Cervical Spinal Cord Stimulation: A Review.

PURPOSE OF REVIEW: This literature review critically examines existing studies on cervical spinal cord stimulation (cSCS) for the treatment of chronic pain. The objective is to evaluate the current evidence, identify knowledge gaps, and collate data to inform clinical decision-making and suggest future research avenues. The review covers indications, contraindications, surgical and anesthetic approaches, trials, efficacy, and complications of cSCS. RECENT FINDINGS: Recent advancements highlight the evolving role of cSCS in chronic pain management. New neuromodulation techniques involve optimal placement of leads based on the pain's innervation level, maximizing therapeutic outcomes. Contemporary studies underscore the broadening benefits of cSCS, including enhanced functional abilities and sleep quality. However, alongside these innovations come challenges; emerging data bring attention to complications such as hardware issues and infections. Significantly, modern research emphasizes the crucial role of accurate patient selection, factoring in prior therapy responses and comprehensive evaluations. cSCS emerges as a promising tool for chronic pain management, with benefits beyond mere pain relief. As surgical techniques, patient selection criteria, and postoperative care refine, the potential of cSCS expands to benefit a broader patient demographic. However, further comprehensive research is necessary to enhance its application, validate its role earlier in treatment, and ultimately ameliorate the lives of those with chronic pain.

Survey of physician attitudes toward HIV testing in pregnant women in Ohio.

HIV infection among women of childbearing age is still increasing in the United States. In most states, HIV testing of women or neonates during pregnancy is not mandatory. The current study assessed HIV prenatal testing practices among obstetrician-gynecologists and primary care physicians listed in a regional physician referral data base in a predominantly rural region. Between December 2000 and March 2001 a 20-question survey was sent by mail to regional physicians in obstetrics/gynecology and primary care regarding physician practice demographics and prenatal HIV testing practices. Of 1116 surveys sent, 431 were returned (38.6% response). Only 42% of physicians offered universal HIV prenatal testing. Factors associated with universal testing (p < 0.5) included obstetrics/gynecology as the practice specialty (90%) physicians' age younger than 50 years, and a practice with predominantly Medicaid or African American patients. Further educational and public health initiatives may be needed to increase nonselective, universal HIV testing in pregnant women.

Inhibition of gamma interferon decreases bacterial load in peritonitis by accelerating peritoneal fibrin deposition and tissue repair.

Bowel perforation can lead to significant bacterial spillage, which may then cause septic peritonitis, characterized by a systemic inflammatory response and organ dysfunction. There are several reports that have shown that the development of peritoneal adhesions is dependent on inflammatory cytokine levels and that these adhesions can reduce bacterial spread, possibly by sealing off the cecum in the cecal ligation and puncture (CLP) model of septic peritonitis. There have not, however, been any studies that have utilized a strategy to accelerate tissue repair in order to seal off the injured cecum and reduce bacterial spread as well as ameliorate systemic inflammation. In the present study, we demonstrate that the administration of anti-gamma interferon (IFN-gamma) antibody (1.2 mg/kg of body weight, intravenously) accelerated tissue repair via increased fibrin deposition 12 and 24 h after CLP in rats. This increase in fibrin deposition was associated with peritoneal adhesion 24 h after CLP and a reduction in bacterial load compared to the bacterial load of rats given irrelevant antibody. Plasma fibrin levels, however, were not altered after IFN-gamma antibody administration, suggesting that the inhibition of IFN-gamma activity specifically increased fibrin deposition to the site of injury. Furthermore, plasma interleukin-6, used as a marker of systemic inflammatory response, was reduced in CLP rats given IFN-gamma antibody compared to that found in those given irrelevant antibody. These results suggest that the early inhibition of IFN-gamma activity in the CLP model is beneficial by accelerating fibrin deposition in cecal tissue to prevent bacterial spread and reduce the systemic inflammatory response. Importantly, increased fibrin deposition in the ceca was not associated with increased plasma fibrin whereas the latter may have detrimental effects associated with coagulation disorders.
