Abstract
Background and Aim: Androgenetic alopecia is an extremely common disorder affecting both men and women. The incidence is generally considered to be greater in males than females, although some evidence suggests that the apparent differences in incidence may be a reflection of different expression in males and females. This genetically determined disorder is progressive through the gradual conversion of terminal hairs into indeterminate hairs and finally to vellus hairs. Patients have a reduction in the terminal-to-vellus hair ratio, normally at least 2:1. Following miniaturization of the follicles, fibrous tracts remain. Patients with this disorder usually have a typical distribution of hair loss.
Methods: This is a cross sectional study that conducted in Isfahan health center in 2007-2008 .Using simple random sampling, we selected 1800 women in urban health center areas for hair loss. We evaluated the type of hair loss by Ludwig classification. The data was collected through administration of a specifically designed questionnaire and was analyzed using SPSS software. The chi-square and student tests were used for data analysis.
Results: According to results of this study the of 1800 women, 712 (39.6%) had hair loss. Mean age of females who had hair loss was 50.4±13 years.
Conclusion: Thyroid disorders, ferritin serum level and androgenic hormones may play role in hair loss and their existance should be assessed.

Abstract
Background and Aim: Alopecia areata is a non-scarring hair disorder. Trace elements imbalance (like zinc) has been reported as its triggering factor. In this study we compared serum zinc level in alopecia areata patients with normal values.Methods: Twenty-three female and 19 male patients with alopecia areata were recruited and their serum zinc levels were assessed using absorption spectrometery. Chi squared, t and ANOVA tests were used for statistical analysis.
Results: Sixteen patients with more extensive and prolonged disease, had serum zinc level lower than normal (70 µg/dL). The means of serum zinc levels in patients and normal population were 81.88 µg/dL and 83.5 µg/dL, respectively. This difference was not significant (P=0.668). The means of serum zinc level in different types of alopecia areata were not significantly different (P>0.05). There was an association between serum zinc level and disease duration (P=0.022).
Conclusion: Patients with more severe forms of alopecia areata had lower serum zinc level than other forms of the disease.

Abstract
Background and Aim: Cicatricial alopecia is characterized
by permanent destruction of the pilosebaceous unit, leading to
irreversible hair loss, and has primary and secondary types. Primary type,
based on predominant inflammatory infiltration in histology, is divided to
neutrophilic, lymphocytic and mix types. Decalvans folliculitis, dissecting cellulitis and
acne keloidalis are 3 subtypes of neutrophilic group. In this study frequency
of each subtype and the distribution of age, gender and duration of disease
have been reviewed.
Methods: This retrospective study was performed on patients
with clinical diagnosis of cicatricial alopecia and histologic confirmation
referred to Razi hospital in Tehran in 2005-2009.
Results: Of 135 patients with mean (mean±SD) age of 32±10.6
years, 71.9% were male and 28.1% were female. The diagnoses included decalvans
folliulitis (72.6%) with mean age of 31.89 years, dissecting cellulitis (25.0%)
with mean age of 32.4 years and acne keloidalis (1.5%) with mean age of 52
years. The mean duration of disease was 4.2±3.9 years (4.08 years in male and
4.7 years in female). The mean duration of disease in decalvans folliulitis was
4.7, in dissecting cellulitis was 1.9 and in acne keloidalis was 17.5 years.
Conclusion:
Neutrophilic scarring alopecia is more common in men and in the third decade of
age and the most common type is decalvans folliulitis.

Abstract
Background and Aim: Tinea capitis is one of the most common fungal infections in dermatology. Although the new medications and development in social health have reduced its incidence, it is still common in Iran, especially in rural areas. The aim of this study was to describe the frequency of complications of kerion.
Methods: Eighteen affected patients, who were hospitalized in dermatology ward because of kerion, in a 10-year period, were revisited and according to their medical documents, data collection forms were filled.
Results: 61.1% of the patients were younger than 10 years of age and 77.7% were male. The mean disease duration from the onset of symptoms to the time of correct diagnosis and management was 16.9 days. The frequency of scar and alopecia was equal in all groups and occurred in 100% of patients. Two patients also suffered from isolation due to scarring alopecia. Various types of medications, made no difference in the prognosis and resultant scarring alopecia.
Conclusion: The frequency and types of sequela showed no relationship with age, type of medication and duration from the onset of disease and correct management. Scar and alopecia occurred in all patients. Further investigations on the new treatment modalities are required to reduce scar formation.

