Pesticide Residues in Vegetables and Fruits from Farmer Markets and Associated Dietary Risks.

The use of pesticides leads to an increase in agricultural production but also causes harmful effects on human health when excessively used. For safe consumption, pesticide residues should be below the maximum residual limits (MRLs). In this study, the residual levels of pesticides in vegetables and fruits collected from farmers' markets in Sharkia Governorate, Egypt were investigated using LC-MS/MS and GC-MS/MS. A total number of 40 pesticides were detected in the tested vegetable and fruit samples. Insecticides were the highest group in detection frequency with 85% and 69% appearance in vegetables and fruits, respectively. Cucumber and apple samples were found to have the highest number of pesticide residues. The mean residue levels ranged from 7 to 951 µg kg-1 (in vegetable samples) and from 8 to 775 µg kg-1 (in fruit samples). It was found that 35 (40.7%) out of 86 pesticide residues detected in vegetables and 35 (38.9%) out of 90 pesticide residues detected in fruits exceeded MRLs. Results for lambda-cyhalothrin, fipronil, dimothoate, and omethoate in spinach, zucchini, kaki, and strawberry, respectively, can cause acute or chronic risks when consumed at 0.1 and 0.2 kg day-1. Therefore, it is necessary for food safety and security to continuously monitor pesticide residues in fruits and vegetables in markets.

Association between left atrial appendage morphology evaluated by trans-esophageal echocardiography and ischemic cerebral stroke in patients with atrial fibrillation.

The left atrial appendage (LAA) represents one of the major sources of cardiac thrombi responsible for embolic stroke in patients with atrial fibrillation (AF). The aim of the present study was to evaluate LAA structure and functions by transesophageal echocardiography (TEE) in patients with AF to investigate the possible association between the different LAA morphologies and the patients' history of ischemic cerebral stroke. We included 50 patients with non-valvular AF (29 chronic, 21 paroxysmal), 24 patients (13 men) without stroke; and 26 patients (9 men) with a history of ischemic stroke. All patients underwent TEE evaluation of LAA morphology and functions. Compared to patients without stroke, patients with ischemic stroke had significantly higher CHADS2 scores (4.19 ± 0.89 versus 1.67 ± 1.13; P < 0.001) and C-reactive protein levels (8.3 ± 1.6 versus 7.6 ± 0.83 mg/L; P = 0.023), and lower peak filling (21.7 ± 11.3 versus 31.2 ± 9.5 cm/second; P = 0.033) and emptying (22.2 ± 9.7 versus 33.4 ± 13.4 cm/second, P = 0.030) velocities. Triangular LAA morphology had a higher prevalence in patients with stroke (36% versus 12% in non-stroke group); and in half of them an LAA thrombus was present. LAA thrombi were detected in 9 patients (18%) with stroke and in 5 patients (10%) without stroke. On multivariate logistic regression analysis, age (OR = 1.202 [1.042-1.585]; P = 0.041), LAA orifice diameter (OR = 1.275 [1.102-1.748]; P = 0.028), and triangular LAA morphology (OR = 4.53 [1.629-8.381]; P = 0.011) were significantly and independently associated with ischemic stroke in AF patients. LAA morphology evaluated by TEE may be useful for predicting ischemic cerebral stroke in patients with non-valvular AF, especially in those with a low CHADS2 score.

Targeting inflammatory signaling pathways with SGLT2 inhibitors: Insights into cardiovascular health and cardiac cell improvement.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors have attracted significant attention for their broader therapeutic impact beyond simply controlling blood sugar levels, particularly in their ability to influence inflammatory pathways. This review delves into the anti-inflammatory properties of SGLT2 inhibitors, with a specific focus on canagliflozin, empagliflozin, and dapagliflozin. One of the key mechanisms through which SGLT2 inhibitors exert their anti-inflammatory effects is by activating AMP-activated protein kinase (AMPK), a crucial regulator of both cellular energy balance and inflammation. Activation of AMPK by these inhibitors leads to the suppression of pro-inflammatory pathways and a decrease in inflammatory mediators. Notably, SGLT2 inhibitors have demonstrated the ability to inhibit the release of cytokines in an AMPK-dependent manner, underscoring their direct influence on inflammatory signaling. Beyond AMPK activation, SGLT2 inhibitors also modulate several other inflammatory pathways, including the NLRP3 inflammasome, expression of Toll-like receptor 4 (TLR-4), and activation of NF-κB (Nuclear factor kappa B). This multifaceted approach contributes to their efficacy in reducing inflammation and managing associated complications in conditions such as diabetes and cardiovascular disorders. Several human and animal studies provide support for the anti-inflammatory effects of SGLT2 inhibitors, demonstrating protective effects on various cardiac cells. Additionally, these inhibitors exhibit direct anti-inflammatory effects by modulating immune cells. Overall, SGLT2 inhibitors emerge as promising therapeutic agents for targeting inflammation in a range of pathological conditions. Further research, particularly focusing on the molecular-level pathways of inflammation, is necessary to fully understand their mechanisms of action and optimize their therapeutic potential in inflammatory diseases.

