RESUMO

BACKGROUND: Chronic wounds are prevalent globally at endemic proportions. The common features associated with chronic wounds are prolonged inflammatory phase, infection with multidrug-resistant (MDR) bacteria, and subsequent biofilm formation. The present randomized-controlled trial (RCT) study was undertaken on chronic wounds of ≥6 weeks longer duration using customized phages to evaluate the efficacy and safety of bacteriophage therapy. METHODS: The study was conducted from December 2021 to August 2023. Thirty patients in each of the arms (placebo and bacteriophage) were recruited with chronic wounds. The patients, both arms, received the conventional treatment of wound debridement, local antiseptics, and local and systemic antibiotics at the discretion of the treating surgeon. However, before applying the customized bacteriophage cocktail or placebo, the wound surface was thoroughly washed to remove the residual antiseptics. The phage cocktails or placebo were applied on alternate days. The wounds were evaluated using the Bates-Jensen Wound Assessment Tool for the progress of wound healing. RESULTS: A total of 93.3% of the wound became sterile in 39 days (median sterility time), followed by complete healing by the end of 90 days in the phage group. Contrary to this, 83.3% of those on placebo therapy remained colonized by original bacteria or additional new bacteria without healing for up to 90 days. CONCLUSION: With the well-designed RCT, we could conclude that customized bacteriophage therapy using bacteriophage cocktails will definitely cure the chronic wound, irrespective of age, sex, diabetes status, and infection by MDR bacteria.

RESUMO

The recent approval of experimental phage therapies by the FDA and other regulatory bodies with expanded access in cases in the United States and other nations caught the attention of the media and the general public, generating enthusiasm for phage therapy. It started to alter the situation so that more medical professionals are willing to use phage therapies with conventional antibiotics. However, more study is required to fully comprehend phage therapy's potential advantages and restrictions, which is still a relatively new field in medicine. It shows promise, nevertheless, as a secure and prosperous substitute for antibiotics when treating bacterial illnesses in animals and humans. Because of their uniqueness, phage disinfection is excellent for ready-to-eat (RTE) foods like milk, vegetables, and meat products. The traditional farm-to-fork method can be used throughout the food chain to employ bacteriophages to prevent food infections at all production stages. Phage therapy improves clinical outcomes in animal models and lowers bacterial burdens in numerous preclinical investigations. The potential of phage resistance and the need to make sure that enough phages are delivered to the infection site are obstacles to employing phages in vivo. However, according to preclinical studies, phages appear to be a promising alternative to antibiotics for treating bacterial infections in vivo. Phage therapy used with compassion (a profound understanding of and empathy for another's suffering) has recently grown with many case reports of supposedly treated patients and clinical trials. This review summarizes the knowledge on the uses of phages in various fields, such as the food industry, preclinical research, and clinical settings. It also includes a list of FDA-approved bacteriophage-based products, commercial phage products, and a global list of companies that use phages for therapeutic purposes.

RESUMO

Gastric volvulus is an uncommon clinical condition with the potentially life-threatening complication of acute gastric necrosis. A wandering spleen may also be associated with gastric volvulus and can produce a diagnostic dilemma as the cause of an acute abdomen. We present a case of an elderly woman who presented with acute abdominal symptoms. She did not have the classical Borchardt triad to diagnose gastric volvulus and had a coexisting wandering spleen. Although torsion and ischemia of the wandering spleen were initially thought to be the cause of acute abdomen, a subsequent contrast-enhanced CT (CECT) scan confirmed a coexistent mesenteric-axial gastric volvulus with gangrenous changes. We present this case to highlight a rare combination of pathologies, either of which can confuse the diagnosis or cause a delay in management. Early diagnosis with CECT is emphasized, and segmental resection is feasible when the rest of the viscus can be preserved.

RESUMO

Primary cutaneous mucormycosis is a consequence of environmental Mucorales spores inoculation at the abraded skin. In a diabetic patient, these spores germinate quickly and disseminate hematogenously to the surroundings. Cutaneous mucormycosis is a rare but aggressive, invasive, and life-threatening fungal infection. Its presentation is nonspecific, but it rapidly results in necrosis of underneath tissues. Diagnosis can be readily made by KOH wet mount of excise tissue. However, a prompt diagnosis with multidisciplinary management is a prerequisite for a better outcome. We present a case of fatal cutaneous mucormycosis caused by Apophysomyces elegans, in a diabetic patient who succumbed to death despite extensive debridement and antifungal treatment.

RESUMO

Wound healing is a complex, highly regulated process that is important in sustaining the skin barrier function. The etiologic relation of specific metals is not adequately described for chronic non-healing wounds. The aim of this study was to estimate heavy and trace metals in chronic non-healing wound and their association with wound healing. The levels of zinc, selenium, copper, magnesium, chromium, cadmium, iron, and lead were estimated in serum of chronic non-healing wound patients using atomic absorption spectrophotometry. The tests were carried out in 50 patients with chronic non-healing wound and thirty healthy volunteers as control. The serum levels of elements namely zinc, selenium, copper, magnesium, and chromium were significantly reduced in chronic non-healing wounds (P < .001) as compared to control. Lead and cadmium levels had shown the significantly increasing trend in chronic non-healing wound cases (P < .001). The present study demonstrated a significant decrease in serum, levels of selenium, zinc, copper, magnesium, iron, and chromium levels in patients with chronic non-healing wound indicating an association between these elements and wound healing. To summarize the findings of our research, hence trace elements were decreasing in chronic non-healing wound patients suggesting their role in wound healing.

