Groups at risk for intestinal helminth infestation include international students and travelers, migrant laborers, refugees, children of foreign adoptions and the homeless. Symptoms are often minimal or vague, yet many such infections carry significant long-term morbidity. Enterobius vermicularis, the common pinworm, is usually manifested in children as anal itching and is best diagnosed by using the cellophane-tape test to recover eggs from the perianal skin. Treatment with mebendazole is indicated for the entire family. Trichuris, or whipworm, infection may be found with Ascaris infection, but whipworms are longer-lived and more likely to produce symptoms that mimic those of inflammatory bowel disease. Treatment for these parasites is mebendazole. Other significant helminthic infections, which are currently more common in immigrant populations, include hookworms (Necator americanus, Ancylostoma duodenale), threadworms (Strongyloides) and various tapeworms (Taenia, Diphyllobothrium and Hymenolepis species).

Primary sclerosing cholangitis (PSC) remains a disease of unknown etiology. The close association of PSC and inflammatory bowel disease (IBD), especially ulcerative colitis (UC), has been reconfirmed in numerous studies. Much has been learned about the pathogenesis, although the specific cause remains unknown. Copper overload and chronic hepatic bacterial infection have virtually been excluded as causes of PSC. Cytomegalovirus and reovirus remain under investigation. Familial clustering and HLA subtype similarities are seen in PSC with and without IBD. The finding of antineutrophil cytoplasmic antibodies (ANCA) in patients with PSC and those with UC suggests immunological features in the pathogenesis of PSC. Collected series of patients have better characterized clinical features of PSC. Endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC) have provided both diagnostic features and means of therapeutic intervention. Treatment of PSC is symptomatic (pruritus control and vitamin deficiency correction); or experimental (D-penicillamine, ursodeoxycholic acid [UDCA], methotrexate, or corticosteroids). Liver transplantation remains the ultimate treatment for end-stage PSC. Statistical analyses of clinical and laboratory variables in PSC help to determine prognosis and proposed timing for transplantation to achieve maximal longevity and quality of life. PSC affects middle-aged people and is expensive to treat over the natural course of the disease, making it an economically and medically important disease.

Primary sclerosing cholangitis (PSC) is a chronic, progressive cholestatic liver disease whose aetiopathogenesis is unknown. PSC is frequently associated with inflammatory bowel disease, in particular chronic ulcerative colitis, is most commonly observed in young males and is clinically characterized by fatigue, pruritus and jaundice. The diagnosis is supported by a cholestatic biochemical profile and histological abnormalities, and confirmed by visualization of an abnormal biliary tree. The natural history of the disease is currently being evaluated but is generally recognized to be slowly progressive, leading to complications of chronic cholestasis, portal hypertension and biliary cirrhosis. There is no specific medical treatment, and orthotopic liver transplantation remains the only definitive treatment for patients with end-stage PSC. A more rational approach to medical therapy will ensue upon a better understanding of the aetiopathogenesis of this disease.

The purpose of this study was to evaluate Soft Coated Wheaten Terriers (SCWTs) affected with protein-losing enteropathy (PLE) or protein-losing nephropathy (PLN) or both for allergy to food. We performed gastroscopic food-sensitivity testing, a provocative dietary trial, and measurement of fecal immunoglobulin E (IgE) in 6 SCWTs affected with PLE or PLN or both. Positive gastroscopic food-sensitivity test reactions were noted in 5 of 6 dogs. Positive reactions were found to milk in 4 dogs, to lamb in 2 dogs, and to wheat and chicken each in 1 dog. Adverse reactions to food (diarrhea, vomiting, or pruritus) were detected in all 6 dogs during the provocative dietary trial. Adverse reactions were found to corn in 5 dogs, to tofu in 3 dogs, to cottage cheese in 2 dogs, to milk in 2 dogs, to farina cream of wheat in 2 dogs, and to lamb in 2 dogs. Serum albumin concentrations significantly decreased and fecal alpha1-protease inhibitor concentration significantly increased 4 days after the provocative trial when compared with baseline values. Antigen-specific fecal IgE varied throughout the provocative trial, with peak levels following ingestion of test meals. We conclude that food hypersensitivities are present in SCWTs affected with the syndrome of PLE/PLN. Mild inflammatory bowel disease was already established in the 6 SCWTs of this report at the time of study, making it impossible to determine if food allergies were the cause or result of the enteric disease.

