Tularemia, a reemerging disease in northwest Turkey: epidemiological investigation and evaluation of treatment responses.

An outbreak of tularemia occurred in three provinces in Turkey in February 2004 and reemerged in the same provinces in February 2005. A total of 61 cases, 54 of which were confirmed with the micro-agglutination test, were diagnosed with oropharyngeal tularemia. No culture for Francisella tularensis was attempted, but PCR for F. tularensis was positive in aspiration material of suppurated lymphadenitis of 7 patients. F. tularensis detection with PCR was negative in water samples, but epidemiologic and environmental findings suggested that contaminated water or food was the cause of the outbreaks. Late initiation antibiotic therapy could not prevent suppuration and draining of the involved lymph nodes.

[Long-term results of radiofrequency-assisted posterior transverse cordotomy in a rabbit model].

OBJECTIVES: We evaluated the long-term results of radiofrequency-assisted posterior transverse cordotomy in a rabbit model. STUDY DESIGN: Ten healthy New Zealand rabbits were subjected to videolaryngoscopic examination following intraperitoneal anesthesia with 20 mg/kg thiopental. After local infiltration anesthesia with lidocaine, a laryngofissure procedure and exposition of the vocal cords were carried out and posterior transverse cordotomy was performed to the right vocal cord in the cutting mode using radiofrequency waves (Ellman Surgitron). The thyroid cartilage was closed in anatomic position and the rabbits were followed-up for three months, after which videolaryngoscopic examination was repeated. The rabbits were then sacrificed for histopathologic examination. RESULTS: At the end of the follow-up period, videolaryngoscopic examination showed neo-cordogenesis in the right vocal cord region. Histological examination showed closure of the operation site by granulation tissue and fibrosis. CONCLUSION: The opening created in the rabbit larynx using radiofrequency was filled by granulation tissue and fibrosis in the long-term.

Three-dimensional CT of Eagle's syndrome.

This case report presents three-dimensional computed tomography (3D-CT) findings in the diagnosis of Eagle's syndrome that is characterized with an elongated styloid process or a calcified stylohyoid ligament causing craniofacial or cervical pain. We have performed 3D-CT in three patients suspected to have this condition. Coronal images were taken in two patients and axial images in one patient with a spiral CT scanner. 3D-CT images were then produced. The length of the styloid process in the case suspected of right elongated styloid process was 45.6 mm (left styloid process, 37 mm). In the second case suspected of left elongated styloid process, the length of the left styloid process was 41.1 mm (right styloid process, 40.2 mm). In the last case suspected of right elongated styloid process, the length of the right styloid process was 40.6 mm (left styloid process, 38.9 mm). 3D-CT is a valuable diagnostic tool in the diagnosis of Eagle's syndrome because of its ability to facilitate accurate measurement of the length of the styloid process.

Thyroid hemiagenesis: a case report.

Thyroid hemiagenesis is usually diagnosed incidentally during examination for other thyroid gland diseases. Iodine-123 thyroid scan of a 25-year-old woman showed a normal homogeneous right thyroid lobe, but no uptake in the left lobe. Ultrasonography of the neck confirmed the absence of the left thyroid lobe, while the right lobe was homogeneous and normal. Thyroid hemiagenesis should be included in the differential diagnosis of thyroid diseases.
