Abstract
Ectopic ACTH syndrome is a rare differential diagnosis of hypokalemic hypertension. Patients with ectopic ACTH syndrome due to small cell lung cancer have a poor prognosis. We report on a 68-year-old female patient who presented with dyspnea and hypokalemic hypertension. Endocrine testing was consistent with ectopic ACTH syndrome due to small cell lung cancer. After initiation of chemotherapy with etoposide and carboplatin ACTH and cortisol levels normalized and clinical symptoms impressively improved.

Abstract
BACKGROUND Graft-versus-host disease (GVHD) is still a major cause of morbidity and mortality after allogeneic stem cell transplantation. GVHD mainly affects skin, liver, and intestine, whereas other organs usually are spared. In the present study, we wanted to investigate whether local regulatory T cells (Treg) or differential expression of immunomodulatory molecules contribute to organ specificity of GVHD. METHODS In a murine B10.D2->BALB/c (both H-2) model, GVHD was induced by transplantation of 1x10 bone marrow and 1x10 spleen cells. We compared expression of T-cell and dendritic cell markers, CD40-CD40L, various B7 family members, FoxP3, and Th1/Th2 cytokines between ileum (GVHD-target organ) and heart (nontarget organ). RESULTS GVHD was documented by an increase of CD4 T cells with accompanying tissue destruction in ileum but not in heart. We found a significantly increased expression of PD-L1 in heart on day 14 and 21 as well as of CTLA-4 on day 21 after transplantation, whereas all other molecules were not different between heart and ileum. In heart, PD-L1 was expressed on lymphoid cells, endothelial cells, CD8alpha+CD11c+DCs, and up-regulated during GVHD. In contrast, in the ileum only endothelial cells stained weekly positive for PD-L1. Furthermore, we could not find any evidence for the presence of Tregs in the heart. CONCLUSIONS Our data indicate that immunomodulatory molecules such as PD-L1 rather than Tregs play pivotal roles in the tissue-specific regulation of alloresponses. Further studies are needed to refine the significance of the PD-L1 pathway in GVHD and its versatility for therapeutic intervention.

Abstract
BACKGROUND Humoral hypercalcaemia is a common complication of malignancy with parathyroid hormone-related protein (PTHrP) as a major cause. Breast and lung cancer are relatively common sources of ectopic PTHrP secretion leading to increased osteoclastic bone resorption. CASE REPORT We report the rare case of a 40-year-old man with severe hypercalcaemia due to a PTHrP-secreting poorly differentiated endocrine carcinoma of the pancreas. On immunohistochemistry, the tumour was positive for PTHrP and somatostatin receptors sst1, sst2, and sst3, whereas sst4 and sst5 were not detected. We demonstrate the transient improvement of hypercalcaemia after adding octreotide to the treatment mainstays in hypercalcaemia of malignancy (fluid repletion, administration of bisphosphonates, loop diuretics, and glucocorticoids). CONCLUSION To the best of our knowledge, this is the first report showing somatostatin receptor expression in a PTHrP-secreting pancreatic neuroendocrine tumour.

Abstract
Acute lung injury (ALI), such as that which occurs with mechanical ventilation, contributes to morbidity and mortality of critical illness. Nonetheless, in many instances, ALI resolves spontaneously through unknown mechanisms. Therefore, we hypothesized the presence of innate adaptive pathways to protect the lungs during mechanical ventilation. In this study, we used ventilator-induced lung injury as a model to identify endogenous mechanisms of lung protection. Initial in vitro studies revealed that supernatants from stretch-induced injury contained a stable factor which diminished endothelial leakage. This factor was subsequently identified as adenosine. Additional studies in vivo revealed prominent increases in pulmonary adenosine levels with mechanical ventilation. Because ectoapyrase (CD39) and ecto-5'-nucleotidase (CD73) are rate limiting for extracellular adenosine generation, we examined their contribution to ALI. In fact, both pulmonary CD39 and CD73 are induced by mechanical ventilation. Moreover, we observed pressure- and time-dependent increases in pulmonary edema and inflammation in ventilated cd39(-/-) mice. Similarly, pharmacological inhibition or targeted gene deletion of cd73 was associated with increased symptom severity of ventilator-induced ALI. Reconstitution of cd39(-/-) or cd73(-/-) mice with soluble apyrase or 5'-nucleotidase, respectively, reversed such increases. In addition, ALI was significantly attenuated and survival improved after i.p. treatment of wild-type mice with soluble apyrase or 5'-nucleotidase. Taken together, these data reveal a previously unrecognized role for CD39 and CD73 in lung protection and suggest treatment with their soluble compounds as a therapeutic strategy for noninfectious ALI.

