In this review I have described the pathophysiology of allergic disorders of the gastrointestinal tract. Situations where the intestine cannot be a complete barrier to foreign allergens and antigens were discussed and etiological factors of gastrointestinal allergy were detailed. Clinical features of gastrointestinal allergy include diarrhea, vomiting, abdominal pain and colic, intestinal hemorrhage and malabsorption as well as symptoms and signs outside the gastrointestinal tract such as chronic rhinitis and asthma in the respiratory system, urticaria, angioedema and eczema as dermatological signs, headache, insomnia, hyperkinesis as central nervous system manifestations, failure to thrive and anaphylaxis as constitutional reactions. Milk allergy was discussed as an example of food allergy. Immunology of the gastrointestinal tract was presented, with examples of four types of hypersensitivity reactions, and gastrointestinal disturbances of immunodeficiency disorders and syndromes were named. Lastly, the autoimmune mechanism and the gut were described, with particular discussion of ulcerative colitis as an example of an autoimmune disease.

Primary biliary cirrhosis (PBC) is likely an autoimmune disease that destroys the interlobular bile ducts. Although the term PBC implies cirrhosis, this is not always present. The condition may be entirely silent clinically, save for the hallmark mitochondrial antibodies in serum. The clinical spectrum of PBC ranges from asymptomatic anicteric cholestasis with or without extrahepatic manifestations to severe cholestasis with decompensated cirrhosis. It is uncertain whether or not the course of this disease is universally fatal. Currently, no specific features have been identified which predict progression from asymptomatic to symptomatic disease, although once hyperbilirubinemia is present, a rising level indicates a poor prognosis. The liver-specific complications include pruritus, abdominal pain, xantholasma, and portal hypertension. The latter is often an early feature, as the portal hypertension is presinusoidal in nature and, when present, does not always reflect the presence of cirrhosis. There are many extrahepatic features of PBC, the most common being metabolic, chiefly hypothyroidism and metabolic bone disease. Other common associations are rheumatologic, renal, pulmonary, neuromuscular, and dermatologic. The non-specific yet distressing symptom of fatigue affects up to two-thirds of PBC subjects, but its etiology remains obscure.

We present a rare case of acute pancreatitis associated with temporal lobectomy due to intractable seizure in a 23-year-old man. The patient underwent elective right temporal lobectomy and hippocampectomy. Severe upper abdominal pain occurred just 10 hours after surgery. The diagnosis of acute pancreatitis was based on the elevation of serum amylase and lipase levels, and the findings of abdominal computerized tomography. Other possible causative factors of acute pancreatitis including alcohol, biliary tract stone, hypertriglyceridemia, hypercalcemia, hyperparathyroidism, biliary dysmotility and autoimmune disease were excluded by a series of examinations. The possibility of drug-induced pancreatitis was very low in this patient. The patient was discharged after supportive treatment. No recurrence of seizure or abdominal pain was noted in the three months after discharge. Acute abdominal pain after brain surgery deserves clinical evaluation for acute pancreatitis.

A-16-year-old male adolescent with a 4-year history of protean clinical manifestations such as fever, abdominal pain, back pain, erythema nodosum and uveitis developed complete occlusion of left renal artery. Although he had been suspicious of having an autoimmune disease and treated with prednisolone, a definite diagnosis was not made. Finally, an angiography disclosed stenosis of abdominal aorta just beneath the origin of the renal arteries as well as complete occlusion of left renal artery. It has been reported that pediatric-onset Takayasu's arteritis sometimes shows protean clinical manifestations as in ours. Takayasu's arteritis should be considered as one of the underlaying disease, when a child develops protean manifestations suggesting an autoimmune disease.

The prevalence of thyroid disease is increased in Down's syndrome. Compared with adults, thyroid dysfunction in children with Down's syndrome is less frequently reported. Insulin dependent diabetes mellitus is also uncommon in Down's syndrome children. Coexistent insulin dependent diabetes mellitus and hyperthyroidism in Down's syndrome was only reported once previously in literature. We report an 8-year-old girl with Down's syndrome that had polyuria, polydipsia, abdominal pain and urinary incontinence one and half a month prior to admission. Physical examination revealed typical face of Mongolism and tachycardia. Thyroid glands were not palpable. Laboratory data revealed diabetic ketoacidosis with plasma glucose: 860 mg/dl. She had thyroid hyperfunction with TSH: < 0.1 microU/ml, T3: 219.7 ng/dl, T4: 15 micrograms/dl. Thyroid autoimmune antibodies were also increased. There was markedly increased radiotracer uptake in the bilateral thyroid glands in Tc-99 thyroid scan. We suggest that Down's syndrome children with insulin dependent diabetes mellitus should be evaluated carefully for thyroid function and autoimmune disease.

