Abstract
This study was aimed at the evaluation of cell proliferation, p53 level and apoptotic index by immunohistochemical methods in canine oral papillomatosis. The study material comprised of tumor tissue samples taken from six dogs being admitted to the Pathology Department of Faculty of Veterinary Medicine, Kafkas University, Kars, Türkiye. Choice of immunohistochemical staining was avidin-biotin peroxidase method. Cases of canine oral papillomatosis, determined to have been caused by canine papillomavirus-1, were found to have a rather high cell proliferation index. Furthermore, all cases were immunohisto-chemically demonstrated to carry a mutant p53 gene. Despite the mutation of p53 gene, the shift in the Bax/Bcl-2 ratio of dogs diagnosed with tumor was in favor of the pro-apoptotic Bax gene. The apoptotic mechanism was determined to occur through both the caspase-dependent and caspase-independent pathways. While the lesions occupied the entire oral cavity in some cases, histopathologically, malignant transformation was not detected in any of the six cases.

Abstract
The expansion of the private healthcare sector in some low-income and middle-income countries (LMICs) has raised key questions and debates regarding the governance of this sector, and the role of actors representing the sector in policy processes. Research on the role played by this sector, understood here as private hospitals, pharmacies and insurance companies, remains underdeveloped in the literature. In this paper, we present the results of a scoping review focused on synthesising scholarship on the role of private healthcare sector actors in health policy processes pertaining to health service delivery and financing in LMICs. We explore the role of organisations or groups-for example, individual companies, corporations or interest groups-representing healthcare sector actors, and use a conceptual framework of institutions, ideas, interests and networks to guide our analysis. The screening process resulted in 15 papers identified for data extraction. We found that the literature in this domain is highly interdisciplinary but nascent, with largely descriptive work and undertheorisation of policy process dynamics. Many studies described institutional mechanisms enabling private sector participation in decision-making in generic terms. Some studies reported competing institutional frameworks for particular policy areas (eg, commerce compared with health in the context of medical tourism). Private healthcare actors showed considerable heterogeneity in their organisation. Papers also referred to a range of strategies used by these actors. Finally, policy outcomes described in the cases were highly context specific and dependent on the interaction between institutions, interests, ideas and networks. Overall, our analysis suggests that the role of private healthcare actors in health policy processes in LMICs, particularly emerging industries such as hospitals, holds key insights that will be crucial to understanding and managing their role in expanding health service access.

Abstract
In this study, in order to reveal the immune response against the disease in naturally infected sheep with SPPV, the expressions of various pro- or anti-inflammatory cytokines such as tumour necrosis factor alpha (TNF-α), interferon gamma (IFN-γ), interleukin-1beta (IL-1β), interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10) and interleukin-12 (IL-12) were evaluated immunohistochemically. The material of this study consisted of tissue samples taken from 24 sheep, which were brought as dead for routine histopathological examination to the Department of Pathology. Avidin-biotin-peroxidase method was used for immunohistochemistry. Characteristic pox lesions were observed in the skin, lungs and kidneys. In histopathological examinations, pox cells, which are very characteristic for the diagnosis of the disease, were observed in all three tissues. Capripoxvirus nucleic acid was detected in 8 of the 24 tissues. Samples were sequenced, and a phylogenetic tree was constructed with reference strains from GenBank. Strains from the study clustered with sheeppox virus references. In conclusion, the levels of pro-inflammatory cytokines such as TNF-α, IFN-γ, IL-1β, IL-2, IL-8 and IL12 (Th1) were much more dominant compared to the levels of anti-inflammatory cytokines: IL-10 and IL-6 (Th2). This supported the fact that the cellular immune response is much more effective than the humoral immune response in sheeppox.

