The potential for sebaceous nevi to evolve into secondary benign or malignant EuIror is well recognized. In general, malignant transformation does not occur until postpubertal life. We experienced a case of basal cell epithelioma arising in a nevus sebaceous on a 12-year-old boy´s parietal scalp. We recommended that surgical excision should be undertaken as early as possible to detect the malignant transformation of nevus sebaceous.

PURPOSE: It is critical that the exact gestational age of a newborn baby, especially premature baby, be determined to evaluate the status of a disease and its management and to estimate the prognosis of a patient. This study aimed to investigate an easy and accurate method to estimate gestational age on cranial ultrasound, requiring minimal additional time and equipment. METHODS: A high-resolution coronal sonographic image was obtained via the anterior fontanel with a 5-12 Mhz linear probe after the usual cranial sonographic examination. We measured the depth of cerebral hemisphere, thickness of corpus callosum, and depth of cingulate sulcus and obtained the correlations between these factors and gestational age. RESULTS: Depth of cingulate sulcus had the highest correlation coefficiency with gestational age (r=0.878, P=0.000). All the cases, except for 2 cases, had a gestational age of more than 37 weeks, when the depths of cingulate sulcus were more than 0.55 cm, and had a gestational age less than 34 weeks, when the depths of cingulate sulcus were less than 0.35 cm. CONCLUSION: Measurement of the depth of cingulate sulcus was a simple and accurate method to estimate the gestational age on cranial ultrasound. The gestational age is more than 37 weeks, when the depth of cingulate sulcus is more than 0.55 cm, and is less than 34 weeks, when the depth of cingulate sulcus is less than 0.35 cm.

Journal of the Korean Neurological Association 2009;27(2):158-162
BACKGROUND: High-density calcifications on CT images can appear as high signals on T1-weighted MR images, but with differing extents and degrees. This study investigated CT and MR images of calcifications of various types and concentrations. METHODS: We analyzed CT and MR images of two cases of bilateral basal ganglia calcifications and experimental suspensions of calcifications of different types and concentrations. RESULTS: The density of CT calcifications increased in proportion to their concentration regardless of their type. However, the MR signals differed with the types and concentrations of calcification. A high signal was one of the most noticeable signs on T1-weighted MR images for calcium phosphate, and it increased for concentrations up to 0.2 g/mL before leveling off. The signal for all types of calcification decreased on T2-weighted and especially fluid-attenuated inversion recovery (FLAIR) images. CONCLUSIONS: High signals are characteristic of calcification on T1-weighted MR images, and are often stronger than those on CT images. A low signal appears consistently on FLAIR MR images regardless of the calcification type. These findings might be helpful in evaluating calcifications apparent in MR images.

The skin over the nose is less mobile for primary closure of defects. In addition to skin graft and secondary intention healing, there are various local flap techniques and their modifications for the reconstruction of nasal defects. Imprecise engineering of wound repair methods and contracture can lead to twisting of the nose and distortion of surrounding anatomic structures such as the nasal ala and paranasal sulcus. The skin defects on the nasal dorsum were reconstructed with a modified bilateral rombic flap. In our case, there were no significant complications and the final result was satisfactory in both functional and cosmetic aspects. Through our experience, we can confirm that the modified bilateral rhombic flap can reconstruct defects on the center area of the nasal dorsum effectively and in a single stage.

Intestinal obstruction occurs rarely as a cause of acute abdominal pain during pregnancy. It is very difficult to make diagnosis, as nausea, vomiting and abdominal pain are commonly associated with pregnancy, and X-rays are avoided if possible. However, delayed diagnosis can cause intestinal strangulation, which results in a high incidence of maternal morbidity, mortality, premature labor, and fetal loss. The incidence of intestinal obstruction seems to increase at the time of rapid uterine size changes such as between 16~20 weeks, 32~36 weeks or even in the puerperium. The possibility of intestinal obstruction must always be kept in mind when a pregnant woman with an operation scar on her abdomen develops abdominal pain. We present a case of small bowel obstruction during early pregnancy with a brief review of the literature who had the history of right salpingo-oophorectomy and appendectomy operation

Erythema ab igne is a relatively uncommon skin lesion caused by chronic exposure to low levels of infrared heat from open fires or stoves, and is characterized by reticulated hyperpigmentation on the exposed skin. Recently, exposure to various 'new' heat sources, such as heated furniture, car heaters, or even laptop computers, has been reported to cause this condition. We present a case of 31-year-old Korean woman with reticulated hyperpigmentation on her feet, which had occurred due to bathing her feet in hot water on a daily basis.

