Light-chain deposition disease (LCDD) is a rare plasma cell neoplasm that secretes an abnormal immunoglobulin light chain, which is deposited in tissues, leading to organ dysfunction. Spontaneous splenic rupture is a rare and life-threatening complication of treatment with granulocyte colony-stimulating factor (G-CSF). Herein, we describe spontaneous splenic rupture after the administration of lenograstim to a patient with LCDD undergoing autologous stem cell transplantation (ASCT). The patient was successfully treated by transcatheter embolization of the splenic artery, and long-term stringent complete remission was attained. Plasma cell neoplasms, including multiple myeloma with amyloidosis, are among the most commonly reported conditions associated with spontaneous splenic rupture in patients undergoing ASCT. This finding suggests that, in addition to the effect of G-CSF on the spleen, a combination of factors, including tissue vulnerability induced by the infiltration of abnormal immunoglobulins, may be involved in the pathogenesis of spontaneous splenic rupture. Notably, splenomegaly is not always evident in these patients. Surgical treatment may not be an option, because of severe myelosuppression, and thus less invasive treatment using transcatheter embolization may be feasible.

Mood stabilizers such as lithium (Li) or valproic acid (VPA) are used in the therapy of bipolar disorders, but the mechanisms by which these medicines work is unclear. Recently, neuroprotection has attracted attention as a potential action for VPA and Li. The close spatial relationship of the pre- and post-synapse with an astrocyte process within a 'tripartite synapse' suggests that mood stabilizer actions on astrocytes may be important. Therefore, we examined the effect of Li and VPA, at therapeutic concentrations, on brain-derived neurotrophic factor (BDNF) production in cultured human astrocytoma cells over an extended period of exposure. Released (extracellular) and intracellular BDNF was measured with sandwich-ELISA. Intracellular BDNF mRNA was also quantified using RT-PCR. VPA treatment potentiated the level of extracellular BDNF, whereas Li reduced it. Furthermore, VPA caused increased intracellular levels of BDNF protein and mRNA, while exposure to Li led to no significant differences compared to control cells. We suggest the possibility that VPA and Li have divergent effects on astrocyte BDNF production. Mood stabilizers play an essential role in regulating BDNF not only in neurons, but also in astrocytes. These findings could form the basis of a new astrocyte-targeted approach towards developing effective medications to treat bipolar disorders. © 2011 Elsevier Inc.

OBJECTIVE:: To clarify the prognostic value of the preoperative blood neutrophil-to-lymphocyte ratio (NLR) in patients undergoing hepatectomy for hepatocellular carcinoma (HCC). BACKGROUND:: Although a high NLR has been reported to be a predictor of poor survival in patients with various cancers, it has not been extensively examined in patients with HCC. METHODS:: This retrospective study enrolled 958 patients who underwent hepatectomy without preoperative therapy for HCC from 1996 to 2009. Clinicopathological parameters, including NLR, were evaluated to identify predictors of overall and recurrence-free survival after hepatectomy. Univariate and multivariate analyses were performed, using the Cox proportional hazards model. The best cutoff was determined with time-dependent receiver operating characteristic curve. To determine the mechanism of NLR elevation, immunohistological examination using CD163 staining was performed in 150 patients. RESULTS:: Univariate and multivariate analyses showed that NLR was an independent prognostic factor in overall and recurrence-free survival. The best cutoff of NLR was 2.81, and 238 of 958 patients (24.8%) had NLR of more than 2.81. The 5-year survival rate after hepatectomy was 72.9% in patients with NLR less than 2.81 and 51.5% in those with NLR 2.81 or more (P < 0.0001). CD163-positive cell counts were significantly higher in tumors in the group with NLR 2.81 or more than in the group with NLR less than 2.81 (P = 0.0004). CONCLUSIONS:: Our results show that NLR is an independent predictor of survival after hepatectomy in patients with HCC. Accumulation of tumor-associated macrophages in the tumor is associated with a high NLR. Copyright © 2013 Lippincott Williams & Wilkins.

