Introduction: The cicatricial acceleration method (MAC®) promotes photobiological effects of an anti-inflammatory and healing nature. Its therapeutic radiation is emitted, producing photobiostimulant effects that result in rapid tissue repair and better tissue quality. The treatment of burns has always been a challenge, which involves both performing surgery and controlling and guiding scar regeneration, avoiding possible morbidities. Objective: To evaluate the effects of applying the MAC methodology with an AlGa (aluminum, gallium arsenide) laser on the time and quality of tissue repair in the skin of rats after induced chemical burns. Method: 22 adult male rats were subjected to a second-degree chemical burn on the back using 50% trichloroacetic acid. After the burns, the animals were randomly separated into 2 groups: control and experimental. The control group (G1) received placebo laser therapy and the laser group (G2) underwent laser irradiation with an energy density of 100 J/cm2. Histological analysis and macroscopic evaluation were carried out by means of the paper template method. Results: Group G1 showed (53%) of the necrosis area and group G2 showed (11%) necrosis area. Conclusion: The cicatricial acceleration method (MAC®) favored the repair of wounds caused by a 2nd-degree chemical burn, optimizing time and improving quality. 展开更多

Ocular cicatricial pemphigoid(OCP)is a subcategory of mucous membrane pemphigoid(MMP)where the conjunctiva is the main site of inflammation.It is a chronic and autoimmune disease characterized by acute and chronic conjunctivitis that can progress to severe conjunctival cicatrization,corneal opacification,ocular surface keratinization,and eyelid abnormalities.OCP can lead to structural damage that can result in visual impairment,visual loss,and blindness,and can have a significant impact in a patient’s quality of life.Patients may manifest with varying symptoms,degrees of severity and may have different rates of progression.Early diagnosis and appropriate systemic immunosuppression are of utmost importance for prompt and adequate disease control.Various systemic immunomodulatory therapies(IMTs),including anti-metabolites,alkylating,and biologic agents have been utilized to achieve inflammation control and remission.Careful monitoring of disease progression is important to assess response and to modify and escalate therapy if needed.Treatment to alleviate symptoms of dry eye disease and address trichiasis and other eyelid abnormalities is recommended as well.A multidisciplinary approach to optimize clinical care is recommended in the management of patients with OCP.This review will address the immunopathogenesis,clinical features,keys to diagnosis and staging of patients with OCP.It will highlight the current immunomodulators utilized for disease management and proposed stepladder strategies.This review will discuss the updated roles of combination therapy,novel use of biologics as well as the recent use of adrenocorticotropic hormone(ACTH)analog in severe recalcitrant cases. 展开更多

A 36-year-old Philippine woman presented with dark urine and yellow sclera. Endoscopic retrograde cholangiopancreatography (ERCP) confirmed dilatation of the intrahepatic bile ducts and also showed an irregular stricture of the common hepatic duct at the liver hilum. Histological examination of biopsies from the bile duct revealed epithelioid cell granulomas and caseous necrosis. Tubercle bacilli were then detected on polymerase chain reaction (PCR) testing of the bile, giving the diagnosis of biliary tuberculosis. Although microbiological cure was confirmed, the patient developed cicatricial stenosis of the hepatic duct. She underwent repeated treatments with endoscopic biliary drainage (EBD) tubes and percutaneous transhepatic biliary drainage (PTBD) tubes, and the stenosis was corrected after 6 years. We present a case of tuberculous biliary stricture, a condition that requires careful differentiation from the more common malignancies and needs long-term follow-up due to the risk of posttreatment cicatricial stenosis, although it is rare. 展开更多

