Chronic maxillary sinusitis and diabetes related maxillary osteonecrosis: a case report

Dental infections and maxillary sinusitis are the main causes of osteomyelitis. Osteomyelitis can occur in all age groups, and is more frequently found in the lower jaw than in the upper jaw. Systemic conditions that can alter the patient's resistance to infection including diabetes mellitus, anemia, and autoimmune disorders are predisposing factors for osteomyelitis. We report a case of uncommon broad maxillary osteonecrosis precipitated by uncontrolled type 2 diabetes mellitus and chronic maxillary sinusitis in a female patient in her seventies with no history of bisphosphonate or radiation treatment.

Acute Fascial Space Abscess upon Dental Implantation to Patients with Diabetes Mellitus

As popularity of dental implantation is increasing, the number of cases associated with complications also increase. Evaluation on diabetes mellitus is often neglected due to the disease's irrelevance to implantability. However, patients with diabetes mellitus are susceptible to infection due to impaired bactericidal ability of neutrophils, cellular immunity and activity of complements. Due to this established connection between diabetes mellitus and infection, a couple of cases were selected to present patients with diabetes mellitus with glycemic incontrollability, suffering from post-implantation dentigerous inter-fascial space abscess.

Major Hepatectomy in the HCC Patient with an Indocyanine Green Retention Rate at 15 Minutes of 10% or Higher: Predictive Values of Postoperative Hepatic Failure

PURPOSE: Major hepatic resection is sometimes inevitable in patients with impaired liver function. We evaluated risk factors that cause postoperative liver failure after major hepatic resection in patients with over a 10% Indocyanine Green Retention rate at 15 minutes (ICGR15). METHODS: From Apr. 2002 to Aug. 2009, 32 patients who had over a 10% rate of ICGR15 underwent major hepatic resection (> or =4 Couinaud segments). Among the 32, 9 patients showed postoperative liver failure (less than 50% prothrombine time and/or 5 mg/dl or higher of total bilirubin). This high-risk group was compared to the rest who constituted a low-risk group. RESULTS: Patients with esophageal varix were more common in the high risk group (4 versus 2, p=0.043). Other clinicopathologic features showed no difference between the two groups. We had 2 in-hospital deaths in the high risk group. CONCLUSION: Great care is needed in patients with esophageal varix and limited liver function during major hepatic resection.
