ABSTRACT
A beleza está diretamente ligada ao aspecto dos cabelos, em todos os tempos e todas as culturas. O cabelo ao longo da vida é sujeito a vários tipos de mudanças, sejam elas naturais ou artificiais, conduzidas por uma vontade de mudar, muitas vezes, seja por representar uma nova fase, como também é símbolo de autocuidado, vaidade, sucesso, possuem significativa importância na aparência e autoestima das pessoas e, por isso, a queda capilar pode atingir a qualidade de vida do indivíduo. Neste sentido, o objetivo deste estudo foi avaliar procedimentos estéticos minimamente invasivos e não cirúrgicos com ênfase na queda capilar. Para tanto, foi realizada uma revisão bibliográfica integrativa, de caráter descritivo nas principais bases de dados em saúde: SciELO, Google Acadêmico, PubMed e livros de medicina, nos idiomas português, inglês e espanhol, considerando o período de 2007 a 2022. De acordo com o último censo da Sociedade Brasileira de Dermatologia, a queixa de alopecia está entre as dez mais frequentes nos consultórios dermatológicos. As doenças capilares mais importantes estão divididas em dois grupos, as cicatriciais quando a perda de cabelo é acompanhada por cicatrizes resultando em calvície permanente, e as não cicatriciais onde a calvície não é permanente levando a diminuição e o afinamento gradual do cabelo. A alopecia não cicatricial é a mais frequente e as mais comuns entre elas são a alopecia androgenética e o eflúvio telógeno. Muitos pacientes procuram tratamento para melhorar a aparência e a autoestima, que podem estar relacionados a quadros de ansiedade e depressão. Esses tratamentos devem ser individualizados, onde se deve avaliar as características individuais de cada paciente. Os tratamentos capilares estéticos podem contribuir de forma significativa para a redução da baixa autoestima, contribuindo para recuperação da autoconfiança através do crescimento capilar proporcionado pela estética. Sendo assim, conclui-se que os resultados coletados na revisão de literatura foram satisfatórios, de forma onde mostra que os medicamentos, suplementos e tratamentos estéticos na queda capilar vem evoluindo cada vez mais. Contudo, mais estudos acerca do assunto são necessários.
Beauty is directly linked to the appearance of hair, in all times and all cultures. Hair throughout life is subject to various types of changes, whether natural or artificial, driven by a desire to change, often because it represents a new phase, as it is also a symbol of self-care, vanity, success, they have significant importance in people's appearance and self-esteem and, therefore, hair loss can affect the individual's quality of life. In this sense, the objective of this study was to evaluate minimally invasive and non- surgical aesthetic procedures with an emphasis on hair loss. To this end, an integrative bibliographic review was carried out, of a descriptive nature, in the main health databases: SciELO, Google Scholar, PubMed and medical books, in Portuguese, English and Spanish, considering the period from 2007 to 2022. According to the latest census by the Brazilian Society of Dermatology, the complaint of alopecia is among the ten most frequent complaints in dermatological offices. The most important hair diseases are divided into two groups, scarring when hair loss is accompanied by scars resulting in permanent baldness, and non-scarring where baldness is not permanent leading to gradual thinning and thinning of the hair. Non-scarring alopecia is the most frequent and the most common among them are androgenetic alopecia and telogen effluvium. Many patients seek treatment to improve their appearance and self-esteem, which may be related to anxiety and depression. These treatments must be individualized, where the individual characteristics of each patient must be evaluated. Aesthetic hair treatments can contribute significantly to reducing low self-esteem, contributing to the recovery of self-confidence through hair growth provided by aesthetics. Therefore, it is concluded that the results collected in the literature review were satisfactory, in a way that shows that medicines, supplements and aesthetic treatments in hair loss have been evolving more and more. However, more studies on the subject are needed.

