The issue of fine needle aspiration cytology in the diagnosis of tuberculous cervical lymphadenitis
BackgroundDue to different reports about the value of fine needle aspiration cytology (FNAC) as a simple and minimal invasive diagnostic tool for extra-pulmonary tuberculosis, we attempted to demonstrate the sensitivity of FNAC in patients with cervical tuberculous lymphadenitis in Iran. We wanted to know if fine needle aspiration (FNA) is an accurate method as a first step in diagnosis or not.Methods This study covered a 14 year period identifying 137 patients with a pathological report of granulomatosis in excisional biopsy of lymphadenopathy in two tertiary referral hospitals of Tehran, Iran. The results of fine needle aspiration cytology (FNAC) in 67 patients with tuberculosis cervical lymphadenitis were evaluated. Results The FNA cytology showed granuloma with background necrosis in five patients (7.46 per cent) and granuloma with or without necrosis in 13 patients (19.40 per cent). Patients with positive results of FNAC had a longer duration of lymphadenopathy compared to other patients.ConclusionIn this study, sensitivity of FNAC was reported to be low. The sensitivity of this method was 7.46 per cent (including pathology granuloma with background necrosis) and 19.40 per cent (total cases of granuloma with or without necrosis). It seems that the sensitivity of FNAC is significantly lower in patients with early cervical tuberculosis (TB) lymphadenitis. Combining acid-fast bacillus (AFB) staining and non-culture methods like polymerase chain reaction (PCR) could increase FNA sensitivity in these patients
Firework-related injuries in Tehran's Persian Wednesday Eve Festival (Chaharshanbe Soori)
Background: Fireworks are the leading cause of injuries such as burns and amputations during the Persian Wednesday Eve Festival (Chaharshanbeh Soori). Objectives: This study was designed to explore the age of the high-risk population, the type of fireworks most frequently causing injury, the pattern of injury, and the frequency of permanent disabilities. Methods: This cohort study was performed by Tehran Emergency Medical Services at different medical centers all around Tehran, Iran, in individuals referred due to firework-related injuries during 1 month surrounding the festival in the year 2007. The following information was extracted from the patients' medical records: demographic data, the type of fireworks causing injury, the pattern and severity of the injury, the pre-hospital and hospital care provided for the patient, and the patient's condition at the time of discharge. In addition, information on the severity of the remaining disability was recorded 8 months after the injury. Results: There were 197 patients enrolled in the study with a mean age of 20.94 +/- 11.31 years; the majority of them were male. Fuse-detonated noisemakers and homemade grenades were the most frequent causes of injury. Hand injury was reported in 39.8% of the cases. Amputation and long-term disability were found in 6 and 12 cases, respectively. None of the patients died during the study period. Conclusion: The fireworks used during a Chaharshanbeh Soori ceremony were responsible for a considerable number of injuries to different parts of the body, and some of them led to permanent disabilities.