We report a 70-year-old man who suffered from right anterior chest wall tumor. Physical examination revealed an elastic hard mass at the right 4th rib measured 6 cm in diameter. Chest X-ray and computed tomography (CT) revealed enhanced mass and destruction of the 4th rib. As needle aspiration cytology did not define the diagnosis, we performed a chest wall resection and reconstruction. Histological diagnosis of the tumor was plasmacytoma (IgG lambda type). Five months after the operation, the tumor recurred at the right anterior chest wall. Radiotherapy was performed with dose of 50 Gy. Fourteen months after the operation, the tumor recurred at the lower sternum, and the chemotherapy was performed using ranimustine, vincristine, melpharan and dexamethasone. He is doing well 2 years and 9 months after surgery without signs of progressive disease or conversion to myeloma

Background: Diagnosis has a major impact on the outcome of subarachnoid hemorrhage (SAH). We studied patients with SAH who were admitted to our hospital in an effort to identify ways to prevent misdiagnosis. Methods: A total of 494 patients with SAH were admitted to the Department of Neurosurgery from 2003 through 2010. Misdiagnosis occurred in 30 patients (6.1%). We studied the symptoms and the types of misdiagnoses in these 30 patients. Results: Misdiagnosis occurred 37 times in the 30 patients (6 patients were given more than 1 misdiagnosis). There were 3 types of misdiagnoses. Type 1 cases were misdiagnosed as a common cold, type 2 cases were misdiagnosed as circulatory organ disease, and type 3 cases were misdiagnosed as digestive organ disease. Conclusions: Type 1 cases were mild, and diagnosis required detailed medical history analyses. Type 2 cases were severe and were diagnosed based on electrocardiographic and echocardiographic changes characteristic of SAH. Symptoms of type 3 cases included vomiting, and diagnosis required recognition of meningeal irritation syndrome and detailed medical history analyses. © 2013 by National Stroke Association.

Erlotinib is a potent drug used for treating epidermal growth factor receptor (EGFR) mutation positive lung cancer. In this study, we report a case of erlotinib induced cutaneous vasculitis. The patient was a 69-year-old woman with a history of left lower lobe resection for lung cancer. Two years after the resection, she had metastasis in the adrenal glands for which we initiated erlotinib therapy at a dose of 150 mg/day. The patient developed multiple purpurae with a partially necrotic region on both lower thighs at 8 weeks after initiating therapy. The skin biopsy results revealed cutaneous vasculitis. We stopped erlotinib therapy after this diagnosis because of this adverse effect as well as because it exacerbated the cancer. The patient's skin manifestation disappeared 2 weeks after stopping therapy, with no recurrence of any symptoms of systemic vasculitis. We reviewed the literature on drug-induced vasculitis due to oral EGFR inhibitors and found 13 such cases. In most cases, the symptoms appeared 1-2 months after initiating therapy. In all the cases, the symptoms resolved within 2-6 weeks after stopping drug therapy. Erlotinib-induced cutaneous vasculitis is rare but may cause fatal systemic vasculitis. Therefore, the skin of patients who are undergoing erlotinib therapy should be carefully examined at regular intervals during the course of therapy for drug-induced adverse effects.

Focal segmental glomerulosclerosis (FSGS) is a podocyte disease. Among the various histologies of FSGS, active epithelial changes, hyperplasia, as typically seen in the collapsing variant, indicates disease progression. Using a podocyte specific injury model of FSGS carrying a genetic podocyte tag combined with double immunostaining by different sets of podocytes and parietal epithelial cell (PEC) markers [nestin/Pax8, Wilms' tumor-1 (WT1)/claudin1, and podocalyxin/Pax2], we investigated the direction of epithelial phenotypic transition and its role in FSGS. FSGS mice showed progressive proteinuria and renal dysfunction often accompanied by epithelial hyperplasia, wherein 5-bromo-4-chloro-3-indoyl β-D-galactoside (X-gal)-positive podocyte-tagged cells were markedly decreased. The average numbers of double positive cells in all sets of markers were significantly increased in the FSGS mice compared with the controls. In addition, the average numbers of double-positive cells for X-gal/Pax8, nestin/Pax8 and podocalyxin/Pax2 staining in the FSGS mice were comparable, whereas those of WT1/claudin1 were significantly increased. When we divided glomeruli from FSGS mice into those with FSGS lesions and those without, double-positive cells tended to be more closely associated with glomeruli without FSGS lesions compared with those with FSGS lesions. Moreover, the majority of double-positive cells appeared to be isolated and very rarely associated with FSGS lesions (1/1,997 glomeruli). This study is the first to show the incidence and localization of epithelial cells with phenotypical changes in FSGS using a genetic tag. The results suggest that the major direction of epithelial phenotypic transition in cellular FSGS is from podocytes to PECs and that these cells were less represented in the active lesions of FSGS. © 2014 the American Physiological Society.