Abstract
Hair loss can be viewed a problem from different perspectives: as a disease, a disorder which affects appearance of an individual, and its psychological effects. Therefore, it is crucial to determine the causes and types of hair loss. This review summarized hair loss evaluation methods with significant emphasis on their clinical aspects. According to relevant literature reviews, the major approaches to hair loss are taking medical history, primary investigations and detailed hair examination. Although several invasive and non-invasive, clinical and paraclinical examinations can be used for hair loss assessment, it is generally accepted that using clinical evaluation methods and physical examinations are more efficient. In conclusion, diagnosing hair loss is complex and sometimes time-consuming process. However, precise hair examination may lead to the suspicion of an endocrine disorder.

Abstract
Background and Aim: Alopecia Areata is a chronic inflammatory disease which involves hair follicles. The aim of this study was to assess the efficacy of oral sulfasalazine in the treatment of recalcitrant alopecia areata.
Methods: Patients with refractory alopecia areata who were eligible for the study, after providing informed consent were treated with oral sulfasalazine for 6 months. After completion of treatment, regrowth of vellus and terminal hairs were determined based on clinical examination and comparing the new photographs with the baseline ones.
Results: Sixteen patients were enrolled in the present study but only 5 patients completed it. No response was seen in 3 patients. After 4 months, 55-60% response to treatment was observed in 1 patient, but the disease relapsed at the end of fourth month. In 1 patient, 15% hair regrowth was observed but treatment was discontinued after the second month due to side effects. Side effects were observed in 2 patients.
Conclusion: Since only refractory alopecia areata patients had been enrolled to the study, the results could not be generalized to all patients with alopecia areata. Therapeutic response in the patients with alopecia areata is disappointing and any poor treatment response or failure of treatment in refractory cases of the disease cannot rule out the efficacy of the drug in the milder forms of the alopecia areata.

Abstract
Background and Aim: Androgenetic alopecia (AGA) is the most common type of alopecia in men. Currently, minoxidil is the only topical drug which has been approved by FDA for the treatment of AGA. However, its efficacy is restricted because of its low skin penetration. Since vesicular systems such as liposomes and niosomes have higher efficacy and lower adverse effects, this study was conducted to compare the efficacy of topical niosomal minoxidil with conventional minoxidil in the treatment of AGA.
Methods: This study was a randomized, controlled double-blind clinical trial. Ninety male patients with AGA according to Hamilton criteria were enrolled into this trial. The participants applied the interversion to which they were allocated twice a day, and were evaluated monthly for 6 months by a physician and patients self-assessments.
Results: Eighty-eight patients completed the trial. Mean increased hair count in niosomal minoxidil group and conventional minoxidil group in the last visit were 28.18±11.00 and 14.22±5.23, respectively (P<0.001). Moreover, evaluation of treatment response according to the patients self-assessments were 8.72±5.03 and 3.33±2.67 in niosomal and conventional minoxidil, respectively, which revealed more satisfaction in niosomal group (P=0.001). With the exception of two cases in niosomal minoxidil group whom were withdraw due to scalp itching and erthema no other adverse effect was observed in either group.
Conclusion: In the present study, application of topical niosomal minoxidil revealed an increase in the hair count in comparison with conventional minoxidil solution. Application of this new formulation for the treatment of AGA may be recommended.

Background and Aim: Cicatricial
alopecia is the result of irreversible substitution of hair follicles with
fibrotic tissue and presents as permanent loss of hair. Only a few studies
have investigated the clinical and histopathological characteristics of
cicatricial alopecia in Iran. The aim of this study was to determine the
demographic, clinical and histopathological characteristics of patients with
cicatricial alopecia who referred to our dermatology outpatient clinic in
Farshchian hospital in a two year period, and to evaluate the diagnostic
value of histopathologic criteria in diagnosing different kinds of
cicatricial alopecias.
Methods: This was a
cross-sectional study. Eighty nine patients who underwent skin biopsy due to
clinical diagnosis of cicatricial alopecia were included. Demographic and
clinical characteristics of patients as well as clinical diagnosis were
recorded and the biopsy samples were evaluated by two different pathologists
who were unaware of each other's diagnosis. Histopathological diagnosis of
patients according to each pathologist's opinion was recorded separately and
statistical analysis was performed to obtain the coincidence coefficient between
two pathological diagnosis.
Results: The most common
forms of cicatricial alopecias due to clinical and histopathological
diagnosis were: lichen planopilaris, disciod
lupus erythematosus, alopecia
areata, pseudopelade
of Brocq, folliculitis
decalvans and
central centrifugal cicatricial alopecia. Moreover,
our findings showed a powerful coincidence coefficient between clinical
diagnosis and the first pathologist diagnosis (kappa=0.836), an average to
powerful coincidence coefficient between the second pathologist diagnosis and
clinical diagnosis
(kappa=0.703) and finally an average to powerful coincidence coefficient
between the two pathologists diagnosis
(kappa=0.663).
Conclusion: Diagnosis of
cicatricial alopecia depends upon clinical and also histopathological
examination. Diagnostic value of histopathological criteria even at the end
of scarring process when there is considerable overlap between microscopic
findings of different etiologies of cicatricial alopecias is still acceptable
and there is no need to re-evaluate the biopsy specimen by a second
pathologist in order to confirm the diagnosis.

