Second-trimester Abortion.

In 2019, the US Centers for Disease Control reported that 7% of abortions were performed after 13 weeks of pregnancy, a small proportion of all terminations. However, the need for second-trimester abortions will increase commensurate with restrictions to access nationwide. Second-trimester abortions are performed with medications or through a procedure. Health care practitioners serving persons at risk of pregnancy should understand how abortions are performed and how to deliver evidence-based postabortion care. The purpose of this article is to provide a foundation for caring for individuals before, during, and after second-trimester abortion.

A Rare Presentation of Poorly Differentiated Lung Carcinoma with Duodenal Metastasis and Literature Review.

Lung cancer is a common malignancy which is frequently found to metastasize to distant sites including bone, liver, and adrenal glands. There are rare reports of metastases to the gastrointestinal (GI) tract, with the duodenum being the most uncommon. We present a rare case of a poorly differentiated lung carcinoma metastasizing to the duodenum. This case enhances the medical literature as it provides additional distinct features to the clinical and histological presentation of metastatic lung carcinoma to the GI tract. A 61-year-old male with a history of poorly differentiated lung carcinoma presented with worsening dizziness, fatigue, and early satiety. He had extensive workup done in the past for hemoptysis including a computerized tomography scan of the chest which showed a new lobulated, apical lesion and hilar lymphadenopathy. He ultimately had a transthoracic fine-needle aspiration (FNA) of the mass and was later diagnosed with poorly differentiated lung carcinoma. On examination, the patient was noted to be pale, tachycardic, and hypotensive. The patient was noted to have an acute drop in his hemoglobin requiring fluid resuscitation, multiple blood transfusions, and evaluation with an esophagogastroduodenoscopy. He was found to have an oozing ulcer in the third portion of the duodenum whose biopsies showed poorly differentiated carcinoma with areas of neuroendocrine differentiation, similar to his lung biopsy results, which was consistent with metastatic lung carcinoma.

The effect of prophylactic vancomycin powder on infections following spinal surgeries: a systematic review.

OBJECTIVEThe use of vancomycin powder in spine surgery for prophylaxis against surgical site infections (SSIs) is well debated in the literature, with the majority of studies demonstrating improvement and some studies demonstrating no significant reduction in infection rate. It is well known in certain populations that vancomycin powder reduces the general rate of infection, but its effects on reducing the rate of infection due to gram-negative pathogens are not well reviewed. The goal of this paper was to review studies that investigated the efficacy of vancomycin powder as a prophylactic agent against SSI and demonstrate whether the rate of infections by gram-negative pathogens is impacted.METHODSAn electronic search of the published literature was performed using PubMed and Google Scholar in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A variety of combinations of the search terms "vancomycin powder," "infection," "spine," "gram-negative," "prophylaxis," and "surgical site" was used. Inclusion criteria were studies that 1) described an experimental group that received intraoperative intrawound vancomycin powder; 2) included adequately controlled groups that did not receive intraoperative intrawound vancomycin powder; 3) included the number of patients in both the experimental and control groups who developed infection after their spine surgery; and 4) identified the pathogen-causing infection. Studies not directly related to this review's investigation were excluded from the initial screen. Among the studies that met the criteria of the initial screen, additional reasons for exclusion from the systematic review included lack of a control group, unspecified size of control groups, and inconsistent use of vancomycin powder in the experimental group.RESULTSThis systematic review includes 21 studies with control groups. Vancomycin powder significantly reduced the relative risk of developing an SSI (RR 0.55, 95% CI 0.45-0.67, p < 0.0001). In addition, the use of vancomycin powder did not significantly increase the risk of infection by gram-negative pathogens (RR 1.11, 95% CI 0.66-1.86, p = 0.701).CONCLUSIONSThe results of this systematic review suggest that intrawound vancomycin powder is protective against SSI. It is less clear if this treatment increases the risk of gram-negative infection. Further studies are required to investigate whether rates of infection due to gram-negative pathogens are affected by the use of vancomycin powder.
