The rare coexistence of high titer inhibitor development and gastrointestinal stromal tumor in a patient with severe hemophilia: A case report

Hemophilia is a hereditary disease with impaired blood coagulation due to a genetic deficiency of blood coagulation factors. The development of inhibitors further complicates the course of the disease and management. The case is here reported of a haemophilia patient who presented with coexisting development of high titer inhibitor with Gastrointestinal Stromal Tumor (GIST) diagnosis and was admitted with upper gastrointestinal system bleeding. The patient had no prior history of inhibitor presence. During all procedures including surgery, excellent hemostasis was achieved with rFVIIa treatment and no hemorrhagic complication was observed. To the best of our knowledge, this constitutes the first reported case of GIST associated with inhibitor development in a hemophilia A patient.     

Right Ventricular Hypertrophy and Dilation in Patients With Human Immunodeficiency Virus in the Absence of Clinical or Echocardiographic Pulmonary Hypertension

Background

Involvement of right-sided heart chambers (RSHCs) in patients infected with human immunodeficiency virus (HIV) is common and is usually attributed to pulmonary arterial or venous hypertension (PH). However, myocardial involvement in patients with HIV is also common and might affect RSHCs even in the absence of overt PH. Our aim was to define morphologic and functional alterations in RSHC in patients with HIV and without PH.

A Comparison of Demographic and Clinical Characteristics of Syrian and Turkish Patients with Cutaneous Leishmaniasis

Cutaneous leishmaniasis (CL) is a significant public health problem with increasing incidence, especially in extreme circumstances. In this study, we compared the sociodemographic and clinical characteristics of 685 Syrian CL patients afflicted by the Syrian conflict and 685 Turkish CL patients in 2012. Patient age, gender, duration of disease, lesion size, type, and localization were evaluated. The duration of CL disease in Syrian CL patients (4.5 ± 4.3 weeks) was shorter than that of Turkish CL patients (11.9 ± 9.7 weeks). The number of lesions was greater in Syrian patients (2.46 ± 2.43) than in Turkish patients (1.93 ± 1.47). Lesion sizes were comparable between both groups (Syrian, 11.2 ± 8.7 mm; Turkish, 10.7 ± 7.7 mm). In Syrian CL patients, nodular type lesions were the most common (325 patients, 49.1%), whereas, in Turkish CL patients, ulcer type lesions were the most common (352 patients, 51.5%). Our results indicate variations in the clinicoepidemiological features of CL between Turkish and Syrian patients within Sanliurfa province. This highlights the impact of social unrest and environmental conditions on the epidemiology of CL within this region. Approaches to prevention, control, and treatment of CL in these areas should take into consideration the emerging changes in clinicoepidemiological parameters of the disease.     

The effect of the application of gaseous ozone and ND:YAG laser on glass‐fibre post bond strength

The aim of this study was to investigate the effects of the application of gaseous ozone and Nd:YAG laser on glass‐fibre post bond strength. Forty‐two madibular premolar roots were cut, endodontically instrumented and irrigated with 2.5% NaOCl. Post spaces were prepared and roots were divided into three groups (n = 14). The antimicrobial pretreatment was conducted as follows: gaseous ozone, Nd:YAG laser and control (no additional disinfection methods). Scanning electron microscope analysis was made for each group (n = 2). A resin cement was used for luting the posts. For push‐out test, each root was cut horizontally (two cervical, two middle and two apical). Statistical analyses were performed with one‐way anova (α = 0.05). Fracture types were observed. There was no statistically significant difference between the groups (P > 0.05). There were statistically significant differences in cervical and apical segments of laser and control groups (P < 0.05). The disinfection of the post spaces with Nd:YAG laser and ozone had no adverse effects on bond strength of glass‐fibre post.     

Vancomycin-resistant enterococci colonization in a neonatal intensive care unit: who will be infected?

Objective: To determine the incidence of vancomycin-resistant enterococcus (VRE) colonization in our neonatal intensive care unit (NICU) over five-year period, rate of progression to VRE infection and associated risk factors.

Methods: A retrospective analysis of a prospective surveillance for VRE colonization and health care-associated infections was made. Contact precautions were taken against colonization, although the application varied over the years due to repairs in the unit.

Results: VRE rectal colonization was detected in 200/1671 neonates (12%) admitted to NICU. It showed great interannual variability from 1.9% to 30.3%. Sytemic VRE infection developed in 6/200 VRE-colonized patients (3%) within a median of 9 days (range: 3–58 days). The risk factors for VRE infection development identified in the univariate analysis were long hospital stay (≥30 days), necrotizing enterocolitis, surgical procedure, extraventricular drainage, receipt of amphotericin B and receipt of glycopeptides after detection of VRE colonization. Crude in-hospital mortality was higher in neonates who developed a systemic VRE infection (p?<?0.001).

Conclusion: Maintaining physical conditions in the unit favorable for infection control and rational use of antibiotics are essential in the control of VRE colonization and resultant infections. Special attention should be directed to VRE-colonized babies carrying the risk factors.
