ASSOCIATION BETWEEN LOW BONE MINERAL DENSITY, METABOLIC SYNDROME AND SEX STEROIDS DEFICIENCY IN MEN

An Analysis of Primary Hyperparathyroidism in Individuals Diagnosed with Multiple Endocrine Neoplasia Type 2

Background: Primary hyperparathyroidism (PHPT) represents a multi-faced disease with a wide spectrum of manifestations. Familial forms of PHPT (affecting up to 10% of the cases) involve a particular category that encompasses a large range of hereditary syndromes, including parathyroid hyper-function, frequently in the setting of a multi-glandular disease. Objective: The aim was to analyze the most recent findings regarding PHPT in multiple endocrine neoplasia type 2 (MEN2) to a better understanding of the timing with respect to the associated ailments, MEN2-related PHPT (MEN2-PHPT) clinical and genetic particularities, optimum diagnostic, and overall management, particularly, surgical outcomes. Methods: This was a PubMed-based compressive review with regard to the latest data published in English from January 2020 until January 2025, using the following keywords: "primary hyperparathyroidism" and "multiple endocrine neoplasia", "multiple endocrine neoplasia type 2", "MEN2", or "MEN2A". We included original full-length studies of any study design that provided clinically relevant data in MEN2-PHPT and excluded reviews, meta-analysis, and case reports/series. Results: A total of 3783 individuals confirmed with MEN2 or RET pathogenic variants carriers were analyzed across 14 studies that provided data on PHPT. The prevalence of MEN2-PHPT subjects varied between 7.84% and 31.3%, with particularly low rates in non-index patients (3.8%). PHPT was the first syndrome manifestation in 0.9% of MEN2 patients. In terms of gender distribution, females represented 42.85% or 54.9% (similar rates between women and men, and only a single cohort showed a female rate up to 80%). Most subjects were diagnosed with PHPT and underwent surgery in the third or fourth decade of life. The highest median age at MEN2 diagnosis was 42 years. The youngest patients were RET pathogenic variants carriers who underwent (genetic) screening with median ages of 12 or 14 years. RET pathogenic variants analysis (n = 10/14 studies) showed that 16.67% of patients with p.Cys634Arg and 37.5% of those with p.Cys611Tyr had symptomatic PHPT, while those with p.Cys618Phe and p.Leu790Phe were asymptomatic. Timing analysis with respect to the medullary thyroid carcinoma diagnosis showed synchronous PHPT diagnosis in 80% and metachronous in 10% of MEN2 patients; with respect to MEN2-pheochromocytoma, synchronous diagnosis of PHPT was found in 56%, while pheochromocytoma was identified before PHPT in 22% of the cases and after PHPT in 22%. Studies (n = 10/14, N = 156 subjects with MEN2-PHPT) on parathyroidectomy identified that 72.7% to 100% of the individuals underwent surgery, typically performed in adulthood, at ages spanning from a mean of 34.7 to 48.5 years. The post-surgery outcomes varied (e.g., the rate for persistent PHPT was of 0%, 8% to 16.7%; recurrent PHPT of 12.5% to 23%; permanent hypoparathyroidism of 33% to 46%; permanent unilateral vocal cord palsy of 0% up to16.7%). Data regarding the number of involved glands (n = 7, N = 77): the prevalence of multi-glandular disease was pinpointed between 12.5% and 50%. Conclusions: MEN2-PHPT involved unexpected high rates of single-gland involvement (from 33.3% to 87.5%), probably due to an early detection across genetic screening. Traditional female higher prevalence in PHPT was not confirmed in most MEN2 cohorts. As expected, a younger age at PHPT diagnosis and surgery than seen in non-MEN2 patients was identified, being tidily connected with the syndromic constellation of tumors/malignancies. Overall, approximately, one out of ten patients were further confirmed with MEN2 starting with PHPT as the first clinically manifested element.

Association between Metabolic Syndrome and Musculoskeletal Status: A Cross-Sectional Study of NHANES

Objective

The metabolic effects of metabolic syndrome (MetS) on musculoskeletal metabolism are controversial. This study explored the effect of MetS on bone mineral density (BMD) and muscle quality index (MQI).

Methods

Data from the NHANES database from 2011 to 2014 were extracted, and nonpregnant participants aged 45-59 years were included. The included data were first weighted by complex sampling, and then, the effect of MetS on BMD and MQI was analyzed using multifactorial linear regression. We then performed a stratified analysis by gender and BMI classification. Moreover, a mediation analysis of MetS on BMD was conducted, with MQI as a mediating variable. A propensity score matching analysis method with a complex sampling design was additionally performed to verify the stability of the results.

