Clinical and laboratory evaluation of hospitalized patients with severe ovarian hyperstimulation syndrome

Ovarian hyperstimulation syndrome (OHSS) is an important complication of ovarian stimulation and IVF that enhances patients' morbidity. To evaluate any increased incidence of hospitalization from severe OHSS during 2000, this study analysed certain clinical, ultrasound and laboratory characteristics of hospitalized patients with severe OHSS. These studies were carried out on women undergoing IVF who were hospitalized because of severe OHSS between 1996 and 2000 at the H?pital Antoine Béclère. Patients' ages and serum hormone concentrations were collected on day 3 of ovarian stimulation for various assays, and laboratory and ultrasound measurements taken during ovarian stimulation for IVF were compared. An increase was noted during last year in the frequency of the severe form of OHSS requiring hospitalization (0.9 versus 1.8%, P < 0.05). Patients' ages and hormonal characteristics on day 3 of menstrual cycle, and laboratory and ultrasound variables were similar between the two groups. In addition, the increased incidence of OHSS during 2000 was not associated with any special laboratory or ultrasound parameter, and the policy of ovarian induction had not changed. It is essential to introduce a simple ovarian stimulation protocol providing acceptable IVF results with a minimum of risk.     

Clinical evaluation of intermittent administration of CDDP in advanced ovarian cancer

We examined the effects of intermittent cisplatin therapy (ICDDPT) on advanced ovarian cancer patients (OCP). Most OCPs had received surgical removal of primary lesion, and histopathological analysis indicated epithelial tumors. Four OCPs were stage 3, three were stage 4 and one was stage 2 (n = 8). After surgical treatment and induction chemotherapy, ICDDPT with 20-25 mg/day CDDP was given for 3 or 5 days, every 3 months. During the intervals, maintenance immunochemotherapy with Tegafur and OK-432 was given. Following ICDDPT all patients are alive, the longest survival time being 3 years and 10 months. Three have survived at least 3 years, 1 for at least 2 years and 3 for at least 1 year. Adverse drug reaction (ADR) was analysed with reference to the total dose of CDDP, i.e. under 500 mg, over 500 mg-under 1,000 mg and over 1,000 mg. Abnormal laboratory findings in platelets (thrombocytopenia), Hb, BUN, Creatinine, GOT and GPT were observed at the all doses. These ADR were not increased with the increasing dose so that accumulative toxicity was not observed. Therefore ICDDPT was seen to be effective in treating OCP.     

卵泡发育迟缓者在体外受精中延长使用促性腺激素的临床疗效观察

目的探讨体外受精（IVF）周期中,卵泡发育迟缓者延长使用促性腺激素（Gn）的临床效果。方法将552个IVF周期按Gn用药时间、剂量和获卵数分组,观察组（69个取卵周期,66个移植周期）：Gn起始用量为75IU／d-300IU／d,用药时间≥16d,用至卵泡达到取卵标准为止,获卵数≥4个;对照组（483个取卵周期,464个移植周期）：Gn起始用量为150IU／d～300IU／d,用药时间≤15d,且总Gn用量≤3300IU,获卵数≥4个。比较两组患者的Gn用量及用药时间、获卵数、临床妊娠率、胚胎着床率及治疗结局。结果观察组和对照组的临床妊娠率分别为45．5％（30／66）和51．7％（240／464）;胚胎着床率分别为28．0％（46／164）和30．5％（385／1262）;分娩率分别为37．9％（25／66）和39．4％（183／464）;两组患者的临床妊娠率、胚胎着床率、分娩率等比较,差异均无统计学意义（P〉0．05）。观察组和对照组的多囊卵巢（PCO）和（或）多囊卵巢综合征（PCOS）患者的比例分别为55．1％（38／69）和20．1％（97／483）;基础窦卵泡数分别为（20±11）个和（15±6）个;Gn用药时间分别为（20．8±4．2）d和（10．3±1．8）d;Gn用药总量分别为（3090±1140）IU和（2302±862）IU;血清雌二醇峰值分别为（4595±5181）pmol／L和（7272±6320）pmol／L;获卵数分别为（10±6）个和（14±7）个;移植胚胎数分别为（2．5±0．6）个和（2．7±0．5）个;两组上述各指标比较,差异均有统计学意义（P〈0．01）。结论对IVF周期中卵泡发育迟缓的患者,延长使用Gn有效、方便,能获得满意的临床结局。     

子宫腺肌病与子宫肌瘤的临床及实验室比较分析

探讨子宫腺肌病与子宫肌瘤的临床特点及实验室检查的价值,提高子宫腺肌病的术前诊断率。方法对比分析２５例子宫腺肌病患者和３１例子宫肌瘤患者的临床资料。结果两组患者发病年龄及临床表现相近,但子宫腺肌病的痛经症状明显。Ｂ超的诊断符合率子宫肌瘤组和子宫腺肌病分别为８７．５％和６０．０％,两者相比,有明显差异。     

Elevated HCG outside of pregnancy--diagnostic considerations and laboratory evaluation

Human chorionic gonadotropin (hCG) is a glycoprotein hormone produced by trophoblastic tissues, and its identification is frequently relied upon to establish the diagnosis of pregnancy. Entities other than pregnancy, such as false-positive hCG results, pituitary hCG, exogenous hCG, and both trophoblastic and nontrophoblastic neoplasias, can also cause laboratory assays for hCG to show positive results. Because of their rarity, these conditions are not commonly recognized, and the steps to differentiate between them are not widely known. Discriminating between the causes of elevated hCG in nonpregnant patients can be confusing. An understanding of the differential diagnosis and awareness of available diagnostic modalities are essential for accurate diagnosis and avoidance of potentially harmful treatments. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES: After completion of this article, the reader should be able to state the importance of types of human chorionic gonadotropin (hCG), recall their presence in both trophoblastic and nontrophoblastic neoplasias, and explain how important it is to distinguish between the various causes of an elevated serum hCG to avoid harmful treatments.
