A 24-year-old woman came to the emergency room with a history of diffuse abdominal pain in the form of colic, nausea, vomiting and intestinal constipation. Clinical and ultrasound findings suggested intestinal obstruction due to foreign body. She had been submitted to a cesarean section 4 months previously at another hospital. At laparotomy, a ileum loop was found to be distended by an inside large and hardened mass with another intestinal loops and omentum density adherent. An ileotomy was performed on the compromised segment with terminating anastomosis. When opened surgical specimen it was observed an intraluminal surgical sponge that had completely migrated into the interior of the ileum and stopped next to ileumcecal valve. No fistulas or open intestinal wall were observed.

We present the clinical case of a patient with vascular compression of the duodenum or superior mesenteric artery compression syndrome.A female, 42 years old, with history of two months' evolution characterized by postprandial epigastric colic, without irradiation, accompanied by nausea and intractable vomiting, weight loss and gastric shaking. A double contrast gastric duodenum x-ray showed the duodenal frame with exaggerated dilatation and stenosis close to the Treitz angle, through which the contrast media barely flowed. The endoscopy revealed duodenal obstruction, gastric retention and erosive esophagitis. The computerized tomography identified a significant dilatation of the duodenal arc, with stenosis on the aorto-mesenteric junction. We performed an exploratory laparotomy, making a latero-lateral duodenojejunal trans-mesocolic anastomosis. Satisfactory evolution and discharge without complications.

The resistance of Eucalyptus to browsing mammals has been related to the level and type of formylated phloroglucinol compounds (FPCs) present in the leaf. The antifeedant activity of FPCs appears to depend on their aldehyde groups, but little else is known of their mode of action. We have sought to elucidate this further by examining the biological reactivity and disposition of jensenone, a model FPC. Neither jensenone nor any metabolites were detected in urine or feces of marsupial brushtail or ringtail possums that had ingested up to 725 mg x kg(-0.75). When jensenone was incubated in rat gastrointestinal segments in vitro, it rapidly disappeared. Jensenone also reacted rapidly with glutathione, cysteine, glycine, ethanolamine, and trypsin, and more slowly with acetylcysteine and albumin. Sideroxylonal, a more complex FPC, exhibited the same reactivity. Torquatone, a related compound that lacks both aldehyde groups and antifeedant activity, was unreactive. Mass spectroscopic analysis indicated that the adducts were Schiff bases formed between the aldehyde groups of FPCs and amine groups of the conjugating molecules. Successive adducts were formed with the two aldehyde groups of jensenone, and the four groups of sideroxylonal. The jensenone bis-glutathione adduct appeared to cyclize to the disulfide form. These findings suggest that the antifeedant effects of FPCs are due to their facile binding to amine groups on critical molecules in the gastrointestinal tract, leading to a loss of metabolic function. The consequent toxic reaction, probably involving chemical mediators such as 5-hydroxytryptamine (5HT), may cause colic, nausea, and a general malaise, resulting in anorexia.

Aneurysms of the superior mesenteric artery branches are rarely reported, even among them colic artery aneurysms are seldom. We report a case of 78-year-old male with ruptured dissecting aneurysm of middle colic artery. The patient complained abdominal pain and nausea during hospital stay for renal stone. The patient suddenly developed severe abdominal pain, leading to shock. He underwent emergency surgery under a preoperative diagnosis of intraperitoneal hemorrhage. At exploratory laparotomy, a large hematoma involving the mesentery root of the transverse colon was associated with a ruptured aneurysm measuring 15 x 10 mm in size, which was located to the mid-portion of middle colic artery. Right-hemicolectomy was carried out because of ischemic changes in the ascending colon. Histological examination demonstrated a ruptured dissecting aneurysm of the middle colic artery approximately 5 cm in length, associated with destruction of the tunica interna and media. The aneurysm was thought to result from idiopathic segmental arterial mediolysis, because no definitive evidence of atherosclerosis or arteritis was observed.

A total of 82 out-patients were examined for Giardia copro-antigens and 12 neonate stool samples as control. ELISA had a sensitivity of 100% and specificity of 91.67%. ELISA (O.D.) had neither significant correlation to Giardia cyst count, to stool consistency or presence of blood, mucus or fat in stool, nor to age but positive correlation to the severity of diarrhoea, colic, nausea, anorexia, weight loss, distension and fatigue. Giardia cyst count was higher in cases with loose stool, while ELISA (O.D.) correlated positively with symptoms except constipation and vomiting. The different in clinical outcome of giardiasis can be attributed, partially to strain differences and host resistance.

Although the incidence of occupational and adult lead poisoning has declined, the problem still exists. We encountered three patients with lead poisoning in Iran, all of whom associated with presented with diffuse abdominal pain, which was at times colicky in nature, anemia, constipation, nausea, vomiting, and slightly abnormal liver biochemistries. A history of opium ingestion was present in each of these patients. None of the patients reported known occupational exposure to toxins. Diagnoses of lead poisoning were confirmed through the detection of elevated blood lead levels. The cause of lead poisoning was attributed to the ingestion of contaminated opium. Opium adulterated with lead had not been previously recognized as a source of lead poisoning in Iran. It is, therefore, pointed out that lead poisoning should be considered as a differential diagnosis for acute abdominal colic of unclear cause in patients with opium addiction.

