The authors present a review of 21 cases with the diagnosis of type I amyloid neuropathy based on epidemiological data, clinical evolution and histopathological findings. They call attention to the possibility of cranial nerves involvement (hyposmia, diplopia, masseterian hypotrophy, peripheral facial paralysis, hypoacusis, dysphonia, laryngeal paralysis,
dysphagia
, and trapezium muscle hypotrophy), to the severeness of the digestive symptoms, to the precocity of the autonomic disorders, and to the rather high incidence (6 cases) of heart involvement. The electromyography showed anterior horn involvement in 3 cases. The electrocardiography showed repolarization disorders in 11 cases, left ventricular overload in 6 cases and atrioventricular block in 5 cases. The serum proteins electrophoresis showed frequent abnormalities, but no typical curve could be obtained. The barium-contrasted X-rays of the gastrointestinal tract showed no anatomical lesions, but functional abnormalities (hypo or hypermotility) were found in 14 examination. The Schilling test showed impairment of vitamin B12 absorption in 50% of the cases. However, with the concomitant administration of intrinsic factor (3 cases) there was improvement of it absorption. This proves that the gastric mucosa plays an important role in the disease malabsorption. The test with labeled-triolein showed slow absorption in 2 cases and
steatorrhea
in 3 (6 tests). For the confirmation of the amyloid deposits, the best histopathological procedure was nerve biopsy. In men, when the nerve biopsy was negative, testicular biopsy has shown to be a good option.

The nutritional status of a tumor patient can be negatively influenced by the local and systemic effects of the malignant tumor (tumor cachexia, anorexia, difficult oral food intake), by the effects of the various antitumoral therapy modalities (surgery, radiotherapy, chemotherapy), and by the complications associated with such modalities (anorexia, nausea, vomiting, mucositis, xerostomia, alterations of the smell and taste sensations, odynophagia,
dysphagia
, maldigestion, malabsorption, diarrhea,
steatorrhea
, conditioned aversions, radiogenic late effects), as well as by the psychological reactions of the patient to the real or feared existence of his tumor. The radiation-induced nutritional disorders depend on the tumor localization, the region irradiated, the dose and length of radiotherapy, the fractionation, the volume irradiated, and the combination with other therapeutic modalities ("combined modality therapy"). The acute radiation-induced reactions are usually of limited duration and for this reason tend to interfere with the nutritional status to a lesser extent than the permanent chronic consequences of irradiation. Weight loss and malnutrition tend to develop particularly in patients in whom segments of the gastrointestinal tract are subjected to irradiation. The incidence and severity of deficient nutrition depend not only on the region irradiated (head-neck region, thorax, abdomen, pelvis) but also, and most particularly, on the volume of the digestive tract irradiated. Chemotherapy and radiotherapy combined act very strongly on rapidly proliferating cell populations (skin, mucosa, epithelium of the gastrointestinal tract). In this context, actinomycin D and adriamycin act like real sensitizers, whereas the majority of the other drugs are likely to produce only an additive effect. The first named cytostatics give rise to the so-called recall phenomenon, i.e., the reactivation of latent radiation effects in response to the subsequent administration of the drug. Malnutrition impairs organ function and ultimately results in increased morbidity and mortality. For this reason it has proven mandatory and reasonable that the organism of all tumor patients suffering from malnutrition is provided with the missing essential nutrients (especially amino acids for protein synthesis). This tends to clearly improve the Karnofsky performance status, with a positive effect on response rates, toxicity, and survival rates in retrospective studies.(ABSTRACT TRUNCATED AT 400 WORDS)

