[Rehabilitation of anoxic brain injured patients after reanimation].

Authors report rehabilitation outcomes of anoxic brain injured patients, following reanimation. In the past 12 years (1988-1999) they treated 54 patients. The patients were selected from other hospitals after successful reanimation, but sustained diffuse anoxic brain injury. The CT and MR examination was generally negative, but small hypodensities were shown rarely (18/54). At the time of admission 21 patients were quadriparetic, 5 patients were hemiparetic, 2 were paraparetic and there were no any paresis in 26 cases. The mean age of the patients was 32 years (7-61). At the time of admission 31 patients were dependent in basic activities of daily living, the mean Barthel Index score was 15 (0-100) but at the time of discharge it was 45 (0-100). 41 patients were discharged into their home and 13 patients had to be transmitted to another hospital for further treating, but later 5 of them died. At the time of discharge only 7 patients had score 100 of the Barthel Index, but they were not able for independent living. Family support, mainly guidance was necessary. Memory deficits, apraxia, attention disturbance, ataxia were the main problems during the rehabilitation process.

Comparison of recoveries of mycobacterium tuberculosis using the automated BACTEC MGIT 960 system, the BACTEC 460 TB system, and Löwenstein-Jensen medium.

Using two different liquid media and one conventional solid medium, a total of 57 mycobacterial isolates (Mycobacterium tuberculosis, n = 55; nontuberculous mycobacteria, n = 2) were recovered from 377 clinical specimens. The rates of recovery of M. tuberculosis were 96. 4% with the BACTEC MGIT 960 liquid medium, 92.7% with BACTEC 12B liquid medium, and 81.8% with the Löwenstein-Jensen (LJ) medium. The mean time to detection of M. tuberculosis in smear-positive specimens was 12.6 days for BACTEC MGIT 960 medium, 13.8 days for BACTEC 12B medium, and 20.1 days for LJ medium, and in smear-negative specimens it was 15.8 days for BACTEC MGIT 960 medium, 17.7 days for BACTEC 12B medium, and 42.2 days for LJ medium. The rates of contamination were 3.7, 2.9, and 1.2% for the BACTEC MGIT 960, BACTEC 12B, and LJ media, respectively. In conclusion, the nonradiometric, fully automated 7-ml BACTEC MGIT 960 system can be considered a viable alternative to the semiautomated, radiometric BACTEC 460 TB system.

[Transbronchial biopsy in diffuse infiltrative lung diseases].

224 transbronchial biopsies were made between 1990 and 1997 in 208 patients suffering diffuse, bilateral, disseminated pulmonary diseases with unidentified origin. The examinations were carried out by flexible bronchoscope with X-ray control after local anaesthesia. The obtained patterns yielded mucous membrane in 15, intact alveoli in 19 percent. In 25 percent of biopsies (57 cases) definitive diagnosis were verifiable. The histological examinations verified the diagnosis of sarcoidosis, hemosiderosis, TB, malignancies, eosinophil pneumonitis etc. In 71 biopsies (62 cases) according to histological opinion were pulmonary fibrosis or some synonyms of these (alveolitis, interstitial fibrosis). From these latter cases the documentation of 18 patients were insufficient, but the data of 44 cases were available. 7/44 carcinosis, 3/44 inactive TB, 8/44 regressive X-ray patterns were verifiable in this group. The idiopathic pulmonary fibrosis as final diagnosis only in 18/44 (41%) cases were established. Further diagnostic procedures are needed if the clinical data, the results of HRCT and histological examinations are not in correlation.

[Non-malignant cells in pleural fluid].

