Follow-up examinations of one hundred persons treated with x-rays for tuberculous adenitis between 1930 and 1946 have been carried out to determine if there is an increased incidence of hyperparathyroidism (HPT) after radiation exposure. Neck explorations were done in patients with hypercalcemia and signs and symptoms compatible with HPT. Individuals with thyroid masses were also operated upon when examination of fine needle specimens gave suspicions of malignancy. Eleven subjects were found to have developed parathyroid adenoma or hyperplasia. Four other individuals have hypercalcaemia but are asymptomatic. The mean absorbed dose in the parthyroid glands varied between 75 and 2,200 rads. Six individuals received more than 1,200 rads; four of them later developed HPT, while no HPT occurred below a dose of 300 rads. The high incidence of HPT among patients who had been heavily exposed to radiation suggests a cause and effect relationship between radiation treatment and development of HPT.

Between 1987 and 1992, one surgeon performed 242 parotidectomies in 229 patients. Among 97 patients with benign disease, pleomorphic adenoma (46) and sialo-adenitis (28) predominated, while metastatic melanoma (22) and squamous cell carcinoma (21) were the most common diagnoses among 132 patients with malignancy. The extent of parotidectomies were: 114 'appropriate' resections, 77 complete superficial parotidectomies, 35 near-total conservative and 14 radical total resections. The facial nerve was sacrificed in 19 operations and reconstructed in four. One hundred and five patients had a concomitant neck dissection and 45 patients had adjuvant radiotherapy. Postoperative facial nerve function was normal in 90% of patients with localized tumours and 55% of patients overall. Patients with sialo-adenitis or deep lobe tumours and those having a neck dissection were at greatest risk of facial weakness despite nerve preservation. At a median follow up of 34 months, 13 patients had developed tumour recurrence and attempts at salvage surgery have generally been disappointing.

Transbronchial needle aspiration (TBNA) is a bronchoscopic technique to obtain cytologic and histologic specimen from deep site of bronchial wall. We investigated the utility and safety of TBNA in 200 patients who had mass lesions in the lung or in the mediastinum. 101 patients had submucosal or peribronchial malignant lesions (central malignancy) and TBNA was the only diagnostic method in 28 patients (28%). 39 patients had peripheral malignant lesions (peripheral malignancy) and TBNA was the only diagnostic method in 12 patients (31%). The other 60 patients had benign lesions and TBNA was diagnostic in only 5 patients (8%); bronchogenic cyst in 2, tuberculous lymph adenitis in 1, parathyroid adenoma in 1 and lung abscess in 1. In central malignancy, the yield of TBNA as exclusive means of diagnosis was higher for mediastinal tumor than for lung cancer. In peripheral malignancy it was higher for metastatic lung tumor than for primary lung tumor. In order to stage patients of lung cancer, we sampled 39 lymph nodes and 21 of them were proved to be positive. TBNA was thought to be of greatest value in the diagnosis of peritracheal mediastinal tumor and peribronchial metastatic lung tumor and in the staging of lung cancer. We used 19-gauge transbronchial histology needle in 8 patients and 2 cases were diagnostic. Low diagnostic yields were probably due to the lack of our experience and it was expected that training on this technique would increase diagnostic utility of the histology needle. No significant complications occurred and all patients tolerated TBNA well.

A 53-yr-old male captive mata mata turtle (Chelus fimbriatus) was examined following sudden death. The animal was in good nutritional, muscular and postmortem condition. The esophageal wall was circumferentially expanded by a discrete, oblong, irregular, tan, and soft contiguous glandlike structure. Histologically, the mass comprised uneven, sometimes cavitated islands of polygonal neoplastic cells consistent with an esophageal adenocarcinoma. In addition, peripheral to the mass, there was glandular epithelial hyperplasia, dysplasia, and multifocal heterophilic and lymphohistiocytic adenitis. Neoplastic cells expressed pancytokeratins; however, they demonstrated no immunoreactivity to vimentin, chromogranin, synaptophysin, and thyroglobulin. Additional findings included multifocal to coalescing areas of cortical fibrosis and membranous glomerulonephritis affecting both kidneys, and a focal hepatocellular adenoma.
