ABSTRACT
Osteomyelitis of the jaw is an uncommon infection that arises from the flora of the oral cavity or sinuses and affects immunocompromised and polymorbid patients. Treatment includes surgical debridement and long regiments of broad-spectrum antibiotics. We present three cases of complicated jaw osteomyelitis presented with concurrent COVID-19 infection, including only two reported cases of odontogenic COVID-related osteomyelitis. The two mandibular cases were patients in their 30s with no comorbidities. The first case was an asymptomatic COVID-19-positive patient who developed an odontogenic infection after tooth extraction that was complicated by the second bout of abscess formation and localized osteomyelitis. The second case was a COVID-19-positive patient with an odontogenic infection that presented as airway compromise due to trismus and neck edema, which required an emergency tracheotomy. He developed osteomyelitis of the mandibular ramus that was reconstructed with a titanium plate. The third case was a polymorbid post-COVID-19 patient who developed a protracted infection of the maxillary sinus that resulted in the loss of an eye, destruction of the maxilla, palate, and parts of nasal cavum, and oronasal incontinence. The defect was reconstructed with a microvascular anterolateral thigh flap. We hypothesize that COVID-19-related immune dysfunction and microvascular changes contributed to osteomyelitis in our patients.
ABSTRACT
Lemierre's syndrome refers to the septic thrombophlebitis of the internal jugular vein. The condition typically begins with an oropharyngeal infection and frequently involves inflammation within the wall of the vein, infected thrombus within the lumen, surrounding soft tissue inflammation, persistent bacteremia, and septic emboli. Lemierre's syndrome is a rare disease; it occurs most commonly in otherwise healthy young adults. The most common etiologic agent is Fusobacterium necrophorum. We present a case of Lemierre's syndrome in a young girl and the role of extracorporeal method of blood purification with continuous venous hemodiafiltration with the use of a highly adsorptive membrane (AN69 HeprAN), thus achieving the combined elimination of cytokines and endotoxins. The use of advanced methods, along with an antibiotic and surgical treatment, will certainly help reduce mortality in this syndrome.
ABSTRACT
Aim A SARS Coronavirus 2 (COVID-19) pandemic drastically changed the way the health system works. In Croatia, lockdown measures to curb virus spread lasted from March to May 2020, and all non-essential medical procedures and patients' visits have been cancelled. The study aimed to compare patients' flow and interventions in the surgical department before, during and after the lockdown period. Methods This cross-sectional study analysed the workload at the Maxillofacial and Oral Surgery Department (Department), Osijek University Hospital, during the COVID-19 pandemic (March-May 2020) and four subsequent months. The same period of 2019 was compared as a control. The data were subtracted from hospitals' electronic database. Results During COVID-19 lockdown from March to May 2020 the number of hospitalizations (306 vs. 138), surgical procedures (306 vs. 157), and scheduled outpatient visits (2009 vs. 804), dropped significantly as compared to 2019. The number of skin tumour removals was halved (from 155 in 2019 to 58 in 2019) (p<0.001), and the number of emergency patients was unchanged in the 3-month period. A significant decrease in outpatient visits and hospital admissions continued after the lockdown (p<0.001). Conclusion A decrease in the number of outpatient visits, hospitalizations, and tumour removals may result in larger proportions of patients with advanced cancers in the future. The second wave of COVID-19 pandemic is ongoing, and special effort must be paid to reduce the number of cancer patients receiving suboptimal treatment.