Results

A total of 1943 participants were eventually included. After adjusting for covariates, the results of linear regression show that MetS is associated with elevated pelvic BMD (beta = 0.03; 95% CI = 0.01, 0.06; P=0.02) and reduced MQI, especially arm MQI (beta = -1.02; 95% CI = -1.27, -0.77; P < 0.0001). MetS is more associated with BMD in women, MQI in normal or heavyweight, and BMD in lightweight, according to stratified analysis. MQI explains the indirect effect of MetS on BMD (beta = 0.007; 95% CI = 0.003, 0.010).

Conclusion

This study provides evidence that MetS elevates BMD and reduces MQI, and further, that there is a mediating effect of MQI on elevated BMD.

Association of total testosterone status with bone mineral density in adults aged 40-60 years

Objective

Evidence linking total testosterone and bone mineral density (BMD) in adults is very limited. According to our review of the literature, only a few reports have focused on the relationship between total testosterone and bone mineral density in adults. Therefore, the purpose of this study was to determine the relationship between total testosterone and total bone mineral density in adults aged 40–60 years.

Methods

We used a cross-sectional study of a non-institutionalized U.S. population sample from the National Health and Nutrition Examination Survey. A weighted multivariate linear regression model was used to evaluate the relationship between total testosterone and total bone mineral density. Subgroup analyses were further performed.

Results

In multiple regression models adjusted for potential confounders, total testosterone levels were inversely associated with total bone mineral density. However, in the sex-stratified subgroup analysis, the association between total testosterone levels and total bone mineral density was not significant in female adolescents. There was no negative association between total testosterone and total BMD among men, adults 40 to 60 years of age, and other racial/ethnic groups. There is a negative association between total testosterone and total bone mineral density when total testosterone concentration is greater than 500 ng/dL among Non-Hispanic black.

Conclusion

Our statistical results show that the association between total testosterone levels and total bone mineral density varies by gender and race. Elevated total testosterone levels below 500 ng/dL have adverse effects on bone health. Total testosterone concentrations below 500 ng/dL may have no effect on bone health.

Challenges regarding rehabilitation treatment in a case of postpartum spastic paraparesis, secondary to a T9 vertebral fracture on the pathologicallybone operated -case report

Introduction. Pregnancy is a well-known risk factor for asymptomatic hemangiomas discovered incidentally, becoming aggressive or symptomatic, most often in the third trimester of pregnancy, related to hemodynamic and endocrine changes that occur during pregnancy. Many patients experience incomplete spontaneous remission after birth. Material and method. We report the case of a 24-year-old woman, who presented for incomplete paraplegia, pain in the spine, instability of walking of the left lower limb, bilateral plantar paresthesia, possible walking with metal support. Results and discussions. The MRI performed identifies T9 vertebral fracture-compression on pathological bone, T10-T12 vertebral hemangiomas. Conclusions. In order to obtain favorable results, the patient benefited from the support and treatment of a multidisciplinary team: neurosurgeons, imagers, physical and rehabilitation medicine doctors and physiotherapists, and represented a real challenge regarding the complexity of the factors involved.

The importance of early and long-lasting medical rehabilitation in patients with brachial plexus injury

Introduction. Brachial plexus lesions vary in severity, depending on the etiopathogenic mechanism and the level of force to which the plexus is exposed. In the same patient, several nerves of the plexus can be damaged in varying degrees of severity. Brachial plexus injuries lead to upper limb paralysis and disability. Material and Methods. We present the case of a 68-year-old woman diagnosed a year ago with multiple myeloma, clavicular plasmacytoma and secondary spontaneous clavicle fracture. At the same time she presented several dislocations of the shoulder and was diagnosed with brachial plexus palsy after the last dislocation. The patient was hospitalized in our department with a large motor deficit in the upper limb. A comprehensive motor rehabilitation program has been established three weeksafter installing the palsy. Results and discussion. The evolution of the patient was favorable. It was noticed the reduction of the symptoms and slight improvement in motor deficit of the affected upper limb. Thepatient rehabilitation should continue for several months because the nerve regenerates slowly. Conclusion. In patients with brachial plexus injury, motor rehabilitation should be instituted as early as possible and continued for a longer periodoftime until nerve regeneration occurs.It results that early and continuous medical rehabilitation is essential in patients with brachial plexus injury.
