[Myocardial infarction in the young - our results and experience]. / Infarkt myokardu v mladom veku - nase výsledky a skúsenosti.

AIMS: Coronary artery disease in young adults is important task of contemporary cardiology. Presented our results experience and opinion were obtained by our long term investigation of myocardial infarction in young patients under 40 years. METHODS: Two sets of patients were examined - 78 patients (74 men, 4 women) hospitalised in pretrombolytic era in prospective 8 years follow up (1984-1992) and 39 patients (35 men, 4 women) admitted during period 2000-2010 analysed retrospective. RESULTS: Myocardial infarction in young age belongs roughly to two different groups with considerable overlap in pathogenetic mechanisms: 1. angiographycally normal coronary arteries or unilocular nonsignificant atherosclerotic stenosis (less 50%) in 25-30% with thrombotic occlusion of one infarct related artery probably with substantial vasospastic component. Patients were younger (average 31.7 ± 3.7 years), dominant risk factors smoking, hyperlipidemia, excessive physical and emotional stress. Disease course and prognosis are favourable. 2. premature accelerated atherosclerosis with significant (more 50%) in 70-75 % often multivessel affection. Pts were significantly older (average 35.8 ± 2.6 years; < 0.001) bad risk factors profile, worse clinical course and poor long-term prognosis. CONCLUSIONS: Study of myocardial infarction in young adults indicates: great role of risk factors, mainly smoking, hyperlipidemia, family history and type A behaviour, hostility with participation of low education level and social inequality (unemployment). Noticeable are hypercoagulable states and trauma. Dominancy of men (90-95%). Prognosis depends on age, extend of coronary atherosclerosis and residual cardiac function. Disease picture has not been changed during last 30 years. Aggressive control over risk factors is unavoidable. Current requirement is to evaluate impact of modern treatment strategy on long-term survival. Key words: coronary artery disease - myocardial infarction at young age.

Expression pattern of anti-apoptotic protein survivin in dysplastic nevi.

UNLABELLED: The anti-apoptotic protein survivin was detected in a panel of 27 dysplastic nevi. From each representative paraffin block 4 mm sections were cut and stained with anti-survivin antibody (DAKO, Clone 12C4). In each section, the labeling intensity, the subcellular location of survivin antigen, the percentage of labeled cells and the degree of dysplasia were assessed. Survivin was present in 23 out of 27 cases (85.2%), but absent in 4/27 cases (14.8%). Positive staining was confined to the cytoplasm (C) of nevus cells only in 18 cases (66.7%), while cytoplasmic as well as nuclear positivity (NC) was found in 5 cases (18.5%). In no case solely nuclear staining could be seen. Furthermore, in 4 out of 5 cases (80%) with NC staining, severe dysplasia was found. Our data point at usefulness of survivin staining, otherwise rarely performed in dysplastic nevi. We confirm the importance of nuclear location of the survivin antigen, which may be helpful for assessing the possible progression to melanoma. KEYWORDS: survivin, immunohistochemistry, nevi, dysplasia, melanoma.

Effects of Mg-ATP on the flavonoid production in the Scutellaria baicalensis Georgii suspension cultures.

This work focused on the cultivation of S. baicalensis Georgii in vitro cultures and on the possibilities of increasing the production of secondary metabolites in these cultures. The aim of the Sstudy was to determine whether the baicalin transport through vacuolar membrane is dependent on the presence of Mg-ATP. Our results showed that Mg-ATP had a significant effect on the ratio of baicalin and baicalein content and on the transport speed of these flavonoids. Therefore, the transport mechanism for baicalin are probably some of the MRP proteins which are the subfamily of the ABC transporte

Multiple cutaneous metastases as the first sign of lung cancer in a patient with well-differentiated papillary transitional cell carcinoma of the urinary bladder.

A case of multiple, cutaneous metastases as the first sign of lung cancer in a patient with well-differentiated, papillary, transitional cell carcinoma of the urinary bladder is presented. In the left clavicular region were two, sharply demarcated, dark red tumors measuring 3 and 2 cm in diameter with a history of rapid growth and intermittent spontaneous bleeding. Thorough examination of the patient revealed 16 additional skin lesions, which were dark red macules and papules, 2-3 mm in diameter, situated on the left side of the chest. The skin biopsy material (tumors, macular and papular lesions) was studied using histological and immunohistochemical techniques and showed intact epidermis and massive dermal and subcutaneous metastatic involvement by a small cell carcinoma with neuroendocrine differentiation most likely originating in the lung.

Salicylate intoxication after use of topical salicylic acid ointment by a patient with psoriasis.

The authors describe a therapeutically well managed case of severe salicylate intoxication in a patient with psoriasis who treated himself with 40 percent salicylic ointment applied to approximately 41 percent of his body surface. Nineteen hours after the application of salicylic acid, his blood level of the agent was 6.04 mmol/liter. The patient underwent hemodialysis and was discharged after fourteen days in good general health.

Squamous cell carcinoma of the penis. Analysis of 24 cases.

