Cellular schwannoma is a very rare benign tumor involving peripheral nerves, mimicking malignant nerve sheath tumor in histological appearance. It is a clinico-pathological variant of benign schwannoma characterized by a high cellularity, increased mitotic figures and occasional presence of bone destruction. A 6-month-old female patient was admitted with progressive quadriparesis. Magnetic resonance imaging of the cervical spine showed a well-enhancing extramedullary mass on the C4 to C6 area. Total laminectomy was performed on C4-7, and intradural extramedullary tumor was removed. Histologically, the tumor was composed of proliferated spindle cells. Most of the tumor was composed of Antoni A area with hypercellular spindle cells arranged in fascicular pattern. The tumor cells showed mild atypism with mitotic figure upto 4/10HPF and diffuse, strong S-100 protein immunostaining. The patient was improved postoperatively.

Interferon (IFN) alpha is commonly used for the treatment of chronic hepatits C with a combination of ribavirin. There are numerous dermatologic adverse events of IFN, such as xerosis, pruritus, alopecia, and injection site reaction. Panniculitis is one of the rare cutaneous side effects of IFN treatment, which may have a significant reduction on patient's quality of life and may lead to discontinuation of the treatment. Although there have been several reports of panniculitis induced by IFN-beta, IFN-alpha induced panniculitis are rarely reported in the literature. Herein, we report a case of panniculitis caused by pegylated IFN alpha2a injection in a patient with chronic hepatitis C.

PURPOSE: The most important step for patients who come to the emergency department with ureter stones is acute pain management. There have been insufficient studies on what factors affect acute pain management for ureteral colic the most. In this study, patients with ureteral colic were divided into two groups: one group, in which the pain was first managed with an analgesic, and another group with unmanaged pain, to find factors that most affect additive analgesics administration for ureter stones. METHODS: There were 121 patients, eventually confirmed for the presence of ureter stones through a computed tomography CT scan, included in this study. When ureter stones were suspected after the initial patient evaluation, initial pain was assessed through numerical rating scale (NRS) and the first analgesic was administered once. Pain was reassessed through NRS after 30 minutes. At that time, if the pain was managed, the patient was assigned to Group 1. If the pain persisted, another analgesic was administered for the second and third time, and the patient was assigned to Group 2. Finally, ureter stones were identified through CT scan. RESULTS: There were 58 patients (47.9%) in Group 1 and 63 patients (52.1%) in Group 2. There were no statistically significant differences in average age, serum creatinine, size of ureter stone, and severity of hematuria between the two groups. The differences in NRS measured initially and after 30 minutes were statistically significant (7.6+/-1.4 vs. 8.6+/-1.2, p<0.001; 1.4+/-1.3 vs. 6.6+/-1.9, p<0.001, respectively). The presence of hydronephrosis and perirenal edema were also statistically significant (p<0.001, p=0.007). The affecting factor for the administration of additive analgesics was hydronephrosis (odds ratio 7.213, p<0.001). CONCLUSION: Hydronephrosis is an important factor in the treatment of patients with additive analgesics. It can also be used as a predictive index to assess the severity of pain in patients with ureter stones.

Addisons disease is relatively rare than secondary adrenal insufficiency and result from progressive adrenocortical destruction. The common causes are idiopathic autoimmune atrophy and tuberculosis of adrenal glands. It is generally regarded as incurable in the sense that substitution therapy is required for the rest of the patients life. We report a case of tuberculous primary adrenal insufficiency which was confirmed by biopsy. This case was treated with antituberculous medication and showen to have improved adrenocortical function after six months.

BACKGROUND: Myxoma makes up close to 50% of adult primary cardiac tumors, and this mainly occurs in the left atrium, and rarely in the right atrium or ventricle. The patients clinically present with symptoms of hemodynamic obstruction, embolization or constitutional changes. Diagnosis is currently established most appropriately with 2-D echocardiography. Surgical resection of myxoma is a safe and effective treatment. MATERIAL AND METHOD: We reviewed our clinical experience in the diagnosis and management of 57 cases of cardiac myxoma that were seen over a 20-year period from July 1984 to July 2004. RESULT: The mean age of the patients was 53.5+/-14.0 years (range: 12 to 76 years). There were 38 (67%) females and 19 (33%) males. The preoperative symptoms included dyspnea on exertion in 27 patients, palpitation in 4, chest pain in 9 and syncopal episode in 4. The diagnosis was made by echocardiography alone in 51, and by combination of echocardiography, CT and angiography in 6. The tumor attachment sites were the interatrial septum in 50, the mital valve annulus in 3 and the left atrial wall in cases. The tumor was excised successfully via biatriotomy in 33 (58%), left atriotomy in 15 (26%), the septal approach via right atriotomy in 3, Inverted T incision in 3 and the extended septal approach in 3. The follow-up time ranged from 1 to 229 months (mean follow-up: 84.0+/-71.3 months). There were no early and late deaths and no recurrence during the follow-up period except for follow-up loss in 5 patients. CONCLUSION: It's concluded that excision of cardiac myxoma is curative and the long-term survival is excellent. Immediate surgical treatment was indicated because of the high risk of embolization or of sudden cardiac death. Radical tumor excision may prevent recurrences.

OBJECTIVE: Etoposide is a potent and widely used antineoplastic agent. It is able to induce apoptosis in most cell types. However, very little is known about its mechanism of action. In this study, we demonstrate the cytotoxic signal that induced by etoposide and investigate how etoposide exerts antitumor activity in HPV-16 (+) CaSki cervical carcinoma cells. METHODS: Antiproliferation activity was measured in CaSki cell lines by using MTT assays, DNA fragmentation assay. Cell cycle distribution was analyzed using flow cytometry. Expression of proteins involved in the apoptotic pathway was analyzed by Western blotting (WB). Electron microscopic (EM) and biochemical studies (Western blotting, RT-PCR) revealed that non-apoptotic death was associated with autophagosomes/-autolysosomes. These parameters have also been measured in cells treated with 3-methyladenine (an autophagy inhibitor), zVAD-fmk (a pan-caspase inhibitor) and both. RESULTS: The etoposide induced apoptosis. In cell cycle analysis, etoposide-treated CaSki cells were few induced hypodiploid DNA content, suggesting that apoptotic cell death. EM study revealed that autophagic appearance in the presence of etoposide exhibited by autophagosomes/autolysosomes. It was confirmed by LysoTracker probe and WB against Beclin 1, APG 5, APG 12 and p53. When autophagy was blocked by 3-MA, not only the protein expression of Beclin 1, but also the antitumor effect of etoposide was suppressed. On the other hand, the addition of zVAD-fmk could induce a few etoposide-induced autophagy. And etoposide-treated CaSki cells were rescued by combination of 3-MA and zVAD-fmk. CONCLUSION: Our results suggest that etoposide not only initiated apoptosis but ultimately caused cell death through autophagy. In this study, we demonstrate novel features for the action of etoposide in HPV-16 (+) CaSki cervical carcinoma cells. Autophagic cell death induction by some anticancer agents underlines the potential utility of its induction as a new cancer treatment modality.

Multiple primary cancer is defined as the case of primary malignant tumors of different histologic origins each other in one person, The incidence of multiple primary cancer has been increasing recently due to more developed diagnostie procedure and long survival of cancer patients. In esophageal cancer patients, comibined prevalence of other malignancy is rela tively high. We have experienced three cases of gastric adenocarcinoma with esophageal squamous cell carcinoma and report these cases with a review of literatures.
