RESUMO
Corynebacterium ulcerans is a closely related bacterium to the diphtheria bacterium C. diphtheriae, and some C. ulcerans strains produce toxins that are similar to diphtheria toxin. C. ulcerans is widely distributed in the environment and is considered one of the most harmful pathogens to livestock and wildlife. Infection with C. ulcerans can cause respiratory or nonrespiratory symptoms in patients. Recently, the microorganism has been increasingly recognized as an emerging zoonotic agent of diphtheria-like illness in Japan. To clarify the overall clinical characteristics, treatment-related factors, and outcomes of C. ulcerans infection, we analyzed 34 cases of C. ulcerans that occurred in Japan during 2001-2020. During 2010-2020, the incidence rate of C. ulcerans infection increased markedly, and the overall mortality rate was 5.9%. It is recommended that adults be vaccinated with diphtheria toxoid vaccine to prevent the spread of this infection.

In Japan, reports on the association of individual characteristics, and geographical distance and time with clinical outcomes for neurological emergencies involving helicopter emergency medical services (HEMS) are scarce. Using Tochigi HEMS data (2010-2018), we assessed the characteristics of 1,170 emergency neurological patients (e.g., stroke, neurotrauma, and seizure) at the base hospital, which covered 58% of all HEMS patients in the prefecture. After initial treatment in the emergency room, emergency physicians confirmed the clinical outcomes of each patient compared to those at the incident sites (recovery/non-recovery). We calculated the geographic distance from the base hospital to each incident site, and estimated and adjusted odds ratios (aOR) and 95% confidence intervals (CI) for non-recovery against distance. The mean distance between the incident site and base hospital was 22.0 ± 11.7 km, and 77.4% of patients recovered following initial treatment. Two peak age groups were observed among emergency neurological diseases, including seizures in patients who were aged < 5 years and stroke and neurotrauma in patients who were aged 70-80 years. The percentages of stroke, traumatic head and brain injury, and seizure were 35.8%, 29.2%, and 22.8%, respectively. The incidence of stroke (aOR = 11.8, 95% CI 6.86-20.3) and neurotrauma (aOR = 4.86, 95% CI 2.78-8.51) independently predicted a poor prognosis. However, no significant association was observed with the distance from the base hospital. Therefore, in the Tochigi prefecture, geographical disparities may not affect the short-term prognosis of patients with neurological emergencies who were transported by HEMS.

A 69-year-old female was introduced to our department for a retroperitoneal mass, 25 mm in diameter, in the right perirenal space indicated by computed tomography (CT). On the basis of magnetic resonance imaging (MRI), retroperitoneal soft tissue sarcoma was suspected. Because she rejected surgical treatment, we continued imaging surveillance. Subsequently, the mass grew larger, but her intention did not change. At 21 months after initial consultation, CT revealed further increase of the above mass and a new lesion with calcification. Ultimately, she underwent mass resection with concomitant resection of the right kidney. Histological examination showed dedifferentiated liposarcoma with metaplastic bone formation and positive surgical margin, but she refused adjuvant chemotherapy. She has survived 7 months since the operation with no evidence of recurrence.

A 76-year-old man was introduced to our department with a right kidney stone. On the basis of further examination, he was diagnosed with a 23 mm right kidney stone accompanied with a horseshoe kidney. Retrograde pyelography and diuretic renogram revealed a non-obstructed right ureteropelvic junction. Finally, we chose laparoscopic pyelolithotomy via peritoneal approach because the stone was large and accompanied with a horseshoe kidney. The surgery took 165 minutes and the estimated blood loss was 25 ml. There were no minor or major complications. Because horseshoe kidney has anatomical abnormalities, it seems to be necessary to consider a different treatment strategy from that of an upper urinary tract stone in a healthy kidney. We assume that laparoscopic pyelolithotomy is an effective and safe procedure for renal pelvic stones in the case of a horseshoe kidney.

A 92-year-old man had noticed enlargement of a mass in the right scrotum and inguinal region for nine months. The patient was introduced to our department for right testicular tumor. Physical examination showed an over fist-sized, hard mass in the right scrotum. Magnetic resonance imaging (MRI) showed the mass, which consisted of fatty and solid contents. In addition, MRI revealed a bladder tumor simultaneously. Computed tomography revealed no distant metastases. The patient underwent right high orchiectomy with the mass resection and transurethral resection of the bladder tumor (TURBT). Pathological examination revealed well- and dedifferentiated liposarcoma of the right spermatic cord, and urothelial cancer of the bladder. Liposarcoma of the spermatic cord is a rare neoplasm. To the best of our knowledge, the present case was the 114 th reported case and oldest in Japan.