Insufficient attention has been paid to the cytological examination of cellular elements of the pleural fluid besides or in the absence of tumour cells. 108 cases studied due to pleural fluid were selected. They were characterized by the following: 1. each had histological diagnosis established by either pleuroscopy or by pleural needle biopsy and 2. neither of the samples contained tumour cells. Relationship of the dominant cell type and the ethiology of the pleural fluid was analysed. In case of punctates rich in lymphocytes further cytopathological differentiation is possible, e.g. in case of tuberculotic origin the absence of large mesothelial cells with Giemsa-basophilic cytoplasm is rather characteristic. The use of bioptic methods in the clarification of the origin of pleural fluid is still indispensible.

In vitro complement activation by ragweed allergen extract in the sera of ragweed allergic and non-allergic persons.

Ragweed allergen (RWA)-induced complement activation in sera of 40 RW allergic patients and of 40 non-allergic controls was investigated. After treatment of the sera with RWA, levels of C3a, C5a, C3bBbP, C1rC1sClinh, SC5b-9 and granulocyte-aggregating activity were determined. Concentration of RW-specific IgG was also measured. After RWA treatment dose-dependent complement activation was detected in sera of RW allergic and non-allergic persons. C3a generation was observed mostly in the sera of RW allergic individuals, while levels of C3bBbP and of RW-specific IgG were significantly higher in sera of allergics, and a strong correlation was found between these two parameters. In a prospective clinical study, a significant positive correlation was observed between the extent of RWA-induced alternative pathway (AP) activation and the severity of symptoms of allergic rhinoconjunctivitis that were developed in a 4-week period subsequent to blood sampling. These observations suggest that complement activation has a role in the development of the symptoms of RW allergy.

Longitudinal lung function study in heterozygous PiMZ phenotype subjects.

It is a matter of controversy whether subjects who are heterozygous (PiMZ) for alpha 1-antitrypsin deficiency are at risk of developing pulmonary emphysema. To assess the role of MZ phenotype in the development of abnormal lung function the authors performed a 10 year follow-up study of 28 PiMZ subjects, compared to 28 matched-paired normal PiMM subjects. Maximal expiratory flows and mechanical properties of the lungs were studied, in order to determine the changes of the lung function parameters characteristic of pulmonary emphysema. Total lung capacity and residual volume increased, whereas forced expiratory volume in one second, expiratory flows, diffusing capacity of the lungs for carbon monoxide, and static transpulmonary pressures decreased in the PiMZ patients. The majority of the controlled functional parameters were found to deteriorate significantly in PiMZ patients during the 10 year period. Trypsin inhibitory capacity in the PiMZ group (mean +/- SD) was 0.65 +/- 0.17 mg.ml-1 as compared to 1.52 +/- 0.3 mg.ml-1 in the PiMM group. These changes exceeded the values expected as physiological changes due to ageing. The findings in the present longitudinal study--especially the decrease in elasticity, which is the primary pathophysiological damage in alpha 1-antitrypsin deficiency--support the concept that the PiMZ phenotype is a risk factor for the development of pulmonary emphysema at younger age than in those without the deficiency.

[Needle biopsy of the pleura].

A total of 171 pleural needle biopsies were carried out in 123 patients with pleural effusion. The sensitivity of the method proved to be 51% for malignant diseases and 75% for tuberculotic pleurisy, respectively. Performing biopsy simultaneously with the cytological examination of the pleural fluid, malignancy was proved only by needle biopsy in 20% of the patients, while cytology was found negative in these cases. Simultaneously performed thoracocentesis and pleural needle biopsy is suggested.

[Late post-tracheostomy airway complications in patients with central nervous system injuries].

