Introduction And Objectives: The evolution of surgical approaches to the pituitary region brings benefits to the patient, but also means changes for otolaryngologists, who have to face new difficulties and complications. The objective of this paper was to present our experience in the endoscopic approach to the pituitary region, assessing the difficulties and complications encountered, and to offer possible elements for improvement.
Material And Method: We reviewed the first 40 cases of pituitary approaches we carried out between 2008 and 2011. Interventions were performed by a team of neurosurgeons and otolaryngologists in simultaneous collaboration. We analysed the pathology intervened, complications and difficulties.
Results: There were 37 patients operated on for pituitary tumours and 3 cysts; 34 cases were macroadenomas. The complications were 6 cerebrospinal fluid leaks, 3 with meningitis, 6 diabetes insipidus, 1 pulmonary embolism, 1 hydrocephalus and 4 mild nasal complications.
Conclusions: The frequency and type of complications depend on the extent of the endoscopic approach, patient age, tumour size and suprasellar extension. The use of specific instruments, navigation and preoperative assessment of imaging tests help to minimise complications. Prudent implementation of new approaches, knowledge of techniques and complications, and the analysis of the activity allow further progress in access to skull base pathology.

Activation of δ-opioid receptors blocks allodynia in a model of headache induced by PACAP.

Background And Purpose: Pituitary adenylate cyclase activating polypeptide (PACAP) is a human migraine trigger that is being targeted for migraine. The δ-opioid receptor (δ-receptor) is a novel target for the treatment of migraine, but its mechanism remains unclear. The goals of this study were to develop a mouse PACAP-headache model using clinically significant doses of PACAP; determine the effects of δ-receptor activation in this model; and investigate the co-expression of δ-receptors, PACAP and PACAP-PAC1 receptor.

Kenny-Caffey syndrome 2 (KCS2) is a rare cause of hypoparathyroidism, inherited in an autosomal dominant mode, resulting from pathogenic variants of the gene, which is implicated in intracellular pathways regulating parathormone (PTH) synthesis and skeletal and parathyroid gland development. : The case of a boy is reported, presenting with the characteristic and newly identified clinical, biochemical, radiological, and genetic abnormalities of KCS2. : The proband had noticeable dysmorphic features, and the closure of the anterior fontanel was delayed until the age of 4 years.

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder that affects women of reproductive age and is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology. PCOS is often associated with hormonal imbalances, metabolic dysfunction and comorbid psychiatric disorders, including eating disorders (EDs). The review identifies key hormonal factors-serotonin, leptin, insulin, ghrelin, kisspeptin and cortisol-and their roles in the pathophysiology of PCOS and associated psychiatric symptoms.

Brain tumors present a significant global health challenge, and their early detection and accurate classification are crucial for effective treatment strategies. This study presents a novel approach combining a lightweight parallel depthwise separable convolutional neural network (PDSCNN) and a hybrid ridge regression extreme learning machine (RRELM) for accurately classifying four types of brain tumors (glioma, meningioma, no tumor, and pituitary) based on MRI images. The proposed approach enhances the visibility and clarity of tumor features in MRI images by employing contrast-limited adaptive histogram equalization (CLAHE).

Identifying the prolactin threshold that necessitates pituitary magnetic resonance imaging (MRI) in patients with hyperprolactinemia remains challenging. Therefore, developing standards for serum prolactin level criteria to predict prolactinoma is critical. This study aimed to investigate the correlation between hyperprolactinemia and the presence of pituitary adenoma among Saudi female patients with verified prolactin levels.