Estos tratamientos deben ser individualizados, donde se deben evaluar las características individuales de cada paciente. Los tratamientos capilares estéticos pueden contribuir significativamente a la reducción de la baja autoestima, contribuyendo a la recuperación de la confianza en uno mismo gracias al crecimiento del cabello que proporciona la estética. Por lo tanto, se concluye que los resultados recogidos en la revisión bibliográfica fueron satisfactorios, mostrando que los medicamentos, suplementos y tratamientos estéticos para la caída del cabello están evolucionando cada vez más. Sin embargo, son necesarios más estudios sobre el tema.

Objective To determine mercury contents in pair in cord blood,fetal hair,placenta and maternal scalp hair,and to analyze the correlation among them and the effect of mercury exposure risk factors in the mercury contents of samples.Methods Puerperants in the hospital,who lived in the local area without history of major diseases during the whole pregnancy,were investigated by questionnaire composed to several health factors.Cord blood,fetal hair,placenta and maternal scalp hair of these puerperal and their neonates (polyembryony and birth defects excluded) were collected to determine mercury content in pairs.Results The mean mercury contents of cord blood,fetal hair,placenta and maternal scalp hair in 303 samples were 1.65 μg/kg,234.58 μg/kg,3.85 μg/kg,497.62 μg/kg,respectively.Fifty percentile of them were 1.72 μg/kg,252.24 μg/kg,3.98 μg/kg,508.88 μg/kg,respectively.There were direct correlations between mercury in cord blood and that in fetal hair,mercury in cord blood and that in placenta,mercury in cord blood and that in maternal scalp hair,mercury in fetal hair and that in placenta,mercury in fetal hair and that in maternal scalp hair,mercury in maternal scalp hair and that in placenta(all P ＜ 0.05).The mercury contents in cord blood,fetal hair and maternal scalp hair of those living nearby factories involved in mercury,higher intake fish during the pregnancy,firing coal and consumption of whiting cosmetics and smoking were determined as (2.24 ± 0.20) μg/kg,(315.65 ± 35.31) μg/kg and (663.53 ± 71.83) μg/kg.The mercury in those without the high risk factors mentioned above were(1.62 ± 0.16) μg/kg,(245.79 ± 28.21) μg/kg and (499.39 ± 47.72) μg/kg.There was a significant difference between 2 groups(all P ＜ 0.01).Conclusions In addition to control industrial pollution,pregnant women should avoid the above-mentioned high risk factors and pay more attention to health care during pregnancy.The mercury content in cord blood is highly correlated with the mercury in fetal hair,and that in placenta and in maternal scalp hair.The 2 kinds of detection both can achieve the purpose of monitoring mercury intrauterine exposure conditions.
ABSTRACT
BACKGROUND: Nowadays, although its clinical value remains controversial institutions utilize hair mineral analysis. Arguments about the reliability of hair mineral analysis persist, and there have been evaluations of commercial laboratories performing hair mineral analysis. OBJECTIVE: The objective of this study was to assess the reliability of intra-laboratory and inter-laboratory data at three commercial laboratories conducting hair mineral analysis, compared to serum mineral analysis. METHODS: Two divided hair samples taken from near the scalp were submitted for analysis at the same time, to all laboratories, from one healthy volunteer. Each laboratory sent a report consisting of quantitative results and their interpretation of health implications. Differences among intra-laboratory and interlaboratory data were analyzed using SPSS version 12.0 (SPSS Inc., USA). RESULTS: All the laboratories used identical methods for quantitative analysis, and they generated consistent numerical results according to Friedman analysis of variance. However, the normal reference ranges of each laboratory varied. As such, each laboratory interpreted the patient's health differently. On intra-laboratory data, Wilcoxon analysis suggested they generated relatively coherent data, but laboratory B could not in one element, so its reliability was doubtful. In comparison with the blood test, laboratory C generated identical results, but not laboratory A and B. CONCLUSION: Hair mineral analysis has its limitations, considering the reliability of inter and intra laboratory analysis comparing with blood analysis. As such, clinicians should be cautious when applying hair mineral analysis as an ancillary tool. Each laboratory included in this study requires continuous refinement from now on for inducing standardized normal reference levels.

