PURPOSE: To identify risk factors for developing pressure ulcers (PUs) in the acute care period of traumatic spinal fracture patients with or without spinal cord injuries (SCIs). METHODS: Data were collected prospectively in participating the National Spinal column/Cord Injury Registry of Iran (NSCIR-IR) from individuals with traumatic spinal fractures with or without SCIs, inclusive of the hospital stay from admission to discharge. Trained nursing staff examined the patients for the presence of PUs every 8 h during their hospital stay. The presence and grade of PUs were assessed according to the European Pressure Ulcer Advisory Panel classification. In addition to PU, following data were also extracted from the NSCIR-IR datasets during the period of 2015 - 2021: age, sex, Glasgow coma scale score at admission, having SCIs, marital status, surgery for a spinal fracture, American Spinal Injury Association impairment scale (AIS), urinary incontinence, level of education, admitted center, length of stay in the intensive care unit (ICU), hypertension, respiratory diseases, consumption of cigarettes, diabetes mellitus and length of stay in the hospital. Logistic regression models were used to estimate the unadjusted and adjusted odds ratio (OR) with 95% confidence intervals (CI). RESULTS: Altogether 2785 participants with traumatic spinal fractures were included. Among them, 87 (3.1%) developed PU during their hospital stay and 392 (14.1%) had SCIs. In the SCI population, 63 (16.1%) developed PU during hospital stay. Univariate logistic regression for the whole sample showed that marital status, having SCIs, urinary incontinence, level of education, treating center, number of days in the ICU, age, and Glasgow coma scale score were significant predictors for PUs. However, further analysis by multiple logistic regression only revealed the significant risk factors to be the treating center, marital status, having SCIs, and the number of days in the ICU. For the subgroup of individuals with SCIs, marital status, AIS, urinary incontinence, level of education, the treating center, the number of days in the ICU and the number of days in the hospital were significant predictors for PUs by univariate analysis. After adjustment in the multivariate model, the treating center, marital status (singles vs. marrieds, OR = 3.06, 95% CI: 1.55 - 6.03, p = 0.001), and number of days in the ICU (OR = 1.06, 95% CI: 1.04 - 1.09, p < 0.001) maintained significance. CONCLUSIONS These data confirm that individuals with traumatic spinal fractures and SCIs, especially single young patients who suffer from urinary incontinence, grades A-D by AIS, prolonged ICU stay, and more extended hospitalization are at increased risk for PUs; as a result strategies to minimize PU development need further refinement.

PURPOSE: The purpose of this study was to determine whether poor preoperative nutritional status in elderly patients exhibited a negative influence on postoperative clinical outcomes.METHODS: The medical records of 645 elderly patients were examined retrospectively. The patients had undergone major surgery between January 2017 and January 2018. Their nutritional status was measured using the Nutritional Risk Screening 2002. The data were analyzed using the chi-squared test, the Mann-Whitney U test, logistic regression, linear regression, Cox proportional hazards regression, and the Kaplan-Meier analysis.RESULTS: Preoperative malnutrition was found in 73 patients (11.3%). Poor preoperative nutritional status was significantly associated with pressure ulcers, length of hospitalization, discharge to patient care facilities rather than home, and mortality rate at three months.CONCLUSION: Preoperative malnutrition in elderly patients was associated with negative postoperative clinical outcomes. These results indicate that an effective nutritional program before surgery can lead to a more rapid postoperative recovery.

BACKGROUND: Complication rates after flap coverage for pressure ulcers have been high historically. These patients have multiple risk factors associated with poor wound healing and complications including marginal nutritional status, prolonged immobilization, and a high comorbidities index. This study utilizes the National Surgical Quality Improvement Program (NSQIP) to examine perioperative outcomes of flap coverage for pressure ulcers. METHODS: Data from the NSQIP database (2005–2015) for patient undergoing flap coverage for pressure ulcers was identified. Demographic, perioperative information, and complications were reviewed. One-way analysis of variance and Pearson chi-square were used to assess differences for continuous variables and nominal variables, respectively. Multivariate logistic regression was performed to identify independent risk factors for complications. RESULTS: There were 755 cases identified: 365 (48.3%) sacral ulcers, 321 (42.5%) ischial ulcers, and 69 (9.1%) trochanteric ulcers. Most patients were older male, with some degree of dependency, neurosensory impairment, high functional comorbidities score, and American Society of Anesthesiologists class 3 or above. The sacral ulcer group had the highest incidence of septic shock and bleeding, while the trochanteric ulcer group had the highest incidence of superficial surgical site infection. There was an overall complication rate of 25% at 30-day follow-up. There was no statistical difference in overall complication among groups. Total operating time, diabetes, and non-elective case were independent risk factors for overall complications. CONCLUSIONS: Despite patients with poor baseline functional status, flap coverage for pressure ulcer patients is safe with acceptable postoperative complications. This type of treatment should be considered for properly selected patients.

