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.

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.

Hemolytic disease of newborn due to Rhesus incompatibility occurs mostly by anti-Rh(D) antibodies. But recently, because of Rh(D) immune globuin prophylaxis, Rh(D) incompatibility is decreased and importance of minor group incompatibility is increasing. The majority of minor blood group incompatibilities are anti-c, anti-E or anti-Kell, but hemolytic diseases caused by combination of these antibodies are relatively rare. The 21 day-old male neonate was admitted because of pallor and poor feeding for 2 days. Laboratory data showed severe normochromic and normocytic anemia with increased reticulocyte and bilirubin. Patient's and his mothers blood type was B, Rh(D) positive. Minor blood groups of mother's and sons were different and anti-c and anti-E antibody were detected in mother's serum. After transfusions of two times with anti-c and anti-E free B, Rh(D) positive blood, the baby was discharged at 11th hospital day with good general condition.

Mobile computing environment is leading dynamic changes in our life. While the computer has been developed for complex calculation, it came to our life very closely with the help of wireless communication technologies and with the portability of the terminals. In the mobile computing environment, we can easily get the information from the wireless communication system while in the moving. Based on the wireless network technologies, we make use of applicable services for each mobile user. In this paper, we introduce several technologies supporting the mobile computing environment, and present the services, which are based on those technologies.

OBJECTIVE: The involvement of IGF system in hyperandrogenism and abnormal follicular development is controversial. This study is to assess whether IGF system contribute to it in the women with polycystic ovary(PCO). METHODS: Baseline serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol (E2), testosterone (T), androstenedione (ADD), prolactin, thyroid stimulating hormone (TSH), free insulin-like growth factor(IGF)-I, free IGF-II, insulin-like growth factor binding protein(IGFBP)-1, and IGFBP-3 were measured in twelve healthy regularly cycling volunteers and forty-two women with PCO then, the changes of baseline serum levels were evaluated after laparoscopic ovarian electrocauterization in nine PCO patients. In addition, the expression pattern of IGF-I and IGF-II was examined in the ovary of control and PCO group. RESULTS: Baseline levels of LH, ADD, free IGF-II, and IGFBP-3 were significantly higher in PCO group. However, there were no significant differences in the levels of free IGF-I and IGFBP-1, although free IGF-I showed decreasing tendency in PCO group. And there was a significant positive correlation between the LH and free IGF-II level in the PCO(P=0.011, r2=0.3899), but not in the control. After ovarian electrocauterization, LH, T, and ADD levels decreased, and free IGF-I and IGFBP-3 level increased. While free IGF-II and IGFBP-1 level showed no significant changes. In the ovary, expression of both IGFs showed similar pattern in normal and PCO ovaries. CONCLUSIONS: The elevated IGFBP-3 level may alter the bioavailability of IGF(s) in the PCO. The change in IGF-I level and resumption of ovulation after electrocauterization, suggest a possible role of IGF system in the impairment of follicular development in the PCO.
