Histopathological aspects and differential diagnosis of CD8 positive lymphomatoid papulosis.

Lymphomatoid papulosis (LyP) belongs to CD30+ lymphoproliferative disorders with indolent clinical course. Classic histological subtypes, A, B and C are characterized by the CD4+ phenotype, while CD8+ variants, most commonly classified as type D, were reported in recent years. We present 14 cases of CD8+ LyP. In all patients, self-resolving or treatment-sensitive papules were observed. Of 14 cases 7 produced results with typical microscopic features of LyP type D mimicking primary cutaneous aggressive epidermotropic CD8+ T-cell lymphoma. The infiltration pattern in 4 of 14 cases were consistent with classic LyP type B, without CD30 expression in two cases, resembling mycosis fungoides (MF). The morphology of 2 of 14 cases shared a certain consistency with classic type A and C, lacking eosinophils and neutrophils. Extensive folliculotropism characteristic to type F was observed in 1 of 14 case. Significant MUM1 and PD1 expression were detected in 2 of 14 and 3 of 14 cases, respectively. We concluded that CD8+ LyP may present with different histopathological features compared with type D, similar to CD4+ LyP variants. Differential diagnoses include CD8+ papular MF, folliculotropic MF and anaplastic large cell lymphoma in addition to primary cutaneous aggressive epidermotropic T-cell lymphoma. We emphasise that rare CD8+ LyP cases may exist with CD30-negativity.

Emerging azithromycin-resistance among the Neisseria gonorrhoeae strains isolated in Hungary.

BACKGROUND: In the 1990s, azithromycin became the drug of choice for many infectious diseases but emerging resistance to the drug has only been reported in the last decade. In the last 5 years, the National Neisseria gonorrhoeae Reference Laboratory of Hungary (NNGRLH) has also observed an increased number of N. gonorrhoeae strains resistant to azithromycin. The aim of this study was to determine the most frequent sequence types (ST) of N. gonorrhoeae related to elevated levels of azithromycin MIC (minimal inhibitory concentration). Previously and currently isolated azithromycin-resistant strains have been investigated for the existence of molecular relationship. METHODS: Maldi-Tof technic was applied for the identification of the strains isolated from outpatients attending the reference laboratory. Testing antibiotic susceptibility of azithromycin, cefixime, ceftriaxone, tetracycline, spectinomycin and ciprofloxacin was carried out for all the identified strains, using MIC strip test Liofilchem(®). N. gonorrhoeae multiantigen sequence typing (NG-MAST) was performed exclusively on azithromycin-resistant isolates. A phylogenetic tree was drawn using MEGA6 (Molecular Evolutionary Genetics Analysis Version 6.0) Neighbour-Joining method. RESULTS: Out of 192 N. gonorrhoeae isolates, 30.0 % (58/192) proved resistant to azithromycin (MIC > 0.5 mg/L). Of the azithromycin-resistant isolates, ST1407, ST4995 and ST11064 were the most prevalent. Based on the phylogenetic analysis, the latter two STs are closely related. CONCLUSIONS: In contrast to West-European countries, in our region, resistance to azithromycin has increased up to 30 % in the last 5 years, so the recommendation of the European Guideline -500 mg of ceftriaxone combined with 2 g of azithromycin as first choice therapy against N. gonorrhoeae- should be seriously considered in case of Hungary.

[Sexually transmitted coinfections. HIV coinfections]. / Szexuálisan terjedo koinfekciók. HIV koinfekciók.

Coinfections of sexually transmitted infections are frequent due to the same transmission routes which may facilitate the transmission of other sexually transmitted infections. Sexually transmitted coinfections are associated with atypical and generally more severe clinical features, more complications, resistency to treatment, unfavourable outcome, and worse prognosis. Sexually transmitted infections may increase the likelihood of acquiring and transmission of HIV infection. The authors summarize the most important characteristics of sexually transmitted infections (such as HIV and hepatitis B virus, HIV and hepatitis C virus, HIV and syphilis, HIV and gonorrhoeae, HIV and chlamydia coinfections). These infections are more frequent in HIV infected patients than in the normal population. The shared transmission routes, impairment of the immune response, elevated cytokine levels and the associated inflammatory milieu produce local tissue damage, breaches in mucosal epithelium, which increases the risk of human immunodeficiency virus infection. Regular screening for sexually transmitted infections, use of more sensitive diagnostic methods, improved reporting and avoidance of unsafe sexual behaviour among certain subpopulations as well as education are essential in the prevention of sexually transmitted coinfections.

