A Comparative Analysis of Erector Spinae Plane Block Versus Conscious Sedation in Managing Percutaneous Cholecystostomy Pain.

PURPOSE: This study investigates the efficacy of erector spinae plane block (ESPB) for managing perioperative and postoperative pain in patients undergoing percutaneous cholecystostomy (PC) for acute cholecystitis, particularly in high-risk elderly patients with extensive comorbidities and limited functional status. METHODS: In a retrospective single-center study, 58 high-risk patients scheduled for PC were assessed. ESPB was administered to 23 patients, while 22 received conscious sedation. Pain intensity was measured using the numeric rating scale before any analgesic or ESPB administration, during the procedure and at 1 and 12 h post-procedure and secondary outcomes included adverse effects and additional analgesic requirements. RESULTS: The ESPB group experienced significant pain reduction during and post-procedure compared to the conscious sedation group (p = 0.002). Procedure times were shorter (p = 0.015), and postoperative tramadol was less frequently needed in the ESPB group (p = 0.007). The incidence of nausea was also lower in the ESPB group (p = 0.001). No ESPB-related complications were reported. CONCLUSION: ESPB significantly alleviates perioperative and postoperative pain in PC patients, reducing additional analgesic use and side effects. It holds promise as a key component of pain management for high-risk surgical patients. LEVEL OF EVIDENCE: Level 3, Non-randomized controlled cohort/follow-up study.

Percutaneous CT-Guided Microwave Ablation for the Treatment of Osteoid Osteomas: A Single Center Experience.

RATIONALE AND OBJECTIVES: The aim of the current study was to evaluate the feasibility and effectiveness of CT-guided microwave ablation (MWA) in the treatment of osteoid osteomas (OO). MATERIALS AND METHODS: Data from 59 consecutive patients who underwent percutaneous CT-MWA for OO treatment were examined in the current retrospective study. The period of this study spanned from January 2021 to May 2023 at a single institution. The study involved an evaluation of clinical and radiological characteristics, procedural data, Visual Analog Scale (VAS) pain scores, complication incidences, as well as clinical and technical success rates. Statistical analyses were performed by using the Wilcoxon test with Bonferroni correction, Friedman, Spearman, Mann-Whitney U test. RESULTS: 59 patients with an average age of 17.31 ± 8.53 years underwent CT-guided MWA for the treatment of OO. The procedure demonstrated a high success rate, with 96.6% of cases achieving both technical and clinical success. However, recurrence was observed in two patients (3.4%) at the three-month follow-up. These cases were successfully managed with a second MWA procedure. The median VAS pain scores reported by the patients was significantly improved post-procedure: from 8.64 ± 1.14 before treatment to 0.63 ± 0.98 in the first month, 0.41 ± 1.02 in the third month, and 0.15 ± 0.45 in the sixth month. Only one patient (1.7%) experienced a minor complication; no major complications were recorded in this study. CONCLUSION: CT-guided percutaneous MWA is a minimally invasive and a highly effective and safe approach for the treatment of OO.

The predictive value of systemic inflammatory markers in 902 patients with tunneled hemodialysis catheter.

AIM: This study aimed to assess the predictive role of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and mean platelet volume, on catheter survival in chronic hemodialysis patients, analyzing both infectious and non-infectious complications. METHODS: A retrospective analysis encompassed 1279 tunneled catheter insertion procedures involving 902 patients between March 2014 and October 2018. Patients were categorized into two main groups: (i) initial placement and (ii) exchange. The exchange group was further stratified into four subgroups: infection, dysfunction, displacement, and transitioning temporary hemodialysis catheters to long-term ones. Hematologic ratios were calculated from baseline hemogram data, including neutrophil, lymphocyte, monocyte, and platelet counts, while mean platelet volume was derived from the same hemogram. RESULTS: The patients in the exchange group displayed significantly higher lymphocyte and monocyte values (p < 0.001), while lower values were noted for neutrophil-lymphocyte ratio and platelet-lymphocyte ratio (p < 0.001). The transition group displayed higher monocyte values and lower mean platelet volume and lymphocyte-monocyte ratio values (p < 0.05). In the infection-related exchange subgroup, higher neutrophil count, mean platelet volume, neutrophil-lymphocyte ratio, and platelet-lymphocyte ratio values were observed compared to other groups (p < 0.05). Cases related to catheter dysfunction exhibited increased lymphocyte-monocyte ratio but lower neutrophil, monocyte, neutrophil-lymphocyte ratio, and platelet-lymphocyte ratio values (p < 0.05). CONCLUSION: This study highlights the interest of specific inflammatory markers, particularly monocytes, neutrophil-lymphocyte ratio, and platelet-lymphocyte ratio, in the management of tunneled catheters, notably in patients undergoing exchanges. However, cut-off values, essential for constructing management algorithms, are currently lacking, and prospective multicenter studies are needed for further elucidation.

