Diagnosis and management of a rare case of encysted hydrocele of spermatic cord: Case report and literature review.

INTRODUCTION AND IMPORTANCE: A hydrocele is typically a non-cancerous condition that arises from the accumulation of fluid between the layers of the vaginal process. Diagnosis primarily involves a physical examination. In instances where the condition is mistaken for other pathological conditions, additional investigations may be undertaken. Surgical intervention is typically deferred until after the age of one year, unless the hydrocele is significantly large. CASE PRESENTATION: A case was presented of a 4-year-old boy who was referred to the hospital with a suspected deep inguinal hernia. Upon examination, it was determined that the mass was actually an encysted hydrocele of spermatic cord. The patient underwent a minimally invasive surgery to remove the spermatocele, and the procedure was successful. CLINICAL DISCUSSION: This emphasizes the importance of obtaining a detailed patient history and conducting a comprehensive physical examination, which often provide sufficient information to make a diagnosis. In many instances, these initial steps can spare patients from undergoing additional tests that may be invasive or pose unnecessary risks. CONCLUSION: It is important to note that in cases of hydroceles, conservative treatment, such as observation, is the primary approach before the age of one year. Surgery is typically reserved for older children or those with large hydroceles.

Diagnostic Efficacy of PSMA and PSCA mRNAs Combined to PSA in Prostate Cancer Patients.

BACKGROUND: Serum Prostate-specific antigen (PSA) has been used for screening and diagnosis of prostate cancer (PCa) but it is burdened by its low accuracy, creating a need for reliable diagnostic markers. Despite prostate-specific membrane antigen (PSMA) and prostate stem cell antigen (PSCA) being widely expressed in the tissue of PCa, no definite conclusion regarding their use as clinical biomarkers due to their lacking organ specificity. Therefore, this study aimed to evaluate the peripheral blood levels of PSMA and PSCA mRNAs and examine their diagnostic significance as non-invasive integrated markers.

Materials and Methods: 125 subjects were enrolled in this study. They were divided into 25 healthy controls, 25 BPH patients, and 75 PCa patients. The expression levels of PSMA and PSCA were determined using quantitative RT- PCR, in addition to measuring serum PSA.

Results: Levels of PSMA and PSCA were over-expressed in PCa patients compared to controls and BPH patients and were found to be associated with increased susceptibility to PCa. Moreover, the diagnostic values of PSMA and PSCA to distinguish PCa patients from BPH patients and controls were inferior to that of PSA. However, the combination of PSMA and PSCA with PSA enhanced the efficacy of the latter.

Conclusion: This study suggests that these genes were associated with malignant susceptibility. Concerning the duality of PSMA-PSA or PSCA-PSA, this implies the significance of their investigation together in peripheral blood of prostate patients.

Radioprotective effects of N-acetylcysteine on rats' brainstem following megavoltage X-irradiations.

PURPOSE: This study aimed to determine the radioprotective effect of N-acetylcysteine (NAC) on the radiation-induced oxidative stress (OS) in the rats' brainstem. MATERIALS AND METHODS: Eighty rats in four identical groups, including vehicle control (VC), irradiation alone (RAD), irradiation with 1 g/kg of NAC treatment (RAN), and NAC treatment without radiation (NAC) were used. Whole-brain irradiation was performed with a single dose of 25 Gy. The rats received the treatments via intraperitoneal (IP) injection 1 h before the irradiation process. Nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), total antioxidant capacity (TAC), and glutathione peroxidase (GPx) were measured in the rats' brainstem and compared between the groups. Furthermore, the pathological study was performed to assess tissue damage after 24 h, 72 h, and 5 days of irradiation. RESULTS: The levels of NO and MDA in the brainstem tissue for the RAD group were 60.37 ± 3.35 µmol/L and 45.10 ± 2.48 µM, respectively, which were higher than those of VC group (NO: 30.41 ± 1.83 µmol/L; MDA: 31.02 ± 1.71 µM). The level of SOD, CAT, TAC, and GPx declined in the RAD compared to the VC group. Pre-treatment with NAC decreased the level of NO and MDA and also enhanced the antioxidant activities. The greatest pathological changes in the rats' brainstems were seen in RAD animals compared to the VC group at 24 h, 72 h, and 5 days. Furthermore, the pathological changes were not observed in the NAC group in all the assessed times. CONCLUSION: Based on the results, NAC can decrease the irradiation-induced oxidative stress and pathology damages in the rats' brainstem. It can be concluded that NAC can be an appropriate radioprotection candidate for the human brainstem.

