The diagnosis of a pustular dermatosis occurring during the first months of life is usually based on clinical findings. However, some cases may require simple investigations including microscopic examination of pustular content, cultures, and skin biopsies. The main benign transient neonatal types of pustulosis include erythema toxicum neonatorum, infantile acropustulosis, transient neonatal pustular melanosis, and neonatal acne. The most common causes of infectious pustular skin lesions include bacterial infections, which may be initially localized (Staphylococcus aureus) or septicemic (with Listeria monocytogenes as the leading causitive agent); viral infections (herpes simplex, varicella-zoster, and cytomegalovirus infections); fungal infections (candidiasis); or parasitic disorders (scabies). The main objective of this article is to propose a systematic approach to pustular eruptions in the neonate. The need for investigating every neonate with pustules for an infectious disease is emphasized. The Tzanck smear, the Gram's stain, and a potassium hydroxide preparation are the most important quick diagnostic tests. The Tzanck smear is a very easy, rapid, and sensitive test for detection of a herpetic infection (multinucleated giant cells) as well as noninfectious pustular eruptions (eosinophils, neutrophils). Therefore the Tzanck smear should be the first test performed. Moreover, a Gram's stain and potassium hydroxide preparation should be performed in cases of neonatal pustular disorders to detect bacterial and fungal infections. The goal of this diagnostic approach is to spare a healthy neonate with a benign transient condition an invasive evaluation for sepsis, potentially harmful antibiotic therapy, and prolonged hospitalization, with its own inherent morbidity.

Following trauma, there is an increase of Th2 cytokines (IL-4, IL-6, and IL-10) and a decrease in Th1 cytokines (IFN-gamma and IL-2) that may account for impaired cellular immunity. However, the functional significance of a dominant Th2 pattern to the host remains unclear. The aim of this study was to evaluate whether Candida albicans (CA) sepsis in the setting of a Th2 response to trauma leads to increased mortality and to examine the mediators involved. Female BALB/c mice were randomized (12 per group) to receive no injury (C); trauma, consisting of a combined femur fracture and 40% total blood loss (T); no injury plus CA infection (C+CA); and CA infection 1 week following trauma (T+CA). Survival was then followed for 3 weeks. In a separate study, mice were treated as above (5 per group) and sacrificed. Harvested splenocytes were evaluated for concanavalin A-stimulated cytokine production and liver and kidney homogenates were plated to evaluate CA growth per organ and examined histologically. Candida infection at 1 week following trauma resulted in significantly increased mortality compared to infected controls. Furthermore, the Th2 dominant cytokine pattern was significantly augmented in the presence of CA infection in both C+CA and T+CA groups. Additional analysis showed significant growth of CA in liver and kidney homogenates from T+CA compared to C+CA mice. These results suggest that injured and infected mice demonstrate augmentation of Th2 dominant responses above that of injury or infection alone, as well as a decreased ability to clear Candida which may partially explain the increase in mortality observed. Therapies designed to neutralize Th2 cytokines or augment Th1 cytokines may prove beneficial in the setting of sepsis following trauma.

We describe congenital cutaneous candidiasis (CCC) in a term newborn. The mother had candidal vaginitis 1 week before delivery. At birth, the infant had a generalized, intensely erythematous, papulovesicular eruption, respiratory distress and elevation of liver function tests. The child responded well to intravenous amphotericin B plus topical and oral nystatin. There have been 13 previously reported cases of CCC in infants weighing more than 1500 gm who had evidence of systemic infection. Two deaths were attributed to candidal pneumonia and sepsis. The majority of infants with CCC have infection localized to the skin, but if there is any evidence of respiratory distress or signs of sepsis the possibility of systemic candidiasis and the need for parenteral antifungal therapy must be considered.

