A Retrospective Study on Alopecia Areata in Children: Clinical Characteristics and Treatment Choices. Skin Appendage Disord 2021; 7:454-459. [PMID: 34901176 DOI: 10.1159/000518042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Accepted: 06/21/2021] [Indexed: 11/19/2022] Open
Abstract
Background Although children are affected frequently with alopecia areata (AA), data are limited on clinical characteristics and treatment choices. Materials and Methods We retrospectively reviewed the records of the pediatric dermatology department over a 12-year period to identify children with AA. Clinical data were collected. Results Three hundred and sixty-four children with AA were identified, aged 1-12 years, 214 males and 150 females. The mean age of onset was 6.6 years (±3.3). The disease presented with patches on the scalp in the majority (90.7%), whereas only 6 children had alopecia totalis or universalis. The most commonly prescribed treatment was topical steroids (69.1%), followed by the combination of topical steroids and minoxidil 2% (14.3%). Oral steroids were prescribed in only 16 children. Follow-up at 3 months was available for only 70 children and the majority (84.3%) had some hair regrowth. Hair regrowth was unrelated to the number of plaques (p = 0.257), disease location (p = 0.302), and atopy (p = 0.999). Hair regrowth only correlated with the type of treatment (p = 0.003) with potent topical and intralesional steroids giving the best results. Conclusion AA usually presents with a mild form in children, and potent topical steroids are the mainstay of treatment.

Abstract
A female patient with xeroderma pigmentosum and multiple basal cell carcinomas was treated with a hedgehog pathway inhibitor (vismodegib), which successfully treated the majority of her basal cell carcinomas while preventing the appearance of new lesions. The sum diameter of lesions showed a 61% decrease after 16.5 months of treatment, although after 18.5 months of treatment, a persistent lesion showed progression and metatypical characteristics; adverse events included persistent alopecia muscle cramps, dysgeusia, and amenorrhea. Despite these limitations, vismodegib may have a role in the treatment of some patients with xeroderma pigmentosum.

Abstract
Background Bullous pemphigoid (BP) is a chronic, autoimmune blistering skin disease that
affects patients' daily life and psychosocial well-being. Objective The aim of the study was to evaluate the quality of life, anxiety, depression
and loneliness in BP patients. Methods Fifty-seven BP patients and fifty-seven healthy controls were recruited for
the study. The quality of life of each patient was assessed using the
Dermatology Life Quality Index (DLQI) scale. Moreover, they were evaluated
for anxiety and depression according to the Hospital Anxiety Depression
Scale (HADS-scale), while loneliness was measured through the Loneliness
Scale-Version 3 (UCLA) scale. Results The mean DLQI score was 9.45±3.34. Statistically significant
differences on the HADS total scale and in HADS-depression subscale (p=0.015
and p=0.002, respectively) were documented. No statistically significant
difference was found between the two groups on the HADS-anxiety subscale.
Furthermore, significantly higher scores were recorded on the UCLA Scale
compared with healthy volunteers (p=0.003). Conclusion BP had a significant impact on quality of life and the psychological status
of patients, probably due to the appearance of unattractive lesions on the
skin, functional problems and disease chronicity.

Abstract
Paediatric melanoma, although rare, is the most common skin cancer in children. Our current knowledge on paediatric melanoma incidence trends is expanding, as several studies have addressed this issue with conflicting results. Known risk factors for paediatric melanoma include family history of melanoma, a previous history of malignancy, large congenital nevi, numerous melanocytic nevi, sunburns, increased UV exposure and a sun-sensitive phenotype. In younger children, melanoma more often presents with atypical features, such as a changing, amelanotic or uniformly coloured, often bleeding lesion, not fulfilling in most cases the conventional ABCDE criteria. The major differential diagnoses are melanocytic nevi, proliferative nodules in congenital nevi and atypical Spitz tumours. Moreover, in the younger age group non-Caucasian children are over-represented, tumours tend to be thicker and lymph nodes are often involved. Despite the frequent diagnosis at an advanced stage, the overall survival is fair in paediatric melanoma. Specific guidelines for management of melanoma in children do not exist, and most often the disease is treated similarly to melanoma in adults.

