Cataract Surgery in HIV Seropositive Patients: Long-Term Follow-Up

Purpose: To study epidemiology and clinical findings of cataract in HIV+ patients.

Methods: A total of 32 HIV+ patients, 11 with uveitis/retinitis before surgery and 21 without, mean follow-up 44.9 ± 36.6 months, and 114 HIV- patients, 57 with uveitis/retinitis before surgery and 57 without, were retrospectively compared.

Results: Visual acuity improved in all HIV+ patients (p < 0.001), who were younger (p = 0.01) and more frequently males (p = 0.027). HIV+ patients with uveitis prior surgery improved less (p = 0.046) than HIV- (p < 0.001); their anterior chamber inflammation was similar to baseline. Male sex (p = 0.005), younger age (p < 0.001), dyslipidaemia (p = 0.058), HBV+ (p = 0.037), and unilateral cataract (p = 0.001) were more frequent in HIV+ patients with senile cataract, but they showed the same postoperative course as HIV- patients.

Conclusion: Cataract surgery in HIV+ patients is safe and effective. Uveitis prior to surgery did not significantly affect the postoperative course. Systemic comorbidities are more frequent in HIV+ patients with senile cataract than in HIV- subjects.     

Risk factors and management of stoma-related obstruction after laparoscopic colorectal surgery with diverting ileostomy

BackgroundStoma-related obstruction (SRO) is defined as small bowel obstruction occurring around the limbs of diverting ileostomy (DI). This study was aimed to investigate the incidence, risk factors, and management of SRO after laparoscopic colorectal surgery with DI creation.MethodsThis study included 155 patients who underwent laparoscopic colorectal surgery with DI creation for rectal cancer (n = 138), ulcerative colitis (UC) (n = 14), and familial adenomatous polyposis (FAP) (n = 3) between 2011 and 2019. Univariate and multivariate analyses were performed to identify the risk factors of SRO.ResultsThe incidence of SRO was 7.7% (n = 12), and it was significantly lower (P < 0.01) in patients with lower anterior resection or intersphincteric resection (4.3%) than in those with ileal-pouch anal anastomosis (IPAA) (35.2%). The multivariate analysis revealed that IPAA was independently associated with the development of SRO (P = 0.001; odds ratio, 9.4; 95% confidence interval, 2.5–35.4). Eleven of 12 patients (92%) with SRO required trans-stomal tube decompression, and 8 of those (67%) underwent early stoma closure.ConclusionIPAA was an independent risk factor of SRO in laparoscopic colorectal surgery with DI creation. Early stoma closure was needed in most cases of SRO.     

Antibiotic prophylaxis in orthognathic surgery: an overview of systematic reviews

The purpose of this overview was to assess different antibiotic regimens used in orthognathic surgery and to establish an evidence-based protocol so that beneficial and adverse effects can be determined. A comprehensive literature search for systematic reviews and/or meta-analyses was conducted in MEDLINE (PubMed), EMBASE, and the Cochrane Library until March 2020. Grey literature was investigated in Google Scholar, and a manual search was done of references lists. Two meta-analyses and four systematic reviews met the inclusion criteria. The AMSTAR-2-tool was used to ascertain the potential risk of bias in the included studies, which presented moderate to high methodological quality. Lower infection rates were associated with long-term therapies of penicillin, cefazolin-cephalexin, and amoxicillin-clavulanic-acid, with rates varying from 0% - 3.13%. Higher rates were reported in placebo groups (52.6%) and short-term penicillin therapy (60%). Side effects were reported with cefazolin, clindamycin, and penicillin therapies, including nausea, pain, swelling, headache, vomiting, and skin rash. Evidence suggests that long-term antibiotics can reduce the risk of a surgical site infection (SSI) in orthognathic surgery, but there is uncertainty regarding the effects of one dose of antibiotics preoperatively versus short-term antibiotics. In the same way, intravenous penicillin, cefazolin, clindamycin, and amoxicillin-clavulanic acid kept the infection rates associated with bimaxillary procedures under 3.5%.     