[Skin symptoms associated with human immunodeficiency virus infection]. / A humán immundeficientia vírus fertozéséhez társuló bortünetek.

The recently observed accelerated increase of human immunodeficiency virus infection in Hungary poses a major public concern for the healthcare system. Given the effective only but not the curative therapy, prevention should be emphasized. Current statistics estimate that about 50% of the infected persons are not aware of their human immunodeficiency virus-positivity. Thus, early diagnosis of the infection by serological screening and timely recognition of the disease-associated symptoms are crucial. The authors' intention is to facilitate early infection detection with this review on human immunodeficiency virus-associated skin symptoms, and highlight the significance of human immunodeficiency virus care in the everyday medical practice.

[Anal cytology]. / Anális citológia.

INTRODUCTION: The incidence of anal cancer has increased in recent decades, particularly among human immunodeficiency virus infected men who have sex with men. Anal intraepithelial neoplasia is a potential precursor lesion of anal cancer. Anal cytology is the primary screening test for anal intraeptithelial neoplasia. AIM: The authors aimed to analyze the results of anal cytology of patients with human immunodeficiency virus infection at the National Centre of STD, Department of Dermatology, Dermatooncology and Venereology, Semmelweis University. METHOD: 155 anal cytological examinations were performed in 140 patients between November 1, 2012 and August 31, 2014. RESULTS: 44% of patients were found to have anal dysplasia, and only 1.6% of patients had high-grade lesions. This rate is lower as compared to published studies including larger number of patients. CONCLUSIONS: The study underlines the necessity of screening for anal lesions in the population at-risk.

[Syphilitic glomerulonephritis: case report and review of the literature]. / Veseérintettség syphilises fertozésben: esetismertetés és a szakirodalom áttekintése.

The authors report the history of a patient with syphilitic glomerulonephritis, a rare complication of syphilis. The patient was admitted to the hospital with clinical symptoms of neurosyphilis. During his hospital stay urine analysis revealed an extremely high proteinuria, that had not been known before. Intravenous penicillin treatment improved the renal protein loss, but it took a total of six months until complete resolution was achieved. The serology that confirmed the syphilis, the concomitant nephrotic syndrome and the improvement after penicillin therapy met the criteria of syphilitic glomerulonephritis. This case prompted the authors to review the literature about this rare complication of syphilis that has a great clinical significance.

[Lymphogranuloma venereum: the first Hungarian cases]. / Lymphogranuloma venereum: elso hazai esetek.

Lymphogranuloma venereum is a sexually transmitted infection caused by the Chlamydia trachomatis serovars L1-3. It has been found to be endemic in tropical countries. In the last decades several cases have been reported in Western Europe, particularly in men who have sex with men population infected with human immunodeficiency virus. The authors present three cases of lymphogranuloma venereum infections, observed at their department in 2013 and 2014. The three human immunodeficiency virus infected patients who belonged to men who have sex with men population had casual sexual contacts in Western Europe. The symptoms included urethral discharge, discomfort and inguinal lymphadenomegaly in two patients, and rectal pain, discharge and perianal ulceration in one patient. The diagnosis was confirmed by nucleic acid amplification test performed in samples obtained from urethral discharge and exudate of perianal ulcer; lymphogranuloma venereum 2b serovars were demonstrated in two patients and serovar 2 in one patient. Doxycyclin (daily dose of two times 100 mg for 21 days) resolved the symptoms in all cases. The authors conclude that lymphogranuloma venereum is a diagnostic challenge in Hungary, too. It is important to be aware of the altered clinical features of this disease to prevent complications and spreading.

