Pyometra is an uncommon condition in general population and caused by impairment of natural drainage of the cervix as a result of benign or malignant diseases, Spontaneous uterine perforation, a very rare complication of pyometra, carries significant morbidity and mortality and should be considered in the differential diagnosis of other peritonitis. Preoperative diagnosis of perforated pyometra is difficult due to old age, poor general condition, and symptoms that present as abdominal pain related to gastrointestinal diseases. If a diagnosis of perforated pyometra is delayed, then it will be associated with increased morbidity and mortality. In the causes of uterine perforation, pyometra should be considered because of requiring proper intervention. A diagnosis of spontaneous perforated pyometra should always be kept as a possibility in all cases of abdominal pains associated with peritonitis in elderly women.

Intestinal obstruction occurs rarely as a cause of acute abdominal pain during pregnancy. It is very difficult to make diagnosis, as nausea, vomiting and abdominal pain are commonly associated with pregnancy, and X-rays are avoided if possible. However, delayed diagnosis can cause intestinal strangulation, which results in a high incidence of maternal morbidity, mortality, premature labor, and fetal loss. The incidence of intestinal obstruction seems to increase at the time of rapid uterine size changes such as between 16~20 weeks, 32~36 weeks or even in the puerperium. The possibility of intestinal obstruction must always be kept in mind when a pregnant woman with an operation scar on her abdomen develops abdominal pain. We present a case of small bowel obstruction during early pregnancy with a brief review of the literature who had the history of right salpingo-oophorectomy and appendectomy operation.

Heterotopic pregnancy, combined intrauterine and extra-uterine (ectopic) pregnancy, is a potentially fatal condition that rarely occurs in natural conception cycle. There has been a rise of this entity mainly due to ovulation induction and in vitro fertilization performed in women undergoing assisted reproductive technology. Diagnosis is often delayed causing life threatening situations, since heterotopic pregnancy is still rare and unexpected in natural conception. We report a case of patient with spontaneous heterotopic pregnancy in the fi rst trimester with a review of the literature. Transvaginal ultrasound confi rmed heart activity of both embryos in uterus and the right ampulla portion.

This study aims to develop the hydration heat reducing material (powder type) to lower the heat of hydration of mass members in the extremely hot weather condition. In this study, we applied the developed material to the concrete that used two kinds of binders with cement and evaluate the concrete properties with it.

Eco-friendly concrete contains only 5% of cement yet achieves equal or greater strength compared to conventional concrete, reducing salt-attack impact and hydration heat by more than 30% and ensuring higher construction quality for underground structures. Furthermore, eco-friendly concrete can reduce up to 90% of carbon dioxide emissions compared to traditional concrete, enabling a reduction of approximately 6,000 tons of carbon emissions for 1,000 of apartment units construction. This is equivalent to planting around 42,000 trees

Concrete bricks and hollow concrete block products manufactured using ordinary portland cement react with salt and carbon dioxide absorbed from the soil and atmosphere in the use environment, causing contamination such as efflorescence. This is due to the reaction between calcium hydroxide, a cement hydration product, and carbon dioxide, producing and eluting calcium carbonate. This study was a preliminary study to compare and evaluate the reduction of efflorescence in concrete bricks and hollow concrete block products manufactured using carbon dioxide reaction hardening cement. The purpose was to evaluate the efflorescence occurrence in products using ordinary Portland cement.

S. lugdunensis 감염성 심내막염은 국내에서 거의 보고가 없었고, 매우 드물지만 심한 합병증 및 높은 사망률을 보이는 질환이다. 저자들은 항생제 및 수술적 치료로 완치된 자연 판막에서 발생한 S. lugdunensis 감염성 심내막염 1예를 경험하였기에 이를 문헌고찰과 함께 보고하는 바이다. A 37-year-old woman presented to our hospital with a 1-month history of fever. She also complained of lower leg pain. Transthoracic echocardiography showed large vegetations on the mitral valve leaflets. Staphylococcus lugdunensis was isolated from blood cultures. She was diagnosed with infectious endocarditis due to S. lugdunensis and was treated with antibiotics and surgery. Infective endocarditis caused by S. lugdunensis can be invasive and often resembles endocarditis due to Staphylococcus aureus. Thus, whenever this organism is found in patients with endocarditis, early surgical treatment of the infected valve should be considered. (Korean J Med 2011;80:212-215)

Biliary cast describes the presence of casts within the biliary tree. It is resultant sequel of cholangitis and hepatocyte damage secondary to bile stasis and bile duct injury. Biliary cast syndrome was first reported in patient undergone liver transplantation. The pathogenesis of biliary cast is not clearly identified, but proposed etiologic factors include post-transplant bile duct damage, ischemia, biliary infection, or post-operative biliary drainage tube, Although biliary casts are uncommon, most of biliary cast syndrome are reported in the liver transplant or hepatic surgery patients. A few reports have been published about non-transplant or non-liver surgery biliary cast. We report two cases of biliary cast syndrome in non-liver surgery patients.
