Prevalence and incidence of schizophrenic disorders in Portogruaro. An Italian case register study.

The authors report a study of treated prevalence and incidence of schizophrenic and related functional psychoses in an area of northeastern Italy (Portogruaro), based on case-register data. Point, 1-year, and lifetime prevalence as well as incidence rates on the adult population for a broad ICD-9 diagnosis of schizophrenia are given. Data over an 8-year period show the incidence around .2/1000, point prevalence around 1.4, 1-year prevalence of 2.7, and lifetime prevalence around 5.2. The rates peak in the 45 to 64 age group on all measures of prevalence. The implications of these findings are discussed in the light of methodological issues in epidemiological studies of schizophrenia and comparisons are made with figures from other countries.

Diverticulosis of the main bronchi: a rare cause of recurrent bronchopneumonia in a child.

Diverticulosis of the main bronchi, not associated with other organ abnormalities, developed in a 12 year old child. This abnormality caused recurrent bronchopneumonia in the lung with the main bronchi diverticulosis. Fibreoptic bronchoscopy helped to locate the lesion and selective bronchography, with injection of contrast medium through the suction channel of the fibreoptic bronchoscope, showed the morphology of this rare malformation.

Recent trends in mental health services in Italy: an analysis of national and local data.

This paper reviews trends in Italian mental health services after the implementation of the 1978 Mental Health Act. Data available at the national level on public and private inpatient services, community mental health centres, residential and day care facilities are presented and discussed. Findings from two case-register areas, where comprehensive community services according to the Mental Health Act have been implemented, are discussed. Public mental hospitals are no longer used for psychiatric treatment, except for a small number of long stay patients. General hospital psychiatric units are the only setting in the public sector where psychiatric patients can be admitted. In private mental hospitals, the number of residents has decreased, while admissions have remained stable. However, community services are unevenly distributed and residential facilities are generally lacking. Little is known about quality of care provided, although data from some pilot studies are encouraging. Stable admission rates to forensic mental hospitals suggest that the criminalization of mentally ill has not increased. The effect of changing patterns of mental health care on suicide rates are discussed.

Patterns of aftercare for psychiatric patients discharged after short inpatient treatment. An Italian collaborative study.

This is the first of a series of papers presenting the results of an Italian collaborative study on psychiatric inpatient service utilisation. Patterns of care of a large sample of patients discharged after short inpatient treatment are discussed in the light of the changes introduced by the 1978 Mental Health Act in the Italian psychiatric care delivery system. Three closely related issues are considered: a) use of psychiatric hospitalisation, b) relationships between inpatient and community treatment before and after an admission episode, c) continuity of care. The main findings are: 1) great variability between services suggests that local factors play an important role in determining the contents of care in Italian post-reform psychiatry. 2) The relationship between inpatient and community services is complex, partial integration being the most common picture. 3) Psychiatric hospitalisation is the entry point into the care system for a sizeable group of patients. 4) Continuity of care is achieved for half the patients, mostly with diagnoses of severe mental disorders. 5) Subjects with a recent history of revolving door behaviour or a past history of mental hospital admission show the highest likelihood of remaining in community care following discharge.

Outcome of discharged psychiatric patients after short inpatient treatment: an Italian collaborative study.

This paper presents the results of an Italian multicentre study on the 6-month outcome of psychiatric patients discharged after short-term in-patient treatment from 21 general hospital psychiatric units. Two outcome measures were used: relapses (defined as readmissions for psychiatric treatment or suicide) and community tenure. The data showed, on average, a fairly high relapse rate (43% in 6 months) combined with a good community tenure. The findings are discussed in the light of the heterogeneity in patterns of care provision observed in Italian psychiatric services after the changes introduced by the 1978 Mental Health Act, reported in a previous paper.

Early and rapid diagnosis of CMV infection by nonradioactive in situ hybridization in pediatric kidney transplant recipients.

A nonradioactive in situ hybridization technique was utilized for the rapid and early diagnosis of cytomegalovirus (CMV) infection in children undergoing kidney transplantation. The cellular samples were obtained directly from the organs thought to be affected on the basis of clinical findings: bronchoalveolar lavage during interstitial pneumonia (7 samples from 6 cases); fine-needle aspiration biopsy (FNAB) of the liver during acute hepatitis (1 case); kidney FNAB and peripheral blood where there was a greater than or equal to 25% creatinine rise with or without fever (26 episodes). Standard virus isolation procedures and an immunofluorescent technique on short-term cultures of human fibroblast cells were performed as a control. 6/23 children followed had a symptomatic CMV infection (4 had interstitial pneumonia; 1 had acute hepatitis, and there was 1 case of creatinine rise with fever). In all cases, the diagnosis was provided by in situ hybridization in less than 24 h. These results were confirmed 48 h later by immunofluorescence and after 5-25 days by standard viral cultures. In situ hybridization with a biotinylated probe proved to be a rapid and sensitive method for diagnosis of CMV disease, when performed on specimens obtained from the involved organs at an early stage of the infection. This diagnostic approach allowed a specific antiviral therapy to be undertaken promptly.

