A 6-year-old male Yorkshire Terrier had clinical signs including intermittent vomiting and diarrhea associated with abdominal distention. Contrast radiography disclosed dilatation and decreased motility of the small intestine, with dilution of barium. Hemograms, blood chemical profiles, and results of fecal examinations and urinalyses were normal. Obstruction was not found at exploratory laparotomy, but a dilated segment of mid-jejunum was biopsied. There was hypoplasia of the tunica muscularis of the jejunum, without fibrosis, inflammation, or myenteric plexus involvement. The diagnosis was idiopathic intestinal pseudoobstruction. Post-operative care consisted solely of feeding bland foods. Three months after surgery there was progressive deterioration and emaciation due to chronic intestinal malabsorption.

Tropical sprue is a diagnosis about which we have to think when we are confronted to a patient back from overseas. We examined a young man back from Central African Republic where he got diarrhoea which keeps going on in France, with alteration of his general condition and stigmata of malabsorption. Taking advantage of such observation, the authors report on the present knowledge about that disease peculiar to tropical zone. Biological elements of malabsorption are associated to partial emaciation of villi of small intestine. As a matter of fact, diagnosis is made by elimination. Its pathogenesis remains unknown and is linked to some troubles of intestinal microbism of which exact causes has not been yet put into evidence. An easy treatment by tetracycline and folic acid is a true diagnosis test, as general condition is set up again, as well as villi intestinalis.

Eleven adult Basenji dogs with immunoproliferative small intestinal disease (IPSID) were studied. Two items of history related to the digestive tract were characteristic: (i) chronic intractable diarrhea in most dogs, and (ii) progressive emaciation. Anorexia was intermittent in only a few dogs. In addition, skin lesions of various degrees of severity were observed, including alopecia of pinnae and ventrum, hyperpigmentation and hyperkeratosis of pinnae, and necrosis and ulcerations of margins of pinnae. The cause of the skin lesions was not determined; however, hypothyroidism did not appear to contribute to the skin changes. Standard hematologic and serum chemical values were not consistently abnormal. However, a poorly regenerative anemia, mild neutrophilia, and increased aspartate aminotransferase and alanine aminotransferase activities were generally observed in severely affected dogs. The Pelger-Huet anomaly was identified in dog 3. Maldigestion and malabsorption as determined by the N-benzoyl-L-tyrosyl-p-aminobenzoic acid and d-xylose test was documented to varying degrees in dogs with IPSID. Maldigestion was correlated with functional pancreatic exocrine insufficiency. Severe malabsorption was documented in only 3 dogs. Serum gastrin values were evaluated in these dogs because of a prior observation of parietal cell hyperplasia and gastric ulceration. Hypergastrinemia was documented in 3 dogs. Additional studies will be necessary to determine whether an acid hypersecretory state contributes to the pathogenesis of IPSID in Basenjis.

A 4-year-old stallion was examined because of a 2-month history of inappetance and weight loss. Diarrhoea had also developed a month before presentation. Abnormal clinical findings were emaciation, diarrhoea, ventral oedema, palpable mesenteric lymph node enlargement and a large mass in the left cranial portion of the abdomen. Significant laboratory findings were anaemia (packed cell volume 0.21 litres/litre), hypoalbuminaemia (16 g/litre) and xylose malabsorption. The horse was euthanased and at necropsy a 10.5 kg pendunculated mass composed of granulation tissue was found within and attached to the stomach. There was villous atrophy diffusely throughout the small intestine. The inciting cause of the gastric mass was not determined.

An epidemiological investigation into an "illthrift" problem occurring on a dairy farm adjacent to an alloy-processing unit, established that the probable cause of the problem was chronic vanadium poisoning. The disease manifested initially in animals 4-18 months old which showed emaciation, chronic diarrhoea and, in some cases, rhinitis, conjunctivitis and recumbency followed by death. Post-mortem (n = 17) and clinical-pathology findings (n = 60) indicated that malabsorption and immunosuppression were the basis of the pathogenesis in affected animals. Eight months after the commencement of the investigation, adult cows began showing evidence of emaciation, reduced milk production and an apparent increase in the number of abortions, stillbirths and dystocias. Over a 2-year period, 134 surface-soil samples, 134 subsoil samples and 134 grass samples from the farm were analysed for various fractions of vanadium. Thirty-four of each of these samples were collected at different time intervals (autumn 1990, summer 1991 and winter 1991) and at varying distances and directions from the processing unit, in order to gauge the magnitude of the problem, and the distribution pattern of vanadium, and to identify possible seasonal trends. The remaining 100 of each of these samples were taken at 100-m intervals over an area of approximately 1,140,000 m2 directly adjacent to the processing unit so that concentration isolines for vanadium could be drawn and the source more conclusively identified. The levels of vanadium were found to be highest closest to the mine, and surface-soil levels were consistently higher than subsoil levels, suggesting aerial pollution, which was confirmed by air sampling.(ABSTRACT TRUNCATED AT 250 WORDS)

