Review
BACKGROUND
Satoyoshi syndrome (SS) [OMIM 600705; ORFHA 3130] is a multisystemic disease with a probable autoimmune basis, whose main symptoms are muscle spasms, alopecia, diarrhea and skeletal alterations. Chronic diarrhea may be severe and result in malnutrition, anemia, growth retardation, cachexia, disability and even death. However, to date, no review of the digestive symptoms has been carried out.
METHODS
A search was performed in MEDLINE, Scopus and Web of Science databases. Cases of SS, without language or date restrictions, were recorded. Sixty-seven cases of SS were found up until December 2019. Thirty-nine cases described gastrointestinal manifestations.
RESULTS
Chronic diarrhea was the main digestive symptom (92.3%). Other symptoms such as abdominal pain (15.4%), nausea (7.7%) and vomiting (7.7%), were less frequent. The D-xylose test was positive in 10 out of 12 patients, and 9 out of 13 cases showed a flattened oral glucose tolerance test suggesting carbohydrate malabsorption. Antinuclear antibodies were detected in 8 out of 16 cases. Antibodies to stomach or duodenum tissue lysates were also detected by Western blot. Histological data revealed predominantly lymphoplasmacytic inflammatory infiltrate that can affect any section of the digestive tract. In 6 out of 10 patients, diarrhea improved with a treatment regimen that included corticosteroids. Other treatments, such as methotrexate, carbohydrate restricted diets or otilonium bromide, improved digestive symptoms in isolated patients. Improvement of symptoms up to three years of follow-up has been described. None of the three patients who died had received corticosteroids or immunosuppressants.
CONCLUSION
Chronic diarrhea with malabsorption is one of the most disabling symptoms in SS. The early recognition of this disease is essential for immunosuppressive treatment and a better outcome.

Review
BACKGROUND
Alopecia Areata (AA) is found to be the most prevalent autoimmune disorder amongst the general population. It was observed that AA patients are at a significantly higher risk of developing obstructive sleep apnea and non-apneic insomnia than patients without AA. On the contrary, patients with identified sleep disorders were found to be more prone to developing AA as compared to the patients without sleep disorders. This study, therefore, validated the hypothesis of a bidirectional association between AA and sleep disorders.
AIMS
In this systematic review, our primary aim is to assess the prevalence of sleep disorders in Alopecia Areata patients while also assessing the inverse relationship between the two disorders.
METHODS
A literature search of MEDLINE, Google Scholar and Cochrane CENTRAL was performed from their inception to April 2022. Articles were selected for inclusion if they met the following eligibility criteria: (a) Studies enrolling patients having alopecia areata to assess the sleep quality. (b) Studies assessing the risks of alopecia areata in individuals with sleep disorder (c) Studies evaluating the bidirectional association between alopecia areata and sleep quality. Case reports, commentaries, and editorials were excluded. The outcomes of recruited studies were qualitatively synthesised and study findings are summarized in the results section and tabulated in summary tables.
RESULTS
Our search on electronic databases yielded 1562 articles. After abstract screening and full text review, 5 cross sectional and 3 cohort studies are included in this systematic review. Cases with PSQI scores higher than 5 and 6 were found to be in greater numbers amongst the AA patient population when compared to the control population ( < 0.001). Moreover, studies showed that patients with sleep disorders were greatly predisposed to develop subsequent AA as compared to patients without sleep disorders (aHR 4.70; 95% CI 3.99-5.54) (P < 0.0001).
CONCLUSION
The findings from our results display a significant bi-directional cause-effect relation between AA and sleep disorders. However, more large-scale observational studies on this subject are required to further validate our findings.

Review
Acne keloidalis nuchae (AKN) is a chronic inflammatory condition that leads to fibrotic plaques, papules and alopecia on the occiput and/or nape of the neck. Traditional medical management focuses on prevention, utilization of oral and topical antibiotics, and intralesional steroids in order to decrease inflammation and secondary infections. Unfortunately, therapy may require months of treatment to achieve incomplete results and recurrences are common. Surgical approach to treatment of lesions is invasive, may require general anesthesia and requires more time to recover. Light and laser therapies offer an alternative treatment for AKN. The present study systematically reviews the currently available literature on the treatment of AKN. While all modalities are discussed, light and laser therapy is emphasized due to its relatively unknown role in clinical management of AKN. The most studied modalities in the literature were the 1064-nm neodymium-doped yttrium aluminum garnet laser, 810-nm diode laser, and CO2 laser, which allow for 82-95% improvement in 1-5 sessions. Moreover, side effects were minimal with transient erythema and mild burning being the most common. Overall, further larger-scale randomized head to head control trials are needed to determine optimal treatments.

