Staphylococcal scalded skin syndrome is an exfoliating skin disease which primarily affects children. Differential diagnosis includes toxic epidermal necrolysis, staphylococcal scalded skin syndrome, epidermolysis bullosa, and Stevens-Johnson syndrome. Staphylococcal scalded skin syndrome primarily affects children and can cause serious morbidity. In this case report we highlight the case of a 4-year-old Caucasian boy. Diagnostic and therapeutic challenges are discussed. Differential diagnoses are considered and therapy is described and discussed. The latest treatment options are used and described. Successful results are achieved in this case due to timely and correct management. Some therapeutic options are widely used without thorough research bases. This case report highlights staphylococcal scalded skin syndrome and its treatment, and future challenges. Further research is warranted and this case report aims to further research in exfoliating skin disorders.

Full Text Available Purpose : Staphylococcal scalded skin syndrome (SSSS is a relatively uncommon superficial blistering skin disease that is due to Staphylococcus aureus. We had experienced a regional outbreak of SSSS over 3 years in healthy children. Methods : We retrospectively reviewed the medical records of those patients diagnosed as SSSS. Most of neonatal cases were nosocomial infections and excluded from the analysis. The clinical features, laboratory findings, the isolation and antibiotic resistance of S. aureus, the antibiotic management and other supportive treatments were analyzed. Results : Fifty-five patients with SSSS were admitted to our hospital from October 2001 to September 2004. The median age of patients was 3.0 years. Of the 55 patients, 9 were the generalized type, 13 were the intermediate type and 33 were the scarletiniform rash. All the patients were living in neighborhood of the Jinju area. S. aureus were isolated from 9 of the patients and all of the isolated S. aureus were methicillin resistant. All the patients except two were treated with intravenous flocloxacillin or nafcillin and/or cefotaxime. All the patients recovered during the follow-up period of 2 to 3 weeks. Conclusion : We experienced a regional outbreak of SSSS in previous healthy children. Further study for finding the carriers of S. aureus caused SSSS and preventing the spread of this disease is needed. Additionally, guidelines for treating SSSS due to methicillin resistant S. aureus should be established.
Staphylococcal scalded skin syndrome (SSSS) is a toxin-mediated exfoliating skin condition predominated by desquamation and blistering. Neonatal outbreaks have already been reported; however, our outbreak highlights the potential for SSSS following neonatal health promotion measures such as intra-muscular vitamin K administration and metabolic screening (heel prick) as well as effective case containment measures and the value of staff screening. Between February and June 2007, five confirmed cases of neonatal SSSS were identified in full-term neonates born in an Irish regional maternity hospital. All infants were treated successfully. Analysis of contact and environmental screening was undertaken, including family members and healthcare workers. Molecular typing on isolates was carried out. An outbreak control team (OCT) was assembled and took successful prospective steps to prevent further cases. All five Staphylococcus aureus isolates tested positive for exfoliative toxin A, of which two distinct strains were identified on pulsed-field gel electrophoresis analysis. Two cases followed staphylococcal inoculation during preventive measures such as intra-muscular vitamin K administration and metabolic screening (heel prick). None of the neonatal isolates were methicillin resistant. Of 259 hospital staff (70% of staff) screened, 30% were colonised with S. aureus, and 6% were positive for MRSA carriage. This is the first reported outbreak of neonatal SSSS in Ireland. Effective case containment measures and clinical value of OCT is demonstrated. Results of staff screening underlines the need for vigilance and compliance in hand disinfection strategies in maternity hospitals especially during neonatal screening and preventive procedures.

A male term neonate, at day 23 of life, presented with vesicular lesions over the trunk, which spread to allover the body on the next day. Five days later, he started developing blistering of the skin over the trunk and extremities, which subsequently ruptured, leaving erythematous, tender raw areas with peeling of the skin. The mother had vesicular eruptions, which started on the second day of delivery and progressed over the next 3 days. Subsequently, similar eruptions were noticed in two of the siblings before affecting the neonate. On the basis of the exposure history and clinical picture, a diagnosis was made of varicella infection with staphylococcal scalded skin syndrome (SSSS). The blood culture and the wound surface culture grew Staphylococcus aureus. Treatment included intravenous fluid, antibiotics, acyclovir and wound care. However, after 72 h of hospitalisation, the neonate first developed shock, refractory to fluid boluses, vasopressors and catecholamine along with other supports; and he then succumbed. In all neonates, staphylococcal infection with varicella can be fatal due to SSSS, the toxic shock syndrome or septicaemia.
Full Text Available CONTEXT: Staphylococcal scalded skin syndrome is an exfoliative skin disease. Reports of this syndrome in newborns caused by methicillin-resistant Staphylococcus aureus are rare but, when present, rapid diagnosis and treatment is required in order to decrease morbidity and mortality. CASE REPORT: A premature newly born girl weighing 1,520 g, born with a gestational age of 29 weeks and 4 days, developed staphylococcal scalded skin syndrome on the fifth day of life. Cultures on blood samples collected on the first and fourth days were negative, but Pseudomonas aeruginosa and Enterococcus sp. (vancomycin-sensitive developed in blood cultures performed on the day of death (seventh day, and Pseudomonas aeruginosa and Serratia marcescens were identified in cultures on nasopharyngeal, buttock and abdominal secretions. In addition to these two Gram-negative bacilli, methicillin-resistant Staphylococcus aureus was isolated in a culture on the umbilical stump (seventh day. The diagnosis of staphylococcal scalded skin syndrome was based on clinical criteria.

Staphylococcal scalded skin syndrome (SSSS) is a blistering skin condition caused by exfoliative toxin-producing strains of Staphylococcus aureus. Outbreaks of SSSS in maternity settings are rarely reported. We describe an outbreak of SSSS that occurred among neonates born at a maternity unit in England during December 2012 to March 2013. Detailed epidemiological and microbiological investigations were undertaken. Eight neonates were found to be infected with the outbreak strain of S. aureus, of spa type t346, representing a single pulsotype. All eight isolates contained genes encoding exfoliative toxin A (eta) and six of them contained genes encoding toxin B (etb). Nasal swabs taken during targeted staff screening yielded a staphylococcal carriage rate of 21% (17/80), but none contained the outbreak strain. Mass screening involving multi-site swabbing and pooled, enrichment culture identified a healthcare worker (HCW) with the outbreak strain. This HCW was known to have a chronic skin condition and their initial nasal screen was negative. The outbreak ended when they were excluded from work. This outbreak highlights the need for implementing robust swabbing and culture methodswhen conventional techniques are unsuccessful in identifying staff carrier(s). This study adds to the growing body of evidence on the role of HCWs in nosocomial transmission of S. aureus.

Over a three-month period, 13 neonates developed staphylococcal scalded skin syndrome (SSSS) in a maternity unit, between four and 18 days after their birth. An epidemiological and descriptive study followed by a case-control study was performed. A case was defined as a neonate with blistering or peeling skin, and exfoliative toxin A Staphylococcus aureus positive cultures. Controls were selected at random from the asymptomatic, non-colonized neonates born on the same day as the cases. All staff members and all neonates born during the outbreak period were screened for carriage by nasal swabs and umbilical swabs, respectively. S. aureus isolates were polymerase chain reaction (PCR) screened for etA gene and genotyped by pulsed-field gel electrophoresis (PFGE). Two clusters of eight and five cases were identified. Receiving more than one early umbilical care procedure by the same ancillary nurse was the only risk factor identified in the case-control study (odds ratio=15, 95% confidence intervals 2-328). The ancillary nurse suffered from chronic dermatitis on her hands that favoured S. aureus carriage. Exfoliative-toxin-A-producing strains, as evidenced by PCR and indistinguishable by PFGE, were isolated from all but one of the SSSS cases, from four asymptomatic neonates, from two staff members and from the ancillary nurse's hands. Removal of the ancillary nurse from duty, infection control measures (isolation precautions, chlorhexidine handwashing and barrier protections), and treatment of the carriers (nasal mupirocin and chlorhexidine showers) led to control of the epidemic. In conclusion, this study emphasizes the need for tight surveillance of chronic dermatitis in healthcare workers.

The aims of this study were to identify the source and the transmission pathway for a Staphylococcal Scalded Skin Syndrome (SSSS) outbreak in a maternity setting in Italy over 2 months, during 2014; to implement appropriate control measures in order to prevent the epidemic spread within the maternity ward; and to identify the Methicillin-Resistant Staphylococcus aureus (MRSA) epidemic clone. Epidemiological and microbiological investigations, based on phenotyping and genotyping methods, were performed. All neonates involved in the outbreak underwent clinical and microbiological investigations to detect the cause of illness. Parents and healthcare workers were screened for Staphylococcus aureus to identify asymptomatic carriers. The SSSS outbreak was due to the cross-transmission of a rare clone of ST5-CA-MRSA-SCCmecV-spa type t311, exfoliative toxin A-producer, isolated from three neonates, one mother (from her nose and from dermatological lesions due to pre-existing hand eczema) and from a nurse (colonized in her nose by this microorganism). The epidemiological and microbiological investigation confirmed these as two potential carriers. A rapid containment of these infections was obtained only after implementation of robust swabbing of mothers and healthcare workers. The use of molecular methodologies for typing was able to identify all carriers and to trace the transmission.

The susceptibilities to antimicrobial agents of and distributions of antiseptic resistance genes in methicillin-resistant Staphylococcus aureus (MRSA) strains isolated between 1999 and 2004 in Japan were examined. The data of MRSA strains that are causative agents of impetigo and staphylococcal scalded skin syndrome (SSSS) were compared with those of MRSA strains isolated from patients with other diseases. The susceptibilities to antiseptic agents in MRSA isolates from patients with impetigo and SSSS were higher than those in MRSA isolates from patients with other diseases. The distribution of the qacA/B genes in MRSA strains isolated from patients with impetigo and SSSS (1.3%, 1/76) was remarkably lower than that in MRSA strains isolated from patients with other diseases (45.9%, 95/207). Epidemiologic typings of staphylococcal cassette chromosome mec (SCCmec) and pulsed-field gel electrophoresis (PFGE) showed that MRSA strains isolated from patients with impetigo and SSSS had type IV SCCmec (75/76), except for one strain, and 64.5% (49/76) of the strains had different PFGE types. In addition, the patterns of restriction digestion of all tested qacA/B plasmid in MRSA isolates having different PFGE types were identical. The results showed that a specific MRSA clone carrying qacA/B was not prevalent, but qacA/B was spread among health care-associated MRSA strains. Therefore, it was concluded that the lower distribution rate of qacA/B resulted in higher susceptibilities to cationic antiseptic agents in MRSA isolated from patients with impetigo and SSSS.

Second-degree scalding is a common dermatological injury. Inappropriate treatment methods in clinical practice always produce scarring, and can lead to skin cancer and other complications in the longer term. In this study optical coherence tomography (OCT) combined with a skin detector was used to monitor the response of second-degree scalded skin tissue irradiated by a CO2 laser. The process of treatment of second-degree scalding was systematically studied from the perspective of tissue optics. The OCT signal intensity was stronger within the whole recovery period in the experimental group undergoing CO2 laser treatment, and the attenuation coefficient (μt) returned to its original value in a shorter time. The results help us to understand tissue injury in a second-degree scald and may help improve the standard treatment.

Genetically feathered and featherless sibling broilers selected for matched BW were killed, scalded, and defeathered to determine the consequences of feathers and empty feather follicles on the recovery of bacteria from carcass breast skin. In trial 1, the vents of all carcasses were plugged and sutured before scalding to prevent the expulsion of cloacal contents during picking. In trial 2, half of the carcasses had their vents plugged and sutured. Immediately after defeathering, breast skin was aseptically removed, and bacteria associated with it were enumerated. In trial 1, the levels of bacteria recovered did not differ between feathered and featherless carcasses: Campylobacter log10 1.4 cfu/mL of rinse, coliform log10 1.8, Escherichia coli log10 1.6, and total aerobic bacteria log10 3.1. In trial 2, the carcasses that had vents plugged and sutured had lower levels of all four types of bacteria (differences of Campylobacter log10 0.7 cfu/mL, coliform log10 1.8, E. coli log10 1.7, and total aerobic bacteria log10 0.5) than those carcasses with open vents. The lower levels of bacteria recovered from carcasses with the vents plugged and sutured during picking enabled detection of small but significant differences between feathered and featherless carcasses. The level of coliform and E. coli recovered was slightly higher by log10 0.7 cfu for feathered carcasses, but featherless carcasses had marginally higher levels of total aerobic bacteria by log10 0.4 cfu. Feathered and featherless carcasses with open vents during picking did not differ in the levels of recovery of coliform, E. coli, and total aerobic bacteria from breast skin.

A comparison of two types of scalders was conducted to determine their effectiveness in reducing bacterial contamination of poultry carcasses. A conventional hot-water scalder and a prototype model of a steam scalder were tested under commercial conditions. Total plate counts from steam-scalded birds were significantly lower than the counts of water-scalded birds immediately after scalding and again after picking. No differences in the two methods could be found after chilling. Coliform counts from steam-scalded birds were significantly lower than the counts from water-scalded birds immediately after scalding. No significant differences in coliform counts were detected when the two scald methods were compared after defeathering and chilling.

The treatment of scald burns in children is still under discussion. The aim of the present study was to evaluate an optimised treatment regime for scald burns in children. Between 1997 and 2002, 124 children underwent surgical intervention due to burn injuries. Thirty-six out of these 124 children were enrolled into the evaluation of our recent treatment protocol. Twenty-two children with scald burns covering an average body surface area (TBSA) of 18.5% were treated by early excision and coverage with allogeneic keratinocytes in case of partial thickness lesions (keratinocyte group). Fourteen children with a TBSA of 17.2% were treated with autologous skin grafts alone (skin graft group). Both groups were comparable according to age, burn depth and affected TBSA. The complete clinical follow-up examination of at least 17 months was performed in 12 out of 22 children of the keratinocyte group and in 9 out of 14 patients of the comparative group. Visible scar formations were classified according to the Vancouver Scar Scale (VSS) in each patient. The use of allogeneic keratinocytes led to complete epithelialisation within 12 days in 20 of the 22 cases. No secondary skin grafting procedures had to be done. Skin take rate at the sixth postoperative day was 100% in the skin graft group. Blood transfusions were administered intraoperatively according to the clinical need of the patients by the responsible anaesthesiologist. The mean volume of blood, which had to be transfused was 63.9 ml in the keratinocyte group and significantly lower than the volume of 151.4 ml, which was administered in the skin graft group (p=0.04). At follow up the VSS observed in areas covered by keratinocytes was 2.33 on the average and therefore, significantly lower than the VSS of 5.22 in skin grafted areas of the comparative group (p=0.04). In children the use of cultivated keratinocytes in partial thickness scald burns is a procedure, which renders constantly reliable results. It minimizes the

In this research, two delivery methods (infusion pumping and local topical application were applied to deliver recombinant human erythropoietin (rHuEPO for skin regeneration. First, rHuEPO was given in deep second-degree scald injury sites in mice by infusion pump. Vascularization was remarkably higher in the rHuEPO pumping group than in controls. Second, local topical application of rHuEPO gel was given in deep second-degree scald injury sites in rats. Histological analysis showed that epithelialization rate was significantly higher in the rHuEPO gel-treated group than in controls. Immunohistochemical studies showed that the rHuEPO gel-treated group showed remarkably higher expression of skin regeneration makers than the control group. An accurate method for visualization and quantification of blood vessel networks in target areas has still not been developed up to this point, because of technical difficulties in detecting such thin blood vessels.

Previous examination in a small number of individuals with Williams syndrome (also referred to as Williams-Beuren syndrome) has shown subtly softer skin and reduced deposition of elastin, an elastic matrix protein important in tissue recoil. No quantitative information about skin elasticity in individuals with Williams syndrome is available; nor has there been a complete report of dermatologic findings in this population. To fill this knowledge gap, 94 patients with Williams syndrome aged 7-50 years were recruited as part of the skin and vascular elasticity (WS-SAVE) study. They underwent either a clinical dermatologic assessment by trained dermatologists (2010 WSA family meeting) or measurement of biomechanical properties of the skin with the DermaLab™ suction cup (2012 WSA family meeting). Clinical assessment confirmed that soft skin is common in this population (83%), as is premature graying of the hair (80% of those 20 years or older), while wrinkles (92%), and abnormal scarring (33%) were detected in larger than expected proportions. Biomechanical studies detected statistically significant differences in dP (the pressure required to lift the skin), dT (the time required to raise the skin through a prescribed gradient), VE (viscoelasticity), and E (Young's modulus) relative to matched controls. The RT (retraction time) also trended longer but was not significant. The biomechanical differences noted in these patients did not correlate with the presence of vascular defects also attributable to elastin insufficiency (vascular stiffness, hypertension, and arterial stenosis) suggesting the presence of tissue specific modifiers that modulate the impact of elastin insufficiency in each tissue. © 2014 Wiley Periodicals, Inc.
Skin regeneration with conical and hair follicle structure of deep second-degree scalding injuries via combined expression of the EPO receptor and beta common receptor by local subcutaneous injection of nanosized rhEPO

Although erythropoietin (EPO has a protective role in a wide range of organs and cells during ischemia and after trauma, it has been recently discovered that EPO is not tissue-protective in the common β subunit receptor (βCR knockout mouse. The protective capacity of EPO in tissue is mediated via a heteroreceptor complex comprising both the erythropoietin receptor (EPOR and βCR. However, proof of coexpression of these heterogenic receptors in regenerating skin after burns is still lacking.Methods: To understand the role of nanosized recombinant human erythropoietin (rhEPO in wound healing, we investigated the effects of subcutaneous injections of EPO on skin regeneration after deep second-degree scalding injuries. Our aim was to determine if joint expression of EPOR and βCR is a prerequisite for the tissue-protective effect of rhEPO. The efficiency in wound regeneration in a skin scalding injury mouse model was examined. A deep second-degree dermal scald injury was produced on the backs of 20 female Balb/c mice which were subsequently randomized to four experimental groups, two of which received daily subcutaneous injections of rhEPO. At days 7 and 14, the mice were sacrificed and the effects of rhEPO were

Full Text Available Ectodermal dysplasia-skin fragility syndrome (EDSFS is a rare autosomal recessive genodermatosis first described in 1997 by Mc Grath. EDSFS results from loss of function mutations in plakophilin-1 (PKP1. PKP1 is a structural component of desmosomes, cellcell adhesion complexes. It is also found as a nuclear protein in several cell types that are lack of desmosomes. In skin, however, PKP1 expression is confined mainly to suprabasal keratinocytes and the outer root sheath of hair follicules. Loss of function mutation in PKP1 leads to extensive skin fragility, bullae and erosions following minor trauma, focal keratoderma with painful fissures, alopecia, and nail dystrophy. In some patients hypohidrosis may also be seen. EDSFS is now considered as a specific suprabasal form of epidermolysis bullosa simplex. In this report we describe a 20 year old EDSFS case.

The effect of scalding and chilling procedures was evaluated on carcass and breast meat weight and yield in broilers. On 4 separate weeks (trials), broilers were subjected to feed withdrawal, weighed, and then stunned and bled in 4 sequential batches (n = 16 broilers/batch, 64 broilers/trial). In addition, breast skin was collected before scalding, after scalding, and after defeathering for proximate analysis. Each batch of 16 carcasses was subjected to either hard (60.0°C for 1.5 min) or soft (52.8°C for 3 min) immersion scalding. Following defeathering and evisceration, 8 carcasses/batch were air-chilled (0.5°C, 120 min, 86% RH) and 8 carcasses/batch were immersion water-chilled (water and ice 0.5°C, 40 min). Carcasses were reweighed individually following evisceration and following chilling. Breast meat was removed from the carcass and weighed within 4 h postmortem. There were significant (P defeathered eviscerated weights did not differ between the scalding and chilling treatments. During air-chilling all carcasses lost weight, resulting in postchill carcass yield of 73.0% for soft-scalded and 71.3% for hard-scalded carcasses, a difference of 1.7%. During water-chilling all carcasses gained weight, resulting in heavier postchill carcass weights (2,031 g) than for air-chilled carcasses (1,899 g). Postchill carcass yields were correspondingly higher for water-chilled carcasses, 78.2% for soft-scalded and 76.1% for hard-scalded carcasses, a difference of 2.1%. Only in trials 1 and 4 was breast meat yield significantly lower for hard-scalded, air-chilled carcasses (16.1 and 17.5%) than the other treatments. Proximate analysis of skin sampled after scalding or defeathering did not differ significantly in moisture (P = 0.2530) or lipid (P = 0.6412) content compared with skin sampled before scalding. Skin protein content was significantly higher (P defeathering. The hard-scalding method used in this experiment did not result in increased skin lipid loss either

Full Text Available Ectodermal dysplasia-skin fragility (EDSF syndrome is a rare and first described inherited disorder of desmosomes. It occurs due to loss-of-function mutations in PKP1 gene resulting in poorly formed desmosomes and loss of desmosomal and epidermal integrity. We report a case of a 2-year-old Indian male child who presented with palmoplantar hyperkeratosis with fissuring, short, sparse, and easily pluckable scalp hair, nail dystrophy, and multiple erosions over the skin. Skin biopsy showed epidermal hyperplasia with widening of intercellular spaces. His developmental milestones were delayed but intelligence was normal. Echocardiography, X-ray chest, and electrocardiogram were normal. Very few cases of this syndrome have been reported in the literature. We consider this as the first case report from India.

In a prospective study of 560 children treated for burns as in-patients over a period of four-and-a-half years in specialized hospitals responsible for the majority of burn cases in Kuwait, 388 patients (69%) had sustained scalds. The mean age of these 388 children, between 0 to 12 years, was 3.02 +/- 2.08, and male to female ratio 1.5 to 1. They were categorized into three age groups, first, up to 1 year comprised 17.5% cases, who were solely dependent on parents or childminder; second 2 to 5 years of age, who were inquisitive, independent, pre-school children, and constituted the majority of cases (73%), and third 6 to 12 years who were 9.5% school children. The pre-school children (2-5 years) thus formed a highly vulnerable group in the country. Accidents (99.4%) occurred at home and the kitchen being the commonest place. The hot water from pan and pots in the kitchen was the most common etiologic factor in 229 cases (59%), followed by tea/coffee 20.7%, soup 9.0%, hot oil 6.7%, and milk 4.6% patients. The most common circumstance was the child upsetting the pan of hot fluid in the kitchen. The mean total body surface areas of second and third degree burns were 14.21 +/- 9.66 (range 1 to 60%). The average length of stay in the hospital was 16.90 +/- 15.74 days, varying from one to 109 days. Thirty-nine children were ill prior to burn, and the commonest disease was respiratory tract infection. Three patients (0.8%) with 3rd degree burns were treated with primary excision and grafting, and 137 (35.3%) needed secondary skin grafting for residual burn wounds. Four patients (1%) died, one due to burn shock, two due to septicemia and one due to multiorgan failure. There is need for general awareness through public education, which may lead to the prevention of significant number of such accidents.

Peeling skin syndrome is a rare dermatosis characterized by spontaneous and painless peeling of the skin. The authors report two patients with history of spontaneous, asymptomatic, and noninflammatory peeling skin of the acral surfaces after soaking in water. On light microscopy, blisters were located in the mid layers of the stratum corneum, above the granular layer. Ultrastructural examination revealed increased intercellular lipids and abnormal, "moth-eaten," keratohyalin granules, but the authors were unable to determine whether the separation initiated within the horny cells or between adjacent cells. These patients represented a localized variant of peeling skin syndrome.

Granulomatous slack skin syndrome is a rare variant of cutaneous T-cell lymphoma (mycosis fungoides). It is characterized clinically by redundant skin folds, which show a predilection towards flexural areas such as the axilla and the groin. Histologically, it shows a granulomatous T-cell infiltrate and loss of elastic tissue. It has an indolent but progressive course; and is usually refractory to treatment. We report a unique case of slack skin syndrome, sparing the classical sites with rapid and unusual involvement of non-intertriginous areas.

Full Text Available Touraine Solente Gole syndrome is a rare hereditary syndrome of primary pachydermoperiostosis, with the characteristic triad of pachydermia (or elephant like skin, periostosis and acropachia. A 27-year-old patient presented with aesthetic deformity of forehead due to deep skin folds and coarsening of facial features due to progressive thickening of skin. Associated palmoplantar hyperkeratosis with broadened of finger and toe tips and digital clubbing were noticed. Dermatologic evaluation revealed cutis verticis gyrata of scalp, seborrhoeic hyperplasia of face and hyperhidrosis. Natural history of the disease and aetiopathogenesis were reviewed. Aesthetic correction of forehead through frontal rhytidectomy was attempted.
Full Text Available Pruni Cortex has been used to treat asthma, measles, cough, urticaria, pruritus, and dermatitis in traditional Korean medicine. The objective of this study was to investigate the effects of Prunus yedoensis Matsumura bark methanol extract (PYE on scald-induced dorsal skin wounds in rats. Scalds were produced in Sprague-Dawley rats with 100°C water and treated with 5% and 20% PYE (using Vaseline as a base, silver sulfadiazine (SSD, and Vaseline once a day for 21 days, beginning 24 hours after scald by treatment group allocation. The PYE-treated groups showed accelerated healing from 12 days after scald, demonstrated by rapid eschar exfoliation compared to the control and SSD groups. PYE-treated groups showed higher wound contraction rates and better tissue regeneration in comparison with the control group. Serum analysis showed that transforming growth factor beta 1 and vascular endothelial growth factor levels remained high or gradually increased up to day 14 in both PYE groups and then showed a sharp decline by day 21, implying successful completion of the inflammatory phase and initiation of tissue regeneration. These findings suggested that PYE is effective in promoting scald wound healing in the inflammation and tissue proliferation stages.

The skin, hair and nail changes in four distinct ectodermal dysplasia syndromes are compared and reviewed. These syndromes comprise Christ-Siemens-Touraine syndrome; ectrodactyly, ectodermal dysplasia and cleft lip/palate syndrome; ankyloblepharon-ectodermal defects-cleft lip/palate syndrome and Rapp-Hodgkin syndrome. A comprehensive overview of the dermatological signs and symptoms in these syndromes was generated from the database of the Ectodermal Dysplasia Network Germany, the clinical findings in the patients seen in our department and an extensive review of the literature. The findings included abnormalities of skin, sweating, hair and nails. These clinical findings are discussed in relation to the underlying molecular defects known to play a role in these four ectodermal dysplasia syndromes.

We report two brothers of Middle Eastern descent with consanguineous parents who present with numerous fragile, flaccid blisters on the hands and feet. In addition to spontaneous peeling, they can manually peel skin from acral areas without pain. The symptoms worsen with warm temperatures, excessive water exposure, and perspiration. Two biopsies from flaccid blisters on the feet were taken from the older brother, which revealed cleavage at the level of the stratum corneum. A diagnosis of acral peeling skin syndrome was made.
Full Text Available Abstract The body’s total antioxidant capacity represents a sum of the antioxidant capacity of various tissues/organs. A decrease in the body’s antioxidant capacity may induce oxidative stress and subsequent metabolic syndrome, a clustering of risk factors for type 2 diabetes and cardiovascular disease. The skin, the largest organ of the body, is one of the major components of the body’s total antioxidant defense system, primarily through its xenobiotic/drug biotransformation system, reactive oxygen species-scavenging system, and sweat glands- and sebaceous glands-mediated excretion system. Notably, unlike other contributors, the skin contribution is variable, depending on lifestyles and ambient temperature or seasonal variations. Emerging evidence suggests that decreased skin’s antioxidant and excretory functions (e.g., due to sedentary lifestyles and low ambient temperature may increase the risk for metabolic syndrome. This review focuses on the relationship between the variability of skin-mediated detoxification and elimination of exogenous and endogenous toxic substances and the development of metabolic syndrome. The potential role of sebum secretion in lipid and cholesterol homeostasis and its impact on metabolic syndrome, and the association between skin disorders (acanthosis nigricans, acne, and burn and metabolic syndrome are also discussed.

Full Text Available Ectodermal dysplasia/skin fragility syndrome (ED-SFS is a newly described autosomal recessive disorder characterized by skin fragility and blistering, palmoplantar keratoderma, abnormal hair growth, nail dystrophy, and occasionally defective sweating. It results from mutations in the PKP1 gene encoding plakophilin 1 (PKP1, which is an important component of stratifying epithelial desmosomes and a nuclear component of many cell types. Only 12 cases of this rare genodermatosis have been reported so far. We present an unusual case of ED-SFS in a 12-year boy who was normal at birth but subsequently developed skin fragility, hair and nail deformities, abnormal dentition, palmoplantar keratoderma, and abnormal sweating but no systemic abnormality.

Peeling skin syndrome is a rare genodermatosis characterized by variably pruritic superficial generalized peeling of the skin with several genes involved until now little is known about the association between FLG2 and peeling skin syndrome. We describe multiple family members from a consanguineous Saudi family with peeling skin syndrome. Next Generation Sequencing identifies a cosegregating novel variant in FLG2 c.632C>G (p.Ser211*) as a likely etiology in this family. Here, we reported on the clinical manifestation of homozygous loss of function variant in FLG2 as a disease-causing gene for peeling skin syndrome and expand the dermatology findings. © 2017 Wiley Periodicals, Inc.

Gerodermia osteodysplastica (GO) is a connective tissue disorder characterized by premature aging, wrinkled, and lax skin with reduced elasticity which is more marked on the dorsum of the hands and feet associated with hyperextensible joints and osteoporosis. The wrinkly skin syndrome (WSS) is characterized by wrinkled skin over the dorsum of the hands, feet, and abdomen; hyperextensible joints, particularly of the hands; intrauterine growth retardation; postnatal failure to thrive; and mental and developmental delay. We report on five children from two consanguineous Arab families with features overlapping both GO and WSS. All five children had similar dysmorphic facial features consisting of broad and prominent forehead, hypotelorism with epicanthal folds, prominent bulbous nose, flat malar region, and large protruding ears. All had wrinkling of the skin more marked on the dorsum of the hands, feet, and abdomen; hyperextensibility of the joints, particularly of the hands; and aged appearance. Intrauterine growth retardation, subsequent failure to thrive, developmental delay, and variable degree of osteoporosis was also present in all of them. The older three children developed progressive prognathism. We suggest that GO and WSS could represent variable manifestation of the same disorder. Copyright 2001 Wiley-Liss, Inc.

