A 37-year old female with Turner's syndrome, iron deficiency anemia and intermittent gastrointestinal hemorrhage is described. Gastrointestinal endoscopy with biopsies, revealed telangiectasia in the duodenal bulb, the cecum and the ascending colon. Endoscopy should be performed in patients with Turner's syndrome and anemia even if there are not signs of active gastrointestinal bleeding.
100 patients with a modified Ivy bleeding time longer than 10 min in the presence of more than 80 x 10(9)/l blood platelets were studied retrospectively. 72 patients had repeated bleeding times between 10 and 20 min or one or more measurements exceeding 20 min, and were considered to have an unquestionable platelet dysfunction. 39 (54%) of these 72 patients were receiving large doses of antibiotics. Nearly one half of the patients on antibiotics had a bleeding tendency, but most of these patients had additional features that may have interfered with platelet function, or a coagulation defect. In the remaining 33 patients, the prolonged bleeding time was associated with von Willebrand's disease, liver disease, leukaemia/myeloproliferative disease, paraproteinaemia or aspirin ingestion. High doses of penicillin seem to be the most common cause of qualitative platelet disorders in general hospital practice.

A 76-year-old man with herpes zoster affecting the 7th thoracic dermatome on the right side was referred for gastroscopy because of anorexia, nausea, vomiting and burning epigastric pain. Lesions were seen along the greater curvature of the stomach suggesting mucosal herpes zoster.
Lymphoid cells from patients with rheumatoid arthritis were compared with those from healthy blood donors and from nonrheumatoid arthritis patients for the ability to manifest in vitro cytotoxicity against target cells in the presence of phytohemagglutinin (PHA) or anti-target cell antibodies. The PHA-induced cytotoxicity in the rheumatoid patient group was significantly lower than that of the blood donors (P less than 0.01) and of the nonrheumatoid patients (P less than 0.05). The rheumatoid arthritis patients appeared to fall into two groups, one with normal and one with distinctly subnormal PHA-induced cytotoxicity. No obvious differences were observed betes, or the proportion in peripheral blood of T lymphocytes (E-RFC) or Fc-receptor-bearing lymphocytes (EA-RFC). There were no significant differences between the groups with regard to antibody-dependent cytotoxicity.
Compliance is of extreme importance in assessing quality of life since lost data never can be retrieved. In order to assess this issue in various studies, a cross-sectional study in cured cancer patients, three prospective trials and a normative study were explored. In the cross-sectional study 82 per cent of the patients completed the questionnaires after one reminder. More females than males answered the questionnaires. The compliance rate varied from 99 per cent to 62 per cent in the prospective studies depending upon time after inclusion. It seems that compliance decreases during follow up, primarily because of disease progression. In one of the prospective studies low compliance rate (approximately 30 per cent) was found in the questionnaire assessing religious issues. In the normative study 68 per cent of the population completed the questionnaire. No gender differences were found, but younger males and elderly women were poor compliers. In conclusion, our data support that most patients complete quality of life questionnaires. It seems that patients with inferior education, reduced physical function and with progressive/terminal disease are low compliers. Introduction of the first quality of life questionnaires to the patients is of great importance. Detailed information about the study should be given and the importance of completing the questionnaires should be underlined.