Meta-Analysis Review
BACKGROUND
Post-surgical radiotherapy (RT) in combination with chemotherapy is considered as standard of care for medulloblastoma in children. Chemotherapy has been introduced to improve survival and to reduce RT-induced adverse effects. Reduction of RT-induced adverse effects was achieved by deleting (craniospinal) RT in very young children and by diminishing the dose and field to the craniospinal axis and reducing the boost volume to the tumour bed in older children.
PRIMARY OBJECTIVES
1. to determine the event-free survival/disease-free survival (EFS/DFS) and overall survival (OS) in children with medulloblastoma receiving chemotherapy as a part of their primary treatment, as compared with children not receiving chemotherapy as part of their primary treatment; 2. to determine EFS/DFS and OS in children with medulloblastoma receiving standard-dose RT without chemotherapy, as compared with children receiving reduced-dose RT with chemotherapy as their primary treatment.
SECONDARY OBJECTIVES
to determine possible adverse effects of chemotherapy and RT, including long-term adverse effects and effects on quality of life.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2013, Issue 7), MEDLINE/PubMed (1966 to August 2013) and EMBASE/Ovid (1980 to August 2013). In addition, we searched reference lists of relevant articles, conference proceedings and ongoing trial databases (August 2013).
SELECTION CRITERIA
Randomised controlled trials (RCTs) evaluating the above treatments in children (aged 0 to 21 years) with medulloblastoma.
DATA COLLECTION AND ANALYSIS
Two review authors independently performed study selection, data extraction and risk of bias assessment. We performed analyses according to the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. Where possible, we pooled results.
MAIN RESULTS
The search identified seven RCTs, including 1080 children, evaluating treatment including chemotherapy and treatment not including chemotherapy. The meta-analysis of EFS/DFS not including disease progression during therapy as an event in the definition showed a difference in favour of treatment including chemotherapy (hazard ratio (HR) 0.70; 95% confidence interval (CI) 0.54 to 0.91; P value = 0.007; 2 studies; 465 children). However, not including disease progression as an event might not be optimal and the finding was not confirmed in the meta-analysis of EFS/DFS including disease progression during therapy as an event in the definition (HR 1.02; 95% CI 0.70 to 1.47; P value = 0.93; 2 studies; 300 children). Two individual studies using unclear or other definitions of EFS/DFS also showed no clear evidence of difference between treatment arms (one study with unclear definition of DFS: HR 1.67; 95% CI 0.59 to 4.71; P value = 0.34; 48 children; one study with other definition of EFS: HR 0.84; 95% CI 0.58 to 1.21; P value = 0.34; 233 children). In addition, it should be noted that in one of the studies not including disease progression as an event, the difference in DFS only reached statistical significance while the study was running, but due to late relapses in the chemotherapy arm, this significance was no longer evident with longer follow-up. There was no clear evidence of difference in OS between treatment arms (HR 1.06; 95% CI 0.67 to 1.67; P value = 0.80; 4 studies; 332 children). Out of eight reported adverse effects, of which seven were reported in one study, two (severe infections and fever/neutropenia) showed a difference in favour of treatment not including chemotherapy (severe infections: risk ratio (RR) 5.64; 95% CI 1.28 to 24.91; P value = 0.02; fever/neutropenia: RR not calculable; Fisher's exact P value = 0.01). There was no clear evidence of a difference between treatment arms for other adverse effects (acute alopecia: RR 1.00; 95% CI 0.92 to 1.08; P value = 1.00; reduction in intelligence quotient: RR 0.78; 95% CI 0.46 to 1.30; P value = 0.34; secondary malignancies: Fisher's exact P value = 0.5; haematological toxicity: RR 0.54; 95% CI 0.20 to 1.45; P value = 0.22; hepatotoxicity: Fisher's exact P value = 1.00; treatment-related mortality: RR 2.37; 95% CI 0.43 to 12.98; P value = 0.32; 3 studies). Quality of life was not evaluated. In individual studies, the results in subgroups (i.e. younger/older children and high-risk/non-high-risk children) were not univocal.The search found one RCT comparing standard-dose RT with reduced-dose RT plus chemotherapy. There was no clear evidence of a difference in EFS/DFS between groups (HR 1.54; 95% CI 0.81 to 2.94; P value = 0.19; 76 children). The RCT did not evaluate other outcomes and subgroups.The presence of bias could not be ruled out in any of the studies.