The clinical and pathological findings of idiopathic ductopenia were studied in a 30-year-old woman who initially manifested jaundice and pruritus. Serum biochemical tests of liver function indicated severe and progressive cholestasis. Viral hepatitis markers and circulating autoantibodies were absent. The patient had a normal cholangiogram and lacked evidence of inflammatory bowel disease. Histological examination of a liver specimen showed severe cholestasis and absence of interlobular bile ducts. Severe jaundice and intractable pruritus developed in the patient and served as the indications for liver transplantation 4 months after initial examination. Transplantation resulted in prompt and complete resolution of the jaundice and pruritus. Two types of idiopathic adulthood ductopenia associated with different prognoses are recognized. Patients with type 1 idiopathic adulthood ductopenia are asymptomatic or manifest symptoms of cholestatic liver disease. They tend to have less destruction of the intrahepatic bile ducts on liver biopsy specimens. Their clinical course ranges from spontaneous improvement to progression to biliary cirrhosis. In contrast, patients with type 2 idiopathic adulthood ductopenia generally manifest initial symptoms of decompensated biliary cirrhosis, have extensive destruction of the intrahepatic bile ducts on liver biopsy, and frequently require orthotopic liver transplantation.

The management of the patient with inflammatory bowel disease (IBD) is challenging for both the physician and the patient. IBD imposes both a physical and emotional burden on patients' lives. Palliative care is important for IBD patients because it focuses on improving quality of life. While palliative care does not change the natural history of the disease, it provides relief from pain and other distressing symptoms. This article focuses on various aspects of care for IBD patients including pain control, management of oral and skin ulcerations, stomal problems in IBD patients, control of nausea and vomiting, management of chronic diarrhea and pruritus ani, evaluation of anemia, treatment of steroid-related bone disease, and treatment of psychological problems associated with IBD. Each of these areas is reviewed using an evidence-based approach. Evidence in category A refers to evidence from clinical trials that are randomized and well controlled. Category B Evidence refers to evidence from cohort or case-controlled studies. Category C is evidence from case reports or flawed clinical trials. Evidence from category D is limited to the clinical experience of the authors. Evidence labelled as category E refers to situations where there is insufficient evidence available to form an opinion. Algorithms for management of pain and nausea in IBD patients are presented.

Primary sclerosing cholangitis (PSC) is a chronic cholestatic and progressive disease, of unknown etiology, characterized by inflammation and fibrosis of intra-hepatic and extra-hepatic biliary tree. Two thirds of the patients have, simultaneously, ulcerative colitis (UC); on the other hand, PSC is the most common chronic hepatic disease in patients with inflammatory bowel disease (IBD). Patients who have both diseases simultaneously are prone to develop colorectal carcinoma and cholangiocarcinoma. The disease predominantly affects young men, may be asymptomatic or presented as fluctuating jaundice, pruritus and increased levels of the cholestasis biochemical markers, or as secondary billiary cirrhosis. The diagnostic gold standard are the cholangiographic abnormalities, consisting of multifocal stenosis and dilatations, involving both the intrahepatic and the extrahepatic biliary tree. Liver biopsy is useful only for staging the disease and to confirm the diagnosis, in the atypical forms. Ursodeoxycholic acid is a promising drug, nowadays, mainly in the first stages of the disease, in spite of doubtful efficacy. Combination therapy, using ursodeoxicolic acid, methotrexate and alternating antibiotics monthly may be sucessfull in PSC before bile strictures occur. Liver transplantation is the only life-saving therapeutic alternative, able to improve significantly the survival and the life quality of the patients.