Typical urticarial lesions are transient cutaneous swellings of sudden onset, often itchy, persisting for less than 24 hours and resolving to leave normal appearing skin. Angioedema lesions are similar subcutaneous lesions. Atypical urticarias persist for longer than 24 hours, may be painful and bruised in appearance and accompanied with severe systemic symptoms. Conditions where prolonged weals are present include delayed pressure urticaria and urticarial vasculitis. These conditions do not respond well to antihistamine therapy. In delayed pressure urticaria, weals appear after a delay of hours at sites of sustained pressure on the skin and occur in association with ordinary chronic 'idiopathic' urticaria. Weals of urticarial vasculitis show histological features of venulitis, and can be accompanied by arthralgia and abdominal pain. Rarely, the condition is due to infective or autoimmune disease. Urticarial diseases, sometimes with features of urticarial vasculitis, and with associated systemic features include Schnitzler's Syndrome, Still's disease and Muckle-Wells syndrome. The latter syndrome is linked with chromosome 1q44, as is autosomal dominant cold urticaria, an unusual physical urticaria. Persistent cholinergic erythema, a variant of cholinergic urticaria, has been mistaken for a drug eruption or cutaneous mastocytosis. Rarely, food and exercise induced urticaria and anaphylaxis occur when exercise follows a specific food or any meal within a few hours. The early stages of inflammatory disease may be mistaken for urticaria and angioedema, but lesions usually persist for longer than 48 hours and are accompanied by epidermal changes.

Lymphoepithelial cyst (LEC) of the pancreas is a rare lesion of undetermined pathogenesis that had been documented almost exclusively in males. The literature on this entity is limited to reports of single or small numbers of cases. Here is presented a clinicopathologic analysis of 12 patients with LEC, 4 of whom were female. The mean age of the patients was 56 years. Four patients presented with abdominal pain and nausea, but in two patients, the cysts were detected incidentally. Only one patient had a history of chronic pancreatitis, and another had a family member with pancreatic cancer. In one patient, a clinical diagnosis of pseudocyst was rendered, and the remaining patients were clinically thought to have cystic neoplasms. None of the patients had any identifiable immunosuppression, HIV positivity, autoimmune disorder (such as Sjogren syndrome) or lymphoma. Seven cysts were located in the head of the pancreas, and 5 were in the tail. The mean size was 4.8 cm (range, 1.2-17 cm). Five LECs were multilocular, three were unilocular; in others, the number of loculi was not recorded. All were "macrocystic" lesions. Two patients had two separate lesions, both in the tail of the pancreas. Histologically, all cases were characterized by cysts, some containing keratin, and lined by mature stratified squamous epithelium surrounded by dense lymphoid tissue, often with prominent follicles. In some areas, the lining epithelium had more cuboidal, flattened, or transitional appearance. Mucinous goblet-like cells were seen in one case. Acute inflammation was not seen. Four cases contained solid lymphoepithelial islands, a feature not previously described in LECs. No squamous metaplasia was identified in the uninvolved pancreatic tissue and no epithelial elements were identified in peripancreatic lymph nodes. In summary, LEC of the pancreas is a rare but distinctive lesion that may be seen in the tail of the organ where most cystic pancreatic neoplasms are encountered. In contrast to the impression from the literature, LECs may also develop in females and, therefore, should be considered in the clinical differential diagnosis of mucinous cystic neoplasms that affect a similar age group. LECs are not associated with the clinical syndromes that are seen with their analogues in the salivary glands.

We report the case of a 71-year-old man with mixed glomerular lesions, membranous and necrotizing changes. The patient had abdominal pain and purpurat on the extremities and trunk, followed by melena, and after admission to hospital, proteinuria and occult blood were noted. Laboratory findings were negative for autoimmune disease and viral hepatitis. Renal biopsy showed segmental necrotizing changes and mesangial proliferation with spike formation. Immunofluorescence revealed a granular deposition of IgA predominantly in the mesangial area in contrast to the granular IgG deposition along the glomerular capillary loops. Moreover, electron-microscopically, mesangial as well as subepithelial electron-dense deposits were observed. These data suggest that the patient had 2 distinct types of glomerulonephritis simultaneously: idiopathic membranous nephropathy and purpura nephritis.

A patient with ulcerative colitis (UC) who developed idiopathic myelofibrosis (IM) is reported. The initial diagnosis of UC was established by colonoscopy and large bowel biopsy, performed after a one-month history of abdominal pain and bloody diarrhea. The patient showed a favorable response to prednisone and mesalamine treatment and six months later he developed a new episode of UC, which was successfully controlled with treatment. However, two years later splenomegaly and anemia were observed, with aniso-poikilocytosis, tear-drop cells, immature myeloid precursors in the peripheral blood, and increased serum LDH, arising the suspicion of IM, a diagnosis that was confirmed by bone marrow biopsy. The present case represents a new association of IM with an autoimmune disease and gives support to the hypothesis of a possible immune basis of some IM cases.

A woman with scleroderma and classic polyarteritis nodosa (PAN) who developed idiopathic myelofibrosis (IM) is reported. The patient presented with a one-year history of weakness, polyarthritis, Raynaud phenomenon, dry cough, and epigastralgia. The diagnosis of scleroderma with visceral involvement was made and treatment with prednisone subsequently started, with good clinical response. Six years later, fever, weight loss, livedo reticularis, and dysesthesias developed. Electromyographic studies were consistent with sensory neuropathy and a sural nerve biopsy yielded the diagnosis of PAN. The patient received cyclophosphamide plus prednisone with a favorable response, but 11 years later she was admitted because of weakness, constitutional symptoms, and abdominal pain due to spleen infarcts. Marked anemia, with aniso-poikilocytosis, tear-drop cells, immature myeloid precursors in the peripheral blood, and an increased serum LDH, was observed and the diagnosis of IM established by bone marrow biopsy. This case represents a new association between IM and an autoimmune disease and supports the hypothesis of an immune basis of IM in some patients.