Generalized peeling skin syndrome (PSS) is a rare autosomal recessive dermatosis manifesting with continuous exfoliation of the stratum corneum. The inflammatory (type B) subtype of PSS was recently found to be caused by deleterious mutations in the CDSN gene encoding corneodesmosin, a major component of desmosomal junctions in the uppermost layers of the epidermis. In the present study, we assessed a 10-month-old baby, who presented with generalized superficial peeling of the skin. Using PCR amplification and direct sequencing, we identified the third PSS-associated mutation in CDSN, a homozygous 4 bp duplication in the second exon of the gene (c.164_167dup GCCT; p.Thr57ProfsX6). These data further support the notion that corneodesmosin deficiency impairs cell-cell adhesion in the upper epidermis, paving the way for an abnormal inflammatory response due to epidermal barrier disruption.

Acral peeling skin syndrome (APSS) is a rare, autosomal, recessive genodermatosis characterized by painless spontaneous exfoliation of the skin of the hands and feet at a subcorneal or intracorneal level. It usually presents at birth or appears later in childhood or early adulthood. Some cases result from mutations in the TGM5 gene that encodes transglutaminase 5, which has an important role in cross-linking cornified cell envelope proteins. We report a new APSS pedigree from Jordan that contains at least 10 affected family members, although sequencing of the TGM5 gene failed to disclose any pathogenic mutation(s). On the basis of probable consanguinity, we performed homozygosity mapping and identified areas of homozygosity on chromosomes 1, 6, 10, 13, and 16, although none of the intervals contained genes of clear relevance to cornification. APSS is a clinically and genetically heterogeneous disorder, and this Jordanian pedigree underscores the likelihood of still further heterogeneity. © 2011 Wiley Periodicals, Inc.
Full Text Available Goltz syndrome or Focal Dermal Hypoplasia is a rare multisystem disorder, involving all the three germ cell layers. The disease is thought to be inherited in X-linked dominant fashion with heterogeneous mutations of the PORCN gene at Xp11.23 locus. Majority of the cases are sporadic, mainly due to postzygotic somatic mutations. The clinical spectrum includes characteristic cutaneous manifestations, multiple skeletal anomalies, and involvement of the eyes, hair, nails, kidneys, and so on. Considerable variability is noted in the clinical expression of the disease probably due to genomic mosaicism. Around 300 cases of Goltz syndrome have been reported in the literature. Here, we report such a case with characteristic skin lesions, multiple bony defects, distinctive facial features, coloboma of iris, and bilateral hydronephrosis. The diagnosis was evident immediately after birth due to the characteristic clinical picture of the baby.

There is a paucity of evidence guiding management of small area partial thickness paediatric scalds. This has prevented the development of national management guidelines for these injuries. This research aimed to investigate whether a lack of evidence for national guidelines has resulted in variations in both management and outcomes of paediatric small area scalds across England and Wales (E&W). A national survey of initial management of paediatric scalds ≤5% Total Body Surface Area (%TBSA) was sent to 14 burns services in E&W. Skin graft rates of anonymised burns services over seven years were collected from the international Burns Injury Database (iBID). Average skin grafting rates across services were compared. Length of stay and proportion of patients receiving general anaesthesia for dressing application at each service were also compared. All 14 burns services responded to the survey. Only 50% of services had a protocol in place for the management of small area burns. All protocols varied in how partial thickness paediatrics scalds ≤5% TBSA should be managed. There was no consensus as to which scalds should be treated using biosynthetic dressings. Data from iBID for 11,917 patients showed that the average reported skin grafting rate across all burns services was 2.3% (95% CI 2.1, 2.6) but varied from 0.3% to 7.1% (P<0.001). Service provider remained associated with likelihood of skin grafting when variations in the %TBSA case mix seen by each service were controlled for (χ(2)=87.3, P<0.001). The use of general anaesthetics across services varied between 0.6 and 35.5% (P<0.001). The median length of stay across services varied from 1 to 3 days (P<0.001). A lack of evidence guiding management of small-area paediatric scalds has resulted in variation in management of these injuries across E&W. There is also significant variation in outcomes for these injuries. Further research is indicated to determine if care pathways and outcomes are linked. An evidence

Peeling skin syndrome (PSS) is a rare genodermatoses of probable autosomal recessive inheritance in Saudi Arabia, consanguinity of parents is common and consequently the occurrence of family disease, including that of the skin, is not uncommon. To characterize the clinical and pathological features of PSS in Saudi Arabia, we reviewed the medical records and clinical photographs of patients with recurring blistering diseases and conducted a histopathologic evaluation of skin biopsies to identify the site of cleavage. Eleven persons with PSS were seen at King Khalid National Guard Hospital in Jeddah between the years 1986 and 2005. Ages ranged between 2 and 15 years and there were 9 males (81.8%) and 2 females (18.2%). The most common presentation in the majority of patients was localized spontaneous peeling of the skin. Eight patients (72.8%) had a history of vesicles that were small, dry and peeled away. Trauma did no play role in blister formation. All patients were local from Bedouin tribes where a family history of a similar complaint was documented in 8 cases (72.7%). And consanguinity of marriage was evident on 6 patients (54.5%). Histological examination of the biopsies showed either intracorneal or superficial subcorneal cleavage above the granuler layer in all biopsied patients. Although rare, PSS occurs in Saudi Arabia and is most likely related to consanguinity of marriages. This disease is generally mild and is characterized by intrascorneal cleavage within the superficial epidermis. The disease should be recognized and not confused with other vasicobullous disease.

Peeling skin syndrome is an extremely rare genodermatosis of possible autosomal recessive inheritance, characterized by asymptomatic spontaneous exfoliation of the stratum corneum at a subcorneal or intracorneal level. It usually presents at birth or appears later in early childhood. The condition may be generalized or localized. Here we describe a case of localized continual skin peeling limited to the facial skin in a 6-month-old infant, with two other members of the family affected with the same condition. A few cases of localized skin peeling limited to the acral surfaces have been described in the literature, but a familial case of localized skin peeling limited to the facial skin has not been described before. We believe that our patient represents a new subtype of peeling skin syndrome, limited to the skin of the face.

Stiff skin syndrome (SSS) is a noninflammatory, fibrosing condition of the skin, often affecting the limb girdles. We present 4 new patients with SSS with largely unilateral, segmental distribution. To date, reported cases of SSS have been grouped based on generally accepted clinical and histopathologic findings. The purpose of this study was to analyze differences in clinical and histopathologic findings between previously reported SSS cases. This is a retrospective review of 4 new cases and 48 previously published cases of SSS obtained from PubMed search. Of 52 total cases, 18 (35%) were segmentally distributed and 34 (65%) were widespread. The average age of onset was 4.1 years versus 1.6 years for segmental versus widespread SSS, respectively. Limitation in joint mobility affected 44% of patients with segmental SSS and 97% of patients with widespread SSS. Histopathologic findings were common between the 2 groups. This was a retrospective study of previously published cases limited by the completeness and accuracy of the reviewed cases. We propose a distinct clinical entity, segmental SSS, characterized by a segmental distribution, later age of onset, and less severe functional limitation. Both segmental SSS and widespread SSS share common diagnostic histopathologic features. Copyright © 2016 American Academy of Dermatology, Inc. All rights reserved.
Full Text Available Abstract Background Marfan syndrome (MFS is a heritable connective tissue disorder caused by mutations in the fibrillin-1 gene. This syndrome constitutes a significant identifiable subtype of aortic aneurysmal disease, accounting for over 5% of ascending and thoracic aortic aneurysms. Results We used spotted membrane DNA macroarrays to identify genes whose altered expression levels may contribute to the phenotype of the disease. Our analysis of 4132 genes identified a subset with significant expression differences between skin fibroblast cultures from unaffected controls versus cultures from affected individuals with known fibrillin-1 mutations. Subsequently, 10 genes were chosen for validation by quantitative RT-PCR. Conclusion Differential expression of many of the validated genes was associated with MFS samples when an additional group of unaffected and MFS affected subjects were analyzed (p-value -6 under the null hypothesis that expression levels in cultured fibroblasts are unaffected by MFS status. An unexpected observation was the range of individual gene expression. In unaffected control subjects, expression ranges exceeding 10 fold were seen in many of the genes selected for qRT-PCR validation. The variation in expression in the MFS affected subjects was even greater.

There are very few porcine burn models that replicate scald injuries similar to those encountered by children. We have developed a robust porcine burn model capable of creating reproducible scald burns for a wide range of burn conditions. The study was conducted with juvenile Large White pigs, creating replicates of burn combinations; 50°C for 1, 2, 5 and 10 minutes and 60°C, 70°C, 80°C and 90°C for 5 seconds. Visual wound examination, biopsies and Laser Doppler Imaging were performed at 1, 24 hours and at 3 and 7 days post-burn. A consistent water temperature was maintained within the scald device for long durations (49.8 ± 0.1°C when set at 50°C). The macroscopic and histologic appearance was consistent between replicates of burn conditions. For 50°C water, 10 minute duration burns showed significantly deeper tissue injury than all shorter durations at 24 hours post-burn (p ≤ 0.0001), with damage seen to increase until day 3 post-burn. For 5 second duration burns, by day 7 post-burn the 80°C and 90°C scalds had damage detected significantly deeper in the tissue than the 70°C scalds (p ≤ 0.001). A reliable and safe model of porcine scald burn injury has been successfully developed. The novel apparatus with continually refreshed water improves consistency of scald creation for long exposure times. This model allows the pathophysiology of scald burn wound creation and progression to be examined. PMID:27612153

Full Text Available Context Hepatopathies can significantly influence both veins and arteries, these changes may cause some cutaneous stigmas, such as spider angioma (SA and some systemic vascular changes, such as those observed in hepatopulmonary syndrome (HPS. Based on this common pathophysiological root we can assume that the SA can be skin markers of HPS. Objective The objective of this study is to assess whether there is a relationship between the presence of SA and HPS. Methods Records of 40 patients with liver cirrhosis who underwent contrast echocardiography were evaluated, in which we researched the description of SA, physical examination, and other clinical and laboratory data. For diagnosis of HPS we use these signs of the disease: presence of liver disease (cirrhosis in the case, abnormalities in gas exchange by arterial blood gases, and evidence of pulmonary vasodilations by the contrast echocardiography. Results The SA were found in 21/40 (52.5% patients and hepatopulmonary syndrome in 9/40 (22.5%. The HPS was observed in 8/21 (38.1% of patients with SA and 1/19 (5.3% patients were without this sign (P<0.01. We found no statistically significant difference between the SA and the presence of HPS with sex or age. Patients with SA had a higher hypoxemia [PaO2 84.8 ± 11.5 mmHg and 19.8 ± 14.7 mmHg alveolar-arterial gradient of oxygen (AAG] than those without SA (PaO2 90.8 ± 10.7 mmHg and 10.9 ± 11.7 AAG mmHg (P<0.05. Conclusion Our findings show a correlation between the presence of SA and HPS, suggesting that the SA may be cutaneous markers of HPS.

Acral peeling skin syndrome (APSS, MIM #609796) is a rare autosomal recessive disorder characterized by superficial exfoliation and blistering of the volar and dorsal aspects of hands and feet. The level of separation is at the junction of the stratum granulosum and stratum corneum. APSS is caused by mutations in the TGM5 gene encoding transglutaminase-5, which is important for structural integrity of the outermost epidermal layers. The majority of patients originate from Europe and carry a p.(Gly113Cys) mutation in TGM5. In this study, we report both European and non-European families carrying other mutations in the TGM5 gene. In 5 patients, we found 3 novel mutations: c.1001+2_1001+3del, c.1171G>A and c.1498C>T. To confirm their pathogenicity, we performed functional analyses with a transglutaminase activity assay, determined alternative splicing by reverse-transcribed PCR analysis and used databases and in silico prediction tools. © 2015 John Wiley & Sons A/S.

This study was conducted to evaluate the efficacy of a scald additive, RP scald, to reduce Salmonella Typhimurium (ST) levels on inoculated poultry carcasses. The RP scald (contains sodium hydroxide) in a 1% solution has a pH of 11.0, which may reduce bacteria levels on carcasses. In this study, 600 broilers (Ross 708 straight run, 6 wk of age) with 300 broilers in each of 2 experimental trials were divided into 4 scald treatments (inoculated with ST) and 2 noninoculated groups. The treatment groups included 4 scald treatments (n = 50 per experimental group per trial): soft scald (SS; 50 degrees C for 90 s), soft scald with 1.0% added RP scald (SSRP), hard scald (56.6 degrees C for 45 s; HS), and hard scald with 1.0% added RP scald. The noninoculated groups (n = 50 per group per trial) are represented by SS0 and HS0. After defeathering, carcass rinses were collected for ST detection. Results indicated that inoculated broilers from hard scald with 1.0% added RP scald had the lowest Salmonella recovery, whereas carcasses from the SS treatment with no RP additive had the highest ST recovery. In trial 1, the SSRP was more effective in reducing ST than HS alone; however, this trend was not consistent. In trial 2, HS alone was more effective in ST reduction than SSRP. Within each scald temperature, the addition of RP scald increased ST reduction; therefore, RP scald may be effective in reducing ST on broiler carcasses in poultry scalder applications, particularly when hard scald temperatures are used.

Constitutional mismatch repair-deficiency (CMMR-D) syndrome is an autosomal recessive condition characterized by hematologic malignancies, brain tumors, Lynch syndrome-associated cancers and skin manifestations reminiscent of neurofibromatosis type 1 (NF1). In contrast to Lynch syndrome, CMMR-D syndrome is exceptionally rare, onset typically occurs in infancy or early childhood and, as described in this report, may also present with colonic polyposis suggestive of attenuated familial adenomatous polyposis (AFAP) or MUTYH associated polyposis (MAP). Here we describe two sisters with CMMR-D syndrome due to germline bi-allelic MSH6 mutations. Both sisters are without cancer, are older than typical for this condition, have NF1 associated features and a colonic phenotype suspicious for an attenuated polyposis syndrome. This report highlights the role of skin examinations in leading to an underlying genetic diagnosis in individuals with colonic adenomatous polyposis, but without mutations associated with AFAP or MAP. © 2010 John Wiley & Sons A/S.

Full Text Available Abstract Background Acral peeling skin syndrome is a rare autosomal recessive genodermatosis due to a missense mutation in transglutaminase 5. The skin peeling occurs at the separation of the stratum corneum from the stratum granulosum. Case presentation We present a case of two siblings who developed continuous peeling of the palms and soles from the first year of life. This peeling was more severe on the soles than palms and on younger sibling than elder sibling. Peeling is worsened by occlusion and sweating.

Acral peeling skin syndrome is a rare autosomal recessive genodermatosis due to a missense mutation in transglutaminase 5. The skin peeling occurs at the separation of the stratum corneum from the stratum granulosum. We present a case of two siblings who developed continuous peeling of the palms and soles from the first year of life. This peeling was more severe on the soles than palms and on younger sibling than elder sibling. Peeling is worsened by occlusion and sweating. Sporadic cases of Acral Peeling Skin Syndrome occur in African population. There is variability in time of presentation and clinical severity even within families.

Stiff skin syndrome is a rare sclerotic condition that presents during infancy or early childhood. It has an insidious chronic course and may lead to significant co-morbidity and reduced quality of life. Often, affected individuals experience impaired ambulation and immobilization related to joint involvement. Clinically, it may resemble other sclerotic diseases, so histopathological evaluation is necessary to establish a diagnosis. As it is a condition with limited treatment options, prompt diagnosis and early initiation of physical therapy is crucial to prevent joint restriction and maintain quality of life. We describe a case of a 7-year-old with stiff skin syndrome, and review the literature to discuss the clinical presentation, histological findings, and management of this condition.

The apple (Malus?domestica Borkh.) is one of the world?s most widely grown and valuable fruit crops. With demand for apples year round, storability has emerged as an important consideration for apple breeding programs. Soft scald is a cold storage-related disorder that results in sunken, darkened tissue on the fruit surface. Apple breeders are keen to generate new cultivars that do not suffer from soft scald and can thus be marketed year round. Traditional breeding approaches are protracted a...

A case of acquired skin fragility syndrome associated with hepatic disease in a 9-year-old, spayed female, domestic shorthair cat is described. The cat was admitted to the veterinary hospital of the University of São Paulo (Brazil) with a 6-week history of vomiting, inappetence and weight loss. Remarkable signs were weakness, lethargy and profound jaundice that had been present for 10 days according to the owner. On completion of the physical examination, when the cat was gently manipulated for blood collection the thoracic limb and interscapular skin tore. Liver enzymes and bilirubin levels were all above the normal range. On histological examination of skin and liver, Masson's trichrome stain showed collagen fibre alteration and major hepatocyte abnormalities. Findings were consistent with feline skin fragility syndrome associated with cholangiohepatitis and hepatic lipidosis. Copyright 2009 ESFM and AAFP. Published by Elsevier Ltd. All rights reserved.

Acral peeling skin syndrome (APSS) is a rare autosomal recessive condition, characterized by asymptomatic peeling of the skin of the hands and feet, often linked to mutations in the gene TGM5. However, more recently recessive loss of function mutations in CSTA, encoding cystatin A, have been linked with APSS and exfoliative ichthyosis. We describe the clinical features in two sisters with APSS, associated with a novel large homozygous deletion encompassing exon 1 of CSTA. © 2015 British Association of Dermatologists.

We present a case of 3-year-old Caucasian boy who developed monthly cyclic attacks of skin peeling of the palms and soles over 1.5 years. The skin peeling was associated with hypercalciuria. No mutation was present in TGM5 and CSTA genes, but the typical clinical picture and the biopsy from flaccid blisters on the feet confirmed the acral peeling skin syndrome (APSS). The possible associations of rare genetic disorders and metabolic conditions in the course of APSS need to be investigated.

The diagnostic evidence on clinical diseases and theoretic basis of moving cupping therapy were ex- plored in the paper. By the observation of the local reaction, such as skin appearance and color, the affected location, duration of sickness and nature of disease were judged. Different moving cupping methods were selected for different disorders. It was discovered that the property of syndromes should be recognized by the palpation on skin and muscle in the moving cupping therapy so that the pathogenesis and treating principle could be carefully determined. The moving cupping therapy is the important component of body surface therapy. Skin reaction observation and syndrome differentiation is the essential guidance of the moving cupping therapy.

One of the leading causes of scald burn injury in children is from hot soup, particularly prepackaged instant soups. The purpose of this study was to determine the demographic, socioeconomic, and situational factors that contribute to the incidence of scald burns in children. A 20-item questionnaire was given to the caregiver of children who were treated for scald burn injury at a pediatric burn center from July 2006 to March 2007. Questions included demographics (child age, gender, siblings, ethnicity), socioeconomic status (income, education), factors contributing to the injury (type of soup, child supervision, type of container), and location of injury. The mean age of the 78 children sustaining burn injury and completing the survey was 4.8 +/- 0.6 years. The majority of patients were girls (51%), and the most frequently involved ethnic group was Hispanic (44%). Households had a mean of 3.0 +/- 0.3 children in residence, and an income of less than $29,000/year (59%). The highest educational level achieved was high school for 73% of the parents. Prepackaged soup (65%) with a narrow base heated directly in the original container (46%) using the microwave (51%) was implicated in the majority of burns. Soup scald burns, especially from prepackaged instant soups, appear to predominate in lower income families with multiple children. The majority of injuries occur when the caregiver heats the soup in the original container using the microwave. Prevention of these types of injuries will require a two-pronged approach: educating families with multiple children and changing the soup packaging.

Fruit quality features resulting from ripening processes need to be preserved throughout storage for economical reasons. However, during this period several physiological disorders can occur, of which superficial scald is one of the most important, due to the development of large brown areas on the fruit skin surface. This study examined the variation in polyphenolic content with the progress of superficial scald in apple, also with respect to 1-MCP, an ethylene competitor interacting with the hormone receptors and known to interfere with this etiology. The change in the accumulation of these metabolites was further correlated with the gene set involved in this pathway, together with two specific VOCs (Volatile Organic Compounds), α-farnesene and its oxidative form, 6-methyl-5-hepten-2-one. Metabolite profiling and qRT-PCR assay showed these volatiles are more heavily involved in the signalling system, while the browning coloration would seem to be due more to a specific accumulation of chlorogenic acid (as a consequence of the activation of MdPAL and MdC3H), and its further oxidation carried out by a polyphenol oxidase gene (MdPPO). In this physiological scenario, new evidence regarding the involvement of an anti-apoptotic regulatory mechanism for the compartmentation of this phenomenon in the skin alone was also hypothesized, as suggested by the expression profile of the MdDAD1, MdDND1 and MdLSD1 genes. The results presented in this work represent a step forward in understanding the physiological mechanisms of superficial scald in apple, shedding light on the regulation of the specific physiological cascade.
Full Text Available We report four adult cases of atopic dermatitis (AD complicated by Sjogren's syndrome (SS. The patients fulfilled diagnostic criteria for AD and SS. All cases showed persistent itchy dry skin and eczematous lesions complicated by sicca symptoms including dry eyes and dry mouth with moderate joint pain. One case manifested annular erythema and another manifested widespread discoid erythema. To investigate the underlying cause of dry skin in these cases, sweating function was evaluated using a quantitative sudomotor axon reflex test (QSART in which the axon reflex is stimulated by acetylcholine iontophoresis. The sweating latency time was significantly prolonged in eczematous skin of AD and AD/SS compared to normal controls. Axon reflex (AXR sweat volume was also significantly reduced in AD (normal and eczematous skin and AD/SS (normal and eczema compared to normal control. In contrast, the direct sweat volume of lesional or non-lesional AD skin induced by direct stimulation with acetylcholine was only slightly reduced compared to that in normal controls, but not in SS and lesional skin of AD/SS patients. These results suggest that the impaired sweat response in AD is attributable to an abnormal sudomotor axon reflex, which is accelerated and modulated when complicated by SS resulting in dry skin in the present cases.
Wound healing during the diabetic foot disease is indicated to in-patient treatment in case of non-healing wound, in case of serious infection and/or critical ischemia and in case of necessity of surgical treatment. Diabetic foot disease is the main reason for in-patient treatment of people with diabetes, which our experience confirms. Chronic wound is characterised by non-healing for at least 4 weeks. Ischemia and recurrent trauma caused by incomplete off-loading, prolong inflammation and infection are the main reasons for difficult healing of chronic wound. Infection is also leading cause for prolonged hospitalisation of patients with diabetic foot disease. Local decrease of grow factors and increase of tissue protease are characteristics of chronic wound. The process of wound healing is characterized by a cascade of interrelated events involving infection and inflammatory factors. The results of these investigations led to the moist wound healing concept and use of growth factors and bioengineered skin substitutes. We have good experience with the use of xenotransplant skin substitues in the treatment of diabetic foot. Off loading techniques including total contact casting, local therapy by debridement and skin substitutes had the best evidence based efficacy. We are introducing new method of the treatment of diabetic foot--VAC--vacuum assisted closure. The fundamental principle in the therapy during in-patient period, is comprehensive approach; the omitting of any of the principle of the therapy--e.g. the off-loading of the ulcers, the infection and ischemia control, may contribute to its failure.

Pollen food allergy syndrome (PFAS), also called oral allergy syndrome, is a form of food allergy in which uncooked foods cause allergic symptoms generally limited to the oral mucosa. It occurs in a subset of patients with pollen allergy, although not all patients have prominent rhinitis symptoms. PFAS is related to antigenic similarity between the pollen and food allergen. The size of skin test reactions in a group of subjects with pollen sensitivity with PFAS was compared with a group of subjects who were pollen sensitive and without PFAS. Self-reported rhinitis symptoms between the two groups were compared to identify if symptom severity differed. Twenty subjects with PFAS and 20 subjects with seasonal allergic rhinitis without PFAS were enrolled in the study. All the subjects underwent standard skin-prick testing to a panel of common allergens, including select fresh fruits and vegetables. The subjects completed a Mini Rhinoconjunctivitis Quality of Life Questionnaire as part of their clinical evaluation. The subjects with PFAS and those without PFAS were compared statistically. The subjects with PFAS had significantly larger-sized skin-prick test results specific to pollens (p PFAS reported milder nasal symptoms in relation to pollen skin test result size when compared with allergic rhinitis controls without PFAS. Our study outlined basic differences between two seemingly similar patient groups with a particularly striking discordance between skin test result sizes and rhinitis symptoms. This discordance should be explored further to increase mechanistic understanding of allergen cross-reactivity in PFAS.
Full Text Available A six-month-old girl who presented with dermatitis was found to have multiple, symmetric, deep, gyrate skin folds involving her trunk and similar circumferential lesions on her extremities since birth. She had a characteristic round face with hypertelorism, depressed nasal bridge, thin, down-turned vermillion border of upper lip and short neck. Skin biopsy demonstrated increased smooth muscle fibers in the deeper dermis. A diagnosis of Michelin tire baby syndrome was made. Clinical features, histopathology, differential diagnosis and prognosis of this rare disorder have been discussed.

Full Text Available Venomous animals are those that, by means of a hunting and defense mechanism, are able to inject their prey with a toxic substance produced in their bodies, directly from specialized glands (e.g., tooth, sting, spur through which the poison passes. Millipedes are poisonous animals; they can be harmful to humans, and their effects usually manifest as erythematous, purpuric, and cyanotic lesions; local pain; and paresthesia. Here, we report a case of skin contact with a millipede for 6h resulting in skin lesions similar to blue toe syndrome.

Basal cell carcinoma (BCC) is the most common skin cancer worldwide with increasing incidence, but difficult to assess due to the current under registration practice. Despite the low mortality rate, BCC is a cause of great morbidity and an economic burden to health services. There are several risk factors that increase the risk of BCC and partly explain its incidence. Low-penetrance susceptibility alleles, as well as genetic alterations in signaling pathways, namely SHH pathway, also contribute to the carcinogenesis. BCC associate with several genetic syndromes, of which basal cell nevus syndrome is the most common.
Aberrant distribution patterns of corneodesmosomal components of tape-stripped corneocytes in atopic dermatitis and related skin conditions (ichthyosis vulgaris, Netherton syndrome and peeling skin syndrome type B).

Atopic dermatitis (AD), Netherton syndrome (NS) and peeling skin syndrome type B (PSS) may show some clinical phenotypic overlap. Corneodesmosomes are crucial for maintaining stratum corneum integrity and the components' localization can be visualized by immunostaining tape-stripped corneocytes. In normal skin, they are detected at the cell periphery. To determine whether AD, NS, PSS and ichthyosis vulgaris (IV) have differences in the corneodesmosomal components' distribution and corneocytes surface areas. Corneocytes were tape-stripped from a control group (n=12) and a disease group (37 AD cases, 3 IV cases, 4 NS cases, and 3 PSS cases), and analyzed with immunofluorescent microscopy. The distribution patterns of corneodesmosomal components: desmoglein 1, corneodesmosin, and desmocollin 1 were classified into four types: peripheral, sparse diffuse, dense diffuse and partial diffuse. Corneocyte surface areas were also measured. The corneodesmosome staining patterns were abnormal in the disease group. Other than in the 3 PSS cases, all three components showed similar patterns in each category. In lesional AD skin, the dense diffuse pattern was prominent. A high rate of the partial diffuse pattern, loss of linear cell-cell contacts, and irregular stripping manners were unique to NS. Only in PSS was corneodesmosin staining virtually absent. The corneocyte surface areas correlated significantly with the rate of combined sparse and dense diffuse patterns of desmoglein 1. This method may be used to assess abnormally differentiated corneocytes in AD and other diseases tested. In PSS samples, tape stripping analysis may serve as a non-invasive diagnostic test.

Peeling skin syndrome (PSS) is a rare form of ichthyosis with a probable autosomal recessive inheritance that exhibits superficial, painless, continual, or seasonal cutaneous exfoliation. The syndrome generally appears at birth or in infancy. We report a case of generalized PSS and provide a literature review. A 34-year-old woman reported a lifelong history of generalized and painless peeling of the skin that worsened in summer. Her parents were third degree cousins. Her twin sister and her two cousins presented with the same condition. Physical examination showed widespread superficial sheets of variable size that could be easily removed without bleeding or pain. No underlying erythema was noted. Otherwise, the patient was in good health. Histological findings showed an epidermal cleavage within the stratum corneum. The generalized form of PSS is classified into 3 types, A, B, and C, according to the classification system of Traupe and Mevorah. We have tried to classify the cases of generalized PSS already reported in the literature into one of these three types. Thirteen reported cases probably presented PSS-type A. Sixteen patients are best described as PSS-type B. Two patients exhibit PSS-type C. Fifteen reported patients had an acral form of peeling skin syndrome. The classification of the eleven remaining patients was difficult to determine. Our patient presented clinical and histological features of generalized PSS-type A.
Full Text Available The acral peeling skin syndrome (APSS is a rare autosomal recessive disorder clinically characterized by asymptomatic desquamation of the skin limited to the hands and feet and histologically by cleavage at the stratum granulosum and stratum corneum level [Kiritsi et al.: J Invest Dermatol 2010;130:1741-1746]. We report on a 10-month-old boy with a history of skin peeling limited to the hands and feet since 2 months of age. Clinical examination revealed erythematous erosions with peripheral desquamation and flaccid blisters. DNA mutation analysis detected two heterozygous TGM5 mutations: c.2T>C, p.M1T in exon 1 and c.337G>T, p.G113C in exon 3 in keeping with the diagnosis of APSS. The clinical presentation of APSS alone might be confusing and strongly resemble epidermolysis bullosa simplex making the differential diagnosis difficult.

We describe an 8-year-old girl born to second-degree consanguineous parents with complaints of recurrent episodes of hematuria for 6 months. She had generalized peeling of the skin since birth and recurrent purulent cutaneous infections. The clinical presentation and histopathology of the skin biopsy specimen were consistent with the inflammatory variant of peeling skin syndrome (PSS). She also had a single ventricle with pulmonary stenosis, for which a bidirectional Glenn shunt had been placed. The renal biopsy specimen showed immunoglobulin A (IgA) nephropathy. She responded well to enalapril and steroids, with a decrease in proteinuria. IgA nephropathy has not been previously reported in PSS. Complications such as IgA nephropathy in children with PSS would help to further delineate the diverse clinical presentations and the clinical course of this rare dermatosis. We discuss the mechanisms that could explain this hitherto unreported association. © 2014 Wiley Periodicals, Inc.

