Advances in Three-Dimensional Printing for Craniomaxillofacial Trauma Reconstruction: A Systematic Review.

Craniomaxillofacial (CMF) fractures present significant challenges for plastic surgeons due to their intricate nature. Conventional methods such as autologous bone grafts have limitations, necessitating advancements in reconstructive surgery techniques. This study reviewed the use of three-dimensional printing for CMF trauma reconstruction using human studies. A systematic search of PubMed, EMBASE, and Google Scholar was conducted in February 2024 for case reports, case series, and clinical trials related to CMF trauma reconstruction using three-dimensional printing technology. The authors' systematic review included 20 studies and a total of 170 participants with CMF bone defects. In general, the authors observed low bias risk in analyzed case reports and series, serious bias risk in nonrandomized controlled trials, and moderate bias risk in randomized controlled trials. The printed objects included CMF structure model prototypes, patient-specific implants, and other custom surgical devices. Studies reveal successful outcomes, including restored facial symmetry and function, restored orbital occlusion, resolved enophthalmos and diplopia, achieved cosmetically symmetrical lower face reconstruction, and precise fitting of surgical devices, enhancing patient and surgeon comfort. However, complications such as local infection, implant exposure, and persistent diplopia were reported. Three-dimensional printed devices reduced surgery time but increased preparation time and production costs. In-house production options could mitigate these time and cost expenditures. Three-dimensional printing holds potential in CMF trauma reconstruction, addressing both functional and esthetic restoration. Nevertheless, challenges persist in implementing this advanced technology in resource-limited environments.

Hyperbaric Oxygen Therapy for Diabetic Foot Ulcers Based on Wagner Grading: A Systematic Review and Meta-analysis.

Background: Diabetic foot ulcers (DFUs) are common complications of uncontrolled diabetes mellitus that can result in infection and amputation of the lower extremities. This study compared the benefits and risks of hyperbaric oxygen therapy with those of other DFU treatments, based on the Wagner grading system. Methods: Systematic searches for randomly controlled trials using hyperbaric oxygen therapy for DFUs were performed using PubMed, the Cochrane Library, and Embase. Data regarding demographics, wound healing, minor and major amputations, operative debridement, nonhealing wounds, and adverse effects were analyzed based on Wagner grades, using RevMan 5.4.1 and Microsoft Excel. Results: Hyperbaric oxygen therapy was significantly superior to other treatments for wound healing rates 8 or more weeks after the final treatment (RR = 2.39; 1.87-3.05; P < 0.00001) minor/distal amputations (RR = 0.58; 0.43-0.80; P < 0.007), and major/proximal amputations (RR = 0.31; 0.18-0.52; P < 0.00001) for the 14 studies analyzed. In addition, this therapy increased the rate of complete wound healing for Wagner grades II (RR = 21.11; 3.05-146.03; P = 0.002), III (RR = 19.58; 2.82-135.94, P = 0.003), and IV (RR = 17.53; 2.45-125.44; P = 0.004); decreased the minor/distal amputation rate for grade III (RR = 0.06; 0.01-0.29; P = 0.0004) and the major/proximal amputation rate on for grade IV (RR = 0.08; 0.03-0.25; P < 0.0001); and decreased the operative debridement rate for Wagner grade II (RR = 0.09; 0.01-0.60; P = 0.01). Conclusions: Moderate-quality evidence revealed that adjunctive hyperbaric oxygen therapy improved DFU wound healing for Wagner grades II, III, and IV; prevented minor and major amputations for grades III and IV, respectively; and prevented operative debridement in grade II wounds.

Serum BMP-2 and osteocalcin levels, and CT Hounsfield unit post hyperbaric oxygen therapy in patients with cleft lip and palate post alveolar bone graft: A case study.

