Abstract
Bacteraemia brought on by Clostridium perfringens has a very low incidence but is severe and fatal in fifty per cent of cases. C. perfringens is a commensal anaerobic bacterium found in the environment and in the intestinal tracts of animals; it is known to produce six major toxins: α-toxin, β-toxin, ε-toxin, and others. C. perfringens is classified into seven types, A, B, C, D, E, F and G, according to its ability to produce α-toxin, enterotoxin, and necrotising enterotoxin. The bacterial isolates from humans include types A and F, which cause gas gangrene, hepatobiliary infection, and sepsis; massive intravascular haemolysis (MIH) occurs in 7-15% of C. perfringens bacteraemia cases, resulting in a rapid progression to death. We treated six patients with MIH at a single centre in Japan; however, unfortunately, they all passed away. From a clinical perspective, MIH patients tended to be younger and were more frequently male; however, there was no difference in the toxin type or genes of the bacterial isolates. In MIH cases, the level of θ-toxin in the culture supernatant of clinical isolates was proportional to the production of inflammatory cytokines in the peripheral blood, suggesting the occurrence of an intense cytokine storm. Severe and systemic haemolysis is considered an evolutionary maladaptation as it leads to the host's death before the bacterium obtains the benefit of iron utilisation from erythrocytes. The disease's extraordinarily quick progression and dismal prognosis necessitate a straightforward and expedient diagnosis and treatment. However, a reliable standard of diagnosis and treatment has yet to be put forward due to the lack of sufficient case analysis.

Abstract
Clostridium perfringens bacteremia is rare but often fatal. In particular, once bacteremia with massive intravascular hemolysis (MIH) occurs, the mortality rate is extremely high. However, because of its rarity, the detailed pathophysiology of this fulminant form of bacteremia is unclear. To elucidate the detailed pathogenesis of MIH, we retrospectively reviewed the data of all patients with C. perfringens bacteremia from two university hospitals from 2000 to 2014. The medical records and laboratory data of 60 patients with bacteremia, including 6 patients with MIH and 54 patients without MIH, were analyzed. Patients with MIH had higher rates of intense pain at onset, impaired consciousness, shock at presentation, hematuria, metabolic acidosis, and gas formation than patients without MIH. The antibiotic susceptibility of the clinical isolates was not significantly different between the two groups. All patients with MIH, although treated with appropriate antimicrobial agents, died within 26 h of admission due to rapidly progressive acute lung injury or acute respiratory distress syndrome, and the median time from arrival at the hospital to death was only 4 h and 20 min. When clinicians observe intravascular hemolysis in blood samples from patients with characteristic symptoms of MIH, they should prepare for a severe disease outcome. The underlying pathophysiology of fulminant cases must be investigated.

Abstract
ABSTRACT We report 3 individuals with clostridial sepsis, 2 culture-confirmed and 1 assumed based on historical information and autopsy findings. Case 1: a 46-year-old man with history of colon cancer status postcolectomy was found unresponsive and rapidly developed decompositional changes. At autopsy, within 1 day of his death, he had marked gaseous distention of the scrotum and palpable crepitance from the eyes to the feet, with bullae formation in the suprapubic region and left thigh. Postmortem culture of bullae fluid grew Clostridium septicum. Case 2: a 63-year-old woman with history of non-Hodgkin's lymphoma who was identified to have Clostridium perfringens by hospital cultures. Autopsy was performed the day after death. The skin had a generalized red-tan discoloration. The liver had large gas pockets in the parenchyma. Microscopic examination revealed bacterial rods. Other than diverticulosis and mild coronary artery atherosclerosis, no other disease process was identified. Case 3: a 34-year-old man was found dead in his apartment, which was 68°F, just under 1 day after having last been known alive. He was cooled before autopsy and autopsied less than 24 hours after being found. He had fixed anterior lividity, an abdomen that was distended by gas formation, and a scrotum that was distended by gas formation. There was no green discoloration of the abdomen. Glomerular capillaries contained bacterial rods with terminal spores. Because no other cause was identified, the cause of death was certified as probable clostridial sepsis.

Abstract
ABSTRACT An 85-year-old woman with a history of breast carcinoma presented to hospital after gradual onset of abdominal pain with hypotension, jaundice, and massive intravascular hemolysis. This was caused by Clostridium perfringens septicemia originating from a liver abscess. Clostridium perfringens septicemia is a rare infection that has a high mortality rate, given that it is frequently unable to be diagnosed until postmortem examination. The source of the pathogen is usually intra-abdominal. Hepatic abscesses, although an uncommon source of primary clostridial infection, should be considered in such cases.

Abstract
Acupuncture is practiced as a complementary medicine worldwide. Although it is considered a safe practice, pneumothorax is one of its most common serious complications. However, there have been few reports of deaths due to pneumothorax after acupuncture treatment, especially focused on electroacupuncture. We report an autopsy case of a man in his 60s who went into cardiopulmonary arrest and died immediately after receiving electroacupuncture. Postmortem computed tomography (PMCT) showed bilateral pneumothoraces, as well as the presence of numerous gold threads embedded subcutaneously. An autopsy revealed two ecchymoses in the right thoracic cavity and a pinhole injury on the lower lobe of the right lung, suggesting that the needles had penetrated the lung. There were marked emphysematous changes in the lung, suggesting that rupture of bullae might also have contributed to bilateral pneumothoraces and fatal outcome. The acupuncture needles may have been drawn deeper into the body than at the time of insertion due to electrical pulses and muscle contraction, indicating the need for careful determination of treatment indications and technical safety measures, such as fail-safe mechanisms. This is the first case report of fatal bilateral pneumothoraces after electroacupuncture reported in the English literature. This case sheds light on the safety of electroacupuncture and the need for special care when administering it to patients with pulmonary disease who may be at a higher risk of pneumothorax. This is also the first report of three-dimensional reconstructed PMCT images showing the whole-body distribution of embedded gold acupuncture threads, which is unusual.

