Rhino-orbital Mucormycosis in a COVID-19 Patient: The First Case in Malaysia

Mucormycosis is an aggressive and potentially fatal fungal infection caused by fungi of the order Mucorales. There has been an increase in the number of cases of rhino-orbital mucormycosis in people with COVID-19, particularly in India. Rhino-orbital-cerebral mucormycosis is the most common manifestation of mucormycosis associated with COVID-19. We report the first case of rhino-orbital mucormycosis in a diabetic patient with SARS-CoV-2 infection in Malaysia. The diagnosis of mucormycosis was confirmed by histopathological examination, but the fungal culture and PCR results were negative. He was treated with antifungal therapy and had extensive debridement. Treatment of mucormycosis requires a multidisciplinary approach that includes addressing underlying risk factors, effective antifungal therapy, and surgical debridement.

Cases of Lower Extremity and Perianal Burns at the Burn Center in the Southeast Anatolia of Turkey

Introduction: In this study, the aim is to discuss the cases of lower extremity and perianal burns at the burn center in the southeast Anatolia of Turkey. Material and methods: A 4-year retrospective study was conducted on 775 patients who had been admitted to Gazi Yaşargil Training and Research Hospital Burn Centre with lower extremity and perianal burn injuries between January 2016 and January 2020. Results: Of the patients, 427 were male and 348 were female. Scald burns are most commonly affect the perianal and lower extremities. The right lower extremity was affected in 602 (77.7%) patients, the left lower extremity was affected in 574 (74.1%) patients and the perineum was affected in 70 (9.0%) patients. Most burn injuries occur in individuals between 0 to 4 years old, and the rate of burn injuries gradually decreases in individuals outside of this age range. No patient underwent colostomy for perianal burns. Conclusion: Early, aggressive and extensive debridement, in addition to adequate antimicrobial therapy, should be performed as the basis of treatment.

Propionibacterium acnes causing non-contiguous, multifocal spondylodiscitis in an immunosuppressed patient

This report describes a case of a spondylodiscitis in an immunocompromised patient with an HIV infection caused by Propionibacterium acnes. The patient was admitted to hospital with a sudden loss of motor function and sensation in both of the patient’s legs. A biopsy taken during the first debridement operation proved to be negative for Mycobacterium tuberculosis DNA and growth, but was positive for the growth of P. acnes. Following a course of antibiotic therapy and the aforementioned debridement, the patient was moved to a specialised clinic for physical therapy. The patient’s condition quickly deteriorated, and the patient once again required extensive debridement. Repeated spinal surgery, antibiotics for 12 weeks and subsequent rehabilitation resulted in almost complete recovery of sensorimotor limb function.

Fungal central skull-base osteomyelitis: atypical presentation and management issues

Mucormycosis is a very commonly encountered disease in the sinonasal region in patients with diabetes and immunocompromised status specially in the northern part of the Indian continent. Due to its fulminant nature and involvement in the rhino-orbital-cerebral region, prognosis is poor even after extensive debridement and amphotericin-B therapy. We present a case with diagnosis of sarcoidosis being treated with systemic steroids who developed sudden-onset ptosis and left lateral rectus palsy. On radiological evaluation with MRI, a heterogenously peripherally enhancing lesion was seen in the nasopharynx suggestive of nasopharyngeal abscess. The patient was taken up for emergency surgery; a necrotic lesion with destruction of sphenoid bone, pterygoids and clivus was seen originating in the nasopharynx. The lesion on fungal staining came out to be broad aseptate hyphae suggestive of mucormycosis.

<i>Candida</i> fracture-related infection: a systematic review

Background: The aim of this study is to summarize and improve knowledge regarding a Candida fracture-related infection (CFRI) through a systematic review on the topic, accompanied by a case report. Methods: A systematic review and meta-analysis based on PRISMA statement were conducted on the CFRI topic. The following combined search terms were used to explore PubMed, Cochrane, and the Embase database: “fungal infection”, “candida”, “fracture related infection”, “bone infection”, “orthopedic infection”, “internal fixation”, “post-traumatic infection”, and “osteomyelitis”. Results: Out of 1514 records, only 5 case reports matched the selection criteria and were included. Moreover, a new case of CFRI, not previously described, was reported in this paper and reviewed. The main risk factors for CFRI were open wounds (three cases) and immunodeficiency (three cases). Initial improvement of clinical and laboratory signs of infection was noted in all cases. In the available short-term follow-up (mean 12.1 months; range 3–42), the reoperation rate was 33.3 %. Using a strategy based on extensive debridement/resection methods and prolonged systemic antifungal therapy (mean 8.8 weeks; range 6–18), four of six cases (66.6 %) were cured. Bone union occurred in three out of six cases. Conclusion: There is very low-quality evidence available regarding CFRI. Candida infections in surgically treated fractures are rare but difficult-to-treat events, with a slow onset, unspecific symptoms or signs, and a significant relapse risk; therefore, they still represent a current diagnostic challenge. The existing fracture-related infection treatment algorithm combined with long-term systemic antifungal therapy has an anecdotal value and needs more extensive studies to be validated.