Purpose: Combined pulmonary fibrosis and emphysema (CPFE) is increasingly recognized, as current reports of its clinical features show. To determine CPFE's physiologic and radiologic features, we conducted quantitative assessment of computed tomography scans to compare with those of chronic obstructive pulmonary disease (COPD). Methods: In 23 patients with CPFE and 42 patients with COPD, we measured the extent of emphysema (LAA %), parenchymal density, and total cross-sectional areas of pulmonary vessels smaller than 5 mm2 (%CSA <5) and 5-10 mm2 (%CSA 5-10). Results: For CPFE, airflow was better, but diffusing capacity for carbon monoxide (DLCO) was worse than for COPD, whereas LAA % was similar for both groups. The %CSA <5 was greater but %CSA5-10 was less in CPFE than COPD. COPD involved a negative correlation between DLCO and LAA % at all lung sites; those factors correlated for CPFE only in the upper lobe (r = -0.535). In contrast, CPFE had a negative correlation between DLCO and parenchymal density in lower lobes (r = -0.453), but COPD showed no correlation in any such sections. In CPFE, no correlation was apparent between LAA in upper lobes and parenchymal density in lower lobes. The annual rate of FVC decline (-169.26 ml/year) in CPFE patients correlated with parenchymal density (r = -0.714). Conclusions: In CPFE, fibrosis and emphysema apparently existed independently, but both correlate with and likely contribute to the disproportionate reduction in gas exchange. Our study also suggested that pulmonary fibrotic changes may be more important contributors than emphysema for disease progression. © 2013 Springer Science+Business Media New York.

Revisions to the Organ Transplant Act have made it possible for the organs of a brain-dead patient to be donated for transplantation with the permission of the patient's family only, even if the patient's desires regarding donation have not been set out in writing, in all brain-death cases unless the patient has expressly indicated that they do not wish to be an organ donor. However, there has fundamentally been no change in the "legal determination of brain death"; the main changes to the Act are those related to the broadening of the age range for organ donor eligibility. Under these revisions, age divisions have also been set at ages 6 and 18 as well as the original 15, and the criteria and conditions for organ donor eligibility in each age group have become more complicated. Under the original Act, in cases where there is damage to a patient's eardrum, vestibular reflex was deemed to be impossible to perform and a legal determination of brain death was not made. However, under these revisions, regardless of the patient's age, it is now possible to perform tests to ascertain brain death using sterile physiological saline. In fact, from a medical standpoint the legal determination of brain death has a limited range of discretion, and since some matters such as the order in which tests are performed may be trivial medically, they may hold significant meaning legally and is required utmost care.

Fibrin glues are widely used for various pulmonary operations, but commercially produced glues are made of heterogeneous fibrinogen that has infection risks. We used autologous cryoprecipitate and evaluated its clinical value as a fibrin sealant instead of the commercially available glue. One hundred patients who underwent thoracoscopic bullectomy for primary spontaneous pneumothorax were studied. The apical visceral pleura was covered with an absorbable mesh and a fibrin glue. Autologous cryoprecipitate glue was used in 30 patients (group A), and commercially produced fibrinogen was used in 70 (group B). The mean duration of postoperative chest drainage was 1.9 days in group A and 1.5 days in group B. The cumulative 2-year postoperative recurrence rate was 3.4% in group A and 6.5% in group B. There were no differences in clinical results after surgery for primary spontaneous pneumothorax, using either autologous cryoprecipitate or commercially produced fibrinogen. The production autologous cryoprecipitate was easy and low-cost. We propose that autologous cryoprecipitates be used in operations for primary spontaneous pneumothorax. © SAGE Publications 2009.
