decomposition Method of Variance based Vector Autoregression Model (VAR). But this method is affected by ordering of the variables according to endogeneity-exogeneity approach, when ordering of the variables were changed, the results are changed and therefore policy proposals are changed. In analysis of the study, both Cholesky and Pesaran and Shin’s proposal method is used. According to Cholesky Variance Decomposition result at the end of the a month, when all changes in inflation is explained by inflation, this rate is 85% according to Generalized Decomposition Method of Variance result

Evaluation of the Clinical and Sociodemographic Features of Turkish Patients with Vitiligo

Vitiligo is an acquired, pigmentary skin disorder that affects about 0.1-4.0% of the population. In this study, we aimed to investigate the disease features such as age of onset, disease duration, clinical and sociodemographic characteristics, and laboratory parameters of patients with vitiligo. A hundred patients who were in follow-up for vitiligo between the period of June 2013 and May 2014 were included in the study. The clinical features and laboratory parameters were retrospectively obtained from the records of the patients. The mean age was 34.9±16.8 years. The most common clinical types were focal and acrofacial. Facial involvement was the most common localization. Forty-five (45%) patients had an associated systemic disease. Autoimmune thyroid disease, essential hypertension, and alopecia  areata, which were observed in 28%, 8%, and 5% of patients, respectively, were the most common associated diseases. Twenty-one percent of the patients had low ferritin levels, 20% had low iron levels, 12% had low vitamin B12 levels, and 1% had low folic acid levels. The prevalence of anti-TG (anti-thyroglobulin) and anti-TPO (anti-thyroid peroxidase) antibodies were found 17% and 27% of the patients, respectively. We found that the clinical characteristics of vitiligo in our patients were similar to those in other studies. We observed laboratory abnormalities and accompanying diseases associated with vitiligo. Therefore we conclude that laboratory examinations including thyroid antibodies and regular follow-up of these patients are essential.</div

Epidemiology of pemphigus in Turkey: One-year prospective study of 220 cases

Pemphigus is a group of rare and life-threatening autoimmune blistering diseases of the skin and mucous membranes. Although they occur worldwide, their incidence shows wide geographical variation, and prospective data on the epidemiology of pemphigus are very limited. Objective of this work is to evaluate the incidence and epidemiological and clinical features of patients with pemphigus in Turkey. All patients newly diagnosed with pemphigus between June 2013 and June 2014 were prospectively enrolled in 33 dermatology departments in 20 different provinces from all seven regions of Turkey. Disease parameters including demography and clinical findings were recorded. A total of 220 patients were diagnosed with pemphigus during the 1-year period, with an annual incidence of 4.7 per million people in Turkey. Patients were predominantly women, with a male to female ratio of 1:1.41. The mean age at onset was 48.9 years. Pemphigus vulgaris (PV) was the commonest clinical subtype (n=192; 87.3%), followed by pemphigus foliaceus (n=21; 9.6%). The most common clinical subtype of PV was the mucocutaneous type (n=83; 43.2%). The mean Pemphigus Disease Area Index was 28.14±22.21 (mean ± Standard Deviation).  The incidence rate of pemphigus in Turkey is similar to the countries of South-East Europe, higher than those reported for the Central and Northern European countries and lower than the countries around the Mediterranean Sea and Iran. Pemphigus is more frequent in middle-aged people and is more common in women. The most frequent subtype was PV, with a 9-fold higher incidence than pemphigus foliaceus.   </p

Hematopoietic Cell Transplantation Cures Adenosine Deaminase 2 Deficiency : Report on 30 Patients

Correction; Early Access: ' DOI: 10.1007/s10875-022-01280-y Early Access: APR 2022Purpose Deficiency of adenosine deaminase 2 (DADA2) is an inherited inborn error of immunity, characterized by autoinflammation (recurrent fever), vasculopathy (livedo racemosa, polyarteritis nodosa, lacunar ischemic strokes, and intracranial hemorrhages), immunodeficiency, lymphoproliferation, immune cytopenias, and bone marrow failure (BMF). Tumor necrosis factor (TNF-alpha) blockade is the treatment of choice for the vasculopathy, but often fails to reverse refractory cytopenia. We aimed to study the outcome of hematopoietic cell transplantation (HCT) in patients with DADA2. Methods We conducted a retrospective study on the outcome of HCT in patients with DADA2. The primary outcome was overall survival (OS). Results Thirty DADA2 patients from 12 countries received a total of 38 HCTs. The indications for HCT were BMF, immune cytopenia, malignancy, or immunodeficiency. Median age at HCT was 9 years (range: 2-28 years). The conditioning regimens for the final transplants were myeloablative (n = 20), reduced intensity (n = 8), or non-myeloablative (n = 2). Donors were HLA-matched related (n = 4), HLA-matched unrelated (n = 16), HLA-haploidentical (n = 2), or HLA-mismatched unrelated (n = 8). After a median follow-up of 2 years (range: 0.5-16 years), 2-year OS was 97%, and 2-year GvHD-free relapse-free survival was 73%. The hematological and immunological phenotypes resolved, and there were no new vascular events. Plasma ADA2 enzyme activity normalized in 16/17 patients tested. Six patients required more than one HCT. Conclusion HCT was an effective treatment for DADA2, successfully reversing the refractory cytopenia, as well as the vasculopathy and immunodeficiency. Clinical Implications HCT is a definitive cure for DADA2 with > 95% survival.Peer reviewe

Approximation by Bernstein-Chlodowsky operators of max-product kind

We define max-product (nonlinear) Bernstein-Chlodowsky operators and obtain some upper estimates of approximation error for some subclasses of functions. We also investigate the shape-preserving properties for these operators

Soft tissue chondroma of the index finger: Clinical, histological and radiological findings in a unique case

A chondroma is a benign, slow-growing cartilaginous tumor. When arising in the medullary cavity of a bone it is referred to as an enchondroma-a very common bone tumor. When occurring in soft tissue without any connection to bone, which is extremely rare, it is known as a soft-tissue chondroma (STC). A 38-year-old female presented with a 2- year history of right index finger pulp swelling in the absence of trauma. On physical examination a firm, immobile nodule, approximately 1 cm in diameter, was observed on the palmar side of the right index finger. The overlying skin was normal. Plain X-ray showed a dense, soft tissue shadow without calcification in the right index finger pulp, but the adjacent bones were intact. MRI showed a 1-cm diameter, well-demarcated lesion with intermediate signal intensity on T1-weighted images and high signal intensity on T2-weighted images. MRI also showed that the tumor had no bony involvement and that the adjacent bones were normal. Histopathological examination of the biopsy specimen showed lobules of mature hyaline cartilage with chondrocytes in the lacunae in the dermal and subdermal layers. Mitotic figures and an increase in cellular atypism were not observed. Based on the histopathological and radiological findings, the mass was thought to be an STC and total excision was performed. Examination of the excised mass confirmed the diagnosis of STC. STC should be considered in patients with a slowly growing, mildly painful cutaneous mass
