Iniencephaly and long-term survival: a rare case report

Introduction Iniencephaly, a neural tube defect involving occiput and inion and combined with rachischisis of the cervical, thoracic spine, and retroflexion position of the head is a very rare congenital abnormality of the fetus–newborn with a 0.1–10 of 10,000 prevalence. This abnormality’s prognosis is thought to be dismal. This abnormality can be associated with other abnormalities such as anencephaly, encephalocele, hydrocephalus, cyclopia, absence of the mandible, cleft lip and palate, cardiovascular disorders, diaphragmatic hernia, renal abnormalities, overgrowth of the arms compared to the legs, and club food and gastrointestinal atresia. Discussion Most of the patients are dead born, and the others die in a few hours. There are only six previously documented long-term survivors. In our case, our patient with iniencephalic signs and findings is still living. She is 2 years old now. We think that this patient presents a mild form of iniencephaly.     

Cervical soft tissue imaging using a mobile CBCT scanner with a flat panel detector in comparison with corresponding CT and MRI data sets.

OBJECTIVE: The aim of this study was to evaluate soft tissue image quality of a mobile cone-beam computed tomography (CBCT) scanner with an integrated flat-panel detector. STUDY DESIGN: Eight fresh human cadavers were used in this study. For evaluation of soft tissue visualization, CBCT data sets and corresponding computed tomography (CT) and magnetic resonance imaging (MRI) data sets were acquired. Evaluation was performed with the help of 10 defined cervical anatomical structures. RESULTS: The statistical analysis of the scoring results of 3 examiners revealed the CBCT images to be of inferior quality regarding the visualization of most of the predefined structures. Visualization without a significant difference was found regarding the demarcation of the vertebral bodies and the pyramidal cartilages, the arteriosclerosis of the carotids (compared with CT), and the laryngeal skeleton (compared with MRI). Regarding arteriosclerosis of the carotids compared with MRI, CBCT proved to be superior. CONCLUSIONS: The integration of a flat-panel detector improves soft tissue visualization using a mobile CBCT scanner.     

Kniegelenkluxationen

Zusammenfassung Kniegelenkluxationen sind seltene, aber schwer wiegende Verletzungen mit z. T. erheblichen Folgen. Begleitende Nerven- und Gefäßverletzungen sind nicht selten. Bei spontaner Reposition kann das Verletzungsausmaß initial unterschätzt werden. Die primäre Diagnostik muss die neurologische Untersuchung sowie die sichere Beurteilung des Gefäßstatus einschließen. Die Sicherung der Durchblutung des betroffenen Beins steht in der Akutphase im Vordergrund, Läsionen müssen notfallmäßig operativ versorgt werden. Bei drohendem Kompartment ist eine Faszienlogenspaltung erforderlich, die Instabilität wird temporär mittels Fixateur externe transfixiert. Bei Hochrasanztraumen sind Begleitverletzungen auszuschließen, bei sedierten und beatmeten Patienten z. B. mit Spiral-CT. Sind nur die Kreuzbänder betroffen, kann ein arthroskopisch gestützter Ersatz vorgenommen werden, Transplantate werden bevorzugt von der Gegenseite entnommen. Die im angloamerikanischen Sprachraum verwendeten Allografts haben sich in unserer Region noch nicht durchgesetzt. Bei ausgedehnten Kapselläsionen und Beteiligung der Kollateralbänder sind arthroskopische Techniken nicht indiziert, es sollte offen rekonstruiert und ggf. augmentiert werden; sekundär verbliebene Instabilitäten können gezielt dem Bandersatz zugeführt werden.     

Stereological evaluation of liver volume in living donor liver transplantation using MDCT via the Cavalieri method.

In living donor liver transplantation (LDLT), obtaining the precise volume of the graft is very important to decrease volume-related postoperative complications, especially in cases with suspected small-for size grafts. We used stereology based on the Cavalieri method (CM), a new method to measure liver graft volume, and compared the results with those obtained through intraoperative measurement (IOM) and through multidetector computed tomography (MDCT) measurement. Liver volumes estimated using the 3 methods were well-correlated with each other (r(2) = 0.94 and P < 0.001 for IOM and CM; r(2) = 0.91 and P < 0.001 for IOM and MDCT, and r(2) = 0.95 and P < 0.001 for CM and MDCT); however, they were different from each other (in descending order, 908 +/- 124 cm(2), 861 +/- 121 cm(2), and 777 +/- 168 cm(2) for MDCT, CM, and IOM, respectively). Although MDCT and CM overestimated the volumes, the results of CM were almost similar to those obtained via IOM. In conclusion, our results suggest that CM measured the liver graft volume more reliably. Thus, its use, particularly in cases with suspected small-for-size graft, may prove useful.     

Das Cinderella-Schuh-Syndrom

The Cinderella shoe syndrome specifies a commonly observed, not yet labeled disproportion of footwear and the morphologic conditions of the wearer. Disproportioned shoes and socks are worn–frequently unconsciously–due to personal reasons, fashion trends, misinformation and wrong advice; they can induce severe foot disorders. The Cinderella shoe syndrome has an important significance within the development, the treatment and the recurrence-prophylaxis of foot disorders, as well as in the assessment of possible reasons for recurrence after foot surgery. To recognize it, to treat individual psychologic reasons, to give support in the choice of footwear, to inform about and to change social reasons are all challenges of the foot surgeon.
