Burns often cause the damaged tissue to produce a large amount of exudate and the formation of blisters on the wound. The burn blister fluid contains a large number of molecules related to wound healing, which can reflect the state of local tissue microenvironment of the burn wound. Analyzing relevant information such as cellular components, signal mediators, and protein molecules in burn blister fluid is helpful to understand the local reaction and tissue microenvironment of burn wounds, and then help clinical burn treatment. In this article, by understanding the production mechanism of burn blister fluid, discussing its role in wound evaluation, and integrating the research progress of burn blister fluid in proteomics, metabolomics, cellular components, and pharmacokinetics, we propose our thoughts and prospects on the research of burn blister fluid, in order to provide assistance for clinical evaluation and treatment of burn wounds, and also provide idea for the follow-up study of burn blister fluid.

BACKGROUND: An Alveolar-pleural fistula is communication between the alveoli and the pleural space that may result in intractable pneumothorax, severe infection, respiratory failure, physical weakness, and even death.CASE: A 70-year-old male underwent right hepatectomy with a cystic mass of the liver. During the operation, peak airway pressure abruptly increased and a serous fluid was regurgitated through the endotracheal tube. Lung isolation was immediately performed with a double-lumen endotracheal tube. Approximately 1,000 ml of exudate was drained through endotracheal tube. Thoracostomy was performed at right lung. Analysis of fluid from endotracheal tube and pleural effusion consistent with parapneumonic effusion.CONCLUSIONS: We presented a case of alveolar-pleural fistula caused by pneumonia presenting with massive exudate fluid regurgitated from the endotracheal tube that was managed with bronchial suction, lung isolation, and thoracostomy and improved without surgical repair of the fistula.

PURPOSE: The purpose of this study was to identify minimum data sets for oral mucous integrity-related documentation and to analyze nursing records for oral care.METHODS: To identify minimum data sets for oral status, the authors reviewed 26 assessment tools and a practical guideline for oral care. The content validity of the minimum data sets was assessed by three nurse specialists. To map the minimum data sets to nursing records, the authors examined 107 nursing records derived from 44 patients who received chemotherapy or hematopoietic stem cell transplantation in one tertiary hospital.RESULTS: The minimum data sets were 10 elements such as location, mucositis grade, pain, hygiene, dysphagia, exudate, inflammation, difficulty speaking, and moisture. Inflammation contained two value sets: type and color. Mucositis grade, pain, dysphagia and inflammation were recorded well, accounting for a complete mapping rate of 100%. Hygiene (100%) was incompletely mapped, and there were no records for exudate (83.2%), difficulty speaking (99.1%), or moisture (88.8%).CONCLUSION: This study found that nursing records on oral mucous integrity were not sufficient and could be improved by adopting minimum data sets as identified in this study.

BACKGROUND: Split-thickness skin grafts (STSGs) are commonly used in the reconstruction of skin defects induced by trauma or burns. Although STSGs are used to successfully treat various wound types, donor site wounds can be challenging, and complications often develop. Therefore, optimal donor site dressings are required. In this study, we introduce an evidence base for patterns in how the discharge amount decreases over time, with the goal of providing insights into the selection of dressing materials. METHODS: Twenty patients with burns who received STSGs harvested from the thigh between January 2016 to April 2017 were prospectively reviewed. A donor site dressing with foam was changed daily. The weight of the foam dressing was measured before and after placement on the donor site. The wound area was calculated using Visi-Trak. The mean weight of the discharge amount per unit area (g/10 cm2) was calculated. RESULTS: The mean weight of the discharge amount per unit area (g/10 cm2) decreased from 3.84 to 2.02 (P < 0.05) and 1.09 (P < 0.05) on postoperative days 5 and 10, respectively. It further decreased to 0.61 by postoperative day 14. CONCLUSIONS: To prevent infections induced by donor site leakage, the use of highly-absorptive foam materials until 5 days after the operation is beneficial. Moreover, hydrocolloid or highly-absorptive foam materials can be used to promote re-epithelialization of the donor site after 5 days postoperatively. For re-epithelialization and wound protection, it is effective to use hydrocolloid materials starting on postoperative day 10.

BACKGROUND: Sickle cell anemia (SCA) is a hereditary chronic hemolytic anemia with several clinical consequences. Intravascular sickling of red blood cells leads to multi-organ dysfunction. Moreover, several biochemical abnormalities have been associated with SCA. Gum arabic (GA) is an edible dried gummy exudate obtained from Acacia Senegal tree. GA showed antioxidant and cytoprotective activities and demonstrated protection against hepatic, renal, and cardiac toxicities in experimental rats. We hypothesized that regular intake of GA improves renal and liver functions in patients with SCA. METHODS: Forty-seven patients (5–42 yr) carrying hemoglobin SS were recruited. The patients received 30 g/day GA for 12 weeks. Blood samples were collected before administering GA and then after 4, 8, and 12 weeks. Liver enzymes, total protein, albumin, electrolytes, urea, creatinine, and uric acid were determined in the serum. The study was approved by the Al Neelain University Institutional Review Board and Research Ethics Committee Ministry of Health. The trial was registered at ClinicalTrials.gov (identifier: NCT02467257). RESULTS: GA significantly decreased direct bilirubin level [statistical significance (P-value)=0.04]. It also significantly decreased serum alanine transaminase level after 4 weeks, which was sustained till the 8th week. GA, however, had no effect on serum aspartate transaminase level. In terms of renal function, GA decreased serum urea level but the effect was not sustained after the first month. CONCLUSION: GA may alter the disease severity in SCA as demonstrated by its ability to decrease direct bilirubin and urea levels in the serum.

