RESUMO
PURPOSE: Improving the safety of general wards is a key to reducing serious adverse events in the postoperative period. We investigated the characteristics, treatment, and outcomes of postoperative patients managed by a rapid response system (RRS) in Japan to improve postoperative management. METHODS: This retrospective study analyzed cases requiring RRS intervention that were included in the In-Hospital Emergency Registry in Japan. We analyzed data reported by 34 Japanese hospitals between January 2014 and March 2018, mainly focusing on postoperative patients for whom the RRS was activated within 7 days of surgery. Non-postoperative patients, for whom the RRS was activated in all other settings, were used for comparison as necessary. RESULTS: There were 609 (12.7%) postoperative patients among the total patients in the registry. The major criteria were staff concerns (30.2%) and low oxygen saturation (29.7%). Hypotension, tachycardia, and inability to contact physicians were observed as triggers significantly more frequently in postoperative patients when compared with non-postoperative patients. Among RRS activations within 7 days of surgery, 68.9% of activations occurred within postoperative day 3. The ordering of tests (46.8%) and fluid bolus (34.6%) were major interventions that were performed significantly more frequently in postoperative patients when compared with non-postoperative patients. The rate of RRS activations resulting in ICU care was 32.8%. The mortality rate at 1 month was 16.2%. CONCLUSION: Approximately, 70% of the RRS activations occurred within postoperative day 3. Circulatory problems were a more frequent cause of RRS activation in the postoperative group than in the non-postoperative group.

BACKGROUND: Bacillus cereus is a gram-positive rod bacterium that is responsible for food poisoning. It is naturally widely distributed, and thus often contaminates cultures. Although it is rarely considered responsible, it can cause serious infections under certain conditions. However, lethal infections, especially in immunocompetent patients, are rare. CASE PRESENTATION: A healthy 60-year-old man developed community-acquired B. cereus pneumonia and alveolar hemorrhage unveiled by abrupt chest pain and hemoptysis with no other advance symptoms. B. cereus induced silent alveolar destruction without any local or systemic inflammatory response. Although the lesion resembled lung anthrax, there was no evidence of Bacillus anthracis toxin. CONCLUSIONS: Some isolates of B. cereus can cause anthrax-like fulminant necrotizing pneumonia in immunocompetent patients. If this type of B. cereus were used as a means of bioterrorism, it may be quite difficult to recognize as bioterrorism. We should keep B. cereus in mind as a potential pathogen of fulminant human infectious disease.

Streptococcal toxic shock syndrome is a severe infectious disease. We report a Japanese case of Streptococcal toxic shock syndrome caused by a highly mucoid strain of Streptococcus pyogenes. A 31-year old female with shock vital sign presented at a tertiary medical center. Her left breast was necrotizing and S. pyogenes was detected by Immunochromatographic rapid diagnostic kits. Intensive care, including administration of antibiotics and skin debridement, was performed. After 53 days in our hospital, she was discharged. The blood cultures and skin swab cultures all grew S. pyogenes which displayed a highly mucoid morphology on culture media. In her course of the disease, the Streptococcus strain had infected two other family members. All of the strains possessed the T1 and M1 antigens, as well as the emm1.0 gene. As for fever genes, the strains were all positive for speA, speB, and speF, but negative for speC. All of the strains exhibited and the same pattern in PFGE with the SfiI restriction enzyme. The strain might have spread in the local area by the data from the Japanese Infectious Disease Surveillance Center. Immunochromatographic rapid diagnostic kits are very useful for detecting S. pyogenes. However, they can not be used to diagnose severe streptococcul disease by highly mucoid strain alone. Careful observation of patients and colony morphology are useful methods for diagnosing severe streptococcal disease by highly mucoid strain.

We herein report a case of severe fever with thrombocytopenia syndrome (SFTS) with Pasteurella multilocida bacteremia in a 65-year-old man with alcoholic cirrhosis who was admitted to our hospital with anorexia and severe fatigue. Laboratory tests revealed pancytopenia and liver and kidney dysfunction. After admission, he developed impaired consciousness, mucosal hemorrhaging, and septic shock. SFTS virus was detected on polymerase chain reaction testing of blood and throat swabs, and Pasteurella multocida was detected on blood culture. Despite being treated with invasive mechanical ventilation, vasopressors, and antibiotics, the patient's condition progressively deteriorated, and he died four days after admission.

