RESUMEN
Chronic, open, non-healing wounds pose a continual challenge in medicine as the treatment is variable and there are no documented consistent responses. Although wound aetiologies vary and there are a number of factors that affect chronic wound pathogenesis, wound ischaemia and bacterial colonisation of wounds are the chief concerns among them. Conventionally, pulse lavage has been used primarily as a wound debriding device. To address both the critical factors of wound ischaemia and bacterial burden, a couple of technical points were proposed and applied in this study. The objective of our study was to evaluate pulse lavage therapy's ability to improve the healing rate of chronic wounds compared to that of the traditional saline-wet-to-moist dressings. The study period was from 1 August 2010 to 31 January 2012 and was conducted in our institution. Thirty patients with 31 chronic, non-healing wounds were enrolled in the study after obtaining proper consent. Subjects were randomised (15 patients each) to the pulse lavage group and the control group. Patients in the test group were subjected to irrigation of their wounds with pulsed lavage at 10 to 15 psi pressure. In the control group, wound was closed by applying moist betadine saline gauze dressings after cleaning with saline. Wounds treated with pulse lavage system significantly reduced in size, had better control of bacterial contamination and had overall faster healing rates. Efficacy of pulse lavage can be increased by correct method of administration of the irrigant.

Physicians struggle to retrieve data from electronic medical records. We evaluated a digital tool that enhances physician efficiency in retrieving and analyzing patient information for treatment decision-making. Our use case is the care of diabetic patients. Evaluation results showed that healthcare providers who used the i4C (Insights for Care) dashboard experienced greater time efficiency than those who used traditional EMR information retrieval methods. A comprehensive evaluation of the i4C Dashboard confirms its effectiveness in facilitating diabetic care data management, as well as its potential application to a wide range of healthcare scenarios. In order to further maximize its effectiveness on clinical efficiency and patient care, future research should focus on improving its usability and scalability.

INTRODUCTION: Mitochondrial LonP1 is an ATP-powered protease that also functions as an ATP-dependent chaperone. LonP1 plays a pivotal role in regulating mitochondrial proteostasis, metabolism and cell stress responses. Cancer cells exploit the functions of LonP1 to combat oncogenic stressors such as hypoxia, proteotoxicity, and oxidative stress, and to reprogram energy metabolism enabling cancer cell proliferation, chemoresistance, and metastasis. AREAS COVERED: LonP1 has emerged as a potential target for anti-cancer therapeutics. We review how cytoprotective functions of LonP1 can be leveraged by cancer cells to support oncogenic growth, proliferation, and survival. We also offer insights into small molecule inhibitors that target LonP1 by two distinct mechanisms: competitive inhibition of its protease activity and allosteric inhibition of its ATPase activity, both of which are crucial for its protease and chaperone functions. EXPERT OPINION: We highlight advantages of identifying specific, high-affinity allosteric inhibitors blocking the ATPase activity of LonP1. The future discovery of such inhibitors has potential application either alone or in conjunction with other anticancer agents, presenting an innovative approach and target for cancer therapeutics.

Objective : Palatal fistulas are not uncommon after palatoplasty. Although there are currently many techniques that can be used to close large palatal fistulae, most of these procedures are usually cumbersome and mostly unreliable with high recurrence rates. The facial artery musculomucosal (FAMM) flap was described to circumvent these problems. The purpose of this study was to review our experience with the FAMM flap to reconstruct palatal fistulas, most of them being recurrent. Materials and Methods : A retrospective analysis was done of 11 FAMM flaps performed between January 2007 and March 2012. Results : There were no major complications. Venous congestion was seen in two cases. Two flaps developed terminal marginal necrosis. One patient had suture line dehiscence. There were no recurrences of the fistula after repair. All patients had a satisfactory closure of the fistula. Conclusion : FAMM flap is a reliable and versatile flap that provides like with the like tissue and is a good option for closure of recurrent wide palatal fistulae.

