A primigravida presented to our institution in established labour. Her past medical history included joint hypermobility, postural orthostatic tachycardia syndrome, Raynaud's syndrome, fibromyalgia and gastroparesis. Two technically uneventful lumbar epidurals with bupivacaine and fentanyl provided no analgesia. The spinal element of a planned combined spinal and epidural was also ineffective, so alternative analgesia was offered. While this was being prepared, the obstetric team recommended an instrumental delivery. An attempted pudendal nerve block with lidocaine had no effect, and general anaesthesia was therefore provided for a lower segment caesarean delivery. We believe this is the first report of local anaesthetic resistance via three distinct routes of administration in a single patient. Resistance to local anaesthetics is unusual and is more common in patients with hypermobility spectrum disorders. This case demonstrates the unique experience of a patient with a hypermobility condition who had failed epidural, spinal and pudendal local anaesthetic. We suggest that patients with a hypermobility condition should be specifically assessed for local anaesthetic resistance as part of anaesthetic pre-assessment, to enable early planning.

After periodontal surgery, in most cases, the surgical area is covered with a surgical pack. It has been suggested that these packs might minimize complications. This study aimed to compare the effects of Diplen LX membrane and Coe-Pak on pain, wound healing, and patient preference after a periodontal flap surgery in patients with moderate to severe chronic periodontitis. In this randomized clinical trial, 26 patients were evaluated. Pain scores were assessed using visual analog scale (VAS) on the 3rd and 7th days postoperatively and compared between the two dressings. On the 7th and 14th days after both flap surgeries, surgical site healing was evaluated using the wound healing index (WHI). The mean age of the patients was 31. It was observed that the severity of pain in the studied patients on the 3rd and 7th days postoperatively was significantly lower in the intervention group than in the control group. It was also observed that the value of WHI in the studied patients on the 7th and 14th days postoperatively was significantly higher in the intervention group than in the control group. The pain was less severe in both groups using periodontal dressing and also lower in the Diplen LX membrane group. In addition, based on WHI, wound healing score in patients was also higher and more favorable in the Diplex LX membrane group. Due to the above factors, the majority of patients preferred the use of the Diplen LX membrane.

Chronic low back pain (cLBP) is a complex with a heterogenous clinical presentation. A better understanding of the factors that contribute to cLBP is needed for accurate diagnosis, optimal treatment, and identification of mechanistic targets for new therapies. The Back Pain Consortium (BACPAC) Research Program provides a unique opportunity in this regard as it will generate large clinical datasets including a diverse set of harmonized measurements. The Theoretical Model Working Group (TMWG) was established to guide BACPAC research, and to organize new knowledge within a mechanistic framework. This article summarizes the initial works of the TMWG. It includes a three-stage integration of expert opinion and an umbrella literature review of factors that affect cLBP severity and chronicity. During Stage 1, experts from across BACPAC established a taxonomy for risk and prognostic factors (RPFs) and preliminary graphical depictions. During Stage 2, a separate team conducted a literature review according to PRISMA guidelines to establish working definitions, associated data elements (ADEs), and overall strength-of-evidence (SOE) for identified RPFs. These were subsequently integrated with expert opinion during Stage 3. The majority (∼80%) of RPFs had little SOE confidence, while 7 factors had substantial confidence for either a positive association (pain-related anxiety, serum c-reactive protein, diabetes, and anticipatory/compensatory postural adjustments) or no association (serum interleukin 1-beta/interleukin 6, transversus muscle morphology/activity, and quantitative sensory testing) with cLBP. This theoretical perspective will evolve over time as BACPAC investigators link empirical results to theory, challenge current ideas of the biopsychosocial model, and utilize a systems approach to develop tools and algorithms that disentangle the dynamic interactions between cLBP factors.

A 27-year-old Nepalese male presented with recurrent abdominal pain accompanied by a lower stool consistency over the past 2 years. These episodes occurred several times a year, lasting 1 to 2 weeks, and resolved spontaneously, after adjustment of diet and/or medication for symptomatic control (e.g., antispasmodics, probiotics). Over the last year, the patient had undergone an extensive diagnostic investigation, which revealed no alterations in the laboratory workup, abdominal scan, esophagogastroduodenoscopy, and colonoscopy, including biopsies of the duodenum, and colon, so the symptoms have been attributed to irritable bowel syndrome. However, the symptoms had become more frequent, so the patient was referred to our gastroenterology department. We repeated and extended the work-up. Laboratory investigations showed an elevated erythrocyte sedimentation rate and faecal calprotectin. The remaining laboratory as well an extensive stool workup for infection were unremarkable. Esophagogastroduodenoscopy and ileocolonoscopy were normal. Small bowel capsule endoscopy revealed jejunal mucosa with lymphangiectasias, pseudopolypoids formations and superficial longitudinal ulcers, these findings were corroborated by the double-balloon enteroscopy, and biopsies showed marked architectural distortion, chronic inflammatory infiltrate, and an epithelioid granuloma. The clinical, endoscopic, biochemical, and histological findings were consistent with isolated jejunal Crohn's disease. The patient started adalimumab with complete remission after one year. We present this case given its exuberant endoscopic findings and due to the difficulty in making the diagnosis due to its rarity, location, and unspecific presentation.

We describe the case of a 69-year-old male with Crohn's disease (CD), treated with infliximab and undergoing intestinal resection. The surgery and postoperative period were unremarkable, with no CD-related symptoms. Two months after surgery and two weeks after the introduction of infliximab, he was admitted due to acute onset diffuse abdominal pain, hematochezia and arthralgia. On physical observation on admission, he showed signs of arthritis of the left knee. Laboratory tests revealed renal failure with nephrotic proteinuria, slightly low complement (C3) and IgA elevation. Remaining autoimmunity and viral panel were negative. Abdominal examination showed duodenum and thickening of the proximal wall of the jejunum. Biopsies excluded active CD. Colon and ileum mucosa were normal. The patient met EULAR criteria for Henoch-Schönlein purpura and was started on prednisolone with response. Although no clear trigger was pointed out, we switched anti-TNF to ustekinumab. We present this case given its endoscopic exuberance, and because of the high index of suspicion to make the diagnosis in adult patients with previous inflammatory bowel disease. The distinction between this vasculitis and CD is of utmost importance, given the therapeutic implications.

The numerous drugs in the NSAID class are often used to treat acute postoperative pain associated with oral surgery such as impacted third-molar extractions. These drugs are effective in this setting and dental pain studies often serve as models for acute pain relief and for registration of analgesics. With numerous cyclooxygenase (COX) inhibitors available as monotherapy, for use in combination analgesic regimens, and in different doses and formulations, it was our aim to determine if there were clear-cut distinctions among these products and dosing regimens.

This study aims to examine age differences in the intensity of chronic pain among middle-aged and older adults, where intensity is measured on a scale differentiating between chronic pain that is often troubling and likely requires intervention versus more endurable sensations. We aim to explore whether individual health and national gross domestic product (GDP) explain these differences as well.

Puumala hantavirus (PUUV) causes most cases of haemorrhagic fever with renal syndrome (HFRS) in Europe. PUUV infection is characterised by acute kidney injury, thrombocytopenia and increased capillary leakage. Typical symptoms are fever, headache, nausea, abdominal and back pain. This study aimed to evaluate the amount and distribution of intraperitoneal, retroperitoneal and pleural fluid and the association of fluid collections to the symptoms and clinical findings in patients with acute PUUV infection.

Although several studies have investigated effective treatments for masticatory muscle pain (MMP), no unified conclusion has been drawn regarding the effectiveness of these treatments.
