Uncommon first diagnosis of metastatic papillary thyroid carcinoma with “signet-ring” cells morphology through pericardial effusion

Published on: 20th January, 2022

OCLC Number/Unique Identifier: 9396216816

Malignant pericardial effusion is a usual and crucial exacerbation in malignancies. In some cases, pericardial effusion may be the first manifestation of the disease. Neoplastic pericarditis is extremely rare in thyroid cancer. Hereby, we describe the case of a 54-year-old man submitted to the hospital for chest pain and dyspnea. Clinical and radiological examinations were suggestive of pericardial effusion and mediastinal lymphadenopathy. The patient underwent pericardial drainage and surgical biopsy of a paratracheal lymph node. Pericardial biopsies were also taken. Histology study was compatible with metastatic papillary thyroid carcinoma with “signet-ring” cell morphology. Extended study of thyroid gland and function was performed and he was referred to oncologists for further treatment. Clinical presentation and histology are discussed emphasizing the rare correlation between pericardial pathology and metastatic thyroid carcinomas as the first diagnosis. Histopathologic findings of “signet-ring” cell morphology are very challenging for a differential diagnosis between thyroid carcinoma and other metastatic adenocarcinomas.

Post-operative agranulocytosis caused by intravenous cefazolin: A case report with a discussion of the pathogenesis

Published on: 18th February, 2022

A case of post-operative agranulocytosis which occurred in a 66-year-old woman following surgery for endometrial carcinoma is reported. The agranulocytosis had a rapid onset, being detected on the first post-operative day. The causative agent, cefazolin was given to the patient intraoperatively. The agranulocytosis persisted until the 22nd postoperative day. A bone marrow biopsy performed on post-operative day four showed a left-shifted myeloid maturation pattern but not a maturation arrest. The pathogenesis of drug-induced neutropenia/agranulocytosis is discussed. It is postulated that reversible binding of cefazolin to albumin accounts for the prolonged duration of agranulocytosis.

Spinal cord involvement in tuberculous meningitis: a case report and brief review of literature

Published on: 15th March, 2022

Introduction: Tuberculosis (TB) continues to pose a significant public health problem worldwide. Tuberculous meningitis (TBM) is the most devastating form of extrapulmonary TB however other forms of central nervous system (CNS) disease include tuberculoma and spinal arachnoiditis. TBM carries high mortality even for a patient who is already receiving treatment. The difficulty in diagnosis often leads to a delay in treatment and subsequent mortality. The emergence of Xpert ultra has improved the rapid detection of MTB and rifampicin resistance in CSF and is the preferred diagnostic tool in TBM.Case: In this case report we present a 33 years patient of concern who presented with progressive lower limb weakness associated with pain and paresthesia for 4 months, admitted via the Orthopedic unit with a diagnosis of spinal mass (meningioma, neurofibroma, or nerve sheath tumor) for which biopsy was done and revealed a chronic inflammatory process, necrotic bone lesions with no granulomas and no malignancy, he was later diagnosed with tuberculous meningitis and promptly started anti-tuberculous therapy with a dramatic recovery and improvement in neurological function.Conclusion: Tuberculous meningitis conditions have high morbidity and mortality yet diagnosis and start of treatment continue to experience an important delay. Clinicians should keep in mind the limitations of clinical presentation due to pleiotropy and current diagnostics and should employ a combination of diagnostic modalities in addition to a high index of suspicion to prevent morbidity in patients with TBM.

Primary central nervous system lymphoma post kidney transplantation: a case report

Published on: 3rd June, 2022

Introduction: Primary central nervous system (PCNS) posttransplant lymphoproliferative disease (PTLD) is a rare complication of solid organ transplantation and treatment is not yet standardized.Case presentation: Here we report the case of a 54-year-old man who underwent renaltransplantation 22 years ago for end-stage renal disease. He had been on long-term immunosuppressive treatment consisting of orally administered prednisolone 10 mg and then 5 mg daily and orally administered Mycophenolate Mofetil 500 mg twice daily. He presented in January 2019 to emergency with aphasia and then partial seizure. On brain MRI there was an expansive cortical mass in the left temporal lobe with perilesional edema. Biopsy revealed a diffuse large B-cell lymphoma. He was treated with one cycle of Cytarabine with his usual immunosuppressive treatment. In view of his renal allograft, he was not suitable for Methotrexate due to the risk of toxicity. He died on day 15 caused by a sepsis choc secondary to febrile neutropenia.Conclusion: PCNS-PTLD is regarded as one of the most serious posttransplant complications due to its high mortality. Further clinical and experimental investigations are required to develop optimal diagnostic and treatment modalities.