A 6-year-old spayed female domestic shorthair cat with a 3-week history of inappetence, weight loss, and hiding was examined. A palpable abdominal fluid wave, dehydration, and a small tear on the left flank were noted during initial examination. When the cat was gently restrained for blood sampling, the skin on the dorsal neck tore, leaving a 15 cm x 7 cm flap of skin. Clinicopathological abnormalities included nonregenerative anaemia, hypoalbuminaemia, increased globulin concentration, and mildly elevated aspartate aminotransferase and alkaline phosphatase activities. Abdominal fluid was viscous and had a total protein of 5.3 g dL(-1) with 316 cells microL(-1), consistent with a modified transudate. Cytology of the abdominal fluid revealed 86% nondegenerate neutrophils, 13% macrophages, and 1% small lymphocytes. Histopathological evaluation and indirect immunohistochemistry confirmed a diagnosis of feline infectious peritonitis, hepatic lipidosis and feline skin fragility syndrome. Feline skin fragility syndrome has not previously been reported in association with feline infectious peritonitis (FIP). Its inclusion as a clinical sign associated with FIP may facilitate a diagnosis.

Burns caused by hot drinks and soups can be both debilitating and costly, especially to pediatric and geriatric patients. This research is aimed at better understanding the fluid properties that can influence the severity of skin burns. We use a standard model which combines heat transfer and biomedical equations to predict burn severity. In particular, experimental data from a physical model serves as the input to our numerical model to determine the severity of scald burns as a consequence of actual fluid flows. This technique enables us to numerically predict the heat transfer from the hot soup into the skin, without the need to numerically estimate the complex fluid mechanics and thermodynamics of the potentially highly viscous and heterogeneous soup. While the temperature of the soup is obviously is the most important fact in determining the degree of burn, we also find that more viscous fluids result in more severe burns, as the slower flowing thicker fluids remain in contact with the skin for longer. Furthermore, other factors can also increase the severity of burn such as a higher initial fluid temperature, a greater fluid thermal conductivity, or a higher thermal capacity of the fluid. Our combined experimental and numerical investigation finds that for average skin properties a very viscous fluid at 100°C, the fluid must be in contact with the skin for around 15-20s to cause second degree burns, and more than 80s to cause a third degree burn.

Chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) syndrome is a newly characterized autoinflammatory disorder, caused by mutations in PSMB8. It is characterized by early-onset fevers, accompanied by a widespread, violaceous and often annular, cutaneous eruption. While the exact pathogenesis of this syndrome is still obscure, it is postulated that the inflammatory disease manifestations stem from excess secretion of interferons. Based on preliminary blood cytokine and gene expression studies, the signature seems to come mostly from type I interferons, which are proposed to lead to the recruitment of immature myeloid cells into the dermis and subcutis. In this study, we systematically analyzed skin biopsies from 6 CANDLE syndrome patients by routine histopathology and immunohistochemistry methods. Skin lesions showed the presence of extensive mixed dermal and subcutaneous inflammatory infiltrate, composed of mononuclear cells, atypical myeloid cells, neutrophils, eosinophils and some mature lymphocytes. Positive LEDER and myeloperoxidase staining supported the presence of myeloid cells. Positive CD68/PMG1 and CD163 staining confirmed the existence of histiocytes and monocytic macrophages in the inflammatory infiltrate. CD123 staining was positive, demonstrating the presence of plasmacytoid dendritic cells. Uncovering the unique histopathologic and immunohistochemical features of CANDLE syndrome provides tools for rapid and specific diagnosis of this disorder as well as further insight into the pathogenesis of this severe, life-threatening condition.

Extracellular adenosine triphosphate (ATP), present in thermally injured tissue, modulates the inflammatory response and causes significant tissue damage. The authors hypothesize that neutrophil infiltration and ensuing tissue necrosis would be mitigated by removing ATP-dependent signaling at the burn site. Mice were subjected to 30% TBSA partial-thickness scald burn by dorsal skin immersion in a water bath at 60 or 20°C (nonburn controls). In the treatment arm, an ATP hydrolyzing enzyme, apyrase, was applied directly to the site immediately after injury. Skin was harvested after 24 hours and 5 days for hematoxylin and eosin stain, elastase, and Ki-67 staining. Tumor necrosis factor (TNF)-α and interferon (IFN)-β expression were measured through quantitative real-time polymerase chain reaction. At 24 hours, the amount of neutrophil infiltration was different between the burn and burn + apyrase groups (P burn group at 24 hours and 5 days. TNF-α and IFN-β expression at 24 hours in the apyrase group was lower than in the burn group (P burn site allays the neutrophil response to thermal injury and reduces tissue necrosis. This decrease in inflammation and tissue necrosis is at least partially because of TNF-α and IFN-β signaling. Apyrase could be used as topical inflammatory regulators to quell the injury caused by inflammation.
Full Text Available An 81-year-old Japanese man presented with dark blue papules and nodules on his face. There were multiple soft papules and nodules, dark blue in color, compressive, and ranging in size from 2 to 10 mm. A few similar lesions were seen on the patient's right dorsal second toe and right buccal mucosa. There were no skin lesions on his trunk and upper limbs. The patient's past history did not include gastrointestinal bleeding or anemia. Histopathological examination showed dilated vascular spaces lined by the normal epithelium extending beneath the dermis and into the subcutaneous fat. Endoscopy of the gastrointestinal tract to check for colon involvement was not performed. X-ray images of the limbs revealed no abnormalities in the bones or joints. Laboratory investigations did not show anemia. Although we failed to confirm a diagnosis by endoscopy, the skin lesions, histopathological findings, lack of abnormal X-ray findings, and the presence of oral lesions as a part of gastrointestinal tract guided the diagnosis of blue rubber bleb nevus syndrome (BRBNS. Skin lesions of BRBNS occur predominantly on the trunk and upper limbs. However, the present case showed multiple skin lesions predominantly on the face. Therefore, it is important for clinicians to know about a possible atypical distribution of skin lesions in BRBNS.

Swine carcasses at slaughter are normally scalded after bleeding, i.e. immersed in a hot-water-tank. The present study was made to investigate whether during this treatment scalding water enters the severed vessels via the stick wound and contaminates the carcass. Five experimental pigs were slaughtered and immersed in a scalding vat containing water with a dispersed radiolabelled colloid, sup(99m)Tc-sulphide. After scalding muscles and other tissues from various parts of the body were examined for radioactivity. Scalding water (radioactivity) could be demonstrated in tissues from all investigated parts of the carcass. The highest amounts were found in the lungs and in the large blood vessels. The hygienic significance of the findings is discussed.

Objective: To study the effects of seawater immersion on the inflammatory response and oxygen free radical injury of rats with superficial-thickness scald at early stage. Methods: Seventy Wistar rats were divided into healthy control group (HC, n =7), pure scald group (PS, n =21), scald+ fresh water immersion group (SF, n =21), and scald+ seawater immersion group (SS, n =21) according to the random number table. Rats in group HC did not receive any treatment, while 5% total body surface area superficial partial-thickness scald was made on the back of rats in the latter three groups. Rats in group PS lived freely immediately post burn, while wounds on the back of rats in groups SF and SS were immersed into fresh water and seawater, respectively. Serum and full-thickness skin tissue in the center of wounds on the back of 7 rats in groups PS, SF, and SS at post immersion (injury) hour (PIH) 2, 4, and 6 were collected, respectively, while serum and full-thickness skin tissue at the same position of the 7 rats in group HC were collected at PIH 6 of rats in other groups. Morphology of skin tissue was observed with HE staining; tumor necrosis factor-alpha (TNF-α) content in serum and skin tissue was determined by enzyme-linked immunosorbent assay; superoxide dismutase (SOD) content in serum and skin tissue was determined by hydroxylamine method; malondialdehyde content in serum and skin tissue was determined by thiobarbituric acid method. Data were processed with analysis of variance of factorial design, one-way analysis of variance, Welch test, LSD test, and Tamhane test. Results: (1) Epidermal cells of skin tissue of rats in group HC arranged in order and continuously, and the dermis tissue and accessory structures were clear and complete. The skin layer and epidermis of wounds of rats in group PS had no significant change, but the edema of epidermis and dermis and infiltration of inflammatory cells enhanced over time at PIH 2, 4, and 6. The horny layer of epidermis of

All had non-inflammatory generalized disease of type-A PSS variety, except one who had type-B PSS. Two Muslim families (1 st and 2 nd family, total 5 patients came from nearby country Bangladesh, and the 2 Hindu families were Indian. Higher severity over acral areas in generalized type, possible autosomal dominant pattern of inheritance and improvement with age as found in this series were new manifestations and possibly unreported previously. The disease was found to be poorly responsive to oral retinoids. Prevalence of the disease may be higher than expected. Importance of mutational analysis was also highlighted.

Peeling skin syndrome (PSS) is a rare recessively inherited ichthyosiform genodermatoses characterized by superficial skin peeling. This has 2 subtypes, acral (APSS; OMIM 609796) and generalized form (OMIM 270300). The later has been subdivided into type A (non-inflammatory) and type B (inflammatory). Eight cases of peeling skin syndrome in 4 families were recorded over a period of 5 years. They were diagnosed clinically and confirmed histopathologically. Disease onset ranged from birth to childhood age (mean 5.25 ± 4.528 years) and age at presentation ranged from 7-35 years (mean 23.25 ± 10.471 years). Males outnumbered females (M:F - 5:3). All had non-inflammatory generalized disease of type-A PSS variety, except one who had type-B PSS. Two Muslim families (1 st and 2 nd family, total 5 patients) came from nearby country Bangladesh, and the 2 Hindu families were Indian.

Joint hypermobility syndrome/Ehlers-Danlos syndrome hypermobility type (JHS/EDS-HT), is likely the most common systemic heritable connective tissue disorder, and is mostly recognized by generalized joint hypermobility, joint instability complications, minor skin changes and a wide range of satellite features. JHS/EDS-HT is considered an autosomal dominant trait but is still without a defined molecular basis. The absence of (a) causative gene(s) for JHS/EDS-HT is likely attributable to marked genetic heterogeneity and/or interaction of multiple loci. In order to help in deciphering such a complex molecular background, we carried out a comprehensive immunofluorescence analysis and gene expression profiling in cultured skin fibroblasts from five women affected with JHS/EDS-HT. Protein study revealed disarray of several matrix structural components such as fibrillins, tenascins, elastin, collagens, fibronectin, and their integrin receptors. Transcriptome analysis indicated perturbation of different signaling cascades that are required for homeostatic regulation either during development or in adult tissues as well as altered expression of several genes involved in maintenance of extracellular matrix architecture and homeostasis (e.g., SPON2, TGM2, MMP16, GPC4, SULF1), cell-cell adhesion (e.g., CDH2, CHD10, PCDH9, CLDN11, FLG, DSP), immune/inflammatory/pain responses (e.g., CFD, AQP9, COLEC12, KCNQ5, PRLR), and essential for redox balance (e.g., ADH1C, AKR1C2, AKR1C3, MAOB, GSTM5). Our findings provide a picture of the gene expression profile and dysregulated pathways in JHS/EDS-HT skin fibroblasts that correlate well with the systemic phenotype of the patients.

Skin fibroblasts from a patient with Bloom's syndrome (86NoKi) were assayed for various DNA repair activities after ultraviolet light (UV) irradiation. Cultured fibroblasts as well as lymphocytes obtained from this patient showed a high frequency of spontaneous sister chromatid exchanges (SCEs). There was no significant difference between 86NoKi fibroblasts and skin fibroblasts from normal donors in the sensitivity to UV as measured by inactivation of colony forming activity, the capacity of host-cell reactivation (HCR) of UV-irradiated virus, and the amount of unscheduled DNA synthesis (UDS) after UV irradiation. However, the yield of UV-induced SCEs in 86NoKi cells was significantly higher than that in normal cells. (author)

In this issue, Israeli and colleagues confirm that homozygous mutations in corneodesmosin (CDSN) cause type B peeling skin syndrome (PSS), an autosomal recessive skin disorder. The deletion mutation described resulted in a frameshift, producing a downstream premature stop codon and early truncation of the protein. The recently described CDSN nonsense mutation in another PSS family also resulted in protein truncation and nonsense-mediated mRNA decay. Type B generalized PSS can now be clearly distinguished from acral PSS, caused by mutations in transglutaminase 5. This directly affects cornified envelope cross-linking rather than corneodesmosome adherence. These observations provide new insight into the molecular defects underlying two closely related forms of PSS.

Acral peeling skin syndrome is a rare autosomal recessive disorder in which skin exfoliation is limited to the hands and feet. While it typically manifests from early childhood, in this first reported case from South Africa, the patient did not manifest clinically until the fourth decade of life. A 44-year-old woman of African descent, 1 of a set of non-identical twins, presented with recurrent episodes of skin peeling of the upper and lower limbs. The first episode occurred 4 years prior, followed by perennial skin peeling during the spring seasons. She was not on treatment for any chronic disease and reported no exposure to chemicals or other irritants. The family, including the non-identical twin sister, has no history of skin disorders and the patient's HIV antibody test was negative. At presentation, physical examination revealed ongoing exfoliation with new skin formation on the palms and soles. The mucous membranes and nails were spared. Other systems were normal. Skin biopsy taken from the palms confirmed peeling skin syndrome. The patient was managed with topical aqueous cream and analgesics. She was briefly counseled on the nature and prognosis of the disease, and referred for genetic testing and counseling. On follow-up, she continues to have skin peeling once or twice a year. This first reported case of this rare disease in South Africa contributes to the growing body of literature on the disease and highlights the need for clinicians to be aware of its variable clinical onset.
Full Text Available The burns intensive care unit (BICU staff observed an increasing number of pediatric scald burn admissions as a result of increase injuries associated with the scald burns. A retrospective study was conducted to identify scalds demographics, etiologies, and mortality risk factors. This descriptive study comprised a total of 166 patients aged 0-5 years, who were admitted to the BICU of the Reconstructive Plastic Surgery and Burns Unit (RPSBU through the Accident and Emergency (A and E Centre of the Komfo Anokye Teaching Hospital (KATH from May 1 st 2009 to April 30 th 2012. Source of information was the BICU Computerized Database System. Data extracted included demographics as well as treatment methods and outcomes. The study population was 166; 92 (55.4% males and 74 (44.6% females. Scalds admissions were 141 (84.9%; 13 (9.2% of them died, 83 (58.9% discharged, and 45 (31.9% transferred-out to another burn ward and pediatric surgery ward in the hospital.

Ehlers-Danlos syndrome (EDS) is the name for a heterogenous group of rare genetic connective tissue disorders with an overall incidence of 1 in 5000. The histological characteristics of EDS have been previously described in detail in the late 1970s and early 1980s. Since that time, the classification of EDS has undergone significant changes, yet the description of the histological features of collagen morphology in different EDS subtypes has endured the test of time. Nonlinear microscopy techniques can be utilized for non-invasive in vivo label-free imaging of the skin. Among these techniques, two-photon absorption fluorescence (TPF) microscopy can visualize endogenous fluorophores, such as elastin, while the morphology of collagen fibers can be assessed by second-harmonic generation (SHG) microscopy. In our present work, we performed TPF and SHG microscopy imaging on ex vivo skin samples of one patient with classical EDS and two patients with vascular EDS and two healthy controls. We detected irregular, loosely dispersed collagen fibers in a non-parallel arrangement in the dermis of the EDS patients, while as expected, there was no noticeable impairment in the elastin content. Based on further studies on a larger number of patients, in vivo nonlinear microscopic imaging could be utilized for the assessment of the skin status of EDS patients in the future.

Acral peeling skin syndrome (APSS) is an autosomal recessive skin disorder characterized by acral blistering and peeling of the outermost layers of the epidermis. It is caused by mutations in the gene for transglutaminase 5, TGM5. Here, we report on clinical and molecular findings in 11 patients and extend the TGM5 mutation database by four, to our knowledge, previously unreported mutations: p.M1T, p.L41P, p.L214CfsX15, and p.S604IfsX9. The recurrent mutation p.G113C was found in 9 patients, but also in 3 of 100 control individuals in a heterozygous state, indicating that APSS might be more widespread than hitherto expected. Using quantitative real-time PCR, immunoblotting, and immunofluorescence analysis, we demonstrate that expression and distribution of several epidermal differentiation markers and corneodesmosin (CDSN) is altered in APSS keratinocytes and skin. Although the expression of transglutaminases 1 and 3 was not changed, we found an upregulation of keratin 1, keratin 10, involucrin, loricrin, and CDSN, probably as compensatory mechanisms for stabilization of the epidermal barrier. Our results give insights into the consequences of TGM5 mutations on terminal epidermal differentiation.

Malignant disease involving the skin represents a significant work load to the general radiotherapist and can involve interesting diagnostic and therapeutic decisions. Primary skin cancer is also relatively common and there is a need to provide an efficient service in which the first treatment is successful in the majority of patients. The reward for careful attention to technique is very considerable both in terms of clinical cancer control and functional results. Squamous cell carcinoma, basal cell carcinoma, and intra-epidermal carcinoma constitute the majority of the lesions dealt with clinically, but metastatic disease, lymphomas, and malignant melanomas are also referred regularly for opinions and may require radiotherapy. The general principle of the techniques of assessment and radiotherapeutic management to be described are equally applicable to any malignant skin tumour once the decision has been made to accept it for radiotherapy. Dosage and fractionation may have to be adjusted to allow for the nature of the disease process and the intent of the treatment

To explore the preventive and treatment effects of smectite powder on enteral bacterial translocation in scalded rats. Fifty-four Sprague-Dawley (SD) rats were randomly divided into three groups, i.e. normal control (A, n = 6), burn control (B, n = 24), and burn treatment (T, n = 24) groups. The rats in B and T groups were fed with tracing bacteria JM109, which was transfected with PUC19 plasmid in advance. The rats were subjected to 30% TBSA scald injury after the plasmid was shown to have colonized in the intestine. Smectite powder (0.6 g/day/kg) was fed to rats of T group immediately after the scalding, while those in B group received no smectite powder. Bacterial translocation in blood and mesenteric lymph nodes in all groups was observed and identified by enzyme digestion at 12 post scald hour (PSH) and on 1, 3 and 5 post-scald days (PSD). The contents of malondialdehyde (MDA) and superoxide dismutase (SOD) were determined in rat intestinal tissue. And the degree of injury to the entire small intestine was observed pathologically. The villus height of intestinal mucosa was measured, and the rate of epithelial nuclear splitting of mucosal crypts was calculated. The number of rats with positive blood bacterial culture in B group was obviously higher than that in A and T groups (P Smectite powder is beneficial to the protection of the intestinal mucosa in scalded rats, and can effectively prevent postburn intestinal bacterial translocation in rats.

Infectious diseases of wildlife are increasing worldwide with implications for conservation and human public health. The microbiota (i.e. microbial community living on or in a host) could influence wildlife disease resistance or tolerance. White-nose syndrome (WNS), caused by the fungus Pseudogymnoascus destructans (Pd), has killed millions of hibernating North American bats since 2007. We characterized the skin microbiota of naïve, pre-WNS little brown bats (Myotis lucifugus) from three WNS-negative hibernation sites and persisting, previously exposed bats from three WNS-positive sites to test the hypothesis that the skin microbiota of bats shifts following WNS invasion. Using high-throughput 16S rRNA gene sequencing on 66 bats and 11 environmental samples, we found that hibernation site strongly influenced the composition and diversity of the skin microbiota. Bats from WNS-positive and WNS-negative sites differed in alpha and beta diversity, as well as in microbiota composition. Alpha diversity was reduced in persisting, WNS-positive bats, and the microbiota profile was enriched with particular taxa such Janthinobacterium, Micrococcaceae, Pseudomonas, Ralstonia, and Rhodococcus. Some of these taxa are recognized for their antifungal activity, and specific strains of Rhodococcus and Pseudomonas are known to inhibit Pd growth. Composition of the microbial community in the hibernaculum environment and the community on bat skin was superficially similar but differed in relative abundance of some bacterial taxa. Our results are consistent with the hypothesis that Pd invasion leads to a shift in the skin microbiota of surviving bats and suggest the possibility that the microbiota plays a protective role for bats facing WNS. The detection of what appears to be enrichment of beneficial bacteria in the skin microbiota of persisting bats is a promising discovery for species re-establishment. Our findings highlight not only the potential value of management actions that

Background The tumor spectrum in the Lynch syndrome is well defined, comprising an increased risk of developing colonic and extracolonic malignancies. Muir-Torre syndrome is a variant with a higher risk of skin disease. Patients have been described carrying mutations in the mismatch repair genes and presenting tumors with unusual histology or affected organ not part of the Lynch syndrome spectrum. Hence, the real link between Lynch syndrome, or Muir-Torre syndrome, and these tumors remains di...

The term Michelin tire baby (MTB), named for the cartoon mascot of the Michelin Tire Company, has been used to describe babies with multiple symmetric circumferential rings of folded skin. In those reported with this phenotype who had skin biopsies, pathology has shown nevus lipomatosis, smooth muscle hamartoma, degenerative collagen, and scarring. Others did not undergo biopsy or had normal skin. Many individuals with the MTB phenotype have had a variety of other congenital anomalies. I review the literature on MTB and the history of the designation Michelin tire baby Syndrome (MTBS). Because the term MTBS has been poorly defined or not defined at all, I propose strict criteria for diagnosis. In doing so, it is recommended that the syndrome be renamed to avoid further confusion. © 2014 Wiley Periodicals, Inc.
The Gardner-Diamond Syndrome is an infrequently diagnosed impressive psychosomatosis. The patients (exclusively female) suffering from this disorder are described as "angry young women". They are considered hysterical, masochistic, depressive, hostile and timid. Physically the syndrome is characterized by atypical, painful, apparently spontaneous skin bleeding in young women and these patients look like they have been beaten, injured or are seriously ill. Besides hematoma, renal hemorrhage, uterine hemorrhage, headaches or unconsciousness as well as numerous symptoms of conversion in the narrower sense of the word have been observed, e.g. loss speech, gait deviation, or feelings of discomfort. To this day the pathophysiological peculiarity that enables the patients to transform subconscious psychic events into the specific temporary alteration in the permeability of the capillary walls being a constitutional variant characteristic of females suffering from Gardner-Diamond Syndrome and activated by psychic stimuli. In the case history presented, the problem is the psychic working out of narcissistic injuries in the context of a borderline structure. These injuries turn into physical symptoms analogous to the process of conversion. Since, in this case, there is no question of a defense against oedipal fantasies one would prefer to speak of a "narcissistic conversion". Quite peculiar is the universally described resemblance of the patients to one another. The syndrome, together with the character and psychodynamic features, is repeated in almost a stereotypical manner. An explanation for this phenomenon cannot be expected even from the discovery of a pathophysiological detail in the blood vessels. Rather, we are confronted with one of those extremely rare syndromes where, in a limited field, physical and psychic events are completely blended. The physical events such as affects and defense mechanisms for which they can be substituted at random and without mutual
Full Text Available Severe burn injuries may result in gastrointestinal paralysis, and barrier dysfunction due to gut ischemia and lowered vagus excitability. In this study we investigate whether electroacupuncture (EA at Zusanli (ST36 could prevent severe scalds-induced gut ischemia, paralysis, and barrier dysfunction and whether the protective role of EA at ST36 is related to the vagus nerve. 35% burn area rats were divided into six groups: (a EAN: EA nonchannel acupoints followed by scald injury; (b EA: EA at ST36 after scald injury; (c VGX/EA: vagotomy (VGX before EA at ST36 and scald injury; (d VGX/EAN: VGX before EAN and scald injury; (e atropine/EA: applying atropine before scald injury and then EA at ST36; (f atropine/EAN: applying atropine before scald injury and then EA at nonchannel acupoints. EA at the Zusanli point significantly promoted the intestinal impelling ratio and increased the amount of mucosal blood flow after scald injury. The plasma diamine oxidase (DAO and intestinal permeability decreased significantly after scald injury in the EA group compared with others. However, EA after atropine injection or cervical vagotomy failed to improve intestinal motility and mucosa blood flow suggesting that the mechanism of EA may be related to the activation of the cholinergic nerve pathway.

Full Text Available Objective. To detect anticardiolipin antibodies (АСА, anti-p2-GPl antibodies, C3 and C4 complement components in immune complexes including those containing АСА in skin and muscle eluates of pts with systemic lupus erythematosus (SLE and antiphospholipid syndrome (APS. Material and methods . In 7 pts (6 female and I male, 2 with primary APS, 3 with SLE+APS and 2 with SLE skin and muscle biopsies were taken. 6 from 7 pts had thrombotic complications. Eluates were obtained from frozen skin and skeletal muscle biopsies (size was 1,5x0,5 and 0,5x0,5 respectively. Because of small size of biopsies it was not possible to use traditional methods of tissue pounding such as sharp homogenization of tissues in homogenizers with pulverizing and subsequent process of freezing-unfreezing which lead to large protein loss and make impossible serological tissue analysis. Application of acid eluates method by T.E.W. Feltkamp and J,H. Boode of own modification allowed to minimize tissue protein loss and perform serological tissue analysis. Results. Serum of all 7 pts contained antiphospholipid antibodies - IgG-ACA in 3, combination of IgG- und IgM-ACA in 5. In 5 from 7 eluates lgG АСА exceeded 0,109 OO units were revealed. They contained СЗ, C4 and different protein products mostly immunoglobulines. Anti-(I2GP1 antiboddie;. were absent. Conclusion. For the first time presence of АСА in tissues of APS pts was showed which may be of particular interest in studying morphogenesis of local tissue disturbances with participation of immune complexes containing АСА.

Acral peeling skin syndrome (APSS) is a rare skin fragility disorder usually caused by mutations in the transglutaminase 5 gene (TGM5). We investigated the mutation spectrum of APSS in the U.K., Germany and Poland. We identified 59 children with APSS from 52 families. The phenotype was readily recognizable, with some variation in severity both within and between families. Most cases had been misdiagnosed as the localized form of epidermolysis bullosa simplex (EBS-loc). Eighteen different TGM5 mutations were identified, 15 of which were novel. Eight mutations were unique to a single family, nine each occurred in two families, while the common p.Gly113Cys mutation linked to a second missense variant p.Thr109Met occurred in 47 of the 52 families and was homozygous in 28. Most patients were of nonconsanguineous white European origin. We propose that APSS is under-reported and widely misdiagnosed as EBS-loc, with significant counselling implications as APSS is autosomal recessive while EBS-loc is dominant. We recommend screening for TGM5 mutations when EBS-loc is suspected but not confirmed by mutations in KRT5 or KRT14. Our report trebles the number of known TGM5 mutations. It provides further evidence that p.Gly113Cys is a founder mutation in the European population. This is consistent with the striking ethnic distribution of APSS in U.K., where the majority of patients are of nonconsanguineous white European origin, in contrast to the pattern of other recessive skin disorders. © 2014 British Association of Dermatologists.

In response to two isolated cases of Mycobacterium chelonae infections in tattoo recipients where tap water was used to dilute ink, the New York City (NYC) Department of Health and Mental Hygiene conducted an investigation using Emergency Department (ED) syndromic surveillance to assess whether an outbreak was occuring. ED visits with chief complaints containing the key word "tattoo" from November 1, 2012 to March 18, 2013 were selected for study. NYC laboratories were also contacted and asked to report skin or soft tissue cultures in tattoo recipients that were positive for non-tuberculosis mycobacterial infection (NTM). Thirty-one TREDV were identified and 14 (45%) were interviewed to determine if a NTM was the cause for the visit. One ED visit met the case definition and was referred to a dermatologist. This individual was negative for NTM. No tattoo-associated NTM cases were reported by NYC laboratories. ED syndromic surveillance was utilized to investigate a non-reportable condition for which no other data source existed. The results were reassuring that an outbreak of NTM in tattoo recipients was not occurring. In response to concerns about potential NTM infections, the department sent a letter to all licensed tattoo artists advising them not to dilute tattoo ink with tap water.

White-nose syndrome (WNS) has claimed the lives of millions of hibernating insectivorous bats in North America. Its etiologic agent, the psychrophilic fungus Geomyces destructans, causes skin lesions that are the hallmark of the disease.

Full Text Available Background. Hyper IgE is a rare systemic disease characterized by the clinical triad of high serum levels of IgE (>2000 IU/mL, eczema, and recurrent staphylococcal skin and lung infections. The presentation of hyper IgE syndrome is highly variable, which makes it easy to confuse the diagnosis with that of severe atopy or other rare immunodeficiency disorders. Case Report. A 23-year-old Hispanic presented with history of frequent respiratory and gastrointestinal infections as a child and multiple episodes of skin and lung infections (abscess with Staphylococcus aureus throughout his adult life. He had multiple eczematous lesions and folliculitis over his entire body, oral/esophageal candidiasis, and retention of his primary teeth. The IgE was elevated (>5000 IU/mL. Genetic mutation analysis revealed a mutation affecting the transactivation domain of the STAT3 gene. Conclusion. The hallmark of hyper IgE syndrome is serum IgE of >2000 IU/mL. Hyper IgE syndrome is a genetic disorder that is either autosomal dominant or recessive. A definite diagnosis can be made with genetic mutation analysis, and in this case, it revealed a very rare finding of the transactivation domain STAT3 mutation. Hyper IgE syndrome is a challenge for clinicians in establishing a diagnosis in suspected cases.

The most common pediatric burn injury is a superficial scald. The current follow-up protocol for such burns includes review of the patient at 2 weeks postinjury and then 2 months later. The authors decided to review the protocol to assess the need for this second follow-up. A retrospective study reviewed the case notes of patients younger than 16 years at the time of their injury presenting with a scald over 5% TBSA. The progress of healing and scar development up to 5 years follow-up was assessed. This study showed that scalds healing within 2 weeks following injury rarely became hypertrophic. A prospective study was performed over a 10-month period. All children who suffered a superficial partial-thickness scald injury were included. At the 2-week appointment, the need for further follow-up was predicted. The accuracy of this prediction was assessed 2 months later. This study showed that an experienced member of the burns team could reliably predict at 2-week appointment those children who could be safely discharged with no subsequent need for scar management. This study suggests that it will be safe to modify the follow-up protocol, reducing the number of clinic attendances.

