Twelfth rib syndrome is thought to be due to intercostal nerve irritation by a mobile twelfth rib, and presents with upper abdominal pain, or low thoracic pain. This syndrome appears to be a fairly common entity and diagnosis is based on clinical findings. Patients with twelfth rib syndrome can be misdiagnosed when it has been overlooked. We report a case of a 34-year-old male along with a presentation of twelfth rib syndrome. One patient was transferred from urologic clinic to pain clinic due to right flank pain and admitted. The patient had direct tenderness on twelfth rib area and direct tenderness was reproducible. Pain increased when the patient flexed laterally, rotated trunk. There were no specific abnormal findings in laboratory test, electrocardiogram, and radiologic examination. After intercostal nerve block and epidural block, pain decreased and the patient was discharged.

Aim: Disc displacement without reduction of the temporomandibular joint (TMJ) has been managed by mandibular manipulation to reduce the displaced disc but with a low success rate. The purpose of this study was to determine whether auriculotemporal nerve block anesthesia had an effect on the reduction of the displaced disc and to analyze the factors that influenced the result. Methods: 112 patients were diagnosed with disc displacement without reduction and treated by mandibular manipulation. Disc was recaptured in 35 patients. Among the 77 patients with whom disc recapture had failed, the auriculotemporal nerve was blocked with a local anesthetic in the 49 patients (mean $age \;{\pm}\; SD\; =\; 34.4\;{\pm}\; 15.1$; male 24, female 25) and then mandibular manipulation was performed again. Factors including age, elapsed time from the onset, and opening amount were analyzed in association with disc reduction rate with the auriculotemporal nerve block. Results: Among 49 patients who did not respond to manipulation only, manual reduction with auriculotemporal nerve block anesthesia was successful in 19 patients (38.8%). Maximum unassisted opening amount significantly increased in the 19 patients with successful recapture of the disc ($mean \;{\pm}\; SD\; =\; 46.1 \;{\pm}\; 4.5\; mm$), in contrast to the limited opening amount of the 49 patients before local anesthesia of the auriculotemporal nerve ($mean \;{\pm}\; SD\; =\; 25.7 \;{\pm}\; 6.0\; mm$). Age, elapsed time after the onset, and preoperative opening amount were not associated with the reduction rate. Conclusion: The results of this study suggest that auriculotemporal nerve block anesthesia increases the reduction rate of the disc displacement without reduction of the TMJ when combined with mandibular manipulation, and such anesthesia should be applied at the first stage of manual treatment of disc displacement without reduction.

Purpose: The nose is the most prominent skeletal feature of the face and is thus prone to frequent injury. Closed reduction of nasal bone fractures can be performed under general or local anesthesia. However, the benefits and the drawbacks in either form of anesthesia chosen are seldom perceived by the surgeon. A retrospective study was performed to assess the differences in the outcome among the two groups subjected to surgery under different type of anesthesia and to introduce our method of local anesthesia and its adequacy. Methods: Two hundred and fifteen patients during a 2-year period were included in the study. 2% Lidocaine mixed with 1:100,000 epinephrine was injected on the anterior ethmoid nerve and the periosteum. Assessment factors included intra-operative adequacy of analgesia, post-operative analgesic requirement and functional and aesthetic outcome of surgery. Results: 19 patients were manipulated under general anesthesia and 196 patients were manipulated under local anesthesia on the anterior ethmoidal nerve and dorsal periosteum. No statistically signigicant variable in performance of surgery could be attributed to the mode of anesthesia employed(p > 0.05). Four patients experienced complications after reduction. One developed septal deviation and three nasal obstruction. But, no secondary operations were needed. Conclusion: Anterior ethmoidal nerve block and dorsal periosteal injection of 2% Xylocaine, combined with topical intranasal 4% lidocaine and epinephrine provided sufficient analgesia comparable to that of general anesthesia.

Background: Inferior alveolar nerve block (IANB) of the mandible is commonly used in the oral cavity as an anesthetic technique for dental procedures. This study evaluated the success rate of the first IANB administered by dental practitioners. Methods: Volunteer dental practitioners at Mahidol University who had never performed an INAB carried out 106 INAB procedures. The practitioners were divided into 12 groups with their advisors by randomized control trials. We recorded the success rate via pain visual analog scale (VAS) scores. Results: A large percentage of the dental practitioners (85.26%) used the standard method to locate the anatomical landmarks, injecting the local anesthetic at the correct position, with the barrel of the syringe parallel to the occlusal plane of the mandibular teeth. Further, 68.42% of the dental practitioners injected the local anesthetic on the right side by using the left index finger for retraction. The onset time was approximately 0-5 mins for nearly half of the dental practitioners (47.37% for subjective onset and 43.16% for objective onset), while the duration of the IANB was approximately 240-300 minutes (36.84%) after the initiation of numbness. Moreover, the VAS pain scores were $2.5{\pm}1.85$ and $2.1{\pm}1.8$ while injecting and delivering local anesthesia, respectively. Conclusions: The only recorded factor that affected the success of the local anesthetic was the administering practitioner. This reinforces the notion that local anesthesia administration is a technique-sensitive procedure.

