Inflammatory myofibroblastic tumors (IMTs) are uncommon breast lesions that consist of spindle cells accompanied by plasma cell-rich inflammatory infiltration, which may mimic breast cancer clinico-radiologically. A woman aged 38 years with a breast mass was referred to our general surgery clinic. The physical examination revealed a mass with irregular borders in the upper outer quadrant of the left breast. In mammography, the lesion was 15 mm in diameter with a spheric form and high density. Ultrasonographically, the mass was solid, heterogeneous, and hypoechoic with posterior enhancement...

Only few tissues lack lymphatic supply, such as the CNS or the inner eye. However, if the scleral border is compromised due to trauma or tumor, lymphatics are detected in the eye. Since the situation in the optic nerve (ON), part of the CNS, is not clear, the aim of this study is to screen for the presence of lymphatic markers in the healthy and lesioned ON. Brown Norway rats received an unilateral optic nerve crush (ONC) with defined force, leaving the dura intact. Lesioned ONs and unlesioned contralateral controls were analyzed 7 days (n = 5) and 14 days (n = 5) after ONC, with the following markers: PDGFRb (pericyte), Iba1 (microglia), CD68 (macrophages), RECA (endothelial cell), GFAP (astrocyte) as well as LYVE-1 and podoplanin (PDPN; lymphatic markers)...

REVIEW
Miguel Trelles Centurion, Rafael Van Den Bergh, Henry Gray
PURPOSE OF REVIEW: Disasters and armed conflicts are characterized by high numbers of trauma cases, and occur mainly in developing countries where the healthcare response is already impaired, resulting in an inadequate response. Aside of the trauma cases, other surgical health conditions are also still present and require urgent care. Surgical care needs are different from context to context and depend on local means and capabilities. RECENT FINDINGS: Doctors without Borders (MSF) has proven that even in precarious situations, safe administration of anesthesia is possible, and the "do no harm" principle can and must be upheld...

Porokeratosis is a skin disorder clinically characterized by annular plaques with keratotic borders resembling the Great Wall of China and histopathologically by cornoid lamellae. The disease has several clinical variants. Porokeratosis ptychotropica, which has recently become part of these variants, is quite rare and little known. The entity is characterized by verrucous plaques - which may resemble a psoriasis plaque - that affect the regions of the buttocks, most commonly the gluteal cleft, with or without extremity involvement...

Cardiac cells are subjected to mechanical and electrical forces, which regulate gene expression and cellular function. Therefore, in vitro electromechanical stimuli could benefit further integration of therapeutic cells into the myocardium. Our goals were (a) to study the viability of a tissue-engineered construct with cardiac adipose tissue-derived progenitor cells (cardiac ATDPCs) and (b) to examine the effect of electromechanically stimulated cardiac ATDPCs within a myocardial infarction (MI) model in mice for the first time...

BACKGROUND: Injuries of the marginal mandibular nerve (MMN) of the facial nerve result in paralysis of the lower lip muscle depressors and an asymmetrical smile. Nerve reconstruction, when possible, is the method of choice; however, in cases of long nerve gaps or delayed nerve reconstruction, conventional nerve repairs may be difficult to perform or may provide suboptimal outcomes. Herein, we investigate the anatomical technical feasibility of transfer of the platysma motor nerve (PMN) to the MMN for restoration of lower lip function, and we present a clinical case where this nerve transfer was successfully performed...

Dong Cheol Lee, Se Youp Lee
BACKGROUND: Several inferior oblique (IO) weakening methods exist for correction of superior oblique palsy (SOP). A previously reported method involved recession and anteriorization according to IO overaction (IOOA) grade, which might be subjective and cause upgaze limitation and opposite vertical strabismus. Therefore, this study attempted to examine the efficacy of modified graded recession and anteriorization of the IO muscle in correction of unilateral SOP without resulting in upgaze limitation or opposite vertical strabismus...

Defects in the fusion of facial buds can result from an anomaly in tissue development or apoptosis, or both. Our working hypothesis was that anomalies in the development of tissues could be caused by a genetic angiogenic defect. Our main objective was to design a reproducible experimental model to study the expression of angiogenic genes in the borders of cleft lips with or without cleft palate. We therefore prospectively studied seven non-syndromic patients, three with a cleft lip (2 right, 1 left), and four with a cleft lip and palate (1 bilateral, 2 right, 1 left), with no CGH (comparative genomic hybridisation) array, who had primary operations to repair their clefts...

The unprecedented demands of patient and population priorities created by globalization and escalating health and social inequities will not be met unless medical education changes. Educators have failed to move fast enough to create an education framework that meets current population needs. A new common set of professional values around global social accountability is necessary. Education borders must be broken down at three levels-societal-institutional, interpersonal, and individual.At a societal-institutional level, global health must be embraced as part of a philosophy of population needs, human rights, equity, and justice...
