  • Liver Disease, and Nutrition-Related Challenges
    Chapter 9 Clinical Care of Fanconi Anemia Gastrointestinal Issues Introduction Fanconi anemia (FA) and medications used to treat the disease can cause gastrointestinal disorders, liver disease, and nutrition-related challenges. Without proper treatment, these complications can interfere with daily living and create hurdles for healthy growth and development. Concerns related to the gastrointestinal tract that affect patients with FA most commonly include: • Anatomic abnormalities of the gastrointestinal tract • Gastrointestinal symptoms, including poor food intake, nausea, abdominal pain, and/or diarrhea • Poor weight gain or malnutrition, often resulting from reduced food intake or difficulty absorbing nutrients from food • Overweight or obesity • Cancers of the gastrointestinal tract • Liver disease • Gastrointestinal-related complications of hematopoietic cell transplantation (HCT) 147 The gastrointestinal clinical care team should include a gastroenterologist or pediatric gastroenterologist and, when needed, a dietician. This team should work in close collaboration with other FA specialists to provide comprehensive care. Gastrointestinal Tract Anatomic Abnormalities Approximately 7% of patients with FA are born with anatomic abnormalities in the gastro- intestinal tract [1]. The most common abnormalities include esophageal atresia (EA), EA with tracheoesophageal fistula (TEF), duodenal atresia, and other anorectal malformations. These malformations may include a blockage of the anus, a failure of the rectum to connect to the anus, or an abnormal passage between the rectum and another part of the body, such as the urinary tract or reproductive system. Most anomalies are diagnosed and treated in early infancy, often before the diagnosis of FA. Gastrointestinal tract abnormalities may occur in isolation or appear with other birth defects, including the VACTERL-H spectrum of disorders (described in Chapter 2).

  • DANOCRINE Brand of DANAZOL CAPSULES, USP
    ® DANOCRINE Brand of DANAZOL CAPSULES, USP DESCRIPTION DANOCRINE, brand of danazol, is a synthetic steroid derived from ethisterone. It is a white to pale yellow crystalline powder, practically insoluble or insoluble in water, and sparingly soluble in alcohol. Chemically, danazol is 17α-Pregna-2,4-dien-20-yno [2,3-d]­ isoxazol-17-ol. The molecular formula is C22H27NO2. It has a molecular weight of 337.46 and the following structural formula: Danocrine capsules for oral administration contain 50 mg, 100 mg or 200 mg danazol. Inactive Ingredients: Corn Starch, Lactose, Magnesium Stearate, Talc. Capsules 50 mg, 100 mg and 200 mg contain D&C Yellow #10, FD&C Red #40, Gelatin, Silicon Dioxide, Sodium Lauryl Sulfate, Titanium Dioxide. The 50 mg and 200 mg capsules also contain D&C Red #28. CLINICAL PHARMACOLOGY DANOCRINE suppresses the pituitary-ovarian axis. This suppression is probably a combination of depressed hypothalamic-pituitary response to lowered estrogen production, the alteration of sex steroid metabolism, and interaction of danazol with sex hormone receptors. The only other demonstrable hormonal effect is weak androgenic activity. DANOCRINE depresses the output of both follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Recent evidence suggests a direct inhibitory effect at gonadal sites and a binding of DANOCRINE to receptors of gonadal steroids at target organs. In addition, DANOCRINE has been shown to significantly decrease IgG, IgM and IgA levels, as well as phospholipid and IgG isotope autoantibodies in patients with endometriosis and associated elevations of autoantibodies, suggesting this could be another mechanism by which it facilitates regression of the disease.

The imageology of hepatic peliosis resembles hepatocellular carcinoma, hepatic metastases and hemangioma. We report a case of hepatic peliosis imitating metastases on CT. The patient was 26-year-old man who previously had a splenectomy and retroperitoneal paraganglioma surgically removed. Peliosis must be considered a potential differential diagnosis of hypodense foci of the liver seen on CT. Keywords: Peliosis, CT scan, FNAC The liver, pancreas, both kidneys and suprarenal glands appeared normal. The retroperitoneal lesion was surgically removed in total. Background With suspecting splenic lesions as metastases, total splenectomy was Peliosis is characterized by blood-filled thin-walled vessels/cavities also done. Histologically, the retroperitoneal lesion appeared benign with a cystic appearance often found throughout the parenchyma of and confirmed as paraganglioma. After splenectomy, histology the organ involved [1]. “Peliosis” is a term derived from the Greek confirmed that the splenic lesions were benign vascular lesion with pelios, which means “dusky” or “purple,” referring to the color of atypia composed of endothelial lined blood vessels. the liver parenchyma with peliosis. The lesion may be found in liver, and may be seen in the spleen, lymph nodes, and other organs Postoperatively, the patient was asymptomatic for 3 years.

  • Board Questions
    Question 1: A 14-year-old youth has had intermittent periumbilical and lower abdominal pain, some bloating, and increased flatus for 2 years. He denies a relationship of the pain to food or drink, and a milk-free diet did not relieve his symptoms. He has had no fevers, diarrhea, constipation, bleeding, or other systemic problems and his growth is normal. He eats a regular diet, including diet soft drinks and sugar-free gum. His family is intact and he denies undue stress in his school or social life. He also denies alcohol, drug use, or smoking. Physical examination is normal, including heme occult negative rectal examination. Screening laboratory tests including complete blood count, ESR, liver enzymes and amylase, and urinalysis are normal. Which one of the following would be the most likely etiology of the abdominal complaints in this teenager? A. lactose intolerance B. excessive sorbitol intake C. irritable bowel syndrome D. teenage stresses E. acid-peptic disease Suggested answer: B or C. Sorbitol is a FODMAP (fermentable oligo-, di-, and monosaccharides and polyols), metabolized by colonic bacteria to produce short chain fatty acids and gas. Sorbitol is commonly found in diet soft drinks and sugar-free gum. When taken in excess, sorbitol produces enough gas to produce abdominal pain and bloating as in this patient. Sorbitol can also cause a persistent, osmotic diarrhea.
