Pilonidal sinus disease (PSD) is common in adults, but it may also develop in adolescents. The intergluteal groove is a deep moist area in which broken hairs and foreign bodies can collect, often leading to infection. Only a few papers have been published considering PSD in children. For the present study, we retrospectively examined the data of operated patients with PSD. From that review, it appears that high body mass index (BMI) might be a risk factor for the development of PSD and its complications in older children. Fourteen young patients (12 males, 2 females, 12-18 years of age) underwent surgery for PSD. According to the BMI-for-age, eight of these patients (57, 1%) were overweight or obese. Five of them (35.8%) developed mild to moderate postoperative complications. Symptoms recurred in one patient (7.1%) whose BMI was considered as overweight. In patients with normal weight no early or late complications developed. Our findings suggest that high BMI in adolescents is a significant risk factor in the development of both symptoms and complications of PSD after surgical treatment.

Preoperative MRCP using a respiratory navigator-triggered T2-weighted TSE sequence with a PACE technique accurately depicts the biliary anatomy in LDLT donors and may guide intraoperative management of the biliary tract.

HT is a frequent cardiovascular risk factor in liver transplant recipients. However, there are only few studies in the literature regarding the risk of HT in liver transplanted children. The aim of this study was to assess the 24 h BP profiles of liver transplanted patients and to compare the results with healthy children. ABPM was performed on 20 liver transplanted patients and 27 healthy children aged 7.1 ± 4.8 and 8.5 ± 2.9 yr, respectively. HT was defined as SDS > 1.64 (i.e., >95th percentile) adjusted for gender and height. The mean duration of post-transplant follow-up was 32 ± 19 months. Six (30%) patients were found to be hypertensive. The physiological nocturnal BP fall was attenuated significantly in the study group for diastolic BP (11.5 ± 6.1 mmHg vs. 17.7 ± 7.1 mmHg, p = 0.006). Specifically, the number of patients with high nighttime systolic and diastolic BP SDS (p = 0.02 and p = 0.004, respectively) as well as elevated nighttime systolic (p = 0.03) and diastolic (p = 0.003) BPLs was found to be significantly higher than those in the controls. Alteration of the "normal" circadian rhythm is very frequent in liver transplant recipients. Thus, it is recommended to perform ABPM on all liver transplanted children not to underdiagnose HT.
