The impact of permanent pacemaker implantation on long-term survival after cardiac surgery: A systematic review and meta-analysis.

OBJECTIVES: The long-term impact of permanent pacemaker (PPM) implantation on survival after cardiac surgery remains ill defined. We aimed to investigate the effect of PPM on survival and explore factors driving outcomes using meta-regression according to the type of surgery. METHODS: MEDLINE, EMBASE, and the Cochrane Library Central Register of Controlled Trials were searched through October 2023 to identify studies reporting the long-term outcomes of PPM implantation. The primary outcome was all-cause mortality during follow-up. The secondary outcome was heart failure rehospitalization. The subgroup analysis and meta-regression analysis were performed according to the type of surgery. RESULTS: A total of 28 studies met the inclusion criteria. 183,555 patients (n = 6298; PPM, n = 177,257; no PPM) were analyzed for all-cause mortality, with a weighted median follow-up of 79.7 months. PPM implantation was associated with increased risks of all-cause mortality during follow-up (hazard ratio, 1.22; confidence interval, 1.08-1.38, P < .01) and heart failure rehospitalization (hazard ratio, 1.24; confidence interval, 1.01-1.52, P = .04). Meta-regression demonstrated the adverse impact of PPM was less prominent in patients undergoing mitral or tricuspid valve surgery, whereas studies with a greater proportion with aortic valve replacement were associated with worse outcomes. Similarly, a greater proportion with atrioventricular block as an indication of PPM was associated with worse survival. CONCLUSIONS: PPM implantation after cardiac surgery is associated with a greater risk of long-term all-cause mortality and heart failure rehospitalization. This impact is more prominent in patients undergoing aortic valve surgery or atrioventricular block as an indication than those undergoing mitral or tricuspid valve surgery.

Perforated Small Bowel Adenocarcinoma: An Interesting Presentation of a Rare Disease.

Primary small bowel adenocarcinoma (SBA) is a rare disease with no clear guidelines on screening, diagnosis, or treatment. It has been associated with hereditary cancer syndromes; however, most cases are sporadic and frequently associated with inflammatory bowel disease. We present the case of a 43-year-old male who presented with abdominal pain, nausea, and vomiting and was initially diagnosed with a Crohn's disease flare. He subsequently developed a small bowel perforation and was taken to the operating room for resection of the inflamed segment of the ileum; this was later found to be secondary to an obstructing small bowel adenocarcinoma. He developed an anastomotic leak, which mandated re-exploration and allowed for the completion of an oncologic resection. Small bowel adenocarcinoma is difficult to diagnose and treat due to the absence of clear guidelines and the lack of randomized controlled trials in the setting of a very low incidence.

Horseshoe Abscess as a Rare Complication After Transanal Hemorrhoid Dearterialization With Mucopexy: A Case Report.

Transanal hemorrhoidal dearterialization (THD) is a minimally invasive procedure that has gained popularity as a treatment for symptomatic hemorrhoids. It involves ligating the arterial blood supply to the hemorrhoidal plexus. Compared to conventional ligation or resection, THD is associated with less postoperative bleeding and pain, allowing for same-day surgery discharge. Horseshoe abscess is a rare but known complication of anorectal surgery, characterized by an abscess that extends around the anal canal, often involving the ischiorectal fossa and adjacent structures. Although horseshoe abscesses have been reported after various anorectal surgeries, including hemorrhoidectomy, their occurrence following THD has not been well-documented in the literature. A 72-year-old male underwent THD for rectal prolapse with internal hemorrhoids and presented to the hospital on postoperative day 6 with severe rectal pain. A computed tomography (CT) scan revealed a large complex horseshoe perirectal abscess with fluid and air and significant rectal wall thickening. A rectal examination under anesthesia confirmed the presence of purulent drainage from the anus, and surgical drainage of the abscess was performed. The patient received antibiotics and analgesics and experienced a favorable recovery. The exact pathophysiology of a horseshoe abscess following THD remains unclear, and the incidence and risk factors associated with this complication are not well-established. Moreover, there has yet to be a consensus on the optimal management of horseshoe abscesses after THD, whether through surgical or medical approaches. This case emphasizes the importance of considering horseshoe abscess as a potential complication of THD and highlights the need for further research to understand better its incidence, risk factors, and optimal management strategies.

