A Case of Pustular Pyoderma Gangrenosum Misdiagnosed as Acute Febrile Neutrophilic Dermatosis in a Pediatric Patient

Background

Pyoderma gangrenosum (PG) is a rare cause of skin ulcers in children, posing challenges in diagnosis and treatment. As the disease is often associated with conditions such as inflammatory bowel disease (IBD), rheumatoid arthritis, haematological disorders and other diseases, diagnosis and treatment often require cooperation with other medical departments. Accordingly, dissemination of information about the disease to doctors in departments other than dermatologists, especially paediatricians, can help in its early detection.

Case Presentation

The 11-year-old pediatric patient in the case initially diagnosed with acute febrile neutrophilic dermatosis was eventually confirmed as pustular PG through histopathological examinations of skin and other relevant examinations. The medical condition is lessened after treatment with a combination of glucocorticoids and adalimumab.

Conclusion

PG is relatively rare in clinical settings, particularly among pediatric patients exhibiting persistent high fever and signs of pustular pyoderma gangrenosum. This case underscores the importance of considering the potential diagnosis of pediatric pustular PG when confronted with a child presenting persistent high fever and pustules after trauma. Additionally, the proactive initiation of adalimumab emerges as a promising treatment option for pediatric IBD -associated pustular PG.

A Case of Anaplastic Large Cell Lymphoma Misdiagnosed with Keloid

We report a case of a patient initially diagnosed with keloid and eventually diagnosed by skin histopathology and immunohistochemistry with primary cutaneous ALK-negative anaplastic large cell lymphoma.

Knee Pain After Retrograde Intramedullary Nailing with Surgical Implant Generation Network of Femur Shaft Fractures at Public Hospitals in Bahir Dar City, Ethiopia: Analysis of 6-Months Follow-Up Results

Background

The incidence of femur fractures in young and elderly people has increased, particularly in countries with limited resources like Ethiopia. Intra-medullary nailing (IM) has been an effective and cost-effective method of treating long bone shaft fractures, but it can lead to complications such as knee pain.

Purpose

This study aimed to evaluate knee pain and its associated factors following retrograde intramedullary nailing for femur fractures.

Patients and Methods

The study followed 110 patients diagnosed with femur fractures and treated with retrograde SIGN Standard Nail or Fin Nail from January 2020 to December 2022 at two hospitals in Ethiopia. The patients were followed up for at least 6 months, and data were collected from medical charts, patient interviews, and phone calls to patients who did not attend the follow-up appointment. Binary logistic regression analysis was used to identify factors associated with knee pain.

Results

The study showed that 40 patients reported knee pain at 6-months follow-up, making a prevalence of 36.4%. Factors significantly associated with knee pain were a time of injury to nailing (AOR=4.23, 95% CI: 1.28-13.92), use of a screw to the medial cortex (AOR=9.30, 95% CI: 2.90-12.74), and fracture site (AOR= 2.67, 95% CI: 14.01-7.03). Specifically, the longer the time from injury to nailing, the higher the risk of knee pain. The use of a longer screw to the medial cortex and a fracture site were also positively associated with knee pain.

Conclusion

This study concludes that although retrograde intramedullary nail fixation is an effective method for femur fractures, it often results in knee pain. Approximately 4 of 10 patients suffered from knee pain in this study. Avoiding delayed surgical management and minimizing the use of prominent metalwork may reduce knee pain.
