BACKGROUND Intraoperative ultrasound is a routine procedure in abdominal surgery. Not only detection of focal lesions but also perfusion and elasticity analyses using color-coded Doppler sonography, contrast-enhanced ultrasound and elastography enable highly sensitive and highly specific diagnostics, especially in oncological surgery. Apcin OBJECTIVE This article provides an overview on current techniques of intraoperative ultrasound and gives an outlook on future possibilities and applications. MATERIAL AND METHODS Literature-based presentation of evidence-based intraoperative ultrasound, discussion of current basic research and expert recommendations. RESULTS Modern intraoperative ultrasound is a highly efficient technique for detection and characterization of focal space-occupying lesions in surgery of benign and malignant diseases. CONCLUSION Intraoperative ultrasound is a highly sensitive and specific diagnostic tool, providing real-time diagnostics with a manageable amount of technical equipment. Thus, preoperative diagnostics can be refined, partly resulting in a modification of intraoperative treatment management. Future developments in the fields of digital image fusion with preoperative sectional imaging, optical guidance of surgical instruments and molecular targeted tumor therapy will increase the importance of intraoperative sonography even more.BACKGROUND Septopreoptic holoprosencephaly is a mild form of holoprosencephaly in which the midline non-separation is restricted to the septal or preoptic regions. This entity has only been described in a small case series in which associated intracranial abnormalities were limited to the midline structures. OBJECTIVE To describe the radiologic findings of septopreoptic holoprosencephaly and highlight that it can be associated with a variety of intracranial abnormalities, not merely with abnormalities restricted to midline structures as previously reported. MATERIALS AND METHODS We retrospectively identified 22 children whose MRIs were confirmed to have non-separation restricted to the septal and preoptic region, fulfilling the criteria for septopreoptic holoprosencephaly. We then categorized MRIs as having, in addition, either intracranial abnormalities limited to the midline structures or major abnormalities not limited to the midline structures. RESULTS Five children had intracranial abnormalities limited to the midline structures. Seventeen children had major intracranial abnormalities not limited to the midline structures. The major abnormalities included patterning defects of the midbrain-hindbrain (elongated midbrain, shortened pons, shortened/elongated medulla, partial rhombencephalosynapsis), bilateral perisylvian polymicrogyria, microcephaly, megalencephaly and a spheno-ethmoidal encephalocele. Recognized syndromes/chromosomal abnormalities were also observed in this patient group. CONCLUSION Our results suggest that septopreoptic holoprosencephaly has been under-recognized and under-reported to date. We propose that searching for this anomaly should be part of the complete assessment of the midline in all children undergoing brain MRI for intracranial malformations.Rehospitalization following pediatric heart transplantation is common. However, existing data remain somewhat limited. Using a novel linkage between administrative and clinical databases, pediatric heart transplant (HT) recipients from 29 centers who survived to discharge were retrospectively reviewed to determine the frequency, timing of, and indication for all-cause rehospitalizations in the year following transplant discharge. Of 2870 pediatric HT recipients, 1835 (63.9%) were rehospitalized in the first year post-discharge (5429 total readmissions). Rehospitalization rates varied significantly across centers (46% to 100%) and were inversely correlated to center transplant volume (r2 0.25, p  less then  0.01). The median number of rehospitalizations per patient was 2 (IQR 1-4) and the median time to first rehospitalization was 29 days (IQR 9-99 days). Independent risk factors for rehospitalization included younger age at HT (HR 0.99, 95% CI 0.97-0.99), congenital heart disease (HR 1.2, 95% CI 1.1-1.4), listing status 1B at transplant (HR 1.3, 95% CI 1.1-1.5), and post-transplant complications including rejection prior to discharge (HR 1.5 95% CI 1.3-1.8) and chylothorax (HR 1.3, 95% CI 1.0-1.6). Cardiac diagnoses were the most common indication for rehospitalization (n = 1600, 29.5%), followed by infection (n = 1367, 25.2%). These findings may serve to guide the development of interventions aimed at reducing post-HT hospitalizations.INTRODUCTION Robot-assisted simple prostatectomy (RASP) is a relatively new minimally invasive procedure for surgical treatment to manage symptomatic, therapy-refractory benign prostate hyperplasia (BPH) in prostate volumes >80 cm3. Thus, postoperative morbidity based on Clavien-Dindo and hematological parameters in RASP and open simple prostatectomy (OSP) procedures are examined. PATIENTS AND METHODS We retrospectively reviewed a total of 78 patients 39 patients underwent RAPS and 39 OSP. The following parameters were statistically evaluated and compared age, PSA value, prostate volume, ASA score, duration of hospital stay, operative time, Hb decrease on postoperative (po) day 1 and in the 5 five po days, CRP peak in the first 5 po days and transfusion rate. RESULTS The comparison between RASP and standard OSP showed no significant differences regarding the mean patient age (73 vs. 74 years; p =0.54), PSA values (7.7 vs. 10.7 ng/ml; p =0.17), ASA score (2.2 vs. 2.3; p =0.26) and prostate volume (130 vs. 113 cm3; p =0.07). Patients in the RAPAE group had statistically significant longer surgery (178 vs. 110 min; p = less then 0.01) with a significantly smaller decrease in Hb on po day 1 (1.9 vs. 3.3 g/dl; p ≤0.01) and in the first 5 po days (2.4 vs. 4.2 g/dl; p ≤0.01), lower need for preserved blood (3% vs. 26%; p =0.01) and number of blood bags (0.1 vs. 1.3; p =0.01), a lower po Clavien-Dindo score (0.44 vs. 1.23; p =0.003) and lower CRP values (52 vs. 104 mg/l; p ≤0.01) in the first 5 po days. CONCLUSION RASP is a safe procedure that offers the advantage of reduced blood loss and blood bag consumption and rare complications due to the minimally invasive surgical method. The OSP group showed an increased occurrence of complications due to bleeding, leading to prolonged hospitalization and significantly increased need for blood transfusion. The lesser increase of CRP in RASP group is a result of the lower invasiveness of the robot-assisted procedure.