Introduction POEMS syndrome (an acronym of polyneuropathy, organomegaly, endocrinopathy, multiple myeloma and skin changes) is a paraneoplastic disorder related to an underlying plasma cell dyscrasia. The development of such a syndrome is rare and its association with calvarial plasmocytoma is even less common, with only two previous reported cases. We describe, in detail, an unusual presentation of cranial plasmocytoma associated with POEMS syndrome and briefly discuss the possible role of s...
Full Text Available To investigate whether pigmentation genes involved in the melanogenic pathway (melanogenesis contributed to melanoma predisposition, we compared pigmentary genetics with quantitative skin pigmentation measurements, the number of atypical nevi, the total nevus count, and the familial atypical multiple mole and melanoma (FAMMM syndrome. We typed 32 pigmentary SNP markers and sequenced MC1R in 246 healthy individuals and 116 individuals attending periodic control for malignant melanoma development, 50 of which were diagnosed with FAMMM. It was observed that individuals with any two grouped MC1R variants (missense, NM_002386:c. 456C > A (p.TYR152*, or NM_002386:c.83_84insA (p.Asn29Glnfs*14 had significantly (p<0.001 lighter skin pigmentation of the upper-inner arm than those with none or one MC1R variant. We did not observe any significant association of the MC1R variants with constitutive pigmentation measured on the buttock area. We hypothesize that the effect of MC1R variants on arm pigmentation is primarily reflecting the inability to tan when subjected to UVR. A gender specific effect on skin pigmentation was also observed, and it was found that the skin pigmentation of females on average were darker than that of males (p<0.01. We conclude that MC1R variants are associated with quantitative skin colour in a lightly pigmented Danish population. We did not observe any association between any pigmentary marker and the FAMMM syndrome. We suggest that the genetics of FAMMM is not related to the genetics of the pigmentary pathway.

Limited data is available for treatment of scald lesions in adults. The use of the biosynthetic matrix Biobrane ® has been suggested as treatment option with more benefits over topical dressings. Application of Biobrane ® in scalds in our center led to a perceived increase of infection, secondary deepening, surgery and length of stay. We therefore assessed the effect of different treatment options in adult scalds in our center. We performed a retrospective cohort study of adult patients that have been admitted with scalds in our center between 2011 and 2014. We assessed two groups, group 1 with Biobrane ® as initial treatment and group 2 with topical treatment using polyhexanid hydrogel and fatty gauze. Primary outcome variables were rate of secondary deepening, surgery, infection (defined as positive microbiological swabs and antibiotic treatment) and length of stay. Total body surface area (TBSA) as well as diabetes mellitus (DM), hypertension, smoking and alcohol consumption as potential confounders were included. A total of 52 patients were included in this study. 36 patients received treatment with Biobrane ® and 16 with ointment and fatty gauze. No significant differences were found for age and TBSA whereas gender ratio was different (25/11 male/female in group 1 vs 4/12 in group 2, p=0.003). Rate of secondary deepening, surgery, infection as well as days of hospital stay (DOHS) were comparable. Logistic and multilinear regression showed TBSA to be a predictive factor for infection (p=0.041), and TBSA and age for length of stay (age p=0.036; TBSA p=0.042) in group 1. The use of Biobrane ® in adult scald lesions is safe and non-inferior to topical treatment options. In elder patients and larger TBSA Biobrane ® may increase the risk of infection or a prolonged stay in hospital. Level 3 - retrospective cohort study. Copyright © 2016 Elsevier Ltd and ISBI.

The Siamese fighting fish (Betta splendens) is one of the popular aquarium ornamental fish in the global trade. Large numbers of ornamental fish farmed in central Thailand suffered from two common syndromes; preliminarily named skin nodule syndrome (SNS) and big belly syndrome (BBS): they showed noticeable clinical signs of abnormal appearances resulting in depressed saleability. Since very few specifics are known about causative agents of these syndromes, this study aimed at investigating histopathological features and culturable bacteria associated with these fish infected in the process of farming. Histopathologically, SNS fish consistently exhibited necrosis and severe melanization in the muscles and multiple internal organs. Whereas BBS fish exhibited either typical granulomas or tissue damage associated with acid-fast stained bacteria and Gram negative bacteria, respectively. Six different Gram negative bacterial species were recovered from BBS fish while 23 bacterial species belonging to 14 genera were recovered from fish suffering from SNS. Most of the culturable bacteria are new to betta fish and some of them are known to be marine bacteria, suggesting possible entry route via a contaminated live feed, commercial Artemia shrimp. The true causative agents of these syndromes remain unclear. However, histopathological changes and existence of a wide range of bacteria associated with the naturally diseased fish suggest involvement of multiple bacterial infections.

Full Text Available Toxic epidermal necrolysis (TEN and Stevens Johnson Syndrome (SJS are severe adverse cutaneous drug reactions that predominantly involve the skin and mucous membranes. They are characterized by mucocutaneous tenderness and typically hemorrhagic erosions, erythema and more or less severe epidermal detachment presenting as blisters and areas of denuded skin. Drugs are assumed or identified as the main cause of SJS/TEN in most cases, but Mycoplasma pneumoniae and Herpes simplex virus infections are well documented causes alongside rare cases in which the etiology remains unknown. Several drugs are at "high" risk of inducing TEN/SJS including: Allopurinol, Trimethoprim-sulfamethoxazole and other sulfonamide-antibiotics, aminopenicillins, cephalosporins, quinolones, carbamazepine, phenytoin, phenobarbital and NSAID's of the oxicam-type. Differential diagnosis includes linear IgA dermatosis and paraneoplastic pemphigus, pemphigus vulgaris and bullous pemphigoid, acute generalized exanthematous pustulosis (AGEP, disseminated fixed bullous drug eruption and staphyloccocal scalded skin syndrome (SSSS. Due to the high risk of mortality, management of patients with SJS/TEN requires rapid diagnosis, identification and interruption of the culprit drug, specialized supportive care ideally in an intensive care unit, and consideration of immunomodulating agents such as high-dose intravenous immunoglobulin therapy.

A heterogeneous response to X-ray and far UV (254 nm) light irradiations was found in cultured skin fibroblast lines from 2 separate families with Gardner's syndrome. When compared to 2 normal control cultures and cultures from 2 patients with nonfamilial colon cancer, cultures from 4 clinically affected members of family 1 showed increased sensitivity to the lethal effects of both X-ray and UV light irradiations. These cells also showed a delayed pattern of X-ray potentially lethal damage repair (PLDR) and absent UV PLDR. In contrast, cultures from 3 members of family 2 (2 of whom were clinically affected) showed a normal response of survival and PLDR to both X-ray and UV light irradiations. Thus increased sensitivity of cultured skin fibroblasts to X-ray and UV light irradiations was not a consistent in vitro finding in patients with Gardner's syndrome. However, in families with Gardner's syndrome who demonstrate in vitro radiosensitivity, additional studies are needed to assess the usefulness of these techniques in detecting affected individuals prior to the development of colon carcinoma and other manifestations

Before the discovery of white-nose syndrome (WNS), a fungal disease caused by Pseudogymnoascus destructans, there were no reports of fungal skin infections in bats during hibernation. In 2011, bats with grossly visible fungal skin infections similar in appearance to WNS were reported from multiple sites in Wisconsin, USA, a state outside the known range of P. destructans and WNS at that time. Tape impressions or swab samples were collected from affected areas of skin from bats with these fungal infections in 2012 and analyzed by microscopy, culture, or direct DNA amplification and sequencing of the fungal internal transcribed spacer region (ITS). A psychrophilic species ofTrichophyton was isolated in culture, detected by direct DNA amplification and sequencing, and observed on tape impressions. Deoxyribonucleic acid indicative of the same fungus was also detected on three of five bat carcasses collected in 2011 and 2012 from Wisconsin, Indiana, and Texas, USA. Superficial fungal skin infections caused by Trichophyton sp. were observed in histopathology for all three bats. Sequencing of the ITS of Trichophyton sp., along with its inability to grow at 25 C, indicated that it represented a previously unknown species, described herein as Trichophyton redellii sp. nov. Genetic diversity present within T. redellii suggests it is native to North America but that it had been overlooked before enhanced efforts to study fungi associated with bats in response to the emergence of WNS.

Acral peeling skin syndrome (APSS) is a clinically and genetically heterogeneous disorder. We used whole-exome sequencing to identify the molecular basis of APSS in a consanguineous Jordanian-American pedigree. We identified a homozygous nonsense mutation (p.Lys22X) in the CSTA gene, encoding cystatin A, that was confirmed using Sanger sequencing. Cystatin A is a protease inhibitor found in the cornified cell envelope, and loss-of-function mutations have previously been reported in two cases of exfoliative ichthyosis. Our study expands the molecular pathology of APSS and demonstrates the value of next-generation sequencing in the genetic characterization of inherited skin diseases. © 2013 Wiley Periodicals, Inc.

Stevens-Johnson syndrome and toxic epidermal necrolysis are severe, life-threatening drug reactions involving skin and membranes mucous, which are associated with significant morbidity and mortality and triggered, especially by drug exposure. Different studies have demonstrated that drug response is a multifactorial character and that the interindividual variability in this response depends on both environmental and genetic factors. The last ones have a relevant significance. In fact, the identification of new specific genetic markers involved in the response to drugs, will be of great utility to establish a more personalized therapeutic approach and to prevent the appearance of these adverse reactions. In this review, we summarize recent progresses in the Pharmacogenetics studies related to Stevens-Johnson syndrome/toxic epidermal necrolysis reporting the major genetic factors identified in the last years as associated with the disease and highlighting the use of some of these genomic variants in the clinical practice.

Burns and scalds are preventable injuries in children that typically occur in the home. This study aimed to examine the role of hot beverage scalds in paediatric burn admissions in order to identify key target audiences for future safety strategies. Using the Hospital Inpatient Enquiry System (HIPE) a retrospective study of paediatric burn admissions in 2014 examined demographics, cause and severity of injury and location of occurrence. There were 233 paediatric discharges (age 0-18 yrs.) with a principal diagnosis of burn injury; 57% of these occurred in children under three years and 95% of these occurred in the home. Scalds caused 74% of burn injuries; hot beverages accounted for least 33% of these of which 77% were partial thickness and 73% were upper body burns. Effective hot beverage scald prevention strategies, targeted towards caregivers in the home, are required.

Linear nonblanching skin lesions are thought to occur very rarely in patients with Henoch-Schönlein syndrome. To examine the prevalence and characteristics of linear nonblanching skin lesions in children with Henoch-Schönlein syndrome. A prospective case series was conducted at the ambulatory practice of a hospitalist between January 1, 2010, and December 31, 2015, among 31 consecutive children with Henoch-Schönlein syndrome. Thirty-one consecutive children affected with Henoch-Schönlein syndrome who were from 3.0 to 12.0 years of age (median age, 6.2 years). Children with Henoch-Schönlein syndrome underwent a careful, structured skin examination established in advance with emphasis on the presence of palpable lesions with a linear pattern. Among the 31 children in the study (12 girls and 19 boys; median age, 6.2 years [range, 3.0-12.0 years]), 8 (26%) had linear lesions on the legs, groin, waistline, wrists, or forearms. Patients with or without linear lesions did not differ significantly with respect to sex, age, and cutaneous, abdominal, articular, or renal involvement. This study illustrates the prevalence and characteristics of linear skin lesions in patients with Henoch-Schönlein syndrome. Patients with symptoms suggestive of this vasculitis should be evaluated for the presence of nonblanching, palpable lesions with a linear pattern.

Hot beverage scalds are a leading cause of burns in young children. The aim of this study was to look at the circumstances surrounding these injuries in terms of setting, mechanism, supervision and first aid to inform a prevention campaign. A cross-sectional study was delivered via iPad to parents and caregivers presenting with a child aged 0-36 months with a hot beverage scald at a major paediatric burns centre. Of the 101 children aged 0-36 months that presented with a hot beverage scald over a 12-month period, 54 participants were included. The scald aetiology was as expected with the peak prevalence in children aged 6-24 months, pulling a cup of hot liquid down over themselves. The majority of injuries occurred in the child's home and were witnessed by the caregiver or parent. The supervising adult was often in close proximity when the scald occurred. Less than a third (28%) of participants received recommended first aid treatment at the scene, with an additional 18% receiving this treatment with three hours of the injury-usually at an emergency department. While the aetiology of these scalds were as expected, the low use of recommended burn first aid was of concern. Although supervision was present in almost all cases, with the parent/caregiver close-by, this proximity still permitted injury. Attentiveness and continuity of supervision, which can be difficult with competing parental demands, appear to play a more important role role; as do considerations of other safety mechanisms such as hazard reduction through keeping hot drinks out of reach and engineering factors such as improved cup design. By incorporating the findings from this study and other research into a hot beverage scald prevention campaign, we hope to see a change in knowledge and behaviour in parents and caregivers of young children, and ultimately a reduction in the incidence of hot beverage scalds.

The metabolic syndrome (MS) has a high prevalence in different parts of the world, with variations between different ethnic groups. This study aims at exploring the influence of the self-reported skin color on the prevalence of MS Methods: Cross-sectional study, carried out in a population subgroup (n=1,439 adults) in Salvador, Brazil. The self-reported skin color (white, mulatto or black) was used as well as the MS criterion of ATP-III. The Chi-square test for tendency was used to analyze the prevalence gradient between the groups and logistic regression, for association analysis. The general prevalence of MS, adjusted for potentially confounder variables, did not differ among whites (23.3%), mulattos (23.3%) and blacks (23.4%). The analysis by sex showed, among men, a reduction in the MS prevalence of whites (26.2%, 95%CI: 20.7-31.7), in comparison to blacks (17.5%, 95%CI: 12.3-22.8) and an intermediate prevalence among mulattos, 21.9%, 95%CI: 18.6-25.1, p tend. = 0.002. Among the women, the tendency was the opposite, being higher among the blacks, 27.0%, 95%CI: 22.2-31.8, and lower among the whites, 20.5%, 95%CI: 15.6-25.4, p tend. = 0.02. The multivariate analysis of the association between skin color and MS (white = group of reference) showed that the black color of the skin was a protective factor among black men, with a prevalence ratio (PR) = 0.60 (0.36-0.97), whereas it tended to be a risk factor among black women, with a PR = 1.33 (0.94-1.78). The prevalence of MA presented an inverse variation according to the color of skin between men and women. To be black was a protective factor among men and a risk factor among women.

Objective: To investigate the significance of plasma CGRP and NPY levels changes immediately after scald in rats. Methods: Thirty-two rat models of 30% TBSA III degree scald were prepared. Eight animals each were sacrificed at 3, 6,12 and 24 hrs; taking blood samples for determination of plasma CGRP, NPY levels and 5 cm of ileum for pathologic study. As controls, eight animals without scald were treated in the same way. Results: Plasma CGRP levels were decreased significantly after scald, reaching bottom value at 12 hr and remained lower than those in controls at 24 hr (p 0.05). Plasma levels of CGRP were negatively correlated to plasma NPY levels (p<0.01). Ileum mucosal injuries presented as edema, congestion with necrosis and slough of epithelium were most marked at 12 hr. Conclusion: Plasma CGRP and NPY levels changed significantly after scald and were mutually negatively correlated. Post-scald intestinal mucosa barrier injuries were possibly related to the changes of levels of those vasoactive peptides

McCune-Albright syndrome is a rare sporadic disease characterized by bone fibrous dysplasia, café-au-lait skin spots and a variable association of hyperfunctional endocrine disorders. Fibrous dysplasia (FD), which can involve the craniofacial, axial, and appendicular skeleton, may range from an isolated, asymptomatic monostotic lesion to a severe disabling polyostotic disease involving the entire skeleton. A twenty-five-year old male patient presented to our clinic with recently developed heart palpitations. He had also been feeling pain in the right femur since he was younger, without any trauma history, leading to difficulties of ambulation and limping occasionally. His physical examination revealed café-au-lait spots with irregular borders and right testicular agenesis. Laboratory findings identified hyperthyroidism with hyperparathyroidism. Radiographs of the pelvis revealed multiple lytic lesions of the right femur and magnetic resonance imaging (MRI) characterized these lesions as specific to fibrous dysplasia of the bone, without any insufficiency fracture at this level. The association of café-au-lait skin spots with bone fibrous dysplasia, and hyperthyroidism in this patient suggested the diagnosis of McCune - Albright syndrome.

Peeling skin disease (PSD), a generalized inflammatory form of peeling skin syndrome, is caused by autosomal recessive nonsense mutations in the corneodesmosin gene (CDSN). To investigate a novel mutation in CDSN. A 50-year-old white woman showed widespread peeling with erythema and elevated serum IgE. DNA sequencing, immunohistochemistry, Western blot and real-time polymerase chain reaction analyses of skin biopsies were performed in order to study the genetics and to characterize the molecular profile of the disease. Histology showed hyperkeratosis and acanthosis of the epidermis, and inflammatory infiltrates in the dermis. DNA sequencing revealed a homozygous mutation leading to a premature termination codon in CDSN: p.Gly142*. Protein analyses showed reduced expression of a 16-kDa corneodesmosin mutant in the upper epidermal layers, whereas the full-length protein was absent. These results are interesting regarding the genotype-phenotype correlations in diseases caused by CDSN mutations. The PSD-causing CDSN mutations identified heretofore result in total corneodesmosin loss, suggesting that PSD is due to full corneodesmosin deficiency. Here, we show for the first time that a mutant corneodesmosin can be stably expressed in some patients with PSD, and that this truncated protein is very probably nonfunctional. © 2013 British Association of Dermatologists.

The metabolic syndrome is a complex construct with interrelated factors of obesity, blood pressure, lipids, and glucose. It is a risk factor for a number of chronic diseases in late life. This study tested a model in which the relationship between stress and the metabolic syndrome was mediated by appraisal, coping, and affect. Data were collected from 518 male participants in the Normative Aging Study (X(age) = 68.17 years). The model was partially confirmed. Relationships among stress, appraisal, coping, and affect were valenced along positive and negative pathways. However, affect was not directly related to the metabolic syndrome. The metabolic syndrome was related to positive coping as operationalized by self-regulatory strategies. The results of this study suggest that the influence of coping on physical health may occur through emotional regulation.

Background Steam inhalation therapy is often recommended in the treatment of a common cold. However, it has no proven benefit and may in fact have serious adverse side effects in terms of burn injuries. Aim To quantify the human and economic costs of steam inhalation therapy in terms of burn injury. Design and setting A prospective database study of all patients admitted to the burn centres (Beverwijk, Groningen, Rotterdam) and the hospital emergency departments in the Netherlands. Method Number and extent of burn injuries as a result of steam inhalation therapy were analysed, as well as an approximation made of the direct costs for their medical treatment. Results Annually, on average three people are admitted to in one of the Dutch burn centres for burns resulting from steam inhalation therapy. Most victims were children, and they needed skin grafting more often than adults. The total direct medical costs for burn centre and emergency department treatment were €115 500 (£93 000), emotional costs are not reflected. Conclusion As steam inhalation therapy has no proven benefit and the number and extent of complications of this therapy in terms of burn injury are significant, especially in children, steam inhalation therapy should be considered a dangerous procedure and not recommended anymore in professional guidelines and patient brochures.

Colonic polyposis and carcinoma developed in a woman with Turcot's syndrome at the age of 31 years; astrocytoma developed when she was 37. Her brother and sister had died of astrocytoma at the ages of 18 and 33 years, respectively. Progressive neutropenia developed in the patient three months after radiotherapy for her brain tumor and acute myelomonocytic leukemia 19 months after treatment. Three laboratories independently evaluated cultures of her skin fibroblasts for in vitro sensitivity to cell killing (loss of colony-forming ability) by x-rays. Survival assays consistently revealed slight but significant radiosensitivity in an early-passage (six to 10 doublings) fibroblast subculture. A later subculture (21 to 29 doublings) showed no abnormality, a possible effect of selective in vitro loss of radiosensitive cells

Cupping therapy has a long history in traditional medicine especially in Asian countries. It was controversial whether cupping induced blisters are beneficial to healing effects, and the formation and content in the blisters remain unexplored. We aimed to identify and compare the molecular components of the blister fluid from the cupping therapy and the scalds to explore the necessary of inducing cupping induced blisters. Fluid sample of blisters from fifteen patients receiving cupping therapy (Cupping group) and scald burns (Scald group) were collected in this study. Proteins from the blisters were separated by two-dimensional electrophoresis (2D-gel) and further analyzed by mass spectrometry. In addition, the changes in particular proteins were confirmed by Western blotting. The protein components are significantly different between blister from cupping therapy and scalds. The immune responses, oxidative stress and metabolic related proteins (Ig lambda-2 chain C regions, Ig gamma-1 chain C region, hemopexin, prdx2, calmodulin, succinyl-CoA ligase and tetranectin) were increased, whereas the hemoglobin subunit beta was decreased in the Cupping group compared with the Scald group. Cupping induced blisters contain several proteins which relate to the activation of certain immune pathways including anti-oxidation, anti-apoptosis, tissue repairing and metabolic regulation. This proteomic analysis may indicate a significant clue to the mechanism study of cupping. Copyright © 2017 Elsevier Ltd. All rights reserved.

Full Text Available Background: Polycystic ovarian syndrome (PCOS is a heterogenous collection of signs and symptoms that when gathered, form a spectrum of disorder with disturbance of reproductive, endocrine and metabolic functions. Aim: The aim of this study is to correlate the skin manifestations with hormonal changes and to know the incidence and prevalence of skin manifestations in patients with PCOS. Materials and Methods: A total of 40 patients with PCOS were examined during 1 year time period from May 2008 P to May 2009. Detailed clinical history was taken from each patient. PCOS was diagnosed on the basis of ultrasonography. Hormonal assays included fasting blood sugar, postprandial blood sugar, follicle-stimulating hormone, luteinizing hormone, thyroid stimulating hormone, dehydroepiandrostenedione, prolactin, free testosterone, fasting lipid profile and sex hormone binding globulin. The results obtained were statistically correlated. Results: In our study, the prevalence of cutaneous manifestations was 90%. Of all the cutaneous manifestations acne was seen in highest percentage (67.5%, followed by hirsutism (62.5%, seborrhea (52.5%, androgenetic alopecia (AGA (30%, acanthosis nigricans (22.5% and acrochordons (10%. Fasting insulin levels was the most common hormonal abnormality seen in both acne and hirsutism, whereas AGA was associated with high testosterone levels. Conclusion: The prevalence of cutaneous manifestations in PCOS was 90%. Hirsutism, acne, seborrhea, acanthosis nigricans and acrochordons were associated with increased levels of fasting insulin, whereas AGA showed higher levels of serum testosterone.

There is limited data regarding pollen food allergy syndrome (PFAS) in Turkey. To investigate the clinical characteristics and possible risk factors of PFAS in Turkey, and to evaluate if there was an association between skin test reactivity to pollens and presence of PFAS. A total of 254 consecutive adult patients with pollen sensitivity were prospectively recruited. Patients were interviewed with a questionnaire including a list of pollen-associated foods. Patients were classified as having PFAS if they reported clear allergic symptoms compatible with PFAS. All participants underwent skin prick tests (SPT) to a panel of common aeroallergens, prick-to-prick tests with culprit fresh foods were performed in patients who gave consent. Self-reported PFAS was observed in 49 patients (19.3%). The most common culprit foods were kiwi, peach, tomato, melon and watermelon. Multiple logistic regression analysis showed that potential risk factors for PFAS were having asthma (OR=2.392, P=0.044) and tree pollen sensitization (OR=2.904, P=0.004). There were no significant differences in the SPT wheal sizes to individual pollen extracts between patients with and without PFAS with a positive SPT result for that pollen extract (P> 0.05). PFAS is frequent in pollen sensitized adults in Turkey. The most commonly implicated foods are kiwi, peach,tomato, melon and watermelon, in our geographical region. SPT wheal sizes to pollen extracts seems to be similar in patients with and without PFAS.

Peeling skin syndrome (PSS) type B is a rare recessive genodermatosis characterized by lifelong widespread, reddish peeling of the skin with pruritus. The disease is caused by small-scale mutations in the Corneodesmosin gene (CDSN) leading to premature termination codons. We report for the first time a Japanese case resulting from complete deletion of CDSN. Corneodesmosin was undetectable in the epidermis, and CDSN was unamplifiable by PCR. QMPSF analysis demonstrated deletion of CDSN exons inherited from each parent. Deletion mapping using microsatellite haplotyping, CGH array and PCR analysis established that the genomic deletion spanned 49-72 kb between HCG22 and TCF19, removing CDSN as well as five other genes within the psoriasis susceptibility region 1 (PSORS1) on 6p21.33. This observation widens the spectrum of molecular defects underlying PSS type B and shows that loss of these five genes from the PSORS1 region does not result in an additional cutaneous phenotype. © 2013 John Wiley & Sons A/S.

White-nose syndrome (WNS) has claimed the lives of millions of hibernating insectivorous bats in North America. Its etiologic agent, the psychrophilic fungus Geomyces destructans, causes skin lesions that are the hallmark of the disease. The fungal infection is characterized by a white powdery growth on muzzle, ears and wing membranes. While WNS may threaten some species of North American bats with regional extinction, infection in hibernating bats in Europe seems not to be associated with significant mortality. We performed histopathological investigations on biopsy samples of 11 hibernating European bats, originating from 4 different countries, colonized by G. destructans. One additional bat was euthanized to allow thorough examination of multiple strips of its wing membranes. Molecular analyses of touch imprints, swabs and skin samples confirmed that fungal structures were G. destructans. Additionally, archived field notes on hibernacula monitoring data in the Harz Mountains, Germany, over an 11-year period (2000-2011) revealed multiple capture-recapture events of 8 banded bats repeatedly displaying characteristic fungal colonization. Skin lesions of G. destructans-affected hibernating European bats are intriguingly similar to the epidermal lesions described in North American bats. Nevertheless, deep invasion of fungal hyphae into the dermal connective tissue with resulting ulceration like in North American bats was not observed in the biopsy samples of European bats; all lesions found were restricted to the layers of the epidermis and its adnexae. Two bats had mild epidermal cupping erosions as described for North American bats. The possible mechanisms for any difference in outcomes of G. destructans infection in European and North American bats still need to be elucidated.

Peeling skin syndrome is an autosomal recessive genodermatosis characterized by the shedding of the outer epidermis. In the acral form, the dorsa of the hands and feet are predominantly affected. Ultrastructural analysis has revealed tissue separation at the junction between the granular cells and the stratum corneum in the outer epidermis. Genomewide linkage analysis in a consanguineous Dutch kindred mapped the gene to 15q15.2 in the interval between markers D15S1040 and D15S1016. Two homozygous missense mutations, T109M and G113C, were found in TGM5, which encodes transglutaminase 5 (TG5), in all affected persons in two unrelated families. The mutation was present on the same haplotype in both kindreds, indicating a probable ancestral mutation. TG5 is strongly expressed in the epidermal granular cells, where it cross-links a variety of structural proteins in the terminal differentiation of the epidermis to form the cornified cell envelope. An established, in vitro, biochemical cross-linking assay revealed that, although T109M is not pathogenic, G113C completely abolishes TG5 activity. Three-dimensional modeling of TG5 showed that G113C lies close to the catalytic domain, and, furthermore, that this glycine residue is conserved in all known transglutaminases, which is consistent with pathogenicity. Other families with more-widespread peeling skin phenotypes lacked TGM5 mutations. This study identifies the first causative gene in this heterogeneous group of skin disorders and demonstrates that the protein cross-linking function performed by TG5 is vital for maintaining cell-cell adhesion between the outermost layers of the epidermis.

Observational analysis revealed a concerning frequency of scald burns secondary to instant noodles. A literature review reveals studies with small sample sizes of pediatric populations and analysis of container engineering. The adult cohort, treatments, and short-term outcomes have been neglected. Considering these deficiencies, we reviewed our institution's experience with burns secondary to instant noodles. Patient encounters due to instant noodle burns from January 1, 2007, through May 15, 2011, were reviewed. Demographics, burn characteristics, treatment, length of stay, number of operative interventions, and complications were analyzed. Eight hundred fifty-two patients were seen (460 were admitted) for scald burns of all pathogenesis. Of these, 121 (14%) were seen for burns secondary to noodles (63 men and 58 women). Of these, 48 were older than age 4 (group 1), and 73 were younger than age 4 (group 2). TBSA was 2.34 in group 1 and 1.64 in group 2 (P = .04). The most commonly burned areas in group 1 were extremities (n = 43) and in group 2 were chest (n = 32) and extremities (n = 31). Seven patients in group 1 and two patients in group 2 required operative intervention. Length of stay in groups 1 and 2 were 3.5 and 6 days, respectively. Noodle scald burns cause morbidity at all ages. Pediatric burns due to noodles are frequently managed conservatively but more often necessitate inpatient treatment. The nonpediatric population has larger TBSA and requires more frequent operative intervention. The morbidity of noodle burns is significant. Increased public education and container re-engineering is warranted.

The objective of this study was to determine the individual and combined effects of a high pH scald and a postpick chlorine dip on bacteria present on broiler carcasses. In each of 3 replications, a flock was sampled at several sites within a commercial broiler processing plant. Carcasses were sampled by whole carcass rinse before and after treated scalding at mean pH 9.89 or control scalding at mean pH 6.88. Other carcasses from the same flock run on both the treated and control scald lines were collected and sampled before and after a chlorine dip tank operated at mean total chlorine level of 83.3 mg/kg and pH 6.04. Rinses were cultured for numbers of Campylobacter and Escherichia coli and presence or absence of Salmonella. High pH scald was more effective than standard scald to lessen the prevalence and numbers of Campylobacter on broiler carcasses; a lower prevalence was maintained through the postpick chlorine dip tank. The pH of the scald tank made no difference in numbers of E. coli recovered from broiler carcasses at any tested point on the processing line. High pH scald was not more effective than standard scald to lessen Salmonella prevalence. Furthermore, it is unclear why the postpick chlorine dip effectively lessened Salmonella prevalence on only the control scald line. Although no evidence exists that these treatments have an additive effect when used in series, each treatment shows some promise individually. Further optimization may result in more effective decontamination of broiler carcasses.
Full Text Available Hereditary periodic fever syndromes are characterized by recurrent episodes of fever and inflammation with no known pathogenic or autoimmune cause. In humans, several genes have been implicated in this group of diseases, but the majority of cases remain unexplained. A similar periodic fever syndrome is relatively frequent in the Chinese Shar-Pei breed of dogs. In the western world, Shar-Pei have been strongly selected for a distinctive thick and heavily folded skin. In this study, a mutation affecting both these traits was identified. Using genome-wide SNP analysis of Shar-Pei and other breeds, the strongest signal of a breed-specific selective sweep was located on chromosome 13. The same region also harbored the strongest genome-wide association (GWA signal for susceptibility to the periodic fever syndrome (p(raw = 2.3 × 10⁻⁶, p(genome = 0.01. Dense targeted resequencing revealed two partially overlapping duplications, 14.3 Kb and 16.1 Kb in size, unique to Shar-Pei and upstream of the Hyaluronic Acid Synthase 2 (HAS2 gene. HAS2 encodes the rate-limiting enzyme synthesizing hyaluronan (HA, a major component of the skin. HA is up-regulated and accumulates in the thickened skin of Shar-Pei. A high copy number of the 16.1 Kb duplication was associated with an increased expression of HAS2 as well as the periodic fever syndrome (p < 0.0001. When fragmented, HA can act as a trigger of the innate immune system and stimulate sterile fever and inflammation. The strong selection for the skin phenotype therefore appears to enrich for a pleiotropic mutation predisposing these dogs to a periodic fever syndrome. The identification of HA as a major risk factor for this canine disease raises the potential of this glycosaminoglycan as a risk factor for human periodic fevers and as an important driver of chronic inflammation.

Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) are overlapping manifestations on a spectrum of acute drug-induced conditions associated with severe blistering, skin peeling, and multi-organ damage. TEN is an eruption resembling severe scalding, with ≥30% skin detachment. SJS is a mild form of TEN, characterized histologically by epidermal keratinocyte apoptosis with dermo-epidermal separation and extensive small blisters with <10% body surface skin detachment. The syndrome can be induced by numerous medications and typically occurs 1-4 weeks after the initiation of therapy. Granulysin is found in the lesions of patients with SJS/TEN and plays a significant pathogenic role in the condition, but the overall mechanisms linking medications, granulysin, and disease manifestations remain obscure. This paper reviews evidence suggesting that the different medications implicated in SJS/TEN have the common property of interacting and synergizing with endogenous retinoids (vitamin A and its congeners), in many instances causing the latter to accumulate in and damage the liver, the main storage organ for vitamin A. It is hypothesized that liver damage leads to the spillage of toxic retinoid compounds into the circulation, resulting in an endogenous form of hypervitaminosis A and cytotoxicity with widespread apoptosis, mediated by granulysin and recognized as SJS/TEN. Subject to testing, the model suggests that symptom worsening could be arrested at onset by lowering the concentration of circulating retinoids and/or granulysin via phlebotomy or plasmapheresis or by pharmacological measures to limit their expression.

Because of the escape of highly contaminated gut contents from the cloaca of positive carcasses, Campylobacter numbers recovered from broiler carcass skin samples increase during automated feather removal. Vinegar is known to have antimicrobial action. The objective of this study was to determine the effect of vinegar placed in the cloaca prior to feather removal on the numbers of Campylobacter recovered from broiler breast skin. Broilers were stunned, killed, and bled in a pilot processing plant. Vinegar was placed in the colons of the chickens prior to scalding. Carcasses were scalded, and Campylobacter numbers were determined on breast skin before and after passage through a commercial-style feather-picking machine. Campylobacter numbers recovered from the breast skin of untreated control carcasses increased during feather removal from 1.3 log CFU per sample prior to defeathering to 4.2 log afterward. Placement of water in the colon before scalding had no effect on Campylobacter numbers. Campylobacter numbers recovered from the breast skin of carcasses treated with vinegar also increased during defeathering but to a significantly lesser extent. Treated carcasses experienced only a 1-log increase from 1.6 log CFU per sample before feather removal to 2.6 log CFU per sample afterward. Application of an effective food-grade antimicrobial in the colon prior to scald can limit the increase in Campylobacter contamination of broiler carcasses during defeathering.
One factor that could impact the feasibility of commercial on-farm slaughter of broilers is the time delay from on-farm slaughter to scalding and defeathering in the commercial plant that could be 4 h or more. This experiment evaluated feather retention force (FRF) in broilers that were slaughtered ...
The implementation of on farm slaughter could eliminate potential animal welfare issues associated with cooping, transport, dumping, and shackling live broilers. This research evaluated evisceration efficiency and the microbiological implications of delaying scalding and defeathering for up to 8 h a...
Full Text Available This study deals with the foliar treatment by the fungicide triadimenol against barley scald. Results have shown that two or three triadimenol treatments have practically stopped the infection evolution. The disease have slightly extended with only one treatment. Moreover, other assessment showed that one, two or three triadimenol treatments were significantly associated to the same increase in the yield.

Abstract Cyclical thrombocytosis, acquired von Willebrand syndrome, aggressive non-melanoma skin cancers and other hydroxyurea complications have been reported in Philadelphia-negative myeloproliferative neoplasms (MPNs), but their incidence and clinical consequences have not been defined in a large cohort of patients. We conducted a retrospective analysis of 188 consecutive patients with MPNs specifically addressing the incidence of these complications. Cyclical thrombocytosis was documented in 29 patients (15%), the majority of whom were receiving hydroxyurea. Acquired von Willebrand syndrome was identified in 17 of the 84 screened patients (20%), but was not associated with any major bleeding complications. Non-melanoma skin cancers were reported in 51 patients (27%). Hydroxyurea-related fever occurred in nine of 149 patients (6%) who received hydroxyurea. Seventy-three patients (39%) experienced a total of 98 major thrombotic events, with the majority of these occurring prior to or within 3 months of the diagnosis. Cyclical thrombocytosis, acquired von Willebrand syndrome, aggressive non-melanoma skin cancers and other hydroxyurea-related complications are not infrequent in MPNs and have important clinical consequences for management.

The term 'sclerosing diseases of the skin' comprises specific dermatological entities, which have fibrotic changes of the skin in common. These diseases mostly manifest in different clinical subtypes according to cutaneous and extracutaneous involvement and can sometimes be difficult to distinguish from each other. The present guideline focuses on characteristic clinical and histopathological features, diagnostic scores and the serum autoantibodies most useful for differential diagnosis. In addition, current strategies in the first- and advanced-line therapy of sclerosing skin diseases are addressed in detail. Part 1 of this guideline provides clinicians with an overview of the diagnosis and treatment of localized scleroderma (morphea), and systemic sclerosis including overlap syndromes of systemic sclerosis with diseases of the rheumatological spectrum. © 2017 European Academy of Dermatology and Venereology.

Research was carried out to study the mode of action of diphenylamine (DPA) and 1-methylcyclopropene (1-MCP), on control of superficial scald of Granny Smith apples (Malus domestica Borkh.), and its relation with chemical compounds. Fruit was harvested from a commercial orchard in Chile, 182 and 189 days after full bloom and received the following treatments: DPA (2,000 ppm); 1-MCP (1.2 ppm) and control (no treatment). All fruit was stored for 4 or 6 months at 0 degree centigrade. A completely randomized factorial design was used (2 harvest dates by 3 post harvest treatments). Monthly measurements were made on maturity indices, ethylene production rate (EPR), scald related compounds [a-farnesene (AF), conjugated trienes (CT), total anti-oxidants (AO)], and cell membrane stability. Following 4 and 6 months of storage, plus 7 days at 20 degree centigrade, scald was evaluated. After 6 months, DPA-treated fruit, from both harvests, showed similar firmness, EPR and AO, compared to the control. However, AF and CT were lower, and cell membrane stability higher. Conversely, 1-MCP-treated fruit showed a noticeable EPR suppression and AF inhibition, along with higher firmness, lower CT and AO, compared to the control and DPA. Furthermore, cell membrane stability was superior to that of the control and similar to that of the DPA. Treated fruit (DPA and 1-MCP) showed an important reduction in scald compared to the control. The effect of 1-MCP on the investigated compounds and the reduction in scald, confirms that ethylene plays a major role on its development. (Author) 50 refs.
Full Text Available In humans, congenital and hereditary skin diseases associated with epidermal cell-cell separation (acantholysis are very rare, and spontaneous animal models of these diseases are exceptional. Our objectives are to report a novel congenital acantholytic dermatosis that developed in Chesapeake Bay retriever dogs. Nine affected puppies in four different litters were born to eight closely related clinically normal dogs. The disease transmission was consistent with an autosomal recessive mode of inheritance. Clinical signs occurred immediately after birth with superficial epidermal layers sloughing upon pressure. At three month of age, dogs exhibited recurrent superficial skin sloughing and erosions at areas of friction and mucocutaneous junctions; their coat was also finer than normal and there were patches of partial hair loss. At birth, histopathology revealed severe suprabasal acantholysis, which became less severe with ageing. Electron microscopy demonstrated a reduced number of partially formed desmosomes with detached and aggregated keratin intermediate filaments. Immunostaining for desmosomal adhesion molecules revealed a complete lack of staining for plakophilin-1 and anomalies in the distribution of desmoplakin and keratins 10 and 14. Sequencing revealed a homozygous splice donor site mutation within the first intron of PKP1 resulting in a premature stop codon, thereby explaining the inability to detect plakophilin-1 in the skin. Altogether, the clinical and pathological findings, along with the PKP1 mutation, were consistent with the diagnosis of ectodermal dysplasia-skin fragility syndrome with plakophilin-1 deficiency. This is the first occurrence of ectodermal dysplasia-skin fragility syndrome in an animal species. Controlled mating of carrier dogs would yield puppies that could, in theory, be tested for gene therapy of this rare but severe skin disease of children.

POEMS syndrome (an acronym of polyneuropathy, organomegaly, endocrinopathy, multiple myeloma and skin changes) is a paraneoplastic disorder related to an underlying plasma cell dyscrasia. The development of such a syndrome is rare and its association with calvarial plasmocytoma is even less common, with only two previous reported cases. We describe, in detail, an unusual presentation of cranial plasmocytoma associated with POEMS syndrome and briefly discuss the possible role of surgery in the management of this disease. We present the case of a 45-year-old Caucasian man who was admitted to our department presenting with progressive weakness in his lower limbs, enlarged lymph nodes and a large mass on the scalp with intense bone erosion. POEMS criteria were present and pathological studies confirmed a Castleman's variant plasmocytoma. Clinical status improved noticeably after the excision of the plasmocytoma and the treatment was completed with radiotherapy and steroid pulse therapy. Cranial vault plasmocytoma and its association with POEMS syndrome are rare conditions with few previously reported cases. Although the role of surgery is not clearly defined in POEMS syndrome guidelines, the fact that there seems to be a better prognosis and clinical outcome when surgery is used as a part of the management in POEMS syndrome with cranial vault plasmocytoma is worth discussing.

Insulin, as an anti-inflammatory drug, could not be freely used in patients who experienced trauma according to the degree of inflammation, because of the side effect of hypoglycemia. In vivo experimental evidence is lacking concerning whether the effect is dosage dependent and whether it relies on controlling hyperglycemia. By adjusting the dosage ratio of glucose and insulin, different dosages of insulin were used to treat severely scalded MODS rats to achieve uncontrolled or controlled hyperglycemia. One hundred forty rats with severe scalded were randomly divided into a hyperglycemia-controlled group, hyperglycemia-uncontrolled group, and control group. The levels of inflammation response indexes and major organ dysfunction indexes were measured and compared between groups. The blood indexes of inflammatory response and major organ dysfunction did not show statistical difference between hyperglycemia-controlled groups (A) and uncontrolled groups (B) in the same dosage of insulin (all P>0.05). The blood indexes of inflammatory response and major organ dysfunction demonstrated statistical difference in different dosages of insulin with hyperglycemia-controlled groups (A1-A3 groups) and hyperglycemia-uncontrolled groups (B1-B3 groups) (all Pcontrolling hyperglycemia. The effect of anti-inflammation and organ protection of insulin is dosage dependent in vivo; it does not rely on controlling hyperglycemia. Temporary traumatic hyperglycemia itself might not be detrimental to the body. Adjusting the ratio of insulin and glucose could provide a novel train of thought for freely treating patients with severe traumatic injury with different dosages of insulin according to the degree of inflammation.

Pediatric scald burns result in frequent emergency room visits and hospitalizations. We investigated whether cooking-related burns produce greater morbidity requiring more extensive care than noncooking burns. We performed a 6-y review at our free-standing children's hospital. Children aged cooking versus noncooking burns. The Mann-Whitney U test, a chi-square test, and the negative binomial were used to compare continuous, categorical, and count data between groups. Bivariate analysis was performed to identify risk factors among patients with adverse outcomes. We identified 308 patients; 262 (85%) cooking and 46 (15%) noncooking burns. Most patients were African-American males, with public insurance, and a median age of 2 y. Cooking burns preferentially occurred over the head, neck, and upper body; noncooking burns were distributed over the lower body (P 0.11). In subgroup analysis, semisolid and grease burns resulted in increased rates of wound contractures and/or limited mobility when compared with noncooking burns (P = 0.05 and P = 0.008, respectively). Patients with complications were more likely to have third degree burns and required more consults, longer hospitalization, and more surgical debridements and clinic visits. Most accidental scald burns occurred in young children during food preparation. Greater long-term morbidity was found in patients with semisolid and grease burns. This subset of children has a higher injury burden and requires extensive care in the acute and long-term setting. Copyright © 2015 Elsevier Inc. All rights reserved.
Full Text Available Feline viral plaques are uncommon skin lesions clinically characterized by multiple, often pigmented, and slightly raised lesions. Numerous reports suggest that papillomaviruses (PVs are involved in their development. Immunosuppressed and immunocompetent cats are both affected, the biological behavior is variable, and the regression is possible but rarely documented. Here we report a case of a FIV-positive cat with skin fragility syndrome and regressing multiple viral plaques in which the contemporary presence of two PV types (FcaPV2 and FcaPV3 was demonstrated by combining a quantitative molecular approach to histopathology. The cat, under glucocorticoid therapy for stomatitis and pruritus, developed skin fragility and numerous grouped slightly raised nonulcerated pigmented macules and plaques with histological features of epidermal thickness, mild dysplasia, and presence of koilocytes. Absolute quantification of the viral DNA copies (4555 copies/microliter of FcaPV2 and 8655 copies/microliter of FcaPV3 was obtained. Eighteen months after discontinuation of glucocorticoid therapy skin fragility and viral plaques had resolved. The role of the two viruses cannot be established and it remains undetermined how each of the viruses has contributed to the onset of VP; the spontaneous remission of skin lesions might have been induced by FIV status change over time due to glucocorticoid withdraw and by glucocorticoids withdraw itself.

Sea cucumber Apostichopus japonicus is an important economic species in China, which is affected by various diseases; skin ulceration syndrome (SUS) is the most serious. In this study, we characterized the transcriptomes in A. japonicus challenged with Vibrio splendidus to elucidate the changes in gene expression throughout the three stages of SUS progression. RNA sequencing of 21 cDNA libraries from various tissues and developmental stages of SUS-affected A. japonicus yielded 553 million raw reads, of which 542 million high-quality reads were generated by deep-sequencing using the Illumina HiSeq™ 2000 platform. The reference transcriptome comprised a combination of the Illumina reads, 454 sequencing data and Sanger sequences obtained from the public database to generate 93,163 unigenes (average length, 1,052 bp; N50 = 1,575 bp); 33,860 were annotated. Transcriptome comparisons between healthy and SUS-affected A. japonicus revealed greater differences in gene expression profiles in the body walls (BW) than in the intestines (Int), respiratory trees (RT) and coelomocytes (C). Clustering of expression models revealed stable up-regulation as the main pattern occurring in the BW throughout the three stages of SUS progression. Significantly affected pathways were associated with signal transduction, immune system, cellular processes, development and metabolism. Ninety-two differentially expressed genes (DEGs) were divided into four functional categories: attachment/pathogen recognition (17), inflammatory reactions (38), oxidative stress response (7) and apoptosis (30). Using quantitative real-time PCR, twenty representative DEGs were selected to validate the sequencing results. The Pearson's correlation coefficient (R) of the 20 DEGs ranged from 0.811 to 0.999, which confirmed the consistency and accuracy between these two approaches. Dynamic changes in global gene expression occur during SUS progression in A. japonicus. Elucidation of these changes is important

To observe the effects of astragalus polysaccharide (AP) on the intestinal mucosal morphology, level of secretory IgA (s-IgA) in intestinal mucus, and distribution of T lymphocyte subsets in Peyer's patch in rats with severe scald injury. One hundred and thirty SD rats were divided into sham injury group (SI, sham injured, n = 10), scald group (S, n = 30), low dosage group (LD, n = 30), moderate dosage group (MD, n = 30), and high dosage group (HD, n = 30) according to the random number table. Rats in the latter 4 groups were inflicted with 30% TBSA full-thickness scald on the back. From post injury hour 2, rats in groups LD, MD, and HD were intraperitoneally injected with 0.5 mL AP solution with the dosage of 100, 200, and 300 mg/kg each day respectively, and rats in group S were injected with 0.5 mL normal saline instead. Ten rats from group SI immediately after injury and 10 rats from each of the latter 4 groups on post injury day (PID) 3, 7, 14 were sacrificed, and their intestines were harvested. The morphology of ileal mucosa was examined after HE staining; the level of s-IgA in ileal mucus was determined with double-antibody sandwich ELISA method; the proportions of CD3⁺, CD4⁺, CD8⁺ T lymphocytes in Peyer's patches of intestine were determined with flow cytometer, and the proportion of CD4⁺ to CD8⁺ was calculated. Data were processed with one-way analysis of variance, analysis of variance of factorial design, and SNK test. (1) Villi in normal form and intact villus epithelial cells were observed in rats of group SI immediately after injury, while edema of villi and necrosis and desquamation of an enormous amount of villi were observed in groups with scalded rats on PID 3, with significant infiltration of inflammatory cells. On PID 7, no obvious improvement in intestinal mucosal lesion was observed in groups with scalded rats. On PID 14, the pathology in intestinal mucosa of rats remained nearly the same in group S, and it was alleviated obviously

To observe the effect of negative pressure therapy in the treatment of superficial partial-thickness scald in children. Three hundred and seven children with superficial partial-thickness scald hospitalized from August 2009 to May 2012 were divided into negative pressure therapy group (NPT, n = 145) and control group (C, n = 162) according to the random number table. Patients in group NPT were treated with negative pressure from within post injury day (PID) 3 to PID 9 (with -16 kPa pressure), while traditional occlusive dressing method was used in group C. Changes in body temperature, wound healing condition, frequency of dressing change were compared between group NPT and group C. Bacterial culture results of wounds were compared before and after treatment in group NPT. Volume of drained transudate per one percent of wound area was recorded in group NPT on PID 1 to PID 3. Data were processed with t test or chi-square test. The incidence of high fever was significantly lower in group NPT (26.9%, 39/145) than in group C (63.6%, 103/162, χ(2) = 41.419, P partial-thickness scald.

The aim of this study was to investigate the influence of additives such as plants belonging to Lamiaceae family (Thymus vulgaris, Carum carvi, Origanum vulgare, Ocimum basilicum, and Coriandrum sativum), scalded flour (SF) or scalded flour fermented with Lactobacillus plantarum LUHS135 (SFFLp) on the quality and acrylamide formation in wheat bread. The formation of acrylamide and bread quality significantly depended on the king of plants used and the amount of SF and SFFLp used. The additives of T. vulgaris and SF increased the content of acrylamide by 3.4-fold in comparison with bread prepared without SF, whereas the addition of SFFLp significantly reduced the content of acrylamide in bread, especially using 5% of SFFLp supplemented with O. vulgare and 15% of SFFLp supplemented with C. sativum (respectively by 40% and 29.4%) therefore could be recommended for safer bread production. The addition of 5% (from total wheat flour content) of scalded wheat flour fermented with Lactobacillus plantarum LUHS135 strain (SFFLp) with Origanum vulgare addition, and 5% or 10% of SFFLp prepared with Ocimum basilicum, and 15% of SFFLp prepared with Coriandrum sativum significantly reduce the content of acrylamide in wheat bread, therefore could be recommended for safer bread production. © 2018 Institute of Food Technologists®.

Severe burns result in significant skeletal muscle cachexia that impedes recovery. Activity of satellite cells, skeletal muscle stem cells, is altered following a burn injury and likely hinders regrowth of muscle. Severe burn injury induces satellite cell proliferation and fusion into myofibres with greater activity in muscles proximal to the injury site. Conditional depletion of satellite cells attenuates recovery of myofibre area and volume following a scald burn injury in mice. Skeletal muscle regrowth following a burn injury requires satellite cell activity, underscoring the therapeutic potential of satellite cells in the prevention of prolonged frailty in burn survivors. Severe burns result in profound skeletal muscle atrophy; persistent muscle atrophy and weakness are major complications that hamper recovery from burn injury. Many factors contribute to the erosion of muscle mass following burn trauma, and we have previously shown concurrent activation and apoptosis of muscle satellite cells following a burn injury in paediatric patients. To determine the necessity of satellite cells during muscle recovery following a burn injury, we utilized a genetically modified mouse model (Pax7 CreER -DTA) that allows for the conditional depletion of satellite cells in skeletal muscle. Additionally, mice were provided 5-ethynyl-2'-deoxyuridine to determine satellite cell proliferation, activation and fusion. Juvenile satellite cell-wild-type (SC-WT) and satellite cell-depleted (SC-Dep) mice (8 weeks of age) were randomized to sham or burn injury consisting of a dorsal scald burn injury covering 30% of total body surface area. Both hindlimb and dorsal muscles were studied at 7, 14 and 21 days post-burn. SC-Dep mice had >93% depletion of satellite cells compared to SC-WT (P satellite cell proliferation and fusion. Depletion of satellite cells impaired post-burn recovery of both muscle fibre cross-sectional area and volume (P satellite cells in the aetiology of lean

Skin fibroblasts isolated from two members of the same family with the cancer-prone disease Gardner's Syndrome (intestinal polyposis, colon cancer, bone and soft tissue tumors) showed enhanced sensitivity to the lethal effects of X-irradiation, ultraviolet light and mitomycin-C. These cells showed no liquid-holding type recovery following UV-irradiation of confluent cultures, but were normal in their capacity for UV-induced unscheduled DNA synthesis. UV survival was not influenced by post-irradiation incubation with caffeine. (orig.)

Playing video games causes physical and psychological stress, including increased heart rate and blood pressure and aggression-related feelings. Use of mobile phones is very popular in Japan, and frequent ringing is a common and intrusive part of Japanese life. Atopic eczema/dermatitis syndrome is often exacerbated by stress. Stress increases serum IgE levels, skews cytokine pattern towards Th2 type, enhances allergen-induced skin wheal responses, and triggers mast cell degranulation via substance P, vasoactive intestinal peptide and nerve growth factor. (1). In the video game study, normal subjects (n = 25), patients with allergic rhinitis (n = 25) or atopic eczema/dermatitis syndrome (n = 25) played a video game (STREET FIGHTER II) for 2 h. Before and after the study, allergen-induced wheal responses, plasma levels of substance P, vasoactive intestinal peptide and nerve growth factor, and in vitro production of total IgE, antihouse dust mite IgE and cytokines were measured. (2). In the mobile phone study, normal subjects (n = 27), patients with allergic rhinitis (n = 27) or atopic eczema/dermatitis syndrome (n = 27) were exposed to 30 incidences of ringing mobile phones during 30 min. Before and after the study, allergen-induced wheal responses, plasma levels of substance P, vasoactive intestinal peptide and nerve growth factor were measured. Playing video games had no effect on the normal subjects or the patients with allergic rhinitis. In contrast, playing video games significantly enhanced allergen-induced skin wheal responses and increased plasma levels of substance P, vasoactive intestinal peptide and nerve growth factors in the patients with atopic eczema/dermatitis syndrome. Moreover, playing video games enhanced in vitro production of total IgE and anti-house dust mite IgE with concomitant increased production of IL-4, IL-10 and IL-13 and decreased production of IFN-gamma and IL-12 in the patients with atopic eczema/dermatitis syndrome. However, exposure
Full Text Available Imaging mass spectrometry (IMS is a useful cutting edge technology used to investigate the distribution of biomolecules such as drugs and metabolites, as well as to identify molecular species in tissues and cells without labeling. To protect against excess water loss that is essential for survival in a terrestrial environment, mammalian skin possesses a competent permeability barrier in the stratum corneum (SC, the outermost layer of the epidermis. The key lipids constituting this barrier in the SC are the ceramides (Cers comprising of a heterogeneous molecular species. Alterations in Cer composition have been reported in several skin diseases that display abnormalities in the epidermal permeability barrier function. Not only the amounts of different Cers, but also their localizations are critical for the barrier function. We have employed our new imaging system, capable of high-lateral-resolution IMS with an atmospheric-pressure ionization source, to directly visualize the distribution of Cers. Moreover, we show an ichthyotic disease pathogenesis due to abnormal Cer metabolism in Dorfman-Chanarin syndrome, a neutral lipid storage disorder with ichthyosis in human skin, demonstrating that IMS is a novel diagnostic approach for assessing lipid abnormalities in clinical setting, as well as for investigating physiological roles of lipids in cells/tissues.

Peeling skin syndromes form a large and heterogeneous group of inherited disorders characterized by superficial detachment of the epidermal cornified cell layers, often associated with inflammatory features. Here we report on a consanguineous family featuring non-inflammatory peeling of the skin exacerbated by exposure to heat and mechanical stress. Whole exome sequencing revealed a homozygous nonsense mutation in FLG2, encoding filaggrin 2, which co-segregated with the disease phenotype in the family. The mutation was found to result in decreased FLG2 RNA levels as well almost total absence of filaggrin 2 in the patient epidermis. Filaggrin 2 was found to be expressed throughout the cornified cell layers and to co-localize with corneodesmosin which plays a crucial role in maintaining cell-cell adhesion in this region of the epidermis. Absence of filaggrin 2 in the patient skin was associated with markedly decreased corneodesmosin expression, which may contribute to the peeling phenotype displayed by the patients. Accordingly, using the dispase dissociation assay, we showed that FLG2 down-regulation interferes with keratinocyte cell-cell adhesion. Of particular interest, this effect was aggravated by temperature elevation, consistent with the clinical phenotype. Restoration of CDSN levels by ectopic expression rescued cell-cell adhesion.Taken together, the present data suggest that filaggrin 2 is essential for normal cell-cell adhesion in the cornified cell layers.

Objective: To observe effects of exogenous high mobility group protein box 1 (HMGB1) on angiogenesis in ischemic zone of early scald wounds of rats. Methods: Thirty-six Sprague-Dawley rats were divided into HMGB1 group and simple scald (SS) group according to the random number table, with 18 rats in each group. Comb-like copper mould was placed on the back of rats for 20 s after being immersed in 100 ℃ hot water for 3 to 5 min to make three ischemic zones of wound. Immediately after scald, rats in HMGB1 group were subcutaneously injected with 0.4 μg HMGB1 and 0.1 mL phosphate buffer solution (PBS), and rats in SS group were subcutaneously injected with 0.1 mL PBS from boarders of ischemic zone of scald wound. At post scald hour (PSH) 24, 48, and 72, 6 rats in each group were collected. Protein expressions of vascular endothelial growth factor (VEGF) in ischemic zone of wound at PSH 24, 48, and 72 and protein expressions of CD31 in ischemic zone of wound at PSH 48 and 72 were detected by immunohistochemistry. The number of microvessel in CD31 immunohistochemical sections of ischemic zone of wound at PSH 48 and 72 was calculated after observing by the microscope. The mRNA expressions of VEGF and CD31 in ischemic zone of wound were detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction at PSH 24, 48, and 72. Data were processed with analysis of variance of factorial design, t test, and Bonferroni correction. Results: (1) At PSH 24, 48, and 72, protein expressions of VEGF in ischemic zone of wound of rats in HMGB1 group were significantly higher than those of rats in SS group ( t =7.496, 4.437, 5.402, P zone of wound of rats in HMGB1 group were 0.038 8±0.007 9 and 0.057 7±0.001 2 respectively, significantly higher than 0.013 4±0.004 9 and 0.030 3±0.004 0 of rats in SS group ( t =10.257, 15.055, P zone of wound of rats in HMGB1 group was obviously more than that of rats in SS group ( t =3.536, 4.000, P zone of wound of

Full Text Available Abstract Toxic epidermal necrolysis (TEN and Stevens Johnson Syndrome (SJS are severe adverse cutaneous drug reactions that predominantly involve the skin and mucous membranes. Both are rare, with TEN and SJS affecting approximately 1or 2/1,000,000 annually, and are considered medical emergencies as they are potentially fatal. They are characterized by mucocutaneous tenderness and typically hemorrhagic erosions, erythema and more or less severe epidermal detachment presenting as blisters and areas of denuded skin. Currently, TEN and SJS are considered to be two ends of a spectrum of severe epidermolytic adverse cutaneous drug reactions, differing only by their extent of skin detachment. Drugs are assumed or identified as the main cause of SJS/TEN in most cases, but Mycoplasma pneumoniae and Herpes simplex virus infections are well documented causes alongside rare cases in which the aetiology remains unknown. Several drugs are at "high" risk of inducing TEN/SJS including: Allopurinol, Trimethoprim-sulfamethoxazole and other sulfonamide-antibiotics, aminopenicillins, cephalosporins, quinolones, carbamazepine, phenytoin, phenobarbital and NSAID's of the oxicam-type. Genetic susceptibility to SJS and TEN is likely as exemplified by the strong association observed in Han Chinese between a genetic marker, the human leukocyte antigen HLA-B*1502, and SJS induced by carbamazepine. Diagnosis relies mainly on clinical signs together with the histological analysis of a skin biopsy showing typical full-thickness epidermal necrolysis due to extensive keratinocyte apoptosis. Differential diagnosis includes linear IgA dermatosis and paraneoplastic pemphigus, pemphigus vulgaris and bullous pemphigoid, acute generalized exanthematous pustulosis (AGEP, disseminated fixed bullous drug eruption and staphyloccocal scalded skin syndrome (SSSS. Due to the high risk of mortality, management of patients with SJS/TEN requires rapid diagnosis, evaluation of the prognosis

Full Text Available We describe the case of a patient who underwent craniectomy for hemorrhage of the left parietal lobe. Three weeks later, orthostatic memory impairment was detected as initial symptom of sinking skin flap syndrome (SSFS. This deficit was examined by neuropsychological testing and associated with a posture-dependent increase in the delta/alpha ratio at the F3 electrode, an electroencephalographic (EEG index related to brain hypoperfusion. This EEG spectral alteration was detected in a brain region that includes the left dorsolateral prefrontal cortex, an area known to be involved in memory processing; therefore we hypothesize that SSFS induced reversible hypoperfusion of this otherwise undamaged cortical region. Neither of these findings was present after cranioplasty. This case suggests that SSFS may induce neuropsychological deficits potentially influencing outcome in the postacute phase and is further evidence supporting the clinical benefits of early cranioplasty.
Full Text Available In this study, psychological tests such as Visual Analogue Pain Scale, Verbal Pain Scale, Beck Depression Inventory, Beck Anxiety Inventory, Hamilton Depression Rating Scale and Hamilton Anxiety Scale were applied to the selected healthy subjects and patients with Fibromyalgia Syndrome (FMS in Suleyman Demirel University, Faculty of Medicine, Department of Physical Medicine and Rehabilitation and the scores were recorded. A measurement system was established in the same department of the university to measure the sympathetic skin response (SSR from the subjects. The SSR was measured and recorded. The parameters such as latency time, maximum amplitude and the elapsed time were calculated by using Matlab software from the recorded SSR data. SSR parameters were added to the scores and diagnosis accuracy percentages of the FMS calculated by using artificial neural networks (ANNs. Obtained results from the simulations showed that the specified parameters of the SSR and FMS were concerned and these parameters can be used as a diagnostic method in FMS.
Full Text Available The present work analyzes skin burns from spills of hot rice and milk products. The traditional Norwegian rice porridge serves as an example. By testing spills on objects emulating an arm, it was concluded that spills were seldom thinner than 3 mm, and stayed in place due to the viscosity of the porridge for more than one minute. The Pennes bioheat equation was solved numerically for such spills, including heat conduction to the skin and convective heat losses from the porridge surface. Temperatures were analyzed in the porridge and skin layers, and the resulting skin injury was calculated based on the basal layer temperature. Parameters influencing burn severity, such as porridge layer thickness, porridge temperature, removal of the porridge and thermal effects of post scald tempered (15 °C water cooling were analyzed. The spilled porridge resulted in a prolonged heat supply to the skin, and the skin injury developed significantly with time. The porridge temperature turned out to be the most important injury parameter. A 70 °C porridge temperature could develop superficial partial-thickness burns. Porridge temperatures at processing temperatures nearly instantly developed severe burns. It was demonstrated that prompt removal of the hot porridge significantly reduced the injury development. The general advice is to avoid serving porridge and similar products at temperatures above 65 °C and, if spilled on the skin, to remove it quickly. After such scald incidents, it is advised to cool the injured area by tempered water for a prolonged period to stimulate healing.

