Precocious Puberty

Dear Colleagues,

Precocious puberty remains a common clinical concern, which can be classified into two main groups: (1) GnRH-dependent and (2) GnRH-independent. Within the GnRH-dependent variety, the idiopathic form primarily affects females and stands as the most prevalent subtype.

Despite the description of precocious puberty in Lawson Wilkin’s Pediatric Endocrinology, the first established textbook in this field (1950 edition, United States), numerous unresolved scientific inquiries persist. Key questions remain, such as the need to define the condition universally, the issue of race- and ethnicity-specific criteria, progression in individuals with GnRH-dependent precocious puberty necessitating treatment, and ‘sustained precocious puberty’. Additionally, there is a need to determine the long-term prognosis for patients with idiopathic GnRH-dependent precocious puberty, with or without treatment.

Over recent decades, advancements in molecular biology have enriched our comprehension of both physiological and precocious puberty. While several genes implicated in precocious puberty have been identified, comprehensive elucidation remains elusive. Queries linger regarding who should undergo genetic screening and the specific characteristics of patients with gene variants, among other concerns.

Moreover, mounting evidence suggests a global acceleration in pubertal development over recent years (Eckert-Lind et al., 2020). Consequently, the re-analysis and validation of historical epidemiological data on puberty, particularly dated studies, have become imperative concerns.

This Special Issue invites physicians to contribute reviews, original articles, commentary/hypotheses, and case reports on precocious puberty and related domains, encompassing:

（1）General Reviews

• Trends in pubertal development over decades;
• Physiology of pubertal development and refined criteria for precocious puberty;
• Recent insights from molecular biology into physiological and pathophysiological pubertal development;
• Clinical etiologies underlying precocious puberty.

（2）Specified Reviews

• Treatment strategies for idiopathic GnRH-dependent precocious puberty;
• Long-term prognoses associated with idiopathic GnRH-dependent precocious puberty;
• Pathophysiology of functional ovarian cysts/McCune–Albright syndrome;
• Therapeutic approaches for McCune–Albright syndrome;
• Rare conditions linked to GnRH-independent precocious puberty;
• Uncommon non-endocrine conditions causing vaginal bleeding in prepubertal children
• Understanding premature thelarche, premature adrenarche, and premature menarche

（3）Other Encouraged Submissions

• Original articles, including retrospective studies;
• Case reports with educational insights, extended follow-up, or precise clinical data;
• Review articles or commentary/hypotheses on aspects of precocious puberty not covered above.

We anticipate contributions that will significantly advance our understanding of precocious puberty and related areas.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Endocrines is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
