Fever of Multiple Possible Origins
Authors: Spillane David , Wiseman Jeffrey
Published: June 2021

A 60-year-old man presented with 1 week of fever despite broad-spectrum antibiotics for presumed pyelonephritis based on extended spectrum bacteriuria, recent bladder catheterization, and a negative search for other infections. He developed a maculopapular truncal rash, and pancytopenia with persistent fevers and worsening inflammatory markers despite modifying then stopping antibiotics. The non-specific clinical features at presentation and absence of hemophagocytosis on the initial bone marrow aspirate confounded multiple subspecialists and delayed the final diagnosis of hemophagocytic lymphohistiocytosis (HLH). Once this syndrome was elucidated, he responded well to dexamethasone and etoposide. An underlying diagnosis of systemic lupus erythematosus with aortic vasculitis was made, which in combination with pyelonephritis likely precipitated HLH. We summarize current concepts, pitfalls, and lessons learned in the diagnosis and management of HLH.
RésuméUn homme de 60 ans se présente à l’hôpital à la suite d’une semaine de fièvre malgré la prise d’antibiotiques à large spectre pour traiter une pyélonéphrite soupçonnée, fondée sur une bactériurie à spectre étendu, un cathétérisme vésical récent et une recherche infructueuse d’autres infections. Il a développé une éruption cutanée maculopapulaire sur le tronc et une pancytopénie accompagnée d’une fièvre persistante et d’une augmentation des marqueurs de l’inflammation malgré la modification, puis l’arrêt des antibiotiques. Les manifestations cliniques non spécifiques à la présentation et l’absence d’hémophagocytose lors de la ponction médullaire initiale ont confondu de multiples surspécialistes et retardé le diagnostic définitif de lymphohistiocytose hémophagocytaire (LHH). Une fois que ce syndrome a été élucidé, le patient a bien répondu au traitement par la dexaméthasone et l’étoposide. Un diagnostic sous-jacent de lupus érythémateux systémique accompagné d’une vascularite de l’aorte a été posé qui, combiné à la pyélonéphrite, a probablement précipité la LHH. Nous résumons les concepts actuels, les pièges et les leçons apprises dans le diagnostic et la prise en charge de la LHH.

BackgroundPoint-of-care lung ultrasound (LUS) examination is increasingly utilized in Internal Medicine. To improve the standardization of LUS education and clinical use, explicit minimal criteria for defining what is an acceptable and clinically useful image are needed.MethodsA 97-item online survey of potential minimal criteria for common uses of LUS in Internal Medicine was developed and sent to 10 international point-of-care ultrasound experts. Their opinion on the inclusion of each item was sought and items not achieving consensus (defined as agreement by at least 70% of the experts) were reassessed in subsequent rounds. A total of three rounds were conducted.ResultsSeventy-four minimal criteria were agreed upon for inclusion, 24 were agreed upon for exclusion, and two did not reach consensus.ConclusionsExperts agreed on 74 minimal criteria for Internal Medicine LUS. The use of these minimal criteria during teaching and clinical use is strongly recommended.

Published: June 2021

Objectives: To study the incidence of rhabdomyolysis (RML) after
ascending aortic dissection surgery and to correlate with the outcome
especially in terms of renal function. The secondary objective was to
pinpoint the perioperative risk factors associated with the development
of Rhabdomyolysis and adverse renal outcome after Aortic dissection
repair Design: Retrospective single-center study Settings: Tertiary
cardiac center Participants: Patients who had undergone ascending aortic
dissection repair from 2011-2017. Interventions: Two groups Group 1-
with RML creatine kinase (CK) above cut-off levels 2500 U/Liter and
Group 2 without RML. The potential determinants of RML and the impact of
the same on the patient outcome; especially on postoperative renal
function was studied. Measurements and main results: Out of 33 patients
studied, 21 patients (64%) developed Rhabdomyolysis (Group RML) and 12
did not (Group non-RML). Demographic and intraoperative factors had no
significant impact on the incidence of RML. There was a significantly
higher incidence of AKI in the RML group (90%) than in the non-RML
group (25%). All 4 patients who went into new post-operative dialysis
belonged to the RML group. The peak troponin levels were significantly
higher in RML group Conclusion: In this study, we found a high incidence
of RML after aortic dissection surgery which paralleled with an adverse
renal outcome and need for postoperative dialysis. Identification of
risk factors and early intervention might help to mitigate the severity
of renal failure. Further large-scale prospective trials are warranted
to investigate the predisposing factors and influence of RML on outcome

Published: June 2021

Introduction. In the world with constantly increasing incidence of violence and trauma on one side, and more and more specialized surgeons on the other, the question about the role of abdominal surgeons in cardiac trauma emerges. The objective of this article is to show personal experience of an abdominal surgeon in managing heart trauma. Outlines of cases. We present two penetrating injuries and one blunt trauma of the heart successfully managed by an abdominal surgeon. Conclusion. Abdominal surgeons should feel comfortable with the decision to operate on greatly physiologically deranged patients with penetrating chest trauma, and not to delay the operation with conservative measures or with time-consuming transport to remote specialized facilities, since that could lead to greater death percentage of these patients.

Published: June 2021

Objective:

The purpose of this study was to evaluate the influence of different illuminants on the perceptibility and acceptability of surface gloss variations and to determine limiting values.

Methods:

Eight composite resin specimens and one human tooth specimen were polished to obtain composite resin specimens with different gloss units (GU) of 10, 20, 30, 40, 50, 60, 70, and 80 and a human tooth specimen of 80 GU. Sixty observers compared the surface gloss of the specimens in a light booth. For perceptibility testing, the specimens were randomly positioned two at a time. The acceptability of the gloss variation was determined by comparing the composite resin specimens with the tooth specimen. The observers answered specific questions to determine the level and perceptibility and acceptability limits of gloss variations. All analysis was done with two illuminants (D65 and fluorescent light) used randomly. Data were submitted to a nonlinear probit model and nonlinear probit regression estimation (α=0.05).

Results:

Significant differences in illuminants were observed for perceptibility (p<0.001) and acceptability (p=0.045). The perceptibility limit for D65 was 7.0 GU and 6.8 GU for fluorescent illuminant. The acceptability limit for D65 was 34.2 GU and 37.1 GU for fluorescent illuminant.

Conclusions:

More accurate perceptibility and acceptability judgments of the surface gloss of composite resin were made when the specimens were illuminated with D65 light.
