An Apical Mass of the Left Ventricle After a Myocardial Infarction: Imaging Contribution

Intramyocardial dissecting hematoma (IDH) is a rare complication of myocardial infarction (MI). It can affect the left ventricular free wall, the right ventricle, or the interventricular septum. We report a case of a 58-year-old man with an IDH following an acute anterior wall myocardial infarction detected by echocardiography and confirmed by Cardiac magnetic resonance (CMR).     

Association of PTPN22 gene polymorphism and systemic lupus erythematosus in a cohort of Egyptian patients: impact on clinical and laboratory results

To assess the possible association between the protein tyrosine phosphatases non-receptor 22 (PTPN22) gene 1858 CT polymorphism and the predisposition to systemic lupus erythematosus (SLE) in Egyptian patients and its influence on clinical and laboratory parameters. PTPN22 gene 1858 CT polymorphisms were analyzed in forty SLE patients and 20 normal controls by real-time polymerase chain reaction (PCR) technology, using the TaqMan 5-allele discrimination assay. Detailed history, clinical examination, and investigations were done to detect various organ involvement. The homozygous genotype TT was absent in both SLE and controls. The CC genotype was observed in 47.5% SLE and 80% controls; the CT genotype was found in 52.5% patients and 20% controls. The frequencies of the C and T alleles were 74 and 26% in SLE and 90 and 10% in controls, respectively. The presence of CT genotype increased the risk for developing SLE by 4.42. Renal involvement was significantly higher in SLE patients with CT (76.2%) compared to those with CC genotype (42.1%).     

Impact of garlic feeding (Allium sativum) on male fertility

Many medicinal plants are designed to improve health but their mechanism of action remains not clear. Among these plants, garlic (Allium sativum) has attracted particular attention of modern medicine because of its widespread use for the prevention and treatment of some human diseases such as cardiovascular diseases and cancer. However, the impact of garlic on the male reproductive system has not been clearly defined. Some studies have reported that garlic improves male sexual function and has beneficial effect in the recovery of testicular functions. However, other authors have shown that this plant impairs testicular functions (such as inhibition of testosterone production) and has spermicidal effect on spermatozoa. In this review, we attempt to clarify the current ambiguity regarding the effects of garlic and its preparations on the male reproductive system.     

Tacrolimus ameliorates functional disturbances and oxidative stress in isoproterenol-induced myocardial infarction

Background

The inflammatory responses play a major role in the pathogenesis of acute myocardial infarction (MI). Early inhibition of inflammation may improve post MI cardiac function. The aim of this study was to investigate the effects of tacrolimus on cardiac function, hemodynamic parameters as well as histopathologic and electrocardiographic changes in isoproterenol-induced myocardial infarction.

Methods

Male Wistar rats were randomly divided into six groups of control, isoproterenol alone, tacrolimus alone, and isoproterenol plus tacrolimus (0.5, 1 and 2 mg/kg). Isoproterenol (100 mg/kg) was injected subcutaneously for two consecutive days to induce myocardial infarction, and simultaneously tacrolimus was administered orally twice a day for three days.

Results and conclusions

Administration of isoproterenol resulted in myocardial edema and necrosis as well as a marked reduction in the left ventricular systolic pressure (LVSP), left ventricular contractility (LVdP/dt_max) and relaxation (LVdP/dt_min) along with a severe elevation in left ventricular end-diastolic pressure (LVEDP). Isoproterenol also elevated the ST-segment and suppressed the R-amplitude and R-R interval on ECG. It was found that all doses of tacrolimus could amend the ECG pattern and ameliorated the isoproterenol induced disturbances in cardiac function. Acute and short term treatment with tacrolimus at dose of 2 mg/kg significantly (P < 0.001) improved LVdP/dt_max from 2712 ± 82 in myocardial infarcted rats to 4592 ± 149 mmHg/sec. Similarly, tacrolimus lowered LVEDP from 17.6 ± 0.68 in MI group to the value of 5.6 ± 0.22 mmHg (P < 0.001). Furthermore, tacrolimus was found to reduce malondialdehyde concentration in serum and myocardium by 50-70% (P < 0.001).The results of this study showed that acute treatment with tacrolimus, coincided with the occurrence of myocardial infarction, strongly protected the myocardium against the isoproterenol-induced myocardial infarction; where this might be due to the anti-inflammatory properties of tacrolimus.     

Pigmented and polypoid tumor of the pubis

Seborrheic keratosis is a common benign epidermal tumor occurring in patients aged over 50 years. It is located preferentially in the trunk, head and neck. The genital location is rare. We report a case of 59 year‐old‐men presenting a seborrheic keratosis of the pubis.     

Saffron (Crocus sativus L.): A Source of Nutrients for Health and for the Treatment of Neuropsychiatric and Age-Related Diseases

Saffron (Crocus sativus L.) is a medicinal plant, originally cultivated in the East and Middle East, and later in some Mediterranean countries. Saffron is obtained from the stigmas of the plant. Currently, the use of saffron is undergoing a revival. The medicinal virtues of saffron, its culinary use and its high added value have led to the clarification of its phytochemical profile and its biological and therapeutic characteristics. Saffron is rich in carotenoids and terpenes. The major products of saffron are crocins and crocetin (carotenoids) deriving from zeaxanthin, pirocrocin and safranal, which give it its taste and aroma, respectively. Saffron and its major compounds have powerful antioxidant and anti-inflammatory properties in vitro and in vivo. Anti-tumor properties have also been described. The goal of this review is to present the beneficial effects of saffron and its main constituent molecules on neuropsychiatric diseases (depression, anxiety and schizophrenia) as well as on the most frequent age-related diseases (cardiovascular, ocular and neurodegenerative diseases, as well as sarcopenia). Overall, the phytochemical profile of saffron confers many beneficial virtues on human health and, in particular, on the prevention of age-related diseases, which is a major asset reinforcing the interest for this medicinal plant.
