Incidence of synchronous appendiceal neoplasm in patients with colorectal cancer and its clinical significance

<p>Abstract</p> <p>Background</p> <p>The aims of this study were to evaluate the incidence of synchronous appendiceal neoplasm in patients with colorectal cancer, and to determine its clinical significance.</p> <p>Methods</p> <p>Pathological reports and medical records were reviewed of patients with colorectal adenocarcinoma who underwent oncological resection of the tumor together with appendectomy at the Faculty of Medicine Siriraj Hospital, Mahidol University, Thailand between September 2000 and April 2008.</p> <p>Results</p> <p>This study included 293 patients with an average age of 62 years (range 19–95) and 51 percent were male. Of the patients studied, 228 (78 percent) had right hemicolectomy, whereas the others (22 percent) had surgery for left-sided colon cancer or rectal cancer. One patient (0.3 percent) had epithelial appendiceal neoplasm (mucinous cystadenoma) and 3 patients (1.0 percent) had metastatic colorectal cancer in the mesoappendix. However, the presence of synchronous appendiceal tumors and/or metastasis did not alter postoperative management, as these patients had received adjuvant therapy and were scheduled for surveillance program because of nodal involvement.</p> <p>Conclusion</p> <p>The incidence of synchronous primary appendiceal neoplasm and secondary (metastatic) appendiceal neoplasm in colorectal cancer patients was 0.3 and 1.0 percent, respectively. However, these findings did not change the postoperative clinical management.</p

Diabetes mellitus is associated with increased mortality during tuberculosis treatment: a prospective cohort study among tuberculosis patients in South-Eastern Amahra Region, Ethiopia

Background There is growing evidence suggesting that diabetes mellitus (DM) affects disease presentation and treatment outcome in tuberculosis (TB) patients. This study aimed at investigating the role of DM on clinical presentations and treatment outcomes among newly diagnosed TB patients. Methods A prospective cohort study was conducted in South-Eastern Amhara Region, Ethiopia from September 2013 till March 2015. Study subjects were consecutively recruited from 44 randomly selected health facilities in the study area. Participants were categorized into two patient groups, namely, patients with TB and DM (TBDM) and TB patients without DM (TBNDM). Findings on clinical presentations and treatment outcomes were compared between the two patient groups. Cox proportional hazard regression analysis was applied to identify factors associated with death. Results Out of 1314 TB patients enrolled in the study, 109 (8.3 %) had coexisting DM. TBDM comorbidity [adjusted hazard ratio (AHR) 3.96; 95 % confidence interval (C.I.) (1.76–8.89)], and TB coinfection with human immunodeficiency virus (HIV) [AHR 2.59; 95 % C.I. (1.21–5.59)] were associated with increased death. TBDM and TBNDM patients did not show significant difference in clinical symptoms at baseline and during anti-TB treatment period. However, at the 2nd month of treatment, TBDM patients were more symptomatic compared to patients in the TBNDM group. Conclusions The study showed that DM is associated with increased death during TB treatment. DM has no association with clinical presentation of TB except at the end of the intensive phase treatment. Routine screening of TB patients for DM is recommended for early diagnosis and treatment of patients with TBDM comorbidity

Cytoreductive Surgery and Intraperitoneal Chemotherapy for Colorectal Peritoneal Carcinomatosis : Prognosis and Treatment of Recurrences in a Cohort Study

Background Cytoreductive surgery (CRS) and intraperitoneal chemotherapy (IPC) treatment of colorectal peritoneal carcinomatosis (PC) is gaining acceptance, but controversy remains. The primary aims were to analyze the outcome and prognostic variables of colorectal PC patients treated with CRS and IPC, and to report on the outcome of additional surgical treatments of subsequent recurrences. Methods Patients referred for treatment of colorectal PC between 1996 and 2010 were included in a cohort. The following data was collected: clinicopathological parameters, survival, recurrences, perioperative chemotherapy and type of IPC (hyperthermic intraperitoneal chemotherapy, HIPEC; or sequential postoperative intraperitoneal chemotherapy, SPIC). Multivariable analyses were conducted on potential prognostic factors for overall survival (OS). Results In the 151-patient cohort, the median OS was 34months (range: 2-77) for CRS and HIPEC with five-year survival predicted at 40% (five-year disease-free survival 32%). For CRS and SPIC, the OS was 25months (range: 2-188) with five-year survival at 18%.  Open-and-close patients survived 6months (range: 0-14) with no five-year survival (HIPEC vs. SPIC p=0.047, SPIC vs. open-and-close p&lt;0.001). Adjuvant systemic chemotherapy was a noteworthy independent prognostic factor in the multivariable analysis. OS for patients undergoing additional surgical treatment of recurrences was 25months vs. 10months with best supportive care or palliative chemotherapy (p=0.01). Conclusion Substantial long-term survival is possible in patients with colorectal PC. HIPEC was associated with better OS than SPIC and adjuvant systemic chemotherapy may improve the outcome in patients. Good OS is achievable in selected patients undergoing additional surgical treatment of isolated liver or peritoneal recurrences after prior complete CRS

Assessment of health system challenges and opportunities for possible integration of diabetes mellitus and tuberculosis services in South-Eastern Amhara Region, Ethiopia: a qualitative study

Background The double burden of tuberculosis (TB) and diabetes mellitus (DM) is a significant public health problem in low and middle income countries. However, despite the known synergy between the two disease conditions, services for TB and DM have separately been provided. The objective of this study was to explore health system challenges and opportunities for possible integration of DM and TB services. Methods This was a descriptive qualitative study which was conducted in South-Eastern Amhara Region, Ethiopia. Study participants included health workers (HWs), program managers and other stakeholders involved in TB and DM prevention and control activities. Purposive sampling was applied to select respondents. In order to capture diversity of opinions among participants, maximum variation sampling strategy was applied in the recruitment of study subjects. Data were collected by conducting four focus group discussions and 12 in-depth interviews. Collected data were transcribed verbatim and were thematically analyzed using NVivo 10 software program. Result A total of 44 (12 in-depth interviews and 32 focus group discussion) participants were included in the study. The study participants identified a number of health system challenges and opportunities affecting the integration of TB-DM services. The main themes identified were: 1. Unavailability of system for continuity of DM care. 2. Inadequate knowledge and skills of health workers. 3. Frequent stockouts of DM supplies. 4. Patient’s inability to pay for DM services. 5. Poor DM data management. 6. Less attention given to DM care. 7. Presence of a well-established TB control program up to the community level. 8. High level of interest and readiness among HWs, program managers and leaders at different levels of the health care delivery system. Conclusion The study provided insights into potential health systems challenges and opportunities that need to be considered in the integration of TB-DM services. Piloting TB and DM integrated services in selected HFs of the study area is needed to assess feasibility for possible full scale integration of services for the two comorbid conditions
