Vallecular cyst should be included in the differential diagnosis of stridor in newborn infants. Respiratory and feeding difficulties in these patients can be dramatically improved after appropriate surgical removal of the cyst.

Poisoning caused by ingesting insecticides containing permethrin, xylene, and surfactant manifests primarily gastrointestinal tract symptoms and signs. The involvement of the central nervous system and lungs were less common, but clinically more significant. The relative contributions of the 20% permethrin, 70% xylene, and 10% surfactant to these toxic manifestations, however, is uncharacterized.

PRUV is a common vascular anomaly that is easy to be overlooked. Reconstruction of the portal system in the affected fetuses using 3D ultrasound facilitated the identification of the DV. If the DV is present, and other anomalies are excluded, the fetus with PRUV has a good outcome.

Virulent Klebasiella pneumoniae (KP) inflicts severe liver abscesses in infected patients. This study investigated how the bacterial infection affected cell survival at the molecular level, in a cultured cell model. A strain of KP highly virulent in mice was isolated from a patient with liver abscess, and was used to infect HepG2 cells. The infected cells were examined for their viability, DNA fragmentation, and proteins involved in apoptosis or necrosis. We found that the infection decreased the viability of HepG2 cells at 4 hours (h) to 12 h post infection (pi). DNA ladders appeared 6-16 h pi and flow cytometry analysis showed apoptosis at 3-5 h pi, secondary necrosis at 6-9 h pi and primary necrosis at 8-9 h pi. Cleavages of Caspase 7, Caspase 9, α-Fodrin, and PARP were evident at 2-4 h pi. At 7 h pi, we observed the following: increased nuclear AIF, the release from mitochondria of cytosolic Apaf-1 and Cyt c, increased DFF40 expression, decreased DFF45, decreased BcL-xL and the release of Endo G from mitochondria to nucleus. Cellular ATP concentration decreased at 4-8 h pi, accompanied by increased Calpain-2 expression. In summary, infected HepG2 cells underwent apoptosis early after infection and progressed to secondary necrosis and primary necrosis. Nuclear fragmentation corresponded to Caspase 7 activation and the appearance of Endo G and DFF40 in the nucleus, with a concomitant decrease in DFF45. Mitochondrial release of Cyt c together with activation of Caspase 9 and Apaf-1 in cytosol was also observed. Early-hour cleavage of poly(ATP-ribose) polymerase (PARP) followed by the later activation of PARP corresponded to the appearance of DNA laddering, and the depletion of cellular ATP was associated with the appearance of necrosis.

Treatment with tibolone attenuated the development of OA, concomitantly reduced nociception and increased serum alkaline phosphatase in ACLT + OVX rats.

Hedgehog signaling pathway might play a role during tumorigenesis of SPT, MCN, IPMN, and PA. Mucinous cystic neoplasm and PA exhibit an autocrine regulation of sHh, whereas SPT and IPMN do not. Overexpression of Ptc1 and Gli, reflected by cyclin D1, might represent proliferative potential of various pancreatic neoplasms.
