    Androgenetic alopecia (AGA), or male pattern hair loss, affects approximately 50% of the male population. AGA is an androgen-related condition in genetically predisposed individuals. There is no treatment to completely reverse AGA in advanced stages, but with medical treatment (eg, finasteride, minoxidil, or a combination of both), the progression can be arrested and partly reversed in the majority of patients who have mild to moderate AGA. Combination with hair restoration surgery leads to best results in suitable candidates. Physicians who specialize in male health issues should be familiar with this common condition and all the available approved treatment options.

    Full Text Available Androgenetic alopecia is hair thinning due to the stimulation of hair follicles to androgens. Incidence in men is higher than in women, it is because men have a degree higher 5? reductase. This condition can cause both physical and psychological effects to the patient. Physical effects due to baldness cause hair loss as a function of protection against heat, cold and trauma. While psychologically can affect self-esteem and self-perception of the patient. Androgenetic alopecia in men influenced by the androgen dihydrotestosterone and genetic predisposition, although the physiology remains unclear. Modality in the management of androgenetic alopecia in males patients including pharmacotherapy, hair transplants and cosmetic approach. According to the Food and Drug Administration (FDA, there are two main drugs are safe and effective in the long term given to men with androgenetic alopecia are minoxidil and finasteride. Although the mechanism of action and route of administration are different, but both drugs have similar effectiveness in stopping the progression of androgenetic alopecia in men.

    Androgenetic alopecia (AGA), also known in women as female pattern hair loss, is caused by androgens in genetically susceptible women and men. The thinning begins between ages 12 and 40 years, the inheritance pattern is polygenic, and the incidence is the same as in men. In susceptible hair follicles, dihydrotestosterone binds to the androgen receptor, and the hormone-receptor complex activates the genes responsible for the gradual transformation of large terminal follicles to miniaturized follicles. Both young women and young men with AGA have higher levels of 5alpha reductase and androgen receptor in frontal hair follicles compared to occipital follicles. At the same time, young women have much higher levels of cytochrome p-450 aromatase in frontal follicles than men who have minimal aromatase, and women have even higher aromatase levels in occipital follicles. The diagnosis of AGA in women is supported by early age of onset, the pattern of increased thinning over the frontal/parietal scalp with greater density over the occipital scalp, retention of the frontal hairline, and the presence of miniaturized hairs. Most women with AGA have normal menses and pregnancies. Extensive hormonal testing is usually not needed unless symptoms and signs of androgen excess are present such as hirsutism, severe unresponsive cystic acne, virilization, or galactorrhea. Topical minoxidil solution is the only drug available for promoting hair growth in women with AGA. Efficacy has been shown in double-blind studies using hair counts and hair weight.

    Androgenetic alopecia (AGA) is a dihydrotestosterone (DHT)-mediated process, characterized by continuous miniaturization of androgen reactive hair follicles and accompanied by perifollicular fibrosis of follicular units in histological examination. Testosterone (T: 10(-9)-10(-7) M) treatment increased the expression of type I procollagen at mRNA and protein level. Pretreatment of finasteride (10(-8) M) inhibited the T-induced type I procollagen expression at mRNA (40.2%) and protein levels (24.9%). T treatment increased the expression of transforming growth factor-beta 1 (TGF-beta1) at protein levels by 81.9% in the human scalp dermal fibroblasts (DFs). Pretreatment of finasteride decreased the expression of TGF-beta1 protein induced by an average of T (30.4%). The type I procollagen expression after pretreatment of neutralizing TGF-beta1 antibody (10 microg/ml) was inhibited by an average of 54.3%. Our findings suggest that T-induced TGF-beta1 and type I procollagen expression may contribute to the development of perifollicular fibrosis in the AGA, and the inhibitory effects on T-induced procollagen and TGF-beta1 expression may explain another possible mechanism how finasteride works in AGA.

    Androgenetic alopecia In men, or male pattern baldness, is recognized increasingly as a physically and psychologically harmful medical condition that can be managed effectively by generalist clinicians. This article discusses the clinical manifestations, epidemiology, physical and psychosocial importance, pathophysiology, diagnosis, and management of androgenetic alopecia in men. Androgenetic alopecia affects at least half of white men by the age of 50 years. Although androgenetic alopecia does not appear to cause direct physical harm, hair loss can result in physical harm because hair protects against sunburn, cold, mechanical injury, and ultraviolet light. Hair loss also can psychologically affect the balding individual and can Influence others' perceptions of him. A progressive condition, male pattern baldness is known to depend on the presence of the androgen dihydrotestosterone and on a genetic predisposition for this condition, but its pathophysiology has not been elucidated fully. Pharmacotherapy, hair transplantation, and cosmetic aids have been used to manage male pattern baldness. Two US Food and Drug Administration-approved hair-loss pharmacotherapies-the potassium channel opener minoxidil and the dihydrotestosterone synthesis inhibitor finasteride--are safe and effective for controlling male pattern baldness with long-term daily use. Regardless of which treatment modality is chosen for male pattern baldness, defining and addressing the patient's expectations regarding therapy are paramount in determining outcome.

    Full Text Available Background: Finasteride is a widely used drug in dermatology for the treatment of androgenetic alopecia. There are many reports of associated sexual side effects. This article reviews the use of once-daily 1 mg finasteride in androgenetic alopecia and its associated sexual adverse effects. Methods: A literature search was performed to collect data on the use of finasteride in male pattern baldness. Relevant literature published till March 2014 was obtained from MEDLINE, EMBASE, CINAHL, Cochrane registers and LILACS. The keywords "finasteride", "male pattern baldness" and "androgenetic alopecia" were used for literature search. Similarly, a search was done for finasteride in female pattern hair loss with keywords "female pattern baldness", "finasteride" and "female pattern alopecia". All systematic reviews, meta-analyses, national guidelines, randomized controlled trials, prospective open label studies and retrospective case series in the English literature were reviewed. Results: Two hundred sixty two studies were evaluated, twelve of which fulfilled the inclusion criteria. Conclusions and Recommendations: Current evidence on the safety of finasteride indicates that it is safe but there is growing concern about its sexual side effects. In view of this, proper information should be provided to patients prior to starting treatment (Level of recommendation 1+, Grade of recommendation B. The reported sexual side effects are few and reverse with stoppage of the drug (Grade of recommendation B but further studies are required.

    Full Text Available Androgenetic alopecia (AGA is the most common acquired non scarring alopecia in humans caused by androgen hormones in the setting of a genetic predisposition. Usually AGA starts after puberty, but recently it has been observed also in adolescents. Their mean age was 13 years with a slight prevalence in males. The premature AGA may be caused by environmental, alimentary (meat and milk or cosmetics overexposure to sexual hormones or to endocrine disrupters (EDs. EDs are "exogenous substances that interfere with the synthesis, secretion, transport, binding, action, or elimination of natural hormones in the body causing adverse effects to human health" and they are able bind to the steroid hormone receptors. Early onset AGA may be linked to the well known phenomenon of early puberty caused in some cases by hormones contained in food or by environmental chemicals. Therefore it is likely that the EDs may play a role also in the pathogenesis of early-onset AGA.

    Full Text Available Androgenetic alopecia (AGA is a type of alopecia non sikatrik that most often occur, especially in men. AGA is hereditary baldness and form distinctive patterns. Causes related to AGA estimated serum androgen levels, especially 5-?-dehydrotestosterone (DHT, which can lead to miniaturization of the hair follicle. Finasteride is one of drugs that proven effective in treating hair loss caused by AGA. Finasteride is a 4-azasteroid components that are competitive and specific inhibitor of the enzyme 5-?-reductase type II, an enzyme that converts testosteron into intracellular DHT. By inhibiting the enzyme 5-?-reductase type II, conversion of testosteron to DHT inhibited, thereby causing a significant decrease in serum and tissue DHT concentrations. The use of finasteride 1 mg per day proven to effectively treat AGA in men.

    Full Text Available Introduction: Androgenetic alopecia (AGA is one of the most common dermatologic disorders with a multifactorial etiology. Inflammatory activators such as Demodex infestation may play a role in the pathogenesis of some cases of androgenetic alopecia that do not respond to common treatments such as minoxidil and finasteride. The goal of this study is to evaluate the relationship between Demodex infestation and AGA. Materials and Methods: In this case-control study, 41 patients with AGA referred to the Dermatology Clinic of Imam Reza Hospital and 33 healthy individuals were evaluated as control. All of them were between 20 and 40 years old men. In order to identify Demodex infestation they were referred to the Parasitology laboratory. Results: Demodex was detected in 19.5% of patients and 15.2% of controls; therefore, there was no significant relationship between them statistically ( P = 0.0787. Most of patients (85.4% had greasy hair. The most common pattern of baldness was II degree in Hamilton scale. Conclusion: There is no relation between AGA and Demodex.

    Full Text Available Background: Androgenetic alopecia (AGA or male pattern baldness (MPB has been found to be associated with the risk of coronary artery disease (CAD. The well-known risk factors are family history of CAD, hypertension, increased body mass index (BMI, central obesity, hyperglycemia, and dyslipidemia. The newer risk factors are serum lipoprotein-a (SL-a, serum homocysteine (SH, and serum adiponectin (SA. Aim : Identifying individuals at risk of CAD at an early age might help in preventing CAD and save life. Hence, a comparative study of CAD risk factors was planned in 100 males of AGA between the age of 25 and 40 years with equal number of age- and sex-matched controls. Materials and Methods : Patients of AGA grade II or more of Hamilton and Norwood (HN Scale and controls were examined clinically and advised blood test. The reports were available for fasting blood sugar (FBS, serum total serum cholesterol (SC in 64 cases, 64 controls; lipoproteins (high, low, very low density, HDL, LDL, VLDL, serum triglycerides (ST in 63 cases, 63 controls; SL-a in 63 cases, 74 controls; SH in 56 cases, 74 controls; and SA in 62 cases, 74 controls. Results : In these cases family history (FH of AGA and CAD was significantly high. The blood pressure (BP was also found to be significantly high in the cases. The difference of mean serum HDL, LDL, VLDL, ST, SH, and SL-a in cases and controls were statistically significant and with increasing grade of AGA, the risk factors also increased. Conclusion : Patients with AGA appear to be at an increased risk of developing CAD, therefore, clinical evaluation of cases with AGA of grade II and above may be of help in preventing CAD in future.

    BACKGROUND Androgenetic alopecia (AGA) is a patterned hair loss occurring due to systemic androgen and genetic factors. It is the most common cause of hair loss in both genders. In recent years, many studies investigating the relation between systemic diseases and androgenetic alopecia presented controversial results. OBJECTIVES In this study we aimed to investigate the frequency of androgenetic alopecia, the presence of accompanying systemic diseases, the relation between body mass index and androgenetic alopecia severity and the association of hyperandrogenemia signs with androgenetic alopecia in patients who referred to our outpatient clinic. METHODS Patients who referred to our clinic between October 2013 and May 2014 were included in the study. Diagnosis of androgenetic alopecia was made upon clinical findings. Presence of seborrhea and acne in both genders, and hirsutism in women, were examined. Age, gender, smoking habit and alcohol consumption, age of onset of androgenetic alopecia, family history, accompanying systemic diseases and abnormalities of menstrual cycle were recorded. RESULTS 954 patients (535 women, 419 men) were included in the study. Androgenetic alopecia prevalence found was 67.1% in men and 23.9% in women. Androgenetic alopecia prevalence and severity were correlated with age in both genders (p=0,0001). Frequency of accompanying systemic diseases were not significantly different between patients with and without androgenetic alopecia (p=0,087), except for hypertension, which was significantly more frequent in men with androgenetic alopecia aged between 50 and 59 years. Study limitations: Despite the exclusion of other causes of alopecia, differentiation of Ludwig grade 1 AGA from telogen effluvium based on clinical features alone is difficult. CONCLUSIONS In our study the rate of androgenetic alopecia was found to be higher than the other studies made in Asian and Caucasian populations. PMID:28225954

    Androgenetic alopecia is the most common hair loss disorder, affecting both men and women. Initial signs of androgenetic alopecia usually develop during teenage years leading to progressive hair loss with a pattern distribution. Moreover, its frequency increases with age and affects up to 80 % Caucasian men and 42 % of women. Patients diagnosed with androgenetic alopecia may undergo significant impairment of quality of life. Despite the high prevalence and the variety of therapeutic options available, there have been no national or international evidence-based guidelines for the treatment of androgenetic alopecia in men and women so far. Therefore, the European Dermatology Forum (EDF) initiated a project to develop an evidence-based S3 guideline for the treatment of andro-genetic alopecia. Based on a systematic literature research the efficacy of the currently available therapeutic options was assessed and therapeutic recommendations were passed in a consensus conference. The purpose of the guideline is to provide dermatologists as well as general practitioners with an evidence-based tool for choosing an efficacious and safe therapy for patients with androgenetic alopecia.

    Full Text Available Background: The effectiveness of finasteride and dutasteride in women with androgenetic alopecia has been the subject of debate. Aim: To evaluate the effectiveness of finasteride and dutasteride on hair loss in women with androgenetic alopecia over a period of 3 years. Methods: From a database containing systematically retrieved data on 3500 women treated for androgenetic alopecia between 2002 and 2012 with finasteride 1.25 mg or dutasteride 0.15 mg, a random sample stratified for age and type of medication was taken to yield 30 women in two age categories: below and above 50 years, and for both medications. Hair thickness of the three thinnest hairs was measured from standardized microscopic images at three sites of the scalp at the start of the treatment and after 3 years of continuous medication intake. The macroscopic images were evaluated independently by three European dermatologists/hair experts. The diagnostic task was to identify the image displaying superior density of the hair. Results: Both age categories showed a statistically significant increase in hair thickness from baseline over the 3-year period for finasteride and dutasteride (signed rank test, P = 0.02. Hair thickness increase was observed in 49 (81.7% women in the finasteride group and in 50 (83.3% women in the dutasteride group. On average, the number of post-treatment images rated as displaying superior density was 124 (68.9% in the finasteride group, and 118 (65.6% in the dutasteride group. Dutasteride performed statistically significantly better than finasteride in the age category below 50 years at the central and vertex sites of the scalp. Conclusions: Finasteride 1.25 mg and dutasteride 0.15 mg given daily for 3 years effectively increased hair thickness and arrested further deterioration in women with androgenetic alopecia.

    Full Text Available BACKGROUND: Androgenetic alopecia is the most common form of hair loss. It is a clinical entity of relevant interest and presents a significant psychosocial impact as it undermines self-esteem and quality of life in female patients due to the importance of the hair for people's facial balance. OBJECTIVE: The purpose of the present study is to evaluate dermoscopic signs in women clinically diagnosed with androgenetic alopecia. METHOD: Observational study with 34 women between 17 and 68 years old who were diagnosed with androgenetic alopecia. All of them underwent photographic sessions with a 10x magnification dermoscope and a digital camera zoom set to 20x magnification and 40x magnification on the scalp frontal midline. RESULTS: All patients showed miniaturization. A peripilar brown halo was found in 22 patients, honeycomb-like scalp pigmentation was found in 14 and yellow dots in only 1 patient. Recent studies show dermoscopy as the new tool for diagnosis assistance and treatment follow up in scalp disorders. Our study used an ordinary dermoscope and we evaluated several findings reported in the literature with significant clarity and easiness. CONCLUSION: The dermoscope, which is used by dermatologists on a daily basis, is an excellent tool to assist in early diagnosis and assessment of therapeutic response in androgenetic alopecia.FUNDAMENTOS: Alopecia androgenética é forma mais comum de queda de cabelo.

    Androgenetic alopecia (AGA) is the most common hair loss disorder, affecting both men and women. Due to the frequency and the often significant impairment of life perceived by the affected patients, competent advice, diagnosis and treatment is particularly important. As evidence-based guidelines on hair disorders are rare, a European consensus group was constituted to develop guidelines for the diagnostic evaluation and treatment of AGA. This S1 guideline for diagnostic evaluation of AGA in men, women and adolescents reviews the definition of AGA and presents expert opinion-based recommendations for sex-dependent steps in the diagnostic procedure.

    Androgenetic alopecia, known in men as male pattern baldness (MPB), is a very conspicuous condition that is particularly frequent among European men and thus contributes markedly to variation in physical appearance traits amongst Europeans. Recent studies have revealed multiple genes and polymorphisms to be associated with susceptibility to MPB. In this study, 50 candidate SNPs for androgenetic alopecia were analyzed in order to verify their potential to predict MPB. Significant associations were confirmed for 29 SNPs from chromosomes X, 1, 5, 7, 18 and 20. A simple 5-SNP prediction model and an extended 20-SNP model were developed based on a discovery panel of 305 males from various European populations fitting one of two distinct phenotype categories. The first category consisted of men below 50 years of age with significant baldness and the second; men aged 50 years or older lacking baldness. The simple model comprised the five best predictors: rs5919324 near AR, rs1998076 in the 20p11 region, rs929626 in EBF1, rs12565727 in TARDBP and rs756853 in HDAC9. The extended prediction model added 15 SNPs from five genomic regions that improved overall prevalence-adjusted predictive accuracy measured by area under the receiver characteristic operating curve (AUC). Both models were evaluated for predictive accuracy using a test set of 300 males reflecting the general European population. Applying a 65% probability threshold, high prediction sensitivity of 87.1% but low specificity of 42.4% was obtained in men aged <50 years. In men aged ≥50, prediction sensitivity was slightly lower at 67.7% while specificity reached 90%. Overall, the AUC=0.761 calculated for men at or above 50 years of age indicates these SNPs offer considerable potential for the application of genetic tests to predict MPB patterns, adding a highly informative predictive system to the emerging field of forensic analysis of externally visible characteristics.

    Full Text Available Androgenetic alopecia, known in men as male pattern baldness (MPB, is a very conspicuous condition that is particularly frequent among European men and thus contributes markedly to variation in physical appearance traits amongst Europeans. Recent studies have revealed multiple genes and polymorphisms to be associated with susceptibility to MPB. In this study, 50 candidate SNPs for androgenetic alopecia were analyzed in order to verify their potential to predict MPB. Significant associations were confirmed for 29 SNPs from chromosomes X, 1, 5, 7, 18 and 20. A simple 5-SNP prediction model and an extended 20-SNP model were developed based on a discovery panel of 305 males from various European populations fitting one of two distinct phenotype categories. The first category consisted of men below 50 years of age with significant baldness and the second; men aged 50 years or older lacking baldness. The simple model comprised the five best predictors: rs5919324 near AR, rs1998076 in the 20p11 region, rs929626 in EBF1, rs12565727 in TARDBP and rs756853 in HDAC9. The extended prediction model added 15 SNPs from five genomic regions that improved overall prevalence-adjusted predictive accuracy measured by area under the receiver characteristic operating curve (AUC. Both models were evaluated for predictive accuracy using a test set of 300 males reflecting the general European population. Applying a 65% probability threshold, high prediction sensitivity of 87.1% but low specificity of 42.4% was obtained in men aged <50 years. In men aged ≥50, prediction sensitivity was slightly lower at 67.7% while specificity reached 90%. Overall, the AUC=0.761 calculated for men at or above 50 years of age indicates these SNPs offer considerable potential for the application of genetic tests to predict MPB patterns, adding a highly informative predictive system to the emerging field of forensic analysis of externally visible characteristics.

    Numerous studies have investigated a probable association between androgenetic alopecia (AGA) and cardiovascular disease (CVD) by researching limited and dispersed parameters. We aimed to evaluate both traditional and non-traditional cardiovascular risk factors in male patients with early-onset AGA. This case-control study included 68 participants: 51 male patients with early-onset AGA and 17 healthy male controls. Patients with AGA were classified into three groups according to the Hamilton-Norwood scale and the presence of vertex hair loss. Traditional and non-traditional cardiovascular risk factors were examined in all study subjects. Metabolic syndrome was diagnosed in 25 patients with AGA and in two control subjects (p baldness and controls (p < 0.05). The pulse-wave velocity values were also found to be significantly higher in patients (p < 0.001). A limitation of this study was the small study population. In conclusion, vertex pattern AGA appears to be a marker for early atherosclerosis. This finding supports the hypothesis that early-onset AGA alone could be an independent risk factor for CVD and metabolic syndrome.

    Dermal papilla cells (DPCs) taken from male androgenetic alopecia (AGA) patients undergo premature senescence in vitro in association with the expression of p16(INK4a), suggesting that DPCs from balding scalp are more sensitive to environmental stress than nonbalding cells. As one of the major triggers of senescence in vitro stems from the cell "culture shock" owing to oxidative stress, we have further investigated the effects of oxidative stress on balding and occipital scalp DPCs. Patient-matched DPCs from balding and occipital scalp were cultured at atmospheric (21%) or physiologically normal (2%) O2. At 21% O2, DPCs showed flattened morphology and a significant reduction in mobility, population doubling, increased levels of reactive oxygen species and senescence-associated β-Gal activity, and increased expression of p16(INK4a) and pRB. Balding DPCs secreted higher levels of the negative hair growth regulators transforming growth factor beta 1 and 2 in response to H2O2 but not cell culture-associated oxidative stress. Balding DPCs had higher levels of catalase and total glutathione but appear to be less able to handle oxidative stress compared with occipital DPCs. These in vitro findings suggest that there may be a role for oxidative stress in the pathogenesis of AGA both in relation to cell senescence and migration but also secretion of known hair follicle inhibitory factors.

    Male baldness is the most common diagnosis in men that present with hair loss. It is a genetically determined condition that is clearly an androgen-dependent trait, mainly driven by dihydrotestosterone action on the hair follicles, leading to miniaturization. Although in general this condition is socially accepted as a natural process in a man's life, for some individuals it might significantly impact quality of life, reducing self-esteem and increasing stress. This chapter encompasses the most important aspects of the practical evaluation (clinical features, trichoscopy, trichogram, histopathology, relevant blood tests) and management of male baldness, diffuse baldness and senescent alopecia.

    Full Text Available Background: Platelet-rich plasma (PRP is defined as an autologous concentration of plasma with a greater count of platelets than that of whole blood. Its action depends on the released growth factors from platelets. It has been investigated and used in numerous fields of medicine. Recently, PRP has received growing attention as a potential therapeutic tool for hair loss. Aims: To evaluate the efficacy and safety of PRP injections in the scalp of patients with androgenetic alopecia. Settings and Design: Prospective cohort study. Materials and Methods: 20 patients, 18 males and 2 females, with androgenetic alopecia were enrolled in the study. PRP was prepared using a single spin method (Regenlab SA. Upon activation, it was injected in the androgen-related areas of scalp. Three treatment sessions were performed with an interval of 21 days and a booster session at 6 months following the onset of therapy. Statistical Analysis: Statistical analysis of the data was performed using the Statistical Package for the Social Sciences (SPSS, version 19.0 (IBM, NY, USA. Results: Hair loss reduced and at 3 months it reached normal levels. Hair density reached a peak at 3 months (170.70 ± 37.81, P < 0.001. At 6 months and at 1 year, it was significantly increased, 156.25 ± 37.75 (P < 0.001 and 153.70 ± 39.92 (P < 0.001 respectively, comparing to baseline. Patients were satisfied with a mean result rating of 7.1 on a scale of 1-10. No remarkable adverse effects were noted. Conclusions: Our data suggest that PRP injections may have a positive therapeutic effect on male and female pattern hair loss without remarkable major side effects. Further studies are needed to confirm its efficacy.

    Two percent topical minoxidil is the only US Food and Drug Administration-approved drug for the treatment of female androgenetic alopecia (AGA). Its success has been limited by the low percentage of responders. Meta-analysis of several studies reporting the number of responders to 2% minoxidil monotherapy indicates moderate hair regrowth in only 13-20% of female patients. Five percent minoxidil solution, when used off-label, may increase the percentage of responders to as much as 40%. As such, a biomarker for predicting treatment response would have significant clinical utility. In a previous study, Goren et al. reported an association between sulfotransferase activity in plucked hair follicles and minoxidil response in a mixed cohort of male and female patients. The aim of this study was to replicate these findings in a well-defined cohort of female patients with AGA treated with 5% minoxidil daily for a period of 6 months. Consistent with the prior study, we found that sulfotransferase activity in plucked hair follicles predicts treatment response with 93% sensitivity and 83% specificity. Our study further supports the importance of minoxidil sulfation in eliciting a therapeutic response and provides further insight into novel targets for increasing minoxidil efficacy.

    The pathogenesis of androgenetic alopecia (AGA, male-pattern baldness) is driven by androgens, and genetic predisposition is the major prerequisite. Candidate gene and genome-wide association studies have reported that single-nucleotide polymorphisms (SNPs) at eight different genomic loci are associated with AGA development. However, a significant fraction of the overall heritable risk still awaits identification. Furthermore, the understanding of the pathophysiology of AGA is incomplete, and each newly associated locus may provide novel insights into contributing biological pathways. The aim of this study was to identify unknown AGA risk loci by replicating SNPs at the 12 genomic loci that showed suggestive association (5 × 10(-8)

    Androgenetic alopecia, or male pattern baldness, is a complex condition with a strong heritable component. In 2001, we published the first significant evidence of a genetic association between baldness and a synonymous coding SNP (rs6152) in the androgen receptor gene, AR. Recently, this finding was replicated in three independent studies, confirming an important role for AR in the baldness phenotype. In one such replication study, it was claimed that the causative variant underlying the association was likely to be the polyglycine (GGN) repeat polymorphism, one of two apparently functional triplet repeat polymorphisms located in the exon 1 transactivating domain of the gene. Here, we extend our original association finding and present comprehensive evidence from approximately 1,200 fathers and sons drawn from 703 families of the Victorian Family Heart Study, a general population Caucasian cohort, that neither exon 1 triplet repeat polymorphism is causative in this condition. Seventy-eight percent of fathers (531/683) and 30% of sons (157/520) were affected to some degree with AGA. We utilised statistical methods appropriate for the categorical nature of the phenotype and familial structure of the cohort, and determined that whilst SNP rs6152 was strongly associated with baldness (P baldness, but also for the many other complex conditions that have thus far been linked to AR.

    Full Text Available Background: The epidemiological evaluation of androgenetic alopecia (AGA is based mainly on direct observation and questionnaires. The international epidemiology and environmental risk factors of AGA in young Caucasian men remain unknown. Aim: To use photographs and data from the Internet to evaluate severe AGA and generate greater understanding of the international epidemiology of the disorder in young Caucasian men. Materials and Methods: A population-based cross-sectional study design was used. The sample included 26,340 Caucasian men aged 30 to 40 years who had uploaded profiles to two dating websites. Their photographs were evaluated for AGA and graded as follows: severe AGA (Norwood type VI-VII, non-severe AGA, and unknown. Epidemiological data were collected from the sites. Logistic regression was used to analyze the effect of risk factors on the prevalence of severe AGA. Results : The overall success rate for identifying severe AGA by indirect evaluation of Internet photographs was 94%. The prevalence of severe AGA was 15.33% overall and varied significantly by geographical region. The risk of having severe AGA was increased by 1.092 for every year of age between 30 and 40 years. Severe AGA was more prevalent in subjects with higher body mass index. Conclusions: Photographs from the Internet can be used to evaluate severe AGA in epidemiological studies. The prevalence of severe AGA in young Caucasian men increases with age and varies by geographical region. Body mass index is an environmental risk factor for severe AGA.

    Full Text Available Background: Finasteride, a type P-selective 5a-reductase inhibitor, as a causative agent of decreasing dihydroxy testestrone (DHT level, is effective in the treatment of male androgenic alopecia. Aim: We compared the local and oral finasteride in the treatment of androgenic alopecia. Method: This is a double blind, randomized clinical trial study of 45 male patients, who were referred with alopecia to the private clinics and departments in Boo-Ali Sina Hospital, in Sari. Patients with male androgenic alopecia were selected according to the history and physical examinations. The patients were randomly divided into two: topical finasteride (A and oral finasteride (B groups. Topical finasteride group (A received a topical gel of 1% finasteride and placebo tablets, while the oral finasteride group (B received finasteride tablets (1 mg and gel base (without drug as placebo for 6 months. The patients were followed by clinical observation and recording of side effects prior to the treatment and at the end of first week, and then by a monthly follow-up. The size of bald area, total hair count, and terminal hair were studied. Data were analyzed by descriptive and Chi-square statistical test. Results: The mean duration of hair loss was 18.8±23.10 months. Each month the terminal hair, size of bald area and hair count between the two groups were compared. There were no significant differences between the two groups as a viewpoint of hair thickness, hair counts and the size of bald area. Serial measurements indicated a significant increase in hair counts and terminal hair counts between the two groups. Conclusions: The results of this study showed that the therapeutic effects of both finasteride gel and finasteride tablet were relatively similar to each other.

    Full Text Available The hair follicle is a complete mini-organ that lends itself as a model for investigation of a variety of complex biological phenomena, including stem cell biology, organ regeneration and cloning.  The arrector pili muscle inserts into the hair follicle at the level of the bulge- the epithelial stem cell niche.  The arrector pili muscle has been previously thought to be merely a bystander and not to have an active role in hair disease. Computer generated 3D reconstructions of the arrector pili muscle have helped explain why women with androgenetic alopecia (AGA experience diffuse hair loss rather than the patterned baldness seen in men.  Loss of attachment between the bulge stem cell population and the arrector pili muscle also explains why miniaturization is irreversible in AGA but not alopecia areata. A new model for the progression of AGA is presented.

    Full Text Available Pumpkin seed oil (PSO has been shown to block the action of 5-alpha reductase and to have antiandrogenic effects on rats. This randomized, placebo-controlled, double-blind study was designed to investigate the efficacy and tolerability of PSO for treatment of hair growth in male patients with mild to moderate androgenetic alopecia (AGA. 76 male patients with AGA received 400 mg of PSO per day or a placebo for 24 weeks. Change over time in scalp hair growth was evaluated by four outcomes: assessment of standardized clinical photographs by a blinded investigator; patient self-assessment scores; scalp hair thickness; and scalp hair counts. Reports of adverse events were collected throughout the study. After 24 weeks of treatment, self-rated improvement score and self-rated satisfaction scores in the PSO-treated group were higher than in the placebo group (P = 0.013, 0.003. The PSO-treated group had more hair after treatment than at baseline, compared to the placebo group (P<0.001. Mean hair count increases of 40% were observed in PSO-treated men at 24 weeks, whereas increases of 10% were observed in placebo-treated men (P<0.001. Adverse effects were not different in the two groups.

    Full Text Available BACKGROUND: Scarring alopecias are classified into primary and secondary types according to the initial site of inflammation. In primary scarring alopecias, the hair follicle is the main target of destruction; the term secondary cicatricial alopecia implies that follicular destruction is not the primary pathologic event. AIMS: To review the histopathologic diagnoses of cases of cicatricial alopecia in order to classify them according to the North American Hair Research Society. PATIENTS AND METHODS: Patients with biopsy specimens diagnosed as cicatricial alopecia seen from 2000 to 2005 at the Dermatologic Department of Hospital das Clinicas, São Paulo University Medical School had hematoxylin and eosin, Periodic acid-Schiff and Weigert stained slides reevaluated and sub-typed into different primary cicatricial alopecias. RESULTS: Thirty-eight cases of primary cicatricial alopecias were reclassified as: chronic cutaneous lupus (17, lichen planus pilaris (4, pseudopelade of Brocq (12, folliculitis decalvans (3, dissecting folliculitis (1, and non-specific scarring alopecia (1. In our cases, the methods employed allowed an accurate diagnosis in 12 of 13 cases (92.3% previously classified as non-specific cicatricial alopecias. CONCLUSIONS: Even in the late, pauci or non-inflammatory phases, an approach with systematic evaluation of a constellation of criteria in routine hematoxylin and eosin stain, Periodic acid-Schiff and Weigert stain allowed for a more accurate diagnosis of cicatricial alopecias.

    Objective To evaluate the efficacy and safety of low⁃level laser therapy(LLLT)for androgenetic alopecia, and to compare the therapeutic effect of LLLT alone versus in combination with finasteride tablets. Methods Thirty⁃nine male patients were randomly divided into the LLLT group(n=21)and combination group(n=18)to be treated with LLLT alone or in combination with oral finasteride tablets(1 mg/d)for 6 months. LLLT was given twice a week, and each session lasted 30 minutes. All the patients were photographed and asked to fill a questionnaire about subjective symptoms, and hair density (the number of hairs per unit area on the scalp) was determined by using a dermatoscope to evaluate the grade of alopecia, before the treatment, and 3 and 6 months after the treatment. Results The hair density in the LLLT group was significantly higher after 6 months than after 3 months of treatment and before the treatment(184.59 ± 21.17 vs. 169.24 ± 29.21 and 166.67 ± 32.94 hairs/cm2, both P 0.05). The hair density in the combination group significantly increased after 6 and 3 months of treatment compared with that before the treatment(201.80 ± 16.55 and 186.39 ± 17.97 vs. 157.85 ± 27.97 hairs/cm2, both P 0.05), but the combination group showed increased hair density compared with the LLLT group after 3 and 6 months of treatment(both P 0.05). During the treatment, 24(62%)patients felt less greasy, and 22(56%)reported less hair loss, with no discomforts reported by the patients except local warm feeling.

    Full Text Available Lauren L Levy, Jason J Emer Department of Dermatology, Mount Sinai School of Medicine, New York, NY, USA Abstract: Hair loss is a commonly encountered problem in clinical practice, with men presenting with a distinctive pattern involving hairline recession and vertex balding (Norwood-Hamilton classification and women exhibiting diffuse hair thinning over the crown (increased part width and sparing of the frontal hairline (Ludwig classification. Female pattern hair loss has a strikingly overwhelming psychological effect; thus, successful treatments are necessary. Difficulty lies in successful treatment interventions, as only two medications – minoxidil and finasteride – are approved for the treatment of androgenetic alopecia, and these medications offer mediocre results, lack of a permanent cure, and potential complications. Hair transplantation is the only current successful permanent option, and it requires surgical procedures. Several other medical options, such as antiandrogens (eg, spironolactone, oral contraceptives, cyproterone, flutamide, dutasteride, prostaglandin analogs (eg, bimatoprost, latanoprost, and ketoconazole are reported to be beneficial. Laser and light therapies have also become popular despite the lack of a profound benefit. Management of expectations is crucial, and the aim of therapy, given the current therapeutic options, is to slow or stop disease progression with contentment despite patient expectations of permanent hair regrowth. This article reviews current perspectives on therapeutic options for female pattern hair loss.

    Full Text Available Forty patients suffering from androgenetic alopecia were given 3 to 4 sittings of hair transplantation at an interval of 4 to 6 weeks each. Only patients of type III, type III(vertex and type IV baldness were operated. Twenty patients, six of type III, six of type III(vertex and eight of type IV baldness were advised to use minoxidil 2% locally at the recipient area in the dose of 1 ml applied twice daily. Twenty patients of similar types of baldness were advised to just shampoo their hair daily without using topical minoxidil. Percentage of response was compared between the two groups. Minoxidil did not play any role in the percentage of hair survival before and after transplantation in androgenetic alopecia. However in 60percent grafts of patients who had used topical minoxidil, there was no initial postoperative hair shedding.

    Full Text Available Alopecia areata (AA is a common form of non-scarring hair loss of scalp and/or body. Genetic predisposition, autoimmunity, and environmental factors play a major role in the etiopathogenesis of AA. Patchy AA is the most common form. Atopy and autoimmune thyroiditis are most common associated conditions. Peribulbar and intrabulbar lymphocytic inflammatory infiltrate resembling "swarm of bees" is characteristic on histopathology. Treatment is mainly focused to contain the disease activity. Corticosteroids are the preferred treatments in form of topical, intralesional, or systemic therapy. Camouflage in the form of wigs may be an alternative option in refractory cases.

    Various nonfollicular scalp conditions can cause secondary scarring or permanent alopecia. Possible causes are congenital defects, trauma, inflammatory conditions, infections, and neoplasms (rarely drugs). Associated signs and symptoms and other diagnostic procedures such as histopathology may aid in the diagnosis. Detection of the underlying disorder may be difficult in end-stage lesions. Treatment is specific for active conditions. Surgery and hair transplantation are options for localized scars.

    A 15-year-old spayed female domestic shorthair cat presented with alopecia associated with hepatocellular carcinoma. Clinical signs, which had commenced 6 months previously, included loss of appetite, loss of weight, and depression. As reported by the owner, the cat developed alopecia a week before referral. The hair loss was localized to the ventral aspect of the thorax and abdomen, medial aspect of front and hind limbs, and ventral aspect of the tail, and was associated with histological features consistent with paraneoplastic alopecia. At necropsy, multiple hepatic nodules were observed, and subsequent histopathological investigation showed cords and sheets of hepatocyte-like neoplastic cells positive for the hepatocyte marker (Hep Par 1), thereby demonstrating the hepatocellular origin of the tumour, which was diagnosed as a hepatocellular carcinoma. This is the first report of feline paraneoplastic alopecia associated with hepatocellular carcinoma confirmed by the Hep Par 1 marker.

AA is clinically heterogenous, and its natural history is unpredictable. There is no preventative therapy or cure.Objective: The objective of this study is to provide an evidence-based systematic review on the epidemiology and the burden of AA.Methods and selection criteria: A search was conducted of the published, peer-reviewed literature via PubMed, Embase, and Web of Science. Studies published in English within the last 51 years that measured AA’s incidence, prevalence, distribution, disability-adjusted life years (DALYs, quality of life, and associated psychiatric and medical comorbidities were included. Two authors assessed studies and extracted the data.Results: The lifetime incidence of AA is approximately 2% worldwide. Both formal population studies found no sex predominance. First onset is most common in the third and fourth decades of life but may occur at any age. An earlier age of first onset corresponds with an increased lifetime risk of extensive disease. Global DALYs for AA were calculated at 1,332,800 in 2010. AA patients are at risk for depression and anxiety, atopy, vitiligo, thyroid disease, and other autoimmune conditions.Conclusion: AA is the most prevalent autoimmune disorder and the second most prevalent hair loss disorder after androgenetic alopecia, and the lifetime risk in the global population is approximately 2%. AA is associated with psychiatric and medical comorbidities including depression, anxiety, and several autoimmune disorders, and an increased global burden of disease.Keywords: hair loss, hair, prevalence, incidence, burden of disease

    There is neither a cure for alopecia areata (AA) nor any universally proven therapy that induces and sustains remission in patients afflicted with this autoimmune disease. AA is characterized as a nonscarring alopecia which affects children and adults. It can be relatively easy to treat when the disease is patchy and limited; but when children and adults present with long standing extensive scalp and body hair loss, successful management can be challenging. Of the treatment choices available, physicians and midlevel providers usually select a cost-effective treatment approach based on disease duration, disease activity, age of the patient, and disease extent. In this manuscript, the clinical presentation, epidemiology, pathophysiology, plus current and evolving treatments for AA will be reviewed.

    Focal or generalized alopecia is defined as hair loss affecting the ventral, lateral, perineal, and dorsal aspects of the trunk of the cat, usually in a symmetric pattern. This may be attributable to failure of hair coat production, excess loss of hair due to self trauma, or excess shedding of whole hairs. Self trauma is the most common cause of hair loss and is associated particularly with flea allergy dermatitis. Other causes of hair loss are reviewed.

    2008-01-01

    A progressive scarring alopecia of the central scalp is commonly seen in young to middle-aged females of African descent. It usually starts at the vertex or mid top of the scalp and gradually spreads centrifugally, hence, the unifying term of central centrifugal cicatricial alopecia. The clinical pattern is suggestive of female pattern alopecia, but a lack of follicular pores indicative of scarring is present. It can progress for years before slowly burning out. The etiology is unknown but genetic factors may be important. It is often associated with a history of traumatic hairstyling involving heat, traction, and chemicals. However, most patients of African descent without this disorder have similar styling habits. Nonetheless, avoidance of physical and chemical trauma to the scalp hair, the use of suitable shampoos and conditioners, and the encouragement of natural hairstyles may be helpful. Any infection should be treated. Topical or intralesional corticosteroids and systemic antibiotics may be useful and topical minoxidil should be tried with the hope of preventing further scarring and encouraging regrowth of recovering follicles. Current research into the etiology of this disorder will help to foster much-needed clinical trials of therapeutic agents.

    Full Text Available A case of alopecia areata followed by relapsing polychondritis is presented. Similar cases from the literature are reviewed and speculation about the relationship of these diseases is offered. Although the occurrence of these diseases together could be coincidental, an association seems immunologically plausible. Thus, relapsing polychondritis might be an unusual systemic manifestation of alopecia areata.

Case Report: We describe an interesting alopecia case with amalgamated clinical, histologic and immunopathologic features of scarring and non-scarring alopecia. Specifically, the case displays combined features of alopecia areata (AA and of central centrifugal cicatricial alopecia (CCCA. A 36 year old female presented with symmetric, round, patchy hair loss on her scalp. Methods: Biopsies for hematoxylin and eosin (H&E examination, as well as for special stains, direct immunofluorescence (DIF and immunohistochemistry (IHC were performed. Results: The H&E biopsy revealed focally diminished hair follicular units, and sebaceous gland damage. Perifollicular concentric fibrosis was confirmed by Verhoeff elastin special staining. Antibodies to micelles were noted. Positive IHC staining for CD4, CD8, CD45 and multiple proteases and protease inhibitors was noted around selected follicular unit remnants. Conclusion: We present a rare alopecia, combining histologic features of CCCA with additional, selected immunologic features of AA.

