We report two rare cases treated with coiling after rapid regrowth (within a month) of an aneurysm remnant on the middle cerebral artery (MCA) trunk after incomplete surgical clipping. The first case, a 47-year-old man with subarachonoid hemorrhage (SAH) (Hunt-Hess grade II, Fisher grade III) underwent clipping of a ruptured saccular aneurysm with a wide neck on the right early frontal branch arising from the MCA trunk. Incomplete clipping with a 1 mm sized remnant neck was performed to avoid sacrificing the lenticulostriate artery. In a follow-up cerebral angiogram on postoperative day 30, a rapid regrowth of the aneurysm remnant was observed, and on that day, complete obliteration was obtained by rescue endovascular treatment. The second case, a 48-year-old healthy woman with SAH (Hunt-Hess grade II, Fisher grade III) underwent clipping of an anteroposteriorly projecting bilobulated aneurysm on the left M1. Incomplete clipping with a minimal remnant neck was performed. In follow-up digital subtraction angiogram on postoperative day 30, a rapid regrowth of an aneurysm remnant involving only a part of the initial aneurysm near the neck was observed, and on that day, complete obliteration was obtained by rescue coiling. These patients were both discharged without any neurological deficits.

It has been known that activation of tyrosine kinases is involved in signal transduction. Role of the tyrosine kinase in vascular smooth muscle contraction was examined in deoxycorticosterone acetate (DOCA)-salt hypertensive rats. Male Sprague-Dawley rats underwent uninephrectomy, one week after which they were subcutaneously implanted with DOCA (200 mg/kg) and supplied with 1% NaCl and 0.2% KCl drinking water for 4-6 weeks. Control rats were treated the same except for that no DOCA was implanted. Helical strips of carotid arteries were mounted in organ baths for measurement of isometric force development. Genistein was used as a tyrosine kinase inhibitor. Concentration-response curves to 5-hydroxytryptamine (5-HT) shifted to the right by genistein in both DOCA-salt hypertensive and control rats. Although the sensitivity to genistein was similar between the two groups, the maximum force generation by 5-HT was less inhibited by genistein in arteries from DOCA-salt hypertensive rats than in those from controls. Genistein-induced relaxations were attenuated in arteries from DOCA-salt rats. Genistein affected the contraction to phorbol 12, 13-dibutyrate (PDBu) neither in DOCA-salt nor in control arteries. These observations suggest that tyrosine kinase is involved in 5-HT-induced vascular contraction, of which role is reduced in DOCA-salt hypertension.

OBJECTIVE: Although a high incidence of chronic subdural hematoma (CSDH) following traumatic subdural hygroma (SDG) has been reported, no study has evaluated risk factors for the development of CSDH. Therefore, we analyzed the risk factors contributing to formation of CSDH in patients with traumatic SDG. METHODS: We retrospectively reviewed patients admitted to Hallym University Hospital with traumatic head injury from January 2004 through December 2013. A total of 45 patients with these injuries in which traumatic SDG developed during the follow-up period were analyzed. All patients were divided into two groups based on the development of CSDH, and the associations between the development of CSDH and independent variables were investigated. RESULTS: Thirty-one patients suffered from bilateral SDG, whereas 14 had unilateral SDG. Follow-up computed tomography scans revealed regression of SDG in 25 of 45 patients (55.6%), but the remaining 20 patients (44.4%) suffered from transition to CSDH. Eight patients developed bilateral CSDH, and 12 patients developed unilateral CSDH. Hemorrhage-free survival rates were significantly lower in the male and bilateral SDG group (log-rank test; p=0.043 and p=0.013, respectively). Binary logistic regression analysis revealed male (OR, 7.68; 95% CI 1.18–49.78; p=0.033) and bilateral SDG (OR, 8.04; 95% CI 1.41–45.7; p=0.019) were significant risk factors for development of CSDH. CONCLUSION: The potential to evolve into CSDH should be considered in patients with traumatic SDG, particularly male patients with bilateral SDG.

PURPOSE: The objective of this study was to evaluate clinical results of dual miniplate fixation for comminuted or periarticular fractures of the hand. MATERIALS AND METHODS: Twenty cases in 18 patients who had comminuted or periarticular fractures of metacarpal or phalangeal bones were treated with dual miniplate fixation from April, 2007 to May, 2009. The mean followed up period was 14.7 months. Our study included comminuted or periarticular fractures which were difficult to keep the fixation by pining or single plating. We evaluated radiologic bony union, angular or rotational deformity, extensor tendon irritaion and total arc of motion. RESULTS: Bony union was achieved successfully after primary dual miniplate fixationin in 12 cases. In 7 cases with a nonunion following previous operative fixation, bony union was obtained by dual miniplate fixation and bone grafting. In one case who had received primary dual plate fixation, nonunion occurred due to massive bone defect. Bony union was obtained by secondary dual plate fixation and bone grafting. Postoperative rotational deformity, angular deformity and irritation symptom were not observed in all cases. Functionally acceptable range of active motion was restored by way of early active motion. CONCLUSION: The dual miniplate fixation is one of the useful method for comminuted metacarpal or phalangeal fractures which cannot obtain firm fixation by other methods.