Incidence and antimicrobial susceptibility of Neisseria gonorrhoeae isolates from patients attending the national Neisseria gonorrhoeae reference laboratory of Hungary.

BACKGROUND: The Hungarian national guidelines for the treatment of gonorrhoea were published in 2002 but are now widely considered to be outdated. Improved knowledge is needed with respect to the epidemiology and antimicrobial susceptibility of Neisseria gonorrhoeae strains currently circulating in Hungary not least for the construction of updated local recommendations for treating gonorrhoea. European guidelines are based mostly on western European data raising concerns locally that recommended treatments might not be optimised for the situation in Hungary. We report our recent study on the distribution of antibiotic resistance in various Hungarian (East European) Neisseria gonorrhoeae strains isolated from patients with gonorrhoea over the past four years. METHODS: Between January 2010 and December 2013, isolates of N. gonorrhoeae were obtained from sexually active individuals during medical examination at the STD Center of Semmelweis University in Budapest. The minimal inhibitory concentrations (MIC) of azithromycin, cefixime, ceftriaxone, ciprofloxacin, penicillin, tetracycline and spectinomycin were determined to establish the antimicrobial susceptibility of the strains currently circulating in patients that attend our clinic. RESULTS: Among the 9097 patients tested, 582 had an N. gonorrhoeae infection as detected by culture. The isolates were all sensitive to ceftriaxone and spectinomycin and 581/582 strains were sensitive to cefixime. In contrast, the number of detected strains with elevated azithromycin MIC did increase over the time period examined to approximately 16% in 2013. There was a high percentage of detected resistance to penicillin (77%), tetracycline (86%), and ciprofloxacin (66%) in the isolates examined in this study. CONCLUSION: Current European guidelines recommend 2 g azithromycin in addition to 500 mg ceftriaxone as first choice therapy for gonorrhoea. For the purposes of revising the Hungarian national treatment guidelines, apparent increasing resistance to azithromycin during the last four years should be accounted for. It is also clear that penicillin, tetracycline and ciprofloxacin are inappropriate treatment measures at least locally. We also recommend that culture should form part of the diagnostic pathway of gonorrhoea, followed by antibiotic susceptibility testing with MIC determination. This will provide valuable continued monitoring of antibiotic resistance development in strains of Neisseria gonorrhoeae circulating in Hungary.

Calcinosis Prevalence in Autoimmune Connective Tissue Diseases-A Retrospective Study.

Background/Objectives: Calcinosis cutis is the deposition of insoluble calcium salts, which may cause inflammation, ulceration, pain, and restricted joint mobility. It rarely develops in damaged tissues (dystrophic subtype), most frequently in autoimmune connective tissue diseases (CTDs), but there is very limited data on the prevalence. Also, therapy remains an unsolved issue. In this study, we aimed to collect data on the prevalence of calcinosis in CTD patients to highlight that it is a considerable problem. Methods: A retrospective study was conducted in our department to assess the epidemiology of dystrophic calcinosis in CTDs between January 2003 and January 2024. Results: A total of 839 CTD patients were identified, of whom 56 had calcinosis (6.67%). The mean age of the calcinosis patients at diagnosis of underlying CTD was 41.16 ± 19.47 years. The mean time interval from the onset of calcinosis was 5.96 ± 8.62 years. Systemic sclerosis was the most common CTD complicated by calcinosis (n = 22). Conclusions: Our results are comparable to those reported previously in the literature. Although calcinosis is rare in the overall population, it is a present and unsolved problem in CTD patients. Therefore, further studies are needed on the factors involved in the development and progression of calcinosis as well as its treatment.

Comparative analysis of IL6 and IL6 receptor gene polymorphisms in mastocytosis.

Mastocytosis is a rare disease with reported high interleukin-6 (IL6) levels influencing disease severity. The present study investigated polymorphisms within the genes that encode IL6 and its receptor (IL6R) in relation to mastocytosis development in a case-control design. Analysis of the IL6R Asp358Ala polymorphism showed that carriers of the AA genotype had a 2·5-fold lower risk for mastocytosis than those with the AC or CC genotypes. No association with mastocytosis was found for the IL6-174G/C polymorphism, however, it may influence the effect of IL6R polymorphism. To the best of our knowledge this is the first study analysing IL6/IL6R polymorphisms in mastocytosis.

