In this multicentre study, which is the largest case series ever reported, we aimed to describe the features of tularaemia to provide detailed information. We retrospectively included 1034 patients from 41 medical centres. Before the definite diagnosis of tularaemia, tonsillitis (n = 653, 63%) and/or pharyngitis (n = 146, 14%) were the most frequent preliminary diagnoses. The most frequent clinical presentations were oropharyngeal (n = 832, 85.3%), glandular (n = 136, 13.1%) and oculoglandular (n = 105, 10.1%) forms. In 987 patients (95.5%), the lymph nodes were reported to be enlarged, most frequently at the cervical chain jugular (n = 599, 58%), submandibular (n = 401, 39%), and periauricular (n = 55, 5%). Ultrasound imaging showed hyperechoic and hypoechoic patterns (59% and 25%, respectively). Granulomatous inflammation was the most frequent histological finding (56%). The patients were previously given antibiotics for 1176 episodes, mostly with β-lactam/β-lactamase inhibitors (n = 793, 76%). Antituberculosis medications were provided in seven (2%) cases. The patients were given rational antibiotics for tularaemia after the start of symptoms, with a mean of 26.8 ± 37.5 days. Treatment failure was considered to have occurred in 495 patients (48%). The most frequent reasons for failure were the production of suppuration in the lymph nodes after the start of treatment (n = 426, 86.1%), the formation of new lymphadenomegalies under treatment (n = 146, 29.5%), and persisting complaints despite 2 weeks of treatment (n = 77, 15.6%). Fine-needle aspiration was performed in 521 patients (50%) as the most frequent drainage method. In conclusion, tularaemia is a long-lasting but curable disease in this part of the world. However, the treatment strategy still needs optimization.

Brucellosis is the most common anthropozoonosis, with more than 500,000 cases annually. While the disease was eradicated in the vast majority of industrialized regions around the world, it remains a significant public health concern, mainly in the Mediterranean littoral, the Middle East, the Arabian Peninsula, the Indian subcontinent, Asia, Africa, and Central and South America (19,26).Turkey is a relatively large country in the eastern Mediterranean region, with a geographical surface of 783,562 km 2 , and comprises seven regions. It has a population of 72 million, 70% of which lives in cities and 30% in rural areas. Brucellosis is endemic, and approximately 10,000 human brucellosis cases are reported annually. The reported incidence is 150 cases per 1 million inhabitants (24). Its prevalence varies widely from region to region due to several factors, including food habits, milk processing methods, husbandry practices, nomadism, social customs, climatic conditions, socioeconomic status, and environmental conditions. A steady increase of reported human cases was observed from 1986 (3.03/100,000 population) until 2004 (25.65/100,000). Livestock vaccination, elimination of infected animals, control of animal movements, and education induced a decline in the number of annually reported human cases, from 18,563 cases in 2004 to 9,818 cases in 2008 (17).Rapid and accurate typing procedures are crucial for epidemiologic surveillance, investigation of outbreaks, and follow-up of a control program. Many molecular typing methods commonly used for the subtyping of isolates of other bacterial species are not appropriate for routine typing of Brucella strains, and none has proven to be fully satisfactory for epidemiological trace-back investigations of brucellosis (1,9,25). Recently, a selection of 16 variable-number tandem repeats has been proposed for fingerprinting Brucella isolates (7,14,25). This multiple-locus variable-number tandem-repeat analysis (MLVA) genotyping system, MLVA-16 Orsay , comprised eight minisatellite markers (panel 1, Bruce06, Bruce08, Bruce11, Bruce12, Bruce42, Bruce43, Bruce45, and Bruce55) for species identification and eight complementary microsatellite markers (panel 2A, Bruce18, Bruce19, and Bruce21; panel

Brucellosis is a common zoonosis which still remains as a major health problem in certain parts of the world. Osteoarticular involvement is the most frequent complication of brucellosis, in which the diagnosis of brucellar spondylodiscitis is often difficult since the clinical presentation may be obscured by many other conditions. Herein, we reported an uncommon case of spondylodiscitis due to brucella in an elderly male who had diabetes mellitus and degenerative spinal disease as underlying conditions. The diagnosis was established by using magnetic resonance imaging after the brucella-agglutination test was found to be positive. The diagnosis was also confirmed by positive blood culture. A high degree of suspicion in the diagnosis of brucellar spondylitis is essential to reduce the delay for the treatment. Thus, it should be essentially included in the differential diagnosis of longstanding back pain particularly in regions where brucellosis is endemic. Screening serologic tests for brucella should be used more widely in cases with low index of suspicion, especially in endemic areas.

Serum levels of proinflammatory cytokines, interleukin-1 beta (IL-1beta), tumor necrosis factor alpha, (TNF-alpha), and their inhibitors, IL-1 receptor antagonist (IL-1ra) and soluble TNF receptor 1 (sTNFR1), were determined by enzyme-linked immunosorbent assay in 104 patients with Behçet's disease (65 active, 39 inactive) and 40 healthy controls. The levels of IL-1beta and IL-1ra were significantly higher in both active and inactive patients than in control subjects (P<0.01 and P< 0.01, respectively). The concentrations of TNF-alpha and sTNFR1 were found to be higher in active patients than in controls (P< 0.01 and P< 0.001, respectively). There were no significant differences in the serum levels of these cytokines and their inhibitors between active and inactive patients. Significant increases in mean C-reactive protein level and erythrocyte sedimentation rate were found in patients with active vs inactive disease (P< 0.001 and P< 0.05, respectively). C-reactive protein values correlated with erythrocyte sedimentation rate but not with cytokines or their inhibitors. Our conclusion is that elevated serum TNF-alpha and sTNFR1 seem to be important inflammatory mediators in Behcet's disease. The statistically significant increase in these levels may arise from the severity of inflammation in the tissue or organ involved.

Background: Doxycycline is the most effective antibiotic for managing brucellosis. Although it is relatively free from side effects, complications involving the skin, nails and teeth may rarely be encountered. Methods: Four patients with brucellosis developed yellow-brown discolouration of teeth following a 30-45 day course of doxycycline therapy during summer at a dose of 200mg/day. Results: All four patients were diagnosed as having doxycycline-induced staining of the permanent dentition. In all cases, the staining completely resolved and the teeth recovered their original colour following abrasive dental cleaning. Conclusions: These observations indicate that the incidence of staining of the permanent dentition, as a complication of doxycycline, may be much higher than the literature indicates, especially if treatment is administered during summer months. Fortunately, this complication is reversible and does not require termination of doxycycline therapy. Complete resolution following abrasive cleaning may suggest that an extrinsic mechanism within the dental milieu may be involved in its pathogenesis. Strict avoidance of sunlight exposure during high-dose, long-term doxycycline therapy might prevent the development of this complication.

The genotyping findings of the present study do not support a role for the CD14-159C/T polymorphism in the development of tuberculosis, at least in the geographical region of central Anatolia. Significantly elevated serum sCD14 levels in patients with active disease reflect the importance of the mononuclear phagocytic system activation in tuberculosis.

Brucellosis is a systemic infectious disease with a broad spectrum of clinical manifestations. Arthritis is frequently observed in its course and may be one of the main presenting clinical features of the disease. We report a case of brucellar monoarthritis of the knee with a prolonged clinical course despite efficient antibiotic treatment.
