Fluid Overload and Renal Angina Index at Admission Are Associated With Worse Outcomes in Critically Ill Children.

Objectives: We investigated the association of fluid overload and oxygenation in critically sick children, and their correlation with various outcomes (duration of ventilation, ICU stay, and mortality). We also assessed whether renal angina index (RAI) at admission can predict mortality or acute kidney injury (AKI) on day 3 after admission. Design and setting: Prospective study, pediatric intensive care in a tertiary hospital. Duration: June 2013-June 2014. Patients: Patients were included if they needed invasive mechanical ventilation for >24 h and had an indwelling arterial catheter. Patients with congenital heart disease or those who received renal replacement therapy (RRT) were excluded. Methods: Oxygenation index, fluid overload percent (daily, cumulative), RAI at admission and pediatric logistic organ dysfunction (PELOD) score were obtained in all critically ill children. KDIGO classification was used to define AKI, using both creatinine and urine output criteria. Admission data for determination of RAI included the use of vasopressors, invasive mechanical ventilation, percent fluid overload, and change in kidney function (estimated creatinine clearance). Univariable and multivariable approaches were used to assess the relations between fluid overload, oxygenation index and clinical outcomes. An RAI cutoff >8 was used to predict AKI on day 3 of admission and mortality. Results: One hundred and two patients were recruited. Fluid overload predicted oxygenation index in all patients, independent of age, gender and PELOD score (p < 0.05). Fluid overload was associated with longer duration of ventilation (p < 0.05), controlled for age, gender, and PELOD score. Day-3 AKI rates were higher in patients with a RAI of 8 or more, and higher areas under the RAI curve had better prediction rates for Day-3 AKI. An RAI <8 had high negative predictive values (80-95%) for Day-3 AKI. RAI was better than traditional markers of pediatric severity of illness (PELOD) score for prediction of AKI on day 3. Conclusions: This study emphasizes that positive fluid balance adversely affects intensive care in critically ill children. Further, the RAI prediction model may help optimize treatment and improve clinical prediction of AKI.

Primary Pancreatic Burkitt's Lymphoma: A Case Report and Review of the Literature.

Primary pancreatic lymphoma (PPL) is of very rare occurrence as an extra nodal site of Non-Hodgkin's lymphoma (NHL). It represents less than 1% of NHL. Out of which Burkitt lymphoma of pancreas is of a rare presentation. It usually occurs in children and presenting in adults is uncommon. The prevalence of pancreatic Burkitt lymphoma is not known as the incidence is significantly low. Clinical features of PPL are predominantly nonspecific and can become difficult with associated inflammation of pancreas. Differentiation of lymphoma to adenocarcinoma is important as chemotherapy is the main stay of treatment in lymphoma. We report a case of 68-year-old female who presented with nonspecific symptoms and was found to have obstructive jaundice secondary to pancreatic head neoplasm which was proved to be pancreatic Burkitt lymphoma which is a rare presentation.

Disseminated mycobacterium avium complex as protein-losing enteropathy in a non-HIV patient.

Disseminated mycobacterium avium complex (MAC) causing protein-losing enteropathy (PLE) due to intestinal lymphangiectasia (IL) in a non-HIV immunocompromised state is extremely rare. We present a case of 56-year-old male who was evaluated for worsening dyspnea and found to have right-sided chylous pleural effusion as well as worsening abdominal and retroperitoneal lymphadenopathy. He had a history of psoriasis for which hewas on etanercept and alefacept which were stopped two years prior to the presentation. The evaluation revealed a MAC infection in his lymph nodes--a low CD4 count but negative for HIV. He was started on MAC therapy. He subsequently developed noninfectious diarrhea, Hypoalbuminemia, recurrentpleural effusions, ascites, and Pneumocystis jiroveci pneumonia (PJP). Despite appropriate antibiotics and management--including total parental nutrition (TPN) with a medium-chain triglyceride enriched low fat diet--the patient's clinical condition deteriorated rapidly resulting in death.

An unusual case of fever of unknown origin.

Mycobacterium avium complex (MAC) infection is a common complication of the later stages of AIDS. Extrapulmonary infection with MAC in HIV-negative patients is considered uncommon. We report a case of a young female who presented with fever of unknown origin on multiple occasions and failed to be diagnosed with MAC by acid-fast stain initially. Subsequently, the patient presented with pancytopenia due to bone marrow biopsy-proven infection with MAC. The patient was not on any immunosuppressant regimen.
