ABSTRACT
Cesarean section can lead to residual myometrial thickness thinning and cesarean scar syndrome. We report a novel trimming technique for residual myometrial thickness recovery in women with cesarean scar syndrome. Case 1: A 33-year-old woman who developed cesarean scar syndrome (CSS) and abnormal uterine bleeding post-cesarean scar became pregnant following hysteroscopic treatment. The myometrium at previous scar was dehiscent; therefore, a transverse incision was made above the scar. Post-operative uterine recovery failed owing to lochia retention, and developed cesarean scar syndrome again. Case 2: A 29-year-old woman who developed cesarean scar syndrome post-cesarean section became pregnant spontaneously. The myometrium at the previous scar was dehiscent like case 1. Scar repair was performed using a trimming technique during cesarean section; there were no subsequent complications and she conceived again spontaneously. Performing this novel surgical procedure during cesarean section may contribute to residual myometrial thickness recovery in women with cesarean scar syndrome.
ABSTRACT
Chronic inflammation in cesarean scar defect contributes to secondary infertility in women with cesarean scar syndrom; however, it remains unclear about the situation of inflammation in uterine cavity in women with cesarean scar syndrome. This ambidirectional cohort study aimed to explore the effect of inflammation in the uterine cavities of women with cesarean scar syndrome on infertility at a single university hospital. The frequency of chronic endometritis in infertile patients was retrospectively compared between the cesarean scar syndrome group and non-cesarean scar syndrome group. The frequency of endometriosis was also investigated in patients with cesarean scar syndrome who underwent laparoscopy. The level of tumor necrosis factor-α and interleukin-1ß in the uterine cavity was prospectively evaluated in the cesarean scar syndrome group and in women with a history of cesarean section (control group) using an enzyme-linked immunosorbent assay. There was a significant difference in the incidence of chronic endometritis between the cesarean scar syndrome and non-cesarean scar syndrome groups (65.8% and 46.0%, respectively, p = 0.0315). Endometriosis was detected in 51 (70%) patients with laparoscopy. Tumor necrosis factor-α and interleukin-1ß levels in the cesarean scar syndrome group were significantly higher than those in the control group (p = 0.0002 and p = 0.0217, respectively). Our findings suggest that one cause of secondary infertility in women with cesarean scar syndrome is embryo implantation failure-associated chronic endometritis, endometriosis, and chronic inflammation in the uterine cavity.

Gallbladder torsion is a rare disease that requires immediate surgical intervention to avoid maternal and/or foetal sepsis and death. However, preoperative diagnosis is challenging because the disease has no specific symptoms. A 37-year-old pregnant woman at 34 weeks of gestation presented with severe epigastric pain. Ultrasonography and computed tomography scan findings showed a distended gallbladder without stones, floating from the hepatic bed, and laboratory examination demonstrated normal liver function; therefore, we made a diagnosis of gallbladder torsion and performed a caesarean section and an open cholecystectomy under general anaesthesia. This is the first report wherein gallbladder torsion in pregnancy was diagnosed preoperatively. Gallbladder torsion should be considered as a differential diagnosis in case of such imaging findings.

