A 24-year old woman presented with hemorrhagic vesicles on her legs. She had taken sibutramine (Reductil(R), Abbott Labs., Seoul, South Korea) for 3 months and developed skin lesions the week before. A skin biopsy showed leukocytoclastic vasculitis with conspicuous eosinophilic infiltration of the tissue. These lesions showed improvement after discontinuation of sibutramine. However, 3 months later the skin lesions recurred on other sites on the lower extremities when the patient was rechallenged with the same drug for 2 weeks. Herein, we report the first case of necrotizing vasculitis induced by sibutramine.

BACKGROUND: The two common serological test methods used for initial diagnosis of acute Mycoplasma pneumoniae (MP) pneumonia are particle agglutination assay (PA) and enzyme immunoassay (EIA). We compared the differences between the two methods and suggest a test method more suitable for clinical laboratories. METHODS: A total of 35 patients (18 adult and 17 pediatric) performed MP specific antibody test using PA (Serodia-Myco II, Fujirebio, Japan) and EIA (Ani Labsystems, Finland) methods. IgM and IgG antibodies were measured separately by EIA method. PA and both IgM and IgG EIA were tested in 26 patients and PA and IgG-EIA were tested in 9 patients. RESULTS: The concordance rates between PA and EIA were 57.7% for IgM and 65.7% for IgG antibodies. Positive PA results showed better agreement with IgG (77.8%) than IgM (38.9%), while negative PA results showed better agreement with IgM (100%) than IgG EIA results (25%). In adult patients, the correlation between PA titers and IgM (r=0.852, P <0.01) and IgG values (r=0.517, P <0.05) were statistically significant. In pediatric patients, the correlation between PA titers and IgG values (r=0.842, P <0.01) was statistically significant. CONCLUSIONS: In this study, we observed that PA and EIA may not be used alternatively. Therefore, we suggest that use of both PA and IgM-EIA will be the optimal choice for laboratories. However, when laboratories are required to select one from PA or EIA, PA may be more useful to diagnose MP infection.

Brain diseases and damages come in many forms such as neurodegenerative diseases, tumors, and stroke. Millions of people currently suffer from neurological diseases worldwide. While Challenges of current diagnosis and treatment for neurological diseases are the drug delivery to the central nervous system. The Blood–Brain Barrier (BBB) limits the drug from reaching the targeted site thus showing poor effects. Nanoparticles that have advantage of the assembly at the nanoscale of available biomaterials can provide a delivery platform with potential to raising brain levels of either imaging therapeutic drugs or imaging. Therefore, successful modeling of the BBB is another crucial factor for the development of nanodrugs. In this review, we analyze the in vitro and in vivo findings achieved in various models, and outlook future development of nanodrugs for the successful treatment of brain diseases and damages.

Aplasia cutis congenita (ACC) is an uncommon condition which is characterized by congenital, localized or widespread absence of skin or scar formation. Lesions can be multiple and may occur on any body surface, although they are mostly seen on the scalp as a solitary lesion. ACC is most often a benign isolated defect; but it can be associated with other physical anomalies or malformation syndromes. Adams-Oliver syndrome is a distinct subtype in which distal limb reduction is found in association with a solitary scalp defect. There is no single underlying cause of ACC; it may reflect a disruption of intrauterine skin development. A 25 day-old boy was referred to our clinic with a thick hemorrhagic crust, and a surrounding hairless atrophic scar on the midline over the skull vertex. He also had hypoplasia of the left 2nd to 5th toes since birth. The rest of the physical examination as well as an ultrasound examination of the brain were normal. Herein we report a rare case of ACC of the scalp accompanied by distal limb hypoplasia, Adamson-Oliver syndrome.

Cutaneous lymphadenoma is a rare distinctive benign adnexal tumor of unknown histogenesis. It usually presents as a slowly growing, skin-colored nodule on the head and neck. Histologically, this tumor is composed of dermal lobules with a biphasic pattern of epithelial and lymphoid cells. We report two additional examples of this peculiar neoplasm.

We report here on a 63-year-old woman who presented with recurrent bruise-like infiltrative plaques on the left leg without systemic symptoms or laboratory abnormalities. The histopathologic findings showed an infiltration of panniculus by small to medium-sized atypical lymphocytes. But the prominent lymphoid atypia, fat necrosis, vascular thrombosis, erythrophagocytosis and striking dominance of CD8+ lymphocytes seen in subcutaneous panniculitis-like T-cell lymphoma (SPTCL) were not detected. The diagnosis of atypical lymphocytic lobular panniculitis (ALLP) was made based on these histopathologic and clinical features. The lesions responded well to systemic steroid treatment. But the CD4/CD8 ratio in the later lesion was more decreased than that of the initial lesion, and the patient is under clinical follow up.

We report a case of cutaneous Mycobacterium (M.) abscessus infection in a 32-year-old woman who presented with a red infiltrated plaque on her left shin. No history of prior trauma was reported, but she had a history of habitual leg shaving. Skin biopsy specimen showed neutrophilic abscesses with poorly defined granulomas in the lower dermis and subcutaneous tissue, as well as some acid-fast bacilli. The microorganism was identified as M. abscessus by tissue culture and PCR-restriction fragment length polymorphism (PCR-RFLP) analysis. The patient was treated with clarithromycin and cefaclor for 4 months, and there was no evidence of recurrence at 6 month follow-up.
