Melanoma can occur as a metastasis within subcutaneous tissue, lymph nodes, or viscera without a detectable primary tumor. Among patients with metastatic melanoma of unknown primary lesion, those with endobronchial metastasis are exceedingly rare. Herein we report a case of an endobronchial and pulmonary metastasis in a patient with melanoma originating from an unknown primary site. The patient without a previous history of melanoma presented with blood-tinged sputum. Fiberoptic bronchoscopy revealed a black polypoid tumor obstructing the posterior basal segmental bronchus of the right lower lobe. A final diagnosis of the malignant melanoma was made based on an immunohistochemical study of the bronchoscopic biopsy specimen. Skin, ophthalmic, oral, and nasal examinations failed to identify occult primary lesions. Subsequent evaluation including positron emission tomography/computed tomography scans did not uncover any abnormalities other than the metastatic pulmonary melanoma. We also describe the characteristic bronchoscopic features of melanoma.

We present a case of a 13-year-old boy with Gorham's disease involving the thoracic and lumbar spine, femur, and gastrointestinal (GI) tract, which was complicated by recurrent chylothorax and GI bleeding. The presenting symptoms were intermittent abdominal pain, back pain, and melena. Esophagogastroduodenoscopy and colonoscopy showed no abnormal lesions, but duodenal biopsy showed marked dilation of the lymphatics in the mucosa and submucosa, which revealed positive staining with a D2-40 immunohistochemical marker. In cases of GI bleeding with osteolysis, the expression of a D2-40 marker in the lymphatic endothelium of the GI tract may help to diagnose GI involvement in Gorham's disease. To the best of our knowledge, this is the first case report to pathologically demonstrate intestinal lymphatic malformation as a cause of GI bleeding in Gorham's disease.

We report a 10-year-old girl with the blue rubber bleb nevus syndrome (BRBNS) who had chronic severe anemia caused by chronic occult bleeding in the gastrointestinal (GI) tract. The patient was admitted to the hospital frequently for recurrent pallor and fatigue since the age of 7 years. Gastroduodenoscopy and capsule endoscopy revealed multiple venous malformations with blood oozing in the stomach, small bowel and colon. The patient was treated by aggressive surgical resection of the 23 vascular malformations in the GI tract. The patient is well without anemia 15 months post surgery.

The aim of the study was to evaluate of the knowledge, behavior and health beliefs of individuals over 50 regarding colorectal cancer screening, with a descriptive and cross-sectional design at Karabuk Life and Health Center in Turkey. A total of 160 people meeting set criteria were included in the study. The questionnaire consisted of two parts. The first part was composed of questions on characteristics of participants and the second part of questions derived from the Champion's Health Belief Model Scale. Only 15.0% of participants (n=24) had undergone a fecal occult blood test (FOBT), 11.3% (n=18) had had colonoscopy and 4.4% (n=7) had had sigmoidoscopy. Some 90.6% of the participants had low levels of risk awareness about the colorectal cancer. It was found that the average point of severity subscale of participants over 65 is higher than that of participants under 65 (p<0.05). In conclusion, because of the many barriers and health beliefs for the colorectal cancer screening program, the rate of participation in screening programs is not sufficient. Healthcare providers have important responsibilities for increasing rate of attendance in colorectal cancer screening programs.

The urinalysis is an essential part of the diagnostic work-up for kidney disease and other renal system disorders. The dipstick test allows rapid and simultaneous chemical analyses of urine, including factors such as pH, specific gravity, protein, glucose, ketones, occult blood, bilirubin, urobilinogen, nitrite, and leukocyte-esterase. The chemical reactions on dipstick are complicated and can be affected by oxidizing, reducing, and discoloring substances in the urine. Therefore, false positive and false negative results are common in dipstick testing. To obtain reliable results with the dipstick, it is necessary to collect urine cleanly and examine the urine carefully. It is mandatory to clearly understand the principles of dipstick testing to evaluate abnormal findings. If the urine dipstick results suggest hematuria, proteinuria, or urinary tract infection, microscopy of the urine should be performed to confirm the findings.

