Pulmonary fibrosis associated with psychotropic drug therapy: a case report
Authors: Thornton Clare , Maher Toby M , Hansell David , Nicholson Andrew G , Wells Athol U 
Published: November 2009

Abstract

Introduction
Sertraline and Risperidone are commonly used psychotropic drugs. Sertraline has previously been associated with eosinopilic pneumonia. Neither drug is recognised as a cause of diffuse fibrotic lung disease. Our report represents the first such case.

Case Presentation
We describe the case of a 33 year old Asian male with chronic schizophrenia who had been treated for three years with sertraline and risperidone. He presented to hospital in respiratory failure following a six month history of progressive breathlessness. High resolution CT scan demonstrated diffuse pulmonary fibrosis admixed with patchy areas of consolidation. Because the aetiology of this man's diffuse parenchymal lung disease remained unclear a surgical lung biopsy was undertaken. Histological assessment disclosed widespread fibrosis with marked eosinophillic infiltration and associated organising pneumonia - features all highly suggestive of drug induced lung disease. Following withdrawal of both sertraline and risperidone and initiation of corticosteroid therapy the patient's respiratory failure resolved and three years later he remains well albeit limited by breathlessness on heavy exertion.

Conclusion
Drug induced lung disease can be rapidly progressive and if drug exposure continues may result in respiratory failure and death. Prompt recognition is critical as drug withdrawal may result in marked resolution of disease. This case highlights sertraline and risperidone as drugs that may, in susceptible individuals, cause diffuse pulmonary fibrosis.
Epidural lipomatosis and congenital small spinal canal in spinal anaesthesia: a case report and review of the literature
Authors: Flisberg Per , Thomas Owain , Geijer Bo , Schött Ulf 
Published: November 2009

Abstract

Introduction
Complications after lumbar anaesthesia and epidural blood patch have been described in patients with congenital small spinal canal and increased epidural fat or epidural lipomatosis. These conditions, whether occurring separately or in combination, require magnetic resonance imaging for diagnosis and grading, but their clinical significance is still unclear.

Case presentation
A 35-year-old Caucasian woman who was undergoing a Caesarean section developed a longstanding L4-L5 unilateral neuropathy after the administration of spinal anaesthesia. There were several attempts to correctly position the needle, one of which resulted in paraesthesia. A magnetic resonance image revealed that the patient's bony spinal canal was congenitally small and had excess epidural fat. The cross-sectional area of the dural sac was then reduced, which left practically no free cerebrospinal fluid space.

Conclusion
The combination of epidural lipomatosis of varying degrees and congenital small spinal canal has not been previously discussed with spinal anaesthesia. Due to the low cerebrospinal fluid content of the small dural sac, the cauda equina becomes a firm system with a very limited possibility for the nerve roots to move away from the puncture needle when it is inserted into the dural sac. This constitutes risks of technical difficulties and neuropathies with spinal anaesthesia.

AbstractBackgroundDiagnostic ultrasound provides a method of analysing soft tissue structures of the musculoskeletal system effectively and reliably. The aim of this study was to evaluate within and between session reliability of measuring muscle dorso‐plantar thickness, medio‐lateral length and cross‐sectional area, of the abductor hallucis muscle using two different ultrasound machines, a higher end Philips HD11 Ultrasound machine and clinically orientated Chison 8300 Deluxe Digital Portable Ultrasound System.MethodsThe abductor hallucis muscle of both the left and right feet of thirty asymptomatic participants was imaged and then measured using both ultrasound machines. Interclass correlation coefficients (ICC) with 95% confidence intervals (CI) were used to calculate both within and between session intra‐tester reliability. Standard error of the measurement (SEM) calculations were undertaken to assess difference between the actual measured score across trials and the smallest real difference (SRD) was calculated from the SEM to indicate the degree of change that would exceed the expected trial to trial variability.ResultsThe ICCs, SEM and SRD for dorso‐plantar thickness and medial‐lateral length were shown to have excellent to high within and between‐session reliability for both ultrasound machines. The between‐session reliability indices for cross‐sectional area were acceptable for both ultrasound machines.ConclusionThe results of the current study suggest that regardless of the type ultrasound machine, intra‐tester reliability for the measurement the abductor hallucis muscle parameters is very high.

Abstract
Introduction
Little is known about endogenous or cytokine-stimulated aggrecan catabolism in the meniscal fibrocartilage of the knee. The objectives of this study were to characterize the structure, distribution, and processing of aggrecan in menisci from immature bovines, and to identify mechanisms of extracellular matrix degradation that lead to changes in the mechanical properties of meniscal fibrocartilage.