This study was undertaken to investigate mineral changes in weathered scalp hair after burial. EDX (energy dispersive X-ray spectroscopy) analysis was performed to measure the presence of minerals on the hair surface. Twelve scalp hairs, buried for 5-40 years, were chosen from deceased individuals buried in tombs in Soha-Ri, Kyonggi-Do, and other regions in Korea. Three normal hairs were used as the control group. EDX data showed that carbon, oxygen, and sulfur were detected in hair collected from all three burial grounds. In contrast, calcium was only detected in hair collected from tombs in Soha-ri. The amounts of calcium and sulfur were found to decrease with time for hair collected from tombs in Soha-ri. Similar results were observed with sodium for hair collected from other regions. These results show region specific mineral detection and a decrease in the concentration of minerals with time. Consequently, it is suggested that changes in minerals concentration in weathered hair could be used as basic data in the field of forensic medicine.

This study was undertaken to investigate the morphological changes of scalp hair according to weathering after burial and to offer basic data for forensic science. To examine the effect of weathering degree, the 51 human scalp hairs buried after death were taken from deceased individuals in tombs in Korea. The morphological changes in weathering hair shafts of the scalp were investigated using the transmission electron microscopes (TEM). There were little morphological differences of weathering depending on the burial period. The weathering changes includes detachment of cuticle layer, aggregation of macrofibril and hollow formation in the cortex according to the burial period. These results could provide basic data to the field of forensic medicine.

Heterochromia is the presence of more than one distinct color of hair in a person. It is known to be related with genetic background, but definite cause of this disorder has not been found. Several cases of heterochromia of the scalp hair have been reported and each case has different pattern, distribution and course. We report a 6-month-old infant with acquired transient heterochromia of the scalp hair who has unusual pattern and course different from previously reported case.

This study was conducted to measure the lead, cadmium and mercury levels in the scalp hair, cerebellum, cerebrum, heart, kidney, liver, lung, and spleen of the 60 Korean autopsy subjects and assess the relationship among those samples. The mean lead level in the scalp hair was 12.29+/-12.51 microgram/g and no significant difference was detected in lead concentrations between the two sexes. Among the internal organ tissues the cerebrum contained the highest level of lead. This is followed by the cerebellum, spleen and liver respectively. After which the kidney and lung showed a close similarity at relatively low concentrations and the heart contained the lowest concentration. There was also no significant variation found between sexes in a comparison of lead in the internal organ tissues. The concentrations of cadmium in kidney were 127.33+/-89.36 microgram/g and considerably higher than those in the other internal organs. The liver contained the next highest level of cadmium. In both sexes, the consistent difference was noted in the cadmium concentrations of the kidney, heart and spleen. Yet female cadmium level was higher than the male's. The concentrations of mercury in the kidney and liver were 1.26+/-2.89 microgram/g, 0.59+/-0.54 microgram/g and considerably higher than those in the other internal organs. The mean mercury level in the scalp hair was 1.29+/-0.64 microgram/g and no marked difference was noted in both sexes. The lead concentration in the spleen increased with advancing age, though not statistically significance, and most of the internal organ tissues that were examined showed no evidence of increased lead concentration with age. The kidney, cerebrum, spleen and cerebellum showed increased cadmium concentrations with age. Also as well as the internal organ tissues that were examined showed no evidence of increased mercury concentration with age. The lead concentrations in the liver and lung were higher in the urban area than in the rural area, but the lead concentration in the kidney was higher in the rural area. No difference was noted in tissue cadmium and mercury concentrations as to the area of residence either. The physical workers had greater concentrations of lead in cerebellum than did housewives or the unemployed. Yet no difference was noted in the other tissues between the two groups. In the cerebellum, cerebrum, heart, and spleen, the physical workers had greater concentrations of cadmium than students or mental workers. Also physical workers had greater concentrations of cadmium in lung than housewives or the unemployed. In contrast to lead and cadmium, both the housewives and the unemployed had higher concentrations of mercury in cerebellum and cerebrum than physical workers, but there was no difference was noted in the other tissues between the two groups. In the lead concentration, there was no statistically significant correlation between the scalp hair and examined internal organ tissues. There was a close relationship between lead levels in cerebellum and cerebrum (r=0.465, p<0.01), as well as a relationship between the cerebellum and the kidney(r=0.300, p<0.05). There was no statistically significant correlation between the cadmium levels in the scalp hair and in the examined internal organ tissues. Positive correlations were found between the cadmium concentrations in the cerebellum and the cerebrum(r=0.5543, p<0.01), heart(r=0.480, p<0.01), kidney(r=0.376, p<0.01) and spleen(r=0.408, p<0.01). Also positive correlation was found between in the cerebrum and the heart(r=0.377, p<0.01), kidney(r=0.484, p<0.01), liver(r=0.265, p<0.05), lung(r=0.458, p<0.01) and spleen (r=0.483, p<0.01). There was also no statistically significant correlation between the mercury levels in the scalp hair and in the examined internal organ tissues. Positive correlation was found between the mercury concentrations in the cerebellum and cerebrum(r=0.760, p<0.01), heart(r=0.270, p<0.05), liver(r=0.425, p<0.01), lung (r=0.488, p<0.01) and spleen (r=0.534, p<0.01), and also positive correlation was found between in the cerebrum and heart(r=0.376, p<0.01), liver(r=0.350, p<0.01), lung(r=0.554, p<0.01) and spleen (r=0.489, p<0.01). Various epidemiological studies reported usefulness and reliability of using scalp hair as a monitor of a environmental pollutants. In this study, there was statistically significant correlation of lead, cadmium and mercury levels in most of the tissues that were examined, but there was no statistically significant correlation between the lead, cadmium and mercury levels in the scalp hair and most of examined internal organ tissues. The findings of this study would suggest that it is still uncertain to using scalp hair as a biological monitoring.