The objective of this study was to investigate the epidemiological characteristics of scalds induced by "guo lian kang" (literally "stove connected to bed") in children. The demographic, burn features, outcome, and other information of 0-14-year-old children with "guo lian kang"-induced scalds admitted to the burn treatment center of the 322 Hospital of the People's Liberation Army in Datong from 30 September 2001 to 31 December 2011 were analyzed. Among the 1993 children clearly documented with scalds due to hot liquid in vessels, 795 (39.89%) had burns due to "guo lian kang." The proportion of the pediatric burns caused by "guo lian kang" was 55.56% in 2002 and 37.30% in 2011, with a decreasing trend. One-year-old children accounted for the highest proportion of children with burns due to "guo lian kang" (male:female=1.54:1). Scalding mostly occurred from October to May; the most common times were around 8:00 AM, 11:00 AM, and 7:00 PM. Most scalds occurred on the upper limbs, 90.22% of which were dermal burns. The median burn area was 11% of the total body surface area. The burn agent was mainly hot water in pots. Scalding mostly occurred when the children accidentally sat on, or fell or stepped into the pot while playing. Among the children with "guo lian kang"-induced scalds, up to 42.26% of the children did not receive any treatment before hospital admission, and 18.86% of the children were admitted to the hospital ≥6h after the occurrence of burns. In addition, 74.97% of the children's families can afford the medical expenses, while 5.28% abandoned treatment because of financial difficulties. There were no significant differences between children with scalds caused by "guo lian kang" and scalds caused due to other reasons considering the age and sex. Compared to scalds due to other reasons, children with "guo lian kang"-induced scalds had greater burn area and depth, shock incidence, surgery rate, blood transfusion rate, length of hospital stay, and

Full Text Available Abstract Introduction Anti-neutrophil cytoplasmic antibody-associated vasculitis has been associated with many drugs and it is a relatively rare side effect of the antihypertensive drug hydralazine. The diagnosis and management of patients who have anti-neutrophil cytoplasmic antibody-associated vasculitis may be challenging because of its relative infrequency, variability of clinical expression and changing nomenclature. The spectrum of anti-neutrophil cytoplasmic antibody-associated vasculitis is wide and can be fatal. This case documents a 62-year-old woman who presented with hydralazine-induced anti-neutrophil cytoplasmic antibody-positive renal vasculitis with a puzzling cutaneous rash. Case presentation We report a rare case of hydralazine-induced anti-neutrophil cytoplasmic antibody-associated vasculitis in a 62-year-old Caucasian woman who presented with a vasculitic syndrome with a sore throat, mouth ulcers and otalgia after several months of constitutional symptoms. She then proceeded to develop a rash over her right lower limb. Clinically, the rash had features to suggest Sweet’s syndrome, but also had some appearances consistent with embolic phenomena and did not have the appearance of palpable purpure usually associated with cutaneous vasculitis. Differential diagnoses were hydralazine-associated Sweet’s syndrome, streptococcal-induced cutaneous eruption or an unrelated contact dermatitis. A midstream urine sample detected glomerular blood cells in the setting of anti-neutrophil cytoplasmic antibody-positive renal vasculitis and Streptococcus pyogenes bacteremia. A renal biopsy revealed a pauci-immune, focally necrotizing glomerulonephritis with small crescents. Her skin biopsy revealed a heavy neutrophil infiltrate involving the full thickness of the dermis with no evidence of a leucocytoclastic vasculitis, but was non-specific. She was initially commenced on intravenous lincomycin for her bloodstream infection and subsequently

Apostichopus japonicus is one of the most important aquaculture species in China. Skin ulceration syndrome (SUS) of sea cucumber is a common and serious disease affected the development of A. japonicus culture industry. To better understand the response mechanisms of A. japonicus during SUS progression, the protein variations in the body wall of A. japonicus at different stages of SUS were investigated by a comparative proteomic approach based on isobaric tags for relative and absolute quantification. A total of 1449 proteins were identified from the samples at different SUS stages. Among these proteins, 145 proteins were differentially expressed in the SUS-related samples compared to those of healthy A. japonicus. These differentially expressed proteins involved a wide range of functions. Among these differentially expressed proteins, only two proteins, alpha-5-collagen and an unknown function protein, were differentially expressed during the whole progression of SUS compared with healthy A. japonicus. In addition, ATP synthase subunit beta (ATP5β) interacted with a variety of proteins with different functions during the SUS progression. These results implied that alpha-5-collagen and ATP5β could play important roles during the SUS progression of A. japonicus. Our study provided a new sight to understand the molecular responses of sea cucumber during the SUS progression and accumulated data for the prevention of SUS in sea cucumber aquaculture. The current study aimed to reveal how the body wall of Apostichopus japonicus response to skin ulceration syndrome (SUS). To the best of our knowledge, this is the first proteomic study analyzing the differences in protein profile of sea cucumber during the whole SUS progression. By analyzing the expression differences of the proteome via isobaric labeling-based quantitative proteomic, we identified some proteins which may play important roles during the SUS progression. According to the enrichment analyses of these
Full Text Available The present work analyzes scald burns from hot beverages, such as coffee and tea, spilled on the lap, i.e., an incident that may occur in daily life. The Pennes bioheat equation is solved numerically for small spills wetting the clothing, i.e., the fabric prevents the spilled liquid from draining away. Temperatures are analyzed in the wetted fabric and the skin layers and the resulting skin injury is calculated based on the basal layer temperature. Parameters influencing burn severity, such as clothing thickness, liquid temperature, removal of fabric and thermal effects of post scald water cooling are analyzed. The fabric cools the water some but represents a threat since the entrapped water results in a prolonged heat supply. The liquid temperature turned out to be the most important injury parameter, where liquid temperature of about 80–85 °C seems to be a limit for developing superficial partial-thickness burns in the present minimum case, i.e., where the liquid just wets the fabric. Spilling water in excess of just wetting the fabric, more severe burns will develop at lower liquid temperatures due to the prolonged heat supply. Higher liquid temperatures will nearly instantly develop more severe burns. It is demonstrated that removal of the clothing within the first seconds after the spill may significantly reduce the scalding severity. The general advice is therefore to avoid excessive heating of beverages and, if the beverage is spilled, to quickly remove the wetted clothing. Prolonged tempered water cooling is advised to improve the healing processes.

A 54-year-old Japanese woman had repetitive superficial skin peeling and ensuing erythematous changes in the sites since infancy. Her parents had a consanguineous marriage, and she was the only individual affected in her family tree. The erythematous changes seemed to worsen in the summer. Histologically, hyperkeratosis and splitting of the epidermis within the stratum corneum was noted, and electron microscopy revealed shedding of corneal cells in the horny layer and normal-looking corneodesmosomes. Gene analysis revealed a homozygous missense mutation at c.1358G>A in CDSN. Electron microscopic examination of the length and number of corneodesmosomes revealed statistically significant shortness and sparsity in the affected individual (mean ± SD 386.2 ± 149.5 nm) compared with that of an age- and site-matched control (406.6 ± 182.3 nm). We speculate that this size shrinkage of corneodesmosomes might be the result of a missense mutation of CDSN and that this could be one of the factors contributing to the pathological process of skin peeling.

Vascular Ehlers-Danlos syndrome (vEDS) is a dominantly inherited connective tissue disorder caused by mutations in the COL3A1 gene that encodes type III collagen (COLLIII), which is the major expressed collagen in blood vessels and hollow organs. The majority of disease-causing variants in COL3A1 are glycine substitutions and in-frame splice mutations in the triple helix domain that through a dominant negative effect are associated with the severe clinical spectrum potentially lethal of vEDS, characterized by fragility of soft connective tissues with arterial and organ ruptures. To shed lights into molecular mechanisms underlying vEDS, we performed gene expression profiling in cultured skin fibroblasts from three patients with different structural COL3A1 mutations. Transcriptome analysis revealed significant changes in the expression levels of several genes involved in maintenance of cell redox and endoplasmic reticulum (ER) homeostasis, COLLs folding and extracellular matrix (ECM) organization, formation of the proteasome complex, and cell cycle regulation. Protein analyses showed that aberrant COLLIII expression is associated with the disassembly of many structural ECM constituents, such as fibrillins, EMILINs, and elastin, as well as with the reduction of the proteoglycans perlecan, decorin, and versican, all playing an important role in the vascular system. Furthermore, the altered distribution of the ER marker protein disulfide isomerase PDI and the strong reduction of the COLLs-modifying enzyme FKBP22 are consistent with the disturbance of ER-related homeostasis and COLLs biosynthesis and post-translational modifications, indicated by microarray analysis. Our findings add new insights into the pathophysiology of this severe vascular disorder, since they provide a picture of the gene expression changes in vEDS skin fibroblasts and highlight that dominant negative mutations in COL3A1 also affect post-translational modifications and deposition into the ECM of

Definitive diagnosis of the bat disease white-nose syndrome (WNS) requires histologic analysis to identify the cutaneous erosions caused by the fungal pathogen Pseudogymnoascus [formerly Geomyces] destructans (Pd). Gross visual inspection does not distinguish bats with or without WNS, and no nonlethal, on-site, preliminary screening methods are available for WNS in bats. We demonstrate that long-wave ultraviolet (UV) light (wavelength 366-385 nm) elicits a distinct orange-yellow fluorescence in bat-wing membranes (skin) that corresponds directly with the fungal cupping erosions in histologic sections of skin that are the current gold standard for diagnosis of WNS. Between March 2009 and April 2012, wing membranes from 168 North American bat carcasses submitted to the US Geological Survey National Wildlife Health Center were examined with the use of both UV light and histology. Comparison of these techniques showed that 98.8% of the bats with foci of orange-yellow wing fluorescence (n=80) were WNS-positive based on histologic diagnosis; bat wings that did not fluoresce under UV light (n=88) were all histologically negative for WNS lesions. Punch biopsy samples as small as 3 mm taken from areas of wing with UV fluorescence were effective for identifying lesions diagnostic for WNS by histopathology. In a nonlethal biopsy-based study of 62 bats sampled (4-mm diameter) in hibernacula of the Czech Republic during 2012, 95.5% of fluorescent (n=22) and 100% of nonfluorescent (n=40) wing samples were confirmed by histopathology to be WNS positive and negative, respectively. This evidence supports use of long-wave UV light as a nonlethal and field-applicable method to screen bats for lesions indicative of WNS. Further, UV fluorescence can be used to guide targeted, nonlethal biopsy sampling for follow-up molecular testing, fungal culture analysis, and histologic confirmation of WNS.

Definitive diagnosis of the bat disease white-nose syndrome (WNS) requires histologic analysis to identify the cutaneous erosions caused by the fungal pathogen Pseudogymnoascus [formerly Geomyces] destructans (Pd). Gross visual inspection does not distinguish bats with or without WNS, and no nonlethal, on-site, preliminary screening methods are available for WNS in bats. We demonstrate that long-wave ultraviolet (UV) light (wavelength 368–385 nm) elicits a distinct orange–yellow fluorescence in bat-wing membranes (skin) that corresponds directly with the fungal cupping erosions in histologic sections of skin that are the current gold standard for diagnosis of WNS. Between March 2009 and April 2012, wing membranes from 168 North American bat carcasses submitted to the U.S. Geological Survey National Wildlife Health Center were examined with the use of both UV light and histology. Comparison of these techniques showed that 98.8% of the bats with foci of orange–yellow wing fluorescence (n = 80) were WNS-positive based on histologic diagnosis; bat wings that did not fluoresce under UV light (n = 88) were all histologically negative for WNS lesions. Punch biopsy samples as small as 3 mm taken from areas of wing with UV fluorescence were effective for identifying lesions diagnostic for WNS by histopathology. In a nonlethal biopsy-based study of 62 bats sampled (4-mm diameter) in hibernacula of the Czech Republic during 2012, 95.5% of fluorescent (n = 22) and 100% of nonfluorescent (n = 40) wing samples were confirmed by histopathology to be WNS positive and negative, respectively. This evidence supports use of long-wave UV light as a nonlethal and field-applicable method to screen bats for lesions indicative of WNS. Further, UV fluorescence can be used to guide targeted, nonlethal biopsy sampling for follow-up molecular testing, fungal culture analysis, and histologic confirmation of WNS.

Full Text Available Revesz syndrome is a rare variant of dyskeratosis congenita and is characterized by bilateral exudative retinopathy, alterations in the anterior ocular segment, intrauterine growth retardation, fine sparse hair, reticulate skin pigmentation, bone marrow failure, cerebral calcification, cerebellar hypoplasia and psychomotor retardation. Few patients with this syndrome have been reported, and significant clinical variations exist among patients. This report describes the first Brazilian case of Revesz syndrome and its ocular and clinical features.
Full Text Available Costello syndrome is a rare, distinctive, multiple congenital anomaly syndrome, characterized by soft, loose skin with deep palmar and plantar creases, loose joints, distinctive coarse facial features and skeletal and cardiac abnormalities. The affected patients have a predisposition to develop malignancy, developmental delays and mental retardation. Recently, a 7-year-old male child born to normal nonconsanguineous parents presented to us with abnormal facial features, arrhythmia, mitral valve dysfunction and growth retardation. His cutaneous examination revealed lax and pigmented skin over hands and feet with deep creases, acanthosis nigricans and short curly hairs. Its differentiation from other syndromes with similar clinical features is discussed in this article.

'Diffuse skin browning' (DSB) is a physiological disorder that affects Golden Delicious apples treated with 1-methylcyclopropene (1-MCP). Although a very high incidence is found, very little is known about the etiology of this disorder. This study aims to provide an understanding of the causes of this disorder and prevent it. A very high incidence of DSB was found in 1-MCP-treated apples independent of the location of the orchard. Similar to superficial scald, harvest maturity determines the DSB incidence, with the more mature fruit being less sensitive. The 1-MCP dose (156 nL L(-1) or 625 nL L(-1)) and the temperature at which the 1-MCP treatment was applied (0.5 or 20 °C) did not affect the incidence of DSB. Diphenylamine (DPA) treatment did not prevent DSB, contrary to superficial scald. Additionally, controlled atmosphere storage only partially reduced the incidence of DSB, whereas progressive cooling strategies completely inhibited DSB occurrence. A direct correlation was found between the sensitivity of the Golden Delicious clone to russeting and its sensitivity to develop DSB during storage. Our results indicated that DSB and superficial scald are two different disorders involving different oxidative processes. DSB can be prevented by progressive cooling and selection of russeting-resistant clones. 2010 Society of Chemical Industry

The formation of single-strand breaks by near-ultraviolet light at 313 nm and by aerobic gamma-rays was compared for skin fibroblast monolayer cultures from 4 normal donors (NF) and 8 patients with Bloom's syndrome (BS) by the alkaline elution method. In 6 of 8 BS strains, the number of breaks induced by near-ultraviolet light, 2.25 kJ/sq m, at 0 degrees was comparable to NF, while elevated breakage was observed in BS strains HG 369 and HG 916. Breakage frequencies were increased substantially in 6 of 8 BS strains relative to NF when the near-ultraviolet light exposure was at 37 degrees. BS strain GM 2520 represents an exception since normal breakage frequencies were induced both at 0 degrees and 37 degrees. Aerobic gamma-rays (75 R) induced comparable numbers of single-strand breaks in BS and NF strains at 0 degrees. The breakage frequencies were reduced an average of 17% in NF when the same dose was given at 30 degrees followed by 6 min incubation. Under the same conditions, the breakage frequencies were on the average reduced by 42% relative to 0 degrees in the BS strains, indicating that they possess normal or possibly slightly increased capacities for the rejoining of gamma-ray-induced breaks

Generalized peeling skin syndrome (PSS) is an autosomal recessive genodermatosis characterized by lifelong, continuous shedding of the upper epidermis. Using whole-genome homozygozity mapping and whole-exome sequencing, we identified a novel homozygous missense mutation (c.229C>T, R77W) within the CHST8 gene, in a large consanguineous family with non-inflammatory PSS type A. CHST8 encodes a Golgi transmembrane N-acetylgalactosamine-4-O-sulfotransferase (GalNAc4-ST1), which we show by immunofluorescence staining to be expressed throughout normal epidermis. A colorimetric assay for total sulfated glycosaminoglycan (GAG) quantification, comparing human keratinocytes (CCD1106 KERTr) expressing wild type and mutant recombinant GalNAc4-ST1, revealed decreased levels of total sulfated GAGs in cells expressing mutant GalNAc4-ST1, suggesting loss of function. Western blotting revealed lower expression levels of mutant recombinant GalNAc4-ST1 compared to wild type, suggesting that accelerated degradation may result in loss of function, leading to PSS type A. This is the first report describing a mutation as the cause of PSS type A. Copyright © 2012 Elsevier Inc. All rights reserved.

Full Text Available Burning mouth syndrome is a condition characterized by chronic orofacial pain without any mucosal abnormalities or other organic disease. There are numerous synonyms for this ailment such as stomatodynia, stomatopyrosis, glossodynia, glossopyrosis, sore mouth, sore tongue, oral dysesthesia, and scalding mouth syndrome. Patients usually present with burning, stinging, or numbness on the tongue or other areas of oral mucosa. The complex etiology and lack of characteristic signs and symptoms makes the diagnosis difficult. As a result of which managing such patients become a herculean task. Moreover, lack of understanding of the disease leads to misdiagnosis and unnecessary referral of patients. In this article, the authors have described the etiopathogenesis, diagnostic algorithm and management of this confusing ailment.

Severe burn induces biochemical mediators such as reactive oxygen species that leads to lipid peroxidation which may have a key role in formation of acute lung injury (ALI). Sildenafil is a selective and potent inhibitor of cyclic guanosine monophosphate specific phosphodiesterase-5. Sildenafil preserves alveolar growth, angiogenesis, reduces inflammation and airway reactivity. The purpose of the present study was to evaluate the effects of different dosages of sildenafil in ALI due to severe scald burn in rats. Twenty-four rats were subjected to 30% total body surface area severe scald injury and were randomly divided into three equal groups as follow: control, 10 and 20mg/kg sildenafil groups. Levels of malondialdehyde (MDA), activities of glutathione peroxidase (Gpx), catalase (Cat), total oxidative stress (TOS), and total antioxidative capacity (TAC) were measured in both tissues and serums. Oxidative stress index (OSI) was calculated. A semi-quantitative scoring system was used for the evaluation of histopatological findings. Sildenafil increased Gpx, Cat, TAC and decreased MDA, TOS and OSI. Sildenafil decreased inflammation scores in lungs. Our results reveal that sildenafil is protective against scald burn related ALI by decreasing oxidative stress and inflammation and the dosage of 10mg/kg could be apparently better than 20mg/kg.

Skin tightening describes the treatment of skin laxity via radiofrequency (RF), ultrasound, or light-based devices. Skin laxity on the face is manifested by progressive loss of skin elasticity, loosening of the connective tissue framework, and deepening of skin folds. This results in prominence of submandibular and submental tissues. Genetic factors (chronological aging) and extrinsic factors (ultraviolet radiation) both contribute to skin laxity. There are many RF, ultrasound, and light-based devices directed at treating skin laxity. All of these devices target and heat the dermis to induce collagen contraction. Heating of the dermis causes collagen denaturation and immediate collagen contraction in addition to long-term collagen remodeling. Via RF, light, or ultrasound, these skin tightening devices deliver heat to the dermis to create new collagen and induce skin tightening. This chapter will provide an overview of the various skin tightening devices. Copyright © 2011 S. Karger AG, Basel.
Full Text Available Rhynchosporium commune (formerly known as Rhynchosporium secalis, the causal agent of scald disease on barley, is known to spread asexually by splash dispersed conidia. However, there are multiple lines of evidence for the possibility of a clandestine sexual cycle occurrence in this species including extensive genotypic diversity, equal distribution of mating type alleles across the world and expression of mating type genes. In the current study, the potential for the occurrence of a sexual cycle amongst the Iranian population of R. commune was assessed by analyzing distribution and frequency of the mating type alleles at both micro and macro-spatial scales. A total of 95 single-conidial R. commune isolates were obtained from different barley fields in Kurdistan province. Previously designed primers were applied in a multiplex PCR assay to study distribution and frequency of the mating type alleles within and between populations. Totally, 67 isolates were determined as MAT1-1 and the remaining 28 isolates as MAT1-2 throughout the sampling counties. The results obtained at a macro-spatial scale revealed that unlike Kamyaran county (both MAT1-1 and MAT1-2 at an equal ratio, an unequal distribution of mating type genes was dominant among R. commune isolates in both Mariwan and Dehgolan counties. Our findings support a predominantly asexual reproduction for Mariwan and Dehgolan counties and the possibility of sexual stage occurrence in Kamyarna county.

A preventable subgroup of burn injuries is scalds sustained from motor vehicle radiators. This study was to determine changes in trends in epidemiology of such injuries and to discuss whether current and other prevention efforts proposed previously require reinforcement. We conducted a retrospective study (February 2007-August 2015) of all motor vehicle-related burn referrals to our regional burns service. 68 cases of motor vehicle radiator burns were identified. Male to female ratio was 65:3. Mean age was 35.1 (range = 9-71). Most cases occurred in the summer months (22/68 = 32.4%). 65 cases (95.6%) involved car radiators. 66% of injuries resulted from actively removing the pressure cap of an overheated radiator in the motor vehicle. Mean total burn surface area (%TBSA) was 2.1% (range = 0.5- 11%). The depths of burn injuries were mostly superficial partial thickness. Face, chest and upper limbs were the most common sites of injury. Mean healing time was 14.2 days (range = 4-60). Following the introduction of safety measures by vehicle manufacturers, motor vehicle radiator burns in this era are mostly minor injuries and can be potentially managed conservatively as an outpatient. This contrasts with findings from previous studies over a decade ago of larger, more significant injuries requiring admission and surgery. Whilst manufacturers have installed safety measures into the design of radiator caps, our findings suggest that re-educating the public to allow a period of cooling prior to opening caps should be reinforced.

Full Text Available Sneddon’s syndrome is usually characterized by the association of an ischemic cerebrovascular disease and a widespread livedo reticularis. The incidence of Sneddon syndrome is 4/1000 000. We present 42-year-old woman with livedo reticularis, recurrence ischaemic cerebrovascular accidents, two repetitive miscarriages and positive anti-2GPi antibodies. Skin biopsy specimens reveal inflammatory changes of small- to medium-sized arteries and subendothelial proliferation and fibrosis. The diagnosis Sneddon syndrome is confirmed by skin biopsy, and MR evidence. We suggest that anti-2GPi antibodies may be pathophysiologically related to the clinical manifestation observed in some patients with Sneddon syndrome.

Full Text Available Severe burn shock remains an unresolved clinical problem with an urgent need to explore novel therapeutic treatments. Intracellular β-catenin, through interaction with other proteins, has been reported to be able to regulate the size of cutaneous wounds. Higher expression of β-catenin is associated with larger sized wounds. However, the identification of serum β-catenin complex is difficult and has been rarely reported. The exploitation of more binding partners can contribute to uncovering the exact mechanisms behind serum β-catenin mediated biological effects. Here, we describe a method that consists of immunoprecipitation, SDS-PAGE, in-gel digestion, and nanoLC coupled to LCMS-IT-TOF for the investigation of serum β-catenin complex in mice scald model. Among selected gel bands obtained from the protein gels, a total of 31 peptides were identified and sequenced with high statistical significance (p<0.01. Three proteins (alpha-2-marcoglobulin, serine protease inhibitor A3K, and serine protease inhibitor A1A were identified and validated with high reliability and high reproducibility. It was inferred that these proteins might interact with serum β-catenin, which could affect the wound healing resulting from burn shock. Our study demonstrated that the on-line coupling of nano-LC with a LCMS-IT-TOF mass spectrometer was capable of sensitive and automated characterization of the serum β-catenin complex in mice scald model.

This chapter reviews the development of skin cancer associated with radiation, focusing on the knowledge of A-bomb radiation-induced skin cancer. Since the discovery of X radiation in 1895, acute and chronic radiation dermatitis has been the first matter of concern. Then, in 1902, skin cancer found among radiological personnel has posed a social problem. In earlier study determining the relationship between skin cancer and A-bomb radiation, there is no increase in the incidence of either skin cancer or precancerous condition during the first 20 years after A-bombing. More recent studies have showed that there is a significant correlation between the incidence of skin cancer and distance from the hypocenter; and the incidence of skin cancer is found to be remarkably increased since 1975 in the group exposed at ≤2,000 m. Excess relative risk is 2.2 at one Gy dose. The incidence of skin cancer is also found to be extremely increased with aging. Relative risk is high in younger A-bomb survivors at the time of exposure. Histologically, basal cell carcinoma is more senstitive to ionizing radiation than squamous cell carcinoma. (N.K.)

Full Text Available Michelin tire baby syndrome (MTBS, is a rare genodermatosis, characterized by generalized folding of excess skin and may be associated with various phenotypic abnormalities. The pathogenesis of this condition is unclear. Various congenital anomalies can be associated with it. It may be a clinical finding associated with various syndromes. Diagnosis is mainly clinical, and skin folds gradually diminish and disappear with age without any intervention. Here, we report a case of MTBS associated with convergent squint and hydrocephaly.
In this work, we present a novel specific method for absolute quantification of the midichloriacea associated with RMS in O. mykiss, based on a quantitative PCR approach. The qPCR method was tested on healthy skin, on lesions when present and on organ samples (heart, liver, spleen, intestine, kidney from ten fish. Our work shows, for the first time, that the midichloriacea is present not only in skin lesions but also in organs of affected fish. Further studies are needed to prove whether this bacterium is actually involved in the pathology.

Skin and soft tissue infections (SSTIs) caused by mupirocin-resistant Staphylococcus aureus strains have recently increased in number in our settings. We sought to evaluate the characteristics of these cases over a 43-month period. Data for all community-acquired staphylococcal infections caused by mupirocin-resistant strains were retrospectively reviewed. Genes encoding products producing high-level resistance (HLR) to mupirocin ( mupA ), fusidic acid resistance ( fusB ), resistance to macrolides and lincosamides ( ermC and ermA ), Panton-Valentine leukocidin (PVL) ( lukS/lukF -PV), exfoliative toxins ( eta and etb ), and fibronectin binding protein A ( fnbA ) were investigated by PCRs in 102 selected preserved strains. Genotyping was performed by SCC mec and agr typing, whereas clonality was determined by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). A total of 437 cases among 2,137 staphylococcal infections were recorded in 2013 to 2016; they were all SSTIs with the exception of 1 case of primary bacteremia. Impetigo was the predominant clinical entity (371 cases [84.9%]), followed by staphylococcal scalded skin syndrome (21 cases [4.8%]), and there were no abscesses. The number of infections detected annually increased during the study years. All except 3 isolates were methicillin susceptible. The rates of HLR to mupirocin and constitutive resistance to clindamycin were 99% and 20.1%, respectively. Among the 102 tested strains, 100 (98%) were mupA positive and 97 (95%) were fusB positive, 26/27 clindamycin-resistant strains (96.3%) were ermA positive, 83 strains (81.4%) were lukS/lukF positive, 95 (93%) carried both eta and etb genes, and 99 (97%) were fnbA positive. Genotyping of methicillin-sensitive S. aureus (MSSA) strains revealed that 96/99 (96.7%) belonged to one main pulsotype, pulsotype 1, classified as sequence type 121 (ST121). The emergence of a single MSSA clone (ST121) causing impetigo was documented. Resistance to

Kidneys and skin are seldom considered associated, but their relationship is more closer than generally believed. In some immunological diseases (SLE...) and genetic syndromes (tuberous sclerosis, Fabrys disease...) the cutaneous manifestations are integral parts of the clinical picture. In advanced uremia, besides the well-known itching skin lesions, calciphylaxis may appear, a typical example of cutaneous involvement secondary to the metabolic complications (calcium-phosphate imbalance) of the renal disease. Nephrogenic systemic fibrosis appears only in patients with renal failure and it has a very severe prognosis due to the systemic organ involvement. Moreover, there is a heterogeneous group of metabolic diseases, with renal involvement, that may be accompanied by skin lesions, either related to the disease itself or to its complications (diabetes mellitus, porphyrias). In systemic amyloidosis, fibrils may deposit even in dermis leading to different skin lesions. In some heroin abusers, in the presence of suppurative lesions in the sites of needle insertion, renal amyloidosis should be suspected, secondary to the chronic inflammation. Atheroembolic disease is nowadays frequently observed, as a consequence of the increasing number of invasive intravascular manoeuvres. Skin manifestations like livedo reticularis or the blue toe syndrome are the most typical signs, but often renal dysfunction is also present. In all these conditions, the skin lesion may be a first sign, a warning, that should arouse the suspicion of a more complex pathology, even with renal involvement. Being aware of this relationship is fundamental to accelerate the diagnostic process.