Methods
Aggrecanase activity in the native immature bovine meniscus was examined by immunolocalization of the aggrecan NITEGE neoepitope. To investigate mechanisms of cytokine-induced aggrecan catabolism in this tissue, explants were treated with interleukin-1α (IL-1) in the absence or presence of selective or broad spectrum metalloproteinase inhibitors. The sulfated glycosaminoglycan (sGAG) and collagen contents of explants and culture media were quantified by biochemical methods, and aggrecan catabolism was examined by Western analysis of aggrecan fragments. The mechanical properties of explants were determined by dynamic compression and shear tests.

Results
The aggrecanase-generated NITEGE neoepitope was preferentially localized in the middle and outer regions of freshly isolated immature bovine menisci, where sGAG density was lowest and blood vessels were present. In vitro treatment of explants with IL-1 triggered the accumulation of NITEGE in the inner and middle regions. Middle region explants stimulated with IL-1 exhibited substantial decreases in sGAG content, collagen content, and mechanical properties. A broad spectrum metalloproteinase inhibitor significantly reduced sGAG loss, abrogated collagen degradation, and preserved tissue mechanical properties. In contrast, an inhibitor selective for ADAMTS-4 and ADAMTS-5 was least effective at blocking IL-1-induced matrix catabolism and loss of mechanical properties.

Conclusions
Aggrecanase-mediated aggrecanolysis, typical of degenerative articular cartilage, may play a physiologic role in the development of the immature bovine meniscus. IL-1-induced release of sGAG and loss of mechanical properties can be ascribed primarily to the activity of MMPs or aggrecanases other than ADAMTS-4 and ADAMTS-5. These results may have implications for the clinical management of osteoarthritis.

Abstract
Introduction
The detection of peripheral blood circulating tumor cells (CTCs) and bone marrow disseminated tumor cells (DTCs) in breast cancer patients is associated with a high incidence of disease relapse and disease-related death. Since hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) play an important role in angiogenesis and tumor progression, the purpose of the current study was to investigate their expression in CTCs.

Methods
The expression of cytokeratins (CK), VEGF, vascular endothelial growth factor receptor-2 (VEGF2), HIF-1α and phosphorylated-focal adhesion kinase (pFAK) in CTCs from 34 patients with metastatic breast cancer who had detectable CK-19 mRNA-positive CTCs was assessed using double staining experiments and confocal laser scanning microscopy. Peripheral blood mononuclear cells (PBMCs) were stained with a monoclonal A45-B/B3 pancytokeratin antibody in combination with either VEGF or VEGFR2 or HIF-1α or pFAK antibodies, respectively.

Results
pFAK expression in circulating tumor cells was detected in 92% of patients whereas expression of VEGF, VEGF2 and HIF-1α was observed in 62%, 47% and 76% of patients, respectively. VEGF, VEGF2, HIF-1α and pFAK were expressed in 73%, 71%, 56% and 81%, respectively, of all the detected CTCs. Vascular endothelial growth mRNA was also detected by quantitative real-time RT-PCR in immunomagnetically-separated CTCs. Double and triple staining experiments in cytospins of immunomagnetically-isolated CTCs showed that VEGF co-expressed with HIF-1α and VEGF2.

Conclusions
The expression of pFAK, HIF-1α, VEGF and VEGF2 in CTCs of patients with metastatic breast cancer could explain the metastatic potential of these cells and may provide a therapeutic target for their elimination.

AbstractIntroductionResults from clinical studies have provided evidence for the importance of leukocyte-endothelial interactions in the pathogenesis of pulmonary diseases such as acute lung injury (ALI) and acute respiratory distress syndrome (ARDS), as well as in systemic events like sepsis and multiple organ failure (MOF). The present study was designed to investigate whether alveolar stretch due to mechanical ventilation (MV) may evoke endothelial activation and inflammation in healthy mice, not only in the lung but also in organs distal to the lung.MethodsHealthy male C3H/HeN mice were anesthetized, tracheotomized and mechanically ventilated for either 1, 2 or 4 hours. To study the effects of alveolar stretchin vivo, we applied a MV strategy that causes overstretch of pulmonary tissue i.e. 20 cmH2O peak inspiratory pressure (PIP) and 0 cmH20 positive end expiratory pressure (PEEP). Non-ventilated, sham-operated animals served as a reference group (non-ventilated controls, NVC).ResultsAlveolar stretch imposed by MV did not only inducede novosynthesis of adhesion molecules in the lung but also in organs distal to the lung, like liver and kidney. No activation was observed in the brain. In addition, we demonstrated elevated cytokine and chemokine expression in pulmonary, hepatic and renal tissue after MV which was accompanied by enhanced recruitment of granulocytes to these organs.ConclusionsOur data implicate that MV causes endothelial activation and inflammation in mice without pre-existing pulmonary injury, both in the lung and distal organs.

