Prickly heat is a benign cutaneous manifestation due to the obstruction of the sweat ducts following excessive exposure to heat, humidity or hyperthermia. We report the case of a 70-year old diabetic female patient treated with insulin, hospitalized in the Intensive Care Unit due to acidocetosic coma secondary to pyelonephritis. The patient had diffuse clear vesicular lesions spread all over the body,(a) firm to palpation, on a healthy skin, suggesting miliaria crystallina. Miliaria crystallina is a benign cutaneous manifestation due to sweat retention secondary to obstruction of the sweat ducts. It is possible to distinguish between miliaria crystallina due to the obstruction in the stratum corneum, miliaria rubra due to the obstruction within the malpighian stratum and miliaria profunda due to an obstrusction in or below the dermoepidermal junction, depending on the level of obstruction. Miliaria crystallina heals spontaneously in a few hours giving rise to a desquamation, as occurred in our patient after regression of febrile syndrome.

Fox-Fordyce disease is a relatively infrequent pathology of the apocrine glands that affects almost exclusively young women. The disease is characterized by the presence of pruritic follicular papules mainly in the armpits that respond poorly to treatment and severely affect the patient's quality of life. We report two cases with clinical diagnosis and histopathological confirmation, presenting perifollicular xanthomatosis on histological examination, recently described as a distinctive, consistent, and specific feature of this disease.

BACKGROUND
The role of sweat gland in inflammation has not received sufficient attention. The thermal stress during the summer months in tropical areas provides an opportunity to study the morphological patterns of inflammation produced primarily by the sweat gland.
AIM
To collect clinical data on sweat-induced dermatitis during the summer months.
METHODS
A hospital-based descriptive cross-sectional study was done during the hot and humid summer months of April to June in a tertiary care institute in Puducherry. Patients clinically diagnosed with sweat-induced dermatitis (dermatitis primarily due to retention or extravasation of sweat) were included in the study. A detailed history was taken, and clinical examination was done.
RESULTS
One hundred and fifty patients were included in the study. Various typical and atypical manifestations of sweat-induced dermatitis were seen. "Sweat dermatitis" presenting with dry, hyperpigmented, fissured "parchment"-like skin, shiny "crinkled cellophane paper"-like skin, or asymptomatic hyperpigmented macules was seen. Other atypical presentations included miliaria pustulosa with "hypopyon sign" and "linear and parallel ridge pattern" of dermatitis in patients with miliaria rubra affecting the lower neck and upper chest.
CONCLUSION
A wide spectrum of sweat-induced dermatitis was seen during the summer months in a tropical region. It reflects the role of the sweat gland in cutaneous inflammation. An increased awareness of atypical manifestations is needed.

A 3-year-old Japanese boy presented with a 3-month history of itchy erythematous papules on his trunk and forearms, the histologic findings of which were characterized by predominantly neutrophilic inflammation within and around the eccrine sweat ducts and obliteration and disruption of the superficial eccrine sweat ducts. Although the skin disorder had some clinical and histopathologic similarity to miliaria and neutrophilic eccrine hidradenitis, it was ultimately conformed to be neither disorder. Based on this and a case report in the Japanese literature of a 1-year-old boy with erythematous eruptions whose clinical and histopathologic findings were similar to those in our case, we propose the skin disorder in our case, referred to as "neutrophilic superficial eccrine ductitis," as a unique entity.

Fox-Fordyce disease (FFD), also known as apocrine miliaria, is a rare and chronic skin disease characterized by itching and skin-colored, light brown or yellowish papules. FFD typically affects postpubertal young women between 13 and 35 years. The etiology is not completely known, but a hormonal component is in discussion. Furthermore, exacerbating factors like laser hair removal and hyperhidrosis have been described. Treatment of FFD is quite challenging, as the reported modalities mostly show limited success.

Review
BACKGROUND
Biofilms are diverse groups of microorganisms encased in a self-produced matrix that offers protection against unfavorable conditions and antibiotics.
METHODS
We performed a literature search using the MEDLINE electronic database. Only original articles published in English were considered for review.
RESULTS
Biofilms have been implicated in the pathogenesis of acne, eczema, hidradenitis suppurativa, onychomycosis, miliaria, and impetigo. Adverse dermal-filler reactions are also linked to biofilms. Strict aseptic technique and prophylactic antibiotics are recommended in order to avoid such complications. Finally, biofilms are implicated in wounds, mainly chronic and diabetic, where they impede healing and cause recurrent infections. Several novel anti-biofilm agents and wound debridement have been shown to be beneficial.
CONCLUSIONS
Biofilms are a significant cause of disease with wide implications in the field of dermatology. Several novel treatments have been found to be effective against biofilms, depending on the underlying microbes and type of disease.
