Aneurysm of the splenic artery are the third most common intra-abdominal aneurysm, following aneurysms of the infrarenal aorta and iliac arteries. Splenic artery aneurysms (SAA) are the most frequent visceral artery aneurysms and account for more than two thirds of all lesions. Incidence of SAA are rare clinical entities(0.01-0.2%) that carry risk of rupture and fatal hemorrhage(35-100%). Fibroblastic dysplasia and atherosclerosis is fecund in the majority, and the fact that these aneurysms developes more commonly in female. Most patients are asymptomatic and the diagnosis is generally made incidentally. The treatment of patient with known SAA is dictated by several factors, including location, age, sex, present of symptom, size, pregnancy. We report ruptured splenic artery aneurysm with hemoperitoneum and review of the literature.

BACKGROUND: Dizziness is a common complaint in patients presenting at emergency departments. Dizziness is difficult to assess because it is a subjective complaint that cannot be measured. We report a clinical analysis of patients with acute dizziness: type, duration, symptom, incidence, etc. METHODS: We reviewed the clinical details and the results of vestibular function tests for 106 acutely dizzy patients who visited the Emergency Department of Wonkwang University Hospital during the period of Jul. 1999 through Dec. 1999. RESULTS: The most common etiology of acute dizziness was the peripheral vestibular system(66%). The most common disease of the peripheral vestibular system was benign paroxysmal positional vertigo(52.9%), and the second most one was vestibular neuronitis(42.9%). In the central nervous system, cerebrovascular accident(63.6%) was the most common cause. All of the patients had experienced a previous vertigo attack, and 42.4% of them had frequent attacks. Dizziness of the cochlear systems were usual in peripheral vertigo. The usual underlying diseases related with vertigo were hypertension, cerebral infarction and diabetes mellitus. CONCLUSION: Dizziness is a complex and frustrating symptom with numerous possible causes. In case with suspected central disorders, CT and MRI have a great diagnostic significance.

BACKGROUND: Essential tremor is one of the most common types of movement disorders. Although it is sometimes prefaced with the term 'benign', it often causes significant disabilities. Clinical characteristics and responses to various drugs have not been investigated systematically in Korea. Therefore, we studied the clinical features, electrophysiologic findings, and drug responsiveness of essential tremor. METHODS: Forty-five patients were included in the study by clinical criteria for essential tremor. We investigated their clinical features including tremor type, involved sites, family history, and responsiveness to alcohol. We used an electromyography study to evaluate the contraction patterns between agonist and antagonist muscles and the frequency of tremor. Primidone and propranolol were prescribed to all the patients (N=30) with a sufficient washout period (more than 2weeks) for drug responsiveness. Drug responsiveness was estimat-ed with self-assessment scales. RESULTS: The mean age of patients at the onset of the tremor was 45 years and the average duration of the tremor was 11.1 years. Kinetic tremor was dominant in 17 patients (37.8%) and postural tremor in 28 patients (62.2%). Family history was found in 18 patients (40%) and alcohol reduced tremors in 18 (64.8%) out of 28 patients with sufficient alcohol intake. Co-contraction was seen in 18 patients (40%), alternative contraction in 15 (33.6%), and mixed contraction in 3 (6.7%). Mean frequency was 6.7 Hz. Propranolol reduced tremor in 24 patients (80%), and primidone in 27 patients (90%). CONCLUSIONS: It was concluded that essential tremor was heterogenous clinically and electrophysiologically. Primidone was found more effective than propranolol in reducing tremor.