Benign cicatricial airway stenosis(BCAS) is a potentially life-threatening disease.Recurrence occurs frequently after endoscopic treatment.Paclitaxel is known to prevent restenosis,but its clinical efficacy and safety is undetermined.Therefore,in this study,we investigated the efficacy and associated complications of paclitaxel as adjuvant treatment for BCAS of different etiologies.The study cohort included 28 patients with BCAS resulting from tuberculosis,intubation,tracheotomy,and other etiologies.All patients were treated at the Department of Respiratory Diseases,Beijing Tian Tan Hospital,Capital Medical University,China,between January 2010 and August 2014.After primary treatment by balloon dilation,cryotherapy,and/or high-frequency needle-knife treatment,paclitaxel was applied to the airway mucosa at the site of stenosis using a newly developed local instillation catheter.The primary outcome measures were the therapeutic efficacy of paclitaxel as adjuvant treatment,and the incidence of complications was observed as well.According to our criteria for evaluating the clinical effects on BCAS,24 of the 28 cases achieved durable remission,three cases had remission,and one case showed no remission.Thus,the durable remission rate was 85.7%,and the combined effective rate was 96.4%.No differences in outcomes were observed among the different BCAS etiologies(P=0.144),and few complications were observed.Our results indicated that paclitaxel as an adjuvant treatment has greater efficacy than previously reported BCAS treatment methods. 展开更多

AIM: To describe the clinical features and microstructural characteristics assessed by in vivo confocal microscopy(IVCM) in patients with ocular cicatricial pemphigoid(OCP).· METHODS: A descriptive, uncontrolled case series study. Patients diagnosed with OCP were examined by clinical history, slit-lamp biomicroscopy features and IVCM images. The results of direct immunofluorescence(DIF) biopsies and indirect immunofluorescence(IIF) were also recorded. Local and systemic immunosuppressive therapy were administered and adjusted according to response.·RESULTS: A total of 12 consecutive OCP patients(7male, 5 female; mean age 60.42 ±10.39y) were recruited.All patients exhibited bilateral progressive conjunctival scarring and recurrent chronic conjunctivitis was the most frequent clinical pattern. The mean duration of symptoms prior to diagnosis of OCP was 2.95 ±2.85y(range: 5mo to 10y). The Foster classification varied from stage I to IV and 20 eyes(83%) were within or greater than Foster stage Ⅲ on presentation. Two of the 12patients(17%) demonstrated positive DIF; 3 of the 12(25%) patients reported positive IIF. The mean duration of the follow-up period was 20.17 ±11.88mo(range: 6 to48mo). IVCM showed variable degrees of abnormality in the conjuctiva-cornea and conjuctival scarring was detected in all the involved eyes. Corneal stromal cell activation and dendritic cell infiltration presented asocular surface inflammation, ocular surface keratinization along with the destroyed Vogt palisades was noted in eyes with potential limbal stem cell deficiency. After treatment, remission of ocular surface inflammation was achieved in all the patients, 18 eyes(75%) remained stable, 6 eyes(25%) had recurrent conjunctivitis and cicatrization in 2 eyes(8%) was progressing.· CONCLUSION: As an autoimmune disease, OCP manifests as variable degrees of clinical and laboratory abnormalities with both local and systemic immunosuppressive treatment playing important roles in disease therapy. IVCM can be as a valuable non-invasive technique to assess ocular surface changes in a cellular level with a potential value for providing diagnostic evidence and monitoring therapeutic effects during follow-up. 展开更多

A variety of surgical techniques have traditionally been used to manage cicatricial ectropion. These techniques primarily aim at vertical lengthening of the anterior lamella and include a variety of skin flaps and grafts. Alternative techniques such as dermal filler injection to support the eyelid margin may also be used in the management of select patients with cicatricial ectropion. The application of different types of laser for scar revision throughout the body has rapidly evolved; similar mechanisms, principles and treatment rationale can be applied to the use of lasers in the management of cicatricial ectropion. Additionally, ablative lasers, such as Carbon Dioxide and Erbium:yttrium-aluminumgarnet lasers, may be used in the transdermal delivery of antifibrotic agents, such as interferon gamma, interferon alpha, vitamin D, triamcinolone and 5-fluorouracil, resulting in efficient target tissue penetration, limitation of systemic drug toxicity and decreased degradation. Although the combination of ablative fractional resurfacing and topical antifibrotic agents is a new treatment modality, there is a great potential for its efficient utilityin the management of periocular scarring and cicatricial ectropion. The introduction of these innovative therapeutic modalities offers ophthalmologists a greater range of possible effective treatments to address periocular scar tissue and the resultant cicatricial ectropion. 展开更多

