Effects of the hyperbaric oxygen on de novo bone formation during periosteal distraction.

Objective: The purpose of this study was to investigate the effect of hyperbaric oxygen (HBO) therapy on de novo bone formation during periosteal distraction (PD).

Materials And Methods: Periosteal distraction was performed in 24 mature male New Zealand rabbits using a custom-designed device placed on the lateral surface of the mandibular corpus. Twelve rabbits (group H) were given adjunctive HBO treatment, whereas 12 rabbits (group N) were kept in a normal environment (normobaric oxygen).

The evaluation of the effects of hyperbaric oxygen therapy on new bone formation obtained by distraction osteogenesis in terms of consolidation periods.

Objective: The aim of this study was to evaluate the effect of hyperbaric oxygen therapy on new bone formation obtained by distraction osteogenesis in long- or short-term consolidation periods.

Materials And Methods: Twenty-four rabbits were used. The animals were divided into two groups of 12 animals each, and vertical mandibular distraction osteogenesis was performed.

Ploidy status of odontogenic tumors with epithelial components.

Objective: To evaluate the DNA ploidy status of different histologic types of odontogenic tumors (OTs) with epithelial components.

Study Design: Biopsy materials of cases that were diagnosed as ameloblastoma or OT with epithelial component were retrieved from archives. Routine hematoxylin-eosin sections were prepared from paraffin-embedded tumor materials.

No regression of renal amyloid mass despite remission of nephrotic syndrome in a patient with TRAPS following etanercept therapy.

Reactive systemic (AA) amyloidosis leading to renal failure is the most severe complication of tumor necrosis factor receptor-associated periodic syndrome (TRAPS). There is now growing evidence to suggest that anti-tumor necrosis factor (anti-TNF) agents may be an attractive treatment option for amyloidosis not only in TRAPS but in several forms of secondary amyloidosis complicating inflammatory rheumatic diseases. In most of the reported cases, anti-TNF agents were deemed successful on the basis of regression of proteinuria and either improvement or stabilization of creatinine clearance, while objective proof of renal amyloid regression either by serum amyloid P scintigraphy or biopsy is limited.

Clinical and stereologic evaluation of osteochondroma.

Osteochondroma is a benign tumor that is unusual in the maxillofacial region. Anatomy of the region, especially the mandible, is important for surgical intervention for the condylar osteochondroma. The present case report describes evaluation of condylar hyperplasia with emphasis on the advantages and disadvantages of sterolithographic solid model and stereologic techniques for preoperative surgical planning, operation time, and prognosis.

Acute renal toxicity of 2 conditioning regimens in patients undergoing autologous peripheral blood stem-cell transplantation. Total body irradiation-cyclophosphamide versus ifosfamide, carboplatin, etoposide.

Objective: To compare acute renal toxicity of 2 conditioning regimens of total body irradiation/cyclophosphamide (TBI-Cy) and Ifosfamide, Carboplatin, and Etoposide (ICE).

Methods: Between August 1996 and February 2004, patients treated with autologous peripheral stem cell transplantation in the Department of Medical and Radiation Oncology, Gulhane Military Medical School, Ankara, Turkey with 2 different conditioning regimens was comparatively analyzed for acute renal toxicity in the early post-transplant period. Forty-seven patients received ICE regimen with 12 g/m2; 1.

Hyperbaric oxygen treatment augments the efficacy of cilazapril and simvastatin regimens in an experimental nephrotic syndrome model.

Background: Oxidative stress plays a role in the mechanism of chronic kidney disease (CKD), and antioxidant regimes are regarded as promising treatment modalities. We compared the effects of cilazapril, simvastatin, and hyperbaric oxygen (HBO) treatment on proteinuria and on oxidative stress in adriamycine (ADR)-induced proteinuria.

Methods: Seventy male Sprague-Dawley rats were housed, and 60 were injected with ADR to induce nephrosis.

Minimal change nephropathy in a 7-year-old boy with Rosai-Dorfman disease.

Rosai-Dorfman (R-D) disease is a benign lympho-histiocytosis of the lymphoid system. Immune derangement due to cytokine over-expression (tumor necrosis factor (TNF), interleukin (IL)-1b and IL-6) has been considered the cause of R-D disease. We present a 7-year-old boy with R-D disease who developed minimal change nephropathy (MCN) during the progression of R-D disease.

Hyperbaric oxygen treatment augments the efficacy of a losartan regime in an experimental nephrotic syndrome model.

Background/aims: Proteinuria is associated with oxidant stress and inflammation. Hyperbaric oxygen (HBO) treatment has anti-inflammatory and anti-oxidant effects. The aim of the study was to investigate the benefits of HBO treatment on an experimental nephrotic syndrome model.

Giant cell tumor of tendon sheath simulating giant cell tumor of bone: report of a case.

A 24-year-old male patient presented with a painful eccentric lytic lesion of the proximal tibial epiphysis with a soft tissue component. Clinical and radiological assessment led to the tentative diagnosis of aggressive giant cell tumor of bone. The patient was treated with curettage, high-speed burr, and cementation after intraoperative pathology consultation.

Medulloblastoma of the cerebellopontine angle--case report.

A 21-year-old male patient presented with a rare cerebellopontine angle medulloblastoma manifesting as cerebellar and long tract involvement signs and symptoms. The clinical and radiological characteristics of the lesion were similar to extraaxial lesions of cerebellopontine angle. The histological diagnosis of the lesion was medulloblastoma.
