Reverse pupillary block with intraocular pressure (IOP) elevation after cataract surgery with in-the-bag implantation of intraocular lens (IOL) is considered a very rare complication. We report the case of a 47-year-old female patient with bilateral high axial myopia and posterior staphyloma presented with left acute loss of vision and eye pain, headache, and vomiting 2 weeks after uneventful presenile cataract surgery with single-piece IOL implantation in the capsular bag 1 month and 2 weeks in the right and left eyes, respectively. Gonioscopy showed extremely wide angle in all quadrants compared to the other eye with Spaeth classification of E 60c + 2 (14). Ultrasound biomicroscopy of the left eye showed epithelial corneal edema, 4.56 mm-deep anterior chamber, abnormal iris configuration with posterior concavity, and angle opening ranging between 60° and 74°, with unremarkable posterior chamber IOL and ciliary body. We managed the patient with topical antiglaucoma medications and laser peripheral iridotomy. IOP returned to normal levels. The patient was followed for 12 consecutive months. Elevated IOP from the reverse pupillary block is a rare postoperative complication of cataract surgery. It was initially described in association with the ciliary sulcus implanted IOL. Elevated IOP from the reverse pupillary block was then reported associated with scleral sutured IOLs and Yamane technique, and most recently with in-the-bag implanted 3-piece-IOL. Herein, we report the first case of pseudophakic reverse pupillary block in association with in-the-bag implanted single-piece foldable acrylic IOL.

Intraoperative Acute Cardiac Tamponade as a Result of Intracardiac Perforation Requiring Emergency Continuous Pericardiocentesis and Open Sternotomy: A Case Report and Literature Review of a Rare but Fatal Complication.
Intraoperative acute cardiac tamponade associated with iatrogenic intracardiac perforation from percutaneous interventional cardiac procedures is a rare but potentially catastrophic complication. We report a case of intraoperative acute hemopericardium caused by a left atrial (LA) perforation resulting in cardiac tamponade in a patient undergoing a baffling procedure for the correction of two anomalous pulmonary veins draining into her superior vena cava (SVC) that required continuous pericardiocentesis with autologous blood transfusion via the femoral vein and an emergency intraoperative transfer from the interventional cardiology cath lab to the cardiac operating room for an open sternotomy and primary repair. An 86-year-old female with known right-ventricular (RV) failure with preserved ejection fraction (left ventricular ejection fraction (LVEF): 50-55% on transesophageal echocardiography (TEE) one week prior) and atrial fibrillation was admitted for her third heat failure exacerbation in two months despite being adherent to her aggressive diuresis medication regimen. Upon her readmission and due to her symptomatic and seemingly refractory heart failure, the patient underwent a cardiac computer tomography (CT) with 3D reconstruction that showed previously undiagnosed partial anomalous pulmonary venous return (PAPVR) of two of her four pulmonary veins aberrantly draining into the SVC. This anatomic pathology was deemed to be the likely etiology of her repeated episodes of recurring heart failure exacerbations, shortness of breath, peripheral edema, and fatigue. The patient was counseled and consented to a percutaneous baffle of the two anomalous veins to redirect more of the returning pulmonary venous blood away from the SVC and to the LA. While under general endotracheal anesthesia (GETA) with a TEE in place during the procedure, the patient suddenly developed acute hypotension, tachycardia, and a reduction in expired carbon dioxide (EtCO) was noted quickly followed by evidence of a rapidly accumulating hemopericardium on TEE. Cardiothoracic surgery was urgently consulted to the interventional cardiology cath lab while the patient underwent an emergency pericardiocentesis that momentarily alleviated her hemodynamic instability, cardiac tamponade physiology, and deteriorating overall clinical picture. While performing continuous pericardiocentesis with autologous return of the aspirated blood via femoral venous access the patient was urgently transported to the cardiac operating room and prepped for emergency sternotomy for primary repair of the LA. Following primary repair via sternotomy, multiple drains were placed and the thoracic cavity was closed with wires. The patient was immediately transported to the surgical intensive care unit (SICU) intubated, mechanically ventilated, and sedated. During this time, the patient progressively required additional vasoactive and inotropic agents to support her mean arterial pressure (MAP), and following a multidisciplinary discussion with the patient's family regarding her goals of care, the decision was made to withdraw further resuscitation efforts and the patient expired four hours later.

BACKGROUND
Adrenal cellular schwannomas are exceptionally rare stromal tumors that are often misdiagnosed due to the lack of specific radiological, serological, or clinical features. In this report, we describe the differential diagnosis of a rare adrenal cellular schwannoma.
METHODS
A 69-year-old man with a history of persistent hypertension, chronic kidney disease, hypertensive heart disease, and cardiac insufficiency was hospitalized due to bilateral lower extremity edema lasting for 3 months. Plain computed tomography at that time revealed a space-occupying lesion in the right adrenal gland. As serum levels of catecholamines, cortisol, and adrenocorticotropic hormone were within normal ranges, the edema was attributed to the chronic kidney disease and cardiac insufficiency, and the patient was referred to our hospital for surgical treatment. Contrast-enhanced computed tomography revealed heterogeneous enhancement in the adrenal mass indicating pheochromocytoma. An irregularly shaped 5 cm mass with a complete capsule in the right adrenal gland was laparoscopically resected. The postoperative histopathological diagnosis was adrenal cellular schwannoma.
RESULTS
The postoperative course was unremarkable and the tumor did not recur during 5 years of follow-up.
CONCLUSION
Adrenal cellular schwannoma is a very rare tumor that is extremely difficult to preoperatively diagnose. Histological and immunohistochemical analyses are required for differential diagnosis and confirmation. Cellular schwannomas can transform into malignant peripheral nerve sheath tumors, but not often. Consequently, regular postoperative follow-up is required for such patients, especially imaging.

