N/A Acardia is a very rare congenital anomaly occurring in less than 1 in 35,000 deliveries. Acardiac parabiotic twin has been reported only in multiple, monochronic pregnancies. This anomalous fetus is sustained in utero by parasitic anastomoses to the circulation of its usually normal co-twin and is therefore not compatible with extrauterine survival. A case of an acardiac parabiotic twin is described, and the literature concerning the incidence, classification and etiology of acardiac is reviewed.

Gastrointestinal stromal tumor (GIST) of ileum is a rare tumor of gastrointestial tract that arise from primitive mesenchymal cells. GIST occur predominantly in persons over 40 years of age with an equal sex incidence. GIST expresses a heterogenous clinical course and the most important prognostic factors are tumor size, site, degree of mitotic activity, tumor necrosis. We report a case of GIST of ileum, which was misdiagnosed as extrauterine leiomyoma preoperatively.

Isolated tubal torsion is a rare disease that causes acute lower abdominal pain. In most of cases, the ovary and the fallopian tube are together twisted due to an ovarian tumor, but the fallopian tube alone is rarely twisted. Tubal torsion mainly occurs in fertile women, and it rarely occurs prior to menarche and during menopause. We experienced a case where isolated tubal torsion occurred in a perimenopausal female with total abdominal hysterectomy, while the findings showed a normal ovary. We report this case with a brief review of related literature.

N/A Objective : To investigate the mechanisms involved in the mRNA expressions of hCG, LH/CG receptor and in hormone secretion in the trophoblast of normal and abnormal early pregnancy. Methods : hCG, free β-hCG, and progesterone concentrations were measured in serum and the mRNA expressions of α,β-hCG and LH/CG receptor were measured in the placental trophoblast of 22 spontaneous abortion patients (spontaneous abortion group), 20 normal pregnancy women (normal pregnancy group) and 6 hydatidiform mole patients (hydatidiform mole group). Results : 1. Mean values of serum hCG and free β-hCG concentrations were the lowest in spontaneous abortion group (46343.63±40404.18 mIU/ml, p<0.001; 31.34±61.57 mIU/ml, p<0.01 respectively) among the three groups. Mean progesterone concentration was the lowest in spontaneous abortion group (11.84±7.60 ng/ml, p<0.01), too. 2. The expression levels of α,β-hCG were the highest in spontaneous abortion group (4.64±5.47, p=0.015; 4.57±4.42 p=0.002 respectively). The expression levels of LH/CG receptor were not different statistically among the three groups and they were high at the 5th week of gestation, reaching nadir at the 10th week of gestation when the concentrations of serum hCG showed peak values in normal pregnancy group. 3. The correlations between serum hCG and progesterone concentrations were positive in both spontaneous abortion (r=0.827, p<0.001) and normal pregnancy (r=0.438, p=0.054) group. Though they were not significant statistically, the correlations between progesterone concentrations and the levels of α,β-hCG expressions were negative in both spontaneous abortion (r=-0.237, p=0.289; r=-0.211, p=0.347) and normal pregnancy (r=-0.270, p=0.250; r=-0.235, p=0.318) group. In hydatidiform mole group, the correlation between progesterone concentrations and the levels of β-hCG expression was positive (r=0.968, p=0.002). Conclusion : Our results suggest that the mechanisms involved in the secretion of hCG, progesterone and the expression of α,β-hCG, LH/CG receptor be normal in spontaneous abortion as in normal pregnancy and in the both groups, hCG stimulate the secretion of progesterone by autocrine function and control the secretion of itself, through the suppression of the expressions of α,β-hCG and LH/CG receptors. So the cause of spontaneous abortion in early pregnancy may be not placental dysfunction but the defect of embryo itself with poor placental growth.