Fatal Case of a Contained Ruptured of the Infrarenal Aorta due to Simultaneous Primary Aortocaval Fistula and Aortoenteric Fistula

We report an extremely rare case of primary aortocaval fistula with simultaneous development of an aortoenteric fistula in a 68-year-old man. The patient developed under oral anticoagulation a spontaneous intracaval aortic rupture. An emergency intervention was performed with a covering of the fistula with an aorto-uniiliac stent graft and a femoro-femoral crossover bypass. One week later, the patient was transferred to our institution with the diagnosis of a psoas abscess and a suspected concomitant aortoenteric fistula. We performed a complete explantation of the endograft and implanted it after extensive debridement an aortobiiliac bypass, made of bovine pericardium. The postoperative course was complicated, first by bleeding from the left iliac anastomosis, and then by bleeding from the proximal aortic anastomosis. The entire graft was explanted and an axillo-femoral bypass was implanted. The patient then developed a multi-organ failure and died 3 months later. If possible, an extended surgical debridement and resection of all infected tissue with in situ reconstruction is the gold standard. However, with this therapy, there is still a high risk of reinfection. Long-term antibiotic management is mandatory.

Treating surgical site infection following posterior instrumentation with free-style deepithelialized propeller flap: A case report

Surgical site infection is a challenging situation for all types of surgeons. Extensive debridement with or without implant removal can create soft tissue defects. A well-vascularized, adequate soft tissue is needed to cover the wound and to fill the dead space for proper healing. Herein, we describe our approach to a large posterior trunk defect with dead space and our solution to manage an intraoperative complication using a free-style deepithelialized propeller flap.

Surgical management of extensive aortic root endocarditis with ventricular septal rupture: A case report

A 79-year-old man was referred for severe cardiac decompensation. Chest radiography showed severe pulmonary edema, and transesophageal echocardiography revealed a large quantity of vegetation on all aortic valve leaflets with severe aortic valve regurgitation, heterogeneous cavities adjacent to the aortic annulus, and ventricular septal rupture. We performed thorough and extensive debridement of the aortic root; including the infected ventricular septum, reconstructed the ventricular septum and aortic root using autologous and bovine pericardial patches; and placed a bioprosthetic stented valve. The patient was discharged without any complications, and without recurrence of the endocarditis in the four years post-surgery.

Neuropathic foot ulcer

Objective: To determine the microbiological profile and antimicrobial susceptibility patterns of organisms isolated from chronic osteomyelitis secondary to neuropathic foot ulcers; secondarily, to describe the clinical outcomes of 52 patients admitted to a neuropathic foot referral center. Methods: Retrospectively chart review of 52 patients with clinically infected neuropathic foot ulcers admitted to our service for treatment between 2005 and 2013. Tissue samples were collected for culture at the operating room after extensive debridement in order to determine the infectious agents and their resistance profile using the disk-diffusion technique, following CLSI criteria. Results: A total of 52 patients were analyzed (40 males and 12 females). The mean age was 58 (37-72) years. Each patient presented with an average of 2.13 microorganisms, distributed as follows: 51% Gram-positive cocci, 43% Gram-negative bacilli. Among Staphylococcus aureus isolates, the prevalence of methicillin resistance was almost 50%, and the prevalence of coagulase-negative staphylococci (CoNS) was more than 75%. Conclusion: S. aureus, E. faecalis, and CoNS were the most frequently isolated pathogens. Methicillin resistance was highly prevalent. A combination of extensive surgical debridement and prolonged antimicrobial therapy led to remission of infection in 77% of patients. Level of Evidence IV; Therapeutic Studies; Case Series.
