is an organism occasionally isolated in humans but rarely causes bacteremia. We report the first case of cellulitis with bacteremia due to in a patient undergoing mantle-cell lymphoma. A 51-year-old man presented with a two-month history of fever and bilateral leg pain and redness. Despite oral ciprofloxacin administration, his symptoms had not improved. The blood culture sample in the anaerobic bottle yielded positive results and was identified by mass spectrometry. The bacteremia did not initially respond to oral azithromycin but responded to intravenous meropenem and amikacin for five days followed by oral minocycline. This report indicates that bacteremia may be treated with oral minocycline following short-term intravenous antimicrobial therapy even among patients undergoing hematological malignancies.

The acute scrotum is defined as a new-onset pain of the intrascrotal contents. The differential diagnosis of acute scrotum includes a variety of etiologies. We report a case of an 18 years old presented with acute scrotal pain with scrotal ultrasound suggestive of testicular torsion, underwent bilateral orchiopexy for suspected testicular torsion. The patient came later with persistent testicular pain. A computerized tomography (CT) scan of the abdomen and pelvis was done and showed a retroperitoneal mass. We suggest that patients with atypical presentation of the acute scrotum should undergo CT scan of the abdomen and pelvis to rule out retroperitoneal pathologies and referred pain.

Recurring chest pain and other cardiac symptoms that cannot be adequately explained by organic pathology are common and can be associated with substantial disability, distress and high healthcare costs. Common mental disorders such as depression and anxiety frequently co-occur with these symptoms and, in some cases, account for their presentation, although they are not universally present. Due to the frequency of functional cardiac presentations and risks of iatrogenic harm, physicians should be familiar with strategies to identify, assess and communicate with patients about these symptoms. A systematic and multidisciplinary approach to diagnosis and management is often needed. Health beliefs, concerns and any associated behaviours should be elicited and addressed throughout. Psychiatric comorbidities should be concurrently identified and treated. For those with persistent symptoms, psychosocial outcomes can be poor, highlighting the need for further research and investment in diagnostic and therapeutic approaches and multidisciplinary service models.

This study prospectively compared intraoperative pain scores during percutaneous microwave ablation of the liver in patients randomized between continuous and pulsed energy delivery algorithms.

Lumbar disc herniation (LDH) is a common cause of radicular pain, but the mechanism is not clear. In this study, we investigated the engagement of toll-like receptor 4 (TLR4) and the nuclear factor-kappa B (NF-κB) in radicular pain and its possible mechanisms.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a debilitating multi-systemic chronic condition of unknown aetiology classified as an immune dysfunction syndrome and neurological disorder. The discovery of the widely expressed Transient Receptor Potential Melastatin 3 (TRPM3) as a nociceptor channel substantially targeted by certain opioid receptors, and its implication in calcium (Ca)-dependent Natural Killer (NK) cell immune functions has raised the possibility that TRPM3 may be pharmacologically targeted to treat characteristic symptoms of ME/CFS. Naltrexone hydrochloride (NTX) acts as an antagonist to the mu (μ)-opioid receptor thus negating its inhibitory function on TRPM3. Based on the benefits reported by patients on their symptoms, low dose NTX (LDN, 3.0-5.0 mg/day) treatment seems to offer some potential benefit suggesting that its effect may be targeted towards the pathomechanism of ME/CFS. As there is no literature confirming the efficacy of LDN for ME/CFS patients , this study investigates the potential therapeutic effect of LDN in ME/CFS patients. TRPM3 ion channel activity was measured after modulation with Pregnenolone sulfate (PregS) and ononetin in NK cells on 9 ME/CFS patients taking LDN and 9 age- and sex-matched healthy controls using whole-cell patch-clamp technique. We report that ME/CFS patients taking LDN have restored TRPM3-like ionic currents in NK cells. Small ionic currents with a typical TRPM3-like outward rectification were measured after application of PregS, a TRPM3-agonist, in NK cells from patients taking LDN. Additionally, PregS-evoked ionic currents through TRPM3 were significantly modulated by ononetin, a TRPM3-antagonist, in NK cells from ME/CFS patients taking LDN. These data support the hypothesis that LDN may have potential as a treatment for ME/CFS by characterising the underlying regulatory mechanisms of LDN treatment involving TRPM3 and opioid receptors in NK cells. Finally, this study may serve for the repurpose of marketed drugs, as well as support the approval of prospective randomized clinical studies on the role and dose of NTX in treating ME/CFS patients.

This study aimed to identify acute changes in biceps and supraspinatus tendon characteristics before and after a graded exercise test to exhaustion (GXT) in highly trained wheelchair rugby (WR) athletes. A secondary aspect was to define chronic tendon adaptations related to the impairment of the athlete and the occupation of the tendon within the subacromial space (occupation ratio).

This report describes methodological and exploratory investigations of the zymosan-induced neonatal bladder inflammation (NBI) model of interstitial cystitis/bladder pain syndrome (IC/BPS) in female rats. These results validate and extend the currently employed model by evaluating critical timepoints for obtaining treatment effects and identified that a second insult as an adult including repeat intravesical zymosan, intravesical lipopolysaccharide, acute footshock stress, neuropathic nociception (facial) or somatic inflammation (hindpaw) all resulted in magnified visceromotor responses to urinary bladder distension (UBD) in rats which had experienced NBI when compared with their controls. NBI also resulted in increased tone and reactivity of pelvic floor musculature to UBD, as well as increased responsiveness to intravesical potassium chloride solutions, abnormal anxiety measures (elevated plus maze) and an increased number of submucosal petechial hemorrhages following 30 min of hydrodistension of the bladder. These phenotypic findings have correlates to the clinical features of IC/BPS in humans and so support use of this model system to examine mechanisms of and treatments for IC/BPS.

Diabetic neuropathy is characterized by the paradoxical co-existence of hypo- and hyperalgesia to sensory stimuli. The literature shows consistently sensory differences between healthy and participants with diabetes. We hypothesized that due to differences in pathophysiology, advanced quantitative sensory testing (QST) might reveal sensory discrepancies between type 1 (T1D) and type 2 diabetes (T2D). Furthermore, we investigated whether vibration detection thresholds (VDT) were associated with sensory response. Fifty-six adults with T1D [43 years (28-58)], 99 adults with T2D [65 years (57-71)], and 122 healthy individuals [51 years (34-64)] were included. VDT, pressure pain detection thresholds (pPDT) and tolerance (pPTT), tonic cold pain (hand-immersion in iced water), and central pain mechanisms (temporal summation and conditioned pain modulation) were tested and compared between T1D and T2D. VDT was categorized into normal (< 18 V), intermediary (18-25 V), or high (> 25 V). In comparison to healthy, analysis adjusted for age, BMI, and gender revealed hypoalgesia to tibial (pPDT): = 0.01, hyperalgesia to tonic cold pain: < 0.01, and diminished temporal summation (arm: < 0.01; abdomen: < 0.01). In comparison to participants with T2D, participants with T1D were hypoalgesic to tibial pPDT: < 0.01 and pPTT: < 0.01, and lower VDT: = 0.02. VDT was not associated with QST responses. Participants with T1D were more hypoalgesic to bone pPDT and pPTT independent of lower VDT, indicating neuronal health toward normalization. Improved understanding of differentiated sensory profiles in T1D and T2D may identify improved clinical endpoints in future trials.

Intravenous infusion of lidocaine (IVF-Lido) during the perioperative period is an option to accelerate bowel function recovery after major colorectal surgery. However, previous meta-analyses have shown inconsistent conclusions. Recent randomized controlled trials (RCTs) have been reported after the publication of a previous meta-analysis.
