- Abstract
In low- and lower middle-income countries (LMICs), timely access to primary care following thermal injury is challenging. Children with deep burns often fail to receive specialized burn care until months or years post-injury, thus suffering impairments from hypertrophic scarring or joint and soft tissue contractures. We aimed to examine the correlation between limited access to care following burn injury and long-term disability in children in LMICs and to identify specific factors affecting the occurrence of late burn complications. A systematic literature search was conducted to retrieve articles on pediatric burns in LMICs using Medline, Embase, the Cochrane Library, LILACS, Global Health, African Index Medicus, and others. Articles were assessed by two reviewers and reported in accordance with PRISMA guidelines. Of 2896 articles initially identified, 103 underwent full-text review and 14 met inclusion criteria. A total of 991 children who developed long-term burn sequelae were included. Time from injury to consultation ranged from a few months to 17 years. Factors associated with late complications included total body surface area burned, burn depth, low socio-economic status, limited infrastructure, perceived inability to pay, lack of awareness of surgical treatment, low level of maternal education, and time elapsed between burn injury and reconstructive surgery., (Copyright © 2019.

- Abstract
Peripheral nerve injuries (PNI) are common and frequently afflict otherwise healthy individuals after traumatic or iatrogenic events. Adjuvant therapies to improve functional outcomes after surgical repair of PNI have been investigated extensively in preclinical studies; however, to date, none have been clinically proven to have a notable therapeutic effect. FK506 (tacrolimus), a US Food and Drug Administration-approved systemic immunosuppressant, has demonstrated promising neuro-regenerative properties in both animal studies and clinical reports, but its adverse effects when systemically administered have precluded its broader applicability for patients with PNI. Recent advances in bioengineered drug delivery systems have made local FK506 delivery to a site of PNI an intriguing method of promoting peripheral nerve regeneration, with promising results in preclinical translational investigations. This review summarizes the preclinical and clinical evidence for FK506's beneficial effect in promoting peripheral nerve regeneration when administered systemically and locally., (Copyright © 2020 American Society for Surgery of the Hand.

- Abstract
Facial reanimation provides patients affected by chronic facial paralysis a chance to regain basic human functions such as emotional expression, verbal communication, and oral competence for eating and swallowing, but there is still no consensus as to the best way to measure surgical outcomes. We performed a literature review to investigate the different functional outcomes that surgeons use to evaluate facial function after reanimation surgery, focusing on outcomes other than facial expressions such as speech, oral competence, and patient quality of life/satisfaction. A total of 37 articles were reviewed, with the majority reporting outcomes through subjective facial expression ratings and only 15 dealing with other functional outcomes. In particular, outcomes related to oral competence and speech were reported inconsistently. Facial reanimation patients would benefit from a unified movement to create and validate through consensus, an outcomes reporting system incorporating not only facial expression, but also oral competence, speech, and patient-reported quality of life, to enable global patient assessment., (Crown Copyright © 2018.

- Abstract
Background: Post-surgical pyoderma gangrenosum (PSPG) presents as a rapidly expanding cutaneous ulcer at a site of surgery with potentially devastating consequences. We systematically reviewed the English and foreign language literature to identify risk factors for PSPG and propose a management strategy., Methods: A systematic review was completed in PubMed, Medline, Embase, and Cochrane Database for all published reports of PSPG from January 1946 to June 2013. We manually examined bibliographies for relevant references and used Google Translate for articles in foreign languages, including Italian, Japanese, German, Dutch, Turkish, Spanish, Chinese, Dutch, Russian, Portuguese, and Czech., Results: We identified 220 cases of PSPG (mean age 52.8 years, range 5-85 years). Thirty-seven patients (16.8%) had a history of pyoderma gangrenosum, nineteen (8.6%) had a hematologic disorder such as leukemia or lymphoma, thirteen (5.9%) had inflammatory bowel disease, and eight (3.6%) had rheumatoid arthritis. PSPG occurred most commonly after breast (25%), cardiothoracic (14%), abdominal (14%), and obstetric (13%) surgeries. The most common breast procedures were bilateral reduction mammoplasty (45%), breast reconstruction (25%), and lumpectomy or mastectomy (11%). Signs of wound complication occurred on average 7.0 days after surgery. Nineteen patients (8.6%) at risk for PSPG received perioperative corticosteroids during skin grafting or later surgeries with a favorable outcome., Conclusions: Patients with a history of pyoderma gangrenosum, rheumatoid arthritis, inflammatory bowel disease, or hematologic malignancy who are undergoing breast, cardiothoracic, or abdominal surgeries should be carefully observed for post-operative ulceration at incision sites. Debridement should not be performed before dermatologic consultation to assess for PSPG. Patients at risk of PSPG undergoing breast surgery may benefit from perioperative prednisone to prevent PSPG which can lead to destructive wound enlargement and significant scarring., (Copyright © 2014 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

- Abstract
Marjolin's ulcer is an aggressive ulcerating cutaneous malignancy that may arise in chronically inflamed or traumatized skin. Frequently overlooked, this rare condition is classically associated with burn scars, with the process of malignant degeneration typically occurring over two to three decades. The most common histopathological pattern is squamous cell carcinoma; however, compared to typical squamous cell carcinomas, Marjolin's ulcers have an increased rate of metastasis. The correlation between radiotherapy for benign hypertrophic scarring and carcinogenesis is controversial, with few reports in the literature. We present a unique case of a 61 year old Caucasian male who was burned by scald at age 4, received radiotherapy for his post-burn hypertrophic scars, and later developed multiple Marjolin's ulcers on his left arm, chest, and right temporal scalp., (Crown Copyright © 2013.

