RESUMO

INTRODUCTION: A 38-year-old African American woman presented with right hip pain and movement restriction. Her medical history included a right hip and knee arthroplasty 10 years prior, history of Slipped Capital Femoral Epiphysis and osteonecrosis of the hip. Preoperative assessment was significant for multiple comorbidities such as obesity (BMI > 38), hypertension, asthma. PATIENT CONCERNS: The patient presented with right hip pain, rated 7/10, and restricted hip flexion, adduction, and abduction. DIAGNOSIS: Recent imaging showed eccentric deterioration of the polyethylene lining of her prosthesis, acetabular hypertrophy on her right hip prosthesis, and chronic deformity of the pubic bone. INTERVENTIONS: Based on these findings, a revisional total hip arthroplasty was performed. After the surgical procedure, the WoundVAC and the percutaneous drain were applied outside the tensor fascia lata to reduce seroma and hematoma formation. Postoperative pain control, antibiotics and DVT prophylaxis were given. On post-op day 3, an irrigation and debridement with delayed primary wound closure was performed under sterile conditions. OUTCOMES: On postoperative assessment, the wound demonstrated adequate healing without any signs of infection. Sutures and staples were removed 4 weeks post-op. Upon palpation there was no edema, effusions, temperature changes, tenderness. Clinical inspection revealed symmetrical alignment of the pelvis and hips. Range of motion testing revealed restriction beyond 80 degrees upon flexion and beyond 5 degrees of adduction and 10 degrees of abduction. The surgical site was noted to be healed at 6 weeks post-op. The patient continued to do well to date, without exacerbations. CONCLUSION: Obesity increases the risk of post-operative complications and wound healing failure. Therefore, Vacuum-assisted wound closure (WoundVAC), a type of negative pressure wound therapy, was applied outside the tensor fascia lata post-operatively, where the surgical incision was made. Negative pressure wound therapy facilitates wound healing by stimulating angiogenesis and promoting granulation tissue formation, which in turn can reduce the risk of surgical site infection in obese patients undergoing total hip arthroplasty. Highlighted is the mechanism of fat migration in the promotion of wound healing after preoperative weight loss and exercise.

RESUMO

Patients with COVID-19 present with a myriad of comorbidities. An immunocompromised state like HIV in patients with COVID-19 can be life-threatening. We searched PubMed/Medline, Scopus, and Web of Science for case reports and case series about COVID-19 in HIV patients. We finally reviewed 20 case reports including cases of 43 patients with HIV and COVID-19. The mean age of 43 adult patients was 51.56 ± 27.56 years (range 24-76 years). Of these, 30 were male (69.77%), 11 were female (25.58%), and 2 were transgender (4.65%). A total of 25 patients (58.14%) were above 50 years of age. The most common cardiovascular comorbidities were hypertension and hyperlipidemia (48.8%), diabetes (20.93%), and morbid obesity (11.63%). Out of 43 HIV patients with COVID-19, 6 resulted in death (13.95%). All the patients who died were elderly above 50 years and required mechanical ventilation. HIV patients infected with COVID-19 had a high mortality rate. A high burden of pre-existing comorbidities and an advanced age in these patients make them prone to disease progression and worse outcomes.