Exploring the cytoprotective role of mesenchymal stem Cell-Derived exosomes in chronic liver Fibrosis: Insights into the Nrf2/Keap1/p62 signaling pathway.

Hepatic fibrosis is a common pathology present in most chronic liver diseases. Autophagy is a lysosome-mediated intracellular catabolic and recycling process that plays an essential role in maintaining normal hepatic functions. Nuclear factor erythroid 2-like 2 (Nrf2) is a transcription factor responsible for the regulation of cellular anti-oxidative stress response. This study was designed to assess the cytoprotective effect of mesenchymal stem cell-derived exosomes (MSC-exos) on endothelial-mesenchymal transition (EMT) in Carbon Tetrachloride (CCL4) induced liver fibrosis. Rats were treated with 0.1 ml of CCL4 twice weekly for 8 weeks, followed by administration of a single dose of MSC-exos. Rats were then sacrificed after 4 weeks, and liver samples were collected for gene expression analyses, Western blot, histological studies, immunohistochemistry, and transmission electron microscopy. Our results showed that MSC-exos administration decreased collagen deposition, apoptosis, and inflammation. Exosomes modulate the Nrf2/Keap1/p62 pathway, restoring autophagy and Nrf2 levels through modulation of the non-canonical pathway of Nrf2/Keap1/p62. Additionally, MSC-exos regulated miR-153-3p, miR-27a, miR-144 and miRNA-34a expression. In conclusion, the present study shed light on MSC-exos as a cytoprotective agent against EMT and tumorigenesis in chronic liver inflammation.

Harnessing the power of bee venom for therapeutic and regenerative medical applications: an updated review.

Honeybees have been helpful insects since ancient centuries, and this benefit is not limited to being a honey producer only. After the bee stings a person, pain, and swelling occur in this place, due to the effects of bee venom (BV). This is not a poison in the total sense of the word because it has many benefits, and this is due to its composition being rich in proteins, peptides, enzymes, and other types of molecules in low concentrations that show promise in the treatment of numerous diseases and conditions. BV has also demonstrated positive effects against various cancers, antimicrobial activity, and wound healing versus the human immunodeficiency virus (HIV). Even though topical BV therapy is used to varying degrees among countries, localized swelling or itching are common side effects that may occur in some patients. This review provides an in-depth analysis of the complex chemical composition of BV, highlighting the diverse range of bioactive compounds and their therapeutic applications, which extend beyond the well-known anti-inflammatory and pain-relieving effects, showcasing the versatility of BV in modern medicine. A specific search strategy was followed across various databases; Web of sciences, Scopus, Medline, and Google Scholar including in vitro and in vivo clinical studies.to outline an overview of BV composition, methods to use, preparation requirements, and Individual consumption contraindications. Furthermore, this review addresses safety concerns and emerging approaches, such as the use of nanoparticles, to mitigate adverse effects, demonstrating a balanced and holistic perspective. Importantly, the review also incorporates historical context and traditional uses, as well as a unique focus on veterinary applications, setting it apart from previous works and providing a valuable resource for researchers and practitioners in the field.

Challenges of therapeutic applications and regenerative capacities of urine based stem cells in oral, and maxillofacial reconstruction.

Urine-derived stem cells (USCs) have gained the attention of researchers in the biomedical field in the past few years . Regarding the several varieties of cells that have been used for this purpose, USCs have demonstrated mesenchymal stem cell-like properties, such as differentiation and immunomodulation.

This review will embark on describing their separation, and profiling. We will specifically describe the USCs characteristics, in addition to their differentiation potential. Then, we will introduce and explore the primary uses of USCs. These involve thier utilization as a platform to produce stem cells, however, we shall concentrate on the utilization of USCs for therapeutic, and regenerative orofacial applications, providing an in-depth evaluation of this purpose. The final portion will address the limitations and challenges of their implementation in regenerative dentistry.