Published on: 5th July, 2022

OCLC Number/Unique Identifier: 9575034003

A 61 - year-old physically fit and athletic man presented to his dermatologist with a 10 mm raised, dark lesion on the left side of his neck. A complete skin examination did not show any other abnormal areas of skin. Pathology was found consistent with Merkel cell cancer, and the patient was referred to surgery for a wide local excision and sentinel lymph node biopsy. A PET scan did not show any other areas of concern. At surgery, one of two sentinel lymph nodes was found to be involved with Merkel cell cancer and the patient received postoperative radiation.

Pituitary gland metastasis from breast cancer: case report

Published on: 26th May, 2022

OCLC Number/Unique Identifier: 9524460826

Cancer metastasis to the pituitary gland is rare, but in most cases, it originates from a late-stage breast tumor or lung cancer. The most common symptoms of metastasis to the pituitary gland are diabetes insipidus and visual disturbance. The common site of metastasis is the posterior portion of the pituitary gland because it is highly vascularized. Metastases to this site represent 1% of all tumors [1]. Metastasis to the pituitary gland is difficult to diagnose by hormonal analysis and magnetic resonance imaging of the brain and requires biopsy for confirmation [2].

A case of coexistent acute severe alcoholic and Q fever hepatitis: The useful contribution of repeated liver biopsies

Published on: 23rd September, 2022

Acute Q fever is a worldwide zoonotic infection due to C. burnetii that may be associated with hepatitis. Nonspecific clinical and biological manifestations may accompany liver involvement, including hepatomegaly and elevated liver biological tests. However, the presence of jaundice is rare. Therefore, making a diagnosis of Q fever hepatitis may be difficult in an afebrile patient with jaundice of recent onset, altered liver function tests, excessive alcohol intake and no reported contact with animals. We report here the diagnostic work-up and complex clinical management of a patient presenting with acute hepatitis resulting from both C. burnetii infection and severe alcoholic steatohepatitis. Positive serology together with a detailed examination of the liver biopsy was able to reveal the coexistence of both Q fever hepatitis with typical fibrin-ring granulomas as well as florid lesions of alcoholic steatohepatitis. A combination of antibiotics, hydroxychloroquine and steroids, guided by the helpful description of changes in histological alterations on repeated liver biopsies during the course of the disease contributed to the slow but favorable outcome.

New insights of liquid biopsy in ovarian cancer

Published on: 29th September, 2022

Through the development of new analysis technologies, many issues regarding the approach to tumoral diseases have been elucidated. With analytical assays developed in the last years, various omics technologies have evolved in such a manner that the characteristics of tumor cells and products can be evaluated (assessed) in the bloodstream of cancer patients at different times. Ovarian Cancer (OC) is one of the most difficult to diagnose umors, with low survival rates due to the high heterogeneity of these diseases that are distinct in terms of etiology and molecular characteristics, but which simply share an anatomical appearance. Recent findings have indicated that several types of ovarian cancer classified into different histotypes are in fact derived from non-ovarian issues and share few molecular similarities. Within this context, ovarian cancer screening and diagnosis can be made through the evaluation of circulating tumor cells in peripheral blood using liquid biopsy technologies. Advances in the study of various molecules analyzed by liquid biopsy have shown that elucidation of intratumoural and intertumoural heterogeneity and spatial and temporal tumor evolution could be traced by serial blood tests rather than by histopathological analyses of tissue samples from a primary tumor. Therefore, evaluation of some molecules such as circulating tumor cells (CTC), circulating tumor DNA (ctDNA), circulating cell-free RNA (non-coding and mRNA, extracellular vesicles), tumor-educated platelets or different miRNAs using liquid biopsy could lead to improvement of patient management.

