A 6-year-old intact male Maltese dog presented with a history of blindness and ataxia. Neuro-ophthalmic examination revealed dilated pupils with absent pupillary light reflexes and menace response in both eyes. Mild peripapillary edema was noted in the fundus of the right eye. After magnetic resonance imaging, the dog was provisionally diagnosed with meningoencephalitis of unknown etiology. Follow-up funduscopy was performed to monitor the condition of the optic discs for three years. Despite of the treatment with prednisolone, the optic nerve progressed to atrophy and the dog couldn't restore vision.

Since the introduction of pancreas transplantation more than 40 years ago, surgical techniques and immunosuppressive regiments have improved and both have contributed to increase the number and success rate of this procedure. However, graft survival corresponds to early diagnosis of organ-related complications. Thus, knowledge of the transplantation procedure and postoperative image anatomy are basic requirements for radiologists. In this article, we demonstrate the imaging spectrum of pancreas transplantation with enteric exocrine drainage.

OBJECTIVETo investigate the inhibitory effects of curcumin against HeLa cell invasion and migration and explore the underlying mechanisms.

METHODSHeLa cells were exposed to curcumin treatment at the concentrations of 0, 10, 25, 50, 100, 150 and 200 µmol/L for 24 h. MTT and TUNEL assays were used to assess the cell proliferation inhibition and apoptosis, respectively. Transwell assay was used to evaluate the invasiveness and migration of the treated cells, and RT-PCR and Western blotting were employed to detect the changes in the expression of inducible nitric oxide synthase (iNOS), and MMP-9 and E-cad, the 2 markers of cell invasion and migration, were detected by Western blotting. The capacity of NO production in HeLa cells was measured by Griess method.

RESULTSCurcumin inhibited the proliferation of HeLa cells by inducing cell apoptosis in a concentration-dependent manner. Curcumin inhibited the invasion and migration of HeLa cells by increasing E-cad expression and decreasing MMP-9 expression, and also decreased the expression level of iNOS and NO production in the cells.

CONCLUSIONCurcumin inhibits the invasion and migration of HeLa cells by decreasing the expression of iNOS.

A 39-year-old woman, who 3 months prior had undergone sono-guided biopsy for pelvic masses, was admitted to our hospital with dyspnea. After the procedure, a large arteriovenous (AV) fistula was detected. The patient developed dyspnea with pain and swelling of the right leg and subsequently visited our hospital. Multiple cafe-au-lait spots and subcutaneous nodules were noted and a continuous bruit was heard in the right pelvic area. Transthoracic echocardiography revealed marked dilatation of the right atrium, right ventricle, and inferior vena cava. An angiogram showed multiple AV fistulas between the right iliac arteries and veins. The patient underwent aortoiliofemoral bypass surgery. Follow-up echocardiography after surgery showed dramatic improvement in heart function. Molecular analysis revealed a novel variation (c.4270-1G>a) at the 24th intron-exon splicing consensus sequence of the neurofibromin 1 (NF1) gene. This is a rare case of AV fistula that developed after biopsy and caused right-sided heart failure in a patient with neurofibromatosis.

Schistosomiasis is one of the important neglected tropical diseases (NTDs) in Tanzania, particularly in Lake Victoria zone. This baseline survey was a part of the main study of integrated control of schistosomiasis and soil-transmitted helminths (STHs) aimed at describing morbidity patterns due to intestinal schistosomiasis among adults living on Kome Island, Sengerema District, Tanzania. Total 388 adults from Kome Islands (about 50 people from each village) aged between 12 and 85 years, were examined by abdominal ultrasound according to the Niamey protocol. Liver image patterns (LIPs) A and B were considered normal, and C-F as distinct periportal fibrosis (PPF). The overall prevalence of PPF was 42.2%; much higher in males than in females (47.0% in male vs 34.4% in females, P=0.007). Abnormal increase of segmental branch wall thickness (SBWT) and dilated portal vein diameter (PVD) were also more common in males than in females. Hepatosplenomegaly was frequently encountered; 68.1% had left liver lobe hepatomegaly and 55.2% had splenomegaly. Schistosoma mansoni-related morbidity is quite high among adults in this community justifying the implementation of integrated control strategies through mass drug administration, improved water supply (pumped wells), and health education that had already started in the study area.

The objective of this study was to carry out a community survey on schistosomiais and soil-transmitted helminth (STH) infections in order to suggest feasible and effective intervention strategies in Lake Victoria basin, Tanzania. A total of 37 communities selected from 23 districts of the 4 regions in the Lake Victoria basin of Tanzania were involved in the study. From each of the selected locality, 50 adult community members, 25 males and 25 females, were recruited for the study. Each study participant was requested to submit stool and urine specimens. From each stool specimen, duplicate Kato-Katz thick smears were prepared and microscopically examined for Schistosoma mansoni and STH eggs. Urine specimens were processed by the filtration technique and microscopically examined for Schistosoma haematobium eggs. Ultrasound examination for morbidity due to schistosomiasis was performed. Mass treatment was done using praziquantel and albendazole for schistosome and STHs infections, respectively. Out of 1,606 adults who provided stool specimens, 199 (12.4%) were positive for S. mansoni, 349 (21.7%) for hookworms, 133 (8.3%) for Ascaris lumbricoides, and 33 (2.0%) for Trichuris trichiura. Out of 1,400 participants who provided urine specimens, 25 (1.8%) were positive for S. haematobium eggs. Because of the co-endemicity of these afflictions and their impact on vulnerable population groups, the helminthiasis could be simultaneously treated with 2 drugs, praziquantel for schistosomiasis and albendazole for STHs.

