RESUMEN

Helminth infections caused by Enterobius vermicularis have a cosmopolitan character and most often affect the paediatric pre-school and school age population. The presented study was conducted to determine the prevalence of E. vermicularis in the analyzed population of children in the Eastern Slovakia. The Graham's scotch tape method was used to investigate the presence of Enterobius vermicularis eggs in 390 specimens. The analyzed set consisted of 218 girls and 172 boys, divided by age into three groups - aged from 5 months to 2 years, aged from 3 to 6 years, and aged from 7 to 15 years. Investigation of perianal scotch tapes of children for the presence of E. vermicularis eggs revealed the prevalence of E. vermicularis was P = 3.59 %. Depending on the incidence of E. vermicularis infection, we detected no statistically significant difference (p> 0.05). The prevalence of E. vermicularis in boys was P = 4.07 %, and in girls P = 3.21 %. The highest prevalence of E. vermicularis was recorded in the group of children aged from 3 to 6 years (P = 5.03 %). Most of the samples were positive at age 4 and 5. The lowest prevalence was in the group of children aged from 5 months to 2 years (P = 0.97 %), and the prevalence of E. vermicularis in the group of children aged from 7 to 15 was P = 3.91 %. The difference in the incidence of E. vermicularis infection among different age groups of children was not statistically significant (p> 0.05). Enterobius vermicularis nematode infection and enterobiasis currently represents a major public health problem in Slovakia. At the present its occurrence is the most frequent in the paediatric population. Therefore it is important to introduce a targeted hygienic-epidemiological measure in children's collectives, what also should include proper and effective diagnostics and frequent recurrent therapy.

RESUMEN

BACKGROUND: Acute stress in patients experiencing cancer diagnosis and the post-traumatic stress disorder in cancer survivors results in impaired overall quality of life mainly due to associated psychological and physical alterations, including anxiety, depression, sleep disturbances, cognitive dysfunctions, fatigue, pain, cachexia and others. Recent studies revealed a new insight into molecular mechanisms contributing to the development of cancer-related co morbidities. It has been shown that adverse psychosomatic reactions including cancer depression to emotional cancer distress result from neuroendocrinne dysfunctions, disruption of the hypothalamus- pituitary-adrenal axis and sympathetic nervous system, serotonin-dopamine interactions and circadian sleep- wake rhythm disruption. AIM: The aim of the present study was to evaluate clinical studies oriented toward elucidation of the hypothesis that cancer-related anxio- depressive syndrome is the major disorder leading to the development of accompanying psychosomatic disruptions. MATERIAL AND METHODS: The data of the biopsychosocial approach in the treatment of cancer presented in the current literature were collecting using appropriate electronic databases and were elaborated in the form of meta-analysis of 24 selected publications. RESULTS: According to relevant clinical studies, psychosocial interventions and psychopharmacological treatment has been shown to reduce cancer symptomatology and to improve the ability of patients to cope with the disease. Thus, one of the key pillars of supportive care in oncology is stress reduction. Cognitive- behavioral interventions and group psychosocial therapies have shown to reduce stress from the diagnosis and treatment, to palliate depression and to help in restoring the circadian rhythm. Psychopharamacological interventions are the most useful approaches in the reduction of stress-induced cancer comorbidities. In the presented study, a plausible role of stress reduction in the protection of cancer patients from posttraumatic and anxio- depressive syndrome, physical and psychical suffering, from decrease of patients quality of life, ability to cope with the disease and cooperate in cancer treatment has been analyzed. CONCLUSION: Implementation of the biopsychosocial model of cancer care needs further cooperation between behavioral scientists and clinical oncologists attempted to elucidate further possibilities of psychosocial and pharmacological interventions leading to the regulation of stress-induced alterations of the neurotransmitter system and neuroendocrinne dysfunctions reduction of cancer-related co morbidities and improvement of patients survival time.

