Abstract

Background: Erectile dysfunction is an important problem in men and an organic cause is found in about 50% of cases. When a vasculogenic etiology is suspected, imaging assessments are of great help. Cavernosography is traditionally recognized as an imaging modality for evaluation of venous leakage in men with impotency. We employed CT cavernosography as a novel technique for demonstrating penile venous anatomy and leaking veins.
Methods: In the present case series study, we recruited 45 patients with erectile dysfunction by convenient sampling at Hazrat Rasoul Akram Hospital in Tehran, Iran, during one year (1390). The patients had previously been diagnosed with venous incompetency by Doppler study. After intracavernosal injection of prostaglandin E1, we injected sterile normal saline into the corpora cavernosa to achieve penile erection. Later, we injected contrast media into the corpus cavernosum, which was followed by CT scan of the penis and pelvic area to show the venous anatomy and leakage sites.
Results: The mean age of the patients was 35.8±8.9 years. 36 (80%) patients had venous leakage in crural veins, 27 (60%) in cavernosal veins, 27 (60%) in circumflex veins, 24 (52.3%) in urethral veins, 21 (46.7%) in deep dorsal vein, 3 (6.7%) in para-arterial veins and 3 (6.7%) in corpus spongiosum.
Conclusion: The results of this study show the high prevalence of venous leakage in patients referring for erectile dysfunction. Moreover, CT cavernosography was shown to be a useful method for evaluating penile venous system and its related leakage sites which are important for surgical planning.

Abstract

Background: Prostate cancer is the most common cancer and the second cause of cancer mortality in men. Although histopathological examination is the gold-standard for its diagnosis, tendency toward less invasive methods is growing. The purpose of this study was to evaluate the relationship between choline plus creatine- to-citrate ratio in magnetic resonance spectroscopy (MRS) with the invasion of prostate cancer in a series of patients with prostate cancer.
Methods: Totally, 200 patients with pathologically proven prostate cancer were enrolled in this cross-sectional study by a non-probability sampling method in Hazrat Rasul Akram Hospital in Tehran, Iran during 2009-2010. Pathological staging was the gold standard for the diagnosis of prostate cancer while the patients underwent MRS for choline plus creatine- to-citrate ratio determination. MRS and pathological results were compared and analyzed.
Results: The mean (±SD) values of choline plus creatine- to-citrate ratio in patients with Gleason scores less than 3, 3 to 4 and greater than 4 were 245.8±146.8, 427.1±173.6 and 427.1±173.6, respectively (P<0.001). The mean (±SD) values of choline plus creatine- to-citrate ratio in patients with PSA levels less than 4, 4 to 10 and greater than 10 were 180.7±58.3, 247±93.5 and 385.1±106.6, respectively (P<0.001).
Conclusion: Choline plus creatine- to-citrate ratio determined by magnetic resonance spectroscopy has a significant relationship with the degree of invasion of prostate cancer and can be used for the staging of the disease.

Abstract

Background: Prostate cancer is the third leading cause of death and is the most common cause of cancer in elderly men. Regarding to the low accuracy of screening methods such as prostate-specific antigen (PSA), Digital Rectal Examination (DRE) and trans rectal ultrasound (TRUS) in detection and localization of tumor, Magnetic Resonance Imaging (MRI) and Diffusion Weighted Imaging (DWI) attracted many attentions in the past years. DWI reveals micro-molecular diffusion, which is the Brownian motion of the spins in biologic tissues. This technique can delineate pathologic lesions with high tissue contrast against generally suppressed background signal. In this paper, the value of DWI in detection of prostate cancer is studied.
Methods: In this cross-sectional study, the studied population are suspicious patients to prostate cancer based on high Prostatic Specific Antigen level or abnormal Digital Rectal Examination who refered for prostate biopsy to radiology department of Hazrat-e- Rasoul Hospital during the year 2011. The results of DWI are compared to biopsy results for all patients.
Results: Eighty five patients are selected. The DWI sensitivity in detecting of prostate cancer is 100%, specificity 97.1% and positive and negative predictive values are 89.5% and 100%, respectively. The results showed that if DWI reports the prostate cancer as negative, the result was highly reliable and if it reports as positive, although the report was not 100% reliable, but it still had high reliability, more than 90%.
Conclusion: DWI had high accuracy in detecting prostate cancer for patients with cancer. Also the accuracy of this method for patients without prostate cancer was acceptable compared to the other common methods.

