To assess the risk of new persistent opioid use in opioid-naïve men undergoing male fertility procedures DESIGN: Retrospective cohort study using a claims database SETTING: TriNetX Diamond Network – a database linking electronic medical record data and claims – assessing men undergoing fertility procedure between 2010 and 2021.

Moderate haemophilia has traditionally been associated with less complications than severe haemophilia. Changes in treatment recommendations have highlighted the burden of moderate haemophilia with a subset of patients with a severe bleeding phenotype. The ankle joint is disproportionally affected by ankle haemarthropathy however the impact has not been evaluated in moderate haemophilia, nor the effect on health related quality of life (HRQoL) or foot and ankle outcomes.

Sulfatide is a sulfated glycosphingolipid that is present abundantly in myelin sheaths of the brain and spinal cord. It is synthesized by a cerebroside sulfotransferase encoded by Gal3st1, which catalyzes the transfer of sulfate from 3'-phosphoadenylylsulfate to galactosylceramide. We previously reported that Gal3st1 gene expression in the spinal cord is upregulated 1 day after intraplantar injection of complete Freund's adjuvant (CFA), indicating that sulfatide is involved in inflammatory pain. In the present study, we found that intrathecal injection of sulfatide led to mechanical allodynia. Sulfatide caused levels of glial fibrillary acidic protein (GFAP) and nitric oxide in the spinal cord to increase. Mechanical allodynia induced by intrathecal injection of sulfatide was blocked by nitric oxide synthase inhibitors and by suppression of astrocyte activation by L-α-aminoadipate. These results suggest that sulfatide-induced mechanical allodynia involved glial activation and nitric oxide production. Blocking selectin, a sulfatide-binding protein, with bimosiamose attenuated sulfatide-induced allodynia and ameliorated CFA-induced mechanical allodynia during inflammatory pain. Finally, elevated levels of sulfatide concentration in the spinal cord was observed during CFA-induced inflammatory pain. The elevated sulfatide levels enhanced selectin activation in the spinal cord, resulting in mechanical allodynia. Our data suggest that sulfatide-selectin interaction plays a key role in inflammatory pain.

Back pain is common and costly, with negative impacts on both individuals and the health care system. Rural, remote, and Indigenous populations are at greater risk of experiencing back pain compared to urban and non-Indigenous populations. Potential barriers to health care access among Canadians with chronic back pain (CBP) have been identified; however, no study has used lived experiences of people with CBP to drive the selection, analysis, and interpretation of variables most meaningful to patients.

Coronary artery spasm constitutes the primary underlying pathology of variant angina. Because provocation of coronary artery spasm may occur with both excess sympathetic and excess parasympathetic stimulation, patients with this disorder have extremely limited options for perioperative pain control. This is especially true for procedures involving extensive abdominal incision/manipulation. Whereas neuraxial analgesia might otherwise be appropriate in these cases, several studies have demonstrated that coronary artery spasm can occur as a result of epidural placement, and therefore, that this may not be an optimal choice for patients with variant angina. This report discusses the case of a patient with a preexisting diagnosis of variant angina who underwent an exploratory laparotomy with large ventral hernia repair and for whom continuous erector spinae plane blocks were successfully used as analgesic adjuncts without triggering coronary artery spasm.

Cluneal neuropathy is encompassed by three distinct clinical entities. Superior, middle and inferior cluneal neuralgia make up the constellation of symptoms associated with cluneal neuropathy. Each has its own variable anatomy. Adjusted incidence rates of superior cluneal neuropathy are 1.6-11.7%. Accurate diagnosis remains challenging due to lack of standardized criteria and the aforementioned variability. Treatment may include therapeutic nerve blocks, ablative techniques, neuromodulation and surgical decompression. Gaps including those related to true incidence and work up exist. Outcomes from interventional studies are limited and mixed due to significant population heterogeneity and non-standardized treatment approaches coupled with very small sample sizes.

To summarize the clinical manifestations, imaging characteristics and experience of surgical treatment of tethered cord syndrome (TCS) accompanied by dermal sinus tract (DST) in adulthoods.

The authors aimed to compare the effects of a one-time ultrasound (US)-guided subacromial corticosteroid injection and three-time ozone (O-O) injection in patients with chronic supraspinatus tendinopathy.

The study aims to assess the incidence and features of temporomandibular joint(TMJ) dysfunction in post-surgical treatment of unilateral zygomaticomaxillary complex(ZMC) fractures.The objectives are:To assess severity of TMJ dysfunction in postoperative cases of ZMC fractures.To create awareness of the same among clinicians.

We assessed whether race or ethnicity was associated with the incidence of high-impact chronic pain (cLBP) among adults consulting a primary care provider for acute low back pain (aLBP).
