We aimed to clarify the relationship between intra- and peri-organ fat, visceral fat, and subcutaneous fat. We used abdominal CT to evaluate intra- and peri-organ fat accumulations in the pancreas, liver, spleen, renal parenchyma, renal sinus, and skeletal muscle. The relationships between these fats, visceral fat, and subcutaneous fat were examined by using the partial correlation and covariance analysis, adjusting for BMI. We found that visceral fat and each intraand peri-organ fat accumulation were positively correlated, whereas subcutaneous fat and the accumulation of each intra- and peri-organ fat and visceral fat were negatively correlated...

PURPOSE OF REVIEW: More than a century since its discovery, the pathogenesis of Chagas heart disease (CHD) remains incompletely understood. The role of derangements in the autonomic control of the heart in triggering malignant arrhythmia before the appearance of contractile ventricular impairment was reviewed. RECENT FINDINGS: Although previous investigations had demonstrated the anatomical and functional consequences of parasympathetic dysautonomia upon the heart rate control, only recently, coronary microvascular disturbances and sympathetic denervation at the ventricular level have been reported in patients and experimental models of CHD, exploring with nuclear medicine methods their impact on the progression of myocardial dysfunction and cardiac arrhythmias...

Background: Chondrosarcomas are slow-growing malignant tumors that originate in cartilaginous structures. They typically manifest in the head and neck region, with a preference for the maxillofacial skeleton, particularly the mandible and maxilla. However, chondrosarcoma of the sinonasal tract is exceptionally rare, and only few cases have been reported. Case Presentation: This report details the case of a 43-year-old woman who incidentally discovered chondrosarcoma in the maxillary and ethmoid sinuses with nasal extension...

Pharmacokinetics studies of anesthetic agents are important for understanding of the pharmacology and metabolism of anesthetic agents in reptilians. This study was designed to examine the pharmacokinetic and pharmacodynamic properties of intravenous dextroketamine alone or combined with midazolam in Caiman crocodilus. Eight caimans were anesthetized with dextroketamine (10 mg/kg; group D) or dextroketamine and midazolam (10 and 0.5 mg/kg respectively; group DM) into the occipital venous sinus...

This study evaluated the immediate and 1-year postoperative outcomes of 14 patients with ruptured Valsalva aneurysmal sinus (RSVA) using symmetric ventricular septal defect (VSD) occluder for transcatheter closure (TCC). The sites of rupture were from the non-coronary sinus to the right atrium (RA) in 10 cases (71.4%), the right coronary sinus (RCS) to the RA in 3 cases (21.4%) and the RCS to the right ventricle in 1 case (7.2%). The defects (5-11 mm) were closed with a symmetrical VSD device. During the follow-up (12 months), the enlarged heart of the patients had significantly shrunk and the NYHA improved after closure...

We describe a case of rhino-orbital-cerebral mucormycosis (ROCM) in a diabetic patient. She presented with cavernous sinus syndrome and ischemia of the optic nerve. Initially unremarkable findings in the nasal cavity and paranasal sinus delayed early diagnosis. Within two weeks, a follow-up MRI showing progressive orbital inflammation, thrombosis of the cavernous sinus and erosive destruction of the left middle nasal concha together with necrotic black tissue in the left nasal cavity and destruction of the maxillary sinus demonstrated in a consecutively performed ethmoidectomy, finally gave way to diagnosis...

BACKGROUND: Septic cavernous sinus thrombosis (CST) is a rare condition traditionally associated with high morbidity and mortality. More recent case series report more favorable outcomes, including full functional recovery. A comprehensive assessment of the clinical characteristics and prognostic factors of visual and survival outcomes in septic CST is warranted to contemporize current understanding and help guide management. METHODS: A multicentered retrospective cohort study was conducted at 2 tertiary care centers using an electronic medical record search of the term, "thrombosis of cavernous venous sinus" between January 1, 2000, and December 31, 2021...

BACKGROUND: Gastric intramural hematoma is a rare disease. Here we report a case of spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma. CASE PRESENTATION: A 75-years-old man was admitted to our department with complaints of abdominal pain. He underwent a whole abdominal computed tomography (CT) scan in the emergency department, which showed extensive thickening of the gastric wall in the gastric body and sinus region with enlarged surrounding lymph nodes, localized thickening of the intestinal wall in the transverse colon, localized indistinct demarcation between the stomach and transverse colon, and a small amount of fluid accumulation in the abdominal cavity...