The soft tissue tumor lipoma is quite frequent. Although it is the most mesenchymal tumor of the trunk and proximal regions of the extremities, it is quite uncommon to find it on the oral mucosa, accounting for just 1% to 5% of benign oral tumors. There is no specific location that is more prone to lipoma development in the mouth. Some frequent sites are the tongue, buccal mucosa, and the mouth's floor. A Yellowish mass with no symptoms is the normal clinical appearance. In most cases, the overlaying epithelium is unharmed, and superficial blood vessels may be seen passing through and around the tumor. The differential diagnosis might also include granular cell tumors, neurofibroma, traumatic fibroma, and diseases of the salivary glands (mucocele and mixed tumor). Herein a detailed case of a 28-year-old woman with a right-sided lower-lip oral lipoma is presented in this paper.
RESUMEN
OBJECTIVES: Long-term durability of bioprosthetic heart valves (BPs) are limited by structural valve degeneration (SVD) leading to stenosis and/or regurgitation. In this study, we sought to determine the metabolic markers associated with SVD. METHODS: In a cohort of 220 patients with an aortic BP (mean follow-up of 2.5 ± 1.2 years), we compared the metabolic and blood lipid profile including the levels of adiponectin and the proportion of small, dense low-density lipoprotein (LDL) particles (%LDL(<)(255Å)) in individuals developing echocardiographic evidence of early BP hemodynamic dysfunction with subjects having no features of BP dysfunction. RESULTS: Patients developing BP dysfunction (n = 69; 31.3%) had a tendency of higher triglyceride levels. Moreover, patients with BP dysfunction had an increased proportion of %LDL(<)(255Å). In multivariate linear regression analysis, after adjustment for age, gender, BP size and hypertension, the %LDL(<)(255Å) (p = 0.04) was significantly associated with BP dysfunction. In addition, patients with an elevated level of %LDL(<)(255Å) along with a decreased plasma adiponectin level were at a very high risk of developing early BP hemodynamic dysfunction (OR = 2.54, p = 0.04). CONCLUSION: BP dysfunction is significantly associated with an increased proportion of small, dense LDL.

INTRODUCTION: Diabetic foot ulcers (DFUs) are a global burden on health care systems. Despite the availability of various treatment modalities, many DFUs do not heal. Nonhealing wounds can lead to various complications, which add to significant morbidity in terms of the degree of moisture retained in the dressing, pain, foul order, and restriction of daily activities. A different treatment modality that can promote the wound healing process earlier (and is cost-effective, easy to use, and readily available) may be necessary to consider. OBJECTIVE: The purpose of the current study was to demonstrate the efficacy of ultrathin skin grafting (UTSG) in the early healing of DFUs in terms of cost-effectiveness, reduced total number of hospital visits, and final wound outcome (ie, limb salvage rate). MATERIALS AND METHODS: A randomized controlled trial was conducted in which 52 patients were treated with either UTSG (test group) or conventional dressing (control group). Both groups were compared by time to healing, number of hospital visits, cost, and final outcome of the wound. RESULTS: By the end of the 12-week study period, 84.61% of wounds managed with UTSG healed completely, whereas only 53.84% of wounds managed with conventional methods achieved complete healing. The test group achieved a more than 50% wound size reduction within 6 weeks after grafting. There were fewer hospital visits for the test group, indicating this grafting technique was more cost-effective than the control group. CONCLUSIONS: As demonstrated in this study, UTSG appears to be beneficial in achieving faster healing of DFUs and improving the final outcome of the wound.

Background: Most patients with COVID-19 experience mild illness which can be managed in a home environment. This study was done to assess the perception, awareness and practices regarding home-based management of COVID-19 among the general population in India. Methods: This cross-sectional study was done in May and June 2021. Data were collected using a Google Form. Results: Mean age of the 294 participants was 36.6 ± 12.1 years. Of these participants, 45 (15.3%) were diagnosed with COVID-19 anytime in the past. Among them, 37 (82.2%) underwent home-based management for COVID-19. Monitoring of body temperature and oxygen saturation was performed just once a day by 15.2% and 5.9% of COVID-19 patients respectively. Self-medication was practiced by 11 (29.7%) patients. Disposable face masks were worn by 23 (62.2%) patients beyond eight hours of continuous usage. The disposable type of face mask was not discarded despite becoming wet and cloth masks were worn by eight (21.6%) patients. Disposable gloves were only worn by 14 (37.8%) care providers of COVID-19 patients. As many as 10 (27%) patients were tested for COVID-19 after completion of home isolation. Awareness of all mild symptoms and signs of the disease were known to only 19 (6.5%) participants. Normal oxygen saturation in the blood was known to 40 (13.6%) participants. Just six (2%) participants were aware of the correct duration of home isolation in a symptomatic patient with COVID-19. The recommended duration of hand washing with soap and water was known to 102 (34.7%) participants. As many as 17.4% and 32.7% participants were not confident in using thermometer and pulse oximeter respectively. Conclusion: Practices, awareness and perception regarding certain essential measures in COVID-19 home management were found lacking among a number of participants. These need to be addressed by suitable training programs among the general population.

