Proposal for a New Score: Hemorrhoidal Bleeding Score
Nadia Fathallah,Hélène Beaussier,Gilles Chatellier,Jean Meyer,Marc Sapoval,Nadia Moussa,Vincent de Parades 대한대장항문학회 2021 Annals of Coloproctolgy Vol.37 No.5
Purpose: We conducted a prospective study to evaluate a new hemorrhoidal bleeding score (HBS).Methods: All consecutive patients who had consulted between May 1, 2016 and June 30, 2017 for bleeding hemorrhoidal disease were prospectively assessed at a proctological department. The study was conducted in 2 stages. The first stage assessed the validity of the score on a prospective patient cohort. A second stage assessed the interobserver reproducibility of the score on another prospective cohort.Results: One hundred consecutive patients were studied (57 males; mean age, 49.70 years). A positive association between HBS and surgery indication was found (P<0.001). A cut-off value of the score of 5 (≤5 vs. >5) separated patients from surgical to medical-instrumental treatment with a sensitivity and specificity of 75.00% and 81.25%, respectively. In the multivariate analysis, only HBS was significantly associated with the operative decision (odds ratio, 12.22). Prolapse was no longer significantly associated with the surgical indication. After a mean follow-up after treatment of 7 months, HBS improved statistically significantly (P<0.0001). For the reproducibility of the score, an additional 30 consecutive patients (13 males; mean age, 53.14 years) were enrolled with an excellent agreement between 2 proctologists (kappa=0.983).Conclusion: HBS is sensitive, specific, and reproducible. It can assess the severity of hemorrhoidal bleeding. It can discriminate between the most severe surgery-indicated patients and does so in a more efficient way than the Goligher prolapse score. It also allows quantifying the extent of change in hemorrhoidal bleeding after treatment.

Rapid Clinical Bacteriology and Its Future Impact
Alex van Belkum,Géraldine Durand,Michel Peyret,Sonia Chatellier,Gilles Zambardi,Jacques Schrenzel,Dee Shortridge,Anette Engelhardt,William Michael Dunne Jr 대한진단검사의학회 2013 Annals of Laboratory Medicine Vol.33 No.1
Clinical microbiology has always been a slowly evolving and conservative science. The sub-field of bacteriology has been and still is dominated for over a century by culturebased technologies. The integration of serological and molecular methodologies during the seventies and eighties of the previous century took place relatively slowly and in a cumbersome fashion. When nucleic acid amplification technologies became available in the early nineties, the predicted “revolution” was again slow but in the end a real paradigm shift did take place. Several of the culture-based technologies were successfully replaced by tests aimed at nucleic acid detection. More recently a second revolution occurred. Mass spectrometry was introduced and broadly accepted as a new diagnostic gold standard for microbial species identification. Apparently, the diagnostic landscape is changing, albeit slowly, and the combination of newly identified infectious etiologies and the availability of innovative technologies has now opened new avenues for modernizing clinical microbiology. However, the improvement of microbial antibiotic susceptibility testing is still lagging behind. In this review we aim to sketch the most recent developments in laboratory-based clinical bacteriology and to provide an overview of emerging novel diagnostic approaches.

Objective This study evaluated the impact of head computed tomography (CT) on clinical decision-making about older adults with acute altered mental status (AMS) in the emergency department in terms of CT’s diagnostic yield, emergency department length of stay, and changes in medical strategy. It also attempted to find predictors of an acute imaging abnormality.Methods This was a 1-year, retrospective, single-center observational study of patients aged ≥75 years who underwent noncontrast head CT because of an isolated episode of AMS. The acute positive CT findings were ischemic strokes, hemorrhages, tumors, demyelinating lesions, hydrocephalus, and intracranial infections.Results A total of 594 CTs were performed, of which 38 (6.4%) were positive. The main etiology of AMS was sepsis (29.1%). Changes in medical strategy were more common in patients with a positive CT, and the major changes were ordering additional neuro exams (odds ratio [OR], 95.3; 95% confidence interval [CI], 38.4–233.8; P<0.001), adjusting treatments (OR, 12.2; 95% CI, 5.0–29.5; P<0.001), and referral to a neurologic unit (OR, 7.3; 95% CI, 3.0–17.5; P<0.01). Three factors were significantly associated with a positive outcome: Glasgow Coma Scale <13 (OR, 8.5; 95% CI, 2.3–28.9; P<0.001), head wound (OR, 3.1; 95% CI, 1.1–8.2; P=0.025), and dehydration (OR, 0.3; 95% CI, 0.1–0.4; P=0.021). For elderly patients with a Glasgow Coma Scale ≥13 and no head wound or clinical dehydration, the probability of a positive CT was 0.02 (95% CI, 0.01–0.04). Considering only those patients, the diagnostic yield fell to 1.7%.Conclusion In elderly patients, the causes of AMS are primarily extracerebral. Randomized clinical trials are needed to validate a clinical pathway for selecting patients who require emergent neuroimaging.