The aim of this retrospective study was to assess the efficacy of recombinant human bone morphogenetic protein-2 (rhBMP-2) with hydroxyapatite (HA) granules and fibrin sealant (FS) in maxillary sinus floor augmentation (MSFA), with a focus on the volume change. Fifty-two of 137 patients who underwent MSFA with rhBMP-2/HA grafting between June 2016 and December 2022 met the study inclusion criteria; 25 had received rhBMP-2/HA without FS and 27 had received rhBMP-2/HA with FS. Computed tomography (CT) images were obtained preoperatively, immediately following the operation, and at 6 months postoperative...

The present research aimed to document the incidence, clinical signs, haematological, and serum biochemical alterations, as well as electrocardiography and echocardiography findings in 62 buffaloes (selected from a total of 240) infected with Trypanosoma evansi. The study spanned one year, from January 2022 to December 2022. Morphological identification of Trypanosoma evansi was done by the presence of a centrally positioned nucleus with a small sub-terminal kinetoplast at the posterior position through microscopic examination of Giemsa stained peripheral blood smears...

To enhance M-mode echocardiography's utility for measuring cardiac structures, we developed and evaluated an artificial intelligence (AI)-based automated analysis system for M-mode images through the aorta and left atrium [M-mode (Ao-LA)], and through the left ventricle [M-mode (LV)]. Our system, integrating two deep neural networks (DNN) for view classification and image segmentation, alongside an auto-measurement algorithm, was developed using 5,958 M-mode images [3,258 M-mode (LA-Ao), and 2,700 M-mode (LV)] drawn from a nationwide echocardiographic dataset collated from five tertiary hospitals...

PURPOSE: Office-based rhinologic procedures (OBRP) have become widely available in North America due to technological advances and appropriate patient selection. Nevertheless, the literature exploring the safety of these procedures remains limited. The objective of this study was to further evaluate the safety, tolerability and efficacy of these procedures with a more robust sample size to allow for capture of rare events. METHODS: A retrospective chart review of all patients who underwent OBRP from May 2015 to March 2023...

Anatomical variations are a common feature of the human anatomy. Variation can explain some pathological conditions and is important to keep them in mind during surgical procedures. The relations between nerves and their adjacent arteries have been proposed to play a role in the generation of peripheral trigger migraines. Close opposition between nerves and arteries can lead to vascular compression of the nerve that triggers episodes of pain. We did a routine dissection of the infratemporal fossa and orbital floor by opening the maxillary sinus...

Topical budesonide irrigations are frequently prescribed after endoscopic sinus surgery (ESS) to manage mucosal inflammation. However, this off-label indication may conflict with health insurance formularies. We sought to quantify the relative frequency of postoperative budesonide prescriptions to determine if this could be considered common practice after ESS. We extracted and analyzed postoperative prescription data for patients undergoing ESS from 2016 to 2022 within our health care system. Overall, among 8157 ESS patients, 15...

Acute invasive fungal sinusitis (AIFS) classically presents as an aggressive fungal infection that can spread beyond its origin in the sinuses in immunocompromised patients. Although there have been reports of AIFS in immunocompetent, non-diabetic patients, it is extremely rare and the true mechanism behind it is unknown. A thirty-eight year old immunocompetent, non-diabetic woman underwent bilateral ESS for chronic rhinosinusitis with nasal polyps at a tertiary care center and post-operatively developed AIFS...

OBJECTIVE: Endoscopic endonasal surgery is effective in the treatment of sinonasal cancers. However, in cases of well-differentiated locally advanced neoplasms as well as recurrences, the most appropriate treatment is debated. The purpose of this study is to report a mono-institutional experience on craniofacial surgery performed in a tertiary-care referral centre. METHODS: This was a retrospective analysis of 90 patients treated with transcranial and/or transfacial resection for sinonasal cancer between 2010 and 2020...

BACKGROUND: We aimed to analyze the impact of concomitant Maze procedure on the clinical and rhythm outcomes, and echocardiographic parameters in tricuspid repair for patients with severe tricuspid regurgitation (TR) and persistent atrial fibrillation (AF). METHODS: Patients who had severe TR and persistent AF and underwent tricuspid valve (TV) repair were included in the study. Both primary TR and secondary TR were included in the current study. The study population was stratified according to Maze procedure...

BACKGROUND: No standardized criteria for surgical resection of parasagittal sinus meningiomas (PSM) have been established, and different surgical strategies have been proposed. The aim of the present study was to investigate the efficacy and safety of a "radical" surgical strategy in the treatment of PSM. METHODS: The clinical histories, radiological findings, pathologic features, and surgical records of 53 patients with PSM admitted by the same surgical team using the "radical" surgical strategy were retrospectively analyzed between 2018 and 2023...