Triflumizole (TFZ) is a fungicide widely used in agriculture to prevent fungal infections of fruits and vegetables. Although it is considered safe for humans and animals, its toxicity profile in humans remains largely unexplored. Here, we describe a case where an individual experienced symptoms suggestive of intoxication after ingesting TFZ emulsion. A 70-year-old man ingested TFZ emulsion (Trifumin emulsionTM) and alcohol in an attempt to commit suicide. He developed a severe disturbance of consciousness, which was not explained by the estimated blood alcohol concentration, and experienced convulsions. We managed this patient with symptomatic treatment, temporary mechanical ventilation, and antiepileptic drugs. He subsequently recovered without any sequelae. We present the first case of acute oral intoxication with TFZ emulsion. Moreover, we review the literature on TFZ-induced organ dysfunction and discuss the possible mechanisms and management of this condition.
RESUMO
Background/Objectives: The impacts of the coronavirus disease 2019 (COVID-19) pandemic on patients using helicopter emergency medical services (HEMS) regarding tracheal intubation and patient management remain unclear. Thus, we aimed to investigate this matter in Japan. Methods: In this retrospective, observational study, we analyzed 2277 patients who utilized HEMS in Tochigi Prefecture during 2018-2022. We included only patients who required tracheal intubation. We categorized patients from February 2020 to January 2022 in the pandemic group and those from February 2018 to January 2020 in the control group. We compared the interval from arrival at the scene to leaving the scene (on-scene time) and secondary variables between the two groups. Results: A total of 278 eligible patients were divided into the pandemic group (n = 127) and the control group (n = 151). The on-scene time was lower during the pandemic than that before (25.64 ± 9.19 vs. 27.83 ± 8.74 min, p = 0.043). The percentage of patients using midazolam was lower (11.8% vs. 22.5%, p = 0.02) and that of patients using rocuronium bromide was higher (29.1% vs. 6.0%, p < 0.001) during the pandemic. In contrast, the type of intervention other than tracheal intubation and the type of transportation to the hospital did not differ between the groups. Conclusions: The COVID-19 pandemic was associated with changes in the mission time of and the frequency of certain drugs administered by the HEMS. However, the type of intervention and the type of transportation did not differ. Further research is needed on changes in patient prognosis and condition due to the effects of the COVID-19 pandemic.
RESUMO
In adult intensive care, brain hypothermia therapy (BHT) was reported to be effective in neuroprotection after resuscitation and cardiac arrest. By contrast, in neonatal intensive care, the pathophysiology of brain damage caused by hypoxic-ischemic encephalopathy (HIE) is attributed to circulatory disturbances resulting from ischemia/reperfusion, for which neonatal brain cryotherapy is used. The International Liaison Committee on Resuscitation, 2010, recommends cerebral cryotherapy for HIE associated with severe neonatal pseudoparenchyma death. The usefulness of BHT for neuroprotection in infants and children, especially in pediatric acute encephalopathy, is expected. Theoretically, BHT could be useful in basic medical science and animal experiments. However, there are limitations in clinical planning for treating pediatric acute encephalopathy. No international collaborative study has been conducted, and no clinical evidence exists for neuroprotection using BHT. In this review, we will discuss the pathogenesis of neuronal damage in hypoxic and hypoperfused brains; the history of BHT, its effects, and mechanisms of action; the success of BHT; cooling and monitoring methods of BHT; adverse reactions to BHT; literature on BHT. We will review the latest literature on targeted temperature management, which is used for maintaining and controlling body temperature in adults in intensive care. Finally, we will discuss the development of BHT and targeted temperature management as treatments for pediatric acute encephalopathy.
RESUMO
BACKGROUND: Big cat bites are highly lethal due to the enormous bite force of these animals. This article reviews the morphology of these types of injuries and key points of management through a survival case at a Japanese safari park. CASE PRESENTATION: We report the case of a 26-year-old female keeper who was attacked by a tiger. She was quickly transported to our university hospital by ambulance helicopter. The keeper was severely bitten on the head and face and had wounds all over her body. Craniofacial repair was performed by emergency surgery. She suffered mild facial nerve paralysis and trismus because of being bitten by the tiger and is currently recovering. CONCLUSIONS: A multidisciplinary approach of the severe tiger bites successfully treated a young woman cosmetically and mentally. Animal farms and zoos that keep tigers should take strict measures to avoid direct confrontation with tigers.
RESUMO
Management of abdominal compartment syndrome (ACS) due to renal injury is important. A 21-year-old man was taken to an emergent care unit with grade IV right kidney trauma and hypovolemic shock due to a road traffic injury. Despite twice targeted transcatheter arterial embolization of a renal artery, intravesical pressure increased and blood pressure was difficult to maintain. After right nephrectomy and ligated the bleeding lumbar arteries and veins to avoid ACS, the patient's general condition improved, and he did not develop ACS. Monitoring of intravesical pressure may be useful for deciding treatment strategy.
RESUMO
BACKGROUND: Helicopter Emergency Medical Services (HEMS) has been in operation in Japan since 2001, allowing patients almost anywhere in the nation to receive on-scene emergency treatment from physicians. However, there is insufficient literature on the characteristics of the patients who use Japanese HEMS. Thus, this study aimed to investigate the overall characteristics of patients receiving HEMS care within a single prefecture in Japan. METHODS: We retrospectively analyzed the data of 5163 patients-in Tochigi Prefecture-who received HEMS care from 2012 to 2019. Descriptive statistics were used to analyze the following aspects of care: diagnosis, severity, background characteristics, geographical and environmental variables, immediate pre-hospital intervention, transportation type, and short-term clinical outcomes. RESULTS: Among 7370 HEMS requests received during the study period, treatment was provided to 5163 patients (1.8 cases per day; 3489 men [67.6%]). Nearly 55% (n = 2856) of patients were aged above 60 years. Age peaks were observed at 0-9 years and 60-69 years. The median distance from the base hospital to the site was 26.7 km. The age-standardized rate of HEMS treatment was 30.3 patients per 100,000 people. Cases of trauma and cardiovascular diseases were the most common (65.3%). Most individuals aged 0-9 years and 60-69 years had neurological disease (seizures accounted for 80.5% of this group) and cardiovascular disease, respectively. The number of patients was similar across all four seasons. After immediate pre-hospital intervention, 81.6% of patients receiving HEMS care were transferred by the helicopter ambulance (53.4% and 28.2% to the base hospital and to other hospitals, respectively). Overall, 56.6% of patients receiving HEMS care were transferred to the base hospital, and the short-term recovery rate was above 75%. Intravenous drip and oxygen administration were the most common pre-hospital interventions (93.1% and 72.7%, respectively). CONCLUSIONS: This study is the first to describe the overall characteristics of HEMS patients using comprehensive data of all HEMS patients in one prefecture in Japan. Further research using both local- and national-level data is needed to accelerate the understanding of the benefits of HEMS.