We analyzed the clinical, radiographic, esophageal manometric, and pathological features of 10 patients referred with jejunal diverticulosis. Nine patients were over age 59 yr and had symptoms of intestinal pseudoobstruction of 5-43 yr duration. Seven had surgery for mechanical obstruction, although none was found. Eight had diarrhea,
steatorrhea
, and weight loss. Five had Raynaud's phenomenon and heartburn, and 2 had
dysphagia
. At radiography, 9 had jejunal diverticula with or without duodenal or ileal diverticula, or both. Two each had abnormal structure or motility of the esophagus or stomach. At manometry, 3 of 7 had a nonspecific motor abnormality, and 1 other had low amplitude peristaltic waves. Light microscopy of small intestinal tissue in 7 patients showed that 4 had fibrosis and decreased numbers of normal-appearing muscle cells, findings consistent with progressive systemic sclerosis. Two others had fibrosis associated with degenerated smooth muscle cells, findings consistent with a visceral myopathy. The seventh patient had neuronal and axonal degeneration and neuronal intranuclear inclusions, findings consistent with a visceral neuropathy. We conclude that (a) intestinal pseudoobstruction is a major clinical manifestation of jejunal diverticulosis, (b) jejunal diverticulosis is a heterogenous disorder associated with at least three abnormalities of the smooth muscle or myenteric plexus, (c) in contrast to intestinal pseudoobstruction without diverticulosis, the esophagus, stomach, and colon are less frequently involved in jejunal diverticulosis, and (d) some patients with jejunal diverticulosis probably have clinically inapparent progressive systemic sclerosis.

Thyroid disease is common, and its effects on the gastrointestinal system are protean, affecting most hollow organs. Hashimoto disease, the most common cause of hypothyroidism, may be associated with an esophageal motility disorder presenting as
dysphagia
or heartburn. Dyspepsia, nausea, or vomiting may be due to delayed gastric emptying. Abdominal discomfort, flatulence, and bloating occur in those with bacterial overgrowth and improve with antibiotics. Reduced acid production may be due to autoimmune gastritis or low gastrin levels. Constipation may result from diminished motility, leading to an ileus, megacolon, or rarely pseudoobstruction. Ascites in myxedema is characterized by a high protein concentration. Graves' disease accounts for 60% to 80% of thyrotoxicosis. Hyperthyroidism is accompanied by normal gastric emptying with low acid production, partly due to an autoimmune gastritis with hypergastrinemia. Transit time from mouth to cecum is accelerated, resulting in diarrhea.
Steatorrhea
is due to hyperphagia and stimulation of the adrenergic system. Diarrhea in medullary carcinoma of the thyroid (MCT) may be due to elevated calcitonin, prostaglandins, or 5-hydroxyindoleacetic acid. Ileal or colonic function may be abnormal. The esophagus may be compressed by benign processes, but more often by malignancies. MRI and CT scans are the best diagnostic modalities. The gastrointestinal manifestations of thyroid disease are generally due to reduced motility in hypothyroidism, increased motility in hyperthyroidism, autoimmune gastritis, or esophageal compression by a thyroid process. Symptoms usually resolve with treatment of the thyroid disease.

A 78 year old patient with type 2 diabetes mellitus was hospitalized because of weakness and poor nutritional status. For several years, he suffered from an unintended weight loss and chronic, pulpy diarrhea. On examination, we found a severe loss of muscle and fat tissue as well as
difficulty swallowing
. An adequate nutritional therapy with combined parenteral and enteral nutrition was implemented under regular monitoring of electrolytes and volume status, under which the state of health improved noticeably, while
steatorrhea
improved under substitution of pancreatic enzymes.

Dysphagia
is an uncommon symptom for celiac disease (CD). Typically, patients with CD present with abdominal pain, diarrhea,
steatorrhea
, weight loss, growth failure, anemia, or fatigue. We report a case of
dysphagia
in a pediatric patient with negative celiac serologies and positive histologic findings suspicious for CD. Our patient's
dysphagia
resolved after being placed on a gluten-free diet. Repeat interval endoscopy on a gluten-free diet to assess for resolution of histological changes confirmed the diagnosis of CD. In patients with
dysphagia
, CD should be considered in the differential diagnosis despite negative celiac serologies.