Impact of effective tumor necrosis factor-alfa inhibitor treatment on arterial intima-media thickness in psoriasis: results of a pilot study.

BACKGROUND: Psoriasis is associated with higher incidence of atherosclerotic comorbidities. Sustained arterial wall inflammation mediated by common cytokines of psoriasis and atherogenesis precedes atherosclerotic plaque development. Increased intima-media thickness (IMT) is an accepted indicator of subclinical atherosclerosis and has been reported in severe psoriasis. OBJECTIVE: This pilot study aimed to clarify whether effective long-term tumor necrosis factor-alfa inhibition decreases IMT in psoriasis. METHODS: In 16 patients with severe psoriasis, the Psoriasis Area and Severity Index score was calculated before therapy (etanercept, infliximab, adalimumab) and after 6-month treatment. Simultaneously, carotid and brachial IMT was measured by high-resolution, B-mode ultrasonography. Difference between initial and 6-month IMT values was determined for monitored arteries collectively and separately in carotid and brachial arteries. RESULTS: All of 16 patients achieved Psoriasis Area and Severity Index 75, and 14 of 16 achieved Psoriasis Area and Severity Index 90 improvement. In the group of patients without initial calcified atherosclerotic plaques (13 of 16) significant IMT decrease was detected when arteries were measured collectively (P = .0002). Initial and follow-up data differed significantly also at individual analysis of carotid (P = .011) and brachial (P = .006) arteries. Eleven of 13 patients had initial carotid IMT exceeding age-adjusted normal values. The other group (3 of 16) with initial manifest plaques showed increasing IMT tendency. Their baseline ultrasonography revealed carotid IMT above the upper limit of healthy adults' age-adjusted values. LIMITATIONS: Study limitation involves small patient numbers, self-controlled study design, and lack of patients' stratification according to common cardiovascular risk factors. CONCLUSION: In our pilot study effective tumor necrosis factor-alfa inhibition was found to decrease IMT in psoriatic patients without irreversible atherosclerotic plaques. Further analysis is recommended to confirm and complete our primary observations.

[Purulent keratoconjunctivitis due to Neisseria gonorrhoeae and Chlamydia trachomatis coinfection]. / Conjunctivitis gonorrhoica szövodése Chlamydia trachomatis-infekcióval.

Gonococcal conjunctivitis is a rare infection induced by Neisseria gonorrhoeae and it usually manifests as a hyperacute purulent conjunctivitis. Ocular access of the infectious secretion during sexual intercourse is the way of transmission among adults. Inclusion conjunctivitis caused by the serovars D-K of Chlamydia trachomatis also affects the sexually active population. Authors present a case of a 33-year-old homosexual man who was treated for late latent syphilis formerly. Clinical symptoms were yellow purulent discharge for 3 weeks without any urological or upper respiratory tract symptoms. Conjunctival Neisseria gonorrhoeae and Chlamydia trachomatis infection was identified using cultures and polymerase chain reaction; pharyngeal swab culture and polymerase chain reaction showed positive results for both pathogens. The patient was probably under influence of party drugs at the time of sexual abuse when he became infected. After parenteral and oral cephalosporin and azithromycin therapy the patient had complete recovery within three weeks.

[Clinical observations in cutan mastocytosis]. / Klinikai tapasztalataink cutan mastocytosisban.

