BackgroundIntrahepatic cholestasis of pregnancy (ICP) is a cholestasis condition caused by elevated levels of serum bile acids that mainly occurs in the third trimester of pregnancy. Maternal symptoms include pruritus; elevation of transaminases, biliary enzymes, and bilirubin levels; and abnormal liver function tests. Fetal symptoms include spontaneous preterm labor, fetal distress, and intrauterine death. It is more prevalent in the Caucasians and is rarely found in Asian countries, including Japan. The etiology of ICP has been reported as involving various factors such as, environmental factors, hormone balance, and genetic components. The genetic factors include single-nucleotide polymorphisms (SNPs) in the genes of canalicular transporters, including ABCB4 and ABCB11. It has also been reported that the combination of these SNPs induces severe cholestasis and liver dysfunction.Case presentationHere, we report for the first time a 24-year Japanese case of severe ICP diagnosed by typical symptoms, serum biochemical analysis, and treated with the administration of ursodeoxycholic acid which improved cholestasis and liver injury and prevented fetal death. The sequence analysis showed SNPs reported their association with ICP in the ABCB11 (rs2287622, V444A) and ABCB4 (rs1202283, N168N) loci.ConclusionThe risk of ICP has been reported to be population-specific, and it is rare in the Japanese population. Our case was successfully treated with ursodeoxycholic acid and the genetic sequence analysis has supported the diagnosis. Because genetic variation in ABCB4 and ABCB11 has also been reported in the Japanese population, we need to be aware of potential ICP cases in pregnant Japanese women although further studies are necessary.

Aim The aim is to examine the prevalence of low bone mineral density (BMD) (osteoporosis and osteopenia) of lumbar and femoral bones in puerperal women for the prenatal and postnatal care to ensure their optimal bone health. Methods We analyzed the first scan data of 1079 Japanese puerperal women without bone fracture (mean age 33.5 ± 4.5 years) who had undergone deliveries at Niigata City General Hospital for 10 years. We measured BMDs of the lumbar spine [LS], femoral neck [FN], and total hip [TH] with dual‐energy X‐ray absorptiometry (DXA) within 30 days after delivery. Results The rates of osteoporosis of LS, FN, TH, and comprehensive diagnosis (CD) were 0.6%, 4.8%, 1.5%, and 5.4%, respectively, and osteopenia were 20.2%, 39.5%, 29.3%, and 44.3%, respectively. The multivariable‐adjusted odds ratio (OR) for body mass index (BMI) before pregnancy reflected significant decreases in risk for low BMD with an OR of 0.78 (95% CI: 0.74–0.82) with the 1 kg/m2 increases. In lean women (BMI < 18.5), 71% of them had low BMD. Conclusions Approximately 50% of puerperal women had low BMD without bone fracture. BMD measurements at puerperium, especially for lean women, may be very useful for identifying at risk of osteoporosis in future.

This report presents an unusual case of multiple paraovarian cysts that required emergency surgery due to a paraovarian cyst being entrapped by another paraovarian cyst. Laparoscopic surgery is considered useful for diagnostic and therapeutic purposes and is therefore recommended owing to difficulty in differentiating paraovarian cysts from ovarian cysts.

This clinical image presents an unusual report of simultaneous laparoscopic resection of a hydrocele of the canal of Nuck and an ovarian tumor. Laparoscopic treatment with a proper approach is a useful technique in some cases.
