Thirty patients with systemic Candida infection underwent autopsy during a 13-year prospective study. Eleven patients had tissue-verified pulmonary candidiasis. Nine of these patients had hematogenous dissemination, as evidenced by multiple organ invasion; two had aspiration pneumonia with lung involvement only. Aspiration Candida pneumonia is rare. Pulmonary candidiasis usually arises from a focus of infection implanted during hematogenous dissemination. An infected indwelling venous catheter was the source of candidemia in six of these patients. Organisms in the lumen of pulmonary vessels caused a necrotizing vasculitis and appeared to invade the parenchyma from these areas.

A 95-year-old woman complained of sudden onset of disturbance of consciousness and right hemiparesis on April 20, 2003 and was admitted on the next day. She was drowsy and showed moderate right motor and sensory hemiparesis. The blood laboratory tests showed slight inflammatory reaction. A low density area was found in the left basal ganglia by brain CT, which was also coincided with the high signal region in T2, FLAIR and diffusion-MR images. The MRA of the intracerebral arteries presented no remarkable abnormality. The hemiparesis and impaired consciousness improved partially in the following week. However, she did not fully recover, since aspiration pneumonia and mild generalized inflammation continued. Percutaneous gastrostomy and intravenous hyperalimentation were started to improve her nutrition. The moderate inflammatory state persisted for several weeks. Her blood pressure suddenly fell and she died on June 12. Autopsy showed a mildly brownish and necrotic lesion from the left caudate to the putamen through the internal capsule. There was no liquefaction. On the microscopic examination, the necrosis surrounded by small vessels was consisted of numerous neutrophils and macrophages with pseudohypha and blastospore of candida. Small fragments of fungus were phagocytosed by macrophages. Small abscesses and necrotic foci due to candidiasis were observed in the bladder, kidneys, lungs, myocardium and thyroid gland. In this case, cerebral candidiasis probably occurred via hematogenous dissemination from a primary focus in the urinary tract. The intracerebral arteries revealed rather mild atherosclerotic changes and there was no occlusion by thromboembolism. Intracerebral lesion was diagnosed as candidiasis and there was no cerebral infarction by thromboembolism. If the infection occurred after cerebral infarction, there should not be any inflammatory reaction in the center of necrotic area. There have been few reports of cerebral candidal infection in patients without diabetes mellitus or immunosuppressive conditions. None of them had been diagnosed before death. Caution should be exercised for the presence of systemic candidiasis in elderly patients who are bedridden and with continuous low grade inflammatory reactions.

Oral health status declines with age and as a result the need for removable prostheses increases. Oral health is a reflection of one's general health, affecting the ability of an individual to eat and speak, and contributes significantly to a sense of confidence and well-being. Currently, there are 15 million denture wearers in the UK, representing a significant consumer base and a special healthcare consideration. The microbiology of denture plaque has received little attention in comparison with dental plaque, yet it differs in location and composition. Denture plaque and poor denture hygiene is associated with stomatitis (Candida infection), may also serve as a reservoir of potentially infectious pathogens, and may contribute to oral malodour and to caries and periodontitis in people who have remaining natural teeth. Oral bacteria have been implicated in bacterial endocarditis, aspiration pneumonia, gastrointestinal infection and chronic obstructive pulmonary disease, among others, and dentures offer a reservoir for microorganisms associated with these infections. An effective oral hygiene regimen is important to control denture plaque biofilm and contributes to the control of associated oral and systemic diseases.

An opportunistic pathogen, Candida is not only related to oral problems such as oral candidiasis and denture stomatitis, but also to systemic diseases such as aspiration pneumonia and fungemia. The carriage rate of Candida species in the oral cavity of individuals wearing dentures and with removable orthodontic appliances, has increased. Moreover, it is one of the causal pathogens in refractory infected root canals because of its resistance to antifungal drugs in root canal therapy and poses a great challenge during the treatment of patients. This problem has led to the search for alternative strategies for the treatment and management of C. albicans infections. In this mini review, recent preventive strategies against Candida infection in the oral mucosa with natural product-derived antifungal molecules were discussed. Inhibitory strategies by introducing competitive naturally-derived antifungal peptide molecules with Candida adhesion molecules were specifically introduced. In addition, novel sterilization methods for Candida-infected root canals and tooth structures in the oral cavity were considered, with focused attention on the activities of reactive oxygen species. The possibility of application of these novel strategies in clinical treatments and daily life was also proposed.

Crested screamers, a unique, mainly terrestrial avian species native to South America, are known to have a markedly high chick mortality rate in captivity, ranging from 61% to 94%; however, there is very limited information on this species' natural history within the literature, and even less about common diseases that affect them. Four captive-born crested screamer chicks (Chauna torquata) at a U.S. zoological institution died acutely from different causes over the course of 2.5 months. Although a hands-off approach was initially taken, each chick became acutely weak on exhibit and medical intervention was deemed necessary, but proved unsuccessful in all cases. Necropsy results of the chicks revealed various causes of death, including acute Escherichia coli colitis, aspiration pneumonia complicated by concurrent gastrointestinal Candidiasis, severe dehydration and emaciation, and acute amoebic gastroenteritis. No direct associations were found between these deaths and diet or husbandry; however, the limited literature on this topic suspects inadequate husbandry and immunosuppression to be the greatest cause of chick mortality in this species. The cases presented here are consistent with this hypothesis, but further exemplify the limited knowledge of this species and the need to optimize their survivability and proliferation in captivity.
