[Severe form of herpes gestationis].

We report a very severe form of herpers gestationis that arose at the 26(th) week of pregnancy and reached us for observation at the 30(th) week. Herpes gestationis in an autoimmune vesicobullous dermatosis characterised by skin eruptions, intense itching and consequent increase in fetal morbility, with delayed intrauterine growth and prematurity. Owing to its particular severity (involvement of the entire body surface including the face), between the 30th and the 32(nd) weeks we had to address a severe clinical condition characterised by anaemia, marked hypoproteinaemia, hypoalbuminaemia, hupertension and hyperglycaemia which led us to resort to the maximum dose of oral corticotherapy in association with topical therapy using clobetasol propionate. In our opinion the results obtained were highly statisfactory with the result that at the end of the 37(th) week, in consideration of the patient's obstetric history, podalic presentation and parity, we performed a Caesarean delivering a newborn of 3000 g in excellent condition. The patient was discharged symptom-free on the 6(th) day and the newborn was in full healt.

Benign metastasizing leiomyoma in the lung: a case report.

The authors report a rare case of leiomyomatosis of the lung diagnosed in a women with uterine leiomyomatosis not previously treated. The absence of mitosis with nuclear atypism in all histological samples opens the question of whether the origin of the tumor in the lung was from uterine leiomyomas metastasizing or multifocal amarthomas, synchronous or metachronous. Hamartomas or real metastasis of uterine leiomyomas? The response to GnRH analogue treatment was evaluated.

The European ST-T database: standard for evaluating systems for the analysis of ST-T changes in ambulatory electrocardiography.

The project for the development of the European ST-T annotated Database originated from a 'Concerted Action' on Ambulatory Monitoring, set up by the European Community in 1985. The goal was to prototype an ECG database for assessing the quality of ambulatory ECG monitoring (AECG) systems. After the 'concerted action', the development of the full database was coordinated by the Institute of Clinical Physiology of the National Research Council (CNR) in Pisa and the Thoraxcenter of Erasmus University in Rotterdam. Thirteen research groups from eight countries provided AECG tapes and annotated beat by beat the selected 2-channel records, each 2 h in duration. ST segment (ST) and T-wave (T) changes were identified and their onset, offset and peak beats annotated in addition to QRSs, beat types, rhythm and signal quality changes. In 1989, the European Society of Cardiology sponsored the remainder of the project. Recently the 90 records were completed and stored on CD-ROM. The records include 372 ST and 423 T changes. In cooperation with the Biomedical Engineering Centre of MIT (developers of the MIT-BIH arrhythmia database), the annotation scheme was revised to be consistent with both MIT-BIH and American Heart Association formats.

[Technical ambulatory ECG innovations in performance evaluation].

Evaluating the performances of the instrumentation for Ambulatory ECG (AECG) analysis is a need largely recognized by both manufacturers and users. The most generally accepted method is the beat-by-beat comparison with annotated data bases, representing the different ECG abnormalities. Available data bases are aimed at arrhythmias detection evaluation, while it is recognized that the AECG ST-T changes detection has a great relevance in the analysis of ischemic heart disease. A concerted action of the European Community on Ambulatory Monitoring has been approved for achieving a comprehensive reference standard for assessing the quality of AECG instrumentation. The European project has been concentrated on the problem of ST-T analysis. An annotated data base is being developed with the contribution of european experts. A pilot study has been performed for establishing the criteria related to the development and annotation; particularly the definition of significant ST-T changes has been established. The data base will include 2-hour double channel AECG records, which contain at least one ST-T episode. Each record is annotated beat by beat according to the established scheme, identifying arrhythmic beats, rhythm changes, ST-T changes and noisy segments. A coordinating center has been established for interacting with the participating groups and for performing the operations related to the generation and management of the data base. For the time being 14 Groups of 8 Countries are participating to the annotation of the data base. A minimum number of 100 records is planned within June 1988.

[Analysis of the spread of ambulatory electrocardiography in Italy].

The diffusion of ambulatory monitoring (AM) in Italy was evaluated by a questionnaire sent to 102 centers known to be active in this field. The 70 replays obtained constitute this report. In Italy the first center for AM was activated in 1970, thereafter many other new centers started with the maximal increase between 1978 and 1983. During 1985 these centers performed 36223 examinations (mean 517) with a great variability in the number of examinations performed per year: 11 centers performed greater than 1000 examinations a yr, 21 greater than 500 less than 1000 and 38 less than 500. This variability was independent by the number of recorders each center have (on average 4.78 per center) and by the number of personnel involved in the activity. Waiting list resulted to be 25 days on average (1.90) and 4.7 days were needed for the replay (1.20). The main complain resulted to be the difficulty to obtain in short period of time technical assistance. In the second part of the questionnaire more clinical questions were asked. AM resulted to be required the most for arrhythmias and ischemic heart disease whereas atypical chest pain, palpitations and lipothymia events were considered to be the major reasons for a negative examination. In conclusion our data allow to identify the clinical relevance of AM in Italy and its major applicants.