Quality of life and psychosocial aspects in Greek patients with psoriasis: a cross-sectional study. An Bras Dermatol 2016; 90:841-5. [PMID: 26734865 PMCID: PMC4689072 DOI: 10.1590/abd1806-4841.20154147] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2014] [Accepted: 01/14/2015] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Psoriasis is a common, long-term skin disease associated with high
levels of psychological distress and a considerable adverse impact on
life. The effects of psoriasis, beyond skin affliction, are seldom
recognized and often undertreated. OBJECTIVE The aim of the study is to evaluate the quality of life, anxiety and
depression, self-esteem and loneliness in patients with psoriasis. METHODS Eighty-four patients with psoriasis were enrolled in the study. The
quality of life, depression and anxiety, loneliness and self-esteem of
the patient were assessed using the Dermatology Life Quality Index,
Hospital Anxiety and Depression Scale, the UCLA loneliness Scale
(UCLA-Version 3) and Rosenberg's Self-esteem Scale, respectively. RESULTS The Dermatology Quality of Life Index score among psoriasis patients was
12.61 ± 4.88. They had statistically significantly higher
scores according to the Hospital Anxiety and Depression Scale -anxiety
subscale (p=0.032)-compared with healthy volunteers. Moreover, a
statistically significant difference was found between the two groups
concerning the UCLA-scale (p=0.033) and RSES-scale (p<0.0001).
Female patients presented with lower self-esteem than male
patients. CONCLUSION Psoriasis is a distressing, recurrent disorder that significantly
impairs quality of life. Therefore, the recognition and future
management of psoriasis may require the involvement of
multi-disciplinary teams to manage the physical, psychological and
social aspects of the condition, as is the case for systemic,
long-term conditions.

Abstract
The main objective in the treatment of pemphigus vulgaris is to control the disease, prevent relapses, and avoid adverse events associated with the prolonged use of steroids and immunosuppressive agents. Systemic corticosteroids remain the gold standard treatment for pemphigus vulgaris. Azathioprine and mycophenolate mofetil are the first line of steroid-sparing treatment. Rituximab is extremely effective in recalcitrant pemphigus, when other treatments fail to control the disease. The European Dermatology Forum recommends tapering prednisolone by 25% every 2 weeks after the consolidation phase, and a 5 mg reduction every 4 weeks when the dose is reduced to <20 mg. If the patient relapses, options include increasing steroids back to the previous dose, adding an immunosuppressant if using steroid monotherapy, or replacing a first-line immunosuppressant by another if already on combination therapy.

Abstract
Primary hyperhidrosis, although extensively documented in adults, typically has onset that dates back to early childhood. It is an unpleasant and socially disabling problem for the affected child, but little attention has been paid to the disease in adolescents. The objective of the current study was to evaluate the effectiveness of botulinum toxin type A (BTXA) in adolescents with primary palmar and axillary hyperhidrosis and to determine its effect on quality of life and social isolation. Thirty-five individuals (17 girls, 18 boys) with moderate to severe palmar and axillary hyperhidrosis were treated with BTXA (onabotulinum). Patients were examined at baseline and 6 months after treatment. The Hyperhidrosis Disease Severity Scale (HDSS) was used to evaluate disease severity and the Children's Dermatology Life Quality Index (CDLQI) was used to assess quality of life. The University of California at Los Angeles loneliness scale (UCLA version 3) was used to assess personal perception of loneliness and social isolation. The median age of the participants was 14 years, and 48.6% were female. Twenty-one had palmar hyperhidrosis, and 14 had axillary hyperhidrosis. Total CDLQI and social isolation scores decreased significantly after treatment with BTXA (both p < 0.001). There was a significant difference between pre- and post-treatment levels of severity of hyperhidrosis. No statistically significant difference was documented for CDLQI and UCLA scores between boys and girls. Treatment of hyperhidrosis with BTXA resulted in improvement in quality of life, social skills, and activities.

