Comparative Study
Plasma and salivary total antioxidant capacity in healthy controls compared with aggressive and chronic periodontitis patients.
To evaluate the plasma and salivary total antioxidant capacity (TAOC) in patients with generalized chronic periodontitis (CP), generalized aggressive periodontitis (AgP), and periodontally healthy controls. ⋯ Our results demonstrate that severe periodontitis may be associated with a lower plasma antioxidant capacity. The reduced antioxidant capacity in patients with severe periodontitis, especially with aggressive forms may be an important contributing factor to severe tissue destruction.

To identify Methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage status among medical students during their clinical rotations. ⋯ We found MRSA carriers among medical students at KAU, which showed a possible contribution of this group to transmit infection to hospitalized patients. Medical students must receive sufficient knowledge regarding control measures to avoid spread of this infection in hospitals.

To study the associations between hyperhomocysteinemia (HHcy) and the severity of coronary heart disease (CHD). ⋯ Hyperhomocysteinemia is independently associated with the severity of CHD, and significantly correlated with low status of folic acid and vitamin B12 in CHD patients.

Observational Study
The prevalence of thyroid cancer in patients with hyperthyroidism.
To determine the prevalence of thyroid cancer in patients with hyperthyroidism. ⋯ Many patients with hyperthyroidism in Muscat, Oman, especially those with Grave's disease, show malignancy, and hence a proper initial evaluation of these patients is required as part of long-term management.

Mucormycosis is an uncommon acute invasive fungal infection that affects immunocompromised patients. It progresses rapidly and has poor prognosis if diagnosed late. Early detection, control of the underlying condition with aggressive surgical debridement, administration of systemic and local antifungal therapies, hyperbaric oxygen as adjunctive treatment improves prognosis and survivability.
