Admission,recruitment, and retention

As the country strives to produce larger numbers of generalist physicians, considerable controversy has arisen over whether or not generalist applicants can be identified, recruited, and influenced to keep a generalist-oriented commitment throughout medical training. The authors present new and existing data to show that: 1) preadmission (BA/MD or post-baccalaureate) programs can help to identify generalist-oriented students; 2) characteristics determinedat admission to medical school are predictive of future generalist career choice; 3) current inpatient-oriented training programs strongly push students away from a primary care career; 4) women are more likely than men to choose generalist careers, primarily because of those careers’ interpersonal orientation; and 5) residency training programs are able to select applicants likely to become generalists. Therefore, to produce more generalists, attempts should be made to encourage generalist-oriented students to enter medical schools and to revise curricula to focus on outpatient settings in which students can establish effective and satisfying relationships with patients. These strategies are most likely to be successful if enacted within the context of governmental and medical school-based changes that allow for more reimbursement and respect for the generalist disciplines.     

Perianal infections: Reader agreement and diagnostic performance of fat‐suppressed contrast‐enhanced MRI

We aimed to determine the diagnostic performance of the contrast‐enhanced fat‐suppression technique in the detectability of perianal infections and to compare this technique with different MR sequences used for this purpose. Thirty consecutive patients with clinically suspected anorectal infections were examined with fast spin‐echo (FSE) T2‐weighted, short‐inversion‐time inversion recovery (STIR), and fat‐suppressed and non‐fat‐suppressed T1‐weighted spoiled gradient‐echo (SGE) (in‐phase) dynamic contrast‐enhanced sequences. The results of MRI were correlated with the findings of surgery, which was considered as the standard of reference. Receiver‐operating‐characteristic curves were reconstructed to describe and compare the diagnostic value of each MR technique. The values of kappa were used as a measure of observer reliability. Diagnostic performances of STIR, FSE T2‐weighted and fat‐suppressed and non‐fat‐suppressed, contrast‐enhanced SGE T1‐weighted techniques showed statistically insignificant differences in detection of perianal infections. There was almost perfect interobserver agreement regarding the presence of lesions on each MR technique. Fat‐suppressed, contrast‐enhanced SGE T1‐weighted MRI showed adequate diagnostic performance in the detection of perianal infections. However, its significance is not different from the other MR sequences used for the present study.     

Acute Lymphoblastic Leukemia as a Second Malignant Neoplasm in a Child with Medulloblastoma

Second malignant neoplasm in childhood is increasing due to advances in therapy modalities. Acute lymphoblastic leukemia as a second malignancy following the treatment of medulloblastoma is a very rare condition. A 13-year-old boy was diagnosed as acute lymphoblastic leukemia following radiotherapy and chemotherapy for treatment of medulloblastoma.

Effects of acute kidney injury on clinical outcomes in patients with upper gastrointestinal bleeding

Aim Upper gastrointestinal bleeding (UGIB) is a very frequently encountered condition that has a high morbidity and which increases treatment costs. Duration of hospital stay and mortality increases in patients with UGIB complicated by acute kidney injury (AKI). The aim of this study was to reveal risk factors in patients with UGIB developing AKI and to compare clinical outcomes and hospital costs between patients with UGIB developing AKI and those with UGIB not developing AKI.

Material and methods This retrospective study included 245 patients admitted to the emergency unit and the intensive care unit for internal diseases at Ankara Numune Education and Research Hospital, Turkey. Results The difference in mortality rates between the patients with AKI and those without AKI was significant (p?0.001). The mean duration of intensive care unit stay was 0.2?±?1.1 days in the patients without AKI (n?=?143) and 2.5?±?5.6 days in the patients with AKI. It was significantly higher in the patients with AKI (p?0.001). Hospital stay was significantly longer in the patients with AKI than those without AKI, and as severity of AKI increased, hospital stay became considerably longer (p?0.001). Hospital costs were significantly higher in the patients with AKI than those without AKI, and as severity of AKI increased, hospital costs considerably rose (p?0.001). Conclusion AKI is a condition that lengthens hospital stay, increases hospital costs and creates a burden on health care systems. Detect kidney injury earlier and administering an appropriate treatment can improve clinical outcomes in patients with UGIB developing AKI.
