[The experience of paramedical personnel in the cardiopulmonary resuscitation of acute cardiac patients].

The cardiac stop as well as the severe despondency of the respiratory function in the recoverable patients is a major medical urgency which causes the immediate death of the patient if efficient measures of cardiorespiratory resuscitation are not correctly and rapidly taken. The authors describe in detail the measures to be taken in such situations, presenting the experience of the medical and nursing staff in the coronary intensive care unit of the Medical Clinic III, in the Clinical Hospital of Bucharest. It is underlined the fact that due to the nature of their tasks, the nursing staff have an essential contribution within the "team work" of the coronary intensive care units.

Influence of temporal lobe lesions on photic-evoked responses in occipital visual areas.

In 20 patients with temporal lobe lesions and 10 controls, the averaged photic-evoked responses (APERs) and their dispersion pattern (DP) were investigated in inion-vertex-lead and bilaterally in inion-parietal leads (I-P3 and I-P4). The patients with temporal lobe lesions, regardless of lesion location in temporal areas, displayed either absence of APER (the whole APER or only the initial components) or a latency increase without amplitude changes. The DP was generally abnormal. The role of the temporal lobe in the organization of APER in visual areas is discussed.

Visual evoked responses and their dispersion pattern in frontal lobe tumours.

In patients with frontal lobe tumours the averaged visual evoked responses (AVER) and their dispersion pattern (DP) in visual areas were investigated before and at different periods after operation. Important changes in AVER (in amplitude and latency) were found in the patients with tumours on the midline or in one of the frontal lobes. The DP was abnormal in all the cases. There was no relation to visual acuity, tumour location and existance of intracranial hypertension. After operation, despite the clinical improvement, the alterations of AVERs or DPs were very marked and in some cases became even more important than before. The role of the frontal lobe in the organization of the responses to peripheral stimuli in the visual areas is discussed.

Neocortical reactivity to peripheral stimuli in neurotics.

The averaged photic-evoked responses (APER) and their dispersion pattern (DP) were investigated in tired subjects, neurotics and patients with neurotic syndromes. The appearance of an ample late negative deflection (N3) followed by a deep positive one (P3) of APER and of an atypical DP in tired subjects, neurotics and in patients with neurotic syndromes, may be considered signs of tiredness and of attention lability. A lengthening of the latencies and decrease in amplitude of different APER components, found in neurotics and in patients with neurotic syndromes only, indicated abnormalities in the function of neuronal structures involved in the organizations of responses to peripheral stimuli.

Visual evoked responses and their dispersion pattern in neurotic patients.

The AVER (averaged visual evoked responses) and the DP (a pattern of dispersion resulting from the variability of each time point locked to the stimulus onset: D = F [T]) were studied in neurotics in comparison with controls. In neurotics without depression and/or anxiety the AVERs were normal and the DPs showed a shortening of the second period; in neurotics with depression and/or anxiety the AVER'S were also normal but the second period of the DPs disappeared.

Age-dependent amplitude variation of brain-stem auditory evoked potentials.

Normative amplitude values of brain-stem auditory evoked potential (BAEP) components are given for normally hearing subjects at 1, 10, 30, 50 and 70 years of age, with an intragroup age variation of only +/- 6 months. Under these circumstances amplitude standard deviations decreased to less than 20% of the mean values. In contrast with the reduced evolution of latency with age, BAEP amplitude (for components I-V) undergoes a greater oscillation during ontogeny. With the exception of component I, it increased markedly from 1 year to 10 years of age and decreased thereafter constantly up to 50 years, with a mean rate of 10 nV yearly. The decrease slowed down between 50 and 70 years. The amplitude differences between the subgroups are highly significant statistically (P less than 0.01). Possible reasons for these changes are discussed.

Anatomo-pathologic observations on epidemic nephropathy.

Two cases of necropsy and 5 cases of renal biopuncture were studied on the occassion of an epidemic of "hemorrhagic fever with renal syndrome" identified in mountainous areas of Transylvania. The prevalent pathogenic process was capillary toxicosis which injured the renal tubules and vessels. The severity of the disease was determined by the phenomena of tubular failure, by the hemorrhagic syndrome and shock.

The diagnostic value of interpleural lymph node biopsy.

The authors examined biopsies of the interpleural lymph nodes harvested by mediastinoscopy and hilloscopy in 162 patients (133 males and 29 females). The diagnostic efficiency is very high in sarcoidosis, silicosis and in Hodgkin's disease. In sarcoidosis biopsy is able to indicate the evolutive stage of the disease. In malignant lymphogranulomatosis all the observations belonged to type II of nodular sclerosis. In bronchial carcinoma interpleural lymph node biopsy may be practised with diagnostic purposes or in order to check up operability.

Morphopathologic changes of enteropathies in 161 children's intestinal endobiopsies.

The authors examined microscopically 161 jejunal biopsies of which 142 presented a pathologic mucosa. The two sexes were equally represented and the prevalent age was between 1 and 2 years. Nearly one third of the cases were acute enteritides and the remaining ones--granulative and atrophic enteritides; none of them was hypertrophic. The causes of these enteropathies are various.