Bioactive injectable mucoadhesive thermosensitive natural polymeric hydrogels for oral bone and periodontal regeneration.

Periodontitis is an inflammation-related condition, caused by an infectious microbiome and host defense that causes damage to periodontium. The natural processes of the mouth, like saliva production and eating, significantly diminish therapeutic medication residency in the region of periodontal disease. Furthermore, the complexity and diversity of pathological mechanisms make successful periodontitis treatment challenging. As a result, developing enhanced local drug delivery technologies and logical therapy procedures provides the foundation for effective periodontitis treatment. Being biocompatible, biodegradable, and easily administered to the periodontal tissues, hydrogels have sparked substantial an intense curiosity in the discipline of periodontal therapy. The primary objective of hydrogel research has changed in recent years to intelligent thermosensitive hydrogels, that involve local adjustable sol-gel transformations and regulate medication release in reaction to temperature, we present a thorough introduction to the creation and efficient construction of new intelligent thermosensitive hydrogels for periodontal regeneration. We also address cutting-edge smart hydrogel treatment options based on periodontitis pathophysiology. Furthermore, the problems and prospective study objectives are reviewed, with a focus on establishing effective hydrogel delivery methods and prospective clinical applications.

Alchemilla vulgaris modulates isoproterenol-induced cardiotoxicity: interplay of oxidative stress, inflammation, autophagy, and apoptosis.

Introduction: Isoproterenol (ISO) is regarded as an adrenergic non-selective ß agonist. It regulates myocardial contractility and may cause damage to cardiac tissues. Alchemilla vulgaris (AV) is an herbal plant that has garnered considerable attention due to its anti-inflammatory and antioxidant bioactive components. The present investigation assessed the cardioprotective potential of AV towards ISO-induced myocardial damage. Methods: Four groups of mice were utilized: control that received saline, an ISO group (85 mg/kg, S.C.), ISO + AV100, and ISO + AV200 groups (mice received 100 or 200 mg/kg AV orally along with ISO). Results and discussion: ISO induced notable cardiac damage demonstrated by clear histopathological disruption and alterations in biochemical parameters. Intriguingly, AV treatment mitigates ISO provoked oxidative stress elucidated by a substantial enhancement in superoxide dismutase (SOD) and catalase (CAT) activities and reduced glutathione (GSH) content, as well as a considerable reduction in malondialdehyde (MDA) concentrations. In addition, notable downregulation of inflammatory biomarkers (IL-1ß, TNF-α, and RAGE) and the NF-κB/p65 pathway was observed in ISO-exposed animals following AV treatment. Furthermore, the pro-apoptotic marker Bax was downregulated together with autophagy markers Beclin1 and LC3 with in ISO-exposed animals when treated with AV. Pre-treatment with AV significantly alleviated ISO-induced cardiac damage in a dose related manner, possibly due to their antioxidant and anti-inflammatory properties. Interestingly, when AV was given at higher doses, a remarkable restoration of ISO-induced cardiac injury was revealed.

A novel technique for multi-track percutaneous balloon mitral valvoplasty.

Percutaneous balloon mitral valvoplasty (PBMV) has become the treatment of choice for severe pliable rheumatic mitral stenosis. The multi-track system is a recent variation of the double-balloon technique and is easier owing to the use of a monorail balloon and a simple, single-guidewire approach. In the present study, we used the double-coil Inoue metal wire with a multi-track balloon instead of the conventional multi-track wire. We studied 62 consecutive patients (55 females) with significant symptomatic rheumatic mitral valve stenosis who underwent multi-track PBMV. Patients were randomized into 2 groups: the first group included 32 patients treated with the novel multi-track technique using the double-coil Inoue metal wire, and the second group included 30 patients treated with the conventional multi-track technique using a balloon endhole catheter and multi-track 0.035 inch stiff wire. None of the patients had cardiac tamponade, systemic thromboembolism, or any groin complications. No statistically significant differences were found between the 2 groups regarding any of the studied variables. There were no in-hospital deaths or complications necessitating emergent cardiac surgery in either group. In conclusion, this new technique with the double-coil Inoue metal wire achieves the double benefit of being as safe as (and indeed easier than) the conventional technique, and it utilizes fewer materials, making the multi-track system more cost-effective.

Force-frequency relationship as a predictor of long-term prognosis in patients with heart diseases.