RESUMEN

OBJECTIVE: To assess psychosocial support needs among Slovak breast cancer survivors treated by breast conserving surgery. METHODS: Patients responded the EORTC QLQ 30.3 questionnaire and the self-elaborated BCPN (Breast Cancer Psychosocial Needs) questionnaire one and three years after breast conserving surgery (BSC) and modified radical mastectomy (MRM). RESULTS: Assessment of psychosocial distress related to breast cancer treatment have shown a remarkable time-related increase in scores of emotional distress symptoms among breast cancer patients treated with breast-conserving surgery. Analysis of psychosocial support needs of these patients has shown, that a substantial part of breast cancer survivors are feeling inadequate beneficial psychosocial support from health care providers (informational support), social oncology workers, and psychologists (emotional support). Insufficient targeted psychosocial support involved individual as well as group intervention (provided by breast cancer patients surviving the disease for long time). CONCLUSION: Unmet psychosocial needs from health care providers has been perceived as a major factor harming patients ability to cope with the disease and to maintain their family, marital and social functioning (Tab. 2, Fig. 1, Ref. 22).

RESUMEN

From the second semester of 2002 to the end of the first semester of 2005, a total of 2544 bacterial strains were isolated from the blood stream of patients with clinical sepsis and bacteremia hospitalized in six University Hospitals in the Slovak Republic. Almost 30% of strains were coagulase-negative staphylococci (CONS), about 14% were Staphylococcus aureus and, of the Gram-negative bacteria, up to 9% were Klebsiella pneumoniae. All CONS, S. aureus and Enterococcus spp. strains were found to be still susceptible to vancomycin, but the resistance of CONS and/or S. aureus to macrolides and fluoroquinolones dramatically increased during the period of this study. Among Gram-negative bacteria, increasing levels of resistance to higher generation cephalosporins, to fluoroquinolones resistance in Pseudomonas aeruginosa and Acinetobacter spp. to meropenem was recorded, which is alarming. The results were periodically submitted to cooperating hospitals with proposals for rationalizing the prophylactic and general use of indicated antibiotics as well as for improving hospital hygiene measures and anti-epidemic practices.

RESUMEN

The aim of this study was to assess trends in risk factors, etiology, outcome and treatment strategies for endocarditis over 23 years in Slovakia. A prospective survey of 606 cases of infective endocarditis (IE) was conducted from 1984-2006. Rheumatic fever as well as previous dental surgery showed decreasing trends within the last 23 years. Also embolic complications of IE declined along with increasing rates of surgically treated patients. No significant changes in etiology were detected apart from the fact that culture-negative endocarditis increased from 10.7% to 55.4% between 1998-2001. Surgically treated patients increased from 22.7% (1984-1990) to 50.1% (2002-2006) and mortality dramatically decreased from 26.7% (1984-1990) to 5.3% (2002-2006). Staphylococcus aureus and coagulase-negative staphylococci were the leading causes (22.4% - 48%) followed by viridans streptococci (12.2%-18.2%) were a relatively stable trend over 23 years of IE in Slovakia.

RESUMEN

Whole-life consumption of the pure Tokaj wine (The Furmint variety) with documented antioxidative activity significantly elongated (p<0.05) the life of laboratory animals in comparison to the control group consuming water and in comparison to group consuming ethanol (10%). Whole-life intake of ethanol (10%) diluted with water neither shortened nor elongated life of laboratory animals in comparison to control group consuming water. An increased dosing of the Tokaj wine combined with water shortened life expectation (p<0.001). Obviously mixing of wine and water increases the absorption of toxic elements influenced by an acid medium through the change of anions to cations, but also increased appetite resulting into obesity on the basis of hyperphagia.

RESUMEN

We investigated regularly swabs of adults dispenzarised at Mary Immaculate Clinic of Trnava University in Nairobi providing free health care for about 50 000 population of Mukuru Slums. 20 patients who were treated for AIDS by our clinic (those who started HAART before Free National AIDS Cooperation Programme - NASCOP) were assessed after 1, 2 and 3 years (18 of 20 completed the survey, other 2 loss of follow up, probably died. Exposure to other molecules can select resistant mutants. Previous exposure to TMP/SMX was similar in both groups and therefore was not responsible for the difference between resistance patterns.

RESUMEN

Within a cohort of 606 cases of infective endocarditis, 263 were complicated and 99 embolizing, of them 32 to the central nervous system (CNS). Significant predictors of CNS embolisation were inappropriate therapy (p<0.01) and enterococcal etiology (p<0.01). Mortality in patients with CNS emboli was 65% what was significantly higher than in cases without embolisation - 15% (p<0.01).

