Difficulty in the Clinical Diagnosis of Tularemia: Highlighting the Importance of a Physical Exam

We report an 18-month-old male who presented with fever and nonspecific symptoms. He was evaluated for multiple differential diagnoses including Kawasaki disease and JIA and received treatment for them. After he was readmitted, tularemia was considered based on the physical exam finding of an ulcer on the scalp and enlarged lymph nodes. Tularemia titers were positive, and the patient was given the appropriate antibiotic and was discharged home. Follow-up of the patient showed complete resolution of symptoms. This is a case that demonstrates the importance of physical exam in identifying rare diseases presenting with common signs and symptoms.

Inflammatory Markers in Serum and Cerebrospinal Fluid for Early Detection of External Ventricular Drain–associated Ventriculitis in Patients With Subarachnoid Hemorrhage

Background: External ventricular drain (EVD)-associated ventriculitis is a serious complication. Early diagnosis can be difficult particularly in critically ill patients with aneurysmal subarachnoid hemorrhage (aSAH). We examined the diagnostic potential of standard serum and cerebrospinal fluid (CSF) biomarkers to differentiate between EVD-associated infections and aseptic courses in patients with aSAH. Materials and Methods: We retrospectively evaluated the levels of inflammatory markers in serum (white blood cell count, percentage of neutrophils [sN%], and procalcitonin) and CSF (total leukocyte count [CSFTLC], CSFglucose, CSF/serumglucose ratio, CSF total protein [CSFTP]) of 63 consecutive patients with aSAH. Receiver operating characteristic curves and the area-under-the-curve (AUC) were calculated to detect the diagnostic potential, optimized threshold, sensitivity (SE), specificity (SP), + likelihood ratio (LR), and −LR of each biomarker. Results: Of all patients, 17 (27%) developed an EVD-associated ventriculitis within a mean of 7.8±2.3 days after implantation. sN% had a very good diagnostic potential (AUC=0.900, SE=70.0%, SP=100%), followed by the CSFTLC with good diagnostic potential (AUC=0.841, SE=75.0%, SP=88.5%), and the CSFTP with moderate diagnostic potential (AUC=0.772, SE=73.3%, SP=76.0%). sN% higher than 70% and a CSFTLC higher than 635/µL were highly associated with the diagnosis of ventriculitis (+LR=∞ and 6.5), sN%

Use of topical therapies for pediatric psoriasis: A systematic review

Abstract

Psoriasis is one of the most common chronic skin diseases, affecting 1%-3% of the general population. It can have a significant negative impact on a patient's quality of life, and in approximately 30% of patients first symptoms can be traced back to childhood. We have performed a comprehensive literature search using the MEDLINE database in order to ascertain the efficacy and adverse reactions of topical treatments in pediatric psoriasis. A total of 13 relevant articles were identified on the following topical agents: corticosteroids, calcineurin inhibitors, vitamin D analogs, and dithranol. Corticosteroids achieved clearance in 72.7% of patients. Calcitriol lead to a 57.2%-100% mean improvement in severity, and calcipotriol to 52%-64%. Combination of calcipotriol and corticosteroids achieved an improvement in mean severity ranging between 32.1% and 80%. Treatment with tacrolimus lead to an >50% improvement. Finally, short contact dithranol lead to a variable response in clearance between different studies, ranging between 3.7% and 81%. No serious adverse reactions were documented, the most common local reaction being irritation. Pediatric psoriasis is a common and challenging condition with no easy and definitive solution. Topical agents are safe, easy to use, readily available and cheap. However, they need to be applied repeatedly, may cause skin irritation, and can be messy. Based on the results presented above, we recommend utilizing all the available topical options before escalating to systemic treatments.

Phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA)-related overgrowth spectrum: A brief report

Abstract

A patient with extensive multisystem overgrowth caused by a somatic gain of function PIK3CA-mutation is described. This case is an example of the clinical diversity of the PIK3CA-Related Overgrowth Spectrum (PROS) as the patient had overlapping features of Congenital Lipomatous Overgrowth Vascular malformations Epidermal nevi and Skeletal abnormalities (CLOVES) syndrome and Megalencephaly-Capillary malformation Polymicrogyria (MCAP) syndrome and underlines the utility of this umbrella term.