Effects of Norepinephrine Infusion on Cutaneous Surface Temperatures of the Distal Extremities.

OBJECTIVES: The etiology of vasopressor-induced digital necrosis is poorly understood, but the skin changes resemble those of frostbite, and it is known from experience that patients taking vasopressors have decreased digital temperatures. We aimed to examine the effects of norepinephrine use on surface temperatures of the distal extremities because there have been no studies examining this relation. METHODS: Surface temperatures of all digits, palms, and soles were measured using an infrared thermometer in patients receiving different rates of norepinephrine infusion in the intensive care unit and compared with those not receiving any vasopressors. RESULTS: A total of 101 measurements from 41 unique individuals were obtained. Temperature gradients between the core and the fingertips were consistently more pronounced in those receiving norepinephrine compared with those not receiving norepinephrine and increased with increasing rates of norepinephrine infusion, except with high-dose norepinephrine. Temperature gradients were more pronounced in the toes. CONCLUSIONS: Norepinephrine use was associated with greater core-to-fingertip temperature gradients and were more pronounced in the toes compared with the fingers.

The Effect of Substance Abuse Programs on Positive Drug Screening Tests in Trauma Patients.

BACKGROUND: According to the National Institute on Drug Abuse, West Virginia has the highest age-adjusted rate of drug overdose deaths involving opioids. To combat this crisis, comprehensive drug counseling support services were established within the Cabell Huntington Hospital (CHH) system in October 2018 in Huntington, WV, USA. The purpose of this study was to investigate whether these services significantly reduced the number of trauma patients with a positive urine drug screen (UDS) seen at CHH. METHODS: The trauma registry at CHH was used to obtain data on trauma patients with positive UDS from January 2017 to October 2019, which was divided into groups before and after October 2018. Exclusion criteria were any patients who were prescribed the drug. The percentages of the total number of positive drug screens within each group were calculated, and a t-test analysis was performed to determine the P values. RESULTS: 345 trauma patients with positive UDS were selected. Results showed that there was an overall decrease in the rate of nonprescribed use after October 2018 of benzodiazepines (18.1%-11.5%), cocaine (19.5%-15.3%), opioids (19.1%-12.3%), and oxycodone (10.2%-4.6%). However, none of these changes were statistically significant. There was an increase in the rate of nonprescribed use of amphetamine (20.0%-23.8%) and methamphetamine (14.4%-33.8%). DISCUSSION: Our hypothesis is that the support systems are relatively new, and may need more time to identify and intervene on patients before a statistically significant effect on drug abuse rates in our region can be seen.

Comparison of Geriatric Trauma Outcomes When Admitted to a Medical or Surgical Service After a Fall.

BACKGROUND: Blunt trauma in the geriatric population is fraught with poor outcomes, with injury severity and comorbidities impacting morbidity and mortality. METHODS: We retrospectively reviewed 2172 patients aged ≥65 y who fell, requiring hospital admission between January 2012 and December 2016. There were 403 patients in the surgical arm (SA) and 1769 patients in the medical arm (MA). Ground-level falls were the only mechanism of injury included. We excluded all ICU admissions and deaths within 24 h. RESULTS: There were 5 deaths (1.24%) in the SA and 16 deaths (0.90%) in the MA (P = 0.57). The mean trauma injury severity score survival probability prediction in the SA was 96.9% versus 97.1% in the MA. MA patients had more comorbidities overall than SA patients. There was no difference in mortality between the SA and MA groups in multiple logistic regression models that accounted for trauma injury severity scores (TRISS) and comorbidities. Unadjusted hospital length of stay was 1 d shorter (median; 95% CI -1.4 to -0.6) in the SA and 0.5 d shorter (median; 95% CI -0.8 to -0.1) when adjusted for TRISS and comorbidities using multiple quantile regression. Finally, patients in the SA were 2.1 (95% CI 1.7 to 2.6) times more likely to be discharged home compared with patients in the MA, and this remained significant (OR 1.9; 95% CI 1.5 to 2.5) with simultaneous adjustment for TRISS and comorbidities using multiple logistic regression. CONCLUSIONS: Geriatric blunt trauma patients admitted to surgical services after mechanical falls have no difference in survival, a shorter median length of stay, and increased likelihood of being discharged home compared with patients admitted to medical services.