RESUMEN

The aim of this study was to assess mortality and sequellae within cases from Nationwide survey of community acquired meningitis and identify risk factors for inferior outcome. Risk factors such as underlying disease (diabetes mellitus, cancer, trauma, neonatal age, splenectomy, alcoholism, sepsis, other infections), etiology, clinical symptoms and outcome (death, improvement and cured after modifications of ATB therapy, cured without change of therapy, cured with neurologic sequellae) were recorded and analysed with univariate analysis (chi2 or t test for trends, CDC Atlanta 2004). Analysing risk factors for inferior outcome (death or cured with neurologic sequellae), we compared patients who died or survived with neurologic sequellae to all patients with community acquired bacterial meningitis. Univariate analysis showed that trauma (p<0.05), alcohol abuse (p<0.05), diabetes, S. aureus (p<0.05) and gram-negative etiology (A. baumannii, Ps. aeruginosa or Enterobacteriaceae) (36% vs. 11,9%, p<0.05) were predicting inferior outcome. Analysing risk factors for treatment failure (death or failed but cured after change of antibiotic treatment) prior sepsis (34.1% vs. 13.9%, p<0.01) and gram-negative etiology (25% vs. 11.9%, p<0.02) were statistically significant predictors of treatment failure. Neisseria meningitis had less failures (p<0.05). Concerning infection associated mortality again diabetes mellitus (p<0.05), alcoholism (p<0.05) staphylococcal and gram-negative etiology (p<0.05) were significant predictors of death. N. meningitis had surprisingly less treatment failures (appropriate and rapid initial therapy). Neurologic sequellae were more common in patients with alcohol abuse (p<0.05), craniocerbral trauma (p<0.05) and less common in meningitis with pneumococcal etiology (p<0.05).

RESUMEN

Documentation of the anterior segment and the eye fundus with instruments that enable quality precision diagnostics is a common and important part of screening in humanitarian ophthalmology projects. It is the essential element in diagnosis, monitoring and management of eye diseases. In sub saharan countries within the screening for ophthalmologist are not available the modern technologies such as biomicroscope (slit lamp) or fundus camera. We describe our experience with photographs of anterior segment of the eye by using digital camera and Smartphone. The documentation of the eye fundus was recorded through 20D Volk spherical lens to Smartphone. MATERIAL AND METHODS: Within the screening projects in collaboration with St. Elisabeth University of Health and Social Sciences for eye diseases in the year 2014 in Bigugu, Rwanda and in 2015 in Mapuordit, South Sudan, we examined patients who were unable to reach ophthalmologic care. We used a flashlight, a direct ophthalmoscope, tables to determine visual acuity on illiterate, Schiøtz tonometer, Volk lens, Smartphone. Patients who underwent screening, and needed glasses, got from humanitarian collection already used dioptric eyeglasses or sunglasses. For documentation of the anterior segment we used a digital camera and for patients in whom it was necessary to document fundus findings detected by direct ophthalmoscopy we took the opportunity of Smartphone with 8 Mpix camera and the LED flash and Volk lens plus 20 Diopters. RESULTS: In 2014 within the project in Bigugu, Rwanda and in 2015 in Mapuordit, South Sudan, we examined patients in an improvised clinic without access to electricity.We examined in 2014 a total of 340 patients and in 2015 a total of 290 patients. Patient age was due to the unavailability of designated identification records estimated with the help of an interpreter. In both groups, the mean age of the patients was about 30 years. The most common diseases leading to blindness were cataract, trachoma, post-traumatic conditions. Infectious diseases and consequences of untreated infectious diseases were the cause of 20% of the permanent changes on the surface of the eye or the adnexa. In the group of HIV positive patients we did not mention pathological findings on the eye fundus. CONCLUSION: Anterior segment findings documentation with digital camera or mobile phone and fundus examination using a Smartphone and Volks lens with a value of plus 20D is inexpensive and manageable technique which can capture high quality and reproducible images. These techniques are suitable for photo documentation of anterior segment and also eye fundus screening within humanitarian projects of eye diseases in developing countries. KEY WORDS: anterior segment examination, eye fundus examination, Smartphone, digital camera, humanitarian screening projects of eye diseases.

