Colonic Conduit in Children

1996

Complication rates of up to 86.6% have been reported after creation of an ileal conduit. In contrast to others, we construct an antirefluxing isoperistaltic colonic for incontinent diversion in children.Between 1968 and 1989 a colonic conduit was created in 105 patients up to age 20 years for neurogenic bladder (76), bladder exstrophy (16) and other reasons (13). Long-term followup (minimum 5 years, mean 16.3 years, range 5 to 26) was possible in 84 patients (159 renal units).Early and late stenosis at the ureterocolic anastomosis, and stomal stenosis occurred in 7.6 and 15.5% of the cases, respectively. Renal calculi developed in 8.2% of the renal units. Eight kidneys without function afte…

Consensus interferon and ribavirin for patients with chronic hepatitis C and failure of previous interferon-alpha therapy.

2006

BACKGROUND The efficacy of consensus interferon (CIFN), a synthetic IFN with optimised in vitro activity, was assessed in chronic hepatitis C virus (HCV) patients who had failed the pretreatment with interferon-alpha (IFNalpha) and ribavirin. METHODS One hundred and three patients after non-response (n=69) or relapse (n=34) to IFNalpha+/-ribavirin were randomly assigned to high-dose induction (CIFN 27-->9 microg daily for 24 weeks, 9 microg t.i.w. for 24 weeks) or low-dose treatment (CIFN 18 microg t.i.w. for 12 weeks, 9 microg t.i.w. for 36 weeks); each with ribavirin 800 mg/day. Follow-up was 24 weeks. RESULTS Non-responder patients treated with high-dose induction had higher early virolo…

Histopathology of ameloblastoma of the jaws; some critical observations based on a 40 years single institution experience

2011

The aim of the present study is to examine all cases of intraosseous benign ameloblastomas treated between 1970 and 2010 in a single institution and to look for a possible correlation between the histopathological aspects and the demographical and clinical parameters, as well as the treatment outcome. The data of a total number of 44 patients were retrieved from the records. Nine patients were excluded because of doubt about the correct diagnosis (8 patients) or because of an extra-osseous presentation (1 patient). No statistically significant differences were found between the histopathological (sub)types of ameloblastomas and the demographical and clinical parameters, nor between the hist…

Improved Responses to Pegylated Interferon Alfa-2b and Ribavirin by Individualizing Treatment for 24–72 Weeks

2011

Guidelines recommend that patients with chronic hepatitis C virus (HCV) infection be treated with pegylated interferon and ribavirin for 24, 48, or 72 weeks, based on their virologic response to treatment. We investigated the effects of treating patients for individualized durations.We treated 398 treatment-naïve patients who had HCV genotype 1 infections with pegylated interferon alfa-2b and ribavirin for 24, 30, 36, 42, 48, 60, or 72 weeks (mean of 39 weeks, termed individualized therapy); the duration of therapy was determined based on baseline viral load and the time point at which HCV RNA levels became undetectable (measured at weeks 4, 6, 8, 12, 24, and 30). Results were compared with…

Prevalence and characterization of cardiac involvement in Hunter syndrome.

2011

To assess the prevalence of cardiovascular signs and symptoms in a large group of patients with Hunter syndrome, an X-linked metabolic disorder caused by a deficiency of the lysosomal enzyme iduronate-2-sulfatase.The Hunter Outcome Survey was established to characterize the natural history of Hunter syndrome and to assess the response to enzyme replacement therapy. Echocardiographic and electrocardiographic examination results were available for 102 patients who were enzyme replacement therapy-naïve in the Hunter Outcome Survey (median age at examination, approximately 8 years) as of Jan 23, 2009.The most common cardiovascular finding was valve disease, which was present in 63% of patients.…

Rapid Musculoskeletal Magnetic Resonance Imaging Using Integrated Parallel Acquisition Techniques (IPAT) - Initial Experiences

2003

Purpose To investigate the feasibility of using multiple receiver coil elements for time saving integrated parallel imaging techniques (iPAT) in traumatic musculoskeletal disorders. Material and methods 6 patients with traumatic derangements of the knee, ankle and hip underwent MR imaging at 1.5 T. For signal detection of the knee and ankle, we used a 6-channel body array coil that was placed around the joints, for hip imaging two 4-channel body array coils and two elements of the spine array coil were combined for signal detection. All patients were investigated with a standard imaging protocol that mainly consisted of different turbo spin-echo sequences (PD-, T (2)-weighted TSE with and w…

Influence of perioperative dexamethasone on delayed union in mandibular fractures: a clinical and radiological study

2014

Background: The aim was to clarify the occurrence of delayed union after surgical treatment of mandibular fracture and investigate whether an association exists between perioperative use of dexamethasone and delayed union. Material and Methods: Thirty-seven patients were included in a prospective randomized study. Of these patients, 19 (51.4%) were randomized to receive a total dose of 30 mg of dexamethasone and 18 (48.6%) served as controls. Patients underwent clinical and radiological investigation immediately, one month, three months and six months postoperatively. Radiographs were evaluated by an experienced, blinded senior oral radiologist. Results: Delayed fracture union was found in …

Uncommon oral manifestation of lichen sclerosus: critical analysis of cases reported from 1957 to 2016

2017

Background Lichen sclerosus is a mucocutaneous autoimmune disease which might be initiated by infectious pathogens as Borrelia Bugrdorferi and HPV. This disease shows destructive potential and is rarely diagnosed in oral mucosa. The purpose of this paper is to evaluate the characteristics of cases described in literature from 1957 to 2016, looking to provide valuable evidence about clinicopathologic features of this disease. Material and Methods A MedLine search was performed aiming to find oral lichen sclerosus cases in literature and discuss its demographical and pathological characteristics as well as treatment methods performed for these cases. Results 34 oral lichen sclerosus cases wit…

Course of cognitive deficits in first episode of non-affective psychosis: a 3-year follow-up study.

2013

Abstract Cognitive dysfunctions are critical determinants of the quality of life and functionality in schizophrenia. Whether the cognitive deficits present at an early stage, are static or change across one's lifespan is still under debate. This study aims to investigate the long-term (3 years) course of cognitive deficits in a large and representative cohort of first episode schizophrenia spectrum patients (N = 155),and evaluate their influence on disability. In addition, a healthy control sample (N = 43) was also studied for comparison. This study evaluates the performance of patients and controls in a battery of cognitive assessments using baseline, 1-year and 3-year follow-up designs. T…

Demographic profile of oral nonodontogenic cysts in a Brazilian population

2013

Objectives: The purpose of this study was to determine the clinical and demographic characteristics of oral non- odontogenic cysts (ONOC) in a Brazilian population over a 53-year period and to compare this data with the literature. Study D esign: A total of 20.391 biopsies records were evaluated, from April/1959 to August/2012. Cases of oral developmental cysts were selected. Data regarding age, gender, time of evolution, and anatomic site of all cases were collected. The data were analyzed by descriptive statistics. Results: Among 20.391 oral biopsies, 71 (0.35%) met the criteria of ONOC. Females accounted for 50.70% of all cases. The mean age observed was 38.14 years (range: 5-88 years). …