Adequate evaluation of the nature of the residual failing myocardium, as well as the severity of myocardial injury, is important for managing patients with heart failure. The aim of this study was to investigate the myocardial function and the prognosis of patients with heart diseases using the force-frequency relationship (FFR). We enrolled 76 patients with sinus rhythm who had miscellaneous heart diseases and performed incremental right atrial pacing at the time of diagnostic cardiac catheterization. The first derivatives of left ventricular pressure (dP/dt) were recorded using a micro manometer-tipped catheter during the study. To represent properties of FFR, two parameters-the peak force rate (PFR) and force gain (FG)-were estimated. PFR was defined as the heart rate at which dP/dt became maximum. FG was defined as the difference between dP/dt at PFR and dP/dt at the basal heart rate. FG decreased as the severity of left ventricular (LV) dysfunction increased (372.0 ± 110.7, 209.5 ± 29.1 and 116.3 ± 13.1 mmHg/s for normal LV function, mild LV dysfunction and severe LV dysfunction groups, P < 0.05, respectively). PFR correlated with cardiac index (r = 0.375, P = 0.001). FG correlated with LV end systolic volume index (r = -0.297, P = 0.010) and LV ejection fraction (r = 0.539, P < 0.001). Furthermore, pulmonary arterial wedge pressure [hazard ratio (HR) 1.126, P < 0.01] and FG (HR 0.992, P = 0.061) tended to be independent predictors for cardiovascular death. Analysis of FFR, especially FG, seems to be useful to evaluate the nature of the failing myocardium and the prognosis of patients with heart diseases.

Insulin-Induced Edema in a Patient with Type 2 Diabetes Mellitus.

BACKGROUND The strong association between type 2 diabetes and obesity has been well recognized. Insulin treatment is usually needed at some point in the treatment of patients with type 2 diabetes and obesity to achieve the targeted glycemic control goal. CASE REPORT A 35-year-old woman who had gastric banding for morbid obesity 1 year prior presented to the outpatient clinic with recent onset of shortness of breath and bilateral ankle edema, which were thought to be of cardiac origin. Band slippage occurred a few months after the procedure, and the patient gained weight rapidly thereafter. She had been diagnosed with type 2 diabetes mellitus 8 years earlier, which was treated with oral hypoglycemic medication. Thyroid function tests done 4 months prior to her current presentation revealed normal results. A cardiac assessment showed normal cardiac function with no evidence of heart failure. Repeated thyroid function testing showed new-onset subclinical hypothyroidism. The patient had started insulin therapy 2 weeks before her current presentation, which was probably the main cause of her edema. While continuing insulin, the patient's general condition improved with diuretics therapy, following which she had gastric bypass surgery. CONCLUSIONS Insulin-induced edema is an under-diagnosed problem. It should be considered whenever a patient with uncontrolled diabetes develops rapid body swelling after initiation of insulin therapy. Rigorous research is needed to explore the pathophysiology, prevalence, and treatment of insulin-induced edema.

Polyphenolic extracts from pomegranate and watermelon wastes as substrate to fabricate sustainable silver nanoparticles with larvicidal effect against Spodoptera littoralis.

The agricultural wastes adversely affect the environment; however, they are rich in polyphenols; therefore, this study aimed to employ polyphenol-enriched waste extracts for silver nanoparticles synthesis, and study the larvicidal activity of silver nanoparticles fabricated by pomegranate and watermelon peels extracts (PPAgNPs and WPAgNPs) against all larval instars of Spodoptera littoralis. The polyphenol profile of pomegranate and watermelon peel extracts (PP and WP) and silver nanoparticles was detected by HPLC. The antioxidant activity was estimated by DPPH, and FARP assays and the antimicrobial activity was evaluated by disc assay. The Larvicidal activity of AgNPs against Egyptian leaf worm was performed by dipping technique. The obtained AgNPs were spherical with size ranged 15-85 nm and capped with proteins and polyphenols. The phenolic compounds in silver nanoparticles increased about extracts; therefore, they have the best performance in antioxidant/reducing activity, and inhibit the growth of tested bacteria and yeast. The PPAgNPs were the most effective against the first instar larvae instar (LC50 = 68.32 µg/ml), followed by pomegranate extract with (LC50 = 2852 µg/ml). The results indicated that obvious increase in polyphenols content in silver nanoparticles enhance their larvicidal effect and increasing mortality of 1st larval of S. littoralis Egyptian leafworms causing additive effect and synergism. We recommend recycling phenolic enriched agricultural wastes in producing green silver nanoprticles to control cotton leafworm that causes economic loses to crops.

Evaluation of channel function after alteration of amino acid residues at the pore center of KCNQ1 channel.

