Uterine rupture is one of the most feared obstetric complications affecting the pregnant woman and fetus. Most of the cases have various risk factors and mainly occur during the second or third trimester. However, spontaneous uterine rupture during the first trimester is extremely rare. We experienced a case of spontaneous uterine rupture in a 36-yr-old multiparous woman without definite risk factors. The initial impression was a hemoperitoneum of an unknown origin with normal early pregnancy. Intensive surgical method would be needed for accurate diagnosis and immediate management in bad situation by hemoperitoneum even though a patient was early pregnancy.

Lymphangioleiomyomatosis (LAM) is a rare disease usually occurring in young women of child-bearing age. It is characterized by a distinctive proliferation of lymphatic smooth muscle cells, especially occurring in the pulmonary parenchyme. The majority of primary LAM occurs in the lung, but there are a few reports of extrapulmonary cases. We report a case of a 21-yr-old female who first complained of low abdominal pain and was referred from a local clinic with the impression of an ovarian cyst. Gynecologic ultrasonography revealed a large posterior pelvic mass with an irregular echogenicity measuring 9.7×4.2 cm in size. Pelviscopy showed a large, thin walled, partly cystic, pelvic mass. The mass was partly removed. Microscopically, the mass was characterized by a haphazard proliferation of smooth muscle cells arranged in fascicular, trabecular, and papillary patterns around a ramifying network of endothelium-lined spaces. The cells were plump or epithelioid with abundant eosinophilic cytoplasm and showed a positive reaction for both alpha-smooth muscle actin and HMB-45 antigen. Surgical and pathological findings were consistent with pelvic retroperitoneal LAM. Despite the numerous treatment attempts, the patient suffered from intractable chylous ascites and developed pulmonary LAM and died due to severe respiratory distress.

Several international initiatives have taken place with themes such as "Men as Partners in reproductive health". Furthermore, many articles have recently been published concerning men's preconception care before pregnancy. However, little attention has been paid to this field in Korea. The concept of preconception health and health care for men is very important for pregnancy outcomes, and furthermore, for the health of their future families. Men's contribution to the pregnancy is clear for planned pregnancy and also offers an opportunity for disease prevention and health promotion in men themselves. This paper reviews the important concept of men's health for preparing for pregnancy, and summarizes key component of a comprehensive approach to optimizing the preconception health status of men as expecting fathers. In fact, many clinicians including most obstetricians-gynecologists in Korea are not trained to provide preconception health and care for men. In addition, no consensus has been developed on basic guidelines for preconception care including the pregnancy planning for men and women, laboratory tests before pregnancy, vaccination programs, and much more information on preparing for a successful pregnancy. To improve preconception care for men in Korea, many barriers must be overcome, such as lack of national services, financing, organization, and men's and women's understanding of the importance of preconception health for their pregnancy. Therefore, much more research is needed on men's preconception care in Korea.

Irregularity and complexity of the heart rate dynamics of SGA fetuses are lower than that of normal ones. Also, canonical ensemble in SGA fetuses is higher than in normal ones, suggesting that the FHR control system has multiple complex interactions. Along with the clear difference between the two groups' non-linear chaotic dynamics in FHR patterns, we clarified the hidden subtle differences in linearity (e.g., canonical ensemble). The decrease in non-linear dynamics may contribute to the increase in linear dynamics. The present statistical methodology can be readily and routinely utilized in obstetrics and gynecologic fields.