Abstract
We present a case of unusual distribution of red marrow in a patient with extramedullary acute myelogenous leukemia (AML). In adults, hematopoietic marrow is usually located in the axial skeleton and the proximal aspects of the limbs, except for the epiphyses. Nodular islets of red marrow located in the epiphyseal and distal parts of the limbs may mimic tumoral infiltration and be mistaken for chloroma in a patient with AML.

Abstract
A 54-year-old woman with voiding difficulties was referred to our department. She complained about a slow urine stream, hesitancy, straining when voiding and the feeling of incomplete emptying. The gynaecological examination revealed a 4x3 cm pelvic tumour. The tumour was well circumscribed in the retropubic space between the symphysis and the bladder neck sonographically and by magnetic resonance imaging and was closed off from neighbouring structures. After removal of the tumour, the voiding problems were reversed, and the patient has remained asymptomatic. The histological examination showed a leiomyoma with high vascularisation. This case report showed that retropubic tumours can obstruct the urethra and cause voiding dysfunctions. Consequently, this needs to be considered in the differential diagnosis.

Abstract
BACKGROUND Small cell lung carcinoma (SCLC) is frequently associated with a paraneoplastic syndrome. CASE REPORT We report on a rare case of SCLC presenting with syndrome of inappropriate antidiuretic hormone (SIADH) secretion and ectopic ACTH production. In accordance with the endocrine evaluation, immunohistochemical staining of the tumour was positive for ADH and ACTH. Chemotherapy with etoposide and carboplatin induced a nearly complete remission. CONCLUSION Simultaneous secretion of ADH and ACTH is infrequently reported with only five cases described in the literature. SIADH in patients with ectopic ACTH syndrome may be underdiagnosed due to the antagonistic hormone actions of cortisol and ADH on renal sodium excretion.

Abstract
Primary extradural ependymomas are rare neoplasms usually of the myxopapillary type. Reports on malignant primary extradural ependymal tumors are exceptionally rare. We here report on a 3-year-old boy with Schinzel-Giedion syndrome (SGS), who presented with lumbar spina bifida occulta and a progressive extraspinal lesion in the subcutaneous sacrococcygeal region. Microscopic examinations revealed an uncommon ependymal tumor with well-differentiated regions reflecting myxopapillary ependymoma and highly anaplastic regions with numerous mitoses, necroses, ependymal rosettes and ependymoblastic rosettes. Final neuropathologic diagnosis was an extraspinal anaplastic ependymal tumor with myxopapillary and ependymoblastic differentiation, corresponding to WHO grade IV. SGS is a very rare disorder with a likely autosomal recessive pattern of inheritance. So far, 42 cases have been reported, among them 7 were diagnosed to have malignant neoplasms, including three malignant sacrococcygeal teratomas, two sacrococcygeal primitive neuroectodermal tumors (PNET), one hepatoblastoma and one malignant kidney tumor. The present case is the first report on an ependymal tumor with a mixture of myxopapillary, anaplastic and ependymoblastic features and the first report on an ependymal tumor arising on the genetic background of SGS.