Successful treatment of a rheumatoid arthritis patient with severe synovial hypertrophy and impaired shoulder function with microwave ablation technique.

Rheumatoid arthritis (RA) is a chronic, inflammatory systemic disorder of synovial joints and results in polyarthritis, chronical degeneration, and finally deformities and ankylosis in severe cases. Synovitis and pannus formation are results of inflammatory changes and lead into restriction in joint movement. Shoulders are among the later affected and larger joints and formation of synovitis in early active stages and pannus in later stages might be concluded with frozen shoulder and severe impairment in functionality. These late-term changes cannot be controlled with systemic or local anti-inflammatory agents and synovectomy is chosen in some cases. However, the results are not satisfactory and recurrence is common. In this case report, we presented a case of RA with severe shoulder pain, restricted movement due to synovial hypertrophy, and pannus formation which are resistant to local and systemic interventions and not suitable for surgical or chemical synovectomy. Microwave ablation (MWA) was performed successfully without any complication and she well responded in terms of DAS-28, functional, and pain scores. Range of motion and funcitonal restriction were recovered. This case report describes the use and promising results of MWA in RA with severe synovial hypertrophy and pannus formation even in the absence of active arthritis and effusion. MWA is a safe and minimally invasive technique that can be easily performed in coordinance of rheumatologists and interventional radiologists in proper cases.

Effectiveness of polidocanol sclerotherapy in alleviating symptoms in patients with venous malformations.

OBJECTIVE: The objective of this study was to retrospectively evaluate the effectiveness of polidocanol in managing pain, swelling, functional limiting and cosmetic disorders in patients with venous malformations (VMs). METHODS: This retrospective study included patients who underwent sclerotherapy with polidocanol for VMs between 2020 and 2022. Patient records, imaging findings, and evaluation questionnaires used in the preprocedure and follow-up phases were reviewed. After sclerotherapy, patients were followed up at 1, 2, 3, and 6 months. During these visits, the previously used 11-point verbal numerical rating scale (from 0 [no pain] to 10 [worst pain thinkable]) was used to evaluate the severity of symptoms such as pain, swelling, cosmetic discomfort, and functional limitation, and patients were asked to report the number of days per week they experienced these symptoms owing to the VM. RESULTS: A total of 194 sclerotherapy procedures (mean, 1.6 ± 0.3 procedures) in 84 patients (55 female and 29 male patients; mean age, 22.45 ± 11.83 years) were conducted. The majority of these malformations (81%, or 68 patients) were located in the extremities. We found a significant decrease in pain, swelling, functional limitation, cosmetic appearance, and number of painful days between all time points, except for the comparison between months 3 and 6 (P < .001) CONCLUSIONS: Polidocanol sclerotherapy is a safe and effective treatment for VMs that significantly decreases patient complaints and has a very low complication rate. Particularly, following patients at short intervals and administering additional sclerotherapy sessions when necessary will significantly increase patient satisfaction.

68Ga-Prostate-Specific Membrane Antigen-11 PET/CT: Incidental Finding of a Vestibular Schwannoma.

A 77-year-old man with newly diagnosed prostate adenocarcinoma with a total prostate-specific antigen level of 6.4 ng/mL and Gleason score 7 (4 + 3) was referred to Ga-prostate-specific membrane antigen-11 (PSMA) PET/CT for initial staging. An intense focal PSMA uptake was shown in the right peripheral zone of the prostate gland consistent with the primary tumor. Additionally, PET/CT demonstrated a PSMA-avid soft tissue mass in the left cerebellopontine angle. The patient had a history of left-sided sensorineural hearing loss.

Regional anesthesia with epinephrine-containing lidocaine reduces pericatheter bleeding after tunneled hemodialysis catheter placement.

