The endoscopic fine needle aspiration cytology may add to the diagnostic accuracy of endoscopic biopsy and brush cytology. It is also of particular value in submucosal, infiltrative and ulceronecrotic tumors. Endoscopic fine needle aspiration cytology was done with sclerotherapy needle(23 gauge) in. the 17 patients with submucosal tumor(18 cases), extrinsic compression(2 cases), infiltrative gastric cancer(one case) and cancer of the ampulla of Vater(one case) on the upper gastrointestinal endoscopy. Endoscopic fine needle aspiration cytology established the diagnosis in 6 cases(submucosal tumor of the stomach; 2 cases, submucosal tumor of the duodenum; one case, extrinsic mass of the duodenum; one case, infiltrative cancer of the stomach; one case, and the cancer of ampulla of Vater; one case) of 17 cases. There were negative results for malignancy in 7 cases and material insufficiency in 4 cases. Five cases of the positive results with endoscopic fine needle aspiration cytology were not diagnosed with endoscopic forceps biopsies. There was no complication. We conclude that endoscopic fine needle aspiration cytology is a simple and safe technique and is of particular value in submucosal tumor, extrinsic compression of the upper gastrointestinal tract by tumor, and infiltrative gastric cancer.

Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gastrointestinal tract with an unknown etiology and pathogenesis. The incidence and prevalence of IBD are increasing rapidly in Korea. Approximately one-third of patients with IBD appear to develop extra-intestinal manifestations with the skin being one of the most commonly affected organs. They may precede, occur simultaneously, or follow the diagnosis of IBD. In addition, they may parallel with the luminal symptoms or independent from the disease activity of IBD. This review outlines the skin manifestations associated with IBD and discusses their management. Skin manifestations should be managed in close collaboration with a dermatologist.

Stroke in young adults is uncommon and may require extensive evaluation to elucidate an underlying cause. A 21- year-old male professional golfer experienced left side weakness, dysarthria, headache during golfing. Magnetic resonance imaging (MRI) revealed broad ischemia on right basal ganglia, frontal and temporal lobes. Magnetic resonance angiography (MRA) and 4-vessel angiography revealed beading of right intracranial internal carotid and middle cerebral arteries which suggests fibromuscular dysplasia. We report a case of intracranial fibromuscular dysplasia without renal involvement resulting in cerebral infarction in young male professional golfer.

Purpose: To evaluate the accuracy of MRI in predicting the pathological complete response (pCR) and the residual tumor size of breast cancer after neoadjucant chemotherapy (NAC), and to determine the factors affecting the accuarcy. Materials and Methods: Eighty-eight breast cancer patients who underwent surgery after NAC at our center between 2010 and 2017 were included in this study. pCR was defined as the absence of invasive cancer on pathological evaluation. The maximum diameter of the residual tumor on post-NAC MRI was compared with the tumor size of the surgical specimen measured pathologically. Statistical analysis was performed to elucidate the factors affecting pCR and the residual tumor size-discrepancy between the MRI and the pathological measurements. Results: The pCR rate was 10%. The diagnostic accuracy of MRI and the area under the curve for predicting pCR were 90.91% and 0.8017, respectively. The residual tumor sizes obtained using MRI and pathological measurements showed a strong correlation (r = 0.9, p < 0.001), especially in patients with a single mass lesion (p = 0.047). The size discrepancy between MRI and the pathological measurements was significantly greater in patients with the luminal type (p = 0.023) and multifocal tumorson-mass enhancement on pre-NAC MRI (p = 0.047). Conclusion MRI is an accurate tool for evaluating pCR and residual tumor size in breast cancer patients who receive NAC. Tumor subtype and initial MRI features affect the accuracy of MRI.

Purpose: Analyses on pure laparoscopy in donor hepatectomies, including the middle hepatic vein (MHV), are still scarce. This study aimed to compare the outcomes of donor right hepatectomy, including the MHV, when performed laparoscopically with conventional open surgery. Methods: Data from living donors who underwent donor right hepatectomy between January 2012 and December 2020 were retrospectively analyzed. The intraoperative and postoperative complication rates of the pure laparoscopic donor right hepatectomy (PLDRH) with MHV inclusion (PLDRHM) group were compared with the conventional open donor right hepatectomy with MHV inclusion (CDRHM) group and the PLDRH without MHV inclusion [PLDRHM(–)] group. Results: Compared to the CDRHM group, the PLDRHM group had a longer bench time (P < 0.001) and higher Δ%,calculated as [(preoperative value – postoperative value)/preoperative value] × 100, of AST (P < 0.001), ALT (P < 0.001), and total bilirubin (P = 0.023), but shorter hospital stay (P = 0.004) and a lower rate of complications (P = 0.005). Compared to the PLDRHM(–) group, the PLDRHM group had fewer male donors (P < 0.001) and a lower body mass index (P < 0.001), estimated total liver volume (P < 0.001), and real graft weight (P < 0.001). Results of laboratory changes, hospital stays, and complication rates were similar between the 2 groups. Conclusion PLDRH with the inclusion of the MHV in selected donors and recipients is feasible and safe when performed by surgeons experienced in laparoscopic surgery, with favorable complication rates compared to CDRHM and PLDRHM(–).

BACKGROUND: Multiple therapies involving ablative and nonablative techniques have been developed for the rejuvenation of photodamaged skin. Radiofrequency (RF) is emerging as a gentler, nonablative skin-tightening device that delivers uniform heat to the dermis at a controlled depth. OBJECTIVE: To compare the efficacy of bipolar radiofrequency (Polaris™) and 1,550-nm fractional erbium-glass laser (Mosaic™) for the treatment of photoaging using a randomized, split-face, patient- and evaluator-blind study. METHODS: We evaluated the clinical effects after the treatment of photoaging. Ten Asian women (Fitzpatrick skin type III to IV) underwent 9 weeks of treatment (3 sessions at 3-week intervals) with monotherapy (Polaris™) on one side of the face and combination therapy with non-ablative bipolar radiofrequency (Polaris™) and 1,550-nm fractional erbium-glass laser (Mosaic™) on the other side. RESULTS: Among 10 patients, 4 were male and 6 were female. Subjective and objective assessments showed that the combination therapy was more effective. As the number of the treatment sessions increased, there was an accompanying increase in the satisfaction level and efficacy. CONCLUSION: This study suggests that bipolar radiofrequency combined with 1,550-nm fractional erbium-glass laser could be effective treatment for photoaging.
