BACKGROUND: The precise knowledge of anatomy and the region of transverse process (TP) and superior articular processes (AP) and their distance from the skin are important in blocking and treating lumbar facet syndrome. Evaluation of these anatomic distances from 3rd and 5th lumbar vertebrae in both sides and in different body mass index (BMI) in healthy volunteers might improve knowledge of ultrasound (US) lumbar medial branch nerve blocks (LMBB). METHODS: Bilateral US in the 3rd and 5th lumbar vertebrae of 64 volunteers carried out and the distance between skin to TP and skin to AP was measured. These distances were compared on both sides and in different BMI groups. The analysis was done using SPSS 11. Analysis of variance was used to compare the means at three vertebral levels (L3-L5) and different BMI groups. P values less than 0.05 were considered statistically significant. The paired t-test was used to compare the mean distance between skin to TP and skin to AP on both sides. RESULTS: The distance between skin to TP and skin to AP of 3rd vertebrae to 5th vertebrae was increased in both right and left sides (P < 0.001) from up to down. The mean distance from skin to TP were greater on the left side compared to the right in all three vertebral levels from L3 to L5 (P values 0.014, 0.024, and 0.006 respectively). The mean distance from skin to TP and the skin to AP was statistically significant in different BMI groups (P < 0.001). CONCLUSIONS: We found many anatomic distances which may increase awareness of US guided LMBB.

BACKGROUND: Incisional pain is particularly troublesome after hysterectomy. A method called transversus abdominis plane block (TAPB) has shown promise in managing postoperative pain. In this study, we evaluated the analgesic efficacy of ultrasound-guided TAPB after hysterectomy at different time points and at each time point separately for 48 hours. METHODS: Forty-two patients (ASA I, II) who were electively chosen to undergo total abdominal hysterectomy were divided into 2 groups, control (group C) and intervention (group I). Twenty-one patients underwent TAPB (group I) and 21 patients received only the standard treatment with a fentanyl pump (group C). Both groups received standard general anesthesia. For patients in group I, following the surgery and before emergence from anesthesia, 0.5 mg/kg of ropivacaine 0.2% (about 20 cc) was injected bilaterally between the internal oblique and transverse abdominis muscles using sonography. Pain scores using the Visual Analogue Scale (VAS) and drug consumption were measured at 2, 6, 12, 24, and 48 hours after TAPB. RESULTS: There were no significant differences in demographics between the two groups. VAS scores appeared to be lower in group I, although there was no interaction with time when we compared mean VAS measurements at different time points between group I and group C (P > 0.05). The amount of fentanyl flow was consistently higher in group C, but when we compared the two groups at each time point separately, the observed difference was not statistically significant (P < 0.053). The incidence of vomiting was 10% in group I and 28% in group C. There were no complaints of itching, and sedation score was 0 to 3. There were no complications. CONCLUSIONS: This study showed that TAPB did not result in a statistically significant decrease in VAS scores at different time points. TAPB did lead to decreased fentanyl flow, but when we compared the two groups at each time point separately, the observed difference was not statistically significant.

A 57-year-old male patient had myeloma. He had severe pain in the left clavicle that did not respond to radiotherapy; therefore, it was treated with radiofrequency thermal ablation (RFTA). Under fluoroscopic guidance, two RF needles at a distance of 1.5 cm from each other were inserted into the mass and conventional radiofrequency (90degrees C and 60 seconds) at two different depths (1 cm apart) was applied. Then, 2 ml of 0.5% ropivacaine along with triamcinolone 40 mg was injected in each needle. The visual analogue pain score (VAS from 0 to 10) was decreased from 8 to 0. In the next 3 months of follow-up, the patient was very satisfied with the procedure and the mass gradually became smaller. There were no complications. This study shows that RFTA could be a useful method for pain management in painful osteolytic myeloma lesions in the clavicle.

BACKGROUND: Regional anesthesia is known to significantly impair thermoregulation and predispose patients to hypothermia. We hypothesized that the addition of an intrathecal injection of magnesium sulfate (MgSO4) to bupivacaine would improve perioperative shivering in female patients undergoing elective caesarean section. METHODS: In a block-randomized, double-blinded, controlled trial 72 patients scheduled for elective caesarean section with spinal anesthesia were separated into two groups. In the treatment group, 2 ml of 0.5% bupivacaine plus 25 mg MgSO4 (0.5 ml) were injected intrathecally, and in the control group 2 ml of 0.5% bupivacaine plus 0.5 ml normal saline were injected intrathecally. Core temperature was measured before and after drug injection at predetermined intervals. Sedation was graded using the Ramsay sedation scale. RESULTS: No significant intergroup differences in appearance of shivering were seen immediately or at 5, 30, 40, 50, 60, and 90 min after block administration. However, at 10, 15, and 20 min post block, there was a significant difference in shivering. The group administered MgSO4 showed lower shivering grades compared with the control group. Core temperature was significantly reduced in the MgSO4 group compared to the normal saline group 30 min after blocking. CONCLUSIONS: Intrathecal injection of MgSO4 improved perioperative shivering in female patients undergoing elective caesarean section.

BACKGROUND: The pes anserine bursa lies beneath the pes anserine tendon, which is the insertional tendon of the sartorius, gracilis, and semitendinosus muscles on the medial side of the tibia, but it can lie in different sites in the medial knee. Accurate diagnosis of the position of the bursa is critical for diagnostic and therapeutic goals. The aim of this study was to evaluate sonoanatomic variations of the pes anserine bursa in the medial knee. METHODS: One hundred seventy asymptomatic volunteers were enrolled in this study. Using ultrasound imaging (transverse approach, 7-13 MHz linear array probe) the sonoanatomic position of the pes anserine bursa and its relation to the pes anserine tendon were evaluated. Additionally, we evaluated the sonoanatomic variation of the saphenous nerve. RESULTS: The position of the pes anserine bursa was between the medial collateral ligament and the pes anserine tendons in 21.2%/18.8% (males/females) of subjects; between the pes anserine tendons and the tibia in 67.1%/64.7% (m/f); and among the pes anserine tendons in 8.2%/12.9% (m/f). No significant differences in the position of the bursa existed between males and females. The saphenous nerve was found within the pes anserine tendons in 77.6%/74.1% (m/f) of subjects, but outside the pes anserine tendons in 18.8%/15.3% (m/f). Visibility of sonoanatomic structures was not related to either gender or BMI. CONCLUSIONS: Ultrasound provides very accurate information about variations in the pes anserine bursa and the saphenous nerve. This suggests that our proposed ultrasound method can be a reliable guide to facilitate approaches to the medial knee for diagnostic and therapeutic objectives.

Background: Fecal incontinence (FI) results from damage to the external anal sphincter (EAS), significantly affecting quality of life. This clinical trial evaluated the impact of low-level laser (LLL) therapy on EAS repair and the treatment of FI. Methods: Thirty FI patients with EAS deficiency were divided into two groups (n = 15): a control group receiving sphincteroplasty alone and a laser group undergoing sphincteroplasty plus laser therapy. Following surgery, the laser group received daily laser therapy for 2 weeks. Outcomes were assessed using Wexner scores, electromyography (EMG), and endorectal sonography. Results: The laser group exhibited a significant increase in muscle bulk (P = 0.008) and a lower Wexner index (P < 0.0001) compared to the control group. EMG confirmed muscle contractility in the laser group. Conclusions Two weeks of LLL therapy effectively increased muscle at the EAS injury site, leading to significant, lasting improvements in FI.
