Article Type: Original Article | First Published: June 22, 2019
Computed Tomography (CT) has become an important tool for diagnosing cancer and to obtain additional information on different clinical issues. The radiation dose values in computed tomography depend on the scan acquisition protocol. Today, it is a very fast, painless and noninvasive test that can be performed high quality images. Therefore, it is indispensable to improve protocols, seeking smaller doses, without impairing the diagnostic quality of the image. The doses received are related with risks of stochastic effects. Based on this information, in this study, a cylindrical phantom and an o...

Computed Tomography (CT) has become an important tool for diagnosing cancer and to obtain additional information on different clinical issues. Today, it is a very fast, painless and noninvasive test that can be performed high quality images. However, CT scans usually require a higher radiation exposure than a conventional radiography examination. Head CT scans are used for diagnosis of traumatic head injuries, infections and other diseases with instability. Based on this information, three head scans were performed using the routine protocol used in the radiodiagnosis service, programming the ...

Nephroenteric fistulas are rare and generally occur as a result of chronic inflammation, ischemia or necrosis. Nephrectomy and primary closure of the fistulous tract currently represent the mainstay of treatment for non-functioning kidneys but kidney preservation should be attempted in cases of traumatic fistulae. The authors report a case of a 69-year-old female with an infected subcapsular renal haematoma and a fistulous tract to the duodenum following ureteroscopic laser lithotripsy of a right proximal ureteral calculus....

Article Type: Case Report | First Published: June 12, 2019
Intracranial meningeal hemangiopericytomas (HPCs) represent a rare and aggressive intracranial neoplasm located along the dural sinuses, tend to recur and metastasize, and account for less than 1% of intracranial tumours and approximately 2~4% of all meningeal tumors. We discuss herein the dynamic of HPCs and review the literatures from its clinical symptoms, imaging features, histopathological features, differential diagnosis and treatment and prognosis, and present a case of a 35-year-old male with metastatic recurrence of an intracranial hemangiopericytoma, who underwent resection of primar...
Personalized Medicine and Psychoanalysis: How Pharmacogenomic Testing Facilitates Depression Treatment
Article Type: Review Article | First Published: June 14, 2019
Pharmacogenomic testing offers enormous potential to manage mental disorders like depression. But many psychoanalysts aren't aware of its value and biotechnical power. This article explains how this form of personalized medicine can be used to aid in the treatment of patients with depression. With over 20 medications approved by the FDA to treat depression, and many others recommended for off-label use, treatment failure with antidepressants commonly occurs in clinical practice. Inviting genetic testing into the treatment plan when working with depressed patients can reduce the rate of medicat...

The aim of our study was to evaluate the efficacy of n-Heptane (C7H16) as a xylene substitute for clearing, deparaffinizing and staining procedures in routine histopathology. 30 biopsied oral tissues were divided in two halves, each half was processed by xylene and n-Heptane respectively. Kappa statistical analysis established agreement between observers in all criteria's with significant p value < 0.05. The p value (> 0.05) was not statistically significant with Mann-Whitney U Test, for all criteria's indicating comparable results between n-Heptane and xylene. The clarity, uniformity, crispne...