We report the case of a twenty-three month old, normally eating child, affected by organic macies and severe dystrophy. After the negative response of blood and laboratory examinations let us exclude a malabsorption syndrome, only the performance of neuro-radiologic exams showed evidence of a subthalamic tumor as the cause of a "Diencephalic syndrome". Diencephalic syndrome or Russel's syndrome is a diencephalic tumor induced disease, which sets in the first three years of life. The disease clinical markers are a severe emaciation with appetite preservation and absence or very scarce evidence of any telltale neurological sign. the tumoral histo-pathology most frequently shows a low grade of malignancy astrocytoma, whose eradication is very often difficult because of the particular anatomic site. Choice treatment includes an excisional biopsy associated to chemotherapy and to radiotherapy.

We report herein the case of a 59-year-old man in whom blind pouch syndrome was successfully treated by laparoscopic surgery. The patient had undergone distal gastrectomy and Roux-en Y gastrojejunostomy for a peptic ulcer 35 years previously, and had been suffering from watery diarrhea, anemia, weight loss, and pain in the left upper quadrant of his abdomen for several years. Long-term insufficient oral intake and the malabsorption of nutrients had resulted in severe emaciation. Gastrointestinal contrast study revealed a large blind pouch, 30 x 23cm in diameter, draining into the gastrojejunostomy. Laparoscopic resection of the blind pouch was performed. Despite the presence of dense intraabdominal adhesions, we identified the blind pouch with the help of tattoo marks that had been made at the neck of the pouch preoperatively. After thoroughly dissecting the adhesions around the pouch, we resected the pouch at the neck. The patient had an uneventful postoperative course. This case report demonstrates that large blind pouches such as this may be effectively treated using laparoscopic surgery.

Diencephalic syndrome (DS) is a complex of signs and symptoms related to hypothalamic dysfunction. Its main features are emaciation despite normal energy intake and an alert appearance. This syndrome has been described in association with space-occupying lesions of the hypothalamic-optic chiasm region, mainly low-grade glioma, and less often with tumors in the proximity of the IV ventricle. Two patients with DS are reported. The first patient was an 8-month old boy with classical features of DS. Extensive investigation of malabsorption revealed no abnormalities and the first neurologic sign was a rotatory nystagmus. Magnetic resonance imaging (MRI) showed evidence of a hypothalamic tumor, which was identified after surgical resection as a pilocytic astrocytoma. The second patient was an adolescent boy who presented a 20-kg weight loss over a 6-month period and psychological disturbances. Gastrointestinal disease was ruled out as a cause of malnutrition. Because of a polydipsia-polyuria syndrome, manifest while the patient was hospitalized with a suspected diagnosis of anorexia nervosa, MRI of the brain was performed. Multiple intracranial lesions were revealed, mainly in the hypothalamus, and were identified as a disseminated disgerminoma. No neurologic signs or symptoms were present. The patients died 2 years and 1 year after diagnosis, respectively. Although DS is rare, it should be considered in severe failure to thrive or emaciation despite adequate food intake and normal absorptive function of the small bowel.

We report the case of a two years old, normally eating child, affected by organic macies and severe dystrophy. After the negative response of blood and laboratory examinations let us exclude a malabsorption syndrome, only the performance of neuro-radiologic exams showed evidence of a subthalamic tumor as the cause of a "Diencephalic syndrome". Diencephalic syndrome or Russell's syndrome is a diencephalic tumor induced disease, which sets in the first time of life. The disease clinical markers are a severe emaciation with appetite preservation and absence or very scarce evidence of any telltale neurological sign. The tumoral histo-pathology most frequently shows a low grade of malignancy astrocytoma, whose eradication is very often difficult because of particular anatomic site. Treatment of choice includes an excisional biopsy with chemotherapy and radiotherapy. We report a clinical case of long-term survival and review of the literature.

The omega loop gastric bypass (OLGB) has become a very commonly performed bariatric procedure because of the advantages it carries over the Roux en Y gastric bypass (RYGBP). However, mini gastric bypass is a misnomer, as this procedure is more malabsorptive than the RYGBP. Recently, it is called single or one anastomosis gastric bypass. The omega loop procedure is associated with a risk of afferent loop syndrome, a known complication of the Billroth II (Finsterer) operation. This rare complication of the OLGB can be debilitating, serious, and deadly. Afferent loop syndrome should be suspected in case of malabsorption syndrome with chronic diarrhea, steatorrhea, iron-deficiency anemia, edema, emaciation, and osteomalacia and also in case of simple biological anomalies such as macrocytosis or megaloblastic anemia. The diagnosis can be confirmed by measuring bacterial overgrowth, although this requires a jejunal aspirate performed during endoscopy with jejunal intubation. A microbial population of more than 106 organisms per milliliter of aspirate is pathological. Afferent loop syndrome is encountered less frequently now that the number of gastrectomies has dropped. Yet, with the omega loop bypass procedure becoming more common, surgeons must again be made aware of this potential complication.
