A clinical comparison of budesonide nasal aerosol, terfenadine and a combined therapy of budesonide and oxymetazoline in adult patients with perennial rhinitis.

The efficacy of budesonide, terfenadine and a combination of budesonide and oxymetazoline in the treatment of perennial rhinitis was evaluated by a double blind, parallel group study. Adult patients with perennial rhinitis were randomized into three groups. Group 1 patients received budesonide nasal aerosol 400 micrograms/day for 21 days and oxymetazoline nasal drops for the first three days. Group 2 and 3 patients received budesonide 400 micrograms/day and terfenadne tablet 60 mg twice/day respectively. Nasal symptoms were assessed by the patients before and daily during the treatment period using a simple scoring system. One hundred and forty-two patients were recruited and 130 completed the study. Budesonide, but not terfenadine, significantly reduced all nasal symptoms from baseline (p less than 0.05). Terfenadine could significantly relieve the nasal blockage (p less than 0.05) more than other nasal symptoms. Budesonide with or without oxymetazoline nasal drops provided a better control of nasal symptoms than terfenadine (p less than 0.05). Budesonide with oxymetazoline for the first three days showed a faster relief of nasal blockage than budesonide alone (p less than 0.05). Mild and transient adverse effects were encountered in all three groups. It is concluded that nasal symptoms of perennial rhinitis are more adequately controlled by budesonide than by terfenadine.

Efficacy of fine needle aspiration cytology in the diagnosis of tuberculous cervical lymphadenopathy.

The results of a consecutive series of 1,349 fine needle aspiration (FNA) biopsies from the head and neck region of 1,193 patients has been reviewed in order to evaluate the efficacy of this method in the diagnosis of tuberculous lymphadenopathy (TBLN). Of the 108 patients whose fine needle aspiration cytology (FNAC) showed granulomatous changes, 68 had subsequent surgery and histological confirmation of the cytological appearance. Sixty-three had TBLN, thus the specificity of FNAC was 93 per cent in diagnosing tuberculous related granulomatous lymphadenopathy. One false positive FNAC was reported histologically to be metastatic mucoepidermal carcinoma. Of the 1,193 patients, 90 patients had subsequently TBLN confirmed histologically. Of these 90 patients, FNA from 69 showed granulomatous changes or acid fast bacilli (AFB), thus the sensitivity of FNAC in detecting tuberculous lymphadenopathy was 77 per cent. Fifty-two cytological smears were stained for acid fast bacilli. Nineteen (37 per cent) contained AFB. It is evident from this review that FNAC is an efficient way to detect cervical tuberculous lymphadenopathy.

Brainstem auditory evoked potentials after irradiation of nasopharyngeal carcinoma--report on two cases with myelopathy of the brainstem.

Brainstem auditory evoked potentials (BAEP) were recorded in two patients with nasopharyngeal carcinoma (NPC) irradiated 14 and three years ago respectively and compared with 15 healthy controls. The patients had features of post-irradiation myelopathy of the brainstem with reduced gag reflex, unilateral vocal cord paralysis and fasciculation of the tongue. The first patient had a blind left eye. The second patient had quadriparesis. All ears revealed post-irradiation otitis media changes and mixed deafness. BAEP was not recognizable in the left ear of the first patient and was normal in the left ear of the second patient. Simultaneous electrocochleogram and BAEP were recorded from the right ear of the first case. The wave I-V latency interval were prolonged in both right ears. In the absence of local recurrence and brain secondaries, these BAEP changes are attributed to the post-irradiation myelopathy of brainstem.

Fine needle aspiration biopsy of tuberculous cervical lymphadenopathy.

Fine needle aspiration biopsies of 42 histologically confirmed tuberculous cervical lesions were studied. Thirty-four patients had subsequent excision of cervical lymph nodes and eight had incision and drainage of cervical abscesses. All aspirates except two (which were inadequate) were satisfactory for diagnosis and contained inflammatory cells. Twenty-seven smears revealed cells typical of granulomatous lymphadenopathy, that is, epithelioid and multinucleated giant cells. Of all aspirates, 17 smears had bacteriological staining by Ziehl-Nielsen technique, nine of which (53%) were positive for acid-fast bacilli. An aspiration biopsy diagnosis of granulomatous or tuberculous cervical lymphadenopathy was made in 30 patients (71%). In regions where mycobacterial infection is common, the presence of granulomatous changes in lymph node aspirates is highly suggestive of tuberculosis. When the aspirates contain purulent material or when tuberculosis is suspected, staining and culture for mycobacteria should be performed. FNA biopsy is a sensitive, specific and cost-effective way to diagnose tuberculous cervical lymphadenopathy and is recommended.

The efficacy of myringotomy and ventilation tube insertion in middle-ear effusions in patients with nasopharyngeal carcinoma.

Myringotomy and insertion of a grommet are effective in the management of middle-ear effusion resulting from nasopharyngeal carcinoma. The procedure was carried out in 46 ears in 30 patients, resulting in significant improvement of hearing. The complication rate of the operative procedure is not negligible in this group of patients, and it is higher if the patients had received radiotherapy at the time of operation.

An unusual laryngeal foreign body in an infant.

A case is presented of laryngeal impaction in an infant by a cervical vertebra of a toad. Symptoms were mild initially but became progressive later with secondary laryngeal edema. Early diagnosis was not made, which resulted in considerable difficulty in management. Computerized tomography (CT) scan was found to be useful in identifying the foreign body and thereby facilitating management. CT is recommended for suspected foreign bodies in the air and food passages where more conventional methods fail to make a diagnosis.
