Hospitalization and Post-hospitalization Outcomes Among Teaching Internal Medicine, Employed Hospitalist, and Locum Tenens Hospitalist Services in a Tertiary Center: a Prospective Cohort Study.

BACKGROUND: There are no prospective studies comparing hospitalization and post-hospitalization outcomes between teaching internal medicine services and non-teaching hospitalists, and no prospective studies comparing these outcomes between locum and employed hospitalists. OBJECTIVE: To compare the length of stay, hospital costs readmission rate, and mortality rate in patients treated by teaching internal medicine services vs. hospitalists and among patients treated by locum vs. employed hospitalists. DESIGN: Prospective cohort study. Propensity score was used to obtain weighted estimates. SETTING: Referral center. PATIENTS: All patients 18 years and older admitted to internal medicine services. INTERVENTION: Treatment by teaching internal medicine services vs. hospitalists. Treatment by locum hospitalists vs. employed hospitalists. MAIN MEASURES: Primary outcome was adjusted length of stay and secondary outcomes included hospital cost, inpatient mortality, 30-day all-cause readmission, and 30-day mortality. KEY RESULTS: A total of 1273 patients were admitted in the study period. The mean patient age was 61 ± 19 years, and the sample was 52% females. Teaching internal medicine physicians admitted 526 patients and non-teaching hospitalists admitted 747 patients. Being seen exclusively by teaching internal medicine physicians comports with a shorter adjusted hospital stay by 0.6 days (95% CI - 1.07 to - 0.22, P = .003) compared to non-teaching hospitalists. Adjusted length of stay was 1 day shorter in patients seen exclusively by locums compared to patients seen exclusively by employed services (95% CI - 1.6 to - 0.43, P < .001) with an adjusted average hospital cost saving of 1339 dollars (95% CI - 2037 to - 642, P < .001). There was no statistically significant difference in other outcomes. CONCLUSIONS: Teaching internal medicine services care was associated with a shorter stay but not with increased costs, readmission, or mortality compared to non-teaching services. In contrary to the "expected," patients treated by locums had shorter stays and decreased hospital costs but no increase in readmissions or mortality.

Spontaneous subdural hematoma in a patient with Philadelphia chromosome-positive acute lymphoblastic leukemia with normal platelet count after dasatinib treatment.

Dasatinib, which is an inhibitor of BCR-ABL and SRC family tyrosine kinases, is used for the treatment of patients with Philadelphia chromosome (Ph) positive leukemia, especially for those who develop resistance or who are intolerant to imatinib. The most common adverse effects attributed to its use are: myelosuppression, nausea, diarrhea, and peripheral edema. Hemorrhage, which could be gastrointestinal, genitourinary or central nervous system, is a less frequent adverse effect. In this case, we report a patient affected by precursor B-cell acute lymphoblastic leukemia (ALL) positive for the Ph chromosome translocation treated with the tyrosine kinase inhibitor (TKI) dasatinib. During the treatment with dasatinib the patient developed subdural hematoma (SDH). She did not have any head trauma, thrombocytopenia, coagulopathy or meningeal involvement, making dasatinib-induced platelet dysfunction the most likely cause of SDH.

Bilateral Retinal Vasculitis as the First Presentation of Systemic Lupus Erythematosus.

BACKGROUND Systemic lupus erythematosus (SLE) can involve any part of the eye. Keratoconjunctivitis sicca (dry eye) is the most common ocular manifestation, followed by scleritis, episcleritis, and retinitis. Retinal disease affects around 10% of patients with SLE. Mild retinopathy may be asymptomatic. However, severe cases can cause visual loss requiring urgent ophthalmic evaluation. CASE REPORT We present a case of bilateral retinal vasculitis as the presenting manifestation of SLE. A 14-year-old girl with a history of schizophrenia presented to the emergency department (ED) with generalized weakness. Four days before her presentation, she developed itching in her eyes and frontal headaches. In the ED, she reported blurry vision in her left eye only and diffuse arthralgia. The ophthalmic evaluation showed bilateral reduced visual acuity, worse in the left eye. Both eyes had diffuse hemorrhages, white retinal lesions, and blurred optic disc margins. She was diagnosed with panuveitis and retinal vasculitis. The patient was then found to have SLE, diagnosed by the presence of arthralgias, panuveitis, severe bilateral retinal vasculitis, positive ANA and anti-dsDNA, and normocytic anemia. The patient received intravenous methylprednisolone with subsequent oral prednisone upon discharge, hydroxychloroquine, and azathioprine. One year after her presentation, she had significant visual improvement and no other system involvement. CONCLUSIONS Retinal vasculitis, as the presenting symptom of SLE, has been overlooked in large studies. However, the number of case reports documenting this as a presenting symptom, often with minimal or no organ involvement, suggests that upon diagnosis, patients might benefit from a skilled ophthalmic evaluation.

Type-B lactic acidosis associated with progressive multiple myeloma.

We report a 64-year-old lady with stage II, Immunoglobulin-G lambda multiple myeloma (MM) (standard risk), who presented with type-B lactic acidosis (LA), and multi-organ dysfunction associating myeloma progression, and ending in imminent death. In the context of literature review of all previously reported similar cases, this report highlights and discusses the association of type-B LA and MM (especially progressive disease), and also emphasizes the poor outcome. Early recognition of this condition with intensive supportive care, and treatment of multiple myeloma may improve outcomes.
