Transient cortical blindness is a known complication of iodinated contrast administration and is believed to reflect osmotic injury or autoregulatory dysfunction of the posterior circulation. Here, we report 2 cases of postangiography transient cortical weakness, a rare clinical analog to transient cortical blindness that affects the anterior circulation. The symptoms, timeline, and imaging findings of transient cortical weakness are distinct from more common post-procedural complications such as acute ischemic stroke or transient ischemic attack.

Inflammatory abdominal aortic aneurysms (IAAA) are a distinct subcategory of abdominal aortic aneurysms that make up roughly 5%-10% of all abdominal aortic aneurysm (AAA) cases. Inflammatory AAA (IAAA) is distinguished from traditional atherosclerotic AAA by the triad of thickened aneurysm wall, extensive perianeurysmal/retroperitoneal fibrosis, and dense adhesions of adjacent abdominal organs. The purpose of this report is to examine the clinical course of a rare case of inflammatory abdominal aortic aneurysm with aortocaval fistula.

To our knowledge, there have been no previous reports of biliary injury or bilomas due to microvalve infusion catheters (Trinav Infusion System; Westminster, CO). Here, we describe an interesting case of large hepatic biloma following bland hepatic arterial embolization with an antireflux catheter.

The FlowTriever System (Inari Medical, Irvine, California) is the first FDA-approved mechanical thrombectomy device used for treatment of pulmonary embolism. This device enables nonsurgical removal of pulmonary blood clots without the use of thrombolytic medication and its associated risks. We report 2 cases of successful application of the Inari FlowTriever in treatment of pulmonary embolism and right atrial thrombus.

The electrochemical interface (EI) is the determining factor in the yield and mechanism of sustainable energy storage and conversion systems due to its intrinsic functionality as a dynamic junction with the symmetry breaking of the molecular arrangement for complex reaction fields of mass transport and heterogeneous electron transfer. At the EI, the externally applied potential stimulus drives the formation of the electrical double layer (EDL) and governs the adsorption of interfacial adsorbate species in aqueous electrolyte solutions. Water and its aqueous electrolyte systems are integral and quintessential elements in the technological innovation of various fields such as environmental sciences, electrocatalysis, photocatalysis, and biochemistry. Although deciphering the structure and orientation of water molecules at the electrode–electrolyte interface in a quantitative analysis is of utmost importance, assessing chemical phenomena at the buried EI was rather challenging due to the intricacy of selecting interface-specific methodologies. Based on the non-centrosymmetry of the interfaces' electronic properties, sum-frequency generation (SFG) spectroscopy has been manifested to be specifically well suited for probing the EI with detailed and comprehensive characteristics of adsorbates' chemical structures and electrochemical events. In this review, we holistically engage in a methodical and scrupulous assessment of the fundamental EDL models and navigate towards the connection of the renowned Stark effect and potential dependence of SFG spectra at heterogeneous electrode–electrolyte interfaces. We dissect the development, advantages, and available geometrical configurations of in situ SFG spectroscopy in harnessing the EI. A broad spectrum of applications in unraveling the water orientations and rationalizing the convoluted mechanism of fuel-generated electrocatalytic reactions with particular encumbrances and potential resolutions is underscored by leveraging SFG spectroscopy.

Background. The coexistence of a granulosa cell tumor with a teratoma is extremely rare and impossible to diagnose preoperatively. For most patients with advanced age and stage, the standard treatment is hysterectomy and bilateral salpingo-oophorectomy; however, fertility-preserving surgery should be considered for young nulligravid women. Case. We present a case of a 24-year-old nulligravid female with bilateral adnexal masses, imaging findings of ovarian teratomas, and normal levels of tumor markers. A laparotomy revealed bilateral dermoid cysts, and solid tissue invaded most of the remaining ovarian parenchyma with no signs of malignancy in the uterus and peritoneum space. Consequently, a bilateral oophorectomy was performed to preserve her fertility. Histopathology examination showed mature cystic teratomas coexisting with granulosa cell tumors on both ovaries. Within six months, there were no signs of recurrence on ultrasonography and tumor makers. Combined oral contraceptive pills were prescribed as hormone replacement therapy. Conclusion. Fertility-preserving surgery can be performed in young women with an ovarian granulosa cell tumor coexisting with a teratoma. Long-term examination, hormone replacement therapy, and in vitro fertilization are required.

Abstract Background Tetanus remains common in many low- and middle-income countries, but as critical care services improve, mortality from tetanus is improving. Nevertheless, patients develop severe syndromes associated with autonomic nervous system disturbance (ANSD) and the requirement for mechanical ventilation (MV). Understanding factors associated with worse outcome in such settings is important to direct interventions. In this study, we investigate risk factors for disease severity and long-term physical outcome in adults with tetanus admitted to a Vietnamese intensive care unit. Methods Clinical and demographic variables were collected prospectively from 180 adults with tetanus. Physical function component scores (PCS), calculated from Short Form Health Survey (SF-36), were assessed in 79 patients at hospital discharge, 3 and 6 months post discharge. Results Age, temperature, heart rate, lower peripheral oxygen saturation (SpO2) and shorter time from first symptom to admission were associated with MV (OR 1.03 [ 95% confidence interval (CI) 1.00, 1.05], p = 0.04; OR 2.10 [95% CI 1.03, 4.60], p = 0.04; OR 1.04 [ 95% CI 1.01, 1.07], p = 0.02); OR 0.80 [95% CI 0.66, 0.94], p = 0.02 and OR 0.65 [95% CI 0.52, 0.79, p

