The Peutz-Jeghers syndrome has three cardinal features: gastrointestinal polypasis, mucocutaneous piginentation and autosomal dominant heredity. This syndrome is ciinically important because of the complication caused by the gastrointestinal ployp, leading to abdominal pain, gastrointestinal bleeding and intussusception. We experienced a case of Peutz-Jeghers syndrome who complained of dizziness, vague abdominal pain, melanin pigmentations of the lips, oral mucosa and digits and reported with the review of the literature.

INTRODUCTIONRenal infarction is a rare and easily missed disease. There is even less meaningful information on renal infarction in the Asian population. Thus, the aim of this study was to clarify the clinical characteristics of the disease in Asian patients.

CLINICAL PICTUREOver a period of 10 years, 38 Chinese patients with renal infarction diagnosed by contract-enhanced CT or angiography were enrolled in this study. Their demographic data, clinical characteristics, laboratory and image results, risk factors or suspected causes, treatment and final outcomes were retrospectively reviewed. The results were also compared with the analogous Western data. The mean age of the sample population was 60.8 +/- 17.6 years, with patients aged over 50 years and males predominating. The most common symptoms/signs were abdominal (57.9%) and flank pain/tenderness (50%). Only 23.7% of patients had suffered previous thromboembolic events such as coronary or peripheral artery diseases, or cerebral infarction. Cardiogenic factors, such as atrial fibrillation, intra-cardiac thrombus, infective endocarditis and valvular heart disease, were the main causes of renal infarction (57.9%). The most common laboratory abnormalities were elevated serum LDH (92.1%) and proteinuria (76.3%). Only half of the cases involved haematuria at initial presentation.

TREATMENT AND OUTCOMEOne-third of the sample suffered renal impairment after the renal infarction. Overall mortality rate during admission was 13.2% (n = 5). The cause of death was usually not the renal infarction itself but rather the underlying disease and its complications. There was no difference in outcome for anticoagulation treatment with or without thrombolytics. Compared to their Western counterparts, the proportion of males (71.1% versus 48.3%) and bilateral renal infarctions (31.6% versus 12.4%) were significantly higher, and the percentage of leukocytosis (50% versus 85%) significantly lower in our Asian patients.

CONCLUSIONClinical presentation of renal infarction is usually non-specific and differs for Asian and Western populations. In our Asian patients, the most common clinical characteristics were abdominal pain/tenderness, flank pain/tenderness, elevated serum LDH and proteinuria. Early diagnosis and treatment are imperative because of the high rate of renal impairment and associated mortality. If this disease is suspected, contrast-enhanced CT is suggested to exclude or confirm renal infarction and anticoagulation alone is currently the favored treatment.

OBJECTIVEAccuracy of diagnostic methods for detecting Helicobacter pylori (H. pylori) infection among patients with bleeding peptic ulcers has not been thoroughly investigated. The aim of this study was to compare the diagnostic tests and their combined usage in detection of H. pylori infection in patients with bleeding gastric ulcers and without the use of nonsteroidal anti-inflammatory drugs.

METHODSA total of 57 patients who presented with bleeding gastric ulcers by endoscopy were enrolled. The status of H. pylori was identified by performing the rapid urease test (RUT), histology and (13)C-labeled urea breath test (UBT). The criteria for having H. pylori infection was a minimum of two positive tests.

RESULTSThe prevalence of H. pylori infection in our patient group was 80.7%. Among the three tests used: RUT, histology, and UBT, sensitivities were 56.5%, 97.8% and 100%, while specificities were 100%, 45.5% and 81.8%, respectively. The overall accuracies of the tests were 78.3%, 71.6% and 90.9%, respectively. Although UBT obtained significantly higher accuracy than histology (P = 0.02) as opposed to RUT (P = 0.11), UBT had significantly higher sensitivity than RUT (P < 0.001). In terms of combining any two of the three tests, more accuracy (98.9%) was achieved when both UBT and histology were used to confirm the diagnosis of the other. Conversely, failure to use combined tests generated the potential of missing a proper H. pylori diagnosis.

CONCLUSIONSUBT is superior to the other two tests in bleeding gastric ulcers. RUT lacks sensitivity for detection of H. pylori infection. However, the concomitant use of UBT and histology seems to be more accurate when gastric ulcers present with bleeding.
