A case of Budd-Chiari syndrome in which direct surgical intervention was successfully performed is reported. A 43-year-old female who had had a history of hepatic coma was pointed out complete obstruction of inferior vena cava (IVC) between the right atrium and diaphragma, associated with hepatic dysfunction and esophageal varices. At operation, the IVC lesion was visualized directly by thoracotomy through midsternal incision and by laparotomy through right hypochondrial oblique incision, with the liver retracted. Under partial extracorporeal circulation with suction of blood from hepatic vein, the IVC was incised, 3cm in length, and membranous tissue causing obstruction was resected. The defect of the IVC wall was repaired with ringed EPTFE patch. Postoperatively, both central venous and portal pressure were decreased, 21 mmHg to 10mmHg and 26cm H2O to 21cm H2O, respectively, with good patency of the IVC on venogram. Now the patient is up and well, 11 months after operation. Thus, complete removal of obstruction under direct vision is thought to be important for surgical treatment of Budd-Chiari syndrome.

STUDY DESIGN: Case series. PURPOSE: The aim of this study was to describe translaminar microendoscopic herniotomy (TL-MEH) for cranially migrated lumbar disc herniations encroaching on the exiting nerve root in the preforaminal and foraminal zones and to report preliminary results of the procedure. OVERVIEW OF LITERATURE: Conventional interlaminar approaches for preforaminal and foraminal lumbar disc herniations result in extensive removal of the lamina and facet joint to remove disc fragments safely. More destructive approaches increase the risk of postoperative segmental instability. METHODS: TL-MEH is a minimally invasive procedure for herniotomy via the translaminar approach using a microendoscopic technique. TL-MEH was performed in seven patients with a cranially migrated lumbar disc herniation encroaching on the exiting nerve root. The disc fragments were located in the preforaminal zone in four patients, and in the preforaminal and foraminal zones in three. RESULTS: All patients experienced immediate relief from symptoms after surgery and satisfactory results at the final follow-up. Surgical complications, such as a dural tear, nerve injury, and surgical site infection, were not investigated. CONCLUSIONS: TL-MEH seemed to be an effective and safe alternative minimally invasive surgical option for patients with a cranially migrated lumbar disc herniation encroaching the exiting nerve root in the preforaminal and foraminal zones.

Objective:
Environmental deprivation, a type of childhood maltreatment, has been reported to constrain the cognitive developmental processes such as associative learning and implicit learning, which may lead to functional and morphological changes in the ventral pallidum (VP) and pessimism, a well-known cognitive feature of major depression. We examined whether neonatal isolation (NI) could influence the incidence of learned helplessness (LH) in a rat model mimicking the pessimism, and the number of vesicular glutamate transporter 2 (VGLUT2)-expressing VP cells and Penk-expressing VP cells.
Methods:
The number of escape failures from foot-shocks in the LH test was measured to examine stress-induced depression-like behavior in rats. The number of VGLUT2-expressing VP cells and Penk-expressing VP cells was measured by immunohistochemistry.
Results:
In NI rats compared with Sham rats, the incidence of LH in adulthood was increased and VGLUT2-expressing VP cells but not Penk-expressing VP cells in adulthood were decreased. VGLUT2-expressing VP cells were decreased only in the LH group of NI rats and significantly correlated with the escape latency in the LH test.
Conclusion
These findings suggest that the aberrant VP neuronal activity due to environmental deprivation early in life leads to pessimistic associative and implicit learning. Modulating VP neuronal activity could be a novel therapeutic and preventive strategy for the patients with this specific pathophysiology.

Objective: We investigated the association between catastrophizing with regard to numbness and pain, subjective symptoms, upper extremity function, and disability in cancer patients with chemotherapy-induced peripheral neuropathy (CIPN). Method: We evaluated catastrophizing (pain catastrophizing scale [PCS] total score, rumination, helplessness, magnification), subjective symptoms of numbness and pain, upper extremity function, and disability in patients with hematological malignancy and gastrointestinal cancer who developed upper extremity CIPN. We calculated the Spearman’s rank correlation coefficient to determine the strength of the association. Result: A significant association was observed between catastrophizing and disability; however, upper extremity function was not significantly association with catastrophizing. Based on the PCS subscale scores, only rumination was significantly association with subjective symptoms. Conclusion: Functional assessment and approaches may not be sufficient to improve the activities of daily living in cancer patients with upper extremity CIPN, and assessment and approaches to cognitive aspects, such as catastrophizing, should also be considered.
