Henoch-Schonlein Purpura, an Unusual Presentation of Acute Myeloid Leukemia.

BACKGROUND/AIM: Acute myeloid leukemia (AML) is a hematologic malignancy that accounts for most annual deaths from leukemias in the United States. Although rare, cutaneous manifestations may be the first clinical sign of AML. Henoch Schonlein Purpura (HSP), as a manifestation of AML, has an unknown incidence. Here, we present a case of HSP as the presenting manifestation of AML. CASE REPORT: A 58-year-old woman presented to the Emergency Department with a rash and itching of all her extremities. The rash began on her thighs and arms a month prior and gradually spread distally. On presentation, she appeared alert and was hemodynamically stable. Skin examination revealed palpable purpura and plaques, with petechiae involving all extremities. Admission labs revealed a hemoglobin and hematocrit of 8 g/dl and 24% respectively. The white blood cell count was 1.23 k/mcl, absolute neutrophil count was 0.31 k/mcl, and platelets were 172,000 k/mcl. A broad work-up was carried out. Subsequently, skin and bone marrow biopsies were performed. Skin biopsy was positive for vascular immune reactivity with IgA, consistent with HSP. The bone marrow biopsy revealed hypocellular marrow with atypical blast infiltrates constituting 10-15% of cellularity, indicating AML. The patient was transferred to malignant hematology service where and started on induction chemotherapy for AML. CONCLUSION: Prompt diagnosis and treatment of AML is crucial for better clinical outcomes. Our case suggests that HSP can be a rare presenting manifestation of AML. It is important to consider hematologic malignancy in patients presenting with HSP in the right clinical context as part of differential diagnosis.

Characteristics and Outcomes of COVID-19 Patients Admitted to Intensive Care Units in a Large Health System in Western Pennsylvania.

Importance Despite growing literature, there is still limited understanding of factors that can predict outcomes in coronavirus disease 2019 (COVID-19) patients who require intensive care. Objective To evaluate the characteristics of COVID-19 patients admitted to the intensive care unit (ICU) and identify their associations with outcomes. Background There are limited data on the outcomes in COVID-19 patients in Pennsylvania. Design Retrospective study Setting Intensive care units in an academic health system in Western Pennsylvania. Participants Patients with reverse transcriptase-polymerase chain reaction (RT-PCR)-confirmed COVID-19 admitted to ICUs as direct admission or transfers from regular floors between March 1, 2020, and April 30, 2020. Main outcome(s) and measure(s) The primary outcome was inpatient mortality. Secondary outcomes included complications during ICU stay, hospital length of stay, discharge disposition, and the need for oxygen at discharge. Categorical variables are described as frequencies and continuous variables as median with interquartile range (IQR). Regression modeling was used to identify the predictors of inpatient mortality in these patients. P-value <0.05 was considered statistically significant. Analysis was performed using Stata version 15.1 (StataCorp, College Station, Texas). Results The cohort included 58 consecutive patients, with a median age of 62 years (IQR 54-73), 63.8% of which were male. On presentation, constitutional symptoms were the most common (91.4%), followed by lower respiratory tract symptoms (87.9%). Tachypnea (65.5%) and hypoxia (67.2%) were the most common abnormal vital signs at presentation. Common comorbidities were cardiovascular disease (74.1%), obesity (53.5%), and diabetes (39.7%). The median Acute Physiology and Chronic Health Evaluation (APACHE) score on admission to ICU was 11 (IQR 8.5-17.5). The major complications included acute respiratory distress syndrome (ARDS) 50.0%, shock 41.4%, and acute kidney injury 41.4%. The proportion of patients who underwent mechanical ventilation, required vasopressors, or were on renal replacement therapy were 58.6%, 41.4%, and 10.3%, respectively. Overall mortality was 32.8%. Age, Charlson-comorbidity index, tachypnea, lymphopenia at presentation, high APACHE score, shock, ARDS, mechanical ventilation, and steroid use were significantly associated with mortality. Of the patients who survived their ICU stay, 63.2% were discharged home and 44.7% had a new oxygen requirement at discharge. Conclusion and relevance Our study reports high mortality in COVID-19 patients requiring ICU care in Western Pennsylvania. Identifying factors associated with poor prognosis could help risk-stratify these patients. Prospective studies are needed to assess whether early risk stratification and triaging result in improved outcomes.

