Pyromania moved from the DSM-4 chapter "Impulse-Control Disorders Not Otherwise Specified," to the chapter "Disruptive, impulse-control, and conduct disorders" in DSM-5. Signs and symptoms
According to DSM-5, there are six signs of pyromania. Pyromania is mainly categorized by the purposeful setting of fire, tension or arousal before a fire is set, interest in or attraction to fire, and pleasure or relief after setting a fire. These fires not set for personal gain, are not meant to express anger or conceal illegal activity, are not in support of sociopolitical ideologies, are not in response to delusions, and are not signs of intellectual disability. For diagnosis, the setting of fire should not be better explained by a conduct disorder, manic episode, or a personality disorder (antisocial personality disorder). ICD-11 also adds substance abuse to this list. According to ICD-11, signs of fire setting may occur "in response to feelings of depressed mood, anxiety, boredom, loneliness, or other negative affective states." Those with pyromania exhibit problems in social environments and learning disabilities. Women pyromaniacs "often report histories of exposure to trauma, including sexual abuse, and self-harm." Episodic fire setting may become more intense and violent over time, becoming potentially chronic if untreated. Causes
Most studied cases of pyromania occur in children and teenagers. There is a range of causes, but an understanding of the different motives and actions of fire setters can provide a platform for prevention. Common causes of pyromania can be broken down into two main groups: individual and environmental.
Also, there are several skin diseases that can cause an intertrigo to develop, such as dermatitis or inverse psoriasis. Bacterial
Bacterial intertrigo can be caused by Streptococci and Corynebacterium minutissimum. Diagnosis
Intertrigo can be diagnosed clinically by a medical professional after taking a thorough history and performing a detailed physical examination. Many other skin conditions can mimic intertrigos appearance including erythrasma, inverse psoriasis, scabies, pyoderma, atopic dermatitis, candidiasis, seborrheic dermatitis, and fungal infections of the superficial skin caused by Tinea versicolor or Tinea corporis. Treatment
Intertrigo is treated by addressing associated infections, by removing moisture from the site, and by using substances at the site to help maintain skin integrity. If the individual is overweight, losing weight may also help. Relapses of intertrigo are common.Keeping the area of the intertrigo dry and exposed to the air can help prevent recurrences, as can removing moisture from the area using absorbent fabrics or body powders, including plain cornstarch and judiciously used antiperspirants.Greases, oils, and barrier ointments  may help by protecting skin from moisture and from friction. Antifungal powders, most commonly clotrimazole 1%, may also be used in conjunction with a barrier ointment. Diaper rash ointment can also help.Fungal infections associated with intertrigo may be treated with prescription antifungals applied directly to the skin (in most cases) or systemic antifungals, including fluconazole, nystatin, and griseofulvin.Intertrigo is also a known symptom of vitamin B6 deficiency.