AUTHORS' CONCLUSIONS
Based on the evidence identified in this systematic review, a benefit of chemotherapy cannot be excluded, but at this moment we are unable to draw a definitive conclusion regarding treatment with or without chemotherapy. Treatment results must be viewed in the context of the complete therapy (e.g. the effect of surgery and craniospinal RT), and the different chemotherapy protocols used. This systematic review only allowed a conclusion on the concept of treatment, not on the best strategy regarding specific chemotherapeutic agents and radiation dose. Several factors complicated the interpretation of results including the long time span between studies with important changes in treatment in the meantime. 'No evidence of effect', as identified in this review, is not the same as 'evidence of no effect'. The fact that no significant differences between treatment arms were identified could, besides the earlier mentioned reasons, also be the result of low power or too short a follow-up period. Even though RCTs are the highest level of evidence, it should be recognised that data from non-randomised studies are available, for example on the use of chemotherapy only in very young children with promising results for children without metastatic disease. We found only one RCT addressing standard-dose RT without chemotherapy versus reduced-dose RT with chemotherapy, so no definitive conclusions can be made. More high-quality research is needed.

Meta-Analysis Review
Irinotecan chemotherapy combined with fluoropyrimidines versus irinotecan alone for overall survival and progression-free survival in patients with advanced and/or metastatic colorectal cancer.
BACKGROUND
Chemotherapy is the treatment of choice in patients with advanced or metastatic colorectal cancer (CRC) where surgical resection of metastases is not an option. Both irinotecan (IRI) and fluoropyrimidines are often included in first- or second- line chemotherapy treatment regimens in such patients. However, it is not clear whether combining these agents is superior to irinotecan alone.
OBJECTIVES
To compare the efficacy and safety of two chemotherapeutic regimens, irinotecan monotherapy or irinotecan in combination with fluoropyrimidines, for patients with advanced CRC when administered in the first or second-line settings.
SEARCH METHODS
We searched the following electronic databases to identify randomized controlled trials: Cochrane Colorectal Cancer Group Specialised Register (January 13, 2016), Cochrane Central Register of Controlled Trials (CENTRAL)(The Cochrane Library Issue 12, 2016), Ovid MEDLINE (1950 to January 13, 2016), Ovid EMBASE (1974 to January 13, 2016), registers of controlled trials in progress, references cited in relevant publications and conference proceedings in related fields (BioMed Central and Medscape's Conference). The key authors or investigators of all eligible studies, and professionals in the field were contacted when necessary. The search from January 2016 identified one eligible study, an ongoing trial currently presented as an abstract, to be considered in an update of this review.
SELECTION CRITERIA
Randomized controlled trials (RCTs) investigating the efficacy and safety of IRI chemotherapy combined with fluoropyrimidine compared with IRI alone for the treatment of patients with advanced CRC, regardless of treatment line settings.
DATA COLLECTION AND ANALYSIS
Study eligibility and methodological quality were assessed independently by the two authors, and any disagreement was solved by a third author. The data collected from the studies were reviewed qualitatively and quantitatively using the Cochrane Collaboration statistical software RevMan 5.3.
MAIN RESULTS
Five studies were included in this review with a total of 1,726 patients. The top-up search resulted in an additional ongoing trial, the results of which have not been incorporated in this review. Among five included studies, no reduction in all-cause mortality was observed in the combination arm, with a summary hazard ratio (HR) of 0.91 (95% CI: 0.81-1.02). Longer progression-free survival was observed in those treated with the combination chemotherapy (HR: 0.68, 95% CI: 0.53-0.87), however, this result may have been driven by findings from the single first-line treatment setting study.The quality of evidence for overall survival was low and for progression-free survival was moderate, mainly due to study limitation from the lack of information on randomisation methods and allocation concealment.There were higher risks of toxicity outcomes grade 3 or 4 diarrhoea and grade 1 or 2 alopecia, and a lower risk of grade 3 or 4 neutropenia in controls compared to the invervention group. Evidence for toxicity has been assessed to be low to moderate quality.