Risk Factors for Unnecessary Antibiotic Prescribing for Acute Respiratory Tract Infections in Primary Care.

OBJECTIVE: To determine independent risk factors for inappropriate antibiotic prescribing for acute respiratory tract infections (ARIs) in internal medicine (IM) residency-based primary care offices. PATIENTS AND METHODS: A retrospective study was conducted to measure antibiotic prescribing rates, and multivariable analysis was utilized to identify predictors of inappropriate prescribing among patients presenting to IM residency-based primary care office practices. Patients with an office visit at either of 2 IM residency-based primary care office practices from January 1, 2016, through December 31, 2016, with a primary encounter diagnosis of ARI were included. RESULTS: During the study period, 911 unique patient encounters were included with 518 for conditions for which antibiotics were considered always inappropriate. Antibiotics were not indicated in 85.8% (782 of 911) of encounters. However, antibiotics were prescribed in 28.4% (222 of 782) of these encounters. Inappropriate antibiotic prescribing occurred in 111 of 518 (21.4%) encounters for conditions for which antibiotics are always inappropriate. Using multivariable logistic regression analysis to assess for independent risk factors when adjusted for other potential risk factors for office visits at which antibiotics were not indicated, IM resident-associated visits (odds ratio, 0.25; 95% CI, 0.18-0.36) was the only variable independently associated with lower risk of inappropriate antibiotic prescribing. CONCLUSION: For ARI visits at which antibiotics were not indicated, IM resident comanagement was associated with lower rates of inappropriate prescribing.

Significance of Crescentic Glomeruli in Acute Kidney Injury with Rheumatoid Arthritis.

Crescentic glomerulonephritis (GN) without immune reactants or deposits (referred to as pauci-immune) is typically characterized by the presence of anti-neutrophilic cytoplasmic antibodies (ANCA). While ANCA-negative patients might be expected to have a more benign course, they often have poor renal outcomes, especially without treatment with steroids and immune-modulating therapy. Pauci-immune crescentic GN can also co-exist with other autoimmune conditions, including rheumatoid arthritis (RA). Here, we describe an ANCA-negative patient with RA who developed dialysis-requiring acute kidney injury (AKI) with findings consistent with focal pauci-immune crescentic GN (i.e., no IgG or immune complex on kidney biopsy). Coexistent conditions included Klebsiella sepsis attributed to pneumonia, rhabdomyolysis, leukocytoclastic immune-mediated skin vasculitis, and positive ANA. He had spontaneous improvement in renal function without immunosuppressive therapy. This crescentic GN was not associated with poor renal outcome as AKI resolved with supportive care and treatment of his infection. The AKI was likely multifactorial with co-existing acute tubular necrosis in the setting of Kebsiella sepsis and rhabdomyolysis, and the crescentic GN was felt more likely to be related to the infection rather than having a primary role. This case highlights the importance of viewing crescentic GN in the context of the clinical picture, as it may not always lead to the need of aggressive immune suppression and is not a universally poor prognostic kidney finding. However, these cases do warrant close follow-up as our patient had recurrent RA disease manifestations over the next 2 years that eventually led to his death from severe pulmonary hypertension.

Adherence to Two Large-Bore Intravenous Lines in Acute Gastrointestinal Bleeding Is Low.