INTRODUCTION: Mastocytosis is a clonal mast cell proliferative disease, divided into cutaneous and systemic forms. The characteristic symptoms are caused by neoplastic mast cell infiltrations in different organs and/or the release of mediators. AIM: The aim of the authors was to summarize their clinical observations in patients with mastocytosis. METHOD: 22 adult patients diagnosed consecutively with mastocytosis were enrolled in the study. Skin and bone marrow biopsies were taken to establish the diagnosis and perform c-KIT mutation (D816V) analysis. RESULTS: One of the 22 patients had teleangiectasia macularis eruptiva perstans, while 20/22 patients had urticaria pigmentosa. All patients had cutaneous lesions. In 12 patients iliac crest biopsy was performed and 9 of them had bone marrow involvement, classified as indolent systemic mastocytosis. The c-kit mutation D816V was found in one subject both in skin and bone marrow samples. The patients were treated with antihistamine, PUVA, interferon-α or imatinib. CONCLUSIONS: The authors draw attention to this rare disease in order to help recognition of relevant signs and symptoms and establish an early diagnosis.

[Characteristics and physiologic role of female lower genital microbiome]. / A noi alsó genitalis traktus mikrobiom tulajdonságai és szerepe.

Vaginal microbiome is substantial in the maintenance of vaginal health and defense against pathogenic microorganisms. New techniques, including next-generation sequencing broadened our knowledge with new findings on the composition and functions of the vaginal microbiome. Improvement of laboratory techniques provides a better understanding of the diverse patterns of the vaginal microbiome in reproductive-age women and their longitudinal changes in both healthy and dysbiotic conditions. The objective of this review was to summarize the basic learning of the vaginal microbiome. In the era of traditional cultivation-dependent techniques, the role of Lactobacilli in maintenance of the vaginal homeostasis, in lactic acid and various antimicrobial compounds production and in genital defense has been delineated. Much of our knowledge about the healthy microbial flora comes from cultivation-independent molecular-based techniques. The vaginal microbiome alters throughout a woman's life, its function develops fully in reproductive age. Healthy vaginal flora typically shows Lactobacillus predominance with a pH lower than 4.5, the healthy flora is dominated by one or two species of Lactobacillus, predominantly L. crispatus, L. iners, L. gasseri, L. jensenii. The review provides background on the 5 community state types of Lactobacillus communities, their characteristics, demographic occurrence, the type shifts, the terminal changes of the dominant bacterial communities, and the comparison of them to non-Lactobacillus dominated healthy microbiomes. The microbiome contributes to the local immune response of the vaginal mucous membrane, in defense to pathogens and maintenance of immunologic tolerance to physiologic changes. Bacterial vaginosis is a clinical syndrome characterized by pathologic vaginal microbiome, Lactobacillus community decreased in abundance and replaced by different anaerobes with great diversity. In pregnant women, bacterial vaginosis increases the risk of miscarriage, abortion, preterm birth, chorioamnionitis and endometritis. In non-pregnant women, bacterial vaginosis is associated with an increased risk of upper genital tract and urinary tract infections. Women with bacterial vaginosis are more sensitive to sexually transmitted infections and acquisition of HIV. Women with bacterial vaginosis may transmit HIV virus to their partner and newborn.

The Possible Clinical Significance of a Decreased Serum Level of Soluble PD-L1 in Discoid Lupus Erythematosus, but Not in Subacute Cutaneous Lupus Erythematosus-A Pilot Study.

Cutaneous lupus erythematosus (CLE) is an autoimmune skin disease with various clinical forms, including the subtypes of discoid lupus erythematosus (DLE) and subacute cutaneous lupus erythematosus (SCLE). The altered function of the programmed cell death 1/programmed cell death ligand 1 (PD-1/PD-L1) axis in CLE pathogenesis has been suggested. Here, the soluble forms of PD-1 (sPD-1) and PD-L1 (sPD-L1) were explored in untreated DLE and SCLE. Levels of sPD-1 and sPD-L1 were determined by enzyme-linked immunosorbent assay in serums of 21 DLE, 18 SCLE, 13 systemic lupus erythematosus (SLE) patients and 20 healthy controls (HCs). Differences between patient groups and HCs, and the association between clinical activity of skin symptoms and sPD-1/sPD-L1 levels were analyzed with Mann-Whitney U-test and Spearmann's correlation. Regarding sPD-1 levels, no statistically significant differences were found between DLE and SCLE groups, nor compared to HCs. As for sPD-L1, a significantly lower level was found in the DLE group compared to the SCLE and HC groups (p = 0.027 and p = 0.009, respectively). In SLE, significantly higher sPD-1 was found compared to HCs (p = 0.002). No association between skin symptom activity and sPD-1/sPD-L1 levels was found in CLE. Alterations of the inhibitory effect of sPD-L1 on T-cell activity might elucidate the differences between DLE and SCLE.

