Implant-supported prosthetic applications upon development of children and adolescents: a pilot study in pigs

PURPOSE: The purpose of this study is the investigation of the application of implant-supported prosthetic restorations using 2 implants supporting a fixed prosthesis during the physical growth and the development period of growing pigs. MATERIALS AND METHODS: This study was carried out on 6 male farm pigs (1 as a control). The effect of the 2 screw-type endosseous implants inserted into the premolar area on the left mandibular arches of 5 farm pigs upon the jaw was investigated during a 3.5-8-month growth period using cephalometric radiographs. The cephalographs were taken with a specially standardized cephalostat, and a significant test of differences between 2 partners was used to evaluate them. RESULTS: The study suggested that the implants showed alveolar elevation by bone growth but could not keep pace with the natural teeth eruptions and the bone growth in the region. CONCLUSION: Although the sagittal and transverse developments of the neighboring bone region are greater than the implant-inserted region, the difference in this growth can be tolerated by corrections or modifications of implant-supported superstructures.     

Cor triatriatum dexter in two adult patients

Cor triatriatum dexter, in which the right atrium (RA) is divided into two chambers by a membrane, is a very rare congenital abnormality. In this abnormality, there is a high incidence of associated congenital abnormalities, particularly of the right heart. We presented two men with cor triatriatum dexter. Echocardiography is discussed as a non-invasive diagnostic tool.     

Comparison with the Pan Malaria IgG assays for malaria diagnosis and direct microscopy among suspected malaria patients in Sanliurfa

In this study, we evaluated the usage of the Pan Malaria IgG CELISA test in the diagnosis of malarial infections in Siverek-Sanliurfa, Turkey, where malarial infection is endemic and there are minimal health services available. The Pan Malaria IgG CELISA (Cellabs) test, which uses recombinant antigens and detects exposure to all four forms of malaria (P. falciparum, P. vivax, P. ovale and P. malariae) was used as individuals. Using the consensus microscopy results as the standard, sensitivity of ELISA for detection of any malarial infection in the rural populations was 83%, specificity was 85%. These results show that the performance of ELISA for the detection of any malarial infection is adequate for acute- and post-emergency situations and rural populations when the alternative is just clinical diagnosis.     

The value of tartrate resistant acid phosphatase (TRAP) immunoreactivity in diagnosis of hairy cell leukemia

Hairy cell leukemia (HCL) is a rare chronic B-cell lymphoproliferative disorder characterized by splenomegaly, pancytopenia, and circulating atypical lymphocytes with circumferential cytoplasmic projections. We investigated the specificity and the sensitivity of anti-TRAP antibody immunoreactivity in 57 cases of HCL. We found that there is a statistically highly significant difference between TRAP immunoreactivities of the study and the control groups, and HCL can be diagnosed by TRAP immunoreactivity in bone marrow trephine biopsy materials with a specificity of 98.27 % and a sensitivity of 100%.     

Contrast-enhanced CT and MRI findings of atypical hepatic Echinococcus alveolaris infestation

Diagnosis of liver infestation by Echinococcus alveolaris (EA) is based on serological and radiological findings. In this report, we present a 15-year-old girl with atypical hepatic EA infestation showing central punctate calcifications and contrast enhancement on the portal and late phases of CT and MRI. CT showed a hypodense mass involving more than half of the liver with prominent central calcifications. MRI revealed hypointense signal of the infiltrative mass on both T1- and T2-weighted images. Contrast enhancement is a unique finding in hepatic EA infestation that may cause difficulties with diagnosis. MRI may provide invaluable information in the diagnosis of EA infestation of the liver, either by disclosing the infiltrative pattern of infestation without significant effect to vascular structures, or by the signal characteristics.     

An Assessment of the Effects of Two Types of Bioresorbable Barriers to Prevent Postoperative Intra-Abdominal Adhesions in Rats

Purpose This study assessed and compared the efficacy of two types of bioresorbable membranes in the prevention of postoperative adhesion under clean contaminated and bacterial peritonitis conditions using a cecal ligation and puncture model in rats. Methods Wistar albino rats (n = 72) were divided into six groups. Bacterial peritonitis was induced using a cecal ligation and puncture model in groups 2, 4, and 6. Groups 1, 3, and 5 served as controls for clean contaminated procedures in the absence of bacterial peritonitis. Groups 1 and 2 were the untreated clean contaminated and bacterial peritonitis groups and served as controls for the effect of the bioresorbable membranes in each condition. In groups 3 and 4, a 1.5 × 3 cm USP glycerol/sodium hyaluronate/carboxymethylcellulose membrane was wrapped around the cecal resection area and a 2 × 4 cm membrane was left under the incision. The oxidized regenerated cellulose membrane was similarly applied in groups 5 and 6. Four weeks later, the adhesions were evaluated. In addition, fibrosis and inflammation were observed histopathologically. Results Adhesion development (P = .008), fibrosis (P = .008), and inflammation (P = .0001) differed among the groups. Both materials increased adhesion formation in the bacterial peritonitis condition. Increased fibrotic activity was detected in all material-applied groups under both conditions. In addition, more inflammation was detected in the groups that received the application of a material, especially in the presence of bacterial peritonitis. Conclusion Neither material prevented adhesions in clean contaminated conditions. Moreover, they increased adhesion formation in bacterial peritonitis.