Abstract
BACKGROUND The influence of healthcare system factors on treatment pathways for breast cancer has been studied extensively in lower-middle-income countries (LMICs), but in upper-middle-income countries (UMICs), this area is understudied. This article focuses on the experiences of breast cancer patients in Türkiye, a UMIC with a universal healthcare system. It explores variations in treatment pathways based on the type of health insurance provider (private or state). METHODS The study uses an exploratory qualitative method based on in-depth interviews with 12 breast cancer patients. The inclusion criteria were Turkish nationality, female gender, and having received treatment from a private hospital within one year of the interview. A purposeful sampling strategy was employed to recruit patients who had either social health insurance only or who had private health insurance in addition to their social health insurance. A two-stage thematic analysis of the interview data was conducted. First, we examined whether the type of insurance provider makes a difference in treatment pathways; we then identified healthcare system factors that explain these differences. RESULTS The study revealed two distinct pathways to treatment. These differ in terms of financial protection, service coverage, and patients' sense of equity. Patients with private insurance reported easy access to timely and comprehensive treatment. Those without, however, had to navigate complicated routes to treatment; they generally had to resort to seeking treatment from more than one hospital. We found two healthcare system factors that explained the differences: a failure to fully enforce the mandates of the state's social health insurance in the private hospital sector and growing reliance on private insurance to gain access to essential services. CONCLUSIONS Based on data from the Turkish case, we conclude that healthcare system factors are indeed influential in shaping treatment pathways for breast cancer in UMICs with universal healthcare. These factors include a failure to fully enforce the mandates of the state's social health insurance programme in the private hospital sector and a growing reliance on private insurance to gain access to essential services. We note that this contrasts dramatically with the situation in LMICs, where the main factors are low-quality care and shortages of medical staff, medicines, and technologies.

Abstract
Universal health coverage (UHC) has been elevated to the status of a global policy target, but this was at the expense of losing its aspirational meaning. As a case in point, Turkey has been one of the countries that has achieved UHC, according to the technocratic definition. This article employs a combination of deductive and inductive thematic analysis methods to explore patient organisation (PO) perspectives on the Turkish health-care system based on 26 respondent interviews from 19 POs in Istanbul. Highlighting the inadequacy of the technocratic definition of UHC, the article maintains that an analysis of PO perspectives opens the way for a nuanced and bottom-up assessment of essential service coverage and financial protection by identifying elusive gaps in both dimensions that would otherwise be lost in generalist evaluations. The findings also underline the importance of keeping intact the UHC's aspirational element to enable POs to participate in the politics of priority setting in health care.

Abstract
The Emergency Social Safety Net (ESSN) programme, which was launched in 2016, has become the central element of the humanitarian response to the plight of Syrian refugees in Turkey and an instrument of European migration control policies. This paper offers a contextual analysis of this European Union-funded cash assistance scheme by examining the modes of interaction between its major assumptions and the broader humanitarian response in the context of Turkey. It finds that the ESSN comes with compromises on humanitarian principles and standards, amplifies the protection and assistance divide, and fails to address the realities of Turkey with respect to the country's housing and labour markets and weak protection framework. The paper concludes that a more inclusive approach to eligibility and higher transfer payments can contribute to the addressing of assistance needs provided that cash support is combined with robust protection programming and the implementation of sector-specific projects and policies.

Abstract
B cells play a major role in the pathophysiology of myasthenia gravis (MG) with their ability to produce disease specific, pathogenic antibodies. However, their status during disease development and follow-up stages of the disease in the peripheral blood may need further studies to determine useful markers. In this study, we aimed to detect B cell associated factors concerning immunosuppressive treatment in generalized non-thymomatous MG patients. Although CD19+ B cell distribution did not vary among disease subgroups, expressions of both CD38 and BAFFR were altered on B cells in MG patients under immunosuppressive therapy. Serum levels of BAFF were elevated in untreated MG patients as compared to treated MG patients and healthy controls. B cell activation factors may show profound alterations due to immunosuppression.

