Odogwu NM. Role of short interpregnancy interval, birth mode, birth practices, and the postpartum vaginal microbiome in preterm birth. FRONTIERS IN REPRODUCTIVE HEALTH 2023; 4:1082199.

Abstract
There have been widely documented beneficial role of vaginal Lactobacillus species as an important biomarker for vaginal health and healthy pregnancy progression. When translating this to clinical settings, pregnant women with low proportions of Lactobacillus and commensurately high proportion of rich and highly diverse abnormal microbiota are most likely to encounter negative pregnancy outcome such as preterm birth and postpartum complications. However, multiple literatures have also addressed this notion that the absence of a Lactobacillus-dominated microbiota does not appear to directly imply to a diseased condition and may not be a major determinant of negative obstetric outcome. Caesarian delivery is notably a risk factor for preterm birth and postpartum endometritis, yet recent data shows a trend in the overuse of CS across several populations. Growing evidence suggest the potential role of vaginal/uterine cleaning practice during CS procedures in influencing postpartum infections, however there is a controversy that this practice is associated with increased rates of postpartum endometritis. The preponderance of bacterial vaginosis associated bacteria vagitype at postpartum which persist for a long period of time even after lochia regression in some women may suggest why short interpregnancy interval may pose a potential risk for preterm birth, especially multigravidas. While specifically linking a community of microbes in the female reproductive tract or an exact causative infectious agent to preterm birth and postpartum pathologies remains elusive, clinical attention should also be drawn to the potential contribution of other factors such as short interpregnancy interval, birth mode, birth practices and the postpartum vaginal microbiome in preterm birth which is explicitly described in this narrative review.

Abstract
Group A Streptococcus (GAS; Streptococcus pyogenes) is a facultative gram-positive coccus, uncommonly colonizing parturient genitalia, where its presence can potentially lead to a life-threatening invasive infection after delivery. GAS infection typically occurs within the first 4 days post-partum and is characterized by high fever, chills, flashing, abdominal pain, and uterine tenderness. Nonetheless, patients with GAS puerperal sepsis may have an unusual presentation, when fever is absent, and the symptoms and signs can be mild, non-specific, and not indicative of the severity of infection. This unusual presentation may lead to a delayed diagnosis and increase the risk for severe puerperal sepsis. Therefore, in these cases, a high index of suspicion and prompt early antibiotic and surgical treatment is crucial to saving the parturient’s life.

Abstract
AIM Perinatal group A streptococcal infection is a rare but life-threatening condition. Few reports have focused on its clinical characteristics and how to prevent deterioration. We report our experience with two antenatal fatal cases and reviewed 96 cases in the literature to assess the clinical characteristics of group A streptococcal infection. METHODS English-language clinical reports of antenatal and postnatal group A streptococcal infection in 1974-2019 were retrieved and examined. Relationships between clinical characteristics and maternal outcomes were assessed. RESULTS Univariate analysis revealed that antenatal group A streptococcal infection was significantly associated with an age of ≤19 or ≥ 35 years, cesarean section, sore throat as an initial symptom, positive throat culture, maternal death and fetal death. Multivariate analysis revealed that antenatal onset (odds ratio = 7.922, 95% confidence interval = 1.297-48.374; P = 0.025) and a quick sepsis-related organ-failure assessment score (qSOFA; low blood pressure, high respiratory rate or altered mental status) of ≥2 (odds ratio = 6.166, 95% confidence interval = 1.066-35.670; P = 0.042) were significantly related to maternal death. CONCLUSION Per our findings, antenatal group A streptococcal infection was significantly associated with maternal and fetal death. Further, the antenatal infection was revealed as a more critical risk factor. We suggest that the presence of any sign related to the qSOFA is a potential clue suspecting perinatal group A streptococcal infection in primary obstetric facilities.

Abstract
Background: Streptococcal Toxic Shock Syndrome (STSS) is a serious condition that can arise from streptococcal postpartum endometritis. It is associated with a substantial increase in mortality rate and can rarely result in multiorgan infarction. Early recognition plays a vital role in patients' outcome. Objective: To report a case of complicated STSS and review the literature for previous case reports of streptococcal postpartum endometritis to determine if STSS diagnostic criteria (published by the Centers for Disease Control and Prevention) were fulfilled. Case presentation: This is a 41-year-old woman who presented 5 days after an uncomplicated vaginal delivery with endometritis complicated by invasive group A β-hemolytic streptococcus (GAS) infection and confirmed toxic shock syndrome. The patient was initially admitted to the critical care unit due to hemodynamic compromise requiring intravenous (IV) fluids, IV antibiotic therapy with penicillin and clindamycin, and IV immunoglobulin therapy. The patient subsequently developed multi-organ infarctions, acute respiratory distress syndrome requiring noninvasive respiratory support, and severe reactive arthritis. Literature review revealed 15 case reports of GAS postpartum endometritis, five met criteria for confirmed STSS. One patient died from severe septic shock leading to cardiopulmonary arrest. Thirteen out of 15 cases of postpartum endometritis occurred after uncomplicated vaginal delivery. Conclusion: STSS is a serious and possibly fatal medical condition that requires early diagnosis and treatment to prevent poor patient outcomes and death. Careful consideration to the patient's postpartum clinical presentation with the implementation of an intradisciplinary approach should be utilized.

