Hyperhidrosis is common complication of spinal cord injury, but localized unilateral hyperhidrosis is relatively rare disorder without autonomic disreflexia. A 52-year-old man with a 10-month history of cervical injury induced tetraplegia complained of excessive intermittent left-sided sweating. The sweating occurred by urinary retention or without any autonomic dysreflexia. The patient sweated excessively on the left face and upper body. In the point of Differentiation of Syndrom (辨證), the patient was diagnosed as Gi-Heo-Hyeol-Eo (Pi-Wei-Qi-Xu 氣虛血瘀) and was administered revised Boyanghwano-tang (reserved Bu-Yang-Huan-Wu-tang), and he was almost complaint free during 4 month about none dysreflexial hyperhidrosis.

A 10-year-old, female spayed mixed-breed dog with a history of vomiting and anorexia was examined. Abnormal findings of comlete blood count and serum chemistry included polycythemia, thrombocytopenia, hyper-globulinemia and hypoalbuminemia. Abdominal radiographs revealed severe unilateral renomegaly, and ultrasonography showed a left-sided renal mass. During the operation, left kidney was resected. Cytologial and histopathological examinations revealed neoplastic lymphoid proliferation with high mitotic figures in renal mass. Immunohistochemistry revealed tumor cells were CD3-positive and CD79${\alpha}$-negative, consistent with T-cell lineage. The renal mass of this case was diagnosed as renal T cell lymphosarcoma.

Let M be a fixed left R-module. For a left R-module X, we introduce the notion of M-prime (resp. M-semiprime) submodule of X such that in the case M=R, it coincides with prime (resp. semiprime) submodule of X. Other concepts encountered in the general theory are M-$m$-system sets, M-$n$-system sets, M-prime radical and M-Baer's lower nilradical of modules. Relationships between these concepts and basic properties are established. In particular, we identify certain submodules of M, called "primeM-ideals", that play a role analogous to that of prime (two-sided) ideals in the ring R. Using this definition, we show that if M satisfies condition H (defined later) and $Hom_R(M,X){\neq}0$ for all modules X in the category ${\sigma}[M]$, then there is a one-to-one correspondence between isomorphism classes of indecomposable M-injective modules in ${\sigma}[M]$ and prime M-ideals of M. Also, we investigate the prime M-ideals, M-prime submodules and M-prime radical of Artinian modules.

We are reporting an unusual case of dural arteriovenous fistula (AVF) of the superior sagittal sinus (SSS) after tamoxifen treatment for breast cancer. A 30-year-old female arrived at the emergency room with a sudden headache and left sided weakness and sensory loss. In her past medical history, she was diagnosed with breast cancer 1 year prior, and subsequently underwent a breast conserving mastectomy with whole breast radiation and adjuvant chemotherapy with tamoxifen. At the time of admission, computed tomography showed a small acute intracerebral hemorrhage at the right parietal cortex, and magnetic resonance imaging showed that a dural AVF at the SSS with a prominent and tortuous venous enhancement along the centrum semiovale was present. Cerebral angiography showed that the dural AVF at the mid-portion of the SSS with meningeal arterial feeding vessels entering the wall of the SSS, then draining through the dilated cortical veins. Our patient had no signs of active malignancy or any abnormalities in her coagulation profile, so it can be concluded that the tamoxifen was the likely cause of the SSS thrombosis and dural AVF. The dural AVF was treated by an endovascular coil embolization for the arterialized segment of the SSS. The patient dramatically recovered favorably from left side motor and sensory deficit. The best clinical approach is to screen potential patients of tamoxifen hormonal therapy and educate them on the sign and symptoms of life threatening thromboembolic events while taking tamoxifen.

Stenting is a useful alternative treatment modality in carotid artery stenosis patients who are too high-risk to undergo carotid endarterectomy (CEA). We report a case of contralateral cerebral infarction after stenting for extracranial carotid stenosis. A 78-year-old woman was admitted to the hospital with left-sided weakness. Based on magnetic resonance imaging (MRI) of the brain and conventional angiography, she was diagnosed with an acute watershed infarct of the right hemisphere secondary to severe carotid stenosis. Stenting was performed for treatment of the right carotid artery stenosis after a one-week cerebral angiogram was completed. Thirty minutes after stent placement, the patient exhibited a generalized seizure. Four hours later, brain MRI revealed left hemispheric cerebral infarction. Complex aorta-like arch elongation, tortuosity, calcification, and acute angulation at the origin of the supra-aortic arteries may increase the risk of procedural complications. In our case, we suggest that difficult carotid artery catheterization, with aggressive maneuvering during stenting, likely injured the tortuous, atherosclerotic aortic arch, and led to infarction of the contralateral cerebral hemisphere by thromboemboli formed on the wall of the atherosclerotic aorta.

