Sudden bilateral hearing loss is mainly caused by peripheral otologic disorders or psychogenic origins. Bilateral temporal lobe infarcts can be one of the rare causes. We report a 50-year-old man presented with cortical deafness due to bilateral temporal lobe infarctions. He was admitted at hospital because he did not respond to any verbal questions or environmental sounds, although he understood written commands partially and spoke fluently. Brain MRI demonstrated ischemic infarcts in both temporal lobes involving primary auditory cortex.

BACKGROUND: Paradoxical embolism through the patent foramen ovale (PFO) is a well-recognized mechanism for otherwise unexplained ischemic stroke. Although transthoracic contrast echocardiography (TCE) has been used frequently for noninvasive diagnosis of right to left shunt through PFO, its diagnostic accuracy appears limited, especially in patients with poor acoustic window. Since harmonic imaging (HI) can enhance the definition of contrast microbubbles, theoretical advantages of HI in the detection of right to left shunt through PFO using microbubbles can be considered. However, there are few data regarding the diagnostic efficacy of HI in the detection of right to left shunt through PFO. The purpose of this study was to compare the diagnostic value of transthoracic HI in the detection of right to left shunt through PFO in patients with stroke with that of fundamental imaging (FI). Methods: One hundred thirty-six consecutive patients with stroke (82 male, mean age:9) underwent TCE in both HI and FI and transesophageal echocardiography (TEE) during rest and Valsalva maneuver with intravenous administration of agitated saline. PFO was judged to be present if microbubbles appeared in the left atrium within 3 cardiac cycles of their appearance in the right atrium. TEE was regarded as the gold standard for assessing the diagnostic accuracy of TCE. Results: Right to left shunt through PFO was detected in 40 of 136 patients by TEE (29.4%). FI of TCE detected shunt through PFO in only 9 of 136 patients (6.6%). In contrast, HI detected shunt through PFO in 25 of 136 patients (18.4%). The overall sensitivity and specificity of FI and HI for detection of right to left shunt through PFO were 22.5%, 62.5% (p<0.05) and 100%, 100%, respectively. Valsalva maneuver during HI significantly increased the detection rate of shunt through PFO (during rest in 9 and during Valsalva maneuver in 25, p<0.05). CONCLUSION: HI with contrast microbubble injection significantly enhanced the detection of right to left shunt through PFO in patients with ischemic stroke compared with FI by transthoracic approach.

The incidence and the nature of visual involvement in Friedreich's ataxia who showed progressive visual impairment a few years before developing characteristic clinical manifestations of Friedreich's ataxia. The progress of disease in this case suggests that visual involvement may be from the same pathogenetic mechanism of peripheral nervous system in Friedreich's ataxia.

Splenic metastasis resulting from solid tumors is a rare event, and it is most often diagnosed at the time of autopsy. In those cases of widely disseminated cancer, splenic involvement may be fairly common, but solitary splenic metastasis in the absence of other metastases is exceedingly rare. The reported primary malignancies of patients with splenic metastases include lung, colorectal, endometrial, ovarian, thyroid, pancreatic, gastric cancers and most commonly, melanoma. The author report here on a case of 55- year-old male who was found to have a solitary splenic metastasis 12 months after undergoing a left upper lobectomy for stage Ib (pT2N0M0) adenocarcinoma of the lung and he was then treated by splenectomy.

Severely worn dentition causes various complications such as loss of tooth structure, discoloration, pulp complications and loss of function and aesthetics. In this case, the patient showed particularly severe attrition in the anterior teeth and lack of space for restoration. The amount of vertical dimension was determined based on the diagnostic wax up, and the patient’s adaptation was evaluated by using a removable occlusal splint for 6 weeks. Thereafter, the coordination of the muscular nervous system, aesthetics, temporomandibular joint were re-evaluated for 3 months by restoring the fixed provisional restoration. Through the above treatment process, the final restoration was completed with full mouth fixed prosthesis using monolithic zirconia, and functionally and aesthetically stable results were obtained.