AUTHORS' CONCLUSIONS
There was no overall survival benefit of the irinotecan and fluoropyrimidine treatment over irinotecan alone, thus both regimens remain reasonable options in treating patients with advanced or metastatic CRC. Given the low and moderate quality of the evidence, future studies with sufficient numbers of patients in each treatment arms are needed to clarify the benefit observed in progression-free survival with combination irinotecan and fluoropyrimidines.

Review
INTRODUCTION
To investigate the associations of alopecia areata (AA) with serum vitamin D and calcium levels.
METHODS
A systematic review of all relevant articles published up to February 2020 in PubMed, Embase, and Cochrane Library databases was conducted. Primary endpoints were serum 25-hydroxyvitamin D [25(OH)D] levels and vitamin D deficiency, and the secondary endpoint was serum calcium level. Odds ratio (OR) and standardized mean difference (SMD) with 95% CI across studies were analyzed.
RESULTS
Data on 1585 patients with AA and 1114 controls from 16 case-control studies and three cross-sectional studies were included in this meta-analysis. A pooled meta-analysis was conducted using the random-effects model because of inter-study heterogeneity (vitamin D level, I = 87.90%; vitamin D deficiency, I = 81.10%; serum calcium level, I = 83.80%). A combined analysis revealed that patients with AA had significantly lower mean serum 25(OH)D level compared with control (WMD - 9.08, 95% CI - 11.65, - 6.50, p < 0.001), and were more likely to have vitamin D deficiency (OR 4.14, 95% CI 2.34, 7.35, p < 0.001). However, the pooled analysis revealed that patients with AA did not have significantly lower serum calcium levels compared with control (WMD - 0.17, 95% CI - 0.40, 0.06, p = 0.143). Subgroup analysis suggested that matched control, mean age, and country might contribute to the heterogeneity of serum vitamin D level, while study design, matched control, and country might contribute to the heterogeneity of vitamin D deficiency.
CONCLUSION
Deficiency of serum 25(OH)D level, rather than calcium level, was present in patients with AA. Screening for vitamin D deficiency and vitamin D supplementation may be beneficial in the treatment of patients with AA.

We performed a Bayesian network meta-analysis to indirectly compare the relative efficacy and safety of the latest JAK inhibitors for moderate-to-severe alopecia areata (AA). 13 trials totaling 3,613 patients were included. Two low-dose groups of oral formulations (ritlecitinib 10mg and ivarmacitinib 2mg) and two topical formulations (delgocitinib ointment and ruxolitinib cream) appeared to be relatively ineffective against moderate-to-severe AA. Ranking analysis suggested that brepocitinib 30mg has the best relative effect in reducing the SALT score (sucra = 0.9831), and demonstrated comparable efficacy to deuruxolitinib 12mg (sucra = 0.9245), followed by deuruxolitinib 8mg (sucra = 0.7736). Regarding the SALT response, brepocitinib 30mg ranked highest (sucra = 0.9567), followed by ritlecitinib 50mg (sucra = 0.8689) and deuruxolitinib 12mg (sucra = 0.7690). For achieving the SALT response, deuruxolitinib 12mg had the highest probability (sucra = 0.9761), followed by deuruxolitinib 8mg (sucra = 0.8678) and brepocitinib 30mg (sucra = 0.8448). Deuruxolitinib 12mg might be the most effective therapy for patients with severe AA (sucra = 0.9395), followed by ritlecitinib 50mg (sucra = 0.8753) and deuruxolitinib 8mg (sucra = 0.8070). Deuruxolitinib 12mg/8mg demonstrated notable efficacy for moderate-to-severe AA, and is expected to be a new treatment option for AA. It was worth noting that deuruxolitinib exhibit a greater likelihood of causing adverse events in comparison to other JAK inhibitors. Ritlecitinib 50mg seemed to exhibit fewer adverse effects in the high-dose groups of oral JAK inhibitors and might be an optimal choice to balance safety and efficacy. The majority of JAK inhibitors exhibited acceptable short-term safety profiles. To enhance the applicability and accuracy of our research, further head-to-head trials with longer follow-up periods are needed. identifier [CRD42022368012].

