Clinical and epidemiological aspects of respiratory syncytial virus lower respiratory tract infections

This paper has analyzed respiratory syncytial virus lower respiratory tract infections in 201 hospitalized children. In children with wheezing, erythrocyte sedimentation rate (ESR) was significantly higher in those with pneumonia than with syndroma pertussis, while the white blood cell (WBC) count was significantly lower in patients with bronchitis than in those with bronchiolitis and syndroma pertussis. Bronchodilatators were applied in 75.6% and corticosteroids in 20% of patients. Ten patients were ventilated. Fatal disease outcome was observed in one infant. Twelve consecutive-year study of respiratory syncytial virus (RSV) infections showed that 27.3% of these diseases were bronchiolitis and pneumonia.

Thermography‐measured effect of capsaicin,methylprednisolone and mitomycin on the survival of random skin flaps in rats

Aims: This study was designed to determine if steroids, capsaicin and mytomicin improved skin flap survival in rats, and it has confirmed that thermography is an effective method to measured skin flap vitality. Methods: Forty female Wistar rats were randomised into four groups. A standardised full thickness inferiorly based dorsal random‐pattern skin flap was raised, and a gelatine sponge was placed before suturing between the flap and its recipient bed, soaked with 0.9 % saline in the control group and with capsaicin, methylprednisolone and mitomycini in the experimental groups. Vitality of the flap and of the survival area was measured by infrared thermography. Results: Methylprednisolone statistically significant decrease skin flap necrosis, approximately 56%, when compared with controls (P< 0.05). Conclusion: Corticosteroids applied subcutaneously in a single dose on a gelatine sponge produced a statistically significant improvement of the survival of random skin flaps in rats, whereas capsaicin and mitomycin showed no improvement.     

Superoxide dismutases in chronic gastritis

Human gastric diseases have shown significant changes in the activity and expression of superoxide dismutase (SOD) isoforms. The aim of this study was to detect Mn‐SOD activity and expression in the tissue of gastric mucosa, primarily in chronic gastritis (immunohistochemical Helicobacter pylori‐negative gastritis, without other pathohistological changes) and to evaluate their possible connection with pathohistological diagnosis. We examined 51 consecutive outpatients undergoing endoscopy for upper gastrointestinal symptoms. Patients were classified based on their histopathological examinations and divided into three groups: 51 patients (archive samples between 2004–2009) with chronic immunohistochemical Helicobacter pylori‐negative gastritis (mononuclear cells infiltration were graded as absent, moderate, severe) divided into three groups. Severity of gastritis was graded according to the updated Sydney system. Gastric tissue samples were used to determine the expression of Mn‐SOD with anti‐Mn‐SOD Ab immunohistochemically. The Mn‐SOD expression was more frequently present in specimens with severe and moderate inflammation of gastric mucosa than in those with normal mucosa. In patients with normal histological finding, positive immunoreactivity of Mn‐SOD was not found. Our results determine the changes in Mn‐SOD expression occurring in the normal gastric mucosa that had undergone changes in the intensity of chronic inflammatory infiltrates in the lamina propria.     

Percutaneous embolization of idiopathic renal arteriovenous fistula using Amplatzer vascular plug II

Renal arteriovenous fistula (AVF) presents a rare but important condition that can be acquired, congenital, or idiopathic. Embolization techniques have recently been considered the first-line therapy in the treatment of these lesions, but they carry a possible high risk of distal migration of embolic agents into the venous and pulmonary circulation. This risk is especially important with large, high-flow fistulas. In this report, we present a case in which a 31-year-old man with a symptomatic idiopathic AVF was treated with embolization using the Amplatzer vascular plug II after unsuccessful superselective embolization using coils. This method allowed for complete occlusion of the high-flow fistula with good preservation of arterial supply to the renal parenchyma.     

Alveolar Bone Grafting in Cleft Patients from Bone Defect to Dental Implants

Cleft lip and palate is the most common congenital deformity affecting craniofacial structures. Orofacial clefts have great impact on the quality of life which includes aesthetics, function, psychological impact, dental development and facial growth. Incomplete fusion of facial prominences during the fourth to tenth week of gestation is the main cause. Cleft gaps are closed with alveolar bone grafts in surgical procedure called osteoplasty. Autogenic bone is taken from the iliac crest as the gold standard. The time of grafting can be divided into two stages: primary and secondary. The alveolar defect is usually reconstructured between 7 and 11 years and is often related to the development of the maxillary canine root. After successful osteoplasty, cleft defect is closed but there is still a lack of tooth. The space closure with orthodontic treatment has 50-75% success. If the orthodontic treatment is not possible, in order to replace the missing tooth there are three possibilities: adhesive bridgework, tooth transplantation and implants. Dental implant has the role of holding dental prosthesis, prevents pronounced bone atrophy and loads the augmentation material in the cleft area. Despite the fact that autologous bone from iliac crest is the gold standard, it is not a perfect source for reconstruction of the alveolar cleft. Bone morphogenic protein (BMP) is appropriate as an alternative graft material. The purpose of this review is to explain morphology of cleft defects, historical perspective, surgical techniques and possibilities of implant and prosthodontic rehabilitation.Key words: Cleft Lip, Cleft Palate, Alveolar bone grafting, Bone Morphogenic Proteins, Dental implants, Dental prosthesis, Orthodontic Space Closure
