A thoracic-epidural granulocytic sarcoma case that was diagnosed preceding the onset of and that recurred co-incidental to acute promyelocytic leukemia, which developed after surgical treatment.

Granulocytic sarcoma or chloroma is a tumor seen in myelocytic leukemia. Spinal epidural onset is rare and is generally seen before or together with the onset of myelocytic leukemia. An epidural mass located at the 2nd-5th thoracic levels in an 18-year-old male patient was pathologically diagnosed as granulocytic sarcoma. Radiotherapy was performed after surgical intervention. Ten months later, he was re-admitted with abdominal pain. At this time, an epidural mass at the 6th-9th thoracic levels was detected on magnetic resonance imaging, and acute promyelocytic leukemia was diagnosed. After systemic chemotherapy, partial remission was achieved. We aimed to present this rare case with its remarkable follow-up findings.</p

The effects of peritoneal dialysis and hemodialysis on serum tumor necrosis factor-alpha, interleukin-6, interleukin-10 and C-reactive-protein levels.

BACKGROUND: Markers of an acute phase reaction, such as C-reactive protein (CRP) or tumor necrosis factor-alpha (TNF-alpha) and interleukin (IL)-6, are predictive for cardiovascular morbidity and mortality in normal subjects and in chronic renal failure patients. In this study, we aimed to investigate serum TNF-alpha, IL-6, IL-10 and CRP levels in continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis (HD) patients. MATERIALS AND METHODS: Serum levels of TNF-alpha, IL-6, IL-10 and CRP levels were measured in 30 patients who were just diagnosed with end-stage renal failure and treated, with 16 CAPD (nine female, seven male) and 14 HD (eight female, six male) patients, before CAPD or HD treatment and after 3 months from the beginning of CAPD or HD in patients with no clinical signs of infection. The control groups were 20 healthy persons of similar age and sex. Serum levels of TNF-alpha, IL-6, IL-10 and CRP were measured by enzyme-linked immunosorbent assay in stable CAPD and HD patients and in healthy persons. RESULTS: The mean serum levels of TNF-alpha, IL-6, IL-10 and CRP showed no significant differences between the CAPD and HD patients for the beginning values and the third month of treatment. However, serum TNF-alpha, IL-6, IL-10 and CRP levels were higher than the control group in the CAPD and HD patients regarding the beginning values and the third month of treatment (p < 0.001). CONCLUSIONS: CAPD and HD of the renal replacement therapy have no effects on serum CRP and cytokines

Obstrüktif uyku apneli ve horlayan erişkin erkek hastaların dentofasiyal özelliklerinin değerlendirilmesi

Amaç: Bu çalışmanın amacı obstrüktif uyku apne sendromu (OUAS) olan erişkin erkek hastaların kraniofasiyal morfolojik özellikleri değerlendirmektir. Gereç ve Yöntem: Çalışmada 80 erkek hastanın (60 sefalogramları değerlendirildi. Bireyler Grup 1: horlama (AHİ5); Grup 2: hafif OUAS (5AHİ15); Grup 3: orta OUAS(15 AHİ30) ; Grup 4: şiddetli OUAS (AHİ30) olarak değerlendirildi. Sefalogramlar üzerinde hyoid, dil kökü ve yumuşak damak konumu, kranioservikal postür ve havayolu genişliğini belirleyen ölçümler yapıldı. Gruplar arasındaki farklar normal dağılım gösteren değişkenlerde tek yönlü varyans analizi ve Duncan testiyle, normal dağılım göstermeyen değişkenlerde Kruskal düzeltmesi uygulanarak Mann Whitney U testiyle yapıld

Effects of cavity disinfectants on bond strength of an etch-and-rinse adhesive to water- or ethanol-saturated sound and caries-affected dentin

Objective: To evaluate the effect of cavity disinfectants on the immediate microtensile bond strength (TBS) of an etch-and-rinse adhesive to water- and ethanol-saturated sound and caries-affected dentin (CAD). Material and Methods: Thirty-six human molars were sectioned to expose 1/3 of the mid-coronal dentin surface. Sound (n=18) and CAD (n=18) specimens were divided into six groups each (n=3): one positive control (sound), one negative control (CAD), and five experimental groups each. In the control group, dentin surfaces were bonded using an etch-and-rinse adhesive with a traditional water-wet bonding technique. In the experimental groups, ozone was applied before etching and chlorhexidine after etching. In the ethanol-wet bonding groups, acid-etched dentin surfaces were treated with ethanol. Following adhesive application and composite buildups, bonded specimens were sectioned to form sticks. Failure modes were analyzed using a stereomicroscope. Results: The water-wet bonded sound control group yielded the highest TBS among all groups (p0.05). Conclusions: The TBS values of CAD were lower than those of sound dentin. Ethanol-wet bonding improved the TBS of CAD. Ozone application reduced the TBS in both sound and CAD; chlorhexidine improved the immediate TBS after etching in CAD

TAP-Stenting Technique for Bifurcation Stenosis of Celiac Artery

We report a clinical course of a patient who developed severe ischemic liver injury and total occlusion of the celiac artery (CA). A 40-year-old man presented with abdominal pain. Computed tomography indicated total occlusion of the CA. Laboratory data demonstrated markedly elevated hepatic enzymes. An exploratory laparotomy was not necessitated due to absence of peritonism. The patient was successfully treated by endovascular recanalization of the CA occlusion via transcatheter balloon angioplasty and TAP-stenting (T-stenting and small protrusion) technique. Endovascular intervention in patients solely with liver failure appears practicable and early treatment is advised

The efficacy of three desensitizing agents used to treat dentin hypersensitivity

Background. In a single-center, double-masked, split-mouth-designed, clinical short-term trial, the authors assessed the clinical responses of teeth with dentin hypersensitivity (DH) after treating the teeth with one of three desensitizing agents across four weeks