Abstract

Background: Head lice (Pediculus humanus capitis) are obligate ectoparasites of mankind, and are mainly transmitted head to head directly from one person to another. Human head lice treatment is faced with some challenges such as lack of complete treatment and the need for treatment repeatedly. The aim of this study was to evaluate the efficacy of two pediculicide products (substances used to treat human head lice infestation); 1% permethrin shampoo and 4% dimethicone lotion.
Methods: In this clinical trial, 140 cases of head lice infested people that were referred to the urban comprehensive health centers of Qom provincial health center related to Qom University of Medical Sciences and Health Services, Iran, from April to March 2017. The cases randomly were treated with two pediculicide products; 1% permethrin shampoo and 4% dimethicone lotion. The outcome of the treatment included removal of adult human head lice, nymphs, and nits in confirmed human cases at 14 and 21 days after starting treatments were considered.
Results: The success rate of human head lice infestation treatment in case of double use (at one-week intervals) with 1% permethrin shampoo and 4% dimethicone lotion was 65.7% and 62.9%, respectively. There was no statistical significance between the therapeutic effects of the two above-mentioned methods (odds ratio=1.22, P=0.59, CI=0.6-2.5). While the recovery rate of men compared to women was 3.8 (P=0.036), it was 3.1 (P=0.05) for housewives compared to students, and in families with one case compared to ones with more than one patient, this rate was found to be 3 (P=0.034). Family size was one of the most important variables that had a significant effect on the therapeutic rate of 1% permethrin shampoo and 4% dimethicone lotion.
Conclusion: The findings of this study do not support the reduction in efficacy of 1% permethrin shampoo and 4% dimethicone lotion as pediculicide products.

Abstract

Background: The pandemic of Covid-19 is spreading around the world. Extensive research is needed to focus on identifying the underlying causes of the disease. This study aimed to investigate the clinical and etiological symptoms of the Covid-19.
Methods: This descriptive-analytical study, conducted on 510 infected patients in the infectious disease clinic of Imam Khomeini Hospital in Tehran from March 2019 to June 2020 for A period of Four months during the first wave of Covid-19 pandemic. The method of selecting patients was continuous and was divided into two groups of 179 inpatients and 331 outpatients based on lung scan and clinical symptoms. Demographic information, clinical signs, and risk factors were collected through a questionnaire and the data were statistically analyzed.
Results: Symptoms such as fever, chills and cough were reported in the majority of patients in both groups, to such an extent that they were present in 176 (52%) of outpatients and in 101 (59%) of inpatients. The mean hemoglobin measured in hospitalized patients was lower, P=0.001). Vitamin D3 supplementation was reported in 30% of outpatients and in 16.5% of hospitalized patients (P=0.001). This means that vitamin D3 consumption is higher in the outpatient group.
The results showed that Chronic diseases such as hypertension was 4.9 times more likely (OR=4.9, 95% CI2. 433-10.25, P=0.0001) and anemia with 22 times more likely (OR=22.905, 95% CI9. 355-56.083, P=0.000) to be effective in the severity of the disease. It seems Vitamin D3 intake has a supportive effect on reducing the severity of the disease and decreases the risk of the disease getting worse.
Conclusion: Fever, chills and cough were important symptoms in identifying infected patients with Covid-19. According to the results of the present study and the findings of other studies, the supportive effect of vitamin D3 in reducing the severity of infectious diseases should be considered. Clinical trials with appropriate sample size are recommended to investigate the functional role of this vitamin in Reducing the severity of viral diseases of the respiratory tract.

Abstract

Background: Prostate cancer (PCa) has been one of the most prevalent cancers in men in recent years. Multi-parametric magnetic resonance imaging (mp-MRI) has been increasingly applied in the diagnosis, localization and staging of prostate cancer. This approach uses a combination of morphology information obtained from T2-weighted image along with at least two functional imaging modalities, such as diffusion-weighted (DWI), dynamic-contrast-enhancement (DCE), and magnetic-resonance-spectroscopy (MRS). This review gives a comprehensive overview of the theories and methodologies of the mp-MRI for diagnosing prostate cancer. The search was fulfilled using a list of search engines.
Methods: In this study, with a systematic review of studies conducted during February 2015 to October 2021, the role and potential of integrating the results of morphological and functional imaging in a multi-parameter approach were evaluated and the optimal combination was introduced. This article collected studies that have employed mp-MRI in prostate cancer including: peer-reviews, research articles, academic reports and conferences. This review has been studied from September 2016 to January 2022.
Results: According to the reported results, the optimum combination of T2-w, DWI and DCE in the mp-MRI approach provides the highest sensitivity and specificity in the diagnosis, localization and staging of prostate cancer. Applying the field strength of 3T versus 1.5T improves detection accuracy including improving sensitivity and specificity as well, and also the application of endorectal coils does not provide much advantage compared to pelvic phased-array coil in term of prostate cancer detection accuracy. 
Conclusion: MP-MRI as a precision instrument plays a valuable role in the diagnosis of prostate cancer. The most suitable combination of the pulse sequences to achieve the goals of this approach is T2-w, DWI and DCE. This review is comprehensive overview covered previous articles of mp-MRI in prostate cancer for all the researchers in this field and expresses the positive and negative points of each modality. Moreover, this article reports the sensitivity and the Specificity of the recent researches.