    Full Text Available A middle aged woman developed matting of the hairs of the scalp following use of a home made shampoo that contained leaves of Hibiscus rosasiensis. The entangled and matted hair mass in the occipital region pulled hairs of the vertex region of the scalp, resulting in a patch of traction alopecia. Release of tension on the hairs by cutting them with scissors prevented further extension of alopecia.

    Solatium tuberosum L. diploid strains with superior androgenetic capacity have been selected for from androgenetic progenies of unselected diploid material. The paper also demonstrates that the use of a liquid medium for culturing potato anthers, instead of the conventional solid agar plates, improves the yield of androgenetic embryoids. The new method, associated with two successive cycles of selection for superior androgenetic response, allows the induction and regeneration of microspore derived plants on a large scale. The best genotype (clone 21 in this paper) regenerates androgenetic plants with a frequency around 30 per each anther plated. Over 80% of the regenerated plants are diploid. It is suggested that the androgenetic embryoids mainly originate from unreduced microspores by a mechanism which maintains a heterozygous or a partly heterozygous genetic situation.

    Human embryonic stem cells (hESCs) have long been considered as a promising source for cell replacement therapy. However, one major obstacle for the use of these cells is immune compatibility. Histocompatible human parthenogenetic ESCs have been reported as a new method for generating human leukocyte antigen (HLA)-matched hESCs. To further investigate the possibility of obtaining histocompatible stem cells from uniparental embryos, we tried to produce androgenetic haploid human embryos by injecting a single spermatozoon into enucleated human oocyte, and establish human androgenetic embryonic stem (hAGES) cell lines from androgenetic embryos. In the present study, a diploid hAGES cell line has been established, which exhibits typical features of human ESCs, including the expression of pluripotency markers, having differentiation potential in vitro and in vivo, and stable propagation in an undifferentiated state (>P40). Bisulfite sequencing of the H19, Snrpn, Meg3, and Kv imprinting control regions suggested that hAGES cells maintained to a certain extent a sperm methylation pattern. Genome-wide single nucleotide polymorphism, short tandem repeat, and HLA analyses revealed that the hAGES cell genome was highly homozygous. These results suggest that hAGES cells from spermatozoon could serve as a useful tool for studying the mechanisms underlying genomic imprinting in humans. It might also be used as a potential resource for cell replacement therapy as parthenogenetic stem cells.

    Chemotherapy-induced alopecia (CIA) is one of the most distressing side effects of antineoplastic chemotherapy for which there is no effective interventional approach. A low-level laser (LLL) device, the HairMax LaserComb®, has been cleared by the FDA to treat androgenetic alopecia. Its effects may be extended to other settings; we have demonstrated that LaserComb treatment induced hair regrowth in a mouse model for alopecia areata. In the current study, we tested whether LLL treatment could promote hair regrowth in a rat model for CIA. Chemotherapy agents cyclophosphamide, etoposide, or a combination of cyclophosphamide and doxorubicin were administered in young rats to induce alopecia, with or without LLL treatment. As expected, 7-10 days later, all the rats developed full body alopecia. However, rats receiving laser treatment regrew hair 5 days earlier than rats receiving chemotherapy alone or sham laser treatment (with the laser turned off). The accelerated hair regrowth in laser-treated rats was confirmed by histology. In addition, LLL treatment did not provide local protection to subcutaneously injected Shay chloroleukemic cells. Taken together, our results demonstrated that LLL treatment significantly accelerated hair regrowth after CIA without compromising the efficacy of chemotherapy in our rat model. Our results suggest that LLL should be explored for the treatment of CIA in clinical trials because LLL devices for home use (such as the HairMax LaserComb®) provide a user-friendly and noninvasive approach that could be translated to increased patient compliance and improved efficacy.

    The effect of androgen receptor transcriptional activation by RU58841, a nonsteroidal anti-androgen, was studied in the human prostate cancer PC3 cell line by cotransfection with wild-type androgen receptor (wt AR) and an androgen-responsive reporter (MMTV-ARE-CAT) construct. Anti-and rogens, hydroxyflutamide, and Casodex, and the antiestrogen, genistein, were studied in parallel for comparison with RU58841. The wt AR was activated only by the androgen dihydrotestosterone (DHT). Neither the anti-androgens nor antiestrogen can enhance AR transcriptional activity at 10(-11)-10(-7)M in PC3 cells. Hydroxyflutamide, RU58841, and Casodex, but not genistein, displayed competitively suppressive effects on DHT activation of wt AR. The potency of RU58841 was comparable to that of hydroxyflutamide. From this result, topical application of RU58841, which is considered to be a potential therapy for skin diseases, may induce systemic side effects. However, RU58841, on topical application, revealed a potent increase in density, thickening, and length of hair in the macaque model of androgenetic alopecia, whereas no systemic effects were detected. Together our results suggest that RU58841 may have potent antagonism to the wt AR and could be considered as a topically applied active anti-androgen for the treatment of androgen-dependent skin disorders, such as acne, androgenetic alopecia, and hirsutism.

    A 13-year-old female neutered domestic longhaired cat was presented with a five-month history of progressive weight loss and bilaterally symmetrical alopecia of the ventrum, limbs and perineum. The alopecic skin had a shiny appearance and hair in the non-alopecic areas was easily epilated. Fine needle aspirate cytology of a palpable cranial abdominal mass revealed it to be of epithelial or glandular origin. A pancreatic mass was excised by left pancreatectomy during exploratory laparotomy, and histopathology and skin biopsies confirmed a diagnosis of pancreatic carcinoma with concurrent paraneoplastic alopecia. No evidence of metastases was found on liver and lymph node biopsies. At re-examination 10 weeks after surgery, the hair had fully regrown. Skin signs recurred after 18 weeks and metastatic spread of the tumour was confirmed on postmortem examination. This case confirms that paraneoplastic alopecia associated with internal malignancies is a potentially reversible process if the internal neoplasm is excised.

    Full Text Available Ichtiyosis follicularis, alopecia and photophobia (IFAP syndrome is a rare congenital ectodermal syndrome with X-linked inheritance. It occurs as a result of missense mutation in chromosome Xp22.11-Xp22.13 locus of MBTPS2 gene. It usually affects men and family history is always negative. Ichtiyosis follicularis and alopecia starts with birth. Photophobia and eye symptoms begin in early infancy or childhood. Other manifestations of the syndrome include short stature, mental retardation and seizures. There are no spesific histopathological findings specific for ichtyosis follicularis. A 29 years old male patient was admitted to outpatient clinic. Dermatological examination revealed keratosis pilaris localized to scalp, extremities and anterolateral of the body. Patient had xerosis, diffuse alopecia and prominent folicular appereance. Eye examination revealed cataracts and vision loss. These findings led us to IFAP syndrome diagnosis. The patient is presented for the rarity of the syndrome in the literature.

    Full Text Available Background and Design: Alopecia areata is a chronic inflammatory disease characterized by sudden hair loss. Existing evidence suggests that alopecia areata may be associated with personality traits altering the susceptibility to stress and psychiatric conditions associated with stress. The aim of this study was to compare the intensity of depressive and anxiety symptoms and the level of alexithymia in patients with alopecia areata and healthy control subjects.Materials and methods: Fifty patients with the diagnosis of alopecia areata and 30 healthy volunteers were compared in terms of scores of Beck depression inventory, Beck anxiety inventory, and Toronto alexithymia scale.Results: There were no statistically significant differences between alopecia areata cases and healthy controls regarding intensity of anxiety and level of alexythimia (p=0.053 and p=0.120, respectively. The intensity of depressive symptoms exhibited by alopecia areata patients was found to be significantly higher than that in healthy controls (p=0.010 and there was no statistically significant relationship between intensity of depressive symptoms and duration of the current alopecia areata episode (p=0.873.Conclusion: It is suggested that psychiatric evaluation should also be performed in all alopecia areata cases during the clinical follow-up period.

    A 16-year-old boy with Down syndrome and alopecia universalis had dystrophy of all nails. A presumptive diagnosis of tinea unguium, common in persons with Down syndrome, had been made nine years earlier. Despite antifungal therapy, the condition of the nails worsened. We were unable to detect fungi, and believe that his nail changes are most consistent with alopecia-associated trachyonychia (formerly 20-nail dystrophy), a condition not previously reported in persons with Down syndrome.

    Full Text Available The study was undertaken with the aim of evaluating the effect of associated atopy on severity and age at onset of alopecia areata in north Indians. Presence of atopy was elicited by detailed history, examination and intracutaneous tests. Chisquare test was carried out to evaluate statistical significance. One hundred patients (76 males and 24 females with alopecia areata were evaluated. Historical evidence of atopywas present in 50 including patients alone (23, patients and first degree relatives (11 and first degree relatives alone (16. Intracutaneous tests were positive in 23 out of 50 patients tested randomly. There was a trend towards increasing frequency of severe alopecia as evidence of atopy became stronger e.g. both patient and first degree relatives with atopy or positive intracutaneous test but the results did not attain statistical significance. Similarly the age at onset and duration of alopecia areata was not significantly related to the presence of atopy. It is concluded that in north Indians with alopecia areata, the presence of atopy is not significantly associated with severe alopecia or onset at younger age.

    Alopecia is a common clinical presentation of systemic lupus erythematosus (SLE). There are various types of alopecia in SLE, such as lupus hair, non-scarring patchy alopecia, diffuse telogen effluvium and patchy scarring alopecia in discoid lupus erythematosus (DLE). These types of alopecia differ from each other in clinical and histopathological manifestations. Alopecia in patients with SLE may be correlated to the disease activity. The pathogenesis of alopecia in SLE is not fully understood, and may be associated with the changes in local microenvironment induced by autoimmune inflammation and vasculitis, hair nutrient deficiency and disturbances of hair follicle cycle.%脱发是SLE常见的临床表现之一。SLE脱发可表现为多种类型,如狼疮发、非瘢痕性斑状脱发、弥漫性休止期脱发、盘状红斑狼疮型脱发等,不同类型的脱发在临床表现和组织病理学方面有其各自的特点。SLE脱发与疾病活动性有一定的相关性。目前SLE脱发的发病机制尚未明确,自身免疫性炎症和血管炎造成的局部微环境的改变、毛发营养不良和毛囊周期失调均有可能参与其中。

    Squaric acid dibutylester (SADBE) is a commonly used contact sensitizer in immunotherapy for alopecia areata (AA). Severe contact dermatitis is induced by the currently high recommended sensitization dose of 1%-2% SADBE, often decreasing patient compliance. We assessed a modified immunotherapy for AA using SADBE at a starting concentration of 0.01% without sensitization. After one or two weeks of initial 0.01% SADBE application, the concentration of SADBE was increased gradually to 0.025%, 0.05%, 0.1%, 0.25%, 0.5%, 1% and 2% until the patients felt itching or erythema at the AA lesion site. The modified immunotherapy showed a response rate of 69.4% (25/36), equivalent to conventional immunotherapy using SADBE starting at 1%-2% sensitization. Furthermore, we investigated the combination therapy of SADBE and multiple courses of steroid pulses for AA. The response rate for combination therapy was 73.7% (28/38); however, the group receiving combination therapy showed a significant prevalence of severe AA compared with the group receiving modified immunotherapy only. We reviewed the efficacy and safety of modified immunotherapy without initial sensitization and combination therapy with immunotherapy and multiple courses of pulses for AA.

    Full Text Available Ingrid Herskovitz, Mariya Miteva Department of Dermatology and Cutaneous Surgery, University of Miami L Miller School of Medicine, Miami, FL, USA Abstract: Central centrifugal cicatricial alopecia (CCCA is the most common scarring alopecia among African American women. Data about epidemiology, etiology, genetic inheritance, and management are scarce and come from individual reports or small series. CCCA has been associated with hot combing and traumatic hair styling for years; however, studies fail to confirm it as the sole etiologic factor. It has been shown in a small series that CCCA can be inherited in an autosomal dominant fashion, with a partial penetrance and a strong modifying effect of hairstyling and sex. CCCA presents clinically as a central area of progressive irreversible hair loss that expands to the periphery. A patchy form has also been described. Dermoscopy is helpful to identify the optimal site for the biopsy, which establishes the diagnosis. Well-designed randomized controlled trials are needed to discover the optimal management. At this point, patients are advised to avoid traction and chemical treatments; topical and intralesional steroids, calcineurin inhibitors, and minoxidil can be helpful in halting the progression.

    Full Text Available Background and Design: Lichen planopilaris (LPP is a type of cicatricial alopecia characterized by autoreactive lymphocytic destruction of the hair follicle. We aimed to evaluate the demographic, clinical and histopathological features, and treatment outcomes of patients with LPP. Materials and Methods: Medical reports of 25 patients, who have been diagnosed with LPP according to the clinical and histopathological findings between January 2006 and June 2012, were retrospectively reviewed. The transverse and vertical sections of scalp biopsy specimens were re-evaluated by a pathologist, and the findings were noted. Results: Of the 25 patients, 18 were female and 7 were male, the mean age was 49.8±12.4 years. Eighteen patients had been diagnosed with classic LPP and 7 patients with frontal fibrosing alopecia (FFA. The alopecia has begun in postmenopausal period in 5 patients with FFA. Alopecia was associated with pruritus, pain and/or burning in 19 patients. Extra-scalp involvement was observed in 11 patients. The most common clinical findings were follicular hyperkeratosis (92%, perifollicular erythema (48%, perifollicular lichenoid papules, and positive hair-pull test (44%. Dermatoscopic examination was performed in 14 patients, and most commonly, absence of follicular openings (100%, perifollicular scales (92.9% and perifollicular erythema (50% were noted. The most common diagnostic histopathological findingsmwere follicular vacuolar and lichenoid degeneration (88% and vacuolar and lichenoid interface changes (56%.

    Full Text Available Radiation-induced alopecia after fluoroscopically guided procedures is becoming more common due to an increasing use of endovascular procedures. It is characterized by geometric shapes of nonscarring alopecia related to the area of radiation. We report a case of a 46-year-old man presenting with asymptomatic, sharply demarcated rectangular, nonscarring alopecic patch on the occipital scalp following cerebral angiography with fistula embolization under fluoroscopy. His presentations were compatible with radiation-induced alopecia. Herein, we also report a novel scalp dermoscopic finding of blue-grey dots in a target pattern around yellow dots and follicles, which we detected in the lesion of radiation-induced alopecia.

    Full Text Available Alopecia areata and vitiligo are autoimmune diseases, both associated with multiple autoimmune comorbidities. Many studies show colocalization of these diseases at the same anatomical site. Here, we have a case where both disorders were reported to present in the same patient. Diphenylcyclopropenone (diphencyprone, DCP is used in the treatment of alopecia areata and may induce vitiligo in some patients. We report on one case of vitiligo that was induced by DCP during therapy for alopecia universalis. Alopecia areata and vitiligo share many susceptibility genes. Follicular melanocyte destruction may represent the link between the two diseases.

In male subjects of alopecia areata, true palmar pattern (TPP was increased in both hypothenar and left interdigital-2 (ID2 areas while in females, TPP were increased in both inter digital area-2 and 3 and left ID4 areas. TPP were reduced in left thenar (Lt. Th.,Lt. ID1, ID3, ID4, Rt. ID2, ID3 and ID4 areas of alopecia areata males and both right and left thenar and hypothenar and right ID4 areas of females. This study reveals deviation in the form of reduction of number of loops and increase in number of whorls and arches in alopecia subjects. Deviation is also observed in a-b ridge count and atd angle. These can be considered as quite useful as a supportive investigation and to some extent knowing the prediction for alopecia areata.

    2016-04-08

    Alopecia areata is an autoimmune dermatological disorder characterised by loss of hair in one or more discrete patches over the scalp. It has been linked to multiple disorders having an autoimmune origin. Like many autoimmune disorders it tends to be more common in females. To date, only five cases have been reported where alopecia has been associated with narcolepsy. Male gender is less commonly affected by alopecia areata. No case of alopecia areata in males has been associated with narcolepsy to the best of our knowledge. The current case represents the first ever-reported case of alopecia areata in a male patient with narcolepsy type 1. This coexistence is most likely the manifestation of a common underlying pathoimmunological mechanism that has not been completely understood, rather than a random association.

    This article presents a short summary of our current knowledge of cicatricial alopecia disease pathogenesis and the hypothetical disease mechanisms that may be involved in scarring alopecia development. Several forms of scarring alopecia likely involve targeted cytotoxic action against hair follicle cells mediated by a folliculocentric inflammation. However, the specific nature of the inflammatory interference in hair follicle growth is open to question. A popular hypothesis of lymphocyte-mediated scarring alopecia development involves autoimmune targeting of hair follicle-specific self-antigens, although there is no direct evidence in support of such a view. Alternative hypotheses focus on defects in sebaceous gland function, destruction of hair follicle stem cells, and interference in the communication between hair follicle mesenchyme and epithelium. Many questions arise from these hypotheses, and addressing them with a systematic research approach may enable significant advances in understanding cicatricial alopecia etiology.

    Central centrifugal cicatricial alopecia (CCCA) is the most common scarring alopecia among African American women. Data about epidemiology, etiology, genetic inheritance, and management are scarce and come from individual reports or small series. CCCA has been associated with hot combing and traumatic hair styling for years; however, studies fail to confirm it as the sole etiologic factor. It has been shown in a small series that CCCA can be inherited in an autosomal dominant fashion, with a partial penetrance and a strong modifying effect of hairstyling and sex. CCCA presents clinically as a central area of progressive irreversible hair loss that expands to the periphery. A patchy form has also been described. Dermoscopy is helpful to identify the optimal site for the biopsy, which establishes the diagnosis. Well-designed randomized controlled trials are needed to discover the optimal management. At this point, patients are advised to avoid traction and chemical treatments; topical and intralesional steroids, calcineurin inhibitors, and minoxidil can be helpful in halting the progression.

    This report describes the antemortem diagnosis and antemortem and postmortem findings of superficial necrolytic dermatitis with hepatopathy (i.e., hepatocutaneous syndrome) in a cat. A 5-year-old Maine coon was evaluated because of a history of pruritic alopecia and liver enzyme elevations. Abdominal ultrasonography revealed a reticular pattern to the hepatic parenchyma. Histopathological findings of the liver were nodular regeneration with bands of vacuolated hepatocytes and bile duct hyperplasia, characteristic of the hepatopathy frequently associated with superficial necrolytic dermatitis. Skin histopathology revealed multifocal parakeratosis, midepidermal spongiosis, and basal cell hyperplasia consistent with superficial necrolytic dermatitis.

    2013-01-01

    The authors sought to investigate androgenic alopecia (AA) utilizing clinical and investigative procedures to establish the pattern of AA in the Indian subcontinent. A total of 35 consecutive women presenting with AA were included. After obtaining informed consent, a detailed history/examination, hair pull test, trichogram, and a scalp biopsy were performed in patients. AA classification was attempted across Ludwig and Norwood guidelines. Of 35 women, 16 had grade I, 10 had grade II, and 1 had grade III Ludwig classification. In addition, 6 other women had Christmas tree baldness: 1 each of fronto-parietal and male pattern baldness. Several investigations including hormonal profile were inconclusive; however, hair pull test and trichogram may be helpful in understanding the sequence in AA in women. AA has infrequently been reported, particularly India and in Asia in general.

    Although the complete picture for alopecia areata (AA) pathogenesis has yet to be determined, recent research has made much progress in our understanding of the disease mechanism. Numerous circumstantial evidence supports the notion that AA is fundamentally a disease mediated by inflammatory cells and may be autoimmune in nature. Recent research has shown the hair-loss phenotype is precipitated predominantly by CD8+ lymphocytes, but the disease mechanism is driven by CD4+ lymphocytes. Although genetic susceptibility is a key contributor to disease development, disease onset and phenotypic presentation are probably modified by complex environmental interplay. On the basis of our current understanding of AA disease pathogenesis, several experimental and theoretical therapeutic approaches might be possible. However, the pathogenetic disease mechanism is particularly robust and the development of a cure for AA will be a significant challenge.

    Full Text Available Frontal fibrosing alopecia (FFA is more common in postmenopausal women, but it can occur in younger women. Some authors consider FFA to be a distinct frontal variant of lichen planopilaris. From a clinical point of view, this relatively uncommon condition is characterized by progressive frontotemporal recession due to inflammatory destruction of hair follicles. Dermoscopy can be very useful, as the differential diagnosis between traction alopecia, alopecia areata, FFA and cicatricial marginal alopecia may be difficult. It is not clear whether or not treatment alters the natural history of the disease – the disease stabilized with time in most of the patients with or without continuing treatment. Here we report a case of a 50-year-old woman with FFA and discuss the relevance of dermoscopy in the differential diagnosis of this disease.

    Alopecia (hair loss) occurs in some nonhuman primates housed in captivity and is of concern to colony managers and veterinarians. Here we review the characteristics, potential causes, and treatments for this condition. Although we focus on nonhuman primates, relevant research on other mammalian species is discussed also, due to the relative paucity of studies on alopecia in the primate literature. We first discuss the cycle of hair growth and explain how this cycle can be disrupted to produce alopecia. Numerous factors may be related to hair loss and range from naturally occurring processes (for example, seasonality, aging) to various biologic dysfunctions, including vitamin and mineral imbalances, endocrine disorders, immunologic diseases, and genetic mutations. We also address bacterial and fungal infections, infestation by parasites, and atopic dermatitis as possible causes of alopecia. Finally, we examine the role of psychogenic factors, such as stress. Depending on the presumed cause of the hair loss, various treatment strategies can be pursued. Alopecia in nonhuman primates is a multifaceted disorder with many potential sources. For this reason, appropriate testing for various disease conditions should be completed before alopecia is considered to be related to stress.

    Abacavir is a nucleoside reverse-transcriptase inhibitor that has been approved for use in combination with other retroviral agents in the treatment of HIV infection. Common adverse reactions include headache, fatigue, nausea, and rash. A fatal hypersensitivity reaction may occur in 5% of patients receiving abacavir; therefore, screening for HLA-B5701 should be performed before starting abacavir. Alopecia areata (AA) is infrequently reported in HIV-infected patients. Certain underlying conditions have been associated with AA, including a decreased CD4:CD8 ratio related to the progression of HIV infection, some opportunistic infections, and syphilis. Several antiretroviral drugs, such as zidovudine, indinavir, indinavir/ritonavir, lopinavir/ritonavir, and atazanavir/ritonavir have been implicated in the development of AA. At present, the occurrence of AA has not been associated with abacavir use. We cannot exclude that the use of abacavir and the development of AA could be coincidental. Nevertheless, patients given abacavir should be monitored for hair loss and the drug discontinued promptly if such signs appear.

  19. Chemotherapy-induced alopecia: advice and support for hair loss.

    Science.gov (United States)

    Roe, Helen

    This article provides insight into the growth cycle of a hair follicle and the potential impact chemotherapy agents can have on this process, which often results in hair loss (alopecia). It explores the psychological consequences of chemotherapy-induced alopecia for an individual as a result of the perceptions of others as well as an individual's perception of his or her self-image. Despite the development of various forms of scalp cooling, chemotherapy-induced alopecia remains a major side effect for patients receiving chemotherapy; however, there have been improvements in wig provision and changing public opinion relating to baldness. Although chemotherapy-induced alopecia affects both males and females and all age groups, this article focuses on the potential impact for patients receiving chemotherapy as a form of treatment for breast cancer. As professionals we need to understand the social significance of hair in relation to a person's outward presentation and social interactions, along with the possible psychological implications of a person losing his or her bodily hair, and not just the head hair. We must aim to minimize the distress alopecia can cause by: ensuring we provide patients with up-to-date verbal and written information to enable them to prepare for losing their hair; helping them to preserve their self-image and minimize the psychological consequences of hair loss while receiving chemotherapy; and preparing them for their hair re-growth following completion of chemotherapy.

    Full Text Available Alopecia areata is hair loss with patchy formation, the most common cause of alopecia nonscarring. Occurred in 1,7 % of Americans aged 50 years. Canoccurs in both sexes, all races and any age. Genetic and immunological factorsplay an important role as a cause of Alopecia areata. The clinical features alopecia areata are round or oval lesions, total baldness, smoothness on the scalpor other parts of the body that has hair. Minoxidil is one of the effective therapyfor Alopecia areata. Known for more than 30 years of minoxidil to stimulate hairgrowth. Minoxidil works on hair follicles, opening the potassium channels, andhave vascular effects that can increase blood flow to hair. Histological studiesshowed that minoxidil therapy may increase the proportion hair follicles in anagenphase and decrease hair follicles at telogen phase. Minoxidil through sulphatmetabolites can open potassium channels, the opening potassium channels canincrease the hair follicles growth. The study of the effects minoxidil on humanepidermal keratinocytes and hair follicles with different culture conditions andmarkers proliferation, found that minoxidil with micro molar concentration canstimulate proliferation both type of cells and all culture condition, whereasminoxidil with milimolar concentration will inhibit cell growth. In addition,several studies have also reported an association minoxidil to vascular effect andstimulating VEGF can promote the increase hair follicle

    Full Text Available Background: There have been few reports on primary cicatricial alopecias (PCR especially from Asia (PCA. Aims: To study the clinical, pathological and dermoscopic characteristics of PCA among Chinese patients. Methods: A retrospective analysis of the clinical data of 59 patients with PCA was conducted and the dermoscopic, pathological, treatment and prognosis characteristics analyzed. Fisher′s Chi-square exact test, Kruskal-Wallis and Spearman rank correlation test were performed. Results: The ratio of neutrophilic to lymphocytic cicatricial alopecias was about 1.3:1 in this group. The most frequent disorder was folliculitis decalvans. Follicular openings were absent on dermoscopy in all cases except alopecia mucinosa. Patulous follicular openings were characterisitc of alopecia mucinosa. After treatment, an increase in short vellus hairs was the earliest feature, while telangiectasia, epidermal scale, follicular hyperkeratosis, pustules and hair diameter diversity gradually decreased or even disappeared. Improvement in the areas of hair loss after treatment was seen more often in discoid lupus erythematosus, folliculitis decalvans and dissecting cellulitis than in patients with classic pseudopelade of Brocq. Nine patients (13.6% relapsed after cessation of therapy. Female patients needed longer treatment times. Long duration, large areas of hair loss and shorter treatment courses were the major factors in relapses. Conclusions: Dermatoscopy provides a rapid, practical and useful aid for the diagnosis of PCA and also to assess disease activity. Patulous follicular openings are a specific dermoscopic sign of alopecia mucinosa. Lichen planopilaris is less common in China than in the West.

    Full Text Available Case summary A 10-year-old male neutered British Shorthair cat was presented with a 6 month history of lethargy, weight loss and alopecia. Clinical examination revealed widespread alopecia of the ventral abdomen and hindlimbs. The skin in these areas was smooth and shiny and hairs could be easily epilated. Spontaneous pruritus was observed. Cytological examination of superficial impression smears showed a severe Malassezia species dermatitis and pyoderma. Ectoparasites could not be detected and no sign of dermatophytosis was visible in trichograms and Wood’s lamp analysis. Abdominal ultrasound found a focally thickened wall of the large intestine and multiple nodules in the liver. Fine-needle aspirates from lymph nodes, liver and altered colonic wall were consistent with an undifferentiated malignant neoplasia. The cat was euthanased at the owners’ request, owing to potential neoplasia with metastatic spread. At necropsy a metastasising carcinoma of the colonic wall was found, as well as a paraneoplastic alopecia. Relevance and novel information Feline paraneoplastic alopecia has been reported in association with pancreatic carcinoma, bile duct carcinoma and hepatocellular carcinoma, as well as with neuroendocrine pancreatic carcinoma and hepatosplenic plasma cell tumour. This is the first reported case of feline paraneoplastic alopecia associated with a colon carcinoma.

    Hereditary vitamin D-resistant rickets (HVDRR) is a rare autosomal recessive disorder caused by mutations in the vitamin D receptor (VDR) gene. We report the case of an infant presenting with alopecia, growth failure, and gross motor developmental delay. Serum biochemistry and skeletal survey were consistent with rickets. After a poor response to standard treatment, genetic testing confirmed a c.147-2A>T novel mutation in the VDR gene consistent with HVDRR. It is important for dermatologists and pediatricians to recognize alopecia as a presenting sign of HVDRR because appropriate treatment leads to better growth and development of the child.

    Alopecia areata is an autoimmune disease characterized by non-scaring hair loss. The onset in over 50-year-old patients is rare and has barely been studied. Cases of this disease have been retrospectively analyzed – according to clinical forms, extension, and associated diseases – to assess alopecia areata characteristics in a group of patients whose disease onset was after the age of 50. 30 patients were studied; a few of them presented with autoimmune-related diseases or family history. The disease onset after the age of 50 seems to have different characteristics from those found in young people. PMID:28099618

    Clinical management of alopecia represents one of the major issues in dermatology. Scalp biopsies are not easily accepted because of the high bleeding and sensitive anatomical area. Trichoscopy is routinely used for diagnosis of alopecia, but in several cases lack to provide sufficient information on the status of the disease. Recently, reflectance confocal microscopy demonstrated its usefulness for the evaluation of several inflammatory skin condition and preliminary reports about alopecia have been proposed in the literature. The aim was to identify the confocal features characterizing scarring and non-scarring alopecia. Reflectance confocal microscopy from 86 patients affected by scarring (28 lichen planopilaris and 9 lupus erythematosus) and non-scarring alopecia (30 androgenic alopecia and 19 alopecia areata), were retrospectively, blinded evaluated. Good concordance between different readers on the confocal criteria has been assessed. Statistical significant features, specific for scarring alopecia and non-scarring alopecia have been identified. In this study, data on reflectance confocal microscopy features useful for the differential diagnosis between scarring and non-scarring alopecia have been identified. Further studies focusing on the use of this non-invasive technique in the therapeutic follow-up and distinction of sub-entities of alopecia are still required.

The skin is also commonly involved, although cutaneous sarcoidosis on the scalp is rare. Two cases of scalp sarcoidosis are reported: the first presented with patchy alopecia, cutaneous sarcoidosis and also systemic disease in a black patient; the second case is related to an uncommon presentation with alopecia as the single cutaneous manifestation in a Caucasian patient with pulmonary sarcoidosis. Scalp sarcoidosis deserves special attention because there is a high incidence of other systemic lesions with this cutaneous manifestation, thus a careful investigation should be performed in these patients.

    2011-01-01

    This article provides information on the phenomenon of alopecia in Japanese macaques, Macaca fuscata, in various environments and proposes a 3-step scoring system for a quantitative assessment of hair loss. Results suggest that alopecia is commonly observed in Japanese macaques, with 20.5% of individuals showing head alopecia and 4.7% showing back alopecia across eight study groups. Alopecia was more commonly observed in adult females (30.8% individuals showing head alopecia and 15.3% showing back alopecia) than in other age-sex classes. Seasonal variation of back alopecia was noted, in particular, individuals with patchy back hair were more frequently observed in winter than in summer. Seasonal variation was not observed in head hair. The distribution of alopecia was also different among study groups. The wild population generally had better hair condition than provisioned populations and captive populations. The present study used a non-invasive alopecia scoring system which can be a useful, rapid and non-invasive tool to monitor animal health and well-being at a population level.

    A study aimed at determining the histopathologic appearance of chromoblastomycotic lesions was undertaken. Biopsies from 26 patients with the disease were examined. It was found that 23 cases (88.46%) exhibited the organized mixed mycotic granuloma - OMMA -, a granuloma modified by the presence polymorphonuclear neutrophils - PMN's. An equal proportion of cases exhibited pseudoepitheliomatous hyperplasia, with the epithelium playing an important role in the transepidermic elimination of the fungus. Healing of the lesions took place by fibrosis which was observed in 21 (80.77%) patients; this type of reaction was more common in the deeper areas of the dermis.

    Frontal fibrosing alopecia is a distinctive form of scarring alopecia considered to be a clinical variant of lichen planopilaris. It predominantly occurs in postmenopausal women and has a slowly progressive course. It was first described by Kossard in 1994. Since then the number of reported cases has increased significantly. Coexistence of frontal fibrosing alopecia and autoimmune disorders - such as discoid erythematosus lupus and Sjögren's syndrome - may suggest a common pathogenic background among the diseases.

    Full Text Available Alopecia areata (AA is an autoimmune disease typified by nonscarring hair loss with a variable clinical course. In this study, we conducted whole genome gene expression analysis of 96 human scalp skin biopsy specimens from AA or normal control subjects. Based on gene expression profiling, samples formed distinct clusters based on the presence or absence of disease as well as disease phenotype (patchy disease compared with alopecia totalis or universalis. Differential gene expression analysis allowed us to robustly demonstrate graded immune activity in samples of increasing phenotypic severity and generate a quantitative gene expression scoring system that classified samples based on interferon and cytotoxic T lymphocyte immune signatures critical for disease pathogenesis.

  2. DHEA and frontal fibrosing alopecia: molecular and physiopathological mechanisms*

    2016-01-01

    The transforming growth factor-beta 1 (TGFβ1) promotes fibrosis, differentiating epithelial cells and quiescent fibroblasts into myofibroblasts and increasing expression of extracellular matrix. Recent investigations have shown that PPAR (peroxisome proliferator-activated receptor*) is a negative regulator of fibrotic events induced by TGFβ1. Dehydroepiandrosterone (DHEA) is an immunomodulatory hormone essential for PPAR functions, and is reduced in some processes characterized by fibrosis. Although scarring alopecia characteristically develops in the female biological period in which occurs decreased production of DHEA, there are no data in the literature relating its reduction to fibrogenic process of this condition. This article aims to review the fibrogenic activity of TGFβ1, its control by PPAR and its relation with DHEA in the frontal fibrosing alopecia. PMID:28099600

    Acne, androgenogenetic alopecia, hyperseborrhea and hirsutism may result from hyperandrogenism in women. This may be peripheral "idiopathic" hyperandrogenism due to cutaneous metabolism of steroids, but in some cases hyperandrogenism is due to abnormal production or input of steroids with androgenic activity (hyperplasia, endocrine tumors, cysts, consumption of progestogens or other hormones with androgenic activity, menopause...). An assessment is useful only in cases of acne or alopecia if they are accompanied by other signs of peripheral hyperandrogenism and/or disturbed menstruation. The treatment is based on the administration of an anti-androgen (in France, usually cyproterone acetate), combined with other local or systemic treatments for the problem, depending on the age, dermatological signs and context.

    Alopecia areata (AA) is a nonscarring hair loss disorder with a 2% lifetime risk. Most patients are below 30 years old. Clinical types include patchy AA, AA reticularis, diffuse AA, AA ophiasis, AA sisiapho, and perinevoid AA. Besides scalp and body hair, the eyebrows, eyelashes, and nails can be affected. The disorder may be circumscribed, total (scalp hair loss), and universal (loss of all hairs). Atopy, autoimmune thyroid disease, and vitiligo are more commonly associated. The course of the disease is unpredictable. However, early, long-lasting, and severe cases have a less favorable prognosis. The clinical diagnosis is made by the aspect of hairless patches with a normal skin and preserved follicular ostia. Exclamations mark hairs and a positive pull test signal activity. Dermoscopy may reveal yellow dots. White hairs may be spared; initial regrowth may also be nonpigmented. The differential diagnosis includes trichotillomania, scarring alopecia, and other nonscarring hair loss disorders such as tinea capitis and syphilis.

    Androgen excess disorders--acne, alopecia, and hirsutism--can be treated effectively with endocrine therapy such as androgen receptor blockers or antagonists, or with androgen suppression. Spironolactone, estrogen, and dexamethasone are considered the most effective approaches to treatment. Whatever the modality, careful planning is key to success, with recognition that response rates vary from patient to patient. A treatment regimen generally continues for at least 2 years.

    Introduction Hair loss or alopecia affects the majority of the population at some time in their life, and increasingly, sufferers are demanding treatment. Three main types of alopecia (androgenic [AGA], areata [AA] and chemotherapy-induced [CIA]) are very different, and have their own laboratory models and separate drug-discovery efforts. Areas covered In this article, the authors review the biology of hair, hair follicle (HF) cycling, stem cells and signaling pathways. AGA, due to dihydrotesterone, is treated by 5-α reductase inhibitors, androgen receptor blockers and ATP-sensitive potassium channel-openers. AA, which involves attack by CD8+NK group 2D-positive (NKG2D+) T cells, is treated with immunosuppressives, biologics and JAK inhibitors. Meanwhile, CIA is treated by apoptosis inhibitors, cytokines and topical immunotherapy. Expert opinion The desire to treat alopecia with an easy topical preparation is expected to grow with time, particularly with an increasing aging population. The discovery of epidermal stem cells in the HF has given new life to the search for a cure for baldness. Drug discovery efforts are being increasingly centered on these stem cells, boosting the hair cycle and reversing miniaturization of HF. Better understanding of the molecular mechanisms underlying the immune attack in AA will yield new drugs. New discoveries in HF neogenesis and low-level light therapy will undoubtedly have a role to play. PMID:25662177

    Full Text Available Three cases with single lesion of Alopecia mucinosa (follicular mucinosis were treated with antileprosy treatment and showed rapid and complete resolution of the lesions with no recurrence on extended follow-up. Two children, a boy aged 14 years and a girl aged 12 years presented themselves, each, with a single hypopigmented, hypoesthetic patch on the face. Clinically leprosy was suspected, however, skin biopsy from both patients revealed follicular mucinosis as the only pathological finding, without any granulomas. Based on clinical suspicion both were started on multi drug therapy (MDT for leprosy with complete resolution of the lesions. The third case, male, aged 22 years presented with a single erythematous, hypoesthetic plaque on the forehead.This lesion had been diagnosed as follicular mucinosis with folliculo-tropic mycosis fungoides, in the USA. He too responded completely within 3 months with rifampicin, ofloxacin, minocycline (ROM treatment, which was given once monthly for a total of 6 months and remains free of disease since the past 1 year. Follicular mucinosis as the only pathology may be seen in facial lesions of clinically suspected leprosy in children and young adults. Based on histological findings these cannot be diagnosed as leprosy and will be considered as Alopecia mucinosa. These lesions, however, are always single and show rapid and complete response to antileprosy treatment. The authors suggest that in regions endemic for leprosy, such as India, single lesion Alopecia mucinosa on the face in children and young adults should be given antileprosy treatment.

    Full Text Available We describe here a rare case of variant of mycosis fungoides (MF: ichthyosiform MF with alopecia and atypical membranous nephropathy. The diagnosis was made based on the following findings: generalized ichthyosis-like eruption, alopecia, enlarged superficial lymph nodes, proteinuria, and hematuria, the histological features of the skin biopsy from both ichthyotic and alopecic lesions with immunohistochemical staining, and the renal biopsy examination with immunofluorescence. The histological examination of ichthyotic and alopecic lesions displayed a predominant infiltration of atypical lymphocytes in the upper dermis with the characteristics of epidermotropism and folliculotropism. Immunohistochemical studies demonstrated that most infiltrated atypical lymphocytes were CD3, CD4, and CD45RO positive, whereas negative for CD5, CD7, CD20, CD30, and CD56. A renal biopsy examination revealed atypical membranous nephropathy with deposition of immunoglobulin G (IgG, IgM, IgA, C1q, and C3. In this case atypical membranous nephropathy was involved, which is very uncommon and has never been presented in the literature to date. Although ichthyosiform MF usually features a relatively favorable course, diffuse alopecia and the renal involvement in this case might indicate aggressive disease and poor prognosis.

    2011-09-01

    Full Text Available Psoriasis is a common, chronic, relapsing, papulo-squamous dermatitis, with overlying silvery scales. The scalp, sacral region, and extensor surfaces of extremity are commonly involved, even if flexural and intertriginous areas may be affected in the so-called “inverse psoriasis”. Involvement of nails is frequent. Oral lesions (geographic stomatitis and/or glossitis are commonly described. 5-8% of psoriatic patients develop arthritis. Interphalangeal joints are characteristically involved, but large joints are also affected. From a histological point of view, psoriasis is a dynamic dermatosis that changes during the evolution of an individual lesion; we can classify it in an early stage, advanced stage, and later lesions. Lesions are usually diagnostic only in early stages or near the margin of advancing plaques. Munro microabscesses and Kogoj micropustoles are diagnostic clues of psoriasis, but they aren’t always present. All other features can be found in numerous eczematous dermatitis.

Occurred in 1,7 % of Americans aged 50 years. Can occurs in both sexes, all races and any age. Genetic and immunological factors play an important role as a cause of Alopecia areata. The clinical features alopecia areata are round or oval lesions, total baldness, smoothness on the scalp or other parts of the body that has hair. Minoxidil is one of the effective therapy for Alopecia areata. Known for more than 30 years of minoxidil to stimulate hair growth. Minoxidil works on hair follicles, opening the potassium channels, and have vascular effects that can increase blood flow to hair. Histological studies showed that minoxidil therapy may increase the proportion hair follicles in anagen phase and decrease hair follicles at telogen phase. Minoxidil through sulphat metabolites can open potassium channels, the opening potassium channels can increase the hair follicles growth. The study of the effects minoxidil on human epidermal keratinocytes and hair follicles with different culture conditions and markers proliferation, found that minoxidil with micro molar concentration can stimulate proliferation both type of cells and all culture condition, whereas minoxidil with milimolar concentration will inhibit cell growth.