The effect of the electrical charge or the size of the amino acid residue at the pore center of a slowly activation component of the delayed rectifier potassium channel: KCNQ1 was studied. K(+) currents were measured after transfection of one of four KCNQ1 mutants: substituting Isoleucine with Lysine, Glutamate, Valine or Glycine and then transfected in COS-7 cells. Both the negatively- and positive charged residue I313K and I313E showed a loss of function when expressed alone and a dominant negative suppression when co-expressed with wild type KCNQ1. When the site was substituted with the smallest neutral amino acid residue: I313G, there was a small reduction of current when transfected alone and a gain of function when co-transfected with the wild type. I313V showed no difference from the wild type. Changes of amino acid residue at the pore center of KCNQ1 may alter the channel function but this depends on the electrical charge or the size of amino acid residue.

A double-point mutation in the selectivity filter site of the KCNQ1 potassium channel results in a severe phenotype, LQT1, of long QT syndrome.

INTRODUCTION: Slowly activating delayed-rectifier potassium currents in the heart are produced by a complex protein with alpha and beta subunits composed of the potassium voltage-gated channel KQT-like subfamily, member 1 (KCNQ1) and the potassium voltage-gated channel Isk-related family, member 1 (KCNE1), respectively. Mutations in KCNQ1 underlie the most common type of hereditary long QT syndrome (LQTS). Like other potassium channels, KCNQ1 has six transmembrane domains and a highly conserved potassium selectivity filter in the pore helix called "the signature sequence." We aimed to investigate the functional consequences of a newly identified mutation within the signature sequence. METHODS AND RESULTS: Potassium channel genomic DNA from a family with clinical evidence of LQTS was amplified by polymerase chain reaction (PCR), and the resulting products were then sequenced. Three family members had a double-point mutation in KCNQ1 at nucleotides 938 (T-to-A) and 939 (C-to-A), resulting in an isoleucine-to-lysine change at amino acid position 313. These patients displayed prolonged QTc intervals (629, 508, and 500 ms(1/2,) respectively) and repetitive episodes of syncope, but no deafness. Three-dimensional structure modeling of KCNQ1 revealed that this mutation is located at the center of the channel pore. COS-7 cells displayed a lack of current when transfected with a plasmid expressing the mutant. In addition, the mutant displayed a dominant negative effect on current but appeared normal with respect to plasma membrane integration. CONCLUSION: An I313K mutation within the selectivity filter of KCNQ1 results in a dominant-negative loss of channel function, leading to a long QT interval and subsequent syncope.

Serum endostatin in the coronary circulation of patients with coronary heart disease and its relation to coronary collateral formation.

The role of endostatin in coronary heart disease (CHD) is not well known. This study aimed to investigate the dynamics of endostatin, an antiangiogenic growth factor, within the coronary circulation and to elucidate its relation to coronary collateral formation in patients with CHD. We recruited 72 subjects with suspected or previously diagnosed CHD. Blood samples from the left ventricular (LV) cavity and coronary sinus (CS) were obtained during coronary angiography, and the serum concentration of endostatin was measured by enzyme-linked immunosorbent assay kits. Patients were then divided into 2 groups: the normal group (n = 15) defined as patients with atypical chest pain and no evidence of organic cardiac diseases and the CHD group (n = 57) defined as patients with >or=75% coronary stenosis at coronary angiography and chest pain on exertion. Endostatin in CS sera was significantly elevated in patients with CHD compared with normal subjects (median 79.7 [interquartile range 46.2 to 130.3] vs median 49.6 [interquartile range 29.1 to 84.5] ng/ml, p = 0.02). Spillover of endostatin (CS - LV value) from the coronary circulation in patients with CHD with severe stenosis was higher than in those with moderate stenosis (28.2 [4.8 to 48.6] vs 7.3 [-37.0 to 25.6] ng/ml, p = 0.01). In addition, endostatin production within the coronary circulation was higher in patients with poorly developed collaterals than in those with well-developed collaterals. In conclusion, endostatin is suggested to be produced from the coronary circulation in patients with CHD and may play an important role in the regulation of the growth of coronary collateral vessels.

Toll-like receptor-2 Arg753Gln and Arg677Trp polymorphisms and susceptibility to pulmonary and peritoneal tuberculosis.