Abstract
Background Stroke is the most frequent reason of neurological dysphagia Electrophysiological studies can be used to evaluate oral, pharyngeal and initial phase of esophageal phase. Aims This study aims to noninvasively evaluate mastication, mimic, and tongue muscles of stroke patients, which play an important role in the oral phase of swallowing process and compare them with healthy individuals. Setting and Design This study was conducted at the Physical Medicine and Rehabilitation Clinic of our hospital between January 2014 and December 2016. Materials and Methods Fifty-one patients who were admitted to our clinic with stroke and 51 healthy individuals were evaluated for the study. Demographic features of individuals were recorded. The swallowing intervals and motor action potentials (MAPs) of trigeminal, facial and hypoglossal nerves were measured. After four weeks of treatment schedule, patients were re-evaluated. Statistical Analysis The Wilcoxon Signed Rank test, the Mann-Whitney U test and Fisher exact test were used in this study. Results The all swallowing intervals were found prolonged compared to the healthy controls (P < 0.05). The MAPs of the masseter, orbicularis oculi, and intrinsic tongue muscles were significantly lower in patient group (P < 0.05). After treatment, we found significant improvement for all parameters in patient group, but the swallowing intervals were still significantly prolonged, and MAPs of these muscles were still lower (P < 0.05). Conclusion Although swallowing is examined as different phases, the process is complicated and should be evaluated totally. In post-stroke dysphagia, oral phase of swallowing process is as important as phayngeal phase and perioral, mastication, and tongue muscles are influenced even in an early period as a month.

Abstract
OBJECTIVES The aim of this study is to evaluate the efficacy of genicular nerve block (GNB) and intraarticular corticosteroid injection (IACSI) in patients with knee osteoarthritis (OA). METHODS Forty patients with Kellgren-Lawrence grade 2-4 knee OA were included for the study. Patients were divided into two groups randomly as IACS and IACS + GNB groups. All patients were evaluated with ultrasound for cartilage thickness, patellar tendon thickness, quadriceps tendon thickness and quadriceps muscle cross-sectional area (QMA). Pain intensity of the patients was evaluated with visual analogue scale and the Leeds Assessment of Neuropathic Symptoms and Signs pain scale. Functional status of the patients was evaluated with Western Ontario and Mc Master Universities Osteoarthritis Index. Quality of life of the patients was assessed with Nottingham Health Profile (NHP). All assessments were measured and compared at baseline, 1st month and 3rd month after treatment. RESULTS All evaluation parameters were significantly improved in IACSI and IACSI + GNB groups. However, the improvement was better in IACSI + GNB group compared to those in IACSI group in terms of all evaluation parameters except QMA (0.10 ± 0.18 and 0.11 ± 0.22, respectively) and NHP scores in 1st month evaluation (- 3.11 ± 6.99 and - 3.54 ± 1.74, respectively). CONCLUSIONS When combined with IACSI, GNB yields better analgesic effect and improves function in patients with knee OA compared to only IACSI.

Abstract
AIM To investigate the efficacy of primary hypertension (HTN) on the treatment prognosis of patients with postmenopausal osteoporosis (PMOP). METHODS 45 patients who were diagnosed as PMOP with lumbar and/or femur neck bone mineral density screening (BMD) but have no history of PMOP treatment including calcium and vitamin D, have comorbid primary HTN and treated with a vasodilator antihypertensive drug at least a year were included to the study. Control group was constituted with 44 patients with PMOP at same age but have no comorbidity. Demographic features including age, height, weight, occupation, educational level menarche and menopause age, clothing style, daily intake of calcium, smoking and/or alcohol consumption, daily physical activity level, personal history of fragility fracture or in mother and duration of primary HTN diagnosis were recorded. Biochemical parameters were also recorded. Patients were treated with bisphosphonate, calcium and vitamin D and same parameters were evaluated at the end of first and fifth year. RESULTS Demographic and disease characteristics were not different between groups before treatment (p > 0.05). In group analysis, there was significant improvement in lumbar and femur neck T scores of PMOP + HT and PMOP groups after 1 and 5 years of treatment compared to baseline (p < 0.05) Lumbar and femur neck T score variations between the baseline, first and fifth years of treatment were not significantly different in PMOP + HT and PMOP groups (p < 0.05). CONCLUSIONS Although the results vary between populations, primary HTN does not have an impact on the prognosis of PMOP treatment in Turkish population.

