Introduction: Early repair in patients affected by myelomeningocele (MMC) is of paramount importance in order to prevent infection, minimize neural tissue damage, and reduce mortality. Treatment must include duraplasty and possibly an adequate soft tissue coverage. Delayed surgery in MMC patients can be more tedious due to the less clear borders between the placode and the skin. Moreover, the risks of wound infection and breakdown increase significantly. Case Presentation: We present the unusual case of a large MMC in a 3-year-old patient treated by combining the recently described cryopreserved amniotic membrane (AM) as homograft for dural reconstruction and a bilateral Keystone flap for soft tissue reconstruction. Discussion: Thanks to its anti-inflammatory and elastic proprieties, the AM can play an important role in preventing adhesion between the reconstructed layers, thus reducing the risk of spinal cord tethering. The Keystone flap, at the same time, allows the wound tension to be distributed widely over the flap margins and not only along the midline, which overlies the duraplasty, enhancing the scar quality and lowering the risk of cerebrospinal fluid recurrence and wound dehiscence, with no donor site morbidity.

Background Children with Sickle Cell Disease (SCD) may show growth failure in comparison to healthy peers. Many factors as hematological status, endocrine and/or metabolic dysfunction, and nutritional status, may play an important role in growth failure. The aim of this study was to assess whether impaired growth and nutritional intake can affect SCD severity during childhood. Methods We conducted an observational study on children with SCD referring to our clinic for routine follow-up visits in a 6-month period. We collected information on weight, height and body mass index (BMI) and calculated their respective standardized scores (z). The nutritional intake was assessed through the last 24-h recall intake of total calories, macro- (proteins, lipids, carbohydrates) and micronutrients (calcium, iron, phosphorus, vitamins B1, PP, A, C, B2). Disease severity was assessed through total hemoglobin (Hb) and fetal hemoglobin (HbF), and lactic dehydrogenase (LDH) levels, and through the total number and days of hospitalizations, as well as the lifetime episodes of acute chest syndrome (ACS). Results Twenty nine children (14 males, 15 females) with SCD were enrolled; their mean age was 9.95 years (SD 3.50, min 3.72, max 17.18). Z-weight and z-BMI were significantly directly related to total Hb. Food intake resulted significantly unbalanced in terms of total calorie intake, macro- and micronutrients, especially calcium, iron, vitamin B1 and C. Low intake of calcium and vitamin B1 were significantly inversely correlated with number and days of hospitalizations per year. Protein, lipid, phosphorus, and vitamin PP intakes resulted adequate but were inversely correlated with number and days of hospitalizations. Carbohydrate, lipid, iron, phosphorus, vitamins B1 and B2 intakes were significantly inversely correlated to HbF levels. Conclusions This study showed that, in our population, inadequate nutritional intake, weight and BMI have a significant impact on SCD severity indices.

Inhalation of a foreign body (FB) into the bronchial tree rarely occurs asymptomatically and, if leading to recurrent pneumonia, can be very difficult to diagnose. The present report deals with the case of a 10-year-old boy who had three episodes of pneumonia in the left lower lobe caused by the asymptomatic inhalation of a FB 12 months before. Standard thoracic CT, done during the third episode, revealed a slight reduction in the volume of the left lung with air bronchograms, multiple areas of bronchiectasis, and parenchymal consolidation of a segment of the lower lobe. Flexible fiberoptic bronchoscopy revealed a FB at the distal end of the left lower lobar bronchus, surrounded by granulation tissue and fully obstructing the anterior basal segmental bronchus. High-resolution CT (HRCT) images showed an inverted C-shaped image obstructing a bronchus. Removal of the FB was successful only with rigid bronchoscopy under total anesthesia. The FB was an air-pistol rubber bullet that the boy remembered playing with 12 months before. Two months after removal of the FB (ie, 14 months from its asymptomatic inhalation) and treatment with oral steroids, antibiotics, and respiratory physiotherapy, the patient recovered completely, and HRCT showed complete normalization of the lung. We conclude that, when the radiographic density of the FB is greater than the surrounding pulmonary parenchyma, HRCT can reveal the FB, and diagnostic flexible fiberoptic bronchoscopy can be avoided.

Most febrile convulsions (FC) in infants occur during a viral infection, particularly in children of less than 3 years of age; human herpesvirus 6 (HHV-6) has an important pathogenic role. To evaluate the link between this and other viruses and FC, a group of 65 children (mean age 18.46 months, SD +/- 9.19) with a first episode of simple FC (G1) was compared with 24 children (mean age 19.29 months, SD +/- 13.17) with a febrile syndrome but without FC (G2). Virological study showed the following infections: HHV-6 in 23/65 of G1 and in 12/24 of G2, adenoviruses (ADV) in 9/65 of G1 and in 0/24 of G2, syncytial respiratory virus (SRV) in 3/28 of G1 and in 0/2 of G2, HSV-1 in 6/65 of G1 and in 1/24 of G2, cytomegalovirus (CMV) in 2/65 of G1 and in 0/24 of G2 and HHV-7 in 1/42 of G1 and in 1/13 of G2. Children in G1, statistically compared with G2, were significantly more likely to have a family history of FC and circulating granulocytes, while IgM and alpha 2-globulin were less probable. Some cytokines (IL 1 beta, TNF beta and GM-CSF) were found in 24 children in G1 and 12 in G2; no differences were found between the two groups. In the light of our data and of the recent literature, the possibility that the cytokines may act on the nervous system cannot be excluded. Among the HHV-6-infected children, those suffering from convulsions were statistically more likely to have a family history of FC and IgM, while IgA were less likely. In G1, 57 cases were followed up over 2 years: 9 of them had a second episode of FC. Virological diagnosis at the first episode of FC revealed HHV-6 infection in 3 cases, 2 of these being due to viral reactivation. We underline the important role of HHV-6 infection in FC and postulate a relationship between family history and the immunity of the patient; this is confirmed by the loss of statistical significance in the reduction of IgM in G1 compared with G2 with no family history of FC. The reactivation of FC by HHV-6 is a possibility to be borne in mind; an increased number of cases would be needed to confirm this hypothesis.