RESUMEN

Risk factors, mortality and antimicrobial susceptibility of Pseudomonas aeruginosa bacteremias isolated from 148 patients from all University Hospitals in Slovakia were analyzed. Only 1.2% of 169 strains of P. aeruginosa were resistant to meropenem, 4.1% to piperacillin/tazobactam, 7.7% to ceftazidime as well as cefepime and 12% to amikacin. More than 30% of P. aeruginosa were resistant to ciprofloxacin. Our analysis of risk factors for antimicrobial resistance to the particular antimicrobials, indicated no difference in risk factors and outcome in cases infected with P. aeruginosa bacteremias resistant to amikacin, piperacillin/tazobactam or ceftazidime in comparison to episodes caused by P. aeruginosa due to susceptible isolates. When comparing risk factors for P. aeruginosa bacteremia in children vs. adults, cancer vs. non-cancer patients, several differences in risk factors were observed. Neither antimicrobial resistance to amikacin, ceftazidime or piperacillin/tazobactam, nor appropriateness of therapy according to two separate analyses were associated with better outcome.

RESUMEN

Oropharyngeal candidiasis is a frequent infection in cancer patients who receive cytotoxic drugs. In this study, the efficacy, safety and tolerance of fluconazole and itraconazole were compared in non-neutropenic cancer patients with oropharyngeal candidiasis. Of 279 patients who were randomised between the two treatment groups, 252 patients were considered to be eligible (126 in each group). The clinical cure rate was 74% for fluconazole and 62% for itraconazole (P=0.04, 95% Confidence Interval (CI): 0.5-23.3%). The mycological cure rate was 80% for fluconazole and 68% for itraconazole (P=0.03, 95% CI: 1.2-22.6%). The safety and tolerance profile of both drugs were comparable. This study has shown that in patients with cancer and oropharyngeal candidiasis, fluconazole has a significantly better clinical and mycological cure rate compared with itraconazole.

RESUMEN

Quinolones are valuable antimicrobial agents for prevention and therapy of febrile neutropenia. However, as with other groups of antibacterials, there are limitations to the use of quinolones in immunocompromised hosts: they should not be used in those neutropenic patients receiving ciprofloxacin or ofloxacin for prophylaxis, because of the risk of infection with resistant Gram-negative, or less susceptible Gram-positive, organisms. There are also insufficient data to support monotherapy of febrile neutropenia with quinolones, although some studies using higher ciprofloxacin dosages have reported encouraging results. More data on this issue, including use in paediatric cancer patients, are required. Quinolones are indicated for empirical therapy in combination with agents active against Gram-positive organisms, such as broad spectrum penicillins with or without beta-lactamase inhibitors, or in combination with vancomycin or teicoplanin. Some studies have shown that a combination of cefotaxime or ceftriaxone may provide better coverage against streptococci, but there are insufficient data on the combination of quinolones with third generation cephalosporins. A specific group of patients with low risk mild to moderate neutropenia with solid tumours may benefit from oral therapy with quinolones in combination with either an aminopenicillin with a beta-lactamase inhibitor or clindamycin. After 10 years of quinolone use in febrile neutropenia, these agents can still be regarded as valuable drugs of choice; however, the incidence of resistance among staphylococci and Pseudomonas spp., especially in centres using quinolones as prophylaxis, is increasing.

RESUMEN

PURPOSE OF THE STUDY: To assess efficacy and safety of fluconazole in neonates with Candida fungemia. STUDY DESIGN: Multicenter prospective protocol of all fungemias appearing between January 1, 1993, and December 31, 1997, in four major university hospitals. RESULTS: Forty neonates, 28 of them with very low birth weight (<1500 g; 30.5 median gestation week), with documented Candida albicans fungemia were treated with intravenous fluconazole in a daily dosage of 6 mg/kg once daily for 6 to 48 days. Thirty-four received fluconazole as monotherapy and 6 received it in combination with amphotericin B. Thirty-two (80%) were cured; 4 of them relapsed despite at least 14 days of therapy, but they were ultimately cured without sequelae. Eight other neonates died, 4 because of fungal infection and 4 because of prematurity or hemorrhage or lung failure, with fungemia (20% overall and 10% attributable mortality). Two neonates had elevated liver enzymes during fluconazole therapy and 2 others had elevated serum creatinine during fluconazole monotherapy. In none of them did these abnormalities necessitate discontinuation of antifungal therapy. In 8 neonates fungal meningitis developed as a complication of fungemia. All but 3 fungemias were C. albicans; 3 were Candida parapsilosis. CONCLUSIONS: Fluconazole was safe and effective antifungal therapy even in complicated or Candida fungemia in neonates and in infants with very low birth weight.

