Background Mental nerve (MN) injuries are reported during transoral endoscopic thyroidectomy vestibular approach. Effect of trocar insertion and position on MN are examined in the present study. Materials and methods Ten millimeter incision was made at the center of the lower lip oral vestibule. Two 5 mm lateral incisions of the lower lip oral vestibule were made at the junction between the incisor and the canine. These 2 lateral incisions were high, just below the edge of lower lip. Nine pigs (18 MN) were randomly divided into 3 groups and MN dissection was performed. The angle between the lateral ports and median line were changed between 15 and 45 degrees among 3 groups and effect on MN was examined. Results During dissection when insertion and other ports are in neutral position visual inspection of MNs did not reveal any compression bilaterally. The distance between MN and the ports was 18.2±2.1 mm (16.3 to 21.2 mm). In group I and group II, MNs have no compression by the lateral trocars. In group III (45 degrees), left MNs were all compressed. Two MNs (66.7%) were compressed on the right side. The MN was compressed at its ramification. Conclusions The results of the present experimental study, endorse the suggested medial and lateral vestibular incisions for transoral endoscopic thyroidectomy vestibular approach. However, during dynamic modification of the lateral port position/angle, MN compression was observed when the angle was >45 degrees.Purpose of review We present information on cannabis policy, demand, and supply in the Asia-Pacific region. EN450 inhibitor Method A systematic review of peer-reviewed articles using PubMed, MEDLINE, and reliable sources was conducted. We classified the policy implemented in each country into conducting research, legalization of medical and recreational use, decriminalization, cultivation, and others. Recent findings In Australia, New Zealand, and Thailand, medical use has been approved, whereas it is limited in South Korea and Singapore and illegal in other countries. Except Australia, none of the Asia-Pacific region countries allows recreational use. China and Japan are expected to approve medical use, whereas Australia and New Zealand work on decriminalization. Most cultivation is allowed and regulated for medical use. Cannabis seizures have changed in accordance with these policies. Although the national surveys of four countries, that is, Australia, New Zealand, Japan, and Thailand were conducted in different years, the use of cannabis among the general population has increased. Summary Any change in the legal status of cannabis must be undertaken with caution and fully evaluated at each stage to determine the extent to which these changes are leading to increased numbers of users, oversupply, and health risks including cannabis-related harm.Objective To characterize symptoms and disease severity among pregnant women with coronavirus disease 2019 (COVID-19) infection, along with laboratory findings, imaging, and clinical outcomes. Methods Pregnant women with COVID-19 infection were identified at two affiliated hospitals in New York City from March 13 to April 19, 2020, for this case series study. Women were diagnosed with COVID-19 infection based on either universal testing on admission or testing because of COVID-19-related symptoms. Disease was classified as either 1) asymptomatic or mild or 2) moderate or severe based on dyspnea, tachypnea, or hypoxia. Clinical and demographic risk factors for moderate or severe disease were analyzed and calculated as odds ratios (ORs) with 95% CIs. Laboratory findings and associated symptoms were compared between those with mild or asymptomatic and moderate or severe disease. The clinical courses and associated complications of women hospitalized with moderate and severe disease are described. Results Of 158 moderate or severe disease, including a small proportion with prolonged critical illness who received ICU or step-down-level care.Purpose To report two cases of idiopathic intraocular cilia presenting as sectoral scleritis with progressive intraocular inflammation. Methods Both patients were treated with intravitreal antibiotics and underwent pars plana vitrectomy where the cilia were removed and identified on histopathology. Results One patient developed a retinal detachment while being treated for presumed endophthalmitis. The intraocular cilium was discovered during pars plana vitrectomy. In the second case, the cilium was detected on dilated fundus exam and was believed to be the cause of the patient's scleritis and vitritis. Therapeutic vitrectomy was performed. In both cases, the cilia were positively identified on histopathology. Conclusion Idiopathic intraocular penetration of cilia should be considered in the differential diagnosis of sectoral scleritis with progressive intraocular inflammation.Purpose Previous population-based and hospital-based studies have shown an association between high myopia and higher prevalence of glaucomatous or glaucoma-like optic neuropathy (GON). Here we discuss potential factors associated with such a correlation. Design Review. Methods Findings from population-based and clinical investigations were combined with observations from light-microscopical examinations of human eyes. GON was defined by an abnormal shape of the neuroretinal rim as shown by a vessel kinking close to optic disc border in the inferior, superior, or nasal optic disc region. Results The prevalence of GON increased (P 33 mm. It was associated with a larger optic disc and/or larger parapapillary delta zone. Histological factors potentially associated with the myopia-related increased GON prevalence were an elongation and thinning of the lamina cribrosa resulting in intra-lamina