STUDY DESIGN: Cross sectional study. PURPOSE: To characterize the pattern of injury, describe the current clinical management, and determine the outcomes in traumatic spine injury (TSI) patients presenting to a major government hospital in Phnom Penh, Cambodia. OVERVIEW OF LITERATURE: There is a paucity of literature on epidemiology or current clinical practices for TSIs in Cambodia. The findings from this study can thus serve as a valuable resource for future progress in treating TSIs in low-income countries. METHODS: This study was a cross-sectional study of TSI patients admitted to Preah Kossamak Hospital in Phnom Penh, Cambodia. Demographics, cause of spinal injury, spinal level of injury, surgical procedures and techniques, complications, and American Spinal Injury Association (ASIA) grades were recorded and analyzed. RESULTS: Eighty patients were admitted with TSI between October 2013 and June 2014. Falls from heights were the most common cause of TSI, followed by road traffic accidents. 78% of the admitted patients underwent at least one surgical procedure. Without intraoperative imaging, 4 patients (6%) had wrong level surgery, and 1 patient (2%) had misplacement of pedicle screws. Sacral decubitus ulcers were the most common non-surgically related complication. Antibiotics were administered to >90% of patients. There were no in-hospital mortalities. Of the 60 spinal cord injury (SCI) patients, 32% (19/60) showed improvement in their ASIA grade at the time of discharge, and 52% (31/60) showed no change. At follow-up, 32% (19/60) of SCI patients reported improvement, and 8% (5/60) reported no change. However, 36 SCI patients (60%) were lost to follow-up. CONCLUSIONS: Despite technological limitations, outcomes of TSI patients in Cambodia appear favorable with evidence of clinical improvement and low mortality.

PURPOSE: The purpose of this study was to evaluate whether we have to stop the antiplatelet agents prior to hemiarthroplasty surgery in patients with displaced femur neck fractures to reduce postoperative complications. MATERIALS AND METHODS: We enrolled forty-three patients with displaced femur neck fractures who were treated by bipolar hemiarthroplasty and were taking antiplatelet agents. Group I included 21 patients who discontinued antiplatelet agents and had delayed operations at an average 5.7 days and group II included 22 patients who had had early operations within 24 hours without stopping the antiplatelet agents. We compared the pre- and postoperative levels of hemoglobin, the volume of postoperative transfusion requirement and complications. Student's t-test and chi-square test were used for statistical analysis. RESULTS: The average differences between preoperative and postoperative hemoglobin was 1.4+/-0.4 g/dL decrease in group I and 2.1+/-0.5 g/dL decrease in group II (P<0.001). Patients who received a blood transfusion were 11 in group I and 13 in group II (P=0.66). Total number of blood transfusion was 13 pints in group I and 18 pints in group II (P=0.23). Pneumonia occurred in one patient in each group. Four pressure sores and three diaper rashes were developed in group I. But there were no patients requiring massive transfusion, reoperation due to hematoma and infection in each group. CONCLUSION: Although continuous taking of antiplatelet agents in displaced femur neck fracture is associated with an increased risk of postoperative bleeding, taking an antiplatelet agent itself is not a contraindication of early surgery.