Recent evidence suggests that toll-like receptor-2 (TLR2) is important for host defense against Mycobacterium tuberculosis (MTB). TLR2 polymorphisms have shown significant impact on susceptibility or resistance to tuberculosis (TB). This case-control study aims to determine the influence of TLR2 (Arg753Gln and Arg677Trp) polymorphisms on the susceptibility to develop pulmonary or peritoneal TB. Genotyping of TLR2 (Arg753Gln and Arg677Trp) polymorphisms was carried out on 52 patients with pulmonary TB, 44 patients with peritoneal TB, and 50 healthy controls using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). There was a significant association between the GA genotype (heterozygous mutant) of TLR2 Arg753Gln polymorphism and the risk of infection with pulmonary TB (p = 0.003, OR = 4.83) and TB peritonitis (p = 0.003, OR = 6.2). Differences in the genotype frequencies of TLR2 Arg677Trp polymorphisms between patients with pulmonary or peritoneal TB and healthy controls were not detected. GA753 TLR2 polymorphism may play a role in the susceptibility to pulmonary and peritoneal TB infection. Further studies on a large number of ethnically diverse patient cohorts may help to confirm the possible effect of these polymorphisms on the susceptibility to pulmonary and peritoneal TB.

Impact of percutaneous coronary intervention on the levels of interleukin-6 and C-reactive protein in the coronary circulation of subjects with coronary artery disease.

Many clinical studies have evaluated the inflammatory response (mainly interleukin [IL]-6 and C-reactive protein [CRP]) after percutaneous coronary intervention (PCI) in patients with coronary artery disease (CAD). The aim of this study was to verify the source of possible elevation of IL-6 and CRP after PCI using coronary sinus sampling. We studied 87 subjects who underwent coronary angiography for diagnostic, therapeutic, or follow-up purposes. Blood samples were taken by the PCI team during the catheterization study from the coronary sinus. We measured coronary IL-6 levels by sandwich enzyme-linked immunosorbent assay, and high-sensitivity CRP levels were measured by latex immunonephelometry. The subjects were then classified according to their coronary angiographic findings into non-CAD (no evidence of significant organic CAD), mild CAD (1 vessel narrowed), and severe CAD (>or=2 vessels narrowed) groups. PCI (including stent deployment) was performed in 16 patients with CAD. The mean coronary IL-6 value was higher in the severe than in the mild CAD group (3.67 +/- 2.48 vs 2.3 +/- 1.15 pg/ml, p = 0.027). The mean coronary IL-6 value was higher in the subjects who underwent PCI than in those who did not (2.9 +/- 1.23 vs 1.87 +/- 0.9 pg/ml, p = 0.037), and the same was found regarding CRP (1.244 +/- 0.72 vs 0.498 +/- 0.51 mg/L, p = 0.032). The coronary IL-6 values correlated positively with the coronary CRP values (r = 0.374, p = 0.017). In conclusion, the increase in coronary IL-6 and CRP levels after PCI in patients with CAD might be attributed to their release from the coronary atheroma secondary to the direct mechanical effect applied on the atheroma itself by balloon inflation and stent deployment.

Noncomplicated Excision of a Mobile Pedunculated Septal Hemangioma of the Left Ventricle.

BACKGROUND Cardiac tumors are quite rare, and differential diagnosis of them is challenging. CASE REPORT A young lady with a history of palpitations, dyspnea, and fatigue was proven by transthoracic echocardiography and cardiac magnetic resonance imaging to have a mobile left ventricular mass with rounded contour attached to the mid-part of the interventricular septum. The mass was approached via a posterior inter-atrial approach to avoid left ventriculotomy and provide adequate exposure to completely excise the tumor and control its pedicle with minimal cardiac trauma. Histological examination of the mass was diagnostic of capillary and sinusoidal hemangioma. CONCLUSIONS Complete excision of cardiac hemangioma is recommended once it is diagnosed, for histopathologic diagnosis and because of the possibility of serious complications.

A huge thrombosed pulmonary artery aneurysm without pulmonary hypertension in a patient with hepatosplenic schistosomiasis.

BACKGROUND: We herein report a case of huge pulmonary artery aneurysm in a 55-year-old male farmer from the Nile delta (Lower-Egypt), mostly due to infestation with Schistosoma mansoni, which is the parasite causing hepatosplenic schistosomiasis. CASE REPORT: This male patient was admitted with a month-long history of progressive shortness of breath, 2-month history of fever, and a cough with mucoid sputum for 10 days. On examination, he had normal temperature and blood pressure, but he had tachypnea, tachycardia, and congested neck veins. Electrocardiography showed multifocal atrial tachycardia and right bundle branch block. CONCLUSIONS: The present case is unique in that it shows the presence of a huge pulmonary artery aneurysm despite the absence of pulmonary hypertension.