PURPOSE: This study analyzed the treatment effects of drain insertion in the posteromedial portal after an arthroscopic synovectomy and posterior septum resection for pyogenic arthritis. MATERIALS AND METHODS: From June 2005 to December 2016, 56 cases (55 patients, 1 case of bilateral knee) were diagnosed with pyogenic arthritis and arthroscopic treatment was performed. Fourteen patients (25.0%) were identified with causative organisms. The average follow-up period was 12.3 months, and the mean age was 67.8 years old. Twenty-four cases were males and 31 cases were females. Kellgrene–Lawrence grade (K–L grade) I was 6 patients, II was 20 patients, III was 11 patients, and IV was 18 patients. Surgery was performed through six portal. The posterior septum was removed and a drainage tube was inserted from the posterior medial side to the posterior side of the joint. The Lysholm score was used after surgery for a functional evaluation. The K–L grade at the time of admission and at the last follow-up were compared for a radiological evaluation. RESULTS: The mean normalization period of the C-reactive protein was 59.8 days (6–164 days). Intravenous antibiotics were used for an average of 37.1 days. The results of the functional evaluation revealed a mean Lysholm score of 64.5 (30–98) in a total of 56 cases. Two reoperations was performed, but the treatment was completed with same method in all patients. The K–L grade was similar at the time of surgery and at the last follow-up (p>0.05). CONCLUSION: The method of drain insertion in the posteromedial portal after arthroscopic synovectomy and posterior septum resection for pyogenic arthritis is an effective technique that can obtain satisfactory results by inducing proper exudate discharge.

PURPOSE: To investigate the short-term efficacy and safety of ranibizumab in the routine clinical setting in patients with neovascular age-related macular degeneration and to analyze the associated factors for visual outcome. METHODS: This was a post-hoc analysis of a ranibizumab regulatory post-marketing surveillance study in which 4,136 patients were enrolled and followed for 12 weeks. Change in best-corrected visual acuity (BCVA), size of choroidal neovascularization, and the presence of hemorrhage and exudate were analyzed and the association between BCVA change and baseline characteristics were investigated. Data on ocular and systemic adverse events were collected. RESULTS: Mean BCVA improved significantly and mean BCVA change was the logarithm of the minimal angle of resolution 0.13 ± 0.01 (p < 0.001). A lower baseline BCVA and younger age were significant predictive factors for visual improvement or maintenance (≥0 lines). For greater visual acuity gain (≥3 lines), no treatment history, lower baseline BCVA, younger age, and classic-type choroidal neovascularization were significant predictive factors. No new safety signals were found. CONCLUSIONS: In this study, conducted in real-world clinical practice with a large number of neovascular age-related macular degeneration patients, visual and anatomical outcomes improved significantly after three monthly ranibizumab treatments. Treatment-naive patients had a higher chance of greater visual gain (≥3 lines) than non-naive patients.

Herpes simplex virus (HSV) is a common pathogen, that causes a broad spectrum of diseases, ranging from minor skin infections to severe encephalitis and widespread infections. Acute retinal necrosis (ARN), one of the most serious manifestations of HSV infection, is defined as a rapidly progressing necrotizing retinopathy that presents discrete areas of circumferential retinal necrosis, along with signs of uveitis, vitreitis, and retinal vasculitis. We encountered a case of a female infant, born at 33 weeks of gestation with a body weight at birth of 2,080 g, who had ARN and encephalomalacia due to HSV infection. ARN associated with HSV infection should be suspected when nonspecific retinal exudates are observed in neonates, especially preterm infants.

PURPOSE: In the present study, the volume of hard exudates (HEs) was quantitatively measured using optical coherence tomography (OCT) and the agreement and correlation with area of HEs in fundus photography were analyzed. METHODS: The medical records of patients with diabetic macular edema who underwent focal laser treatment and were followed up more than 3 months were retrospectively evaluated. An automated customized program designed for measuring HE volume was used. The HEs in each OCT B-scan binary image were measured using 512 × 128 pixels, 6 mm × 6 mm OCT cube scans. The volume was measured by summing the segmented HEs in each 128 B-scan image. The area was measured in 6 mm x 6 mm fundus photography. The volume and area were measured before and 3 months after the treatment. The agreement of increase and decrease in HEs, and the correlation of volume and area of HEs were analyzed. RESULTS: A total of 35 patients (39 eyes) were included in the study. The volume was significantly reduced from 0.07978 to 0.02565 mm³ at 3 months (p < 0.001). The area was also significantly reduced from 15.35 to 8.60 mm² at 3 months (p < 0.001). The volume was decreased in 34 eyes and increased in 5 eyes. The area was decreased in 37 eyes and increased in 2 eyes. A significant correlation between volume and area was found (p < 0.001) as well as agreement between increase and decrease in volume and area. CONCLUSIONS: In the 3-dimensional quantitative volumetric analysis, the volume and area of HEs were correlated and the direction of increase and decrease was concordant. Considering the distribution of HEs in multiple layers of the retina, volumetric analysis could be considered a substitute for the analysis of HE area.