Abstract
BACKGROUND Epidemiological data on primary syphilis in Greece are limited. OBJECTIVE The purpose of the present study was to investigate the trends of the disease in Greece during the last few years and whether they are in accordance with the trends in other European countries and the United States of America. METHODS We conducted a retrospective analysis based on records of patients who visited the Sexually Transmitted Infections Unit of 'A. Sygros' Hospital in Athens, Greece, during the period 2005-2012. Our hospital is a tertiary referral centre for sexually transmitted infections covering an area of more than four million people, which is almost half the population of Greece. We documented the total annual number of patients, the male to female ratio, sexual orientation, patients' ethnic origin and education level. RESULTS We reviewed the records of 1185 patients with a confirmed diagnosis of primary syphilis. The total number of patients with primary syphilis has risen from 111 in 2005 to 158 in 2012, an increase of 42.3%. The mean annual number is 148. The mean male to female ratio is 4.76 : 1, with a peak value of 8.50 : 1 in 2011. The majority of patients are of Greek origin, ranging from 67.4% to 87.2%. Within the male patients group, it seems that the percentage of men having sex with men has risen steadily from 2005 (20.7%) up to 2010 (59.1%) with a decline in 2012 (46.0%). The mean value over 8 years is 45.0%. CONCLUSION Primary syphilis in Greece is on the rise. Τhe majority of our patients are Greek, despite immigrant influx. Men clearly outnumber women, representing more than 80% of the total number of patients. Furthermore, there seems to be a trend towards predominance of men having sex with men as the core group among male patients.

Abstract
INTRODUCTION All available treatments for anogenital warts have substantial failure rates. An immunomodulating treatment that enhances the patient's own immunity could be valuable as an adjuvant to conventional methods. METHODS About 123 patients were enrolled in this study and were randomized either to undergo only cryotherapy every 3 weeks (n = 60 patients) or to undergo cryotherapy and to receive a mixture containing 20 mg sterol and 0.2 mg sterolin (BSS-BSSG mixture), known for its immunomodulating properties (n = 63). RESULTS A complete response after 3 months was demonstrated by 18.3% of the patients in the first group and 30.2% of the second group, while 61.7% of the first group and 79.4% of the second group were lesion free at the end of the 6-month follow-up period. Cox regression analysis of the time until response showed a significant advantage to the mixture treatment group (hazard ratio 2.76, 95% confidence interval 1.61-5.67). LIMITATIONS The study was not placebo controlled. CONCLUSION The BSS-BSSG mixture gave promising results as an adjuvant to cryotherapy and may be used in patients with refractory warts.

Abstract
INTRODUCTION The health-related quality-of-life (HRQoL) instruments are an important tool for the evaluation of medical outcomes. Sexually transmitted diseases (STDs) influence the patients' life. We aimed to evaluate the HRQoL in patients with anogenital warts at the time of and 1 month after the diagnosis. MATERIALS AND METHODS We used the short-form (SF)-36 questionnaire to compare the HRQoL of 91 patients with anogenital warts to 53 control subjects with the same socioeconomic characteristics. RESULTS There was no statistical difference in the overall HRQoL measurement between the anogenital wart patients and controls. However, there was an improvement in the scales of vitality (65.22 ± 15.70 vs. 69.04 ± 14.11, respectively; p < 0.05) and mental health (65.00 ± 20.09 vs. 69.43 ± 18.08, respectively; p < 0.05) in anogenital warts patients between the time of diagnosis and 1 month later. Furthermore, there was a significant deterioration in the scale of social functioning (73.47 ± 22.18 vs. 72.89 ± 19.28, respectively; p < 0.05). The small sample size is a limitation of our study. CONCLUSIONS HRQoL does not appear to be influenced in anogenital wart patients, as measured by the generic instrument SF-36. It is therefore important to develop specific instruments for the measurement of HRQoL in this group of patients.

Abstract
The factors predicting an unfavourable response of genital warts to treatment have not been determined. The disease characteristics were recorded for 390 patients with genital warts and treated by cryotherapy. The time to achieve clearance was recorded. A personal and family history of asthma, hay fever or eczema, as well as a personal history of common warts and number of recurrences was obtained by telephone four to five years after the clinical visits. In multiple regression analysis, the number of lesions (P < 0.001), extent of the disease (P = 0.003) and personal history of atopy (P = 0.001) were found to influence the time until response to treatment. Similar results were obtained for family history of atopy. The number of sexual partners (P = 0.007), extent of the disease (P = 0.009) and personal history of atopy (P < 0.001) were the main factors influencing the probability of recurrence in multiple logistic regression. The results for family history of atopy were again similar. The study concludes that atopy is a major factor influencing the time frame of the therapeutic response and the probability of recurrence in patients with genital warts.

Abstract
A large number of different substances comprise the family of retinoids, which are traditionally described as vitamin A derivatives. By exerting their action through nuclear and cytoplasmic receptors they may improve photoaging. Tretinoin is the best studied retinoid in the treatment of photoaging. Others such as isotretinoin, retinaldehyde, and tazarotene, although less well studied, have given promising results.

