Objective : The Mini-Mental State Examination(MMSE) and Brief Cognitive Rating Scale(BCRS) are frequently using screening tests fur evaluating the cognitive function in clinical practice and research. The authors tried to evaluate the clinical usefulness of these tests for the patients with non-traumatic subcortical cerebrovascular disease. Method : We administered the MMSE and BCRS to 85 patients and 195 normal control group. In order to compare the test results according to the lesion site, we divided patients into left sided lesion group(21 patients), right sided lesion group(31 patients) and both sided lesion group(13 patients). Their cognitive function was evaluated by the BNA and daily living functional activity was examined by the IADLs(Instrumental Activities of Daily Living Scale)and GERRI(Geriatric Evaluation by Relative's Rating Instrument). Results : The results are as follows : 1) In the BNA, the patients scored significantly lower than control group at all items(except Right-Left Orientation and Motor Impersistence), but there were no difference in the MMSE(total score and all 5 items), and only 2 items(recent memory and self-care) were significantly different between two groups in the BCRS. 2) In the comparison by lateralization, there were significant differences among three groups at 3 items(Left Tactile Form Perception, Left Finger Localization and Right Finger Localization) in the BNA. But, there were no difference in the MMSE and BCRS. 3) In the correlation between daily living functioning and the MMSE/BCRS, control group showed no relation(except item of cognitive functioning), but patient group was significantly correlated with 3 items(social functioning, instrumental activities of daily living and cognitive functioning). Conclusions : These findings suggest that MMSE and BCRS are not useful as the test for cognitive function and discrimination of lateralization in patients with non-traumatic subcortical cerebrovascular disease. However, scores of these tests may be related with the functional level(such as daily living function) of patients.

Choroidal fissure cysts are often incidentally discovered. They are usually asymptomatic. The authors report a case of growing and hemorrhagic choroidal fissure cyst which was treated surgically. A 22-year-old female presented with headache. Cranial MRI showed a left-sided choroidal fissure cyst. Follow-up MRI showed that the size of the cyst had increased gradually. Twenty months later, the patient was admitted to our emergency department with severe headache. MRI and CT showed an intracystic hematoma. Although such cysts usually have a benign course without symptoms and progression, they may rarely present with intracystic hemorrhage, enlargement of the cyst and increasing symptomatology.

Central venous stenosis is a rare cause of unilateral breast edema occurring in hemodialysis patients that needs to be differentiated from other differential diagnoses, including, but not limited to, inflammatory breast carcinoma, mastitis, lymphedema, and congestive heart failure. All reports of similar cases in the available literature have described improvement or resolution of the edema after treatment. Herein, we report and discuss the pathophysiology of breast edema formation in a patient who presented with massive left-sided breast edema 7 years after being diagnosed with central venous stenosis. Medical and minimally invasive therapy had not been successful, so she underwent reduction mammoplasty to relieve the symptoms.

We focus our attention on a ring property that nilpotents are contained in the Jacobson radical. This property is satisfied by NI and left (right) quasi-duo rings. A ring is said to be NJ if it satisfies such property. We prove the following: (i) $K{\ddot{o}}the^{\prime}s$ conjecture holds if and only if the polynomial ring over an NI ring is NJ; (ii) If R is an NJ ring, then R is exchange if and only if it is clean; and (iii) A ring R is NJ if and only if so is every (one-sided) corner ring of R.

A 3-day-old Appaloosa colt was examined because of acute onset of ataxia, left-sided head tilt, fever and heart murmur. The foal continued to nurse but became increasingly depressed and mild colic. On plain radiological examination, the foal was normal. Uroperitoneum was diagnosed following abdominocentesis. Postmortem examination revealed bladder rupture. The lesion was in the dorsomedial part of the bladder wall. We suggested that the cause of bladder rupture was parturient trauma. Even though the rupture was associated with trauma, the margin of rupture of bladder was clearly smooth and regular.

The clinical, investigative, and surgical experiences were reviewed in four patients with congenitally corrected transposition of the great arteries who presented to the National Medical Center between August 1983 and August 1985. This condition is very rare congenital anomaly defined as the combination of atrioventricular discordance and transposition of the great arteries. Examples of primitive [single] ventricle inverted [that is, left sided in situs solitus] with outflow chamber were excluded in this paper. According to the sequential arrangement of the hearts there were two cases of [S,L,L] and two cases of [I,D,D]. The surgical approach should be focused on minimizing the risk of heart block and increasing the degree of relief of pulmonary outflow tract obstruction [POTO]. We experienced complete heart block in two cases of [S,L,L] and significant residual POTO in one case of [S,L,L] and one case of [I,D,D] postoperatively. There were one hospital mortality caused by complete heart block and residual POTO and two delayed mortalities caused by congestive heart failure and sepsis respectively.

Stellate ganglion block (SGB) is one of the most widely used treatment modalities for a broad range of disorders, including otolaryngologic indications such as Meniere's disease and sudden hearing loss. We present a case of a vertiginous attack following SGB for the management of Meniere's disease. A 31-year-old female, suffering from Meniere's disease, underwent repeated right side SGBs with 6 ml of 1% mepivacaine after negative aspiration tests for blood. The eleventh block was performed in the usual manner. Several seconds after injection, she showed agitation, anxiety, nystagmus, and left-sided tinnitus. Two minutes later, her tinnitus and nystagmus were resolved. Fifteen minutes after injection, she experienced acute onset of severe vertigo, nausea, and vomiting. However, her symptoms were gradually alleviated within two hours.

Unruptured non-traumatic dissecting aneurysm in the M4 segment of the middle cerebral artery (MCA) accompanied by complete occlusion of the ipsilateral internal cerebral artery (ICA) has never been reported. A 41-year-old man presented with an infarction manifesting as left-sided weakness and dysarthria. Magnetic resonance angiography revealed a subacute stage infarction in the right MCA territory and complete occlusion of the right ICA. Angiography demonstrated aneurysmal dilatation of the M4 segment of the right MCA. Surgery was performed to prevent hemorrhage from the aneurysm. The aneurysm was proximally clipped guided by Navigation-CT angiography and flow to the distal MCA was restored by superficial temporal artery-middle cerebral artery (STA-MCA) anastornosis. We report this rare case with literature review.

A 6-year-old female domestic short hair cat presented with acute onset of vomiting, anorexia, lethargy, and tachypnea. The cat was apparently healthy prior to presentation without history of trauma. On diagnostic imagings, the entire stomach and spleen were detected in the thoracic cavity. An emergent celiotomy was performed, and a type-4 hiatal hernia was confirmed; the stomach, spleen, pancreas, and duodenum were herniated through the esophageal hiatus. It was corrected using phrenicoplasty, esophagopexy, and left-sided gastropexy and there was no recurrence 16 months after surgery. This is the first case report of an idiopathic type-4 hiatal hernia in a cat.

Eagle syndrome is a rare condition caused by elongation of the styloid process or calcification of the stylohyoid ligament. Patients with Eagle syndrome typically present with dysphagia, dysphonia, cough, voice changes, otalgia, sore throat, facial pain, foreign body sensation, headache, vertigo, and neck pain. Here we report a case in which the patient initially presented with sore throat, left-sided facial pain, and cough. This case report provides a brief review of the diagnosis and nonsurgical management of this rare syndrome.