RESUMO

Background:Traumatic wound is a great challenging issue to surgeons, because of large in size, heavily contaminated, infected and unscenic. Infection proceeded to progressive tissue necrosis, septicemia, organ failure or even death. Majority has polymicrobial infections. Bacteriohage therapy will have revolutionized in the treatment of wound. The present study was planned to evaluate the efficacy of topical bacteriophage therapy on large traumatic wounds in comparison with conventional therapy. Methods:The Study conducted from Sept. 2018 to July 2020. Samples between 12- 60 years was taken into study. Customized bacteriophage applied over the wound after serial debridement in case and conventional dressing in control. Fifty four wounded person met the clinical inclusion criteria; 27 in each group. Wound swab and tissue biopsy was taken for bacterial isolation. Isolated specific phage was applied over the wound on alternate day till the wound become sterile and fit for further definitive management. Results: A significant and rapid improvement was observed in wound healing in cases then control group. Average number of day required for complete granulation of wound and attaining sterility was half in cases then control. The hospital stay of the patients on BT was half (20days) than those on CT (40 days). The financial analysis also favours the BT over CT as only 1/third expenditure incurred in BT group as compared to CT Conclusion:Topical Bacteriophage therapy is efficient, effective to clearing the infection in shorter length of time and cost effective for infected traumatic wounds as compared to conventional dressing.

RESUMO

BACKGROUND: A chronic wound usually results due to halt in the inflammatory phase of wound healing. Bacterial infections and biofilm formation are considered to be the basic cause of it. Chronic wounds significantly impair the quality of life. Antibiotics are now failing due to biofilm formation emergence of drug-resistant bacteria. OBJECTIVE: This study aims to see the effect of bacteriophage therapy in chronic nonhealing wound infected with the following bacteria: Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa. SUBJECT: Patients with chronic nonhealing wound not responding to conventional local debridement and antibiotic therapy were included in the study. The age of patients ranged between 12 and 60 years. METHOD: A total of 20 patients selected and tissue biopsies and wound swabs were taken for isolation of the bacteria. After confirmation of organism, a cocktail of customized bacteriophages was topically applied over the wound on alternate days till the wound surface became microbiologically sterile. Mean bacterial count and clinical assessment were done and compared at the time of presentation and after 3 and 5 doses of application. RESULTS: A significant improvement was observed in the wound healing, and there were no signs of infection clinically and microbiologically after 3 to 5 doses of topical bacteriophage therapy. Seven patients achieved complete healing on day21 during follow up while in others healthy margins and healthy granulation tissue were observed. CONCLUSION: Topical bacteriophage application may be quite effective therapy for the treatment of chronic nonhealing wounds.

RESUMO

PURPOSE: 5,10-Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme in folate metabolism and plays a major role in DNA methylation. There are two popular MTHFR polymorphisms known as C677T and A1298C which are found to be involved in folate metabolism and lowering the enzyme activity, thus may be linked with cancer development. This study aims to look at the association of these polymorphisms in gallbladder cancer. METHODS: Thirty patients each with gallbladder cancer, cholelithiasis, and normal gallbladder were genotyped for the above-given polymorphisms by PCR-restriction fragment length polymorphism (RFLP) method. RESULTS: C677T MTHFR polymorphism was not associated (χ(2) = 2.44, p = 0.85) with an increased likelihood of having gallbladder cancer. A1298C was significantly associated (χ(2) = 28.87, p < 0.001) with risk of developing gallbladder cancer. A1298C was significantly correlated with grade (r = 0.337, p < 0.001) and histopathology (r = 0.446, p < 0.001). CONCLUSION: This study proposed that MTHFR A1298C polymorphism may be associated with risk of developing gallbladder cancer, and there is no association between C677T polymorphism and gallbladder cancer.

RESUMO

Buruli ulcer (BU) is caused by Mycobacterium ulcerans and can manifest as a simple nodule or as aggressive skin ulcers leading to debilitating osteoarthritis or limb deformity. The disease is more prevalent in those living in remote rural areas, especially in children younger than 15 years. The exact mode of transmission is possibly through traumatic skin lesions contaminated by M ulcerans. IS2404 polymerase chain reaction from ulcer swabs or biopsies is a rapid method for confirmation of BU. In coendemic countries, HIV infection complicates the progression of BU, leading to rapidly spreading osteomyelitis. Treatment is principally medical, with antitubercular drugs, and surgery is utilized for complicated disease. Because of ineffective vaccination, primary prevention is the best option for control of the disease.