Epidural anesthesia has significantly advanced in neuraxial anesthesia and analgesia. It is used for surgical anaesthesia and treatment of chronic pain. Hearing loss during or after epidural anesthesia is rare, and it is known to occur by the change of the intracranial pressure. Cerebrospinal fluid is connected with perilymph in the cochlear and vestibule that is important to hearing and balance. If the intracranial pressure is abruptly transferred to the inner ear, perilymph can be leak, that called perilymphatic fistula, dizziness, and hearing loss can occur suddenly. We report a 65-year-old woman who presented with acute onset dizziness and hearing loss during the epidural nerve block for back pain, wherein we speculated a possibility of perilymphatic fistula as the mechanism of hearing loss and dizziness. The mechanism of dizziness and hearing loss was suspected with perilymphatic fistula.

A 34-year-old man who previously underwent a craniotomy due to oligodendroglioma was admitted with a diagnosis of recurrent brain tumor. An awake craniotomy was planned. Approximately 15 minutes after completing the scalp nerve block, his upper torso suddenly moved and trembled for 10 seconds, suggesting a generalized clonic seizure. He recovered gradually and fully in 55 minutes without any neurological sequelae. The emergency computed tomography scan revealed a localized fluid collection and small intracerebral hemorrhage nearby in the temporoparietal cortex beneath the skull defect. He underwent surgery under general anesthesia at 8 hours after the seizure and was discharged from the hospital after 10 days. This report documents the first case of generalized seizure that was caused by the accidental intracerebral injection of local anesthetics. Although the patient recovered completely, the clinical implications regarding the scalp infiltration technique in a patient with skull defects are discussed.

The purpose of this study was to investigate the effect of the characteristics of patients who underwent spinal nerve block on the fear of injection and the risk of radiation. Subjects were 137 patients (67 males, 70 females) who visited the Department of Anesthesiology and Pain Medicine in Cheongju. The method was conducted as a research study using a total of 28 questionnaires consisting of patient characteristics, experience characteristics of nerve block surgery, nerve block fear scale, and radiation risk perception scale. The reliability of the questionnaire response was secured with a Cronbach's alpha coefficient of 0.6 or higher. For statistical analysis, correlation was tested by descriptive statistics, frequency analysis, independent sample T-test, and Pearson and Spearman correlation coefficients by measurement scale and factor. As a result, the fear scale of nerve block was significantly higher in women than in men (p<0.05). The fear scale of nerve block injection was significantly higher in the first-visit patients than in the second-visited patients (p<0.05). However, there was no significant difference among all variables in radiation risk perception. In conclusion, patients undergoing spinal nerve block were more aware of the fear of injection than the risk of radiation exposure during the procedure.

Background: This study used bibliometric analysis of articles published about the topic of regional anesthesia from 1980-2019 with the aim of determining which countries, organizations, and authors were effective, engaged in international cooperation, and had the most cited articles and journals. Methods: All articles published from 1980-2019 included in the Web of Science database and found using the keywords regional anesthesia/anaesthesia, spinal anesthesia/anaesthesia, epidural anesthesia/anaesthesia, neuraxial anesthesia/anaesthesia, combined spinal-epidural, and peripheral nerve block in the title section had bibliometric analysis performed. Correlations between the number of publications from a country with gross domestic product (GDP), gross domestic product (at purchasing power parity) per capita (GDP PPP), and human development index (HDI) values were investigated with the Spearman correlation coefficient. The number of articles that will be published in the future was estimated with linear regression analysis. Results: Literature screening found 11,156 publications. Of these publications, 6,452 were articles. The top 4 countries producing articles were United States of America (n = 1,583), Germany (585), United Kingdom (510), and Turkey (386). There was a significant positive correlation found between the GDP, GDP PPP, and HDI markers for global countries with publication productivity (r = 0.644, P < 0.001; r = 0.623, P < 0.001, r = 0.542, P < 0.001). The most productive organizations were Harvard University and the University of Toronto. Conclusions: This comprehensive study presenting a holistic summary and evaluation of 6,452 articles about this topic may direct anesthesiologists, doctors, academics, and students interested in this topic.

Paravertebral anesthesia for operation of abdominal wall in Korean cattle were effectively accomplished with the following technique. Any problems in surgical procedure were not observed under the block of ventral branches of the last thoracic nerve and the first and second lumbar nerves with the administration of preanesthetic. The site of injection for blocking of ventral branches of the thirteenth thoracic nerve were approximately 5cm lateral to the midline from the posterior edge of spinous process of the 13th thoracic vertebra and about 10ml of local anesthetic was injected immediately anterior to the transverse process of the first lumbar vertebra through thin site. The block of ventral branches of the first and second lumbar nerves were obtained by injecting 10ml of local anesthetic immediately below the posterior edge of transverse process of the 2nd and 4th lumbar vertebra, respectively.