Trichorhinophalangeal syndrome (TRPS) was first described in 1966 by Giedion. It is a rare genetic disease and divided into two groups : TRPS type I and TRPS type II. TRPS type I is an autosomal dominant inherited disorder, defined by three characteristic findings : first, sparsely distributed brittle and slow-growing scalp hair, second, a bulbous pear-shaped nose with an elongated philtrum, third brachydactyla with angular deformities. The characteristic radiological features of the hands include cone shaped epiphysis of the proximal interphalangeal joints. Most TRPS type II is sporadic and shows multiple exosteosis, mental retardation and microcephaly in addition to the three chracteristic findings of TRPS type I . A 20-year-old female visited our department for the evaluation of her sparse, slow-growing scalp hair. She also had a bulbous pearshaped nose, ulnar deviated fingers and shortened both hallux. Some relatives of patients show similar symptoms of scalp hair. A Radiologic aly, histopathologic aly and chromosomal study were done, and we established the diagnosis, TRPS type I.

This study was conducted to measure the lead level in the blood, scalp hair and toenail of the elementary schoolchildren and assess the relationship among those samples. Lead concentration of the blood, scalp hair and toenail was measured for l00(male 50, female 50) fourth grade elementary schoolchildren in Taegu city. The mean lead level in the blood, scalp hair and toenail was 6.00+/-2.44 microgram/dl, 6.28+/-3.54 microgram/dl 6. 68 and 7.33+/-3.18 microgram/g. The mean lead level in the blood of schoolboys was 6.43+/-2.77 microgram/dl and that of schoolgirls was 5.59+/-2.01 microgram/dl. The mean lead level in the scalp hair of schoolboys was 7.66+/-2.97 microgram/dl and that of schoolgirls was 6.88+/-3.54 microgram/g. The mean lead level in the toenail of schoolboys was 8.19+/-3.5 microgram/g and that of schoolgirls was 6.47+/-2.52 microgram/g and their difference was statistically significant. In schoolboys, the correlation coefficient between the lead level in the blood and scalp hair was 0.4909, and the data were fitted best by the regression equation Y=0.5255X+4.2810, where Y and X are scalp hair and blood concentration. In schoolgirls the correlation coefficient between the lead level in the blood and scalp hair was 0.3778, and the data were fitted best by the regression equation Y=0.6655X+2.9632, where Y and X are scalp hair and blood concentration. In schoolboys. the correlation coefficient between the lead level in the blood and in the toenail was 0.5533, and the data were fitted best by the regression equation Y=0.7076X+3.6472, where Y and X are toenail and blood concentration. In schoolgirls the correlation coefficient between the lead level in the blood and in the toenail was 0.2738, and the data were fitted best by the regression equation Y=0.3431X+4.5570 where Y and X are toenail and blood concentration. In schoolboys, the correlation coefficient between the lead level in the scalp hair and in the toenail, in the schoolboys was 0.4148, and the data were fitted best by the regression equation Y=0.4956X+4.3986, where Y and X are toenail and scalp hair concentration. In schoolgirls the correlation coefficient between the lead level in the scalp hair and in the toenail 0.1159, and the data were fitted best by the regression equation Y=0.0825X+5.9214 here Y and X are toenail and scalp hair concentration. Correlation among lead concentration in the blood, scalp hair and toenail of schoolchildren were statistically significant except between scalp hair and toenail in schoolgirls. These finding suggest that blood, scalp hair and toenail can be used substitutive samples between each others.

