Inform Health Soc Care 2021 Jun 11:1-11. Epub 2021 Jun 11.

School of Nursing, National Taipei University of Nursing and Health Sciences, Taipei, Taiwan.

In neurosurgical or orthopedic clinics, the differential diagnosis of lower back pain is often time-consuming and costly. This is especially true when there are several candidate diagnoses with similar symptoms that might confuse clinic physicians. Therefore, methods for the efficient differential diagnosis can help physicians to implement the most appropriate treatment and achieve the goal of pain reduction for their patients. Read More

The use of telemedicine to support interventional pain care: case series and commentary.

Pain Med 2021 Jun 4. Epub 2021 Jun 4.

Department of Anesthesiology and Perioperative Medicine, University of Pittsburgh, Pittsburgh, Pennsylvania, United States of America.

Incorporating indicated interventions in a multimodal approach to manage musculoskeletal pain has become standard of care. For example, in patients with radicular pain associated with intervertebral disc herniation or lumbar spinal stenosis, epidural steroid injections (ESI) are commonly used and often improve pain and function while avoiding more invasive surgical approaches. Recently, the coronavirus disease 2019 (COVID-19) pandemic has allowed remote evaluations to mitigate COVID-19 transmission using telemedicine. Read More

Int J Mol Sci 2021 May 25;22(11). Epub 2021 May 25.

Metabolic Laboratory, Department of Paediatric Endocrinology and Diabetology with Endocrine, Medical University in Lublin, Prof. A. Gebala Street 6, 20-093 Lublin, Poland.

Achondroplasia (ACH) is a disease caused by a missense mutation in the (fibroblast growth factor receptor 3) gene, which is the most common cause of short stature in humans. The treatment of ACH is necessary and urgent because untreated achondroplasia has many complications, both orthopedic and neurological, which ultimately lead to disability. This review presents the current and potential pharmacological treatments for achondroplasia, highlighting the advantages and disadvantages of all the drugs that have been demonstrated in human and animal studies in different stages of clinical trials.
