Assessing Suitability of a Colorectal Cancer Screening Program in Oman.

Colorectal cancer is among the most common cancers globally and carries a high mortality rate. The incidence of colorectal cancer has been increasing in the Middle East, including in Oman. While many countries have implemented a bowel cancer screening program, Oman has yet to establish one. A standard tool for bowel cancer screening is a fecal immunochemical test where a fecal sample is sent to a laboratory to check for blood content in the feces. In Oman, such fecal test kits are available at the primary health care level, but primary care physicians were unaware of the signs and symptoms or screening methods for colorectal cancer. This review article aims to assess the suitability of a colorectal cancer screening program in Oman using guidelines from the Supporting the Use of Research Evidence (SURE) collaboration.

Does hand mirror morphology a useful diagnostic tool for the treatment decision of acute undifferentiated leukemia at admission?

Abstract: It is difficult how to manage acute undifferentiated leukemia in daily practice, but generally, hand mirror morphology provides ease to treat these patients. Thirty-nine years old male patient was admitted to with the complaints of echymosis, and pain at his left buttock due to an intramuscular injection for the treatment of previously diagnosed of the lower respiratory infection. Peripheral blood smear revealed >%50 blasts cells with a moderate nuclear: cytoplasmic ratio and one or more nucleoli. The blast cells showed a hand-mirror morphology and not harboring auer rods. According to the flow cytometric analysis the blastic cells do not represent to be originated from myeloid or lymphoid origin, because the cells harboring both of two cell lineages. AML-like therapy was commenced based on the positive myeloid markers including CD117 and CD135. Even though hand mirror morphology of the blasts usually demonstrates the lymphoid origin and the patients are treated as ALL like therapy, myeloid blasts rarely represents the same morphology, as was in our patient.

Laboratory Test Utilization Practices in Hamad Medical Corporation; Role of Laboratory Supervisors and Clinicians in Improper Test Utilization; a Descriptive Pilot Study.

Background: The use of diagnostic laboratory tests is increasing worldwide. Improper test utilization (ITU) is a common problem for all healthcare systems as it costs substantial expenses for the health systems and impacts optimal patient care. Purpose: The present small-scale survey aims to highlight the current practice of ITU among the labs and physicians, and investigate the actions of diagnostic laboratories towards ITU, and identify the reasons affecting test ordering decisions among physicians. Methods: A cross sectional study based on two different surveys was developed and distributed from March 2017 to April 2017 to laboratory supervisors and physicians (clinicians) at Hamad Medical Corporation (HMC), Qatar. Fourteen laboratory supervisors and eighty-nine physicians were surveyed about improper test utilization practices. The overall results are descriptive data. Results: The overall proportion of improperly utilized tests detected by the laboratory supervisors were 50.0%, 35.7%, and 14.3% for overused, misused, and underused lab tests, respectively. Among the physicians, 91% used the electronic ordering template to select the appropriate tests. Moreover, 78.7% of the physicians used the clinical guidelines, while 73% were not employing the laboratory handbook. Furthermore, 95.5%% of the physicians preferred to get feedback about inappropriate tests, while 51.1% were not receiving any, and 40.9% were rarely receiving. Finally, 67.4% were unaware of the tests' costs among surveyed physicians, and 63.6% showed a willingness to reduce their orders if the cost was high and unnecessary. Conclusion: The physician's and the laboratories' communication were inadequate and not systematized, causing ITU practices. The improvement strategy should focus on the communication between clinical labs and physicians and enhance physician implementation to order appropriate lab tests. This could be achieved by conducting legitimate educational methodologies, continuous feedback reviews, ongoing audits, executing health information technology instruments, engaging laboratory practice guidelines, and applying demand management and testing algorithms.

Using plasma exchange to successfully manage thyrotoxicosis in a patient with possible antithyroid drug-related thrombotic thrombocytopenic purpura.

OBJECTIVE: Thrombotic thrombocytopenic purpura (TTP) is a rare disease characterized by microangiopathic hemolytic anemia, thrombocytopenic purpura, neurologic abnormalities, fever, and renal insufficiency. The association or co-existence of thyrotoxicosis or antithyroid drugs with TTP has not been previously reported. Subject and Results. Herein, we present a 54-year-old female patient newly diagnosed with toxic multinodular goiter accompanying with TTP, possibly triggered by either thyrotoxicosis or antithyroid drugs. CONCLUSIONS: The present report is the first in the literature to demonstrate the co-existence of these two diseases and the use of plasma exchange as a modality to treat both conditions.

A Successful Renal Transplantation Case After Stem Cell Transplantation.

Renal transplantation is the most effective treatment method for end-stage renal disease (ESRD). However, new treatment modalities are being investigated, such as immunotoleration, to avoid the acute and chronic side effects of immunosuppressant drugs. We report a case in which a man had undergone allogenic stem cell transplantation from his brother 16 years ago due to chronic myeloid leukemia, and who then developed ESRD due to arterial hypertension and underwent renal transplantation (Rtx) from the same brother. The patient was followed up without immunosuppression due to full chimerism.

American Society for Gastrointestinal Endoscopy guidelines for appropriate use of colonoscopy: are they suitable for African patients?

This study investigates the appropriateness and diagnostic yield of colonoscopy referrals in an African setting using the American Society of Gastrointestinal Endoscopy guidelines: a prospective, descriptive, cross-sectional hospital-based study. A total of 311 patients were included in the study; 228 referrals (73.3%) were considered appropriate and clinically significant pathology was found in 157 patients, giving an overall diagnostic yield of 50.5%. Diagnostic yield in those with appropriate referrals was 58.8% and 27.7% (P = 0.004) in those with inappropriate referrals. In our setting these guidelines are useful in improving diagnostic yield and reducing the rate of inappropriate referrals for colonoscopy. However, patients above the age of 50 presenting with lower gastrointestinal symptoms should undergo a colonoscopy even if the indication was inappropriate, especially in countries which are not implementing colorectal cancer screening programmes for average risk patients.
