Role of Copeptin in Predicting Postoperative Hyponatremia and Hypernatremia in Patients Undergoing Endoscopic Pituitary Adenoma Surgery.

Background And Objectives: Arginine vasopressin (AVP) is an important hormone responsible for maintaining sodium homeostasis after pituitary surgery. The measurement of AVP levels is difficult because of its short half-life (t 1/2 ). Copeptin is a preprohormone of AVP, and it is a more stable peptide, which can be used as surrogate marker for AVP.

Endoscopic Transpterygoid Corridor for Petroclival Tumors: Case Series and Technical Nuances.

Background: The petroclival area is a technically challenging region to operate owing to the proximity of the internal carotid artery (ICA) and the need to obtain gross total excision of tumors in this area as they are often resistant to radiotherapy.

Objective: We present our experience with the endonasal endoscopic transpterygoid approach in managing tumors of the petroclival region and discuss various operative nuances for safer resection.

Materials And Methods: A retrospective study of all consecutive cases of lesions occupying the petroclival region that were operated via endonasal endoscopic transpterygoid approach at our center between January 2016 and December 2021 was performed.

Antenatal care is associated with adherence to iron supplementation among pregnant women in selected low-middle-income-countries of Asia, Africa, and Latin America & the Caribbean regions: Insights from Demographic and Health Surveys.

Anaemia is a global public health problem affecting 800 million women and children globally. Anaemia is associated with perinatal mortality, child morbidity and mortality, mental development, immune competence, susceptibility to lead poisoning and performance at work. The objective of this article is to identify whether antenatal care-seeking was associated with the uptake of iron supplementation among pregnant women, adjusting for a range of covariates.

Large Pituitary Adenoma: Strategies to Maximize Volumetric Resection Using Endoscopic Endonasal Approaches and an Analysis of Factors Limiting Resection.

Background: Large pituitary adenomas (LPAs), which constitute ∼5%-14% of all pituitary adenomas, are considered challenging tumors owing to their locally aggressive behavior, low gross total resection rate, and high prevalence of visual deficits and hypopituitarism. We evaluated the utility of various extended endoscopic endonasal approaches in maximizing the resection of LPAs and studied the factors affecting the extent of surgical resection.

Methods: A retrospective study of all LPAs (defined as a minimum diameter >3 cm and tumor volume >10 cm) treated via an endoscopic endonasal approach between January 2015 and December 2020 was performed.

Endoscopic Endonasal Excision of a Meckel's Cave Dermoid Cyst.

Background: Meckel's cave dermoid cyst is an extremely rare and a technically challenging lesion. The objective of the study is to show that endoscopic endonasal approach (EEA) has recently emerged as a better alternative to transcranial approach for this formidable tumor, owing to minimal retraction-related morbidity.

Method: A 52-year-old male presented with numbness over the right side of the face and temporal area for the last 3 years.

Endoscopic Endonasal Excision of a Complex Craniopharyngioma Operated Multiple Times by Transcranial Route.

Background: Complex craniopharyngiomas pose a significant surgical challenge owing to its proximity to critical structures and its intrinsic nature to resist radical excision.

Objective: To show that endoscopic endonasal approach (EEA) is potentially a better alternative to transcranial approach in tumors that have been operated multiple times by transcranial route for achieving radical excision with minimal morbidity.

Materials And Methods: A 32-year-old male previously operated twice through interhemispheric approach for craniopharyngioma presented with blurring of vision accompanied by headache and intermittent diplopia.