Febrile ulceronecrotic pityriasis lichenoides et varioliformis acuta (PLEVA) is a very rare cutaneous disorder clinically characterized by the acute onset of erythematous papules, vesicles and large coalescent ulceronecrotic lesions on the whole body accompanied by high fever and severe constitutional symptoms. In general, ulceronecrotic lesion is preceded by a typical rash of PLEVA. Histopathologically, it shows widespread epidermal necrosis and fibrinoid necrosis of blood vessel walls in addition to the superficial and deep perivascular lymphocytic infiltrations. Several regimens including systemic corticosteroid, antibiotics, methotrexate or ultraviolet therapy have been challenged in this disorder . We report a typical case of febrile ulceronecrotic PLEVA in a 10-year-old child who showed a dramatic response to methotrexate.

PURPOSE: The purpose of this study was to evaluate clinical and radiological results after osteosynthesis of distal phalangeal nonunion with bone defect by using matchstick-shaped bone graft. MATERIALS AND METHODS: Fifteen distal phalangeal nonunions were treated with osteosynthesis using matchstick-shaped bone graft from September, 2009 to October, 2010. The mean age of patients was 36.1 years (range: 15 to 56 years). This study included 4 women and 10 men. The mean duration of follow-up was 16.8 months (range: 12 to 20 months). We evaluated radiographs, and measured postoperative visual analogue scale (VAS) score and pinch power. RESULTS: Union was achieved in all cases at a mean of postoperative 5.5 weeks (range: 4 to 6 weeks). The mean VAS score improved from 7.25 (range: 5 to 9) to 1.0 (range: 0 to 2) postoperatively. The mean postoperative pinch power was 7.75 lbs (range: 4 to 13 lbs) compared to opposite pinch power of 9.63 lbs (range: 5 to 15 lbs). There was no scar problem, pinch pain and other complication. CONCLUSION: Steosynthesis of distal phalageal nonunion with bone defect by using matchstick-shaped bone graft is technically feasible and simple in that it does not need volar incision and debridement. It is considered as an effective treatment option in distal phalangeal nonunion with bone defect.

PURPOSE: The presence of normal fingernail is important for the hand function and cosmetic appearance. We studied the results of the microsurgical reconstruction of the defected fingernail using composite toenail transfer. MATERIALS AND METHODS: From March of 2004 to May of 2009, eleven fingernails were reconstructed using microsurgical composite toenail transfer in 10 patients with a mean age of 27 years (range, 13 to 47 years). There were three thumbs, five index fingers, and three long fingers. Whole fingernail was destructed in three cases and remaining eight cases had partial nail defect. Toenail was grafted from great toe in eight cases and from second toe in three cases. Five cases were harvested as an osteoonychocutaneous flap, two as a endoosteoonychocutaneous flap and four as an onychocutaneous flap. RESULTS: All cases survived without any tissue necrosis. One arterial obstruction had occurred one day after surgery, which was resolved by repeated decompression and reanastomosis of the artery. All fingernails regenerated successfully. According to the rating system including assessment of shape, size and thickness of nail, nail pinch, pain, and patient's satisfaction, ten cases were rated as excellent and one as good. All patient's were satisfied with their hand function and appearance. CONCLUSION: Microsurgical composite toenail transfer can be an acceptable surgical reconstruction for the fingernail defect after trauma, providing satisfactory hand functions and cosmetic appearance.

Blue nevus may rarely appear in a plaque form. Because of its rarity and unusual appearance, this nevus may present a diagnostic problem and gives no definite prognosis. We report a case of plaque -type blue nevus in a 25-year-old man. He presented an irregularly demarcated plaque, measuring 1.5 x 3 cm, composed of multiple grouped slate gray to blue papules of varying size with intervening faint gray-blue discoloration on the back, which had existed for 10 years. Histopathological examination showed clumps of numerous heavily melanin-laden dendritic melanocytes in the reticular dermis with intervening stromal fibrosis. Numerous melanophages were intermingled with the melanocytes. There were no islands of pale cells seen in the cellular blue nevus and no malignant changes such as nuclear and cytoplasmic pleomorphism, mitotic figures and so on. The diagnosis of plaque-type blue nevus was made and its histopathological features were consistent with a common blue nevus.

OBJECTIVE: We evaluated the relationship between the expression of Ki-67 and thymidine-phosphorylase (TP) according to the cancerous progression of uterine cervical cancer with immunohistochemical method. METHODS: The material was obtained from hysterectomized uterus and punched cervical specimen for two years from 1998 to 1999 at the Soonchunhyang Chunan hospital. The material included 15 normal epithelium, 13 CIN I/II, 21 CIN III, 15 microinvasive carcinoma and 13 invasive carcinoma. Monoclonal antibodies of Ki-67 and TP were used for immunohistochemical determination of cellular proliferation and angiogenic activity. RESULTS: 1. The positive rate of thymidine phosphorylase in each group of normal epithelium, CIN I/II, CIN III, microinvasive carcinoma and invasive carcinoma were 6.7%, 23.1%, 38.0%, 73.3%, 84.6% respectively. 2. The labeling indexes of Ki-67 in each group of normal epithelium. CIN I/II, CIN III, microinvasive carcinoma and invasive carcinoma were 2.0+/-0.7, 26+/-5.4, 41.2+/-10.1, 74.7+/-9.3 respectively. 3. There was statistically significant relationship between TP and Ki-67 expression. CONCLUSION: The above results indicates that the angiogenic activities and cellular proliferation indices increase according to the invasiveness of cervical cancer. We were able to reveal the expression of TP and Ki-67 and their relationship in cervical carcinoma.