Fístulas posquirúrgicas de líquido cefalorraquídeo tras cirugía transesfenoidal de adenomas hipofisarios: análisis de una serie de 302 intervenciones

IntroductionTranssphenoidal surgical removal is the preferred treatment of most pituitary adenomas. Postoperative cerebrospinal fluid (CSF) leakage is the leading cause of morbidity after this procedure, with an incidence rate that varies from 0,5-15% in the main published series.ObjectivesThe primary objective of this study was to establish the incidence of postoperative CSF leakage in a sample of surgeries performed at the University Hospital of La Ribera by the same surgical team. The secondary objectives were to: ascertain the distinctive features between patients with and without postoperative CSF leakage, identify risk factors for their development, evaluate the relationship between the surgical technique for closing the sella turcica and the onset of postoperative CSF leakage and evaluate different treatment regimens for this complication.MethodsThe data of 302 consecutive transsphenoidal surgical procedures for pituitary adenoma removal which were performed between 1999 and 2017 were retrospectively reviewed.Results and conclusionsThe incidence of postoperative CSF leakage in our series was 2,3% (in accordance with similar published studies). It was possible to correlate intraoperative CSF leakage with two variables: pituitary macroadenoma and tumors with suprasellar extension (P < .005). This correlation did not exist for postoperative CSF leakage. We found a statistically significant correlation between intraoperative and postoperative CSF leakage (P < .005). Due to the low incidence of postoperative CSF leakage in our series, it was not possible to identify risk factors for its development.     

Long-term skeletal stability in the treatment of mandibular prognathism with a physiological positioning strategy

Our aim was to evaluate the long-term skeletal stability of the mandible in 21 patients after orthognathic surgery with physiological positioning. The measurement points SNB, B point (X, Y), Pog (X, Y), and the angle of the ramus were measured on cephalometric photographs to assess skeletal stability preoperatively, immediately after operation, and one and two years postoperatively. In addition, we evaluated the clinical symptoms of disorders of the temporomandibular joint (TMJ). The analysis of the cephalometric photographs showed that SNB, B point X, and Pog X showed no significant differences among the postoperative time points. On the other hand, B point Y and Pog Y showed no significant differences throughout the study period. We compared the angle of the ramus before operation and two years postoperatively, and no significant difference was found. In addition, no cases showed any pathological symptoms of disorders of the TMJ two years postoperatively. The long-term stability after orthognathic surgery with physiological positioning was confirmed, and it seems to be a reliable orthognathic treatment in patients with mandibular prognathism.

Geriatric Comanagement of Older Vascular Surgery Inpatients Reduces Hospital-Acquired Geriatric Syndromes

ObjectiveThis study evaluates the impact of a novel model of care called Geriatric Comanagement of Older Vascular surgery inpatients on clinical outcomes.Design, Setting, and ParticipantsA pre-post study of geriatric comanagement, comparing prospectively recruited preintervention (February–October 2019) and prospectively recruited postintervention (January–December 2020) cohorts. Consecutively admitted vascular surgery patients age ≥65 years at a tertiary academic hospital in Concord and with an expected length of stay (LOS) greater than 2 days were recruited.InterventionA comanagement model where a geriatrician was embedded within the vascular surgery team and delivered proactive comprehensive geriatric assessment based interventions.MethodsPrimary outcomes of incidence of hospital-acquired geriatric syndromes, delirium, and LOS were compared between groups using univariable and multivariable logistic regression analyses. Prespecified subgroup analysis was performed by frailty status.ResultsThere were 150 patients in the preintervention group and 152 patients in the postintervention group. The postintervention group were more frail [66 (43.4%) vs 45 (30.0%)], urgently admitted [72 (47.4%) vs 56 (37.3%)], and nonoperatively managed [52 (34.2%) vs 33 (22.0%)]. These differences were attributed to the coronavirus disease 2019 pandemic during the postintervention phase. The postintervention group had fewer hospital-acquired geriatric syndromes [74 (48.7%) vs 97 (64.7%); P = .005] and reduced incident delirium [5 (3.3%) vs 15 (10.0%); P = .02], in unadjusted and adjusted analyses. Cardiac [8 (5.3%) vs 30 (20.0%); P < .001] and infective complications [4 (2.6%) vs 12 (8.0%); P = .04] were also fewer. LOS was unchanged. Frail patients in the postintervention group experienced significantly fewer geriatric syndromes including delirium.Conclusions and ImplicationsThis is the first prospective study of inpatient geriatric comanagement for older vascular surgery patients. Reductions in hospital-acquired geriatric syndromes including delirium, and cardiac and infective complications were observed after implementing geriatric comanagement. These benefits were also demonstrated in the frail subgroup.