Abstract
Background and Aim: Cicatricial alopecia refers to lesions that result in permanent and irreversible hair loss and are associated with destruction of hair follicles. In this alopecias the hair follicle is replaced with connective tissue. After remission of initial infection or inflammation, hair regrowth is unlikely.
Methods: In this retrospective cross-sectional study, 222 patients with cicatricial alopecia, admitted to Farshchian Hospital, Hamadan, Iran were investigated. Hospital records of patients with cicatricial alopecia were reviewed, and their demographic as well as clinical data were extracted and entered into prepared data gathering forms.
Results: One-hundred and ten patients (49.5%) had discoid lupus erythematosus, 71 patients (31.9%) had lichen planopilaris, 23 patients (10.4%) had pseudopelade of Brocq, 11 patients (4.9%) had keratosis pilaris spinulosa decalvans and 3 patients (1.3%) had central centrifugal cicatricial alopecia. Each of alopecia mucinosa and dissecting cellulitis/folliculitis were observed in 2 patients (0.9%). The correlation between of illness, extent of disease, gender, location, occupation, and clinical features of the disease were studied.
Conclusion: Cicatricial alopecia usually results in irreversible hair loss, but early diagnosis and treatment can prevent the progression of the lesions and its complications. The diagnosis of this disease is possible with a clinicopathologic study.

Abstract
Background and Aim: Androgenetic alopecia (AGA) is the most common form of alopecia in men, worldwide and topical minoxidil appears to be the most effective and safe treatment for AGA beside oral finasteride. Safety assessment of topical minoxidil formulation could be conducted using in vivo studies on human volunteers. Using skin biophysical parameters is a fast and noninvasive method for safety assessment of topical products.
Methods: A topical combination of Minoxidil 5% solution in combination with chamomile extract from Iran’s pharmaceutical market tested on the skin of the forearm of 15 healthy volunteers. Changes in transepidermal water loss (TEWL), stratum corneum hydration, pH, melanin and hemoglobin contents have been evaluated, using biometric assessments with MPA 580 Cutometer®.
Results: There was not any significant change in skin hydration (P=0.692), TEWL (P=0.191), stratum corneum pH (P=0.613), melanin (P=0.533), and hemoglobin (P=0.579) contents before and after topical minoxidil application.
Conclusion: No significant change detected in skin erythema and assessed parameters Application of minoxidil 5% + chamomile 7% topical solution on human volunteers has not shown any adverse effects and these formulations could be recommended to use.

Abstract
Background and Aim: Androgenetic alopecia (AGA) is the most common cause of hair loss after puberty and its association with comorbid diseases including metabolic syndrome and cardiovascular diseases has become well known over the past two decades. The aim of this study was to evaluate the relationship between androgenetic alopecia with carotid artery intima media thickness as a marker for early diagnosis of atherosclerosis in women.
Methods: Fifty-four women, 27 with AGA and 27 healthy controls were enrolled in this case-control study. Demographic and clinical information of the patients were recorded in the predesigned questionnaires. Carotid intima media thickness was measured using ultrasound and the obtained data were recorded as well. Mann-Whitney and t tests were used to make comparisons between the two groups.
Results: The mean age of case and control groups were 28.8 ± 6.6 and 28.1 ± 6.7 years, respectively. No statistically significant association between AGA and carotid intima media thickness was found, although the findings showed an increase in carotid intima media thickness in patients (P>0.05) No statisctically significant association between carotid intima media thickness and the onset of disease, grade or pattern of AGA was found (P>0.05).
Conclusion: The results of this study did not show any statistically significant relationship between AGA and carotid intima media thickness. However, increased carotid intima media thickness in patients with AGA was found. Better designed studies with larger sample size are recommneded to evaluate carotid intima media thickness as a predictor for cardiovascular disease.