Background: The pathophysiology of neonatal hypoxic-ischemic encephalopathy (HIE) has been studied in several rodent models to develop novel treatments. Although it is well known that high ambient temperature results in severe HIE, the effect of subtle changes in ambient temperature during a hypoxic-ischemic (HI) insult has not been studied. Therefore, in order to clarify the difference of pathophysiological change among the HIE models due to the influence of small changes in chamber temperature, three-step gradual change of 0.5°C each were prepared in ambient temperature during hypoxic exposure. Methods: Blood flow in the left common carotid artery (CCA) of neonatal mice was interrupted using bipolar electronic forceps under general and local anesthesia. The mice were subsequently subjected to 10% hypoxic exposure for 50 min at 36.0, 36.5, or 37.0°C. A control group was also included in the study. The size of the striatum and hippocampus and the volume reduction rate of the hemisphere in the section containing them on the ischemic side were evaluated using microtubule associated protein 2 (MAP2) immunostaining. The accumulation of Iba1-positive cells was investigated to assess inflammation. Additionally, rotarod and open-field tests were performed 2 weeks after HI insult to assess its effect on physiological conditions. Results: MAP2 staining revealed that the higher the temperature during hypoxia, the more severe the volume reduction rate in the hemisphere, striatum, and hippocampus. The number of Iba1-positive cells in the ipsilateral lesion gradually increased with increasing temperature, and there was a significant difference in motor function in the 36.5 and 37.0°C groups compared with the sham group. In the open-field tests, there was a significant decrease in performance in the 37.0°C groups compared with the 36.0°C and sham groups. Conclusions: Even a small gradual change of 0.5°C produced a significant difference in pathological and behavioral changes and contributed to the accumulation of Iba1-positive cells. The arrangement of ambient temperature is useful for creating a rodent model with the appropriate severity of the targeted neuropsychological symptoms to establish a novel therapy for HIE.
ABSTRACT
Ultrasonography and fetal heart rate monitoring are subjective assessments of fetal condition, which warrants the need for objective markers to predict fetal condition. Urinary L-type fatty acid-binding protein (L-FABP) levels correlate with hypoperfusion. Elevated amniotic fluid L-FABP levels may represent fetal tissue hypoperfusion since the amniotic fluid contains fetal urine. In this study, we aimed to analyze the effectiveness of amniotic fluid L-FABP as a predictor of fetal condition. We classified singleton pregnancies into groups based on fetal growth restriction (FGR) with and without fetal blood flow abnormalities (FGR and healthy-FGR groups, respectively) and the non-FGR group (control group). We collected amniotic fluid at the time of vaginal delivery, cesarean section and amniocentesis, and compared the patient characteristics, clinical outcomes and amniotic fluid levels of L-FABP between the groups. We analyzed 153 singleton pregnancies and 186 amniotic fluid samples (FGR group, 6 (3.9%) pregnancies and 23 (12.4%) samples; healthy-FGR group, 15 (9.8%) pregnancies and 20 (10.7%) samples; control group, 132 (86.3%) pregnancies and 143 (76.9%) samples). The amniotic fluid L-FABP level was significantly higher in the FGR group compared to that in the healthy-FGR and control groups. Multivariate analysis revealed that the amniotic fluid L-FABP level was not affected by fetal body weight. Additionally, the amniotic fluid L-FABP levels increased significantly in cases with fetal blood flow abnormalities or early gestational age. Therefore, amniotic fluid L-FABP level may be an objective and accurate predictive marker of fetal condition.

AIM: To analyze the effectiveness of amniotic fluid neutrophil gelatinase-associated lipocalin and L-type fatty acid-binding protein as predictive factors for fetal inflammatory response syndrome. METHODS: We classified single pregnancy cases into the fetal inflammatory response syndrome and nonfetal inflammatory response syndrome groups. We collected amniotic fluid at vaginal delivery and cesarean section and compared the patient characteristics, maternal white blood cell count, C-reactive protein level, and amniotic fluid interleukin-6; neutrophil gelatinase-associated lipocalin; and L-type fatty acid-binding protein levels between the groups. We further analyzed the relationship between L-type fatty acid-binding protein levels and neonatal clinical outcomes. RESULTS: We analyzed 129 pregnancies, of which 36 and 93 (27.9% and 72.1%, respectively) were classified into the fetal inflammatory response syndrome and nonfetal inflammatory response syndrome groups, respectively. We observed significant differences in the maternal white blood cell counts and amniotic fluid interleukin-6 and neutrophil gelatinase-associated lipocalin levels. On the multivariate analysis, the useful predictive factors were maternal white blood cell count and amniotic fluid interleukin-6 and neutrophil gelatinase-associated lipocalin levels. Furthermore, the level of L-type fatty acid-binding protein was significantly higher in the transient tachypnea of the newborn and postnatal respiratory support group than in the control group. CONCLUSIONS: The maternal white blood cell count and amniotic interleukin-6 and neutrophil gelatinase-associated lipocalin levels were effective predictors of fetal inflammatory response syndrome. Amniotic fluid L-type fatty acid-binding protein level was an effective predictor of neonatal respiratory support.
