Ovarian abscess caused by Helicobacter cinaedi in a patient with endometriosis.

Helicobacter cinaedi is a rarely encountered pathogen that easily induces bacteremia. Various foci of H. cinaedi infection have been reported; however, no case of adnexal abscess caused by H. cinaedi has been reported in the English literature. We herein report a case of ovarian abscess caused by H. cinaedi. A 38-year-old nulligravid Japanese woman was admitted to our hospital with an adnexal abscess. Clinical findings included fever, leukocytosis, and elevated C-reactive protein. Laparoscopic right partial oophorectomy with abdominal lavage was performed. H. cinaedi was isolated from cultures of blood and ovarian abscess fluid after surgery. Intravenous ampicillin/sulbactam was administered for 2 weeks, followed by oral amoxicillin for an additional 2 weeks. The postoperative course was uneventful and clinical findings improved. There was no evidence of relapse. H. cinaedi can cause ovarian abscess and is likely an under-recognized pathogen.

Resolution of dopamine agonist-resistant hyperprolactinemia by hysterectomy: a case report.

Prolactin-producing uterine leiomyomas are very rare. Although hyperprolactinemia rapidly improves after removal of such leiomyomas, no preoperative diagnostic test has been established for prolactin-producing uterine leiomyomas. A 45-year-old Japanese woman, gravida 3 para 3, was referred to our hospital for further examination of hyperprolactinemia resistant to a dopamine agonist. A pituitary prolactinoma was undetectable by brain magnetic resonance imaging. A bromocriptine loading test revealed an increased serum prolactin concentration after loading. Examination for the detection of an ectopic prolactinoma revealed a 9.0 cm diameter uterine leiomyoma that had measured 6.6 cm in diameter about six months before the first visit to our hospital. The hyperprolactinemia rapidly improved after hysterectomy. A prolactin-producing uterine leiomyoma should be considered as a possible cause of hyperprolactinemia resistant to dopamine agonists. Responsiveness to dopamine agonists; deterioration of hyperprolactinemia may be diagnostic for prolactin-producing uterine leiomyomas, although further research is required.

Steroid Pulse Therapy for De Novo Minimal Change Disease During Pregnancy.

BACKGROUND Nephrotic syndrome occurs very rarely, in only about 0.01%-0.02% of all pregnancies, and de novo minimal change disease during pregnancy is especially rare. Nephrotic syndrome and, especially, minimal change disease are highly responsive to steroids, and preterm labor may be avoidable if the maternal condition is improved with steroid therapy. Therefore, prompt diagnosis and proper management are critical to maternal and fetal outcome when severe proteinuria occurs during pregnancy. CASE REPORT A 30-year-old pregnant Japanese woman presented with systemic edema, oliguria, and severe proteinuria and hypoalbuminemia at 25 weeks of gestation, although she was normotensive. The patient had high urinary protein selectivity. Her illness was diagnosed as de novo nephrotic syndrome with high steroid responsiveness rather than pre-eclampsia. She began steroid pulse therapy the day after admission. Complete remission was confirmed after 3 weeks. The patient did not relapse during pregnancy and delivered a healthy male baby at 37 weeks of gestation. A renal biopsy at a relapse after delivery confirmed minimal change disease. CONCLUSIONS In pregnant women with de novo minimal change disease, serious maternal and/or fetal complications may occur if severe proteinuria and hypoalbuminemia are unabated for an extended time. Evaluation of urinary protein selectivity is noninvasive and useful for prediction of steroid responsiveness. Results of urinary protein selectivity can be obtained earlier than results of renal biopsy. Renal biopsy during pregnancy is not always necessary for initiation of steroid therapy. Rapid initiation of steroid pulse therapy may enable quicker achievement of remission and prevent serious perinatal complications.