Systemic Candida infections are usually encountered as opportunistic infections in a setting of immunologic depression. Sepsis or arthritis due to Candida is not expected in healthy people. Epstein-Barr virus may infect B cells, but does not cause immunosuppression of any clinical significance. As far as we know, invasive non-albicans Candida infection complicating Epstein-Barr virus infection has not been reported in previously healthy children. In this report, two previously healthy children, one with sepsis due to Candida species and the other sepsis and arthritis due to Candida parapsilosis are described. Both patients were male and were aged 2 and 9 y. The diagnosis was confirmed by culture. Both children also had coincidental acute Epstein-Barr virus infection, confirmed by Epstein-Barr virus viral capside antigen-IgM. They were both cured with fluconazole given for 21 days and 48 days, respectively.

A retrospective review of 100 liver transplantations in 98 children was performed to determine the incidence of infection caused by Candida organism in these patients and to identify risk factors that may predispose to serious fungal infection. Thirty-one infections caused by Candida organisms developed during the initial 28 days posttransplantation: 19 were definite invasive infections (one deep site or one positive blood culture), 2 were probable invasive infections (three superficial sites), and 10 were urinary tract infections. Eleven of 19 patients had fungemia or a disseminated infection (two noncontiguous deep organs involved and/or positive blood cultures) and 8 of 19 had peritoneal candidiasis. Infection caused by Candida organisms was a contributing factor to mortality in 7 of 21 patients (case fatality rate of 33%) with invasive infection. Risk factors that were predictive for invasive infection by univariate analysis included the following: pretransplantation antibiotic therapy, length of transplant operation, transfusion requirement, number of days in the intensive care unit, number of days intubated, number of concurrent bacterial infections, number of antibiotics administered, number of laparotomies performed posttransplantation, retransplantation, hepatic artery thrombosis, bile leaks, and renal and respiratory failure. By logistic regression analysis, bile leak, hepatic artery thrombosis, preoperative steroid use, transfusion requirement, and the number of days intubated were identified as independent risk factors for invasive infection caused by Candida organisms. The use of prophylactic antifungal agents in high-risk patients may be important in reducing the serious morbidity and mortality associated with sepsis caused by Candida organisms in pediatric liver transplant recipients.

We investigated the prophylactical administration of liposomal amphotericin B (Ambisome) in the early phase after liver transplantation (LTx). Fifty-eight patients received Ambisome prophylactically after LTx. Ambisome (1 mg kg-1 day-1) was given intravenously for 7 days after LTx. Immunosuppressive prophylaxis was cyclosporin A (CsA) based in 11 patients. Forty-seven patients had a tacrolimus-based immunosuppressive regimen. CsA and tacrolimus dosages were adjusted to trough levels of 150-250 ng ml-1 (EMIT) and 5-15 ng ml-1 (MEIA II) respectively. Three patients died from sepsis due to Aspergillus fumigatus infection. Reasons for a fatal outcome were foudroyant Aspergillus pneumonia in a patient transplanted for fulminant hepatic failure on post-operative day (pod) 8; Aspergillus sepsis with severe endocardidtis in a patient with two retransplantations for graft non/dysfunction on pod 24; and disseminated aspergillosis due to Aspergillus fumigatus in a patient retransplanted for primary non-function (pod 19). All three patients underwent haemofiltration for renal failure. One patient with Candida albicans sepsis (pod 4) recovered under increased dosage of Ambisome (3 mg kg-1 per day). Ambisome (1 mg kg-1 per day) seems to be beneficial against systemic Candida infections. However, the onset of systemic Aspergillus infections could not be prevented. Obviously, higher Ambisome doses appear to be necessary against Aspergillus. We recommend the use of Ambisome (3 mg kg-1 per day) for patients with risk factors such as graft dys-/non-function, retransplantation, haemofiltration and complicated acute liver failure to prevent invasive aspergillosis.

