Computed tomography
Where it is readily available, computed tomography (CT) has become frequently used, especially in people whose diagnosis is not obvious on history and physical examination. Although some concerns about interpretation are identified, a 2019 Cochrane review found that sensitivity and specificity of CT for the diagnosis of acute appendicitis in adults was high. Concerns about radiation tend to limit use of CT in pregnant women and children, especially with the increasingly widespread usage of MRI.The accurate diagnosis of appendicitis is multi-tiered, with the size of the appendix having the strongest positive predictive value, while indirect features can either increase or decrease sensitivity and specificity. A size of over 6 mm is both 95% sensitive and specific for appendicitis.However, because the appendix can be filled with fecal material, causing intraluminal distention, this criterion has shown limited utility in more recent meta-analyses. This is as opposed to ultrasound, in which the wall of the appendix can be more easily distinguished from intraluminal feces. In such scenarios, ancillary features such as increased wall enhancement as compared to adjacent bowel and inflammation of the surrounding fat, or fat stranding, can be supportive of the diagnosis. However, their absence does not preclude it. In severe cases with perforation, an adjacent phlegmon or abscess can be seen. Dense fluid layering in the pelvis can also result, related to either pus or enteric spillage. When patients are thin or younger, the relative absence of fat can make the appendix and surrounding fat stranding difficult to see.
The characteristics (such as morphology and colour) of the colonies may allow initial diagnosis of the organism causing disease symptoms. Respiratory, gastrointestinal, and esophageal candidiasis require an endoscopy to diagnose. For gastrointestinal candidiasis, it is necessary to obtain a 3–5 milliliter sample of fluid from the duodenum for fungal culture. The diagnosis of gastrointestinal candidiasis is based upon the culture containing in excess of 1,000 colony-forming units per milliliter. Classification
Candidiasis may be divided into these types:

Mucosal candidiasis
Oral candidiasis (thrush, oropharyngeal candidiasis)Pseudomembranous candidiasis
Erythematous candidiasis
Hyperplastic candidiasis
Denture-related stomatitis — Candida organisms are involved in about 90% of cases
Angular cheilitis — Candida species are responsible for about 20% of cases, mixed infection of C. albicans and Staphylococcus aureus for about 60% of cases. Median rhomboid glossitis
Candidal vulvovaginitis (vaginal yeast infection)
Candidal balanitis — infection of the glans penis, almost exclusively occurring in uncircumcised males
Esophageal candidiasis (candidal esophagitis)
Gastrointestinal candidiasis
Respiratory candidiasis
Cutaneous candidiasis
Candidal folliculitis
Candidal intertrigo
Candidal paronychia
Perianal candidiasis, may present as pruritus ani: 309 
Candidid
Chronic mucocutaneous candidiasis
Congenital cutaneous candidiasis
Diaper candidiasis: an infection of a childs diaper area: 309 
Erosio interdigitalis blastomycetica
Candidal onychomycosis (nail infection) caused by Candida
Systemic candidiasisCandidemia, a form of fungemia which may lead to sepsis
Invasive candidiasis (disseminated candidiasis) — organ infection by Candida
Chronic systemic candidiasis (hepatosplenic candidiasis) — sometimes arises during recovery from neutropenia
Antibiotic candidiasis (iatrogenic candidiasis)

Prevention
A diet that supports the immune system and is not high in simple carbohydrates contributes to a healthy balance of the oral and intestinal flora. While yeast infections are associated with diabetes, the level of blood sugar control may not affect the risk.