Background: This study investigated the levels of bone morphogenetic protein 2 (BMP-2), osteocalcin, and 3D CT Hounsfield units following hyperbaric oxygen therapy (HBOT) in patients with cleft lip and palate (CLP) undergoing alveolar bone grafts to provide a pilot evaluation of the role of HBOT in osteogenesis. Methods: This prospective, quasi-experimental, pre-post-intervention study evaluated seven patients with CLP receiving HBOT after single-stage reconstructions with alveolar bone grafts. The outcomes included the serum levels of BMP-2 and osteocalcin and the 3D CT Hounsfield units obtained before and after the surgery, and after the five HBOT sessions, to a total of 12 measurements. The data were analyzed with linear mixed-effects models using the intervention stage (pre-surgery, pre-HBOT, first to fifth HBOT sessions) as covariates and adjusting for several baseline factors. Results: A significant difference was found in outcome measures across time (ANOVA p < 0.001 for BMP-2 and osteocalcin, p = 0.01 for Hounsfield units), with mean values appearing to steadily increase once HBOT began. Regression analyses indicated that the effect of HBOT was evident in serum osteocalcin after the 1st HBOT session (adjusted b = 1.32; 95% CI 0.39, 2.25) and in serum BMP-2 after the third session (adjusted b = 6.61; 95% CI 1.93, 11.28). After the fifth session, the HBOT effect was fairly pronounced on the two outcomes: the adjusted increase compared to the baseline was 28.06 ng/mL for BMP-2 and 6.27 ng/mL for osteocalcin. Our mixed-effect models also showed a post-HBOT increase in Hounsfield units. Conclusion: We found an increase of BMP-2, osteocalcin, and Hounsfield units following the HBOT intervention. These may suggest an effect of HBOT on osteogenesis.

Evaluation of long-term results following surgical correction of frontoethmoidal encephalomeningocele.

INTRODUCTION: Frontoethmoidal encephalomeningocele (FEEM) is a neural tube defect with herniation of intracranial contents through the anterior skull base at the foramen cecum. Management is surgical and aims to remove the excess meningoencephalocele tissue and perform facial reconstruction. CASE PRESENTATION: We report on two cases of FEEM that presented to our department. A diagnosis based on computed tomography scans revealed a defect in the nasoethmoidal region (case 1), and a defect was found in the nasofrontal bone (case 2). Surgery was performed using a direct incision over the lesion (case 1) and a bicoronal incision (case 2). Treatment in both cases gave a good outcome, and there was no increase in intracranial pressure and neurological deficits. DISCUSSION: The management of FEEM is surgical. Appropriate timing and careful preoperative planning minimize the risks of intraoperative and postoperative complications. Both patients underwent surgery. Different techniques were required in each case, considering a significant difference between the lesion size and the resultant craniofacial deformity. CONCLUSION: Early diagnosis and treatment planning is vital to achieving the best long-term outcome for these patients. In the next stage of patient development, follow-up examination plays a vital role so that further corrective actions can provide a good prognosis.

Adjunctive hyperbaric oxygen therapy with reconstruction of lower eyelid for basal cell carcinoma: A case series.

INTRODUCTION: Basal cell carcinoma (BCC) is among the most widespread non-melanoma skin cancers, with an incidence of around 80 % worldwide. Surgery is the main therapy of choice. High-pressure oxygen is used in hyperbaric oxygen therapy (HBO) to treat hypoxic tissue conditions. By using this technique, the tissue oxygen tensions increase. This is used to treat a wide range of diseases and disorders brought on by hypoxic states, circulation issues, inadequate tissue oxygenation due to vascular damage, tissue damage from infections or accidents, and impairment of tissue healing. CASES PRESENTATION: This paper presents five cases of HBO used in the healing BCC surgery. All patients underwent wide and deep excisions with eight adjunctive sessions of HBO therapy. CLINICAL DISCUSSION: The five cases of post-surgery wound healing improved significantly with HBO. CONCLUSION: BCC is a condition that is frequently identified in the outpatient department. Prerequisites for a better prognosis include early diagnosis based on sound information and prompt, structured, and sufficient therapy. Our study reveals the benefit of HBO in increasing wound healing and preventing complications after surgery for BCC.

Factors related to serum levels of intercellular adhesion molecule-1 in probable COVID-19 patients in surgical treatment: an observational study.

