: The hippocampus is a small but complex anatomical structure that plays an important role in spatial and episodic memory. The hippocampus can be affected by a wide range of congenital variants and degenerative, inflammatory, vascular, tumoral and toxic-metabolic pathologies. Magnetic resonance imaging is the preferred imaging technique for evaluating the hippocampus. The main indications requiring tailored imaging sequences of the hippocampus are medically refractory epilepsy and dementia...

Chronic degenerative tendon injuries as well as injuries due to acute high-energy trauma and incisional injuries are a significant aspect in the emergency surgery department. As a result of anatomical characteristics and exposure certain tendons are particularly vulnerable to injury. These include the biceps brachialis, quadriceps femoris, patella, achilles and tibialis anterior tendons. Besides the broad spectrum of non-surgical treatment, surgeons should have knowledge of the various surgical techniques including suturing, anchor refixation and reconstruction techniques...

Brain trauma is often associated with severe morbidity and is a major public health concern. Even when injury is mild and no obvious anatomic disruption is seen, many individuals suffer disabling neuropsychological impairments such as memory loss, mood dysfunction, substance abuse, and adjustment disorder. These changes may be related to subtle disruption of neural circuits as well as functional changes at the neurotransmitter level. In particular, there is considerable evidence that dopamine physiology in the nigrostriatal and mesocorticolimbic pathways might be impaired after TBI...

Sonography is an ideal, effective, noninvasive tool for evaluation of the spinal cord in neonatal and early infantile age groups owing to lack of ossification of the posterior elements of spine. Understanding normal anatomical appearances is a prerequisite for the interpretation of various pathologies of the spinal canal and its contents. This review elucidates normal appearances of the spinal cord in this age group, in both axial and sagittal planes. Usefulness of Doppler sonography is briefly discussed, and special emphasis is placed on normal anatomical variants that may mimic spinal abnormalities...

INTRODUCTION AND HYPOTHESIS: We provide a review of the literature about the onset and development of hypertrophy of the labia minora, together with some expert opinions on the appropriateness of labiaplasty. METHODS: We searched PubMed and used popular search engines, with a greater emphasis on the physiology and hormone-mediated metabolism of these structures, and less emphasis on their surgical treatment. RESULTS: We describe major embryological, cytological, and biochemical features of this anatomical part and summarize the clinical aspects of its hypertrophy, evaluating types of discomfort reported by women and the medical treatments available...

: Injuries of the vocal folds frequently heal with scar formation, which can have lifelong detrimental impact on voice quality. Current treatments to prevent or resolve scars of the vocal fold mucosa are highly unsatisfactory. In contrast, the adjacent oral mucosa is mostly resistant to scarring. These differences in healing tendency might relate to distinct properties of the fibroblasts populating oral and vocal fold mucosae. We thus established the in vitro cultivation of paired, near-primary vocal fold fibroblasts (VFF) and oral mucosa fibroblasts (OMF) to perform a basic cellular characterization and comparative cellular proteomics...

For deep carious lesions, a more conservative treatment modality ("selective caries removal") has been proposed, where only the heavily contaminated dentine is removed. In this regard, effective adjuncts for cavity disinfection such as the antimicrobial photodynamic therapy (aPDT) can be valuable clinically prior to definitive restoration. Therefore, the aim of this study was to systematically assess clinical studies on the effectiveness of aPDT as a supplementary tool in the treatment of deep caries lesions...

BACKGROUND: Our goal was to analyze the movement of acute scaphoid waist fracture fragments and adjacent bones in a common coordinate system. Our hypothesis was that the distal scaphoid fragment flexes and pronates and the proximal fragment extends. METHODS: Computed tomography (CT) scans of patients diagnosed with an acute scaphoid waist fracture were evaluated using a 3-dimensional (3D) model. The scans of 57 nondisplaced and 23 displaced fractures were compared with a control group of 27 scans showing no pathological involvement of the wrist...

Recurrent median neuropathy is an uncommon injury that can be commonly mistaken for other pathological causes. It is important to be aware of the potential causes and symptoms of injury as delay in diagnosis can lead to permanent decrease in hand function and disability. This case is a description of a 33-year-old male patient who previously presented with radicular symptoms and had complete resolution of his pain after a C7 selective nerve root block. Several months after presentation, he developed significant thenar atrophy, localized pain, and weakness associated with weight lifting activities...

PURPOSE: We have discussed the diagnosis and treatment approaches in patients with discontinued (disconnected or fractured) ventriculoperitoneal (VP) shunts that caused mechanical dysfunction. METHODS: Between 2006 and 2016, VP shunt surgery was performed on 1357 pediatric patients in our clinic. In follow-up examinations, we retrospectively reviewed patients who underwent revision surgery. Except for diagnosis of discontinued VP shunt, by excluding revision-surgery patients, only those patients who underwent surgical treatment owing to discontinued (fracture or disconnection) catheter were included in the study...

The study aims to describe a three-dimensional printed (3DP) posterior fixation implant used for C1/C2 fusion in a 65-year-old female. Spinal fusion remains a common intervention for a range of spinal pathologies including degenerative disc and facet disease when conservative methods are unsuccessful. However, fusion devices are not always entirely efficacious in providing the desired fixation, and surgeons rely on 'off the shelf' implants which may not provide an anatomical fit to address the particular pathology...

Quantitative cephalometry plays an essential role in clinical diagnosis, treatment, and surgery. Development of fully automated techniques for these procedures is important to enable consistently accurate computerized analyses. We study the application of deep convolutional neural networks (CNNs) for fully automated quantitative cephalometry for the first time. The proposed framework utilizes CNNs for detection of landmarks that describe the anatomy of the depicted patient and yield quantitative estimation of pathologies in the jaws and skull base regions...

Ozgur Samancilar, Tevfik İlker Akçam, Seyda Ors Kaya, Serpil Sevinc, Onur Akcay, Kenan Can Ceylan
Although it is not a pathologically significant entity, cases of azygos lobe (AL) are interesting due to the difficulty of performing video-assisted thoracoscopic surgery (VATS) procedures in the affected patients and the presence of a congenital malformation. Currently, videothoracoscopic surgery has advanced to such a level that most thoracic procedures can be performed with video assistance. However, some technical difficulties may arise in cases with anatomical anomalies such as AL. This report presents the case of a patient with an azygos lobe who underwent videothoracoscopic lung resection due to the presence of non-small-cell lung carcinoma in the upper lobe of the right lung...

REVIEW
Hyun Woo Goo, Young-Shin Ra
Conventional anatomic brain MRI is often limited in evaluating pediatric brain tumors, the most common solid tumors and a leading cause of death in children. Advanced brain MRI techniques have great potential to improve diagnostic performance in children with brain tumors and overcome diagnostic pitfalls resulting from diverse tumor pathologies as well as nonspecific or overlapped imaging findings. Advanced MRI techniques used for evaluating pediatric brain tumors include diffusion-weighted imaging, diffusion tensor imaging, functional MRI, perfusion imaging, spectroscopy, susceptibility-weighted imaging, and chemical exchange saturation transfer imaging...

The cerebral vasculature is a complex tridimensional network of arterial and venous vessels which are anatomically in proximity of and functionally coupled to neurons. Depending on the cellular composition of the vascular wall and its anatomical arrangement, cerebral vessels control regional blood flow, define interstitial homeostasis or cerebrospinal fluid circulation and influence immune cell patrolling. Pathological deviations from these functions promote or are a consequence of brain diseases, directly impacting neuronal firing...
