INTRODUCTION: Tuberculosis contacts are candidates for active and latent tuberculosis infection screening and eventual treatment. However, many losses occur in the different steps of the contacts' cascade of care. Reasons for this are poorly understood. OBJECTIVE: To describe the different steps where losses in the contact cascade occur and to explore knowledge and attitudes regarding tuberculosis transmission/prevention and perceptions about tuberculosis services in order to understand the reasons for losses from the tuberculosis service users' perspective...

Between 20 and 45% of women aged over 65 years of age will develop one or more foot problems, which, although not specific to older women, are more common in that age group than in younger women. These include structural defects of the toes including hallux valgus, hammer, mallet or claw toes, skin disorders, fungal infection of the toes and toe nails, thickened toe nails, ulcers, fissures or cracks between the toes, corns and calluses, flat or high-arched feet. Foot pain is common and may be associated with other co-morbid diseases of the foot...

BACKGROUND: Chronic and recalcitrant wounds present a significant therapeutic challenge. Amniotic tissues contain many regenerative cytokines, growth factors, and extracellular matrix molecules including proteoglycans, hyaluronic acid, and collagens I, III, and IV. Dehydrated amnion/chorion grafts are currently used to treat a variety of wounds such as diabetic foot ulcers and burns. OBJECTIVE: The investigators hypothesized that processing methodologies, dehydration, and hypothermic processing and storage of amniotic tissues would affect overall quality of wound healing; they compared dehydrated amnion/chorion (dHACM) grafts to a novel hypothermically stored amniotic membrane (HSAM) graft in a full-thickness rat wound model...

7-Aza-bicyclo-[2.2.1]heptane (7-aza-norbornane) is a bridged heterocyclic nucleus found in epibatidine, the alkaloid isolated from the skin of the tropical poison frog Epipedobates tricolor. Since epibatidine is known as one of the most potent acetyl-choline nicotinic receptor agonists, a plethora of literature has been devoted to this alkaloid. However, there are no structural data on the unsubstituted 7-aza-norbornane, the parent bicyclic ring of epibatidine and its derivatives. We herein present the structural characterization of the 7-aza-bicyclo-[2...

Glaucoma leads to blindness but there are diagnostic and therapeutic developments that aid ophthalmologists in the improved mangement of the disease compared to the past. Known risk factors such as age, myopia, dark pigmented skin, genetics, and elevated intraocular pressure play an important role for the individual patient's prognosis, and many yet unknown or not sufficiently investigated risk factors come along. The structured examination of the optic nerve head is crucial for the clincial diagnosis by the ophthalmologist...

REVIEW
Peng Li, Guoyao Wu
Glycine, proline, and hydroxyproline (Hyp) contribute to 57% of total amino acids (AAs) in collagen, which accounts for one-third of proteins in animals. As the most abundant protein in the body, collagen is essential to maintain the normal structure and strength of connective tissue, such as bones, skin, cartilage, and blood vessels. Mammals, birds, and fish can synthesize: (1) glycine from threonine, serine, choline, and Hyp; (2) proline from arginine; and (3) Hyp from proline residues in collagen, in a cell- and tissue-specific manner...

The free radical or oxidative stress theory of aging postulates that senescence is due to an accumulation of cellular oxidative damage, caused largely by reactive oxygen species (ROS) that are produced as by-products of normal metabolic processes in mitochondria. The oxidative stress may arise as a result of either increased ROS production or decreased ability to detoxify ROS. The availability of the mitochondrial NADPH pool is critical for the maintenance of the mitochondrial antioxidant system. The major enzyme responsible for generating mitochondrial NADPH is mitochondrial NADP(+)-dependent isocitrate dehydrogenase (IDH2)...

Prevention of aging is mainly obtained through appropriate health practices, modulated by the genetic causes of aging. Causes of facial structural aging include gravity, volume loss, contraction of the mimic muscles and obviously biological aging of tissues. Among the very numerous new surgical technique of facial rejuvenation, we could point out: for the frontal region, obviously we are focus on the endoscopic and non-endoscopic frontal lifts. But also, we should note the transcutaneous Brow Shaping which with a well defined, step by step technique is indeed a simple way to improve a possible difficult situation; concerning the mid-face lift, as the main risk is the secondary eyelid malposition, a high Smas or a temporo-malar lift can be performed...

BACKGROUND: A decision-to-delivery interval (DDI) of no more than 20 minutes has long been considered a requirement for cesarean sections, even though there have hardly been any studies on this topic. We retrospectively investigated data relevant to DDI for emergency cesarean sections performed for the most common indications, namely, suspected and documented fetal asphyxia. METHODS: We analyzed data on emergency in-hospital cesarean sections in the period 2008-2015...

BACKGROUND: Tsetse flies (genus Glossina) are large blood-sucking dipteran flies that are important as vectors of human and animal trypanosomiasis in sub-Saharan Africa. Tsetse anatomy has been well described, including detailed accounts of the functional anatomy of the proboscis for piercing host skin and sucking up blood. The proboscis also serves as the developmental site for the infective metacyclic stages of several species of pathogenic livestock trypanosomes that are inoculated into the host with fly saliva...

BACKGROUND: The usual stereotypical dermoscopic pattern associated with dermatofibromas is a pigment network and central white patch. However, this pattern may be difficult to diagnose in some variant cases. We aimed to describe dermoscopic patterns of dermatofibroma according to its histopathological subtypes, with special emphasis on new and rare dermoscopic features. METHODS: This prospective study, which was conducted between September 2015 and May 2016 in the Department of Dermatology, University Hospital Hassan II, Fez, Morocco, included 100 cases of dermatofibroma confirmed on clinical and histological grounds...

The extracellular matrix has drawn considerable interest in tissue engineering not only acts as a bioactive three-dimensional scaffold but also regulates cell behaviors through providing biochemical signals. Extracellular matrix-based biomaterials, mainly derived from xenogeneic tissues, have shown positive outcomes in promoting cutaneous wound healing. However, such extracellular matrices only contain low doses of growth factors, which limit their therapeutic efficiency. Recent reports demonstrated that cell sheets made from mesenchymal stem cell can accelerate wound repair through enhanced re-epithelialization and angiogenesis, but its clinical translation is hindered by several limitations, such as the risk of aberrant immune responses and cost implications...

Cortexolone-17α-propionate (CP) is a topically active antiandrogen useful in the treatment of skin disorders. In the solid state, three anhydrous forms of this drug (CPI, CPII and CPIII) occurr, together with one hydrated crystal (CPW). The single crystal structure of the monohydrated phase, CPW, compared with that of the anhydrous form CPIII, shows a markedly different solid state behavior. These latter pseudopolymorphic forms have also been fully characterized by spectroscopic methods.

Split-thickness skin grafting (STSG) is the current gold standard for treatment of extensive burn and traumatic skin injuries. However, STSG is limited by donor-site morbidity and availability, and often leads to scarring and wound contracture. Furthermore, these thin grafts lack dermal elements such as nerves and adnexa which are important in recapitulating normal skin function. Methods of fractional skin replacement either as minced STSGs or microscopic skin tissue columns (MSTCs) have been proposed, though these techniques have not been fully-characterized and lack evidence of regenerated adnexal structures...