[Cardiac manifestations of hyperthyroidism in the elderly].

PURPOSE: To evaluate the cardiocirculatory abnormalities of hyperthyroidism in the elderly. PATIENTS AND METHODS: Twenty-four hyperthyroid patients, 18 women and six men, aged 60 to 87 (average 73.5) years were studied. Seventeen (70.9%) patients had associated cardiocirculatory diseases. The evaluation was made on clinical grounds complemented by electrocardiographic, radiologic, phonomechanocardiographic and echocardiographic examinations. RESULTS: Cardiocirculatory symptoms were observed in 17 (70.9%) patients and congestive heart failure in nine (37.5%) of them. The electrocardiogram was abnormal in 20 (83.3%) patients and the tachyarrhythmias were the commonest abnormality (62.5%). Eight (33.3%) patients had chronic atrial fibrillation and five (20.8%) had sinus tachycardia. There was no significant statistical difference on the electrocardiograms of patients with and without cardiocirculatory abnormalities. Cardiomegaly was significantly more prevalent in hyperthyroid patients, with (64.7%) or without (57.1%) cardiocirculatory abnormalities, than in normal elderly (23.9%). Left ventricular performance was studied in 14 patients through the systolic quotient and was found normal or high in 12 (85.7%). The percentage of fractional shortening (delta D%) was higher than 30 in all patients. None of the patients was found to have symmetric or asymmetric hypertrophic cardiomyopathy and mitral valve prolapse on echocardiogram. CONCLUSION: Hyperthyroidism in the elderly patient determines frequently cardiocirculatory abnormalities that may be misdiagnosed with those caused by the ageing process or by associated cardiopathies. This diagnosis should be suspected in all elderly patients having tachyarrhythmias and/or cardiac failure resistant to usual therapy, mainly in patients without clear cardiocirculatory pathology.

Follicular cell predominance in the cytologic examination of dominant thyroid nodules indicates a sixty percent incidence of neoplasia.

The interpretation of aspiration cytologic smears that contain a predominance of follicular components often presents a dilemma to the clinician who is treating a patient who has a dominant thyroid nodule, especially when thyroid-stimulating hormone suppression does not produce any significant involution of the dominant nodule. We reviewed a consecutive series of 555 fine-needle aspiration cytologic examinations of dominant thyroid nodules. All specimens that contained colloid or follicular cells mixed with lymphocytes or Hürthle cells were excluded from this review. Additionally, nine aspirates contained degenerated follicular cells with insufficient material for cytologic diagnosis. The remaining 76 specimens contained a predominance of follicular cells: 27 specimens were interpreted as containing "normal" follicular cells, and the remaining 49 specimens were read as "atypical" follicular cells. Histopathologic examination of the resected specimens indicated a 60% incidence of neoplasia (30% carcinoma, 30% adenoma) in which the aspiration cytologic study was interpreted as "normal" follicular cells. On the other hand, a 63% incidence of neoplasia (27% carcinoma, 36% adenoma) occurred in which the cytologic study was read as "atypical." In conclusion, aspirates showing a predominance of follicular cells, whether "normal" or "atypical" indicate a 60% incidence of neoplasia in dominant thyroid nodules that do not decrease significantly in size with thyroid-stimulating hormone suppression.

[Prenatal diagnosis of congenital heart diseases and cardiac arrhythmias by Doppler echocardiography].

PURPOSE: To detect in prenatal life fetal arrhythmia and congenital heart disease. We performed fetal echocardiography following classical indications according to the literature. PATIENTS AND METHODS: Two-dimensional echocardiography associated with M-mode and Doppler was performed in 200 patients according to the indications: maternal diabetes, fetal arrhythmia, maternal congenital heart disease, previous fetus with cardiac defect, intrauterine growth retardation, nonimmune fetal hydrops, rubeola, isoimmunization, fetal malformation by ultrasound, polyhydramnios, gemelarity, oligohydramnios, maternal ingestion of drugs, lupus and others. RESULTS: Structural abnormalities of the heart were found in 6 cases and associated with bradiarrhythmia in 5 cases (total of 5.5%). Fetal arrhythmias without cardiac malformation were found in 35 cases (17.5%) and premature atrial contractions were the most frequent. CONCLUSION: The findings in this study indicate that it is possible the accurate definition of the cardiac anatomy and function. We have emphasized the method trying to spread it, objecting to improve assistance to the fetus and newborn with arrhythmias and/or congenital heart disease.