    Menisci fulfill many functions within the complex biomechanics of the knee joint. In the case of meniscus lesions, sparing arthroscopic resections and operative refixation are the treatments of choice. With regard to diagnostics, this means that in general terms, the histopathologic diagnostics are carried out on detached meniscus fragments of between 5 mm and 2 cm in size. An experienced pathologist's knowledge of physiologically possible cellular and fibrous histological meniscus damage, as opposed to nonphysiological change regarded as normal with respect to age, is essential during a diagnostic meniscus evaluation. The clinician expects clear statements from the pathologist regarding the severity of previous or secondary degenerative meniscus damage, the age and type of traumatic tears, and appraisal of the relationship between trauma and meniscus damage from an insurance point of view. Close cooperation between the clinician and the pathologist allows for fast and unambiguous correlation of anamnesis, the clinical picture, and morphological reporting so that cases involving insurance problems - which are numerous, often long-term, and often unsatisfactory - can be clarified quickly.

    2014-02-01

    This review focuses on recent changes in the clinical, pathogenetic and therapeutic developments with regards to Alopecia Areata. Some new clinical forms and some phenomena have been described for the first time in recent years. Several phenomena previously observed such as the Renbok, the Koebner and the possibility that an exclamation mark hair can resume its physiological growth have been confirmed. The pathogenetic role of cytotoxic cells is increasingly evident, as well as the deficit of cells and the factors regulating the autoimmune response. The concept of immune privilege of the hair follicle has had further confirmation and have been identified some of the molecular mechanisms such as the expression of the receptors for killer lymphocytes on the trichokeratinocytes of the Outer Root Sheat. There is a renewed interest on the possible role of mast cell as a key element in the acute and chronic phases of the disease. New therapies are focused on the inhibition of the killer cells directed against antigens not yet fully specified of the hair follicle and on the restoration of the immune privilege of this structure. Alopecia Areata is a disease with high emotional impact, able to reduce the quality of life of patients and their family entourage. It is often frustrating for those affected and for the therapists due to its evolution quite unpredictable and the mixed response to the few validated therapies. Investment in research originate almost exclusively from voluntary associations of patients, which need to be known and supported.

    Full Text Available Background: Alopecia areata (AA is a common, recurrent, autoimmune hair disorder. It has been found that vitamin D deficiency is associated with many autoimmune diseases. Aims: The current study aimed to estimate serum levels of 25-hydroxy vitamin D in patients with AA. Materials and Methods: This case–control study included 60 patients with AA and 60 age, gender, skin phototype, and body mass index-matched healthy subjects as a control group. Levels of serum 25-hydroxy vitamin D were estimated using ELISA technique. Results: Serum 25-hydroxy vitamin D levels were significantly lower in AA cases when compared with healthy controls (P < 0.001. The least values were significantly associated with alopecia totalis/universalis compared with patchy AA (P< 0.001 and ophiasis (P = 0.04. Severe AA showed significantly the lowest vitamin D levels compared with cases with mild (P = 0.002 and moderate disease (P = 0.03. A significant inverse correlation was found between 25-hydroxy vitamin D levels and age of the patients (r = −0.38; P = 0.03. There was no significant association between serum 25-hydroxy vitamin D levels and gender, disease duration, disease recurrence, nail affection, duration of sun exposure/day, or positive family history of AA. Conclusion: AA patients have lower levels of 25-hydroxy vitamin D than healthy subjects. More studies are required to assess the value of vitamin D supplementation in the treatment of that disease.

    Lupus erythematosus, especially the discoid form, and lichen planopilaris may be associated and can occur in different topographies (coexistence) or in the same lesion (lupus eythematosus/lichen planus overlap syndrome). Frontal fibrosing alopecia is considered a variant form of lichen planopilaris and is characterized by frontotemporal hairline and eyebrow involvement. Of the association with lupus erythematosus we have only a few descriptions. Hydroxychloroquine and chloroquine diphosphate are antimalarial drugs described as viable treatment options for both diseases, due to an antilymphocytic effect. The association between frontal fibrosing alopecia and lupus erythematosus (discoid or systemic) is reported in this article, showing a progressive alopecia in the frontotemporal hairline despite treatment with hydroxychloroquine.

    Two cats were presented for acute onset of rapidly progressive, bilaterally symmetrical hair loss of the ventrum and limbs. Alopecia occurred within 2 weeks after accidental skin exposure to diesel oil. The remaining hair epilated easily in affected areas. Denuded skin was strikingly dry and had adherent scale. Erythema and demarcation between affected and normal skin by a liquid-line were present in one case. Above this line, the hair could not be removed. The head and the footpads were not involved. Systemic signs were not observed. Both cats made a complete recovery without treatment. Histological examination in one cat revealed severe orthokeratotic hyperkeratosis, mild to moderate acanthosis, follicular keratosis, a moderate dermal infiltrate of mast cells and an almost complete absence of sebaceous glands. If skin contact with diesel oil occurs in a cat, thorough washing of skin and haircoat after soaking in prue vegetable oil is recommended.

    Alopecia areata (AA) is a hair loss disease marked by a focal inflammatory infiltrate of dystrophic anagen stage hair follicles by CD4+ and CD8+ lymphocytes. Although AA is thought to be an autoimmune disorder, definitive proof is lacking. Moreover, characterization of the primary pathogenic mechanisms by which hair loss is induced in AA is limited. In this context, animal models may provide a vital contribution to understanding AA. Recent research using animal models of AA has focused on providing evidence in support of a lymphocyte-mediated pathogenic mechanism consistent with AA as an autoimmune disease. In the future, research with both humans and animal models shall likely concentrate on identifying the primary antigenic epitopes involved in AA and the genetics of AA susceptibility. With a comprehensive understanding of the key elements in AA pathogenesis, new avenues for therapeutic research and intervention will be defined.

  7. Eosinophilic Esophagitis: Another Atopy-Related Alopecia Areata Trigger?

    Ibrahim, Omer; Bergfeld, Wilma F; Piliang, Melissa

    2015-11-01

    Alopecia areata (AA) is associated with atopy in 10-22% of patients, twice the prevalence in the general population. Patients can present with concomitant atopic dermatitis, hay fever, asthma, and even allergies to dust mites. In many cases, severity and flares of these atopic diatheses correlate with severity of AA. Herein we present a patient with AA affected by contemporaneous eosinophilic esophagitis (EoE). EoE is a recently recognized allergic disorder, mediated by eosiniphils and histamine. It is characterized by esophageal dysfunction and intraepithelial microabscesses. We propose that EoE be considered as a condition falling within the realm of atopic diseases, and a potential trigger of AA in affected patients.

    We describe here a 19-year-old Japanese man with an 11-year history of alopecia universalis, who, after the 1st application of a 0.003% diphenylcyclopropenone (DPCP) solution to the whole scalp, developed acute contact dermatitis at the test site, together with widespread severe dermographism. Every 3 weeks, persistence of the severe urticarial reaction and efficacy of treatment were monitored by constant pressure stimuli in a series of pressure tests, and subsequently evaluated by laser Doppler flowmetry (LDF). Although, on pressure tests, the urticarial response was found to significantly improve after starting treatment, erythematous responses continued to appear for nearly 3 months. The persistent course of these side-effects in our patient strongly suggests that precautions must currently be taken in the therapeutic use of potent sensitizers such as DPCP.

    Background: Alopecia areata (AA) is a noncicatricial (nonscarring) alopecia. The association between AA and celiac disease (CD) is debatable. Several studies declare the relationship between AA and CD as measurement of celiac autoantibodies (anti-gliadin IgA and anti-gliadin IgG), but a few studies consider anti-tissue transglutaminase IgA. The aim of this study was to evaluate the frequency distribution of celiac autoantibodies (all of them) in patients with AA compared with controls. Methods: This study is a case–control study. Thirty-five patients entered in each group. Anti-gliadin IgA, anti-gliadin IgG, and anti-tissue transglutaminase IgA were tested in all patients. Samples were examined in ELISA method with binding site's kits, and the result was reported as positive/negative. Finally, the frequency distribution of autoantibodies was examined. Results: The age average did not show a significant difference between two groups (P = 0.62). In addition, there was no significant difference between the two groups based on gender (P = 0.15). The prevalence of antibody in case and control groups was 2.85% and 0%, respectively. There was no significant difference between the two groups (P = 0.31). Conclusions: There may be a relationship between CD and AA, but the absence of statistical association between AA and CD does not mean that there is no relationship between gluten and AA in certain patients. Thus, we have shown here that the biological tests to search for CD do not bring information and proof enough, and it is why we recommend another approach to disclose gluten intolerance in AA patients.

Patient and methods: A 46-year-old patient was referred to the Department of Ophthalmology of Mie University Hospital because of a severe corneal ulcer of the right eye of 6 months' duration. Our initial examination showed a ring-shaped corneal opacity with extensive epithelial defects and nodular scleritis. Cysts of Acanthamoeba were identified in cultures from corneal scrapings, and he was diagnosed with ASK. He was started on antiamoebic treatment, including topical micafungin and chlorhexidine. The corneal ulcer was debrided several times. One month later, he developed necrotizing scleritis, and the cornea suddenly perforated. The eye was enucleated because of severe pain and prepared for histopathological examination. Results: The histopathological examination showed an infiltration of polymorphonuclear leukocytes throughout the corneal stroma and also in the limbal area of the sclera, forming an abscess. Granulation tissue was observed in the anterior sclera close to the ciliary body, but the posterior regions of the eye were not affected by inflammation or tissue destruction. The cysts of Acanthamoeba were observed only in the cornea. Conclusion: Histopathological examination of an eye with severe ASK showed that the inflammation and tissue granulation were present only in the anterior part of eye, and the posterior segment was not affected. Because the inflammation and tissue destruction were confined to the anterior segment, enucleation might not have been necessary if the severe pain was

    Alopecia areata (AA) is believed to be a cell-mediated autoimmune hair loss disease. Both CD4 and cytotoxic CD8 T cells (CTLs) are important for the onset and progression of AA. Hair follicle (HF) keratinocyte and/or melanocyte antigen epitopes are suspected potential targets of autoreactive CTLs, but the specific epitopes have not yet been identified. We investigated the potential for a panel of known epitopes, expressed by HF keratinocytes and melanocytes, to induce activation of CTL populations in peripheral blood mononuclear cells. Specific synthetic epitopes derived from HF antigens trichohyalin and tyrosinase-related protein-2 induced significantly higher frequencies of response in AA CTLs compared with healthy controls (IFN-gamma secretion). Apoptosis assays revealed conditioned media from AA peripheral blood mononuclear cells stimulated with trichohyalin peptides elevated the expression of apoptosis markers in primary HF keratinocytes. A cytokine array revealed higher expression of IL-13 and chemokine ligand 5 (CCL5, RANTES) from AA peripheral blood mononuclear cells stimulated with trichohyalin peptides compared with controls. The data indicate that AA affected subjects present with an increased frequency of CTLs responsive to epitopes originating from keratinocytes and melanocytes; the activated CTLs secreted soluble factors that induced apoptosis in HF keratinocytes. Potentially, CTL response to self-antigen epitopes, particularly trichohyalin epitopes, could be a prognostic marker for human AA.

    Full Text Available Background: Alopecia areata (AA is a common, chronic inflammatory disease characterized by nonscarring hair loss on the scalp or any hair-bearing area of the body. Recently, dermoscopy, a noninvasive diagnostic procedure, has been employed for the diagnosis of AA. Aim: To evaluate various dermoscopic patterns in AA and correlate these patterns with the disease activity and severity. Materials and Methods: Dermoscopy was performed on AA patients using DL1 dermoscope (magnification ×10 was used. The dermoscopic patterns recorded were analyzed to identify any correlation with the disease activity and severity. Results: A total of fifty patients of AA were recruited in the study. Female outnumbered males with the ratio being 1.173:1. Mean age of the patients was 25.06 years. Mean duration of disease was 14 months. The most common site involved was scalp (80% and type noted was patchy (84%. Various dermoscopic patterns noted were yellow dots (YD (88%, short vellus hair (66%, black dots (BD (58%, broken hairs (BHs (56%, tapering hair (TH (26%, Coudability hairs (14%, pigtail hair (14%, and Pohl-Pinkus constrictions (2%. Statistically significant correlation was observed between BD, BHs, THs, and disease activity. No significant correlation was found between severity and any of the dermoscopic features. Conclusion: The most common dermoscopic pattern in our study was YD. Presence of BDs, BHs, and THs indicate active disease. Dermoscopic patterns were not affected by severity of the disease.

    Alopecia, accompanied by skin dryness, is one of the distressing side effects often occurring in chemotherapy-treated cancer patients. Little is known of the effects of chemotherapy on sebaceous glands, despite their importance in hair follicle homeostasis. This study investigates sebaceous gland morphology and the response of SZ95 sebaceous gland cell line to doxorubicin (DXR) treatment. The morphology of sebaceous glands during intraperitoneal DXR treatment was investigated by optical and electron microscopy in a 7-day-old rat model and further confirmed in an adult mouse model. Moreover, in vitro studies using the SZ95 sebaceous gland cell line were performed to assess the response of sebocytes to DXR in terms of cell proliferation, apoptosis, and necrosis. DXR treatment induced sebaceous gland regression and occasionally caused their complete disappearance. This observed damage and disappearance preceded DXR-induced hair loss. In vitro experiments using the SZ95 sebaceous gland cell line indicated that DXR treatment induced a differentiation process leading to premature sebocytes apoptosis. Owing to the importance of the sebaceous gland in hair follicle homeostasis, DXR-induced involution of this gland might be related to subsequent hair loss.

    Full Text Available Aim: Alopecia Areata (AA is a type of hair loss that has been considered to have associations with various psychiatric disorders. In this study, we aimed to compare pathological worry levels between patients with AA and healthy controls (HC. Material and Method: Sixty-three patients with AA and 90 HCs were included in the present study after applying inclusion and exclusion criteria. The socio-demographic characteristics, some clinical characteristics, and the scores from the Penn State Worry Questionnaire (PSWQ were compared between groups. Results: The demographic characteristics were found to be similar between groups except for gender. The family history of AA was significantly higher in the AA group. The mean score of PSWQ in the AA group was 44.02 ± 11.59, compared to 39.71 ± 7.77 in the HC group. The mean score of PSWQ was significantly higher in the AA group (t=-3.27, p= 0.001.Discussion: The present study is the first to compare pathological worry between patients with AA and HCs. We suggest that pathological worry should be more thoroughly investigated in patients with AA to improve their quality of life. Also, this can be an effective approach to targeting the patients who may develop anxiety disorder.

    Alopecia areata (AA) is a chronic inflammatory disease that involves the hair follicle. Current evidence indicates that hair follicle inflammation in AA is caused by a T-cell-mediated autoimmune mechanism occurring in genetically predisposed individuals. AA has a reported incidence of 0.1%-0.2%, with a lifetime risk of 1.7%. It has also been found that AA accounts for roughly 2% of new dermatology outpatient cases in the US and the UK, 3.8% of cases in China and 6.7% of cases in Kuwait. Pediatric AA constitutes approximately 20% of all AA cases. AA affects males and females equally. The most common site to be affected is the scalp (90%). The face, eyebrows, eyelashes, beard, underarm hair, and pubic hair may be affected and, sometimes, even the entire body. AA requires combined therapy, involving topical or intralesional corticosteroids, immune therapy with diphenylcyclopropenone, and even psychotherapy. In some cases, treatment consists of simply eliminating the dental infectious process. This case report describes AA of dental origin in a 9-year-old girl, which resolved after management of the dental problem.

    Alopecia areata (AA) is a common disease of hair follicles. Cryotherapy has been employed to stimulate hair regrowth. The current investigation evaluated the efficacy of this method in patchyAA. Forty patients older than 5 years and with 120 recalcitrant patches were enrolled in the study. AA covered less than 50% of the patients' scalps. In each individual, one lesion was treated with N2 jet cryotherapy once a week for a period of 12 weeks, while another lesion was treated with topical 0.05% clobetasol proprionate lotion. All patients were followed from weeks 2 to 16. Thirty-eight of 40 patients completed therapy. The overall response rate of patches was 80% in the cryotherapy group and 91.5% in the clobetasol group. Complete recovery (>95% terminal hair growth) was not obtained in any patient. Results from chi-square test showed no significant difference between improvements in AA in the two groups (reliability 95%). Pearson measurement showed a significant reverse relationship between diameter and duration of patches and the improvement rate in both groups. Liquid nitrogen jet cryotherapy can be a helpful modality in the treatment of AA.

    Full Text Available Background. Alopecia areata (AA has a significant impact on the quality of life and social interaction of those suffering from it. Our aim was to assess the impact of AA on the quality of life. Methods. Fifty patients diagnosed with AA seen in the Department of Dermatology of Hedi Chaker University Hospital, between March 2010 and July 2010, were included. Quality of life was measured by SF 36; severity of AA was measured by SALT. Results. Eighty percent had patchy alopecia with less than 50% involvement, 12% had patchy alopecia with 50–99% involvement, and 8% had alopecia totalis. Compared with the general population, AA patients presented a significantly altered quality of life, found in the global score and in five subscores of the SF-36: mental health, role emotional, social functioning, vitality, and general health. Gender, age, marital status, and severity of alopecia areata had a significant influence on patients’ quality of life. Conclusions. This study indicates that patients with AA experience a poor quality of life, which impacts their overall health. We suggest screening for psychiatric distress. Studies of interventions such as counseling, psychoeducation, and psychotherapeutic interventions to reduce the impact of the disease may be warranted.

As the role of homocysteine (Hcys, folate, and CRP has been considered in some autoimmune diseases. Objectives: To evaluate homocysteine, folate and CRP level in AA. Methods: This study was performed on 29 patients who had AA for at least 6 months affecting more than 20% of scalp, and 32 healthy controls. Levels of serum Hcys, blood high-sensitivity CRP, and RBC folate were measured in all subjects. Results: The mean level of RBC folate was significantly lower in the patient group than that in controls (P < 0.001. Also, the level of RBC folate was significantly lower in patients with extensive forms of disease (alopecia totalis/alopecia universalis in comparison with more localized form (patchy hair loss (P < 0.05. Patients with higher "Severity of Alopecia Total" (SALT score had lower RBC folate, as well. Serum Hcys and blood high-sensitivity CRP levels did not show a significant difference in two groups. Conclusion: Patients with alopecia areata have lower level of RBC folate which is in negative correlation with both severity and extension of AA.

    Full Text Available Seeds of Abrus precatorius L., Fabaceae, are commonly used as purgative, emetic, aphrodisiac and in nervous disorder in traditional and folk medicines. In present study petroleum ether and ethanolic extracts of A. precatorius seeds are evaluated for reversal of androgen (testosterone by i.m route induced alopecia in male albino wistar rats and compared to topical administration of standard antiandrogenic drug finasteride for 21 days. The results were reflected from visual observation and histological study of several skin sections via various parameters as anagen to telogen ratio and follicle density/mm area of skin surface. The animal of group 1 who were treated with only testosterone became alopecic on visual observation. Animals of Group 2, 3 and 4 who were treated with finasteride, petroleum ether and ethanolic extract of seed respectively topically along with testosterone (i.m did not developed alopecia. To investigate the mechanism of observed activity, in vitro experiments were performed. Inhibition of 5α-reductase activity by extracts and finasteride suggest that they reversed androgen induced alopecia by inhibiting conversion of testosterone to dihydrotestosterone (potent androgen responsible for androgenic alopecia. So it may be concluded that petroleum ether and ethanolic extract of A. precatorius seed posses anti androgenic alopecia activity due to inhibition of 5α-reductase enzyme.

    2015-01-01

    Full Text Available Background: Alopecia areata (AA is a chronic non-scarring alopecia that involves the scalp and/or body, and is characterized by patchy areas of hair loss without any signs of clinical inflammation. Various therapies have been proposed for their treatment.But none have been shown to alter the course of the disease. Platelet Rich Plasma (PRP is a volume of autologous plasma that has a high platelet concentration. Growth factors released from platelets may act on stem cells in the bulge area of the follicles, stimulating the development of new follicles and promoting neovascularization. Aim: To evaluate and compare the efficacy of intralesional injection of autologous platelet rich plasma with intralesional injection of triamcinolone acetonide (10mg/ml in the treatment of alopecia areata. Methodology: 74 patients with alopecia areata were allocated into 2 groups and treated with triamcinolone and PRP injections. Treatment outcome was measured by taking into account extent and density of regrowth of hair and was expressed as a percentage of overall growth. Results: Forty eight patients were treated with triamcinolone injections and 26 patients were treated with PRP injections. Patients treated with PRP had an earlier response at the end of 6weeks than patients treated with triamcinolone. However, this difference was statistically insignificant. The overall improvement at the end of 9 weeks was 100% for all patients in both groups. Conclusion: PRP is a safe, simple, biocompatible and effective procedure for the treatment of alopecia areata with efficacy comparable with triamcinolone.

Clinically, patients with alopecia areata may have patchy or confluent hair loss on the scalp or body so we conduct a study to compare the demographic aspects of patient with limited and diffuse type of alopecia areata.Materials and Method: We conducted a descriptive-analyzing study in which 306 patient were chosen. The patients were divided into two groups of diffuse and limited Alopecia. Demographic factors including age, gender, disease onset were compared in two groups. Results: Out of 306 patients, 58.8 % were male and 41.2 % were female. 247 patients (80.7% suffered from limited type and 59 patients (19.2% suffered from diffuse type. The mean age of the onset of involvement in limited group was 21.9±12 yr and 15.8±12 yr in diffuse group. The mean duration of involvement in limited group was 18.7 months and 71 months in diffuse group. Conclusion: Diffuse type alopecia areata starts at lower age and has longer duration. Our study results were similar to the others. Like other studies, thyroid disorders and atopic dermatitis are positively correlative to the severity of disease

    The most commonly reported side effects related to lopinavir/ritonavir are diarrhea, vomiting, headache, nausea, and increased serum triglycerides and cholesterol levels. About 4% of the patients prescribed lopinavir/ritonavir stop taking it because of side effects. Alopecia, generally involving the scalp, has been reported in patients with HIV infection treated with indinavir but not with lopinavir/ritonavir. We present a 62-year-old man with HIV infection, stage B2, who experienced alopecia totalis of his scalp, eyebrows, and eyelashes beginning 18 months after initiating antiretroviral treatment including lopinavir/ritonavir. No hair loss on the arms, legs, and pubic area was observed. Our patient's drug regimen consisted of lopinavir/ritonavir, efavirenz, and stavudine; in addition, the patient was receiving treatment for diabetes with glivenclamide and metformin for the last 3 years. These drugs have not been shown to cause alopecia. Alopecia reversed completely 2 months after substituting nelfinavir for lopinavir/ritonavir without any other change of treatment and his eyelashes and eyebrows grew back as well. To our knowledge, this is the second case of lopinavir/ritonavir-associated alopecia totalis reported in the international literature.

    1998-08-01

    A 13-year-old neutered female domestic shorthaired cat had progressive ventral abdominal alopecia attributed initially to hyperthyroidism. Corrective treatment by unilateral thyroidectomy did not, however, resolve the dermatosis and the alopecia progressed to involve the whole ventral trunk, the lower limbs and the head. Pruritus of the lower limbs was a prominent feature and was associated with the finding of Malassezia on cytology; Malassezia-associated dermatitis was diagnosed. Resolution of pruritus was seen after treatment with oral ketoconazole and a cleansing shampoo to eliminate the yeast, but severe polyphagia, small intestinal diarrhoea and polydipsia developed subsequently and the cat was euthanased. Necropsy revealed an exocrine pancreatic adenocarcinoma with hepatic metastases. The pancreatic, hepatic and dermatological lesions were found to be typical of feline paraneoplastic alopecia (FPA). Malassezia-associated dermatitis can be associated with pruritus in cats with FPA.

    A double-blind, placebo-controlled clinical trial was conducted to determine the efficacy of clomipramine hydrochloride in cats with psychogenic alopecia. Twenty-five cats were randomly assigned to receive clomipramine hydrochloride (0.5 mg/kg orally q 24 hours) or placebo for 56 days. Eleven cats in each group completed the trial. The results of this study showed that clomipramine hydrochloride failed to demonstrate significant changes in the number of grooming bouts, hair regrowth, and the area of alopecia in cats with psychogenic alopecia when compared to a placebo. It was uncertain whether these results reflected a lack of drug efficacy, insufficient treatment duration, or an insufficient number of cases enrolled.

    Trichotillomania is a psychodermatologic disorder characterized by uncontrollable urge to pull one's own hair. Differential diagnoses include the most common forms of alopecia such as alopecia areata. It is usually associated with depression and obsessive-compulsive disorder. Trichotillomania treatment standardization is a gap in the medical literature. Recent studies demonstrated the efficacy of N-acetylcysteine (a glutamate modulator) for the treatment of the disease. We report the clinical case of a 12-year-old female patient who received the initial diagnosis of alopecia areata, but presented with clinical and dermoscopic features of trichotillomania. She was treated with the combination of psychotropic drugs and N-acetylcysteine with good clinical response. Due to the chronic and recurring nature of trichotillomania, more studies need to be conducted for the establishment of a formal treatment algorithm. PMID:28225970

    The syndrome of hereditary 1,25-dihydroxyvitamin D-resistant rickets (HVDRR) is a genetic disease of altered mineral homeostasis due to mutations in the vitamin D receptor (VDR) gene. It is frequently, but not always, accompanied by the presence of alopecia. Mouse models that recapitulate this syndrome have been prepared through genetic deletion of the Vdr gene and are characterized by the presence of rickets and alopecia. Subsequent studies have revealed that VDR expression in hair follicle keratinocytes protects against alopecia and that this activity is independent of the protein's ability to bind 1,25-dihydroxyvitamin D3 [1,25(OH)2D3]. In the present study, we introduced into VDR-null mice a human VDR (hVDR) bacterial artificial chromosome minigene containing a mutation that converts leucine to serine at amino acid 233 in the hVDR protein, which prevents 1,25(OH)2D3 binding. We then assessed whether this transgene recreated features of the HVDRR syndrome without alopecia. RT-PCR and Western blot analysis in one strain showed an appropriate level of mutant hVDR expression in all tissues examined including skin. The hVDR-L233S mutant failed to rescue the aberrant systemic and skeletal phenotype characteristic of the VDR null mouse due to the inability of the mutant receptor to activate transcription after treatment with 1,25(OH)2D3. Importantly, however, neither alopecia nor the dermal cysts characteristic of VDR-null mice were observed in the skin of these hVDR-L233S mutant mice. This study confirms that we have created a humanized mouse model of HVDRR without alopecia that will be useful in defining additional features of this syndrome and in identifying potential novel functions of the unoccupied VDR.

    Full Text Available Context: Alopecia areata (AA is a common form of localized, non-scarring hair loss. The etiopathogenesis of the disease is still unclear, but the role of autoimmunity is strongly suggested. AA is commonly associated with various autoimmune disorders; the most frequent among them is autoimmune thyroid disorders. Aim: To determine whether AA is associated with thyroid autoimmunity or thyroid function abnormalities in Egyptian patients. Materials and Methods: Fifty subjects with AA (37 males and 13 females without clinical evidence of thyroid disorders were selected from Dermatology Outpatient Clinic, Menoufiya University Hospital, Menoufiya Governorate, Egypt, during the period from June 2009 to February 2010. They were divided into 3 groups according to severity of AA. Fifty age and sex-matched healthy volunteers (35 males and 15 females were selected as a control group. Every case and control were subjected to history taking, complete general and dermatological examination. Venous blood samples were taken from cases and controls after taking their consents for measurement of thyroid stimulating hormone (TSH, free T3, freeT4 and detection of Anti-thyroglobulin Antibody (Tg-Ab and Anti-thyroid Peroxidase Antibody (TPO-Ab. Results: Subclinical hypothyroidism was detected in 16% of cases. There were statistically significant differences between cases and controls regarding levels of TSH, free T3 and free T4. There were significant differences between cases and controls regarding the presence of Tg-Ab and TPO-Ab. Conclusions: Every patient with AA should be screened for thyroid functions and presence of thyroid autoantibodies even in absence of clinical manifestations suggestive of thyroid affection.

    Full Text Available Objective: Alopecia areata (AA is a non-scarring disorder characterized by sudden loss of hairs. There is only one study that investigated the concepts of AA patients about their diseases. In this study self concepts about the causes and course of their disorder and their learning sources were asked to AA patients. Methods: 51 AA patients were enrolled to the study. The causes and the exacerbating factors of their disorders, how they have been directed to dermatology section, their concepts about the course of the disease and information sources were asked to the patients. Results: 30 of AA patients were male 21 were female. The ages of the patients varied between 15 and 63 years. While 49% of the patients accused stress as the cause, 18% was worried that it was a possible sign of cancer. 63% patients thought that stress played a role in exacerbating their disease. 60% of the patients thought that AA might improve completely but 16% did not have hope of improvement. While 39% patients received information from dermatologist, 28% did not investigate their disorder. The patients' answers to the questionaire were not different according to sex, education status, family history of the patients, recurrence of the disorder and if there was associated diseases but it was found significant that as the ages of the patients increased they more frequently thought that stress might be the possible exacerbating factor. Conclusion: AA patients blamed stress as the inducing and exacerbating factor of the disorder. However, as about 1/5 patients had worry of cancer and important rate of them had inadequate information about their disorder, dermatologists should give more information to the patients. Also listening and reducing the concern of the patients may positively effect the treatment.

    2004-02-01

    An alopecia and dermatopathy following pelvic fractures associated with vehicular trauma is reported in three cats. The animals presented 3-4 weeks post injury with acute hair loss, glistening appearance of the skin and erosions involving the lower back. Histological examination revealed atrophy of the hair follicles and adnexal structures and follicular telogenization, dermal fibroplasia and mild lymphocytic infiltrate, fibroplasia and inflammation in the panniculus. Vascular damage secondary to the external trauma to blood vessels supplying the skin over the lumbar region and subsequent ischaemia may represent the pathomechanism of this type of alopecia. Focal permanent hair loss can be expected.

    Central centrifugal cicatricial alopecia is an inflammatory type of central scalp hair loss seen primarily in women of African descent. The prevalence is unknown, but may vary from 2.7% to 5.7% and increases with age. This review outlines the history and current beliefs and identifies clues for future research for this enigmatic condition. Despite that the cause of central centrifugal cicatricial alopecia is unknown, research is ongoing. The role of cytokeratins, androgens, genetics, and various possible sources of chronic inflammation in disease pathogenesis remain to be elucidated.

    2011-05-01

    Menisci fulfill many functions within the complex biomechanics of the knee joint. In the case of meniscus lesions, sparing arthroscopic resection and surgical refixation are the treatments of choice. In terms of diagnosis, this means in general that histopathologic diagnostics are carried out on detached meniscus fragments of between 5 mm and 2 cm in size. A good knowledge of physiologically possible cellular and fibrous histological meniscus damage, as opposed to nonphysiological change regarded as normal with respect to age, is essential for diagnostic meniscus evaluation. The clinician expects clear statements from the pathologist regarding the severity of previous or secondary degenerative meniscus damage, the age and type of traumatic tears, and an appraisal of the relationship between trauma and meniscus damage from an insurance point of view. Close cooperation between the clinician and the pathologist allows for a fast and unambiguous correlation of anamnesis, the clinical picture, and morphological reporting such that problematic insurance cases can be clarified quickly.

    2014-01-01

    Full Text Available A 26-year-old Chinese male consulted with the team regarding his alopecia areata and vitiligo for which previous treatment was ineffective. The patient, a homosexual man, denied having a history of drug abuse and of blood transfusion. No member of his family had vitiligo or alopecia. Laboratory studies revealed that the serum for anti-human immunodeficiency virus (HIV antibody was positive. The patient′s CD4 lymphocyte count and CD4/CD8 ratio were both strikingly low (20 cells/mL and 0.04, but no other complaints or opportunistic infections were reported. One month after antiretroviral therapy, the patient′s alopecia areata dramatically improved, but no evident improvement in his vitiligo was found. This case is a very rare case of alopecia areata and vitiligo associated with HIV infection that might be attributed to the generation and maintenance of self-reactive CD8+ T-cells due to chronic immune activation with progressive immune exhaustion in HIV infection.

    Alopecia areata is a disease of the hair follicles, with strong evidence supporting autoimmune etiology. Alopecia areata is frequently associated with immune-mediated diseases with skin manifestations such as psoriasis and lichen planus, or without skin manifestations such as autoimmune thyroiditis and idiopathic thrombocytopenic purpura. Helicobacter pylori (H. pylori ) infection is present in around 50% of the world's population and has been associated with a variety of immune-mediated extra-digestive disorders including autoimmune thyroiditis, idiopathic thrombocytopenic purpura, and psoriasis. A case of a 43-year old man with an 8-mo history of alopecia areata of the scalp and beard is presented. The patient was being treated by a dermatologist and had psychiatric support, without any improvement. He had a history of dyspepsia and the urea breath test confirmed H. pylori infection. The patient went into remission from alopecia areata after H. pylori eradication. If such an association is confirmed by epidemiological studies designed for this purpose, new therapeutic options could be available for these patients, especially in areas where infection with H. pylori is highly prevalent.

    Development of optical biopsy methods has a great interest for medical diagnostics. In clinical and experimental studies it is very important to analyze blood circulation quickly and accurately, thereby laser Doppler flowmetry (LDF) is widely used. UV laser-induced fluorescence spectroscopy (UV LIFS) is express highly sensitive and widely-spread method with no destructive impact, high excitation selectivity and the possibility to use in highly scattering media. The goal of this work was to assess a correlation of UV laser-induced fluorescence spectroscopy and laser Doppler flowmetry parameters, and a possibility to identify or to differentiate various types of pathological changes in tissues according to their autofluorescence spectra. Three groups of patients with diffuse (symptomatic) alopecia, androgenic alopecia, and focal alopecia have been tested. Each groups consisted of not less than 20 persons. The measurements have been done in the parietal and occipital regions of the sculls. We used the original automated spectrofluorimeter to record autofluorescence spectra, and standard laser Doppler flowmeter BLF-21 (Transonic Systems, Inc., USA) to analyze the basal levels of blood circulation. Our results show that UV LIFS accurately distinguishes the zones with different types of alopecia. We found high correlation of the basal levels of blood circulation and the integrated intensity of autofluorescence in the affected tissue.

    Full Text Available Introduction: Alopecia areata is a unique, idiopathic disease in which there is patchy hair loss. The variable and uncertain natural history of alopecia areata is accounting for the multiplicity of uncritical claims for a large variety of therapeutic procedures. Aim: to find the therapeutic comparison between tacrolimus 0.1% ointment and minoxidil 2% solution. Material and Methods: Patients attending skin out patient department in Navodaya medical college hospital and research centre, Raichur were screened and the consenting consecutive cases of Aopecia Areata (AA from December 2010 to November 2011 were chosen for study. There were 75 patients in the study. It is a randomized, single blind, intension to treat study. The eligible patients for the study were randomly allocated into two groups-Group A and Group B (38 in Group A and 37 in Group B. Patients in Group A were treated with 2% Minoxidi solution to be applied twice daily over the alopecia patch, where as Patients in Group B were treated with Tacrolimus 0.1% ointment applied twice daily. Patients were followed up at 2, 4, 6, 8, 10 and 12 weeks. Alopecia Grading Score (AGS was calculated at baseline and 12 weeks. Regrowth Score (RGS was calculated at 12 weeks. Results: Total 69 patients completed the study (35 in Group A and 34 in Group B. In our study RGS ≥ 3 was observed in 65.71% of patients treated with Tinoxidil 2% solution and 44.12% of patients treated with Tacrolimus 0.1% ointment. Conclusion: In our study Minoxidil 2% solution had better stimulatory effect on hair growth compared to Tacrolimus 0.1% ointment in the treatment of mild to moderate patchy alopecia areata. The combination treatment may yield a better clinical response than either of the agents used singly.

    2004-07-01

    Full Text Available Background: Alopecia areata is a common, inflamatory and chronic disease of hair and nails, which in some cases result in growth inhibition and lose of hairs. Several factors such as genetic factors, autoimmunity, atopy, stress, fear etc, are known as effective factors in induction and severity of the disease, but the ethiology of this disease is not known exactly so far. Some evidences such as presence of an autoantibodies against hair follicules and infiltration of immunocompetent cells in affected areas of the disease lead that most investigators classify alopecia as autoimmune disease. In one investigation in immunology department of Tarbiat Modarres university concerning the humoral immunity in alopecia pathogenesis some evidences were found for the presences of a neoantigen in affected hair follicles. Since various studies indicates that cellular arm of the immune system is more important in alopecia areata pathogenesis, in this investigation we studied the existence of neoantigens in affected hair follicles using lymphocyte transformation test (LTT. Materials and Methods: The proliferation responses of peripheral blood mononuclear cells (MNC from alopecia patients and normal individuals were investigated against the follicular extracts of affected and normal hairs separately. Results: Our results indicate a non significant difference between proliferation responses of MNC’s from alopecia patients and normal controls against follicular extract of normal hairs. These responses were not significantly different against folliclar extracts of affected hairs as well. Regarding our results. Conclusion: We could not show the existence of a neoantigen in alopecia hair follicles, but the obtained results can not completely reject the role of a neoantigen in alopecia pathogenesis as well, because in LTT the responding cells are of memory type and these cells may be very low in peripheral blood. The immune response in this disease may be restricted

    2016-02-01

    Full Text Available Background Alopecia areata (AA is a common disease in the military population; however, a few studies have calculated the lifetime risk of alopecia areata in first-degree relatives of patients as well as the impact of stress. Objectives The primary aim of this study was to calculate the lifetime risk of alopecia areata in first-degree relatives of index patients. The secondary aim of this study was to assess the role of stressful events in the onset/recurrence of disease. Patients and Methods One hundred and twenty-one patients with alopecia areata and their first-degree relatives, which included 597 subjects in addition to 119 controls, were studied. We considered a gender and age-matched control for each patient. They were investigated for the occurrence of stressful events within the previous six months before the onset/recurrence of the disease. Results More than twenty-six percent of patients had a positive family history, while 6.4 percent of first-degree relatives were affected by alopecia areata. Lifetime risks were estimated at 7.6% for parents, 9.9% for siblings, and 6.4% for children. Eighty-eight patients (73.9% experienced stressful events within six months prior to the onset or recurrences of alopecia areata, while 32 subjects (26.9% of the control group reported such events in the last six months (P value = 0.000. Conclusions Calculated lifetime risks can be used in genetic counseling. It appears that stressful events can be considered to be contributing factors in the development of alopecia areata. Also, according to our results, the role of stress in the recurrence of alopecia areata is more prominent than the primary development of the disease.

P<0.05 was considered as significant. Results: Mean age and body mass index were 58.96±12.8 year and 25.6±4.15 kg/m2 respectively in whole population. Findings not show any significant association between type II diabetes and androgenic alopecia (P<0.05. Comparison of distribution of alopecia severity according to Ludwish criteria separately showed similar result. In addition to, there was not any significant relationship between diabetes and alopecia after adjusting with body mass index as confounding factor (P<0.05. Conclusion: In the present study, there was not any significant relationship between type II diabetes and androgenic alopecia among diabetes and healthy women. However, more researches need to investigate this relationship in both gender and assess insulin resistant indices as homeostasis model assessment-estimated insulin resistance and androgenic alopecia.

    Kristyn Deen

    2015-07-01

    Full Text Available Syringomas are benign adnexal neoplasms of eccrine lineage, which occur most commonly in the periorbital region in middle-aged females. These cutaneous lesions rarely occur on the scalp, are typically asymptomatic and are predominantly of cosmetic significance. Involvement of the scalp may be indistinguishable from that of scarring alopecia. We present an unusual case of clinically inapparent syringomas occurring on the scalp of a 56-year-old female with alopecia who was subsequently diagnosed with lichen planopilaris after repeated scalp biopsy. In patients with unexplained hair loss, or in cases that are refractive to treatment, clinicians should perform scalp biopsy to exclude the diagnosis of rare neoplastic lesions like syringomas and to diagnose associated conditions.

  15. Protection against chemotherapy-induced alopecia: targeting ATP-binding cassette transporters in the hair follicle?

    Science.gov (United States)

    Haslam, Iain S; Pitre, Aaron; Schuetz, John D; Paus, Ralf

    2013-11-01

    Currently, efficacious treatments for chemotherapy-induced alopecia (hair loss) are lacking, and incidences of permanent hair loss following high-dose chemotherapy are on the increase. In this article, we describe mechanisms by which the pharmacological defense status of the hair follicle might be enhanced, thereby reducing the accumulation of cytotoxic cancer drugs and preventing or reducing hair loss and damage. We believe this could be achieved via the selective increase in ATP-binding cassette (ABC) transporter expression within the hair follicle epithelium, following application of topical agonists for regulatory nuclear receptors. Clinical application would require the development of hair follicle-targeted formulations, potentially utilizing nanoparticle technology. This novel approach has the potential to yield entirely new therapeutic options for the treatment and management of chemotherapy-induced alopecia, providing significant psychological and physical benefit to cancer patients.

