[Utilidad del complejo soluble de ataque a membrana para determinar actividad clínica de la dermatomiositis y respuesta al tratamiento].

Introduction: Dermatomyositis is an autoimmune disease and the most common idiopathic inflammatory myopathy. During patient follow-up, determining biochemical parameters is required in order to assess for disease activity and treatment efficacy.

Objective: To determine the relationship between the degree of activation of the complement system through the soluble membrane attack complex (c5b-9), dermatomyositis clinical activity and its variations with conventional treatment.

Evidence-based treatment for gynoid lipodystrophy: A review of the recent literature.

Gynoid lipodystrophy (GLD) is a structural, inflammatory, and biochemical disorder of the subcutaneous tissue causing alterations in the topography of the skin. Commonly known as "cellulite," GLD affects up to 90% of women, practically in all stages of the life cycle, beginning in puberty. It is a clinical condition that considerably affects the patients' quality of life.

[Dermatologists happiness and satisfaction].

Objective: To assess the level of happiness and satisfaction in the life and medical practice of dermatologists in Mexico.

Method: A descriptive study (online survey) was conducted focused on practicing dermatologists in our country. Questions included demographic characteristics, the Pemberton happiness index (with local validation) and questions that assessed the degree of personal satisfaction.

[Crusted scabies in HIV/AIDS infected patients. Report of 15 cases].

Background: Crusted (Norwegian) scabies is a rare disease that occurs in patients with compromised immune system like patients with HIV/AIDS. We report 15 cases of crusted scabies in patients with HIV/AIDS successfully treated with oral ivermectin.

Clinical Cases: The mean age of the patients was 43.

Congenital Malalignment of the Great Toenail.

Congenital malalignment of the great toenail (CMA) is a disorder of the anatomic orientation of the ungual apparatus, in which the longitudinal axis of the nail plate is not parallel with the axis of the distal phalanx but is deflected sideways. This disorder is understood to arise from multiple factors. Although many theories have been proposed about its origin, its pathogenesis is not fully known.

[Bacterial resistance in acne? A meta-analysis of the controversy].

Background: Acne is one of the dermatological pathologies with the highest incidence around the world. It is a multifactorial disease and its treatment can be complex. Propionibacterium acnes play a key role in the inflammation of this dermatosis.

Efficacy and safety of adapalene gel 0.1% and 0.3% and tretinoin gel 0.05% for acne vulgaris: results of a single-center, randomized, double-blinded, placebo-controlled clinical trial on Mexican patients (skin type III-IV).

Background: The efficacy of topical retinoids is well known according to several clinical studies conducted predominantly among Caucasian patients. This study aimed to evaluate the efficacy and safety profile of adapalene and tretinoin among Mexican patients.

Aims: To compare adapalene 0.

Th-17 and the lack of efficacy of ustekinumab in pemphigus vulgaris.

Systemic corticosteroids represent an effective treatment for pemphigus vulgaris (PV). However, this treatment is related to many adverse side effects. Herein, we report a case of PV treated with ustekinumab.

The efficacy and safety of sertaconazole cream (2 %) in diaper dermatitis candidiasis.

Aim: Diaper dermatitis (DD) is an inflammatory irritating condition that is common in infants. Most cases are associated with the yeast colonization of Candida or diaper dermatitis candidiasis (DDC), and therefore, the signs and symptoms improve with antimycotic treatment. Sertaconazole is a broad-spectrum third-generation imidazole derivative that is effective and safe for the treatment for superficial mycoses, such as tineas, candidiasis, and pityriasis versicolor.

Preliminary study of the efficacy and tolerability of combination therapy with calcipotriene ointment 0.005% and tacrolimus ointment 0.1% in the treatment of stable plaque psoriasis.

Calcipotriene ointment is widely used in the topical treatment of psoriasis, with tacrolimus ointment as an effective alternative in controlling stable plaque psoriasis. The efficacy of the combination of both products on stable plaque psoriasis has not been assessed in the literature consulted. We evaluated the efficacy of calcipotriene ointment 0.

Comparison of direct microscopy, culture and calcofluor white for the diagnosis of onychomycosis.

Background: Mycological diagnosis of onychomycosis can be performed by direct microcopy (KOH), cultures and calcofluor white.

Aims: To compare the percentage of positivity and the degree of correlation of KOH, cultures and calcofluor white for the diagnosis of onychomycosis.

Methods: Descriptive, transversal and comparative study.

Cutaneous zygomycosis.

Cutaneous zygomycosis is a fungal infection caused by zygomycetes that affects the skin. It occurs in uncontrolled diabetic patients and immunosuppressed individuals. It has 2 clinical forms: primary cutaneous zygomycosis and secondary cutaneous zygomycosis.

Acetylcholine receptor antibodies in patients with pemphigus vulgaris: correlation with disease extent at the time of diagnosis and during follow-up.

Several studies have tried to determine the relationship between autoantibodies against the acetylcholine receptor and the development of pemphigus vulgaris. In this study, we observed that antibody levels against the acetylcholine receptor are mildly elevated in pemphigus vulgaris (PV), and significantly correlate with disease severity on the initial diagnosis and during follow up. However, it is not clear if these antibodies are just an epiphenomenon or a potential trigger of the known pathogenic process in PV.

Serum lactate is a useful predictor of death in severe sepsis in patients with pemphigus vulgaris.

Background: Serum lactate is a useful prognostic marker in severe sepsis; high levels of serum lactate in critically ill patients are related to high mortality risk; assessing serum lactate levels in patients with pemphigus vulgaris is justified. The objective was to determine the role of serum lactate as a predictor of shock and its outcome in patients with pemphigus vulgaris and severe sepsis without acute organ dysfunction.

Methods: Thirty-seven patients with pemphigus vulgaris, 22 with severe sepsis and 15 without sepsis.

[Skin cancer in adults younger than 40 years at the General Hospital of Mexico].

Skin cancer is the most common malignant neoplasm reported worldwide. Over the last 20 years, skin cancer has been recognized in a high proportion among young people not associated with genetic disorders or other diseases. In Mexico there is no epidemiological information about this topic, so we made a retrospective study from 2006 to 2009 in the Dermatology service of the General Hospital of Mexico.

Efficacy of dioic acid compared with hydroquinone in the treatment of melasma.

Background: Melasma is a common disorder of pigmentation characterized by relatively symmetric, brown or gray-brown patches on sun-exposed facial areas. Hydroquinone, the most effective agent in melasma, is known to irritate the skin, and so new alternatives in the treatment of melasma are required. We sought to assess the clinical response of a new depigmenting agent in melasma.

Efficacy and tolerance of superoxidized solution in the treatment of mild to moderate inflammatory acne. A double-blinded, placebo-controlled, parallel-group, randomized, clinical trial.

Introduction: Superoxidized solution (SOS) is an electrochemically processed aqueous solution manufactured from pure water and sodium chloride. Inflammatory skin disorders have all improved their outcomes with the use of SOS. These indications suggest that SOS could be useful in acne.