BACKGROUND: While the available literature recommends placement of two large-bore intravenous (2LBIV) lines in every patient presenting with acute GIB, the adherence and impact of this recommendation have never before been reported. AIMS: We designed a quality improvement project to assess whether the patients presenting to our institution with acute GIB have appropriate intravenous (IV) access or not. METHODS: We conducted a prospective, observational study, of all patients presenting to our emergency department with overt GIB over a 2-month period. Data analysis was performed, and based on the results, an intervention plan was developed and executed. Post-intervention data collection was done over a 3-month period. Our interventions included physician and nursing education, placing posters in the emergency department, and creation of an order set in the electronic medical record system. RESULTS: A total of 46 patients were in the pre-intervention group, and 71 patients were in the post-intervention group. The presence of 2LBIV lines in the pre-intervention group was only 19.5%, which improved to 36.6% in the post-intervention group (p = 0.049). Factors associated with placement of 2LBIV lines were being in the post-intervention group and admission to the intensive care unit. CONCLUSION: The relatively simple and cost-effective intervention of placing 2LBIV lines is not often executed. We suggest that specific mention of 2LBIV placement in guidelines from national gastroenterology societies might improve compliance in this aspect.

Unexpected cause of fever in a patient with untreated HIV.

We report a case of a 27-year-old man with a history of untreated HIV who presented with fever, rash and leg cramps. Initial suspicion was high for an infectious process; however, after an exhaustive evaluation, thyrotoxicosis was revealed as the aetiology of his symptoms. Recent intravenous contrast administration complicated his workup to determine the exact cause of hyperthyroidism. Differentiation between spontaneously resolving thyroiditis and autonomous hyperfunction was paramount in the setting of existing neutropenia and the need for judicious use of antithyroid therapy. The inability to enlist a nuclear scan in the setting of recent iodinated contrast administration prompted alternative testing, including thyroid antibodies and thyroid ultrasound. In this case, we will discuss the diagnostic challenges of thyrotoxicosis in a complex patient, the sequelae of iodine contrast administration, effects of iodine on the thyroid and the predictive value of other available tests.

Bi-directional hepatic hydrothorax.

A 59-year-old male with alcoholic cirrhosis presented to our hospital with an acutely painful umbilical hernia, and 4 mo of exertional dyspnea. He was noted to be tachypneic and hypoxic. He had a massive right sided pleural effusion with leftward mediastinal shift and gross ascites, with a tense, fluid-filled, umbilical hernia. Emergent paracentesis with drain placement and a large volume thoracentesis were performed. Despite improvement in dyspnea and drainage of 15 L of ascitic fluid, the massive transudative pleural effusion remained largely unchanged. He underwent a repeat large volume thoracentesis on hospital day 4. The patient subsequently developed a tension pneumothorax, which resulted in a dramatic reduction in the effusion. A chest tube was placed and serial radiographs demonstrated resolution of the pneumothorax but recurrence of the effusion. The radiographs illustrate the movement of fluid between the peritoneal and pleural cavities. In this case, the mechanism of pleural effusion was confirmed to be a hepatic hydrothorax via an unintended tension pneumothorax. Methods to elucidate a hepatic hydrothorax include Tc99m or indocyanine green injection into the ascitic fluid followed by its demonstration above the diaphragm. The unintended tension pneumothorax in this case additionally demonstrates bi-directional flow across the diaphragm.

Bleeding "Dieulafoy's-like" lesion resembling the duodenal papilla: a case report.