The objectives of this study was to conduct a survey on schistosomiasis and soil-transmitted helminth (STH) infections in order to come up with feasible control strategies in Lake Victoria basin, Tanzania. Depending on the size of the school, 150-200 schoolchildren were recruited for the study. Duplicate Kato-Katz stool smears were prepared from each child and microscopically examined for Schistosoma mansoni and STHs. Urine specimens were examined for Schistosoma haematobium eggs using the filtration technique. After the survey, mass drug administration was done using praziquantel and albendazole for schistosomiasis and STHs infections, respectively. A total of 5,952 schoolchildren from 36 schools were recruited for the study and had their stool and urine specimens examined. Out of 5,952 schoolchildren, 898 (15.1%) were positive for S. mansoni, 754 (12.6%) for hookworms, 188 (3.2%) for Ascaris lumblicoides, and 5 (0.008%) for Trichuris trichiura. Out of 5,826 schoolchildren who provided urine samples, 519 (8.9%) were positive for S. haematobium eggs. The results revealed that intestinal schistosomiasis, urogenital schistosomiasis, and STH infections are highly prevalent throughought the lake basin. The high prevalence of intestinal and urogenital schistosomisiasis in the study area was a function of the distance from Lake Victoria, the former being more prevalent at localities close to the lake, whilst the latter is more so away from it. Control of schistosomiasis and STHs in the study area requires an integrated strategy that involves provision of health education to communities, regular treatments, and provision of adequate safe water supply and sanitation facilities.

BACKGROUND AND OBJECTIVES: Coronary artery calcium (CAC) scoring in the asymptomatic population can improve cardiovascular risk prediction. We aimed to assess CAC progression and the impact of coronary risk factors on the CAC progression rate in asymptomatic Korean individuals with a baseline CAC score of zero. METHODS: The study population was derived from the Korea Initiatives on Coronary Artery Calcification (KOICA) registry: a retrospective, single ethnicity, multicenter registry of asymptomatic individuals who underwent CAC scoring as a part of a health checkup. Individuals with at least two CAC scores and an initial score of zero were included. CAC progression was defined as [√CAC score (follow-up) − √CAC score (baseline)] ≥2.5. The 10-year atherosclerotic cardiovascular disease (ASCVD) risk was calculated. RESULTS: Among 6,268 participants (mean age, 48.0±7.1 years; male, 80.5%), 719 (11.5%) experienced CAC progression during follow-up (median, 109 months; interquartile range, 78–208 months). The CAC progression rate was 0.3%, 1.9%, 4.3%, 8.6%, and 16.7% in years 1–5, respectively. The chance of CAC progression at 5 years was 13.1%, 22.0%, and 27.9% for individuals with a 10-year ASCVD risk of <5%, ≥5% but <7.5%, and ≥7.5%, respectively. A multivariable analysis revealed age, male sex, waist circumference, diabetes, and low-density lipoprotein cholesterol level as independently associated with annualized CAC progression (p<0.001, p=0.017, p=0.025, p=0.032, and p=0.003, respectively). CONCLUSIONS: The probability of CAC progression is very low in Korean individuals with a CAC score of zero. However, the risk of CAC progression increases nonlinearly over time, and increases as the 10-year ASCVD risk increases.

Adverse reactions of subcutaneous low molecular weight heparin or unfractionated heparin could be complications by bleeding, heparin-induced thrombocytopenia, drug-induced liver injury, osteoporosis, and cutaneous reactions. Heparin-induced skin lesions vary from allergic reactions like erythema, urticaria, eczema to intradermal microvascular thrombosis associated with heparin-induced thrombocytopenia. There is a rare cutaneous complication, called bullous hemorrhagic dermatosis. We experienced this rare case of the cutaneous complication caused by enoxaparin. Several tense bullous hemorrhagic lesions occurred after 3 days of enoxaparin in a known bullous pemphigoid patient who had aortic valve replacement surgery with a mechanical prosthesis. The bullous hemorrhagic lesions were regressed after the discontinuation of enoxaparin but recurred after re-administration. The lesions were controlled by the administration of systemic corticosteroid and alternative anticoagulant. To date, less than 20 cases have been reported worldwide. This is the first case of bullous hemorrhagic dermatosis induced by enoxaparin, a low-molecular-weight heparin in Korea. This is also the first case of bullous hemorrhagic dermatosis in a known bullous pemphigoid patient.