RESUMEN

From 1989 until 1996, during the last 8 years, the proportion of Candida (C.) krusei, and other non-albicans Candida spp. isolated from surveillance cultures and from sterile body sites, was analyzed among 13,758 admissions in a National Cancer Institute. During these admissions a total of 9,042 isolates were prospectively collected from surveillance cultures, and 126 from blood cultures. The proportion of C. krusei among all organisms was 12.7% to 16.5% in 1989 through 1991, i.e., before fluconazole was introduced into prophylactic protocols. After the introduction of fluconazole into prophylaxis in acute leukemia in 1992 the incidence of C. krusei was 7.9% to 8.6% during 1994 to 1996. After 5 years of using this drug for prophylaxis, the incidence of C. krusei was lower than before this drug was introduced in our institute. Among yeasts, the most frequently isolated pathogen was still Candida albicans (72.2% of all isolated fungal organisms). Among molds, Aspergillus spp. was the most frequently isolated agent. Analyzing the etiology of proven fungal infections (fungemias) confirmed by positive blood cultures, C. albicans was the most common causative organism in 53.8% of cases. The incidence of fungemia due to Torulopsis (C.) glabrata and C. krusei before and after fluconazole introduction did not change. Of 126 organisms isolated from blood cultures, there was no increase in T. (C.) glabrata or C. krusei after introduction of fluconazole for prophylaxis and therapy, and the quoted 6.4% of fungemic episodes remained stable with an incidence of 1 fungemia/year since 1991. The proportion of C. krusei and C. glabrata among Candida spp. was decreasing in our center between 1989 and 1996. Also, the proportion of non-albicans Candida spp. among isolates decreased from 25.7% in 1990 to 11.9% in 1996.

RESUMEN

A 10-year prospective survey of fungaemia in the Slovak Republic, involving 31 microbiology laboratories and 71 hospitals, was conducted from 1989-1998 (10 years): 310 fungaemias were analyzed for etiology, clinical characteristics, therapy, and outcome. C. albicans was responsible for 191 (61.6%) fungaemias, non-albicans Candida spp. (NAC) for 97 (31.3%), non-Candida yeasts for 18 (5.8%) and moulds (Fulsarium spp.) for four fungaemias. The most frequent NAC isolated from blood cultures were C. parapsilosis--30 (9.7%), C. krusei--18 (5.8%), C. tropicalis--14 (4.5%), and C. glabrata--10 (3.2%). Secular trends in etiology showed a sustaining decrease of C. albicans (from 100% in 1989 to 50.7% in 1998) and increase of NAC (from 0% in 1989-1990 to 46.3% in 1998). Non-Candida yeasts and moulds showed a stable proportion during the investigated period. There were statistically significant differences in etiology of fungaemia various subgroups of patients: non-albicans Candida spp. was significantly more frequent observed among subgroups of patients with pancreatitis and coma (53.3% vs. 31.3%, p < or = 0.02) and less frequently in the subgroup of neonates (15.0% vs. 31.3%, p < or = 0.006). Vice versa, C. albicans appeared more frequently in neonates (85%).

RESUMEN

Stenotrophomonas maltophilia (298/85) was isolated from the extensively inflamed conjunctiva of a neonate in a regional hospital in Ostrava, Czech Republic. It was resistant to all available antibiotics except cefepime and trimethoprim. The donor S. maltophilia strain 298/85 transferred carbenicillin and cephaloridine resistance determinants to recipient strains of Escherichia coli K-12 3110 rif+ and Proteus mirabilis P-38 rif+. All transconjugant colonies were co-resistant also to kanamycin, cefotaxime, and aztreonam. Active hydrolysis of imipenem in the original strain was inhibited by ethylene diamine tetra-acetic acid, and hydrolysis of cefotaxime and aztreonam in the original strain and in the E. coli K-12 transconjugant was inhibited by clavulanate. In contrast, ceftazidime was hydrolyzed by the original strain and was not inhibited by clavulanate, indicating a different character of the resistance to cefotaxime or aztreonam and ceftazidime.