Abstract
INTRODUCTION Pityriasis rubra pilaris is an uncommon inflammatory and hyperproliferative dermatosis of juvenile or adult onset. The etiology of the disease is still unknown. CASE PRESENTATION We present the cases of two Caucasian men aged 53 and 48 who presented with pityriasis rubra pillaris type 1; both patients also exhibited an abnormal immunological profile. CONCLUSION Pityriasis rubra pillaris is currently classified as a keratinization disorder. The abnormal immunological profile reported in our patients along with the comorbidity of pityriasis rubra pilaris with autoimmune disorders reported in the literature poses the question of a possible pathogenetic role for the immune response in this disorder.

Abstract
Summary The aim of this study was to compare the efficacy of crotherapy versus imiquimod 5% in the treatment of anogenital warts. Eighty HIV-negative males were included in the analysis; 35 of them were treated with imiquimod 5% three times a week for 6–10 hours and 45 of them with cryotherapy once in three weeks. Follow-up appointments were arranged every month for the first three months and then at six and 12 months, or in between whenever the patients noticed any signs of recurrence. Treatment for both groups was continued for a total of 12 weeks or until the warts cleared. At the end of three months, irrespective of the type of treatment, 78.8% of the patients demonstrated 100% improvement. Cryotherapy was more effective, as 86.7% of patients showed 100% improvement compared with 68.6% of patients in the imiquimod group. On the contrary, 17.1% of the imiquimod group did not show any signs of improvement, compared with 2.2% of the cryotherapy group ( P = 0.017). However, patients treated with imiquimod tended to improve earlier than patients on cryotherapy ( P = 0.012). No statistically significant difference was observed regarding the recurrence rate between the two groups ( P = 0.138). Treatment with imiquimod was less painful than cryotherapy ( P = 0.034). Cryotherapy was more effective than imiquimod 5% for the treatment of anogenital warts in males but was more inconvenient.

Abstract
In general, steroid hormones exert their effects through intracellular receptors, the glucocorticoid (GR), mineralocorticoid (MR), androgen (AR), estrogen (ER), and progesterone (PR) receptors. In this brief review, we will focus on glucocorticoid and sex hormone actions in the skin through their distinct receptors and discuss their clinical relevance.

Abstract
Our purpose was to investigate the human papillomavirus (HPV) type distribution using the Hybrid Capture 2 (HC2) Microplate assay in males. We tested a urethral swab from 550 HIV-negative males with genital warts and 64 HIV-negative males clinically free of genital warts, partners of HPV-infected females, using the HC2 Microplate assay. A perianal swab was also obtained from patients with perianal warts. In the first group, HPV DNA of any type was detected in 280 (50.9%) patients. Relatively few patients with urethral or perianal warts demonstrated a negative test (both P < 0.0001). Low-risk types were commoner, accounting for 60.0% of the HPV cases, high/intermediate-risk types accounted for 23.6%, while 46 men (16.4%) were infected with both types. Of 13 subjects (20.3%) of the second group who tested positive for HPV DNA, 61.5% were infected by low-risk types, 23.1% by high/intermediate-risk types and 15.4% had a dual infection. In conclusion, male partners of infected females and males with genital warts are predominantly infected by low-risk HPV types, but a substantial proportion is also or only affected by high-risk types.

Abstract
BACKGROUND The aim of this study was to investigate the histological and immunohistochemical features of granuloma annulare (GA) in comparison to deep granuloma annulare (DGA) and granulomatous dermatoses (GDs). METHODS Our material comprised 13 GA, 8 DGA and 1 atypical granuloma annulare (AGA) in a child with primary immunodeficiency, 10 cases of nonspecific GDs and 1 case of sarcoidosis with cutaneous involvement. The immunohistochemical streptavidin-biotin-Horseradish peroxidase (HRP) analysis was performed on paraffin sections for the detection of CD68/KP-1, CD68/anti-human CD68 clone PGM1 (PGM1), lysozyme, S-100 protein, CD1a, CD3, CD20/L-26, CD4 and CD8. RESULTS All 13 GA were characterized by typical palisading and interstitial granulomas. In 6 cases, the lesion extended to the subcutaneous fat, while a considerable perivascular lymphocytic infiltrate without any signs of vasculitis was observed in 10 cases. The DGA were located to the deep dermis and subcutaneous fat, showing palisading granulomas with central necrobiosis. Immunohistochemistry revealed a broad intense expression of CD68/PGM1 in the histiocytic population in all cases, a constant but fainter detection of CD68/KP-1 and a variable one of lysozyme. T-cell markers (CD3, CD4 and CD8) were mainly detected in the perivascular lymphocytic infiltrate of GA and DGA, with CD4+ T lymphocytes predominating over CD8+ in GA and DGA, while CD8+ T lymphocytes was the predominant population in AGA. CONCLUSIONS CD68/PGM1 is a sensitive and reliable histiocytic marker in confirming the histiocytic nature of equivocal GA and DGA, but the histiocytic immunoprofile is of no particular usefulness in differentiating GA from other GD.

