Olfactory Function and Olfactory Bulb Volume in Acromegaly Patients

2019-10-29 14:36:38 | BioPortfolio

Summary

A prospective, controlled, single blinded study was planned. 20 patients with Acromegaly (Acromegaly Group) and 20 healthy subjects (Control Group) were planned to include in the study. Connecticut Chemosensory Clinical Research Center (CCCRC) test was applied to evaluate olfactory functions. Olfactory bulb(OB) volumes were measured with a 1.5 T General Electric Signa Excite MRI scanner.

Description

Acromegaly patients were assessed at the Endocrinology Department for their clinical symptoms, and the nasal examination and olfactory evaluation were done at the Department of Otorhinolaryngology. OB volume was evaluated by a single blinded radiologist. Control group patients that had similar demographical characteristics with the Acromegaly Group were recruited in the study.

The CCCRC test is composed of n-butanol odor threshold test and odor identification test. Olfactory tests were scored out of 7 (0: worst, 7: best olfaction) and mean score was calculated as the total CCCRC test score. OB measurements were done individually on the right and left olfactory bulbs and the mean OB volume was calculated in cubic millimeters.

Developing a Simple Recognition System of Acromegaly

We will compare the features of 3D stereophotography of acromegaly patients with that of healthy people. We hope to develop a computerized model to help screening acromegaly patients for e...

Safety and Efficacy of Octreotide Long Acting Release (LAR) in Treatment Naïve Acromegalic Patients

Currently, the first line treatment for acromegaly is surgery, in order to remove the adenoma causing overproduction of growth hormone which leads to acromegaly. Octreotide LAR is approved...

Acromegaly - Before and After Treatment

The aim of the study is to investigate sleep apnea, circulation and metabolism in acromegaly before and after surgery and/or medical treatment.

Preoperative Octreotide Treatment of Acromegaly

The purpose of this study is to investigate whether 6 months preoperative treatment with the somatostatin analogue octreotide improves the surgical outcome in patients with acromegaly.

Prevalence of Acromegaly in a Diagnostic Consultation for Sleep Apnea Syndrome

Prevalence of sleep apnea syndrome in patients with acromegaly is about 70%. It seems that comorbidities of arterial hypertension or type 2 diabetes are more severe in patients with acrome...

Persistent inflammation and endothelial dysfunction in patients with treated acromegaly.

Acromegaly is characterized by an excess of growth hormone (GH) and insulin like growth-factor 1 (IGF1). Cardiovascular disease (CVD) risk factors are common in acromegaly and often persist after trea...

Development and assessment of machine learning algorithms for predicting remission after transsphenoidal surgery among patients with acromegaly.

Preoperative prediction of transsphenoidal surgical (TSS) response is important for determining individual treatment strategies for acromegaly. There is currently no accurate predictive model for TSS ...

Effects of Pegvisomant and Pasireotide LAR on vertebral fractures in acromegaly resistant to First-Generation SRLs.

Osteopathy is an emerging complication of acromegaly. In somatostatin receptor ligands (SRL)-resistant patients, Pegvisomant (PegV) and Pasireotide LAR (Pasi) are used for acromegaly treatment, but th...

A Consensus on the Diagnosis and Treatment of Acromegaly Comorbidities: An Update.

The aim of the Acromegaly Consensus Group was to revise and update the consensus on diagnosis and treatment of acromegaly comorbidities last published in 2013.

Medical and Biotech [MESH] Definitions

The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).

The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE VOLUME plus residual volume.

The volume of the HEART, usually relating to the volume of BLOOD contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is STROKE VOLUME.

Volume of circulating BLOOD. It is the sum of the PLASMA VOLUME and ERYTHROCYTE VOLUME.

The volume of air remaining in the LUNGS at the end of a normal, quiet expiration. It is the sum of the RESIDUAL VOLUME and the EXPIRATORY RESERVE VOLUME. Common abbreviation is FRC.
