PURPOSE: To determine whether triple-phase multi-detector-row helical CT images of the liver improves the detection rate of hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Forty-one patients with 103 HCCs underwent triple-phase multi-detector-row helical CT imaging of the entire liver after contrast administration. Early and late arterial phase images were obtained serially during a single breath-hold, and portal venous-phase images were then obtained. Each image set was independently assessed for the presence of HCC by two radiologists unaware of the possible presence of tumors, and for each phase the detection rate was determined. For each arterial-phase image, lesion conspicuity (attenuation of a tumor compared with that of its parenchyma) was calculated. RESULTS: For reader 1, the detection rates for the early arterial, late arterial, and portal venous phase were 81%, 77%, and 55%, respectively, and for reader 2 were 83%, 81%, and 68%, respectively (p>0.05). When triplephase imaging findings were combined, the detection rate was significantly higher than when only those of the early or late arterial, and portal venous, phase were used (p<0.05). Mean lesion conspicuity for the late arterial phase was higher than for the early arterial phase, but the difference was statistically insignificant (p>0.05). CONCLUSION: Triple-phase imaging of the liver, involving the early arterial, late arterial, and portal venous phase, and using multi-detector-row helical CT, increases the detection rate of HCC.

BACKGROUND: Intermediate myasthenia syndrome(IMS) is thought to have clinical importance because it may cause sudden respiratory failure during the recovery phase of a cholinergic crisis of organophosphate poisoning. We designed this study to identify the prevalence, the inducing agent, clinical predictor, and the proposed treatment of IMS. METHODS: Patients who had admitted with the diagnosis of acute organophosphate poisoning from 1992 to 1998 at two teaching hospitals were enrolled in this study. We selected the cases of IMS based on a review of medical records using modified He's criteria. RESULTS: Twelve(12) out of 110 patients with acute organophosphate poisoning were diagnosed for a prevalence at 10.9%. The drug inducing IMS were identified as dichlorvos, fenthion, EPN, methidathion, and phosphamidon. The occurrence of IMS was not related to either the initial treatment with atropine and pralidoxime, or the level of serum cholinesterase. Complications were pneumonia, sepsis, pancreatitis, and pseudomembranous colitis, etc. Eleven(11) patients were discharged without sequelae, and one patient was discharged as a hopeless care. CONCLUSION: This study suggests that IMS is not rare, so close observation is required to detect IMS in organophosphate-poisoning patients. Also, more studies are required to find predictors and treatments.

Venous hemangioma is a vascular tumor that has been reported by such diverse names as; "cirsoid aneurysm", "arteriovenous hemangioma", "acral arteriovenous tumor" according to the author's opinions of its origin and histopathologic classification. It is benign and rarely biopsied, and it is also rarely reported in dermatology literature. We present two cases of venous hemangioma. The first case was a 64-year-old man who was presented with an elliptical dark-red plaque with overlying several grouped papules on the left periorbital area which had been present for 7 years. The second case was a 56-year-old man who was presented with a single red papule on the right postauricular area which had been present for 4 months. Histopathologically, there were a well-circumscribed proliferation of thick-walled muscle-containing blood vessels in the dermis. Intermingled with the thick-walled blood vessels, there were also thin-walled dilated blood vessels. In both cases, the thick-walled blood vessels resembled arteries, but they lacked elastic fibers on the Verhoeff van Gieson stain.

PURPOSE: The purpose of the study is to investigate the correlation between the symptoms and the incidence of anatomical variant without mucosal abnormality. MATERIALS AND METHODS: Out of 892 patients with CT performed for the evaluation of sinus disease symptoms between March 1991 and March 1993, we observed the anatomic variations in 82 symptomatic patients without mucosal abnormality(male:female=43:39, mean age 36. 4 years). The control group included 88 patients with facial bone CT performed for the evaluation of trauma during the same period while patients with recent paranasal sinusitis were excluded. (male:female=76:12, mean age 22. 4 years). The scouis were performed with 5-ram section thickness from posterior margin of sphenoid sinus to anterior margin of posterior ethmoid and then with 3 mm thickness from anterior margin of posterior ethmoid to anterior margin of frontal sinus. The artatomic variations included nasoseptal deviation, concha bullosa, Hailer cells, Agger nasi cells, etc. RESULTS: The anatomic variations were demonstrated in 71 our of 82 symptomatic patients(86. 5%), whereas they were seen 26 of 88 patients(29. 5%) in control group. CONCLUSION: Our data suggest that there is a possible causal relationship between anatomic variations and symptomas. Even though without accompaning mucosal abnormalities, anatomic variations could contribute simply to its symptomas. ^natomic variants may obstruct or narrow the airway, leading to turbulating air flow or interrupting ucociliary movement, and finally may produce a series os symptoms.

BACKGROUND: Although one hair usually arises from a single follicular opening in normal healthy subjects, we can see two or more hairs emerging from the single opening through close inspection. The latter is called "compound hair", described by Lowenthal in 1946, however, few reports on this have been made since. Histopatholoigcally two or more hairs which have an independant external root sheath arise from one follicular opening like its clinical appearance. We examined the distribution and density of compound hair in order to define its difference according to anatomical sites and aging process. OBJECTIVE AND METHOD: We counted the number of hairs in the circle(2 cm in diameter) at te frontal, temporal and occipital scalp of 24 old young men(22.5+/-2.0 years old) and 24 old men(64.4+/-12.9 years old), respectively. RESULTS: The summated number of grouped hair, which was mostly regarded at compound hair, was greater in the young group than in old group in the frontal area, but was smaller in young group than in old group in from the temporal and occipital areas. The proportion of grouped hair to total hair in the older group was lower in the frontal area, but higher in the temporal and occipital areas(p<0.05, p<0.01) according to aging process, however, no significant change was seen between the frontal area and the sum of single hair to compound hair was significantly decreased in the temporal and occipital areas(p<0.05, p<0.01) according to aging process, however, no significant change was seen between the frontal area and the sum of the three tested areas. CONCLUSION: Compound hairs are observed frequently on the scalp of normal healthy subjects and are most frequently seen on the occipital scalp in both of the young and old.

PURPOSE: We investigated whether myocardial SPECT had additional usefulness to clinical, functional or surgical indices for the preoperative evaluation of cardiac risks in noncardiac surgery. MATERIALS AND METHODS: 118 patients (M: F=66:52, 62.7+/-10.5 years) were studied retrospectively. Eighteen underwent vascular surgeries and 100 nonvascular surgeries. Rest T1-201/stress Tc-99m-MIBI SPECT was performed before operation and cardiac events (hard event: cardiac death and myocardial infarction; soft event: ischemic ECG change, congestive heart failure and unstable angina) were surveyed through perioperative periods (14.6+/-5.6 days). Clinical risk indices, functional capacity, surgery procedures and SPECT findings were tested for their predictive values of perioperative cardiac events. RESULTS: Peri-operative cardiac events occurred in 25 patients (3 hard events and 22 soft events). Clinical risk indices, surgical procedure risks and SPECT findings but functional capacity were predictive of cardiac events. Reversible perfusion decrease was a better predictor than persistent decrease. Multivariate analysis sorted` out surgical procedure risk (p=0.0018) and SPECT findings (p=0.0001) as significant risk factors. SPECT could re-stratify perioperative cardiac risks in patients ranked with surgical procedures. CONCLUSION:: We conclude that myocardial SPECT provides additional predictive value to surgical type risks as well as clinical indexes or functional capacity for the prediction of preoperative cardiac events in noncardiac surgery.