Purpose: Even though the incidence of colorectal cancer (CRC) has increased in Korea, the colorectal cancer screening (CRCS) is lower than that of other cancer screenings. The purpose of this study was to identify CRCS rate and to predict factors in blue-color workers. Methods: A descriptive survey design was employed. Data were collected with 327 workers, recruited from 32 companies, aged 40 and over using questionnaire from August 2010 to January 2011. Collected information included CRCS, demographic characteristics, job characteristics, health behaviors, and interpersonal relationship. The definition of CRCS included fecal occult blood test (FOBT), colonoscopy, or double contrast barium enema (DCBE). Results: Among 94 workers receiving CRCS, workers having FOBT were 37, colonoscopy were 28, and DCBE was 6 in the past. Workers who aged over 50 (OR=2.30, 95% CI=1.11-4.77), middle school educated (OR=0.30, 95% CI=0.14-0.65), less working hours (OR=0.98, 95% CI=0.96- 0.99), and had family members who carried out regular cancer screening (OR=1.89, 95% CI=1.01-3.55) were more likely to perform CRCS. Conclusion: The findings suggest that the information and notice about CRCS to increase screening uptake, providing the accessible screening method, and involving company administrators or health managers might be useful to increase the CRCS rate in workers.

Background: A colorectal cancer screening program was piloted in two districts of Kedah in 2013. There is scarcity of information on colorectal cancer screening in Malaysia. Objective: Thus, this research was conducted to evaluate the colorectal cancer screening program in the districts to provide insights intop its efficacy. Materials and Methods: A cross sectional study was conducted using data on the colorectal cancer screening program in 2013 involving Kota Setar and Kuala Muda districts in Malaysia. We determined the response rate of immunochemical fecal occult blood test (iFOBT), colonoscopy compliance, and detection rates of neoplasia and carcinoma. We also compared the response of FOBT by demographic background. Results: The response rate of FOBT for first iFOBT screening was 94.7% while the second iFOBT screening was 90.7%. Participants from Kuala Muda district were 27 times more likely to default while Indians had a 3 times higher risk of default compared to Malays. The colonoscopy compliance was suboptimal among those with positive iFOBT. The most common finding from colonoscopy was hemorrhoids, followed by tubular adenoma. Detection rate of carcinoma and neoplasia for our program was 1.2%. Conclusions: In summary, the response rate of iFOBT was encouraging but the colonoscopy compliance was suboptimal which led to a considerably low detection rate.

The incidence of colorectal cancer has been increasing in many Asian countries including Malaysia during the past few decades. A physician recommendation has been shown to be a major factor that motivates patients to undergo screening. The present study objectives were to describe the practice of colorectal cancer screening by primary care providers in Malaysia and to determine the barriers for not following recommendations. In this cross sectional study involving 132 primary care providers from 44 Primary Care clinics in West Malaysia, self-administered questionnaires which consisted of demographic data, qualification, background on the primary care clinic, practices on colorectal cancer screening and barriers to colorectal cancer screening were distributed. A total of 116 primary care providers responded making a response rate of 87.9%. About 21% recommended faecal occult blood test (FOBT) in more than 50% of their patients who were eligible. The most common barrier was "unavailability of the test". The two most common patient factors are "patient in a hurry" and "poor patient awareness". This study indicates that colorectal cancer preventive activities among primary care providers are still poor in Malaysia. This may be related to the low availability of the test in the primary care setting and poor awareness and understanding of the importance of colorectal cancer screening among patients. More awareness programmes are required for the public. In addition, primary care providers should be kept abreast with the latest recommendations and policy makers need to improve colorectal cancer screening services in health clinics.

Background: Calprotectin in feces seems to be a more sensitive marker for gastrointestinal (GI) cancers than fecal occult blood, but its specificity may be too low for screening average risk populations. This study aims at evaluating the diagnostic value of fecal calprotectin as a screening biomarker for GI malignancies. Materials and Methods: In a case-control study, 100 patients with GI malignancies (50 patients with colorectal cancer and 50 patients with gastric cancer) and 50 controls were recruited in Tabriz Imam Reza and Sina hospitals during a 24-month period. One to two weeks after the last endoscopy/colonoscopy, fecal specimens were collected by the patients and examined by ELISA method for quantitative measurement of calprotectin content. The results were compared between the three groups. Results: The mean fecal calprotectin level was $109.1{\pm}105.3$ (2.3-454.3, median:74), $241.1{\pm}205.2$ (3.4-610.0, median:19.3) and $45.9{\pm}55.1{\mu}g/g$ (1.3-257.1, median:19.3) in gastric cancer, colorectal cancer and control group, respectively, the differences being significant (p<0.001) and remaining after adjustment for age. The optimal cut-off point for fecal calprotectin was ${\geq}75.8{\mu}g/g$ for distinguishing colorectal cancer from normal cases (sensitivity and specificity of 80% and 84%, respectively). This value was ${\geq}41.9{\mu}g/g$ for distinguishing gastric cancer from normal cases (sensitivity and specificity of 62%). Conclusions: Our results revealed that fecal calprotectin might be a useful and non-invasive biomarker for distinguishing colorectal cancer from non-malignant GI conditions. However, due to low sensitivity and specificity, this biomarker may not help physicians distinguishing gastric cancer cases from healthy subjects.