Abstract
OBJECTIVES The initiation timing of rehabilitation in children with obstetric brachial plexus palsy is controversial. The aim of the present study is to evaluate the effectiveness of rehabilitation timing to the functional outcomes of patients with obstetric upper trunk brachial plexus palsy. MATERIAL AND METHODS Twenty-nine patients, who did not previously received any rehabilitation programme but attended our outpatient clinic, were included for the study. The electrophysiological findings, obstetric characteristics, and demographic features of the patients were recorded. The range of motion (ROM) of shoulders, elbows, and wrists and the strength of the muscles associated with these joints were evaluated. Modified Mallet Scale (MMS) was used for functional evaluation. A 4-week rehabilitation programme was performed twice at 2-month intervals. Patients were divided into three groups according to their ages as follows: 1-3 years old (group 1), 3-5 years old (group 2), and 5-7 years old (group 3). The ROMs, muscle strengths, and MMS scores of the patients were all evaluated. RESULTS Two out of 29 patients were female (6.9%) and 27 were male (93.1%). All 29 patients had right upper extremity palsy (100%). The MMS scores, ROMs, and muscle strength of the upper extremities had improved in all the groups following the standardized rehabilitation programme. CONCLUSIONS A rehabilitation programme is the best choice of treatment before surgical procedures in patients with mild to moderate obstetric upper trunk brachial plexus palsy regardless of age and the initiation time.

Abstract
Introduction: Cerebrovascular disease is the second most common complication in individuals with tumours. The aim of this study was to investigate risk factors, biomarkers, etiology and prognosis of ischemic stroke in cancer patients (ISCPs). Methods: The medical records of 619 consecutive patients who were admitted with acute ischemic stroke from January 2012 to November 2014 were retrospectively evaluated. The patients were divided into two groups (group 1, patients with an active cancer prior to the onset of ischemic stroke; group 2, patients without an active cancer history). The demographic data, risk factors, NIHSS scores, thrombocyte count, D-dimer, fibrinogen and C reactive protein (CRP) level at admission, modified Rankin Scale (mRS) scores in the follow-up period and location of lesions on DWI were recorded. The Mann-Whitney U test, chi-squared test and logistic regression was used for analyzing data, p<0.05 being considered statistically significant. Results: A total of 46 (7.4%) ISCPs were included. Hyperlipidemia was significantly lower in the ISCP group (p=0.001). Elevated thrombocyte counts, D-dimer, fibrinogen and CRP levels at admission, acute multiple ischemic lesions, other causes, mortality in hospital and worse outcome were significantly related to ISCP (p<0.05). On logistic regression analysis, follow up mRS>3, acute multiple ischemic lesions located in more than one vascular territory (AMIMCT) and other causes were significantly associated with ISCP (p<0.001). Conclusion: In our study, other causes, AMIMCT and mRS>3 were more common in the ISCP group. We consider that CCS could be more suitable for detecting other causes than TOAST. Biomarkers could be important in the ISCP group.

Abstract
Background Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and Unified Dyskinesia Rating Scale (UDysRS) were developed as standard tools to rate Parkinson's disease (PD) and drug-induced dyskinesias of PD. As these scales have become widely used, there is a need for translation to non-English languages. Here we present the standardization for the Turkish translations. Methods The scales were translated into Turkish and then back-translated to English. These back-translations were reviewed by the MDS team. After cognitive pretesting, movement disorder specialists from nine centers tested 352 patients for MDS-UPDRS, and 250 patients for UDysRS. Confirmatory factor analyses (CFAs) were used to determine if the factor structures for the reference standards could be confirmed in the Turkish data. The comparative fit indexes (CFIs) for the scales were required to be 0.90 or higher. Exploratory factor analyses (EFAs) were conducted to explore the underlying factor structure without the constraint of a pre-specified factor structure. Results For both scales, the CFIs were 0.94 or greater as compared to the reference standard factor structures. The factor structures were consistent with that of reference standards, although there were some differences in some areas as compared to the EFA of the reference standard dataset. This may be due to the inclusion of patients with different stages of PD and different cultural properties of raters and patients. Conclusions These results demonstrate that the Turkish translations of MDS-UPDRS and UDysRS have adequate clinimetric properties. They are established as the official translations and can be reliably used in Turkish speaking populations.