Introduction: COVID-19 causes a systemic inflammatory response, involving dysregulation and misexpression of many inflammatory cytokines. The recruitment and activation of inflammatory cells depend on the expression of many classes of inflammatory mediators, with increased expression of endothelial cell adhesion molecules being related to COVID-19 disease severity. With the World Health Organization having recently updated case definitions to suspect, probable, and confirmed, this study aimed to measure the mean value of intercellular adhesion molecule 1 (ICAM-1) and its relation to suspected COVID-19. Methods: all suspected patients (n=20) were hospitalized and treated following the Indonesian National Guidelines for COVID-19 management. ICAM-1 levels were measured on days 1 and 7, demographic data were recorded, and routine blood count values were measured and additionally considered. Results: the results showed that the levels of ICAM-1 in the 1st-day group (mean 271.3 ng/ml) were higher than those in the 7th-day group (mean 253.9 ng/ml). This difference was statistically significant (p = 0.00, p ≤ 0.05). All of the patients with suspected COVID-19 were included in this study and tested for COVID-19 by reverse transcription polymerase chain reaction (RT-PCR) testing. A total of 10 patients were confirmed positive with a COVID-19 infection, with elevated ICAM-1 levels compared to the confirmed negative patients (with a mean 1st day 296.8 versus a mean 7th day 279.0 ng/ml). ICAM-1 levels of all patients decreased by the seventh day. Conclusion: the mean value of ICAM-1 levels for patients with confirmed positive COVID-19 cases was higher than those with suspected COVID-19 cases.

Hyperbaric oxygen therapy in low extremity trauma: A case series.

Introduction: Trauma to the extremities is a common major health problem that requires special attention because it can have a dangerous impact on both the viability of the limb and the patient's life. Hyperbaric oxygen therapy is an alternative therapy hypothesized to improve the prognosis in lower extremity trauma. Case presentation: We present a series of 7 cases of lower extremity trauma treated with hyperbaric oxygen therapy: soft tissue loss, neglected chronic burn injury, high-voltage electrical burn, gas gangrene, crush injury, chemical burn, and excoriation with skin loss. Discussion: Hyperbaric oxygen therapy involves giving 100% oxygen in a chamber at pressures above atmospheric pressure (2-3 atm absolute [ATA]). It can increase oxygen delivery to peripheral tissues with vascular compromise, cytogenic and vasogenic edema, and cellular hypoxia caused by limb trauma. Conclusion: Hyperbaric oxygen therapy has many benefits in lower extremity trauma for wound recovery, preventing complications, and helping patients return to daily activities.

Massive recurrent epistaxis in traumatic pseudoaneurysm of sphenopalatine artery: Report of 2 cases.

Massive recurrent epistaxis because of traumatic pseudoaneurysm of the sphenopalatine artery is rarely diagnosed. It is formed by partial rupture of the endothelium by facial trauma and managed with embolization and maxillofacial reconstruction. Here, we report a case of 2 massive recurrent epistaxes and 1 case of carotid cavernous fistula, which needed embolization to control the recurrent bleeding following trauma. Epistaxis is first managed by tampon, then referred as needed for endovascular intervention by sphenopalatine artery embolization and followed by maxillofacial reconstruction. Recurrent epistaxis was successfully treated with endovascular embolization.

Bactericidal effect of hyperbaric oxygen therapy in burn injuries.

INTRODUCTION: Burn injuries are frequently encountered in emergency cases and often become the port of entry for pathogens. More than 450,000 burn injuries occur annually causing nearly 3,400 deaths in the United States. The prevalence of burn injury in Indonesia is 0.7% in 2013. More than half of these According to several studies on the use of patients were treated for bacterial infections, some of which were resistant to certain antibiotics. Using hyperbaric oxygen therapy (HBOT) to treat burns has several positive effects including managing bacterial infections, as well as accelerating the wound healing process. Therefore, this study aims to prove the effectiveness of HBOT in inhibiting bacterial growth. METHODS: This is an experimental research study in rabbits using a post-test control group design. 38 rabbits were given second-degree burns on the shoulder region with a metal iron plate that has been previously heated for 3 min. Bacterial cultures were taken on days 5 and 10 after exposure to the burns. The samples were divided into two groups, HBOT and control. Statistical analyses were performed using the Mann-Whitney U method. RESULTS: Gram-negative bacteria were the most frequently found pathogen in both groups. Citrobacter freundi was the most common Gram-negative bacteria (34%) found in the culture results of both groups.In contrast to the control group, there was no bacterial growth found in the HBOT group's culture results, (0%) vs (58%). A significant reduction of bacterial growth was observed in the HBOT group (69%) compared with the control group (5%). Bacterial levels stagnated in 6 rabbits (31%) in the HBOT group and 7 rabbits (37%) in the control group. Overall, there was significantly less bacterial growth in the HBOT treatment group compared with the control group (p < 0.001). CONCLUSION: HBOT administration can significantly reduce bacterial growth in burn injuries.

Hyperbaric Oxygen Therapy in Managing Minimally Invasive Aesthetic Procedure Complications: A Report of Three Cases.

