The Increased Risk of Community-Acquired Methicillin-Resistant Staphylococcus Aureus in Neck Infections in Young Children

Evaluation of Antibiotic Sensitivity in Deep Neck Space Infections

Background Deep neck space infections (DNIs) are a major medical concern in the Indian community. Owing to the complex anatomy of the neck spaces and their communication with each other, accurate diagnosis becomes challenging. A thorough knowledge of the anatomy as well as the microbiological profile and antibiotic sensitivity is imperative to institute the appropriate surgical and medical management to the patient. Due to the advent of broad-spectrum antibiotics, the incidence of these infections have declined considerably over the last couple of decades. However, due to the extensive and unregulated use, the incidence of antibiotic resistance has also been increasing at an alarming pace.

Materials and Methods This cross-sectional observational study was conducted in the Department of Otorhinolaryngology at a tertiary care government hospital in an urban area. All patients who presented to the OPD or emergency over a period of 18 months and who fulfilled the eligibility criteria were included in the study. Pus was collected from the abscess, aseptically by needle aspiration using wide bore (18G) needle and transported under all aseptic measures within 24 hours for culture and sensitivity, KOH mount, and detection of AFB. Antibiotic sensitivity testing was done using the Kirby Bauer disc diffusion method and E-test.

Results Staphylococcus aureus as the most common infective organism followed by MRSA in the pediatric age group and Klebsiella pneumoniae in adults.

Conclusion Primary knowledge of individual antibiotic sensitivity is imperative to ensure prompt and adequate treatment of the patient with higher chances of complete resolution, concomitantly minimizing the risk of resistance. Inadequate and delayed treatment may lead to swift progression of the disease with significant morbidity and mortality.

Clinical Presentation and Microbiological Profile of Deep Neck Space Infections in Different Age Groups

Deep neck space infection (DNI), is defined as infections in the deep fascia enclosing potential spaces of the neck. In the past the diagnosis and treatment of DNI have challenged. The health care personnel at all levels. The complex anatomy and the deep location of this region remains a big problem with significant risks of morbidity and mortality. The aim of this study is to analyse the difference in clinical presentation and microbiology of DNI in different age groups. Eighty two patients with DNI which were managed at the Department of Otorhinolaryngology, ABVIMS and Dr. Ram Manohar Lohia Hospital New Delhi, between November 2017 and March 2019 formed the basis of our prospective cross sectional observational study. We observed that DNI is a frequent and potentially life threatening condition in children and adults despite the use of antibiotics. For appropriate surgical management knowledge of complex spaces of the neck and their communication with the other spaces is necessary.

The changing microbiology of neck abscesses in children: implications for antibiotic therapy

Objectives

To provide an update on the microbiology, sensitivity rates and antibiotic prescribing patterns for superficial neck lymph node abscesses at Scotland's largest paediatric tertiary centre. Findings were compared to historical data from our institution.

Methods

A retrospective case series was conducted of paediatric patients undergoing incision and drainage of a superficial neck lymph node abscess at the Royal Hospital for Children in Glasgow, from 2018 to 2021.

Results

Thirty-nine abscesses were identified. Methicillin-susceptible Staphylococcus aureus was the commonest micro-organism (28 per cent), followed by Streptococcus pyogenes (13 per cent). Eighty-two per cent of patients were administered a drug regimen containing co-amoxiclav. Only three children required a change in their antibiotics.

Conclusion

There was a significant change in causative micro-organisms, including a decrease in S aureus and an increase in the Streptococcus anginosus group. Empirical use of co-amoxiclav is recommended. In abscesses showing no clinical improvement, second-line options such as clindamycin, cefotaxime and vancomycin should be considered.

Geographic health disparities in the Los Angeles pediatric neck abscess population

OBJECTIVE

To assess geographical sociodemographic differences in neck abscesses that require surgical drainage in Los Angeles.

STUDY DESIGN

retrospective review.

METHODS

We reviewed the medical records of 119 consecutive pediatric patients at Children's Hospital Los Angeles (CHLA) from 2014 to 2017 with a diagnosis of a neck abscess requiring incision and drainage. Sociodemographic information including zip code of residence was extracted and analyzed with Chi-square, Fisher's exact test, and multivariate logistic regression.

RESULTS

The average age of patients with a neck abscess in this study was 3.4 years old, 53.8% were female, 54.6% were Hispanic, and 82.5% had public health insurance. 79% of patients had an abscess located in the superficial neck, and 10.1% had an abscess located in the retropharyngeal space. There were no significant differences in gender, race, type of health insurance, or income between patients that lived within 10 miles of CHLA versus those that lived farther than 10 miles. On multivariate analysis, zip codes with a high volume of neck abscesses were more likely to be lower income neighborhoods. Gender, race, type of health insurance, and distance from CHLA were not associated with zip codes with a high volume of neck abscesses.

CONCLUSION

Geographic areas in the greater Los Angeles community with a high volume of neck abscesses requiring incision and drainage at our institution were associated with lower income neighborhoods.