Adverse Events in the Efficacy of Crotalidae Polyvalent Immune Fab Antivenom vs Placebo in Recovery from Copperhead Snakebite Trial.

OBJECTIVE: To compare the incidence of hypersensitivity reactions following copperhead envenomation treated with Fab antivenom (FabAV) or placebo. METHODS: Patients with copperhead snakebites received treatment and follow-up in a prospective, randomized, double-blind, placebo-controlled trial of FabAV or placebo. The treatment allocation ratio was 2:1 (FabAV:placebo). All of the included patients received at least one dose of study treatment. We reviewed all treatment-emergent adverse events (AEs) using a previously published scale to classify likely hypersensitivity reactions as mild, moderate, or severe. RESULTS: We enrolled 74 patients at 13 sites. Forty-five patients received FabAV, and 29 patients received placebo. Five FabAV patients and 4 placebo patients had moderate envenomations; the rest were mild. Twenty-five FabAV patients and 8 placebo patients had at least 1 AE. Mild skin reactions occurred in 11 (24%) FabAV patients (pruritis, urticaria, rash, ecchymosis, erythema) and 1 (3%) placebo patient (pruritis). Moderate gastrointestinal AEs occurred in 7 (16%) FabAV patients (nausea, vomiting, constipation, diarrhea, oral paresthesia) and in 2 (7%) placebo patients (nausea). Respiratory AEs occurred in 3 (7%) FabAV patients (dyspnea, pulmonary embolism, nasal congestion, sneezing) and no placebo patients. Hypotension occurred in 1 patient in each group. CONCLUSIONS: In a randomized controlled trial of FabAV for copperhead bites, the incidence of hypersensitivity reactions was low. Most reactions were mild skin reactions.

Workforce patterns of rural surgeons in West Virginia.

Rural general surgeons perform a wide variety of procedures and have practices different from those of surgeons in larger communities. Because of this residents completing a classical general surgery training program may not be prepared for the rural setting. The 219 licensed physicians in West Virginia who list general surgery as their practice specialty with the State Board were surveyed to determine the nature of the rural surgery workforce and to examine the caseload of these surgeons. The majority of rural surgeons were satisfied with their current situation; however, 22 per cent stated that they would leave the practice of medicine if financially able. One-third of these surgeons regarded the rural setting as having an adverse impact on their practice. More than half of those surveyed stated that they would not encourage a young person to pursue a career in medicine. For one-third of rural surgeons general medicine was part of daily practice. The caseload varied by community size. Surgeons in communities of fewer than 10,000 people performed a lower percentage of general surgical procedures than surgeons in urban areas. They listed obstetric and gynecologic (9%), urologic (5%), otolaryngologic (9%), and orthopedic (4%) procedures as part of their regular cases. Endoscopic procedures comprise 17 to 24 per cent of total procedures regardless of community size. We conclude that resident surgeons planning to pursue a career in rural general surgery should broaden their operative and general medicine experiences to meet the needs of the communities in which they will serve.

Deer stand-related trauma in West Virginia: 1994 through 1999.

BACKGROUND: Deer hunting is a popular activity in much of the United States. In West Virginia, over 350,000 people each year actively hunt deer. Although injuries and deaths caused by shooting-related incidents have declined, hunting injuries caused by falls from deer stands have not. We present a retrospective study from January 1994 through December 1999 to determine the number of and trauma resulting from deer stand-related incidents in West Virginia. METHODS: Data have been compiled from individual hospital and state trauma registries, patient charts, and Department of Natural Resources logs. RESULTS: A total of 90 individuals have been identified with injuries related to deer stand falls over the 6-year period. There were seven deaths. Most patients had multiple injuries that included extremity fracture (47%), spine fracture (36%), head injury (20%), pelvic fracture (10%), rib/clavicle fracture (11%), solid organ injury (6%), pneumothorax (3%), and other minor injuries (21%). The majority of accidents were associated with home-built as opposed to commercial stands, and most hunters were not using safety straps. Blood alcohol was elevated in only 7% of injured victims. CONCLUSION: Injuries from deer stand falls are a significant cause of morbidity and mortality in this state. This is the largest series of hunting-related deer stand injuries reported in the current literature. Other states have successfully implemented prevention programs that have resulted in a reduction of these types of injuries. Our data emphasize the need to establish and promote preventative education programs for hunters using tree stands.
