BACKGROUNDs: A retrospective study was performed to define objective radiologic parameters in diagnosing epiglottitis on soft-tissue lateral neck radiographic study. METHODS: Parameters of soft-tissue structures(epiglottis width, third vertebral body width, ratio of epiglottic width to third vertebral body width) in 30 adult patients compared with those of age and sex-matched controls with foreign body in throat whose radiographic reading was normal. RESULTS: Epiglottis width of more than 11mm, ratio of epiglottis width(EW) to the third vertebral body width(C3W) of more than 0.5 were, respectively, found to be 100% sensitive and specific in differentiating between patients with and without epiglottitis. CONCLUSION: These preliminary results suggest that EW/C3W ratio of more than 0.5, EW of more than 11mm, respectively, may be useful in the diagnosis of epiglottitis in adult patients.

Congenital tuberculosis is an infection that is established in the fetus by hematogenous spread or by the aspiration or inhalation of infected amniotic fluid either before or during labor. The diagnosis can be confirmed only if both the tuberculous nature of the lesion and the antenatal origin of the infection can be proved. The authors analysed roentgen findings of two cases of pulmonary tuberculosis, thought to be congenital; 1. Diffuse distribution of nodular densities and some confluent densities were seen in the entire lungs in the inital film.The pulmonary markings were decreased in some degree. 2. Air bronchogram was noted. 3. Hepatosplenomegaly was associated.

Although percutaneous abscess drainage has become and accepted alternative from of therapy for selected patients with abscess, it is well known that there are several factors in the failure of adequate drainage such as pre-and post- procedural management, technique itself, various features of abscess, and selection and application of catheters. Among these factors, we made an experiment about drain efficacy of commonly used various catheters with different viscosities of water-glycerin solution under the two different pressure gradients. The experimental values of flow rate were lower than than the calculated values. An efficacy of experimental value was 4-14%. Because the inner diameter of fittings and stopcocks was usually smaller than the inner diameter of catheters, these factors also affected the drain efficacy. Finally, we though that it will be very helpful to the treatment of patients as well as to study about the catheter drainage, if the drain efficacy of individual catheters has been notified.

Optic nerve evulsion is a devastating, uncommon cause of sudden visual loss following major head trauma. Less frequently, it is associated with pointed non penetrating orbital injuries with minimal ocular trauma. Possible mechanisms of injury include extreme rotation and forward displacement of the globe, penetrating orbital injury causing a backward, pull on the optic nerve, and sudden increase in intraocular pressure causing rupture of the lamina cribrosa. Funduscopic examination may reveal total or partial lack of the optic disc and variable degrees of intraocular hemorrhage. Fluorescein angiographic finding is variable, visually evoked potential often shows the delay in latency or the decrese in amplitude, Computed tomography or magnetic resonance imaging usually demonstrates an intact optic nerve sheath. We report a case of optic nerve evulsion which diagnosed by retinoscopic finding, fluorescein angiography, computed tomography, and clinical history. We present it with a review of the literature.

Acute myocardial infarction after a bee sting is a very rare process. Among proposed mechanisms, vasospasm of the coronary artery is the most probable mechanism. Many mediators are included in the venom of wasps, and those mediators have vasoconstrictive properties and may constrict the coronary artery. Furthemore, those mediators have thrombogenic properties that lead to thrombogenesis in the coronary artery and aggravate myocardial ischemia. Epinephrine, commonly used in the management of anaphylactic shock, may further aggravate myocardial ischemia. We experienced two cases of acute myocardial infarction after a bee sting. In the first case, we could find no underlying abnormalities of the coronary vessel because the patient died during coronary angiography. In the second case, the electrocardiogram showed inferior wall myocardial infarction, but only mild stenosis of the right coronary artery was seen in coronary angiography.