Abstract
Introduction Sanitary tampons have been in existence for over 60 years. Their use may present certain health risks, potentially associated with an abnormal change of microbial flora in the vagina (e.g., toxic shock syndrome). Tampon production and marketing are regulated differently in different countries. In Australia, Canada and the USA, tampons are classified as Class-II medical devices and their marketing requires pre-clinical and clinical studies, including microbiological trials. In Europe, tampons are considered consumer products and safety-related data are provided only if the manufacturer deems them to be useful. Sterility of these products is not requested by law; thus they may represent a potential vehicle for microorganisms. Due to the lack of data on microbial characteristics of tampons, an analytical investigation was carried out to characterize and quantify the microbial flora present on sealed tampons of various brands present on the market in Italy. Methods Traditional cultural methods were used to characterize and quantify bacteria and fungi. Identification of colonies was performed with biochemical techniques. Results Results showed low microbial concentrations in 93% of the positive samples. A rare presence of opportunistic pathogens was detected and a few samples (6%) were characterized by bacterial species of human origin. Conclusions In the light of these data, the examined tampons were found to have good hygienic quality. Nevertheless, to minimize the microbial risks linked to the use of these products, strict hygienic rules during their production and manipulation have to be adopted.

Abstract
Background Pyomyositis is typically caused by Staphylococcus aureus, and is rare in temperate climates, although its prevalence has been recently increasing. This infection often involves the thigh, and is associated with immunodeficiency. Case presentation We report the case of a healthy 20-year-old Japanese woman who experienced a fever and continuous pain for several days. She was admitted to our hospital and was diagnosed with pyomyositis after we discovered an abscess between the muscles of her dorsal distal left thigh using computed tomography. This is a rare case of thigh pyomyositis, as it was caused by group A streptococcus and occurred in an immunocompetent adult from a temperate climate. Conclusions Our review of the literature revealed that group A streptococcus pyomyositis typically occurs in temperate climates, among young adults without any underlying disease, and is associated with a poorer prognosis, compared to general pyomyositis. We suggest that pyomyositis should be considered when immunocompetent adults present with apparently idiopathic inflammatory muscle lesions.

Abstract
Ignaz Semmelweiss made one of the most important contributions to modern medicine when he instituted handwashing in an obstetric clinic in Austria in 1847, decreasing mortality there from more than 10% to 2%. Unfortunately, puerperal sepsis remains a leading cause of maternal mortality throughout the world. Group A streptococcus (GAS), Streptococcus pyogenes, is an organism associated with high rates of morbidity and mortality from puerperal infections. When associated with sepsis, known as streptococcal toxic shock syndrome, mortality rates approach 30-50%. Group A streptococcus can cause invasive infections in the form of endometritis, necrotizing fasciitis, or streptococcal toxic shock syndrome. The clinical presentation of women with puerperal GAS infections is often atypical with extremes of temperature, unusual and vague pain, and pain in extremities. Toxin production by the organism may allow GAS to spread across tissue planes and cause necrosis while evading containment by the maternal immune system in the form of a discrete abscess. Endometrial aspiration in addition to blood cultures may be a useful rapid diagnostic tool. Imaging may appear normal and should not dissuade the clinician from aggressive management. When suspected, invasive GAS infections should be treated emergently with fluid resuscitation, antibiotic administration, and source control. The optimal antibiotic regimen contains penicillin and clindamycin. Source control may require extensive wound or vulvar debridement, hysterectomy, or a combination of these, which may be life-saving. The benefit of immunoglobulins in management of puerperal GAS infections is unclear.

Abstract
OBJECTIVE To describe microbiological characteristics and epidemiologic features of an outbreak of postpartum endometritis. METHODS Various markers were investigated in five patients and three throat carriage isolates of Streptococcus pyogenes obtained during an outbreak of endometritis occurring in a 13-week period. Molecular characterization included biotyping, T-serotyping, emm gene sequence and restriction, pulsed-field gel electrophoresis (PFGE), and random amplified polymorphic DNA (RAPD) analysis. RESULTS Biotype, T-serotype, and genotypic data (emm analysis, PFGE, and RAPD analysis) revealed a close relationship among the isolates from three patients, suggesting that cross-contamination had occurred. These isolates were biotype 1, T type 28, and emm type 28. The isolates from one patient and one carrier differed from those of the index patient by minor variations of the emm amplicon restriction pattern, PFGE pattern, or RAPD pattern. The remaining isolates were phenotypically and genetically different. CONCLUSION Identification of different isolates demonstrated that different strains may circulate simultaneously during a true outbreak and that the predominant strain might persist for several months.
