A REVIEW OF TREATMENT, RISK FACTORS, AND INCIDENCE OF COLORECTAL CANCER

Colorectal cancer (CRC) is considered as the third most frequent cancer in the world and the incidence increases with increasing age. CRC accounts for nearly 9 % of all cancer incidence, with an estimated 1.4 million cases happening in 2012. The aim of this paper is to provide a review of incidence, risk factors, screening strategies, and treatment of colorectal cancer. We searched the studies in five English databases, including Web of Science, PubMed, Scopus, EMBASE, and Google Scholar with no limitation in publication time to find all papers regarding colorectal cancers. Papers with any language were included in the first step of search if they had an English abstract. We used the following words and terms including colorectal cancer, treatment, risk factor, diagnosis, chemotherapy, radiotherapy, surgery. Geographical variations and different time courses in the CRC incidence indicate that environmental factors and lifestyle are major factors in the development of this disease. The main preventable risk factors for CRC are nutrition, a high-fat diet, a low-fiber diet, obesity and physical inactivity, smoking and alcohol consumption, aspirin and nonsteroidal anti-inflammatory drugs, and some non-preventable risk factors such as age, gender, race, and diabetes mellitus. Colonoscopy remains the study of choice to diagnose colorectal cancer. Prior to any treatment, CT imaging of chest, abdomen and pelvis with contrast is needed for staging the patient’s CRC. The preferred option for localized colorectal cancer is surgery (etc, laparoscopic surgery, colostomy for rectal cancer); whereas the adjuvant chemotherapy is generally recommended for patients with lymph node metastases. Targeted treatment of colorectal cancer by monoclonal antibodies are important bioengineered proteins that can help the body's natural immune response to detect, attack, and kill cancer cells. Monoclonal antibodies may be used alone or in combination with other treatments such as chemotherapy. CRC accounts an important health problem worldwide that is estimated to increase because of the growth and aging of the population, and because of the adoption of at-risk manners and lifestyles, particularly in economically less developed countries. Screening has been confirmed to significantly decrease mortality and can prevent the onset of the disease. More international efforts are required to situate into practice targeted prevention approaches that might reduce the burden of CRC worldwide.

Educational counselling of patients with combined TB and diabetes mellitus: a randomised trial

SETTING: Newly diagnosed pulmonary TB with diabetes mellitus (DM) comorbidity attending clinics in Bandung City, Indonesia.OBJECTIVE: To describe the effect of educational counselling on patients’ knowledge about TB (transmission, treatment, risk factors) and DM (symptoms, treatment, complications, healthy lifestyle), adherence to medication, and to assess characteristics associated with knowledge.DESIGN: All patients received counselling and were then randomised to either structured education on TB-DM, combined with clinical monitoring and medication adjustment (intervention arm), or routine care (control arm). Knowledge and adherence were assessed using a questionnaire.RESULTS: Baseline and 6-month questionnaires were available for 108 of 150 patients randomised (60/76 in the intervention arm and 48/74 in the control arm). Patients knew less about DM than about TB. There was no significant difference in the proportion with knowledge improvement at 6 months, both for TB (difference of differences 14%; P = 0.20) or for DM (10%; P = 0.39) between arms. Intervention arm patients were more likely to adhere to taking DM medication, with fewer patients reporting ever missing oral DM drugs than those in the control arm (23% vs. 48%; P = 0.03). Higher education level was associated with good knowledge of both TB and DM.CONCLUSIONS: Structured education did not clearly improve patients’ knowledge. It was associated with better adherence to DM medication, but this could not be attributed to education alone. More efforts are needed to improve patients’ knowledge, especially regarding DM.

