Since prehistoric times, man has sought ways to lessen pain. With varying degrees of success he has utilized: opium, nerve compresses, cold, hypnosis, etc. New ideas for using ether and laughing gas in anesthesia on the beginning of eighteen century, were first steps in developing general anesthesia. The dental and medical professions are thankful to all participants in history of anesthesia for their great contributions. .

Joint Injections

There are a variety of anesthetic techniques commonly used for sacroiliac joint (SIJ) procedures. For example, diagnostic SIJ injections do not necessitate anesthesia, while open SIJ fusions require general anesthesia. This chapter, targeted to practitioners performing SIJ procedures, covers the basic elements of these techniques. After a brief discussion of the history of anesthesia in relation to SIJ procedures, each common anesthetic technique is discussed, in order of increasing sedation. Local anesthesia is discussed for intraarticular joint injections, blocks of the nerves innervating the SIJ, and radiofrequency ablations of these same nerves. Monitored anesthesia care is discussed for procedures such as minimally invasive SIJ fusions and the Simplicity radiofrequency ablation technique. The use of neuraxial anesthesia, via either spinal or epidural blocks, is considered for lateral SIJ fusions. Finally, the use of general anesthesia for lateral and open fusions is reviewed.

Tuzo Wilson introduces the concept of transform faults, which has the effect of transforming Earth Science forever. Resistance to the new ideas is finally overcome in the late 1960s, as the theory of moving plates is established. Two scientists play a major role in quantifying the embryonic theory that is eventually dubbed ‘plate tectonics’. Dan McKenzie applies Euler’s theorem, used previously by Teddy Bullard to reconstruct the continents around the Atlantic, to the problem of plate rotations on a sphere and uses it to unravel the entire history of the Indian Ocean. Jason Morgan also wraps plate tectonics around a sphere. Tuzo Wilson introduces the idea of a fixed hotspot beneath Hawaii, an idea taken up by Jason Morgan to create an absolute reference frame for plate motions.

The Impact

While several women’s movements that aimed to modify their relationship with public space were taking place across the world, in 1956, the Mexican Social Security Institute founded the program Casa de la Asegurada, the subject of this study, as a tool for improving the social security of Mexican families through the input of cultural, social, artistic, and hygienic knowledge for women. The program’s facilities, Casas de la Asegurada, are located in the large Mexican housing complexes, articulating themselves to the existing city. Despite the impact on the lives of Mexican families, these have been ignored throughout the history of Mexican architecture. The main objective of this paper is to show the state of the art of Casa de la Asegurada and its facilities located in Mexico City. To achieve this, the greatest number available of primary sources on the topic was compiled through archive and document research. Sources were classified identifying information gaps to explain, in three different scales (program, facilities, and a case study), how they work through their objectives, performed activities, and evolved through time, so that the gathered information is analyzed with an urbanistic, architectural, and gender approach to contribute new ideas in the building of facilities that allow women empowerment.

Objectives: Postoperative urinary retention (POUR) is influenced by many factors, and its reported incidence rate varies widely. This study aimed to investigate the occurrence and risk factors for urinary retention following general anesthesia for endoscopic nasal surgery in male patients aged >60 years. Methods: A retrospective review of medical records between January 2015 and December 2019 identified 253 patients for inclusion in our study. Age, body mass index (BMI), a history of diabetes/hypertension, American Society of Anesthesiologists (ASA) classification, and urologic history were included as patient-related factors. Urologic history was subdivided into 3 groups according to history of benign prostate hyperplasia (BPH)/lower urinary tract symptoms (LUTS) and current medication. The following was analyzed as perioperative variables for POUR development: duration of anesthesia and surgery; amount of fluid administered; rate of fluid administration; intraoperative requirement for fentanyl, ephedrine, and dexamethasone; postoperative pain; and analgesic use. Preoperatively measured prostate size and uroflowmetry parameters of patients on medication for symptoms were compared according to the incidence of urinary retention. Results: Thirty-seven (15.7%) patients developed POUR. Age (71.4 vs 69.6 years), BMI (23.9 vs 24.9 kg/m2), a history of diabetes/hypertension, ASA classification, and perioperative variables were not significantly different between patients with and without POUR. Only urologic history was identified as a factor affecting the occurrence of POUR ( P = .03). The incidence rate among patients without urologic issues was 5.9%, whereas that among patients with BPH/LUTS history was 19.8%. Among patients taking medication for symptoms, the maximal and average velocity of urine flow were significantly lower in patients with POUR. Conclusions: General anesthesia for endoscopic nasal surgery may be a potent trigger for urinary retention in male patients aged >60 years. The patient’s urological history and urinary conditions appear to affect the occurrence of POUR.

Abstract Background Excessive dynamic airway collapse (EDAC) is an uncommon cause of high airway pressure during mechanical ventilation. However, EDAC is not widely recognized by anesthesiologists, and therefore, it is often misdiagnosed as asthma. Case presentation A 70-year-old woman with a history of asthma received anesthesia with sevoflurane for a laparotomic cholecystectomy. Under general anesthesia, she developed wheezing, high inspiratory pressure, and a shark-fin waveform on capnography, which was interpreted as an asthma attack. However, treatment with a bronchodilator was ineffective. Bronchoscopy revealed the collapse of the trachea and main bronchi upon expiration. We reviewed the preoperative computed tomography scan and saw bulging of the posterior membrane into the airway lumen, leading to a diagnosis of EDAC. Conclusions Although both EDAC and bronchospasm present as similar symptoms, the treatments are different. Bronchoscopy proved useful for distinguishing between these two entities. Positive end-expiratory pressure should be applied and bronchodilators avoided in EDAC.

Epithelioid angiosarcoma is a rare and highly aggressive soft tissue angiosarcoma most commonly arising in the deep soft tissues. Given that abundant vascular cavities anastomose with each other, most angiosarcomas prone to metastasis recur quickly, and the overall prognosis is poor. We report a 25-year-old woman at 24 weeks’ gestation who presented with a 1-month history of abdominal distension. Ultrasonography suggested a mass in the right adnexa, and she underwent two operations owing to uncontrolled intraperitoneal bleeding with progressive anemia. The right ovarian tumor and right adnexa were removed successively. Biopsy yielded a diagnosis of primary epithelioid angiosarcoma with mature cystic teratoma. The patient died from uncontrolled progressive bleeding 1 week after the second operation. This case revealed that epithelial angiosarcoma is a highly malignant endothelial cell tumor. The results of surgery and chemoradiotherapy tend to be poor, and the recurrence rate is high. The purpose of this study is to raise clinical awareness of epithelial angiosarcoma and its adverse events and to provide new ideas for the treatment of these adverse events. Immunohistochemical staining of pathological specimens can facilitate diagnosis. Pregnancy with malignant tumors may lead to rapid disease progression, extensive lesions, and a poor prognosis.

AbstractWe conducted a retrospective analysis of 497 patients who underwent tonsillectomy at Kamio Memorial Hospital from September 2015 to August 2018. A total of 35 cases (7.0%) developed postoperative bleeding and three cases (0.6%) needed a second operation under general anesthesia to stop the bleeding. Postoperative bleeding most frequently occurred between 24 hours and 6 days after the operation. The incidence of postoperative bleeding was significantly higher in males and in patients aged 20 to 39 years old. The operation time, body mass index, smoking habit, and history of hypertension were not identified as clinical risk factors for bleeding after tonsillectomy in this study.