  17. CRF receptor antagonist astressin-B reverses and prevents alopecia in CRF over-expressing mice.

    Directory of Open Access Journals (Sweden)

    Lixin Wang

    Full Text Available Corticotropin-releasing factor (CRF signaling pathways are involved in the stress response, and there is growing evidence supporting hair growth inhibition of murine hair follicle in vivo upon stress exposure. We investigated whether the blockade of CRF receptors influences the development of hair loss in CRF over-expressing (OE-mice that display phenotypes of Cushing's syndrome and chronic stress, including alopecia. The non-selective CRF receptors antagonist, astressin-B (5 µg/mouse injected peripherally once a day for 5 days in 4-9 months old CRF-OE alopecic mice induced pigmentation and hair re-growth that was largely retained for over 4 months. In young CRF-OE mice, astressin-B prevented the development of alopecia that occurred in saline-treated mice. Histological examination indicated that alopecic CRF-OE mice had hair follicle atrophy and that astressin-B revived the hair follicle from the telogen to anagen phase. However, astressin-B did not show any effect on the elevated plasma corticosterone levels and the increased weights of adrenal glands and visceral fat in CRF-OE mice. The selective CRF₂ receptor antagonist, astressin₂-B had moderate effect on pigmentation, but not on hair re-growth. The commercial drug for alopecia, minoxidil only showed partial effect on hair re-growth. These data support the existence of a key molecular switching mechanism triggered by blocking peripheral CRF receptors with an antagonist to reset hair growth in a mouse model of alopecia associated with chronic stress.

    Full Text Available Background and Design: Current studies link a possible relationship between vitamin D deficiency and many autoimmune diseases. Alopecia areata(AA is a frequent autoimmune dermatological disease. The aim of this study was to investigate the relationship between vitamin D levels and alopecia areata; a frequent autoimmune dermatological disease. Materials and Methods: The 25 hydroxyvitamin D (25 OH D levels of 40 patients with alopecia areata and age, gender and skin phototype matched healthy controls were evaluated. Serum 25 OH D was measured in all subjects, grouped as normal/sufficient (> 30 ng/ml, insufficient (15-30 ng/ml and deficient (0,05. In both groups 97,5% of patients had 25 OH D levels under normal range. Conclusion: Vitamin D levels of patients with AA was similar with the control group This similarity may suggest that a connection between vitamin D and AA does not exist. However, it may also indicate that the relationship between AA and Vitamin D is not via the level but receptor (number and / or structure of vitamin D.

    Full Text Available Objectives: Follicular unit transplant is a widely used surgical treatment for androgenic alopecia. However, for patients with extensive hair loss (Norwood 5 and above, scalp donor hair are not sufficient to cover all areas of baldness. This study aims to assess suitability of beard and body donor hair when transplanted to the scalp. Materials and Methods: In 35 male patients having varying degrees of androgenic alopecia, body and beard donor hair were extracted by follicular unit extraction method (under local anesthesia. They were transplanted in different locations of the scalp. Follow-up was carried out at various intervals (6 months to 2 years. The hairs were observed for colour, curl and calibre. Results: In all the patients, there was no change in the colour, curl or calibre of the transplanted body/beard hair. They maintained the same characteristics as in their original location. Conclusion: Body and beard hair can be used as additional donor resource for treating androgenic alopecia. These hairs, however, do not change their colour, curl, and shaft diameter (calibre. Thus, proper planning is a must when using the different types of donor hair for transplanting.

    Alopecia areata (AA) is a nonscarring and recurrent disease characterized by hair loss that may significantly affect patient health-related quality of life (HRQoL). Given the lack of reliable and accurate reporting of HRQoL status in patients with AA, we analyzed data from 532 AA patients from the National Alopecia Areata Registry whose registry record included HRQoL assessments using three validated instruments: Skindex-16, brief version of the Fear of Negative Evaluation Scale, and Dermatology Life Quality Index. The mean HRQoL scores were compared with previously reported HRQoL levels from healthy controls and patients with other skin diseases. Two-step cluster analysis of Skindex-16 scales divided patients into two groups: 481 (57%) with good HRQoL and 361 (43%) with poor HRQoL. Multivariate logistic regression modeling revealed a set of risk factors for poor HRQoL: age HRQoL status of AA patients and may guide patient care in the future.

    Histopathology is an art of analyzing and interpreting the shapes, sizes and architectural patterns of cells and tissues within a given specific clinical background and a science by which the image is placed in the context of knowledge of pathobiology, to arrive at an accurate diagnosis. To function effectively and safely, all the procedures and activities of histopathology laboratory should be evaluated and monitored accurately. In histopathology laboratory, the concept of quality control is applicable to pre-analytical, analytical and post-analytical activities. Ensuring safety of working personnel as well as environment is also highly important. Safety issues that may come up in a histopathology lab are primarily those related to potentially hazardous chemicals, biohazardous materials, accidents linked to the equipment and instrumentation employed and general risks from electrical and fire hazards. This article discusses quality management system which can ensure quality performance in histopathology laboratory. The hazards in pathology laboratories and practical safety measures aimed at controlling the dangers are also discussed with the objective of promoting safety consciousness and the practice of laboratory safety.

    Alopecia areata represents an autoimmune pathological process driven primarily by cellular aberrations contained within the immune system, which activates various humoral and cellular elements of the immune response. The aim of this study was to determine the mRNA expression levels of T-bet and GATA-3 as potential inducers of T helper (Th)1 and Th2 differentiation, respectively, as well as Th1(IFN-γ) and Th2(IL-4) cytokine mRNA expression in patients with alopecia areata. Using real-time reverse transcriptase PCR (RT-PCR), the relative amounts of T-bet, GATA-3, IFN-γ, and IL-4 mRNA transcripts were determined in PBMCs from 20 Iranian patients with alopecia areata and compared with those of 20 healthy control subjects. In comparison with the normal group, T-bet and IFN-γ mRNA expression levels were significantly up-regulated in the alopecia areata patients, while GATA-3 and IL-4 mRNA expression levels were down-regulated. Notably, positive correlation (P < 0.05) was found between IFN-γ and T-bet levels in patients and controls. In addition, significant positive correlations existed between GATA-3 and IL-4 (P < 0.05). These results indicate that a Th1/Th2 imbalance exists in alopecia areata, and it may be implicated in the pathogenesis of disease.

    Full Text Available Background: Tonsillar diseases are common in paediatric and adult otolaryngological practice. These diseases require tonsillectomy. Specimens are subjected to histopathology routinely in my institution for fear of infections and tumour without consideration for risk factors. The financial burden is on the patients and waste of histopathologist′s man hour because other specimens are left un-attended. This study aims to find out the necessity of routine histopathology of tonsil specimens. Materials and Methods : A 2 year retrospective review of the histopathological results of two (paediatric and adult groups of 61 patients managed for tonsillar diseases at the ENT UNIT of Jos University Teaching Hospital from July 2005 to June, 2007. Data extracted included biodata, clinical features and histopathological diagnosis. Result : The 61 patients comprise 35 children and 26 adults. The youngest and oldest paediatric patients were 1 year and 3 months and 16 years respectively, a range of 1 year 3 months to 16 years. The youngest and oldest adults were 17 and 50 years with a range of 17-50 years. Groups mean ages were 5.1 and 28.5 years. The gender ratios were 1:2.7 and 1:1.9 respectively. One adult was HIV positive. The histopathological diagnosis were chronic nonspecific tonsillitis in 10(16.6%, follicular tonsillitis in 23(38.3%, chronic suppurative tonsillitis in 10(16.6%, lymphoid hyperplasia in 18(30.0% and lymphoma in 1(1.0% respectively. Conclusion : Histopathologic request for tonsillectomy specimens should be based on certain risk factors with consideration of the cost to patients and to spare the histopathologist′s man hour.

    Our 10-year experience with PUVA treatment for alopecia areata, partialis, totalis and universalis was retrospectively reviewed using charts and follow-up questionnaires for 70 patients at St John`s Institute of Dermatology. In all cases, several previous therapies were judged to be unsatisfactory prior to starting PUVA, and many cases were already deemed clinically refractory prior to referral for PUVA. If cases of vellus hair growth are excluded, and those who lost their PUVA-induced regrowth rapidly on follow-up, the effective success rate was at best 6.3% for alopecia areata partialis, 12.5% for alopecia areata totalis and 13.3% for alopecia areata universalis. We affirm that PUVA is generally not an effective treatment for alopecia areata. (Author).

    Full Text Available The technological progress in the digitalization of a complete histological glass slide has opened a new door in the tissue based diagnosis. Automated slide diagnosis can be made possible by the use of mathematical algorithms which are formulated by binary codes or values. These algorithms (diagnostic algorithms include both object based (object features, structures and pixel based (texture measures. The intra- and inter-observer errors inherent in the visual diagnosis of a histopathological slide are largely replaced by the use of diagnostic algorithms leading to a standardized and reproducible diagnosis. The present paper reviews the advances in digital histopathology especially related to the use of mathematical algorithms (diagnostic algorithms in the field of oral histopathology. The literature was reviewed for data relating to the use of algorithms utilized in the construction of computational software with special applications in oral histopathological diagnosis. The data were analyzed, and the types and end targets of the algorithms were tabulated. The advantages, specificities and reproducibility of the software, its shortcomings and its comparison with traditional methods of histopathological diagnosis were evaluated. Algorithms help in automated slide diagnosis by creating software with possible reduced errors and bias with a high degree of specificity, sensitivity, and reproducibility. Akin to the identification of thumbprints and faces, software for histopathological diagnosis will in the near future be an important part of the histopathological diagnosis.

    Full Text Available Rehab Nabil Shamma, Mona Hassan AburahmaDepartment of Pharmaceutics and Industrial Pharmacy, Faculty of Pharmacy, Cairo University, Cairo, EgyptAbstract: Spironolactone (SL is a US Food and Drug Administration-approved drug for the treatment of hypertension and various edematous conditions. SL has gained a lot of attention for treating androgenic alopecia due to its potent antiandrogenic properties. Recently, there has been growing interest for follicular targeting of drug molecules for treatment of hair and scalp disorders using nanocolloidal lipid-based delivery systems to minimize unnecessary systemic side effects associated with oral drug administration. Accordingly, the objective of this study is to improve SL efficiency and safety in treating alopecia through the preparation of colloidal nanostructured lipid carriers (NLCs for follicular drug delivery. SL-loaded NLCs were prepared by an emulsion solvent diffusion and evaporation method using 23 full factorial design. All of the prepared formulations were spherical in shape with nanometric size range (215.6–834.3 nm and entrapment efficiency >74%. Differential scanning calorimetry thermograms and X-ray diffractograms revealed that SL exists in amorphous form within the NLC matrices. The drug release behavior from the NLCs displayed an initial burst release phase followed by sustained release of SL. Confocal laser scanning microscopy confirmed the potential of delivering the fluorolabeled NLCs within the follicles, suggesting the possibility of using SL-loaded NLCs for localized delivery of SL into the scalp hair follicles.Keywords: spironolactone, androgenic alopecia, nanostructured lipid carriers, follicular targeting, confocal laser scanning microscopy

  12. Alopecia in a viable phospholipase C delta 1 and phospholipase C delta 3 double mutant.

    Directory of Open Access Journals (Sweden)

    Fabian Runkel

    Full Text Available BACKGROUND: Inositol 1,4,5trisphosphate (IP(3 and diacylglycerol (DAG are important intracellular signalling molecules in various tissues. They are generated by the phospholipase C family of enzymes, of which phospholipase C delta (PLCD forms one class. Studies with functional inactivation of Plcd isozyme encoding genes in mice have revealed that loss of both Plcd1 and Plcd3 causes early embryonic death. Inactivation of Plcd1 alone causes loss of hair (alopecia, whereas inactivation of Plcd3 alone has no apparent phenotypic effect. To investigate a possible synergy of Plcd1 and Plcd3 in postnatal mice, novel mutations of these genes compatible with life after birth need to be found. METHODOLOGY/PRINCIPAL FINDINGS: We characterise a novel mouse mutant with a spontaneously arisen mutation in Plcd3 (Plcd3(mNab that resulted from the insertion of an intracisternal A particle (IAP into intron 2 of the Plcd3 gene. This mutation leads to the predominant expression of a truncated PLCD3 protein lacking the N-terminal PH domain. C3H mice that carry one or two mutant Plcd3(mNab alleles are phenotypically normal. However, the presence of one Plcd3(mNab allele exacerbates the alopecia caused by the loss of functional Plcd1 in Del(9olt1Pas mutant mice with respect to the number of hair follicles affected and the body region involved. Mice double homozygous for both the Del(9olt1Pas and the Plcd3(mNab mutations survive for several weeks and exhibit total alopecia associated with fragile hair shafts showing altered expression of some structural genes and shortened phases of proliferation in hair follicle matrix cells. CONCLUSIONS/SIGNIFICANCE: The Plcd3(mNab mutation is a novel hypomorphic mutation of Plcd3. Our investigations suggest that Plcd1 and Plcd3 have synergistic effects on the murine hair follicle in specific regions of the body surface.

    Current observations link vitamin D deficiency to many autoimmune diseases. There are limited data on vitamin D in Alopecia Areata, an autoimmune disease which in our experience shows seasonality in most of its remitting-relapsing forms. Our results demonstrate the presence of insufficiency of 25-hydroxyvitamin D (25OH-D) in many patients with various clinical forms, correlated with the expected increase of the values of Parathyroid Hormone (PTH). This could suggest the possible clinical use of vitamin D in the management of this frustrating disease.

    A girl is reported with a hitherto apparently undescribed ectodermal dysplasia syndrome. The main findings include: alopecia, onychodysplasia, hypohidrosis, sensorineural deafness, skin with a tan color and hyperkeratosis (involving also plams and soles), unusual facies (with slight auricle and nose abnormalities), pectus excavatum, severe hyperopia, EEG abnormalities, and retarded bone age. The patient also presents mongoloid palpebral slanting, narrow palpebral fissures, bilateral esotropia, photophobia and dermatoglyphics with extensive ridge dissociation. The etiology is unknown but presumed to be genetic, possibly due to the homozygous state of an autosomal recessive mutation.

  18. Obliteration of alopecia by hair-lifting: a new concept and technique.

    Blanchard, G; Blanchard, B

    1977-09-01

    A new concept and technique of treatment of male-pattern alopecia are described. The concept is to remove, in serial stages, segments of skin that measure about 3 cm by 7 to 10 cm from the bald area of an alopecic scalp, and to raise the remaining hairy portion into the previously bald area.The technique consists of undermining the skin in the normal plane of cleavage between the galea and the sub-aponeurotic loose connective tissue after each removal of bald skin and "lifting" of hairy skin into the operative defects as they are obliterated by primary closure. By this method, which we call hair-lifting, the patient benefits also from an associated partial face-lift. Whatever remains of baldness after as much hair-lifting as feasible has been performed, is filled with "punch" grafts or free or pedicled strips. Each stage of the procedure is done under local anesthesia. The entire procedure is particularly suitable for tonsure baldness in men and even in the skull-cap type of androgenic alopecia in women.

    Although minoxidil (MX) is a drug known to stimulate hair growth, the treatment of androgenic alopecia could be improved by delivery strategies that would favor drug accumulation into the hair follicles. This work investigated in vitro the potential of iontophoresis to achieve this objective using MX sulfate (MXS), a more water-soluble derivative of MX. Passive delivery of MXS was first determined from an ethanol-water solution and from a thermosensitive gel. The latter formulation resulted in greater accumulation of MXS in the stratum corneum (skin's outermost layer) and hair follicles and an overall decrease in absorption through the skin. Anodal iontophoresis of MXS from the same gel formulation was then investigated at pH 3.5 and pH 5.5. Compared with passive delivery, iontophoresis increased the amount of drug reaching the follicular infundibula from 120 to 600 ng per follicle. In addition, drug recovery from follicular casts was threefold higher following iontophoresis at pH 5.5 compared with that at pH 3.5. Preliminary in vivo experiments in rats confirmed that iontophoretic delivery of MXS facilitated drug accumulation in hair follicles. Overall, therefore, iontophoresis successfully and significantly enhanced follicular delivery of MX suggesting a useful opportunity for the improved treatment of alopecia.

    Full Text Available Background: Alopecia areata (AA and psoriasis are associated with various psychiatric comorbidities. Both greatly affect the quality of life (QOL of patients and psychiatric comorbidities can further worsen it. Thus there is need to recognise psychiatric comorbidities and treat them in these patients. Aims: To determine the psychiatric morbidity and the QOL in these patients to study the factors affecting them. Methodology: 50 patients each of psoriasis and AA were included. 50 people accompanying these patients served as control group. They were diagnosed for psychiatric disorders by clinical interview. Scales used were severity of alopecia tool for AA, psoriasis area and severity index for psoriasis, WHO-QOL scale, Hamilton Rating Scale for anxiety and depression. Results: 22% and 38% patients in AA and psoriasis group respectively suffered from psychiatric disorder, depression was present in 18% and 24% of patients and 4% and 12% had anxiety disorders in respective groups. The control group had only 6% of psychiatric comorbidities. QOL scores had negative correlation with Hamilton-A, Hamilton-D and severity of psoriasis scores and they were statistically significant but not with severity of AA. Conclusion: Thus AA and psoriasis patients had more prevalence of psychiatric comorbidities and it had bearing on their QOL.

    Traction alopecia is hair loss that occurs after persistent pulling (e.g., during cosmetic procedures) on the roots of hair over time. Unlike plucking, which is painful, persistent pulling may go unnoticed until a patient presents with either bald spots or diffuse telogen shedding. Each hair follicle in the scalp contains an arrector pili muscle that, when contracted, erects the hair. The smooth muscle in the arrector pili expresses α1 adrenergic receptors (α1 -AR). As such, we hypothesized that contraction of the arrector pili muscle via an α1 -AR agonist would increase the threshold of force required to pluck hair during cosmetic procedures. Female subjects, ages 18-40, were recruited to study the effect of topically applied phenylephrine, a selective α1 -AR agonist, on epilation force and hair shedding during cosmetic procedures. In our blinded study, 80% of subjects demonstrated reduced shedding on days using phenylephrine compared to days using a placebo solution. The average reduction in hair loss was approximately 42%. In addition, the force threshold required for epilation increased by approximately 172% following topical phenylephrine application. To our knowledge this is the first study demonstrating the utility of α1 -AR agonists in the treatment of traction alopecia and hair shedding during cosmetic procedures.

    Full Text Available Aim. Many studies demonstrated that alopecia areata (AA and vitiligo are commonly associated with autoimmune thyroid diseases. We aimed to investigate the frequency of thyroid dysfunctions and autoimmunity related with vitiligo and AA. Material and Methods. 200 patients, 92 AA and 108 vitiligo diagnosed, were surveyed retrospectively. The control population was in reference range and from Konya, central Anatolian region of Turkey. Thyroid function tests (free T3, free T4, and TSH and serum thyroid autoantibody (anti-TG, anti-TPO levels were evaluated in all patients. Results. In vitiligo patients, 9 (8.3% had elevated anti-TG levels and 16 (14.8% had elevated anti-TPO, and in 17 patients (15.7% TSH levels were elevated and 3 (2.8% patients had elevated fT4 levels and 5 (4.6% had elevated fT3 levels. Within AA patients, 2 (2.2% had anti-TG elevation and 13 (14.1% had anti-TPO elevation, in 7 patients (7.6% TSH were elevated, and in 1 patient (1.1% fT4 were elevated and 5 (5.4% patients had elevated fT3 levels. Conclusion. In our study, impaired thyroid functions and thyroid autoantibodies in vitiligo and AA patients were identified at lower rates than the previous studies. According to results of this study there is no need for detailed examination in alopecia areata and vitiligo patients without clinical history.

    Balding causes widespread psychological distress but is poorly controlled. The commonest treatment, minoxidil, was originally an antihypertensive drug that promoted unwanted hair. We hypothesized that another serendipitous discovery, increased eyelash growth side-effects of prostamide F(2α)-related eyedrops for glaucoma, may be relevant for scalp alopecias. Eyelash hairs and follicles are highly specialized and remain unaffected by androgens that inhibit scalp follicles and stimulate many others. Therefore, we investigated whether non-eyelash follicles could respond to bimatoprost, a prostamide F(2α) analog recently licensed for eyelash hypotrichosis. Bimatoprost, at pharmacologically selective concentrations, increased hair synthesis in scalp follicle organ culture and advanced mouse pelage hair regrowth in vivo compared to vehicle alone. A prostamide receptor antagonist blocked isolated follicle growth, confirming a direct, receptor-mediated mechanism within follicles; RT-PCR analysis identified 3 relevant receptor genes in scalp follicles in vivo. Receptors were located in the key follicle regulator, the dermal papilla, by analyzing individual follicular structures and immunohistochemistry. Thus, bimatoprost stimulates human scalp follicles in culture and rodent pelage follicles in vivo, mirroring eyelash behavior, and scalp follicles contain bimatoprost-sensitive prostamide receptors in vivo. This highlights a new follicular signaling system and confirms that bimatoprost offers a novel, low-risk therapeutic approach for scalp alopecias.

    Spironolactone (SL) is a US Food and Drug Administration-approved drug for the treatment of hypertension and various edematous conditions. SL has gained a lot of attention for treating androgenic alopecia due to its potent antiandrogenic properties. Recently, there has been growing interest for follicular targeting of drug molecules for treatment of hair and scalp disorders using nanocolloidal lipid-based delivery systems to minimize unnecessary systemic side effects associated with oral drug administration. Accordingly, the objective of this study is to improve SL efficiency and safety in treating alopecia through the preparation of colloidal nanostructured lipid carriers (NLCs) for follicular drug delivery. SL-loaded NLCs were prepared by an emulsion solvent diffusion and evaporation method using 23 full factorial design. All of the prepared formulations were spherical in shape with nanometric size range (215.6-834.3 nm) and entrapment efficiency >74%. Differential scanning calorimetry thermograms and X-ray diffractograms revealed that SL exists in amorphous form within the NLC matrices. The drug release behavior from the NLCs displayed an initial burst release phase followed by sustained release of SL. Confocal laser scanning microscopy confirmed the potential of delivering the fluorolabeled NLCs within the follicles, suggesting the possibility of using SL-loaded NLCs for localized delivery of SL into the scalp hair follicles.

    Palmoplantar keratoderma-congenital alopecia (PPKCA) syndrome is a rare genodermatosis, with two clinically recognizable forms: dominant (Type 1) and recessive (Type 2). Reports of only 18 patients have been published to date, and the molecular basis of the condition is unknown. We describe two cases with PPKCA Type 2 (PPKCA2), comprising a novel patient, originally reported as an example of autosomal ichthyosis follicularis-atrichia-photophobia syndrome, and the 6-year follow-up of a previously published case. Extensive molecular studies of both patients excluded mutations in all the known genes associated with PPK and partially overlapping syndromes. The striking similarities between these two patients confirm PPKCA2 as a discrete genodermatosis, of which the main features are congenital and universal alopecia, diffuse keratosis pilaris, facial erythema, and a specific PPK with predominant involvement of the fingertips and borders of the hands and feet, with evolution of sclerodactyly, contractures and constrictions. Clinical follow-up of these patients has demonstrated progressive worsening of the hand involvement and attenuation of facial erythema.

    Full Text Available Chemical peeling with 88% phenol was carried out on 142 sites of stable vitiligo (hairy-126, non hairy-16 and on 69 sites of alopecia areata (AA. After cleansing and defatting, phenol was applied on affected areas till a uniform frost appeared. On healing, all the lesions of vitiligo showed perifollicular pigmentation in hairy areas and perilesional repigmentation in non hairy areas. These were further treated with PUVA/PUVASOL. After the healing, 82.5% of hairy sites and 81.3% of non hairy sites showed repigmentation. In cases of AA, patients developed vellus hair. In AA, 72.5% had good regrowth and 27.5% had poor response. Side effects seen were hypopigmentation (58 AA, hyperpigmentation (11 AA, persistent erythema (42 vitiligo, 28 AA, demarcation lines (4 AA, secondary bacterial infection (2 vitiligo, 5 AA and superficial scarring (2 vitiligo, 7 AA. The wounding action of phenol is useful to repigment the vitiligo patches and for induction of regrwoth of hair in alopecia areata.

    Full Text Available Background: Mechanism leading to an abrupt hair loss in diffuse alopecia areata (AA remains unclear. Aims: To explore the characteristics of diffuse AA and possible factors involved in its pathogenesis. Methods: Clinical and laboratory data of 17 diffuse AA patients and 37 patchy AA patients were analyzed retrospectively. Serum IgE level was evaluated in all diffuse and patchy AA patients, as well as 27 healthy subjects without hair loss to serve as normal control. Univariate analysis was performed using Fisher′s exact test and Wilcoxon rank-sum test. Associations between inflammatory cell infiltration and laboratory values were analyzed using Spearman rank correlation test. Results: The mean age of patients with diffuse AA was 27 years with a mean disease duration of 1.77 months. All of them presented in spring or summer with an acute onset of diffuse hair loss preceded by higher incidence of scalp pruritus. Although no statistically significant difference on the incidence of atopic disease among three groups has been found, serum IgE level in diffuse AA was higher than that in healthy controls, but was comparable to that in patchy AA group. Histopathology of lesional scalp biopsies showed more intense infiltration comprising of mononuclear cells, eosinophils, CD3 + , and CD8 + T cells around hair bulbs in diffuse AA group than in patchy AA group. Moreover, IgE level in diffuse AA patients positively correlated with intensity of infiltration by mononuclear cells, eosinophils, and CD8 + T cells. Conclusions: Hypersensitivity may be involved in pathogenesis of diffuse AA. The acute onset of diffuse AA may be related to intense local inflammatory infiltration of hair loss region and an increase in serum IgE level.

    The authors studied the histopathologic evolution of arthritis in nonirradiated and irradiated hamsters infected with Borrelia burgdorferi. Nonirradiated hamsters injected in the hind paws with B. burgdorferi developed an acute inflammatory reaction involving the synovium, periarticular soft tissues, and dermis. This acute inflammatory reaction was short-lived and was replaced by a mild chronic synovitis as the number of detectable spirochetes in the synovium, periarticular soft tissues, and perineurovascular areas diminished. Exposing hamsters to radiation before inoculation with B. burgdorferi exacerbated and prolonged the acute inflammatory phase. Spirochetes also persisted longer in the periarticular soft tissues. A major histopathologic finding was destructive and erosive bone changes of the hind paws, which resulted in deformation of the joints. These studies should be helpful in defining the immune mechanism participating in the onset, progression, and resolution of Lyme arthritis.

    Full Text Available Diseases of the oral cavity may be either a reflection of system or cutaneous diseases or can be seen as a primary oral lesion. These lesions are inflammatory reactions due to miscellaneous mechanisms, ulceration or erosion, reactive proliferative nodules, precancerous or neoplastic diseases. In this study, microscopic features of the most common diseases, together with their differential diagnosis are discussed. Some of the diseases of the oral cavity have overlapping histopathological findings. In these conditions, ancillary methods such as immunoflourescence or immunohistochemistry can be performed. Deep biopsies from representative areas are essential for proper histopathological diagnosis. Moreover, informing the pathologist about the exact anatomic localization of the biopsy, as well as the clinical findings of the lesion is crucial for a better approach.

    Purpose: To evaluate the histopathologic changes in the conjunctiva of patients with conjunctivochalasis (CCh) compared to age-matched controls. Methods: This cross-sectional, controlled study included 27 eyes of 27 patients with CCh and 16 eyes of 16 age-matched controls. A biopsy of the bulbar conjunctiva was performed along the temporal lower lid margin before cataract surgery in both groups. Histopathologic evaluation of the specimens was done with light microscopy using staining with hematoxylin/eosin, periodic acid Schiff, and van Gieson elastic stain. Various histopathologic features of the conjunctival epithelium and stroma were compared between the two groups. Results: The mean age of patients was 62.4 ± 6.9 years in the CCh group and 65.1 ± 6.3 years in the control group (P = 0.54). No significant differences were noted between the two groups in terms of conjunctival epithelial changes including papillomatosis, epithelial clefts, epithelial goblet cells, or infiltration of inflammatory cells. Mean thickness of the conjunctival stroma was 0.21 ± 0.08 mm in the CCh group and 0.26 ± 0.21 mm in the control group (P = 0.10). For the conjunctival stroma, there were no significant differences between the two groups in terms of elastosis, fibrosis, lymphangiectasia, or infiltration of inflammatory cells. Conclusion: No noticeable differences were found in the histopathologic features by light microscopy between eyes with CCh and those of age-matched controls. Therefore, the primary pathology of CCh may not be within the conjunctiva itself. Instead, loose attachment of the conjunctiva to the underlying tissue may be the reason for the redundant folds in the bulbar conjunctiva. PMID:27994801

    Full Text Available Pseudoepitheliomatous hyperplasia is an extremely rare condition presenting as a lesion on the glans penis in older men. Physical exam without biopsy cannot differentiate malignant from nonmalignant growth. We report a case of large penile mass in an elderly male with a history of lichen sclerosis, highly suspicious for malignancy. Subsequent surgical removal and biopsy demonstrated pseudoepitheliomatous hyperplasia, an unusual benign histopathologic diagnosis with unclear prognosis. We review the literature and discuss options for treatment and surveillance.

    Linear immunoglobulin A (IgA) bullous dermatosis (LABD) is an autoimmune mucocutaneous disease characterized by subepidermal blistering induced by IgA autoantibodies against several autoantigens in the basal membranous zone of the skin and mucosal tissue. Although diaminodiphenyl sulfone (DDS), also known as dapsone, is generally recognized as the first-line therapy for LABD, DDS can induce several severe side effects. We present a Japanese case of LABD with DDS-induced hemolytic anemia and alopecia. In the present case, the DDS-induced hemolytic anemia and hair loss made the DDS monotherapy difficult. When DDS is used in LABD patients with iron deficiency anemia (IDA), hemolytic anemia is concealed by IDA. It is thus necessary to carefully and frequently examine the laboratory data to find the signs of DDS-induced hemolytic anemia. Even though there is no literature on DDS-induced alopecia, alopecia was reported as one of the side effects of DDS in an FDA report, and, in our case, hair loss was improved after reducing its dosage. We have to recognize that alopecia is one of the side effects of DDS and that careful management is needed in order not to overlook the adverse side effects of DDS when treating LABD patients.

    Alopecia (hair loss) has been observed in several marine mammal species and has potential energetic consequences for sustaining a normal core body temperature, especially for Arctic marine mammals routinely exposed to harsh environmental conditions. Polar bears (Ursus maritimus) rely on a thick layer of adipose tissue and a dense pelage to ameliorate convective heat loss while moving between sea ice and open water. From 1998 to 2012, we observed an alopecia syndrome in polar bears from the southern Beaufort Sea of Alaska that presented as bilaterally asymmetrical loss of guard hairs and thinning of the undercoat around the head, neck, and shoulders, which, in severe cases, was accompanied by exudation and crusted skin lesions. Alopecia was observed in 49 (3.45%) of the bears sampled during 1,421 captures, and the apparent prevalence varied by years with peaks occurring in 1999 (16%) and 2012 (28%). The probability that a bear had alopecia was greatest for subadults and for bears captured in the Prudhoe Bay region, and alopecic individuals had a lower body condition score than unaffected individuals. The cause of the syndrome remains unknown and future work should focus on identifying the causative agent and potential effects on population vital rates.

    Full Text Available Background: Intrathyroid lymphoid tissue is accrued in Hashimoto thyroiditis (HT. Histologically, this acquired lymphoid tissue bears a close resemblance to mucosa-associated lymphoid tissue (MALT and can evolve to lymphoma. Aim: To demonstrate the morphological, and immunohistochemical profiles of Hashimoto thyroiditis and to ascertain the importance of light chain restriction in distinguishing HT with extensive lymphoplasmacytoid infiltrate from MALT lymphoma. Materials and Methods: We studied histopathologically and immunohistochemically (CD20, CD3, Igk, Igl and cytokeratin 30 cases of HT for evaluation of the lymphoid infiltrate and the presence of lymphoepithelial lesions (LELs. Distinguishing between early thyroid lymphoma and HT was evaluated by light chain restriction. These findings were compared with two cases of primary thyroid lymphoma. Results: The histopathological findings were characteristic of HT. Immunohistochemistry confirmed inconspicuous, rare B-cell LELs as well as a prominent T-lymphocyte population. Testing for light chain restriction showed polyclonal population of plasma cells. The cases of MALT lymphoma had distinct destructive lymphoepithelial lesions, B-cell immunophenotyping and showed kappa light chain restriction in the plasmacytoid population. Conclusions: Hashimoto thyroiditis differs both histopathologically and immunohistochemically from thyroid lymphoma. In suspicious cases, immunohistochemistry could be helpful in reaching a definitive diagnosis.

    Full Text Available Background and Design: Autologous serum skin test (ASST, the best in-vivo test displaying in vitro basophil histamin releasing activity, is used in the diagnosis of chronic autoimmune urticaria. Besides, it is cheap and is easy to perform. It has been found that in ASST-positive chronic urticaria patients, autoimmune thyroid disease especially and other autoimmune diseases were more common and the level of autoimmune markers were higher compared to others. Autoimmunity is accused in the pathogenesis of alopecia areata and vitiligo. In this study, we assessed ASST results in healthy controls and those with autoimmune diseases, and aimed to explore the effects of thyroid autoantibodies and other factors in ASST positivity. Materials and Methods: ASST was administered to 51 patients with alopecia areata, 53 patients with vitiligo and 51 healthy controls, and thyroid function tests and thyroid autoantibodies (anti-Tg, anti-TPO were assessed. Results: ASST was positive in 64.7% of patients with in alopecia areata, 64.2% of those with vitiligo and in 45.1% of controls. There was no statistically significant difference between the groups in terms of ASST positivity. We observed that ASST positivity had no relationship with age, anti-Tg, anti-TPO and the presence of one or both autoantibody positivity. It was seen that the frequency of ASST positivity was higher in females than in men in all groups, but it was statistically significant in alopecia areata group only. Among the all study groups, the frequency of ASST positivity was statistically significantly higher in females than in men. Conclusion: The high rates of ASST positivity in individuals with alopecia areata and vitiligo as well as in healthy control, indicate that ASST positivity does not solely exist in chronic urticaria patients. With logical regression analysis, it was shown that, having alopecia areata and being female significantly increase the risk of having ASST positivity. Therefore

Considering that alopecia affects so many people and that there is currently no scientifically proven treatment with few side effects, new drug-delivery systems able to improve alopecia therapy are urgently required. With this purpose in mind, the present study aimed to develop lipid nanoparticles (nanostructured lipid carriers with the ability to incorporate and deliver anti-alopecia active compounds (minoxidil and finasteride into the dermis and hair follicles. Lipid nanoparticles, prepared by ultrasonication method, showed mean particle sizes around 200 nm, which is sufficient for reaching the dermis and hair follicles, and zeta potential values around -30 mV, which indicates good physical stability. Over 28 days of storage, no significant variations in these parameters were observed, which indicates that all nanoformulations are stable in storage over that period. Cryo-scanning electron microscope measurements showed that all the lipid nanoparticles exhibited a spherical shape and a smooth surface regardless of their composition. Differential scanning calorimetry studies allowed the determination of phase transition temperatures and confirmed the recrystallization of the lipid nanoparticles (recrystallization index between 11% and 86%. A high loading efficiency was achieved for finasteride (between 70% and 90%, while less than 30% was

    Anecdotical experiences indicate that Koebner phenomenon (KP) can also be observed in alopecia areata (AA). The present short report gives an account of what has been observed in some patients with remitting-relapsing AA in multiple patches, in whom the phenomenon was accidentally caused by perilesional Trichogram. The almost immediate appearance of relapses of the disease (1-7 days) and their evolution can be useful to understand the physiopathology of AA and and emphasize the compelling need for a rapid and appropriate diagnosis and treatment in the acute phase of AA, even with the active participation of the patient adequately trained. The method of trichogram should be reserved for cases in which non-invasive methods such as the Pull Test or Trichoscopy are not sufficient to verify the activity of the disease.

    Pigmentation troubles have been associated in the past years with contact dermatitis and patch-testing. Contact allergy and increase of pigmentation has been associated with Tinopal; on the other hand contact allergy and depigmentation have been associated with many substances such as DNCB, squaric acid dibutylester (SADBE), carbyne, alstroemeria. Leukoderma can also be produced by irritant compound such as phenols, catechols and mercaptoamines. During 1978 and 1984 we have treated 132 patients suffering from alopecia areata with DNCB or SADBE: 51 patients have been treated by DNCB and 81 by SADBE. During the treatment 10 patients developed a leukoderma vitiligo-like localized to the areas of topical application of the allergens and to the flare-up site; one patient had an increase of pigmentation. Lesions vitiligo-like appeared 10-15 weeks after the onset of treatment. Among the patients who developed leukoderma, 4 had a personal history of vitiligo. The possible pathogenetic mechanisms are discussed.

    Congenital skin fragility is a heterogeneous disorder with epidermolysis bullosa and various skin infections as the leading causes. However, even rare diseases must be considered in the differential diagnosis of neonatal skin blistering, including some genetic syndromes with extracutaneous involvement. One such syndrome is ectodermal dysplasia due to deficiency of desmoplakin, a desmosomal protein essential for cellular cohesion in both epithelia and cardiac tissues. Desmoplakin is encoded by the DSP gene, which is localized on chromosome 6p24. Both dominant and recessive mutations in this gene have been reported to cause skin fragility and keratinization defects. We report a child born with a fragile epidermis, alopecia, thick nails, and focal hyperkeratoses on the digits and knees. She was found to have a deficiency of desmoplakin caused by compound heterozygous DSP mutations. She has gradually developed signs of a left ventricular cardiomyopathy.

    We present a follow-up case report of a 33-year-old lady with juvenile onset arthritis who developed halo naevi while on treatment with tocilizumab. This case report describes the development of halo naevi, vitiligo and diffuse alopecia areata associated with tocilizumab therapy following infection with Methicillin-resistant Staphylococcus aureus (MRSA) and Panton-Valentine leukocidin positivity. This is the first case that describes these events and supports previous theories on cellular and humoral immunity as causative factors. The regression of melanocytes during treatment with tocilizumab could also implicate IL-6 and sIL-6R as future targets in the treatment of melanoma through its direct effect of melanocytic cytotoxicity, which supports previous studies.

    Populations of wildlife species worldwide experience incidents of mass morbidity and mortality. Primary or secondary drivers of these events may escape classical detection methods for identifying microbial insults, toxin exposure, or additional stressors. In 2012, 28% of polar bears sampled in a study in the southern Beaufort Sea region of Alaska had varying degrees of alopecia that was concomitant with reduced body condition. Concurrently, elevated numbers of sick or dead ringed seals were detected in the southern Beaufort, Chukchi, and Bering seas in 2012, resulting in the declaration of an unusual mortality event (UME) by the National Oceanic and Atmospheric Administration (NOAA). The primary and possible ancillary causative stressors of these events are unknown, and related physiological changes within individual animals have been undetectable using classical diagnostic methods. Here we present an emerging technology as a potentially guiding investigative approach aimed at elucidating the circumstances responsible for the susceptibility of certain polar bears to observed conditions. Using transcriptomic analysis we identified enhanced biological processes including immune response, viral defense, and response to stress in polar bears with alopecia. Our results support an alternative mechanism of investigation into the causative agents that, when used proactively, could serve as an early indicator for populations and species at risk. We suggest that current or classical methods for investigation into events of unusual morbidity and mortality can be costly, sometimes unfocused, and often inconclusive. Advances in technology allow for implementation of a holistic system of surveillance and investigation that could provide early warning of health concerns in wildlife species important to humans.

    Hair loss is common in macaque colonies. Very little is known about the relationship between psychological stress and hair loss. We initially examined alopecia and hair cortisol concentrations in 198 (89 male) rhesus macaques from three primate centers and demonstrated replicability of our previous finding that extensive alopecia (>30% hair loss) is associated with increased chronic cortisol concentrations and significantly affected by facility. A subset of these monkeys (142 of which 67 were males) were sampled twice approximately 8 months apart allowing us to examine the hypotheses that gaining hair should be associated with decreases in cortisol concentrations and vice versa. Hair loss was digitally scored using ImageJ software for the first sample. Then visual assessment was used to examine the second sample, resulting in three categories of coat condition: (i) monkeys that remained fully haired; (ii) monkeys that remained alopecic (with more than 30% hair loss); or (iii) monkeys that showed more than a 15% increase in hair. The sample size for the group that lost hair was too small to be analyzed. Consistent with our hypothesis, monkeys that gained hair showed a significant reduction in hair cortisol concentrations but this effect only held for females. Coat condition changed little across sampling periods with only 25 (11 male) monkeys showing a greater than 15% gain of hair. Twenty (7 male) monkeys remained alopecic, whereas 97 (49 males) remained fully haired. Hair cortisol was highly correlated across samples for the monkeys that retained their status (remained alopecic or retained their hair). Am. J.

  19. The mouse as a model for understanding chronic diseases of aging: the histopathologic basis of aging in inbred mice

    Directory of Open Access Journals (Sweden)

    David Harrison

    2011-06-01

    Full Text Available Inbred mice provide a unique tool to study aging populations because of the genetic homogeneity within an inbred strain, their short life span, and the tools for analysis which are available. A large-scale longitudinal and cross-sectional aging study was conducted on 30 inbred strains to determine, using histopathology, the type and diversity of diseases mice develop as they age. These data provide tools that when linked with modern in silico genetic mapping tools, can begin to unravel the complex genetics of many of the common chronic diseases associated with aging in humans and other mammals. In addition, novel disease models were discovered in some strains, such as rhabdomyosarcoma in old A/J mice, to diseases affecting many but not all strains including pseudoxanthoma elasticum, pulmonary adenoma, alopecia areata, and many others. This extensive data set is now available online and provides a useful tool to help better understand strain-specific background diseases that can complicate interpretation of genetically engineered mice and other manipulatable mouse studies that utilize these strains.