Thoracic sympathetic ganglion block(TSGB) with alcohol is a traditional method for treating a variety of disease at pain clinics. But it is a difficult block to perform requiring both skill and experience. Therefore, we performed a thoracic endoscopic cauterization to evaluate the efficacy of this method. A patient suffering sever forearm and hand pain due to radius fracture of the right arm, one and half years earlier, was referred to several different orthopaedic department of various hospitals with continued aggravated symptoms. He was then admitted to our hospital's orthopaedic department. Our diagnosis, confirmed by thermography, revealed reflex sympathetic dystrophy. Patients was therefore referred to the pain clinic where treatment consisted of endoscopic thoracic sympathetic cauterization under general anesthesia. Patient was intubated with Robertashow 37 Fr. double lumen tube left sided. Left lateral and slight head up position was applied to make lesion side up. Incisions were made to penetrate trocas 5 mm diamether on 4 th intercostal space along mid axillary line and midclavicular line. Negative pressure suction on ipsilateral lung and CO2 insufflation under 10 mmHg was applied to reduce lung size. Cauterization on thoracic sympathetic chain at T3 level was done under endoscoic guide. 24 Fr. chest tube was inserted. Patient's symptoms cleared and he was satisfied with the results of this treatment.

The primary cardiac tumor was considered as a form of disease with poor prognosis in the past and it was hardly diagnosed before post mortem autopsy. But recent development of diagnostic procedure and the cardiac surgery using extracorporeal circulation increased the accuracy of diagnosis and the opportunity of successful treatment. The authors present two cases of left atrial myxoma which experienced during recent 4 years between 1979 and 1982. A 33 year old woman admitted with severe shortness of breath, generalized edema, ascites and the evidence of hepatopathy resulted from right sided heart failure. Preoperatively, the patient was treated with conservative medication to improve general condition for a few days. The tumor mass was removed successfully under the cardiopulmonary bypass. She, however, died of myocardial dysfunction showing low blood pressure. The tumor mass weighed 22gm and measured 5.2x4.5x3.6 cm in size. A 60 year old man admitted with shortness of breath on exertion and an episode of fainting. Following the removal of tumor mass under the cardiovascular bypass, the clinical course was satisfactory with no complication. The tumor mass weighed 105gm and measured 9x4x5 cm in size.

Spontaneous hemopneumothorax is a rare disease, and it can cause life threatening condition. It is characterized by the accumulation of more than 400 mL of blood and air in the pleural cavity without any other apparent causes. A previously healthy 22-year-old female patient presented with acute chest pain and dyspnea. Chest X-ray and computed tomography revealed a massive hemopneumothorax in the left hemithorax. The images showed a completely collapsed left lung with right-sided tracheal deviation, several pleural adhesion bands, and fluid collection with air-fluid level. We emergently performed a closed thoracostomy, and then 560 mL of fresh bloods were initially drained. We considered an emergent video-assisted thoracoscopic surgery for pulmonary wedge resection and bleeding control because of the massive hemothorax. However, the patient's vital signs were stabilized after blood transfusion and supportive cares for re-expansion pulmonary edema. The patient discharged from the hospital on 11^th in-hospital day after removal of the chest tube, and there had not been any recurrence of the pneumothorax for 10 months. We suggest that treatment strategy should be decided upon individually based on the patient's condition and clinical course of the disease.

Epithelial-myoepithelial carcinoma (EMC) of the salivary gland is a rare tumor that comprises approximately 1% of all salivary gland tumors. It has a distinctive histological appearance comprising ductal structures with an inner epithelial cell component and an outer layer of myoepithelial cells. We report a case of EMC of the parotid gland in a 41- year-old man. He presented left-sided subauricular swelling developed 3-month earlier. Neck CT scans revealed a well-defined mass in the left superficial parotid gland. He underwent superficial parotidectomy and was diagnosed as EMC. He was taken postoperative radiotherapy. There was no evidence of recurrence during a follow-up period of 12 months. A EMC is a low grade malignant tumor which can cause diagnostic confusion during workup and also frequently misdiagnosed as other benign or malignant tumor.

Choroid plexus papillomas (CPPs) are relatively rare neuroectodermal tumors that develop from choroid plexus epithelial cells and are usually restricted to the ventricles. Extraventricular CPPs are very unusual and can be difficult to diagnose and treat. A 50-year-old male patient was admitted to our clinic complaining of headache and visual deterioration. Neurological examination found no abnormalities except decreased light perception and secondary optic atrophy in the left eye. Endocrine testing revealed normal levels of hormones produced by the pituitary and target glands. Magnetic resonance imaging of the brain revealed a huge regular-shaped lesion in the sellar-suprasellar region occupying the sella turcica and extending into the suprasellar cistern and planum sphenoidale. The lesion was completely excised by microsurgery via an ordinary left-sided pterional approach. Histopathology identified the lesion as a choroid plexus papilloma. Following the case report, literature on the origin, differential diagnosis, and treatment of this rare tumor is reviewed.
