INTRODUCTION: Genitalia are linked to self-esteem and male sexual identity, especially among young men, who sometimes require a surgical procedure to acquire more confidence. Among the surgical procedures requested for aesthetical purposes, circumcision is one of the most popular. Although it can be considered to be a simple surgical practice, it may cause severe complications such as penile skin necrosis. PRESENTATION OF CASE: We report a case of a catastrophic situation after a circumcision performed on a 27-year-old HIV positive man resulted in a drastic reduction in the length of the penile shaft due to extensive skin loss; this was subsequently restored using dartos-fascio-myo-cutaneous flaps...

Painful stimulation of the hand results in an inhibitory response in the hand muscles known as the cutaneous silent period (CSP). In this study, we employed probability- and frequency-based analysis methods to examine the CSP induced by laser stimuli. Subjects were asked to contract their first dorsal interosseous muscle so that selected motor units discharged at a rate of about 8Hz. Laser pulses were delivered to the palm of the hand, and reflex responses were recorded. The stimuli generated CSP in all test subjects...

There is some evidence that glutamate (Glu) acts as a signaling molecule at vertebrate neuromuscular junctions where acetylcholine (ACh) serves as a neurotransmitter. In this study, performed on the cutaneous pectoris muscle of the frog Rana ridibunda, Glu receptor mechanisms that modulate ACh release processes were analyzed. Electrophysiological experiments showed that Glu reduces both spontaneous and evoked quantal secretion of ACh and synchronizes its release in response to electrical stimulation. Quisqualate, an agonist of ionotropic α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic receptors and metabotropic Group I mGlu receptors, also exerted Glu-like inhibitory effects on the secretion of ACh but had no effect on the kinetics of quantal release...

BACKGROUND: Recent advancements in computed tomography have enabled the diagnosis of naso-orbito-ethmoid (NOE) fractures to be made in much greater detail. Surgical access to the upper nasofrontal buttress in NOE fractures, however, has remained unchanged over the past decades. All approaches to these fractures using skin incisions have individual drawbacks. The transcaruncular approach is free of the drawbacks of the cutaneous approaches. We further extended the transcaruncular approach for the treatment of NOE and Le Fort II fractures...

Leishmaniasis is a disease caused by the Leishmania parasites. The two common forms of leishmaniasis are cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL). VL is the more severe of the two and, if untreated, may become fatal. The hallmark of VL is the formation of granuloma in the liver or the spleen. In this paper, we develop a mathematical model of the evolution of granuloma in the liver. The model is represented by a system of partial differential equations and it includes migration of cells from the adaptive immune system into the granuloma; the rate of the influx is determined by the strength of the immune response of the infected individual...

BACKGROUND: Thrombotic cutaneous gangrene is a rare extra-intestinal manifestation of ulcerative colitis with a severe prognosis. CASE REPORT: A 35-year-old woman with a 7-year history of ulcerative colitis presented with extensive ecchymotic lesions that began a few hours earlier. On examination, she was febrile with multiple necrotic lesions. Skin biopsy showed multiple microthrombi in the dermal vessels. A diagnosis of thrombotic cutaneous gangrene was established...

Electrochemotherapy is a therapeutic option for the treatment of cutaneous and subcutaneous metastases from melanoma and other tumors. The procedure consists of the administration of anticancer drugs followed by locally applied electrical impulses to achieve an effect known as electroporation, which facilitates entry into the cytosol of drugs that cannot cross the cell membrane. The aim of this review is to evaluate the evidence that supports the use of electrochemotherapy as a therapeutic strategy in melanoma...

Apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) is an important adaptor protein for inflammasome activation, mediating the secretion of protumorigenic innate cytokines. However, ASC is also known to trigger apoptosis in tumor cells, acting as a tumor-suppressor gene, which is lost in several human cancers. The aim of this study was to evaluate the clinical significance of ASC in human cutaneous squamous cell carcinoma (SCC). Initially, ASC expression was immunohistochemically evaluated in non-metastic and metastatic SCC...

Cutaneous leishmaniasis affects nearly 0.7 to 1.3 million people annually. Treatment of this disease is difficult due to lack of appropriate medication and the growing problem of drug resistance. Natural compounds such as coumarins serve as complementary therapeutic agents in addition to the current treatment modalities. In this study, we have performed an in-silico screening of the coumarin derivatives and their anti-leishmanial properties has been explored both in-vitro and in-vivo. One of the compounds (compound 2) exhibited leishmanicidal activity and to further study its properties, nanoliposomal formulation of the compound was developed...

Importance: Cutaneous surgery is performed by otolaryngologists, plastic surgeons, oculoplastic surgeons, dermatologic surgeons, and some primary care physicians. Practice gaps exist among cutaneous surgeons, as do differences in how different physicians approach preoperative, intraoperative, and postoperative decision-making. Objective: To present the newest and best evidence to close common practice gaps in cutaneous surgery. Evidence Review: We performed a detailed search of peer-reviewed publications that were identified through a search of PubMed/MEDLINE (January 1, 2000, through June 30, 2016) using the literature search terms "cutaneous surgery," "Mohs micrographic surgery," "plastic surgery," in combination with "safety," "cost," "anesthesia," "anti-coagulation," "bleeding," "pain," "analgesia," "anxiety," or "infection," among others...

BACKGROUND: Contact dermatitis can be defined as an inflammatory process affecting the skin surface and induced by contact with chemical, physical and/or biotic agents in the environment. It causes lesions to skin, mucosae and semi-mucosae by means of allergic and irritant pathogenic mechanisms. Among the main triggers of contact dermatitis in the pediatric age are chemical or physical agents, which cause irritant contact dermatitis (ICD), and sensitizers, which cause a tissue damage through an allergic mechanism (allergic contact dermatitis [ACD])...

Epigenetic modifications are functionally involved in gene expression regulation. In particular, histone posttranslational modifications play a crucial role in functional chromatin organization. Several drugs able to inhibit or stimulate some families of proteins involved in epigenetic histone regulation have been found, a number of which are FDA-approved for the treatment of cutaneous T-cell lymphoma or are in phase I/II/III clinical trials for solid tumors. Although some protein families, such as histone deacetylases and their inhibitors, are well characterized, our understanding of histone lysine demethylases is still incomplete...

Recent advances in genetic technology have found their way into clinical dermatology. Approximately one third of all hereditary disorders show characteristic cutaneous findings. Moreover, human skin easily provides samples for studying the mechanisms of genetic mosaicism, as well as the underlying functional defects due to mutated proteins. Diagnosing hereditary skin disorders remains, however, a challenging task due to the rarity of genodermatoses and their diversity, overlapping or heterogeneous phenotypes, huge amount of new information, and complicated nomenclature and classifications...
