The lung microbiota has received less attention compared to other body sites, in part because its study carries special technological difficulties related to obtaining reliable samples as compared to other body niches. The limited number of studies on the sputum microbiota on TB patients and controls available so far have reported inconsistent, and sometimes, contradictory results. Aiming to clarify if changes in the lung microbiota composition are associated with pulmonary TB, we performed a meta-analysis of available data on microbiota of the lower respiratory tract in TB patients and healthy controls...

Previous studies have indicated that sirolimus (SRL) may be effective for HCC patients undergoing liver transplantation (LT). However, the following results are still contradictory and do not have a clear conclusion. Therefore, we conducted an updated meta-analysis by retrieving published data in EMBASE, PubMed, and the Cochrane Library up to October 2017. Both efficiency and safety of SRL were analyzed using pooled odds ratio (ORs) with 95% confidence interval (CIs). A total of 11 studies involving 7,695 HCC patients were included...

Isotretinoin is the most effective drug in the treatment of severe recalcitrant nodulocystic acne. However, treatment with this drug is associated with adverse effects, the most severe being teratogenesis. It has been estimated that 40% of pregnancies exposed to isotretinoin present spontaneous abortion and 35% develop embryopathy. We present the case of a newborn with a history of prenatal exposure to isotretinoin, a clinical entity that can be avoided, with severe congenital defects in the central nervous system and important facial dysmorphisms, with unfavorable clinical course...

Toxic epidermal necrolysis (TEN) is a rare and severe mucocutaneous disorder characterized by mucosal and epidermal necrosis and sloughing. This potentially life-threatening condition, together with the less severe Stevens-Johnson syndrome, is commonly caused by an immunologic reaction to medications and can lead to many long-term complications. The disorder initially presents with fever, malaise, and painful mucosal ulcerations (most commonly oral) but progresses to widespread cutaneous lesions. A 14-year-old male patient was prescribed minocycline for treatment of his acne by his primary care doctor...

BACKGROUND: Aromatase deficiency is a rare autosomal recessive genetic disorder with an unknown incidence. Aromatase converts androgens into estrogen in the gonadal and extra-gonadal tissues. Aromatase deficiency causes ambiguous genitalia in the female fetus and maternal virilization (hirsutism, acne, cliteromegaly, deep voice) during the pregnancy due to increased concentration of androgens. METHODS AND RESULTS: The-nineteen-month-old girl was assessed due to ambiguous genitalia There were findings of maternal virilization during pregnancy...

The popular characterisation of acne as a mundane and insignificant feature of adolescence sits at odds with academic studies showing the detrimental impacts of the condition on people of various ages. Drawing from in-depth qualitative interviews with 13- to 25-year olds living in England, this article will consider some of the tensions between two messages about acne through the ambiguities in young people's narratives. Consistent with existing literature on skin conditions and visual differences more broadly, participants in the study recounted ways in which acne negatively shaped their lives socially and emotionally...

Within the field of dermatology, advances in the use of light emitting diodes (LEDs) have led to their clinical application for a variety of medical and cosmetic uses. Of note, one phototherapy device has demonstrated beneficial effects over a range of clinical applications (Omnilux™; GlobalMed Technologies, Glen Ellen, California). The study included a literature review of published studies. Using LEDs with frequencies of 415nm (blue), 633nm (red), and 830nm (infrared), this device has demonstrated significant results for the treatment of medical conditions, including mild-to-moderate acne vulgaris, wound healing, psoriasis, squamous cell carcinoma in situ (Bowen's disease), basal cell carcinoma, actinic keratosis, and cosmetic applications...

Our understanding of the microbiome and the role of P. acnes in skin homeostasis and acne pathogenesis is evolving. Multiple methods for sampling and identifying the skin's microbiome exist and understanding the differences between the abilities of various methods to characterize the microbial landscape is warranted. This study compared the microbial diversity of samples obtained from the cheeks of twenty volunteers, collected by surface swab, pore strips, and cyanoacrylate glue follicular biopsy, all sequenced with 16S rRNA sequencing (V1-V3) and whole-genome metagenomic sequencing (WGS)...

BACKGROUND: The Gram-positive, anaerobic-aerotolerant bacterium Cutibacterium acnes is a commensal of human healthy skin, subdivided into six main phylogenetic groups or phylotypes: IA1, IA2, IB, IC, II and III. To decipher how far C. acnes specific subgroups are involved in disease physiopathology, different molecular typing methods have been developed to identify these subgroups (i.e. phylotypes, clonal complexes, SLST-types). However, as there were several molecular typing methods developed over the last decade, comparing the results from one article to another became a difficult task...

BACKGROUND: Acne is very common skin condition. Most patients with acne will have a degree of scarring as a result of their acne. In patients with darker skin color the scarring can be further complicated by hyperpigmentation. Several treatment options can be used to improve acne scarring, however the problem of post acne hyperpigmentation is not often addressed. This study especially focus on the treatment of pigmented post acne scarring using skin microneedling. AIMS: The primary objective is to assess the improvement of pigmentation of acne scarring in patients with dark skin using microneedling...

Clinical Question: Are light therapies effective and safe for treating acne? Bottom Line: The evidence for all light therapies remains weak and inconclusive. Red-light methyl aminolevulinate-photodynamic therapy (MAL-PDT) was the only treatment associated with a small though clinically insignificant reduction in the number of inflamed lesions and in global improvement as assessed by an investigator in moderate to severe acne. Red-light MAL-PDT was not associated with higher rates of severe adverse effects than placebo or no treatment...
