Never say never again: A bone graft infection due to a hornet sting, thirty-nine years after cranioplasty.

CONCLUSION: This case illustrates an anecdotal example of very late CP infection, due to an unpredictable accident. Due to lack of consensus on risk factors and on conservative or surgical strategy in case of graft infection, we aimed to share our surgical experience. PMID: 28868201 [PubMed]

Conclusion EMC should be considered first from an EE’s perspective, addressing concerns at the PCB level. MEs can get involved when enclosing the PCB or device. This is a collaborative effort. Both specialties should work through planning and execution. The ability to leverage a range of materials and components for EM enclosures allows engineers to make informed choices to meet the EMC requirements of a device. When considered at early stages, engineers can make EM an integral part of the design approach.

CASE SUMMARY: A 62-year-old previously healthy man presented with left lower quadrant pain and fever. Physical examination showed left lower quadrant peritonitis. Computed tomography scan showed a pelvic abscess with extraluminal air (Fig. 1). Intravenous antibiotics were started, and CT-guided percutaneous drainage was performed. The drain was removed 1 week after discharge. One week later, he presented with dysuria and pneumaturia and was started on antibiotics. Colonoscopy confirmed diverticulosis with no other mucosal abnormalities. He underwent a successful laparoscopic sigmoidectomy with colovesical fistula takedown.

Gulii, Maria A. Teplonogova, Olga S. Ivanova, Alexander E. Baranchikov, Vladimir K. IvanovAbstractA series of polyimide/CeO2 nanocomposite films were fabricated based on three polymer matrices. The prepared films were characterized by scanning electron microscopy (SEM), thermomechanical analysis (TMA), and also simultaneous thermogravimetric (TGA) and differential thermal analysis (DTA), the latter two having been performed both in air...

Publication date: April 2020Source: Materials Science and Engineering: C, Volume 109Author(s): Yun-shan Wei, Zhi-cheng Niu, Feng-qi Wang, Kun Feng, Min-hua Zong, Hong WuAbstractPickering emulsion (PE) stabilized by bio-compatible polymer nanoparticles (NPs) was first developed for the encapsulation of lipophilic tocopheryl acetate (TA) for its application in cosmetics. The poly(lactide-co-glycolide) (PLGA)/poly(styrene-co-4-styrene-sulfonate) (PSS) NPs were prepared by solvent displacement, and then they were used as emulsifier particles to fabricate TA-encapsulated PE. It was found that the TA encapsulation efficiency was...

This study underscores the capacity of human DC to discriminate between live and inactivated S. aureus and, further, indicates that DC may represent a valuable experimental setting to test different inactivation methods with regard to the retention of S. aureus immunoregulatory properties. These and further insights may be useful for the development of novel therapeutic and prophylactic anti-S. aureus vaccine strategies.

Thompson2 and Tae Sung Jung1* 1Laboratory of Aquatic Animal Diseases, College of Veterinary Medicine, Gyeongsang National University, Jinju, South Korea 2Moredun Research Institute, Pentlands Science Park, Penicuik, United Kingdom Teleost fish, as with other vertebrates, rely on their innate immune system as a first line of defense against invading pathogens. A very important characteristic of the innate immune response is its ability to recognize conserved molecular structures, such as viral dsRNA and ssRNA. Mda5 is one of the three pattern recognition receptors (PRRs) that recogn...

Authors: Placinta IA, España-Gregori E, Rodrigo-Hernández A, Martínez-Rubio C, Safont-Albert J, Bort-Martí MÁ Abstract An 80 year-old woman with no relevant medical history, consulted for worsening of right palpebral itching and pain after an insect bite. Her eyelids had areas of laceration due to scratching, which rapidly progressed to fibrinoid necrosis over the first 24hours. Lesions were cultivated, revealing Streptococcus pyogenes and Staphylococcus aureus. The patient was admitted to hospital with the diagnosis of periorbital necrotising fasciitis, in order to receive treatm...

​Some medical conditions have signs and symptoms that significantly overlap, making a diagnosis a little more difficult. Epididymitis, testicular torsion, and torsion of the testicular appendage are examples, but orbital and preseptal cellulitis are others that can cause significant diagnostic confusion.Both conditions are more common in children than in adults, and preseptal or periorbital cellulitis is more common in children under 5. The preseptal and orbital spaces are separated by only a thin membranous septum that originates in the orbital periosteum and inserts into the tarsal plates. It is only this thin septum t...

Contributors : Philip O Scumpia ; Joshua S NormanSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusSuccessful host defense against pathogens requires innate immune recognition of the correct pathogen associated molecular patterns (PAMPs) by pathogen recognition receptors (PRRs) to trigger the appropriate gene program tailored to the pathogen. While many PRR pathways have been shown to contribute to the innate immune response to specific pathogens, the relative importance of each pathway for the complete transcriptional program elicited has not been examined in detail. Herein, we used RN...

This study examined the possibility that c-di-AMP released during S. aureus biofilm growth polarizes macrophages toward an anti-inflammatory phenotype via type I interferon signaling. DacA, the enzyme responsible for c-di-AMP synthesis in S. aureus, was highly expressed during biofilm growth, and 30 to 50% of total c-di-AMP produced from S. aureus biofilm was released extracellularly due to autolytic activity. S. aureus biofilm c-di-AMP release induced macrophage type I IFN expression via a STING-dependent pathway and promoted S. aureus intracellular survival in macrophages. These findings identify c-di-AMP as another mech...
