Objectives

Body protective compound-157 (BPC-157) is a stable gastric pentadecapeptide that has been effective in trials aiming to increase wound healing capabilities and decrease inflammatory cell influx, including studies on the healing of muscles and tendons. There are no studies about the effect of BPC-157 on pain transmission via nociception. This study examined the antinociceptive effects of BPC-157 using formalin tests and immunohistochemistry.

Methods

Rats were randomly divided into the control, morphine and BPC-157 groups. Pain behavior was quantified periodically at 5- and 35- min intervals (representative values of phases 1 and 2) by counting the number of flinches exhibited by the injected paw after injection. The dorsal root ganglia (DRG) and spinal cords (SC) were collected, and then, the number of cytokine-positive cells was determined via immunostaining.

Results

BPC-157 dose-dependently decreased the number of flinches during phase 1 but did not decrease the number of flinches during phase 2. During phase 1, interleukin-1β (IL-1β) in the DRG tissue was significantly different in the morphine, 10 μg/kg BPC-157, and 20 μg/kg BPC-157 groups. During phase 2, statistical significance was achieved in the DRG tissue in the morphine, 20 μg/kg BPC-157, and 40 μg/kg BPC-157 groups. During phase 1, interleukin-6 was significantly different in the DRG tissue in the morphine group and the SC tissue in the 10 μg/kg BPC-157 group. During phase 2, statistical significance was achieved in the morphine group and the BPC-157 20 μg/kg group in both the DRG and SC tissues. There were no significant differences in tumor necrosis factor-α between the DRG and SC tissues.

Conclusions

BPC-157 was effective during phase 1 but not during phase 2, as determined by the formalin test. BPC-157 decreased the expression of IL-1β in the DRG tissue in phases 1 and 2.

Tracheostomy is increasingly performed in children for upper airway anomalies. Here, an 18-month-old child (height 84.1 cm, weight 12.5 kg) presented to the emergency department with dyspnea, stridor, and chest retraction. However, exploration of the airways using a bronchoscope failed due to subglottic stenosis. Therefore, a surgical tracheostomy was successfully performed with manual mask ventilation. However, pneumomediastinum was found in the postoperative chest radiograph. Although an oxygen saturation of 99% was initially maintained, oxygen saturation levels dropped, due to sudden dyspnea, after 3 hours. A chest radiograph taken at this time revealed a left tension pneumothorax and small right pneumothorax. Despite a needle thoracostomy, the pneumothorax was aggravated, and cardiac arrest occurred. Cardiopulmonary-cerebral resuscitation was performed, but the patient was declared dead 30 minutes later. This study highlights the fatal complications that can occur in children during tracheostomy. Therefore, close monitoring, immediate suspicion, recognition, and aggressive management may avoid fatal outcomes.

In this case report, we describe the use of ultrasound in the administration regional anesthesia for a super-super obese patient. A 23-year-old female patient (height 167.2 cm, weight 191.5 kg, body mass index 68.6 kg/m2) was admitted to the hospital for surgical repair of an anterior talofibular ligament rupture. We used ultrasound to help facilitate the administration of regional anesthesia. In the sagittal view of the lumbar spine, (with the patient in a sitting position) we were able to identify the border between the sacrum and the lumbar vertebral; in the transverse view, we were able to identify the transverse process, posterior dura, vertebral body, and the distance from the skin to the posterior dura. After skin marking, regional anesthesia was successfully performed. Based on this case study, we suggest that ultrasound can be very useful in regional anesthesia for severely obese patients.

An incidentaloma is a tumor found incidentally without clinical symptoms or suspicion; the lesion may be adrenal, pituitary, or thyroidal. We report the case of an asymptomatic individual with preoperatively undiagnosed pheochromocytoma (size: 4.86 cm) that was revealed using elective nonadrenal surgical procedures. The patient demonstrated peri- and post-operative hypertensive crisis and tachycardia. Three days after the dramatic onset of symptoms, the patient expired due to pulmonary edema, multiple organ failure, and terminal sepsis, despite administration of extracorporeal membrane oxygenation-assisted cardiopulmonary resuscitation. A left medial kidney mass obtained at autopsy confirmed pheochromocytoma.

Knotting of a pulmonary artery catheter (PAC) is a rare, but well-known complication of pulmonary artery (PA) catheterization. We report a case of a double-knotted PAC with a large loop in a patient with hepatocellular carcinoma (HCC) undergoing liver transplantation, which has been rarely reported in the literature. A PAC was advanced under pressure wave form guidance. PAC insertion was repeatedly attempted and the PAC was inserted 80 cm deep even though PAC should be normally inserted 45 to 55 cm deep. However, since no wave change was observed, we began deflating and pulling the balloon. At the 30-cm mark, the PAC could no longer be pulled. Fluoroscopy confirmed knotting of the PAC after surgery (The loop-formed PAC was shown in right internal jugular vein); thus, it was removed. For safe PA catheterization, deep insertion or repeated attempts should be avoided when the catheter cannot be easily inserted into the pulmonary artery. If possible, the insertion of PACs can be performed more safely by monitoring the movement of the catheter under fluoroscopy or transesophageal echocardiography.