BACKGROUND: As the global population ages, the incidence of traumatic brain injury (TBI) is increasing. Whereas mild TBI can impair the cognitive function of older adults, the cause and background of mild TBI-induced cognitive impairment remain unclear, and the evaluation of risk factors for cognitive impairment after mild TBI remains open for consideration, especially in the aging population. This study aimed to evaluate the risks associated with cognitive impairment following mild TBI. METHODS: Between January 2006 and December 2018, a total of 2209 patients with TBI required hospitalization in Shimane Prefectural Central Hospital. Mild TBI was defined as a Japan Coma Scale ≤10 at admission. Patients' cognitive function was measured with the Hasegawa Dementia Rating Scale-Revised or Mini-Mental State Examination at least twice during the patients' hospital stays. The odds ratio (OR) and 95% confidence interval (CI) of each considered risk factor was calculated with multivariable logistic regression analysis after univariate analysis. RESULTS: Among 1674 patients with mild TBI, 172 patients underwent cognitive function examinations, of whom 145 (84.3%) were found to have cognitive impairment at discharge. Significant risk factors for cognitive impairment included age (P = 0.008) and hypertension (P = 0.013) in univariate analysis; and age (OR, 1.04: 95% CI, 1.01-1.07) and hypertension (OR, 5.81: 95% CI, 1.22-27.68) by multivariable analysis. CONCLUSIONS: Older patients with hypertension displayed a significantly higher risk for cognitive impairment after even mild TBI. These patients warrant careful management after even mild TBI.

The most common symptom following the accidental ingestion of a soap is lip edema. Although most cases are asymptomatic or exhibit mild symptoms, in some cases, aspiration pneumonia, oropharyngeal edema, and bronchial obstruction may be fatal.
RESUMO
AIM: The rapid response system (RRS) is an in-hospital medical safety system. To date, not much is known about patient disposition after RRS activation, especially discharge home. This study aimed to investigate the prevalence, characteristics, and outcomes of patients with adverse events who required RRS activation. METHODS: Retrospective data from the In-Hospital Emergency Registry in Japan collected from April 2016 to November 2020 were eligible for our analysis. We divided patients into Home Discharge, Transfer, and Death groups. The primary outcome was the prevalence of direct discharge home, and independently associated factors were determined using multivariable logistic regression. RESULTS: We enrolled 2,043 patients who met the inclusion criteria. The prevalence of discharge home was 45.7%; 934 patients were included in the Home Discharge group. Age (adjusted odds ratio [AOR] 0.96; 95% confidence interval [CI], 0.95-0.97), malignancy (AOR 0.69; 95% CI, 0.48-0.99), oxygen administration before RRS (AOR 0.49; 95% CI, 0.36-0.66), cerebral performance category score on admission (AOR 0.38; 95% CI, 0.26-0.56), do not attempt resuscitation order before RRS (AOR 0.17; 95% CI, 0.10-0.29), RRS call for respiratory failure (AOR 0.50; 95% CI, 0.34-0.72), RRS call for stroke (AOR 0.12; 95% CI, 0.03-0.37), and intubation (AOR 0.20; 95% CI, 0.12-0.34) were independently negative, and RRS call for anaphylaxis (AOR 15.3; 95% CI, 2.72-86.3) was positively associated with discharge home. CONCLUSION: Less than half of the in-hospital patients under RRS activation could discharge home. Patients' conditions before RRS activation, disorders requiring RRS activation, and intubation were factors that affected direct discharge home.
RESUMO
We report a case of rapidly progressive necrotizing soft tissue infection and sepsis followed by a patient's death. We suspected Vibrio vulnificus infection because the patient's underlying disease was cirrhosis and the course extremely rapid. No microbe had been detected at death. We extracted DNA from a blood culture bottle. SYBR green I real-time PCR was conducted but could not detect V. vulnificus vvh in the DNA sample. Aeromonas hydrophila was cultured and identified in blood and necrotized tissue samples. Real-time PCR was conducted to detect A. hydrophila ahh1, AHCYTOEN and aerA in the DNA sample extracted from the blood culture bottle and an isolated necrotized tissue strain, but only ahh1 was positive. High-mortality in necrotizing soft tissue infections makes it is crucial to quickly detect V. vulnificus and A. hydrophila. We found real-time PCR for vvh, ahh1, AHCYTOEN, and aerA useful in detecting V. vulnificus and A. hydrophila in necrotizing soft tissue infections.