Abstract
BACKGROUND Two types of watershed infarcts (WI) are recognized. Internal WI are usually attributed to either severe stenosis in large arteries or acute hypotensive events, whereas external WI are thought to be caused by embolism. The aim of this study was to determine the etiologic background and prognosis of external and internal WI in our patients. METHODS We reviewed the medical records and diffusion-weighted images of the patients who were admitted to our stroke unit with acute ischemic stroke between January 2012 and November 2014. The demographics, clinical features, radiologic investigations, and other etiologic tests of the patients with internal or external WI were recorded. We determined etiologic stroke subtypes according to the automated Causative Classification System. RESULTS Fifty-three patients with WI were detected in our registry. Twenty-two (41.5%) of them were women. The mean age was 69 ± 12.8 (33-98) years. Twenty-one (39.6%) patients had external WI: 7 (33.3%) of them had large-artery atherosclerosis (LAA), 8 (38.1%) patients had cardioembolism, 3 (14.3%) patients had stroke due to other causes (vasculitis; n = 3), and etiologic subtype was undetermined in 3 patients (14.3%). Thirty-two (60.4%) patients had internal WI: 21 (65.6.%) of them had LAA, 5 (15.6%) patients had cardioembolism, 3 (9.4%) patients had stroke due to other causes (aneurysm; n = 1, hypercoagulability due to chronic myeloid leukemia; n = 1, vasculitis; n = 1), and etiologic subtype of 3 (9.4%) patients remained cryptogenic. LAA was significantly associated with internal WI (P = .024). Hypertension was more common in patients with internal WI (P = .035). CONCLUSIONS In this series, cardioembolism was the most common etiologic subtype in the patients with external WI, whereas internal WI were significantly associated with LAA. Uncommon causes should also be investigated in cryptogenic patients.

Abstract
The herpesviruses infections in equides are caused by five different serotypes of viruses, belonging to family Herpesviridae. The goal of this study was to conduct a seroepidemiological investigation of equine herpesvirus type 1 (EHV-1) and type 4 (EHV-4) in horses and donkeys raised in two provinces and their villages in northeastern Turkey. A total of 666 samples from 423 horses and 243 donkeys that were not immunized against these infections were tested with ELISA. While 52.48% of tested horse sera was found to carry specific antibodies to EHV-1, 83.69% of these serums were found to carry specific antibodies to EHV-4. 51. Eighty-five percent of analyzed donkey samples tested positive for EHV-1 and 64.20% of these samples tested positive for EHV-4 antibodies. When the horse and donkey samples were evaluated together, 52.25% were seropositive for EHV-1 and 76.58% were seropositive for EHV-4. This study showed that EHV-1 and EHV-4 infections are quite common in the horses and donkeys being raised in the areas where the study was carried out. In addition, since the area where the study was carried out in the borders of Armenia and Georgia, the high level of seropositive results for these infections leads to the conclusion that we should consider the risk of diseases spreading to neighboring countries. This is the first study to serologically identify EHV-1 and EHV-4 infections in donkeys raised in Turkey.

Abstract
In this study, the physical examination of 22 cattle revealed clinical signs of malignant catarrhal fever (MCF). Peripheral blood leukocyte (PBL) samples of the 22 cattle, and nasal (n = 7) and conjunctival (n = 9) swab samples from 16 sheep from two different farms, were taken for laboratory examination. The clinical diagnosis of MCF in cows was confirmed by the detection of ovine herpesvirus type 2 (OvHV-2) DNA by polymerase chain reaction (PCR). OvHV-2 DNA was detected by nested-PCR in PBL of one cow with clinical signs and nasal (1/7)-conjunctival(1/9) swab samples of two sheep housed in the same barn. According to the sequence analysis, three slightly divergent viruses were detected. The results indicate the need for additional research in different regions of Turkey to gain a better understanding of the incidence of MCF and its implications for the livestock industry.

Abstract
Five BVDV species 2 (BVDV-2) isolates were detected from cattle in Turkey. Phylogenetic analysis was performed based on the 5' untranslated regions (UTRs) and E2 coding gene regions, respectively. The isolates were closely related to BVDV-2a strains from North America and Canada used as references. This is the first report of the detection of BVDV-2 in naturally infected Turkish cattle. It is important to consider BVDV-2 for planning future BVDV control and vaccination programs in Turkey.