At decannulation or often weeks later some of the patients undergone long-term mechanical ventilation through tracheostoma reveal symptoms of airway stenosis. Posttracheostomy airway complications detected during the rehabilitation of 34 patients with central nervous system injury are presented. Endoscopic examinations (total 130) were performed with Olympus BF B3 and OES 20-type fiberscopes and Friedel-type rigid bronchoscopes under local or general anaesthesia. Stridor (20 cases) and possible decannulation (10 cases) were the main indications of the first endoscopic examinations. Stridor was caused by tracheal (12 cases) and laryngeal (8 cases) stenosis. With six patients decannulation was possible after the first endoscopy. Removal of granulomas and sutures was successful in 8 cases. Rigid bronchoscopic dilatations were temporarily successful in 7 cases, but in five of them it had to be repeated on emergency. Further therapeutic interventions were: recannulation (3 cases), retracheostomy (4 cases), implantation of silicon T-endoprothesis (5 cases), tracheal resection (4 cases). Three patients are discussed in details. Eliminating airway complications largely contributed to rehabilitation of the nervous and musculoskeletal system, improved the quality of life, and in acute cases it was a life-saving measure. In order to prevent the development of late airway complications or detect them in time, it is recommended to have an endoscopic protocol following every tracheostomy: 1. at the time of decannulation 2. at closing the trachea and 3. 2-3 months after decannulation.

Use of Taleum 1-mg inhalation aerosol in bronchial asthma patients.

The effect of 2 sodium chromoglycate products: Taleum 1-mg aerosol (EGIS) and Intal powder capsule (Fisons) has been examined for 4-4 weeks in 15 extrinsic asthma patients by cross-over self-controlled open method. The patients measured peak expiratory flow (PEF) 5 times daily and recorded the time of dyspneic periods in a diary as well as the amount of bronchodilator spray (Berodual, Boehringer) used as adjuvant therapy during dyspnea. The results of the weekly evaluation of the complaints and PEF values proved that both drugs are similarly effective in the prevention of dyspnea caused by bronchial asthma. The adjuvant inhalation betamimetic and anticholinergic drug requirement was lowered, the number, intensity and total time of dyspneic episodes decreased. In the course of the examinations Taleum 1-mg inhalation aerosol proved to be of identical value with Intal powder capsule. Some patients who do not like powder inhalation found the Taleum aerosol drug form to be more advantageous. Side-effect of drug was not observed.

Loderix (setastine) tablets in the treatment of allergic rhinoconjunctivitis.

The effect of a 3-week treatment with Loderix is examined in an open study in 40 patients suffering from allergic rhinoconjunctivitis. Side-effects, mainly sleepiness, fatigue, weakness, were observed in nearly half of the patients. These were, in general, mild and of a transient character. Treatment had to be stopped in 2 patients due to developed adverse effects. Safety parameters as blood picture, liver function tests, renal function parameters showed no alterations during the study course. During the treatment periods rhinoconjunctivitis symptoms disappeared or significantly decreased in 22 patients out of 40. Moderate effect was registered in 14 patients, and treatment was ineffective in 4 cases. In 6 patients the doses were doubled from the 2nd week of treatment causing an increase in effectivity without a change in side-effect profile.

Hyperaldosteronism in the sodium depleted rat: effect of a low sodium diet or diuretic treatment on steroid output by the superfused adrenal zona glomerulosa.

The effect of chronic and acute sodium depletion on the function of the adrenal zona glomerulosa was examined by means of superfusion of adrenal capsular glands. The glands were removed from rats kept on a low sodium diet for 7 days or from dexamethasone-pretreated rats 30 min after administration of the diuretic drug furosemide. Chronic sodium depletion brought about a high initial output of aldosterone followed by a rapid fall in output. The initial rate of corticosterone output did not differ significantly from that by control glands but exhibited a more rapid decline with time. Aldosterone: corticosterone ratio, an indicator of the rate of conversion of corticosterone to aldosterone, was much higher in the sodium depleted group throughout the whole superfusion period. Acute sodium depletion was followed by high initial and rapidly falling aldosterone and corticosterone output, without any significant change in the ratio of aldosterone to corticosterone output rate. The above dynamic patterns of steroid output indicate that a sodium deficient diet evokes hyperaldosteronism by increasing the formation of aldosterone from corticosterone (not excluding the possibility of increasing the formation of corticosterone as well) while diuretic treatment stimulates aldosterone secretion by acting on the formation of corticosterone only.
