SummaryIntroduction Pre-operative Vitamin D deficiency is markedly prevalent in prospective bariatric surgery patients. While bariatric surgery leads to significant weight loss, it can exacerbate or prolong Vitamin D deficiency. We systematically reviewed the literature to assess whether secondary hyperparathyroidism is maintained in the medium to long term in patients following the Roux-en-Y gastric bypass. Methods A comprehensive literature search was conducted through Medline, Embase, Scopus, Web of Science, Dare, Cochrane library and HTA database. The search terms used were bariatric surgery, gastric bypass and hyperparathyroidism. Results Fourteen studies were included (n = 2688 subjects). Parathyroid hormone levels rose gradually from a mean pre-operative level of 5.69 ± 1.2 pmol/L to 6.36 ± 0.77 pmol/L, 7.59 ± 0.73 pmol/L and 8.29 ± 1.41 pmol/L at 2 years, between 2 and 5 years, and beyond 5 years, respectively. Vitamin D levels slowly fell to a mean of 20.50 ± 4.37 ng/mL and 20.76 ± 3.80 ng/mL between follow-up intervals 2–5 years and beyond 5, respectively. Conclusion It appears that hyperparathyroidism persists at 5-year follow-up after gastric bypass, despite most patients being supplemented with calcium and Vitamin D.

Pre-operative Vitamin D deficiency is markedly prevalent in prospective bariatric surgery patients. While bariatric surgery leads to significant weight loss, it can exacerbate or prolong Vitamin D deficiency. We systematically reviewed the literature to assess whether secondary hyperparathyroidism is maintained in the medium to long term in patients following the Roux-en-Y gastric bypass.A comprehensive literature search was conducted through Medline, Embase, Scopus, Web of Science, Dare, Cochrane library and HTA database. The search terms used were bariatric surgery, gastric bypass and hyperparathyroidism.Fourteen studies were included (n = 2688 subjects). Parathyroid hormone levels rose gradually from a mean pre-operative level of 5.69 ± 1.2 pmol/L to 6.36 ± 0.77 pmol/L, 7.59 ± 0.73 pmol/L and 8.29 ± 1.41 pmol/L at 2 years, between 2 and 5 years, and beyond 5 years, respectively. Vitamin D levels slowly fell to a mean of 20.50 ± 4.37 ng/mL and 20.76 ± 3.80 ng/mL between follow-up intervals 2-5 years and beyond 5, respectively.It appears that hyperparathyroidism persists at 5-year follow-up after gastric bypass, despite most patients being supplemented with calcium and Vitamin D.

A number of factors were evaluated as predictors of field dependence (Embedded-Figures Test score) in alcoholics. In our sample, duration of excessive drinking and symptomatology of alcohol dependence were significantly related to the level of field dependence. These results fail to corroborate earlier findings and suggest that heightened field dependence in alcoholics is, at least partly, a consequence of alcohol misuse. In addition, a strong relationship was detected between the alcoholics' degree of anxiety and their degree of alcohol dependence. Possible bases for such a relationship are discussed.

Beneficial effect of cryopexy on 180 degrees to 360 degrees of avascular retina was demonstrated in 7 prematurely born infants (14 eyes) affected with advanced retinopathy of prematurity. Intravitreous new vessels were present in all eyes before treatment. The treatment of one eye was supplemented with scleral indentation. Only one of the treated eyes went on unfavourably with retrolental fibroplasia and consecutive loss of visual acuity. We believe that cryopexy, when administered promptly, when limited to the avascular zone, and when supplemented with scleral indentation in cases with important vitreous traction, is a valuable treatment with fewer risks than unchecked evolution for advanced cases of retinopathy of prematurity.

Twelve diabetic patients presenting a preproliferative or proliferative retinopathy were the subjects of our study. We studied the modifications of the visual fields, analyzed by computerized perimetry, after panretinal photocoagulation (PRP). For every patient, two techniques of PRP were applied, one on each eye: C: conventional scattered treatment, G: cluster technique. Computerized perimetry was done within 10 days prior to PRP, and 4 to 8 weeks following it. We used the Octopus 500, programs 36 (0 to 30 degrees) and 44 (30 to 60 degrees). It appears that, before any treatment, there is a loss of retinal sensitivity excepted the more central zone. Concerning the loss of sensitivity, although the number of laser burns, is greater in group G, there is no statistical significative difference between the 2 groups. Nevertheless, it seems to be more heterogeneous in group G. However, we have not studied the visual field modifications after confluent PRP using up to 5,000 500 micron laser burns. Although there is a loss of retinal sensitivity after PRP, none of our patients complained of it. PRP seems to us to be the only treatment able to prevent the natural evolution of preproliferative or proliferative diabetic retinopathies.

