Primary Empty Sella (PES) syndrome is an increasingly common disorder, mostly diagnosed as an incidental finding during brain imaging scans. We intended to review the clinical management and hormonal profile of patients with PES.

Hypogonadism is a common comorbidity associated with HIV-1 that is more prevalent among infected individuals over the age of 45. The underlying mechanisms are unknown, but both combined antiretroviral therapeutics and HIV-1 proteins, such as trans-activator of transcription protein (Tat), dysregulate steroid-synthetic mechanisms including lipid storage/synthesis and mitochondrial function. Thus, Tat expression may accelerate age-related comorbidities partly by impairing endocrine function. Few studies exist of Tat-mediated behavioral deficits in aged animals and effects of endocrine status have not been investigated. Accordingly, we tested whether conditional Tat expression in aged (~ 1.5 years old), female, Tat-transgenic [Tat(+)] mice increases anxiety-like behavior, impairs cognition, and augments mechanical allodynia, when compared to age-matched controls that do not express Tat protein [Tat(-)]. We further tested whether aged mice that maintained their endocrine status (pre-estropausal) were more resilient to Tat/age-related comorbidities than peri- or post-estropausal mice. Tat and endocrine aging status exerted separate and interacting effects that influenced anxiety-like and cognitive behaviors. Peri- and post-estropausal mice exhibited greater anxiety-like behavior in the elevated plus-maze and impaired learning in the radial arm water maze compared to pre-estropausal mice. Irrespective of estropause status, Tat(+) mice demonstrated impaired learning, reduced grip strength, and mechanical allodynia compared to Tat(-) mice. Tat exposure reduced circulating estradiol in post-estropausal mice and increased the estradiol-to-testosterone ratio in pre-estropausal mice. Changes in circulating estradiol, testosterone, and progesterone correlated with grip strength. Thus, endocrine status is an important factor in age-related anxiety, cognition, neuromuscular function, and allodynia that can be accelerated by HIV-1 Tat protein.

Reversible posterior leukoencephalopathy syndrome (RPLS) is a rare and heterogeneous clinico-neuroradiological syndrome characterized by headache, altered mental status, seizures, and visual disturbances. Hypertension and immunosuppression are two of the main factors that predispose an individual to RPLS. However, RPLS can develop when no major risk factors are present. RPLS has been reported in pediatric nephrotic patients, but rarely in adults.

The aim of the study was to assess whether administration of a single dose of methylprednisolone in the group patients above 65 years of age will be effective in complex analgesic management after total hip arthroplasty (THA).

Intraarticular injections are widely used to provide pain relief after arthroscopic procedures and minimize the use of opioids. Dexmedetomidine has been proven to potentiate pain relief and postpone the demand for the first analgesic drug when it is used intraarticularly following arthroscopic knee procedures. However, the effects of dexmedetomidine on articular structures have not yet been evaluated. Our aim was to determine the effects of intraarticular dexmedetomidine injection on articular structures such as cartilage and synovium.

Headache and neck pain (cervicalgia) are frequently reported among patients with joint hypermobility but the prevalence and scope of these symptoms has not been studied in the era of contemporary Ehlers-Danlos and hypermobility disorder nosology. We performed a single-center retrospective study on the incidence of head and neck symptoms in 140 patients with hypermobility disorders over a 2-year period. Overall, 93 patients (66%) reported either headache or neck pain with 49 of those (53%) reporting both. Migraine (83%) was the most common headache type among those with headache disorders and cervical spondylosis (61%) the most common pathology among those with neck symptoms. Fifty-nine percent of spondylosis patients who underwent cervical facet procedures reported significant improvement in neck and head symptoms. Of patients with both head and neck complaints, 82% had both migraine and spondylosis, which, when combined with the high response rate to injections raises the possibility of cervicogenic headache. In this large multidisciplinary retrospective study of patients with hypermobility disorders, head and neck symptoms were highly prevalent, with migraine and cervical spondylosis common, often coexisting, and frequently responsive to targeted therapy for the cervical spine suggesting that degenerative spinal pathology may cause or contribute to headache symptoms in some patients with hypermobility disorders.

Intrahepatic cholestasis of pregnancy (ICP) is characterized by pruritus and cholestasis in late pregnancy and results in adverse pregnancy outcomes, including preterm delivery and birth weight, which are affected by the genetic and environmental background. However, until now, the genetic architecture of ICP has remained largely unclear.

A substantial proportion of patients have recently reported pain reduction levels of ≥80% following treatment with Evoked Compound Action Potential (ECAP) spinal cord stimulation (SCS). The additional health-related quality of life (HRQoL) utility gain that can be achieved in this patient group is unclear. The aim of this study is to quantify the HRQoL utility values seen in a remission health state (defined as ≥80% pain reduction) and contrast with more traditional health states of <50% and ≥50% pain relief.

Juvenile idiopathic arthritis [JIA] is a chronic inflammatory disease and an exclusion diagnosis that includes all forms of arthritis that persist more than 6 weeks under the age of 16. Although there is not yet a cure for JIA, recent advances in the therapeutic field have created a more hopeful present and future for the patients. In the past, therapies for JIA have depended on non-steroidal medication, conventional synthetic disease modifying antirheumatic drugs and corticosteroids. However, over the last decades, the advent of biologic therapies in JIA contributed to the preservation of functional activity, control of pain, avoidance of joint damage and extra-articular manifestations. Furthermore, over the last years, international institutions such as the American College of Rheumatology have released recommendations and guidelines for rheumatologists for optimal JIA management. All the above, have revolutionized the treatment of JIA with promising outcomes. To this end, we review and discuss appropriately the relevant literature.

Aquagenic urticaria (AU) is a rare skin condition in which dermal contact with water serves as a trigger of urticaria and pruritus. To make a diagnosis, a water challenge test is useful. We herein report a 16-year-old Japanese boy diagnosed with AU by water provocation test. The induced skin lesion histologically showed prominent degranulation of mast cells and lymphocytic infiltration throughout the dermis. This is the second report documenting the histopathological features of AU.