Introduction:Scarring and non-scarring alopecias have rarely been described to occur together in the same patient.Distinguishing these two different types of alopecia is important as treatment and prognosis can be different.Case presentation:Here,we report the first case of simultaneous alopecia areata(AA)and central centrifugal cicatricial alopecia(CCCA)in a 35-year-old woman.New alopecic patches were noted on her frontal and vertex scalp.Biopsy of the frontal scalp revealed miniaturized hair follicles and dense lymphocytic infiltrate surrounding the hair bulbs,consistent with AA;while biopsy of the vertex scalp revealed decreased hair follicles,perifollicular fibroplasia with eccentric atrophy of the follicular epithelium,and premature desquamation of the inner root sheath at the level of the lower isthmus,consistent with CCCA.Discussion:Proposed mechanisms of these two alopecia types occurring together include loss of immune privilege,genetic predisposition,as well as unknown external factors that trigger an autoimmune lymphocytic response.Most recently,the peptidylarginine deiminase type III gene has been implicated in both diseases.Although treatment options can overlap between thetwo diseases,treatment response can differ and CCCA tendsto have a worse prognosis.Conclusion:Awareness of this concomitant presentation of two alopecic types is important for appropriate treatment and prognostication. 展开更多

Pseudopemphigoid can cause a chronic cicatricial conjunctivitis that is clinically identical to the manifestations seen in mucous membrane pemphigoid, a disorder with a common clinical phenotype and multiple autoimmune links. For the purpose of this review, we will describe pseudopemphigoid as caused by topical drugs, the most common etiology with ocular manifestations, and as caused by the pemphigus disease, a more rare etiology. Specifically, we will discuss the ophthalmological features of drug-induced cicatricial conjunctivitis, pemphigus vulgaris, and paraneoplastic pemphigus. Other etiologies of pseudopemphigoid exist that will not be described in this review including autoimmune or inflammatory conditions such as lichen planus, sarcoidosis, granulomatosis with polyangiitis(Wegener's granulomatosis), erythema multiforme(minor, major, and Stevens-Johnson syndrome), bullous pemphigoid, skin-dominated linear IgA bullous dermatosis, and skin-dominated epidermolysis bullosa acquisita. Prompt diagnosis of the underlying etiology in pseudopemphigoid is paramount to the patient's outcome as certain diseases are associated with a more severe clinical course, increased ocular involvement, and differential response to treatment. A completehistory and ocular examination may find early cicatricial changes in the conjunctiva that are important to note and evaluate to avoid progression to more severe disease manifestations. When such cicatricial changes are noted, proper diagnostic techniques are needed to help elucidate a diagnosis. Lastly, collaboration between ophthalmologists and subspecialists such as dermatologists, pathologists, immunologists, and others involved in the care of the patient is needed to ensure optimal management of disease. 展开更多

Frontal fibrosing alopecia(FFA) is a recently described form of primary cicatricial alopecia, characterized by progressive recession of the frontotemporal hairline and eyebrow loss, occurring predominantly in postmenopausal women. The incidence of FFA has increased significantly during the last decade and we may be facing an epidemic of the disease. Because this condition causes permanent hair loss, prompt diagnosis and treatment are essential for obtaining optimal outcome. This article reviews existing knowledge on epidemiology, etiopathogenesis, clinico-histological features, diagnosis,and treatment modalities of FFA. 展开更多

Background: Scarring alopecia like discoid lupus erythematosus, lichenplanopilaris and scarring folliculitis are common skin problems where differentiations between them are often difficult in many cases. Objective: To report, study and evaluate cases of lichen planopilaris and characterize the different clinical points in favor of this disease. Patients and Methods: This case series descriptive study was done at Department of Dermatology-Baghdad Teaching Hospital from January 2010 to November 2012. Sixty seven patients were included where histological and dermatological examinations were carried out to all patients regarding all relevant points related to the disease. Punch biopsies were performed from ten patients for histopathological study. Results: The mean age of onset of the disease was 36.7 ± 5 years with a mean duration of the disease being 4.4 ± 3 years. The male to female ratio was 1.4:1. The characteristic lesions were pigmented scarring moth eaten alopecia surrounded by pigmented hyperkeratotic follicular papules involving mainly the fronto-vertical and parietal scalp. Conclusions: Lichen planopilaris is a common cause of scalp scarring alopecia in adult and it has many characteristic clinical features which can facilitate differentiation from other pathologic scalp conditions like discoid lupus erythematosus. 展开更多