Autoimmune encephalitis is a group of disorders characterized by symptoms of dysfunction of the limbic and extra‐limbic systems that occur in association with antibodies against intracellular antigens, synapses, or proteins located on the surface of nerve cells. Anti‐NMDA (N‐methyl‐D‐aspartate) receptor encephalitis was first described in 2007 and has become one of the most commonly recognized autoimmune encephalitides. The disease is predominantly female (81%) and affects young patients (37% <18 years old, 95% <45 years old), with up to 58% of women over 18 years old having ovarian teratoma. Clinical symptoms of anti‐NMDA receptor encephalitis include psychiatric disorders (anxiety, agitation, bizarre behavior, hallucinations, delusions, and memory impairment); seizures and epileptic states; and other neurologic symptoms (muscle tone abnormalities, eye movement disorders, and central ventilatory disorders). Diagnosis of this condition can be difficult due to the non‐specific nature of the symptoms, often leading to delays in appropriate treatment. Early diagnosis and timely treatment of anti‐NMDA receptor encephalitis, especially in young women with ovarian teratoma, has significantly improved the chances of full recovery and improved reproductive health outcomes for patients.

We report a flexible and noninvasive method based on field-effect transistors hybridizing semiconducting single-walled carbon nanotubes for monitoring the effects of histamine on Ca2+ release from the intracellular stores of a nonexcitable cell. These nanodevices allowed us to evaluate the real-time electrophysiological activities of HeLa cells under the stimulation of histamine via the recording of the conductance changes of the devices. These changes resulted from the binding of histamine to its receptor type 1 on the HeLa cell membrane. Moreover, the effects of chlorphenamine, an antihistamine, on the electrophysiological activities of a single HeLa cell were also evaluated, indicating that the pretreatment of the cell with chlorpheniramine decreased intracellular Ca2+ release. Significantly, we only utilized a single nanodevice to perform the measurements for multiple cells pretreated with various concentrations of chlorphenamine. This enabled the statistically meaningful analysis of drug effects on cells without errors from device variations. Obtained results indicated the novel advantages of our method such as real-time monitoring and quantitative capability. Our devices, therefore, can be efficient tools for biomedical applications such as electrophysiology research and drug screening.

The baffle in the air collector duct increases heat transfer, while also significantly increasing the pressure loss penalty. Pressure loss reduction can be achieved using the unequal baffle pitch which is proposed in this study. In the current paper, a numerical investigation of an air collector duct with inclined baffles is presented. Inclined baffles spaced with successive ratio (r) from 1 to 1.4 and Reynolds number (Re) of air from 2370 to 13250 were varied to evaluate Nusselt number, friction factor and effective efficiency of the collector. 2D numerical simulations with the standard k-ε turbulence model were performed to clarify the flow mechanism through baffles. The results show that pressure loss in case of r > 1 significantly reduces compared to that of r = 1. Therefore, the maximum effective efficiency of the baffled collector duct with successive ratios from 1 to 1.3 is the same and equals to 0.6. It is better to install dense baffles near the inlet than dense baffles near the outlet because many baffles concentrated on the inlet create high turbulence in the rest of the air collector duct.

Introduction: Full arch reconstruction with dental implants is considered as a reference for dental rehabilitation. However, there are some limitations with patient affected by severe maxilla, mandible atrophy and dento-skeletal-disharmony. These defaults can be corrected with orthognathic surgery and several bone grafts. Observations: A partially edentulous 65-year-old female patient with a skeletal class II by mandibular retrognathia was treated with mandibular advancement osteotomy and simultaneous insertion of four fully guided implants with immediate screwed zirconia prostheses loading in just one session. Conclusion: Simultaneous bilateral sagittal split osteotomy with a full arch rehabilitation by implant with immediate loading by zirconia prosthesis seems to be a reliable and predictable approach to treat skeletal class II patient with a fixed solution. Virtual planning was compulsory to be able to perform this surgery with accuracy.

Background:. There is minimal information describing the common characteristics among patients seeking primary/revision rhinoplasty. Success is traditionally interpreted from the surgeon's viewpoint, without considering the patient's perspective. The study's aims were to (1) identify/compare anatomic and functional characteristics commonly found in patients seeking primary and revision rhinoplasties; (2) assess patient satisfaction using a survey; and (3) explore whether graft choice (auricular cartilage versus rib cartilage) affects patient satisfaction and outcome in revision rhinoplasty. Methods:. A retrospective review of all rhinoplasties by a single surgeon from June 2016 to January 2020 was performed, focusing on preoperative anatomic/functional characteristics and operative interventions performed. A survey was then used to assess patient satisfaction. Finally, survey outcomes were compared between patients who received auricular and rib cartilage grafts in revision rhinoplasty. Results:. A total of 102 rhinoplasties (53 primary and 49 revisions) were included. Primary rhinoplasties were noted to have more patients with “big” noses (P = 0.015) or humps (P < 0.010). Patients undergoing revision rhinoplasties more commonly exhibited middle vault collapse (P = 0.022). The survey response rate was 60%. Revision rhinoplasty patients had a higher incidence of dissatisfaction with their outcome Conclusions:. Several features among patients seeking revision rhinoplasties could have been created in the primary operation. The rhinoplasty surgeon should be careful to not introduce new issues or create worse deformities than those seen following the initial operation. Survey-based outcome analysis demonstrated that revision rhinoplasty patients are more likely to have a greater rate of dissatisfaction following their operation.
