Subcutaneous etonogestrel implant combined with endometrial ablation for the treatment of adenomyosis: two case reports.

Adenomyosis is a common disease that affects many premenopausal women. Two patients with adenomyosis, aged 51 and 42 years, presented with dysmenorrhea and increased menstrual volume. They refused laparoscopy or laparotomy surgery and were not eligible for the levonorgestrel-releasing intrauterine system (LNG-IUS). The first patient underwent endometrial ablation and subcutaneous etonogestrel (ENG)-releasing implant placement at the same time. Her symptoms of dysmenorrhea and heavy menstruation improved significantly. When serum follicle-stimulating hormone (FSH) and estradiol (E2) levels suggested menopause, the ENG-releasing implant was removed. However, her abdominal pain recurred and was relieved by medication. For the second patient, an ENG-releasing implant was placed first, and her dysmenorrhea and heavy menstrual volume were relieved. However, the bleeding pattern changed from regular bleeding to prolonged bleeding, which troubled the patient. Endometrial ablation was performed 4 months later to solve the problem. Both patients had improved symptoms and were satisfied with the treatment. For patients with adenomyosis who refuse surgery and are not candidates for the use of LNG-IUS, an ENG-releasing implant combined with endometrial ablation may be an effective alternative.

trans-Bis[4-amino-N-(pyrimidin-2-yl)benzene-sulfonamidato]dipyridine-cobalt(II) hemihydrate.

The asymmeric unit of the title compound, [Co(C(10)H(9)N(4)O(2)S)(2)(C(5)H(5)N)(2)]·0.5H(2)O, contains the distorted octa-hedral trans-[Co(sdz)(2)(py)(2)] (sdz is the sulfadiazine anion and py is pyridine) complex mol-ecule and a half-mol-ecule of water, which lies on a twofold rotation axis. A three-dimensional network is generated by N-H⋯O and O-H⋯O hydrogen bonds between the complex and the water mol-ecules.

Tetra-aqua-bis(pyridine-κN)cobalt(II) bis-[4-amino-N-(6-chloro-pyridazin-3-yl)benzene-sulfonamidate].

The structure of the title compound, [Co(C(5)H(5)N)(2)(H(2)O)(4)](C(10)H(8)ClN(4)O(2)S)(2), consists of a discrete tetra-aqua-bis(pyridine-κN)cobalt(II) cation and two 4-amino-N-(6-chloro-pyridazin-3-yl)benzene-sulfonamidate anions. In the cation, the Co(II) ion sits on an inversion centre and is octa-hedrally coordinated by two pyridine N atoms and four O atoms. A two-dimensional network parallel to (010) is formed via inter-molecular O-H⋯O, O-H⋯N, N-H⋯N and N-H⋯O hydrogen bonds.

[Correlation between the polymorphism of platelet glycoprotein GPIb α Kozak gene and transient ischemic attack].

OBJECTIVE: Genic susceptibility could increase the risk of transient ischemic attack (TIA). The objective of this study is to investigate the relationship between the polymorphism of platelet glycoprotein GPIb α Kozak gene and TIA in Qindao Han population. METHODS: The polymorphisms of platelet glycoprotein GPIb α Kozak gene -5T/C in TIA patients and normal control were detected with sequence-specific primers polymerase chain reaction (PCR-SSP). RESULTS: The prevalence of the CC genotype and C alleles were significantly higher in TIA patients than in the control group (P<0.05). The positive correlation between C allele and TIA was showed by logistic regression analysis (P=0.016). CONCLUSION: The -5T/C polymorphism of the platelet glycoprotein GPIb α Kozak gene is implicated in the pathogenesis of TIA. C allele is an independent risk factor for TIA.