[Characteristics of the course of lupus erythematosus panniculitis in a retrospective analysis of 17 patients]. / A lupus erythematosus panniculitis lefolyásának jellegzetességei 17 betegünk retrospektív vizsgálata alapján.

INTRODUCTION: Lupus erythematous panniculitis (LEP) is a rare type of chronic cutaneous lupus erythematous. Clinical characteristics are tender, subcutaneous nodules, erythematous plaques. Disfigurement of face and body might develop which affects the patient's quality of life. LEP can be the first sign of systemic lupus erythematous (SLE). OBJECTIVE: Our aim was to review the clinicopathological characteristics and the course of LEP through our own patients. METHODS: We retrospectively analyzed the clinical records of 17 LEP patients at Semmelweis University's Department of Dermatology, Venerology and Dermatooncology between 2000 and 2022. RESULTS: The male : female ratio was 1 : 16, average age was 37.8 years. Lesion localisations were proximal lower (8/17) and upper extremities (7/17), face (4/17), breast (3/17), chest (2/17), buttocks (2/17), back (1/17) and distal lower extremity (1/17). Lesion morphologies were nodules (11/17), plaques (7/17), lipoatrophy (4/17), ulceration (3/17), calcification (1/17). Discoid changes covered in 6 cases. In 10 cases, systemic symptoms were observed (arthritis (4/17), haematological (5/17), renal (2/17), anti-phospholipid syndrome (2/17). 7 patients fulfilled the EULAR/ACR criteria for SLE. Histology showed mixed type panniculitis in 8, lobular in 3 cases. Average time until diagnosis was 24.3 months. Among all our SLE patients, skin symptoms regressed following systemic immunosuppressive treatment. LEP patients with only skin manifestation were often resistant for the therapy of cutaneous lupus erythematous. CONCLUSION: The diagnosis of LEP often takes months or years. Wider knowledge of LEP would shorten the time to diagnosis, preventing disfigurement and possible damage of internal organs. Based on our observations, LEP without SLE might be treated with early immunosuppression. Orv Hetil. 2023; 164(5): 172-178.

Scrofuloderma and granuloma annulare-like lesions: Challenges of diagnosing cutaneous tuberculosis in developed countries.

Tuberculosis remains a global health concern, as the increasing levels of urban poverty, higher number of immunodeficient patients and the development of drug resistance threaten the overall efforts made to induce a downward trend for the disease. Scrofuloderma, also known as tuberculosis cutis colliquativa is a subtype of cutaneous tuberculosis. Here we detail a case of a 70-year-old female patient presented with unilateral, left-sided, multiple palpable, painful, ulcerated and purulent cervical nodules, accompanied by persistent generalized erythematous popular granuloma annulare-like skin lesions on the upper extremities. Based on the result of the PCR assay, culture, imaging and histopathological findings, the diagnosis of scrofuloderma was established. To achieve prompt diagnosis and early treatment, it is crucial to include scrofuloderma in the differential diagnosis of ulcerated lesions in developed countries as well, and also be aware of the additional clinical symptoms, such as granuloma annulare-like lesions, possibly accompanying cutaneous tuberculosis.

STIs during the COVID-19 Pandemic in Hungary: Gonorrhea as a Potential Indicator of Sexual Behavior.

The social distancing measures introduced due to the COVID-19 pandemic may have affected the sexual behavior of the population. We collected data retrospectively from the National STD Center of Hungary. The overall patient influx data of the STD Center and the number of patients diagnosed with syphilis, chlamydia, and gonorrhea infections were assessed in the three-month period of 2020 when the strict governmental lockdown was introduced in Hungary. Data were compared to the pre- and post-lockdown quarters of 2020 and matched to the respective quarters of 2018 and 2019. The number of patients diagnosed with syphilis and chlamydia infections in 2020 during the lockdown decreased compared to 2018 and 2019, while the number of gonorrhea cases increased. The lower number of STI screenings resulted in a significant decrease in asymptomatic syphilis and chlamydia case numbers. However, the growing number of gonorrhea cases in 2020 during lockdown highlights that sexual behavior remained unchanged regardless of restrictions. Therefore, gonorrhea may be considered as an indicator of STI incidences during the pandemic.