INTRODUCTION: Oral lichen planus (OLP) is a condition frequently referred to the specialist dental clinic for diagnosis and management. It is a disease of the skin and mucous membranes with oral manifestations too. It varies in appearance from keratotic to erythematous and ulcerative form. Immunosuppressants are frequently used for patients but some of these drugs could be implicated in malignant transformation, thus there is a clear need to find an alternative therapy for OLP. AIM: To evaluate the relief of symptoms and reduction in the size of the lesions of lichen planus with 0.2% hyaluronic acid topical application and to compare the efficacy of topical hyaluronic acid (0.2%) with that of patients on placebo. MATERIALS AND METHODS: A randomized controlled study was conducted on 50 symptomatic and biopsy proven patients with lichen planus. The subjective symptoms like Visual Analogue Scale (VAS) and the objective symptoms like degree of erythema and mean area of the lesion were recorded preoperatively and on day 7, day 14, day 21 and day 28. The selected patients were divided randomly into group-I comprising of 25 patients who received topical 0.2% hyaluronic acid therapy for 14 days and group-II comprising of 25 patients who received topical application of placebo for 14 days. The statistical tests used were Mann-Whitney U test, t-test, Wilcoxon matched pairs test by ranks and paired t-test. RESULTS: Symptomatic effect of soreness evaluation- there was a significant reduction in VAS scores in the test group as compared to placebo, similarly there was also significant reduction in the degree of erythema, change in the size of the lesion and area of the lesion in the test group. There was significant improvement in relief of symptoms, in the degree of erythema and mean area of the lesion in Group-I when compared with group-II. CONCLUSION: Topical application of 0.2% Hyaluronic acid showed a significant clinical response when compared to topical placebo. It is easy to use; hence a frequent application scheme should be advised to improve the efficacy of hyaluronic acid.
RESUMEN
Dowling-Degos disease (DDD) is a rare autosomal dominant condition characterized by multiple, small, round pigmented macules usually arranged in reticular pattern, chiefly distributed in axillae and groins. Here we are reporting three atypical cases of DDD in a family. They had hypopigmented macules with typical features of DDD indicating generalized DDD. Histopathology confirmed the diagnosis. We present these three cases to stress the existence of generalized DDD phenotype in the Indian population.
RESUMEN
Owing to the increased use of the axillary artery for arterial inflow during cardiopulmonary bypass, patients with previous cannulation at this site who require reoperation will be encountered more and more frequently. We describe the cases of 2 patients who required recannulation of the axillary artery for complex reoperations of the thoracic aorta. The technique and pitfalls are described. The decision was made to reuse the previous cannulation site at the right axillary artery due to the presence of large pseudoaneurysms in proximity to the sternum. The old 8-mm Dacron stump was found and excised, and a new 8-mm Dacron graft was sutured to the right axillary artery for arterial inflow. In the 1st patient, the Dacron side-graft enabled insertion and subsequent inflation of an EndoClamp within the Dacron graft of the ascending aorta, which obviated profound hypothermia. In the 2nd patient, recannulation of the right axillary artery enabled us to open the sternum at low flow using moderate hypothermia, given that antegrade cerebral perfusion was easily accessible in the event of a more prolonged arrest time. Both patients recovered fully, without neurovascular complications secondary to the recannulation of the right axillary. Recannulation of the right axillary artery is safe during complex reoperation of the thoracic aorta. It avoids retrograde perfusion in the often-diseased descending thoracic aorta. Furthermore, sternal reentry may be performed under moderate hypothermia, because antegrade cerebral perfusion can be initiated with ease.

