Summary: The pericapsular nerve group (PENG) block is a novel regional anaesthesia technique that aims to provide hip analgesia with preservation of motor function, although evidence is currently lacking. In this single‐centre, observer‐masked, randomised controlled trial, patients undergoing total hip arthroplasty received pericapsular nerve group block or no block (control group). Primary outcome measure was maximum pain scores (0–10 numeric rating scale) measured in the first 48 h after surgery. Secondary outcomes included postoperative opioid consumption; patient mobilisation assessments; and length of hospital stay. Sixty patients were randomly allocated equally between groups. The maximum pain score of patients receiving the pericapsular nerve group block was significantly lower than in the control group at all time‐points, with a median (IQR [range]) of 2.5 (2.0–3.7 [0–7]) vs. 5.5 (5.0–7.0 [2–8]) at 12 h; 3 (2.0–4.0 [0–7]) vs. 6 (5.0–6.0 [2–8]) at 24 h; and 2.0 (2.0–4.0 [0–5]) vs. 3.0 (2.0–4.7 [0–6]) at 48 h; all p < 0.001. Moreover, the pericapsular nerve group showed a significant reduction in opioid consumption, better range of hip motion and shorter time to ambulation. Although no significant difference in hospital length of stay was detected, our results suggest improved postoperative functional recovery following total hip arthroplasty in patients who received pericapsular nerve group block.

Background: Following surgical procedures, over 80% of patients experience acute pain, with half of them expressing dissatisfaction with pain relief. The modern approach to surgical treatment and pain management increasingly relies on implementing multimodal analgesia, which includes the use of adjuvants in addition to long-acting local anesthetics (such as ropivacaine). This double-blind randomized study evaluated the analgesic effect of magnesium sulfate added to ropivacaine in the sciatic nerve block at the popliteal level for bunion correction surgery., Methods: In this double-blind study, fifty patients were enrolled and randomized in a 1:1 ratio to receive ropivacaine and MgSO4 200 mg or ropivacaine and physiological solution. The primary endpoint was the duration of sensory block., Results: A statistically significant difference was observed in the onset time for sensory block (9.2 minutes vs. 21.8 minutes, P<0.001) and its duration (18.2 hours vs. 13.9 hours, P<0.001) between the two groups. Between 12 and 24 hours postoperatively, the maximum NRS pain scores in the magnesium group were lower than those in the control group (IQR [range]) 2 (2-3.8 [0-6.5]) vs. 6.7 (5.6-7.9 [2.7-9.2], P<0.001). The need for additional opioids after 12-24 hours was significantly higher in patients in the physiological solution group compared to those in the magnesium group., Conclusions: Our results suggest that magnesium added to the local anesthetic extends sensory block duration, reduces postoperative pain, improves the quality of analgesia, decreases the need for additional opioids. Further studies are needed to confirm these preliminary findings.

The GlideScope® is a videolaryngoscope manufactured by Verathon Medical (Bothell, WA, USA), now widely used to manage planned or unexpected difficult orotracheal intubation situations. According to the current literature, GlideScope® has been used for surgical procedures involving the tongue base, such as biopsies and radiofrequency treatment of obstructive sleep apnea. We describe a case of dual use of GlideScope for pointed foreign body removal in an emergency department., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Saudi Journal of Anesthesia.)

Objective: Comparison between the usefulness of immunological markers and intestinal biopsy in the diagnosis and follow-up of coeliac disease., Materials and Methods: Serum antibodies to gliadin, several dietary proteins and endomysium were appraised in 27 patients with biopsy proven coeliac disease, both while untreated and 6-8 months after gluten withdrawal, when an intestinal biopsy was repeated. Forty-six healthy volunteers entered the study as controls. Antibodies to gliadin and dietary proteins were assessed by ELISA, antibodies to endomysium by indirect immunofluorescence using monkey oesophagus as antigen., Results: Mean antibody levels to dietary proteins were significantly higher in untreated patients as compared to controls. Their titers decreased after gluten withdrawal, but a significant difference was found, except for casein, for the IgA class only. However, because of their unlinear and unpredictable behaviour, they showed a poor reliability. Antigliadin antibodies showed higher diagnostic accuracy, although they also produced false-positive and false-negative results. Anti-endomysium antibodies, albeit the more expensive, proved the more reliable, due to their 100% specificity., Conclusion: To date, anti-endomysium antibodies are the most reliable marker for coeliac disease: a positivity warrants an intestinal biopsy. The actual role of antibodies to gliadin, cheaper than endomysium, is during follow-up when many determinations are needed. Antibodies to dietary proteins, useful in the pre-endomysium era, only have a historical role.

Inflammatory mediators seem to be involved in the pathogenesis of Crohn's disease. Tumor necrosis factor is a primary mediator of inflammatory responses which causes metabolic effects related to tissue wasting. The aims of this study were to establish the presence of tumor necrosis factor in Crohn's disease patients, to determine of its serum levels reflect disease activity and to examine the relationship if this cytokine with other assessments of the activity of the disease. Serum concentration of tumor necrosis factor, measured with a biological assay, was significantly raised in 56 Crohn's disease patients (201 determinations) as compared with 44 controls (P < 0.0001). Patients with inactive disease had significantly lower tumor necrosis factor levels (3.58 +/- 0.55 ng/mL) as compared to patients with active disease (8.17 +/- 1.01 ng/mL). There was a significant correlation between serum tumor necrosis factor concentration and disease activity (r = 0.237, P < 0.002). Higher tumor necrosis factor levels were detected in patients with colonic involvement (ileocolitis and colitis) as compared with ileal localizations, and the difference was significant (t = 2.16, P < 0.05). Besides, it correlated negatively with albumin, haemoglobin and cholesterol.

The identification of anti-endomysial antibodies in the serum of coeliac patients has provided a useful diagnostic tool to be used together with biopsy. In this study the presence of these antibodies was evaluated in a population of adult coeliac patients. 92.86% sensitivity and 100% specificity were obtained together with 98.68% diagnostic accuracy. The antibody titer tends to diminish progressively and become negative in patients who adhere strictly to their diet. Anti-endomysial antibodies may therefore be used at both the screening stage as well as during follow-up and they allow an objective assessment of diet compliance to be made.
