title: Analytical study of pustular eruptions in neonates.
abstract: Pustular eruptions are commonly encountered in neonatal practice. Much confusion exists among clinicians because of the similarity in clinical lesions, paucity of relevant literature, and varied nomenclature used for these diseases. This often results in inappropriate diagnoses and therapies, besides subjecting the neonates to invasive and traumatic investigative procedures. We conducted a comprehensive study of pustular eruptions in 100 neonates, using the clinical examination and simple laboratory tests to arrive at a practical diagnostic and therapeutic approach to this problem. Of the 100 neonates with pustular eruptions, 36% were in the early neonatal period (first week of life). A slight male preponderance with a male:female ratio of 1:0.79 was observed. The majority of the families of these infants had poor socioeconomic status (96%) and were living in slums (71%). A study of their educational status revealed that 54% of the mothers were uneducated. Fifty-seven percent of the neonates were born at home. The clinical pattern of diseases among these neonates was that 58% of them had infections [impetigo (23%), intertrigo (14%), scabies (6%), and viral diseases (6%)]. Noninfectious diseases (42%) included miliaria pustulosa, erythema toxicum neonatorum, epidermolysis bullosa, and contact dermatitis. Simple laboratory investigations helpful in establishing the diagnosis were smears processed with Gram (24%) and Giemsa (39%) stains and wet mounts with 10% potassium hydroxide (KOH) solution (27%) for direct microscopic examination. More than half (53%) of the patients required no specific treatment except for counseling and medications to alleviate symptoms, while others with an infectious etiology responded to topical and or systemic antibiotics/antifungals. Pustular eruptions in neonates include both infectious and noninfectious diseases. Simple laboratory tests such as Gram- and Giemsa-stained smears, direct microscopy with 10% KOH wet mounts, bacterial and fungal cultures are helpful in establishing the diagnosis and occasionally skin biopsy is needed. A practical diagnostic and therapeutic approach to this problem is discussed.