Dropping risk stratification with subsequent treatment-risk paradox in non ST elevation acute coronary syndromes: a clinical audit in Iraq

Background Risk stratification is the cornerstone in managing patients with Non-ST Elevation Acute Coronary Syndromes (NSTE-ACS) and can attenuate the unjustified variability in treatment and guide the intervention decision notwithstanding its impact on better healthcare resources use. This study sought to disclose real adherence to guidelines in risk stratification of NSTE-ACS patients and in adopting intervention decision in practice. Methods Multicentre prospective study recruited NSTE-ACS patients. Baseline characteristics were collected, TIMI (Thrombolysis in Myocardial Infarction) and GRACE (Global Registry of Acute Coronary Events) scores were calculated, management strategy as well as timing to intervention were recorded. Results n. = 150, 72% of them were males, mean age was (59 ± 12.32) years. TIMI score was calculated in 5.3% of patients with none of them had GRACE score calculated. Invasive strategy was adopted in 85.24 and 82.7% of low GRACE and TIMI risk categories respectively, while invasive approach used in 42.85 and 40% of high GRACE and TIMI risk categories respectively. The immediate intervention in less than 2 hours was more to be used in low-risk categories while the high-risk and very high-risk patients whom were managed invasively were catheterized within >72 h; or more frequently to be non-catheterized at all. Sixty percent of those with acute heart failure, 80.76% of those with ongoing chest pain, 85% of those with dynamic ST changes same as 80% of those with cardiogenic shock were treated conservatively. Using multivariable analysis older age, ongoing chest pain and cardiogenic shock predicted conservative approach. Conclusions There is striking underuse of risk scores in practice that can contribute to treatment-risk paradox in managing NSTE-ACS in form of depriving those with higher risk from invasive strategy despite being the most beneficiaries. The paradox did not only involve the very high-risk patients but also the very high-risk criteria like ongoing chest pain and cardiogenic shock predicted conservative approach, this highlights that the entire approach to patients with NSTE-ACS should be reconsidered, regardless of the use of risk scores in clinical practice. Audit programs activation in middle eastern countries can inform policymakers to put a limit to the treatment-risk paradox for better cardiovascular care and outcomes.

Prognostic validity of the Periapical and Endodontic Status Scale for the radiographically assessed 2-year treatment outcomes in teeth with apical periodontitis: a prospective clinical study

Background Endodontic treatment planning and treatment success evaluation are largely based on radiographic assessment of anatomical and treatment-related parameters of teeth with apical periodontitis (AP). This prospective clinical study aimed to assess radiographically the 2-year endodontic treatment outcomes for teeth with AP, and to evaluate prognostic validity of Periapical and Endodontic Status Scale (PESS). Methods A total of 128 patients, representing 176 teeth with AP were examined by cone-beam computed tomography at baseline and at 24 months after endodontic treatment. Treatment outcome was evaluated using estimates of periapical radiolucency and the relationship between anatomical structures and location. The strength of the associations between these and treatment-related parameters was tested by logistic regression analysis. PESS sensitivity and specificity were calculated for every treatment risk group (low, moderate, high) of teeth. Results One hundred and fifty-seven teeth, representing 350 root canals had a positive treatment outcome, while 19 teeth, representing 53 root canals had a negative treatment outcome at 24 months. The probability of negative outcome was 25 times higher in the moderate/high-risk group than in the mild-risk group of teeth (OR = 25.1; 95%CI [12.2–51.5]). Pre-treatment complications and retreatment cases with radiolucency were associated with negative outcomes (OR = 35.9; 95%CI [12.6–102.4]; OR = 26.437; 95%CI [10.9–64.1], respectively). PESS sensitivity and specificity was over 80% in all risk groups except for high risk group, due to very low number of cases. Conclusions Endodontic treatment outcome depends on the severity of periapical changes. The presence of complications and retreatment cases with periapical lesions are associated with negative treatment outcome. The PESS is a valid instrument to predict outcome of teeth with low-moderate treatment risk of AP.

Combined Korean Medicine Treatment of a Rare Case of Burst Fracture in an Elderly Patient with Kissing Spine

A burst fracture refers to the fracture of the anterior and middle vertebral columns which are moving into the spinal canal causing neurological impairments, generally requiring surgical treatment. We herein report a rare case of burst fracture with kissing spine in a 90-year-old man who had severe lower back pain that worsened during back extension. Considering the surgical treatment risk, he was hospitalized at a Korean medicine hospital for 85 days and underwent combined Korean medicine treatments including pharmacopuncture, herbal medicine, chuna, deep-fascia meridian therapy, walking practice, and abdominal breathing. Based on patient-reported scales, his pain was alleviated, and his physical function improved. Furthermore, his range of motion and walking time increased. This case report suggests that combined Korean medicine treatments could be an effective alternative for patients with burst fracture who have surgery risks.
