The incidence of segmental testicular infarction (STI) is very low. Such a disorder most often affects young men. The most common symptom is sudden testicular pain. We report 6 cases of men diagnosed with STI. Clinical examination, blood test, urine analysis, and ultrasound examination with colour Doppler were performed. Furthermore, tissue sonoelastography or MRI was performed in selected patients. All men underwent surgical exploration. In all but one man, the affected testis was preserved. Although STI is a rare condition, it should be taken into account if testicular pain prior to suspicious ultrasound imaging occurs...

REVIEW
Christoph Kraus, Eero Castrén, Siegfried Kasper, Rupert Lanzenberger
Serotonin modulates neuroplasticity, especially during early life, and dysfunctions in both systems likewise contribute to pathophysiology of depression. Recent findings demonstrate that serotonin reuptake inhibitors trigger reactivation of juvenile-like neuroplasticity. How these findings translate to clinical antidepressant treatment in major depressive disorder remains unclear. With this review, we link preclinical with clinical work on serotonin and neuroplasticity to bring two pathophysiologic models in clinical depression closer together...

Background: Patients on the selective serotonergic re-uptake inhibitors (SSRI) like citalopram report emotional blunting. We have shown previously that citalopram reduces resting-state functional connectivity (RSFC) in healthy volunteers in a number of brain regions including the dorso-medial prefrontal cortex, which may be related to its clinical effects. Bupropion is a dopaminergic and noradrenergic re-uptake inhibitor (DNRI) and is not reported to cause emotional blunting. However how bupropion affects RSFC in healthy controls remains unknown...

Background: Orthodontic diagnostic standards generally use the cranial base as a reference and rely on samples selected by orthodontists. Objective: The purpose of this study was to provide male and female standards for a novel non-radiographic approach for orthodontic diagnosis that utilizes 3D dentofacial photogrammetry using the eyes and natural head orientation as references instead of the cranial base. Methods: One hundred and eighty females and 200 males between the ages of 18 and 35 years from 2 modeling agencies were orthodontically screened for near ideal occlusion...

Wenjian Meng, Ziqiang Wang
Lateral pelvic lymph node metastasis is an important metastatic mode and a major cause of locoregional recurrence of mid-low rectal cancer. Recently, there is an East-West discrepancy in regard to the diagnosis, clinical significance, treatment and prognosis of lateral pelvic lymph node metastasis. In the West, lateral nodal involvement may represent systemic disease and preoperative chemoradiotherapy can sterilize clinically suspected lateral nodes. Thus, in many Western countries, the standard therapy for lower rectal cancer is total mesorectal excision with chemoradiotherapy, and pelvic sidewall dissection is rarely performed...

OBJECTIVE: As most orthognathic surgeries focus on the lower face, the aim of this study was to transfer previously developed two-dimensional cephalometry-which is useful for surgeons in the orthognathic surgery of the lower face-to three-dimensional (3D) cephalometry by using cone-beam computed tomography (CBCT). We selected the quadrilateral lower face analysis developed by the surgeon Di Paolo, who focused only for the lower face and mentioned that data in millimeters are more easy to use than angles for surgeons...

Background and purpose - The accuracy of using clinical measurement from the anterior superior iliac spine (ASIS) to the center of the knee to determine an anatomic axis of the femur has rarely been studied. A radiographic technique with a full-length standing scanogram (FLSS) was used to assess the adequacy of the clinical measurement. Patients and methods - 100 consecutive young adult patients (mean age 34 (20-40) years) with chronic unilateral lower extremity injuries were studied. The pelvis and intact contralateral lower extremity images in the FLSS were selected for study...

Tricuspid regurgitation (TR) is a highly prevalent valvular heart disease. The natural history of untreated significant TR portends an unfavourable outcome, but only a minority of patients is currently referred for surgical treatment. Organic TR (caused by primary abnormality of the leaflets) is relatively infrequent whereas secondary or functional TR (caused by dilatation of the tricuspid annulus, right ventricle [RV] and right atrium) is the predominant mechanism. The success of transcatheter therapies for left valvular heart disease over the last decade, has fuelled similar development of novel transcatheter devices for the treatment of TR...

Background: Antibiotic resistance poses a significant threat to patients suffering from infectious diseases. Early readings of antibiotic susceptibility test (AST) results could be of critical importance to ensure adequate treatment. Disc diffusion is a well-standardized, established and cost-efficient AST procedure; however, its use in the clinical laboratory is hampered by the many manual steps involved, and an incubation time of 16-18 h, which is required to achieve reliable test results...

Background: Dual plane breast augmentation is a technical variation of the submuscular plane described as a technique that reduces contour deformities due to contraction of the pectoralis major muscle and lower risk of double-bubble deformity associated with breast ptosis. Despite improvement in the aesthetic aspect, there is still no consensus whether this technique affects the function of the pectoralis major muscle. Objectives: The aim of this study was to correlate functional with volumetric changes associated with dissection of the muscle origin in submuscular breast augmentation...

BACKGROUND: Bilateral axillo-breast approach robotic thyroidectomy (BABA RT) is frequently performed and has excellent cosmetic results. However, there has been concern that subcutaneous tunneling in construction of the operation field might interfere with subsequent breast imaging. In this study, we evaluated whether BABA RT interferes with breast imaging by evaluating serial perioperative results of mammography and ultrasonography. METHODS: We selected female patients who underwent BABA RT between 2008 and 2012, and who also had mammography or ultrasonography pre- and postoperatively, and compared the results of pre- and postoperative imaging...

OBJECTIVE: Treatment response assessment in high-grade gliomas uses contrast enhanced T1-weighted MRI, but is unreliable. Novel advanced MRI techniques have been studied, but the accuracy is not well known. Therefore, we performed a systematic meta-analysis to assess the diagnostic accuracy of anatomical and advanced MRI for treatment response in high-grade gliomas. METHODS: Databases were searched systematically. Study selection and data extraction were done by two authors independently...