BACKGROUND: Infections caused by Corynebacterium ulcerans, a zoonotic pathogen, have been reported worldwide. This microorganism is known to produce the diphtheria toxin and cause diphtheria-like illness. CASE PRESENTATION: A 63-year-old woman with a history of diabetes and hypertension developed cold and flu-like symptoms, which gradually progressed into respiratory distress. Therefore, the patient was intubated for dyspnea with pseudomembrane formation. A toxin-producing strain of C. ulcerans was identified, also detected in the patient's domestic cats. Multilocus sequence typing confirmed all strains, including the patient's isolate, as ST337. CONCLUSION: Multilocus sequence typing revealed zoonotic transmission of C. ulcerans from domestic cats to a human.
RESUMO
Childhood Guillain-Barré syndrome (GBS) occasionally leads to respiratory failure early after onset, requiring long-term ventilation management after tracheal intubation. However, patients requiring tracheostomy management are rare. In the present study, a case of a 12-year-old boy with GBS who required artificial respiration management due to rapid progression of respiratory muscle paralysis is reported. Intravenous immunoglobulin (IVIg) and pulse steroid therapy were provided; however, both were ineffective and tracheostomy was necessary 26 days after onset. A second course of IVIg and pulse steroid therapy was administered on day 34. With continued rehabilitation, the patient was able to walk long distances on day 74 and was subsequently discharged on day 89. In cases of severe GBS, when IVIg and pulse steroid therapy do not improve the respiratory muscle strength of the patient, early tracheostomy may improve the patient's quality of life during artificial respiration management.
RESUMO
OBJECTIVE: To investigate the longitudinal alteration of health-related quality of life (HRQL) up to 5 years after radical perineal prostatectomy (RPP) among Japanese patients with localized prostate cancer. PATIENTS AND METHODS: In all, 194 patients who had RPP were included in this longitudinal survey. The validated RAND 36-Item Health Survey (SF-36) and the University of California, Los Angeles Prostate Cancer Index (UCLA-PCI) were used to evaluate the HRQL. RESULTS: Among the UCLA-PCI urinary domains, urinary function scores decreased at 3 months after RPP, but they increased 6 months after RPP. Likewise, urinary bother showed a transient decrease at 3 months, but had returned to the baseline level 6 months after RPP. Sexual function (SF) was drastically decreased at 3 months after RPP, but had slightly increased 1 year after RPP. Patients who had a nerve-sparing (NS) RPP showed better SF-related HRQL than those who did not at 6 months after RPP. This favourable alteration involving SF-related HRQL was closely associated with the NS procedure, but not with the patient age. Multivariate analysis showed that later recovery of SF was essentially related to the use of NS RPP, while early recovery of sexual bother was closely related to the patient age. CONCLUSIONS: Our results confirmed the positive effect of RPP on the long-term HRQL in Japanese patients. Although NS surgery conferred the benefit of the recovery of SF, older Japanese patients were not greatly concerned about their decreased SF-related HRQL. The current results provide primary evidence for predicting the alteration of HRQL and understanding the effect of patient age and NS surgery on HRQL after RPP.

