[Autoimmune thyroid disease: autoimmune gastritis association's possibility]. / Enfermedad tiroidea autoinmunitaria: posibilidad de asociación a gastritis autoinmunitaria.

INTRODUCTION: A high prevalence of parietal cell antibodies (PCA) has been reported in children with autoimmune thyroid disease (AITD). The aim of this study was to determine the prevalence of autoimmune gastritis markers among children diagnosed as AITD. PATIENTS AND METHODS: We studied 26 patients with AITD. Basal samples were taken to determine: hemogram, vitamin B12 and folic acid plasmatic levels, gastrin plasmatic levels, and PCA's determination. Other autoimmune disease comorbidity were also studied. RESULTS: Free T4 and TSH values were normal, with hormonal substitutive treatment. Hb, MCV, HCM, vitamin B12, folic acid and gastrin were in normal range for all 26 patients. We reported 6 cases diabetes mellitus type 1 and 2 of celiac disease. A single patient was PCA positive. It was a 14-year-old hyperthyroid girl without any other autoimmune disease. CONCLUSIONS: AITD in childhood and adolescence is associated with other autoimmune diseases, specially DM1 and CD. PCA becomes an early and sensitive marker to detect autoimmune gastritis.

[Parenteral periferic nutrition: non surgical indications]. / Indicaciones no quirúrgicas de la nutrición parenteral periférica.

INTRODUCTION: Peripheral Parenteral Nutrition, defined as a mixture of micronutrients, vitamins and minerals with lower osmolarity of 800 mOsm/L, it avoids the risk of the central catheter. It has traditionally been used in postoperative patients, but really medical conditions can also benefit from it either as complementary, or as the only one source of nutrients, since a high number of patients require less caloric intake than previously believed. OBJECTIVE: Evaluation of the use of peripheral parenteral nutrition in non postoperative hospitalized patients, reasons for its prescription and duration. MATERIAL AND METHODS: 368 patients who required peripheral parenteral nutrition were studied by the Nutrition Support Unit for 54 months, in a Tertiary Hospital of 1,560 beds, from all, specialties excluding postoperative patients. The study include the mechanisms that led to its use in all its forms: the only one nutritional support or complementing insufficient Enteral Nutrition or Oral Diet. RESULTS: Oncology and Critical Care were the most prescribed pathologies, followed by Pancreatitis, Inflammatory Bowel Disease and HIV and a miscellany of clinical pathologies. Gastrointestinal pathology (pain, diarrhea or vomiting) was the most frequent cause, both in critically ill as in non-critical patients. CONCLUSIONS: Although enteral route is preferred and raised primarily in most patients studied, there are many causes that might impair or nullify it. Peripheral parenteral nutrition is an alternative when caloric intake is impossible or insufficient or refused by the patient, as it minimizes the complications of the central catheter.
