BACKGROUND: To verify the usefulness of a new algorithm for preoperative differential diagnostics of parotid tumors on the basis of their dynamic and diffusion-weighted MR images. METHODS: The retrospective analysis included 158 consecutive surgical patients with parotid tumors. Aside from ultrasound-guided fine needle biopsy, the protocol of preoperative evaluation included dynamic and diffusion-weighted MRI. According to the new diagnostic algorithm, the result of fine needle biopsy was considered only in the case of lesions with time to peak enhancement (Tpeak) > 60 s and washout rate (WR) ≤ 30% on dynamic MRI and apparent diffusion coefficient (ADC) ≤ 1...

Multislice/multidetector-row computed tomography (MDCT) is now widely used for noninvasive assessment of coronary arteries, and it may sometimes reveal coronary anomalies. Detection of such anomalies may be relevant both during follow-up and for planning cardiac or coronary surgical/interventional procedures. These anomalies may be missed unless carefully sought. In this paper, we present the MDCT images of a first septal perforator branch originating from the left main coronary artery, which represents an extremely rare coronary anomaly...

Primary heart tumors in the pediatric population are very rare and they range from 0.01% to 0.04%. Most are benign lesions of which about half are rhabdomyomas. Rhabdomyoma tumor diagnosis is associated with a 75-80% risk of TSC. TSC are characterised with numerous changes of hamartoma type located in the brain, kidneys, skin and other organs including in the heart. More than two thirds of newborns with TSC present rhabdomyomas in the heart. These changes may be asymptomatic, but in some cases they may cause heart failure, arrhythmias and death...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is marked by destruction of alveolar architecture. Preclinical modeling for COPD is challenging. Chronic cigarette smoke exposure, the reference animal model of COPD, is time-inefficient, while exposure to waterpipe smoke (WPS), a surging smoking modality, was not fully tested for its histopathological pulmonary consequences. Since alveolar damage and pulmonary vascular endothelial dysfunction are integral to COPD pathology, lung histopathological effects of WPS were temporally evaluated, alone or in combination with vascular endothelial growth factor receptor (VEGFR) inhibition in mice...

An upward displacement of the odontoid process into the foramen magnum was observed in the skeletal remains of a young male unearthed from a 14th-17th century cemetery in the north-eastern Italy. Examination of skull bone vestiges and CT-SCAN analysis of the axis exhibited a clear-cut contact zone between the odontoid process and the anterior border of the foramen magnum. In addition, the odontoid process appeared backward deviated. Findings suggest a possible diagnosis of basilar impression/invagination. This anomalous contact may cause compression of neural and vascular structures with a multifaceted series of clinical symptoms...

BACKGROUND: Early life adversity (ELA) is not uncommon in Major Depressive Disorder (MDD) patients. Childhood trauma has been reported more frequently in adult MDD patients relative to healthy control. Recent researches have demonstrated that ELA could result in changes in brain morphology which might be an etiological factor of MDD development. MATERIALS AND METHODS: We recruited 40 young adult patients suffered from MDD and made CT scan. Subjects were divided in two groups: MDD patients with ELA experience (E+D) vs MDD patients without ELA experience (E-D) according to Chinese version-Childhood Trauma Questionnaire (CTQ)...

BACKGROUND: Anatomical variations of the middle cerebral artery (MCA) are an important clinical issue, due to high prevalence of intracranial aneurysms. Anatomical variations of vessels can lead to higher shear stress, which is thought to be the main factor leading to aneurysm formation and consequently to higher prevalence of aneurysms. The aim of this study was to evaluate anatomy of the MCA; to classify MCA aneurysms using CT angiography and to correlate anatomical variations of MCA and circle of Willis with prevalence of MCA aneurysms...

Periodontal tissue remnants of odontogenesis constitute the dental follicle (DF) which is actually considered a stem niche in adults. However, potentialities of local endothelia within this niche seem overlooked. We thus aimed at testing the endothelial cells expression of c-kit, the progenitor cells marker, and CD68, commonly regarded as a monocyte/macrophage marker, in human DFs. We performed an immunohistochemical study using these two markers which were applied on samples collected from ten adult patients...

Common presentation of atretic parietal cephalocele (APC) is mostly seen in infants and young children. And, it is a palpable midline parietal soft tissue mass which is thought to represent involuted true cephalocele (meningocele or encephalocele)connected to dura mater via a fibrous stalk. The incidence of intracranial anomalies have increased with APC. Parietal cephaloceles comprise about 1% of all cerebrospinal congenital malformations and 10% of cephaloceles. We report here the case of an atretic parietal cephalocele with no associated brain malformations in adult...

The aim of this study was to investigate the immunohistochemical characteristics of the haemal nodes located in the abdominal and the thoracal cavity in roe deer (Capreolus capreolus). In this study, two adult male and two adult female roe deers in addition to two roe deer foetuses at the late fetal stages were used. The avidin-biotin-peroxidase technique was applied to anti-CD3, anti-CD79αcy, anti-macrophage, anti-S100 primary antibodies. Positive results were gained for all the antibodies used. Many CD3 positive T lymphocytes were seen in the lymphoid tissue areas of the fetal haemal nodes, in the germinal center of the lymph follicles of the adult haemal nodes and in their lymphatic cords...

BACKGROUND: Epistaxis is a frequent problem otorhinolaryngologists faces of in their practice. The variations of the sphenopalatine foramen and consequently the artery may be one of the major sources of such bleeding. AIM OF THE WORK: The present work aimed at to localize the site of sphenopalatine foramen and also to illustrate its different shapes, number and any other variation. MATERIALS AND METHODS: In the current study, twenty adult skulls of both sexes with total 40 half skulls were used in addition to 20 heads of adult living subjects of both sexes aged between 30-60 years examined with multislice helical CT with 3-D reconstruction of SPF...

BACKGROUND: The ultrastructural alterations related to tendinopathy have not been well described. Most studies on this subject have been conducted many years ago and focused on material from the Achilles tendon. It was demonstrated that various comorbidities can affect ultrastructural alterations in the advanced tendinopathy, however there is very little data on ultrastructural morphology in tendinopathies related to mechanical overload as in case of the long head of the biceps brachii tendon (LHBT)...

The effect of insulin on the endocrine pancreas has been the subject of extensive study, but quantitative morphometric investigations of the exocrine pancreas are scarce. This study was therefore undertaken to investigate the effect of acute and chronic insulin administration (two doses, 0.4 IU and 4 IU) on the morphology of rat pancreas acini. Semi-fine sections stained with methylene blue and basic fuchsine or hematoxylin- and eosin-stained 5-micrometer thick paraffin sections were used for fractal and stereological analysis of exocrine acini...

BACKGROUND: Communications between the median, ulnar and musculocutaneous nerves in the arm, forearm and hand were reported in adult cadaveric and electrophysiological studies. These communicant branches may lead conflicting clinical and electrodiagnostic outcomes. While there are many studies on adult patients or cadavers, there is poor regarding fetuses. The present study was conducted to examine the frequencies of these communications and their coexistences in human fetuses. MATERIALS AND METHODS: Anterior aspect of the forearms of 50 fetuses (29 females, 20 males, and 1 unknown) were dissected bilaterally (totally 100 sides) for this purpose...
