Costochondral graft with green-stick fracture used in reconstruction of the mandibular condyle : experience in 13 clinical cases
2008
Since its publication in 1920 by Gillies, costochondral grafts have been used by surgeons to replace an injured mandibular condyle and to reconstruct the temporomandibular joint. This procedure is currently applied in cases of congenital dysplasia, developmental defects, temporomandibular ankylosis, neoplastic disease, osteoarthritis and post-traumatic dysfunction. Over the years, various procedures for the reconstruction with this type of graft have been described. In 1989, Mosby and Hiatt described a technique for setting the graft securely, reducing the space between the graft and the mandibular area. In 1998, Monje and Martín-Granizo developed a variation of this method, enabling a prec…
Studies on serum groups in the Kumaon region, India
1970
A total of 469 individuals belonging to 4 endogamous groups (Brahamins, Rajputs, Doms and Tharus) from the Kumaon region (North India) were tested for Hp, Gc, Gm and Inv systems.
Histological and fine structural features of pancreatic ductal adenocarcinomas in relation to growth and prognosis: studies in xenografted tumours an…
1985
Histology and fine structure of pancreatic ductal adenocarcinomas were assessed with respect to their significance for tumour growth and prognosis. The histological parameters included glandular differentiation, nuclear anaplasia, nuclear size, and mitotic activity (number of mitoses per high power field). Using these criteria three grades of malignancy were distinguished. They correlated well with the growth kinetics of seven human pancreatic ductal adenocarcinomas transplanted into nude mice. The tumour doubling time of a G 3 carcinoma was about half that of a G 1 carcinoma. On electron microscopy the tumour grade was reflected in the degree of functional differentiation of the neoplastic…
Serum prolactin and tumors of the prostate: unchanged basal levels and lack of correlation to serum testosterone
1980
To investigate the possible role of circulatory levels of prolactin on the development of prostatic tumors, and to gain insight into the prolactin-androgen relationship, serum prolactin and testosterone were determined in 73 patients with newly diagnosed prostatic adenocarcinoma. Controls consisted of 32 patients with benign prostatic hyperplasia before treatment, 19 age-matched controls, and 21 young individuals. Hormones were measured under standardized conditions by highly specific and sensitive radioimmunoassays. There was no difference in prolactin in the elderly men regardless of prostate pathology, but a significant increment was found in young controls. Individual prolactin values d…
Manifestation and ultrastructural typing of amyloid deposits in the heart
1983
Using light and electron microscopy, 65 cases of amyloid deposits in the heart were examined. Five different groups were distinguished: I. isolated atrial amyloidosis, II. senile cardiac amyloidosis, III. cardiac amyloid accompanying chronic infections and tumors, IV. cardiac amyloid accompanying plasma cell dyscrasia, V. idiopathic cardiac amyloidosis. Seen structurally, no principal differences in the precise localization of the amyloid deposits were found in any of the groups investigated. Amyloid is always deposited in the vicinity of cells with myocytic cell differentiation (i.e. the heart muscle cells, non-striated muscle cells of the vessels), whereby the relevant basement membranes …
Treatment of epistaxis in hereditary hemorrhagic telangiectasia with tranexamic acid - a double-blind placebo-controlled cross-over phase IIIB study.
2014
Abstract Introduction Epistaxis is the most frequent manifestation in hereditary hemorrhagic telangiectasia, in which no optimal treatment exists. It can lead to severe anemia and reduced quality of life. Positive effects of tranexamic acid, an antifibrinolytic drug, have been reported on epistaxis related to this disorder. We sought to evaluate the efficacy of treating nosebleeds in hereditary hemorrhagic telangiectasia with tranexamic acid. Materials and Methods In a randomized, double-blind, placebo controlled, cross-over phase IIIB study, 1 gram of tranexamic acid or placebo was given orally 3 times daily for 3 months for a total of 6 months. Results 22 patients were included in the int…
Perceived Racial/Ethnic Discrimination and Psychological Outcomes Among Adult International Adoptees in Finland: Moderating Effects of Social Support…
2015
Quantitative literature on international adoptees and racial/ethnic discrimination is lacking despite results in qualitative studies from Europe and the United States that have consistently indicated how racism constantly complicates adoptees' everyday lives. To advance the literature, the present study examined the prevalence of perceived racial/ethnic discrimination among 213 adult international adoptees in Finland (59.6% women and 40.4% men, mean age 24.1 years), and the association between perceived racial/ethnic discrimination and psychological well-being indicators, including psychological distress and sleeping problems. In addition, we examined social support and sense of coherence a…
Absence of cardiovascular autonomic dysfunction and vagal pancreatic impairment in idiopathic achalasia of the oesophagus
2007
Abstract Extra-oesophageal autonomic dysfunction in idiopathic achalasia is not well documented, due to contradictory results reported. We aimed to study the cardiovascular and pancreatic autonomic function in patients with idiopathic achalasia. Thirty patients with idiopathic achalasia (16M/14F; 34.5 ± 10.8 years) and 30 healthy volunteers (13M/17F; 34.8 ± 10.7 years) were prospectively studied. Age >60 years and conditions affecting results of autonomic evaluation were excluded. Both groups underwent the sham feeding test and plasmatic levels of pancreatic polypeptide (PP) were determined by radioimmunoassay (basal, at 5, 10, 20 and 30 min). Cardiovascular parasympathetic (deep breathing…
Real-time ultrasound of normal adrenal glands and small tumors.
1984
The adrenals were studied prospectively with real-time ultrasound in a series of 60 healthy individuals and 13 patients with small adrenal masses sized 8-20 mm in diameter. In only one of the 60 healthy subjects was a normal adrenal gland delineated as a distinct hypoechoic structure. In all other instances only the highly echogenic suprarenal fat could be displayed. Visualization of small tumors was successful in 12 of 13 patients. The suprarenal area and small lesions were best demonstrated by a lateral intercostal approach using longitudinal and transverse scanning planes. The best access was through the 9th/10th intercostal space at the junction with the anterior and middle axillary lin…
Oral cancer: A multicenter study
2017
Background To determine the prevalence and clinicopathologic features of the oral cancer patients. Material and Methods Biopsy records of the participating institutions were reviewed for oral cancer cases diagnosed from 2005 to 2014. Demographic data and site of the lesions were collected. Sites of the lesion were subdivided into lip, tongue, floor of the mouth, gingiva, alveolar mucosa, palate, buccal/labial mucosa, maxilla and mandible. Oral cancer was subdivided into 7 categories: epithelial tumors, salivary gland tumors, hematologic tumors, bone tumors, mesenchymal tumors, odontogenic tumors, and others. Data were analyzed by descriptive statistics using SPSS software version 17.0. Resu…