INTRODUCTION: Minimally invasive aesthetic procedures such as filler injections and thread lifts have gained popularity recently. Complications from these aesthetic procedures are difficult to avoid. This increasing public health concern requires a combination of effective therapeutic modalities. Hyperbaric oxygen therapy (HBOT) has generated favorable results in treating a diversity of wounds, inflammation, and infection. CASE PRESENTATIONS: Three cases with complications arising from aesthetic procedures were described in this report. The patients were all female, with ages ranging from the late-twenties to mid-fifties. Two patients experienced complications from filler injections, one of which progressed to a parotid gland infection due to a placental extract filler while the other was caused by a hyaluronic acid filler. The third patient had notable excoriations and inflammation on both cheeks following a thread lift procedure. Alongside antibiotics and other symptomatic therapies, the patients received multiple, 90-minute HBOT sessions at 2.4 ATA over the course of one to two weeks. The wounds were frequently monitored to evaluate the healing progress. DISCUSSION: Complications from facial rejuvenation procedures can be disastrous. They expose the patient to the risk of developing vascular occlusions and skin infections that require prompt and effective treatment. Multiple treatment options (eg, frequently massaging the affected area, warm compresses, aspirin, and antibiotics) have been used to treat these complications. HBOT serves a valuable purpose in restoring adequate tissue perfusion in cases of filler-induced vascular occlusion and infection. Moreover, HBOT assists in restoring tissue injury and reducing inflammation following thread lift procedures. CONCLUSION: HBOT has proven helpful as a treatment adjunct toward counteracting the effects of minimally invasive aesthetic procedures in several cosmetic-related cases.

Fostering a faster post-operative wound healing process with hyperbaric oxygen therapy in a rare case of squamous odontogenic tumor.

INTRODUCTION: The surgical removal of an intraoral tumor and preventing intraoral wound dehiscence are constant challenges faced by surgeons today. Hyperbaric oxygen therapy (HBOT), the inhalation of 100% oxygen at a greater atmospheric pressure, is often used in cases of wounds to induce a faster wound healing process, alongside other treatment modalities. We report a rare case of squamous odontogenic tumor (SOT) treated with HBOT after being surgically removed to foster an accelerated wound recovery. CASE PRESENTATION: A 39-year-old Asian male presented with an intraoral 3 × 4 cm tumor, accompanied by acute pain on the maxillary region. Biopsy results showed a solid, brown parenchyma with islands of mature squamous epithelial cells, confirming the diagnosis of an SOT. An intraoral surgical approach was performed to remove the tumor. The patient was then treated with prophylactic antibiotics and 5 consecutive, daily sessions of HBOT at 2.0 ATA as an adjuvant therapy. No further complaints and no abnormalities were found at the 2-week follow-up evaluation. DISCUSSION: In our case of SOT, HBOT plays a role to inhibiting the bacterial growth which could lead to post-operative wound infections. A number of studies have incorporated HBOT as an adjuvant therapy for post-operative intra oral wounds which has resulted in minimal wound complications. CONCLUSION: The use of HBOT as an adjunctive therapy in managing possible wound complications after the resection of an intraoral tumor enables a faster angiogenesis process, reduces tissue hypoxia and minimizes the risk of post-operative wound infections; hence fostering the wound healing process.

Correlation analysis of HIF-1α and Ca15-3 in response to neoadjuvant chemotherapy in locally advanced breast cancer: A cohort study in Indonesia.

BACKGROUND: Breast cancer (BC) is the most common cancer among women worldwide and a leading cause of death in Indonesia. The primary treatment of locally advanced BC is neoadjuvant chemotherapy (NAC). The rapid proliferation of tumor cells in a neoplastic microenvironment is largely due to hypoxia, which also encourages the development of chemoresistant BC. The master regulator of the hypoxia response is hypoxia-inducible factor-1α (HIF-1α). The response evaluation criteria in solid tumors (RECIST) is an objective response metric that demonstrates the efficacy of a NAC based mostly on the size of the tumor. Ca15-3 is the protein product of the MUC1 gene and is the most widely used serum marker in BC. The purpose of this study is to investigate the relationship between HIF-1α and RECIST and between Ca15-3 and RECIST and to assess the relationship among all of them in BC. METHODS: This observational study used the prospective cohort method included 11 patients with histopathologically confirmed BC, specifically invasive ductal carcinoma. We evaluated the changes in HIF-1α and Ca15-3 serum levels using ELISA and measured tumor lesions with RECIST. The procedure was carried out twice. Serum levels were measured at baseline, and after receiving two cycles of NAC (5 weeks). RESULTS: Among the 11 patients included in this study, HIF-1α, Ca15-3, and RECIST decreased significantly after NAC. The changes in RECIST correlated with Ca15-3: each unit decrease in RECIST score was associated with a 0.3-unit decrease in Ca15-3 levels (p = 0.019). CONCLUSIONS: There was a decrease in HIF-1α, followed by a decrease in Ca15-3 and RECIST in response to chemotherapy. There was a statistically significant correlation between Ca15-3 and response to chemotherapy. This study evidences the relationship between factors that shape the local tumor microenvironment.