Abstract
Introduction
Severe thermal injury is characterized by profound morbidity and mortality. Advances in burn and critical care, including early excision and grafting, aggressive resuscitation and advances in antimicrobial therapy have made substantial contributions to decrease morbidity and mortality. Despite these advances, death still occurs. Our aim was to determine the predominant causes of death in burned pediatric patients in order to develop new treatment avenues and future trajectories associated with increased survival.

Methods
Primary causes of death were reviewed from 144 pediatric autopsy reports. Percentages of patients that died from anoxic brain injuries, sepsis, or multi-organ failure were calculated by comparing to the total number of deaths. Data was stratified by time (from 1989 to 1999, and 1999 to 2009), and gender. Statistical analysis was done by chi-squared, Student's t-test and Kaplan-Meier for survival where applicable. Significance was accepted as P < 0.05.

Results
Five-thousand two-hundred-sixty patients were admitted after burn injury from July 1989 to June 2009, and of those, 145 patients died after burn injury. Of these patients, 144 patients had an autopsy. The leading causes of death over 20 years were sepsis (47%), respiratory failure (29%), anoxic brain injury (16%), and shock (8%). From 1989 to 1999, sepsis accounted for 35% of deaths but increased to 54% from 1999 to 2009, with a significant increase in the proportion due to antibiotic resistant organisms (P < 0.05).

Conclusions
Sepsis is the leading cause of death after burn injury. Multiple antibiotic resistant bacteria now account for the bulk of deaths due to sepsis. Further improvement in survival may require improved strategies to deal with this problem.

AbstractOnline gene annotation resources are indispensable for analysis of genomics data. However, the landscape of these online resources is highly fragmented, and scientists often visit dozens of these sites for each gene in a candidate gene list. Here, we introduce BioGPS http://biogps.gnf.org, a centralized gene portal for aggregating distributed gene annotation resources. Moreover, BioGPS embraces the principle of community intelligence, enabling any user to easily and directly contribute to the BioGPS platform.

PurposeBiochemotherapy improves responses in metastatic melanoma, but not overall survival, in randomized trials. We developed a maintenance biotherapy regimen after induction biochemotherapy in an attempt to improve durability of responses and overall survival.Patients and MethodsOne hundred thirty-three chemotherapy-naïve patients with metastatic melanoma without CNS metastases were treated at 10 melanoma centers. The biochemotherapy induction regimen included cisplatin, vinblastine, dacarbazine, decrescendo interleukin-2 (IL-2), and interferon alfa-2b with granulocyte-macrophage colony-stimulating factor (GM-CSF) cytokine support. Patients not experiencing disease progression were eligible for maintenance biotherapy with low-dose IL-2 and GM-CSF followed by intermittent pulses of decrescendo IL-2 over 12 months. Patients were observed for response, progression-free survival, toxicity, and overall survival.ResultsThe response rate to induction biochemotherapy was 44% (95% CI, 35% to 52%; complete response, 8%; partial response, 36%; stable disease, 29%). The median number of biochemotherapy cycles was four, and the median number of maintenance biotherapy cycles was five. The median progression-free survival was 9 months, and the median survival was 13.5 months. The 12-month and 24-month survival rates were 57% and 23%, respectively. Twenty percent of patients remain alive (12 without disease), with median follow-up of 30 months (95% CI, 25+ to 45+ months). Thirty-nine percent of patients developed CNS metastases. The median times to CNS progression and death were 8 months and 5 months, respectively.ConclusionMaintenance biotherapy after induction biochemotherapy seems to prolong progression-free survival and improve overall survival compared with recent multicenter trials of biochemotherapy or chemotherapy. The regimen should be studied in a randomized clinical trial in patients with advanced metastatic melanoma. CNS progression remains a formidable challenge.

