Molecular Progression in Unusual Recurrent Non-Pediatric Intracranial Clear Cell Meningioma
2017
We report a case of a recurrent clear cell meningioma (CCM) in the frontal lobe of the brain of a 67-year-old man. The patient developed three recurrences: at 3, 10, and 12 years after his initial surgery. Histopathology observations revealed a grade 2 CCM with positivity for vimentin and epithelial membrane antigen. Expression of E-cadherin was positive only in the primary tumour and in the first available recurrence. Fluorescence in situ hybridization analyses demonstrated 1p and 14q deletions within the last recurrence. Multiplex ligation-dependent probe amplification studies revealed a heterozygous partial NF2 gene deletion, which progressed to total loss in the last recurrence. The las…
The role of stress in the onset of depressive disorders
2002
Background: We conducted the present study to evaluate the impact of stressful events on the onset of depressive disorders in a Spanish clinical sample, compared to a control group matched for age, sex, civil status and social class. We compared our results with those of other studies carried out with samples that were both clinically and culturally similar to ours. Method: Fifty depressed patients that were diagnosed with a depressive episode in the 6 months prior to the interview and 50 healthy controls were included in the study. Both groups were compared on the “Life Events and Difficulties Schedule” (LEDS). Results: Of the depressive patients, 68 % compared to only 18 % of the control …
Recent epidemiological studies on ionizing radiation and childhood cancer in Germany.
1998
The results from recent epidemiological studies based on the German Childhood Cancer Registry are summarized.An oecological study covers 16 years' incidence of childhood malignancies in areas surrounding nuclear facilities and in matched control regions. Two population-based case control studies explore potential risk factors of childhood leukaemia in the state of Lower Saxony (1988 93) and in all western states of Germany (1992-94).There was no increased incidence of childhood leukaemia and other malignancies in the vicinity of nuclear installations. X-ray examinations during pregnancy and in early childhood were not associated with an increased risk of childhood leukaemia. There were no d…
Hypothenar hammer syndrome: A multicenter case-control study
2013
Background The rarely diagnosed hypothenar hammer syndrome (HHS) is due to vascular damage to the distal part of the ulnar artery probably caused by acute or repetitive blunt trauma to the hypothenar region. To date, mainly case reports have been published, while epidemiological data are almost absent. Aim To identify potential risk factors for HHS. Method An interview-based multicenter case–control study of 71 patients with HHS and 105 matched controls was conducted with standardized questions regarding disease specific variables, occupation, exposure of the hands to different types of trauma in occupational and leisure context. Medical data were verified from individual medical records. R…
Intermittent hyperammonemic encephalopathy after ureterosigmoidostomy: spontaneous onset in the absence of hepatic failure
2015
Intermittent hyperammonemic encephalopathy after ureterosigmoidostomy is a rare, but if unrecognized, potentially lethal condition. Ureterosigmoidostomy was performed in a male patient with bladder extrophy. After 35 years, he developed hyperammonemic encephalopathy. Diagnostic procedures did not reveal hepatic nor metabolic disorders. Despite administration of preventive medical treatment, several episodes recurred. A durable prevention was finally achieved by conversion into an ileal conduit. Intermittent hyperammonemic encephalopathy can occur decades after ureterosigmoidostomy. In the case of absence of metabolic disorders and resistance to medical treatment, conversion into a urinary d…
Height as a potential indicator of early life events predicting Parkinson's disease: A case-control study
2007
Aim of this study was to investigate the relationship between height in young adult age and Parkinson's disease (PD) risk. We included 266 persons affected by idiopathic PD. Patients were matched by age and sex to 266 controls by a random selection from the municipality of residence. We collected information about height preceding PD from official documents where these characteristics referred to young adult age (nearly 30 years). We compared height in cases and controls by calculating differences in mean distribution and by χ2 analyses. Crude and adjusted odds ratios (OR) and 95% confidence intervals (CI) were calculated by logistic regression models. Mean height was significantly lower in…
A rare case of infrarenal aortic coarctation in a young female
2020
Abstract Introduction Infrarenal abdominal aortic coarctation (AAC) is an extremely rare disease. It can be associated with renal artery stenosis determining secondary renal hypertension. Presentation of case We report a case of AAC in young female patient presenting systemic hypertension non-responder to medical treatment. Diagnostics revealed the involvement of the right renal artery as the cause of hypertension. The management consisted of percutaneous renal artery stenting and close surveillance for the aortic segment. The treatment was uneventful with resolution of the hypertensive condition. Discussion AAC etiology is unknown. There are no studies comparing the long-term treatment out…
A Novel Technique of Posterolateral Suturing in Thoracoscopic Diaphragmatic Hernia Repair
2017
Background Closure of the posterolateral defect in some cases of congenital diaphragmatic hernia (CDH) can be difficult. Percutaneous transcostal suturing is often helpful to create a complete, watertight closure of the diaphragm. A challenge with the technique is passing the needle out the same tract that it entered so that no skin is caught when the knots are laid down into the subcutaneous tissue. This report describes a novel technique using a Tuohy needle to percutaneously suture the posterolateral defect during thoracoscopic repair of CDH. Case We report a case of a 6-week-old infant who presented with a CDH and ipsilateral intrathoracic kidney that was repaired using thoracoscopic a…
Duodenal perforation as presentation of gastric neuroendocrine tumour: A case report
2020
Highlights • Gastric neuroendocrine neoplasms (g-NENs) represent the most frequent digestive NENs and are increasingly recognized thanks to diffusion of upper gastrointestinal endoscopy. • g-NENs can be sporadic or associated with multiple endocrine neoplasia type 1 (MEN-1) and present with a functional Zollinger-Ellison syndrome. • We described a case of a 60 years old Caucasian male came to emergency room with diffuse abdominal pain and leukocytosis on blood tests. • At the level of the pyloric portion we found irregularly thickened walls associated with a small fluid collection and bubbles of free air. On exploratory laparoscopy we found a large perforation (about 5 cm of size) in the fi…
Diagnostic accuracy of clinical parameters to monitor peri-implant conditions: A matched case-control study
2018
International audience; Background: The aim of this case-control study was to estimate the diagnostic accuracy of the standard clinical parameters in diagnosing healthy peri-implant tissues, peri-implant mucositis, and peri-implantitis.Methods: A case-control study was designed to compare the clinical parameters used in the diagnosis of peri-implant diseases such as: probingdepth (PD), bleeding on probing (BOP), mucosal redness (MR), suppuration (SUP), and plaque index (PI). Furthermore, the influence of patient-(sex, age) and implant-related variables (implant neck configuration, time in function after loading) were evaluated to investigate the association with the clinical findings. The i…