The authors evaluated retrospectively 24 cases of spinocellular carcinoma of the penis, trying to detect aetiological carcinogenic factors of the disease. Phimosis persisting since childhood was reported by ten men, whereby in five of them circumcision was performed during puberty. The duration of symptoms up to the time of biopsy and histological verification of differentiated spinocellular carcinoma of the penis varied from one month to thirteen years. Eight patients (33.3%) belonged to category T1, 8 (33.3%) to T2 and 8 (33.3%) to T3. Fifteen tumours (62.5%) were G1, 5 (20.8%) G2 and 4 (16.7%) G3. In 5 men print cytology was negative.

A study of possible causal relations between squamous cell carcinoma of the penis and carcinoma of the cervix uteri.

The authors investigated 26 regular sexual female partners of 24 men with squamous cell carcinoma of the penis. Neoplasms were diagnosed in 6 (23.1%) of the total of 26 women. STDs were found in 6 (23.1%) women. In 2 the cytologic findings on the cervix were classified as PAP III (PAP IIIa-CIN I, PAP IIIb-CIN III). Squamous cell carcinoma of the uterine cervix was found in 2 women (1 case PAP IV-CIN III; 1 case PAP V-suggestive of invasive carcinoma). Endometrial adenoacanthoma, mammary adenocarcinoma, squamous cell carcinoma of the right hand and non-Hodgkin's malignant lymphoma (centroblastic) were found in 1 case each.

Isolation of Neisseria gonorrheae and concomitant bacterial microflora from urine obtained by suprapubic bladder puncture in women with gonococcal urethritis.

The authors examined 38 non-pregnant women with gonococcal urethritis. Thirty-three (86.8%) of them suffered also from endocervical gonorrhea. Neisseria gonorrheae (N. go) was isolated from the midstream of urine in a quantity of 1 x 10(2) to 9 x 10(8) in 1 ml of urine with an average of 5.08 x 10(4) N. go per 1 ml of urine and S. E. M. +/- 3.85 x 10(4) N. go per 1 ml of urine. On the basis of suprapubic puncture ascendent propagation of bacteria to the bladder was observed by cultivation in 13 (34.2%) patients, with isolation of N. go in 5 cases.

[The effect of amniotic fluid on Neisseria gonorrhoeae]. / Effet du liquide amniotique sur Neisseria gonorrhoeae.

This study shows the antibacterial effect of amniotic fluid collected on 10 women from 32 to 38 weeks. Two techniques were used. The first is a quantitative analysis of a bacterial culture with amniotic fluid as compared to controls, with inhibition by the amniotic fluid demonstrated. The second is a morphologic analysis of gonorrheal cultures by electron microscopy, showing alteration of the bacteria when amniotic fluid is present. These facts are of interest when one tries to understand the discrepancy between high rates of discovery of bacteria during pregnancy and low rates of intra-amniotic infection by Neisseria gonorrhoeae.

[Quantification of Neisseria gonorrhoeae from the cervicovaginal area in nonpregnant women infected with gonorrhoea]. / Kvantifikácia Neisseria gonorrhoeae z cervikovaginálnej oblasti negravidných zien infikovaných kvapavkou.

The authors studied quantification of Neisseria gonorrhoeae from the cervicovaginal area of 53 nonpregnant women with gonorrhoea. The variability of the amount of gonococci in cervicovaginal secretion was rather high from 1.0.10(1) to 1.1.10(8) cfu N. gonorrhoeae in 1 ml. Maximum values of N. gonorrhoeae have been found intra menses (from 1.0.10(2) to 3.0.10(8) cfu N. gonorrhoeae in 1 ml). These findings allow the authors to make some, already more or less known, conclusions usable in clinical practice.

[Study of malignant melanoma using 1H-nuclear magnetic resonance spectroscopy]. / Stúdium malígneho melanómu 1H-spektroskopiou nukleánej magnetickej rezonancie.

1H-nuclear magnetic resonance spectroscopy was used to study malignant melanoma extract. The aim of this work was to study low molecular weight metabolites soluble in water, which can be helpful for a more detailed understanding of tumor metabolism with a view to using this knowledge for diagnosis. The authors found in a well distinguished spectrum the presence of numerous low molecular weight metabolites such as glutamate, glutamine, choline, inositol, creatine, phosphocreatine, phosphocholine, glucose, acetate, alanine, lactate. It is necessary to correlate these in-vitro findings with a study of the above mentioned metabolites in-vivo. Malignant melanoma is appropriate for this investigative and diagnostic technique because of its superficial localization. (Fig. 1, Ref. 18.)

[Morphologic study of mastocytes from skin biopsies in patients with non-systemic and systemic mastocytosis]. / Morfologická stúdia mastocytov z kozných biopsií pacientov s nesystémovou a systémovou mastocytózou.