Purpose We investigated the global gene expression in a large panel of pancreatic endocrine tumors (PETs) aimed at identifying new potential targets for therapy and biomarkers to predict patient outcome. Patients and Methods Using a custom microarray, we analyzed 72 primary PETs, seven matched metastases, and 10 normal pancreatic samples. Relevant differentially expressed genes were validated by either quantitative real-time polymerase chain reaction or immunohistochemistry on tissue microarrays. Results Our data showed that: tuberous sclerosis 2 (TSC2) and phosphatase and tensin homolog (PTEN) were downregulated in most of the primary tumors, and their low expression was significantly associated with shorter disease-free and overall survival; somatostatin receptor 2 (SSTR2) was absent or very low in insulinomas compared with nonfunctioning tumors; and expression of fibroblast growth factor 13 (FGF13) gene was significantly associated with the occurrence of liver metastasis and shorter disease-free survival. TSC2 and PTEN are two key inhibitors of the Akt/mammalian target of rapamycin (mTOR) pathway and the specific inhibition of mTOR with rapamycin or RAD001 inhibited cell proliferation of PET cell lines. Conclusion Our results strongly support a role for PI3K/Akt/mTOR pathway in PET, which ties in with the fact that mTOR inhibitors have reached phase III trials in neuroendocrine tumors. The finding of differential SSTR expression raises the potential for SSTR expression to be evaluated as a marker of response to somatostatin analogs. Finally, we identified FGF13 as a new prognostic marker that predicted poorer outcome in patients who were clinically considered free from disease.

Purpose To retrospectively analyze the clinical features and results of treatment in 56 infants with fibrosarcoma enrolled onto cooperative European protocols between 1979 and 2005 and treated with a combination of surgery and chemotherapy. Patients and Methods We performed a retrospective case review of infants under the age of 2 years with fibrosarcoma treated between 1979 and 2005 in six European studies. Patients were staged according to the Intergroup Rhabdomyosarcoma Staging System international classification as a function of the type of initial surgery and the extent of disease and were treated with surgery and chemotherapy. Survival was calculated using the Kaplan-Meier method. Results Primary tumor site was the limbs in 66% of patients; median tumor diameter was more than 5 cm in 63% of patients; and postoperative staging was as follows: group I, 22%; group II, 27%; group III, 47%; and group IV, 4%. Response rate to chemotherapy was 75%, and the specific response rate to vincristine-dactinomycin was 71%. Local control was obtained in 84% of patients. At the end of follow-up, 45% of survivors had been treated by surgery alone, 6% by chemotherapy alone, 46% by surgery and chemotherapy, and 2% by surgery, chemotherapy, and radiotherapy. The 5-year overall survival (OS) rate was 89%. The 5-year OS and event-free survival rates for localized patients were 89% and 81%, respectively. Conclusion Although complete resection is rarely feasible at diagnosis, conservative surgery remains the mainstay treatment for infantile fibrosarcoma. An alkylating agent–free and anthracycline-free regimen is usually effective and should be chosen as first-line chemotherapy for inoperable tumors. Overall prognosis is good, but progression or relapse, mainly local, remains possible.

Published: November 2009

Purpose Patients with cancer experience considerable symptom burden, psychological morbidity, and unmet psychosocial needs. Research suggests that feedback of patient-reported outcomes to clinicians or caseworkers, alongside management strategies, may result in improved patient functioning. Two intervention models were developed to test this effect in a randomized, controlled trial against usual care (UC): a telephone caseworker (TCW) model and an oncologist/general practitioner (O/GP) model. Primary end points included anxiety, depression, physical/emotional functioning, and unmet supportive care needs. Patients and Methods Participants with nonlocalized breast or colorectal cancers were surveyed by computer-assisted telephone interview (CATI) at three time points: baseline, 3 months, and 6 months. Data collected from participant CATIs in the supportive care models were used to generate feedback to either each participant's designated TCW, or their nominated O/GPs. Data obtained from participants in the UC model were used only to assess the impact of supportive care models. In total, 356 participants consented to study participation, completed the baseline CATI, and were randomly assigned to the UC, TCW, or O/GP groups. Results No overall intervention effect was observed. Physical functioning was significantly improved at the third CATI for participants in the TCW model (P = .01), and there was a trend toward fewer participants with unmet needs (P = .07). TCW group participants also were more likely to have the following: identified issues of need discussed (P < .0001); referrals made (P < .0001); and strong agreement that the intervention improved communication with their health care team (P = .0005). Conclusion The TCW model holds some promise; however, additional work in at-risk populations is required before we recommend implementation.
