The diagnosis of exogenous ochronosis is often challenging and requires a high index of suspicion. Herein, we report a case of exogenous ochronosis in a Chinese patient. The condition was caused by the use of bleaching agents, including creams containing hydroquinone. We demonstrate the use of dermoscopy as an invaluable tool for the early recognition of the condition, as well as in the selection of an appropriate site for a skin biopsy.

OBJECTIVESTo probe into the complications of prostate biopsy.

METHODSThe clinical data of 220 patients underwent prostate biopsy from 1997 to 2001 were reviewed.

RESULTSA total of 93 patients suffered slight complications, and 15 patients suffered severe complications.

CONCLUSIONSTransrectal prostate biopsy is easily and safely by using 18 gague biopsy needles. These data demonstrate the low morbidity and less complication associated with contemporary transrectal prostate biopsy.

OBJECTIVETo compare the difference of mucosal damage in the remnant esophagus with similar postoperative reflux after esophagectomy and gastric interposition between Chinese and Canadian population.

METHODSA prospective 1 to 1 paired study based on the same surgical approach was performed in Medical Centre of University of Montreal and West China Hospital of Sichuan University during the period from September 2010 to October 2013. The patients were followed up and evaluated by reflux symptom scoring, endoscopic assessment of mucosal damage, pathologic examination of biopsies and proliferation index test of esophageal epithelium.

RESULTSEighteen Han Chinese and 18 Caucasian Canadian patients with esophagectomy and gastric interposition were included in this study, with a follow-up period of 45 (28-67) months. There were no significant differences between the two groups in the incidence of postoperative reflux symptom, reflux symptom scoring, histological reflux esophagitis, erosion or stricture of remnant esophagus (all P>0.05). However, the incidence of mucosal metaplasia [44.4% (8/18) versus 11.1% (2/18), P=0.026], quantitative MUSE scoring [1.5 (1.0-2.0) versus 1.0 (0-2.0), P=0.042] and proliferation index [0.40 (0.30-0.45) versus 0.35 (0.30-0.50), P=0.038] of esophageal epithelium were significantly higher in Canadian patients than those in Chinese patients.

CONCLUSIONUnder similar reflux situation, esophageal mucosa of Canadian population is more sensitive to the gastroesophageal reflux damage compared with Chinese population, resulting in more severe reflux damage of remnant esophagus in Canadian patients.

The diagnostic value of core needle biopsy is increasingly being preferred because of its better characterization of benign and malignant lesions and lower frequency of insufficient samples. The aim of this study was to determine the diagnostic accuracy and complication rates with 2 different gauges of core biopsy needle in the preoperative diagnosis of palpable breast lumps. A total of 150 consecutive core biopsies were included in this prospective non-randomised study of palpable breast lump from May 2000 to May 2001. The tissue diagnosis made from the core biopsy specimen was compared with the final histopathology reports from the excised specimen. However, if the lump is not excised, a presumptive diagnosis of benign lesion was made only after at least 6 months follow up with no change in the breast lump. The data were analysed for sensitivity, specificity, predictive values, diagnostic accuracy and complications. The results from the 2 different sizes of core needle biopsies were compared accordingly and a statistical analysis was performed using Chi-squared test. Ninety-six core specimens were acquired with 14 G needle while the other 54 with 16 G needle. There was no significant statistical difference between the accuracy of both needle sizes. However, 4 complications occurred with the larger size 14 G needle while none with the 16 G needle, but this was not statistically significant. In conclusion the size 16 G core biopsy needle provided an accurate diagnostic reliability that is comparable to the larger size 14 G needle in the preoperative diagnosis of palpable breast lump.

Drug-induced liver injury (DILI) remains a significant clinical challenge and is the leading cause of acute liver failure in most countries. An aging population that uses more medications, a constant influx of newly developed drugs and a growing risk from unfamiliar herbal and dietary supplements will make DILI an increasing part of clinical practice. Currently, the most effective strategy for disease management is rapid identification, withholding the inciting agents, supportive care and having a firm understanding of the expected natural history. There are resources available to aid the clinician, including a new online "textbook" as well as causality assessment tools, but a heightened awareness of risk and the disease's varying phenotypes and good history-taking remain cornerstones to diagnosis. Looking ahead, growing registries of cases, pharmacoepidemiology studies and translational research into the mechanisms of injury may produce better diagnostic tools, markers for risk and disease, and prevention and therapeutics.
