Suppuration (pus formation), tissue death, auto-amputation of digits (via ainhum), and chronic lymphedema may also be seen.If the patient is not vaccinated, tetanus is often a complication due to secondary infection. Necrosis and gangrene are other common complications of severe infestation and superinfection. Staphylococcus aureus and Wolbachia endobacteria can be transmitted by the chigoe flea, as well as nearly 150 other different pathogens. For these reasons, the chigoe flea should be removed as soon as possible. Incubation
Because of the relatively rapid onset of tungiasis, the incubation period tends to be short. Although some reddening around the site of penetration occurs, the first symptoms are perceived in stage 2 as itching and severe pain, usually a day after penetration. Cause
Tungiasis is strictly caused by chigoe fleas (the term transmission does not apply because Tunga penetrans is itself responsible for the disease.) The preponderance of tungiasis lesions on the toes may be because chigoe flea is a poor jumper, attaining only a high of 20 cm. But the reality is more complex; for example, the jumping ability cannot explain why hands are the second-most affected body part. Lesions on the hands are better explained by playing in the sand and noting that hands are often used to remove sand from other parts of the body. The occurrence of tungiasis lesions on the toes, between them, and on the soles can be easily explained because most of the victims are poor, walk barefoot, and live in places where the sand (home to chigoe fleas) constitutes the floor.
Transition to adulthood
Although many childrens hospitals feature integrated multidisciplinary teams to coordinate healthcare of youth with spina bifida, the transition to adult healthcare can be difficult because the above healthcare professionals operate independently of each other, requiring separate appointments, and communicate among each other much less frequently. Healthcare professionals working with adults may also be less knowledgeable about spina bifida because it is considered a childhood chronic health condition. Due to the potential difficulties of the transition, adolescents with spina bifida and their families are encouraged to begin to prepare for the transition around ages 14–16, although this may vary depending on the adolescents cognitive and physical abilities and available family support. The transition itself should be gradual and flexible. The adolescents multidisciplinary treatment team may aid in the process by preparing comprehensive, up-to-date documents detailing the adolescents medical care, including information about medications, surgery, therapies, and recommendations. A transition plan and aid in identifying adult healthcare professionals are also helpful to include in the transition process.Further complicating the transition process is the tendency for youths with spina bifida to be delayed in the development of autonomy, with boys particularly at risk for slower development of independence. An increased dependence on others (in particular family members) may interfere with the adolescents self-management of health-related tasks, such as catheterization, bowel management, and taking medications.
