The heartwood of Syringa oblata Lindl. (SO) is one of Mongolian folk medicine to treat insomnia and pain, but related pharmacological evaluation and mechanism of action remains unclear. In the present study, the locomotor activity test and the threshold dose of pentobarbital sodium induced sleep test in mice were used to evaluate the sedative effect of ethanol extract of SO (ESO), and the hot plate test, acetic acid-induced writhing test and formalin test in mice were to evaluate the analgesic effect. The underlying mechanism of ESO analgesia was explored by RT-PCR and western blot analysis that associated with the regulation of NF-κB signaling pathway. Besides, the main constituents of ESO were characterized by LC-MS data analysis and comparison with isolated pure compounds. The current findings brought evidence for clinical application and further pharmacological and phytochemical studies on SO.

The use of cell technologies, in particular the stromal-vascular fraction of adipose tissue, is a new direction in the treatment of osteoarthritis of the weight-bearing joints. Stromal-vascular fraction cells have anti-inflammatory and immunomodulatory effects and are able to differentiate into connective tissue cells, including cartilage, tendons, and ligaments. Our clinical study showed the safety and good tolerability of intra-articular administration of autologous stromal-vascular fraction cells in 16 patients with severe manifestations of osteoarthritis. Single administration of stromal-vascular fraction cells led to more pronounced and stable (up to 12 months) clinical improvement in the main symptoms of the disease, including pain and functional activity of the affected joints, in comparison with intra-articular injection of hyaluronic acid (10 patients of the comparison group).

Costoclavicular brachial plexus block has been described recently as a new technique in adults and pediatric patients. In this study, we aimed to compare the supraclavicular and costoclavicular approaches, which are claimed to be effective and practical in pediatric patients.

Aim To describe results of spinal cord stimulation technique when the conventional multidisciplinary treatment of neuropathic or mixed pain failed. Methods The research was conducted at the Institute for Physical Medicine and Rehabilitation "Dr. Miroslav Zotović", Banjaluka. Ten patients, who had chronic pain resistant to other therapeutic options and a failed back surgery, were sent for an evaluation. Each patient underwent a 4-week evaluation by a team of medical specialists, phychologist and social workers. Additional diagnostic methods (MRI of the lumbosacral spine, electromyoneurography of lower extermities, congnitive assessment tests) were also performed to establish a proper indication for implantation of the system for spinal cord stimulation. Leads of a system for spinal cord stimulation were implanted percutaneously or surgically at the epidural space. Functional outcome measures (visual analogue scale, Oswestry index, anxiety and depression scales) were taken before the implantation of the system and on several followups. Results Four patients did not meet critea for the inclusion in the study (two were not ready, two showed psychopathological symptoms). One patient had a percutaneous lead implant, but it was removed after six months due to paresthesia. The remaining five had surgicaly implanted epidural leads and showed significant improvement in pain control, Oswestry index had lower values, and all except one patient had improvement registered by anxiety and depression scales. Conclusion. Short-term and long-term follow up showed a long lasting pain reduction and improvement of functionality in all patients.

Reverse total shoulder arthroplasty (RTSA) can decrease shoulder pain and improve function. However, results reportedly deteriorate as patients approach mid-term follow-up and little is known about how this impacts physical health-related quality of life (PHRQOL) and mental health-related quality of life (MHRQOL). The study hypothesis was that shoulder function, pain, and medication use for pain would influence PHRQOL and MHRQOL.

The effectiveness of onabotulinumtoxinA (BTX-A) has been established in primary trigeminal neuralgia (TN). However, to the best of our knowledge, the efficacy of BTX-A in secondary TN has not yet been studied.

Ehlers-Danlos syndromes are hereditary disorders of connective tissue that are characterized by joint hypermobility, skin hyperextensibility and tissue fragility. The most common subtype is the hypermobile type. In addition to symptoms of small fibre neuropathy (SFN) due to damage to the small peripheral nerve fibres with degeneration of the distal nerve endings, autonomic disorders such as postural tachycardia syndrome are frequently reported features in patients with hypermobile Ehlers-Danlos syndromes (hEDS). To date, the underlying pathophysiological mechanisms are still not completely understood.

We investigated the effect of an extended denervation procedure in the thumb carpometacarpal (CMC) joint in patients suffering from CMC osteoarthritis. Between 2006 and 2018, 46 patients underwent the procedure in our clinic and were included in this retrospective study. Pain, strength, range of motion, DASH score, complications and overall satisfaction were determined. Assessment showed a significant decrease in pain and excellent physical function at a median 5 years' follow-up. Twelve patients needed secondary surgery due to persistent pain. Overall, 28 of the 46 patients were satisfied with the results of the denervation. Even though the results of CMC denervation are poorer than with simple trapeziectomy, considerable pain relief can be achieved in selected young, physically active patients by exclusively soft-tissue surgery, conserving the biomechanical properties of the joint. In case of failure of the procedure, all other options remain available.

Aim To report a novel surgical technique of capsular reconstruction of post-traumatic instability of the first metatarsophalangeal joint (MTPJ). Methods The clinical case is related to a 24-year-old male athlete whose clinical symptoms began with pain and spontaneous dislocation of the left first MTPJ during a kickboxing fight. He received conservative treatment (cryotherapy and rest) at first. Afterwards, he referred persistent hallux instability associated with moderate pain, despite normal anatomic alignment with no evidence of first ray deformity. Plain traditional x-rays of the left foot, magnetic resonance imaging (MRI), static and dynamic ultrasonography (US) and clinical tests were performed in order to diagnose capsular ligamentous structure lesions. Results The plain x-rays showed angle of 3°. The MRI and US demonstrated a rupture of the lateral capsular ligamentous structures and detachment of the abductor tendon. The pull out medium-lateral of the capsule with the abductor suture was performed as a treatment for dynamic hallux varus deformity. At six-month follow up, the patient walked without lameness with complete active and passive range of motion and with a stable first MTPJ. Conclusion The patient presented with the post traumatic instability of the first metatarsophalangeal joint treated with a novel surgical technique of capsular reconstruction. The patient returned to the full weight-bearing in only 2 months of rehab. To the best of our knowledge, the surgical correction proposed has not been previously described.

Various mouse and rat models of neuropathic pain after nerve injury exist. Whilst some models involve a proximal nerve lesion or ligation of the sciatic trifurcation in mice and rats, others consists of a transection or ligation of distal nerves at the tibial bifurcation in mice or rats. The level of nerve cut directly affects the magnitude of hypersensitivity, and anatomical differences between mice and rats might therefore impact the development of hypersensitivity after distal tibial nerve transection as well.