I report a case of scalp hair loss and nail destruction as possible side effects of anabolic androgenic steroid (AAS) doping in a Japanese athlete. The patiet, a 27-year-old man, was an amateur bodybuilder who won the championship in a bodybuilding contest. However, he tested positive in a doping test for drostanolone and stanozolol, and was deprived of his championship.<BR>In Japan, positive results in doping tests are very rare. The patient suffered from loss of scalp hair and destruction of the nails before the contest. In addition, he presented with hoarseness and soft tumors of the lower extremities. Laboratory data showed hypotestos-onemia caused by AAS doping. However, a hCG test revealed that he still had positive of sex function capacity. Therefore the patients natural course was observed without medical treatment, and the symptoms were resolved within four months after the contest. This is considered to be the first case of nail destruction caused by AAS doping reported in the world.
ABSTRACT
Hair from 16 scalps of different ages (from 5 months to 77 years old) have been observed with SEM. The surface ultrastructure of the cuticle of the hair shaft is distinctly seen. The cuticles are arranged like shingles. Their free margins direct toward the end of the hair. The appearance and diameter of the shaft vary from age to age. The hair shaft of fetus is very fine. The cuticles are so broad that a single cuticle may encircle the shaft. They are parallel to each other. The intervals between successive free margins of cuticles are wide. Their free margin is smooth. The hair shaft of a 5-year old child is coarse. The cuticles vary in size. It requires a number of cuticles to encircle the shaft. The free margin becomes jagged and curved with microprotrusions on it. The intervals between free margins of the cuticles vary in width. The hair shaft of the youths is coarser. The cuticles are broad and arranged regularly. The intervals between free margins of the cuticles are comparatively narrow. There are numerous well developed microprotrusions on the free margin. The hair shaft of the middle aged is the coarsest and the intervals between free margins of the cuticles are the narrowest of all. There are less microprotrusions than those of the youths'. They are getting less and less, so that the free margin is partly smooth. Many cracks perpendicular to the free margin appear apparently and much debris fallen from the cuticle is attached to the surface of the the shaft. Sometimes falling of a whole cuticle may be observed. The hair shaft of the aged people is finer than that of the youths'. The intervals between cuticles with loose squamous arrangement are wider than those seen in the young and middle aged people. The free margin is usually smooth with only a few microprotrusions if any. Sometimes big and deep holes may be found on the surface of white hair. It is considered that the diameter of hair shaft, the size and arrangement of cuticles, the characteristic structures of free margin, the number of microprotrusions and with or without small debris attached to or holes appeared on the shaft are all related to age.
