An 18-month-old neutered male labradoodle was treated with surgical debridement for maxillary osteomyelitis and sequestrum formation. Histopathologic findings of the necrotic bone were consistent with Cryptococcus subspecies, confirmed with latex agglutination serum titer testing. The patient responded to a combination of fluconazole and surgical debridement and was titer negative after 8 months of medical therapy. The patient never exhibited signs of systemic illness which is commonly reported with cryptococcosis. Cryptococcus subspecies infection in dogs in the Pacific Northwest is part of an ongoing outbreak in the region, first reported in 2001, and is associated with specific risk factors. This is the first published case of oral cryptococcosis from primary inoculation.

Oroantral fistula (OAF) represents the pathological communication between the oral cavity and maxillary sinus. This condition arises when the structural integrity of the maxillary sinus floor is compromised, resulting in a direct conduit between the sinus and the oral cavity. A less prevalent yet clinically significant contributor to the formation of OAF is chronic osteomyelitis of the maxilla.

Article Synopsis
- - A 61-year-old male with diabetes and hypertension experienced severe facial pain due to complications from COVID-19, including osteomyelitis affecting his frontal sinus and upper jaw.
- - Imaging revealed thickening of the maxillary sinus and several damaging lesions in the frontal sinus, which led to brain abscesses identified through culture tests.
- - The treatment included antibiotics and surgery (trephination and drainage), along with other medications and sessions in a hyperbaric chamber to promote healing.

Article Synopsis
- - The study examined 50 mucormycosis patients at a Chennai tertiary care center, focusing on their symptoms, duration, progression, and comorbidities.
- - CT and MRI scans assessed facial bone involvement, revealing that the nasal cavity and maxillary sinuses were the first affected, with severe cases leading to complications like rhino-orbito-cerebral infection and bone erosion.
- - Out of the patients, 22 experienced facial bone involvement requiring surgical debridement; aggressive treatment is essential due to the infection’s high mortality rate, emphasizing the need for early diagnosis and intervention.

Background: Early diagnosis of neonatal osteomyelitis is often challenging due to the rarity of such cases and here we are presenting 2 case reports to add to the existing deficient literature: A 15-day-old male infant presented with swelling and pus discharge from the anterior region of the mandible. Repeated culture and sensitivity tests revealed a transition from disseminated methicillin-sensitive S. aureus sepsis to methicillin-resistant sepsis.