    1991-10-01

    Paederus fuscipes (PF) dermatitis is a self-healing blistering disorder of the skin caused by a small insect belonging to genus Paederus, family Staphylinidae, order Coleoptera. Crushing PF on the skin causes acute dermatitis within 24 hours, corresponding in shape and dimensions to the area affected by the substance released (pederin). The acute vesicular lesions become crusted and scaly within a few days and heal completely in 10-12 days, with a transitory postinflammatory hypercromic patch. Twenty consecutive cases of PF dermatitis at different stages were studied histologically by routine light microscopy. The pederin causes a spectrum of histopathologic changes ranging from acute epidermal necrosis and blistering in acute stages, to marked acanthosis with mitotic figures in the late stages. PF dermatitis is an entomological model of irritant contact dermatitis, having histopathologic features of intraepidermal and subepidermal blistering, epidermal necrosis and acantholysis. The presence of some acantholytic foci, relatively far from the foci of clinically involved skin, in four of the cases considered suggests a possible role of pederin in inducing acantholysis indirectly. Acantholysis is probably caused by the release of epidermal proteases.

    Keratoconus (KC) is a corneal thinning disorder that leads to loss of visual acuity through ectasia, opacity, and irregular astigmatism. It is one of the leading indicators for corneal transplantation in the Western countries. KC usually starts at puberty and progresses until the third or fourth decade; however its progression differs among patients. In the keratoconic cornea, all layers except the endothelium have been shown to have histopathological structural changes. Despite numerous studies in the last several decades, the mechanisms of KC development and progression remain unclear. Both genetic and environmental factors may contribute to the pathogenesis of KC. Many previous articles have reviewed the genetic aspects of KC, but in this review we summarize the histopathological features of different layers of cornea and discuss the differentially expressed proteins in the KC-affected cornea. This summary will help emphasize the major molecular defects in KC and identify additional research areas related to KC, potentially opening up possibilities for novel methods of KC prevention and therapeutic intervention.

    Phyllodes tumors are rare breast tumors, accounting for less than 1% of all primary tumors of the breast. Histologically, phyllodes tumors can be divided into benign (60%), borderline (20%) and malignant (20%). The mammography examination was performed by means of a digital mammography system Giotto 3D Images; the ultrasound examination was performed through a GE Logiq P6 device and histological confirmation was possible after surgery or following the histological biopsy. We grouped the nine patients who presented clinically palpable nodules into two groups, namely: the six patients presenting histological benign results into Group I, and Group II where we included those with borderline and malignant histological results. Mammography performed in 77.7% revealed a well-circumscribed round or oval opacity or with contour lobules. Ultrasound examination was performed in all patients. Mammography and ultrasound have limitation in differentiating between benign lesion and phyllodes tumor. In the nine analyzed cases, mammographic and ultrasound examinations did not allow the differentiation into the three groups of phyllodes tumor. Histopathological examination is considered the golden standard for their diagnosis. Correlations between mammographic and microscopic aspects were inconclusive for determining the degree of differentiation, ultrasound changes could be correlated with the histopathological aspects.

  3. Histopathology for the diagnosis of infectious diseases

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available Histopathological examination of tissue biopsies for the identification of infectious organisms is a very important diagnostic tool. Conventional culture confirmation of tissue biopsies often fail to identify any pathogen as, first of all, invariably most of the tissue samples that are collected and sent for culture isolation are inappropriately collected in formalin, which prevents pathogen growth in culture media. Inadequate processing like grinding, etc. further hinders isolation. Presence of inhibitors like dead tissue debris, fibers, etc. also delays isolation. Microbiologists often lack expertise in identifying infectious pathogens directly from tissue biopsies by microscopic visualization. This review therefore acquaints microbiologists with the various methods available for detecting infectious agents by using histological stains. On histopathological examination of the tissue biopsy once, it is determined that a disease is likely to be due to an infection and has characterized the inflammatory response and hence associated microorganisms should be thoroughly looked for. Although some microorganisms or their cytopathic effects may be clearly visible on routine haematoxylin- and eosin-stained sections, additional histochemical stains are often needed for their complete characterization. Highly specific molecular techniques, such as immunohistochemistry, in situ hybridization and nucleic acid amplification, may be needed in certain instances to establish the diagnosis of infection. Through appropriate morphologic diagnoses and interlaboratory communication and collaboration, direct microscopic visualization of tissue samples can thus be very helpful in reaching a correct and rapid diagnosis.

    This study explored the perceived effects of an aesthetic care/wig programme for Italian women suffering from chemotherapy-induced alopecia. Despite advances in the treatment of many side effects of chemotherapy, alopecia remains difficult to resolve. Literature suggests that patients' reactions to alopecia and camouflaging strategies depend on their gender, individual characteristics, social context, and culture. A qualitative study was designed involving 20 patients from Sicily (Italy), who participated in an aesthetic care programme. Data were collected through semi-structured interviews, and an Interpretative Phenomenological Analysis was conducted on transcriptions. Our findings showed that, even if expected, alopecia is experienced as a traumatic event that challenges a woman's femininity, as reported by many other enquiries. Diverging from other studies, the wig is perceived as very helpful, since it camouflages baldness and reduces the 'sick aspect' related to alopecia. Patients consider their wig to be a 'friend', and it appears that through the aesthetic care programme they received support they otherwise would not have sought. We conclude that aesthetic care/wig programmes can help women affected by alopecia to cope with cancer 'stigma', especially in those rural contexts where psychosocial programmes are not frequently embraced by patients due to environmental and cultural barriers.

    Full Text Available Robotically assisted laparoscopic radical prostatectomy is a minimally invasive alternative for the treatment of prostate cancer. We report the histopathologic and shortterm PSA outcomes of 500 robotic radical prostatectomies. Five hundred patients underwent robotic radical prostatectomy. The procedure was performed via a six trocar transperitoneal technique. Prostatectomy specimens were analyzed for TNM stage, Gleason’s grade, tumor location, volume, specimen weight, seminal vesicle involvement, and margin status. A positive margin was reported if cancer cells were found at the inked specimen margin. PSA data were collected every 3 months for the first year, then every 6 months for a year, then yearly. The average preoperative PSA was 6.9 (1–90 with Gleason’s score of 5 (2%, 6 (52%, 7 (40%, 8 (4%, and 9 (2%; postoperatively, histopathologic analysis showed Gleason's 6 (44%, 7 (42%, 8 (10%, and 9 (4%; 10, 5, 63, 15, 5, and 2% had pathologic stage T2a, T2b, T2c, T3a, T3b, and T4, respectively. Positive margin rate was 9.4% for the entire series. The positive margin rate per 100 cases was: 13% (1–100, 8% (101–200, 13% (201–300, 5% (301–400, and 8% (401–500. By stage, it was 2, 4, and 2.5% for T2a, T2b, T2c tumors; 23% (T3a, 46% (T3b, and 53% (T4a. For organ-confined disease (T2, the margin rate was 2.5% and it was 31% for nonorgan-confined disease. There were a total of 47 positive margins, 26 (56% posterolateral, 4 (8.5% apical, 4 (8.5% bladder neck, 2 (4% seminal vesicle, and 11 (23% multifocal. Ninety-five percent of patients (n = 500 have undetectable PSA (<0.1 at average follow-up of 9.7 months. Recurrence has only been seen with nonorgan-confined tumors. Of those patients with a minimum follow-up of 1 year (average 15.7 months, 95% have undetectable PSA (<0.1. Our initial experience with robotic radical prostatectomy is promising.

    Full Text Available Gallbladder polyp is an increasingly common diagnosis, primarily as an abdominal ultrasound finding requested by another cause. Studies report a prevalence between 4% and 5.6%. The importance of an accurate diagnosis is related to the possibility of developing a malignancy desease. The objectvie is to correlate ultrasound and histopathologic findings in gallbladder polyp patients operated at the Hospital San Juan de Dios de La Serena. We reviewed retrospectively the medical records of patients undergoing cholecystectomy for gallbladder polyp from January 2000 to December 2010. a total of 40 patients underwent cholecystectomy for gallbladder polyp. 16 only had its tab clinic with abdominal ultrasonography report and the pathology report. 13 of them (81% were female. The mean age was 46 + / - 12 years. The reason for the ultrasonography was in 9 patients (56% abdominal pain in 3 patients (19%, a finding in asymptomatic patients, in one patient (6% biliary colic, none had jaundice, and in 3 patients (19% the cause was different. According to Abdominal ultrasound, the number of polyps was 1.1 + / - 0.3 per patient, and the average size was 5.8 + / - 1.8 mm. Histopathological examination showed the presence of polyps colesterolínicos in 11 of the 16 patients (69%.

    Full Text Available Abstract Background Little evidence exists to guide treatment of alopecia areata (AA. The current practices in treatment of children compared to adults and of progressive stages of hair loss are unknown. The objective of this study was to examine the current practices of southeastern United States dermatologists for the treatment of AA. Methods Dermatologists were sent anonymous questionnaires regarding their treatment practices by mail. Respondents' frequencies of treatment in children compared to adults and in patchy hair loss compared to widespread hair loss were compared with Wilcoxon signed-ranks tests and Friedman tests. As a secondary source, the National Alopecia Areata Registry (NAAR database was analyzed for patients' treatment histories. Results Survey results suggested that dermatologists recommend treatment less frequently for children than adults and for more advanced hair loss. NAAR data confirmed that offering no treatment for AA is relatively common. Conclusion Dermatologists' treatment of AA is inconsistent. A stronger evidence base will provide more consistent treatment options.

The etiology of the disease is still little known; the most common cause of alopecia is likely an autoimmune mechanism. Medicinal herbs (Arctium lappa roots, Sophora japonica fruits, Acorus calamus roots, Urtica dioica leaves, Humulus lupulus fruits are promising remedies for the prevention and treatment of alopecia.Methods: Anti-inflammatory properties of the phytopreparation were investigated using the following models: "rigid" inflammatory model and model of adrenalin pulmonary edema (anti-exudative activity, as well as the "cotton granuloma" model (influence on proliferative effects. Immunomodulatory properties were studied by analyzing the metabolic activity of macrophages exposed to herbal preparation as well as the secretion of monocyte-derived cytokines.Results: Intragastric administration of the herbal preparation reduced severity of the exudation phase of inflammation in the limbs of animals (37.3% and inhibited pulmonary edema (21.0%. It was demonstrated that the phytopreparation reduced the weight of the granulation-fibrous tissue by 50.6%.

    Glomuvenous malformations are a subtype of venous malformations, which present in infancy or childhood. We describe a teenage girl who presented with multiple digital glomuvenous malformations from birth. In addition, she had an epidermal naevus on the upper lip, an area of congenital alopecia of the scalp, heterochromia irides and an abdominal lipoblastoma. We are unaware of any reports of the association of multiple glomuvenous malformations with the other uncommon developmental anomalies seen in our patient, and a common link eludes us.

    We herein report a case of a 33-year-old man in remission from Hodgkin lymphoma, who presented with reduced potency and hair loss. Initial endocrine tests revealed autoimmune hypothyroidism. An MRI of his pituitary gland at onset revealed hyperplasia. He tolerated replacement endocrine therapy with good response, but with no improvement in his alopecia universalis. A repeat MRI, 6 months after his initial endocrine manipulation, showed resolution of his pituitary hyperplasia.

    The authors correlated the radiologic and histopathologic characteristics of 108 retinoblastomas in 98 patients. Calcifications were demonstrable by CT scans in 92.6% of the cases, whereas only 82% were evident upon routine histologic study. Cases of severe invasion of the optic nerve beyond the lamina cribrosa and up to the surgical margin of the nerve were detected by CT scans. Lesser degrees of invasion could not be determined by the same method. Orbital extension was also demonstrable, whereas invasion limited to the sclera was rarely accessible to CT diagnosis. Choroidal invasion was not detectable. Computerized tomography detected enlargement of the ipsilateral lacrimal gland in 17.5% of patients. This phenomenon correlates with invasion of the choroid and the optic nerve. (orig.)

    Experimental infection of fallopian tubes was produced in four sexually mature pig-tailed monkeys (Macaca nemestrina) by intratubal inoculation with serovar E or F Chlamydia trachomatis. Infection was confirmed by reisolation of the organism from both the endosalpinx and the endocervix. An antibody response to the infecting strain of C. trachomatis was demonstrated in monkey sera and in cervical secretions by the microimmunofluorescence test. A cellular immune response to C. trachomatis was shown by the in vitro lymphocyte transformation assay. Histopathologic examination of the endosalpinx following infection showed epithelial degeneration and deciliation of ciliated cells. Lymphocytic infiltration into both submucosa and mucosa was present at day 7 and approximated areas of epithelial cell degeneration. Two control monkeys remained unresponsive throughout the study. These results indicate that the pig-tailed macaque should be a suitable model for further studies of the pathogenesis of, immune responses to, and therapy for acute C. trachomatis salpingitis.

  15. Histopathological study of feline eosinophilic dermatoses.

    2001-12-01

    A retrospective study was conducted on skin specimens from 24 cats with eosinophilic granuloma complex. The specimens were stained with haematoxylin and eosin and Gallego's trichrome stain. In all specimens, flame figures and/or large foci of so-called "collagen degeneration" were detected and histopathological features were not predictive of the clinical picture. Use of the term eosinophilic dermatosis was advocated in diagnostic dermatopathology. On trichrome-stained sections, normally stained collagen fibres were identified in the middle of both flame figures and large foci of "collagen degeneration" and the debris surrounding collagen bundles showed the same tinctorial properties as eosinophil granules. Eosinophil degranulation around collagen bundles seemed to represent the major pathogenetic event in these lesions, analogous with human flame figures. The term flame figures might therefore be more accurately used to designate those foci of eosinophilic to partly basophilic debris commonly referred to as "collagen degeneration".

    Twenty-three cases of ovarian fibroma, comprising 3% of all benign tumors seen over a 20-year period, were analyzed. It was unilateral in all cases affecting more commonly the left ovary (70%). Whilst a majority of cases (77%) were encountered in the reproductive age group, the tumor was rare before the second decade. Only in 13% of cases was ascitis clinically detectable. This was not influenced by the size and weight (average of 9.3 x 10.8 x 11.1 cm and 959 g, respectively) of the tumors; a smooth-surfaced tumor was, however, associated with a greater amount of peritoneal fluid. Varying degrees of calcification in some tumors are detectable on ultrasonography and occasionally on abdominal radiography. The classical Meig's Syndrome was seldom encountered. The histopathological features, diagnostic problems and management are discussed.

    1981-12-01

    Although marine vibrio wound infections and septicemia are being reported with increasing frequency, description of the histopathologic changes has been scanty. The histologic alterations in three patients with primary marine vibrio wound infections are presented. The lesions are characterized by intense acute cellulitis of the subcutis with much tissue destruction and extension into the adjacent dermis. The superficial dermis is devitalized and lacks an inflammatory cellular infiltrate. Subepidermal noninflammatory bullae are formed. Many organisms are seen both within the areas of intense acute inflammation and in devitalized areas. Organisms and inflammation are especially oriented around vessels, with associated acute vasculitis. It is concluded that the morphologic picture in marine vibrio wound infections is nonspecific yet characteristic.

Tal distúrbio decorre de alterações neuro-hormonais e pode associar-se à introdução de novos animais e/ou crianças no ambiente. Além de mudanças de manejo e atitude para com o animal, sugere-se o emprego de ansiolíticos no tratamento da doença. A fluoxetina foi utilizada no tratamento de cinco gatos domésticos com tricotilomania, apresentando inibição do comportamento de lambedura, com repilação após dois a três meses de terapia.Feline psycogenic alopecia occurs when cats lick their hair compulsively. Stress situations play a role in this disturbance, due to changes in neurohormone mechanisms. The introduction of a new animal or baby in the household can also be associated.

    Alopecia with mental retardation (APMR) is a very rare disorder. In this study, we report on a consanguineous Pakistani family (AP91) with mild-to-moderate intellectual disability, adolescent alopecia and dentogingival abnormalities. Using homozygosity mapping, linkage analysis and exome sequencing, we identified a novel rare missense variant c.898G>A (p.(Glu300Lys)) in ITGB6, which co-segregates with the phenotype within the family and is predicted to be deleterious. Structural modeling shows that Glu300 lies in the β-propeller domain, and is surrounded by several residues that are important for heterodimerization with α integrin. Previous studies showed that ITGB6 variants can cause amelogenesis imperfecta in humans, but patients from family AP91 who are homozygous for the c.898G>A variant present with neurological and dermatological features, indicating a role for ITGB6 beyond enamel formation. Our study demonstrates that a rare deleterious variant within ITGB6 causes not only dentogingival anomalies but also intellectual disability and alopecia.

    Full Text Available Trichoscopy (hair and scalp dermoscopy is a valuable in vivo tool for the differential diagnosis of clinically frequent hair diseases. It is based on evaluation of basic structures that may be visualized with a dermascope; follicular openings, hair shafts and perifollicular epidermis. This method is useful to diagnose early androgenetic alopecia, to distinguish androgenetic alopecia from telogen effluvium, to make differential diagnosis of patchy alopecias and differentiate scarring from nonscarring alopecias. This article summarizes the current knowledge in abnormal appearances of basic structural components on trichoscopy and characteristic trichoscopic features of the most common hair diseases.

    Background:The current World Health Organization (WHO) classiifcation of nasopharyngeal carcinoma (NPC) con‑veys little prognostic information. This study aimed to propose an NPC histopathologic classiifcation that can poten‑tially be used to predict prognosis and treatment response. Methods:We initially developed a histopathologic classiifcation based on the morphologic traits and cell differentia‑tion of tumors of 2716 NPC patients who were identiifed at Sun Yat‑sen University Cancer Center (SYSUCC) (training cohort). Then, the proposed classiifcation was applied to 1702 patients (retrospective validation cohort) from hospitals outside SYSUCC and 1613 patients (prospective validation cohort) from SYSUCC. The effcacy of radiochemotherapy and radiotherapy modalities was compared between the proposed subtypes. We used Cox proportional hazards models to estimate hazard ratios (HRs) with 95% conifdence intervals (CI) for overall survival (OS). Results:The 5‑year OS rates for all NPC patients who were diagnosed with epithelial carcinoma (EC; 3708 patients), mixed sarcomatoid‑epithelial carcinoma (MSEC; 1247 patients), sarcomatoid carcinoma (SC; 823 patients), and squamous cell carcinoma (SCC; 253 patients) were 79.4%, 70.5%, 59.6%, and 42.6%, respectively (P<0.001). In mul‑tivariate models, patients with MSEC had a shorter OS than patients with EC (HR=1.44, 95% CI=1.27–1.62), SC (HR=2.00, 95% CI=1.76–2.28), or SCC (HR=4.23, 95% CI=3.34–5.38). Radiochemotherapy signiifcantly improved survival compared with radiotherapy alone for patients with EC (HR=0.67, 95% CI=0.56–0.80), MSEC (HR=0.58, 95% CI=0.49–0.75), and possibly for those with SCC (HR=0.63; 95% CI=0.40–0.98), but not for patients with SC (HR=0.97, 95% CI=0.74–1.28). Conclusions:The proposed classiifcation offers more information for the prediction of NPC prognosis compared with the WHO classiifcation and might be a valuable tool to guide treatment decisions for subtypes that are

    We reported two cases of clinically typical melasma presenting with unusual histopathologic findings. In one case, the epidermal melanocytes were markedly increased in number and protruded into the dermis, and in the other case, increased epidermal pigmentation as well as dermal melanocytosis were found. We suggested that the various treatment modalities of melasma should be applied depend on its histopathologic finding. PMID:16614533

    Full Text Available Skin ageing and gender influences on the scalp have been seldom studied. We revisited the changes in the interfollicular scalp. The study was performed on a population of 650 volunteers (300 women and 350 men for over 7 years. Three age groups were selected in both genders, namely, subjects aged 20–35, 50–60, and 60–70 years. The hair status was further considered according to nonalopecic and alopecic patterns and severity (discrete, moderate, and severe. Biopsies from the parietal area were processed for immunohistochemistry. Stromal cells were distinguished according to the presence of vimentin, Factor XIIIa, CD117, and versican. Blood and lymphatic vessels were highlighted by Ulex europaeus agglutinin-1 and human podoplanin immunoreactivities, respectively. Actinic elastosis was identified by the lysozyme coating of elastic fibres. The epidermis was explored using the CD44 variant 3 and Ki67 immunolabellings. Biplot analyses were performed. Immunohistochemistry revealed a prominent gender effect in young adults. Both Factor XIIIa+ dermal dendrocytes and the microvasculature size decreased with scalp ageing. Alopecia changes mimicked stress-induced premature senescence.

Interpretative Phenomenological Analysis was used to provide an in-depth and holistic perspective of their accounts. Semi-structured interviews were undertaken with a volunteer sample of eight respondents diagnosed with AA. Four key themes were identified: loss (self/social, concerns (physical/future, negative (emotions/thoughts, and coping styles (adaptive/maladaptive. Females experienced greater feelings of loss, were more concerned about their looks and their future, and reported more negative thoughts and emotions. Females felt angry and blamed God for their fate; males blamed both their fate and luck. Action-oriented and practical coping styles were adopted by all of them. After the realization that initial coping behaviours were ineffective, self-distraction, acceptance, and humour were used. Psychological relief followed with the practice of religion and planning for treatments to be undertaken in the future. The findings here are similar to research conducted in the West, though with more emphasis on religion. Health care providers and student counsellors need to understand the negative psychosocial consequences for adolescents living with a visible disfigurement and provide appropriate psychological and social support.

    Finasteride has proved to be relatively safe and effective in the therapeutic management of male androgenic alopecia. However, literature data report several endocrine imbalances inducing various adverse effects, which often persist after treatment cessation in the form of post-finasteride syndrome. Here we present the case of a 52-year-old man receiving finasteride (1 mg/day) who developed an uncommon adverse effect represented by generalized vitiligo 2 months after finasteride discontinuation. Associated adverse effects encountered were represented by mild sexual dysfunction (as determined by the International Index of Erectile Function, IIEF) and moderate depressive symptoms (according to DSM-V criteria), all of these manifestations aggregating within/as a possible post-finasteride syndrome. Further studies should develop and compare several therapeutic approaches, taking into account not only compounds that decrease the circulating dihydrotestosterone level but also those that could block the dihydrotestosterone receptors (if possible, compounds with selective tropism towards the skin). In addition, the possibility of predicting adverse effects of finasteride (according to hand preference and sexual orientation) should be taken into account.

    A 1-year-old castrated male cat was evaluated because of alopecia of approximately 4 to 5 months' duration as well as hyperactive behavior. It was later determined that the cat was ingesting valproic acid by eating food to which it had been added for daily administration to a child in the household who had cerebral palsy. The clinical signs slowly resolved after the source of valproic acid was removed. This emphasizes the sensitivity of cats to drugs that are commonly used in humans. It was not determined whether the clinical signs that developed in this cat were caused by an adverse reaction or from toxicosis as a result of prolonged hepatic elimination of valproic acid, which requires glucuronide metabolism for disposition. However, the cat recovered completely following removal of the drug and prevention of further exposure. This report emphasizes the importance of obtaining a careful and complete history from the owner regarding an animal and its environment. In the cat of this report, the owner had not considered the impact of the presence of the drug in the child's food.

    The endothelin receptor type A (EDNRA) signaling pathway is essential for the establishment of mandibular identity during development of the first pharyngeal arch. We report four unrelated individuals with the syndrome mandibulofacial dysostosis with alopecia (MFDA) who have de novo missense variants in EDNRA. Three of the four individuals have the same substitution, p.Tyr129Phe. Tyr129 is known to determine the selective affinity of EDNRA for endothelin 1 (EDN1), its major physiological ligand, and the p.Tyr129Phe variant increases the affinity of the receptor for EDN3, its non-preferred ligand, by two orders of magnitude. The fourth individual has a somatic mosaic substitution, p.Glu303Lys, and was previously described as having Johnson-McMillin syndrome. The zygomatic arch of individuals with MFDA resembles that of mice in which EDNRA is ectopically activated in the maxillary prominence, resulting in a maxillary to mandibular transformation, suggesting that the p.Tyr129Phe variant causes an EDNRA gain of function in the developing upper jaw. Our in vitro and in vivo assays suggested complex, context-dependent effects of the EDNRA variants on downstream signaling. Our findings highlight the importance of finely tuned regulation of EDNRA signaling during human craniofacial development and suggest that modification of endothelin receptor-ligand specificity was a key step in the evolution of vertebrate jaws.

    Alopecia areata (AA) is an organ-specific and cell-mediated autoimmune disease involving hair loss, but its pathogenesis remains poorly understood. Many autoimmune diseases are genetically associated with alleles of the human leukocyte antigen (HLA) genes within the major histocompatibility complex. Associations between AA and HLA genes were previously observed in some different ethnic groups. However, the results were inconsistent, and a primary susceptibility HLA gene and/or region has not yet been assigned for AA. The aim of this study was to evaluate whether an allele of the HLA-C locus, HLA-C*07:04, which was strongly associated with AA in Chinese Hans, could be replicated in the Japanese population. The HLA-C locus was genotyped by the SSO method using 156 AA patients and 560 healthy controls. As a consequence, among the 17 alleles detected, only two alleles, C*04:01 (OR = 2.25, CI 95 % = 1.35-3.75, P = 1.84E-03) and C*15:02 (OR = 2.52, CI 95 % = 1.37-4.64, P = 2.90E-03), were significantly associated with AA after Bonferroni correction. Further, the stratification analysis suggested that C*04:01, C*07:02, and C*15:02 represented different AA genetic risk factors in each sub-phenotype.

    Full Text Available Aim: The aim of the study was to evaluate the efficacy of platelet-rich plasma (PRP in the treatment of chronic alopecia areata (AA. Material and Methods: This is a prospective study that was conducted at Kamal Hospital, Kaushambi in which 20 patients who attended the outpatient department were enrolled for the study. All the patients had h/o patches and taken various line of treatments for a duration of 2 years. All the patients were biopsy-proven positive for AA disease. There was no randomisation done since all of them were healthy young adults. The patients′age ranged from 25 to 35 years, and none of them had any co-morbidities. Results: Of 20 patients, only one patient had a relapse. None of the patients had any side effects, and all of them tolerated the procedure well. Conclusion: We wish to conclude that PRP has a definite role in treating AA infections. However, still more long-term follow-up, studies are required for further validation of results and labelling it as a 100% cure for people suffering from AA with recurrences which are so common.

    Alopecia areata (AA) is a T-cell-mediated autoimmune disease resulting in partial or total noncicatricial hair loss. HLA class II antigens are the most important markers that constitute genetic predisposition to AA. Various life events and intense psychological stress may play an important role in triggering AA attacks. We report an unusual case series of 4 family members who had simultaneously occurring active AA lesions. Our aim was to evaluate the clinical and psychiatric features of 4 cases of active AA lesions occurring simultaneously in a family and determine HLA alleles. The clinical and psychological features of all patients were examined. HLA antigen DNA typing was performed by polymerase chain reaction with sequence-specific primers. All patients had typical AA lesions over the scalp and/or beard area. Psychological examinations revealed obsessive-compulsive personality disorder in the proband's parents as well as anxiety and lack of self-confidence in both the proband and his sister. HLA antigen types were not commonly shared with family members. These findings suggest that AA presenting concurrently in members of the same family was not associated with genetic predisposition. Shared psychological disorders and stressful life events might be the major key points in the concurrent presentation of these familial AA cases and development of resistance against treatments.

    Background Various systemic agents have been assessed for the treatment of alopecia areata (AA); however, there is a paucity of comparative studies. Objective To assess and compare cyclosporine and betamethasone minipulse therapy as treatments for AA with regard to effectiveness and safety. Methods Data were collected from 88 patients who received at least 3 months of oral cyclosporine (n=51) or betamethasone minipulse therapy (n=37) for AA. Patients with ≥50% of terminal hair regrowth in the alopecic area were considered responders. Results The responder of the cyclosporine group was 54.9% and that of the betamethasone minipulse group was 37.8%. In the cyclosporine group, patients with mild AA were found to respond better to the treatment. Based on the patient self-assessments, 70.6% of patients in the cyclosporine group and 43.2% of patients in the betamethasone minipulse group rated their hair regrowth as excellent or good. Side effects were less frequent in the cyclosporine group. Conclusion Oral cyclosporine appeared to be superior to betamethasone minipulse therapy in terms of treatment effectiveness and safety.

    Alopecia areata (AA) is a common inflammatory disease targeting the anagen-stage hair follicle. Different cytokines have been implicated in the disease profile, but their pathogenic role is not yet fully determined. We studied biopsies of pretreatment lesional and non-lesional (NL) scalp and post-treatment (intra-lesional steroid injection) lesional scalp of 6 patchy patients with AA using immunohistochemistry and gene expression analysis. Immunohistochemistry showed increases in CD3(+) , CD8(+) T cells, CD11c(+) dendritic cells and CD1a(+) Langerhans cells within and around hair follicles of pretreatment lesional scalp, which decreased upon treatment. qRT-PCR showed in pretreatment lesional scalp (compared to NL) significant increases (P hair keratins in lesional scalp, with significant upregulation of KRT35, KRT75 and KRT86 in post-treatment lesional scalp. This study shows concurrent activation of Th1 and Th2 immune axes as well as IL-23 and IL-32 cytokine pathways in lesional AA scalp and defined a series of response biomarkers to corticosteroid injection. Clinical trials with selective antagonists coupled with cytokine-pathway biomarkers will be necessary to further dissect pathogenic immunity.

    Full Text Available Bone marrow biopsy allows evaluation of cellularity, abnormal localization of immature precursors and fibrosis in myelodysplastic syndrome. It has been considered important to make diagnosis and prognosis of this disorder. The object of this study evaluated the influence of histopathological parameters, such as cellularity, erythroid/myeloid ratio, abnormal localization of immature precursors and marrow fibrosis, on survival of myelodysplastic syndrome patients. Forty-six patients, admitted from April 1985 to June 1998, and diagnosed as being myelodysplastic syndrome according to French-American-British criteria, were selected. There were 20 males and 26 females, with median age of 61 years. Forty-six bone marrow smears and 36 trephine biopsies were reviewed. Mean survival of hypocellular cases was 64.8 months and of hyper and normocellular cases was 31.8 months. Patients with predominance of erythroid hyperplasia had mean survival of 50.8 months, greater than those with predominance of myeloid hyperplasia (20.3 months. There was no statistical difference in survival of patients with or without abnormal localization of immature precursors and with or without marrow fibrosis. Bone marrow biopsy is a useful tool for the identification of parameters that influence prognosis in myelodysplastic syndrome. Hypocellularity and erythroid hyperplasia were correlated with longer survival while myeloid hyperplasia with poorer survival.

    Introduction: Chronic gastritis is inflammation of the gastric mucosa. It can be non-atrophic and atrophic. Atrophy isdefined as the loss of appropriate glands. It is frequently located in antral mucosa as consequence of Helicobacter pylori infectionand it is associated with intestinal gastric cancer. Goal: Describe histopathological and demographic characteristics of atrophicgastritis. Matherial and methods: We assessed the pathological reports of 100 patients with atrophic gastritis whose characteristicswere evaluated by using a semiquantitative scale of Sidney system of classification of gastritis. To assess the significance betweenthe incidence of various parametres we used ;~2 test. Results: We found that the difference in frequency of atrophic gastritis betweenmen and women was not statistically significant. The difference in distribution is statistically significant in favor of the antrum.Among patients who have atrophy with Helicobacterpylori infection and intestinal metaplasia and those who do not have metaplasia,it was found that the difference is highly statistically significant. Conclusion: The most frequent localisation of atrophic gastritis isantral mucosa. There is no difference between men and women in frequency of atrophic gastritis, while the aging is related with moreoften occurrence of atrophic gastritis.

    Background Diffuse panbronchiolitis (DPB) was originally and is still primarily reported in Japan, rarely in other countries. As macrolide therapy is effective for this disease with once dismal prognosis, familiarity with its clinical features is urgently needed, especially for clinicians outside Japan. The objectives of this study were to investigate the clinical features of DPB in a Chinese population and propose diagnostic procedures that will lead to increased awareness of this treatable disease among clinicians, ultimately allowing for more rapid diagnosis. Methods After a literature review, the clinical features of DPB were histopathologically confirmed in a series of 9 cases either by open lung biopsy or video-assisted thoracic surgical biopsy, resulting in the largest series of confirmed DPB cases in a non-Japanese population. Here, the cases are retrospectively described and diagnostic procedures are discussed.Conclusions Although its clinical features may vary with disease course and ethnic populations, most cases of DPB can be diagnosed or suggested according to clinical diagnostic criteria. However, underdiagnosis as a result of unfamiliarity with its clinical features and diagnostic criteria prevails. If difficulty in diagnosis arises, the diagnosis should be based on clinicopathological features and the exclusion of other diseases. Few cases can be confirmed by transbronchial biopsies; in these cases, either an open-lung biopsy or a video-assisted thoracic surgical lung biopsy should be recommended.

    Laserprobe thermal-assisted balloon, angioplasty (LTBA) has demonstrated promising initial clinical results in recanalizing stenotic or occluded superficial femoral and popliteal arteries. Over the past year we have obtained six specimens of laserprobe thermal (LT) and LTBA treated total occlusions (avg. length 12 cm) for histopathologic examination from patients who were treated for limb salvage. Three tissue specimens were obtained acutely, and one was obtained at 6, 8, and 13 days, respectively, after laser angioplasty at the time of revision for complications or failed procedures. Serial histologic sections of the treated LT segments demonstrated recanalization of atherosclerotic lesions to approximately 60-70% of the probe diameter. The LT channels were lined by a thin layer of carbonized or coagulated tissue and several layers of cell necrosis. The histology of the thermal injury was similar regardless of whether it was produced by the heated metal cap or by free argon laser energy. Stellate balloon angioplasty fractures were frequently filled with thrombus. Analysis of these human LT and LTBA specimens revealed that the thermal device produces a confined injury through the path of least resistance. Balloon dilatation produces fragmented cracks in the vessel wall, which appear to be more thrombogenic than the carbonized LT surface. With improved guidance methods, LTBA shows potential for continuing development.

    Histopathological diagnosis using Formalin-Fixed Paraffin Embedded (FFPE) tissues is essential for the prognostic and therapeutic management of cancer patients. Pathologists are being confronted with increasing demands, from both clinicians and patients, to provide immunophenotypic and gene expression data from FFPE tissues to allow the planning of personalized therapeutic regimens. Recent improvements in the protocols for pre-analysis processing of pathological tissues aim to better preserve cellular details and to conserve antigens and nucleic acid sequences. These developments have been recently patented. The international protocol for the transporting of surgical specimens from the surgical theatre to the pathology department is to immerse the specimen in formalin. The alternative method of sealing the specimens into bags under a vacuum and then cooling is a well-accepted and environmentally safe procedure that overcomes the many drawbacks linked to transfer in formalin. Importantly, RNA is notoriously poorly preserved in FFPE tissue. Due to this, successful procedures for the extraction of genetic information from archival tissues have been the object of several studies and patents. Novel molecular approaches for RT-qPCR and gene array analysis on FFPE tissues are presented here. Moreover, a major advance is reported in this study, the observation that tissue fixation in cold conditions allows a much better preservation of nucleic acid sequences.

    Osteoporosis is one of the most common disorders in postmenopausal women, affecting the quality of life and increasing the risk for fractures in minor traumas. Changes in the bone microarchitecture causes static changes in the body and affects motility. In this study, we analyzed two groups of women, one with physiological menopause and one with surgically induced menopause. The diagnosis of osteoporosis was suspected based on the clinical symptoms and confirmed by assessing bone mineral density by the dual-energy X-ray absorptiometry (DEXA). Comparing some clinical and biological aspects there was noted that a much higher percentage of women with surgically induced menopause exhibited increases in body mass index, changes in serum lipids, cholesterol, triglycerides, blood glucose, serum calcium, magnesemia and osteocalcin. In contrast, no significant differences were observed in the histopathological aspects of bone tissue examined from these two groups. In all patients, there was identified a significant reduction in the number of osteocytes and osteoblasts, the expansion of haversian channels, reducing the number of trabecular bone in the cancellous bone with wide areola cavities often full of adipose tissue, non-homogenous demineralization of both the compact bone and the cancellous bone, atrophy and even absence of the endosteal, and the presence of multiple microfractures. Our study showed that early surgically induced menopause more intensely alters the lipid, carbohydrate and mineral metabolism, thus favoring the onset of osteoporosis.

    The most common primary hepatic malignancy is hepatocellular carcinoma, which constitutes 80-85% of all malignant epithelial neoplasms originating in the liver. The second most common primary hepatic malignancy is cholangiocellular carcinoma. In recent years, remarkable progress has been made in elucidating the molecular pathology of hepatic tumors. Advances in our understanding of molecular subtypes have led to a creation of a new classification system of hepatocellular adenomas, with important genotype-phenotype correlations and easy application to routine diagnostic practice. In the field of early hepatic neoplasia, a consensus on the definition of dysplastic nodules and early hepatocellular carcinoma has been reached. Immunohistochemical detection of glypican-3 and stromal invasion are used for the differential diagnosis. A lot of problems still exist in the category of mixed hepatocellular and cholangiocellular carcinoma. Although this category is recognized in the WHO classification, confusing terminology has been generated to describe tumors with morphological features of both HCC and CC. We further specify problems and pitfalls of the differential histopathological diagnosis of liver malignant tumors.

    Autofluorescence devices are widely used to examine oral lesions. The aim of this study was to see whether there were any signs of dysplasia, parakeratosis, or mucosal inflammation in the borders of homogeneous oral leukoplakia using autofluorescence, and we also compared clinically visible extensions with those detected by autofluorescence. Twenty patients with 26 homogeneous areas of oral leukoplakia were included in the study. After the clinically visible extensions of the lesion had been marked, we took a photograph through the autofluorescence device, which showed both borders in one picture. We then used photo-editing software to measure the size of the area of leukoplakia together with the area with loss of autofluorescence. We took 3 punch biopsy specimens: one from the leukoplakia, one 2.5mm from its marked borders, and one from healthy mucosa. Seventy-eight biopsy specimens were examined by an experienced pathologist, and 95% CI calculated to assess the amount of parakeratosis. Spearman's rank correlation was used to assess the association with mucosal inflammation. Ten areas of leukoplakia were surrounded by normal green autofluorescence, and 16 were consistent with loss of autofluorescence with a mean size of 66%, which exceeded the clinically visible size of the area of leukoplakia. We calculated that there was a strong association between these entities and their surrounding areas, with loss of autofluorescence for parakeratosis. Some leukoplakias showed clinically invisible extensions during histopathological examination and autofluorescence. The technique described enables clinicians to measure the extent of these lesions beyond their visible margins. We found no dysplasia, which emphasises that autofluorescence detects non-dysplastic lesions caused by mucosal inflammation and parakeratosis.

TP53, PIK3CA, KRAS, and BRAF mutations were validated by conventional Sanger sequencing.TM-NGS yielded overlapping results on matched fresh-frozen and formalin-fixed paraffin-embedded (FFPE tissues, with a mutation detection limit of 1% for fresh-frozen high molecular weight DNA and 2% for FFPE partially degraded DNA. At least one somatic mutation was observed in all tumors tested; multiple alterations were detected in 20/35 (57% tumors. Seven cancers displayed significant differences in allelic frequencies for distinct mutations, indicating the presence of intratumor molecular heterogeneity; this was confirmed on selected samples by immunohistochemistry of p53 and Smad4, showing concordance with mutational analysis.TM-NGS is able to detect and quantitate multiple gene alterations from limited amounts of DNA, moving one step closer to a next-generation histopathologic diagnosis that integrates morphologic, immunophenotypic, and multigene mutational analysis on routinely processed tissues, essential for personalized cancer therapy.

    As pyometra is recognized as one of the main causes of disease and death in the bitch the purposes of this study were to evaluate microbiological and histopathological aspects of canine pyometra and to research the virulence factors of the E. coli isolates identifying possible risks to human health. The microbiological isolation from the intrauterine contents of 100 dogs with pyometra was carried out and the virulence factors in the E. coli strains were identified using PCR method. This study also consisted of the counting of microorganisms colonies forming units in samples of intrauterine content, tests of antimicrobial susceptibility of the E. coli isolates and the histological examination of the uterus. E. coli was the most prevalent microorganism isolated (76.6%) and 120 strains (79.5%) were positive for sfa, 86 (56.9%) were positive for cnf, 87 (57.6%) were positive for pap, 52 (34.4%) were positive for hly, 51 (33.8%) were positive for iuc and 5 (3.3%) were positive for afa genes. One observed more sensitivity of E. coli to norfloxacin, polimixin B, sulphazotrin, chloranfenicol and enrofloxacin. In 42% of the samples of uterine walls where microorganisms were isolated, the sizes of the areas of the inflammatory responses corresponded to 39–56%. Virulence factors were identified in 98.0% of the strains evaluated, demonstrating a high frequency of potentially pathogenic E. coli. It must be considered that dogs are animals that are living in close proximity to man for thousands of years and have an important role in the transmission of E. coli to other animals and to man.

