RESUMO
BACKGROUND: Weighing risks and benefits is currently the primary criterion for decisions regarding systemic anticancer treatment (SACT) in far advanced cancer patients, also in the modern immunotherapy- and molecular-targeted driven oncology. Decision aids rarely include substantially key concepts of early integrated palliative care (PC) and communication science. We compiled decisional factors (DFs) important for guiding the use of SACT with palliative intent (SACT-PI) and explored these DFs regarding their applicability in routine clinical care. PATIENTS AND METHODS: Clinician (participants: n = 28) and patient (n = 15) focus groups were conducted in an integrated oncology and PC setting. Thematic analysis was used to identify DFs. A Delphi survey of clinicians ranked the importance of DFs in routine decision-making. DFs were aligned with elements of the typical decision-making process, resulting in an eight-step guide for making SACT-PI decisions in clinical practice. RESULTS: Eight focus groups revealed 55 DFs relating to established topics like providing information and risk-benefit analysis, as well as to PC topics like patients' attitudes, beliefs, and hopes; patient-physician interaction; and physician attitudes. Agreement on the relative importance was reached for 34 (62%) of 55 DFs, assigned to five elements: patient/family, clinicians/system, patient-clinician-interaction, information/patient education, risk-benefit weighting/actual decision. These themes are embedded in a potential clinically useful SACT-PI Decision Framework, which includes eight steps: assess, educate, verify, reflect, discuss, weigh, pause, and decide. CONCLUSIONS: The SACT-PI Decision Framework integrates subjective patient factors, interpersonal factors, and PC issues into decision-making. Our findings complement existing decision aids and prompt lists by framing DFs in the context of SACT-PI and enforce the decision 'process', not the decision act. Further research is needed to explore the relative importance of DFs in specific patient situations and test structured decision-making processes, such as our SACT-PI Decision Framework, against standard care.

A case of cavernous haemangioma arising from the superficial palmar arch is described. The initial symptoms were those of a subacute tenosynovitis. Surgical exploration showed that the tumor was not affecting the flexor tendons. It was completely resected and the patient had full recovery of hand function.

Two patients with an osteolytic lesion of the greater trochanter suggesting a malignant bone tumor are presented. Biopsy, microbiological and histological examination suggested a diagnosis of trochanteric tuberculosis. Treatment consisted of multiple surgical debridements and antituberculous chemotherapy. The incidence of similar cases is expected to increase with the rising incidence of tuberculosis.

Twenty-five years prior to presentation a 41-year-old man had a femoral fracture stabilized with a 4.5 mm AO/ASIF steel plate. The femur healed uneventfully and the patient was asymptomatic for the following 20 years. He then noticed a slow-growing swelling of the left thigh associated with a degree of weakness. Radiographs of the femur 25 years after fracture stabilization showed a massive expansive osteolytic process surrounded by a rim of bone. Magnetic resonance imaging (MRI) confirmed the presence of a large tumor. Since malignancy could not be excluded the patient underwent incisional biopsy. The histologic findings were nonspecific. Because of persistent symptoms the lesion was marginally excised. Intraoperatively a folded cotton sponge was found adjacent to the femur. Histopathologic investigation confirmed a foreign body reaction probably related to the retained cotton sponge. Reactive, foreign-body-induced change may mimic bone and or soft tissue malignancies.

A 28-year old woman presented with Léri's disease (melorheostosis) and the rare combination of complex vascular malformations and lymphatic anomalies. Multifocal melorheostosis was segmental and unilateral, located in the left axial and peripheral skeleton, fifth thoracic vertebral body, fifth rib. left upper limb and lumbosacral spine (third lumbar body to first sacral segment). Sacral involvement was associated with spinal canal stenosis. Additionally the patient had multiple nevi and had suffered from left hemiplegia since birth. Lymphangiectasia of the mesentery and thorax led to chylothorax resistant to therapy for which the patient underwent a pleuropericardiectomy. Death ensued due to respiratory failure.

The instruction of the patient with diabetes mellitus, aimed at the mastery of technical elements in self-management, as well as his/her education to a coherent behavior respecting both the quality of metabolic control and the quality of life, are basic elements of diabetes treatment. To neglect them would be a professional error. The physician in charge of a diabetic patient must take into account the knowledge and the capabilities that have been acquired by the patient before, as well as his/her actual demand for information and instruction. Concepts and methods of learning and teaching for diabetic patients that have been developed and applied over the last decade may serve as reference for all levels of health education.

Whereas the importance of changing dietary composition and physical activity for metabolic control in diabetic patients is well respected, pharmacokinetic variables of insulin are often neglected in therapeutic decisions. The ambitious goal of euglycemia can rearly be achieved, however, without a profound knowledge of factors influencing the pharmacokinetics of insulin, such as site of injection, injection technique, miscibility of insulins, dose of insulin, injection volume, local blood flow, etc. Available data indicate that it is of major importance to implement pharmacokinetic aspects in the daily care of the insulin-treated patient.

During fructose, sorbitol, and xylitol perfusions, carbohydrate utilization was studied by continuous indirect calorimetry and compared with glucose utilization during pharmacologic inhibition of endogenous insulin secretion. The experiment was performed in 28 normal volunteers divided into 5 groups (glucose, fructose, sorbitol, xylitol, and saline), each subject being its own control. Insulin suppression was obtained by means of a constant infusion of epinephrine (6 microgram/min) and propranolol (0.08 mg/min). After 90 min, during plasma insulin steady state, each sugar or polyol was infused at a rate of 6 mg/kg/min for 120 min. In contrast with a rise in plasma glucose from 161 +/- 6 mg/dl) to 291 +/- 14 mg/dl during glucose infusion, glucose levels remained unchanged during infusion of the glucose substitutes. Carbohydrate oxidation showed a rise of 24, 65, 76, and 44 mg/min during infusions of glucose, fructose, sorbitol, and xylitol, respectively. Lipid oxidation rates decreased by 7, 20, 33, and 23 mg/min during the same infusions. These results indicate that fructose, sorbitol, and xylitol are oxidized at a higher rate than glucose during suppression of endogenous insulin secretion, without any significant rise in glycemia.