- Abstract
Background: Groin ultrasonography (US) has been used as an adjunct to inguinal hernia diagnosis, but there is limited evidence as to whether its use affects surgical decision-making. The primary aim of this study was to examine whether groin US affects surgical management of inguinal hernia; the secondary goal was to estimate the frequency of groin US ordered before surgical consultation., Methods: We performed a retrospective chart review of 400 consecutive patients aged older than 18 years referred to 1 of 4 general surgeons in Calgary, Alberta, for inguinal hernia between January 2014 and January 2015. Bilateral groin examinations were entered as separate entries into the database. Outcomes assessed included the frequency of groin US examinations performed within 1 year before the general surgery consultation, presence of inguinal hernia on clinical examination (CE), presence of inguinal hernia on groin US, and whether the hernia proceeded to herniorrhaphy., Results: A total of 476 groins in the 400 patients (354 [88.5%] male; mean age 53.5 yr [standard deviation 15.2 yr]) were evaluated for a hernia during the study period. Groin US was performed before general surgery consultation in 336 cases (70.6%). Overall, 364 (76.5%) of the hernias were clinically palpable; of the 364, 220 (60.4%) had preconsultation US, even in the presence of a positive CE finding. Of the 112 groins that did not have a clinically palpable hernia, 103 (92.0%) underwent preconsultation US. Of the 476 groins, 315 (66.2%) underwent inguinal hernia repair: 310 (85.2%) of the 364 with clinically palpable hernias and 5 (4.8%) of the 103 with clinically negative findings but positive groin US findings. Surgical decision-making based on CE findings occurred in 390 cases (81.9%) overall, whereas surgery based on groin US findings alone occurred in 5 of 336 cases (1.5%)., Conclusion: Routine groin US was frequently performed before general surgery consultation, whether a hernia was detectable on clinical examination or not. Positive groin US results alone infrequently affected whether the patient proceeded to surgery. Clinical examination findings played a larger role in surgical decision-making than groin US results. Eliminating the practice of routine groin US may provide considerable health care cost savings., Competing Interests: Competing interests: Chad Ball is a coeditor-in-chief for CJS; he was not involved in the editorial decision-making process for this article.

- Abstract
Introduction: Decreasing the length of stay following bariatric surgery can reduce pressure on hospitals and surgical costs and increase patient satisfaction. We examine trends in length of hospital stay following bariatric surgery and in post-operative complications., Methods and Procedures: The 2015-2019 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was used to compile patients undergoing Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy. Patients were categorized into either early discharge (within one day of surgery) or late discharge, and patient and non-patient factors were compared between the two groups. A multivariable logistic regression was carried out to determine predictive factors for early discharge., Results: We evaluated 748,955 patients, with 399,918 (53%) being discharged early. Patients discharged early were younger and had fewer associated medical problems. The rate of early discharge increased between 2015 and 2019 (42.1% in 2015 vs 62.0% in 2019), while complication rates decreased or were unchanged. Multivariable analysis revealed lower ASA classification (OR 1.07; CI 1.06-1.09; p < 0.0001) and operative year (2019 vs. 2015 OR 2.26; CI 2.22-2.29; p < 0.0001) to be independently associated with early discharge. Several factors including undergoing RYGB (OR 0.44 CI 0.44-0.45; p < 0.0001), and dialysis dependence (OR 0.50; CI 0.45-0.55; p < 0.0001) among others, were associated with reduced early discharge likelihood., Conclusions: There is a trend in bariatric surgery towards the practice of early discharge, which is safe for patients. Further work is needed to develop a set of criteria to determine which patients are best suited for this practice., (© 2022.