Background: Interscalene brachial plexus block (ISBPB) is commonly used with general anesthesia for postoperative pain management in shoulder surgery. This study investigated the incidence of hypothermia and changes in the body temperature in patients undergoing arthroscopic shoulder surgery under ISBPB with propofol sedation. Methods: This retrospective study enrolled 220 patients who underwent arthroscopic shoulder surgery. Patients were divided into general anesthesia (n = 34) and ISBPB with propofol sedation (n = 186) groups, and medical records were retrospectively compared. In addition, patients from the ISBPB group were further divided according to age (elderly, [≥ 65 years]; n = 98 vs. young, [< 65 years]; n = 88), and the incidence of hypothermia and changes in the body temperature were compared. Results: Twenty-seven patients (12.3%) experienced perioperative hypothermia (range; 35.3–35.9℃). The incidence of perioperative hypothermia was 29.4% and 9.1% in the general anesthesia and ISBPB groups, respectively, and there was a significant difference between the two groups (P = 0.002). The incidence of perioperative hypothermia according to age in the ISBPB group was 9.2% and 9.1% in the elderly and young groups, respectively, and there was no significant difference between the two groups (P = 0.983). Conclusions The incidence of perioperative hypothermia during arthroscopic shoulder surgery under ISBPB with propofol sedation is lower than that under general anesthesia. Furthermore, when using ISBPB with propofol sedation, the incidence of perioperative hypothermia in elderly patients is similar to that in younger patients.

Herpes zoster ophthalmicus (HZO) is an infectious disease that results from the reactivation of latent varicella zoster virus in the ophthalmic branch of the trigeminal ganglia. HZO manifests with herpes zoster-like symptoms such as rash with or without signs of ocular involvement. Cavernous sinus thrombosis (CST) is a life-threatening condition accompanied by signs and symptoms involving the eyes and the cranial nerves. Case: We report a case of septic cavernous sinus thrombosis (caused by Streptococcus constellatus ssp. constellatus) which was masked by the simultaneous occurrence of HZO in this patient, resulting in delayed diagnosis. Conclusions: CST may be obscured by HZO, prompt diagnosis and treatment is necessary when such case arrive.

Background: Oocyte retrieval is the most important procedure in in vitro fertilization (IVF). Various anesthetic methods are used to control a patient’s anxiety and pain during IVF; however, there are no recommended anesthetic methods at present. In this study, we retrospectively investigated chemical pregnancy rates according to the anesthetic method used for oocyte retrieval. Methods: We reviewed records of patients who underwent oocyte retrieval between January 1, 2012 and December 31, 2017. Patients were divided into the spinal anesthesia (SA) and monitored anesthesia care (MAC) groups. The primary outcome was chemical pregnancy rate after IVF. Results: The study included 95 patients. SA was administered in 77 (81%) and MAC in 18 (19%). The overall chemical pregnancy rate was 32.6% (31/95). According to the anesthetic method, the pregnancy rate was 32.5% (25/77) in the SA group and 33.3% (6/18) in the MAC group. There was no statistical difference in the pregnancy rate between the groups (P = 0.575). The procedural time was significantly shorter in the SA group than in the MAC group (P < 0.001). Conclusions Chemical pregnancy rates were not significantly different between the SA and MAC groups. However, the procedure duration was shorter in the SA group than in the MAC group.

Background: Endoscopic procedures of the esophagus are more complicated than those of other regions of the gastrointestinal tract. They have a relatively long procedure time and high risk of complications, such as perforation and bleeding. Perforations that occur during the procedure can accompany pneumoperitoneum and pneumomediastinum through leakage of insufflation air and cause severe ventilatory impairment.Case: A 58-year-old male patient underwent enucleation of leiomyoma in the esophagus using endoscopy under general anesthesia. Ventilatory impairment occurred 15 min after commencement of the procedure. Subsequently, subcutaneous emphysema and severe abdominal distension were observed. We suggested the possibility of microperforation during the procedure to the endoscopist, and he performed endoscopic clipping around the excision site of leiomyoma. Conclusions Providing anesthetic care by anesthesiologists during endoscopic procedures is considered necessary for patient safety. Complications of endoscopic procedures can be detected and managed early without sequelae during anesthetic care.