Marjolin's ulcer is a rare malignancy arising from various forms of scars, mainly an old scar resulted from burn. The second most common origin is malignant degeneration arising from tissue within osteomyelitis fistulae. Not uncommonly, the lesions may arise secondary to ulcers due to venous insufficiency or pressure sores. The pathology of the majority of Marjolin's ulcer is a well-differentiated squamous cell carcinoma. The exact reason for an ulcer which undergoes a malignant transformation is unknown. The pathologic diagnosis is the gold standard. Surgery remains the preferred treatment after diagnosis is reached. Wide surgical excision with margins up to 2-3 cm has been suggested. The necessity of whether lymphatic dissection should be executed, or radiotherapy and chemotherapy following surgery is still in dispute. This article deals with the etiology of Marjolin's ulcer and its pathological grading, diagnosis, treatment, prognosis, and prevention, with a hope to provide some useful clinical information.

OBJECTIVETo evaluate the therapeutic effects of VSD combined with irrigation of oxygen loaded fluid on chronic wounds in diabetic patients.

METHODSTwenty-six diabetic patients hospitalized in Nanfang Hospital of Southern Medical University from September 2010 to June 2013, with chronic ulcers on lower extremities conforming to the inclusive criteria, were divided into group VSD (n = 8), VSD + irrigation control group (VSD + IC, n = 9), VSD + oxygen loaded fluid irrigation group (VSD OLI, n = 9) according to the random number table. After gross observation was conducted and wound secretion was sent for bacterial culturing right after admission, debridement was performed. During the debridement, granulation tissue of wound center was harvested for determination of the activity of lactate dehydrogenase (LDH) and succinate dehydrogenase (SDH) with ELISA. After debridement, the patients in group VSD were treated with VSD (negative pressure from -30 to -25 kPa, the same below); the patients in group VSD + IC were treated with VSD combining irrigation of normal saline; the patients in group VSD + OLI were treated with VSD combining normal saline loaded with oxygen (flow of 1 L/min ) irrigation. Drainage tube blockage was recorded and its incidence rate was recorded during the treatment. On post treatment day (PTD) 7, tissue exudates were collected and analyzed with blood gas analyzer for determining the partial pressure of oxygen of the exudate. After the VSD was terminated, bacterial culture was conducted as before, and the bacterial clearance rate was calculated. After the calculation of granulation tissue coverage rate, the granulation tissue in the center of the wound was harvested for histopathological observation with HE staining; morphological characteristics and density of mitochondria were observed with transmission electron microscopy; the activity of LDH and SDH was estimated as before; microvascular density (MVD) was counted after CD31 antibody immunohistochemical staining. Then the second stage operation was performed. The method of second stage operation was recorded and survival rate of grafted skin or flap was calculated. Data were processed with one-way analysis of variance, LSD- t test, rank sum test, or Fisher's exact test.

RESULTS(1) The gross observation showed that before debridement there was only necrotic tissue without granulation tissue in the wounds of patients in all the 3 groups. On PTD 7, granulation tissue was found in the wounds of patients in all the 3 groups. HE staining showed that there were more abundant newborn microvessels and regularly arranged fibroblasts in the wounds of group VSD + OLI; less newborn microvessels and relatively sparsely fibroblasts were observed in the wounds of group VSD + IC. There were only sparse newborn microvessels and fibroblasts in the wounds of group VSD. (2) Rates of drainage tube blockage, granulation tissue coverage, and bacterial clearance showed significant differences among the 3 groups (with F values from 10.98 to 770.24, P values below 0.01). The drainage tube blockage rate was significantly lower in groups VSD + IC and VSD + OLI [(2.0 ± 0.4)% and (1.9 ± 0.6)%] than in group VSD [(16.0 ± 1.3)%, with t values respectively 28.77 and 29.20, P values below 0.01]. (3) On PTD 7, the partial pressure values of oxygen of the exudate in groups VSD + IC, VSD + OLI, and VSD were respectively (111 ± 4), (43 ± 4), and (40 ± 4) mmHg (1 mmHg = 0.133 kPa, F = 882.76, P < 0.01). (4) The density of mitochondria in group VSD + OLI was obviously higher than that of the other 2 groups, full in shape, with complete outer membrane and no vacuolization. (5) During debridement, the activity of LDH and SDH in 3 groups showed no significant differences (with F values respectively 0.08 and 1.03, P values above 0.05). On PTD 7, the activity of LDH was lower in group VSD + OLI [(103 ± 15) U/L] than in group VSD + IC [(136 ± 16) U/L, t = 4.49, P < 0.01], while it was higher in group VSD [(155 ± 16) U/L] than in group VSD + IC (t = 2.47, P < 0.05). The activity of SDH was higher in group VSD + OLI [(2.93 ± 0.27) U/L] than that in group VSD + IC [(1.77 ± 0.22) U/L] or group VSD [(1.61 ± 0.19) U/L, with t values respectively 10.21 and 11.65, P values below 0.01]. (6) On PTD 7, there was more positive expression of CD31 in group VSD + OLI than in the other 2 groups. The MVD of groups VSD, VSD + IC, and VSD + OLI were respectively (109 ± 5), (124 ± 5), (141 ± 6) per 400 times visual field (F = 68.78, P < 0.01). (7) The patients in 3 groups mainly received skin or flap grafting as the second stage operation. The survival rates of skin and flap in group VSD + OLI were higher than those of groups VSD + IC and VSD (with t values from 3.32 to 8.26, P < 0.05 or P < 0.01), and the rates were higher in group VSD + IC than in group VSD (with t values respectively 2.67 and 3.18, P values below 0.05).