    Background: Oral mucocele is the most common benign minor (accessory) salivary gland lesion, caused due to mechanical trauma to the excretory duct of the gland. Clinically they are characterized by single or multiple, soft, fluctuant nodule, ranging from the normal color of the oral mucosa to deep blue. It affects at any age and is equally present in both sexes with highest incidence in second decade of life. They are classified as extravasation or retention type. Objectives: To analyze the data between 2010 and 2011 of, clinically and histopathologically diagnosed 58 oral mucoceles for age, gender, type, site, color, cause, symptoms and dimension. Results: Oral mucoceles were highly prevalent in the age group of 15-24 years, were seen in 51.72% of males and 48.28% of females, with a ratio of 1.07:1. The extravasation type (84.48%) was more common than the retention type (15.52%). The most common affected site was lower lip (36.20%) followed by ventral surface of the tongue (25.86%). The lowest frequency was observed in floor of mouth, upper lip and palate. The maximum numbers of mucoceles were asymptomatic (58.62%), and the color of the overlying mucosa had color of adjacent normal mucosa (48.28%). It was also observed that most of the mucoceles had diameter ranging from 5 to 14 mm. The causative factors of the lesion were lip biting (22.41%), trauma (5.18%) and numerous lesions (72.41%). Conclusion: Oral Mucoceles are frequently seen in an oral medicine service, mainly affecting young people and lower lip, measuring around 5 to 14 mm and the extravasation type being the most common.

    Hirsutism, acne, alopecia, and oligo-amenorrhea are clinical expressions of hyperandrogenism, one of the most frequent endocrine disorders in women of reproductive age. Women referred to our endocrine clinics for skin symptoms of hyperandrogenism underwent a laboratory workup to evaluate hormone measurements and received antiandrogen therapy. We retrospectively analyzed the outcome of 228 consecutive patients investigated over 6 years.Patients with hirsutism had higher levels of androstenedione, dehydroepiandrosterone sulfate (DHEAS), and salivary testosterone; lower levels of sex hormone-binding globulin (SHBG); and a higher prevalence of oligo-amenorrhea than patients with alopecia, while patients with acne showed intermediate values. Hirsutism score correlated positively with androstenedione, DHEAS, and salivary testosterone, and correlated negatively with SHBG; salivary testosterone showed the highest correlation coefficient. Total testosterone was not significantly different among patients with hirsutism, alopecia, or acne, and did not significantly correlate with hirsutism score. Hirsutism and oligo-amenorrhea were the most sensitive symptoms of hyperandrogenism, and no androgenic parameter alone allowed us to identify all cases of hyperandrogenism.Patients of central European origin sought consultation with milder hirsutism scores than patients of southern European origin. There was, however, no difference in the clinical-biological correlation between these groups, arguing against differences in skin sensitivity to androgens.Polycystic ovary syndrome, defined as hyperandrogenism (hirsutism or elevated androgens) and oligo-amenorrhea, was diagnosed in 63 patients (27.6%), an underestimate compared with other reports that include systematic ovarian ultrasound studies. Neither pelvic ultrasound, used in a limited number of cases, nor the luteinizing hormone/follicle-stimulating hormone ratio helped to distinguish patients with polycystic ovary syndrome from

    To correlate the magnetic resonance (MR) images with the histopathological findings in the femoral head, the histopathology of 24 femoral heads, 15 with osteonecrosis, five with osteoarthritis and four with other hip disorders were subjected to preoperative MR imaging which demonstrated low intensity areas due to long T1 relaxation time in the femoral head. The MR signal was low where fibrovascular tissue, disintegrated fibrovascular tissue, amorphous necrotic material, bone, or cartilagenous tissue occupied the medullary space. From this study, it seems possible to predict the histopathologic changes in the femoral head using MR images. (author).

    Full Text Available Introduction: Alopecia areata (AA is disease characterized by focally, nonscarring hair loss on the scalp or other parts of the body. It affects 1-2% population of both genders and occurs at all age groups. The etiology is unknown, although most evidence supports the hypothesis that AA is a T-cell-mediated autoimmune disease of the hair follicle and that cytokines play an important role.Objective: The aim of our study was to evaluate serum concentrations of IL-1α and IL-1β in patients with AA and healthy subjects and also to asses a possible association between these cytokines and duration of the disease.Methods: Forty six patients with AA and 20 healthy controls were enrolled in the study. Serum concentrations of IL-1α and IL-1β were measured using enzyme-linked immunoassay techniques.Results: The serum level of IL-1α in patients with AA was significantly higher than that in the control group (4.34±0.86 pg/mL vs 3.66±0.35 pg/mL, respectively. IL-1β levels were greater in patients with AA than in controls (2.35±0.17 pg/mL vs 2.24±0.30, respectively but the difference was not significant (p>0.05. No correlations were found between duration of disease and the serum levels of IL-1α and IL-1β.Conclusion: Our results have demonstrated the importance of determining IL-1a concentration in serum in patients with AA. This research could contribute to the interpretation of insufficiently well known views of the pathogenesis role and significance of IL-1α in AA.

    Alopecia areata (AA) is a common skin disease that is frequently emotionally devastating. Several studies have examined the effect of AA on health-related quality of life (HRQoL). We performed a systematic review of all published studies of HRQoL in patients with AA. Eleven studies met inclusion criteria, incorporating data from 1986 patients. Patients with AA consistently demonstrate poor HRQoL scores, with greater extent of scalp involvement associated with lower HRQoL. HRQoL experienced by patients with AA is similar to that seen in patients with other chronic skin diseases including atopic dermatitis and psoriasis.

    We have developed a digital histology imaging system that has the potential to improve the accuracy of surgical margin assessment in the treatment of breast cancer by providing finer sampling and 3D visualization. The system is capable of producing a 3D representation of histopathology from an entire lumpectomy specimen. We acquire digital photomicrographs of a stack of large (120 x 170 mm) histology slides cut serially through the entire specimen. The images are then registered and displayed in 2D and 3D. This approach dramatically improves sampling and can improve visualization of tissue structures compared to current, small-format histology. The system consists of a brightfield microscope, adapted with a freeze-frame digital video camera and a large, motorized translation stage. The image of each slide is acquired as a mosaic of adjacent tiles, each tile representing one field-of-view of the microscope, and the mosaic is assembled into a seamless composite image. The assembly is done by a program developed to build image sets at six different levels within a multiresolution pyramid. A database-linked viewing program has been created to efficiently register and display the animated stack of images, which occupies about 80 GB of disk space per lumpectomy at full resolution, on a high-resolution (3840 x 2400 pixels) colour monitor. The scanning or tiling approach to digitization is inherently susceptible to two artefacts which disrupt the composite image, and which impose more stringent requirements on system performance. Although non-uniform illumination across any one isolated tile may not be discernible, the eye readily detects this non-uniformity when the entire assembly of tiles is viewed. The pattern is caused by deficiencies in optical alignment, spectrum of the light source, or camera corrections. The imaging task requires that features as small as 3.2 &mum in extent be seamlessly preserved. However, inadequate accuracy in positioning of the translation

    A 77-year-old woman born in the Dominican Republic presented with fullness of the glabella and medial eyebrows for 1 year followed by alopecia of the lateral eyebrows and frontal hairline. She stated that although she had a high hairline at baseline, it had receded in the past year. She had also noted central scalp hair thinning that started 6 years earlier. She denied all styling practices that used traction or chemical processes, although she admitted to hair dye and blow dryer use. She reported "acne" in the central face for decades and darkening of the skin on the lateral face for several years. Her medical history included hypertension, hyperlipidemia, hypothyroidism, benign paroxysmal positional vertigo, and treated breast ductal hyperplasia. Her medications were metoprolol, amlodipine, aspirin, levothyroxine, omeprazole, pravastatin, and meclizine; she denied starting any new medications within the past 2 years. Her family history was notable for androgenic pattern alopecia in a brother and a high hairline in her father. Review of systems was negative except for knee arthralgias and seasonal allergic rhinitis.

    One of the most common human autoimmune diseases, alopecia areata (AA), is characterized by sudden, often persisting and psychologically devastating hair loss. Animal models have helped greatly to elucidate critical cellular and molecular immune pathways in AA. The two most prominent ones are inbred C3H/HeJ mice which develop an AA-like hair phenotype spontaneously or after experimental induction, and healthy human scalp skin xenotransplanted onto SCID mice, in which a phenocopy of human AA is induced by injecting IL-2-stimulated PBMCs enriched for CD56+/NKG2D+ cells intradermally. The current review critically examines the pros and cons of the available AA animal models and how they have shaped our understanding of AA pathobiology, and the development of new therapeutic strategies. AA is thought to arise when the hair follicle's (HF) natural immune privilege (IP) collapses, inducing ectopic MHC class I expression in the HF epithelium and autoantigen presentation to autoreactive CD8+ T cells. In common with other autoimmune diseases, upregulation of IFN-γ and IL-15 is critically implicated in AA pathogenesis, as are NKG2D and its ligands, MICA, and ULBP3. The C3H/HeJ mouse model was used to identify key immune cell and molecular principles in murine AA, and proof-of-principle that Janus kinase (JAK) inhibitors are suitable agents for AA management in vivo, since both IFN-γ and IL-15 signal via the JAK pathway. Instead, the humanized mouse model of AA has been used to demonstrate the previously hypothesized key role of CD8+ T cells and NKG2D+ cells in AA pathogenesis and to discover human-specific pharmacologic targets like the potassium channel Kv1.3, and to show that the PDE4 inhibitor, apremilast, inhibits AA development in human skin. As such, AA provides a model disease, in which to contemplate general challenges, opportunities, and limitations one faces when selecting appropriate animal models in preclinical research for human autoimmune diseases.

    Full Text Available Background and Objectives: Alopecia areata (AA is a common, non-scarring type of hair loss, affecting approximately 2.1% of the population, many modality of treatment recommended like steroid injection, topical Immunotherapy and several systemic therapies. The aim of this study was to compare intralesional steroid injection and cryotherapyoutcomes in AA. Materials and Methods: In an analytical-descriptive study, 120 AA patients treated with intralesionalsteroid injection and 120 AA patients treated with cryotherapy were randomly selected. These two groups matched for location, duration and size of lesion and also matched for age and gender.From March 2011 to September 2013, the effect and complications of the therapies after 3, 6, 9 and 12 weeks were assessed and results were compared between the two groups. Results: Mean age of patients in steroid injection group was 30.2 ± 6.8 and in cryotherapy group was 31.8 ± 7.1. Sexual distribution in both groups was 56.7% and 43.3 % for male and female, respectively.Location of disease in 80% was in scalp and 20% was in face in both groups. The time of beginning response in steroid group was 4.13 ± 2.13 weeks and in cryotherapy group was 6.14 ± 0.29 weeks, difference between two groups was significant (P = 0.001. In term of clinical response at the end of study,in steroid group,20 patients (16.7% no response, 32 patients (26.7%, moderate response and68 patients (56.7% had a complete response, and also in cryotherapy group was, 52 patients (43.3% no response, 40 patients (33.3% moderate response and 28 patients (23.3% had a complete response. There was significant different in complete response rate and steroid injection was more effective than cryotherapy(P < 0.05. Conclusion: As the cryotherapy isa considerable treatment of AA, alsothis study proposes intralesional injection of corticosteroid,as a replacement of AA therapy; particularly the short-term complications are not significantly different.

    Alopecia areata is an autoimmune disease targeted at hair follicles with infiltrated T lymphocytes probably playing an important role in the pathogenesis. It was reported in 1985 that mechlorethamine was effective on alopecia areata patients. This has never been confirmed since. The aims of the study were to investigate the effects of mechlorethamine on balding C3H/HeJ mice affected with an alopecia-areata-like disease and to study the underlying mechanisms. Mice were treated on half of the dorsal skin with mechlorethamine and the contralateral side was treated with the vehicle ointment. After 10 wk of mechlorethamine therapy, a full pelage of hair covered the treated side in all the mice and was maintained during the study, whereas the vehicle-treated sides showed either no change or continued hair loss. Immunohistochemistry revealed that infiltrated CD4+ and CD8+ lymphocytes were eliminated from the treated side. In vitro cell viability assay showed that lymphocytes were much more sensitive to the cytotoxic effects of mechlorethamine than skin and hair follicular cells. RNase protection assay and real-time reverse transcription polymerase chain reaction showed that tumor necrosis factor alpha/beta, interleukin-12, and interferon-gamma were inhibited by mechlorethamine upon successful treatment. Our findings support that mechlorethamine restores follicular activity by selectively targeting infiltrated lymphocytes in vivo in alopecia-areata-affected mice.

    Full Text Available Total glucosides of paeony capsule (TGPC and compound glycyrrhizin tablets (CGT are plant extracts of glycosides. We conducted this study to examine the efficacy and safety of TGPC plus CGT for severe alopecia areata in children. 117 subjects were randomly allocated into TGPC plus CGT group or CGT group. For consecutive 12 months, subjects were given oral TGPC and CGT or oral CGT alone. The outcome measures included score of alopecia areata severity, effective rate, and adverse events observed in the 3rd, 6th, and 12th month. We found that the scores of alopecia areata severity of both groups were significantly reduced, and the scores of treatment group were lower than those of control group; for effective rate, there was no statistical difference between the two groups in the 3rd month, while in the 6th and 12th months the treatment group was superior compared with control group; the incidence rate of adverse events between the two groups was not statistically different, and no severe adverse events were observed. In conclusion, TGPC plus CGT appears effective and safe for severe alopecia areata in children.

    Full Text Available Abstract Objective To investigate and compare the incidence of histopathological placental lesions in mild gestational hyperglycemia, gestational diabetes and overt diabetes at term and preterm gestation. Research design and methods One-hundred-and-thirty-one placental samples were collected from Diabetes mellitus (DM positive screened patients. Two diagnostic tests, glycemic profile and 100 g oral glucose tolerance test (OGTT in parallel identified 4 groups normoglycemic, mild gestational hyperglycemia (MGH, gestational DM (GDM or overt DM (DM. Placental tissue specimens and sections from 4 groups were obtained by uniform random sampling and stained with hematoxylin-eosin. Results Placentas from MGH group presented 17 types of histopathological change and higher rates of syncytial nodes and endarteritis. GDM placentas presented only nine types of histopathological change, high rates of dysmaturity, low rates of calcification and no syncytial nodes. Overt DM placentas showed 22 types of histopathological change, 21 of which were present in the preterm period. There were histopathological similarities between MGH and DM placentas, but the former exhibited a higher incidence of endarteritis, which has been described as a "post-mortem" phenomenon. Conclusion Our results confirmed that the distinct placental changes associated with DM and MGH depend on gestational period during which the diabetic insult occurs. It may reasonably be inferred that subclinical maternal hyperglycemia during pregnancy, as showed in MGH group, is responsible for increased placental endarteritis, a postmortem lesion in the live fetus.

    Medulloblastoma (MB) is the most common central nervous system neoplasm in children and only rarely presents in the adult population. Recent molecular biology findings have characterized MB as a heterogeneous neoplasm distinguished by well-defined tumour subsets each with specific histologic and molecular features. Available immunohistochemical stains can now be used to differentiate the distinct molecular types of MB. This report analyzed the histopathologic and neuroradiologic features of two new cases of adult MB. Imaging studies in these patients revealed the morphological appearance of high-grade, well-circumscribed heterogeneous tumours with necrosis, located laterally within the posterior cranial fossa. Histopathology of resected samples demonstrated high-grade tumours (WHO grade IV) containing sheets of undifferentiated neural cells with high mitotic activity and evidence of necrosis. The histopathologic and molecular characteristics of these cases of MB are reviewed for potential applications in new molecular methods of imaging.

    Fatty liver disease includes non-alcoholic fatty liver disease (NAFLD) and alcoholic liver disease (ALD), each of which is increasing in prevalence. Each represents a histological spectrum that extends from isolated steatosis to steatohepatitis and cirrhosis. NAFLD is associated with obesity, diabetes, and insulin resistance, and is considered to be the liver manifestation of the metabolic syndrome. The pathogenesis of NAFLD and ALD involves cytokines, adipokines, oxidative stress, and apoptosis. Histopathology is the gold standard for assessing the severity of liver damage in NAFLD and ALD. We have reviewed the literature, and described and compared the epidemiology, natural disease history, pathogenesis and histopathology of NAFLD and ALD.

    Alopecia areata (AA) is a chronic, autoimmune disease. The main symptom is massive hair loss, localized or diffuse, in the scalp and the whole body. However, nails may also be involved, and brittleness, fragility and pitting can be signs of nail dystrophy in AA patients. Here, we report the case of a male patient with AA refractory to various treatments, including oral, topical and intralesional corticosteroids, immunosuppressants, cyclosporin and PUVA (oxoralen plus ultraviolet light), all interrupted due to side effects. The patient's nails had erythematous blotches (striated lunulae) with regular and superficial pitting as well as fragility (trachyonychia), and he could no longer play the guitar because of these symptoms. With patient consent, we introduced tofacitinib (5 mg twice daily), which resulted in remarkable improvements not only regarding hair regrowth but also nail changes, with function recovery within 10 months.

One deer was treated with prednisone, but the condition worsened when the dosage was decreased. Both deer were euthanatized after several months because of continued disease. The predominant histologic lesion in skin specimens was granulomatous mural folliculitis. Serologic testing and sequencing of fragments produced with a consensus polymerase chain reaction assay indicated that both deer were infected with caprine herpesvirus-2, a newly recognized member of the malignant catarrhal fever group of viruses. Disease in these deer was substantially different from that typically seen following infection with ovine herpesvirus-2, the sheep-associated malignant catarrhal fever virus. Findings in these deer establish the pathogenicity of caprine herpesvirus-2 in sika deer and illustrate the ability of this group of complex herpesviruses to cause a wide variety of clinical abnormalities in diverse species.

    The aetiology of alopecia areata (AA) is still not fully understood. However, recent clinical and experimental studies have provided insights into the pathomechanisms of AA and revealed that it is an organ-specific and cell-mediated autoimmune disease. Some triggers, such as viral infections, trauma, hormones and emotional/physical stressors, may cause activation of autoreactive T cells that target hair follicle (HF) autoantigens. In these immunological responses, cytokines and chemokines are regarded as key players that mediate the autoimmune inflammation. This results in the collapse of HF immune privilege, which is central to the pathogenesis of AA. This essay will focus on how cytokines and chemokines contribute to the immunological aspects of AA. The management of AA often remains difficult in a number of cases. Our review suggests that novel therapies for AA may involve targeting cytokines and chemokines.

    Full Text Available Although the genetic basis of androgenic alopecia has been clearly established, little is known about its non-genetic causes, such as environmental and lifestyle factors.This study investigated blood and urine heavy metals concentrations, environmental exposure factors, personal behaviors, dietary intakes and the genotypes of related susceptibility genes in patients with androgenic alopecia (AGA.Age, AGA level, residence area, work hours, sleep patterns, cigarette usage, alcohol consumption, betel nut usage, hair treatments, eating habits, body heavy metals concentrations and rs1998076, rs913063, rs1160312 and rs201571 SNP genotype data were collected from 354 men. Logistic regression analysis was performed to examine whether any of the factors displayed odds ratios (ORs indicating association with moderate to severe AGA (≥ IV. Subsequently, Hosmer-Lemeshow, Nagelkerke R(2 and accuracy tests were conducted to help establish an optimal model.Moderate to severe AGA was associated with the AA genotype of rs1160312 (22.50, 95% CI 3.99-126.83, blood vanadium concentration (0.02, 95% CI 0.01-0.04, and regular consumption of soy bean drinks (0.23, 95% CI 0.06-0.85, after adjustment for age. The results were corroborated by the Hosmer-Lemeshow test (P = 0.73, Nagelkerke R(2 (0.59, accuracy test (0.816 and area under the curve (AUC; 0.90, 0.847-0.951 analysis.Blood vanadium and frequent soy bean drink consumption may provide protect effects against AGA. Accordingly, blood vanadium concentrations, the AA genotype of rs1160312 and frequent consumption of soy bean drinks are associated with AGA.

    Full Text Available Purpose. The aim of this study is to investigate the etiology and the clinical, microbiological, histopathological, and radiological findings of acquired dacryocystoceles. Methods. In this retrospective study, we reviewed the clinical records of 10 eyes of 8 patients with dacryocystoceles who underwent external dacryocystorhinostomy (DCR surgery. Etiology, presenting symptoms and radiological findings as well as microbiological and histopathological assessment results and outcome were analyzed. Results. The records of 8 patients with dacryocystoceles were included in this study. In the histopathological evaluations of the samples collected from the lacrimal sac wall, chronic inflammation was found in all biopsied samples and fibrosis was observed in two histopathological evaluations. Computerized tomography (CT imaging showed fluid collection separated from adjacent tissues by a thin rim, corresponding to dacryocystoceles in the sac. In the microbiological culture examination of samples collected from the fluid within the cyst, no bacterial growth in 5 eyes, gram-negative bacillus growth in 3 eyes, and gram-positive cocci growth in 2 eyes were found. Conclusions. Acquired dacryocystoceles were observed extremely rarely and a definite pathogenic agent could not be identified in any of the cases, either microbiologically or histologically, whereas chronic inflammation was detected in all cases in our study.

    Full Text Available Background: Oral submucous fibrosis (OSF is a precancerous condition associated with the use of areca nut in various forms. There are very few reports to correlate the clinical stage to histopathological grading in OSF. Materials and Methods: A hospital-based study was conducted on 75 OSF cases who visited our hospital in Chennai from 2000-2003. A detailed history of each patient was recorded along with a clinical examination. Biopsy was performed for histopathological correlation. Clinical stage of the disease in terms of the ability to open one′s mouth was correlated with histopathological grading. Results: The male to female ratio of OSF cases was 6:1. All forms of areca nut products were associated with OSF. Chewing of paanmasala was associated with early presentation of OSF as compared to chewing of the betel nut. Out of 57 cases, which were in clinical stage II, 91.2% had histological grading of I and II in equal proportions and 8.8% had histological grade III. Out of 13 cases that showed a clinical stage of III, 52% showed a histological grade of II, 40% grade III and 8% grade I. Conclusion: In the present study, there was no direct correlation between clinical stages and histopathological grading. The possibility of difference in the severity and extent of fibrosis in different regions of the oral mucosa and involved muscles were considered as contributory factors for this variation.

    Histopathological grading of cancer not only offers an insight to the patients' prognosis but also helps in making individual treatment plans. Mitosis counts in histopathological slides play a crucial role for invasive breast cancer grading using the Nottingham grading system. Pathologists perform this grading by manual examinations of a few thousand images for each patient. Hence, finding the mitotic figures from these images is a tedious job and also prone to observer variability due to variations in the appearances of the mitotic cells. We propose a fast and accurate approach for automatic mitosis detection from histopathological images. We employ area morphological scale space for cell segmentation. The scale space is constructed in a novel manner by restricting the scales with the maximization of relative-entropy between the cells and the background. This results in precise cell segmentation. The segmented cells are classified in mitotic and non-mitotic category using the random forest classifier. Experiments show at least 12% improvement in F1 score on more than 450 histopathological images at 40× magnification.

    Health care is a high-risk industry, with most documented adverse incidents being associated with 'human factors' including cognitive and social skills termed 'non-technical skills'. Non-technical skills complement the diagnostic and specialist skills and professional attributes required by medical practitioners, including histopathologists, and can enhance the quality of practice and delivery of health-care services and thus contribute to patient safety. This review aims to introduce histopathologists to non-technical skills and how these pertain to everyday histopathological practice. Drawing from other domains in medicine, specifically anaesthesia and surgery, a variety of non-technical skills are identified and described in the context of histopathology to illustrate the role each plays, often collectively, in daily practice. The generic non-technical skills are defined as situation awareness, decision-making, communication, teamwork, leadership, managing stress and coping with fatigue. Example scenarios from histopathology are presented and the contributions to outcomes made by non-technical skills are explained. Consideration of these specific non-technical skills as a component in histopathology training may benefit practitioners as well as assuring patient safety.

    AIM: To compare upper gastric endoscopic and histopathologic findings in older adults in the presence and absence of B12 deficiency.METHODS: A prospective analysis of upper gastric endoscopic and gastric histopathologic findings from 30 newly identified B12-deficient patients (11 males,19 females) and 16 controls with normal B12 status (6males, 10 females) was performed. For all subjects, the indication for upper endoscopy and gastric biopsy were unrelated to B12 status. A single pathologist, blinded to B12 status, processed and interpreted the biopsy samples. Endoscopic and histopathologic findings were correlated with age, gender, hematocrit (Hct), MCV and B12 status.RESULTS: The B12-deficient group had significantly lower mean serum B12 levels compared to the controls (P<0.00005) while their mean Hct, MCV and serum albumin levels were similar. Iron deficiency (ferritinbased) was present in 21% of B12-deficient patients and intrinsic factor antibodies were present in29% (5/17) of B12-deficient patients. The endoscopic findings revealed significantly different rates of gastritis and atrophy between the B12-deficient and control groups (P= 0.017).B12-deficient patients had significantly less superficial gastritis (62% vs 94%) and significantly more atrophic gastritis (28% vs 0%) as compared to the controls (P= 0.039). Intestinal metaplasia was similar in both groups. Helicobacter pyloriinfection rates were similar in the B12-deficient patients and controls (40% vs31%).CONCLUSION: Significantly different endoscopic findings and types of gastritis could often be observed in the presence and absence of B12 deficiency. Atrophy,based on endoscopy, and atrophic gastritis, based on histopathology, suggest the presence of B12 deficiency.Gastric histopathology is not influenced by the age,gender, Hct or MCV of the patients.

    Full Text Available Aim: The aim of the study was to evaluate the surgical indications, routes of surgery and the correlation between preoperative diagnosis and histopathological examination of hysterectomy specimens. Material and Method: Medical records and histopathological findings were reviewed and analyzed retrospectively, in 422 consecutive women who underwent hysterectomy over a two-year period from 2011 to 2014. Those with confirmed malignancy before operation were excluded. Cohen kappa statistics were used to measure agreement between preoperative clinical and postoperative histopathological diagnosis which was found to be fair with %u043A value being 0.4. Results: The mean age of our patients was 51.5 ± 8 years. The abdominal route was used in 378 cases (85.5%, the vaginal route in 55 patients (12.4% and the laparoscopic-assisted vaginal hysterectomy in 9 cases (2%. Abnormal uterine bleeding (28.9 % was the most common indication for hysterectomy. The histopathology of the endometrium prior to hysterectomy was reported in 75% of the cases and the most common finding was a secretory or proliferative endometrium. Leiomyomatous uterus was the most frequently encountered pathology (43.7% followed by coexistence of leiomyoma and adenomyosis (17.4% in hysterectomy specimens. Hysterectomy specimens may be unremarkable histopathologically, most of which are vaginal hysterectomies done for uterine prolapsed (kappa=0,407. Discussion: The correlation between the preoperative clinical and the pathological diagnosis were poor in cases with abdominal pain, abnormal uterine bleeding and fibroids. But there was a high correlation in cases with adnexial mass.

    Congenital alopecia may occur either alone or in association with ectodermal and other abnormalities. On the bases of such associations, several different syndromes featuring congenital alopecia can be distinguished. Alopecia with mental retardation syndrome (APMR) is a rare autosomal recessive disorder, clinically characterized by total or partial hair loss and mental retardation. In the present study, a five-generation Pakistani family with multiple affected individuals with APMR was ascertained. Patients in this family exhibited typical features of APMR syndrome. The disease locus was mapped to chromosome 3q26.2-q26.31 by carrying out a genome scan followed by fine mapping. A maximum two-point logarithm of odds (LOD) score of 2.93 at theta=0.0 was obtained at markers D3S3053 and D3S2309. Multipoint linkage analysis resulted in a maximum LOD score of 4.57 with several markers, which supports the linkage. The disease locus was flanked by markers D3S1564 and D3S2427, which corresponds to 9.6-cM region according to the Rutgers combined linkage-physical map of the human genome (build 35) and contains 5.6 Mb. The linkage interval of the APMR locus identified here does not overlap with the one described previously; therefore, this locus has been designated as APMR2.

    We conducted a 16-week double-blind randomized controlled single-center trial to evaluate the safety and efficacy of dermal rice bran supercritical CO2 extract (RB-SCE) in the treatment of androgenic alopecia. Fifty alopecia patients were randomly assigned to the experimental and placebo groups. The experimental group received a dermal application of 0.5% RB-SCE (8 mL/d) to the head skin for 16 weeks while the control group received a dermal application of placebo. Changes in hair count, diameter, and density were evaluated with a Folliscope(®). Patient satisfaction was evaluated via questionnaire and clinical photographs were rated by dermatologists. The results showed that RB-SCE significantly increased hair density and hair diameter in male subjects. Patient satisfaction and the evaluation of photographs by dermatologists also confirmed the effectiveness of RB-SCE in the treatment of alopecia. No adverse reactions related to RB-SCE were reported. Therefore, RB-SCE shows promise for use in functional cosmetics and pharmaceuticals.

    Histopathological changes in kidney cortex, as observed by light microscopy, are related to cadmium concentration in kidney cortex from 69 normal Swedish horses. Cadmium concentrations in kidney ranged from 11 to 186 ..mu..g Cd/g wet wt with an average of 60 ..mu..g Cd/g, which is considerably higher than those normally found in humans. The microscopical changes were rated and related to cadmium concentrations in kidneys by dose-response curves. A relationship existed between frequency of morphological changes and cadmium concentration in the renal cortex. There was no obvious relationship between age and frequency of histopathological changes. This indicates that in horse kidneys morphological changes occur at cadmium concentrations which are lower than the tentative critical level for humans of 200 ..mu..g Cd/g. It is concluded that horses constitute a population at risk for environmental cadmium contamination.

    The in situ observation on the tissues, such as histopathology, immunohistochemistry (IHC), immunofluorescence (IF), and in situ hybridization (ISH), is one of the most important methods in the biomedical scientific research. In this chapter we introduce the most often used methods-hematoxylin and eosin (H&E) and double IF staining. H&E staining is used for general morphology by which the different pathological types of breast lesions are identified. The double IF staining is often used to study the protein-protein interaction on tissues for signaling mechanisms. This chapter also includes the histopathology of primary or simplified breast lesion types that is essential for applying the above methods and the reclassification of breast cancers by molecular markers.

    Accessing information of interest in collections of histopathology images is a challenging task. To address such issue, previous works have designed searching strategies based on the use of keywords and low-level features. However, those methods have demonstrated to not be enough or practical for this purpose. Alternative low-level features such as cell area, distance among cells and cell density are directly associated to simple histological concepts and could serve as good descriptors for this purpose. In this paper, a statistical model is adapted to represent the distribution of the areas occupied by cells for its use in whole histopathology image characterization. This novel descriptor facilitates the design of metrics based on distribution parameters and also provides new elements for a better image understanding. The proposed model was validated using image processing and statistical techniques. Results showed low error rates, demonstrating the accuracy of the model.

    White-nose syndrome, associated with the fungal skin infection geomycosis, caused regional population collapse in bats in North America. Our results, based on histopathology, show the presence of white-nose syndrome in Europe. Dermatohistopathology on two bats (Myotis myotis) found dead in March 2010 with geomycosis in the Czech Republic had characteristics resembling Geomyces destructans infection in bats confirmed with white-nose syndrome in US hibernacula. In addition, a live M. myotis, biopsied for histopathology during hibernation in April 2011, had typical fungal infection with cupping erosion and invasion of muzzle skin diagnostic for white-nose syndrome and conidiospores identical to G. destructans that were genetically confirmed as G. destructans. ??

    Prediction of prognosis in colorectal cancer is vital for the choice of therapeutic options. Histopathological factors remain paramount in this respect. Factors such as tumor size, histological type and subtype, presence of signet ring morphology and the degree of differentiation as well as the presence of lymphovascular invasion and lymph node involvement are well known factors that influence outcome. Our understanding of these factors has improved in the past few years with factors such as tumor budding, lymphocytic infiltration being recognized as important. Likewise the prognostic significance of resection margins, particularly circumferential margins has been appreciated in the last two decades. A number of molecular and genetic markers such as KRAS, BRAF and microsatellite instability are also important and correlate with histological features in some patients. This review summarizes our current understanding of the main histopathological factors that affect prognosis of colorectal cancer.

    The adult form of Taenia taeniaeformis is found in the intestine of the cat and cheetah. The larva form is called Strobilocercus fasciolaris and is found in rodents such as mice and rats. Our objective was to draw attention to that rare zoonosis, since it has already been reported in the literature as strobilocercosis in humans. During an experimental animal study conducted at Inonu University, some unexpected cystic formations were found in the livers of nine 6-8-month-old healthy white mice, which affected the conducted study negatively. These cystic formations were examined histopathologically. Prepared sections were stained with haemotoxylin eosin, periodic acid-Schiff and Masson trichrome stains, and examined by light microscopy. Strobilocercus fasciolaris larvae that curled towards cyst cavity and their hooks were seen. Plasma cells, macrophage, focus of eosinophilic infiltration and fibroblastic connective tissue were simultaneous found. In this paper, histopathological changes in intermediate hosts caused by Strobilocercus fasciolaris and other cestod larvae have been discussed.

    Full Text Available Trichoepithelioma is a well-recognized hamartoma of hair germ clinically presenting as solitary or multiple papules. Uncommonly, it may present as a large solitary lesion, termed as giant solitary trichoepithelioma (GST. A 50-year old man presented with a large, pedunculated mass over the root of nose obstructing visual field. It was excised and sent for histopathological examination. H&E staining revealed in addition to characteristic features of trichoepithelioma, a desmoplastic hypocellular stroma. After taking into account the clinical and histopathological features, a diagnosis of GST was made. This case is the first case to the best of authors’ knowledge describing desmoplastic stroma in a case of GST. It is also noteworthy because it reports the largest GST described so far over the nose.

    Full Text Available Hedera helix  is widely used to treat bronchial asthma for many years. However, effects of this herb on lung histopathology is still far from clear. We aimed to determine the effect of oral administration of Hedera helix on lung histopathology in a murine model of chronic asthma.BALB/c  mice  were  divided  into  four  groups;   I  (Placebo,  II  (Hedera  helix, III (Dexamethasone and IV (Control. All mice except controls were sensitized and challenged with ovalbumin. Then, mice in group I received saline, group II 100 mg/kg Hedera helix and group III 1 mg/kg  dexamethasone via orogastic gavage once daily for one week. Airway histopathology was evaluated by using light and electron microscopy in all groups.Goblet  cell numbers and thicknesses of basement membrane were found  significantly lower in group II, but there was no statistically significant difference in terms of number of mast cells, thicknesses of epithelium and subepithelial smooth muscle layers between group I and II. When Hedera helix and dexamethasone groups were compared with each other, thickness of epithelium, subepithelial muscle layers, number of mast cells and goblet cells of group III were significantly ameliorated when compared with the group II.Although Hedera helix administration reduced only goblet cell counts and the thicknesses of basement membrane  in the  asthmatic airways, dexamethasone ameliorated all histopathologic parameters except thickness of  basement  membrane  better  than  Hedera helix.

Method: 177 cases diagnosed with intracranial meningioma were retrospectively examined in our clinic between the years of 2007-2012 and their age, sex, tumor localization, and histopathologic properties were analyzed. Results: 74.6% of 177 intracranial meningioma cases were females, 25.4% were males and the ratio of Male/Female was found 3.4/10. The age interval of the cases was between 12-105 years old. It was most frequently seen at the interval of 51-60. In histopathologic examination, 163 cases (92.1% were noted as WHO Grade I, 11 cases (6.2% were WHO Grade II, and 3 cases (1.7% were WHO Grade III. While meningotelial transitional, and psammomatous type was the most frequently seen in WHO Grade I, atypical meningioma was only dominant in Grade II. In WHO Grade II and III cases, dominance of the male sex was present. While 88.1% of the cases had supratentorial localization, 11.9% had infratentorial localization, 1 case had lateral ventricle localization. In 7 cases (3.9% of the series, multiple meningiomas were determined. Conclusion: In a series of 177 cases, intracranial meningiomas were seen between 51-60 years old and its most frequent localization was convexity. While Grade I cases were seen in the female sex, dominance of the male sex was present in Grade II and III cases. Additionally, all of multiple meningiomas detected were female cases. Meningotelial meningiomas constitute the most commonly seen subtype among Grade I cases.

    Intravascular papillary endothelial hyperplasia (Masson's tumor) is a benign lesion of the skin and subcutaneous tissue consisting of a reactive proliferation of endothelial cells with papillary formations related to a thrombus. It poses a diagnostic challenge as the clinical signs and symptoms are nonspecific and may mimic a soft tissue sarcoma. The diagnosis is based on histopathology. Here we report two cases of Masson's hemangioma occurring on the upper lip and on the left hand.

    Full Text Available ABSTRACT Purpose: Conjunctival tissue tumors have a varied presentation, and few series studies on pediatric patients have been published. The objective of this paper is to report the histopathologic diagnoses (spanning over 1988-2013 of conjunctival tumors in children younger than 14 years. Methods: We conducted a retrospective, descriptive, and observational study by reviewing the database of all children in whom a conjunctival tumor was surgically removed at Hospital de Ojos y Oídos "Dr. Rodolfo Robles V.," Benemérito Comité Pro Ciegos y Sordos de Guatemala. The data pertaining to gender, age, and histopathologic diagnosis of all cases was collected. The same ocular pathologist made all diagnoses. Results: One hundred sixty-five cases were found, with a mean age of 7.88 years, being 91 (55.15% male subjects. Melanocytic lesions were the most common tumors found (30.91% of cases, with only one case (0.60% being malignant. Conclusions: Melanocytic lesions were the most common tumors found, and of all the cases, only one was malignant; this was in a patient with xeroderma pigmentosum. These findings are consistent with those reported in other studies regarding the frequencies of the histopathology of conjunctival tumors in the pediatric population.

    Equine pastern vasculitis is clinically challenging and the underlying aetiopathogenesis is unclear. The aims of this retrospective study were to establish histopathological criteria for pastern vasculitis, to look for an underlying cause, to investigate whether the histopathological lesions are associated with a distinct clinical picture, to assess if and how the clinical picture varies, and to determine the treatment response. Skin biopsies and clinical data from 20 horses with a diagnosis of vasculitis of the distal extremities were investigated and histology was compared to biopsies from healthy horses. It was concluded that intramural inflammatory cells, leukocytoclasia with nuclear dust, thickening and oedema of the vessel walls, and microhaemorrhages are highly specific histological findings in equine pastern vasculitis. Based on the feedback from the clinicians, the lesions were mostly seen on the lateral and medial aspects of un-pigmented legs. Lesions in white skin were characterised by exudation and crusts, whereas those in pigmented skin were alopecic and characterised by scaling. The response to treatment was poor and the prognosis guarded. No association was found between any of the histopathological findings and a distinct clinical picture. An underlying cause of equine pastern vasculitis could not be identified. Considering the large number of confounding factors, the causative agents are difficult to identify, but may involve drugs or a hypersensitivity reactions to yet unknown antigens.

    Hysterectomy, the most common gynecological surgery, provides a definitive cure to various diseases like DUB (dysfunctional uterine bleeding), leiomyoma, adenomyosis, chronic pelvic pain, prolapse, and malignancy. However, with advent of effective medical and conservative treatment modalities for nononcological causes it is now posing question mark on justification of hysterectomy. Therefore, an audit is required to assess the correlation between preoperative diagnosis and histopathological examination of specimen for justification of the procedure. In this study over period of one year (April 2013 to March 2014) 373 hysterectomies specimens were received in the department of pathology for nononcological causes. The age of patients ranged from 22 to 85 years with mean 45 ± 9.2 years. All cases were divided into five categories on the basis of age and audit was done. In this study the most common finding was leiomyoma (43.7%) followed by adenomyosis (19.3%). Almost 50% of hysterectomies causes were justified as preoperative diagnosis matched with histopathology. Cohen kappa statistics were used to measure agreement between preoperative and postoperative histopathological diagnosis which was found to be fair with κ value being 0.36. This study highlights that regular audit of surgeries can help improve quality of health care services and provide safe conservative option to patients.

    Labeling a histopathology image as having cancerous regions or not is a critical task in cancer diagnosis; it is also clinically important to segment the cancer tissues and cluster them into various classes. Existing supervised approaches for image classification and segmentation require detailed manual annotations for the cancer pixels, which are time-consuming to obtain. In this paper, we propose a new learning method, multiple clustered instance learning (MCIL) (along the line of weakly supervised learning) for histopathology image segmentation. The proposed MCIL method simultaneously performs image-level classification (cancer vs. non-cancer image), medical image segmentation (cancer vs. non-cancer tissue), and patch-level clustering (different classes). We embed the clustering concept into the multiple instance learning (MIL) setting and derive a principled solution to performing the above three tasks in an integrated framework. In addition, we introduce contextual constraints as a prior for MCIL, which further reduces the ambiguity in MIL. Experimental results on histopathology colon cancer images and cytology images demonstrate the great advantage of MCIL over the competing methods.

    Hydroxylated fullerenes are reported to be very strong antioxidants, acting to quench reactive oxygen species, thus having strong potential for important and widespread applications in innovative therapies for a variety of disease processes. However, their potential for toxicological side effects is still largely controversial and unknown. Effects of hydroxylated fullerenes C60(OH)24 on the fathead minnow (Pimephales promelas) were investigated microscopically after a 72-hour (acute) exposure by intraperitoneal injection of 20 ppm of hydroxylated fullerenes per gram of body mass. Cumulative, semi-quantitative histopathologic evaluation of brain, liver, anterior kidney, posterior kidney, skin, coelom, gills and the vestibuloauditory system revealed significant differences between control and hydroxylated fullerene-treated fish. Fullerene-treated fish had much higher cumulative histopathology scores. Histopathologic changes included loss of cellularity in the interstitium of the kidney, a primary site of haematopoiesis in fish, and loss of intracytoplasmic glycogen in liver. In the coelom, variable numbers of leukocytes, including many macrophages and fewer heterophils and rodlet cells, were admixed with the nanomaterial. These findings raise concern about in vivo administration of hydroxylated fullerenes in experimental drugs and procedures in human medicine, and should be investigated in more detail.