Abstract
Background and Aim: Hair loss is a chronic and frequent dermatological condition. It negatively affects the psychological status, social relationships and daily activities of the patients The aim of this study was to evaluate the prevalnce of depression in women with hair loss in a referral dematology clinic in Yazd, Iran.
Methods: This cross-sectional study was conducted from March 21 to June 21, 2015. Fifty-four women suffering from hair loss referred to the Shahid Sadoughi Dermatology Clinic in Yazd were recruited. Depression assessed by using the Beck Depression Inventory. Data were analyzed using versioin 18 of PASW (IBM Corp., Armonk, NY, USA) and Fisher's exact test was used for comparing proportions in different groups.
Results: The mean ± standard deviation score of depression was 16.1±13.5. The study showed that 67% of hair loss patients were experiencing depression. While not statitically significant, frequency of depression seems to be associated with the level of education (P=0.052). There was no associatioin between the frequency of depression and age, marital status, previous medical history, or drug use.
Conclusion: This study showed that depression is highly frequent among women with hair loss. Beauty is crucial for most women and feeling the lack of beauty and not being attractive decrease their social interaction. More effective treatment of hair loss may improve depression and community relations, and consequently result in higher quality of life in a hair loss patient.

Abstract
Background and Aim: Cicatricial (scarring) alopecia is a group of disorders in which permanent hair loss results from replacement of hair follicles by fibrosis or hyalinized collagen, which includes two types: primary such as discoid lupus erythematosus (DLE), lichen plano pilaris (LPP), frontal fibrosing alopecia (FFA), Folliculitis decalvans, and secondary like kerion and burn. The aim of this study was to evaluate the frequency of different types of scarring alopecia in patients referred to Imam Reza Dermatology Clinic in Ardebil in 1397.
Methods: In this descriptive cross-sectional study, 96 patients referred to the dermatology clinic of Imam Reza Hospital, Ardebil, Iran, were evaluated. Epidemiologic and pathologic causes of primary and secondary cicatricial alopecia were analyzed using descriptive statistics in SPSS version 16 software.
Results: The most common causes among patients with primary cicatricial alopecia were DLE (51.16%), LPP (6.25%), acne keloidalis (4.16%), folliculitis decalvans (2.08%), FFA (2.08%) and pseudopelade of Brocq 1.04%). In patients with secondary cicatricial alopecia the most common causes were kerion (55.2%), followed by morphea cutaneous lymphoma and burn (1.04%).
Conclusion: Considering that the majority of patients in rural area had kerion (92.45%), we can prevent the spread of the disease by improving hygiene standards as an important factor in controlling this disease in order to early diagnosis and treatment.

Abstract
Background and Aim: Trichoscopy is a non-invasive diagnostic tool for hair diseases. The aim of this study was to evaluate the trichoscopic findings in different types of alopecia.
Methods: This cross-sectional study was conducted on 155 alopecia patients referring to Hamadan’s Sina hospital from March 2019 to July 2020. The patients were recruited after giving written informed consent. Scalp biopsy was performed to confirm the diagnosis and trichoscopic evaluation was then carried out. Trichoscopic findings along with demographic data were recorded. Data was analyzed using SPSS 16.0 software and appropriate statistical methods.
Results: A total of 155 patients including 79 males and 76 females were included in the study. The most common trichoscopic finding in alopecia areata was vellus hair (95.5%). The most common finding in androgenetic alopecia (AGA) was hair shaft thickness heterogeneity which was observed in all AGA patients. The most common findings in telogen effluvium (TE) were single hair pilosebaceous units, peripilar sign, thin terminal hairs and upright regrowing hairs which were observed in all TE patients. The most common finding in lichen planopilaris was perifollicular scaling (81.8%). The most common findings in discoid lupus erythematosus were large yellow dots (100%) and fine scaling (100%). Black dot was the most prevalent finding in tinea capitis (85.7%).
Conclusion: Trichoscopy ,as a non-invasive tool, could be helpful in differentiating different types of alopecia.

Abstract
Background and Aim: Alopecia by reduction of hair follicles at the wound healing site is a complication of cryosurgery that creates an unpleasant appearance in the scar of healed tissue. The aim of this study was to evaluate the effect of low level laser on preventing necrosis of hair follicles and increasing hair follicles in cryosurgery induced wounds.
Methods: Fifty male Wistar rats were randomly divided into 2 main experimental and control groups (with and without low power laser) and 5 subgroups. Histopathological examination of the amount of hair follicle count and angiogenesis at intervals of 3, 7, 14, 21 and 28 days was performed in the laboratory. SPSS software was used for statistical analysis.
Results: There was no significant difference in the angiogenesis had significantly index between the main groups on days 14 and 21 (P>0.05), but on days 3, 7 and 28, the experimental group had significantly higher angiogenesis than the control group. Throughout the days, both groups showed a significant increase in angiogenesis (P<0.05), except for the third and seventh days in the control group, and in both groups between the 21st and 28th days (P>0.05). In the comparison of hair follicle index, there was an increase on all days, which was significantly higher in the experimental group than the control group (P<0.05). However, no statistical difference was observed between the third and seventh days (P>0.05).
Conclusion: The use of low-power lasers on cryosurgery induced wounds with scars and alopecia can prevent hair follicles necrosis and subsequent increase in their numbers in rats.

