Acute septic arthritis: remember gonorrhea

A Mysterious Case of Left Shoulder Pain in AIDS: A Case Report and Literature Review

Neisseria (N.) gonorrhea is a gram-negative diplococcus and one of the most commonly reported sexually transmitted infections (STIs) in the United States. Disseminated gonococcal infection is a rare but serious complication of N. gonorrhoeae infection that can result in arthritis-dermatitis syndrome or purulent gonococcal arthritis. Co-infection with human immunodeficiency virus (HIV) has been shown to reduce the efficacy of complement recruitment, which may lead to an increased risk of disseminated gonococcal spread. We present a case of a 41-year-old male with concomitant HIV-gonorrhea infection complicated by rare chronic subacute septic arthritis localized to the left shoulder. The patient had a history of HIV, hypertension, and diabetes, and presented with symptoms, including diarrhea, oral thrush, body aches, and fevers. During his hospitalization, the patient developed increasing left shoulder pain, and imaging and joint aspiration revealed N. gonorrhoeae as the causative agent. The patient was treated with appropriate antibiotics and showed improvement. This case highlights the importance of considering disseminated gonococcal infection as a potential complication of N. gonorrhoeae infection, particularly in patients with concomitant HIV infection, and the need for prompt diagnosis and appropriate treatment to prevent complications.

Right hip gonococcal septic arthritis treatment with successful transition to oral fluoroquinolone

We present a case of gonococcal septic arthritis of the right hip diagnosed via synovial fluid cultures. Antimicrobial susceptibility testing of the synovial fluid demonstrated susceptibility to tetracycline, ciprofloxacin, cefixime and ceftriaxone. Our patient was initially treated with ceftriaxone and was successfully de-escalated to oral levofloxacin to complete the treatment. This case is interesting given the rarity of disseminated gonococcal infections in the 21st century and that most clinical isolates of Neisseria gonorrhoeae are increasingly resistant to fluoroquinolones.

Pyogenic Arthritis

The incidence of septic arthritis among children in developed countries is estimated to be 4 to 10 cases per 100,000 children per year, peaking at about age 3 years. The most common causative organism is Staphylococcus aureus, although the microbiology varies by age. Prompt diagnosis and treatment is critical to prevent long-term sequelae. Empiric therapy should target the most likely causative organism(s) and total duration generally falls between 10 days and 4 weeks depending on clinical course, patient age, and organism. A short intravenous course is sufficient in most cases. Unusual and alternate causes of arthritis should be considered in special cases. [Pediatr Ann. 2019;48(9):e354-e359.].

Septic Arthritis of the Wrist

Septic arthritis of the wrist is an uncommon condition, but one that can result in substantial morbidity. Timely identification and treatment is critical to patient care. No serum laboratory values have been shown to consistently confirm wrist joint infection. Thus, diagnosis is made based mainly on a thorough patient history, physical examination, and joint aspiration. When infection is suspected, aspiration of the wrist should be performed to confirm the diagnosis. Broad-spectrum antibiotics and joint aspiration or surgery are required to manage the infection and prevent sequelae.

The Hip Restoration Algorithm

BACKGROUND

Despite the rapid advancement of imaging and arthroscopic techniques about the hip joint, missed diagnoses are still common. As a deep joint and compared to the shoulder and knee joints, localization of hip symptoms is difficult. Hip pathology is not easily isolated and is often related to intra and extra-articular abnormalities. In light of these diagnostic challenges, we recommend an algorithmic approach to effectively diagnoses and treat hip pain.

METHODS

In this review, hip pain is evaluated from diagnosis to treatment in a clear decision model. First we discuss emergency hip situations followed by the differentiation of intra and extra-articular causes of the hip pain. We differentiate the intra-articular hip as arthritic and non-arthritic and extra-articular pain as surrounding or remote tissue generated. Further, extra-articular hip pain is evaluated according to pain location. Finally we summarize the surgical treatment approach with an algorithmic diagram.

CONCLUSION

Diagnosis of hip pathology is difficult because the etiologies of pain may be various. An algorithmic approach to hip restoration from diagnosis to rehabilitation is crucial to successfully identify and manage hip pathologies. Level of evidence: V.

Gonococcal tenosynovitis in two HIV-infected heterosexual men: delayed diagnoses following negative urine nucleic acid amplification testing

With recent increases in annual gonorrhoea incidence and disproportionately high infection rates amongst men who have sex with men, the clinical picture of disseminated gonococcal infection is changing. We present two cases where consideration of, and investigation for, disseminated Neisseria gonorrhoeae infection provided the answer when routine inpatient diagnostics had been unsuccessful.

Emergency department management of sexually transmitted infections

Patients seeking treatment for sexually transmitted infections (STIs) account for a large number of emergency department (ED) visits per year. Despite the large volume of patients, STIs are often missed or treated inappropriately. Due to the high prevalence and incidence of STIs in the United States, it is important that emergency practitioners recognize symptoms consistent with STIs, and treat presumptively. This practice leads to overtreatment of STIs; however, when weighed against the public health risk and complications of untreated disease, empiric treatment is recommended. This article provides an overview of STIs encountered in the ED and recommendations for their treatment.
