Some aspects of the pathophysiology of hypertrophic cardiopathies. An echocardiographic computerized study.

35 patients, of them 10 with aortic stenosis, 7 with idiopathic hypertrophic subaortic stenosis, 6 with asymmetric septal hypertrophy, and 12 with systemic hypertension were examined with the aim of a pathophysiological differentiation of various hypertrophic cardiopathies. The authors' own ECE digital echocardiographic system was used. The results attest to an abnormal diastolic function in hypertrophic cardiopathies. At the same time, the diastolic compliance is less affected in symmetric cardiopathies, even in their more advanced clinical stage, than in asymmetric ones.

Decrease in toxic potential of mixed tensides maintained below the critical micelle concentration: an in vitro study.

Sodium lauryl sulphate (SLS) is an anionic tenside widely utilized in commercial topical preparations that may cause skin irritation. It has been shown that the barrier damage caused by SLS in vivo is lower when SLS is used in combination with other tensides which are able to reduce the critical micelle concentration (CMC). The aim of our study was to evaluate if the cytotoxic effect of SLS is reduced by the association with different tensides also at concentrations well below the CMC. Normal human keratinocytes from plastic surgery were grown in serum-free medium. At subconfluency, the cells were treated with SLS at a dose of 0.0025% in combination with cocamidopropyl betaine, Tween 20 and Tween 80 at the minimum toxic dose. Following tenside treatment, the culture medium was changed, and after 24 h the cells were collected for (3)H-thymidine incorporation, the MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide) assay and neutral red (NR) uptake. The cytotoxic effect on normal human keratinocytes, as evaluated by (3)H-thymidine incorporation, MTT assay and NR uptake, was significantly decreased by the combination with all the tested tensides. The correlation between cytotoxicity and physical properties was also studied by a conductimetric assay to investigate the mechanism involved in this toxicity reduction.

[Non-traumatic rhabdomyolysis: clinical and laboratory diagnosis, assessment of renal complications].

PURPOSE: Non traumatic rhabdomyolysis (RML) is an infrequent and sometimes clinically silent syndrome. RML incidence is increasing in the last few years. A prospective study was performed: 1) to value the non traumatic RML incidence in patients admitted to Emergency Room; 2) to reevaluate the clinical and laboratory criteria of diagnosis; 3) to establish complications' incidence and prognosis during the recovery. PATIENTS AND METHODS: In Emergency Medical First Aid 15.301 patients were examined. To the study were admitted only patients having CK level grater than fivefold the upper normal limits and without trauma, recent surgery, heart and cerebral disease. RESULTS: During the six months study, non traumatic RML incidence was 0.1% (16 patients of 15.301). Drugs, alcohol and substance abuse acute intoxication were the commonest causes. The Acute Renal Failure (ARF) was the more frequent complication (9 patients of 16). Four patients of nine was treated only by fluid administration, the other five by dialysis. Oligoanuric-ARF appeared only in patients affected by toxic RML. These patients had no-return to normal renal functional values at the time of hospital discharge. CONCLUSIONS: Non traumatic RML should be take into account by emergency doctor in cases of acute intoxication. To prevent the complications it's necessary the right interpretation of clinical and laboratory datas and an early and adequate therapy.

[Professional accreditation of emergency care services. Experience of the polyclinic "Umberto I" of Rome].

Professional Accreditation can be seen as a Quality Improvement/Assurance Program for the delivery of Medical and Nursing Care, through organizational analysis to determine the level of compliance to specific criteria, correlated with satisfactory assistance processes. We report the experience of a professional accreditation process of an Emergency Department within a University Hospital in Rome, with high level assistance facilities. Voluntary interdisciplinary working groups were formed and working process was decomposed, as Quality Assurance Programs propose, so that critical points in each phase could be pointed out and hypothesis for improvements could be advanced for subsequent operative planning of changes. This method was used and applied to analyze the Emergency Department's "mission", clearing the goals of department, accordingly with the hospital's management mandate, and therefore permit the assessment of the level of compliance to quality indicators. Results of the different phases and critical analysis of all the steps are described.

[The nurse's role in the identification and management of alcohol abuser in the Emergency Department].

The emergency department (ED) nurse plays a major role both in recognizing and in the management of the patients affected by alcohol related problems, such-as acute alcohol intoxication (AAI), alcohol withdrawal (AW), traumatic or spontaneous illness due to acute or chronic effects of alcohol abuse. Here are described both the clinical problems and the diagnostic instruments that nurse can use in ED to increase diagnostic sensibility. Furthermore both clinical features of AAI in relation with blood alcohol concentration (BAC), diagnostic criteria and test to evaluate AW severity are reported in this review. Even diagnostic instruments to identify alcohol abuse also in trauma are reported: the alcohol breath test, BAC and laboratory test. Even the Alcohol Use Disorders Identification Test (A.U.D.I.T.) questionnaire is reported to recognize the alcohol abuser. In conclusion acquiring a specific training, nurse can play a major role in the complex intervention net of alcoholics rehabilitation.

[Computers in emergency medicine].

Computer's applications in emergency medicine are reviewed. In the Emergency Health Care computer science provides support to the solution of medical problems (with diagnostic and medical decision making softwares) and to the management of emergency departments. Computer interfaced to instrumental equipments allows the monitoring of biomedical signals and their transmission at distance. Finally, the possibilities of computer-aided instruction are presented. Teaching methods such as the tutor-system and the simulation are discussed.

[Acute emphysematous cholecystitis].

A case of acute cholecystitis in a patient of 66 is reported. The aetiopathogenetic aspects are examined with particular regard to the microbiology of such forms, the particular radiological and anatomo-pathological findings and the medical and surgical implications, in the light of a review of the question.
