Tuberculous deep neck infection in a soldier, preceding miliary tuberculosis: a diagnostic dilemma.
Tuberculosis can affect every organ, most importantly the lungs, and worldwide it is the leading cause of death attributable to a single infectious agent. Tuberculous involvement of the neck is also possible. Patients mostly present with masses or draining fistulas in the neck, which are mostly located in the posterior cervical, submandibular, and supraclavicular regions. We report on a soldier who presented with a tuberculous deep neck infection, followed by miliary tuberculosis. The clinical presentation and diagnostic dilemmas are discussed.

Mycobacterial cervical lymphadenitis.
Cervical lymphadenitis is the most common head and neck manifestation of mycobacterial infections. The incidence of mycobacterial cervical lymphadenitis has increased. It may be the manifestation of a systemic tuberculous disease or a unique clinical entity localized to neck. It remains a diagnostic and therapeutic challenge because it mimics other pathologic processes and yields inconsistent physical and laboratory findings. A high index of suspicion is needed for the diagnosis of mycobacterial cervical lymphadenitis. A unilateral single or multiple painless lump, mostly located in posterior cervical or supraclavicular region can occur. A thorough history and physical examination, tuberculin test, staining for acid-fast bacilli, radiologic examination, fine-needle aspiration and PCR will be instrumental in arriving at an early diagnosis early institution of treatment before a final diagnosis can be made by biopsy and culture. It is important to differentiate tuberculous from nontuberculous mycobacterial cervical lymphadenitis because their treatment protocols are different. Tuberculous adenitis is best treated as a systemic disease with antituberculosis medication. Atypical infections can be addressed as local infections and are amenable to surgical therapy.

Brucellosis of the spine: evaluation of the clinical, laboratory, and radiological findings of 14 patients.
In this study, we aimed to assess the clinical, laboratory and radiological findings of vertebral involvement in brucellosis. Fourteen patients diagnosed with spondylitis and spondylodiscitis due to brucellosis were included in the study. Computed tomography, magnetic resonance imaging, or scintigraphy were used to diagnose the vertebral involvement. The control group consisted of 20 patients with brucellosis but no vertebral involvement. The clinical, laboratory, and radiological findings of both groups were compared. The prevalence of vertebra involvement in brucellosis was found to be 7.5%. Of the 14 study patients, two had thoracic, ten had lumbar, and two had both lumbar and sacral vertebral involvement. The associated pathologies were spondylodiscitis, narrowing in the intervertebral space, inflammation or abscess formation in the paravertebral soft tissue, and osteophyte formation. None of the patients had a collapsed vertebral body, angulation deformity, or inflammation in the epidural space. In conclusion, the possibility of vertebral involvement should be remembered in chronic brucellosis, particularly in elderly patients who present with back pain or tenderness over the spine. A high index of suspicion and clinical, laboratory, and radiological examinations help confirm the diagnosis of vertebral involvement.

Histopathologic assessment of fungal involvement of the paranasal sinuses in Turkey.
OBJECTIVE: To assess paranasal sinus material histopathologically for the presence of fungus. MATERIAL AND METHODS: Paraffin-embedded archival biopsy samples of patients who underwent endonasal sinus surgery between 1992 and 2002 were retrospectively assessed for the presence of fungi. Hematoxylin-eosin-stained sections of the materials were re-evaluated, and Gomori's methanamine silver stain was also applied as required. RESULTS: Fungus (Aspergillus) was detected histopathologically in only 21476 patients, both of whom were immunocompetent. One patient was considered to have chronic indolent sinusitis and the other allergic fungal sinusitis. CONCLUSIONS: Although histopathologic assessment is one of the most important diagnostic tools, on its own it may lead to underestimation of fungal involvement of the paranasal sinuses. Alternatively, fungal involvement of the paranasal sinuses may be very infrequent in Turkey.

Evaluation of a polymerase chain reaction amplification method for Mycobacterium tuberculosis complex on samples from different sources.
Using primers specific for the IS6110 region of Mycobacterium tuberculosis complex, successful amplification by the polymerase chain reaction was demonstrated in 81 of 84 archive specimens from patients who had been clinically diagnosed 2 months to 16 y previously as having tuberculosis. Depending on the time of storage of the specimens, extra DNA bands were found in addition to the IS6110 region band.

Serum cytokine levels in Bell's palsy.
OBJECTIVE: To assess the significance of the serum levels of the cytokines (interleukine (IL-6, IL-8, IL-1b, IL-2r, and tumor necrosis factor alpha (TNF - alpha)) in the patients with Bell's palsy. STUDY DESIGN: A clinical and laboratory study in which serum cytokine levels were compared between the patients who had Bell's palsy and healthy controls. METHODS: Twenty-three patients with Bell's palsy and 30 healthy volunteers were included in the study. The blood samples of the patients and controls were obtained, and serum IL-1b, IL-2r, IL-6, IL-8, and TNF- alpha levels determined with chemiluminescence enzyme immunometric assay on an Immulite Immunoassay. The serum of the patients was taken between 2 days and 1 month after the disease. The assay was not in vitro lymphocyte stimulation. RESULTS: The IL-6, IL-8 and TNF- alpha levels were significantly higher in Bell's palsy than in controls (p < 0.05). The IL-1b and IL-2r levels were similar in both groups (p > 0.05). The levels of cytokine IL-6, IL-8, TNF- alpha, IL-1b, IL-2r did not correlate with the degree of recovery (p > 0.05). CONCLUSION: An alteration in the concentration of the cytokines is expected not only in many inflammatory and infectious diseases but also in Bell's palsy. Cytokines are not stored or preformed within cells. Therefore, high cytokine levels (IL-6 and IL-8, and TNF- alpha) should represent their production in response to underlying pathology in Bell's palsy, or these cytokines may be pathogenetic factors in Bell's palsy. However, serum levels of these cytokines do not help determine the prognosis in Bell's palsy as far as the results of this study are concerned.

Hearing status in brucellosis.
BACKGROUND: Although brucellosis can lead to multisystem complications, involvement of the ear in brucellosis is rarely reported in the literature. The purpose of this study was to assess the hearing status of patients with brucellosis. STUDY DESIGN: Thirty-two patients with brucellosis were included in the study. Pure tone and speech audiometry and tympanometry were performed in the patients. RESULTS: The mean pure tone averages of the patients were within normal limits and were similar in both ears (P > 0.05). The pure tone averages of the patients with or without anti-Brucella treatment were not significantly different (P > 0.05) and were within the normal limits. When the hearing levels of these patients were compared at the frequencies of 250, 500, 1000, 2000, 4000, and 8000 Hz, there was no significant difference as well (P > 0.05). CONCLUSIONS: Peripheral brucellosis does not appear to be associated with hearing loss.
