Ectopic mediastinal parathyroid adenomas are rare, but can be life-threatening. Resection is indicated in those cases accompanied by hypercalcemia, especially in young patients. Although most mediastinal parathyroid adenomas can be removed by a cervical approach, a transthoracic approach is needed when the adenoid tissues are located deep within the thoracic cavity. We describe the case of a 37-year-old female who underwent excision of an intrathoracic ectopic parathyroid adenoma after parathyroidectomy four months earlier.

The most common cause of primary hyperparathyroidism is a single adenoma accounts for more than 85% and about 1-2% in multiple occurrence. The adenoma arises mainly in the neck and rarely in the mediastinum. The simultaneous occurrence is extremely rare. A 73-year-old man came to our clinic complained about sense of falling forward during last eight months. The brain MRI and vestibular function test showed non-specific findings but total calcium and intact parathyroid hormone levels were markedly elevated. Radiologic studies and sesta-MIBI scan revealed multiple masses in lower paratracheal area and superior mediastinum. We performed mass excision with transcervical approach and all of them were diagnosed as parathyroid adenoma. After surgery, intact PTH and calcium levels returned to the normal range and his symptoms were dramatically improved. We report the unique and rare disease entity with a brief literature review.

Lawsonia intracellularis is the pathogenic agent of porcine proliferative enteritis (PPE). The bacterial pathogen infects the intestinal crypt cells which causes hyperplasia of the infected cells and leads to the process of intestinal pathogenesis. PPE includes some clinical maninfestations, including acute hemorrhagic diarrhea with sudden death in growing pigs and porcine intestinal adenomatosis, to a chronic diarrhea with reduced productivity of the infected pigs. The purpose of the present studies were carried out to determine L. intracellularis in livestock transport car of slaughterhouse. Distribution of L. intracellularis in livestock transport car were conducted using real-time polymerase chain reaction (real-time PCR) testing method, total 300 samples. Of 300 samples, 119 (39.7%) were detected as positive to L. intracellularis in livestock transport car. In seasonal analysis, 42 (28.0%) out of 150 samples in spring and summer season. 77 (51.3%) out of 150 sample in autumn and winter season. In regional analysis, 53 (88.3%) out of 60 cars and the detection ratio showed that regional variation in livestock transport car.