Risk factors for esophageal strictures in children and adolescents with eosinophilic esophagitis

Published on: 27th October, 2022

Studies in children with eosinophilic esophagitis (EoE) have reported esophageal strictures but none have examined risk factors associated with strictures. Aim: To assess risk factors associated with strictures in children with EoE. Methods: In this retrospective study, children with EoE seen over 20 years were separated into two groups; with and without strictures. Physical features, CBC, endoscopic findings, and biopsy of the distal and mid-esophagus were captured. Statistical significance with p - value and multivariate logistic regression was done. Results: Total patients 222 and 20 (9.1%) had strictures. Mean age of stricture patients 12.7 years (range 7-18) and non-stricture 9.3 years (range 1-17) (p = 0.006). Among stricture patients following were prevalent and significant; dysphagia (stricture 100% vs. non-stricture 41.6%, p = 0.0005) and food impaction (70.04% vs. 4%, p = 0.0005); EGD: rings and exudates were strongly associated with stricture, 45.0% vs. 4.5%, p = 0.0005 and 60% vs. 30.7%, p = 0.008, respectively. Abdominal pain was lower in the stricture group (5% vs. 31.2%, p = 0.017). Eosinophil counts were numerically more in the stricture group but not significant. Multivariate logistic regression confirmed that strictures are likely to occur among patients with dysphagia (p = 0.02, OR = 11.7, 95% LCL 2.0) and food impaction (p = 0.0001, OR = 80.9, 95% LCL 15.4), respectively, adjusted for age and gender. Conclusion: EoE children with dysphagia or food impaction have a higher chance of having an esophageal stricture. These EoE children 12 years or over with exudates or rings on endoscopy, should be treated and carefully monitored, to reduce the risk of stricture formation.

Complications of ultrasound-guided percutaneous native kidney biopsies in children: A single center experience

Published on: 5th January, 2023

Introduction: Percutaneous kidney biopsy is a necessary tool to diagnose many kidney diseases. However, major complications were reported in adults, including bleeding in the kidney or around it, creation of arteriovenous fistula, wound infection, damage to adjacent organs, or even loss of the kidney. Such complications can rapidly develop serious consequences. Exploring risk factors might help in preventing them.Objective: The current study aims to evaluate and explore the complications that happened after percutaneous kidney biopsy in children and associated risk factors.Methodology: A retrospective record-based study was conducted by reviewing the medical records of children with post-ultrasound-guided percutaneous kidney biopsy complications at King Saud Medical City, a tertiary hospital in Riyadh, Saudi Arabia during the period from May 2014 to June 2021. Data were extracted using pre-structured data collection sheet. Data collected included children’s age, gender, primary disease, laboratory findings, and kidney complications with needed management. Results: The study identified 76 children who had undergone 86 ultrasound-guided percutaneous kidney biopsies in the study period and fulfil the inclusion criteria. Children’s ages ranged from 1 years to 15 years with a mean age of 7.3 ± 4.0 years old. Most of the study children had nephrotic syndrome (61.6%; 53), followed by glomerulonephritis (25.6%; 22). Thirty-five (40.7%) children developed at least one of the complications. The most-reported complication was microscopic haematuria (32.6%; 28), followed by gross haematuria (3.5%; 3), Flank pain was reported among 3 (3.5%) children also and hematoma (1 child), only 2 children (3.9%) among those who had no complications recorded Haemoglobin drop > 2 g/dl compared to 3 of those who had complications with no statistical significance (p = .365). Prothrombin time was significantly higher among children who had renal complications than others who had not (11.7 ± 1.8 vs. 10.8 ± 1.2 seconds; p = .022).Conclusion: Suggestive by the low need to intervene in complications, ultrasound-guided percutaneous kidney biopsy is a relatively safe procedure in children. Even in the most commonly observed complication, i.e. hemorrhagic ones, blood transfusion is rarely needed.

Mammographic correlation with molecular subtypes of breast carcinoma

Published on: 14th February, 2023

Aim: To determine the correlation between mammographic features of breast cancer with molecular subtypes and to calculate the predictive value of these features. Materials and method: This is a retrospective study of breast cancer patients presenting between January 2017 and December 2021, who underwent mammography of the breast followed by true cut biopsy and immunohistochemical staining of the tissue sample. Breast carcinoma patients without preoperative mammograms, those unable to undergo histopathological and IHC examinations and h/o prior cancer treatment were excluded. On mammography, size, shape, margins, density, the presence or absence of suspicious calcifications and associated features were noted. Results: Irregular-shaped tumors with spiculated margins were likely to be luminal A/B subtypes of breast cancer. Tumors with a round or oval shape with circumscribed margins were highly suggestive of Triple negative breast cancer. Tumors with suspicious calcifications were likely to be HER2 enriched. Conclusion: Mammographic features such as irregular or round shape, circumscribed or noncircumscribed margins and suspicious calcifications are strongly correlated in predicting the molecular subtypes of breast cancer and thus may further expand the role of conventional breast imaging.