changes and a steepening of the translamina cribrosa pressure gradient; a lengthening and thinning of the peripapillary scleral flange which is the ophthalmoscopical equivalent of parapapillary delta zone and acts as the biomechanical anchor of the lamina cribrosa; and an increased distance of the peripapillary arterial circle of Zinn-Haller to the lamina cribrosa, due to the elongation of the peripapillary scleral flange. In addition to GON, a nonglaucomatous optic nerve damage may occur in the papillo-macular region due to a parapapillary gamma zone-associated lengthening of the retinal nerve fibers. Conclusions In highly myopic eyes, one should be vigilant not to overlook GON. Abstract A loss or lack of blood supply to the eye can result in acute loss of vision. The site of ischemia may be at the level of the retinal arterioles, the central retinal artery, or further back at the ophthalmic and internal carotid artery. Recognizing the symptoms and signs are important to help prevent permanent ischemic and irreversible blindness. The objective of this review article is to provide the general ophthalmologists with information on how to recognize the symptoms and to best manage these patients. The management is to investigate for the cause of the transient monocular visual loss and to apply secondary prevention to address atherosclerotic risk factors to prevent further ischemic events like a stroke.Halogenated ethers, such as desflurane, sevoflurane, and isoflurane, are known to exert an array of effects besides sedation. However, the postanesthetic effects of desflurane remain undiscovered as no study has explored these effects systematically. Phenotypic screening using behavioral test batteries is a powerful method to identify such effects. In the present study, we behaviorally phenotyped desflurane-treated mice to investigate postanesthetic effects. We applied comprehensive behavioral test batteries measuring sensorimotor functions, anxiety, depression, sociability, attention, and learning abilities, starting 7 days after anesthesia performed with 8.0% desflurane for 6 h. Although our previous study revealed postanesthetic effects of isoflurane in adult mice, in the current study, desflurane-treated mice exhibited no such effects in any behavioral test. To further examine whether desflurane affect behavior in more early time point, we built up a new additional test battery, which carried out 1 day or 3 days after exposure to desflurane. Mice treated with desflurane 1 day before testing showed more slips than other two groups in the first trial, suggesting mild acute side effects of desflurane on motor coordination. These results suggest the safety of desflurane in clinical settings and imply that postanesthetic effects are unique to each halogenated ether.Tardive dyskinesia is a serious, disabling, movement disorder associated with the ongoing use of antipsychotic medication. Current evidence regarding the pathophysiology of tardive dyskinesia is mainly based on preclinical animal models and is still not completely understood. The leading preclinical hypothesis of tardive dyskinesia development includes dopaminergic imbalance in the direct and indirect pathways of the basal ganglia, cholinergic deficiency, serotonin receptor disturbances, neurotoxicity, oxidative stress, and changes in synaptic plasticity. Although, the role of the glutamatergic system has been confirmed in preclinical tardive dyskinesia models it seems to have been neglected in recent reviews. This review focuses on the role and interactions of glutamate receptors with dopamine, acetylcholine, and serotonin in the neuropathology of tardive dyskinesia development. Moreover, preclinical and clinical results of the differentiated effectiveness of N-methyl-D-aspartate (NMDA) receptor antagonists are discussed with a special focus on antagonists that bind with the GluN2B subunit of NMDA receptors. This review also presents new combinations of drugs that are worth considering in the treatment of tardive dyskinesia.PRéCIS A survey among members of the American Glaucoma Society and the American Optometry Association on tonometer preference and tonometer disinfection indicates a shift to disposable tonometer tips compared to 1987. Purpose This survey's purpose was to determine how eye care providers responded to the 2008 Centers of Disease Control (CDC) tonometer disinfection guidelines, which recommend 10% hypochlorite (dilute bleach) for reusable tonometers. Tonometers measure the eye pressure when they touch the cornea, an essential part of the eye exam. Methods American Glaucoma Society (AGS) and American Optometry Association (AOA) members were surveyed on tonometer preference, tonometer use, disinfection process, disinfectants, disinfection timing, and tonometer damage. Results Survey responses from 79 AOA members and 197 AGS members are included. The Goldmann tonometer is considered most accurate (70, 89% AOA and 161, 82% AGS). It is preferred by 54 (70%) AOA and 193 (98%) AGS members. Many providers (165) use reusable Goldmann tonometer tips (77, 79% AOA, 88, 45% AGS), and most clean with 70% isopropyl alcohol wipes 59 (77%) AOA and 54 (61%) AGS. In summary, 126 of 276 participants (8, 10% AOA and 118, 60% AGS) follow CDC guidelines by using disposable tips (2 AOA and 109 AGS) or disinfecting reusable tips with 10% hypochlorite (6 AOA and 9 AGS). Conclusion The majority of AGS providers follow current CDC tonometer disinfection guidelines by shifting to disposable Goldmann tonometer tips. Only a minority of providers who use reusable tonometer tips disinfect with dilute bleach. Continued education on proper tonometer disinfection is critical to prevent eye-care related infection due to improper disinfection.
