Perineal groove is a rare anoperineal congenital malformation, usually occurring in girls, unknown to many pediatricians. We report the case of a 17-day-old girl admitted for urinary infection, who presented a wet sulcus with mucous membrane, extending from the vaginal fourchette to the anterior border of the anus. The diagnosis of perineal groove was clinically confirmed, after elimination of misdiagnosis such as infection or trauma. This benign malformation tends to be self-epithelialized in the 1st year of life, and no surgical treatment is recommended, except for cosmetic reasons or for recurrent infections...

The intensive use of silver nanoparticles (AgNPs) in cosmetics and textiles causes their release into sewer networks of urban water systems. Although a few studies have investigated antimicrobial activities of nanoparticles against environmental bacteria, little is known about potential impacts of the released AgNPs on sulfate reducing bacteria in sewers. Here, we investigated the effect of AgNPs on Desulfovibrio vulgaris Hidenborough (D. vulgaris), a typical sulfate-reducing bacterium (SRB) in sewer systems...

Human research with hallucinogens such as lysergic acid diethylamide (LSD) has been ongoing in the USA since 1949. During the 1960s, LSD was investigated for a variety of psychiatric indications, including the following: as an aid in treatment of schizophrenia; as a means of creating a "model psychosis"; as a direct antidepressant; and as an adjunct to psychotherapy. Studies with all drugs, including LSD, have always been conducted under federal regulatory controls, including the 1938 Food Drug and Cosmetic Act (FDCA; which ensured the safety of drugs) and the 1962 Kefauver-Harris Amendments to the FDCA (which described appropriate scientific methodology and ensured drug efficacy)...

Although several serine collagenolytic proteases from bacteria were reported, none has been used to prepare bioactive collagen peptides. MCP-01 is the most abundant extracellular protease of deep-sea Pseudoalteromonas sp. SM9913 and is a serine collagenolytic protease with high efficiency on fish collagen hydrolysis. Here, we set up a pilot scale process to ferment SM9913 for extracellular protease production. With SM9913 extracellular protease as a tool, a process to prepare collagen oligopeptide-rich hydrolysate from codfish skin was set up, which was further scaled up to pilot (100 L) and plant (2000 L) levels with yields >66%...

Miin Roh, Nahyoung Grace Lee, John B Miller
MIRAgel (MIRA, Waltham, MA) is a hydrogel buckle that was introduced in 1979 as a new scleral implant for the treatment of retinal detachment. Long-term follow-up of more than 10 years revealed that the hydrolysis of the synthetic hydrophilic material leads to marked expansion of the substance, causing complications such as buckle extrusion and intrusion, eye motility disorder, cosmetic deformities, and periocular infections. Removal of the implant is the treatment of choice in cases with complications, but it is technically difficult due to the friability of the implant, severe scleral ectasia, and relatively high rate of redetachment after removal...

Particle dispersions, such as pigment-based inks, comprise weakly bound, milled nanoparticles. The properties of these pigments depend on both their chemical composition, as well as a rather complex structural hierarchy, which emerges from these dispersions. The emergence of structure under semi-dilute conditions is related to the structure of the dilute particles, the particle spacing (mesh size), processing history, and the interaction potential. Kinetic simulations could predict such emergence using these input parameters...

When encountered in children, xanthomas are most commonly associated with a group of disorders known as familial hyperlipidemias. Aside from cosmetic concerns, these xanthomas are typically asymptomatic, but when generalized pruritus is a prominent associated symptom, clinicians should consider a different set of diagnoses that includes cholestasis of the liver. In this article we present two illustrative cases of children with cholestatic disease, pruritus, and xanthomas and discuss other disorders that may include this triad...

Collagen is a fibrillar protein that conforms the conjunctive and connective tissues in the human body, essentially skin, joints, and bones. This molecule is one of the most abundant in many of the living organisms due to its connective role in biological structures. Due to its abundance, strength and its directly proportional relation with skin aging, collagen has gained great interest in the cosmetic industry. It has been established that the collagen fibers are damaged with the pass of time, losing thickness and strength which has been strongly related with skin aging phenomena [Colágeno para todo...

Minimally invasive video-assisted thyroidectomy (MIVAT) is known and used worldwide, it combines the advantages associated with endoscopic magnification with those due with traditional surgery. In selected patients, it should be considered a safe and valid alternative. Indeed, a lot of comparative studies have demonstrated the advantages of MIVAT in terms of low rate of complications, reduced postoperative pain, improved cosmetic results and higher patient satisfaction over traditional surgery. Anyway, for obtaining the best results, with similar or even less complication rate than traditional surgery, surgeons should be well trained, acquired confidence with a smaller surgical incision and with the use of endoscopic instruments...

Silicone injected for cosmetic purposes can provoke an inflammatory granulomatous response. In turn, silicone granulomas can lead to hypercalcemia, which is a rare, though potentially life-threatening condition. Hypercalcemia is a nonspecific laboratory finding with many potential etiologies. It may be difficult for clinicians to diagnose silicone-induced hypercalcemia, since the history of cosmetic silicone injections may not be elicited from the patient. Positron emission tomography using F-18-fluorodeoxyglucose (FDG-PET) can be used to evaluate patients with unexplained hypercalcemia as a means of searching for an occult malignancy or granulomatous process...