Abstract
OBJECTIVES To investigate the role of shared epitope (SE) alleles in the short-term clinical response to leflunomide for the treatment of active RA. METHODS In an open-label, multi-centre study of 16-weeks duration, 93 patients (82% female) fulfilling ARA 1987 RA criteria were treated with leflunomide (100 mg loading dose for 3 days, then 20 mg/day as the maintenance dose). The primary efficacy criterion was the response status according to the European League Against Rheumatism (EULAR) response criteria using Disease Activity Score-28 (DAS28) activity measure. SE determinations have been undertaken by polymerase chain reaction and sequence-specific oligonucleotide genotyping methods. RESULTS The mean (s.d.) Disease Activity Score-28 (DAS28) was 5.1 (1.3) before the treatment, which was significantly decreased after 16 weeks [3.0 (1.1), P < 0.001]. According to the EULAR response criteria, 55 patients (59.1%) were classified as good responders. SE was positive in 51 (54.8%) of the patients, with 13 (13.9%) having SE homozygosity or carrying any two SE alleles. Among SE-positive patients, 68.6% (35/51) were good responders, compared with 47.6% (20/42) in SE negatives (P = 0.04). No difference was present according to SE hetero- or homozygosity (68.4 vs 69.2%). RF was also present significantly more frequently in the SE-positive group compared with negatives (78.4 vs 57.1%, P = 0.03). However, no significant difference was observed in the prevalence of RF positivity in patients with a good clinical response (72.7 vs 63.2%, P = 0.32). CONCLUSIONS The results suggest that HLA-DRB1 SE presence may favourably affect the outcome of leflunomide monotherapy in an unselected group of RA patients with an active disease and naive to leflunomide.

Abstract
We compared 65 anti-acetylcholine receptor (AChR)-negative myasthenia gravis (MG) patients, including 32 anti-muscle-specific tyrosine kinase (MuSK)-positive (49%) and 33 anti-MuSK-negative (seronegative) (51%) patients, with 161 anti-AChR-positive MG patients. The anti-MuSK-positive group had a higher frequency of bulbar involvement and respiratory crises. The seronegative group was in between the anti-MuSK positive and the anti-AChR positive groups, being closer to the latter, with regard to the severity of the disease. At the end of follow-up, the outcome of the anti-MuSK-positive patients was not different from that of the anti-AChR-positive patients, although their maintenance corticosteroid dose was higher. The seronegative patients had better outcome than the other two groups.

Abstract
Takayasu's arteritis (TA) is a chronic arterial inflammation of unknown etiology involving mainly the aorta and its major branches. Genetic polymorphisms of cytokines are screened as susceptibility factors for TA in Turkey. A total of 94 patients with TA were investigated for the genetic polymorphisms of the interleukin genes IL12, IL2,and IL6 and were compared with 108 healthy control subjects using polymerase chain reaction-sequence-specific primer method. The frequencies of IL12B 1188 C allele (p = 0.03, OR = 1.7) and CC genotype (p = 0.007, OR = 3.7) were both higher in TA patients than in control subjects. TT genotype at IL2-330 (p = 0.006, OR = 2.4) and GG genotype at IL6-174 (p = 0.04, OR = 1.9) were more frequent in TA patients. Lower prevalence of GT genotype at IL2-330 (p = 0.005, OR = 0.4), CG genotype at IL6-174 (p = 0.001, OR = 0.4), and AG genotypes at IL6-598 (p = 0.01, OR = 0.4) were also detected. The polymorphism of IL-12 as well as IL-6 and IL-2 genes may contribute to susceptibility and pathogenesis of TA by altering cytokine production and inducing inflammation.

Abstract
In this study, the sera collected from a variety of mammalian species (ass-mules, cat, cattle, dog, horse, human and sheep) in 10 representative provinces of Turkey, were surveyed for the presence of neutralizing antibodies to West Nile virus (WNV). Overall, 1 of 40 (2.5%) ass-mules, 4 of 100 (4%) cattle, 43 of 114 (37.7%) dogs, 35 of 259 (13.5%) horses, 18 of 88 (20.4%) humans and 1 of 100 (1%) sheep, tested positive for WNV-neutralizing antibodies. The results indicate that a wide range of mammals are exposed to a West Nile-related virus and this could contribute to the long-term survival of this virus in the absence of overt disease.