[The importance of mitral calcification in the elderly].

The echocardiographic study of 480 patients over 60 years (medium age: 75.4) revealed 37 (33 women) of them having mitral calcification (MC). The analysis of clinical and metabolic data of these 37 patients plus their electro, phono and echocardiographic assessment revealed: 1) MC was observed in 7.7% of this elderly population and its incidence tended to increase with age; 2) MC was more frequent and more pronounced in women; 3) cardiocirculatory abnormalities responsible for a high systolic pressure in the left ventricle, such as hypertension (64.9%) and aortic stenosis (10.8%) were the most commonly associated cardiac pathologies; 4) no history of illnesses usually aggressive to the mitral valve was detected; 5) plasma lipids and calcium were normal; 6) in 27.0% of patients with MC there was some degree of mitral stenosis and/or insufficiency and surgical correction has been considered in some cases; 7) changes in production and/or conduction properties were frequent, causing bradyarrhythmias, tachyarrhythmias and intraventricular block. Taking these points into consideration, a careful follow-up of confirmed cases is suggested, in order to detect and treat any complications without delay.

Adult nesidioblastosis. An unusual cause of fasting hypoglycemia.

Laidlaw coined the term nesidioblastosis in 1938 to characterize the neodifferentiation of the islet cells of Langerhans from pancreatic duct epithelium. It is well recognized in the pediatric population as a frequent cause of persistent neonatal hypoglycemia. However, its occurrence in adults is presumed to be rare and, therefore, it is not appreciated as a cause of hyperinsulinism. Three women, aged 29, 42, and 63, with adult onset hyperinsulinism secondary to nesidioblastosis are reported. All three patients required near-total pancreatectomy. The preoperative findings were consistent with hyperinsulinemic hypoglycemia as with insulinomas. Results of pancreatic imaging studies were normal in two patients and one patient had a pancreatic examination by computerized tomography and magnetic resonance imaging, with false-positive results. Two of the three patients had previously undergone a 50 per cent distal pancreatectomy in which the resected specimens were interpreted as normal in one patient and consistent with nesidioblastosis in the second. Both patients subsequently developed recurrent symptomatic hyperinsulinemic hypoglycemia that persisted despite dosage adjustments in diazoxide therapy. The oldest patient underwent a 95 per cent pancreatectomy at the initial surgical exploration because an insulinoma could not be identified. The other patients underwent a completion 95 per cent pancreatectomy. In both, histochemical examination of each specimen disclosed nesidioblastosis, characterized by clusters of islet cells interspersed throughout the exocrine tissue.

Comparison of graduates of regular curriculum and unified basic-science-clinical curriculum.

The purpose of the study reported here was to identify differences between graduates who were in different curricula at Loyola University of Chicago Stritch School of Medicine. The physicians who had been in the special track, which combined the basic and clinical sciences throughout the program, chose specialties in family practice and psychiatry more than the regular track students and more often were salaried. One-third of those in the special curriculum felt the greatest strength of their medical school training was the preparation for independent learning, and a majority viewed a practice in which there were uncertainties in diagnosis as desirable. The traditional program graduate preferred to deal with cases in which important decisions had to be made rapidly and the effects of treatment could be immediately addressed. The two groups disagreed as to who should have major control of health care, on issues of peer review in the office, and on the emphasis physicians should give preventive care.

Modification of bronchial hyperreactivity during pollen season in children allergic to grass.

Ten children, sensitive to grass pollens with seasonal rhinitis and mild asthma, underwent bronchial challenge with carbachol in the pre-seasonal, seasonal, and post-seasonal period. According to pollen count, we observed significant differences between pre-seasonal, seasonal, and post-seasonal values. Also basal FEV1 values varied in the same fashion. Seven of the ten children also participated in a previous similar study in 1984, at which time they did not demonstrate significant variations to bronchial challenge. We wish to emphasize the importance of pollen concentration in the atmosphere as well as the existence of a threshold value of grass pollen necessary for a significant modification in bronchial reactivity to occur.