We describe a term infant with congenital cutaneous candidiasis (CCC), and review all cases in the English literature that reported birth weight and outcome. Presence of an intrauterine foreign body was a predisposing factor for development of CCC and subsequent preterm birth. The most common presentation of CCC in neonates weighing >1000 g was a generalized eruption of erythematous macules, papules, and/or pustules that sometimes evolved to include vesicles and bullae. Extremely low birth weight, premature neonates weighing <1000 g most often presented with a widespread desquamating and/or erosive dermatitis (10 of 15 [67%]), and were at greater risk for systemic infection with Candida spp (10 of 15 [67%]) and death (6 of 15 [40%] than those weighing >1000 g (5 of 48 [10%]; 4 of 48 [8%], respectively). Systemic antifungal therapy is recommended for neonates with burn-like dermatitis attributable to Candida spp, or positive blood, urine, and/or cerebrospinal fluid cultures. Systemic treatment also should be considered for all infants with CCC who have respiratory distress in the immediate neonatal period and/or laboratory signs of sepsis such as an elevated leukocyte count with an increase in immature forms or persistent hyperglycemia and glycosuria.

Deep-seated Candida infections are challenging to diagnose by noninvasive means, and new modalities are needed to improve the yield of such investigations. Reported here is a case of Candida tropicalis vertebral osteomyelitis complicating epidural catheterisation in a diabetic patient with complicated abdominal sepsis. The diagnosis was supported by detection of increased D-arabinitol/L-arabinitol ratios in urine samples, and failure of medical management was indicated by elevated D-arabinitol/L-arabinitol ratios, which later decreased to baseline with successful surgical debridement and prolonged antifungal therapy.

An autopsy case of chronic mucocutaneous candidiasis (CMCC) is reported here, in which cerebral vasculitis developed in the final stage. A 32-year-old man who had suffered from superficial candidial infection since his childhood was diagnosed as having CMCC. During the past 7 years the patient had developed various associated disorders including insulin-dependent diabetes mellitus (IDDM), common variable immunodeficiency (CVID), candidial esophagitis, multiple digestive tract ulcers and pyothorax. In 1998, at the age of 32, he developed convulsions that were accompanied by impairment of consciousness, and which were temporarily treated with steroid pulsed-medication. Epileptic status associated with widespread cerebral infarctions occurred subsequently, however, and the patient died of sepsis 2 months later. At autopsy, multiple cerebral infarctions and arterial thrombosis were evident. These were histologically proven to be primary vasculitis which was confined solely to the brain, and this was verified by general pathological examination. Thus, some as yet unknown cerebrovascular factors might be involved in the onset of an autoimmune-related vasculitis in patients with a longstanding immunodeficiency state such as CMCC.

Recently, new broad spectrum carbapenem has been investigated on a world-wide scale for the treatment of moderate to severe infections. In the neonatal intensive care units the extensive use of third generation cephalosporins for therapy of neonatal sepsis may lead to rapid emergence of multiresistant gram-negative organisms. We report the use of meropenem in 35 infants with severe infections due to Acinetobacter baumanii and Klebsiella pneumoniae. All gram negative bacteria were resistant to ampicillin, amoxicillin, ticarcilin, cefazoline, cefotaxime, ceftazidime, ceftriaxone and aminoglycosides. Eighty two percent of the cases (29/35) were born prematurely. Assisted ventilation was needed in 85.7% (30/35). All infants deteriorated during their conventional treatment and were changed to meropenem monotherapy. Six percent (2/35) died. The incidence of drug-related adverse events (mostly a slight increase in liver enzymes) was 8.5%. No adverse effects such as diarrhea, vomiting, rash, glossitis, oral or diaper area moniliasis, thrombocytosis, thrombocytopenia, eosinophilia and seizures were observed. At the end of therapy, overall satisfactory clinical and bacterial response was obtained in 33/35 (94.3%) of the newborns treated with meropenem. Clinical and bacterial response rates for meropenem were 100% for sepsis and 87.5% for nosocomial pneumonia. This report suggests that meropenem may be a useful antimicrobial agent in neonatal infections caused by multiresistant gram negative bacilli. Further studies are needed to confirm these results: Meropenem, newborn, sepsis and nosocomial infection.
