Article Abstract
Background & Objective: Chronic suppurative otitis media is a fatal condition owing to its propensity for intracranial extension. The inadvertent use of antibiotics has led to resistance among causative organisms. The objectives of this study were to determine causative bacteria, their antibiotic resistance and susceptibility patterns, and their response to antibiotics after a one-month follow-up.
Method: It was a prospective study conducted in the ENT department of Khyber Teaching Hospital, Peshawar from June 2023 to March 2024. Ear swabs were collected for microscopy and bacterial culture. Statistical analysis was done using IBM-SPSS-20, and GraphPad Prism.
Results: Data was collected from 113 patients. The mean age of the patients was 22 + 2 years. Out of 113 samples, 97(85.5%) showed growth on culture whereas 16(14%) showed no growth, with 95 (98%) unimicrobial, while 2 (2%) showed polymicrobial growth. Pseudomonas aeruginosa was the commonest bacteria isolated 38(38%), followed by , , and . Gram-positive bacteria were susceptible to Linezolid (80%), followed by Vancomycin (76%), with resistance to Ciprofloxacin (75-84%), Ampicillin (70%), and Ceftriaxone (75-80%). Gram-negative bacteria showed susceptibility to carbapenem (50-100%) and Piperacillin/Tazobactam (50% to 93%), with resistance to Ciprofloxacin (50-87%), Ceftriaxone (87%), and Amoxicillin/Clavulanate (72-90%). After one month of follow-up, 82% of patients showed improvements, with noncompliance significantly associated with the persistence of symptoms (p<0.01).
Conclusion: Moderate to high resistance against ciprofloxacin, third-generation cephalosporin, ampicillin, amoxicillin plus clavulanate, and clindamycin is an eye-opener. Our results underscore the critical need for judicious administration of empirical antibiotics.

Miliary tuberculosis and central nervous system infection caused by hematogenous transmission from a primary subcutaneous tuberculous abscess: A case report.
Medicine (Baltimore)
September 2025
Department of Tuberculosis, Guiyang Public Health Clinical Center, Guiyang, Guizhou Province, China.
Rationale: We report an extremely rare case in which delayed diagnosis and treatment of Mycobacterium tuberculosis infection primarily involving the subcutaneous tissues of an extremity led to hematogenous dissemination of the infection and subsequent deterioration of the patient.
Patient Concerns: An 82-year-old man presented to our hospital with a painful mass on the right ankle for over a year, as well as persistent fever and shortness of breath for >14 days. He received piperacillin/tazobactam followed by meropenem, which failed to decrease his peak temperature.
Bronchiectasis evaluation 2025: pediatric and adult perspectives.

Division Pediatric Pulmonary Medicine, Department of Pediatrics, Vanderbilt University Medical Center, Nashville, Tennessee, USA.
Purpose Of Review: There is a significant overlap between the diagnostic evaluation for adult and pediatric patients with bronchiectasis; however, also important age-specific unique considerations. This review focuses on these specific considerations.
Recent Findings: Bronchiectasis refers to the radiographic evidence of dilation of distal and proximal bronchi secondary to chronic infection and inflammation.
Background: Hidradenitis suppurativa is a chronic inflammatory skin condition frequently associated with type 2 diabetes mellitus and obesity. Glucagon-like peptide-1 receptor agonists have emerged as promising agents for managing type 2 diabetes mellitus due to their potent effects on glycemic control and weight reduction. Recent evidence suggests that glucagon-like peptide-1 receptor agonists may also possess anti-inflammatory properties, potentially making them effective in treating inflammatory conditions, such as hidradenitis suppurativa.

Hidradenitis Suppurativa (HS) is a chronic autoinflammatory skin disease of the terminal hair follicle, whose pathogenesis is complex and multifactorial. Alongside a predisposing genetic background, environmental/epigenetic factors, alterations in the skin microbiome, and dysregulation of both innate and adaptive immune responses contribute to the persistent inflammatory network. Despite advancing knowledge, the exact molecular and cellular mechanisms underlying HS have yet to be untangled.

Medicine (Baltimore)
August 2025
Department of Gastrointestinal Surgery, The Second Affiliated Hospital of Nanchang University, Nanchang, China.
Rationale: The opportunistic pathogen Corynebacterium striatum has been generating more clinical infections in recent years, but secondary infections at different parts caused by it have been reported more rarely.
Patient Concerns: This case details a 52-year-old male patient who got an infection that advanced to multiple osteomyelitis and soft tissue abscess after block therapy for external humeral epicondylitis of the right arm. Unexpectedly, the chronic ulcerated region of the patient's neck was infested with Corynebacterium striatum due to inadequate treatment of the main infection, resulting in a secondary infection of the neck mass.