The authors describe morphologic changes in mastocytes in the picture of transmission electron microscopy (TEM) and skin changes in patients with urticaria pigmentosa (7 causes) and systemic mastocytosis (2 causes). The presented study analyzes the changes in the cellular membrane and cytoplasmic processes, intracytoplasmic membrane structures, mitochondria, granules, and nuclei of mastocytes in patients with systemic mastocytosis. The authors evaluate these cells as being atypical, respectively immature. The study discusses the malignization of these states. (Tab. 2, Fig. 8, Ref. 16.)

[Treatment of chlamydia infections and a brief review of the problems]. / Liecba chlamýdiových infekcií a strucný prehl'ad problematiky.

The authors treated 35 patients (17 males, 18 females) with chlamydial infection of the urogenital system by means of azithromycin dosed 1.0 g for the first day, 500 mg from the second till the fifth day of treatment with 82.9% effectivity.

[Juvenile hyaline fibromatosis]. / Juvenilná hyalínová fibromatóza.

BACKGROUND: Juvenile hyaline fibromatosis is a sporadic hereditary disease with autosomal recessive mode of inheritance, characterized by the presence of nodules and tumours in the skin and soft tissues and gingival hyperplasia. The majority of patients are growth retarded, suffer from joint disorders, contractures, osteolytic lesions and have a positive family history. The disease most frequently occurs in children, but may be diagnosed also in adults. Since 1873, when the disease was described by Murray, only a few cases were introduced in the literature. THE AIM AND THE BASIS OF THE STUDY: To present the clinical pattern of a patient diagnosed at the age of 28 and describe also the histopathological, immunohistological and electron-microscopic findings of excisions from the lesions. METHODS: The pathologist in cooperation with clinicians from several disciplines established the diagnosis on the basis of typical histopathological picture and additional immunohistological tests not yet introduced in the literature. RESULTS: Tumorous lesions contained hyaline structureless matrix often with chondroid or even osteoid metaplasia, calcium salts. The matrix contained numerous fibroblastoid-like cells with eosinophilic cytoplasm, oval nucleus and often pericytoplasmic halo. ELMI investigation revealed dilated cisternae of rough endoplasmic reticulum and hypertrophic Golgi apparatus. Sporadically were particles with calcium salts density detected. Immunohistochemical tests revealed the expression of vimentin, alfa1-antitrypsin and alfa1-antichymotripsin by the tumorous cells. CONCLUSION: The authors presented an extremely sporadic childhood disease in an adult. The results are in accordance with the data from the literature. Immunohistochemical picture of "cementicles" has not yet been introduced in the available literature. (Fig. 12, Ref. 25.)

[Naftifin--laboratory and clinical experience with a new antimycotic from the allylamine group]. / Naftifin--laboratorní a klinické zkusenosti s novým antimykotikem ze skupiny alylaminu.

The authors evaluated the effectiveness of naftifin on a broad spectrum of 42 types of agents causing mycoses. Using the microdilution method, the authors assessed minimal inhibiting concentrations (MIC) of this antimycotic agent in 107 clinical isolates. Naftifin displayed a selective antifungal activity: excellent sensitivity was found in dermatophytes (MIC 90% = 0.39 mg.l-1), Aspergillae were medium sensitive (MIC = 0.09-12.5 mg.l-1). The majority of yeasts and filamentous fungi from the group of Zygomycetes was resistant to naftifin. The therapeutic results in 57 subjects with dermatomycoses corresponded to the results of in vitro tests of the antimycotic agent. Most successful as treatment of dermatophytoses at extra-intertriginous sites and treatment of pityriasis versicolor; manifestation of candidoses were not affected. The commercial preparation used--Fetimin cream--is considered by the authors a suitable alternative of hitherto used local antimycotics, in particular preparations from the azole series.

[Quantitative changes in CD4+ and CD8+ T-lymphocytes in the skin of patients with psoriasis treated with cyclosporin A]. / Numerické zmeny T-lymfocytov CD4+ a CD8+ v kozi psoriatikov liecených cyklosporínom A.

Many things are still not clear in the etiopathogenesis of psoriasis. Health workers in various branches of medicine and even those working in other professions linked with medicine can contribute to gaining more knowledge about its etiology, pathogenesis, diagnosis or treatment. This work presents results from observations of 19 patients with a severe form of psoriasis. Material for immunohistopathological examinations was taken from the margins of chronic psoriatic sites twice from each patient: before treatment and after a 4-week treatment by cyclosporin A. Numeric value of CD4+ T lymphocytes, CD8+ T lymphocytes, their ratios and the values of PASI score were followed. Significant decrease in CD4 T lymphocytes and slight decrease in CD8+ T lymphocytes where observed after treatment. The CD4+:CD8+ ratio dropped from the values of 2.10 to 1.68. A dramatic decrease in PASI score was observed--from the average value of 23.34 to the average value of 11.97. The authors compare and discuss the results of similar cytophotometric studies found in the works of other researchers, but this type of results (CD4+ and CD8+ T lymphocytes subpopulations) is very rare in available literature. The decreases found in all studied parametres correspond with clinically well-known treatment effect of cyclosporin A whose immunomodulating effect is targeted mainly at the T lymphocyte inflammatory population.