Abstract
OBJECTIVE In order to determine the significance of proliferative activity (PA) in endometrial carcinomas, we analysed the expression of cell cycle-related antigens in routinely processed tissue. MATERIALS AND METHODS Serial sections of 113 endometrial carcinoma specimens were immunostained with the monoclonal antibody DNA Topoisomerase II-alpha (Ki-S1). In addition to Topoisomerase II-alpha (Ki-S1) staining, histologic type, International Federation of Gynecology and Obstetrics (FIGO) stage. FIMO grade, depth of myometrial invasion, tumor size, lymphovascular space invasion, serosal and/or adnexal involvement, lymph node metastasis, age and peritoneal cytology were evaluated as prognostic indicators. The median follow-up time was 23 (range, 1 to 126 ) months. RESULTS FIGO stage, FIGO grade, tumor size, lymphovascular space invasion, lymph node metastasis, peritoneal cytology and Topoisomerase II-alpha (Ki-S1) expression all significantly influenced survival in univariate analyses (p < or = 0.05). In the Cox regression analysis, Topoisomerase II-alpha (Ki-S1), serosal and/or adnexal involvement, and lymph node metastasis expression were the only variables with independent prognostic impact (p < or = 0.05), whereas FIGO stage, FIGO grade, histologic type FIGO grade, depth of invasion, tumor size, lymphovascular space invasion, age and peritoneal cytology had no independent influence (p > 0.05). Topoisomerase II-alpha (Ki-S1) staining was significantly elevated in advanced (Stage II, III, IV) as opposed to early (Stage I) carcinomas (p < or = 0.05). CONCLUSION The association with established prognosticators for endometrial carcinomas, and the results of uni- and multivariate analysis indicate that the additional evaluation of DNA Topoisomerase II-alpha (Ki-S1) peptide antibody (PA) is useful for classifying patients into subgroups with low and high risk of relapse which might help to individualize the therapeutic strategy in endometrial carcinomas.

Abstract
BACKGROUND Multidrug-resistant pulmonary tuberculosis (MDRTB), a major problem in developing countries, may result from either insufficiency of host cellular immune response or mycobacterial mechanisms which has been more intensively investigated so far. OBJECTIVES The aim of the study was to investigate natural killer cell activity (NKA) and T lymphocyte subsets in HIV- patients with secondary MDRTB. METHODS 20 male patients with MDRTB (mean age 38 +/- 8 years), 15 nonresistant tuberculosis male patients (NRTB) (mean age 36 +/- 11 years) and 12 healthy male controls (mean age 35 +/- 8 years) were included. The percentages of CD3+, CD4+, CD8+, CD25+, CD11b+ and CD16+56+ cells were measured by flow-cytometric analysis of peripheral blood lymphocytes (PBL). NKA was evaluated using the anticandidal index method. RESULTS The mean tuberculin response was higher in MDRTB and NRTB patients compared to controls (15.4 +/- 3.8, 15.1 +/- 3.3 and 10.9 +/- 2.8 mm, respectively; p < 0.001). There was no significant correlation between PPD response and PBL subsets or NKA. The percentages of both CD3+ and CD3+CD4+ T lymphocytes were significantly lower in MDRTB (62.4 +/- 12.1 and 33.9 +/- 9.0%) compared to NRTB (70.8 +/- 7.5 and 42.9 +/- 8.6%; p < 0.05). Patients with MDRTB had significantly lower NKA compared to NRTB and controls (30.9 +/- 11.3, 49.7 +/- 15.5 and 40.0 +/- 8.5%, respectively; p < 0.01). CONCLUSION This reduction in NKA may suggest a role for impaired NK function in the pathogenesis of MDRTB in HIV- patients.

Abstract
The penetration of oral 1000 mg/day ciprofloxacin into pleural fluid is investigated in 15 patients with exudative pleural effusion. After 4 days of ciprofloxacin therapy ciprofloxacin concentrations were measured in plasma and pleural exudate simultaneously by high-performance liquid chromatography (HPLC). Mean serum ciprofloxacin level was 1.58 +/- 0.91 mg/L and mean pleural exudate concentration was 1.00 +/- 0.59 mg/L. The concentrations achieved were all above the MIC90 of the majority of Gram-positive and Gram-negative pathogens. It is concluded that ciprofloxacin penetrates well into the pleural fluid.
