Symptoms, course, and complications of abdominal attacks in hereditary angioedema due to C1 inhibitor deficiency.
2006
Recurrent abdominal attacks belong to the cardinal and most distressing symptoms of hereditary angioedema (HAE) due to C1 inhibitor deficiency. They are characterized by crampy pain, but may include vomiting, diarrhea, and other features. Detailed clinical data about the symptoms and course of abdominal attacks have not been reported.We retrospectively observed a total of 33,671 abdominal attacks in 153 patients with HAE including a prospectively examined subgroup of 23 patients. Symptoms, course, frequency of attacks, and complications were analyzed.The relation of mild, moderate, and severe attacks was 1:1.4:5.6 in the prospective part of the study. Extra-abdominal symptoms preceded the a…
Simultaneous sodium lauryl sulphate testing improves the diagnostic validity of allergic patch tests. Results from a prospective multicentre study of…
2005
Summary Background There is evidence that a higher skin susceptibility may induce nonspecific erythematous or weak positive reactions to contact allergens in patch testing. Objectives To evaluate whether simultaneous application of sodium lauryl sulphate (SLS) along with diagnostic patch tests with contact allergens can provide information regarding skin irritability which may help to discriminate allergic from nonspecific irritant reactions to contact allergens. Methods Between July 2001 and June 2003, this prospective study collected patch test data of 5971 patients from 19 centres in Germany and Austria in the Information Network of Departments of Dermatology (IVDK). In addition to co…
Ruptured angiomyolipoma of the kidney: a rare differential diagnosis of flank pain.
2017
Angiomyolipomas (AMLs) of the kidney are typically benign and rare, with an incidence of 2% of all renal masses [1]. They are associated with tuberous sclerosis in about 20% of cases. If ruptured, ...
Bipolar spectrum disorders in a clinical sample of patients with Internet addiction: hidden comorbidity or differential diagnosis?
2015
Background and Aims Behavioral addictions and bipolar disorders have a certain probability of co-occurrence. While the presence of a manic episode has been defined as an exclusion criterion for gambling disorder, no such exclusion has been formulated for Internet addiction. Methods A clinical sample of 368 treatment seekers presenting with excessive to addictive Internet use was screened for bipolar spectrum disorders using the Mood Disorder Questionnaire. Psychopathology was assessed by the Symptom Checklist 90R and a clinical interview was administered to screen for comorbid disorders. Results Comorbid bipolar disorders were more frequent in patients meeting criteria for Internet addictio…
The distinction of bipolar II disorder from bipolar I and recurrent unipolar depression: results of a controlled family study.
1993
The aim of the study was to differentiate bipolar II, bipolar I and recurrent unipolar depression by their familial load for affective disorders. Eighty bipolar, 108 unipolar, 80 control subjects and interviewed first-degree relatives were diagnosed according to Research Diagnostic Criteria using the Schedule for Affective Disorders and Schizophrenia – lifetime version. The morbid risks for bipolar I disorder were equivalent in relatives of bipolar I (3.6%) and bipolar II (3.5%) subjects and lower in relatives of unipolar subjects (1.0%). The morbid risks of relatives for bipolar II disorder distinguished bipolar II subjects (6.1%) from bipolar I subjects (1.8%), from unipolar depressives (…
Screening for congenital renovascular hypoplasia and renal artery stenosis by acute converting enzyme inhibition.
1993
To evaluate the usefulness of the captopril test for identifying renal artery stenosis (RAS) and renovascular hypoplasia (RAH), we studied 48 hypertensive patients. In 20 hypertensives with screening procedures indicating renovascular disease and in 28 essential hypertensives (EH), the plasma renin activity (PRA) responses to an oral test dose of captopril (50 mg) were studied. A 60-min post-captopril PRA increase of 150% (or 400% if baseline PRA < or = 3 ng/ml/h) was considered as positive. Renal angiography was performed in all cases. Among the 20 renovascular hypertensive patients, RAH in 9 and RAS in 11 subjects were proved by angiography. The captopril test in all patients with RAH res…
Safety and Feasibility of a New Minimally Invasive Diagnostic Laparoscopy Technique
1998
Background and Study Aims: Laparoscopy combined with guided liver biopsy offers many advantages in the diagnosis and staging of chronic liver diseases and is superior to other diagnostic procedures. We developed a new minilaparoscopic technique and evaluated the utility of this minimally invasive laparoscopic system in the first 320 patients who underwent diagnostic assessment for liver disease or peritoneal carcinosis. Patients and Methods: Between July 1996 and February 1998, minilaparoscopy, with analgesia and sedation was carried out in 320 patients. It was done using a 1.9-mm optical instrument, which was inserted through the same 2.75-mm trocar as the Veress needle used for inflating …
Diagnostic accuracy of plasma glial fibrillary acidic protein for differentiating intracerebral hemorrhage and cerebral ischemia in patients with sym…
2011
Abstract BACKGROUND Glial fibrillary acidic protein (GFAP) is a biomarker candidate indicative of intracerebral hemorrhage (ICH) in patients with symptoms of acute stroke. GFAP is released rapidly in the presence of expanding intracerebral bleeding, whereas a more gradual release occurs in ischemic stroke. In this study the diagnostic accuracy of plasma GFAP was determined in a prospective multicenter approach. METHODS Within a 1-year recruitment period, patients suspected of having acute (symptom onset &lt;4.5 h before admission) hemispheric stroke were prospectively included into the study in 14 stroke centers in Germany and Switzerland. A blood sample was collected at admission, and …
Solitary rectal ulcer: ultrasonographic and magnetic resonance imaging patterns mimicking rectal cancer.
2011
The objective of this study was to analyze a series of solitary rectal ulcer syndrome (SRUS) cases initially diagnosed as rectal cancer. We analyzed all the patients (1996-2008) initially referred to our colorectal unit with a diagnosis of rectal cancer but with a final diagnosis of SRUS. Demographic data, the diagnostic work-up, and treatment details were collected in a prospective database and analyzed retrospectively. Out of the 5035 patients registered in the colorectal unit database, 14 (0.28%) had a final diagnosis of SRUS. Nine of them had an initial diagnosis of rectal cancer. Out of these, six were preoperatively staged with endorectal ultrasound and/or magnetic resonance and were …
Predictive value of the balloon expulsion test for excluding the diagnosis of pelvic floor dyssynergia in constipation
2003
Abstract Background & Aims: The aim of this study was to establish a simple method to exclude the possibility of pelvic floor dyssynergia (PFD) in constipated patients and thus avoid unnecessary expensive physiologic studies. Methods: Patients with suspicion of functional constipation (FC) were studied prospectively between 1994 and 2002, excluding those with severe systemic, psychological, or symptomatic anorectal/colonic disorders or taking medications that might modify symptoms or results of studies. Diagnosis of PFD was established retrospectively by manometric plus defecographic findings according to Rome II criteria. Two groups of patients were identified: FC without PFD (FC group) an…
