Mixed Corticomedullary Tumor of the Adrenal Gland: A Case Report and Literature Review.
Adrenal mixed corticomedullary tumors (MCMTs) are composed of an admixture of cortical and medullary cells. Owing to the presence of two distinct components of different embryonic lineage, these tumors are extremely rare. Less than 30 tumors of this type have been reported to date. ⋯ Histology and immunochemical testing were consistent with a mixed corticomedullary tumor. She was monitored annually for recurrence of the tumor. We also performed a comprehensive review of literature of the cases published so far to the best of our knowledge.

Disseminated herpes zoster (DHZ), resulting from the reactivation of the varicella-zoster virus (VZV), typically occurs in immunocompromised persons. To date, only four cases of DHZ following mRNA, viral vector, or inactivated COVID-19 vaccinations have been reported in immunocompetent patients. Herein, we present the first case of DHZ following the protein subunit COVID-19 vaccination (case 1, 64 years old) and a case of DHZ following mRNA COVID-19 vaccination (case 2, 67 years old) in elderly, immunocompetent male patients. ⋯ Oral famciclovir (250 mg, three times/day for 7 days) was administered, and both cases achieved total remission of skin lesions without visceral involvement or severe post-herpetic neuralgia. Our cases demonstrate that DHZ, as a rare cutaneous adverse event in immunocompetent patients, can be secondary not only to mRNA COVID-19 vaccination but also to the protein subunit COVID-19 vaccination. It is speculated that the spike protein of SARS-CoV-2 could be the common trigger for the reactivation of VZV among different types of vaccinations.

From Cells to Environment: Exploring the Interplay between Factors Shaping Bone Health and Disease.
The skeletal system is an extraordinary structure that serves multiple purposes within the body, including providing support, facilitating movement, and safeguarding vital organs. Moreover, it acts as a reservoir for essential minerals crucial for overall bodily function. The intricate interplay of bone cells plays a critical role in maintaining bone homeostasis, ensuring a delicate balance. ⋯ The regulation of bone's physiological functions involves an intricate network of continuous processes known as bone remodeling, which is influenced by various intrinsic and extrinsic factors within the organism. However, our understanding of the precise cellular and molecular mechanisms governing the complex interactions between environmental factors and the host elements that affect bone health is still in its nascent stages. In light of this, this comprehensive review aims to explore emerging evidence surrounding bone homeostasis, potential risk factors influencing it, and prospective therapeutic interventions for future management of bone-related disorders.

Contrary to popular belief, we have known for many years that the endometrium is not a sterile environment and is considered to be a low-biomass milieu compared to the vagina. Numerous trials and studies have attempted to establish a valid sampling method and assess its physiological composition, but no consensus has been reached. Many factors, such as ethnicity, age and inflammation, can influence the microbiome. ⋯ In addition, there is no clearly defined healthy uterine composition yet. At most, only a few taxa have been identified as pathogenic. As sampling and analysis methods become increasingly precise, we can expect the endometrial microbiota to be incorporated into future diagnostic tools and treatments for women's health.

Background and Objectives: Lumbar decompression with fusion surgery is an effective treatment for spinal stenosis, but critical postoperative hematoma is a concern. Bone wax has been widely used to control bone bleeding but it has some drawbacks. This study aimed to evaluate the efficacy of Tableau wax, a bioabsorbable hemostatic material, in patients undergoing spinal fusion surgery through a pilot study design. ⋯ Demographic data, pre- and post-operative hemoglobin levels, blood loss volume, surgical time, Oswestry Disability Index, and EQ-5D scores were recorded. Results: The study showed no significant difference in preoperative and postoperative hemoglobin levels, Oswestry Disability Index, and EQ-5D scores between the groups. However, the Tableau wax group had a significantly lower reduction in hemoglobin levels (1.3 ± 1.0 g/dL) and blood loss (438.2 mL) compared to the Bone wax group (2.2 ± 0.9 g/dL and 663.1 mL, respectively; p = 0.018 and p = 0.022).
