The clinical features of achondroplasia can cause acute self-limited pain that can evolve into chronic pain. Pain causes a low quality of life, in terms of physical, emotional, social, and school functioning in both adult and children with achondroplasia. We conducted a systematic review according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement to describe prevalence, assessment tools, causes and management strategies of pain in this rare disease. We found that shoulder and knee pain is typically referred during infancy, while knee pain is generally referred around 5-6 years of age. The prevalence of general pain in adolescence can be as high as 90%. Chronic pain in the achondroplasia population increases with age, with up to 70% of adults reporting general pain and back pain. Recognizing the multiple determinants of acute and chronic pain in patients with achondroplasia may enable physicians to better understand and manage this burden, particularly with the advent of new drugs that may modify some of the striking features of achondroplasia.

OBJECTIVE
Pediatric achondroplasia is often associated with conditions requiring neurosurgical intervention, including CSF diversion and multilevel spinal decompression. However, there is a lack of clinical guidelines and reliable estimates of the benefits and risks of these interventions. This study aimed to summarize the literature on the neurosurgical management of pediatric achondroplasia patients in order to aid in determining optimal treatment and standardization of care.
METHODS
A systematic review of peer-reviewed studies with an objective diagnosis of achondroplasia, patient demographic information, and available data on neurosurgical interventions performed before 18 years of age for cervicomedullary compression, spinal stenosis, and hydrocephalus was performed. Study quality and risks of bias were assessed using standardized scores. Independent patient data on surgical indications, outcomes, reoperations, and complication risks were aggregated using means and percentages.
RESULTS
Of 204 records, 25 studies with 287 pediatric achondroplasia patients (mean age 25 ± 36 months) treated for cervicomedullary compression (n = 153), spinal stenosis (n = 100), and obstructive hydrocephalus (n = 34) were evaluated. Symptomatic cervicomedullary compression occurred early in life (mean age 31 ± 25 months), with apnea (48%), T2-weighted MRI cord signal (28%), myelopathy (27%), and delayed motor skills (15%) requiring foramen magnum decompression observed in 99% of patients, as well as cervical laminectomy in 65% of patients. Although 91% of treated patients had resolution of symptoms, 2% mortality, 9% reoperation, and 21% complication rates were reported. Spinal stenosis was treated in relatively older children (mean age 13 ± 3 years) with laminectomy (23%), as well as with instrumented fusion (73%) for neurogenic claudication (59%), back pain (15%), and sciatica (8%). Although 95% of patients had symptom resolution after surgery, 17% reported complications and 18% required reoperation. Of the hydrocephalus patients (mean age 56 ± 103 months), half were treated with endoscopic third ventriculostomy (ETV) and half had a shunt placed for progressive ventriculomegaly (66%), headaches (32%), and delayed cognitive development (4%). The shunted patients had a 3% mortality rate and an average of 1.5 shunt revisions per patient. None of the patients who underwent ETV as the primary procedure required a revision.
CONCLUSIONS
Neurosurgical intervention for pediatric achondroplasia conditions, including cervicomedullary compression, spinal stenosis, and hydrocephalus, is associated with high recovery rates and good outcomes. However, complications and reoperations are common. Further studies with follow-up into adulthood are needed to evaluate the long-term outcomes.

Review
BACKGROUND
Achondroplasia is the most common form of skeletal dysplasia. Recent advances in therapeutic options have highlighted the need for understanding the burden and treatment landscape of the condition. This systematic literature review (SLR) aimed to identify health-related quality of life (HRQoL)/utilities, healthcare resource use (HCRU), costs, efficacy, safety and economic evaluation data in achondroplasia and to identify gaps in the research.
METHODS
Searches of MEDLINE, Embase, the University of York Centre for Reviews and Dissemination (CRD), the Cochrane Library and grey literature were performed. Articles were screened against pre-specified eligibility criteria by two individuals and study quality was assessed using published checklists. Additional targeted searches were conducted to identify management guidelines.
RESULTS
Fifty-nine unique studies were included. Results demonstrated a substantial HRQoL and HCRU/cost-related burden of achondroplasia on affected individuals and their families throughout their lifetimes, particularly in emotional wellbeing and hospitalisation costs and resource use. Vosoritide, growth hormone (GH) and limb lengthening all conferred benefits for height or growth velocity; however, the long-term effects of GH therapy were unclear, data for vosoritide were from a limited number of studies, and limb lengthening was associated with complications. Included management guidelines varied widely in their scope, with the first global effort to standardise achondroplasia management represented by the International Achondroplasia Consensus Statement published at the end of 2021. Current evidence gaps include a lack of utility and cost-effectiveness data for achondroplasia and its treatments.
CONCLUSIONS
This SLR provides a comprehensive overview of the current burden and treatment landscape for achondroplasia, along with areas where evidence is lacking. This review should be updated as new evidence becomes available on emerging therapies.

PURPOSE
Skeletal dysplasia are heterogeneous conditions affecting the skeleton. Common nutrition issues include feeding difficulties, obesity, and metabolic complications. This systematic scoping review aimed to identify key nutrition issues, management strategies, and gaps in knowledge regarding nutrition in skeletal dysplasia.
METHODS
The databases Ovid MEDLINE, Ovid EMBASE, Ebsco CINAHL, Scopus, and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews were searched. Reference lists and citing literature for included studies were searched. Eligible studies included participants with skeletal dysplasia and described: anthropometry, body composition, nutrition-related biochemistry, clinical issues, dietary intake, measured energy or nutrition requirements, or nutrition interventions.
RESULTS
The literature search identified 8509 references from which 138 studies were included (130 observational, 3 intervention, 2 systematic reviews, and 3 clinical guidelines). Across 17 diagnoses identified, most studies described osteogenesis imperfecta (n = 50) and achondroplasia or hypochondroplasia (n = 47). Nutrition-related clinical issues, biochemistry, obesity, and metabolic complications were most commonly reported, and few studies measured energy requirements (n = 5).
CONCLUSION
Nutrition-related comorbidities are documented in skeletal dysplasia; yet, evidence to guide management is scarce. Evidence describing nutrition in rarer skeletal dysplasia conditions is lacking. Advances in skeletal dysplasia nutrition knowledge is needed to optimize broader health outcomes.

BACKGROUND
The increase in paternal age and the percentage of births after assisted reproductive technologies (ART) may have consequences on offspring and society's position regarding access to ART must be questioned. Most countries recommend limiting ART to men under 60 years. What is the rationale for this threshold?
OBJECTIVE
This systematic review assesses scientific arguments to establish links between paternal age, male fertility, and offspring health.
MATERIAL AND METHODS
Using the PRISMA guidelines, this systematic review of the literature analyzed 111 articles selected after screening PubMed, ScienceDirect, and Web of Science for articles published between January 1, 1995 and December 31, 2021.
RESULTS
A strong correlation was highlighted between advanced paternal age and a decrease of some sperm parameters (semen volume and sperm motility) and infant morbidity (exponentially increased incidence of achondroplasia and Apert syndrome, and more moderately increased incidence of autism and schizophrenia). The impact of paternal age on pregnancy and fetal aneuploidy rates is more controversial. No association was found with spontaneous abortion rates.
DISCUSSION AND CONCLUSION
The scientific parameters should be explained to older parents undergoing ART. And for countries that discuss a limit on paternal age for access to ART, the debate requires consideration of social and ethical arguments.