Recent advances in biosensor devices for HER-2 cancer biomarker detection.

The human epidermal growth factor receptor 2 (HER-2) protein is a member of the epidermal growth factor receptor (EGFR or ErbB) family and is a transmembrane tyrosine kinase receptor. HER-2 is highly regulated in ovarian, lung, gastric, oral, and breast cancers. The low specificity, complexity, expensiveness and the lack of sensitivity are essential restrictions in traditional diagnosis methods such as FISH, immunohistochemistry and PCR and these disadvantages led to the need for more studies on alternative methods. Biosensor technology has greatly affected the quality of human life owing to its features including, sensitivity, specificity, and rapid diagnosis and monitoring of different patient diseases. In this review article, we examine various biosensors, considering that they have been categorized based on the transducers used including piezoelectric biosensors, optical sensors such as fluorescence and surface plasmon resonance, and electrochemical types for the diagnosis of HER-2 and the effectiveness of some drugs against that. Attention to developing some types of biosensor devices such as colorimetric biosensors for HER-2 detection can be an important point in future studies.

Preference of and factors that influence future specialty among medical students in Jordan: A cross-sectional study.

BACKGROUND: Choosing future specialty is an important issue that face undergraduate medical students during their university years. Several factors may assist to formulate students' final decision. We aimed to explore the future specialty preferences and the factors that influence the choice of undergraduate students in medical schools in Jordan. METHODS: A cross sectional study conducted among the sixth year students of two medical schools in Jordan. A questionnaire was used to collect data from the students. It consisted of demographic data in form of gender, GPA, family income, and parents' level of education. In addition to data about preferred specialties, and factors that influence medical students' choice of future specialty. RESULTS: A total of 223 medical students from two medical schools were recruited to participate. Males were 49.3% while females were 50.7%, and around 22% scored an excellent GPA. Most parents of the students were bachelor degree holders (63.6% for fathers and 62.3% for mothers). Medicine (19.4%), dermatology (12.6%), and obstetrics and gynecology (11.7%) were the most chosen future specialties. Specialty appeal and thoughts of future creativity was the most chosen factor that influenced future specialty (55.2%) choice, followed by family time and less on-call duties (14.8%). Students who selected chances of fellowships as an influencing factor were more likely to prefer medicine as future specialties (p < 0.001). CONCLUSION: Medicine, dermatology, and obstetrics and gynecology were the most popular future specialty choices among undergraduate medical students. Most of our medical students claimed that selection of their specialty is based on the interest and potential creativity, family time and less on call duties. Further studies are required in a wide range to accommodate more students from the other academic years.

The recent advances, drawbacks, and the future directions of CMRI in the diagnosis of IHD.

Ischemic heart disease (IHD), also known as coronary artery disease (CAD), is a leading cause of morbidity and mortality in adults. The aims of this research were to study the recent advances on the prognostic and diagnostic value, drawbacks, and the future directions of cardiac magnetic resonance imaging (CMRI) in the diagnosis of IHD. One hundred patients with IHD who had been clinically diagnosed were enrolled in this study prospectively. CMRI; Siemens Magnetom Sola 1.5 T MRI scanner was used to examine the patients. To confirm the diagnosis, conventional coronary angiography was used. CMRI revealed that the left ventricular (LV) volumes and systolic function of male and female patients differed by age decile were 28.9 ± 3.5%; 32 ± 1.7%, 53.3 ± 11.2; 58 ± 6.6 ml, 100.6 ± 7.1; 98.3 ± 14.7 bpm, 5.4 ± 1.4; 5.8 ± 1.5 L/min, 189 ± 14.3; 180 ± 10.9 ml, and 136 ± 3.1; 123 ± 4.4 ml for the left ventricle ejection fraction (LVEF), stroke volume (SV), heart rate, cardiac output, end diastolic volume (EDV), and end systolic volume (ESV), respectively. CMRI has sensitivity, specificity, and accuracy of 97%, 33.33%, and 95.15%, respectively. Finally, CMRI provides a comprehensive assessment of LV function, myocardial perfusion, and viability, as well as coronary anatomy.