CONCLUSIONSVSD + OLI is effective in reducing drainage tube blockage, removing necrotic tissue and bacteria, ameliorating ischemia and hypoxia of wound tissue, providing fresh wound bed for wound healing, and improving skin or flap graft survival rates.

Malnutrition of hospitalized patients is a prevailing issue, especially in the perioperative period. As the elderly population increases progressively, surgeons should become more alert to preventing the risk of iatrogenic malnutrition. The consequences of malnutrition, such as delayed wound healing, exposure to infection, pressure sores, gastrointestinal bacterial overgrowth, and compromised immunity can be prevented or attenuated by vigorous nutritional support. Enhanced recovery after surgery is a multimodal perioperative care pathway designed to achieve early recovery for patients undergoing major surgery, in which nutritional intervention is the most important and integral part. Preoperative nutritional assessment, intraoperative considerations against postoperative nutritional problems, and an appropriate postoperative nutritional supply will result in better outcomes of surgery, and, in turn, in reduced postoperative complications, shorter hospital stays, and decreased medical costs. Though enteral nutrition is preferable over parenteral nutrition, parenteral nutrition should be supplemented selectively in those for whom enteral nutrition will inevitably be inadequate.

PURPOSE: This study was done to compare clinical nurses' knowledge and visual differentiation diagnostic ability for the pressure ulcer classification system (PUCS) and incontinence-associated dermatitis (IAD). METHODS: A convenience sample of 602 nurses took the pressure ulcer classification system and incontinence-associated dermatitis knowledge test (PUCS & IAD KT) and completed the visual differentiation tool (VDT), consisting of 21 photographs with clinical information. RESULTS: The overall mean score for correct answers was 14.5 (+/-3.2) in PUCS & IAD KT and 11.15 (+/-4.9) in PUCS & IAD VDT. Incorrect responses were most common for statements related to stage III, IAD for PUCS & IAD KT, and suspected deep tissue injury (SDTI), unstageable, and stage III for PUCS & IAD VDT. Significant correlations were found between PUCS & IAD KT and VDT (r=.48, p<.001). Factors affecting scores for PUCS & IAD VDT were PUCS & IAD KT, frequency of pressure ulcer, IAD management and participation in wound care education programs. CONCLUSION: Results indicate that nurses have an overall understanding of PUCS & IAD, but low visual differentiation ability regarding stage III, SDTI, and unstageable ulcers. Continuing education is needed to further improve knowledge and visual differentiation ability for PUCS & IAD.

Sacrum area is the high-risk area for pressure ulcer to persons with spinal cord injury. A finite element model of the soft tissue in the sacrum area was established to analyze the stress distribution in the soft tissue with the human body lying down. In addition, the muscle oxygenation in the sacrum area was assessed by near-infrared spectroscopy (NIRS) before and after loading pressures. The results showed that the stress was mainly localized in the muscle layer and the stress in the bone-tissue interface was the maximal. When the loading reached 10kPa, the maximal stress in the muscle layer was 15kPa. The muscle oxygenation parameters changed significantly with the applied pressure and returned to normal level after the loading.