    In histopathological image analysis, feature extraction for classification is a challenging task due to the diversity of histology features suitable for each problem as well as presence of rich geometrical structures. In this paper, we propose an automatic feature discovery framework via learning class-specific dictionaries and present a low-complexity method for classification and disease grading in histopathology. Essentially, our Discriminative Feature-oriented Dictionary Learning (DFDL) method learns class-specific dictionaries such that under a sparsity constraint, the learned dictionaries allow representing a new image sample parsimoniously via the dictionary corresponding to the class identity of the sample. At the same time, the dictionary is designed to be poorly capable of representing samples from other classes. Experiments on three challenging real-world image databases: 1) histopathological images of intraductal breast lesions, 2) mammalian kidney, lung and spleen images provided by the Animal Diagnostics Lab (ADL) at Pennsylvania State University, and 3) brain tumor images from The Cancer Genome Atlas (TCGA) database, reveal the merits of our proposal over state-of-the-art alternatives. Moreover, we demonstrate that DFDL exhibits a more graceful decay in classification accuracy against the number of training images which is highly desirable in practice where generous training is often not available.

    The histopathological examination of tissue specimens is essential for cancer diagnosis and grading. However, this examination is subject to a considerable amount of observer variability as it mainly relies on visual interpretation of pathologists. To alleviate this problem, it is very important to develop computational quantitative tools, for which image segmentation constitutes the core step. In this paper, we introduce an effective and robust algorithm for the segmentation of histopathological tissue images. This algorithm incorporates the background knowledge of the tissue organization into segmentation. For this purpose, it quantifies spatial relations of cytological tissue components by constructing a graph and uses this graph to define new texture features for image segmentation. This new texture definition makes use of the idea of gray-level run-length matrices. However, it considers the runs of cytological components on a graph to form a matrix, instead of considering the runs of pixel intensities. Working with colon tissue images, our experiments demonstrate that the texture features extracted from "graph run-length matrices" lead to high segmentation accuracies, also providing a reasonable number of segmented regions. Compared with four other segmentation algorithms, the results show that the proposed algorithm is more effective in histopathological image segmentation.

    Nonalcoholic fatty liver disease (NAFLD), a hepatic manifestation of metabolic syndrome, is the most common chronic liver disease, and the prevalence is rapidly increasing worldwide. Nonalcoholic steatohepatitis (NASH), the severe form of NAFLD, can progress to liver cirrhosis and hepatocellular carcinoma (HCC). Although noninvasive clinical scores and image-based diagnosis for NAFLD have improved, histopathological evaluation of biopsy specimens remains the gold standard for diagnosing NAFLD/NASH. Steatosis, lobular inflammation, and hepatocellular ballooning are all necessary components for the diagnosis of NASH; fibrosis is also typically observed. Other histopathological abnormalities commonly observed in NASH include hepatocellular glycogenated nuclei, lipogranulomas, and acidophil bodies. The characteristics of pediatric NAFLD/NASH differ from adult NAFLD/NASH. Specifically, steatosis and portal inflammation are more severe in pediatric NAFLD, while intralobular inflammation and perisinusoidal fibrosis are milder. Although interobserver agreement for evaluating the extent of steatosis and fibrosis is high, agreement is low for intralobular and portal inflammation. A recently reported histological variant of HCC, steatohepatitic HCC (SH-HCC), shows features that resemble non-neoplastic steatohepatitis, and is thought to be strongly associated with underlying NASH. In this report, we review the histopathological features of NAFLD/NASH.

    Full Text Available Background. Pyogenic granuloma is a reactive tumor-like lesion commonly affecting the oral cavity. These lesions usually appear as localized solitary nodule with a sessile or pedunculated base and colour varying from red, purplish, or pink, depending on the vascularity of the lesion. Pyogenic granuloma shows predilection for gingiva and is usually slow growing, but at times it shows rapid growth. The natural course of this lesion can be categorized into three distinct phases, namely, (i cellular phase, (ii capillary phase/vascular phase, and (iii involutionary phase. Histopathologically, pyogenic granuloma is classified into lobular capillary hemangioma (LCH and non-lobular capillary hemangioma (non-LCH. Case Presentation. In this series, four cases (varied age groups and both genders of pyogenic granuloma showing varying histopathological presentation in relation to its clinical course have been described. The lesion in its early phase reveals diffuse endothelial cells, with few budding into capillaries. Among the capillary phase, the LCH type shows numerous blood vessels organized into lobular aggregates whereas the non-LCH type does not show any such organization and resembles granulation tissue. The involutionary phase shows healing of the lesion and is characterized by extensive fibrosis in the connective tissue. Conclusion. In conclusion, knowledge of the various histopathological presentation of this lesion is necessary for proper identification.

    Abnormal uterine bleeding is a common presenting complaint in gyanecology out patient department. Histopathological evaluation of the endometrial samples plays a significant role in the diagnosis of abnormal uterine bleeding. This study was carried out to determine the histopathological pattern of the endometrium in women of various age groups presenting with abnormal uterine bleeding. Endometrial biopsies and curettings of patients presenting with abnormal uterine bleeding was retrospectively studied. A total of 403 endometrial biopsies and curettings were analyzed. The age of the patients ranged from 18 to 70 years. Normal cyclical endometrium was seen in 165 (40.94%) cases, followed by 54 (13.40%) cases of disordered proliferative endometrium and 44 (10.92%) cases of hyperplasia. Malignancy was seen in 10 (2.48%) cases. Hyperplasia and malignancy were more common in the perimenopausal and postmenopausal age groups. Histopathological examination of endometrial biopsies and curettings in patients presenting with abnormal uterine bleeding showed a wide spectrum of changes ranging from normal endometrium to malignancy. Endometrial evaluation is specially recommended in women of perimenopausal and postmenopausal age groups presenting with AUB, to rule out a possibility of any preneoplastic condition or malignancy.

    Alopecia areata (AA) affects anagen hair follicles, resulting in non-scarring hair loss. Since introduced by Huang et al., superficial cryotherapy has been accepted as a considerable primary therapeutic modality for AA. The aim of this study was to objectively clarify the therapeutic efficacy and safety of superficial hypothermic cryotherapy for treatment of AA. Medical records of 353 patients from 1993 to 2014 were retrospectively analyzed. According to the response to the superficial cryotherapy, patients were categorized into four groups: "marked", "partial", "poor" and "no recovery". The marked and partial recovery groups were considered as responders. The proportions of the responders among patient subgroups which were defined by various patients, disease, and treatment factors were compared. Of the patients, 60.9% were classified as responders after 3 months of superficial hypothermic cryotherapy. The proportion of the responders were higher when the treatment interval was 2 weeks or less and in the incipient disease stage, with statistical significance. No severe side-effects other than mild pain and pruritus were reported. In conclusion, superficial cryotherapy is an effective and safe therapeutic modality for AA. Especially when the treatment interval is 2 weeks or less and in the first occurrence of the disease, the therapeutic outcome is superior.

  1. Sterol intermediates of cholesterol biosynthesis inhibit hair growth and trigger an innate immune response in cicatricial alopecia.

    Directory of Open Access Journals (Sweden)

    Sreejith P Panicker

    Full Text Available Primary cicatricial alopecia (PCA is a group of inflammatory hair disorders that cause scarring and permanent hair loss. Previous studies have implicated PPARγ, a transcription factor that integrates lipogenic and inflammatory signals, in the pathogenesis of PCA. However, it is unknown what triggers the inflammatory response in these disorders, whether the inflammation is a primary or secondary event in disease pathogenesis, and whether the inflammatory reaction reflects an autoimmune process. In this paper, we show that the cholesterol biosynthetic pathway is impaired in the skin and hair follicles of PCA patients. Treatment of hair follicle cells with BM15766, a cholesterol biosynthesis inhibitor, or 7-dehydrocholesterol (7-DHC, a sterol precursor, stimulates the expression of pro-inflammatory chemokine genes. Painting of mouse skin with 7-DHC or BM15766 inhibits hair growth, causes follicular plugging and induces the infiltration of inflammatory cells into the interfollicular dermis. Our results demonstrate that cholesterologenic changes within hair follicle cells trigger an innate immune response that is associated with the induction of toll-like receptor (TLR and interferon (IFN gene expression, and the recruitment of macrophages that surround the hair follicles and initiate their destruction. These findings reveal a previously unsuspected role for cholesterol precursors in PCA pathogenesis and identify a novel link between sterols and inflammation that may prove transformative in the diagnosis and treatment of these disorders.

    Introduction: The purpose of this study is to determine the etiologies, histopathology and MDCT findings of children with fulminant hepatic failure admitted to our institution. Materials and methods: Between June 2004 and November 2006, 15 children with fulminant hepatic failure who underwent MDCT were included retrospectively in this study. Twelve patients had liver biopsies. The patients were divided into three groups as hyperacute (Group I), acute (Group II) and subacute (Group III) depending on onset of hepatic encephalopathy. Results: Hepatitis A in 4 patients, non-A, non-E hepatitis in 4; mushroom poisoning in 3; fulminant Wilson's disease in 2; autoimmune hepatitis in 1; and both hepatitis B and toxic hepatitis (with leflunomide treatment) in 1 patient were detected. MDCT of all three groups revealed diffuse reduction in hepatic attenuation in 11 patients; ascites in 9; periportal edema in 6; edema of gallbladder wall in 6; splenomegaly in 6; heterogeneous hepatic parenchyma in 6; hepatomegaly in 3; irregular contours of liver in 2; multiple micronodules in 1 and necrotic areas and regeneration in liver parenchyma in 2 patients. Histopathologic evaluation of liver biopsies showed massive hepatic necrosis, inflammatory cell infiltration and ductular proliferation in 8 patients, periportal edema in 6, edema of gallbladder wall in 5, regenerating nodules and fibrous septa consistent with cirrhotic pattern in 2, and regenerating nodules and necrotic areas in 2 patients. Conclusion: The most common MDCT findings in fulminant hepatic failure were diffuse reduction in hepatic attenuation and ascites. Massive hepatic necrosis was the most common histopathologic finding.

    Acral lentiginous melanoma is a rare variant of melanoma that is associated with a relatively low survival rate. The latter is partly due to the advanced stage in which the tumor is usually diagnosed. The diagnostic delay is mainly due to difficulties in identifying the very early histopathological signs of acral melanoma. The current article is a review of diagnostic clues, concepts, and definitions from the literature, as well as illustrating examples from our own archives. We have sought to provide an article that can be easily consulted in difficult cases of acral lentiginous melanoma.

    Odontomas and dentigerous cysts are common findings for practicing dental professionals. However, simultaneous occurrence of pathologies like odontoma and dentigerous cyst are uncommon and their diagnosis based on the radiographic appearance alone is a challenge to overcome. They together are a potential for complications like attaining large size, root resorption, destruction of the jaw bones and sometimes neoplastic changes like ameloblastoma. This paper presents a case of complex odontoma associated with dentigerous cyst in relation to a retained deciduous tooth in the maxillary anterior region and confirming its diagnosis histopathologically.

    The histopathological response of male game farm mallards fed lead, three types of plastic-coated lead, two lead-magnesium alloys, iron, copper, zinc-coated iron, and molybdenum-coated iron shot was studied. Mallards fed lead, plastic-coated lead, or lead-magnesium alloy shot developed a similar pathological response, including the formation of acid-fast intranuclear inclusion bodies in the kidneys. Birds fed iron or molybdenum-coated iron shot developed hemosiderosis of the liver. Two of four mallards fed zinc-coated iron shot also developed hemosiderosis of the liver. No lesions were found in mallards fed copper shot.

    Pathology occurring during reproduction and larval development represents an important part of the life cycle of fish, and the diseases that affect eggs and larvae often result in significant losses. However, mortality during this period is frequently ignored or poorly researched as the temptation is to replace the losses rather than investigate the causes. A histopathology workshop organised at the newly refurnished laboratory within the Danish Veterinary School was an opportunity to discuss the pathology of selected diseases associated with Reproductive and Early Life Stages Pathology. Several people also kindly provided reference slides.

    Elastoma is a connective tissue nevus characterized by changes in elastic fibers. It can be congenital or acquired, and is usually diagnosed before puberty. Associated with osteopoikilosis, it is known as Buschke-Ollendorff syndrome. Histopathology with specific staining for elastic fibers is critical for a diagnostic conclusion. This report describes the case of a 7-year-old male patient with lesions diagnosed as elastoma, with absence of bone changes in the radiological imaging. This study aims to report the clinical presentation and histological examination of such unusual disease.

    Full Text Available Polymorphous low-grade adenocarcinomas (PLGA are distinctive salivary gland neoplasms, with an almost exclusive propensity to arise from the minor salivary glands. PLGA frequently manifests as an asymptomatic, slow-growing mass within the oral cavity, which must be separated from adenoid cystic carcinoma and benign mixed tumor for therapeutic and prognostic considerations. We report a case of a 67-year-old male, who presented with a long-standing mass in the palate. This lesion was diagnosed as PLGA based on histopathological findings, which was further confirmed by the immunohistochemical marker.

    Full Text Available Ovarian steroid cell tumours (not otherwise specified are rare neoplasms of the ovary and are classified under lipid cell tumours. Their diagnosis can be considered as one of exclusion. Histopathologically, the tumour should carefully be evaluated for microscopic features of malignancy, but it is essential for the clinician and the pathologist to remember that in these tumours, pathologically benign histomorphology does not exclude the possibility of clinically malignant behaviour. Our case study focuses on the comparative findings in a postmenopausal female diagnosed with an ovarian steroid tumour (not otherwise specified. A careful correlation between clinical and surgical evaluation and microscopic analysis is necessary, as is a regular followup.

    Full Text Available Background: Abnormal uterine bleeding is one of the commonest complaints in women and when it occurs without organic lesions like tumor, inflammation, it is called as dysfunctional uterine bleeding. Aim of current study was to find out the histopathological pattern of endometrium in Abnormal Uterine Bleeding (AUB also to study organic causes of AUB. Methods: Specimens received as endometrial curettage and hysterectomy specimens were studied followed by correlation of histopathology with age and clinical presentation. Results: The patients were mainly from the age group of 30-49 years (74.24%. The most common menstrual disorder was menorrhagia (46.86%. In dysfunctional uterine bleeding the most common histological pattern of endometrium includes proliferative endometrium (22.8% followed by endometrial hyperplasia (19.40%, atrophic endometrium (7.16%, secretory endometrium (5.97%, irregular shedding [1.80%], irregular ripening (1.20% and anovulatory endometrium (0.59%. Organic lesions encountered in AUB cases were leiomyoma (17.92%, endometrial polyp (1.79%, endometrial carcinoma (1.50%, endometriosis (0.59% and choriocarcinoma (0.29%. Conclusion: It is important to know the histological pattern of the endometrium like proliferative endometrium, endometrial hyperplasia, atrophic endometrium, secretory endometrium, irregular ripening and shredding and organic lesions in patients diagnosed as AUB in different age groups since recognition of these conditions will help and will avoid further complications.

    2004-07-01

    The aim of the study is: 1) A sequential description of the clinical course of acute radiation proctitis during pelvic RT. 2) A sequential description of the rectal mucosal histopathology during pelvic RT as a possible substrate for clinical toxicity. 3) To assess the mucosal protease activity during RT as a possible explanation of the observed tissue changes. 4) To assess the efficacy of prophylactic sucralfate in acute radiation proctitis a randomised study was initiated and carried out together with a meta-analysis of previously available data. 5) Most studies on clinical acute toxicity in pelvic RT use either the RTOG/EORTC score system or focus on diarrhoea/stool frequency. A more differentiated and sensitive recording was developed and tested to pick up symptoms escaping the commonly used scores. 6) Study the relation between histopathological findings and the clinical picture. 4 papers presenting various studies are included. The titles are: 1) Acute radiation proctitis: a sequential clinicopathologic study during pelvic radiotherapy. 2) Clinical significance of increased gelatinolytic activity in the rectal mucosa during external beam radiation therapy of prostate cancer. 3) Profiles and time course of acute radiation toxicity symptoms during conformal radiotherapy for cancer of the prostate. 4) Sucralfate does not ameliorate acute radiation proctitis. Some future prospects are discussed.

    To the best of our knowledge, histopathologic studies of syphilitic ears have generally focused on hydropic changes; so far, no such studies have investigated peripheral vestibular otopathology using differential interference contrast microscopy, in patients with syphilis. For this study, we examined 13 human temporal bone samples from 8 patients with a history of syphilis. Using conventional light microscopy, we performed qualitative histopathologic assessment. In addition, using differential interference contrast microscopy, we performed type I and type II vestibular hair cell counts on each vestibular sense organ with minimal autolysis; in which the neuroepithelium was oriented perpendicular to the plane of section. We then compared vestibular hair cell densities (cells per 0.01 mm² surface area) in the syphilis group vs. the control group. In the syphilis group, we observed precipitate in the endolymphatic or perilymphatic spaces in 1 (7.7 %) of the samples and endolymphatic hydrops in eight (61.5 %) of the samples. Hydrops involved the cochlea (four samples) and/or saccule (four samples). In addition, the syphilis group experienced a significant loss of type II vestibular hair cells in the maculae of the utricle and saccule, and in the cristae of the lateral and posterior semicircular canals, as compared with the control group (P < 0.05).

    With a continuous growing amount of annotated histopathological images, large-scale and data-driven methods potentially provide the promise of bridging the semantic gap between these images and their diagnoses. The purpose of this paper is to increase the scale at which automated systems can entail scalable analysis of histopathological images in massive databases. Specifically, we propose a principled framework to unify hashing-based image retrieval and supervised learning. Concretely, composite hashing is designed to simultaneously fuse and compress multiple high-dimensional image features into tens of binary hash bits, enabling scalable image retrieval with a very low computational cost. Upon a local data subset that retains the retrieved images, supervised learning methods are applied on-the-fly to model image structures for accurate classification. Our framework is validated thoroughly on 1120 lung microscopic tissue images by differentiating adenocarcinoma and squamous carcinoma. The average accuracy as 87.5% with only 17ms running time, which compares favorably with other commonly used methods.

    Colon cancer classification has a significant guidance value in clinical diagnoses and medical prognoses. The classification of colon cancers with high accuracy is the premise of efficient treatment. Our task is to build a system for colon cancer detection and classification based on slide histopathological images. Some former researches focus on single label classification. Through analyzing large amount of colon cancer images, we found that one image may contain cancer regions of multiple types. Therefore, we reformulated the task as multi-label problem. Four kinds of features (Color Histogram, Gray-Level Co-occurrence Matrix, Histogram of Oriented Gradients and Euler number) were introduced to compose our discriminative feature set, extracted from our dataset that includes six single categories and four multi-label categories. In order to evaluate the performance and make comparison with our multi-label model, three commonly used multi-classification methods were designed in our experiment including one-against-all SVM (OAA), one-against-one SVM (OAO) and multi-structure SVM. Four indicators (Precision, Recall, F-measure, and Accuracy) under 3-fold cross-validation were used to validate the performance of our approach. Experiment results show that the precision, recall and F-measure of multi-label method as 73.7%, 68.2%, and 70.8% with all features, which are higher than the other three classifiers. These results demonstrate the effectiveness and efficiency of our method on colon histopathological images analysis.

    Vascular leg ulcers remain a challenge for the modern health care, and a systematic pathological study on this kind of lesions has not been reported so far. A total of 293 consecutive white patients with chronic leg ulcers (present for a minimum of 6 months and up to several years) referred to the Wound Care Unit (Dermatology, University of Bologna) between March 2008 and June 2011. Thirty-four patients affected by other than vascular ulcers, neoplastic or inflammatory conditions, were excluded. The remaining 259 patients affected by vascular leg ulcers were enrolled in this study. Assessment of the patients general health, skin biopsy, and vascular Doppler of the lower limbs were performed to determine the etiology and to formulate an appropriate management plan, whereas 2 punch biopsies of 3 mm were performed on the border and on the bed of each ulcer. Doppler evaluation showed the presence of vascular hemodynamic impairment in 259 patients. Of these, 181 (69.9%) patients were affected by venous insufficiency, 58 (22.4%) by venous and arterial insufficiency, and 20 (7.7%) by arterial insufficiency. Histopathologic features revealed significant differences, thus, reflecting the clinicopathologic correlation with the underlying hemodynamic impairments. In conclusion, histopathologic and hemodynamic data correlation could provide the basis for future analysis of leg ulcers pathogenesis and may improve treatment protocols. We should underline that this observational study represents a single-institute experience and that larger series are needed to confirm our observations.

    Intraductal papillary mucinous neoplasms (IPMN) are pancreatic lesions with uncertain biologic behavior. This study sought objective, accurate prediction tools, through the use of quantitative histopathological signatures of nuclear images, for classifying lesions as chronic pancreatitis (CP), IPMN, or pancreatic carcinoma (PC). Forty-four pancreatic resection patients were retrospectively identified for this study (12 CP; 16 IPMN; 16 PC). Regularized multinomial regression quantitatively classified each specimen as CP, IPMN, or PC in an automated, blinded fashion. Classification certainty was determined by subtracting the smallest classification probability from the largest probability (of the three groups). The certainty function varied from 1.0 (perfectly classified) to 0.0 (random). From each lesion, 180 ± 22 nuclei were imaged. Overall classification accuracy was 89.6% with six unique nuclear features. No CP cases were misclassified, 1/16 IPMN cases were misclassified, and 4/16 PC cases were misclassified. Certainty function was 0.75 ± 0.16 for correctly classified lesions and 0.47 ± 0.10 for incorrectly classified lesions (P = 0.0005). Uncertainty was identified in four of the five misclassified lesions. Quantitative histopathology provides a robust, novel method to distinguish among CP, IPMN, and PC with a quantitative measure of uncertainty. This may be useful when there is uncertainty in diagnosis.

    Background Alopecia areata (AA) is a common disorder of unknown etiology that affects approximately 0.7% to 3.8% of patients among the general population. Currently, genetic and autoimmune factors are emphasized as etiopathogenic. Studies linking Human Leukocyte Antigens (HLA) to AA have suggested that immunogenetic factors may play a role in the disease's onset/development. Objectives To investigate an association between AA and HLA class I/II in white Brazilians. Methods: Patients and control groups comprised 33 and 112 individuals, respectively. DNA extraction was performed by column method with BioPur kit. Allele's classification was undertaken using the PCR-SSO technique. HLA frequencies were obtained through direct counting and subjected to comparison by means of the chi-square test. Results Most patients were aged over 16, with no familial history, and developed partial AA, with no recurrent episodes. Patients showed a higher frequency of HLA-B*40, HLA-B*45, HLA-B*53 and HLA-C*04 compared with controls, although P was not significant after Bonferroni correction. Regarding HLA class II, only HLA-DRB1*07 revealed statistical significance; nevertheless, it featured more prominently in controls than patients (P=0.04; Pc=0.52; OR=0.29; 95%; CI=0.07 to 1.25). P was not significant after Bonferroni correction. Conclusions The development of AA does not seem to be associated with HLA in white Brazilians, nor with susceptibility or resistance. The studies were carried out in populations with little or no miscegenation, unlike the Brazilian population in general, which could explain the inconsistency found. PMID:27438193

    目的 探讨男性型脱发的临床特征.方法 收集148例男性型脱发病例的临床资料,并对患者的发病年龄、家族史、临床分级、疗效、血清双氢睾酮(DHT)、轻拉试验进行分析.结果 发病年龄以 15~25岁占比例最大,家族史与发病年龄相关,家族史与临床分级相关,血清DHT水平升高占80.41%,非那雄胺治疗总有效率为88.98%,轻拉试验阳性占22.97%.结论 男性型脱发发病年龄偏早,发病与职业、精神神经因素有关,有家族史患者的发病年龄比无家族史患者的发病年龄更早,有家族史患者出现重型男性型脱发的可能性更大,疗效与疗程呈正相关,疗效与家族史无关,部分患者出现轻拉试验阳性.%Objective To investigate the clinical characteristics of androgenic alopecia. Methods The clinical information of 148 cases of androgenic alopecia during the last three years was collected. The age of onset, family history, clinical classification, therapeutic efficacy, plasma dihydrotestosterone ( DHT ), light hair - pull test of the patients were analyzed. Results Most diseases got onset at the age between 15 and 25. Significant correlations were revealed between the family history and onset age or clinical classification ( P <0. 05 ). Elevated DHT was also revealed in 80. 41% patients. The overall effective rate of fiansteride treatment and positive light hair-pull rates were 88. 98% and 22. 97% , respectively. Conclusion The onset age of androgenic alopecia is young. And it is correlated with occupational and psychiatric factors. Patients with family history suffer earlier onset age and higher probability of severe androgenic alopecia. However, the efficacy of treatment is correlated with the course of therapy but not with family history.

    Female genital ulcer is a disease that affects a large number of women, and its etiologic diagnosis can be difficult. The disease may increase the risk of acquiring HIV. Genital ulcer may be present in sexually transmitted diseases (STD)--syphilis, chancroid, genital herpes, donovanosis, lymphogranuloma venereum; and other non-STD disorders (NSTD)--Behçet's syndrome, pemphigus, Crohn's disease, erosive lichen planus and others. This study evaluated the clinical-histopathologic-microbiologic characteristics of female genital ulcers. A cross-sectional descriptive prospective study was conducted during a six-month period to investigate the first 53 women without a definitive diagnosis, seeking medical care for genital ulcers at a genital infections outpatient facility in a university hospital. A detailed and specific history was taken, followed by a dermatologic and gynecologic examination. In addition to collecting material from the lesions for microbiologic study, a biopsy of the ulcer was performed for histopathologic investigation. The average age of the patients was 32.7 years, 56.6% had junior high school education and higher education. The most frequent etiology was herpetic lesion, followed by auto-immune ulcers. At the time of their first consultation, around 60% of the women were using inadequate medication that was inconsistent with the final diagnosis. Histologic diagnosis was conclusive in only 26.4% of the patients (14/53). Cure was obtained in 99% of the cases after proper therapy. The female genital ulcers studied were equally distributed between sexually transmitted and non-sexually transmitted causes. Herpes was the most frequent type of genital ulcer, affecting women indiscriminately, mostly between the ages of 20 and 40 years. The etiologic diagnosis of herpetic ulcers is difficult to make even when various diagnostic methods are applied. It is imperative that NSTD should be included in the differential diagnoses of female genital ulcers. The

    2016-03-01

    Full Text Available Mycosis fungoides is the most common primary T-cell lymphoma of skin. The disease has a protean clinical and histological presentation in its early patch and plaque stages, when distinction from mimicking inflammatory dermatoses is difficult. Since no single criterion is specific enough, a reliable diagnosis in early stages requires integration of clinical, histopathological and molecular findings. In skin biopsies, the most helpful histologic features are the detection of atypical lymphocytes in the epidermis with minimal epidermal changes, basal alignment of lymphocytes along dermal-epidermal junction and formation of Pautrier microabscesses. An aberrant immunophenotype of T cells and molecular detection of a clonal T-cell population are factors that could allow a more specific diagnosis. This work recapitulates and discusses these features from a practical perspective.

    Full Text Available Biopsies from cutaneous and mucosal lesions from 40 patients with active paracoccidioidomycosis, were studied histopathologically. All cases exhibited chronic granulomatous inflammation and 38 also presented suppuration; this picture corresponded to the mixed mycotic granuloma (MMG. Pseudoepitheliomatous hyperplasia and the transepidermic (or epithelial elimination of the parasite, were observed in all cases. In paracoccidioidomycosis elimination takes place through formation of progressive edema, accompained by exocytosis. The edema gives rise to spongiosis, microvesicles and microabscesses which not only contain the fungus but also, various cellular elements. Cells in charge of the phagocytic process were essentialy Langhans giant cells; PMN's, epithelioid and foreign body giant cells were poor phagocytes. An additional finding was the presence of fibrosis in most biopsies.

    Full Text Available Autosomal recessive polycystic kidney disease (ARPKD is one of the most common inheritable disease manifesting in infancy and childhood with a frequency of 1:6,000 to 1:55,000 births. The patient in her second trimester presented with a history of amenorrhea. Ultrasound examination revealed bilateral, enlarged, hyperechogenic kidneys, placentomegaly, and severe oligohydramnios. The pregnancy was terminated. An autopsy was performed on the fetus. Both the kidneys were found to be enlarged and the cut surface showed numerous cysts. The liver sections showed changes due to fibrosis. The final diagnosis of autosomal recessive polycystic kidney disease was made based on these findings. In this article, we correlate the ante-natal ultrasound and histopathological findings in autosomal recessive polycystic kidney disease.

    2013-01-01

    Full Text Available Ameloblastic fibrodentinoma (AFD is considered a mixed odontogenic tumor that is characterized by conserved epithelial and ectomesenchymal neoplastic components. AFD is composed of long narrow cords and islands of odontogenic epithelium; the epithelial strands lie in a myxoid cell-rich ectomesenchymal tissue with stellate-shaped fibroblasts that exhibit long slender cytoplasmic extensions that resemble dental papilla. The lesions show the presence of dysplastic dentin. Although AFD is a rare entity and its very existence is not completely accepted, based on the extent of histodifferentiation, it is considered to represent a stage between ameloblastic fibroma and ameloblastic fibroodontoma. This study aimed to provide a histopathological and immunohistochemical characterization of this infrequent tumor. A large panel of antibodies including amelogenin, Ck 19, calretinin, syndecan-1, E-cadherin, MSH2, histone H3, and Ki-67 was used to illustrate the nature of the tumor.

    Virtual microscopy using digitized slides has become more widespread in teaching in recent years. There have been no direct comparisons of the use of virtual microscopy and the use of microscopes and glass slides. Third-year veterinary students from two different schools completed a simple objective test, covering aspects of histology and histopathology, before and after a practical class covering relevant material presented as either glass slides viewed with a microscope or as digital slides. There was an overall improvement in performance by students at both veterinary schools using both practical formats. Neither format was consistently better than the other, and neither school consistently outperformed the other. In a comparison of student appraisal of use of digital slides and microscopes, the digital technology was identified as having many advantages.

    The preparation, staining, visualization and interpretation of histological images of tissue is well accepted as the gold standard process for the diagnosis of disease. These methods have a long history of development, and are used ubiquitously in pathology, despite being highly time- and labour-intensive. Here, we introduce a unique optical imaging platform and methodology for label-free multimodal multiphoton microscopy that uses a novel photonic-crystal fibre source to generate tailored chemical contrast based on programmable supercontinuum pulses. We demonstrate the collection of optical signatures of the tumour microenvironment, including evidence of mesoscopic biological organization, tumour cell migration and (lymph-) angiogenesis collected directly from fresh ex vivo mammary tissue. Acquisition of these optical signatures and other cellular or extracellular features, which are largely absent from histologically processed and stained tissue, combined with an adaptable platform for optical alignment-free programmable-contrast imaging, offers the potential to translate stain-free molecular histopathology into routine clinical use.

    2015-01-01

    Full Text Available Sarcomatoid carcinomas are biphasic tumors proven to be monoclonal dedifferentiated forms of conventional squamous carcinomas. It is a variant of squamous cell carcinoma (SCC which has spindled tumor cells, which simulate a true sarcoma, but are epithelial in origin. They are extremely uncommon in the head and neck region. Only 10 cases have been discussed in the literature. When compared to SCC of maxilla, this variant is associated with poor diagnosis and advanced disease at presentation as is demonstrated in the case presented. Diagnosis of sarcomatoid squamous carcinoma is challenging because of overlapping histopathological features with other spindle-cell tumors. Understanding their clinicopathologic characteristics facilitates their diagnosis and appropriate clinical management. Surgery and radiotherapy form the mainstays of treatment. We report a rare case of spindle-cell carcinoma involving the mandible.

    Toxic industrial chemicals induce liver injury, which is difficult to diagnose without invasive procedures. Identifying indicators of end organ injury can complement exposure-based assays and improve predictive power. A multiplexed approach was used to experimentally evaluate a panel of 67 genes predicted to be associated with the fibrosis pathology by computationally mining DrugMatrix, a publicly available repository of gene microarray data. Five-day oral gavage studies in male Sprague Dawley rats dosed with varying concentrations of 3 fibrogenic compounds (allyl alcohol, carbon tetrachloride, and 4,4'-methylenedianiline) and 2 nonfibrogenic compounds (bromobenzene and dexamethasone) were conducted. Fibrosis was definitively diagnosed by histopathology. The 67-plex gene panel accurately diagnosed fibrosis in both microarray and multiplexed-gene expression assays. Necrosis and inflammatory infiltration were comorbid with fibrosis. ANOVA with contrasts identified that 51 of the 67 predicted genes were significantly associated with the fibrosis phenotype, with 24 of these specific to fibrosis alone. The protein product of the gene most strongly correlated with the fibrosis phenotype PCOLCE (Procollagen C-Endopeptidase Enhancer) was dose-dependently elevated in plasma from animals administered fibrogenic chemicals (P < .05). Semiquantitative global mass spectrometry analysis of the plasma identified an additional 5 protein products of the gene panel which increased after fibrogenic toxicant administration: fibronectin, ceruloplasmin, vitronectin, insulin-like growth factor binding protein, and α2-macroglobulin. These results support the data mining approach for identifying gene and/or protein panels for assessing liver injury and may suggest bridging biomarkers for molecular mediators linked to histopathology.

    Full Text Available Paratuberculosis (Johne’s diseases is responsible for massive economic losses to dairy industry, both in the industrially advanced as well as in the developing countries. To detect its occurrence in cattle and buffaloes locally, blood and tissue samples from clinically weak and grossly suspected slaughtered animals were collected from two abattoirs of Jhang, municipal area, Pakistan. Acid-fast smear staining, gross/histopathology and indirect ELISA were done for the detection of Mycobacterium avium subsp. paratuberculosis (MAP. Total 134 samples illustrating gross pathological lesions were collected, only 11.19% (cattle: 6.67%, buffaloes: 12.5% showed acid fast bacilli through smear staining and were taken as confirmed cases. Thickening of intestines alone was not a reliable indicator of Johne’s disease. Tissue sections from intestines and mesenteric lymph nodes from these acid fast positive animals were stained with hematoxylin & eosin (H&E and Ziehl Neelsen (ZN methods. Sum of (15/134 impression smear staining as well as (15/15 tissue sections of the intestines were found ZN positive, and only 6.7% of impression smears and 100% of tissue sections of mesenteric lymph nodes showed acid fast bacilli. Through ELISA, two cattle and five buffaloes (07/134 gave positive optical densities, while one cattle and seven buffaloes (08/134 were judged as doubtful. It is concluded that infection of MAP can be identified by histopathology and ELISA. The present study was the first record of paratuberculosis among the dairy animals slaughtered at Jhang abattoirs. The objective was to compare different methods for the diagnosis of Johne’s disease.

    Full Text Available In order to evaluate the reliability of histopathological classifications of cutaneous and mucocutaneous leishmaniasis the authors compared the histopathological patterns of two biopsies taken simultaneously from the same patient, and classified the material according to Ridley et al. (1980, to Magalhães et al. (1986a, and to a more simplified classification with only three patterns. District histopathological aspects, were observed in different lesions or even in the same lesion. The authors concluded that histopathological patterns do not represent a stage of tegumentary leishmaniasis, thus they can not be correlated with prognosis and therapeutical response as suggested in the literature.

    Fur condition in wild ringtailed lemurs, Lemur catta, was recorded during September-November birth seasons 2001-2006 at Berenty Reserve, Madagascar. Body coat condition was scored on a scale from BS 0: full, smooth coat with guard hairs, to BS5: half or more of back and limbs hairless. Tail condition was scored from TS 0: full, to TS 5: half or more hairless. Where troop core areas included stands of Leucaena leucocephala, alopecia was dramatically more frequent than in similar areas without leucaena, including many animals with score BS5 or TS5, "bald lemur syndrome." Females' coats were worse than males', possibly related to female dominance and access to this preferred food. Tails in non-leucaena-feeding females tend to remain full, even if coats deteriorate, but with leucaena-feeding female tails are highly correlated with coat condition and equally bare. Coat and tail condition in L. catta reflected not only the dietary toxin but individual differences as well as differences between adjacent troops that may result from territorially mediated access to the environment. Leucaena contains the non-protein amino acid mimosine, a known cause of alopecia, wasting, and organ damage in livestock, although the effects are usually reversible. This is the first case of its effect in wildlife. Leucaena is an agroforestry tree introduced throughout the tropics. In high dietary concentrations leucaena might potentially affect any browsing mammal.

    Full Text Available La artritis reumatoide es una enfermedad de tipo autoinmune. Por su carácter altamente invalidante, requiere de manejo farmacológico agresivo. Para ello, habitualmente se hace necesario el uso de drogas inmunomoduladoras agrupadas bajo el nombre de fármacos antirreumáticos modificadores de la enfermedad. Uno de los utilizados con mayor frecuencia es la leflunomida, la cual por su mecanismo de acción es capaz de suprimir ejes fundamentales en el proceso de la enfermedad. Sin embargo, su uso no se encuentra exento de efectos secundarios. Si bien existen series que reportan que los efectos adversos más prevalentes son diarrea, náuseas, exantema y alopecia, existen escasos reportes de casos de alopecia areata universal secundaria al uso de leflunomida. A propósito de un caso en el Hospital Regional de Talca, se realizó una revisión de la literatura acerca del tema.

    Diacylglycerol O-acyltransferase 1 (DGAT1) plays an important role in synthesizing lipids, and inhibitors of DGAT1 have been investigated as potential treatments for diabetes and metabolic diseases. DGAT1 knockout (-/-) mice are resistant to obesity, have increased sensitivity to insulin, and exhibit sebaceous gland atrophy and alopecia. Prolonged pharmacological inhibition of DGAT1 with AZD7687 in mice results in the same skin phenotype, including sebaceous gland atrophy and alopecia, as seen in the skin of DGAT1 (-/-) mice. AZD7687-mediated effects on the skin were dose- and time-dependent and reversible. They occurred only at substantial levels of continuous DGAT1 inhibition. Prolonged treatment of dogs with AZD7687 also resulted in sebaceous gland atrophy but did not result in the more adverse skin changes of hair loss and skin lesions. Our findings highlight a significant risk of generating the same lesions that were seen in mouse skin during clinical development of DGAT1 inhibitors in humans and also reveal a species difference in the effects on the skin, indicating that the mouse may be an especially sensitive species. Therefore, although human therapeutic doses may not have the same influence on skin morphology as seen in mice, monitoring of skin changes will be essential in clinical trials with DGAT1 inhibitors.

OBJECTIVE: To establish the age and sex distribution of children in the study population as well as the histopathological characteristics of gastrointestinal diseases that occurred in those children who were aged 14years and below in Sagamu, Southwestern Nigeria. MATERIALS AND METHODS: Demographic data such as age, sex, and clinical summary of children in the study population were extracted from the medical records of Olabisi Onabanjo University Teaching Hospital, Sagamu, Ogun State from January 2003 to December 2009. Based on this information, a review of paraffin embedded blocks and slides as well as histopathological reports of gastrointestinal diseases that occurred in those children aged 14years and below was undertaken at the Morbid Anatomy Department of the hospital. RESULTS: Seventy–four cases of gastrointestinal diseases were seen in children aged 14years and below. The majority (39.2% of gastrointestinal diseases were accounted for by appendiceal lesions. Hirschsprung’s disease, intussusceptions, enterocolitis and jejunal atresia accounted for 29.7%, 10.8%, 6.8% and 4.1% of cases respectively. Adenocarcinoma of the intestine was the predominant gastrointestinal tumour, occurring in 5 out of 7 children. Two cases of non-Hodgkin lymphoma were also seen. The ages of the children ranged from 2 to 14 years, with a mean age of 8.6years and a peak age incidence of gastrointestinal disease in the 10-14year age group. Male children were more commonly affected with the exception of appendiceal lesions, which occurred more in females (M:F ratio= 1.6:1.0. Acute suppurative appendicitis was the most prevalent lesion of the appendix, occurring in 13 out of 29 appendiceal lesions. Moderately differentiated to poorly

    Full Text Available Back ground: Xenoestrogens are compounds like estrogens in effect but not in structure which are mimicking the action of endogenous estrogen and activate estrogen receptor. Xenoestrogens are chemically distinct industrial products potentially able to disrupt the endocrine system by mimicking the action of endogenous steroid hormones. Among such compounds, the ubiquitous environmental contaminants bisphenol-A (BPA may promote adverse effects in humans triggering estrogenic signals in target tissues. Bisphenol- A is widely used in food and drinks packaging. Aim of the work: The present study is carrying out to evaluate the effect of bisphenol-A on sexual hormonal pattern in male albino rats. Material and Methods: 64adult male Sprague – Dawley rats (100-120 g were divided to four groups (16 rats/group.Group (1: control group without any treatment. Group(2: positive control group was injected subcutaneously (s.c with sesame oil daily. Group (3: received BPA daily with low dose (10 mg/kg/day s.c. Group (4: received BPA daily with high dose (30 mg/kg/day s.c. The experiment durated 30 days, half rats of each group were sacrificed after 15 days of treatment and the other half of groups after 30 days. The blood was collected, serum was separated and used for estimation of (hormonal levels, prolactin, gonadotrophin and testosterone and some biochemical parameters (liver enzymes, kidney function, protein and lipid profile. Testis, liver and kidney were taken for the histopathological examination.