Achilles Tendon Measurements in Asymptomatic Saudi Adults Using High-frequency Ultrasound

ABSTRACT Objective: To measure the Achilles tendon length, thickness and cross-sectional area in asymptomatic adult Saudi participants and to investigate the possible changes in these measurements based on their different ages and body height. Methods: The prospective cohort study was done between January 2014 and March 2015. A total of 200 asymptomatic participants with 175 males (87.5%) and 25 females (12.5%) between the ages of 14 and 65 years, with the mean age of 25 ± 1.5 years, were scanned at two radiology departments. Ultrasound (US) scans for the Achilles tendons were performed using a Hitachi (EZU-MT30-S1 HI Vision Avius, Hitachi, Japan) US machine. Statistical Package for the Social Sciences (SPSS Inc., Chicago, IL, USA) was used to analyse the results. Results: There was no significant difference in the length, cross-sectional area and thickness of the Achilles tendons among the participants of different ages; however, the cross-sectional area of Achilles tendons of the older participants (≥ 47 years) was higher than that of the participants of the younger age groups. Moreover, there was no correlation between the length, cross-sectional area, and thickness of the Achilles tendons and their body heights; however, the participants of ≥ 153 cm in height showed an increase in their Achilles tendon cross-sectional areas. Conclusion: Ultrasound is a useful imaging tool in the assessment of the Achilles tendons. The normal variations of the tendon morphological characteristics should be considered in the clinical diagnosis. Additional studies on the correlations among the Achilles tendon length, thickness and cross-sectional areas of ethnicity of the participants in Saudi Arabia are suggested.

The Spectrum of Renal Pathologies in Saudi Pediatrics Patients Using Ultrasound.

BACKGROUND AND OBJECTIVE: The Kingdom of Saudi Arabia (KSA) has a high population of children with hereditary renal infections whose factors are linked to the X chromosomes. This study aims to determine the spectrum of renal pathologies in Saudi pediatrics patients as well as to link the genetic aspect to the development of renal diseases in Saudi children by using ultrasound. MATERIALS AND METHODS: The study, hence sought to analyze the outcomes of a cross-sectional retrospective study report at the Radiology department of King Fahad Medical City (KFMC) within 12 months retrogressively. Data was collected using ultrasound machines with B-mode and Doppler modes used to generate results that were later filled in forms. RESULTS: Demographic characteristics showed that even though the study incorporated the children between the ages of 1-14 years, renal infection was most prevalent in children between the ages 4-7 years. The study revealed that male children were at a higher risk of getting a hereditary renal infection compared to their female counterparts. Indications for renal ultrasound examination of the study samples indicated that the ectopic renal disease affected 2% of the 50 sample size, while hydronephrosis affected 26% of the sample. CONCLUSION: The current study was able to successfully highlight the role of ultrasound in the detection of a wide range of renal diseases among Saudi children. Additionally, this study attempted to link the genetic aspect to the development of renal diseases in Saudi children, but the use of ultrasound alone was not very helpful in this.

Brightness Mode and Color Doppler Ultrasound in Differential Diagnosis of Breast Lesions in Saudi Females.