A challenging case of cutaneous sarcoidosis with unusual findings in a Syrian woman: a case report and review of literature

Published on: 14th March, 2023

Sarcoidosis is a granulomatous disease that involves multiple systems. Cutaneous involvement can manifest in patients with sarcoidosis and can present with or without systemic involvement. We present a case of cutaneous sarcoidosis in a Syrian woman that showed improvement after a combination of methotrexate and prednisolone therapy. The patient had unusual chest radiography findings and developed an unexplained fissured tongue after 5 days of receiving methotrexate therapy. In addition, the patient developed indurated erythematous plaque and papules on her upper right arm at the same location as a performed biopsy, which increased the diagnosis of a newly formed scar sarcoidosis although she was receiving her treatment.

A case of hepatic intraductal papillary neoplasm of the bile duct

Published on: 21st March, 2023

Introduction: Intraductal Papillary Neoplasm of the Bile ducts (IPNB) is a rare entity characterized by exophytic growth of the bile ducts.Case presentation: In this report, we present a 57-year-old male with no prior medical history consulted for upper right abdominal pain, jaundice and pruritus. Abdominal Ultrasound (US) and magnetic resonance imaging/Bili-magnetic resonance were performed. They revealed that the circumferential parietal thickening of the common hepatic duct had extended approximately 4 cm with moderate dilatation of the left intrahepatic bile ducts. Computed tomography showed no evidence of distant metastasis.Biopsy revealed a high-grade intraductal papillary neoplasm. After 40 days, the patient had left hepatectomy with resection of the main bile duct and the gallbladder. Macroscopic examination of the surgical specimen showed a dilatation duct at the hilum with thickening of their walls.The histopathology report revealed multiple intra-hepatic papillary neoplasms with high-grade dysplasia with an invasive carcinoma component in the left hepatic duct without extending to the biliary wall, classified as pT1N0.Conclusion: This premalignant lesion has the potential to transform into invasive carcinoma if not properly diagnosed.Our case illustrates how early identification can lead to potential surgical resection.

Diagnostic accuracy of apparent diffusion coefficient (ADC) in differentiating low- and high-grade gliomas, taking histopathology as the gold standard

Published on: 10th April, 2023

Gliomas are known to be one of the most grievous malignant central nervous system (CNS) tumors and have a high mortality rate with a low survival rate severe disability and increase risk of recurrence. Aim of his study is to determine the diagnostic accuracy of apparent diffusion coefficient (ADC) in differentiating low-grade and high-grade gliomas, taking histopathology as the gold standard. It is a Cross-sectional validation study conducted at the Armed Forces Institute of Radiology and Imaging, (AFIRI) Rawalpindi, Pakistan from 28th February 2022 to 27th August 2022.Materials and methods: A total of 215 patients with focal brain lesions of age 25-65 years of either gender were included. Patients with a cardiac pacemaker, breastfeeding females, de-myelinating lesions and malignant infiltrates, and renal failure were excluded. Then diffusion-weighted magnetic resonance imaging was performed on each patient by using a 1.5 Tesla MR system. The area of greatest diffusion restriction (lowest ADC) within the solid tumor component was identified while avoiding areas of peritumoral edema. Results of ADC were interpreted by a consultant radiologist (at least 5 years of post-fellowship experience) for high or low-grade glioma. After this, each patient has undergone a biopsy in the concerned ward, and histopathology results were compared with ADC findings. Results: Overall sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of apparent diffusion coefficient (ADC) in differentiating low- and high-grade gliomas, taking histopathology as the gold standard was 93.65%, 87.64%, 91.47%, 90.70% and 91.16% respectively. Conclusion: This study concluded that apparent diffusion coefficient (ADC) is the non-invasive modality of choice with high diagnostic accuracy in differentiating low- and high-grade gliomas.