A case of Reiter's syndrome occurring in a young mate aged 20 years having extensive skin lesions of keratoderina blenoffhagica is presented along with a review of literature. Although urethritis was absent, other clinical and histopathological features of the cutaneous lesions led us to the diagnosis. The-possible relationship of postural psoriasis to Reiter's syndrome is discussed. Failure of the patient to respond satisfactorily to steroids, antibiotics etc, prompted the use of rnethotrexate in the case. The result was dramatic, as the patient completely recovered within ten days of starting treatment.

The Churg-Strauss syndrome, however, can affect any organ system, including the cardiovascular, gastrointestinal, renal, and central nervous systems
Cell junction protein armadillo repeat gene deleted in velo-cardio-facial syndrome is expressed in the skin and colocalizes with autoantibodies of patients affected by a new variant of endemic pemphigus foliaceus in Colombia.
Abreu-Velez, Ana Maria; Yi, Hong; Howard, Michael S
We previously described a new variant of endemic pemphigus foliaceus in El Bagre, Colombia, South America (El Bagre-EPF, or pemphigus Abreu-Manu). El Bagre-EPF differs from other types of EPF clinically, epidemiologically, immunologically and in its target antigens. We reported the presence of patient autoantibodies colocalizing with armadillo repeat gene deleted in velo-cardio-facial syndrome (ARVCF), a catenin cell junction protein colocalizing with El Bagre-EPF autoantibodies in the heart and within pilosebaceous units along their neurovascular supply routes. Here we investigate the presence of ARVCF in skin and its possibility as a cutaneous El Bagre-EPF antigen. We used a case-control study, testing sera of 45 patients and 45 controls via direct and indirect immunofluorescence (DIF/IIF), confocal microscopy, immunoelectron microscopy and immunoblotting for the presence of ARVCF and its relationship with El Bagre-EPF autoantibodies in the skin. We also immunoadsorbed samples with desmoglein 1 (Dsg1) ectodomain (El Bagre-EPF antigen) by incubating with the positive ARVCF samples from DIF and IIF. ARVCF was expressed in all the samples from the cases and controls. Immunoadsorption with Dsg1 on positive ARVCF immunofluorescence DIF/IIF cases showed that the immune response was present against non-desmoglein 1 antigen(s). Overall, 40/45 patients showed colocalization of their autoantibodies with ARVCF in the epidermis; no controls from the endemic area displayed colocalization. We demonstrate that ARVCF is expressed in many areas of human skin, and colocalizes with the majority of El Bagre-EPF autoantibodies as a putative antigen.

Full Text Available The Gorlin-Goltz syndrome (GGS (the nevoid basal cell carcinoma syndrome—NBCCS is a rare autosomal dominant syndrome caused due to mutations in the PTCH (patched gene found on chromosome arm 9q. The syndrome, characterized by increased predisposition to develop basal cell carcinoma and associated multiorgan anomalies, has a high level of penetrance and variable expressiveness. GGS is a multidisciplinary problem, early diagnosis of which allows introduction of secondary prophylaxis and following an appropriate treatment to delay the progress of the syndrome. The following report emphasizes the need for awareness of the diagnostic criteria of this syndrome in cases with no typical skin lesions.

During the last 50 years it has become clear that malignant tumours can induce symptoms unrelated to the mechanical effects of the primary tumour itself or its metastasis. Today, the name Paraneoplastic syndrome is given to those symptom complexes that may affect the blood cells, electrolytes, coagulation system, muscle, skin, nerve and the endocrine system. Endocrine symptoms were first recognised, and different hormones were isolated from the tumour tissue. However, tumour derived hormones ...
Full Text Available Partial albinism with immunodeficiency is a rare and fatal immunologic disorder characterized by pigmentary dilution and variable cellular immunodeficiency. It was initially described in 1978. Primary abnormalities included silvery grayish sheen to the hair, large pigment agglomerations in hair shafts and an abundance of mature melanosomes in melanocytes, with reduced pigmentation of adjacent keratinocytes. We describe a child with Griscelli syndrome who presented with hepatitis, pancytopenia and silvery hair. The diagnosis was confirmed by microscopic skin and hair examination.
A general survey of skin decontamination is given. The success of every decontamination treatments depends mainly on the speed, but also on the care, with which the action is taken. The best way to remove the skin contaminants is thorough washing under lukewarm running water with mild soap and a soft brush. This washing is to be repeated several times for a period of several minutes. If results are not satisfactory, light duty detergents and wetting agents available commercially may also be used. Some solutions which have proved useful are mentioned. The decontamination solutions are best used in the order given. When one has no satisfactory decontamination effect, the next one is to be used. If necessary, these agents must be used several times in the stated order as long as this does not involve too much strain for the skin. All the decontamination measures mentioned refer, of course, to intact healthy skin. After decontamination has been completed, the skin should be treated with a protective cream

Full Text Available Menopause is a physiological process typically occurring in the fifth decade of life. One of the most annoying oral symptoms in this age group is the burning mouth syndrome (BMS, which may be defined as an intraoral burning sensation occurring in the absence of identifiable oral lesion or laboratory findings. Pain in burning mouth syndrome may be described as burning, tender, tingling, hot, scalding, and numb sensation in the oral mucosa. Multiple oral sites may be involved, but the anterior two-third part and the tip of tongue are most commonly affected site. There is no definite etiology for BMS other than the precipitating causative factors, and it is still considered idiopathic. Various treatment options like use of benzodiazepine, anti-depressants, analgesics, capsaicin, alpha lipoic acids, and cognitive behavioral therapy are found to be effective, but definite treatment is still unknown. The present article discusses some of the recent concepts of etiopathogenesis of BMS as well as the role of pharmacotherapeutic management in this disorder.

Full Text Available Objective: Hand burns are common injuries. Children frequently sustain burn injuries, especially to their hands. Contractures are a common sequel of severe burns around joints. The prepuce, or foreskin, has been used as a skin graft for a number of indications. We conducted this study to evaluate the feasibility of utilising the preputial skin for the management of post-burn contractures of fingers in uncircumcised male children. Materials and Methods: Preputial skin was used for the coverage of released contractures of fingers in 12 patients aged 2-6 years. The aetiology of burns was "Kangri" burn in eight patients and scalding in four patients. Six patients had contracture in two fingers, four patients in one finger, and two patients had contractures in three fingers. Results: None of the patients had graft loss, and all the wounds healed within 2 weeks. All patients had complete release of contractures without any recurrence. Hyperpigmentation of the grafts was observed over a period of time, which was well accepted by the parents. Conclusions: Preputial skin can be used successfully for male children with mild-to-moderate contractures of 2-3 fingers for restoration of the hand function, minimal donor site morbidity.

This article reports on 14 cases of a trichorhinophalangeal syndrome in five successive generations. Besides the well-known characteristics of the TRPS the following symptoms observed in this family are new: Teething was considerably delayed, intelligence was reduced, and there were skin manifestations resembling eczema. Besides, struma colli and colitis ulcerosa were also observed. Subsequent observations have to clarify whether these symptoms are a facultative part of the TRPS pattern. The constant appearance of carriers of these characteristics during five generation points to dominant heredity.

Expanded access to DNA sequencing now fosters ready detection of site-specific human genome alterations whose actual significance requires in-depth functional study to rule in or out disease-causing mutations. This is a particular concern for genomic sequence differences in glycosyltransferases, whose implications are often difficult to assess. A recent whole-exome sequencing study identifies (c.229 C > T) in the GalNAc-4-ST1 glycosyltransferase (CHST8) as a disease-causing missense R77W mutation yielding the genodermatosis peeling skin syndrome (PSS) when homozygous. Cabral et al. (Genomics. 2012;99:202-208) cite this sequence change as reducing keratinocyte GalNAc-4-ST1 activity, thus decreasing glycosaminoglycan sulfation, as the mechanism for this blistering disorder. Such an identification could point toward potential clinical and/or prenatal diagnosis of a harmful medical condition. However, GalNAc-4-ST1 has minimal activity toward glycosaminoglycans, instead modifying terminal β1,4-linked GalNAc on N- and O-linked oligosaccharides on specific glycoproteins. We find expression, processing and catalytic activity of GalNAc-4-ST1 completely equivalent between wild type and (R77W) sulfotransferases. Moreover, keratinocytes have little or no GalNAc-4-ST1 mRNA, indicating that they do not express GalNAc-4-ST1. In addition, loss-of-function of GalNAc-4-ST1 primarily presents as reproductive system aberrations rather than skin effects. These findings, an allele frequency of 0.004357, and a 10-fold difference in prevalence of CHST8 (c.299 C > T, R77W) across different ethnic groups, suggest that this sequence represents a "passenger" distributed polymorphism, a simple sequence variant form of the enzyme having normal activity, rather than a "driver" disease-causing mutation that accounts for PSS. This study presents an example for guiding biomedical research initiatives, as well as medical and personal/family perspectives, regarding newly-identified genomic sequence

Lipidomics is the large-scale profiling and characterization of lipid species in a biological system using mass spectrometry. The skin barrier is mainly comprised of corneocytes and a lipid-enriched extracellular matrix. The major skin lipids are ceramides, cholesterol and free fatty acids (FFA). Lipid compositions are altered in inflammatory skin disorders with disrupted skin barrier such as atopic dermatitis (AD). Here we discuss some of the recent applications of lipidomics in human skin biology and in inflammatory skin diseases such as AD, psoriasis and Netherton syndrome. We also review applications of lipidomics in human skin equivalent and in pre-clinical animal models of skin diseases to gain insight into the pathogenesis of the skin disease. Expert commentary: Skin lipidomics analysis could be a fast, reliable and noninvasive tool to characterize the skin lipid profile and to monitor the progression of inflammatory skin diseases such as AD.

The transcription factor p63 is critically important for skin development and maintenance. Processes that require p63 include epidermal lineage commitment, epidermal differentiation, cell adhesion, and basement membrane formation. Not surprisingly, alterations in the p63 pathway underlie a subset of ectodermal dysplasias, developmental syndromes in which the skin and skin appendages do not develop normally. This review summarizes the current understanding of the role of p63 in normal development and ectodermal dysplasias. PMID:20445549

Burns can cause tremendous economic problems associated with irreparable harm to patients and their families. To characterize marine collagen peptides (MCPs) from the skin of Nile tilapia ( Oreochromis niloticus ), molecular weight distribution and amino acid composition of MCPs were determined, and Fourier transform infrared spectroscopy (FTIR) was used to analyze the chemical structure. Meanwhile, to evaluate the wound healing activity, in vitro and in vivo experiments were carried out. The results showed that MCPs prepared from the skin of Nile tilapia by composite enzymatic hydrolysis were composed of polypeptides with different molecular weights and the contents of polypeptides with molecular weights of less than 5 kDa accounted for 99.14%. From the amino acid composition, the majority of residues, accounting for over 58% of the total residues in MCPs, were hydrophilic. FTIR indicated that the main molecular conformations inside MCPs were random coil. In vitro scratch assay showed that there were significant effects on the scratch closure by the treatment of MCPs with the concentration of 50.0 μg/mL. In the experiments of deep partial-thickness scald wound in rabbits, MCPs could enhance the process of wound healing. Therefore, MCPs from the skin of Nile tilapia ( O. niloticus ) have promising applications in wound care.

Generalized peeling skin disease is an autosomal-recessive ichthyosiform erythroderma characterized by lifelong patchy peeling of the skin. After genome-wide linkage analysis, we have identified a homozygous nonsense mutation in CDSN in a large consanguineous family with generalized peeling skin, pruritus, and food allergies, which leads to a complete loss of corneodesmosin. In contrast to hypotrichosis simplex, which can be associated with specific dominant CDSN mutations, peeling skin disease is characterized by a complete loss of CDSN expression. The skin phenotype is consistent with a recent murine Cdsn knockout model. Using three-dimensional human skin models, we demonstrate that lack of corneodesmosin causes an epidermal barrier defect supposed to account for the predisposition to atopic diseases, and we confirm the role of corneodesmosin as a decisive epidermal adhesion molecule. Therefore, peeling skin disease will represent a new model disorder for atopic diseases, similarly to Netherton syndrome and ichthyosis vulgaris in the recent past.

Constitutional mismatch repair deficiency (CMMR-D) syndrome is characterised by a significantly increased risk for developing cancer in childhood. It arises when both parents have a mutation in the same mismatch repair gene and pass it on to their child. An 8-year-old girl was diagnosed with CMMR-D syndrome after she developed a brain tumour at the age of 4 and a T-cell non-Hodgkin lymphoma at the age of 6. She had multiple hyperpigmented skin lesions and died of myelodysplastic syndrome at the age of 11. In children with cancer CMMR-D syndrome can be recognized particularly if there are multiple primary malignancies and skin hyperpigmentations and hypopigmentations. The parents of these children are at high risk for colorectal and endometrial cancer (Lynch syndrome), amongst others.

The hypertrophic scar is a medical difficulty of humans, which has caused great pain to patients. Here, we investigated the inhibitory effect of miR-29b on scar formation. The scalded model was established in mice and miR-29b mimics or a negative control was subcutaneously injected into the injury skin. Then various molecular biological experiments were performed to assess the effect of miR-29b on scar formation. According to our present study, first, the results demonstrated that miR-29b was down-regulated in thermal injury tissue and miR-29b treatment could promote wound healing, inhibit scar formation, and alleviate histopathological morphologic alteration in scald tissues. Additionally, miR-29b treatment suppressed collagen deposition and fibrotic gene expression in scar tissues. Finally, we found that miR-29b treatment inhibited the TGF-β1/Smad/CTGF signaling pathway. Taken together, our data suggest that miR-29b treatment has an inhibitory effect against scar formation via inhibition of the TGF-β1/Smad/CTGF signaling pathway and may provide a potential molecular basis for future treatments for hypertrophic scars.

Oily skin (seborrhea) is a common cosmetic problem that occurs when oversized sebaceous glands produce excessive amounts of sebum giving the appearance of shiny and greasy skin. This paper overviews the main concepts of sebaceous gland anatomy and physiology, including the biosynthesis, storage and release of sebum, as well as its relationship to skin hydration and water barrier function. We also address how skin oiliness may vary according to diet, age, gender, ethnicity and hot humid climates. The deeper understanding of this skin type provides the opportunity to better guide patients regarding skin care and also assist in the development of sebosuppressive agents. Copyright © 2012 S.

Full Text Available Cessation of normal skin cleansing seen in geriatric or self-neglected patients can cause accumulation of keratinous crusts on the skin. In the extreme end of this spectrum is a condition known as Diogenes syndrome (DS. These patients may have psychiatric disorders like paranoid disorders, mood affection, or temporofrontal dementia. Subjects are mainly the elderly but few cases in younger age group of patients have also been reported. Lesions of DS are usually found over upper central chest, back, and groin. In the young, lesions are mainly found over scalp, face, or arms. Absence of normal skin cleaning causes keratin and dirty debris to accumulate and with time form a thick shell. These debris can be secondarily infected by bacteria, fungus, and so forth. These skin lesions are not usually seen in individual with proper hygiene. We report a case of Diogenes syndrome in a 34-year-old young male patient who had associated schizophrenia.

This study assessed the effect of early vs delayed postburn wound excision and skin grafting on the in vivo neutrophil delivery to a delayed-type hypersensitivity (DTH) reaction and a bacterial skin lesion (BSL). Male Lewis rats were presensitized to keyhole-limpet hemocyanin. Group 1 comprised sham controls. Groups 2 through 4 were given a 30% 3 degrees scald burn, but the burn wounds were excised, and skin was grafted on days 1, 3, and 7, respectively, after the burn. Group 5 comprised burn controls. Twelve days after burn trauma, all rats were injected at different intervals (during a 24-hour period) with a trio of intradermal injections of keyhole-limpet hemocyanin, Staphylococcus aureus 502A, and saline at different sites. In vivo neutrophil delivery to these dermal lesions was determined by injecting indium in 111 oxyquinoline-labeled neutrophils isolated from similarly treated groups of rats. Neutrophil delivery to DTH and BSL lesions was restored to normal by excision and skin grafting of the burn wound one day after burn trauma. Waiting three days after burn trauma to excise and skin graft the wound partially, but not completely, restored the in vivo neutrophil delivery to DTH and BSL lesions. Waiting one week to excise and skin graft a burn wound resulted in no improvement in neutrophil delivery to DTH and BSL dermal lesions. It was concluded that burn wound excision and skin grafting immediately after burn trauma restored in vivo neutrophil delivery to a BSL and DTH dermal lesion. This may, in part, explain the beneficial effect of early aggressive burn wound debridement in patients with burn injuries
Full Text Available Context Preclinical and clinical research has shown that stem cell therapy is a promising therapeutic option for many diseases. This article describes skin stem cells sources and their therapeutic applications. Evidence Acquisition Compared with conventional methods, cell therapy reduces the surgical burden for patients because it is simple and less time-consuming. Skin cell therapy has been developed for variety of diseases. By isolation of the skin stem cell from the niche, in vitro expansion and transplantation of cells offers a surprising healing capacity profile. Results Stem cells located in skin cells have shown interesting properties such as plasticity, transdifferentiation, and specificity. Mesenchymal cells of the dermis, hypodermis, and other sources are currently being investigated to promote regeneration. Conclusions Because skin stem cells are highly accessible from autologous sources and their immunological profile is unique, they are ideal for therapeutic approaches. Optimization of administrative routes requires more investigation own to the lack of a standard protocol.

The nervous, immune, endocrine and integumentary systems are closely related and interact in a number of normal and pathological conditions. Nervous system mediators may bring about direct changes to the skin or may induce the release of immunological or hormonal mediators that cause pathological changes to the skin. This article reviews the psychological mechanisms involved in the development of skin diseases.
The human skin is composed of several layers, each with an unique structure and function. Knowledge about the mechanical behavior of these skin layers is important for clinical and cosmetic research, such as the development of personal care products and the understanding of skin diseases. Until

Lynch Syndrome, also known as Hereditary Non-Polyposis Colorectal Cancer (HNPCC), is a hereditary condition that increases an individual’s risk of developing a constellation of cancers. These most commonly arise in the colon, but also involve other solid organs such as the endometrium and ovaries in women, the stomach, brain and the skin. Ireland’s small population offers an opportunity to identify all those with Lynch Syndrome (LS) in the country, which would represent a powerful preventive opportunity to meaningfully impact on the incidence of cancer in Ireland.

Full Text Available A case of Reiter′s syndrome occurring in a young mate aged 20 years having extensive skin lesions of keratoderina blenoffhagica is presented along with a review of literature. Although urethritis was absent, other clinical and histopathological features of the cutaneous lesions led us to the diagnosis. The-possible relationship of postural psoriasis to Reiter′s syndrome is discussed. Failure of the patient to respond satisfactorily to steroids, antibiotics etc, prompted the use of rnethotrexate in the case. The result was dramatic, as the patient completely recovered within ten days of starting treatment.

Full Text Available Human skin is a complex organ in its structure. Numerous functions of the skin may be impaired in its pathology. Anatomical and physiological characteristics of the skin in children predispose to common diseases of the skin. Diaper dermatitis is one of the most common skin diseases during infancy and childhood. Diapered skin is exposed to friction and excessive hydration, has a higher pH than nondiapered skin, and is repeatedly soiled with feces that contains enzymes with high irritation potential for the skin. Diaper dermatitis may vary in clinical severity and course. Therapeutically, frequent diaper changes and adequate skin care are most important. Appropriate skin care can help to prevent the occurrence of diaper dermatitis and to speed up the healing of affected skin. This includes frequent diaper changes and aeration, gentle cleansing, and the use of a barrier cream. For the treatment of diaper dermatitis agents selected depending on the presence and severity of complications. For prevention and treatment of uncomplicated diaper dermatitis effective means of containing dexpantenol.

Nutrition has long been associated with skin health, including all of its possible aspects from beauty to its integrity and even the aging process. Multiple pathways within skin biology are associated with the onset and clinical course of various common skin diseases, such as acne, atopic dermatitis, aging, or even photoprotection. These conditions have been shown to be critically affected by nutritional patterns and dietary interventions where well-documented studies have demonstrated beneficial effects of essential nutrients on impaired skin structural and functional integrity and have restored skin appearance and health. Although the subject could be vast, the intention of this review is to provide the most relevant and the most well-documented information on the role of nutrition in common skin conditions and its impact on skin biology.

Gene knockout studies unexpectedly reveal a pivotal role for IκB kinase alpha (IKKα) in mouse embryonic skin development. Skin carcinogenesis experiments show that Ikkα heterozygous mice are highly susceptible to chemical carcinogen or ultraviolet B light (UVB) induced benign and malignant skin tumors in comparison to wild-type mice. IKKα deletion mediated by keratin 5 (K5).Cre or K15.Cre in keratinocytes induces epidermal hyperplasia and spontaneous skin squamous cell carcinomas (SCCs) in Ikkα floxed mice. On the other hand, transgenic mice overexpressing IKKα in the epidermis, under the control of a truncated loricrin promoter or K5 promoter, develop normal skin and show no defects in the formation of the epidermis and other epithelial organs, and the transgenic IKKα represses chemical carcinogen or UVB induced skin carcinogenesis. Moreover, IKKα deletion mediated by a mutation, which generates a stop codon in the Ikkα gene, has been reported in a human autosomal recessive lethal syndrome. Downregulated IKKα and Ikkα mutations and deletions are found in human skin SCCs. The collective evidence not only highlights the importance of IKKα in skin development, maintaining skin homeostasis, and preventing skin carcinogenesis, but also demonstrates that mouse models are extremely valuable tools for revealing the mechanisms underlying these biological events, leading our studies from bench side to bedside.

The objective of this study is to develop and present a simple procedure for evaluating the temperature and exposure-time conditions that lead to causation of a deep-partial thickness burn and the effect that the immediate post-burn thermal environment can have on the process. A computational model has been designed and applied to predict the time required for skin burns to reach a deep-partial thickness level of injury. The model includes multiple tissue layers including the epidermis, dermis, hypodermis, and subcutaneous tissue. Simulated exposure temperatures ranged from 62.8 to 87.8°C (145-190°F). Two scenarios were investigated. The first and worst case scenario was a direct exposure to water (characterized by a large convection coefficient) with the clothing left on the skin following the exposure. A second case consisted of a scald insult followed immediately by the skin being washed with cool water (20°C). For both cases, an Arrhenius injury model was applied whereby the extent and depth of injury were calculated and compared for the different post-burn treatments. In addition, injury values were compared with experiment data from the literature to assess verification of the numerical methodology. It was found that the clinical observations of injury extent agreed with the calculated values. Furthermore, inundation with cool water decreased skin temperatures more quickly than the clothing insulating case and led to a modest decrease in the burn extent.

Objective: To investigate the dynamic expression of apoptosis-related genes Bcl-2, Bax and P53 in acute radiation-induced skin ulcers, and to explore the underlying mechanism involved in retarded healing of the ulcer. Methods: Fifty-four female SD rats were divided into 3 groups. The model of acute radiation-induced skin injury, in rats was replicated with 45 Gy electron accelerator β-ray to the skin as radiation group (n=24); the model of deep second degree scald in rats was established as burn group (n=24); 6 normal rats were served as normal control group. From different periods skin wounds, the expression of Bcl-2, Bax and P53 were respectively assessed by means of immunohistochemical technique and. apoptosis was observed by TUNEL assay. Results: (1) The result of the TUNEL manifested that the integral absorbance (IA) of the radiation group was much higher than that of the control group. There is statistical significance between the two groups (P<0.05). (2) 0, 1, 2, 3 weeks after wound emerging, the Bax and P53 integral absorbance (IA) in radiation group was much higher than that of the control group. The Bcl-2 integral absorbance (IA) in bum group was much higher than that of the radiation group. There is statistical significance between the two groups (P<0.05). Conclusions: It was shown that apoptosis of β radiation manifested three typical characteristics, namely early occurrence, high frequency and delayed disappearance after radiation, which might explain the delayed wound healing caused by β radiation.

Ectodermal dysplasia (ED) syndrome comprises a large, heterogeneous group of inherited disorders that are defined by primary defects in the development of 2 or more tissues derived from the embryonic ectoderm. The tissues primarily involved are the skin and its appendages (including hair follicles, eccrine glands, sebaceous glands, nails) and teeth. The clinical features include sparse hair, abnormal or missing teeth, and an inability to sweat due to lack of sweat glands. One such case report of ectodermal dysplasia is presented here.

Antiphospholipid syndrome (APS) is an autoimmune disease characterized by antiphospholipid antibodies (aPL) associated with thrombosis and/or pregnancy morbidity. Most APS events are directly related to thrombotic events, which may affect small, medium or large vessels. Other clinical features like thrombocytopenia, nephropathy, cardiac valve disease, cognitive dysfunction and skin ulcers (called non-criteria manifestations) add significant morbidity to this syndrome and represent clinical situations that are challenging. APS was initially described in patients with systemic lupus erythematosus (SLE) but it can occur in patients without any other autoimmune disease. Despite the autoimmune nature of this syndrome, APS treatment is still based on anticoagulation and antiplatelet therapy.

Further to the reecommendations for determining the surface contamination of the skin and estimating the radiation exposure of the skin after contamination (SAAS-Mitt--89-16), measures for skin decontamination are recommended. They are necessary if (1) after simple decontamination by means of water, soap and brush without damaging the skin the surface contamination limits are exceeded and the radiation exposure to be expected for the undamaged healthy skin is estimated as to high, and if (2) a wound is contaminated. To remove skin contaminations, in general universally applicable, non-aggressive decontamination means and methods are sufficient. In special cases, nuclide-specific decontamination is required taking into account the properties of the radioactive substance
Full Text Available Patients suffering from endocrine disorders often present a wide profile of skin lesions. In hyperthyroidism we observe hair loss, lower leg myxedema and onycholysis or, in the case of hormone deficiency, generalized swelling of the skin, which becomes cold and pale. Primary hyperparathyroidism is revealed by pruritus, presence of chronic urticaria or deposition of amorphous calcium salts. In hypoparathyroidism, the skin is dry while the nails become very brittle. Skin lesions in diabetes include necrobiosis lipoidica, granuloma annulare, scleroderma-like diabetic edema and acanthosis nigricans. Overactive pituitary gland is often manifested as acromegaly with hypertrophy of soft tissue thickening and hypertrichosis. The skin in the early stages of hypopituitarism feels swollen, is pale yellow and oily, and finally becomes alabaster and dry. The characteristic features of Cushing syndrome are central obesity, lunar face, buffalo hump, and striae. In Addison’s disease we observe hyperpigmentation. Hyperandrogenism in women leads to acne, hirsutism and virilization.

Severely burned patients need definitive and efficient wound coverage. The outcome of massive burns has improved with cultured epithelial auto-grafts (CEA). In spite of its fragility, percentage of success, cost of treatment and long-term tendency to contracture, this surgical technique has been developed in some burn centres. The first improvements involved combining CEA and dermis-like substitutes. Cultured skin substitutes provide faster skin closure and satisfying functional results. These methods have been used successfully in massive burns. A second improvement was to enable skin regeneration by using epidermal stem cells. Stem cells can differentiate into keratinocytes, to promote wound repair and to regenerate skin appendages. Human mesenchymal stem cells foster wound healing and were used in cutaneous radiation syndrome. Skin regeneration and tissue engineering methods remain a complex challenge and offer the possibility of new treatment for injured and burned patients. (authors)

The human skin is a well-organized organ bearing different types of cells in a well-structured interference to each other including epidermal and follicular keratinocytes, sebocytes, melanocytes, dermal papilla cells and fibroblasts, endothelial cells, sweat gland cells as well as nerves. Several hormones act on different cell types of the skin, while it is also considered an endocrine organ secreting hormones that act at several sites of the organism. GH receptors are found in almost all cell types forming the skin, while IGF-1 receptors' expression is restricted to the epidermal keratinocytes. Both Growth Hormone (GH) excess, as in the case of Acromegaly in adults, or Gigantism in growing children, and GH deficiency states lead to skin manifestations. In case of GH excess the main dermatological findings are skin thickening, coarsening of facial features, acrochordons, puffy hands and feet, oily skin and hyperhidrosis, while GH deficiency, on the contrary, is characterized by thin, dry skin and disorder of normal sweating. Moreover, special disorders associated with GH excess may have specific characteristics, as is the case of café-au-lait spots in Neurofibromatosis, or big café-au-lait skin hyperpigmented regions with irregular margins, as is the case in McCune-Albright syndrome. Meticulous examination of the skin may therefore contribute to the final diagnosis in cases of GH-induced disorders.

The research is done to provide appropriate detection technique for skin tumor detection. The work is done by using the image processing toolbox of MATLAB. Skin tumors are unwanted skin growth with different causes and varying extent of malignant cells. It is a syndrome in which skin cells mislay the ability to divide and grow normally. Early detection of tumor is the most important factor affecting the endurance of a patient. Studying the pattern of the skin cells is the fundamental problem in medical image analysis. The study of skin tumor has been of great interest to the researchers. DIP (Digital Image Processing) allows the use of much more complex algorithms for image processing, and hence, can offer both more sophisticated performance at simple task, and the implementation of methods which would be impossibly by analog means. It allows much wider range of algorithms to be applied to the input data and can avoid problems such as build up of noise and signal distortion during processing. The study shows that few works has been done on cellular scale for the images of skin. This research allows few checks for the early detection of skin tumor using microscopic images after testing and observing various algorithms. After analytical evaluation the result has been observed that the proposed checks are time efficient techniques and appropriate for the tumor detection. The algorithm applied provides promising results in lesser time with accuracy. The GUI (Graphical User Interface) that is generated for the algorithm makes the system user friendly. (author)

It is estimated that total sun exposure occurs non-intentionally in three quarters of our lifetimes. Our skin is exposed to majority of UV radiation during outdoor activities, e.g. walking, practicing sports, running, hiking, etc. and not when we are intentionally exposed to the sun on the beach. We rarely use sunscreens during those activities, or at least not as much and as regular as we should and are commonly prone to acute and chronic sun damage of the skin. The only protection of our skin is endogenous (synthesis of melanin and enzymatic antioxidants) and exogenous (antioxidants, which we consume from the food, like vitamins A, C, E, etc.). UV-induced photoaging of the skin becomes clinically evident with age, when endogenous antioxidative mechanisms and repair processes are not effective any more and actinic damage to the skin prevails. At this point it would be reasonable to ingest additional antioxidants and/or to apply them on the skin in topical preparations. We review endogenous and exogenous skin protection with antioxidants.