OBJECTIVE: The aim of the study was to identify the pathological characteristics of benign and malignant breast lesions among Saudi females using brightness mode (B-mode) and color Doppler ultrasound (US). MATERIALS AND METHODS: This study was retrospectively carried out in a single center in the Radiology and Medical Imaging Department, King Fahad Medical City, Riyadh, Saudi Arabia. A convenient method of sampling was used to include all patients referred for different diagnosis during the period of January 2016 and December 2018. A sample size of 100 cases was selected with 50% of the cases being benign breast lesions, while the rest were malignant. The data collection instruments comprised data collection sheets, while a Philips US system with a 9 MHz linear probe was used to give the differential results. The results were considered significant when P < 0.05. The statistical diagnostic test was used to detect sensitivity, specificity, and accuracy of US in the differential diagnosis of breast lesions in Saudi females. RESULTS: B-mode and color Doppler US findings of breast mass measurements, shape, echotexture, and the presence and absence of vascularity present a sensitivity, specificity, and accuracy of 97.09%, 80.65%, and 93.28% in the diagnosis of benign and malignant breast masses. CONCLUSION: In Saudi females with dense breasts, the risk of breast cancer development is increased. Moreover, B-mode in combination with color Doppler US was highly determined the results of differential diagnosis for any breast lesions.

Incidental Extraspinal Findings in the Thoracic Spine during Magnetic Resonance Imaging of Intervertebral Discs.

OBJECTIVE: The purpose of this research was to determine the frequency of incidental extraspinal findings in the thoracic spine on magnetic resonance imaging (MRI). MATERIALS AND METHODS: A total of 120 thoracic spine MRI patients were prospectively examined in the period extending from August 2018 to April 2019. Both 1.5 and 0.35 Tesla MRI systems (Toshiba and Siemens Medical system) were applied to investigate patients with suspected intervertebral disc abnormalities at three MRI diagnostic centers in Khartoum, Sudan. RESULTS: Out of the 120 patients, incidental extraspinal findings were found in 16 patients (13.3%). Various incidental findings (IFs) were seen, including renal cysts, liver mass, thyroid goiter, and pleural effusion. Out of these IFs, 37.5% were considered clinically significant. CONCLUSIONS: Various IFs were identified during a routine thoracic spine MRI, and approximately one-third of them were clinically significant. Therefore, it is essential for the reporting radiologists to pay attention to extraspinal findings while reporting thoracic spine MRI to avoid missing clinically significant findings.

Impact of Khat (Catha edulis) Chewing on Carotid Intima-media Thickness.

BACKGROUND AND OBJECTIVE: Khat has severe adverse socio-economic consequences. It causes serious cardiovascular, neurological and psychiatric problems. The study aimed to evaluate the effect of chewing khat on intima-media thickness (IMT) of the common carotid arteries. MATERIALS AND METHODS: This was a descriptive case-control cross-sectional study. A total of 50 participants of chronic regular khat chewers were investigated. B-mode ultrasound 7-10 MHz linear transducers used for assessment of common carotid arteries according to the standard carotid sonography protocol. The IMT was measured and the presence of plaques was assessed. RESULTS: The carotid IMT was significantly increased in regular khat chewers more than the controls (p-value = 0.016). The common carotid IMT increased in smokers more than non-smokers among khat chewers (0.6710±0.20687 vs. 0.5789±0.16859 mm). Significant correlations existed between the duration of chewing khat and age with the presence of plaque (p-values = 0.013 and 0.002, respectively). CONCLUSION: There is a significant correlation between carotid plaque and longtime khat chewing. Khat is a contributory factor for increasing carotid intima-media thickness and formation of carotid plaques. A combination of khat and smoking produce more thickening of carotid intima-media.

Incidental extraspinal findings in the lumbar spine during magnetic resonance imaging of intervertebral discs.