Abstract
Alopecia areata (AA) is a sudden non-scarring hair loss that can be seen in any hairy area in the form of round or oval patches. It is an autoimmune disorder with an immunological response against hair follicles that is caused by genetic and environmental factors. The prevalence of AA is about 0.1% to 0.2% worldwide. Depending on the severity of the disease and sites of involvement, it can be divided into: Alopecia with Patchy pattern, alopecia reticularis, alopecia totalis, alopecia universalis, alopecia ophiasis, alopecia sisiapho, diffuse type and perinevoid alopecia areata. There are various treatment options for AA, but once terminated, they have a high recurrence rate. AA is known for the infiltration of T lymphocytes around the hair follicle bulb, and corticosteroids are its main treatment. Another treatment is topical immunotherapy, the most important of which is Diphenylcyclopropenone (DPCP). It is used in cases that have more than 50% hair loss or are resistant to treatment. The exact DPCP mechanism of action is not well understood, but it may have some kind of antigenic competition and reduce the production of anti-hair follicle antibodies. It can alter the immune response in the skin and alter the ratio of CD4 to CD8 cells around the hair follicle in a way that enhances healing of the disease. It is stated that the rate of hair regrowth in DPCP treatment is about 50% on average. In this article, we review the latest findings of about AA and discuss its therapeutic aspects, especially with DPCP.

Abstract
Background and Aim: Androgenetic alopecia is a type of androgen and genetic dependent hair loss and although it is more of a beauty issue, but in recent years studies have shown that this type of alopecia is associated with underlying disorders such as coronary artery disease. The aim of this study was to evaluate the frequency of androgenetic alopecia in hospitalized patients and its relationship with the history of coronary heart disease and its risk factors.
Methods: In this cross-sectional descriptive-analytic study, 250 patients (125 women and 125 men) admitted to Shahid Mostafa Khomeini Hospital in Tehran from October to December 2020 were examined and after examination and data collection, the data were analyzed using SPSS statistical software SPSS Statistics 25 version.
Results: The prevalence of alopecia was generally 46.8% in hospitalized patients, 61.6% in men and 32% in women. The prevalence of coronary heart disease in hospitalized patients was 25.6%, 34.4% in men and 16.8% in women. In patients with alopecia, the frequency of history of coronary heart disease was 39.31%, the history of hypertension was 20.8%, history of hyperlipidemia was 17.2%, history of diabetes was 14.4% and the smoking history was 15.6%. All of these factors were significantly associated with alopecia, except for smoking.
Conclusion: According to the results of this study, the frequency of androgenetic alopecia in patients admitted to the hospital is common and its prevalence in men is more than twice that of women. History of coronary heart disease and its risk factors in patients with alopecia are high, and have a significant relationship with it. This can be important and help in screening and early diagnosis of coronary heart disease and its subsequent prevention.

Abstract
Background and Aim: Hair loss is one of the most common problems among the skin and hair related diseases. Hair loss can lead to anxiety, depression, low self-esteem and dissatisfaction with appearance.
Methods: Patients with androgenetic alopecia who met the eligibility criteria entered the study. Participants were asked to randomly apply a solution of valproic acid 8.3% or a solution of minoxidil 5% on the affected areas according to the treatment protocol (twice a day). Before and 2 months after treatment, the participants were evaluated. The studied indices included the number of hair follicles in the specified area, the number of velus hairs, the number of terminal hairs, the average hair thickness, and the percentage of hairs in the anagen and telogen phases, as well as the skin reactions in the area. Hairs were examined at the beginning of the study and at 2 months after treatment using Foto Finder-trichoscale device.
Results: Two months after treatment compared to baseline in the valproic group, anagen hair count index (P=0.02), general hair count index (P=0.03), and terminl hair count index (P=0.012) showed significant changes. While telogen hair count (P=0.059) and vellus hair count (P=0.097) did not show significant changes. These changes were more significated in minoxidil group.
Conclusion: 8.3% valproic acid solution showed positive effects in increasing the number of hairs and decreasing the percentage of telogen hairs. Due to the delayed mechanism of valproic acid, the duration of treatment with this compound should be considered longer than minoxidil as a positive control.