Cutaneous angiosarcoma: A case report.

INTRODUCTION: Angiosarcoma is a very rare malignancy, which varies based on the location and organ affected. A clinicopathological form of cutaneous angiosarcoma (CAS) involves the head: scalp, face, and neck. We report a 59-year-old female patient with CAS on the temporoparietal region of the scalp. CASE PRESENTATION: The patient presented with lesions in the head area, which appeared suddenly in the last 6 months, (before her surgery). Excision was performed under general anesthesia for bleeding as indicated on the right temporal region. The excision procedure was carried out three times at various stages, and then closed with skin grafts. Pathological examination of the three excised tissues showed progression, leading to CAS. Based on the clinical picture and anatomical assessment, a consultation with the surgical oncology department was necessary for further treatment. DISCUSSION: Angiosarcoma has a high rate of progression. The onset of lesions, which are difficult to detect, does not often lead to progression. Other macroscopic features appear as bluish macules, which can be perceived as bruising. Wide surgical resection is the optimal treatment and is usually combined with radiotherapy and/or chemotherapy. This patient underwent gradual excision, based on bleeding in the right temporal lesion, along with progressive pain. CONCLUSION: Surgical is the preferred management for our patients. Determination of multimodality therapy as treatment for CAS requires assessment of all factors related to age and patient condition. Follow-up evaluation is carried out after palliative therapy - to observe the general condition of the patient, tumor progression, tendency for metastases, and excision of any remaining lesions.

Post-skin incision scar tissue assessment using patient and observer scar assessment scales: A randomised controlled trial.

BACKGROUND: The scalpel was once the gold standard for surgical incisions. Electrosurgery has started to supplant scalpels but is not yet acceptable for skin incisions due to the risk of burns and deeper injury relative to the scalpels' neat incision with less tissue damage. The unnecessary burden of excessive scar formation makes comparing these two methods challenging. Therefore, this study aims to compare post-incision skin scarring created after monopolar electrosurgery and scalpel surgery, and evaluate the Patient and Observer Scar Assessment Scale (POSAS) suitability for assessing skin incision scars by comparing patients' and observers' scores. METHODS: This self-controlled study involved patients undergoing elective and emergency skin surgery procedures. A singular wound site was created using two incision methods (monopolar electrosurgery and scalpel) simultaneously. Post-incision scar tissue formation was evaluated using the POSAS, a subjective scar assessment tool that involved patients self-reporting on pain, itching, color, thickness flexibility, and surface relief. Observer-rated vascularity, pigmentation, thickness, flexibility, and surface relief both using a 5-point Likert-type scale. We performed this assessment three months post-surgery, and the results were analyzed by a battery of statistical tests and linear mixed models. RESULTS: Twenty patients were included in this study. Data analyzed using the paired t-test or Wilcoxon rank-sum test indicated no statistically significant differences between the scar tissue created by monopolar electrosurgery and scalpels according to both the patients and the observers. Correlation analyses between the patients' and observers' total POSAS scores indicated these followed a moderate linear relationship (r = 0.51; p < 0.001). Linear mixed models further supported the agreement of POSAS total scores between patients and observers. They also confirmed that electrosurgery was not inferior to the scalpel technique. CONCLUSION: Scar tissue from skin incisions made by monopolar electrosurgery were indistinguishable from those created with a scalpel. The POSAS instrument is an acceptable means of assessing scar formation on the skin.

Predicting hyperbaric oxygen therapy success using the decision tree approach.

