Results of this large prospective single center study confirmed that intragastric balloon is useful and safe method for promoting weight loss. Due to improvement of metabolic parameters, treatment with BIB results in reduction of cardiovascular risk and provides a sustained benefit on liver function in obese patients.

Although replacing burdensome 24-h urine collection with spot urine sampling might not provide the solution in all cases, our results show that for the elements analyzed, spot urine could be a reliable alternative.

The PROMO (preference for once monthly bisphosphonate) Study, conducted in seven hospital centres in Croatia between June 2007 and June 2008, was designed to analyse patient preference for weekly and monthly bisphosphonates in everyday clinical practice where the significant proportion of patients are not completely satisfied with the current osteoporosis treatment. Eligible participants were women with postmenopausal osteoporosis taking weekly bisphosphonates for the last 6 months. Those who agreed to be enrolled were transferred from weekly to monthly ibandronate for the next 6 months. There was no washout period between the two treatment regimens. At the baseline, patients expressed their satisfaction with the weekly treatment. At the end of the study, all patients were asked to complete the five-question survey specially designed for this study. Study population comprised 258 participants. Among 248 patients who completed the study, 244 (98.4%) declared their preference for one of the regimens or they had no preference. Once-monthly regimen was preferred by 231 patients (94.7%), whereas once-weekly regimen was preferred by five patients (2.0%). Eight patients (3.3%) indicated no preference. Furthermore, 93.0% of patients thought that monthly dosing was more convenient. Compared to weekly regimen, monthly dosing was associated with significantly higher satisfaction with the treatment and with significantly less adverse events. In line with these data, 85.9% of patients stated improved quality of life with monthly ibandronate. In summary, the PROMO Study demonstrated strong patient preference for monthly over weekly dosing which is expected to improve suboptimal adherence to weekly bisphosphonates.

IntroductionMerkel cell carcinoma is a rare and aggressive primary cutaneous neuroendocrine malignant tumor. The tumor has a high rate of local recurrence after surgical removal. Spontaneous regression appears to be relatively common in this rare type of tumor.Case presentationWe describe the clinical course, cytological and histological findings of a Merkel cell carcinoma in a 70-year-old Caucasian woman, simultaneously diagnosed with chronic lymphatic leukemia. The tumor showed clinical regression after fine needle aspiration. At primary presentation, the tumor had no apparent leukocyte infiltration, but was completely cleared by T-cell mediated immunity within 3 weeks after fine needle aspiration.ConclusionFine needle aspiration may have acted as a mechanical trigger involved in the activation of cell-mediated immunity, leading to the clinical and histological regression of the tumor. To the best of our knowledge, this is the first case report of spontaneous regression of Merkel cell carcinoma in a patient with a co-malignancy, that is to say, chronic lymphocytic leukemia.
