Blistering and aggressive paniculite cutaneous T-cell lymphoma.

Background: Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is characterized by atypical T-cells expressing the α/β T-cell receptor in the subcutaneous fat. Although it is usually indolent, some cases can show an aggressive course. It is usually a disease of the middle-aged, but can rarely affect children.

Limited granulomatosis with polyangiitis in children with idiopathic orbital inflammation: a case series and literature review.

Idiopathic orbital inflammation (IOI) is a diagnosis of exclusion, but the exclusion of other inflammatory diseases of the orbit is broad and relies on clinician experience, response to corticosteroid, or biopsy. This study aimed to investigate the presence of granulomatosis with polyangiitis (GPA) in patients initially diagnosed as IOI and describe its clinicopathological features, ANCA status, treatment, and outcome. We performed a retrospective case series study of children diagnosed with limited GPA (L-GPA) in patients with IOI.

Acute lichenoid and varioliform pityriasis in a pediatric patient.

Background: Pityriasis lichenoides et varioliformis acuta (PLEVA) is a rare dermatosis recognized as a benign condition of unknown etiopathogenesis. It is more common in pediatric patients and young adults and is characterized by multiple small or large erythematous plaques spread over the trunk and extremities.

Case Report: We describe the case of a 5-year-old male, previously healthy, with multiple erythematous lesions that disappeared leaving hypopigmented macules.

Dysferlinopathy misdiagnosed with juvenile polymyositis in the pre-symptomatic stage of hyperCKemia: a case report and literature review.

Background: Dysferlinopathy encompasses a group of rare muscular dystrophies caused by recessive mutations in the DYSF gene. The phenotype ranges from asymptomatic elevated serum creatine kinase (hyperCKemia) to selective and progressive involvement of the proximal and/or distal muscles of the limbs. Bohan and Peter criteria are the most widely used for the diagnosis of polymyositis, but they have limitations and can misclassify muscular dystrophies with inflammation as polymyositis.

Tumorous congenital calcinosis cutis associated with early childhood epileptic encephalopathy with a pathogenic FGF12 gene variant.

Background: Calcinosis cutis is the deposit of insoluble calcium salts in the skin. It is classified according to its pathogenesis in dystrophic, metastatic, idiopathic, iatrogenic, and calciphylaxis. Idiopathic calcinosis is asymptomatic, occurs in healthy patients, and includes scrotal calcinosis, Winer's nodular calcinosis or subepidermal calcified nodules, and familial tumor calcinosis.

Acquired dermal melanocytosis on the hand of a pediatric patient.

Background: Dermal melanocytosis is a group of pigmentary dermatological diseases associated with melanocytic proliferation, which are classified based on their number and depth at the level of the dermis; they may be congenital or acquired.

Case Report: An 11-year-old male patient with no history of importance for the current condition started 5 years ago with a dark macula in the left hand palm, which was asymptomatic but grew gradually. On physical examination, dermatoses affecting the left palm, palmar face of proximal phalanges of the third, fourth and fifth fingers, characterized by the presence of blackish greyish macula, diffuse and irregular edges, not infiltrated or indurated were detected.

Additional compounds and the therapeutic potential of Cnidoscolus chayamansa (McVaugh) against hepatotoxicity induced by antitubercular drugs.

Previously non-isolated compounds (scopoletin and β-D-Glucopyranoside, (1R)-O-isopropyl 6-O-(2,3,4-tri-O-acetyl-β-D-xylopyranosyl)-2,3,4-triacetate) were isolated from an organic extract of the Cnidoscolus chayamansa stem. Also, lupeol acetate (main compound, 49.7 mg/g of dry extract) and scopoletin (0.

Hepatoprotective and Anti-Inflammatory Activities of the (Mc Vaugh) Leaf Extract in Chronic Models.

Previous report described that CHCl:MeOH extract of leaves and pure compounds (moretenol, moretenyl acetate, kaempferol-3,7-dimethyl ether, and 5-hydroxy-7-3',4'-trimethoxyflavanone) showed important topical and systemic anti-inflammatory activity in acute model, as well as antimycobacterial and antiprotozoal activities. In this paper, we describe the hepatoprotective and anti-inflammatory effects of the CHCl:MeOH extract in chronic model and the isolation of additional compounds (moretenone and lupeol acetate). The hepatoprotective activity was determined at 39 days using Balb/c mice with liver damage induced with an antitubercular drug (RIF/INH/PZA).

Hepatoprotective properties of oleanolic and ursolic acids in antitubercular drug-induced liver damage.

Objective: To estimate to what extent the mixture of ursolic acid and oleanolic acid, in addition to the antitubercular standard regime, affects the hepatotoxicity profile.

Methods: Liver injury was induced in male BALB/c mice by administering, per os and daily for 11 weeks, a combination of anti-Tubercular (anti-TB) agents Rifampicin (10 mg/kg), Isoniazid (10 mg/kg), and Pyrazinamide (30 mg/kg). The ursolic acid and oleanolic acid mixture at doses of 100 or 200 μg/mouse/day was subcutaneously injected throughout the entire study period (11 weeks).

Anti-inflammatory and toxicological evaluation of Moussonia deppeana (Schldl. & Cham) Hanst and Verbascoside as a main active metabolite.

Ethnopharmacological Relevance: Moussonia deppeana, known as Tlachichinole, is a Mexican medicinal plant used for treatment of inflammatory diseases, influenza, diarrhea, gastrointestinal disorders and arthritis.

Aim Of The Study: In this paper the antioxidant and anti-inflammatory activities as well as the acute and sub-acute toxicological effects were evaluated for the ethanolic extract from aerial parts of M. deppeana, also its phytochemical analysis is described.

A proteomic approach of pediatric astrocytomas: MiRNAs and network insight.

Unlabelled: Pediatric astrocytomas, a leading cause of death associated with cancer, are the most common primary central nervous system tumors found in children. Most studies of these tumors focus on adults, not on children. We examined the global protein and microRNA expression pattern by 2D SDS-PAGE, mass spectrometry (MALDI-TOF), and RT(2) miRNA PCR Array System.

[Survival of patients with malignant astrocytomas according to the expression of Ki67 antigen in a pediatric hospital].

Background: Pediatric patients with malignant gliomas and same histological diagnosis respond distinctly to treatment. It is thus necessary to determine other factors that may influence the response to treatment and survival. Over expression of the Ki67 protein has been associated with poor treatment response.

[Prognostic and survival factors among pediatric patients with ependymomas].

Background: Ependymomas constitute the third most common intracranial tumors in children. Risk factors include age, location, extent of surgical excision, and radiation therapy. Recently, chromosomal imbalances have been described.

Clinical and molecular parameters for risk stratification in Mexican children with medulloblastoma.

Background: Clinical, histological, and more recently, molecular factors have been described as important in survival of the patient with medulloblastoma. Best survival results include aggressive chemotherapeutic protocols. More exact risk analysis may differentiate patients who require aggressive treatments from those with low risk who may respond adequately to less aggressive protocols.

[ALK-1 positive anaplastic large cell lymphoma of the lung. Report of a pediatric case].

Ki-1 anaplastic large cell non-Hodgkin lymphoma is a well recognized clinical entity. The main clinical feature includes lymphadenopathy with mediastinal sparing. In the extranodal disease, which occurs in approximately half of the cases, the skin is the most common site; bone marrow, lung and central nervous system are generally not involved.