A middle-aged male presenting with complaint of progressively increasing dysphagia was found to have a large cystic mass lesion in the middle mediastinum on evaluation. A diagnosis of an endo-duplication cyst was considered after exploration, in view of infiltration of the muscular layer of the lower thoracic esophagus, presence of multiple hyperemic nodular lesions on its inner surface and its location in the middle mediastinum. However, the histopathology revealed the lesion to be a cystic lymphangioma.

Klippel-Trenaunay syndrome is a well-known conglomeration of capillary malformations, bony or soft tissue hypertrophy, and abnormal deep or superficial veins. Although it generally presents with grossly enlarged limbs, it can present with more serious features like haematuria, haematochezia, and seizures. This retrospective study included patients admitted with the diagnosis of Klippel-Trenaunay syndrome in this institute from 2001-2010. The patients' demographic data, clinical features, associated findings, and treatments given were tabulated. A total of 19 patients were included in the study. Two patients presented with haematocezia and had to undergo bowel resection. Five presented with bleeding and ulceration. Debulking surgery was done in three of them. Patients also presented with abdominal distension, jaundice, seizures, and haematuria. Although the common presentation of varicose veins was treated with sclerotherapy, the treatment was tailored to each patient. Klippel-Trenaunay syndrome is a multifaceted disorder which can manifest in a number of different ways. These features may be missed by an unwary plastic surgeon treating them only for the limb hypertrophy.

CONTEXT: Wound measurement is an important aspect of wound management. Though there are many techniques to measure wounds, most of them are either cumbersome or too expensive. AIMS: To introduce a simple and accurate technique by which wounds can be accurately measured. SETTINGS AND DESIGN: This is a comparative study of 10 patients whose wounds were measured by three techniques, i.e. ruler, graph and our technique. MATERIALS AND METHODS: The graph method was taken as the control measurement. The extent of deviation in wound measurements with our method was compared with the standard technique. The statistical analysis used was ANOVA. RESULTS: The ruler method was highly inaccurate and overestimated the wound size by nearly 50%. Our technique remained consistent and accurate with the percentage of over or underestimation being 2-4% in comparison with the graph method. CONCLUSIONS: This technique is simple and accurate and is an inexpensive and non-invasive method to accurately measure wounds.
RESUMEN
INTRODUCTION: Split-thickness skin grafting (SSG) is a technique used extensively in the care of burn patients and is fraught with suboptimal graft take when there is a less-than-ideal graft bed and/or grafting conditions. The technique of Negative Pressure Dressing (NPD), initially used for better wound healing has been tried on skin-grafts and has shown to increase the graft take rates. However, comparative studies between the conventional dressing and vacuum assisted closure on skin grafts in burn patients are unavailable. The present study was undertaken to find out if NPD improves graft take as compared to conventional dressing in burns patients. MATERIALS AND METHODS: Consecutive burn patients undergoing split-skin grafting were randomized to receive either a conventional dressing consisting of Vaseline gauze and cotton pads or to have a NPD of 80 mm Hg for four days over the freshly laid SSG. The results in terms of amount of graft take, duration of dressings for the grafted area and the cost of treatment of wound were compared between the two groups. RESULTS: A total of 40 split-skin grafts were put on 30 patients. The grafted wounds included acute and chronic burns wounds and surgically created raw areas during burn reconstruction. Twenty-one of them received NPD and 19 served as controls. Patient profiles and average size of the grafts were comparable between the two groups. The vacuum closure assembly was well tolerated by all patients. Final graft take at nine days in the study group ranged from 90 to 100 per cent with an average of 96.7 per cent (SD: 3.55). The control group showed a graft take ranging between 70 and 100 percent with an average graft take of 87.5 percent (SD: 8.73). Mean duration of continued dressings on the grafted area was 8 days in cases (SD: 1.48) and 11 days in controls (SD: 2.2) after surgery. Each of these differences was found to be statistically significant (p<0.001). CONCLUSION: Negative pressure dressing improves graft take in burns patients and can particularly be considered when wound bed and grafting conditions seem less-than-ideal. The negative pressure can also be effectively assembled using locally available materials thus significantly reducing the cost of treatment.