Abstract
Acute renal failure from ischemia significantly contributes to cardiovascular morbidity and mortality. Extracellular adenosine has been implicated as an anti-inflammatory metabolite particularly during conditions of limited oxygen availability (e.g., ischemia). Because ecto-5'-nucleotidase (CD73) is rate limiting for extracellular adenosine generation, this study examined the contribution of CD73-dependent adenosine production to ischemic preconditioning (IP) of the kidneys. After the initial observation that murine CD73 transcript, protein, and function are induced by renal IP, its role in IP-mediated kidney protection was studied. In fact, increases in renal adenosine concentration with IP are attenuated in cd73(-/-) mice. Moreover, pharmacologic inhibition of CD73 or its targeted gene deletion abolished renal protection by IP as measured by clearance studies, plasma electrolytes, and renal tubular destruction, and reconstitution of cd73(-/-) mice with soluble 5'-nucleotidase resulted in complete restoration of renal protection by IP. Finally, renal injury after ischemia was attenuated by intraperitoneal treatment of wild-type mice with soluble 5'-nucleotidase to a similar degree as by IP. Taken together, these data reveal what is believed to be a previously unrecognized role of CD73 in renal protection from ischemia and suggest treatment with soluble 5'-nucleotidase as a novel therapeutic approach in the treatment of renal diseases that are precipitated by limited oxygen availability.

Abstract
BACKGROUND Innovative epigenetic therapeutics comprise histone deacetylase inhibitors (HDAC-I) and demethylating agents (DA). It was recently found that HDAC-I compounds exhibit profound therapeutic activities against hepatocellular carcinoma (HCC). A comprehensive preclinical investigation was performed on the potential of a combined HDAC-I/DA epigenetic regimen for the highly chemotherapy-resistant HCC entity. METHODS Human HCC-derived cell lines or primary human hepatocytes (PHH) were treated with HDAC-I compound suberoylanilide hydroxamic acid (SAHA) or DA compound 5-aza-2'-deoxycytidine (5-aza-dC) or both and examined for cellular damage, proliferation, histone acetylation pattern, and DNA methylation. In vivo activities were investigated in a xenograft hepatoma model. RESULTS Monotherapeutic application of SAHA or 5-aza-dC was found to induce substantial antiproliferative effects in HCC-derived cells, strongly enhanced by combined SAHA and 5-aza-dC treatment. PHH from different human donors did not exhibit any relevant cellular damage even when applying high doses of the combination regimen, whereas HCC-derived cell lines showed a dose-dependent damage. In vivo testing demonstrated a statistical significant inhibition of hepatoma cell growth for the combined treatment regime. CONCLUSIONS Because the combined HDAC-I/DA epigenetic approach was found to produce significant antitumor effects in HCC model systems and did not impair cellular integrity of untransformed hepatocytes, this combination therapy is now considered for further investigation in clinical trials.

Abstract
OBJECTIVE The purpose of our study was to assess the correlation between early high-resolution CT findings of cytomegalovirus (CMV) pneumonia in patients with blood disorders and their clinical outcomes. CONCLUSION The initial high-resolution CT findings in immunocompromised patients with CMV pneumonia seem to predict the patient's outcome being unfavorable in those forms of disease beginning mostly bilaterally as diffuse or patchy ground-glass opacity followed by progressive air-space consolidation. Also, a change in the CT morphology of pulmonary lesions toward diffuse ground-glass opacity seems to correlate with an unfavorable disease course.

Abstract
Pneumonitis is a dose-limiting side effect of radiotherapy. However, the underlying mechanisms of irradiation-induced pneumonitis are unclear. Several observations suggest that the CD95/CD95-ligand (CD95L) system is involved in this process. Therefore, we examined the development of pneumonitis in CD95- and CD95L-deficient and wild-type mice after single irradiation with 0 or 12.5 Gy by measuring breathing frequency, pulmonary resistance, and histopathologic changes. Although wild-type mice developed pathognomonic alterations characteristic of pneumonitis (judged by alveolar wall thickness, interstitial edema, and interstitial and peribronchial inflammation) that paralleled increased breathing frequency ratio on days 5-70 (P < .03) with a maximum at day 37 (12.5 Gy, mean ratio = 1.05, 95% confidence interval [CI] = 1.01 to 1.08; P = .004 versus 0 Gy, mean ratio = 0.997, 95% CI = 0.976 to 1.02; P = .05) and pulmonary resistance (day 42, 12.5 Gy, mean = 0.51, 95% CI = 0.44 to 0.58 versus 0 Gy, mean = 0.40, 95% CI = 0.32 to 0.47; P = .03) after irradiation, no such changes were detected in CD95- or CD95L-deficient mice. This report demonstrates for the first time, to our knowledge, that the CD95/CD95L system is important for the development of irradiation-induced pneumonitis.