Review
PURPOSE
The purpose of this study was to evaluate the efficacy and safety of a nanodrug delivery regimen compared with conventional drug administration for the treatment of lung cancer.
MATERIALS AND METHODS
Studies were retrieved through PubMed, Web of Science, and ScienceDirect. Primary and secondary outcome measures, including overall response rate (ORR), progression-free survival (PFS), overall survival (OS), and adverse events, were extracted from the retrieved literature and systematically evaluated.
RESULTS
Six trials, including 4806 advanced non-small-cell lung cancer patients, were included in this study. Compared with conventional drug administration in the treatment of lung cancer, the nanodrug delivery regimen improved the ORR (risk ratio = 1.43, 95% confidence interval (CI) = 1.25-1.63, ≤ 0.001), prolonged PFS (hazard ratio (HR) = 0.83, 95% CI = 0.76-0.92, ≤ 0.001), and obtained superior OS (HR = 0.91, 95% CI = 0.83-0.99, ≤ 0.001). Regarding safety, the incidence of neutropenia, alopecia, sensory neuropathy, myalgia, and arthralgia was lower in the nanoadministration group, but the risk of thrombocytopenia, anaemia, and nausea was increased.
CONCLUSION
Nanodrug administration is safe and effective in patients with non-small-cell lung cancer to some extent.

Review
BACKGROUND
Ovarian cancer is the seventh most frequent cancer diagnosis worldwide, and the eighth leading cause of cancer mortality. Epithelial ovarian cancer is the most common kind, accounting for 90% of cases. First-line therapy for women with epithelial ovarian cancer consists of a combination of cytoreductive surgery and platinum and taxane-based chemotherapy. However, more than 50% of women with epithelial ovarian cancer will experience a relapse and require further chemotherapy and at some point develop resistance to platinum-based drugs. Currently, guidance on the use of most chemotherapy drugs, including taxanes, is unclear for women whose epithelial ovarian cancer has recurred. Paclitaxel, topotecan, pegylated liposomal doxorubicin hydrochloride, trabectedin and gemcitabine are all licensed for use in the UK at the discretion of clinicians, following discussion with the women as to potential adverse effects. Taxanes can be given in once-weekly regimens (at a lower dose) or three-weekly regimens (at a higher dose), which may have differences in the severity of side effects and effectiveness. As relapsed disease suggests incurable disease, it is all the more important to consider side effects and the impact of treatment schedules, as well as quality of life, and not only the life-prolonging effects of treatment.
OBJECTIVES
To assess the efficacy and toxicity of different taxane monotherapy regimens for women with recurrent epithelial ovarian, tubal or primary peritoneal cancer.
SEARCH METHODS
We searched CENTRAL, MEDLINE and Embase, up to 22 March 2022. Other related databases and trial registries were searched as well as grey literature and no additional studies were identified. A total of 1500 records were identified.
SELECTION CRITERIA
We included randomised controlled trials of taxane monotherapy for adult women diagnosed with recurrent epithelial ovarian, tubal or primary peritoneal cancer, previously treated with platinum-based chemotherapy. We included trials comparing two or more taxane monotherapy regimens. Participants could be experiencing their first recurrence of disease or any line of recurrence.
DATA COLLECTION AND ANALYSIS
Two review authors screened, independently assessed studies, and extracted data from the included studies. The clinical outcomes we examined were overall survival, response rate, progression-free survival, neurotoxicity, neutropenia, alopecia, and quality of life. We performed statistical analyses using fixed-effect and random-effects models following standard Cochrane methodology. We rated the certainty of evidence according to the GRADE approach.
