AbstractGallbladder 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.

BackgroundThe 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.MethodsBlood 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.ResultsMAP2 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.ConclusionsEven 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.

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 FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
