The evaluation of changes in maxillofacial bones using cone beam tomography in acromegaly
2022
BACKGROUND: The aim of the study was to evaluate the changes in craniofacial dimensions of newly diagnosed and untreated acromegaly patients, patients with non-functional pituitary adenoma and healthy individuals on Cone Beam Computed Tomography (CBCT). MATERIAL AND METHODS: 50 newly diagnosed acromegaly patients who did not receive any treatment for acromegaly were included in the study (Group A). Twenty patients with nonfunctional pituitary adenoma (Group B) and 30 healthy individuals were included (Group C). Linear, angular and volumetric measurements were performed. RESULTS: Mandibular length showed significant difference in acromegaly patients, and maxillar length statistically signifi…
Validity and reliability of the Turkish version of the orthognathic quality of life questionnaire in patients with dentofacial deformity
2021
Due to the lack of a specific quality of life (QoL) survey on dentofacial deformities (DFD) for Turkish speakers, the present research aimed to perform a translation of the English version of the Orthognathic Quality of Life Questionnaire (OQLQ) into Turkish (the OQLQ-TR) and provide cultural adaptation to the Turkish population. The process of this cross-cultural adaptation followed the six stages given in the guidelines that were proposed by Beaton et al. (2000), which comprised the following: 1) performing the initial translation, 2) synthesizing the translation, 3) performing the back translation, 4) presenting it to the expert committee, and 5) testing the prefinal version. Throughout …
The bite force and craniofacial morphology in patients with acromegaly: A pilot study
2013
Objectives: Acromegaly is a metabolic disorder caused by increased growth hormone secretion. As a consequence of acromegaly some typical craniofacial morphology changes appear. This pilot study was conducted to compare the bite force and the characteristic size and shape of the craniofacial components of acromegalic patients with the healthy Turkish individuals. In additon, the correlations between bite force and craniofacial morphology of patients with acromegaly and control individuals were evaluated. Study Design: The maximum bite force of the participants was recorded with strain-gage transducer. Lateral xray scans were made under standard conditions, in centric occlusion. On cephalogra…
Assessment of the awareness and management of sleep apnea syndrome in acromegaly. The COM.E.TA (Comorbidities Evaluation and Treatment in Acromegaly)…
2011
In 2007 the Italian COM.E.T.A. (COMorbidities Evaluation and Treatment in Acromegaly) study group started to assess the application in a clinical setting of the Versailles criteria for management of acromegaly complications by a first questionnaire focusing on cardiovascular co-morbidities. A further questionnaire on sleep apnea syndrome (SAS) was delivered by the COM.E.T.A. study group to 107 endocrine centers in Italy. The results of our survey suggest that SAS is a well-known comorbidity even if its estimated prevalence is lower than in the literature. Polysomnography is the preferred tool for diagnosis. Control of SAS is considered relevant both for quality of life and co-morbidities. C…
Identification of somatostatin receptor type 5 gene polymorphisms associated with acromegaly.
2011
ObjectiveThe aim of this study was to characterize the genetic variance of somatostatin receptor 5 (SSTR5) and investigate the possible correlation of such variants with acromegaly risk and different disease characteristics.Design and methodsThe SSTR5 gene coding region and 2000 bp upstream region was sequenced in 48 patients with acromegaly and 96 control subjects. Further, three single nucleotide polymorphisms (SNPs) were analyzed in the same group of acromegaly patients and in an additional group of 475 age- and sex-matched controls.ResultsIn total, 19 SNPs were identified in the SSTR5 gene locus by direct sequencing. Three SNPs (rs34037914, rs169068, and rs642249) were significantly ass…
Cornea in acromegalic patients as a possible target of growth hormone action.
2010
Background: GH exerts its effects on many organs and the eye also seems to be a target site, although few authors have investigated the corneal thickness in patients with acromegaly. Aim: To perform a detailed ophthalmological evaluation in acromegalic patients, in relation to disease activity. Material and methods: Twenty-eight acromegalic patients (11 males, 17 females) and 22 voluntary healthy subjects underwent complete metabolic and ophthalmological evaluation, including retinal thickness (RT), central corneal thickness (CCT), and intraocular pressure values (IOP). Results: Significantly greater CCT values were found in all acromegalic patients in comparison with controls (567 vs 528.5…
Janus kinase (JAK) 2 V617F mutation as the cause of primary thrombocythemia in acromegaly with severe visceromegaly and divergence between growth hor…
2012
OBJECTIVE: An increased prevalence of hematological abnormalities is reported in acromegaly, but to date no reports about the presence of the Janus Kinase (JAK) 2 mutation in acromegalic patients have been described. DESIGN: We report the complex clinical presentation of the unique case, never described, of acromegaly due to GH-secreting pituitary adenoma associated with JAK2 V617F mutation. RESULTS: The patient shows primary thrombocythemia and myelofibrosis, due to JAK2 V617F mutation, severe visceromegaly and a peculiar clinical course of the disease characterized by discrepant values of GH and IGF-1 during somatostatin analog (SA) treatment despite a significant reduction in pituitary a…
Efficacy of combined treatment with pasireotide, pegvisomant and cabergoline in an acromegalic patient resistant to other treatments: a case report
2018
Abstract Background The approach to acromegalic patients with persistent acromegaly after surgery and inadequate response to first-generation somatostatin receptor ligands (SRLs) should be strictly tailored. Current options include new pituitary surgery and/or radiosurgery, or alternative medical treatment with SRLs high dose regimens, pegvisomant (PEG) as monotherapy, or combined therapy with the addition of PEG or cabergoline to SRLs. A new pharmacological approach includes pasireotide, a second-generation SRL approved for patients who do not adequately respond to surgery and/or for whom surgery is not an option. No reports on efficacy and safety of combined therapy with pasireotide and p…
Impact of COVID-19 Pandemic on Disease Control Status and Quality of Life of Patients with Acromegaly.
2022
Background and Objectives: Despite the best efforts of healthcare workers and the deployment of alternative healthcare delivery solutions through telemedicine, the pandemic has disrupted standard care for patients with chronic conditions. The long-lasting pandemic has also had a profound impact on the quality of life (QoL) of the majority of patients with chronic illnesses. The management of rare diseases has been particularly challenging. We aimed to evaluate the impacts that the long-lasting pandemic had on the disease control status and QoL in patients with acromegaly. Materials and Methods: Our prospective study included 34 patients from a national referral centre. The baseline SAGIT an…
Central Corneal Thickness in patients with acromegaly
2011
Introduction Acromegaly is hormonal disorder caused by excessive growth hormone (GH) by the pituitary gland, this results in anatomical changes in many organs and also in the eye and specially in cornea. Objective To perform a connection between the disease activity and the corneal changes Matériels et Méthodes In 28 patients with acromegaly and in 22 voluntary healthy the central corneal thickness (CCT) was measured by pachymeter. And the patients were divided in 2 groups: the first (“group A”) contains 13 cases with not controlled acromegaly; and the other one (“group B”) is related to 15 patients with controlled acromegaly Résultats Patients with acromegaly have a central corneal thickne…
