Malignant peripheral neuroectodermal tumors in urology.
1995
During the past few years, a new tumor type has emerged in the pediatric and adolescent group of cancer patients, which has been designated malignant peripheral neuroectodermal tumor (MPNT). This tumor has some clinical and pathological signs in common with either soft-tissue sarcomas or classic Ewing's sarcoma, but is defined as a distinct entity because of its immunohistological characteristics. The tumor expresses neuronal markers, but the pattern varies: chromogranin, neuron-specific enolase, synaptophysin, protein S-100 and others. MPNT can occur in the urogenital region. The differential diagnosis on clinical grounds must include Ewing's and soft tissue sarcomas, and also Wilms' tumor…
Behavior of Epithelial Differentiation Antigens (Carcinoembryonic Antigen, Epithelial Membrane Antigen, Keratin and Cytokeratin) in Transitional Cell…
1992
Results of an immunohistochemical study in normal urothelium and transitional cell carcinomas of the bladder are presented. Paraffin-embedded material was confronted with immunoantisera against carcinoembryonic antigen (CEA), keratin (K), cytokeratin (CK) and epithelial membrane antigen (EMA). Immunohistochemical findings confirm the changes in reactivity of dysplastic urothelium and carcinoma in situ for CEA, CK and EMA, in comparison with normal urothelium. Statistically significant differences were also found, depending upon tumor stage, in staining of transitional cell carcinomas for K and CK. Expression of CK correlated with the tumor differentiation grade: normal urothelium and well-d…
Extra-Adrenal Adult Neuroblastoma With Aberrant Germ Cell Marker Expression: Maturation After Chemotherapy as an Important Clue to a Challenging Diag…
2019
Adult neuroblastoma is an extremely infrequent neoplasm, usually occurring in the adrenal medulla or in the paraspinal sympathetic ganglia, as its childhood counterpart. We report a very unusual case of a Schwannian stroma-poor adult neuroblastoma of inguinal location, showing aberrant expression of germ cell markers: SALL4 and OCT4. This aberrant marker expression, the unusual positivity for NKX2.2 and the very scattered (instead of diffuse strong) PHOX2B expression, complicated the initial diagnosis. In this case, the posttreatment histological evaluation revealed the neuroblastic nature of the lesion. Neuroblastoma maturation after treatment is an unusual finding in adults, and in this …
The early clinical phenotype of Fabry disease: a study on 35 European children and adolescents.
2003
Fabry disease (FD) is a debilitating progressive multisystem X-linked lysosomal storage disorder. It was generally believed that the disease affects only adult males. Through systematic pedigree analysis, we identified 35 paediatric FD patients (age 1 to 21 years, mean 12.6 years) in 25 families. Predominant signs in this cohort were: acroparesthesia, hypohidrosis, and cornea verticillata. Neurological and psychological changes, such as tinnitus, recurrent vertigo, headache, diminished level of activity, fatigue, and depression were often observed. Angiokeratoma and gastrointestinal symptoms were frequent. Some patients also showed cardiac abnormalities. Six children and adolescents (three …
A nationwide survey of hereditary angioedema due to C1 inhibitor deficiency in Italy
2014
Introduction Hereditary angioedema due to C1-inhibitor deficiency (C1-INH-HAE type I) or dysfunction (C1-INH-HAE type II) is a rare disease characterized by recurrent episodes of edema with an estimated frequency of 1:50,000 in the global population without racial or gender differences. In this study we present the results of a nationwide survey of C1-INH-HAE patients referring to 17 Italian centers, the Italian network for C1-INH-HAE, ITACA. Methods Italian patients diagnosed with C1-INH-HAE from 1973 to 2013 were included in the study. Diagnosis of C1-INH-HAE was based on family and/or personal history of recurrent angioedema without urticaria and on antigenic and/or functional C1-INH def…
Effects of age on depressive symptomatology and response to antidepressant treatment in patients with major depressive disorder aged 18 to 65 years
2020
Background: There is evidence that symptomatology in patients with major depressive disorder (MDD) changes with age. However, studies comparing depressive symptomatology between different age groups during antidepressant therapy are rare. We compared demographic and clinical characteristics in depressed patients of different age groups at baseline and during treatment. Methods: 889 MDD inpatients were divided into four age groups (18–29, 30–39, 40–49, 50–65 yrs.). Demographic and clinical characteristics including depressive symptomatology (assessed by the Inventory of Depressive Symptoms) were assessed at baseline and weekly during treatment. Results: At baseline, young patients (18–29 yea…
Brief depression among patients in general practice
1994
Depression with substantial psychosocial impairment, but not qualifying as depressive disorder according to the standard diagnostic manuals, is frequent among primary care patients. Recurrent brief depression (RBD) is a diagnostic category intended to identify a major proportion of this group of patients. The WHO study on "Psychological Problems in Primary Health Care" was used as a vehicle to estimate the proportion of patients with this diagnosis and to evaluate the validity of this diagnosis as well as of alternative concepts of brief depression with multiple episodes. This study applies a two-stage sampling scheme; 300 patients also underwent an additional interview tailored for variant…
Remission in schizophrenia — What are we measuring? Comparing the consensus remission criteria to a CGI-based definition of remission and to remissio…
2019
Despite being recommended for use in clinical trials, the consensus remission criteria were found to leave patients with persisting symptoms, relevant areas of functional impairment and a decreased sense of wellbeing. Therefore, to evaluate the appropriateness of the schizophrenia consensus criteria, a definition of remission based on the Clinical Global Impression Scale (CGI) was developed and remitter subgroups were compared.239 patients with a schizophrenia spectrum disorder were evaluated regarding their remission status after inpatient treatment. Remission in schizophrenia was defined according to the symptom-severity component of the consensus criteria by Andreasen et al. and a CGI ba…
Poor patient awareness and frequent misdiagnosis of migraine: findings from a large transcontinental cohort.
2019
Background and purpose Although migraine is the second most disabling condition worldwide, there is poor awareness of it. The objective was to assess the awareness of migraine and previous diagnostic and therapeutic consultations and treatments in a large international population of migraineurs. Methods This was a multicentre study conducted in 12 headache centres in seven countries. Each centre recruited up to 100 patients referred for a first visit and diagnosed with migraine. Subjects were given a structured clinical questionnaire-based interview about the perceptions of the type of headache they suffered from, its cause, previous diagnoses, investigations and treatments. Results In all,…
Pancreatic encephalopathy: a 7-year follow-up case report and review of the literature
2003
Pancreatic encephalopathy is a rare complication of acute pancreatitis. Clinical features include focal neurological signs and acute onset of dementia. This picture can fluctuate over time: cyclic progression with remission and relapses has been described. We present the case of a 43-year-old man who, after an acute episode of pancreatitis, experienced five relapses, with alternating focal signs. The patient has improved, but cognitive impairment persists after a 7-year follow-up.