Journal of the Korean Geriatrics Society 1999;3(1):56-63
BACKGROUND : Borame hospital nuns geriatric wards with 120 beds (40 beds for patients in Dept. of Internal Medicine, 40 for patients in Dept. of Orthopedics 40 for patients in Dept. of Neurology) from December 1996. We studied clinical characteristics of admissions to acute geriatric wards in Borame hospital in order to assess current status of geriatric wards in Korea. METHODS : 334 patients admitted from December 1996 to May 1997 were studied. By reviewing clinical records of these patients, we studied clinical characteristics of patients in geriatric wards retrospectively. RESULTS : 1) Age distribution: 8.6% of patients were over 85 years old. 16.4% of patients were between age of 80-84. 20.0% between 75-79, 31.3% between 70-74, 26.3% between 65-69, respectively. 2) Disease: 43% of patients have single disease, 67% of patients have multiple disease(23% of patients with 2 disease, 25% with 3 disease, 6% with 4 disease, 3% with over 5 disease respectively). 3) Mortality rate :Total mortality rates were 4.3% with 6.1% of patients in Internal medicine, 3.2% of patients in Neurology. These rates were much higher compared with mortality rates of 2.4% in general wards but similar to those (6.7%) in general wards in Internal medicine. 4) Causes of admission: Malignancies were most common causes of admissions in males, and then cerebrovascular diseases, infectious diseases, musculoskeletal diseases, in order. Musculoskeletal diseases were most common causes, and then diabetes mellitus, infectious diseases, cerebrovascular diseases. CONCLUSION : The elderly patients tend to have multiple diseases, longer hospital stays and higher mortality rates compared with younger patients in general wards. but differences of hospital stays and mortality rates are less than be expected.

The case of a patient with acute onset of flank pain is presented. Initial therapy was directed toward relief of pain believed to be caused by renal calculi. The flank pain did not responded to analgesics. An abdominal ultrasonogram showed that multiple hyperechogenic masses were in the parenchyma of both kidney, and an abdominal CT showed that multiple high-density masses, presumed to be angiomyolipomas, were located in both kidneys and in the perirenal hematoma around the left kidney. Vital signs were stable, and there was no evidence of anemia. On the seventh hospital day, angiographic tumor embolization was performed. Cases such as this should remind emergency physicians to carefully consider alternate diagnoses to renal calculi in patients with flank pain who have atypical clinical features or an atypical course.

BACKGROUND: Recent data suggest that the colonization rate of group B streptococci(GBS) in pregnant women and the incidence of neonatal infections by GBS is increasing trend in Korea, but the antimicrobial susceptibilities and serotypes in pregnant women have not been reported in Korea. So, we studied to define the antimicrobial susceptibility patterns and frequency of serotypes of GBS in pregnant women. METHODS: The susceptibility and serotyping of 60 GBS isolates from 27 pregnant women and four isolates from their two neonates were tested by an agar dilution method and agglutination test, respectively. The typing sera used in this study were Ia, Ib, II, III, IV, and V. RESULTS: Minimal inhibitory concentration range of 60 GBS from pregnant women were penicillin G 0.015-0.12 microgram/ml, vancomycin 0.5-2 microgram/ml, clindamycin 0.015-4.0 microgram/ml, chloramphenicol 2-4 microgram/ml, erythromycin 0.015-2 microgram/ml, tetracycline 0.5-256 microgram/ml, cephalothin 0.12-0.25 microgram/ml, ceftriaxone 0.03-0.12 microgram/ml, respectively. The resistance rate of GBS were 6.7% to clindamycin, 0% to erythromycin, and 98.3% to tetracycline. Most of GBS serotypes from pregnant women in decreasing order were Ib(48.3%), Ia(24.1%), III(20.7%). CONCLUSION: All GBS strains isolated from pregnant women are highly susceptible to commonly used antimicrobial agents with the exception of tetracycline. The low prevalence of severe neonatal GBS infections in Korea is not due to the absence of serotype III, but probably due to a low genital carriage rate of GBS by pregnant women.
