Chart for Preparation of Dilutions of Alpha-Adrenergic Agonists for Intracavernous Use in Treatment of Priapism

Treatment of priapism with intracavernous alpha-adrenergic agonist vasoconstrictor agents is well accepted, particularly for patients with priapism secondary to intracavernous injections of papaverine, phentolamine and/or prostaglandin E1. Although many alpha-adrenergic agonists are commercially available, phenylephrine is preferred because it has potent and selective alpha1-adrenergic stimulatory properties, which can decrease arteriolar flow to the cavernous sinusoids, and no beta 1-stimulatory effect, which could cause arrhythmias and angina in susceptible patients. Before intracavernous injection or irrigation an alpha-adrenergic agonist must be diluted. However, no readily available reference source lists this information. Therefore, we prepared a chart for extemporaneous preparation of dilutions of alpha-adrenergic agonists for intermittent injection or irrigation.     

E-Cadherin/β-Catenin Complex: A Target for Anticancer and Antimetastasis Plants/Plant-derived Compounds

Plants reputed to have cancer-inhibiting potential and putative active components derived from those plants have emerged as an exciting new field in cancer study. Some of these compounds have cancer-inhibiting potential in different clinical staging levels, especially metastasis. A few of them which stabilize cell-cell adhesions are controversial topics. This review article introduces some effective herbal compounds that target E-cadherin/β-catenin protein complex. In this article, at first, we briefly review the structure and function of E-cadherin and β-catenin proteins, Wnt signaling pathway, and its target genes. Then, effective compounds of the Teucrium persicum, Teucrium polium, Allium sativum (garlic), Glycine max (soy), and Brassica oleracea (broccoli) plants, which influence stability and cellular localization of E-cadherin/β-catenin complex, were studied. Based on literature review, there are some compounds in these plants, including genistein of soy, sulforaphane of broccoli, organosulfur compounds of garlic, and the total extract of Teucrium genus that change the expression of variety of Wnt target genes such as MMPs, E-cadherin, p21, p53, c-myc, and cyclin D1. So they may induce cell-cycle arrest, apoptosis and/or inhibition of Epithelial-Mesenchymal Transition (EMT) and metastasis.     

Liver transplantation as a definitive treatment for familial hypercholesterolemia: A series of 36 cases

FH is a genetic disorder characterized by an increase in serum LDL and total cholesterol values. The afflicted patients are at increased risk of premature atherosclerosis and myocardial infarction. Different treatment modalities are present, including pharmacological agents and surgical procedures. The most effective method of therapy in refractive cases is liver transplantation. Herein, we report our experience on 36 cases of patients with FH undergoing liver transplantation in our center, the main referral center of liver transplantation in Iran. The clinical findings, hospital courses, post‐operative complications, and patient follow‐up are also described.     

Cognitive impairments in patients with cerebrovascular risk factors: A comparison of Mini Mental Status Exam and Montreal Cognitive Assessment

Objective and background

Recent evidence suggests that cerebrovascular risk factors are contributing factors, not only to vascular cognitive decline, but also for Alzheimer's disease. The study aim was to compare Montreal Cognitive Assessment (MoCA) and MMSE tests in subjects with cerebrovascular risk factors.

Patients and methods

Fifty patients with cerebrovascular risk factors were administrated the MMSE and MoCA tests. Data collected for all subjects and the results were compared.

Results

Cognitive impairments revealed on both tests were more frequent in females, and correlated with the level of education (for MoCA r = 0.75, p = 0.001 and for MMSE r = 0.662, p = 0.001). Mean values of MoCA score were significantly lower in patients with two or more cerebrovascular risk factors compared with those with only one risk factor (19.92 ± 5.99 versus 23.81 ± 4.06; p = 0.049), a finding that was not evidenced by MMSE.

Conclusions

The most frequent impaired domain in MMSE (for scores both less and more than 26) was attention; but in MoCA the most frequent impaired domains were delayed recall (for scores above 26), and visuo-executive (for scores ≤26), which is a common domain involved in vascular cognitive decline. MoCA may be superior to MMSE in early detection of cognitive decline in patients with vascular risk factors.
