Objective : The treatment of complex intracranial aneurysms remains challenging. One approach is the application of surgical flow alteration to treat aneurysms that are neither clippable, trappable, or coilable. The efficacy and limitations of surgical flow alteration have not yet been established. Methods : Cases of complex aneurysms treated with surgical flow alteration (proximal occlusion with or without bypass, distal occlusion with or without bypass and bypass only) were included in this retrospective study. Results : Among a total of 16 cases, there were 7 giant aneurysms (${\geq}25mm$ diameter) and 9 large aneurysms (>10 mm diameter); 15 of 16 aneurysms were unruptured. There were 8 aneurysms located in the anterior circulation, while the other 8 were in the posterior circulation. Aneurysms were treated with proximal occlusion in 10 cases and distal occlusion in 5 cases; in 1 case, the aneurysm occluded spontaneously after bypass without parent artery occlusion. All but 2 cases underwent prior or concurrent bypass surgery. Complete obliteration of the aneurysm at the latest imaging follow-up was shown in 12 of 16 cases (75.0%). Bypass patency was confirmed in 13 of 15 cases (86.7%). Surgery-related morbidity developed in 3 cases (18.8%, Glasgow outcome scale of 4) and all were perforator infarctions. There were no mortalities. Conclusion : Surgical flow alteration resulted in a high rate of aneurysmal obliteration with acceptable morbidity. Although several limitations remained, it could represent an alternative method for treating complex aneurysms.

Giant serpentine aneurysms are rare and have distinct angiographic findings. The rarity, large size, complex anatomy and hemodynamic characteristics of giant serpentine aneurysms make treatment difficult. We report a case of a giant serpentine aneurysm of the right middle cerebral artery (MCA) that presented as headache. Treatment involved a superficial temporal artery (STA)-MCA bypass followed by aneurysm resection. The patient was discharged without neurological deficits, and early and late follow-up angiography disclosed successful removal of the aneurysm and a patent bypass graft. We conclude that STA-MCA bypass and aneurysm excision is a successful treatment method for a giant serpentine aneurysm.
Two Cases of Twenty - Nail Dystrophy
Lee, Kang Seok,Ro, Byung In,Lim, Hyun Sang,Seo, Seong Jun,Hong, Chang Kwun 대한피부과학회 1999 Annals of Dermatology Vol.11 No.2
Twenty-nail dystrophy is an idiopathic nail dystrophy in which all twenty nails are uniformly and simultaneously affected with excess longitudinal ridging and loss of lustre. The pathogenesis is controversial, and the treatment is unsuccessful. It is thought to have a self-limiting and reversible nature when it develops in childhood, but in adults, it is unusual and exists persistently. We report here two cases of adult patients with dystrophy of all twenty nails, whose ages were 58 and 55. The disease had been present for one year and may be associated with alopecia areata in the 58 year old and an idiopathic condition in the 55 year old. Negative results were obtained on mycological studies. Biopsies taken from the nail bed revealed marked hyperkeratosis consistent with nail dystrophy.

Background/Aims: The aim of this study was to evaluate whether the mucosa-tracking technique is effective for improving precutting-related pancreatitis and the sustained failure of bile duct cannulation in precut papillotomy (PP) with the Iso-Tome (MTW Endoskopie). Methods: From September 2004 to June 2006, PP was performed with the Iso-Tome if biliary cannulation failed by conventional methods for approximately 5 minutes. The pink intrapapillary mucosa (PIPM) exposed by PP was tracked and classified into four groups: fully exposed and oriented to the direction of the bile duct (group A) or the pancreatic duct (group B), partially exposed (group C), or unexposed (group D). The success rate of bile duct cannulation (SRBC), the procedure time required for successful bile duct cannulation (PTBC), and the complications in the first session were compared between the mucosa-exposed groups (MEGs; group A, B, and C) and the mucosa-unexposed group (MUEG; group D). Results: A total of 59 patients (25 females, 34 males) with a mean age of 65.2 years were enrolled. The MEGs and MUEG comprised 52 (88.1%) and 7 (11.9%) patients, respectively. SRBC in the first session was 86.4% (51/59) in total and 92.3% (48/52) in the MEGs, compared to only 42.9% (3/7) in the MUEG (p=0.005). The mean PTBC in the MEGs and MUEG was 8.7 minutes and 16.3 minutes, respectively (p=0.23). Complications occurred in 6.8% of the patients (4/59; all pancreatitis); there were no differences between the MEGs (5.8%, 3/52) and MUEG (14.3%, 1/7; p=0.41). All four patients with pancreatitis were managed medically. Conclusions: The mucosa-tracking technique in PP with the Iso-Tome is a feasible and useful method of enhancing SRBC. PIPM is an important endoscopic landmark for successful PP. (Gut Liver 2010;4:76-83)
A Case of Disseminated Cutaneous Metastatic Carcinoma from Stomach Carcinoma
Lee, Kang Seok,Ro, Byung In,Lim, Hyun Sang,Seo, Seong Jun,Hong, Chang Kwun 대한피부과학회 1998 Annals of Dermatology Vol.10 No.2
We report a case of disseminated cutaneous metastatic carcinoma from stomach carcinoma in a 66-year-old male who complained chiefly of widespread cutaneous nodules. He had been admitted to the Department of Internal Medicine for stomach carcinoma. A radiological examination revealed a diffuse stomach wall thickening from the fundus to the antrum, and enlargement of paraaortic and pericaval lymph nodes during an abodominal CT scan. The clinical findings manifested above may suggest cutaneous metastasis from stomach carcinoma. A histological examination of the skin and stomach biopsies showed atypical cells with pleomorphic, hyperchromatic nuclei and bubble-like cytoplasm, which are consistent with poorly differentiated adenocarcinoma. Immunohistochemical stainings showed that these cells were positive for epithelial membrane antigen (EMA), carcinoembryonic antigen (CEA) and low molecular weight cytokeratin.

Background Postmastectomy adjuvant therapy is used to prevent locoregional recurrence and improve overall breast cancer specific survival rates. However, it can adversely affect the cosmetic results of reconstruction. Therefore, the authors examined flap stability and patients' satisfaction with immediate breast reconstruction after adjuvant therapy. Methods We retrospectively reviewed the medical records of 204 patients from January 2006 to November 2011. For complication rates, the authors categorized the patients who underwent the immediate breast reconstruction into 4 groups: adjuvant chemotherapy and radiotherapy group, adjuvant chemotherapy only group, adjuvant radiotherapy only group, and the group that did not undergo adjuvant therapy. For comparison of patients' satisfaction, the study was performed with an additional 16 patients who had undergone delayed breast reconstruction. Results Regarding complication rates, the group that had undergone adjuvant therapy showed no significant difference compared to the group that did not undergo adjuvant therapy. In evaluating the patients' satisfaction, there was no significant difference. Conclusions Even after adjuvant therapy, immediate breast reconstruction showed good results with respect to flap stability and patients' satisfaction. Immediate breast reconstruction and adjuvant therapy is a safe and useful option for breast cancer patients.
