A 25-year-old male patient complained of mucoid, watery and nonbloody diarrhea for 4 weeks. Stool volumes and frequency (5 ± 20 per day) varied. Furthermore, he suffered from cramping abdominal pain and weight loss of 10 kg. Physical examination was normal except for the patients fatigued appearance.
Following Mini Nutritional Assessment, the additional measurement of albumin, cholinesterase and hemoglobin allowed a more precise grading of malnutrition. There were significant differences between the disease groups. A deficit of albumin, cholinesterase and hemoglobin was found more often in multimorbid trauma-surgical and internal patients than in neurologic-psychiatric patients.
For the diagnosis, prevention and therapy of malnutrition, it is important to estimate the energy and fluid requirements of an individual patient. To our knowledge, it is unknown how accurately medical doctors can estimate the energy and fluid requirements of patients in a clinical routine situation. Hence, we conducted the following survey. A written face-to-face survey about the energy and fluid requirements of and tube feeding and fluid recommendations for a typical patient was performed with 179 medical doctors. An estimation error of >15% was defined as relevant. The results revealed substantial variations in estimating the energy and fluid needs of the patient. A total of 25% of the participants underestimated the energy requirements, and 47% of the participants underestimated the fluid requirements. In addition, 68% of the participants recommended a daily dose of tube feeding that was <85% of the reference value. A substantial proportion of medical doctors show a lack of knowledge concerning energy and fluid requirements, which demonstrates a need for better medical education with regard to nutrition.
270 patients with a scintigraphically cold thyroid nodule of sonographically increased (n = 34), diminished (n = 72) or neutral (n = 86) echogenity or cystic criteria (n = 78) were subjected to fine needle aspiration biopsy. This revealed unequivocal malignancy in 8 and follicular neoplasia in another 30 patients, 10 of whom proved to have malignomas on further evaluation. A total of 12 papillary and 2 follicular carcinomas, 2 non-Hodgkin lymphomas, 1 sarcoma and the metastasis of a breast carcinoma were diagnosed. The most sensitive criteria for malignancy were diminished echogenity, an inhomogeneous echo pattern and the occurrence of a solitary nodule. The incidence of malignancy was increased among males but not among especially young persons. There was no sonographic feature that would permit omission of fine needle aspiration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
