INTRODUCTION ---Acute pericarditis is the most commonly encountered manifestation of pericardial disease (incidence: 0.2 percent to 0.5 percent in hospitalized patients). However, data regarding manifestations, workup, and the management of acute pericarditis in the African American population is lacking. This study aims to collect and analyze more clinical data related to acute pericarditis in this understudied population. METHODOLOGY We conducted a retrospective chart review of all patients managed for acute pericarditis at a university hospital serving a predominantly African American population...

BACKGROUND: Administration of topical 1:1000 epinephrine is commonly used in practice to achieve vasoconstriction during endoscopic sinus surgery and skull-base surgery; however, real-time effects on cardiovascular changes from systemic absorption have not been well studied. METHODS: Twenty-six patients undergoing endoscopic transsphenoidal resection of a pituitary lesion at a single institution were included into the study. Following arterial line placement by anesthesiology, 6 cottonoid pledgets soaked in 1:1000 epinephrine were placed into the bilateral nasal passages...

Airplane headache is a common problem with 100 million passengers annually suffering from the condition. It has been suggested that the changes in the cabin pressure during take-off and landing may cause inflammation in sinus tissues. This can lead to elevated levels of prostaglandin E2 and vasodilation of cerebral arteries resulting in airplane headache. Current evidence suggests opportunities to develop a treatment plan by examining future potential drugs for reducing the prostaglandin E2 level or preventing the vasodilation of the cerebral arteries...

Baseline assessment of functional stenosis severity has been proposed as a practical alternative to hyperemic indices. However, intact autoregulation mechanisms may affect intracoronary hemodynamics. The aim of this study was to investigate the effect of changes in aortic pressure (Pa) and heart rate (HR) on baseline coronary hemodynamics and functional stenosis assessment. In 15 patients (55 ± 3% diameter stenosis) Pa, intracoronary pressure (Pd) and flow velocity were obtained at control, and during atrial pacing at 120 bpm, increased Pa (+30 mmHg) with intravenous phenylephrine (PE), and elevated Pa while pacing at sinus heart rate (PE + sHR)...

The posterior maxilla is challenged with postextraction alveolar bone resorption and pneumatization drive of the Schneiderian membrane that reduces the subantral distance. To overcome such anatomic obstacle a sinus augmentation procedure was introduced either via lateral or crestal approach depending on residual ridge height. The current study evaluated oxidized regenerated cellulose (ORC) as a grafting material versus osteon II by measuring bone gain and graft density, 24 weeks postoperatively. Twenty consecutive patients (24 cases) aged from 20 to 65 years were considered eligible after clinical and radiographic evaluation...

An 11-year-old boy collapsed during morning assembly at his junior high school. The automated external defibrillator detected ventricular fibrillation and provided shock delivery. He was successfully resuscitated and reverted to sinus rhythm. Electrocardiography showed ST-T elevation in the precordial leads. Echocardiography and angiography demonstrated akinesia of the apex and mid-wall of the left ventricle with preserved contraction of the basal segments, which suggested Takotsubo cardiomyopathy. The patient and his family had often eaten uncooked crab, and his father had a past history of infection with Paragonimiasis westermani...

A 42-year-old male presented with a one-week history of palpitations and sweating episodes. The only significant history was of longstanding idiopathic dilated cardiomyopathy. Initial ECG demonstrated a sinus tachycardia. Thyroid function testing, undertaken as part of the diagnostic workup, revealed an un-measureable thyroid-stimulating hormone (TSH) and free thyroxine (T4). Upon questioning the patient reported classical thyrotoxic symptoms over the preceding weeks. Given the persistence of symptoms free tri-iodothyronine (T3) was measured and found to be markedly elevated at 48...

BACKGROUND: The anterior clinoid process shares a close relationship with the optic canal, the internal carotid artery, the superior orbital fissure and the cavernous sinus. These structures may be involved in diseases whose surgical exposure requires prior clinoid process resection. METHOD: Based on operative cases we describe the different steps of this surgical technique and illustrate our surgical procedure with a video. Dividing the orbito-temporal periosteal fold is a key-step in order to optimize the elevation of the periosteal dural layer at the level of the superior orbital fissure to expose the contours of the anterior clinoid process...