Evaluation of a Weight-Based Mycophenolate Mofetil Dosing Protocol for Kidney Transplant Maintenance Immunosuppression

Published on: 28th July, 2023

To evaluate the safety and efficacy of weight-based mycophenolate mofetil (MMF) dosing in adult kidney transplant recipients (KTR), this single-center retrospective study of adult KTR compared biopsy-proven acute rejection (BPAR), infections, hospitalizations, granulocyte colony-stimulating factor (G-CSF) use, and MMF dose changes within one year of transplant pre-and post-implementation of a weight-based MMF dosing protocol. Adult patients who received a kidney transplant at University Health Transplant Institute were reviewed for inclusion. Patients in the weight-based MMF group received 1000 mg twice daily by the first clinic visit if ≥ 80 kg, 750 mg twice daily if 50-79 kg, and 500 mg twice daily if < 50 kg. Patients in the fixed-dose MMF group received MMF 1000 mg twice daily. A total of 170 KTR (50.0% ≥ 80 kg, 44.1% 50-79 kg, 5.9% < 50 kg) were included. Baseline characteristics were similar between groups. The majority of patients were middle-aged Hispanic males and received lymphocyte-depleting induction therapy. Incidences of BPAR, infection, and hospitalization were similar between both groups at one-year post-transplant. Weight-based MMF dosing is safe and effective in adult KTR.

Cardiac Tamponade as the Cause of Pulmonary Edema: Case Report

Published on: 17th August, 2023

Introduction: Cardiac tamponade is an emergency syndrome that requires fast diagnosis and treatment; otherwise patient follows obstructive shock and cardiac arrest. Case report: A 70-year-old female was brought to the emergency department with hypoxemia. She had a history of progressive dyspnea over the past three weeks. Past medical history includes smoking. On physical examination: tachypnea, hypoxemia (SaO2 89%), jugular venous distention, arterial pressure 220/100 mmHg, heart rate rhythmic of 82 bpm. On pulmonary auscultation: diffuse and bilateral crackles. Lung ultrasound showed a bilateral B line and the echocardiogram demonstrated a pericardial effusion with signs of tamponade. A pericardiocentesis evacuated 620 ml of hemorrhagic fluid and the patient was transferred to the intensive care unit, hemodynamically stable, with SaO2 95%. At the ICU the echocardiogram, showed resolution of the cardiac tamponade and a tumor adhered to the lateral wall of the left ventricle. Chest CT demonstrated: a left lung tumor, infiltrating the pericardial sac. A pericardium biopsy demonstrated undifferentiated carcinoma. Discussion: Cardiac tamponade diagnosis requires a high level of suspicion. Respiratory failure, chest pain, and shock, observed in cardiac tamponade, are also present in different diseases. The most common finding of cardiac tamponade is dyspnea (78% of cases). Our patient had dyspnea due to pulmonary edema, secondary to left ventricle diastolic dysfunction caused by the tamponade. A bedside echocardiogram made the diagnosis of cardiac tamponade and guided the effective pericardiocentesis. Conclusion: Cardiac tamponade must be suspected in all cases of acute dyspnea. Echocardiogram is the method of choice for the diagnosis and for guiding the pericardiocentesis.

Pneumopericardium: A Rare Complication of Antireflux Surgery

Published on: 23rd August, 2023

Pneumopericardium is a rare clinical entity, occurring in the setting of thoracic trauma, malignancies, or mechanical ventilation. Very few cases report pneumopericardium as a complication of gastrointestinal tract surgery. Signs and symptoms may be frustrating, ranging from asymptomatic to chest pain, sepsis, hemodynamic instability, pericarditis, or even cardiac tamponade. Clinical pathognomonic signs of pneumopericardium include pericardial metallic tinkling friction rub and mill wheel murmur. Diagnostic work-up includes electrocardiogram, chest radiography, and, computed tomography imaging. A gastro pericardial fistula should be considered a rare differential diagnosis for acute chest pain in patients with a history of gastroesophageal surgery. Rapid recognition and treatment avoid life-threatening complications. The successful outcome of gastro pericardial fistula treatment depends on both emergency and definitive surgical management. The survival rate with conservative management is poor.We present the case of a 78-year-old patient suffering from pneumopericardium and pericardial infusion, due to a fibrotic fistula between the Nissen’s valve, occurring 10 years after redo antireflux surgery. Treatment included broad-spectrum antibiotics, and emergency surgery for pericardial drainage, biopsy of the valve’s defect, suture, and omentoplasty.