[Frequency and antibiotic resistance of Ureaplasma urealyticum and Mycoplasma hominis in genital samples of sexually active individuals]. / Az Ureaplasma urealyticum és a Mycoplasma hominis antibiotikum-érzékenysége és gyakorisága szexuálisan aktív egyének genitális mintáiban.

UNLABELLED: Ureaplasma urealyticum and Mycoplasma hominis have important role among the causative agents of sexually transmitted diseases. AIM: The aim of the study was to determine the frequency and antibiotic resistance of Ureaplasma urealyticum and Mycoplasma hominis in genital samples obtained from patients examined in the Sexually Transmitted Diseases Centre of the Department of Dermatology, Venerology and Dermatooncology, Semmelweis University, Budapest between May 1, 2008 and July 31, 2010. PATIENTS AND METHODS: Samples were taken from the urethra in men and from the cervix and urethra in women by universal swab (Biolab®) into Urea-Myco DUO kit (Bio-Rad®) and were incubated for 48 hours at 37 C°. Antibiotic sensitivity of positive samples was determined in U9 bouillon using SIR Mycoplasma kit (Bio-Rad®). RESULTS: Samples for 4154 patients aged 16-60 years were examined. In 247/4154 samples (6%) U. urealyticum and in 26/4154 samples (0.63%) M. hominis was isolated from the genital tract. Most U. urealyticum and M. hominis strains (75% and 77%, respectively) were cultured from cervix, while the remaining 25%, and 23% from the male and female urethra, respectively. U. urealyticum and M. hominis were most commonly detected in patients aged between 21 and 40 years. The majority of U. urealyticum strains were sensitive to tetracycline (94%), doxycycline (95%), azithromycin (88%) and josamycin (90%), but were resistant to ofloxacin (21%), erythromycin (85%) and clindamycin (79%). Seventy-seven percent of the U. urealyticum strains were simultaneously resistant to erythromycin and clindamycin, suggesting that ex iuvantibus therapies may select cross-resistant strains to both antibiotics. The resistance of M. hominis to clindamycin, doxycycline, ofloxacin and tetracycline varied between 4% and 12 %. CONCLUSIONS: Because none of the strains was sensitive to all examined antibiotics, the antibiotic sensitivity of U. urealyticum and M. hominis strains should be determined. The high rate of ofloxacin, erythromycin and clindamycin resistance should be considered in the therapy of U. urealyticum infections in Hungary. This is the first such a clinical microbiological study in this topic in Hungary.

[Meningovascular neurosyphilis as the cause of ischemic cerebrovascular disease in a young man]. / Meningovascularis neurosyphilis miatti fiatalkori ischaemiás cerebrovascularis betegség.

Authors report a case of a 35-year-old male with right-sided mild paresis, incontinence, dysexecutive syndrome, short-term memory loss and behavioral changes. Bilateral cerebral infarcts in the region of the caudate nuclei and the adjacent white matter were proved by brain MRI and multiple stenoses of the branches of Willis-circle were confirmed by MR angiography. Elevated protein level and pleocytosis were found in the cerebrospinal fluid with intrathecal IgG synthesis. Serum rapid plasma reagin, Treponema pallidum Particle Agglutination test, Treponema pallidum ELISA, liquor Venereal Disease Research Laboratory tests were positive. Meningovascular neurosyphilis was diagnosed. 24M U/day intravenous penicillin-G treatment was given for 14 days. The patient has vascular dementia due to the bilateral strategic infarcts disconnecting the prefrontal circuits; his symptoms are similar to general paresis. Laboratory and radiologic improvement was observed. Still, the patient have severe residual cognitive decline.
