INTRODUCTION: Hydropneumothorax with a bronchopleural fistula is an infrequent but severe complication of necrotizing pneumonia associated with high morbidity and mortality. Few cases in the adult population have been reported. CASE REPORT: This is a case of a 76-year-old male patient who developed pneumonia caused by Pseudomonas aeruginosa and Klebsiella pneumoniae complicated by hydropneumothorax. He was managed conservatively with chest tube placement but denied surgical management and eventually died despite initial improvement...

INTRODUCTION: The incidence of invasive meningococcal disease is highest in infants and young children. CASE REPORT: Twin infants diagnosed two days apart with meningitis due to N. meningitidis serogroup B are presented. CONCLUSIONS: There has never been a report of concurrent meningococcal meningitis in twin brothers. We wanted to highlight the high likelihood of meningococcal transmission through household contacts and the importance of antibiotic prophylaxis and meningococcal vaccination recommendations for close contacts of these cases...

Peri-implantitis is a pathological condition in dental medicine that manifests as an inflammatory process affecting the tissues surrounding dental implants. Peri-implantitis occurs when the soft and hard tissues surrounding these implants become inflamed, leading to progressive destruction of the supporting bone. The etiology of peri-implantitis is multifactorial, involving microbial, host-related, and environmental factors. Microbial involvement in peri-implantitis can be explained either by direct in-situ virulence activation leading to pathogenicity, or by induction of low-grade chronic immune activation, leading to long-term persistence of a pro-inflammatory status...

Pseudomonas aeruginosa is one of the most common causes of diabetic foot infection globally. This study aimed to determine the global distribution of P. aeruginosa isolated from diabetic foot ulcer infection. PRISMA procedure was used to perform the current systematic review and meta-analysis. The Web of Science, MEDLINE/PubMed, Scopus, and other databases were searched for studies published in English from 2000 to 2022. Data was analyzed using the Comprehensive Meta-Analysis software (CMA). Keywords and MESH phrases included Pseudomonas aeruginosa , diabetic foot ulcer, P...

INTRODUCTION: This study aimed to examine the effect of commonly used non-antibiotic drugs (dexamethasone and tenoxicam), on treatment of Pseudomonas aeruginosa infections, antibiotic resistance and virulence in this pathogen. METHODS: Four antibiotics (gentamicin, cefepime, ciprofloxacin and meropenem) were investigated. The proteolysis and hemolysis were selected as virulence factors for investigation. In this work, we selected the following final concentrations: dexamethasone (0...

INTRODUCTION: Fosfomycin is an effective treatment for urinary tract infections (UTIs). It is not currently used in Sri Lanka to treat UTIs. Hence, this study was conducted to assess the fosfomycin susceptibility for E. coli in urinary isolates, with an aim to find the usability of fosfomycin in the context of high antibiotic resistance. METHODS: E. coli isolates were identified by the colony appearance and by performing biochemical tests for the urinary coliform isolates collected from two different hospitals in Western Province Sri Lanka, during the period of November 2021 to February 2022...

Dental pathologies of endodontic origin are varied in nature, and include infectious and non-infectious causes. Through this review, we aim to provide a deeper understanding of the role of bacterial involvement and in the pathogenesis of endodontic pathologies, by reviewing the relevant literature on the most common bacterial species involved, and their capacity to organize as biofilms. Furthermore, we focus on the most important recent updates in the management of endodontic infections, from a multidisciplinary perspective...

INTRODUCTION: Enterococcus casseliflavus is a rare pathogen in human infections, despite being widely distributed in natural environments. This systematic review aims to evaluate the evidence related to endophthalmitis caused by E. casseliflavus . METHODS: A thorough search of PubMed, PubMed Central, and Scopus databases was conducted, covering the period up to October 2022. RESULTS: A total of 53 records were identified, with 8 studies reporting a total of 21 cases meeting the inclusion criteria...

INTRODUCTION: Eggerthia catenaformis , a non-spore-forming anaerobic Gram-positive bacillus component of the human fecal microbiota has rarely been reported in human diseases. In almost every case described in current literature to date, dental diseases (abscesses, periodontitis, or caries), are the most common source of the infection which extends to the brain, cervical spaces, pulmonary parenchyma, the pleural cavity, the abdominal wall, and the abdominal cavity. CASE REPORT: An 82-year-old male Caucasian patient was admitted to our Emergency Department (ED) with a painless, right submandibular mass, dyspnea, and inspiratory stridor...

INTRODUCTION: Intravesical Bacillus Calmette-Guérin (BCG) instillation is the most effective adjuvant therapy for superficial urinary bladder carcinoma, prolonging disease-free survival. Although it is usually well tolerated, moderate to severe local or systemic infectious complications, including sepsis involving multiple organs, may occur. CASE REPORT: We report the unusual case of a man in his mid '70s who presented with septic shock and severe acute respiratory failure requiring intubation...

INTRODUCTION: Hafnia alvei is a Gram-negative, facultative anaerobic bacillus that is most often found as an enteric commensal. It is seldom considered to be pathogenic in immunocompetent individuals. CASE REPORT: We describe a case of a 23-year-old, previously healthy male, who presented to the emergency department with a two-day history of hemoptysis, mild dyspnea, pleuritic chest pain, fevers, and chills. Bloods revealed leukocytosis and elevated C-reactive protein...

INTRODUCTION: Febrile urinary tract infections (UTIs) in children are among the most serious bacterial infections. Inadequate treatment can lead to kidney scarring and permanent kidney damage. Eight to ten percent of children with UTIs could have concomitant bacteremia. The study aimed to estimate the prevalence of UTI-associated bacteremia and identify common organisms causing UTIs and their antimicrobial susceptibility patterns to help guide empiric antimicrobial therapy. METHODS: The current study was conducted over a 6-month period on children admitted with febrile UTIs at Alexandria University Children's Hospital...

INTRODUCTION: Thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy associated with severe ADAMTS13 deficiency that can be potentially fatal if not treated in a timely manner. CASE REPORT: A 49-year-old previously healthy woman was admitted with a 3-month history of thoracoabdominal pain and headache associated with loss of appetite, emesis, nocturnal diaphoresis, and unintentional loss of 10 kg. On admission she presented anemia, thrombocytopenia, schistocytes in peripheral blood smear, and ADAMTS13 in 1...

INTRODUCTION: Burkholderia pseudomallei is the bacterium that causes melioidosis. It is mostly a tropical disease, and particularly common in Southeast Asia and northern Australia. The intensive intravenous phase and the oral prolonged eradication phase are the two phases of melioidosis treatment. The current recommended treatment for melioidosis eradication is oral co-trimoxazole (TMP/SMX). CASE REPORT: Two patients were diagnosed with B. pseudomallei bacteremia without a focus and were treated with oral TMP/SMX with folic acid during the eradication phase...