INTRODUCTION: Dieulafoy's lesion is an uncommon but important cause of gastrointestinal bleeding in which hemorrhage occurs from a pinpoint, non-ulcerated arterial lesion. DLs are usually located in the stomach, most commonly in people between the ages of 50 and 70 years. In this report, we describe a teenage patient with an unusual presentation of a bleeding duodenal Dieulafoy's-like lesion that resembled the duodenal papilla. CASE PRESENTATION: An 18-year-old Pakistani woman presented to our emergency department with hematemesis of 6 hours' duration. Her past medical history was unremarkable. A nasogastric aspirate was negative for blood. The patient's hemoglobin was found to be 4 g/dl. She was resuscitated with intravenous fluids and blood transfusion. An esophagogastroduodenoscopy was performed, which revealed swelling in the first part of the duodenum, the initial appearance of which suggested that it was an abnormally placed or accessory papilla. There was a small, <3-mm opening on the lesion that resembled the biliary or pancreatic orifice. On gentle manipulation with a catheter, blood spurted from the swelling area, and a vessel was visible. Adrenaline was used for hemostasis. After hemostasis was achieved, it became clear that the lesion was most consistent with a Dieulafoy's-like lesion and not a papilla. Band ligation was then performed, and the patient did not develop any complications and did not have any further episodes of bleeding. The patient was eventually discharged to home in stable condition. CONCLUSIONS: This case report highlights the importance of considering a DL as a cause of small-bowel hemorrhage and recognizing its potential resemblance to the papilla. Although the endoscopic diagnostic criteria for a Dieulafoy's lesion have been described in great detail, there is a paucity of literature describing a Dieulafoy's lesion or a similar lesion resembling the duodenal papilla.

Inpatient venous access practices: PICC culture and the kidney patient.

PURPOSE: Depleted venous access is frequently cited as a reason for low fistula achievement. These quality assurance studies were designed to clarify the interactions between kidney disease, acuity of care and vascular access practices, and define the impact of nephrology intervention. METHODS: The inpatient population at an urban teaching hospital was surveyed three times between May 2010 and May 2012. Data were collected on limb protection and vascular access practices, as well as level of kidney function and level of care. RESULTS: Peripherally inserted central catheter (PICC) insertion consistently exceeded 30% in patients with chronic kidney disease; reasons for insertion were often poorly defined. More than 50% of patients had devices in the nondominant arm; use of limb protection bracelets was rare. An educational intervention designed to increase nephrologist awareness increased limb protection slightly, but did not affect the distribution of vascular access devices. CONCLUSIONS: PICC placement and invasion of the nondominant arm are both frequent in patients with abnormal kidney function, in spite of guidelines discouraging their use. The rate of PICC is higher than that of patients with normal kidney function. Current vascular access practices have substantial potential to affect future fistula rates. Effective vein protection may require participation of the entire medical community.

Characteristics and associated features of persistent post-sympathectomy pain.

OBJECTIVES: The aim of this study is to describe the incidence and characteristics of pain, sensory abnormalities, abnormal body sweating, and pathologic gustatory sweating in pain patients with persistent post-sympathectomy pain. METHODS: A retrospective chart review of a series of consecutive pain patients with persistent post-sympathectomy pain was performed. Inclusion criteria were: (1) sympathectomy performed for the indication of neuropathic pain, and (2) persistent pain after the procedure. Demographic data, patterns of pain before and after sympathectomy, patients' pain drawings, and incidence of pain had been collected concurrently at the time of referral. Additional data regarding sensory findings, surgical details of the sympathectomy, sweat patterns, and incidence of abnormal body sweating and pathologic gustatory sweating were extracted from the patients' charts or obtained in follow-up appointments. RESULTS: Seventeen adults (13 females and 4 males) with a mean age of 37 years (range 25-52) at the time of sympathectomy met the inclusion criteria. Five of the 17 patients experienced temporary pain relief for an average of 4 months (range 2-12 months), 3/17 retained the same pain as before the surgery, 1 patient was cured of her original pain but experienced a new debilitating pain, and 8/17 patients continued to have the same or worse pain in addition to a new or expanded pain. Pathologic gustatory sweating was present in 7/11 patients asked, and abnormal sweating (known as compensatory hyperhidrosis) in 11/13 patients asked. DISCUSSION: The present study does not allow for conclusions about the effectiveness of surgical sympathectomy for neuropathic pain. However, our findings indicate that if the pain persists after the procedure, the complications may be quite serious and at times worse than the problem for which the surgery was originally performed.