PURPOSE: To calculate the frequencies of incidental extraspinal findings and incidentally detected congenital anomalies or anatomical differences in the lumbar spine on magnetic resonance imaging (MRI) scans of intervertebral discs. MATERIALS AND METHODS: A total of 379 lumbar spine MRI cases were prospectively investigated in the period spanning from August 2016 to January 2018. Both 1.5 and 0.35 Tesla MRI units (Toshiba and Siemens Medical Systems) were used to examine patients with clinically suspected intervertebral disc abnormalities at three MRI diagnostic centers in Khartoum State, Sudan. RESULTS: Of the 379(100%) patients, 90(23.7%) patients were presented with incidental findings. Among the incidental findings, 39(10.3%) were renal cysts, 10(2.6%) were retroverted uteri, 5(1.3%) were Nabothian cysts, 4(1.1%) were ovarian cysts, 10(2.6%) were uterine fibroids, 3(0.8%) were endometrial thickening, 11(2.9%) were indicative of hydronephrosis, 4(1.1%) were uncovered prostatic enlargement, 2(0.5%) were atrophic kidney, and 1(0.3%) each was of an ectopic kidney and bladder wall thickening, respectively. CONCLUSIONS: A high percentage of extraspinal pathological findings were detected during MRI lumbar spine scans of intervertebral discs. Thus, it is important to be aware of the high percentage of patients who undergo further evaluation given the presence of unexpected findings, but for whom clinical confirmation of these abnormalities is not obtained.

Duplex ultrasound for evaluation of deep venous blood flow in fractured lower extremities.

PURPOSE: Early identification of deep venous thrombosis (DVT) in trauma patients would result in an early initiation of treatment, thereby decreasing the frequency of complications. The aim of the current study was to evaluate the role of duplex ultrasound (DUS) in the evaluation of deep venous blood flow in fractured lower extremities to rule out DVT prior to orthopedic surgery. MATERIAL AND METHODS: In this prospective study a total of 58 patients (42 males and 16 females; mean age of 51.5 ± 19.5 years) with fractured lower extremities were thoroughly evaluated prior to surgery with respect to medical history, fracture pattern, associated injuries, comorbid conditions, and venous duplex ultrasound (VDUS) findings. Each affected limb was assessed for the presence of DVT using a Sonoline G 60S ultrasound unit. The analysis was performed with the Statistical Package for the Social Sciences (SPSS) version 20. RESULTS: DVT was found in 36 (62.1%) patients with single closed fractures, 9 (15.5%) patients with single opened fractures, 10 (17.2%) patients with multiple closed fractures, and in 3 (5.2%) patients with multiple opened fractures. Sensitivity and specificity of the findings of compressibility and phasicity for DVT detection in patients with fractured lower extremities were 81.25% and 87.50% and 100% and 100% respectively. In addition, the absence of compressibility and phasicity had positive predictive value of 100% and 100% and negative predictive value of 93.75% and 95.65% respectively. CONCLUSIONS: US of DVs in the brightness mode (B-mode) with compression maneuvers should be the first-line imaging modality for suspected DVT in patients with fractured lower extremities.

Evaluation of the antitumor activity of platinum nanoparticles in the treatment of hepatocellular carcinoma induced in rats.

This study aimed to evaluate the antitumor activity of platinum nanoparticles compared with cis-platin both in vitro and in vivo in the treatment of hepatocellular carcinoma induced in rats. The treatment efficacy of platinum nanoparticles was evaluated by measuring antioxidant activities against oxidative stress caused by diethylnitrosamine in liver tissue. The measurements included reduced glutathione content and superoxide dismutase activity, as well as malondialdehyde level. Liver function tests were also determined, in addition to the evaluation of serum alpha-fetoprotein, caspase-3, and cytochrome c in liver tissue. Total RNA extraction from liver tissue samples was also done for the relative quantification of B-cell lymphoma 2, matrix metallopeptidase 9, and tumor protein p53 genes. Histopathological examination was also performed for liver tissue. Results showed that platinum nanoparticles are more potent than cis-platin in treatment of hepatocellular carcinoma induced by diethylnitrosamine in rats as it ameliorated the investigated parameters toward normal control animals. These findings were well appreciated with histopathological studies of diethylnitrosamine group treated with platinum nanoparticles, suggesting that platinum nanoparticles can serve as a good therapeutic agent for the treatment of hepatocellular carcinoma which should attract further studies.

High-Intensity Focused Ultrasound (HIFU) in Localized Prostate Cancer Treatment.

