We report a case of a 6-month-old female who had had verrucous hemangioma since birth. The lesions were dark red, verrucous surfaced, hyperkeratotic papules on the right sole. A histopathological examination showed hyperkeratosis, papillomatosis, irregular acanthosis, lobular proliferation and dilatation of blood vessels in the deep dermis with a gap devoid of vessel proliferation in the mid dermis.

Paederus dermatitis is a linear and self-healing blistering disease of the skin caused by contact with insects belonging to genus Paederus(Coieoptera : Staphylinidae). There have been only a few reports of paederus dermatitis in the southern part of Korea since 1968. We recently experienced a case of paederus dermatitis due to contact by P. fuscipes.

Pigmented fungiform papillae of the tongue is a rare disorder in Korea. It is characterized clinically by pigmentation confined to the fungiform papillae and histopathologically by the presence of melanophages in the upper dermis. We report a case of pigmented fungiform papillae of the tongue in a 21-year-old woman who had brown to violaceous dots on the fungiform papillae and pigmented patches on the right lateral dorsum of the tongue. Histological findings showed increased melanophages in the upper dermis.

This study was intended to investigate the pre-and postoperative profile of seizures in the patients with cerebral arteriovenous malformatins(AVM's), and to evaluate various preoperative factors to predict the postoperative occurrence of seizures. The patients consisted of 46 consecutive cases with supratentorial AVM's operated on from May 1987 to May 1993. Their mean follow-up duration was 40 months. The pre- and postoperative seizure profiles were similar to each other. The overall incidence of patients experiencing seizure were 50% preoperatively and 52% postoperatively, and the incidence of intractable seizure was 15%, which was the same in both the pre-and postoperatively period. The presence of preoperative seizure and large size of AVM were significant indicators of high incidence of postoperative seizures(P<0.05), while other factors such as preoperative intracerebral hemorrhage or embolization showed no significant influence on the occurrence of postoperative seizures. About 70% of the patients with preoperative seizures also had postoperative seizures, while those without preoperative seizures developed new ones only in 35% of the cases postoperatively. The mean size of the AVM's in the group, with postoperative seizures was larger than that of the group without postoperative seizures(4.56 vs. 3.02 cm). Regarding postoperative intractable seizures, 57% of the group with preoperative intractable seizures remained intractable postoperatively and groups with preoperatively controlled and groups without seizures demonstrated postoperative intractablity only in 13% and 4% respectively. In conclusion, surgery of AVM's did not change the overall incidence of seizures, both controlled and intractable, and patients with preoperative and large sized AVM's and significantly higher possibility of postoperative seizures. Patients with preoperative intractable seizures resulted in control of seizures in 43% after removal of AVM, while 57% remained intractable. Extirpation of epileptic focl, after localization with preoperative study, seems to be needed to improve the outcome of the postoperative seizures.

The hypersensitive reactions to ant stings vary from local to systemic. Because repeated stings may induce severe skin reactions or serious systemic allergic reactions, the concerns about minor skin reactions by ant stings have been increasing. A 34-year-old man was stung on the right forearm by an ant. He experienced erythematous papules with pain, burning and dyspnea. The stinging ants collected from the patients skin and the ants resident in his garden were identified as Brachyponera chinensis.

BACKGROUND: It has been known that the polymerase chain reaction(PCR) test of clinical specimens including blood, sputum, urine, and cerebrospinal fluid collected from patients with systemic fungal infection is a highly sensitive diagnostic method. Recently, the PCR test was applied to the diagnosis of onychomycosis. OBJECTIVE: This study was aimed to explore whether the PCR test would be a more sensitive diagnostic tool than the KOH smear, fungus culture and KONCPA(KOH+Nail Clipping+ PAS(periodic acid-Schiff) stain) test in diagnosing the onychomycosis. METHODS: Using 50 nail samples from 50 patients with onychomycosis, the result of the PCR test was compared with those of the KOH smear, fungus culture and KONCPA test. RESULTS: The results were as follows: 1. The positive rates for detecting the causative fungi from the KOH smear, fungus culture, KONCPA test and PCR test were 64.0%, 46.0%, 90.0%, and 100.0% respectively. 2. The fungus culture identified the causative fungi from 23 samples, of which 21(91.2%) were T. rubrum, 1(4.4%) Candida sp. and 1(4.4%) C. albicans. KONCPA test yielded higher positivity by detecting the pathogenic fungi in 45 samples: dermatophytes 35(77.8%), mixed infections of dermatophytes and Candida sp. 6(13.3%), molds 2(4.4%) and unclassified 2(4.4%). The PCR test yielded the highest positivity by detecting the pathogenic fungi in all samples ; T. rubrum 44(88.0%) and unclassified 6(12.0%). 3. Compared with the results of fungus culture and KONCPA test, that of PCR test showed some differences. The case of Candida sp. in fungus culture was identified as T. rubrum in PCR ; the case of C. albicans in fungus culture as unclassified in the PCR. Five cases of mixed infection and 2 cases of mold infection in the KONCPA test were diagnosed as T. rubrum infection in the PCR test. CONCLUSION: The PCR test is useful in diagnosing the onychomycosis because of its highest positive rate in detecting the causative fungi compared with fungus culture and the KONCPA test. Furthermore, a more accurate diagnostic method such as the PCR test will be necessary in case Candida sp. or mold is cultured from the infected nail specimen.

This study was designed to investigate the effect of diazepam on the spontaneous contraction and oxytocin induced contraction of the isolated rat uterus. Female rat (Sprague-Dawley) pretreated with oophorectomy and 4 days administration of estrogen. Weighing about 200 g, was sacrificed by cervical dislocation, and the uteruses were isolated. A longitudinal muscle strip was placed in temperature controlled (37℃) muscle chamber containing Locke's solution and myographied isometrically. Diazepam inhibited the spontaneous contraction and oxytocin induced contraction of the isolated rat uterus in a concentration-dependent manner. GABA, muscimol, a GABA A receptor agonist, bicuculline, a competitive GABA A receptor antagonist, picrotoxin, a non competitive GABA A receptor antagonist, baclofen, a GABA B receptor agonist, and delta-aminovaleric acid, a GABA B receptor antagonist, did not affect on the spontaneous and oxytocin induced contraction of the isolated rat uterus. The inhibitory actions of diazepam on the spontaneous and oxytocin induced contraction were not affected by all the GABA receptor agonists and antagonists, but exceptionally potentiated by bicuculline. This potentiation-effect by bicuculline was not antagonized by muscumol. In normal calcium PSS, addition of calcium restored the spontaneous contraction preinhibited by diazepam and recovered the contractile of oxtrocin preinhibited by diazepam. A23187, a calcium inophore, enhanced the restoration of both the spontaneous and oxytocin induced contraction by addition of calcium. In calcium-free PSS, diazepam suppressed the restoration of spontaneous motility by addition of calcium but allowed the recovery of spontaneous motility to a considerable extent. Diazepam could not inhibit some development of contractility by oxytocin in calcium-free PSS, but inhibited the increase in contractility by subsequent addition of calcium. These results suggest that the inhibitory action of diazepam on the rat uterine motility does not depend on or related to GABA receptors and that diazepam inhibits the extracellular calcium influx to suppress the spontaneous and oxytocin induced contractilities.

Erythropoietic protoporphyria (EPP) is an autosomal dominant condition due to decreased activity of ferrochelatase. The disease is characterized by a wide range of photocutaneous changes and occasionally by liver disease. The level of protoporphyin is raised in erythkocytes and it may also be increased in the feces. We report herein a case of EPP present in a family which was diagnosed by a high free erythrocyte protoporphyrin (FEP) count.
