Peripapillary duodenal varices as a rare cause of severe bleeding in a patient with no other signs of portal hypertension--successful endoscopic treatment with cyanoacrylate injection

Duodenal varices (DVs) are a rare cause of upper gastrointestinal bleeding and rather suspected in patients with portal hypertension. Bleeding DVs are difficult to manage and often fatal due to delayed diagnosis. We report on a 71-year-old patient with massive upper gastrointestinal haemorrhage, who did not show any clinical signs of portal hypertension; however, he had a history of duodenal segmental resection 8 years before. The source of bleeding could not be detected with different imaging methods such as angiography and computed tomography. Upper gastrointestinal endoscopy finally revealed DVs, which were located just adjacent to the papilla. After endoscopic injection therapy with n-butyl 2-cyanoacrylate the bleeding stopped immediately and the patient soon stabilised. Despite the peripapillar localisation no signs of pancreatitis or cholestasis occurred; during 10-month follow-up a marked regression of the varices without further signs of variceal bleeding was observed.     

Relation of risk factors and putative premotor markers for Parkinson’s disease

As both risk and premotor markers are increasingly discussed to play a key role in the pre-diagnostic phase of Parkinson’s disease (PD) the aim of this study was to determine the relation between the risk factors hyperechogenicity of the substantia nigra (SN+) and/or positive family history of PD (faPD+) and putative premotor markers for PD. In a cross-sectional analysis of data of the PRIPS cohort, 1,149 volunteers older than 50 years free of PD were included. In addition to the risk factors SN+ and faPD+, olfactory dysfunction was tested using the Sniffin’ sticks test and motor examination was performed. History of depression and constipation was evaluated by a semi-structured interview. Of all 1,149 individuals, 880 had none of the risk markers (76.6%), 143 persons (12.4%) had SN+, 84 (7.3%) were classified as faPD+ and 42 (3.7%) persons had both risk factors. Volunteers with SN+ showed olfactory dysfunction and mild motor impairment (p ≤ 0.001) more often. Depression was more prominent in individuals having two risk factors (p = 0.05). An accumulation of premotor markers was seen in the SN+ group with or without concomitant faPD+, but not in persons with faPD+ only. The profile of premotor markers seems to differ in participants having SN+ and/or faPD+, with SN+ showing the overall highest association with most premotor markers, which implies that SN+ might be a strong indicator for a neurodegenerative process.     

Survival analysis of breast cancer liver metastasis treated by hepatectomy: A propensity score analysis for Chinese women in Hong Kong

Background: Survival of patients with breast cancer liver metastasis is very poor. This study aimed to analyze the survival outcome of hepatectomy for this patient population. Methods: From January 1995 to December 2014, 2522 patients with liver cancer received hepatectomy at our hospital. Twenty-one of them, all female, received the operation for breast cancer liver metastasis. Performance was compared with patients with colorectal liver metastasis treated with hepatectomy after propensity score analysis in a ratio of 1:3. Results: Twenty-one patients received hepatectomy for breast cancer. After propensity score matching, 63 patients who had hepatectomy for colorectal cancer were selected for comparison. There was no significant difference in immediate or short-term outcomes between the two groups of patients in terms of operative time, blood loss and surgical morbidities. All patients with breast cancer had R0 resection. No hospital death occurred. After hepatectomy, the 1-, 3-and 5-year overall survival rates were 100.0%, 58.9% and 58.9% respectively in patients with breast cancer. The 1-, 3-and 5-year overall survival rates were 95.0%, 57.2% and 39.7% respectively in patients with colorectal cancer( P = 0.572). On multivariate analysis, triple negative status was the only independent poor prognostic factor in breast cancer liver metastasis(OR = 6.411; 95% CI: 1.351–30.435; P = 0.019). Conclusions: Hepatectomy is a safe and effective way of treating breast cancer liver metastasis at experienced centers where multidisciplinary adjuvant treatments are available. It can be considered more frequently as part of the multidisciplinary care for this patient population.     

Microdeletion 20p12.3 involving BMP2 contributes to syndromic forms of cleft palate

Orofacial clefts of the lip and/or palate comprise one of the most common craniofacial birth defects in humans. Though a majority of cleft lip and/or cleft palate (CL/P) occurs as isolated congenital anomalies, there exist a large number of Mendelian disorders in which orofacial clefting is part of the clinical phenotype. Here we report on two individuals and one multi-generational family with microdeletions at 20p12.3 that include the bone morphogenetic protein 2 (BMP2) gene. In two propositi the deletion was almost identical at ～600 kb in size, and BMP2 was the only gene deleted; the third case had a ～5.5-Mb deletion (20p13p12.2) that encompassed at least 20 genes including BMP2. Clinical features were significant for cleft palate and facial dysmorphism in all three patients, including Pierre-Robin sequence in two. Microdeletion 20p13p12 involving BMP2 is rare and has been implicated in Wolff-Parkinson-White (WPW) syndrome with neurocognitive deficits and with Alagille syndrome when the deletion includes the neighboring JAG1 gene in addition to BMP2. Despite a significant role for the BMPs in orofacial development, heterozygous loss of BMP2 has not been previously reported in patients with syndromic clefting defects. Because BMP2 was the sole deleted gene in Patients 1 and 2 and one of the genes deleted in Patient 3, all of whom had clinical features in common, we suggest that haploinsufficiency for BMP2 is a crucial event that predisposes to cleft palate and additional anomalies. Lack of significant phenotypic components in family members of Patient 1 suggests variable expressivity for the phenotype.