To compare the regenerative effect of direct end-to-end suture, nerve graft and sutureless fibrin glue repair in the rat sciatic model, forty rats were divided into 4 groups: normal control group(NC-G, n=6), direct end-to-end suture group(DS-G, n=12), nerve graft group(NG-G, n=10) and sutureless fibrin glue group(FG-G, n=12). One half of each group except NC-G was sacrificed 4 weeks later and the other half was sacrificed 14 weeks later. The repair site was assessed by nerve conduction studies and quantitative morphometry. Regeneration index (RI) was defined as a total number of remyelinated axons in one quarter of 3X5 inch sized microphotograph. The comparison among groups was analyzed statistically by Kruskal-Wallis 1-way ANOVA and Mann-Whitney test. Nerve conduction study done 14 weeks later revealed that latency was 1.7ms+/-0.18(DS-G), 2.4ms+/-0.35(NG-G), 2.4ms+/-0.17(FG-G) and amplitude was 20.1mV+/-2.89(DS-G), 12.0mV+/-2.47(NG-G), 13.7mV+/-2.95(FG-G). RI was 281+/-37.5(DS-G), 227+/-14.4(NG-G) and 217+/-22.2(FG-G). There was a statistical difference in the latency, amplitude and RI between three groups(p<0.05), but there was no statistical difference in the latency, amplitude and RI between FG-G and NG-G(p>0.05). Regenerative effect of fibrin glue is not different from that of nerve graft, therefore fibrin glue repair can facilitate inaccessible nerve repairs in skull base or spinal surgery.

BACKGROUND: Skin tags are benign fleshy or darker colored papillomatous dermal tumors locatei mostly in the neck, axill or groin. Recent reports on a possible association between skin tags and colonic polyps, however, caused interest in these henign tumors of the dermis, especially wite regarding to their frequercy. OBJECTIVE: The purpose rate this study was to explore the clinical profiles of skin tags, the effect of obesity on the frequeny of skin tags and the association between skin tags and obesity in the normal population. We also tried to evaluate the usefulness of skin tags as a general marker for the presence of colonic piyps. METHODS: The first, 524 unselected patients were examined. The patient material comprised of 240 males and 284 females. Each patient was inspected with regard to skin tags by a clermatolgist. 334 patients were classified into obese groups and nonobese groups and then we evaluated the relationship between skin tags and the degree of obesity. The second, ninety consecutive patients referred for coloniscopic evaluation were examined to determine the association between skin tags and colonic polps. RESULTS: We found 22.9% of the males and 22.5% of the females to be skin tag carriers in the general population. We also noticed a steady increase of the frequency according to age eccept for the third decads. Of the skin tags found 51% were in the axillar region, 40% around the neck and 8% in the inguinal region. In the study for the relationship between skin tags and obesity, 44.9% of the obise patients and 23% of the nonobese patients were skin tag carriers(relative risk=1.95, p<0.05). In the study for the association between skin tags and colonic polyps in patients undergoing colonoscopic examination, 18 of patients with skin tags(45%) hnd colonic polyps and 11 of patients without skin tags(22%) had colonic polyps(relative risk=2.05, p<0.05). CONCLUSION: This study identified an obese group that are at risk of the developing skin tags. Consideration of skin tags as a marker for colonic polyps is likely to prove helpful.

PURPOSE: To evaluate the usefulness of endoanal ultrasonography and to determine the imaging features of patients with fecal incontinence, anal abscess or anal fistula. MATERIALS AND METHODS: Twenty five patients underwent endoanal ultrasonography between October 1995 and July 1996. Ten of these were fecal incontinence cases, eight had an anal abscess, and seven, an anal fistula. The incontinence grading scale (IGS) was used for clinical grading of fecal incontinence and pudendal nerve terminal motor latency (PNTML) for pudendal nerve injury. Endoanal ultrasonographic features and operative findings were retrospectively reviewed. RESULTS: Endoanal ultrasonography revealed defective sphincteric muscles in all three patients with myogenic fecal incontinence, but in six of seven cases with neurogenic fecal incontinence, these muscles were not defective. Myogenic and neurogenic incontience showed different findings (p=0.033). In comparison with surgical findings, endoanal ultrasonography was 88% accurate in anal abscess cases and 86% accurate in those of anal fistula. CONCLUSION: Endoanal ultrasonography in conjunction with PNTML was very useful for the detection of the site and severity of sphincteric muscle defect and diagnosis of the etiology of fecal incontinence. Through analysis of the site and type of lesion, the procedure can also serve as a guide to the surgical treatment of patients with anal abscess or fistula.
