Anesthesia for the patients with mediastinal mass may be associated with significant respiratory and cardiovaacular complications due to compression of traeheobronchial trees, the pulmonary artery, heart and superior vena cava The authors present a case of a 6-year-old girl with a large mediastinal tumor located in anterior and superior mediaetinum. Preoperatively, the patient was asymptomatic and anesthesia was induced and maintained uneventfully. Operative finding was that 8 X 14 cm sized hemangioma was extended superiorly over thoracic outlet, posteriorly aorta and SVC, medially pericardium and right hilum and inferiorly right upper lung and pleura. Because difficulties in removal of the hemangioma were expected, exploratory thoracotomy was discontinued. On emergence, as soon as the patient was extubated due to irritability, the patient became cyanotic and was noticed bulging mass on right supraclavicular area, Intubation was attempted and during direct laryngoscopy, anesthesiologist also noticed a bulging mass in right oral cavity. Postoperatively, the patients airway was kept with endotracheal tube, but cyanosis appeared on the face and skin over the chest, but not below the abdomen. Bulging mass on right supraclavicular area, distension of neck vein and conjunctival edema were noticed only when the patient was crying or suctioned. Symptoms improved by deep sedation. We assumed that enlargement of hemangioma due to increased central blood volume occasionally compressed tracheobronchial tree and sup. vena cava when patient was irritable, crying and coughing. On 11th postoperative day, patient was transferred to the another hospital for the better treatment with endotracheal intubation.

An adult beagle dog was presented with a cervical mass detected by palpation and computed tomography. Fine needle aspirates revealed numerous epithelial cells with plasmacytoid appearance and frequent naked nuclei. Histologically, the mass consists of multiple packets of neoplastic cells and extensive areas of necrosis and fibrosis. Neoplastic cells were also found in submandibular lymph nodes. Immunohistochemistry showed that neoplastic cells were positive for calcitonin and negative for thyroglobulin. Based on these findings, the cervical mass was diagnosed as thyroid C-cell carcinoma. Almost one year after the surgical excision, the dog remains healthy without any symptom of recurrence or metastasis.

OBJECTIVE: To investigate whether polymorphism of gene encoding COMT is associated with the risk of endometriosis in Korean women. METHODS: We investigated 136 patients with histopathologically confirmed endometriosis rAFS stage III/IV and 251 control group women who were surgically proven to have no endometriosis. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) of PCR products were done to determine each participant's COMT genotype. RESULTS: The distribution according to NIaIII genetic polymorphisms of COMT were as follows. COMT HH, COMT HL, and COMT LL genotypes were 56.6% (77 women), 34.6% (47 women) and 8.8% (12 women) in the study group and 50.6% (127 women), 39.4% (99 women) and 10.0% (25 women) in the control group. There was no significant difference between the study group and the control group. CONCLUSION: The results suggest that COMT genetic polymorphism may not be associated with the development of endometriosis in Korean women.

Innervation anomalies are well-known sources of erroneous interpretation in motor nerve conduction studies. The extensor digitorum brevis (EDB) muscle is supplied by the deep peroneal nerve and is commonly used as recording point in peroneal motor conduction study. If the compound muscle action potentials (CMAPs) are not evoked with EDB muscle recording without any symptoms or signs of peroneal neuropathy, we should lead one to consider either technical pitfall or anomalous innervation. We experienced an anomalous innervation in a woman in whom the bilateral EDB muscles were innervated exclusively by the tibial nerve. This was proved using a monopolar needle electrode for recording in extensor digitorum brevis (EDB) and flexor digitorum brevis (FDB) muscles, which encoded acceptable shape of CMAPs on tibial nerve stimulation. To avoid erroneous interpretation of electromyographic and nerve conduction studies, one should be aware of this possible innervation anomaly ("all tibial foot").

PURPOSE: Adhesion after flexor tendon injury is a result of fibrosis between tendon and tendon sheath. This, finally interfere with gliding mechanism of tendon and results in functional problem of hands. Therefore, there have been many trials to reduce adhesion around the tendon. However, there is no standard procedure clinically practiced in hospitals. Mitomycin-C is an antineoplastic alkylating agent that decrease fibroblast proliferation and scar formation. It is commonly used in many surgery to reduce postoperative adhesion. This study was designed to observe the effect of Mitomycin-C on preventing adhesion in injured flexor tendon. METHODS: The deep flexor tendon of digit 2 and 4 in the left forepaw of 15 New Zealand White rabbits were subjected to partial tenotomy. In study group, injury site was exposed to a single 5-minute application of Mitomycin-C, and in control group was left untreated. Digit 2 and 4 in the right forepaw of each rabbit were considered as non-adhesion control group. After 2 weeks, the animals were sacrificed and digits were amputated for biomechanical test and histological study. RESULTS: In biomechanical study to measure yield point, mean yield point of non-adhesion control was 17.43+/-2.33 and 25.07+/-4.03 for adhesion control, which proves increase of adhesion in adhesion control group(p<0.05) in 95% confidence. In Mitomycin-C group, mean yield point was 12.71+/-4.97. Compared with adhesion control, there was decrease in adhesiveness in Mitomycin-C group(p<0.05) in 95% confidence. In histological study, the result of adhesion control revealed massive adhesions of bony structure, fibrotic tissue and tendon structure with ablation of the border. However in Mitomycin-C group, we could find increased fibrotic tissue, but adhesion is much lesser than adhesion group and borders between structures remain intact. CONCLUSION: This study suggests that Mitomycin-C can significantly reduce adhesion of injured flexor tendon in rabbit model.