Skin cancer due to occupation is more common than is generally recognized, although it is difficult to obtain an accurate estimate of its prevalence. Over the past two centuries, occupational skin cancers have particularly been due to industrial exposure of men (it seems more so than women) to chemical carcinogens such as polycyclic hydrocarbons (e.g. from coal tar products) or to arsenic. Industrial processes have improved in most Western countries to limit this type of exposure, but those with outdoor occupations are still exposed to solar ultraviolet irradiation without this being widely recognized as an industrial hazard. Ionizing radiation such as X-rays can also cause skin cancer. Occupational skin cancers often resemble skin tumours found in non-occupational subjects, e.g. basal cell carcinoma, squamous cell carcinoma and malignant melanoma, but some pre-malignant lesions can be more specific and point to an occupational origin, e.g. tar keratoses or arsenical keratoses. An uncommon but well-recognized cause of occupational skin cancer is that which results from scar formation following an industrial burn. In the future it will be necessary to focus on preventative measures, e.g. for outdoor workers, the need to cover up in the sun and use sun protective creams and a campaign for earlier recognition of skin cancers, which are usually curable if treated in their early stages.

Full Text Available Skin picking disorder is not a dermatological disorder and it is a table characterized with picking skin excessively and repetitively, leading to damage in skin tissue. Unlike normal picking behaviour, psychogenic skin picking is repetitive and it can lead to severe damage in the skin and even complications which constitute vital danger. While some patients define frequent but short lasting picking attacks, others define rarer attacks which last a few hours. Skin picking disorder, which is not included in the classification systems up to DSM-5 as a separate diagnosis category, is included as an independent diagnosis in Obsessive Compulsive Disorder and Associated Disorders category in DSM-5. In case reports, open label studies and double blind studies selective serotonin reuptake inhibitors are shown to be effective in the treatment of skin picking disorder. Mostly, cognitive-behaviourial techniques are used and have been proven to be useful in psychotherapy. Habit reversal is one of the behaviourial techniques which are frequently applied, give positive results in which well-being state can be maintained.

Ultrasound skin tightening is a noninvasive, nonablative method that allows for energy deposition into the deep dermal and subcutaneous tissue while avoiding epidermal heating. Ultrasound coagulation is confined to arrays of 1-mm(3) zones that include the superficial musculoaponeurotic system and connective tissue. This technology gained approval from the Food and Drug Administration as the first energy-based skin "lifting" device, specifically for lifting lax tissue on the neck, submentum, and eyebrows. Ultrasound has the unique advantage of direct visualization of treated structures during treatment. Ultrasound is a safe and efficacious treatment for mild skin tightening and lifting.

Skin, hair, and nails are visible to self and others, and touchable by self and others. The skin is a major sensory organ. Skin also expresses emotions detectable by others through pallor, coldness, "goose bumps", redness, warmth, or sweating. Spiritual and religious significances of skin are revealed through how much of the skin has been and continues to be covered with what types of coverings, scalp and beard hair cutting, shaving and styling, skin, nail, and hair coloring and decorating, tattooing, and intentional scarring of skin. Persons with visible skin disorders have often been stigmatized or even treated as outcasts. Shamans and other spiritual and religious healers have brought about healing of skin disorders through spiritual means. Spiritual and religious interactions with various skin disorders such as psoriasis, leprosy, and vitiligo are discussed. Religious aspects of skin and skin diseases are evaluated for several major religions, with a special focus on Judaism, both conventional and kabbalistic.

Altered skin integrity increases the chance of infection, impaired mobility, and decreased function and may result in the loss of limb or, sometimes, life. Skin is affected by both intrinsic and extrinsic factors. Intrinsic factors can include altered nutritional status, vascular disease issues, and diabetes. Extrinsic factors include falls, accidents, pressure, immobility, and surgical procedures. Ensuring skin integrity in the elderly requires a team approach and includes the individual, caregivers, and clinicians. The twenty-first century clinician has several online, evidence-based tools to assist with optimal treatment plans. Understanding best practices in addressing skin integrity issues can promote positive outcomes with the elderly. Copyright © 2017 Elsevier Inc. All rights reserved.

The current trend of burn wound care has shifted to more holistic approach of improvement in the long-term form and function of the healed burn wounds and quality of life. Autologous split or full-thickness skin graft are the best definitive burn wound coverage, but it is constrained by the limited available sources, especially in major burns. Donor site morbidities in term of additional wounds and scarring are also of concern of the autograft application. This has demanded the emergence of various skin substitutes in the management of acute burn injury as well as post burn reconstructions. This paper reviews currently available skin substitutes, produced in not for-profit skin banks as well as commercially available. They are divided according to type of material included, as biological, biosynthetic and synthetic and named respectively.

Full Text Available Drug rash with eosinophilia and systemic symptoms (DRESS syndrome reflects a serious hypersensitivity reaction to drugs, and is characterized by skin rash, fever, lymph node enlargement, and internal organ involvement. So far, numerous drugs such as sulfonamides, phenobarbital, sulfasalazine, carbamazepine, and phenytoin have been reported to cause DRESS syndrome. We report a case of a 10-year-old girl who developed clinical manifestations of fever, rash, lymphadenopathy, hypereosinophilia, and visceral involvement (hepatitis and pneumonitis after taking phenobarbital for seizures, with subsequent development of sepsis, acute respiratory distress syndrome (ARDS and spontaneous air leak syndrome (pnemothorax and pneumomediastinum. She was put on steroids and various antibiotics and was ventilated, but ultimately succumbed to sepsis and pulmonary complications.

Advantages and disadvantages of stressed skin panels, also known as structural insulated panels (SIPs), are discussed as material and labour-saving alternatives to traditional stick framing. Stressed skin panels are manufactured 'sandwich' assemblies with a rigid insulating polystyrene foam core, whose interior and exterior surfaces are bonded into panels. The skins distribute and carry the structural loading while the bonded foam core provides insulation and keeps the two skins aligned. Since there are fewer framing members, there is little thermal bridging and the R-value remains high. SIPs are usually manufactured in four feet by eight feet panels, although some manufacturers can produce panels up to eight feet by forty feet. SIPs are resource efficient as they use less wood than conventional framing (about 25 per cent less); can structurally cover large spans, requiring less supplementary framing. Use of SIPs eliminate the need for headers over small openings; provide the ability to nail anywhere; create less scrap and waste; lessen vulnerability to unfavourable weather and other job-site hazards, can reduce delays, and often can produce significant savings in material and labour costs. Limitations include the more complex approaches to plumbing and electrical systems, although this can be minimized by designers by incorporating much of the plumbing and electrical work on interior (non-panel) walls. Most stressed skin panels require one-half inch interior gypsum drywall. If become wet, stressed skin panels take a long time to dry out and may harbour mold growth. Larger stressed-skin panels used in floors and roofs, may require cranes or other machinery for handling because of their weight. Although not without some environmental impact, overall, stressed skin panels are judged to be a resource-efficient building technology with significant energy-efficiency benefits and distinct advantages over stick framing. 3 photos.

To clarify the multiracial occurrence of Waardenburg syndrome, we present a case series and literature review. A computerized review of the English-language literature was conducted to assess the distribution of reported occurrences of Waardenburg syndrome in populations around the world. We detail the clinical features of 2 family cohorts: one of Western European origin and the other from South Asia. A computerized literature review found sporadic cases of the syndrome in many ethnic groups, including Japanese, Taiwanese, and Middle Eastern families. The highest reported incidence is among Kenyan Africans. Waardenburg syndrome accounts for between 2% and 5% of cases of congenital deafness. It was first described in Northern European cohorts and is widely identified in fair-skinned populations. We hope to raise awareness of the worldwide distribution of this important cause of hearing loss.

Full Text Available Ehlers-Danlos syndrome (EDS is a generalized disorder of one element of connective tissue manifesting clinically by fragility and hyperelasticity of the skin and joint laxity. It is a hereditary disorder, the inheritance being usually autosomal dominant with low penetrance. Autosomal recessive and X-linked recessive varieties are also known. First described by Hippocrates in 4 th century B.C., the various clinical types with variable penetrance have been described lately. The number of cases EDS reported in the literature is very meagre. With the available information only about six publications of classic EDS in siblings had been reported in Indian literature.

This article reports on 14 cases of a trichorhinophalangeal syndrome in five successive generations. Besides the well-known characteristics of the TRPS the following symptoms observed in this family are new: Teething was considerably delayed, intelligence was reduced, and there were skin manifestations resembling eczema. Besides, struma colli and colitis ulcerosa were also observed. Subsequent observations have to clarify whether these symptoms are a facultative part of the TRPS pattern. The constant appearance of carriers of these characteristics during five generation points to dominant heredity. (orig.) [de

Malignant melanoma is often lethal, and its incidence in the United States has increased rapidly over the past 2 decades. Nonmelanoma skin cancer is seldom lethal, but, if advanced, can cause severe disfigurement and morbidity. Early detection and treatment of melanoma might reduce mortality, while early detection and treatment of nonmelanoma skin cancer might prevent major disfigurement and to a lesser extent prevent mortality. Current recommendations from professional societies regarding screening for skin cancer vary. To examine published data on the effectiveness of routine screening for skin cancer by a primary care provider, as part of an assessment for the U.S. Preventive Services Task Force. We searched the MEDLINE database for papers published between 1994 and June 1999, using search terms for screening, physical examination, morbidity, and skin neoplasms. For information on accuracy of screening tests, we used the search terms sensitivity and specificity. We identified the most important studies from before 1994 from the Guide to Clinical Preventive Services, second edition, and from high-quality reviews. We used reference lists and expert recommendations to locate additional articles. Two reviewers independently reviewed a subset of 500 abstracts. Once consistency was established, the remainder were reviewed by one reviewer. We included studies if they contained data on yield of screening, screening tests, risk factors, risk assessment, effectiveness of early detection, or cost effectiveness. We abstracted the following descriptive information from full-text published studies of screening and recorded it in an electronic database: type of screening study, study design, setting, population, patient recruitment, screening test description, examiner, advertising targeted at high-risk groups or not targeted, reported risk factors of participants, and procedure for referrals. We also abstracted the yield of screening data including probabilities and numbers

Two siblings (male, 29 years, and female, 13 years) with the rare autosomal recessive osteoporosis pseudoglioma syndrome are reported in detail. All essential signs and symptoms of the full clinical picture were present and are documented by impressive X-ray pictures. Some aspects of our patients are compared with relevant findings of previous reports. Collagen studies (skin biopsies) failed to reveal any significant disorder of the main collagen types composition. Striking similarities with established genetic disorders of collagen (like the osteogenesis imperfecta group and the Ehlers-Danlos syndrome) suggest, however, that the OPS could be a primary collagen disorder. Genetic counselling and devoted socio-medical care for these handicapped children is presently the only help which can be offered. (orig.)

Waardenburg syndrome (WS) is a rare disease characterized by a sensorineural hearing loss and pigment anomalies of the iris, skin and hair due to mutations in PAX3. WS can be subdivided into four groups according to major and minor clinical signs. We report the case of a 2 1/2-year-old coloured patient who presented in our department of paediatric ophthalmology for a syndrome search. The patient presented with hearing loss, brilliant blue iris colour and dystopia canthorum. The patient was slightly hypermetropic. Visual acuity was within normal limits according to the Cardiff acuity test. The ocular fundus examination revealed no abnormalities. According to the major and minor criteria defined by the Waardenburg consortium our patient showed the major criteria of WS1, i.e. hearing loss, hypopigmentation of the pigment epithelium of the iris and dystopic canthi. Diagnosis of WS is usually based on the clinical presentation. An additional molecular genetic analysis is possible.

Waardenburg syndrome is a rare form of neurocristopathy. It is a disorder in the development of neural crest cells, caused by an altered cellular migration during the embryonic phase. That alteration causes an association of different abnormalities such as pigmentary disturbances of the hair, iris, skin, stria vascularis of the cochlea, dystopia canthorum and sensorineural hearing loss. We report a case of a 14-year-old Romanian male, with a family history of Waardenburg syndrome (mother) and Usher syndrome (father - congenitally sensorineural hearing loss and retinal degeneration). The case particularities are: the correlation between malocclusion and Waardenburg syndrome due to hypoplastic alae nasi and also factors that produced hearing loss, which could be Waardenburg syndrome, Usher syndrome or the presence of the connexin 26 (W24X) gene mutation.

Ichthyosis refers to a group of skin diseases characterized by abnormal keratinization of the epidermis, resulting in dryness, roughness and scale of the skin. A girl with ichthyosis, who presented with skin ulcers and infection of the right dorsal foot, was admitted to our department. An autologous razor-thin skin grafting procedure was performed to repair the skin ulcers after debridement and vacuum sealing drain. After 8 months of follow-up, both the donor and recipient site healed well and there were no newly formed ulcers or infections. Although the skin quality of ichthyosis is poor, the lesion area can still be used as donor or recipient cite.

Gorlin-Goltz syndrome is a rare multisystemic disease inherited in an autosomal dominant pattern. It is characterized by numerous basal cell carcinoma of the skin, jaw cysts, and skeletal anomalies such as frontal bossing, vertebral anomalies, palmoplantar pits, and falx cerebri calcification. There is a tendency to tumors including medullablastoma, fibroma, rabdomyoma, leiomyosarcoma etc.. The diagnosis is based on major and minor clinical and radiologic criteria. Early diagnosis and treatment are of utmost importance in reducing the severity of long-term sequelae of this syndrome. In this article, we present a 15-year-old boy who was admitted to our clinic with brown-black papules and plaques on his scalp and was thought to have Gorlin-Goltz syndrome. He had a history of medulloblastoma that was treated with surgical resection followed by cranial radiotherapy and unilateral retinoblastoma. We present this case, because association of Gorlin-Goltz syndrome and retinoblastoma has not been described previously in the literature and we aimed to draw attention to radiation-induced basal cell carcinomas.

Full Text Available Poland’s syndrome is a rare congenital condition classically characterized by partial or complete absence of chest muscles on one side of the body and usually webbing of the fingers of the hand on the same side. There may also be rib (aplasia or hypoplasia and chest bone abnormalities, which may be noticeable due to less fat under the skin. Breast and nipple abnormalities may also occur, and underarm hair is sometimes sparse or abnormally placed. In most cases, the abnormalities in the chest area do not cause health problems or affect movement. Poland’s syndrome most often affects the right side of the body and occurs more frequently in males than in females. The etiology is unknown; however, interruption of the embryonic blood supply to the arteries that lie under the collarbone (subclavian arteries is the prevailing theory. There are many methods of operative correction because of the polymorphic clinical features of this syndrome. We gathered data on the etiology, pathogenesis, and clinical presentation of Poland’s syndrome and reviewed the existing surgical treatment options.

Tobacco smoking is a serious and preventable health hazard that can cause or exacerbate a number of diseases and shorten life expectancy, but the role of smoking as an etiologic factor in the development of skin disease is largely unknown. Although epidemiological evidence is sparse, findings...... suggest that tobacco smoking is a contributing factor in systemic lupus erythematosus, psoriasis, palmoplantar pustulosis, cutaneous squamous cell carcinoma, hidradenitis suppurativa, and genital warts. In contrast, smoking may confer some protective effects and mitigate other skin diseases, notably...... pemphigus vulgaris, pyoderma gangrenosum, aphthous ulcers, and Behçet's disease. Various degenerative dermatologic conditions are also impacted by smoking, such as skin wrinkling and dysregulated wound healing, which can result in post-surgical complications and delayed or even arrested healing of chronic...

Fabricating a turbine component (50) by casting a core structure (30), forming an array of pits (24) in an outer surface (32) of the core structure, depositing a transient liquid phase (TLP) material (40) on the outer surface of the core structure, the TLP containing a melting-point depressant, depositing a skin (42) on the outer surface of the core structure over the TLP material, and heating the assembly, thus forming both a diffusion bond and a mechanical interlock between the skin and the core structure. The heating diffuses the melting-point depressant away from the interface. Subsurface cooling channels (35) may be formed by forming grooves (34) in the outer surface of the core structure, filling the grooves with a fugitive filler (36), depositing and bonding the skin (42), then removing the fugitive material.

In order to study this association of skin changes in relation to hypothyroidism, a study was carried out in the outpatients department of Dermatology of Dayanand Medical College and Hospital, Ludhiana, over a period of 3 months from Jan-March 2005. Thirty two patients were enrolled in the study and parameters were noted regarding history, general symptoms, cutaneous signs and associated diseases. We found gain in weight (71.85% and lethargy (65.62% to be the most common complaints. On cutaneous examination, dry, coarse texture of the skin (56%, pigmentary disorders (37.5% and telogen effluvium (40.62% were the most common findings. Other associated disorders were vitiligo, melasma, pemphigus, alopecia areata, xanthelasma palpebrarum, etc.
The skin is an important organ of defense adaptation and a portal of entry for xenobiotics. It is vulnerable to physical, chemical, and biologic agents and capable of expressing responses to these agents in a variety of pathologic patterns. These patterns are characterized by morphologic and functional features which are elicited by careful examination and test procedures. Cutaneous cancer may result from exposure to nonionizing as well as ionizing radiation, to specific identifiable chemical hazards, and may be enhanced by trauma. Cutaneous hazards of chemical sources are largely found in the workplace and among consumer products, including drugs and toilet goods. Environmental skin diseases and injuries are preventable. Prior to use assessment for safety and for possible risks from exposure to an agent, product, or process is of primary importance in the prevention and control of environmental skin disease and injury

Certain clinically and histologically recognizable skin lesions with a degree of risk of progression to squamous cell carcinoma have been traditionally grouped as precancerous skin conditions but now tend to be classified as in situ carcinomas. This consensus statement discusses various aspects of these lesions: their evaluation by means of clinical and histopathologic features, the initial evaluation of the patient, the identification of risk factors for progression, and the diagnostic and treatment strategies available today.

With respect to skin pedicles (tubular pedicle or direct flap), an estimation of the blood supply is of great importance in making a decision as to when to perform the separation from the original blood supply. This decision is based on empiric observation of the normal time of healing and varies greatly with the site and the concepts of the individual surgery. A number of methods have been proposed for testing the circulation of pedicle skin flaps or tubes, and these methods all seem more complicated and less accurate than the isotope method that is described in this chapter
Full Text Available All multicellular organisms protect themselves from external universe and microorganisms by innate immune sytem that is constitutively present. Skin innate immune system has several different components composed of epithelial barriers, humoral factors and cellular part. In this review information about skin innate immune system and its components are presented to the reader. Innate immunity, which wasn’t adequately interested in previously, is proven to provide a powerfull early protection system, control many infections before the acquired immunity starts and directs acquired immunity to develop optimally
Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

Background: Demodex mites are acari that reside in the pilosebaceous unit of the skin and have been associated with skin disorders. The objective of this study was to investigate the prevalence of Demodex folliculorum (D. folliculorum) mites in polycystic ovary syndrome patients as well as to examine the relationship between Demodex infestation and the presence of acne and oily or dry skin types in polycystic ovary syndrome patients. 41 polycystic ovary syndrome patients and 47 non-polycystic ovary syndrome control subjects were enrolled in the study. polycystic ovary syndrome was diagnosed according to the revised 2003 ESHRE/ASRM polycystic ovary syndrome Consensus Workshop Group diagnostic criteria. Microscopic examination of D. folliculorum mites was carried out by standardized skin surface biopsy. The result was considered positive when there were more than 5 mites per cm2. D. folliculorum was positive in 53.7% of the polycystic ovary syndrome patients and 31.9% of the non-polycystic ovary syndrome group (p=0.052). Demodex positivity was significantly associated with acne (p=0.003) and oily skin (p=0.005) in the polycystic ovary syndrome patients but not in the controls. Our study is limited by the relatively small number of subjects and the observational nature of the study design. Demodex mites might have a role in acne pathogenesis in patients with polycystic ovary syndrome. Anti-Demodex treatment may increase the response to treatment of acne. Further studies are indicated.

Although it was initially assumed that erythropoietin (EPO) was a hormone that only affected erythropoiesis, it has now been proposed that EPO plays an additional key role in the regulation of acute and chronic tissue damage. This is a large, prospective, randomized, double-blind, multi-center study, funded by the German Federal Ministry of Education and Research, and fully approved by the designated ethics committee. The trial, which is to investigate the effects of EPO in severely burned patients, is in its recruitment phase and is being carried out in 13 German burn care centers. A total of 150 patients are to be enrolled to receive study medication every other day for 21 days (EPO 150 IU/kg body weight or placebo). A follow-up of one year is planned. The primary endpoint of this study is the time until complete re-epithelialization of a defined skin graft donor site is reached. Furthermore, clinical parameters such as wound healing, scar formation (using the Vancouver scar scale), laboratory values, quality of life (SF-36), angiogenic effects, and gene- and protein-expression patterns are to be determined. The results will be carefully evaluated for gender differences. We are seeking new insights into the mechanisms of wound healing in thermally injured patients and more detailed information about the role EPO plays, specifically in these complex interactions. We additionally expect that the biomimetic effects of EPO will be useful in the treatment of acute thermal dermal injuries.

POEMS syndrome is a systemic disorder with peripheral neuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and skin changes. The association of POEMS syndrome with lympho-proliferative disorder is very commun. The pathogenesis remains poorly understood but implication of cytokines (interleukins 1 and 6) is suspected. We report a case of a classic POEMS syndrome (with polyneuropathy, hepatomegaly, diabetes melitus, hyperpigmentation, monoclonal IgG lambda, anasarca and solitary plasmocytoma), associated with high serum levels of interleukin 6.

In order to estimate eventual risks to human health as a consequence of incidental and prolonged skin contact, it is necessary to obtain some information on the potential of coal-derived liquids to elicit skin cancer. In addition, it also must be established whether prolonged dermal exposure will produce signs of toxicity not only on the skin but to internal organs. During the past 2 years, they completed a life-long skin painting study with mice designed to answer some of these questions. The following materials were tested: Raw H-coal blend, containing 5700 ppm N; H-coal blend after low hydrotreatment (2650 ppm N); H-coal blend after high hydrotreatment (0.2 ppm N); H-coal home heating oil, a devolatilized version of the high-hydrotreatment H-coal blend; and an H-coal reformed naphtha. Two petroleum-derived references samples were used: Petroleum No. 2 fuel oil and high catalytically cracked naphtha. Benzo(a)pyrene was used as reference substance. Experimental animals were male and female C3H mice
Because of the depletion of ozone in the stratosphere due to chlorofluorocarbons, the screening effect of this ozone layer on ultraviolet radiation (especially the so-called UV-B component) is reduced. This paper describes the impact of increased UV radiation on the human skin. Because of the 'ozone-hole', a distinct increase in the rate of skin cancer is to be expected which will affect all living beings but most of all man - an indirect consequence of the climate development. What makes the increased intensity of UV-B radiation so harmful is the fact that light-induced skin damage accumulates for the period of the life-time of the individual and cannot be reversed. A further thinning of stratospheric ozone would let through, in addition, the more short-waved ('harder') UV-C radiation. The latter, though clinically not significant currently, would then account for a further increase in the rate of malignant skin disease world-wide. (orig.) [de

Skin tone is the most important color category in memory colors. Reproducing it pleasingly is an important factor in photographic color reproduction. Moving skin colors toward their preferred skin color center improves the skin color preference on photographic color reproduction. Two key factors to successfully enhance skin colors are: a method to detect original skin colors effectively even if they are shifted far away from the regular skin color region, and a method to morph skin colors toward a preferred skin color region properly without introducing artifacts. A method for skin color enhancement presented by the authors in the same conference last year applies a static skin color model for skin color detection, which may miss to detect skin colors that are far away from regular skin tones. In this paper, a new method using the combination of face detection and statistical skin color modeling is proposed to effectively detect skin pixels and to enhance skin colors more effectively.
Full Text Available The Brooke-Spiegler syndrome (BSS is an uncommon autosomal dominant disorder characterized by a high affinity to form multiple adnexal neoplasia (skin appendage tumors, especially trichoepitheliomas and cylindromas, and occasionally spiradenomas, which usually appear in the second or third decade of life. To date, only a few cases with this syndrome have been reported. This case report describes a 26-year-old woman who presented to the dermatology department of Qaem Hospital with tumoral lesions on her scalp, face, and forearm. Her father and younger brother were also affected. On examination, several round-to-oval skin-colored papules with a smooth pearly surface measuring 2 to 6 mm in diameter were seen on the mid-face, particularly in the nasolabial folds, the upper lip. Tumors and nodules seen on the scalp were pinkish red, dome-shaped, and to some extent, pedunculated with surface telangiectasia and induration. Histopathology of the facial papules showed trichoepithelioma while that of a scalp nodule showed cylindroma.

Many different heritable connective tissue disorders (HCTD) have been described over the past decades. These syndromes often affect the connective tissue of various organ systems, including heart, blood vessels, skin, joints, bone, eyes, and lungs. The discovery of these HCTD was followed by the identification of mutations in a wide range of genes encoding structural proteins, modifying enzymes, or components of the TGFβ-signaling pathway. Three typical examples of HCTD are Marfan syndrome (MFS), Ehlers-Danlos syndrome (EDS), and Loeys-Dietz syndrome (LDS). These syndromes show some degree of phenotypical overlap of cardiovascular, skeletal, and cutaneous features. MFS is typically characterized by cardiovascular, ocular, and skeletal manifestations and is caused by heterozygous mutations in FBN1 , coding for the extracellular matrix (ECM) protein fibrillin-1. The most common cardiovascular phenotype involves aortic aneurysm and dissection at the sinuses of Valsalva. LDS is caused by mutations in TGBR1/2 , SMAD2/3 , or TGFB2/3 , all coding for components of the TGFβ-signaling pathway. LDS can be distinguished from MFS by the unique presence of hypertelorism, bifid uvula or cleft palate, and widespread aortic and arterial aneurysm and tortuosity. Compared to MFS, LDS cardiovascular manifestations tend to be more severe. In contrast, no association is reported between LDS and the presence of ectopia lentis, a key distinguishing feature of MFS. Overlapping features between MFS and LDS include scoliosis, pes planus, anterior chest deformity, spontaneous pneumothorax, and dural ectasia. EDS refers to a group of clinically and genetically heterogeneous connective tissue disorders and all subtypes are characterized by variable abnormalities of skin, ligaments and joints, blood vessels, and internal organs. Typical presenting features include joint hypermobility, skin hyperextensibility, and tissue fragility. Up to one quarter of the EDS patients show aortic aneurysmal

The experience of dealing with skin contamination incidents at The Radiochemical Centre over a 3-year period is presented. Data are given for the primary isotopes involved, the duration of skin contamination, and the skin doses that arise from these incidents. The methods employed in performing dosimetry for skin contamination are discussed and examples involving the isotopes carbon-14 and indium-111 are described. For skin contamination incidents, the mode of penetration of the activity into skin is normally not known and this can be of major significance for the final skin dose estimate. The operational health physics difficulties encountered in complying with both ICRP-26 and UK legislation for skin contamination are considered. In the event of multiple exposure (i.e. skin doses calculated from whole body film badges, extremity TLD dose meters and skin contamination) there is ambiguity in the precise meaning of the skin dose. The usefulness of Derived Working Levels is also discussed. Experience at The Radiochemical Centre has shown that good plant design, proper training and prompt action in dealing with contamination incidents ensures that overexposures to skin from accidental contamination are rare occurrences.

A technique and device provides absolute skin dosimetry in real time at multiple tissue depths simultaneously. The device uses a phoswich detector which has multiple scintillators embedded at different depths within a non-scintillating material. A digital pulse processor connected to the phoswich detector measures a differential distribution (dN/dH) of count rate N as function of pulse height H for signals from each of the multiple scintillators. A digital processor computes in real time from the differential count-rate distribution for each of multiple scintillators an estimate of an ionizing radiation dose delivered to each of multiple depths of skin tissue corresponding to the multiple scintillators embedded at multiple corresponding depths within the non-scintillating material.

Ablative laser resurfacing has evolved as a safe and effective treatment for skin rejuvenation. Although traditional lasers were associated with significant thermal damage and lengthy recovery, advances in laser technology have improved safety profiles and reduced social downtime. CO2 lasers remain the gold standard of treatment, and fractional ablative devices capable of achieving remarkable clinical improvement with fewer side effects and shorter recovery times have made it a more practical option for patients. Although ablative resurfacing has become safer, careful patient selection and choice of suitable laser parameters are essential to minimize complications and optimize outcomes. This article describes the current modalities used in ablative laser skin resurfacing and examines their efficacy, indications, and possible side effects.

Full Text Available Salmonella attached to the poultry skin is a major source of carcass contamination during processing. Once attached to the poultry skin, it is difficult to detach and inactivate Salmonella by commonly used antimicrobial agents since the pathogen is entrapped deeply in the feather follicles and the crevices on the skin. Essential oils could be natural, safe, and effective alternatives to synthetic antimicrobial agents during commercial and organic processing setup. The present study evaluated the efficacy of pimenta (Pimenta officinalis Lindl. leaf essential oil (PEO, and its nanoemulsion in reducing Salmonella Heidelberg attachment on to turkey (Meleagris gallopavo skin during simulated scalding (65°C and chilling (4°C steps in poultry processing. A multidrug resistant S. Heidelberg isolate from the 2011 ground turkey outbreak in the United States was used in the study. Results showed that PEO and the nanoemulsion resulted in significant reduction of S. Heidelberg attachment on turkey skin. Turkey skin samples treated with 1.0% PEO for 5 min resulted in >2 log10 CFU/sq. inch reduction of S. Heidelberg at 65 and 4°C, respectively (n = 6; P < 0.05. Similarly, skin samples treated with 1.0% pimenta nanoemulsion (PNE for 5 min resulted in 1.5- and 1.8- log10 CFU/sq. inch reduction of S. Heidelberg at 65 and 4°C, respectively (n = 6; P < 0.05. In addition, PEO and PNE were effective in reducing S. Heidelberg on skin during short-term storage at 4 and 10°C (temperature abuse (n = 6; P < 0.05. No Salmonella was detected in the dipping solution containing 0.5 or 1.0% PEO or PNE, whereas a substantial population of the pathogen survived in the control dipping solution. The results were validated using scanning electron -, and confocal - microscopy techniques. PEO or PNE could be utilized as an effective antimicrobial agent to reduce S. Heidelberg attachment to turkey skin during poultry processing.
