Objective: To explain the effect of craniofacial relations on the development of the sleep apnoea syndrome (SAS) in acromegaly, and to elucidate how the activity of acromegaly affects the severity of SAS. Design: Prospective observational study. Methods: Cephalometry and sleep ventilation measurements were performed in 26 acromegalic men and in 96 men with SAS. Results: SAS was found in 20 acromegalic men. Compared with non-acromegalic men with SAS, patients with acromegaly and SAS were found to have: enlargement of almost all linear dimensions; increased angle indicating mandibular protrusion; increased difference between maxillary and mandibular protrusion; articular angle decrease; soft palate lengthening; and pharyngeal airway space (PAS) enlargement in the palatal and uvular-tip planes. A comparison of acromegalic men with and without SAS revealed no significant difference in the craniofacial skeleton, although there was a narrowing of the minimal PAS (MinPAS) and of PAS in the uvular-tip plane in patients with SAS. SAS was more frequent in the patients with active acromegaly. MinPAS in the patients with active acromegaly was narrower than in those without disease activity. Conclusion: Skeletal abnormalities in acromegalic men with SAS were different from those in SAS patients without acromegaly. Upper airway narrowing due to changes in pharyngeal soft tissues takes a more relevant share in the development of SAS in acromegalic men than skeletal anomalies.
Introduction: Collection of valid data in patients with hematologic malignancies remains a challenge. Especially low grade malignancies require long term follow-up and valid high quality data. The RMG registry was established in 2007 and has become one of the flagship projects of the Czech Myeloma group. To date, four parts of the registry are active - module for multiple myeloma (MM), monoclonal gammopathies of undetermined significance (MGUS), AL amyloidosis (ALA) and Waldeströms macroglobulinemia. The later two has been started in 2014. Aim: To analyze current status of the registry in terms of amount of contained data. Methods: All patients must sign a written consent before entering their data into the registry. Data concerning diagnosis, demography, treatment and survival are regularly collected and updated into the registry via online system at https://trials.cba.muni.cz/trialdb2/interface_forms/login_rmg.asp. The data from MGUS patients are retrospective and prospective, data from MM patients are only prospective (since 2007). Registry is regularly monitored and data are validated by an external monitor. Results: There are 22 participating centers as of July 2015 (18 from the Czech Republic and 4 from Slovakia). Data from 4549 patients with MM, 2168 with MGUS, 121 patients with WM and 22 with ALA have been collected. Together 6860 patients have been included in the registry as of July 2015. Median follow-up of MGUS patients is 4 years (0-35 years) and median follow-up for MM patients is 2 years (0-32 years). The huge amount of data allowed publication of treatment results of MM patients treated with bortezomid and thalidomide in the Czech Republic and regular analysis of patients treated with lenalidomide. Novel prognostic models for MGUS progression and asymptomatic myeloma have been created based on registry data (manuscripts submitted). Conclusion: The RMG is one of the largest registries in Europe. Its biggest advantage is collection of validated updated data which can be used to create rapid analyses in order to react to changing myeloma field. It helps us to create new guidelines and serves as a potent research tool. It can be also used to negotiate reimbursement with healthcare insurance companies and government regulatory authorities for novel drugs implementation into treatment standards.

The RMG represents a data basis that makes it possible to monitor the disease course in patients with monoclonal gammopathies on the population level.Key words: Registry of Monoclonal Gammopathies - RMG - registries - monoclonal gammopathies - CLADE-IS - data visualisation - database.
The primary aim of this study was to assess whether there exists a relationship between lumbar cerebrospinal fluid (CSF) pressure and intracranial blood flow velocities as measured by transcranial Doppler sonography (TCD) in children with scaphocephaly. Another aim was to compare pre- and postoperative TCD. Using a transducer, lumbar CSF pressure (LP) was assessed in 21 children with scaphocephaly. TCD was performed, and the pulsatility index (PI) and the resistance index (RI) were obtained before and after cranioplasty. In 17 children LP was higher than the reference values. No significant differences were found in PI and RI indices before and after cranioplasty. LP values were significantly higher in children older than 6 months. There was no association between LP and PI and RI indices. In children with scaphocephaly a higher LP can be expected with age. Moreover, TCD is not a reliable tool in predicting abnormal LP values.
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.