Cell cycle and apoptosis regulators in Spitz nevi: comparison with melanomas and common nevi. J Am Acad Dermatol 2007; 56:815-24. [PMID: 17437889 DOI: 10.1016/j.jaad.2006.09.015] [Citation(s) in RCA: 32] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2006] [Revised: 09/11/2006] [Accepted: 09/14/2006] [Indexed: 11/21/2022]
Abstract
BACKGROUND Deregulated cell cycle control is one of the hallmarks of tumor development. The expression of different cell cycle regulators has been used in various neoplasms as an adjunct to diagnosis. OBJECTIVE We sough to determine the expression of cell cycle and apoptosis regulators in Spitz nevi and to appraise its value as a diagnostic adjunct in the differential diagnosis from melanomas and common nevi. METHODS Ki-67, p-27, p-16, p-53, p-21, Rb, cyclin D1, cyclin A, cyclin B1, bcl-2, and bax expression was assessed by immunohistochemistry in 10 Spitz nevi and was compared with 16 melanomas and 20 common nevi immunohistochemical expression. RESULTS P-27 (60% +/- 20.13), p-16 (62.00% +/- 10.85), and bcl-2 (46.00% +/- 42.47) were highly expressed in Spitz nevi, whereas Ki-67 (2.80% +/- 2.55), Rb (3.75% +/- 4.55), p-53 (2.30% +/- 0.10), cyclin A (0.70% +/- 1.56), B1 (0.20% +/- 0.34), and bax (2.65% +/- 6.37) demonstrated a limited expression. Cyclin D1 (8.60% +/- 7.30) and p-21 (6.40% +/- 5.37) showed a moderate expression. The expression of bax (P = .001), Ki-67 (P < .0001), Rb (P < .0001), p-16 (P < .0001), cyclin A (P < .0001), and cyclin B1 (P < .0001) was significantly higher in melanomas in comparison with Spitz nevi, whereas p-27 expression was significantly higher in Spitz nevi (P < .0001). A trend for significant difference in favor of melanomas was also observed for p-53 (P = .002). On the other hand, no difference was detected for bcl-2 (P = .275), p-21 (P = .055), or cyclin D1 (P = .077). Spitz nevi demonstrated a trend for a higher expression for p-21 (P = .008) and cyclin D1 (P = .006), whereas they exhibited lower p-16 (P = .004) in comparison with common nevi. LIMITATIONS The number of Spitz nevi was relatively small. CONCLUSION Spitz nevi differ from melanomas in their immunohistochemical pattern of expression of cell cycle and apoptosis regulators and more closely resemble common benign nevi.

Abstract
BACKGROUND Narrowband UVB (NB-UVB) phototherapy is considered an accepted therapy for vitiligo. OBJECTIVE We sought to estimate the effectiveness of NB-UVB in patients with vitiligo, identify predictive factors of response, and assess the stability of NB-UVB-induced repigmentation. METHODS In all, 70 patients with vitiligo were treated twice weekly with NB-UVB. RESULTS Cosmetically acceptable (>75%) repigmentation was achieved in 34.4% of patients with lesions on the face and in 7.4% of patients with lesions on the body. Patients with phototypes III to V had a greater chance to achieve greater than 75% repigmentation on the face. Patients who responded in the first month of treatment were more likely to achieve better repigmentation rates. Repigmentation was stable in 14.3% of patients 4 years after cessation of treatment. LIMITATIONS The study was uncontrolled. Treatment frequency was twice weekly. These results may not be representative of different treatment regimens. CONCLUSION Patients with vitiligo who have lesions on the face, darker phototypes, and early response to treatment have a greater chance to achieve satisfactory repigmentation after NB-UVB phototherapy.