BACKGROUND: High-intensity focused ultrasound (HIFU) applies high-intensity focused ultrasound energy to locally heat and destroy diseased or damaged tissue through ablation. This study intended to review HIFU to explain the fundamentals of HIFU, evaluate the evidence concerning the role of HIFU in the treatment of prostate cancer (PC), review the technologies used to perform HIFU and the published clinical literature regarding the procedure as a primary treatment for PC. MATERIAL/METHODS: Studies addressing HIFU in localized PC were identified in a search of internet scientific databases. The analysis of outcomes was limited to journal articles written in English and published between 2000 and 2013. RESULTS: HIFU is a non-invasive approach that uses a precisely delivered ultrasound energy to achieve tumor cell necrosis without radiation or surgical excision. In current urological oncology, HIFU is used clinically in the treatment of PC. Clinical research on HIFU therapy for localized PC began in the 1990s, and the majority of PC patients were treated with the Ablatherm device. CONCLUSIONS: HIFU treatment for localized PC can be considered as an alternative minimally invasive therapeutic modality for patients who are not candidates for radical prostatectomy. Patients with lower pre-HIFU PSA level and favourable pathologic Gleason score seem to present better oncologic outcomes. Future advances in technology and safety will undoubtedly expand the HIFU role in this indication as more of patient series are published, with a longer follow-up period.

High-Intensity Focused Ultrasound (HIFU) in Uterine Fibroid Treatment: Review Study.

BACKGROUND: High-intensity focused ultrasound (HIFU) is a highly precise medical procedure used locally to heat and destroy diseased tissue through ablation. This study intended to review HIFU in uterine fibroid therapy, to evaluate the role of HIFU in the therapy of leiomyomas as well as to review the actual clinical activities in this field including efficacy and safety measures beside the published clinical literature. MATERIAL/METHODS: An inclusive literature review was carried out in order to review the scientific foundation, and how it resulted in the development of extracorporeal distinct devices. Studies addressing HIFU in leiomyomas were identified from a search of the Internet scientific databases. The analysis of literature was limited to journal articles written in English and published between 2000 and 2013. RESULTS: In current gynecologic oncology, HIFU is used clinically in the treatment of leiomyomas. Clinical research on HIFU therapy for leiomyomas began in the 1990s, and the majority of patients with leiomyomas were treated predominantly with HIFUNIT 9000 and prototype single focus ultrasound devices. HIFU is a non-invasive and highly effective standard treatment with a large indication range for all sizes of leiomyomas, associated with high efficacy, low operative morbidity and no systemic side effects. CONCLUSIONS: Uterine fibroid treatment using HIFU was effective and safe in treating symptomatic uterine fibroids. Few studies are available in the literature regarding uterine artery embolization (UAE). HIFU provides an excellent option to treat uterine fibroids.

Evaluation of common carotid artery changes in Saudi current smokers using medical ultrasound (B-mode and Doppler).

PURPOSE: This study evaluates using ultrasound the changes that occur in wall thickness, blood flow velocity, and Doppler indices of the common carotid arteries (CCAs) in healthy Saudi adult males who are current smokers. METHODS: A prospective study was performed between May 2011 and May 2013 with a group consisting of nonsmokers (n = 180; 36 %) and current smokers (n = 320; 64 %) with a mean age of 25 ± 2.6 years. In all cases, the CCA ultrasound scanning protocol met the standards established by the American Institute of Ultrasound in Medicine (AIUM) to measure intima media thickness (IMT), peak systolic velocity (PSV), and end diastolic velocity (EDV). The Statistical Package for the Social Sciences (SPSS) was used to analyze the results. RESULTS: Significant linear and positive correlations were noted between the level of daily consumption of cigarettes smoked and carotid mean IMT, PSV, and Doppler indices, while a linear and negative correlation was present between cigarette smoking and mean EDV. These findings were significant when compared with the results for nonsmokers. CONCLUSIONS: Cigarette smoking is associated with CCA morphological changes caused by significant impairment of arterial endothelial function, and an increase in daily cigarette consumption significantly leads to a decrease in the blood flow velocity of CCAs.