Patients who present to pain clinics with complex regional pain syndrome (CRPS) typically have debilitating pain, including hyperalgesia and allodynia, and additional substantial quality-of-life concerns related to the motor and autonomic-related symptoms of CRPS. Present treatments for CRPS such as neuropathic pain medications and sympathetic blocks are often unsatisfactory for managing symptoms. The present cases highlight the use of a 60-day percutaneous peripheral nerve stimulation (PNS) treatment for three patients with CRPS Type I affecting the foot. In all three patients, the tibial and common peroneal nerves were targeted separately at the popliteal fossa with two percutaneous leads each placed a remote distance (~1 cm) from the target nerve under ultrasound guidance. All three patients reported substantial pain relief and resolution of autonomic symptoms (e.g., swelling, edema, erythema), with sustained relief lasting 8-10 months in two patients, and 34 months (as of this writing) in the third patient. There were no medical complications. These three cases suggest that 60-day PNS is a safe and efficacious treatment for CRPS.

Cardiovascular risk factors are the cause of atherosclerotic disease, which can involve all the elastic and muscolo-elastic arteries. The etiopathogenesis of atherosclerosis is multifactorial since genetics, lifestyle, and comorbidities can be simultaneously involved. Clinical manifestations can be heterogeneous and include myocardial infarction, stroke, aortic aneurysms, renal artery stenosis, renal insufficiency, peripheral artery disease, etc. Currently, 70% of clinical events cannot be prevented with available drug therapy, statins included, and at least 10% of coronary events occur in apparently healthy individuals in the absence of major traditional risk factors. The case of a young male with a history of coronary artery disease and multiple atherosclerotic risk factors not properly treated who was admitted to the emergency department for pulmonary edema and high blood pressure is presented. During the diagnostic workup, a dramatic atherosclerotic involvement of all arterial trees emerged. Moreover, the patient presented with thrombosis of the right subclavian artery, which was treated with a heparin infusion and later complicated by cerebral hemorrhage with residual hemiplegia.

Indole-chalcone hybrids have burst into prominence as potent weapons in the battle against pain and inflammation due to their unique features, allowing these ligands to form pivotal interactions with biological targets. In this context, the base-catalyzed Claisen-Schmidt condensation of 3',4'-(methylenedioxy)acetophenone with heteroaromatic aldehydes carrying an indole scaffold yielded new chalcones (-). The central and peripheral antinociceptive activities of all chalcones (compounds -) at the dose of 10 mg/kg (.) were evaluated by hot plate (supraspinal response), tail immersion (spinal response), and acetic acid-induced writhing tests in mice. The anti-inflammatory activities of compounds - were also investigated by means of a carrageenan-induced mouse paw edema model. The results revealed that compounds - extended the latency of response to thermal stimulus significantly in a hot-plate test similar to dipyrone (300 mg/kg; .), the positive control drug. However, only compounds - were found to be significantly effective in the tail-immersion test. Compounds - also significantly showed analgesic effect by reducing the number of writhes and anti-inflammatory activity by inhibiting edema formation at different time intervals and levels. 1-(1,3-Benzodioxol-5-yl)-3-(1-methyl-1-indol-2-yl)prop-2-en-1-one () drew attention by providing the highest efficacy results in both acute analgesia and inflammation models. Based on the data acquired from the QikProp module, compound was predicted to possess favorable oral bioavailability and drug-like properties. Taken together, it can be concluded that chalcones (-), especially compound , are outstanding candidates for further research to investigate their potential use in the management of pain and inflammation.

Inflammation is involved in the induction of chronic inflammatory and neuropathic pain. Moreover, the ketogenic diet, a high-fat, low-carbohydrate, and adequate protein diet, has an anti-inflammatory effect. Thus, we hypothesized that a ketogenic diet has a therapeutic effect on both types of chronic pain. In the present study, we investigated the effect of a ketogenic diet on mechanical allodynia, a chronic pain symptom, in formalin-induced chronic inflammatory pain and nerve injury-induced neuropathic pain models using adult male mice. Formalin injection into the hind paw induced mechanical allodynia in both the injected and intact hind paws, and the ketogenic diet alleviated mechanical allodynia in both hind paws. In addition, the ketogenic diet prevented formalin-induced edema. Furthermore, the diet alleviated mechanical allodynia induced by peripheral nerve injury. Thus, these findings indicate that a ketogenic diet has a therapeutic effect on chronic pain induced by inflammation and nerve injury.

Siponimod is a sphingosine 1-phosphate receptor (S1P) modulator used to treat secondary progressive multiple sclerosis (SPMS). We report 3 SPMS patients treated with siponimod who developed new or worsening peripheral oedema soon after commencing treatment. In one case, peripheral oedema resulted in immobility. Siponimod-related peripheral oedema deserves wider recognition due to the potential for morbidity and over-investigation. Clinicians should assess for pre-existing oedema and coexisting conditions that may predispose to developing peripheral oedema prior to commencing siponimod.