Metastatic prostate cancer (PC) is incurable by androgen deprivation therapy alone, due to the presence of androgen-independent/supersensitive cells in hormone-naive PC. A 67-year-old man was diagnosed with PC (Gleason score, 5 + 4) with multiple bone metastases. He was treated by chemohormonal therapy with cisplatin and estramustine phosphate (EMP) followed by maximal androgen blockade, and showed a complete response. As of the time of writing, no clinical or prostate-specific antigen recurrence has been observed for over 15 years, despite cessation of the treatment. This is the first report to indicate a possible cure of metastatic PC by chemohormonal therapy combined with appropriate anti-tumor drugs targeted to both androgen-independent and -dependent clones before the hormone-refractory state.

A 68-year-old male with primary aldosteronism who was scheduled for electroconvulsive therapy (ECT). We used propofol and suxamethonium to induce anesthesia, and measured plasma levels of aldosterone to evaluate the influence of ECT during anesthesia. Although plasma levels of aldosterone increased gradually after ECT, there were no complications including severe hypertension or arrhythmia perioperatively.

A 34-year-old man, 170 cm in height and 70 kg in weight, was scheduled for emergency operation because of gastric perforation due to gastric cancer under general anesthesia. His preoperative blood analysis showed 5.2 x 10(3) mm(-3) of red blood cell, 18 g x dl(-1) of hemoglobin and 48% of hematocrit. Based on this and other data, he was diagnosed as having polycythemia caused by stress. Anesthesia was induced with thiopental and maintained with O2-N2O-sevoflurane. The intraoperative blood loss reached approximately 7,000 ml. Although we administered only 4 units of fresh-frozen plasma (FFP) and 9,150 ml of fluid with no red cell concentrated, his hemodynamic state was stable during surgery. After the surgery, we administered the minimum amount of FFP according to his blood analysis. Although red cell concentrated was not administered in the perioperative period, his general condition remained stable.

A 65-year-old man (blood type O) came to our hospital for transplant of an unrelated kidney (6/6 mismatch of HLA genotype) donated by his living 60-year-old wife (blood type B). The planned right donor nephrectomy was uneventful, with a warm ischemic time of 5 minutes, but her right renal vein was too fragile and weak to be repaired for vascular anastomosis. Therefore, we used an artificial vascular graft (polytetrafluoroethylene) interposed between the donor renal vein and the recipient's left external iliac vein. On the 11th day after surgery, infraphrenic free air (identified by a chest radiograph) made us do an emergent laparoscopic examination that showed a perforation of his sigmoid colon. A transient transverse colostomy was therefore prepared. The transient transverse colostomy was closed 8 months after the kidney transplant. Twelve months after the transplant, the patient is doing well with a serum creatinine level of 150.44 micromol/L (1.7 mg/dL).

OBJECTIVE: : The objective of this study was to identify lymphatic vessels draining from the prostate by using a fluorescence navigation (FN) system. METHODS: : Fourteen subjects were candidates for radical retropubic prostatectomy (RRP) and pelvic lymph node dissection (PLND). After an indocyanine green solution was injected into the prostate during RRP, lymphatic vessels draining from the prostate were analyzed using a FN system. After PLND based on lymphatic mapping by the FN system (in vivo probing) was performed in the external iliac, obturator and internal iliac regions; the fluorescence of the removed lymph nodes (LNs) was analyzed on the bench (ex vivo probing). RESULTS: : Under in vivo and ex vivo probing, the fluorescence intensity of internal iliac nodes was greater than that of external iliac or obturator nodes. CONCLUSION: : The current study suggests that using a FN system after injecting indocyanine green is a safe and rational approach for detecting the lymphatic channel draining from the prostate. The major lymphatic pathway involved in the spreading of prostate cancer appears to relate to internal iliac LNs, which would mean that the standard PLND covering external iliac and obturator regions would not keep the cancer from spreading.