Gene Expression and Functional Analysis in Patients with Acute and Chronic Renal Allograft Rejection

Published on: 3rd November, 2023

Kidney transplantation is the therapy of choice for patients with end-stage kidney disease (ESKD). Nevertheless, the main limitation for long-term graft survival is immune-mediated rejection. Some authors have proposed that differences in immune effector mechanisms are influenced by underlying molecular mechanisms; thereby, the identification of differentially expressed genes in acute or chronic rejection in non-invasive samples such as urine may be essential for the identification of potential biomarkers and biological processes associated with allograft outcomes. Our aim was to explore differences in gene expression and functional categories associated with acute and chronic kidney rejection in blood, biopsy, and urine of kidney transplant patients using RNA-Seq. RNA was isolated and sequenced implementing standard protocols. Analyses were addressed to identify differentially expressed genes (DEGs) and Functional Categories of Gene Ontology comparing between samples. Then we focused on immune genes and pathways to identify their association with the allograft. We identified a significant transcriptional similarity between biopsy and urine, in comparison with blood in acute and chronic rejection. Functional analyses suggested an enrichment of immune processes such as antigen processing and presentation, and regulation of B cell receptor signaling pathway in blood of acute and chronic rejection, respectively. Additionally, we observed an increase in expression of chemokines in biopsy and urine of both outcomes along with an increase in chemokine receptors in blood. Our findings suggest that urine is suitable for identifying potential biomarkers and biological processes related to renal allograft rejection, as it shares a significant number of regulated genes with biopsy.

Rare Case of Dense Deposition Disease with Combined C3 and C4d Deposits with MYH9-related Mutation

Published on: 14th November, 2023

Background: The C3 glomerulopathies are a group of rare forms of glomerulonephritis with an incidence of 1-2 cases per million. It is mainly characterized by dysregulation of the alternative complement pathway. It is further classified morphologically based on electron microscopy ultrastructural findings into Dense Deposition Disease (DDD) and C3 glomerulonephritis. DDD is normally characterised by C3 Deposits. Case: We report a rare case of a young Emirati male who presented with sub nephrotic proteinuria and microscopic haematuria on routine evaluation. Renal biopsy showed features of DDD with combined C3 and C4 deposits. The retinal evaluation showed features of Drusen classically seen in DDD. Genomic study showed heterozygous mutation in c.5842G>C (p.Asp1948His) variant of uncertain significance in MYH9 gene. Discussion: C3 Glomerulopathy is a type of immune mediated disease previously classified as membranoproliferative glomerulonephritis. DDD is mainly characterised by C3 deposits in the glomerular basement Membrane. Our case has both C3 and C4d deposits, which is a rare entity. It shows the activation of both classical and alternate pathways. Conclusion: Dense deposition disease is a rare complement mediated glomerulopathy. It is characterised by C3 deposits. Dense deposition disease with combined C3 and C4d deposits is a new entity. The treatment and prognosis of such cases will be different and unique compared to the normal cases of DDD.

Comparative Evaluation of the Effectiveness of Methods for the Treatment of Surgical Soft Tissue Infection

Published on: 17th November, 2023

Background: The presence of a multifaceted microbiological etiological factor of surgical infection and differentiated sensitivity to antibacterial drugs determines the need to develop more effective means and methods of influencing the purulent microflora of wounds. Physical treatment factors, in particular, low-frequency ultrasound and ionised plasma flows, should be considered promising for solving this problem.Materials and methods: The research was carried out based on the Scientific Center of Microbiology and the clinic of the Tashkent Medical Academy. Bacteriological studies of wound discharge and biopsy material were carried out. We studied the material of purulent-inflammatory diseases of soft tissues.Results: Wound-sounding through a dioxidine solution is most effective against gram-negative bacteria, and ultrasonic cavitation in combination with iodopyrone is most effective against gram-positive microorganisms. Treatment of purulent wounds with low-frequency ultrasound through a mixture of iodopyrone solution and ascorbic acid is effective against gram-positive and gram-negative microbes. Argon plasma flows have a high bactericidal effect mainly on gram-negative bacteria.Conclusion: The obtained data substantiate the need to choose a physical method of treatment of purulent wounds depending on the species composition of the wound microflora.