INTRODUCTION: Pericatheter bleeding (PB) following tunneled hemodialysis catheter (THC) placement is a common phenomenon. In addition to complicating securement of the THC, the PB may loosen the adhesive catheter dressing and delay wound healing. The primary aim of this study was to determine whether epinephrine-containing local anesthetics rather than plain ones reduce superficial PB after THC placement. METHODS: The study was based on the retrospective analysis of the prospectively gathered data. Forty-six patients receiving local analgesia during THC placement were randomly assigned in a double-blind manner to two groups according to local anesthetic mixtures used (n =22 to prilocaine group [group 1]; n =24 to epinephrine-containing lidocaine group [group 2]). Presence or absence of PB after the THC placement was evaluated. Differences between groups with and without controlling other variables were statistically analyzed. FINDINGS: Epinephrine-containing lidocaine (group 2) significantly reduced PB in comparison with prilocaine, P = 0.003. Use of epinephrine-containing lidocaine (group 2) was associated with a reduction in the likelihood of PB (Odds ratio = 0.017). Meanwhile, use of prilocaine (group 1) had 59.7 times higher odds in the likelihood of PB after THC placement. Lower rate of systolic blood pressure (SBP) in group 2 patients after 5 minutes of injections was also noted, P = 0.008. Epinephrine-containing lidocaine was well tolerated and caused no significant cardiovascular disturbance. DISCUSSION: Local infiltration of epinephrine-containing lidocaine instead of plain local anesthetics during THC insertion may reduce superficial PB and improve patient comfort.

Is anterolateral ligament rupture a reason for persistent rotational instability after anterior cruciate ligament reconstruction?

BACKGROUND: The aim of the present study was to evaluate the clinical role of anterolateral ligament (ALL) rupture and its impact on rotational stability by comparing the clinical results and rotational stability between reconstructed anterior cruciate ligament (ACL) with intact ALL knees and reconstructed ACL with ALL injured knees. METHODS: A total of 69 patients who had undergone surgery for ACL reconstruction and had received a minimum of two years of follow-up were included. Patients were divided into two groups with respect to the presence of ALL rupture on knee magnetic resonance imaging. Patients were assessed preoperatively and at final follow-up with physical examination findings and functional outcomes. Rotational stability was measured by a non-invasive rotameter-like device at the final follow-up at different torque values of 5 Nm (newton metres), 10 Nm and 15 Nm, and compared between the two groups. RESULTS: The ALL was considered to be ruptured in 45 cases, named Group I (65.2%). The ALL was considered to be intact in 24 cases, named Group II (34.8%). No significant difference was found between the groups regarding the improvement of the clinical scores and physical examination findings (P > 0.05). Group I showed significantly higher internal rotation difference compared with Group II in all torque values (P < 0.05). CONCLUSION: The difference found on rotational measurement is possibly under the value of minimal clinical important difference and does not have a clinical effect, therefore ALL reconstruction is not recommended as a standard treatment in all patients.

Angiographic Embolization in the Treatment of Puerperal Hematoma.

Puerperal hematoma is one of the life threatening obstetrical emergencies. Surgical ligation of bleeding vessel may not always be possible for the patients who were hemodynamically unstable, hence pelvic arterial angiography may be preferred as the first line treatment modality for these cases. Pelvic arterial angiography and embolization is a safe, tolerable, and minimally invasive treatment modality in the diagnosis and treatment of pelvic hemorrhage. We present a case of puerperal hematoma after a normal spontaneous delivery treated with bilateral iliac arterial embolization.

Diffusion-weighted and diffusion-tensor imaging of normal and diseased uterus.

Owing to technical advances and improvement of the software, diffusion weighted imaging and diffusion tensor imaging (DWI and DTI) greatly improved the diagnostic value of magnetic resonance imaging (MRI) of the pelvic region. These imaging sequences can exhibit important tissue contrast on the basis of random diffusion (Brownian motion) of water molecules in tissues. Quantitative measurements can be done with DWI and DTI by apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values respectively. ADC and FA values may be changed by various physiological and pathological conditions providing additional information to conventional MRI. The quantitative DWI assists significantly in the differentiation of benign and malignant lesions. It can demonstrate the microstructural architecture and celluler density of the normal and diseased uterine zones. On the other hand, DWI and DTI are useful for monitoring the treatment outcome of the uterine lesions. In this review, we discussed advantages of DWI and DTI of the normal and diseased uterus.