INTRODUCTION: Hyperbaric oxygen therapy (HBOT), a procedure that involves the patient inhaling 100% oxygen gas under pressure, is currently used as an adjunctive treatment option for certain inflammatory conditions. HBOT can improve wound healing by increasing the rate of angiogenesis in injured tissue by increasing levels of vascular endothelial growth factor (VEGF). VEGF causes re-epithelialization, the migration of endothelial cells, and the formation of granulation tissue, which are involved in the wound healing process. METHODS: This study contains secondary data analyses of information previously collected in two separate studies, each concerning the effects of HBOT on diabetic foot ulcers and crush injury fractures at Prof. Dr. R. D. Kandou Hospital Manado and Siloam Hospital Manado from 2019 to early 2020. RESULTS: Based on the classification tree analysis, the predictors of HBOT success were leukocytes level (34%), platelet count (32%), and age (26%). The conditional inference tree analysis also indicated significant leukocyte levels, age, and platelet counts (p < 0.001), with which the interpretation of these results was the same as the classification tree analysis method. The results obtained from the random forest analysis revealed that the mean value of Gini reduction for leukocytes (207.3), platelets (110.2), age (97.9), and hemoglobin (57.9) can be used as indicators of successful HBOT. These three methods support that age, leukocytes, and platelets are determinants of HBOT success, while hemoglobin levels were only significant in one analysis method. Therefore, a new, proposed algorithm containing these factors was assembled from the results of this study. CONCLUSION: HBOT cannot be separated from specific variables that contribute to and can predict its success.

Expanding pneumocephalus due to craniofacial fractures: A case report.

INTRODUCTION: Pneumocephalus (PNC) is the presence of air in the intracranial cavity. The most frequent cause is craniofacial trauma, though there are many etiologies, including surgical procedures. PNC with compression of the frontal lobes and widening of the interhemispheric space between the tips of the frontal lobes results in the characteristic radiological finding of the "Mount Fuji sign". PRESENTATION OF CASE: A 57-year-old man presented to the A&E with loss of consciousness due to a motorcycle collision 9 h prior. He had a GCS of E4M6V5, and a head CT scan revealed minimal PNC forming in both hemispheres. After discharge, severe headaches and rhinorrhea developed. A second CT scan revealed a massive PNC. An operation was then performed via a bicoronal incision to drain the PNC and seal the cranial defect. A burr hole in the calvarium was created, and the cranial defect was closed using a pericranial rotational flap. Post-operation, the patient's headache and rhinorrhea decreased; neither symptom was present at 1-month post-operation. The wounds healed with minimal scarring, and the cosmetic outcome for the craniofacial fracture was acceptable. DISCUSSION: Although the patient may at first present with a mild head injury, this can progress into something much more serious. PNC is difficult to diagnose clinically. Rarely, patients describe a splashing sound upon moving the head (termed bruit hydro-aerique), which can also be auscultated. A head CT scan is the gold standard in the diagnosis of PNC. Pericranial flaps are widely used for dural repair because they are easily accessible and have a lower rate of infection than artificial grafts on expanding PNC. CONCLUSION: Tension PNC may be slow-growing and increase intracranial pressure to high levels before clinical signs are present. The pericranial rotational flap technique is the best way to close a dura mater defect in cranial base fractures with tension PNC.

Trichilemmal carcinoma in an unexposed area of the nose: A case report.

INTRODUCTION: Trichilemmal carcinoma (TC) is a rare, low-grade, cutaneous malignant lesion that originates from hair follicle cells. It usually occurs in photo-exposed areas, especially on the face, scalp, neck, and dorsal part of the hand. We report a case of an adult female with TC in an unexposed area of the nose, which completely obstructed the right nasal cavity. CASE PRESENTATION: An 82-year-old female presented with TC in a non-sun-exposed area of the nasal cavity, which grew progressively over one year and caused nasal obstruction. The mass had dimensions of 15cm × 8cm, and it was removed surgically with a wide and deep excision. Histopathological examination confirmed the diagnosis of TC. A follow-up at three years post-surgery revealed no signs of recurrence. CONCLUSION: Surgical excision with wide margins improved the treatment outcome by preventing local recurrence and providing satisfying cosmetic results.

ICAM-1 levels in patients with covid-19 with diabetic foot ulcers: A prospective study in southeast asia.

