Ventricular standstill complicating left heart catheterization in the presence of uncomplicated right bundle branch block.

We report the unusual occurrence of complete heart block during attempted right coronary artery cannulation in a patient with pre-existing uncomplicated right bundle branch block (RBBB). This complication occurred due to accidental impingement of the Judkin's right coronary catheter on the left bundle when it transiently slipped across the aortic valve. The block resolved without any complication.     

Tested communication strategies for providing information to patients in medical consultations: A scoping review and quality assessment of the literature

ObjectivesTo systematize the scientific knowledge of empirically tested strategies for verbally providing medical information in patient-physician consultations.MethodsA scoping review searching for terms related to physician, information, oral communication, and controlled study. Four pairs of reviewers screened articles. For each selected study, we assessed the quality and summarized aspects on participants, study, intervention, and outcomes. Information provision strategies were inductively classified by types and main categories.ResultsAfter screening 9422 articles, 39 were included. The methodological quality was moderate. We identified four differently used categories of strategies for providing information: cognitive aid (n = 13), persuasive (n = 8), relationship- (n = 3), and objectivity-oriented strategies (n = 4); plus, one “mixed” category (n = 11). Strategies were rarely theoretically derived.ConclusionsCurrent research of tested strategies for verbally providing medical information is marked by great heterogeneity in methods and outcomes, and lack of theory-driven approaches. The list of strategies could be used to analyse real life communication.Practice implicationsFindings may aid the harmonization of future efforts to develop empirically-based information provision strategies to be used in clinical and teaching settings.     

Combination chemotherapy (M-2) protocol (BCNU, cyclophosphamide, vincristine, melphalan, and prednisone) for Waldenstrom macroglobulinemia: preliminary report

Fourteen consecutively referred, symptomatic patients with Waldenstrom's macroglobulinemia (ages 52-87 yr) have been treated with the 5-drug M-2 protocol (BCNU, cyclophosphamide, vincristine, melphalan, and prednisone). Three patients were previously treated and 11 patients were untreated. The majority of patients were symptomatic from hyperviscosity. All patients have responded to therapy. Two patients have achieved complete remissions and 12 patients partial remissions to date. None of the patients with symptomatic hyperviscosity has required plasmapheresis since therapy with the M-2 has been initiated. Lymphadenopathy, hepatosplenomegaly, and anemia have also responded to treatment. Follow-up data are limited, with survival from initiation of therapy with the M-2 ranging from 2+ to 35% mo (median 17+ mo) 2+-40+ mo from time of diagnosis). Combination chemotherapy for Waldenstrom's macroglobulinemia with the M-2 protocol appears to increase the response rate in patients with symptomatic disease. Further survival analysis will be carried out.     

Bone mineral density evaluation of patients with type 2 diabetes mellitus

[Purpose] Diabetes mellitus is a metabolic disorder resulting from a defect in insulin secretion, insulin action, or both. A consequence of this is chronic hyperglycemia with disturbances in carbohydrate, fat and protein metabolism. We investigated whether there is any difference among DM patients and a control group in terms of lumbar and femur BMD (bone mineral density), and standard deviation scores (Z score and T score). [Subjects and Methods] This randomized, prospective, controlled, single-blind study was conducted in the Physical Medicine and Rehabilitation Department Faculty of Medicine, Bezm-i Alem Vakıf University. Patients with type 2 diabetes mellitus were included in the patient groups. Healthy individuals were included in the control group. [Results] A total of 126 patients completed the study (63 in the study group, 63 in the control group). There was no significant difference in the results of the laboratory examinations of the cases. The bone mineral densities of the cases were found to be significantly low in terms of the lumbar (L1–4) T scores in the type 2 diabetes group. [Conclusion] Although osteoporosis is one of the potential complications of type 1 diabetes, its effect on bone mineral density in type 2 DM is controversial. In different studies, the bone mineral density values have increased, decreased or remained normal. With the exception of the lumbar (L1–4) T score, similar results were obtained in this study.Key words: Type 2 diabetes mellitus, Osteoporosis, Bone mineral density     

Lifestyle Management for Enhancing Outcomes after Bariatric Surgery

Bariatric surgery has been safe and effective for treatment of severe obesity and comorbidities like type 2 diabetes mellitus (T2D). Nonetheless, weight loss and health outcomes vary considerably across individuals. Although the factors associated with outcomes are not fully understood, postoperative weight loss following any type of bariatric surgery is largely dependent on the extent to which patients can make and sustain changes in eating and activity. Therefore, lifestyle management including diet, exercise, and behavior modification is critical to helping patients achieve long-term weight loss. Pharmacotherapy and reoperation may also play a role after bariatric surgery. In this article, we highlight recent research findings in all of these areas to provide suggestions for how to enhance outcomes following bariatric surgery. Research on the mechanisms for weight loss and improvements in T2D following the different surgical procedures is needed to support the development of more personalized approaches to the multidisciplinary management of severe obesity.