Normolipemic plane xanthomas are yellow-red-colored flat patches or plaques with barely palpable borders, under normolipemic conditions usually involving the eyelids, the lateral sides of the neck, the upper aspect of the trunk, or the flexural folds. Histologically the lesions are characterized by an infiltrate consisting of foamy macrophages in the papillary and middermis with a distinct perivascular localization. Plane xanthoma has been associated with monoclonal gammopathy, cryoglobulinemia, and myeloproliferative disorders. We present a patient in whom plane xanthoma developed on the upper aspect of the back, which was accompanied by severe itch in the affected area. These symptoms started 1 month after resection of an adenocarcinoma of the rectum that was complicated by recurrent abdominal abscesses and, currently, by ongoing inflammatory bowel disease. A hypothetic pathophysiologic scheme of events leading to xanthoma formation in this patient is presented.

When cholestatic liver disease is present, liver ultrasound should be performed to ascertain if cholestasis is extrahepatic or intrahepatic. If bile ducts appear dilated and the probability of interventional treatment is high, endoscopic retrograde cholagio-pancreatography (ERCP) or trans-hepatic cholangiography (THC) should be the next step. If the probability of interventional therapeutics is low, cholangio-MRI should be performed. Once bile duct dilation and space occupying lesions are excluded, a work up for intrahepatic cholestasis should be started. Some specific clinical situations may be helpful in the diagnostic strategy. If cholestasis occurs in the elderly, drug-induced cholestatic disease should be suspected, whereas if it occurs in young people with risk factors, cholestatic viral hepatitis is the most likely diagnosis. During the first trimester of pregnancy cholestasis may occur in hyperemesis gravidorum, and in the third trimester of gestation cholestasis of pregnancy should be suspected. A familial history of recurrent cholestasis points to benign recurrent intrahepatic cholestasis. The occurrence of intrahepatic cholestasis in a middle-aged woman is a frequent presentation of primary biliary cirrhosis, whereas primary sclerosing cholangitis should be suspected in young males with inflammatory bowel disease. The presence of vascular spider nevi, ascites, and a history of alcohol abuse should point to alcoholic hepatitis. Neonatal cholestasis syndromes include CMV, toxoplasma and rubinfections or metabolic defects such as cystic fibrosis, alpha1-antitrypsin deficiency, bile acid synthesis defects, or biliary atresia. The treatment of cholestasis should include a management of complications such as pruritus, osteopenia and correction of fat soluble vitamin deficiencies. When hepatocellular failure or portal hypertension-related complications occur, liver transplantation should be considered.

We analyzed 388 cases of primary sclerosing cholangitis (PSC) in Japan, according to a questionnaire sent to gastroenterologists. There was male predominance (59%), and interestingly there were two peaks in the age distribution as seen in the previous study. Jaundice and itching, major symptoms in PSC patients included in the diagnostic criteria, were observed only 28 and 16%, respectively. Alkaline phosphatase level was less than twofold of the upper limit of the normal range in 35%. In this regard, the diagnostic criteria in 2003 from Mayo Clinic, including cholestatic symptoms and two to three-fold increases in serum alkaline phosphatase, should be modified in Japan. Inflammatory bowel diseases were complicated in 37%, and autoimmune pancreatitis (AIP) in 7.2%. PSC cases with inflammatory bowel diseases were younger than the average, creating the first peak in the age distribution, and have similar characteristics compared to patients with PSC in foreign countries. By contrast, those with AIP, who were more than 50 years old, responded well to corticosteroid therapy. In addition, even after the exclusion of cases of sclerosing cholangitis complicated with AIP, the second peak in the age distribution was clearly evident. Therefore, we conclude that PSC patients without apparent involvement of the pancreas are present in the older patients and seem to be specific in Japan.