- Abstract
Background: Neonates with certain forms of severe congenital heart disease (CHD) diagnosed prenatally might have better outcomes in comparison with those diagnosed after birth. The proportion of prenatally detected neonates with severe CHD and the effect of prenatal diagnosis on clinical outcomes have not been previously investigated in Canada., Methods: We retrospectively studied infants in Alberta, Canada, who required surgical or catheter intervention for CHD at younger than 1 year of age, between January 2007 and December 2010, and pregnancy terminations affected by CHD., Results: Of the 374 subjects identified (327 infants, 47 pregnancies with termination), 188 (50%) were detected prenatally. Failure of prenatal diagnosis was associated with anomalies not involving the 4-chamber view on ultrasound (odds ratio, 1.86; 95% confidence interval, 1.48-2.35; P < 0.001) and region of residence (P = 0.04). Prenatal detection was associated with fewer days to hospital admission (P < 0.001), fewer days to surgery (P = 0.003), and greater use of prostaglandins (P = 0.001). Infants diagnosed prenatally who underwent surgery within 15 days of age had higher preductal O2 saturations (P = 0.04), fewer days to admission (P = 0.03), and less frequently required preoperative intubation (P = 0.004), and inotropes (P = 0.001). Pregnancy termination occurred among 49% of fetuses detected before 24 weeks' gestation., Conclusions: Only 50% of fetuses and/or neonates with severe CHD managed in Alberta have a prenatal diagnosis. The likelihood of prenatal detection is influenced by the status of the 4-chamber view on ultrasound and the region of maternal residence indicating heterogeneous access to fetal echocardiography within Alberta. Prenatal detection might improve clinical outcomes for neonates with severe CHD., (Copyright © 2013 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.)

- Abstract
Forty-seven strains of H9 subtype avian influenza viruses identified by specific reverse transcription-PCR method were isolated from the chicken and duck flocks in different areas of China during the 2002 to 2009 epizootic period. Hemagglutinin (HA) genes of these strains were sequenced and analyzed with the representative strains published in GenBank. The results indicated that the HA genes of these strains and the vaccine strains displayed nucleotide homologies ranging from 91.7 to 96.6% and amino acid homologies ranging from 92.3 to 95.7%, respectively. Analysis of the mature peptide sequences of these HA genes showed that the presence of leucine at position 216 (corresponding to residue 226 in H3 numbering) indicated a preference to the binding of alpha (2-6) sialic acid receptors, which was the same as human isolates. Extra potential glycosylation sites appeared in the HA genes of most tested isolations compared with the vaccine strains. The HA cleavage sites of most of the strains were the 335PSRSSR downward arrow GLF341, but all of the strains met the characteristics of low-pathogenic avian influenza. The results of phylogenetic analysis indicated that all 47 strains and the current vaccine strains belong to the same phylogenetic lineage h9.4.2, but they had some genetic deviation in the last decade. Compared with the vaccine strains, 7 mutations were found in the antigen epitope region of the HA genes of the field strains. These results suggested that the commercial vaccine might not induce satisfactory prevention against infection of H9N2 avian influenza virus.

- Abstract
Muscovy duck parvovirus (MDPV) usually causes high morbidity and mortality in 1- to 3-wk-old Muscovy ducklings due to serious infections, which is an imminent threat to the commercial duck industry in China. The objectives of this study were to develop and evaluate a simple, rapid, and inexpensive loop-mediated isothermal amplification (LAMP) method for specific detection of MDPV and to compare it with the PCR method in rapidity, sensitivity, and accuracy. The novel LAMP assay used a set of 4 specific primers to recognize 6 distinct genomic sequences of capsid protein (VP3) from MDPV, which could be completed within 50 min at 63 degrees C in a simple water bath. The diagnostic results demonstrated that the LAMP assay detected all 7 preserved MDPV isolates, had no cross-reactivity with other duck pathogens (i.e., goose parvovirus, duck plague virus, H9N2 avian influenza virus, duck hepatitis type virus I, and Muscovy duck reovirus). The LAMP assay was at least 10-fold more sensitive than the routine PCR assay and obtained more sensitivity in 61 clinical samples. Therefore, the newly developed LAMP assay provides a specific and sensitive means for detecting MDPV and can be simply applied both in field conditions and in laboratory operations in a cost-effective manner with primary care facilities.
