The clinical course of Rathke's cleft cysts in pediatric patients: impact on growth and pubertal development

Pediatric Pituitary Adenomas and Cysts: A 46-Year Population-Based Analysis

Context

Pituitary adenomas and cysts are rare in pediatric patients and improved understanding can guide management recommendations.

Objective

To report incidence, presentation, management, and outcomes in a pediatric population-based cohort with pituitary adenomas and cysts, and to explore the relationship between these lesions and brain magnetic resonance imaging (MRI) rates, as well as lesion size and headaches with disease progression.

Methods

In this retrospective cohort study of pediatric patients (≤18 years) with incident pituitary adenomas and cysts in Olmsted County, MN, from 1976 to 2021, 234 unique patients were identified using diagnostic codes through the Rochester Epidemiology Project, with 37 confirmed cases of pituitary adenoma or cyst included. Incidence rates were calculated using census data. Descriptive statistics were used for extracted clinical data.

Results

Incidence of pediatric adenomas and cysts was 2.29 cases per 100 000 person-years. Of the 37 cases, 68% were nonfunctioning adenomas or cysts, 27% were prolactinomas, and there was 1 each of growth hormone (GH)- and thyrotropin (TSH)-secreting adenomas. Median lesion diameter was 5.5 mm (IQR, 4.0-8.0). Median follow-up was 7.4 years (IQR, 4.5-15.4). Four patients had disease progression which stabilized with second-line therapy. Brain MRI rates did not correlate with lesion incidence. No clinically meaningful relationship was found between lesion size or headache and disease progression.

Conclusion

Pituitary adenomas and cysts are rare in pediatric patients. Most are small, nonfunctioning, and stable on long-term follow-up. Larger studies on small nonfunctioning pituitary lesions are needed to enhance understanding of their natural history and develop long-term management recommendations.

Pediatric Orbital and Skull Base Pathology

Pediatric orbital and skull base pathologies encompass a spectrum of inflammatory, sporadic, syndromic, and neoplastic processes that require a broad and complex clinical approach for both medical and surgical treatment. Given their complexity and often multicompartment involvement, a multidisciplinary approach for diagnosis, patient and family counseling, and ultimately treatment provides the best patient satisfaction and clinical outcomes. Advances in minimally invasive surgical approaches, including endoscopic endonasal and transorbital approaches allows for more targeted surgical approaches through smaller corridors beyond more classic transcranial or transracial approaches.

Rathke's Cleft Cyst Leads to Stunted Growth in Children: A Case Report Written With the Help of ChatGPT

In recent times, ChatGPT has become a globally renowned AI tool, revolutionizing academic research by offering innovative methods and opportunities. The integration of AI into various domains is a prevailing topic, focusing on optimizing its utility. This article presents a case study of a child with Rathke's cyst, primarily exhibiting symptoms of growth and developmental delay. The patient's self-perception of stunted growth, coupled with previous assessments indicating partial growth hormone deficiency, prompted further investigation. Laboratory assessments revealed low growth hormone and insulin-like growth factor levels, while imaging disclosed a pituitary lesion. Rathke's cyst was postulated as the probable cause of the growth hormone deficiency. Rathke's cyst remains a rare medical condition with substantial research knowledge gaps. In this article, we synergize ChatGPT responses with a comprehensive case report of a child with Rathke's cyst as the primary symptom-growth and developmental delay. We explore the methods and feasibility of employing ChatGPT within this case report.

The Congenital and Acquired Mechanisms Implicated in the Etiology of Central Precocious Puberty

The etiology of central precocious puberty (CPP) is multiple and heterogeneous, including congenital and acquired causes that can be associated with structural or functional brain alterations. All causes of CPP culminate in the premature pulsatile secretion of hypothalamic GnRH and, consequently, in the premature reactivation of hypothalamic-pituitary-gonadal axis. The activation of excitatory factors or suppression of inhibitory factors during childhood represent the 2 major mechanisms of CPP, revealing a delicate balance of these opposing neuronal pathways. Hypothalamic hamartoma (HH) is the most well-known congenital cause of CPP with central nervous system abnormalities. Several mechanisms by which hamartoma causes CPP have been proposed, including an anatomical connection to the anterior hypothalamus, autonomous neuroendocrine activity in GnRH neurons, trophic factors secreted by HH, and mechanical pressure applied to the hypothalamus. The importance of genetic and/or epigenetic factors in the underlying mechanisms of CPP has grown significantly in the last decade, as demonstrated by the evidence of genetic abnormalities in hypothalamic structural lesions (eg, hamartomas, gliomas), syndromic disorders associated with CPP (Temple, Prader-Willi, Silver-Russell, and Rett syndromes), and isolated CPP from monogenic defects (MKRN3 and DLK1 loss-of-function mutations). Genetic and epigenetic discoveries involving the etiology of CPP have had influence on the diagnosis and familial counseling providing bases for potential prevention of premature sexual development and new treatment targets in the future. Global preventive actions inducing healthy lifestyle habits and less exposure to endocrine-disrupting chemicals during the lifespan are desirable because they are potentially associated with CPP.