BACKGROUND: Viral infection can compound the severity of pre-existing inflammation caused by underlying diseases. For those with a chronic, immune-related condition such as diabetic foot ulcers (DFUs), the coronavirus disease (COVID-19) serves to exacerbate the inflammatory burden. Serum levels of intracellular adhesion molecule-1 (ICAM-1), a primary mediator of cell adhesion express in the inflammatory process, are often used to indicate the gravity of all inflammatory conditions. Therefore, the purpose of this study was to investigate serum ICAM-1 levels before and after debridement in patients with DFUs who were also diagnosed as COVID-19 positive compared with those who were COVID-19 negative. METHODS: 20 patients with DFUs were screened for COVID-19 and then divided into COVID-19 positive and negative groups according to the results. Before debridement, chest x-rays and blood analysis, including ICAM-1 serum levels, were performed in both groups. Only ICAM-1 serum levels were measured after debridement. RESULTS: Of the 20 patients included in this study, 55% were male (n = 11) and 45% were female (n = 9). The mean age was 52.9 ± 1.9 years. ICAM-1 levels in patients with DFU in the COVID-19-positive group were significantly higher than those in the COVID-19-negative group (median 317.2 vs 149.2, respectively; p < 0.001). Serum levels of ICAM-1 reduced significantly in patients with DFU in the COVID-19-positive group were significantly higher than those in the COVID-19-negative group after debridement (median 312.5 vs 130.3; p < 0.001). CONCLUSION: ICAM-1 serum levels represent an additional, initial screening marker for COVID-19.

Effects of hyperbaric oxygen therapy on the healing of thermal burns and its relationship with ICAM-1: A case-control study.

BACKGROUND: The damaging effects of thermal burns need to be managed holistically in order to create a suitable environment for wound healing. The purpose of our study was to investigate the effects of hyperbaric oxygen therapy (HBOT) on the healing of thermal burns and its relationship with intercellular adhesion molecule 1 (ICAM-1). METHODS: Twenty patients with thermal burns were randomly divided into two groups: the group to receive HBOT and the control group. Levels of the ICAM-1 mRNA gene and ICAM-1 serum along with the degree of wound epithelialization were examined before and after treatment. Laboratory and physical findings between the groups were compared. RESULTS: In the HBOT group compared with the control group, thermal wound complications were significantly reduced (p = .006), while length of stay in hospital was substantially reduced (p = .001). ICAM-1 serum levels strongly correlated with ICAM-1 mRNA gene expression (R 2 = 0.909, p < .001). The expression of the ICAM-1 mRNA gene (12.32 ± 1.31 vs. 10.79 ± 1.38) and ICAM-1 serum level (231.46 ± 37.20 vs. 158.23 ± 68.30) in patients with at least a 50% burn area exceeded those of patients with a smaller burn area. HBOT significantly decreased (p < .05) the expression of the ICAM-1 mRNA gene and ICAM-1 serum level (p = .004). The number of HBOT sessions strongly correlated with ICAM-1 serum level (p = .043) but poorly correlated with ICAM-1 mRNA gene expression (p = .22). The expression of the gene, however, strongly correlated with ICAM-1 serum level (r = -0.988, p < .001). CONCLUSION: HBOT can reduce thermal wound complications, length of stay in hospitals due to thermal burns, ICAM-1 mRNA gene expression, and ICAM-1 serum level.

Hyperbaric Oxygen Therapy for Reconstructive Urology Wounds: A Case Series.

INTRODUCTION: Hyperbaric oxygen therapy (HBOT) has been applied to urological wound healing because it reduces inflammation, facilitates angiogenesis through endothelial proliferation, stimulates fibroblast, lymphocyte, and macrophage activity, and exerts bactericidal effects. Thus, we present a case series of reconstructive urology wounds treated adjunctively with HBOT. CASE REPORT: Here, we present the cases of eight patients with urology wounds who underwent different forms of surgical reconstruction. Three patients received penile shaft silicone fluid injection with repeated infection, successful excision of a siliconoma mass, and defect closure with a full-thickness skin graft. One patient had hypospadias and multiple post-closure fistulae. Two patients had bilateral keystone flaps (post total penectomy, orchidectomy, perineotomy, and penile tumors) closed with a split-thickness skin graft (STSG). Two patients had Fournier's gangrene in their genital area, for which the wound was debrided and then closed with a STSG. All patients received HBOT after surgery with satisfying results. CONCLUSION: HBOT promotes wound healing and improves graft integration in patients undergoing urological reconstructive surgery.