Abstract
Although many skin conditions are amenable to treatment, on certain occasions dermatology and plastic surgery have not much to offer and patients are left with disfigurements. Cosmetic camouflage is a therapy that has been developed to alleviate the suffering of those who have been disfigured by a congenital or an acquired lesion and who have no other choice than living with their deformity.

Abstract
Ultraviolet sun radiation can cause several deleterious effects on the skin, including photoaging and carcinogenesis. Physical protection and sunscreens are currently the two main types of photoprotection. Overall, people seem informed about the dangers of sun exposure, but sometimes they are not willing to implement the right sun-protection measures. Sunscreens are reported to be the most frequently used method worldwide, but they cannot substitute physical protection and a proportion of people do not apply them correctly. Public campaigns, together with fashion and the right role models, can still offer a lot in persuading people to change their habits towards a more sun-protected life.

Abstract
Tinea capitis as a result of Trichophyton rubrum has very rarely been reported in infants. A 3-month-old girl with tinea capitis as a result of T. rubrum is reported. Our patient was treated with a 3-week course of oral fluconazole, which resulted in clearance of the scalp lesion. To our knowledge this case is the first in the literature in which fluconazole was used to treat T. rubrum tinea capitis in children.

Abstract
BACKGROUND Melanocytes represent a static component of the epidermis, and the role of apoptosis in basal melanocyte function and melanocytic tumour formation has not been fully elucidated. OBJECTIVES The aim of this study was to investigate the expression of Bcl-2 anti-apoptotic and Bax apoptotic proteins in congenital naevi in correlation with p-27 protein and Ki-67 proliferative index. METHODS Our material comprised 30 congenital naevi (eight giant) excised from children aged from 15 days to 14 years old. The immunohistochemical streptavidin-biotin method was performed on paraffin sections for the detection of Bcl-2 (cl100/D5), Bax (cl2D2) , Ki-67 (MIB-1) and p-27 (1B4) proteins with monoclonal antibodies. RESULTS Bcl-2 protein was detected in all cases showing a strong diffuse cytoplasmic expression in >70% of the naevocytes and was preserved in the deeper parts of the naevi. On the other hand, Bax was detected in 13 of the cases, showing a fainter cytoplasmic expression in 40-50% of the naevocytes without any particular topographic distribution. Ki-67 was detected in all cases showing a limited expression in 1-2% of the nuclei mainly in the junctional and upper dermal components. p-27 protein showed a broad diffuse nuclear expression (>70% of the nuclei) in all cases with a particular increase in the deeper parts of the naevi. Bcl-2 expression showed a parallel correlation with p-27 protein. CONCLUSIONS Broad Bcl-2 expression in congenital naevi suggests that suppression of apoptosis may play an important role in the maintenance of naevocytes despite the low proliferative activity.

Abstract
BACKGROUND The treatment of keloids remains unsatisfactory. Intralesional 5-fluorouracil (FU) has not been much investigated as a monotherapy in the treatment of keloids. OBJECTIVE We sought to evaluate the use of intralesional injections of 5-FU in the treatment of keloids. METHODS A total of 20 patients (11 male and 9 female) were treated once weekly with intralesional injections of 5-FU (50 mg/mL). Patients received an average of 7 treatments. Average injection volumes were 0.2 to 0.4 mL/cm2. All patients had full blood cell count, liver function tests, and renal function tests before and after treatment was commenced. A total of 10 patients had biopsy specimens taken before starting treatment as a baseline and after 6 sessions. Routine hematoxylin-eosin and immunohistochemical analysis detecting Ki-67 and transforming growth factor-beta were performed on paraffin sections. All patients were followed up for 12 months, or until recurrence was noted. RESULTS Of 20 patients, 17 (85%) showed more than 50% improvement. Only one did not respond favorably. Small and previously untreated lesions improved the most. Pain (20 of 20), hyperpigmentation (20 of 20), and tissue sloughing (6 of 20) were the main adverse effects. Histopathologic and immunohistochemical evaluation were consistent with the clinical observations. Ki-67 proliferative index was significantly reduced (P = .0001) after treatment. Transforming growth factor-beta was reduced less significantly. Recurrence was noted in 47% (9 of 19) of patients who responded to treatment within 1 year. A correlation was found ( P = .028) between the duration of the lesions and recurrence. CONCLUSION Our study demonstrates that intralesional 5-FU may be effective in the treatment of keloids, but recurrence is common and further investigation is required.
