We report the findings of a patient with an asymptomatic Arc of Buhler (AOB) aneurysm, which was successfully treated by transcatheter coil embolization. An abdominal CT and angiography revealed an intact pancreaticoduodenal artery arcade (PDAA) and an anomalous communication between the SMA and celiac axis, termed an AOB. An aneurysm was observed at the origin of the AOB and treated with a transcatheter embolization using coils. A follow-up CT imaging confirmed the total occlusion of the aneurysm with a patent PDAA. The successful results of this treatment suggest that the endovascular therapy of an AOB aneurysm with a celiac axis occlusion and an intact PDAA is feasible and safe.

Colorectal cancer is a common cancer; generally, adults aged ≥ 50 years are screened using stool occult blood tests and colonoscopy. However, colorectal adenoma and cancer have been found in patients under the aged of 50, and studies on characteristics and risk factors in young patients are lacking. We evaluated the prevalence and risk factors of colorectal adenoma and cancer in young adults aged under 50 years.We retrospectively analyzed 570 individuals aged under 50 years who underwent colonoscopy at the Haeundae Paik Hospital, Korea, from January to June 2018. Logistic regression model was used to identify the risk factors for colorectal adenoma and colorectal cancer.The prevalence of colorectal adenoma in group of 19-29 years was 3.2% (1 of 31), 30-39 years was 13.8% (30 of 217) and in the group of 40-49 years was 21.1% (68 of 322) (P = .009). In multivariable analysis, age over 45 years (adjusted odds ratio [OR], 1.941; 95% confidence interval [CI], 1.187-3.172; P = .008) and male sex (adjusted OR, 1.711; 95% CI, 1.044-2.806; P = .033) were independent risk factors for colorectal neoplasia including cancer.The prevalence of colorectal adenoma increases as the age increased in young adults under 50 years of age, especially after the age of 45 years, the risk of colorectal neoplasia increases; hence, early screening should be considered before the age of 50 years.

Purpose:To evaluate the long-term changes in the corneal sensitivity and to analyze which tear film parameters correlate with corneal sensitivity after penetrating keratoplasty (PKP). Methods: Twenty-eight eyes of 28 patients who underwent PKP were included in the present study. Corneal sensitivity, Schirmer test, tear break-up time, tear clearance rate, and keratoepitheliopathy were evaluated at 1, 3, 6, 12, and 24 months postoperatively. Then, which tear film parameters correlated with corneal sensitivity during the follow-up period were analyzed. Results: Corneal sensitivity was 5.18 ± 3.96 mm at one month postoperatively and increased to 29.64 ± 12.39 mm (p < 0.05) at 24 months postoperatively but was still not in the normal range. Tear break-up time and keratoepitheliopathy improved at postoperative three months and six months, respectively, compared with one month postoperatively, and both measures normalized at 24 months postoperatively. Schirmer test results and tear clearance rate were in the normal range during the follow-up period. Corneal sensitivity was correlated with tear break-up time from three to 24 months postoperative and with tear clearance rate from one month to 24 months postoperative (p < 0.05). Conclusions: Change in corneal sensitivity after penetrating keratoplasty correlates with tear break-up time and tear clearance rate; therefore, tear break-up time and tear clearance rate can be used as parameters for management of dry eye after PKP.

The diagnosis of fixed drug eruption is straightforward because of characteristic findings, including recurrence of similar lesions at the same site and healing with residual hyperpigmentation. However, generalized or multiple fixed drug eruption, a rare variant form, can be a diagnostic challenge. Acebrophylline is a widely prescribed oral bronchodilator with mucosecretolyic and anti-inflammatory activity and is known to be relatively safe. A 34-year-old woman presented with recurrent numerous erythematous patches after ingestion of cold medications containing clarithromycin, loxoprofen, acebrophylline, and pseudoephedrine. Skin biopsy results showed vacuolar degeneration of the basal cell layer, scattered necrotic keratinocytes in the epidermis, and perivascular lymphohistiocytic infiltration in the upper dermis. A patch test showed negative results. However, in an oral challenge with acebrophylline 3 hours later, lesions reappeared at the same sites. To the best of our knowledge, this is the first case report of acebrophylline-induced generalized fixed drug eruption. (Allergy Asthma Respir Dis 2017;5:298-301)