This case series study demonstrates the possibility of successful implant rehabilitation without bone augmentation in the atrophic posterior maxilla with cystic lesion in the sinus. Sinus lift without bone graft using the lateral approach was performed. In one patient, the cyst was aspirated and simultaneous implantation under local anesthesia was performed, whereas the other cyst was removed under general anesthesia, and the sinus membrane was elevated in a second process, followed by implantation. In both cases, tapered 11...

Young women with acute myocardial infarction (AMI) have a worse prognosis than their male counterparts. We searched for differences in the electrocardiographic presentation of men and women in a large, contemporary registry of young adults with AMI that could help explain gender differences in outcomes. The qualifying electrocardiogram was blindly assessed by a central core lab in 3,354 patients (67% women) aged 18 to 55 years included in the Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients study...

Osteotomes have long been used in the formation of osteotomies for the placement of dental implants. Their ability to manipulate and compress existing bone without generating heat makes them particularly useful for expanding narrow ridges, elevating delicate sinus membrane, and increasing relative bone density around the osteotomy. Common concerns with these devices include the traumatic force communicated to the patient during use and difficulty controlling force vectors. A new type of osteotome has been developed that is designed to enable the clinician to eliminate the concerns found with traditional osteotomes yet it preserves the best qualities and functionality of this class of device...

BACKGROUND: The Draf III approach to the frontal sinus can be used during revision endoscopic sinus surgery for chronic rhinosinusitis and to provide access for tumor resection, mucoceles, and repair of cerebrospinal fluid leaks. OBJECTIVE: To describe a simple and safe way to perform a Draf III approach by using the "outside-in" approach. METHODS: By using a 0° endoscope and a single 15°, 5-mm, coarse diamond burr, the main steps of the procedure are the following: (1) elevation of the mucosal flaps and creation of the septal window, (2) drilling out the frontal beak, (3) creation of neo-ostium and removal of the interfrontal septum, (4) joining the neo-ostium with the frontal recesses, (5) smoothing off the cavity and lowering of the "frontal T," and (6) use of mucosal flaps and grafts to cover exposed bone...

RATIONALE: Lymphomas take up about 14% of all head-neck malignancies, out of which 97% are non-Hodgkin lymphomas (NHL). The clinical courses, treatment responses, and prognoses of NHLs vary with different subtypes and anatomic sites. In the Chinese population (including the Taiwanese), head-neck NHLs are often seen with the tonsils, nasal cavity, nasal sinus, and the nasopharynx. However, oral NHLs are relatively rare. Delay of diagnosis is also often seen in clinical practice. Thus, we present 4 cases with delayed diagnosis of oral maxillofacial NHLs and discuss their clinical manifestations so as to draw a clue that can remind the doctors to take biopsies in time...

Over the years, the aVR lead has been overlooked by clinicians while observing a normal 12-lead ECG (electrocardiogram). A positive P-QRS complex in the aVR lead should raise prompt suspicion for either a congenital heart malrotation or a lead misplacement. In this article we present a case of an asymptomatic patient and a pathological ECG strip displaying ST elevations and a positive QRS in the aVR lead. A follow-up ECG was performed in the emergency department, and revealed a normal sinus rhythm with no abnormalities indicating acute ischemia...

Mesoporous bioactive glass (MBG) is a good scaffold for bone regeneration. In this study, amino functionalized MBG (N-MBG) was used as a model scaffold to examine the effect of the scaffold to bone marrow stromal cells (BMSCs) and macrophages. The MTT results revealed that the proliferation of BMSCs from ovariectomized rabbits was enhanced by N-MBG. Compared to the control group, the expression of osteogenic genes was significantly enhanced by N-MBG, which was related to CaSR pathway. Meanwhile, the anti-inflammatory cytokines (interleukin-10 and arginase-1) were also upregulated by N-MBG stimulation compared with MBG...