MAIN RESULTS
Our literature search yielded 1500 records of 1466 studies; no additional studies were identified by searching grey literature or handsearching. We uploaded the search results into Covidence. After the exclusion of 92 duplicates, we screened titles and abstracts of 1374 records. Of these, we identified 24 studies for full-text screening. We included four parallel-group randomised controlled trials (RCTs). All trials were multicentred and conducted in a hospital setting. The studies included 981 eligible participants with recurrent epithelial ovarian cancer, tubal or primary peritoneal cancer with a median age ranging between 56 to 62 years of age. All participants had a WHO (World Health Organization) performance status of between 0 to 2. The proportion of participants with serous histology ranged between 56% to 85%. Participants included women who had platinum-sensitive (71%) and platinum-resistant (29%) relapse. Some participants were taxane pre-treated (5.6%), whilst the majority were taxane-naive (94.4%). No studies were classified as having a high risk of bias for any of the domains in the Cochrane risk of bias tool. We found that there may be little or no difference in overall survival (OS) between weekly paclitaxel and three-weekly paclitaxel, but the evidence is very uncertain (risk ratio (RR) of 0.94, 95% confidence interval (CI) 0.66 to 1.33, two studies, 263 participants, very low-certainty evidence). Similarly, there may be little or no difference in response rate (RR of 1.07, 95% CI 0.78 to 1.48, two studies, 263 participants, very low-certainty evidence) and progression-free survival (PFS) (RR of 0.83, 95% CI 0.46 to 1.52, two studies, 263 participants, very low-certainty evidence) between weekly and three-weekly paclitaxel, but the evidence is very uncertain. We found differences in the chemotherapy-associated adverse events between the weekly and three-weekly paclitaxel regimens. The weekly paclitaxel regimen may result in a reduction in neutropenia (RR 0.51, 95% 0.27 to 0.95, two studies, 260 participants, low-certainty evidence) and alopecia (RR 0.58, 95% CI 0.46 to 0.73, one study, 205 participants, low-certainty evidence). There may be little or no difference in neurotoxicity, but the evidence was very low-certainty and we cannot exclude an effect (RR 0.53, 95% CI 0.19 to 1.45, two studies, 260 participants). When examining the effect of paclitaxel dosage in the three-weekly regimen, the 250 mg/m paclitaxel regimen probably causes more neurotoxicity compared to the 175 mg/m regimen (RR 0.41, 95% CI 0.21 to 0.80, one study, 330 participants, moderate-certainty evidence). Quality-of-life data were not extractable from any of the included studies.
AUTHORS' CONCLUSIONS
Fewer people may experience neutropenia when given weekly rather than three-weekly paclitaxel (low-certainty evidence), although it may make little or no difference to the risk of developing neurotoxicity (very low-certainty evidence). This is based on the participants receiving lower doses of drug more often. However, our confidence in this result is low and the true effect may be substantially different from the estimate of the effect. Weekly paclitaxel probably reduces the risk of alopecia, although the rates in both arms were high (46% versus 79%) (low-certainty evidence). A change to weekly from three-weekly chemotherapy could be considered to reduce the likelihood of toxicity, as it may have little or no negative impact on response rate (very low-certainty evidence), PFS (very low-certainty evidence) or OS (very low-certainty evidence). Three-weekly paclitaxel, given at a dose of 175 mg/m compared to a higher dose,probably reduces the risk of neurotoxicity.We are moderately confident in this result; the true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different. A change to 175 mg/m paclitaxel (from a higher dose), if a three-weekly regimen is used, probably has little or no negative impact on PFS or OS (very low-certainty evidence).

Review
IMPORTANCE
Hair loss, or alopecia, is one of the most commonly presented problems in dermatology. Scarring alopecias are considered particularly damaging due to limited success in slowing permanent disease progression, and current treatment methods, such as intralesional and topical steroids and topical minoxidil, are largely ineffective.
OBJECTIVE
Hair transplantation is a debated treatment option for advanced cases of primary scarring alopecia. This study reviews the efficacy of hair transplantation as a treatment option for primary scarring alopecia.
EVIDENCE REVIEW
A primary literature search was conducted using PubMed to identify articles in scarring alopecia and hair transplants published from 1960 to the present time.
FINDINGS
Fifteen reports with 34 patients were included in this review. Twenty six patients experienced moderate to positive results, while 8 patients experienced negative results or recurrence of disease. Positive hair transplantation results have been reported in patients with central centrifugal cicatricial alopecia, en coup de sabre, discoid lupus erythematous, pseudopelade de brocq, and folliculitis decalvans. Positive and -negative results were observed in patients with lichen planopilaris and frontal fibrosing alopecia.
CONCLUSION AND RELEVANCE
Findings show that hair transplant surgery can be considered as a treatment option for certain primary scarring alopecias. However, data must be interpreted with caution due to concern for positive-result publication bias.
