[Overcoming therapy resistance in prolactinomas: from perspectives to real clinical practice].

The main treatment option of prolactin-secreting pituitary adenomas is dopamine agonist therapy, which demonstrates prolactin level normalizing and reducing the size of an adenoma in the majority of cases. However, significant amount of patients - about 20% - poorly responds even to high doses of dopamine agonists that is explained by the resistance to therapy. The occurrence of pharmacodynamic characteristics is one of the causes responsible for the development of resistance to typical therapy.

[Acromegaly in the differential diagnosis of hearing loss].

Acromegaly is a multifactorial neuroendocrine disease caused by hyperproduction of growth hormone (GH). In more than 95% of cases the reason of acromegaly the GH-secreting pituitary adenoma. In patients with this neuroendocrine disease, a slowly developing complex of symptom can manifest with concomitant pathological conditions, including auditory function disordersDiagnostic difficulties of acromegaly at the ambulatory stage determine the importance of doctor`s awareness in different medical specialties.

Factors affecting the corneal endothelium after selective laser trabeculoplasty in primary open angle and angle closure glaucoma.

Purpose: To study the factors affecting the corneal endothelium after selective laser trabeculoplasty (SLT) in primary open angle glaucoma (POAG) and primary angle closure glaucoma (PACG).

Method: This prospective interventional study included 56 patients (56 eyes) with POAG and 55 patients (55 eyes) with PACG. All participants received a standard SLT session.

Detection of Primary Angle Closure Glaucoma Progression by Optical Coherence Tomography.

Purpose: To compare the role of spectral-domain optical coherence tomography (SD-OCT) in regard to retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) assessment in the detection of primary angle-closure glaucoma (PACG) and primary open-angle glaucoma (POAG) progression.

Materials And Methods: In the prospective study, 131 subjects with PACG and POAG were examined during 72 months with follow-up visits every 6 months. Visual field (VF) progression was detected using the Guided Progression Analysis (GPA) of the Humphrey visual field analyzer and structural change using SD-OCT while a significant negative trend for the RNFL and GCC was gauged.

[Comparative study of factors associated with the progression of primary open-angle and angle-closure glaucoma].

Purpose: To compare the factors associated with the progression of primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG).

Material And Methods: This prospective study analyses clinical data of POAG and PACG patients followed up for 6 years. The progression of glaucomatous optic neuropathy (GON) was determined using perimetry and spectral optical coherence tomography (OCT).