BACKGROUND: Psoas abscess and pyogenic spondylitis are intractable diseases that require long-term treatment, but the clinical characteristics and causative organisms have not been fully investigated. Herein, we describe the clinical characteristics of these diseases and evaluate the factors associated with in-hospital mortality and the presence of gram-negative rods as causative microorganisms. METHODS: All patients diagnosed with pyogenic spondylitis or psoas abscesses at a tertiary hospital were included. We retrieved the clinical data (age, sex, outcome, length of hospital stay, disease, bacteria, medication, comorbidities, and treatment status), vital signs (blood pressure, heart rate, and body temperature), and laboratory test results (blood cell count, liver function, renal function, electrolytes, blood sugar, and C-reactive protein) of all patients. The outcomes were in-hospital deaths and positive cultures of gram-negative rods. RESULTS: We analyzed 126 patients consisting of 69 (55%) men with a population mean age of 72 years. Seventy-two patients had pyogenic spondylitis and 54 had psoas abscesses. Eleven patients (8.3%) died during admission. The causative bacteria were gram-positive cocci in 63 patients (50%) and gram-negative bacteria in 19 patients (15%). The multivariate logistic model showed that blood urea nitrogen (BUN) (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.02-1.06) and cardiovascular diseases (OR 7.02, 95% CI 1.55-31.8) were associated with in-hospital mortality. Platelets less than 150,000/µL (OR 3.14, 95% CI 1.02-9.65) and higher aspartic aminotransferase (OR 1.02, 95% CI 1.00-1.03) were associated with gram-negative rods. CONCLUSIONS: Patients with suspected psoas abscesses or pyogenic spondylitis having a high BUN level and a history of cardiovascular diseases have a higher risk of mortality.

BACKGROUND: Hepatic resection is prone to significant blood loss. Adverse effects of blood loss and transfusion mandate improvements in surgical techniques to reduce blood loss and transfusion. METHODS: We retrospectively analyzed the present status of intraoperative blood transfusion practice of 42 hepatic resections in National Kure Medical Center for the year of 2000. RESULTS: Median values for blood loss were 1355, 1708, 1415, and 2298 ml for nonanatomic, subsegmental, segmental and extended right resections, respectively. Crossmatched to transfused blood (C/T) ratios were 1.76, 1.19, 2.31, and 0.90 for nonanatomic, subsegmental, segmental and extended right resections, respectively. CONCLUSION: In general, C/T ratio of 1.5 to 2.5 has been recommended but own C/T ratios are 1.19 and 0.9 for subsegmental and extended right hepatic resection, which are lower than recommended values. It was estimated that inappropriate prediction of blood loss by several surgeons and unused maximum surgical blood order schedule (MSBOS) or type and screen (T&S) decreased these values of C/T ratio in the present analysis. We therefore conclude that MSBOS and T&S could be improved by avoiding such in appropriate prediction.

Pyogenic liver abscess caused by Klebsiella pneumoniae is an emerging disease worldwide, and we know the serotype K1 strain to be the most virulent strain. We report a Japanese case of septic pyogenic liver abscess caused by K. pneumoniae genetic serotype K1. A 60-year old man presented at our hospital in a state of cardiopulmonary arrest. From the patient's chief complaint of chest pain, we suspected acute coronary syndrome, i.e., acute myocardial infarction. We used extracorporeal circulation and checked coronary angiography, but the 75% stenosis by itself could not adequately account for the patient's critical condition. The patient's laboratory data indicated multiple organ failure. The patient's condition did not improve while in intensive care and he died 20 h after the onset of the cardiopulmonary arrest. Pathological autopsy later showed colliquative necrosis in the deltoid and left greater pectoral muscles, as well as liver abscesses. The patient's blood, gastric juice, and stool cultures all grew a Gram-negative bacillus identified as Klebsiella pneumoniae. We also performed capsular polysaccharide synthesis (cps) genotyping by polymerase chain reaction for the detection of K serotype-specific alleles at the wzx and wzy loci. The result indicated that wzx_K1 and wzy_K1 were positive. This is the first reported Japanese case of septic pyogenic liver abscess caused by K. pneumoniae genetic serotype K1.