Adverse reactions to foods are frequent in everyday life. They are divided into toxic and immunologic food reactions. The awareness of toxic food reactions among adverse reactions to food is essential for correct diagnosis. Enzymatic food intolerance, adverse reactions to food or food additives, pharmacologic food intolerance, psychosomatic factors, food allergy with classic symptoms (anaphylaxis, urticaria-angioedema), atopic dermatitis, contact dermatitis (protein), upper and lower respiratory symptoms like rhinitis or asthma, and gastrointestinal disorders (oral allergy syndrome, colic, nausea, vomiting, diarrhea, abdominal pain) are discussed. Target organs throughout the body-ear, eye, pharynx, skin, lung, joints, and muscles-can be involved. The gold standard in diagnosis is a double-blind, placebo-controlled food challenge test. The diagnostic tools available for most food-related disorders are the skin-prick test and radioallergosorbent test. The treatment of food-induced urticaria consists of elimination of the offending food or substance from the diet, use of antihistamines, and immunotherapy.

Chagas' disease (American trypanosomiasis) is an endemic parasitic disease in some areas of Latin America. About 16-18 million persons are infected with the aetiological agent of the disease, Trypanosoma cruzi, and more than 100 million are living at risk of infection. There are different modes of infection: (1) via blood sucking vector insects infected with T. cruzi, accounting for 80-90% of transmission of the disease; (2) via blood transfusion or congenital transmission, accounting for 0.5-8% of transmission; (3) other less common forms of infection, eg, from infected food or drinks or via infected organs used in transplants. The acute phase of the disease can last from weeks to months and typically is asymptomatic or associated with fever and other mild nonspecific manifestations. However, life-threatening myocarditis or meningoencephalitis can occur during the acute phase. The death rate for persons in this phase is about 10%. Approximately 10-50% of the survivors develop chronic Chagas' disease, which is characterized by potentially lethal cardiopathy and megacolon or megaoesophagus. There are two drugs available for the aetiological treatment of Chagas' disease: nifurtimox (Nfx) and benznidazole (Bz). Nfx is a nitrofurane and Bz is a nitroimidazole compound. The use of these drugs to treat the acute phase of the disease is widely accepted. However, their use in the treatment of the chronic phase is controversial. The undesirable side effects of both drugs are a major drawback in their use, frequently forcing the physician to stop treatment. The most frequent adverse effects observed in the use of Nfx are: anorexia, loss of weight, psychic alterations, excitability, sleepiness, digestive manifestations such as nausea or vomiting, and occasionally intestinal colic and diarrhoea. In the case of Bz, skin manifestations are the most notorious (e.g., hypersensitivity, dermatitis with cutaneous eruptions, generalized oedema, fever, lymphoadenopathy, articular and muscular pain), with depression of bone marrow, thrombocytopenic purpura and agranulocytosis being the more severe manifestations. Experimental toxicity studies with Nfx evidenced neurotoxicity, testicular damage, ovarian toxicity, and deleterious effects in adrenal, colon, oesophageal and mammary tissue. In the case of Bz, deleterious effects were observed in adrenals, colon and oesophagus. Bz also inhibits the metabolism of several xenobiotics biotransformed by the cytochrome P450 system and its reactive metabolites react with fetal components in vivo. Both drugs exhibited significant mutagenic effects and were shown to be tumorigenic or carcinogenic in some studies. The toxic side effects of both nitroheterocyclic derivatives require enzymatic reduction of their nitro group. Those processes are fundamentally mediated by cytochrome P450 reductase and cytochrome P450. Other enzymes such as xanthine oxidoreductase or aldehyde oxidase may also be involved.

Severe abdominal colic because of lead poisoning is an uncommon condition in adults. The diagnosis of lead toxicity is often delayed and abdominal pain is mistaken for acute abdomen. We describe three blood brothers who were involved in pottery glazing and suffered from repeated episodes of severe abdominal pain, nausea, vomiting, constipation and anemia due to lead toxicity. The patients had a history of several hospitalizations and one or two unnecessary laparotomies. One patient had wrists drop and weakness of the fingers extensors. All three patients had microcytic microchromic anemia with basophilic stippling of the erythrocytes, lead lines in X-ray of the knee joint and high blood lead levels. A diagnosis of lead poisoning was made and a course of chelating treatment started. Motor neuropathy, anemia and all gastrointestinal symptoms disappeared. Our report highlights the importance of taking a detailed occupational history and considering lead poisoning in the differential diagnosis of acute abdominal colic of unclear cause.

Superior mesenteric artery (SMA) syndrome is a rare acquired disorder in which acute angulation of SMA causes compression of the third part of the duodenum between the SMA and the aorta, leading to obstruction. Loss of fatty tissue as a result of a variety of debilitating conditions is believed to be the etiologic factor causing the acute angulation. We report a case of 30 years old lady who presented with postprandial abdominal pain at the epigastric region, colic type without radiation accompanied by nausea, postprandial vomiting and weight loss. Esophageal gastric series revealed an abrupt interruption in the contrast medium flow at the level of the junction of third portion (midpart) of the duodenum in barium studies. Adiverticula is noted just proximal to the site of obstruction. High resolution ultrasound and color Doppler sonography showed narrowing of the aortomesenteric angle to 220. Duodenojejunostomy was performed in the patient. Unfortunately the patient later was admitted in the hospital for refractory gastroparesis associated with superior mesenteric artery syndrome. Although open and laparoscopic duodenojejunostomy have been described as the best surgical treatment options for Wilkie's syndrome, but further attention is needed to the management of patients with refractory symptoms of gastroparesis after corrective surgery.