Leg Med (Tokyo) 2021; 50:101851.

Abstract
Streptococcal toxic shock syndrome (STSS) is a severe infection most commonly caused by group A streptococcus. It is clinically characterized by rapidly progressive multiple organ failure and septic shock. This report presents four fatal cases associated with STSS. In two cases (cases 2 and 3), the portals of entry may be ulcer and mucosa at the surgical site; the initial symptoms in these cases included fever. In the other cases, the portal of entry was unknown; the initial symptom was pain. In two cases (cases 1 and 3), malpractice was suspected before autopsy. At autopsy, blood culture was positive for group A streptococcus in all of the present cases. Although C-reactive protein levels were increased, procalcitonin levels were not markedly elevated. This is the first report of autopsy cases associated with STSS in which postmortem computed tomography was performed; the swelling of muscles and increased concentrations of peripheral subcutaneous tissue without gas may be characteristic findings. Histology revealed extensive bacterial colonies and necrosis with mild neutrophilic reaction in two cases (cases 3 and 4), and hemophagocytosis in two cases (cases 1 and 4). It is essential to perform appropriate examinations and make a proper diagnosis because STSS still has a high fatality rate and medical malpractice is often suspected. In addition, it is important to evaluate STSS again for the reduction of the fatal cases associated with STSS.

Postmortem computed tomography of gas gangrene with aortic gas in a dialysis patient. CEN Case Rep 2020; 9:308-312.

Abstract
Recently, postmortem imaging is sometimes used as an alternative to conventional autopsy. However, there are few case reports of postmortem imaging of dialysis patients. Here, we report a fatal case of gas gangrene involving a 76-year-old man who underwent dialysis. He died suddenly before a diagnosis could be established. Immediately after his death, postmortem computed tomography (PMCT) revealed gas accumulation in his right upper extremity and ascending aorta. Gas gangrene progresses rapidly and may sometimes result in sudden death before it is diagnosed. In this case, PMCT findings were useful to diagnose gas gangrene. Intravascular gas is a common finding on PMCT and is generally caused by cardiopulmonary resuscitation and decomposition. However, the detection of gas in the ascending aorta by PMCT was not described previously. Moreover, Gram stain and culture of the exudate showed anaerobic Gram-positive bacilli which suggested that the gas generation in the blood was caused by Clostridia species. To the best our knowledge, this is the first report of a dialysis patient whose cause of death was determined as gas gangrene using PMCT.

Abstract
Clostridium species are gram-positive, spore-forming, anaerobic rods normally found in the soil and gastrointestinal tract of humans and animals. Spontaneous sepsis due to C. perfringens is not caused by injury, which sets it apart from the classical gas gangrene that typically follows trauma. Spontaneous C. perfringens sepsis often develops as a rapidly progressive intravascular hemolysis and metabolic acidosis, with high mortality rates of over 70% with standard intensive care. In such cases, alpha toxin secreted by C. perfringens is considered the main toxin responsible for intravascular hemolysis, disseminated intravascular coagulopathy, and multiple organ failure. Theta-toxin causes a cytokine cascade, which results in peripheral vasodilation similar to that seen in septic shock. For C. perfringens infections, antibiotics, such as high-dose penicillin, and surgical drainage as early as possible are the principal treatments of choice. However, considering the current mortality rate of sepsis, outcomes have not improved with the current standard treatment for C. perfringens infections. Monoclonal antibody against theta toxin in combination with gas gangrene antitoxin presents a promising therapeutic option.

Abstract
Cases of Clostridium perfringens septicemia, such as liver abscess, often develop a rapidly progressive intravascular hemolysis and coagulation; the mortality rate with current standard care including antibiotics and surgery is high. Herein, we firstly investigated the effects of gas gangrene antitoxin (GGA) (antitoxin against C. perfringens) and recombinant human soluble thrombomodulin (rTM) on the hemolysis, coagulation status, inflammatory process, and mortality in α-toxin-treated rats. Male 11-week-old Sprague Dawley rats were randomly divided into five groups: control group, α-toxin group, GGA group, rTM group, and combined GGA and rTM (combination group). After α-toxin injection, mortality and platelet counts, and hemolysis were observed for 6 h. The fibrin/fibrinogen degradation products (FDP), and plasma high-mobility group box 1 (HMGB1) were also measured at 6 h. The combination group demonstrated 100% survival compared with 50% survival in the α-toxin group and demonstrated significantly improved hemolysis, platelet counts, and lactate levels compared with those in the α-toxin group (p < .01). The FDP and HMGB1 levels in the combination therapy group were significantly lower than those in the α-toxin group (p < .05). Combination therapy with GGA and rTM administration is applicable as adjunct therapy for fatal C. perfringens sepsis.