    Molecular medicine is transforming modern clinical practice, from diagnostics to therapeutics. Discoveries in research are being incorporated into the clinical setting with increasing rapidity. This transformation is also deeply changing the way we practise pathology. The great advances in cell and molecular biology which have accelerated our understanding of the pathogenesis of solid tumours have been embraced with variable degrees of enthusiasm by diverse medical professional specialties. While histopathologists have not been prompt to adopt molecular diagnostics to date, the need to incorporate molecular pathology into the training of future histopathologists is imperative. Our goal is to create, within an existing 5-year histopathology training curriculum, the structure for formal substantial teaching of molecular diagnostics. This specialist training has two main goals: (1) to equip future practising histopathologists with basic knowledge of molecular diagnostics and (2) to create the option for those interested in a subspecialty experience in tissue molecular diagnostics to pursue this training. It is our belief that this training will help to maintain in future the role of the pathologist at the centre of patient care as the integrator of clinical, morphological and molecular information.

    2001-01-01

    Objective: To observe the ocular histopathological changes aftereyeball enucleation induced by corneal trauma.Methods: Light microscopic examination was done on 117 eyeball specimens enucleated after corneal trauma (18 with corneal fissure and 99 with corneal perforating trauma).Results: Acute, subacute or chronic inflammatory changes, and fibrous membrane formation were observed in well-closed corneal wounds, whereas inflammation, atrophy and scar were observed in the focal tissues. But at the late period, secondary glaucoma, retinal detachment, endophthalmitis and eyeball atrophy resulted in blindness. Corneal fistula was observed in those with inadequate cure of wounds caused by ingrowth of corneal epithelium, embedment of iris and vitreous body, and large area of centrally located tissue deficiency of the corneal. A high incidence of endophthalmitis was noted due to the presence of corneal fistula. Severe inflammation was observed in the anterior segmental tissues with fibrous infiltration in the anterior chamber, which might result in rapid destruction of the eyeballs.Conclusions: Ocular pathology varies with the difference of the position, form, size and closing conditions of the corneal laceration after trauma.

    Kalach 360 SL (KL) is a commercial herbicide which contains 360 g/l of glyphosate used in both agricultural and urban areas throughout the world including Tunisia. We aimed to evaluate the effects of KL on rats' renal system. Female Wistar rats were divided into three groups: group 1 (n = 6) received a standard diet and served as control, groups 2 and 3 (n = 12 each) received 0.07 ml (D1: 126 mg/kg), and 0.175 ml (D2: 315 mg/kg) of KL, respectively, for 60 d. The chronic exposure to KL induced a significant increase in plasma creatinine, urea, and uric acid levels. Creatinine clearance decreased in KL-treated groups, compared with controls. Several urine parameters, such as urine-specific gravity and urine osmolality, significantly decreased, while dieresis and urinary Na/K + ratio increased in KL-treated groups. These findings suggested a distal tubular damage caused by tubular necrosis. Moreover, the chronic exposure to KL induced an increase in lipid peroxidation (LPO) and a decrease in antioxidant status, enzymatic activities (superoxide dismutase and catalase) and non-enzymatic levels (vitamin C), which led to an oxidative stress. Histopathological studies showed a peritubular inflammatory reaction, nephrose, fragmented glomeruli, necrotic epithelial cells, and tubular dilatation. These results could have significant health implications for animal and human populations. Further data are necessary to investigate the potential consequences of chronic dose exposure during life.

    Full Text Available Ensemble learning is an effective machine learning approach to improve the prediction performance by fusing several single classifier models. In computer-aided diagnosis system (CAD, machine learning has become one of the dominant solutions for tissue images diagnosis and grading. One problem in a single classifier model for multi-components of the tissue images combination to construct dense feature vectors is the overfitting. In this paper, an ensemble learning for multi-component tissue images classification approach is proposed. The prostate cancer Hematoxylin and Eosin (H&E histopathology images from HUKM were used to test the proposed ensemble approach for diagnosing and Gleason grading. The experiments results of several prostate classification tasks, namely, benign vs. Grade 3, benign vs.Grade4, and Grade 3vs.Grade 4 show that the proposed ensemble significantly outperforms the previous typical CAD and the naïve approach that combines the texture features of all tissue component directly in dense feature vectors for a classifier.

    Purpose: To study the clinical manifestations and histopathologic changes of trabeculum after excimer laser trabeculectomy ab interno (ELT), and to investigate the mechanisms of ELT in reducing intraocular pressure. Methods : ELT was performed on ten rabbit eves and postoperative responses were documented. Comeoscleral tissue samples were harvested consecutively each week until the 5th postoperative week and these samples were examined under light and electrical microscopy. Results: Mild stimulation signs were present postoperatix'ely in nine of ten eyes, but no serious complications were experienced. Obvious inflammation was observed in one rabbit eye as a result of iris damage during the surgical manipulations. Local kactures on the trabecular meshwork and openings into Schlemm' s canal were detected in all tissue samples under light microscope. Mitochondria were found to be turgescent and dilated like vacuoles and endoplasmic reticula were found to be dilated under electrical microscope in the early postoperative period. Later, all trabecular cells returned normal and no fihroblast cells were ever detected. Conclusions: Permanent openings through trabecular meshwork into the inner wall of Schlemm's canal can be created with ELT. The outflow resistance of aqueous humor can be reduced with these openings and intraocular pressure can be controlled thereafter. Eye Science 2001; 17:11 ~ 15.

    Trichoepitheliomas are benign follicular appendage tumors with differentiation to all three segments of the hair follicle. A 2 years old female domestic short hair cat presented with a mass on the tail. The mass was surgically excised and for histopathologic and immunohistochemical studies, was sent to Department of Pathology. Histologically, the tumor was encapsulated and consisted of many islands of follicular epithelium and also cysts structures which varied in size and shape. The cells of epithelium islands were round to oval and had variable amounts of slightly, eosinophilic cytoplasm and euchromatic nuclei. The cystic structures were lined by a complex layer of squamous epithelium. Often, cells under went an abrupt transition between basal layers and keratinization without the development of a granular cell layer. No tendency of malignancy was seen in this case. According to mentioned characteristics, trichoepithelioma was diagnosed. By immunohistochemical study it was confirmed that this tumor had epithelial origin because squamous tumor cells reacted with the pan-cytokeratin antibody. The expression of β-catenin was predominately cytoplasmic and also together with numerous positive nuclei but membranous expression was inconsistenet. Distribution of neoplastic cells with β-catenin expression was more than 75% and labeling intensity was strong in both cytoplasm and nuclei. According to author's knowledge, this is the first report of trichoepithelioma in cat in Iran and also investigation of β-catenin expression in feline trichoepithelioma in veterinary literature.

    Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is a painful progressive condition of older horses that involves multiple teeth, including canines and incisors. EOTRH is uncommonly recognized by veterinary pathologists and in some cases may be misdiagnosed as cementoblastoma. The cause is unknown. The goals of this study were to describe the histopathologic features of EOTRH in 17 affected horses from the United States and to increase awareness of this condition. Samples ranged from affected tooth to the entire rostral mandible and maxilla. Affected teeth exhibited cemental hyperplasia and lysis. The marked proliferation of cementum in severe cases caused bulbous enlargement of the intra-alveolar portions of affected teeth. Several teeth contained necrotic debris, bacteria, and plant material in the regions of cemental lysis. All horses exhibited dentinal lysis in at least affected tooth, and several contained necrotic debris in these regions. Endodontic disease was often present with inflammation, lysis, necrotic debris, fibrosis, and/or a thin rim of atubular mineralized tissue in the pulp cavity. Periodontal disease was a common feature that was primarily characterized by moderate lymphoplasmacytic inflammation. Resorption with secondary hypercementosis appears to begin on the external surface of the teeth rather than within the pulp cavity. Distinguishing EOTRH from other diseases requires a complete history that includes the number and location of affected teeth, a gross description of regional hard/soft tissue health, and radiographic findings.

    Capillaria hepatica is a nematode parasite of wild rodents and other mammals. Adult worms inhabit the liver. Recently, during the necropsy examination of a group of 160 rabbits from a commercial supplier, firm pale or cystic areas (1-5 mm) were noted on the liver in thirteen animals. On further investigation, these animals were found to be infected with C. hepatica. The histopathological features of the infection in the rabbit are described for the first time and diagnostic features recorded. Lesions were identified predominantly in portal tracts consisting of dilated bile ducts with luminal debris, peribiliary inflammatory cell infiltrates, and fibrosis. Large granulomas (macrogranulomas) were evident in portal areas and involved the bile ducts. Macrogranulomas contained collections of characteristic C. hepatica eggs, macrophages, eosinophils, and lymphocytes. Small granulomas (microgranulomas), characterized by epithelioid macrophages surrounded by lymphocytes and eosinophils, were also identified. C. hepatica eggs were also observed in the lumina of the bile ducts and gall bladder. No adult C. hepatica worms were identified. Oocysts of Eimeria stiedae were also evident in the biliary epithelium in some animals. The unique characteristics of the C. hepatica life cycle are described, and the differential diagnosis of hepatic capillariasis is discussed.

    Full Text Available Abstract Background To review the clinical and pathological characteristics of median raphe cysts and to classify the lesions according to pathogenesis and histopathological findings. Methods The medical records of patients who were diagnosed with median raphe cysts between 2001 and 2010 were reviewed to document the clinical presentation and pathological findings of the cysts. Results Most patients were asymptomatic; however, 9 patients had inflammatory or infectious cysts that were tender or painful. Four patients who had cysts on the parameatus and distal prepuce had difficulty voiding. Hematuria and hematospermia were noted in 2 cases. Thirty-one cysts were lined with an urothelium-like epithelium, and a squamous epithelium lining was found in 3 cases. In 2 cases, a well-formed mucinous glandular structure was observed. The other 20 cysts consisted of mixed epithelia. After excision of the cysts under local or general anesthesia, an urethral fistula developed as a complication in only 1 case. Conclusions Median raphe cysts are benign lesions formed due to tissue trapping during the development of urethral folds. The cysts can be defined into 4 types based on pathological findings: urethral, epidermoid, glandular, and mixed. The associated symptoms and signs should be taken into consideration when determining the treatment for the cysts.

    Naturally occurring type 2 diabetes has been found in a colony of baboons. Ongoing characterization of the baboon colony maintained at the Southwest National Primate Research Center has revealed a significant range of glucose sensitivity with some animals clearly diabetic.   Seven baboons, four with diabetes and three without diabetes, underwent histopathological investigation. Three diabetic animals were diagnosed using fasting blood glucose, hemoglobin A1C, and intravenous glucose tolerance test, and a fourth one was known to have hyperglycemia. One control baboon and three baboons with diabetes had microalbuminuria. On kidney biopsy, diabetic baboons had thickening of the glomerular basement membrane and mesangial matrix expansion compared to controls. Immunohistochemistry showed the diabetic animals had increased mesangial expression of cellular fibronectin ED-A. Two diabetic animals with microalbuminuria had evidence of mesangiolysis with the formation of an early nodule. One diabetic animal had a Kimmestiel-Wilson nodule. We conclude that the baboon represents a useful primate model of diabetes and nephropathy that resembles the nephropathy associated with type 2 diabetes in humans.

    This study is to find out the histopathological characteristics of lymph node sinus containing blood. Routine autopsy was carried out in the randomly selected 102 patients(among them,100 patients died of various diseases, and 2 of non-diseased causes),their superficial lymph nodes locating in the bilateral neck, axilla, inguina, thorax and abdomen were sampled. Haematoxylin-eosin staining was performed on 10% formalin-fixed and paraffin-embedded lymph node tissue sections(5μm).The histological characteristics of the lymph node sinuses containing blood were observed under light microscope. Among the 1362 lymph nodes sampled from the 100 autopsies, lymph sinuses containing blood were found in 809 lymph nodes sampled from 91 cases, but couldn't be seen in the lymph nodes sampled from the non-diseased cases. According to histology, five kinds of lymph sinuses containing blood were found:vascular-opening sinus, blood-deficient sinus, erythrophago-sinus, blood-abundant sinus, and vascular-formative sinus. It is concluded that in the state of disease, the phenomenon of blood in the lymph sinus is not uncommon. Blood could possibly enter into lymph sinus through lymphatic-venous communications between the veins and sinuses in the node. Lymph circulation and blood circulation could communicate with each other in the lymph sinus.

    This report describes a suicide case by acute arsenic intoxication via intravenous injection. A 30-year-old woman injected arsenic As (V) (sodium arseniate disodique: Disodium Hydrogena Arsenik RP) in a successful suicide attempt. Three hours following administration, the woman developed severe digestive symptoms. She was admitted to a hospital and transferred to the intensive care unit within 12 h of the massive administration of arsenic. Despite therapeutic efforts, over the next 2 h she developed multiorgan failure and died. A postmortem examination was performed. Pulmonary edema and congestion of liver were apparent. As (V) and As (III) were determined by high performance liquid chromatography and inductively coupled plasma mass spectrometry after mineralization of samples by concentrated nitric acid. Toxicological analysis revealed high concentrations of arsenic in biological fluids as well as in organs. Histopathological examination showed a typical indication of myocarditis. These findings were in agreement with acute arsenic poisoning. The symptoms developed by this young woman (intoxication by intravenous administration) were comparable to oral intoxication. The clinical signs, survival time, and administration type are discussed in light of the literature on acute and chronic arsenic poisoning.

    Condylar hyperplasia is a rare disorder characterized by an increased volume of the condyle, ramus, and mandibular body leading to facial asymmetry. We present three cases of condylar hyperplasia: two women and one man, age range 27 to 34. Clinically, all three patients showed a deviation of the mandible to the opposite side and a protruded position of the chin, hypertrophy of the lower border of the mandible, combined with an elongation of the mandibular ramus, open-bite on the deformed side, and cross-bite on the opposite side. In all three cases, scintigraphy showed an increased uptake. Radiography and CT scanning confirmed the clinical diagnosis and patients were subjected to surgery, comprising high condylectomy on the affected side with access in the pre-tragus area. The surgical piece sent to the Institute of Pathological Anatomy for histological examination revealed a nonuniform picture, in terms of both the depth of cartilage islands and the thickness of the fibrous layer covering the joint surface. Common to all three cases, however, was the apparent evolution of fibrous tissue to cartilage, and of this to compact bone tissue. At two-four years, all cases have maintained a good occlusal response. The asymmetric deformity of the mandible resulting from the rare condition of hemimandibular hyperplasia is presented and the clinical, histopathological and therapeutic aspects discussed.

    Sheep with Johne's disease develop epithelioid macrophage microgranulomas, specific to Mycobacterium avium subsp. paratuberculosis (Map) infection, in the terminal ileum, mesenteric lymph nodes, and organs distant to the alimentary tract such as the liver. The objectives of this study were to determine whether liver pathology was present in ewes affected by Map and whether liver cores provide adequate tissue for this potential diagnostic marker. One hundred and twenty-six adult, low body condition ewes were euthanized, necropsied, and underwent simulated liver biopsy. Ileal lesions typical of Map were found in 60 ewes. Hepatic epithelioid microgranulomas were observed in all ewes with Type 3b (n = 40) and 82% (n = 11) with Type 3c ileal lesions. None were found in ewes unaffected by Map or with Type 1, 2, or 3a ileal lesions. Liver biopsy core samples provided adequate tissue for histopathology with a sensitivity and specificity of 96% (95% confidence interval [CI], 0.87-0.99) and 100% (95% CI, 0.95-1), respectively for detection of types 3b and 3c ileal lesions.

    BACKGROUND American tegumentary leishmaniasis has an annual incidence of 1 to 1.5 million cases. In some cases, the patient's immune response can eliminate the parasite, and the lesion spontaneously resolves. However, when this does not occur, patients develop the disseminated form of the disease. OBJECTIVE To investigate the association between clinical, laboratory and pathological findings in cases of American tegumentary leishmaniasis. METHODS A retrospective study of the medical records of 47 patients with American cutaneous leishmaniasis. Clinical, laboratory and epidemiological data were collected, and semi-quantitative histopathological analyses were performed using the Spearman correlation coefficient (p Montenegro reaction, degree of granulomatous transformation and epithelioid cell count; duration of disease, Montenegro reaction and number of lymphocytes; epithelial hyperplasia and edema, hemorrhaging, and epithelial aggression; number of plasmocytes and number of parasites. The main negative correlations found were as follows: age and serology; time and parasite load; epithelial hyperplasia and degree of granulomatous transformation. CONCLUSION The long duration of the disease could be explained by the fact that lesions were relatively asymptomatic, and therefore ignored by patients with low literacy levels. Individuals may have simply waited for spontaneous healing, which proved to be dependent on the activation of hypersensitivity mechanisms. PMID:24626648

    Lichen sclerosus et atrophicus and limited systemic scleroderma (acrosclerosis) are inflammatory skin diseases that ultimately evolve into two distinct modes of atrophic scar formation, but which can easily be confused clinically. They are very rarely associated. The literature has reported cases in which lichen sclerosus was associated with various forms of scleroderma, but often with localized morphea. The characteristic histopathological picture of lichen sclerosus includes a thin epidermis, with orthohyperkeratosis and vascular degeneration in the basal layer, loss of elastic fibers, and band-like inflammatory infiltrate in the papillary dermis, while systemic sclerosis is characterized by excessive deposition of collagen in the dermis, accompanied by reduction in adnexal structures and their entrapment in collagen, and the presence of perivascular lymphocytic inflammatory infiltrate. We present the case of a 40-year-old female patient clinically diagnosed with systemic scleroderma and lichen sclerosus involving the genital mucosa. Physical examination in conjunction with laboratory findings (elevated antinuclear, anti-Scl-70, anti-SSA antibodies and immunogram) induced the supposition of the coexistence of lichen sclerosus and systemic scleroderma, fact confirmed by pathological examination. Systemic therapy with corticosteroids, immunosuppressive and phlebotropic drugs, peripheral vasodilators and other tropic adjuvants and topically potent topical corticosteroids was initiated. The course was favorable under therapy, the hardened skin slightly regaining elasticity, relief of itching and disappearance of lichen sclerosus lesions. Our case reaffirms the uncommon association of these two disorders. The importance of history, physical and laboratory examinations in making a diagnosis of certainty in emphasized.

    Results: The mean age of the patients was 50.48+/-7.50 (min:38, max:74. Leiomyoma with 77 case (%45.3 was the most hysterectomy indicated disease. Thereafter, dysfunctional uterine bleeding in 50 (%29.49, and endometrial hyperplasia 22 (%12.9 were detected. The other clinical indications were uterine prolapse in 17 patients (%10, chronic pelvic pain in 2 (%1.2 and adenomyosis in 2 (%1.2. The results of histopathological reports belong to hysterectomy materials indicated that leiomyoma was the most common pathological finding with 87 cases (%51.2, subsequently adenomyosis in 35 cases (% 20.5 and endometrial hyperplasia in 31 (18.3 was detected. Endometrial polyp was found in 10 cases (%5.9 and atrophic endometrium in 7 cases (%4.1. Combined pathology was defined in 44 hysteterctomy materials. Leiomyoma and endometrial hyperplasia were detected as the most common combination with a ratio of %50. In addition, chronic cervicitis was seen in %64.7 of cervical examinations of hysterectomy materials. Conclusion: Adenomyosis should be kept in mind while planning the diagnosis and treatment of patients whose admitted with compliants of menometrorrhagia, seconder dysmenorrhea and chronic pelvic pain in 4th and 5th decade. Endometrial sampling caused by the co-existence of leiomyoma and endometrial hyperplasia must be necessary in hysterectomy planned cases for leiomyoma those already have menometrorrhagia.

    Full Text Available BACKGROUND Endometriosis is a common benign gynaecological disorder. The true prevalence is difficult to quantify as women with disease are often asymptomatic and imaging modalities have low sensitivities for diagnosis. The primary method of diagnosis is Laparoscopy with or without biopsy for histologic diagnosis. Strict histologic criteria will confirm the surgical diagnosis in approximately 50-65% of cases. DESIGN, SETTING AND METHODS This is a prospective observational institution based study. A total of 50 patients undergoing laparoscopy were included in the study in accordance with the inclusion and exclusion criteria. The results were tabulated for comparison and standard statistical software were used for data presentation. RESULTS In this study, we observed that laparoscopy although adequately sensitive to diagnose endometriosis lacks the specificity except in the case of ovarian endometriosis. So laparoscopy without histological confirmation may give rise to false positive results, which may lead to overtreatment of patients. Due to the high negative predictive value of laparoscopy, absence of lesion anywhere on laparoscopy can virtually exclude the diagnosis of endometriosis, saving both time and expertise. CONCLUSION We conclude that laparoscopy should always be combined with histopathology for accurate diagnosis in presence of any suggestive or doubtful lesion, but is not mandatory in absence of lesion anywhere in the pelvis. The laparoscopic staging of endometriosis has a positive correlation with histologic diagnosis of endometriosis.

    Eosinophils, a constitutive component of the columnar-lined gastrointestinal tract, play an essential role in allergic responses and parasitic infections. The tissue density of these cells also increases in a variety of conditions of uncertain etiology. With the exception of the esophageal squamous epithelium, in which no eosinophils are normally present, the population of normal eosinophils in the remainder of the luminal gut is poorly defined. Therefore, histopathologists must rely on their subjective judgment to determine when a diagnosis of eosinophilic gastritis, enteritis, or colitis should be rendered. Eosinophilic esophagitis is currently the best defined and most studied eosinophilic condition of the digestive tract; therefore, the confidence in accurate diagnosis is increasing. In contrast, the characteristic clinicopathologic features of eosinophilic conditions affecting other parts of the digestive tract remain somewhat elusive. This review was designed to present pathologists with simple and practical information for the biopsy-based histopathologic diagnosis of eosinophilic esophagitis, gastritis, enteritis, and colitis. It was prepared by critically reviewing more than 200 articles on the topic, along with incorporating evidence accumulated through our own collective experience. We anticipate that by increasing pathologists' confidence in reporting these abnormal but often nameless eosinophilic infiltrates, we can help better define and characterize their significance.

  20. Changing Histopathological Diagnostics by Genome-Based Tumor Classification

    Full Text Available Traditionally, tumors are classified by histopathological criteria, i.e., based on their specific morphological appearances. Consequently, current therapeutic decisions in oncology are strongly influenced by histology rather than underlying molecular or genomic aberrations. The increase of information on molecular changes however, enabled by the Human Genome Project and the International Cancer Genome Consortium as well as the manifold advances in molecular biology and high-throughput sequencing techniques, inaugurated the integration of genomic information into disease classification. Furthermore, in some cases it became evident that former classifications needed major revision and adaption. Such adaptations are often required by understanding the pathogenesis of a disease from a specific molecular alteration, using this molecular driver for targeted and highly effective therapies. Altogether, reclassifications should lead to higher information content of the underlying diagnoses, reflecting their molecular pathogenesis and resulting in optimized and individual therapeutic decisions. The objective of this article is to summarize some particularly important examples of genome-based classification approaches and associated therapeutic concepts. In addition to reviewing disease specific markers, we focus on potentially therapeutic or predictive markers and the relevance of molecular diagnostics in disease monitoring.

    Full Text Available In this retrospective study, we reviewed the medical records, and histopathology findings of 191 patients who underwent renal biopsies at King Hussein Medical Center (KHMC during a four-year period (1993-97. All were performed using Tru-Cut needles under ultrasound guidance. There were 119 males (62.3% and 72 females (37.7%; the mean age was 29.1 years (range 5-76 years. Side effects of the renal biopsies included pain at the site of he biopsy in 17 (8.9%, gross hematuria in six (3.1% and hematuria requiring blood transfusion in one (0.5% patient. Nephrotic syndrome was the most common indication for biopsy followed by acute renal failure of unknown etiology. Among the nephritic patients, minimal change disease and post-infectious glomerulonephritis (GN were the commonest findings in children below the age of 15 years, membrano-proliferative GN ranked first in adults whole membranous GN and amyloidosis were more common in the elderly. WE conclude that renal biopsy was associated with a n acceptably low rate of complications in our practice, and that the patterns of renal histology vary slightly from those reported from other countries.

    Five years' experience of operating a Regional Lymphoma Histopathology Panel is described. During this period, approximately 1400 cases were registered of which nearly 1200 were confirmed as malignant lymphoma. Complete concordance of diagnosis was achieved between submitting pathologists and the Panel in two-thirds of cases of Hodgkin's disease and just over half of non-Hodgkin's lymphoma. Most discrepancies in diagnosis were found to be of clinical importance in terms of prognosis and/or therapeutic management of patients. In approximately two-thirds of such instances disagreement arose because of wrong assignment of tumour grade within the main lymphoma class but in one-third of cases the main class of lymphoma was wrongly designated. Panel members experienced similar diagnostic problems as submitting pathologists although to a lesser extent. The existence of the panel has not reduced the proportion of cases causing diagnostic difficulty for submitting pathologists or panel members during the 5 year study period. The principal cause of death was ascertained from death certificates and autopsy findings in nearly half the cases dying during the study period. In approximately half of these infection (largely pulmonary) played a major role while most of the remainder died of various cardiovascular, pulmonary or renal disorders. There was no specific pattern relating to the main lymphoma class. It is concluded that whilst the panel fulfils a useful function in resolving diagnostic difficulties and standardizing lymphoma diagnosis its role is restricted somewhat by the limitations imposed by conventional morphological assessments.

    In order to obtain a reliable experimental model simulating human esophageal cancer, endoscopic and histopathological studies were undertaken in the esophageal cancer produced in the beagle dog. Thirty-seven dogs had been given a solution of N-Ethyl-N'-nitro-N-nitrosoguanidine (ENNG) at a concentration of 150 micrograms/ml for 3-9 months. Follow-up studies included serial endoscopy and biopsy, and almost all animals were eventually sacrificed for histological examination. The results were as follows: Squamous cell carcinoma was observed in 5 out of 22 female dogs, while none in male dogs at all. For the induction of squamous cell carcinoma in the esophagus, administration in the condition of 150 micrograms/ml (75mg/day) for 6-9 months was most suitable. Almost all of esophageal lesions were protruding and well-differentiated squamous cell carcinoma with invasion of the submucosa. The stages of hyperplasia, dysplasia and squamous cell carcinoma in the esophagus were chronologically followed. Carcinoma had been observed in the stomach about 4 months prior to the appearance of esophageal carcinoma. This experimental model was proved to be useful for studies on histogenesis of human esophageal cancer both light and electron microscopically.

    Periodontal disease is one of the most frequent diseases affecting people all over the world. The relation between periodontal disease and diabetes mellitus raised the interest both of dentists and doctors treating metabolic diseases, as the two conditions influence one another. In our study, we analyzed a number of 75 patients with diabetes mellitus and periodontal disease that presented to the medical consultory for conditions of the dental maxillary system. The clinical study showed that periodontal disease and diabetes may affect young adults as well, still this pathological association more frequently appears after the age of 50. The disease was identified especially in the women living in urban area. The clinical examination of the dental maxillary system identified the presence of gingival ulcerations, dental calculus, gingival bleeding, radicular leftovers with anfractuous margins, fixed prostheses with an inappropriate cervical adjustment. Of the systemic diseases associated to periodontal disease and diabetes mellitus, there was observed that 66.66% of the patients also suffered from cardiovascular diseases (high blood pressure, ischemic cardiopathy, heart failure), and 37.33% suffered from obesity. The histopathological and immunohistochemical tests highlighted the presence of an inflammatory chronic, intense reaction, mainly formed of lymphocytes, plasmocytes, macrophages and granulocytes, heterogeneously disseminated and alteration of the structure of marginal and superficial periodontium. The inflammatory reaction in the patients with periodontal disease and diabetes was more intense than in the patients with periodontal disease without diabetes.

    Sarcoidosis is a chronic multisystemic granulomatous disease of unknown etiology, characterized by the formation of noncaseating granulomas in the involved organs. Cutaneous involvement is about 25% with different clinical expressions, the lichenoid pattern being one of the rarest types of cutaneous sarcoidosis. Lichenoid sarcoidosis clinically manifests with multiple scale papules involving extensive skin areas, especially the trunk, limbs, and face mimicking a lichen planus. Although diverse histologic patterns have been previously related, a lichenoid granulomatous infiltrate involving the dermo-epidermal junction has never been reported in lichenoid sarcoidosis. We report a case of a 43-year-old woman presenting with skin-colored pruritic papules, slightly scaling in trunk, extremities, and ears. These symptoms condition continued to expand and worsen for several years. The patient was otherwise in good health with no lymphadenopathies. Histopathologic examination of a skin biopsy showed an upper dermal granulomatous infiltrate of epithelioid cells, without necrosis, distributed in a lichenoid pattern with many cytoid bodies. We consider this may be the first case presenting a characteristic microscopic granulomatous lichen-like pattern in the setting of a clinically lichenoid type of sarcoidosis.

    ABSTRACT Background: Morbid obesity is a multifactorial disease that increasingly is being treated by surgery. Aim: To evaluate gastric histopathological changes in obese, and to compare with patients who underwent gastrojejunal bypass and the jejunal mucosa after the surgery. Methods: This is an observational study performed at a tertiary public hospital, evaluating endoscopic biopsies from 36 preoperative patients and 35 postoperative. Results: In the preoperative group, 80.6% had chronic gastritis, which was active in 38.9% (77.1% and 20.1%, respectively, in the postoperative). The postoperative group had a significant reduction in H. pylori infection (p=0.0001). A longer length of the gastric stump and a time since surgery of more than two years were associated with Helicobacter pylori infection. The jejunal mucosa was normal in 91.4% and showed slight nonspecific chronic inflammation in 8.6%. Conclusion: There was a reduction in the incidence of Helicobacter pylori infection in the postoperative group. A longer length of the gastric stump and longer time elapsed since surgery were associated with Helicobacter pylori infection. The jejunal mucosa was considered normal in an absolute majority of patients. PMID:27683773

    Objective: To study the relationship between histopathology and clinical prognosis of invasive pituitary adenoma subjected to transsphenoidal surgery. Methods: The enrolled were 82 patients with invasive pituitary adenomas undergoing transsphenoidal surgery during Jan. 2000 May 2003 in our department with full MR imaging findings, pathology data and follow-up information. The follow-up duration was 5-30 months. Results: MR imaging findings of invasive pituitary adenoma included: depression of the sellar floor, involvement of sphenoid sinus and cavernous sinus, breakthrough of diaphragma sellae,encasement of internal carotid artery, etc. Pathological examination revealed that the invasion rate of dura in sella turcica was the highest among the structures around tumor. Pituitary adenoma apoplexy was found in 20 cases (24.4%). The total removal rate for PRL-secreting adenomas was significantly lower than that for non-secreting adenomas (P<0.01), but non-, GH-, ACTH-secreting adenomas had no significant differences. The recurrence rate of PRL-secreting adenornas was higher than that of non- and GH-secreting adenomas (P<0.05). Conclusion: Among invasive pituitary adenomas, the therapeutic effects of nonand GH-secreting pituitary adenomas are better than that of PRL-secreting adenomas. Invasive biological behaviors of invasive pituitary adenomas result in radical operation failure and postoperative recurrence.

    Full Text Available Objective: to describe a case of the total development of alopecia in a female patient with psoriatic arthritis during treatment with a tumor necrosis factor-αlpha (TNF-α inhibitor. Materials and methods. Patient I., aged 36 years has been followed up at the Kazan’ Center of Rheumatic Diseases and Osteoporosis since 1998. At approximately the same time, the patient noted the appearance of skin eruptions behind the ears, on the skin of the scalp. She was examined by a dermatologist who diagnosed psoriasis. In 2005, she was admitted to Kazan’ Rheumatology Center, City Clinical Hospital Seven, for the development of obvious synovitis of the knee joint and for the inefficiency of therapy with nonsteroidal anti-inflammatory drugs and diagnosed with psoriatic arthritis. During the prescribed therapy with methotrexate 10 mg/week, evident menstrual irregularities were observed in the patient who stopped using the drug herself. The second pregnancy occurred in 2008. Articular syndrome progression and eruptive psoriasis were recorded in the lactation period. After lactation cessation in 2009, she was hospitalized again. Her examination revealed high laboratory activity (erythrocyte sedimentation rate, as high as 40 mm/hr; magnetic resonance imaging of the knee joints showed the signs of bilateral synovitis; lumbar spine radiography exhibited grade II sacroiliitis. Leflunomide 20 mg/day was recommended as a basic drug. In 2012, the patient used leflunomide, her condition worsened; joint pain progressed; new joints were involved into the process, and cutaneous manifestations were aggravated. To verify a diagnosis and to choose therapy, the patient was referred to a consultation at the Moscow Research Institute of Rheumatology. Results. In connection with the high activity of the disease and with no response to the performed therapy, it was recommended to initiate therapy with biologics, such as infliximab, the drug of choice.

    Full Text Available Statement of Problem: Many authors have claimed that pulpal inflammation may occur following periodontal diseases. Appropriate diagnosis of different lesions that have affected the dental pulp or periodontium is critical for prevention of unnecessary or harmful treatments; this must be taken into account before treatment.Purpose: The purpose of this study was histological evaluation of the pulp in the teeth with advanced periodontitis.Materials and Method: 30 permanent single teeth root that had advanced periodontitis with attachment loss ≥ 5 mm at least in one surface were used. The teeth were not maintainable and did not have caries, restoration and any sign of primary trauma from occlusion and did not receive any periodontal professional treatment in the past 6 months with no background of trauma. After clinical and radiographical examination and confirmation of the existence of advanced periodontitis, the teeth were extracted. Then cracks were created in the teeth by special clips. After fixation of the teeth in 10% formalin solution and decalcification by 10% nitric acid, the sections were prepared and stained by hematoxylin and eosin and then evaluated from histological perspectives. The data were analyzed by Spearman correlation coefficient ANOVA, t-test and Kruskal wallis tests.Results: In this survey, we did not find any significant correlation between clinical findings and histopathological situation. The relationship between clinical attachment loss and pulp diagnosis was statistically significant ( p =0.043. Also there was a statistically significant relationship between clinical attachment loss and calcification in the pulp ( p =0.014.Conclusion: According to the result of this research, it seems that periodontal condition affects the pulpal condition and it should be considered in future treatments on these teeth.

    AIM: To describe the imaging features of hepatic mesenchymal hamartoma with emphasis on magnetic resonance imaging (MRI) compared to histopathologic results.METHODS: Spin-echo sequence(SE),fast spin-echo sequence(FSE) were detected in 12 children (7 males, 5 females) with mesenchymal hamartoma of the liver (MHL), aged 1.2 months to 12 years,( mean age, 6.3 years) by axial, saggital, coronary plain imaging with an Elscint 2.0T MR equipment. Their main symptoms were abdominal mass (5 cases), enlarged liver (8 cases), abdominal pain (1 case) and anemia (2 cases),and negative alpha-fetoprotein. Dynamic enhancement examination was added in 2 cases.RESULTS: Six cases had single mass type of MHL, in which 3 cases had solid masses showing slight low-signal-intensity in T1WI, and irregular high-signal-intensity in T2WI, 1 case had a cystic-solid mixed mass showing several border-clear cysts in a solid mass, 2 cases had cystic masses with multi-septa. Five cases had diffuse and multifocal lesions type of MHL with its signal intensity being similar to that of the solid mass. One case had a combined diffuse and single cystic mass. In the early dynamic enhancement examination, the lesions were slightly circum-enhanced, and the center was enhanced in the later scan images. Inner hepatic vessels were compressed in 5 cases, vena cava and abdominal aortae were compressed in 3 cases. Pathological findings included fiber hyperplasia, hyaline degeneration, biliary duct hyperplasia, lobule-like array.CONCLUSION: MR imaging is a better way to differentiate and diagnose MHL. MHL may be recognized by its characteristic occurrence in infancy and MR imaging features.

    Full Text Available Abstract Background Robust hardware and software tools have been developed in digital microscopy during the past years for pathologists. Reports have been advocated the reliability of digital slides in routine diagnostics. We have designed a retrospective, comparative study to evaluate the scanning properties and digital slide based diagnostic accuracy. Methods 8 pathologists reevaluated 306 randomly selected cases from our archives. The slides were scanned with a 20× Plan-Apochromat objective, using a 3-chip Hitachi camera, resulting 0.465 μm/pixel resolution. Slide management was supported with dedicated Data Base and Viewer software tools. Pathologists used their office PCs for evaluation and reached the digital slides via intranet connection. The diagnostic coherency and uncertainty related to digital slides and scanning quality were analyzed. Results Good to excellent image quality of slides was recorded in 96%. In half of the critical 61 digital slides, poor image quality was related to section folds or floatings. In 88.2% of the studied cases the digital diagnoses were in full agreement with the consensus. Out of the overall 36 incoherent cases, 7 (2.3% were graded relevant without any recorded uncertainty by the pathologist. Excluding the non-field specific cases from each pathologist's record this ratio was 1.76% of all cases. Conclusions Our results revealed that: 1 digital slide based histopathological diagnoses can be highly coherent with those using optical microscopy; 2 the competency of pathologists is a factor more important than the quality of digital slide; 3 poor digital slide quality do not endanger patient safety as these errors are recognizable by the pathologist and further actions for correction could be taken.

    Full Text Available Background: Celiac disease (CD is an immune-mediated enteropathy triggered by the ingestion of gluten in genetically susceptible subjects. Although the small intestinal mucosa is the main site of the gut's involvement in CD, other mucosal surfaces belonging to the gastrointestinal tract and the gut-associated lymphoid tissue are known to be affected. Aim: Assuming that the oral mucosa could reflect the histopathological inflammatory alterations of the intestine in CD patients, this study wishes to assess the pattern of T-cell subsets in the oral mucosa of young adults with CD. Methods: A group of 37 patients (age range 20-38 years; female: male ratio 28:9 with CD were enrolled. Out of 37 patients, 19 patients (group A followed a gluten free diet (GFD -2 patients from less than one year; 6 patients between 1 and 5 years; 11 patients more than 5 years- while 18 patients (group B were still untreated. Fifteen healthy volunteers (age range 18-35 years, female: Male ratio 11:4 served as controls for the CD patients. Ethical approval for the research was granted by the Ethics Committee. Biopsy specimens were taken from normal looking oral mucosa. The immunohistochemical investigation was performed with monoclonal antibodies to CD3, CD4, CD8, and γδ-chains T cell receptor (TCR. Results: The T-lymphocytic inflammatory infiltrate was significantly (p < 0.0001 increased in group B (both compared with group A and with the control group. Conclusion: This study confirms the oral cavity to be a site of involvement of CD and its possible diagnostic potentiality in this disease.

    The purpose of this paper was to evaluate the relationship between the thrombosis and secretory duct dilation, lesion size, clinical types, nature (primary or recurrent) and duration of illness in the development of ranula. A total of 229 cases of sublingual gland cysts were treated with surgical resection from Jan. 1990 to Feb. 2010. The patients' data were investigated on histopathological findings, size of ranula, the clinical types, nature of ranula (primary or recurrent) and duration of illness. Sections from the paraffin-embedded blocks were HE-stained. CK expression was immunohistochemically detected. Among 229 cases the incidence of venous thrombosis was 58.52%. The incidence of venous thrombosis with or without duct dilation was 73.25% and 26.39% respectively, with a significant difference between the two groups (Pranulas with diameter larger or less than 3 cm was 72.22% and 46.28% (Pranula, plunging ranula and mixed ranula was 49.37%, 77.19% and 85.71% respectively, with a significant difference found between oral and plunging or mixed ranula (Pranula patients with duration of illness longer or less than 3 months was 69.77% and 51.75% (Pranulas was 51.85% and 64.85%, without a significant difference noted between them (P>0.05). It is concluded that the formation of venous thrombosis was related to the dilation of secretory duct, lesion size, clinical types, duration of lesion but formation of venous thrombosis was not related to the nature (primary or recurrent) of ranulas.

    White-nose syndrome (WNS) is a cutaneous fungal disease of hibernating bats associated with a novel Geomyces sp. fungus. Currently, confirmation of WNS requires histopathologic examination. Invasion of living tissue distinguishes this fungal infection from those caused by conventional transmissible dermatophytes. Although fungal hyphae penetrate the connective tissue of glabrous skin and muzzle, there is typically no cellular inflammatory response in hibernating bats. Preferred tissue samples to diagnose this fungal infection are rostral muzzle with nose and wing membrane fixed in 10% neutral buffered formalin. To optimize detection, the muzzle is trimmed longitudinally, the wing membrane is rolled, and multiple cross-sections are embedded to increase the surface area examined. Periodic acid-Schiff stain is essential to discriminate the nonpigmented fungal hyphae and conidia. Fungal hyphae form cup-like epidermal erosions and ulcers in the wing membrane and pinna with involvement of underlying connective tissue. In addition, fungal hyphae are present in hair follicles and in sebaceous and apocrine glands of the muzzle with invasion of tissue surrounding adnexa. Fungal hyphae in tissues are branching and septate, but the diameter and shape of the hyphae may vary from parallel walls measuring 2 ??m in diameter to irregular walls measuring 3-5 ??m in diameter. When present on short aerial hyphae, curved conidia are approximately 2.5 ??m wide and 7.5 ??m in curved length. Conidia have a more deeply basophilic center, and one or both ends are usually blunt. Although WNS is a disease of hibernating bats, severe wing damage due to fungal hyphae may be seen in bats that have recently emerged from hibernation. These recently emerged bats also have a robust suppurative inflammatory response.
