The INTERPHONE study: design, epidemiological methods, and description of the study population

2007

The very rapid worldwide increase in mobile phone use in the last decade has generated considerable interest in the possible health effects of exposure to radio frequency (RF) fields. A multinational case-control study, INTERPHONE, was set-up to investigate whether mobile phone use increases the risk of cancer and, more specifically, whether the RF fields emitted by mobile phones are carcinogenic. The study focused on tumours arising in the tissues most exposed to RF fields from mobile phones: glioma, meningioma, acoustic neurinoma and parotid gland tumours. In addition to a detailed history of mobile phone use, information was collected on a number of known and potential risk factors for t…

Analysis of thiamine transporter genes in sporadic beriberi

2014

Abstract Objective Thiamine or vitamin B 1 deficiency diminishes thiamine-dependent enzymatic activity, alters mitochondrial function, impairs oxidative metabolism, and causes selective neuronal death. We analyzed for the first time, the role of all known mutations within three specific thiamine carrier genes, SLC19 A2, SLC19 A3 , and SLC25 A19 , in a patient with atrophic beriberi, a multiorgan nutritional disease caused by thiamine deficiency. Methods A 44-year-old male alcoholic patient from Morocco developed massive bilateral leg edema, a subacute sensorimotor neuropathy, and incontinence. Despite normal vitamin B 1 serum levels, his clinical picture was rapidly reverted by high-dose in…

Methods: A 44-year-old male alcoholic patient from Morocco developed massive bilateral leg edema a subacute sensorimotor neuropathy and incontinence. Despite normal vitamin B1 serum levels his clinical picture was rapidly reverted by high-dose intramuscular thiamine treatment suggesting a possible genetic resistance. We used polymerase chain reaction followed by amplicon sequencing to study all the known thiamine-related gene mutations identified within the Human Gene Mutation Database. Results: Thirty-seven mutations were tested: 29 in SLC19 A2 6 in SLC19 A3 and 2 in SLC25 A19. Mutational analyses showed a wild-type genotype for all sequences investigated. Conclusion: This is the first genetic study in beriberi disease. We did not detect any known mutation in any of the three genes in a sporadic dry beriberi patient. We cannot exclude a role for other known or unknown mutations in the same genes or in other thiamine-associated genes in the occurrence of this nutritional neuropathy.HumansThiamineGenePolymerase chain reactionGeneticsMutationNutrition and DieteticsbiologyMembrane Transport ProteinsThiamine Deficiencymedicine.diseaseAlcoholismEndocrinologyMutationbiology.proteinThiamineMutations

Comparative effect of tacrolimus 0.1% ointment and clobetasol 0.05% ointment in patients with oral lichen planus.

2008

Background Oral lichen planus (OLP) is considered to be an autoimmune disease of unknown aetiology that affects the mucosae, especially the oral cavity. Objective We compared tacrolimus 0.1% ointment and clobetasol 0.05% ointment for the treatment of OLP. Patients and methods A total of 32 patients (20 females and 12 males; all white, Italian origin, mean age of 43.6+/-18.4 years; 16 patients per treatment group) were treated with tacrolimus or clobetasol ointment for 4 weeks in a randomized, double-blind, clinical trial. Pain severity, burning sensation, and mucosal lesion extension were assessed using a four-point scale. Results At the end of the treatment period, symptom scores were sign…

Fatal and non-fatal injuries caused by crossbows

2002

Today in modern times, traumatic injuries caused by crossbows are a rarity. The largest collection of cases so far is presented in this study, consisting of four fatalities (two homicides and two suicides) and two non-fatal injuries (grievous bodily harm and an accident). All the victims were male having an age between 31 and 54. The weapons, which were used, were mainly high-performance precision crossbows with telescopic sights and hunting bolts. The parts of the body involved were the facial/head area in three of the cases and the thorax in three of them. There were either deep or total penetration injuries to the cranium and thorax with the bolt remaining in the wound in four out of six…

Progression of untreated mild thoracic Scheuermann's kyphosis – Radiographic and functional assessment after mean follow-up of 46 years

2017

There is no data available on the radiographic development of the Scheuermann's deformity. Our purpose was to investigate radiographic deformity progression and the relation between kyphosis progression and clinical outcome in patients with untreated Scheuermann's kyphosis.Thoracic kyphosis (Th4-Th12) was measured from standing lateral radiographs in 19 patients at baseline and after mean 46-year follow-up. Mean age at baseline was 19.2 and at follow-up 64.7 years. At follow-up, height, weight, hand grip strength, and hamstring tightness were measured, and sit-to-stand and walking tests were performed. Additionally general health and quality of life questionnaires were administered.The mean…

Conservative surgery of renal cell carcinoma.

1986

Abstract From 1967 to 1985 conservative surgery (enucleation, n = 49; partial resection, n = 7) was performed for renal tumors in 57 patients (age 31-77, mean 54.8 years). Imperative indications for conservative surgery (n = 29) were chronic renal failure, benign pathology of contralateral kidney, functional or anatomical solitary kidney, and bilateral tumors. Elective conservative surgery (n = 28) was done for small, peripherally located lesions, in cases of uncertain malignancy and in one tumor detected by chance during stone surgery. Tumors removed for imperative indications were 2-11 cm (mean 5.8 cm) in size. In the elective group, tumor size ranged from 1 to 7 cm (mean 3.3 cm). Follow-…

Cancer-specific survival after radical cystectomy and standardized extended lymphadenectomy for node-positive bladder cancer: prediction by lymph nod…

2009

OBJECTIVE To investigate the associations between different overall or topographically restricted lymph node (LN) variables and cancer-specific survival (CSS) after radical cystectomy (RC) and extended LN dissection (LND) with curative intent in patients with LN-positive bladder cancer. PATIENTS AND METHODS Between 2001 and 2006, 152 patients had RC with standardized extended LND for bladder cancer with curative intent. Patients with positive LNs were stratified according to the median of the LN variables (LNs removed, number of positive LNs, LN density). CSS was related to overall and topographically restricted LN variables, e.g. different levels of LND, and relationships were tested by un…

Liver assessment and biopsy in patients with marked coagulopathy: value of mini-laparoscopy and control of bleeding.

2003

Evaluation of liver disease in patients with a high risk of postbiopsy bleeding presents a diagnostic challenge. Mini-laparoscopy offers the possibility of coagulation of biopsy site and the additional advantage of macroscopic liver assessment. We wished to assess the value and safety of mini-laparoscopy with guided biopsy as a diagnostic approach in patients in whom percutaneous liver biopsy is considered contraindicated because of a marked coagulopathy.We investigated 61 consecutive patients with marked coagulopathy (prolonged international normalized ratio1.5, thrombocytopenia50/nl, or both; von Willebrand's disease/hemophilia). Diagnostic mini-laparoscopy with visually guided liver biop…

Predictive role of capillaroscopic skin ulcer risk index in systemic sclerosis: A multicentre validation study

2012

IntroductionThe early detection of systemic sclerosis (SSc) patients at high risk of developing digital ulcers could allow preventive treatment, with a reduction of morbidity and social costs. In 2009, a quantitative score, the capillaroscopic skin ulcer risk index (CSURI), calculated according to the formula ‘D×M/N2’, was proposed, which was highly predictive of the appearance of scleroderma digital ulcers within 3 months of capillaroscopic evaluation.ObjectivesThis multicentre study aims to validate the predictive value and reproducibility of CSURI in a large population of SSc patients.MethodsCSURI was analysed in 229 unselected SSc patients by nailfold videocapillaroscopy (NVC). All pati…
