Cervical ectopic pregnancy: a case report and literature review

We report a case of cervical ectopic pregnancy that was diagnosed using transabdominal ultrasound. Conservative management with methotrexate administration was undertaken and, following a period of heavy bleeding, bilateral uterine artery embolization was performed. Two weeks after presentation, the gestational sac was shown to have reduced in size. We describe the ultrasound findings in this case and discuss those reported in the literature along with the available management options.

Status of low-energy accelerator-based BNCT worldwide and in Argentina

Existing and active low-energy Accelerator-Based BNCT programs worldwide will be reviewed and compared. In particular, the program in Argentina will be discussed which consists of the development of an Electro-Static-Quadrupole (ESQ) Accelerator-Based treatment facility. The facility is conceived to operate with the deuteron-induced reactions ⁹Be(d,n)¹⁰B and ¹³C(d,n)¹⁴N at 1.45 MeV deuteron energy, as neutron sources. Neutron production target development status is specified. The present status of the construction of the new accelerator development laboratory and future BNCT centre is shown.

Accelerator based-BNCT facilities worldwide and an update of the Buenos Aires project

Globally, there are several AB-BNCT facilities, either operational and already treating patients and others still under development. These facilities range from high-energy 30 MeV cyclotrons using the 9Be(p,n) reaction, medium-energy RFQ-DTL accelerators operating at 8-10 MeV with the same reaction, low-energy electrostatic machines (Tandem and single-ended) using the 7Li(p,n) reaction at approximately 2.5 MeV. Additionally, the low-energy ESQ accelerator developed in Argentina, employs the 9Be(d,n) or the 13C(d,n) reactions at 1.45 MeV. This paper presents updated insights into Argentina's AB-BNCT project while also providing a global overview of AB-BNCT developments.

Is medical therapy effective for regional lymphadenitis following BCG vaccination?

We describe 120 patients with regional lymphadenitis following intradermal BCG vaccination. Seventy-eight of the patients were given medical therapy to prevent drainage and suppuration, and 42 patients were followed up without such treatment. The medical therapy group is divided into three subgroups: 36 were given erythromycin stearate, 21 isoniazid, and 21 isoniazid plus rifampin. No statistical difference in the incidence of spontaneous drainage and suppuration was found between the "no therapy" and the "medical therapy" groups. No significant superiority of any specific therapy was shown. If lymphadenitis develops rapidly (in two months), the incidence of spontaneous drainage and suppuration is significantly higher than in patients with slowly developing lesions. Total surgical excision is recommended to prevent spontaneous drainage and chronic suppuration in these rapidly evolving instances.