- Abstract
Background: The effects of preoperative weight loss on bariatric surgery outcomes are still unclear, despite the practice being adopted by bariatric centers worldwide. Ongoing studies are needed for routine adoption of this practice given the multiple issues patients face with following difficult preoperative weight loss protocols., Objectives: The aim of this study was to characterize the prevalence of preoperative weight loss and evaluate its impact on outcomes following elective bariatric surgery., Setting: This retrospective study was conducted using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data registry from 2015-2018., Methods: All primary Roux-en-Y (RYGB) and sleeve gastrectomy (SG) procedures were included, whereas prior revisional surgeries and emergency surgeries were excluded. Cases were then divided into preoperative weight loss (PWL) and control cohorts. PWL was defined categorically if the highest 30-day preoperative weight was greater than the closest recorded weight before surgery. Primary outcomes included identifying the impact of PWL on postoperative complications. Multivariable logistic regression modelling was used to examine the influence of PWL on serious complications and mortality after adjusting for patient co-morbidities and procedure type., Results: A total of 548,597 patients were identified with the majority experiencing preoperative weight loss (n= 459,500; 83.8%). The PWL cohort was older (44.8 ± 12.0 versus 43.2 ± 11.9 yr), had a reduced body mass index (BMI) (45.0 ± 7.4 versus 46.1 ± 7.6 kg/m
2 ), and was more likely to be male (20.3% versus 18.7%). Patients with preoperative weight loss also were more likely to have metabolic co-morbidities including medication and insulin-dependent diabetes (27.0% versus 23.2%), hypertension (HTN) (48.9% versus 44.7%), dyslipidemia (DLP ) (24.6% versus 21.0%), and sleep apnea (39.6% versus 32.3%). No clinically significant differences were observed for operative length between cohorts (85.3 ± 46.9 min PWL versus 83.9 ± 46.2 min control). The protective benefit was found to be most significant for patients experiencing greatest weight loss with those experiencing a >10% PWL showing 30% decreased odds of leak (OR .68%; 95% CI [confidence interval] .56-.84; P < .0001) and a 40% decrease in odds of mortality versus those with no PWL (OR .60; 95% CI .39-.92; P = .02)., Conclusion: Preoperative weight loss before bariatric surgery is common, occurring in >80% of elective cases. Our findings suggest that preoperative weight loss is associated with improved odds of 30-day mortality and leaks but no differences in bleeds or overall serious complications. Additional prospective trials are needed to further evaluate the role of routine PWL in addition to ongoing development of tolerable preoperative weight-loss protocols., (Copyright © 2021 American Society for Bariatric Surgery.

- Abstract
Purpose: With the growing prevalence of bariatric procedures performed worldwide, it is important to understand the timing of postoperative complications following bariatric surgery and the differences which may exist between procedures., Methods: This retrospective study was conducted using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data registry from 2017 to 2018. All patients with primary elective Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) procedures were included. The primary outcome was to characterize the timing of postoperative complications for RYGB and SG., Results: A total of 316,314 patients were identified with 237,066 (74.9%) in the SG cohort and 79,248 (25.1%) in the RYGB cohort. Early complications included myocardial infarction (4.7 ± 6.4 days), cardiac arrest (6.4 ± 8.5 days), pneumonia (6.9 ± 6.9 days), progressive renal insufficiency (8.1 ± 8.1 days), and acute renal failure (8.2 ± 7.6 days). Late complications included Clostridioides difficile infection (11.3 ± 7.8 days), organ space infections (11.7 ± 7.9 days), deep incisional infections (12.4 ± 6.6 days), superficial incisional infections (13.2 ± 6.9 days), and urinary tract infections (14.0 ± 8.4 days). SG patients were more likely to be diagnosed later than RYGB patients with regard to superficial incisional infections (14.0 ± 7.4 days vs 12.5 ± 6.3 days; p = 0.002), organ space infections (12.6 ± 7.8 days vs 10.8 ± 7.9 days; p = 0.001), acute renal failure (9.3 ± 8.1 days vs 6.8 ± 6.8 days; p = 0.03), and pulmonary embolism (13.7 ± 7.5 days vs 11.3 ± 8.0 days; p = 0.003). No significant difference in timing was observed for any other complication by procedures., Conclusion: We demonstrate that significant differences in timing exist between complications and that these differences also vary by surgical procedure., (© 2021.

- Abstract
Background: Fibroepithelial lesions of the breast (FEL) are atypical lesions diagnosed on core-needle biopsy. The purpose of this study was to determine the rate at which FELs are upstaged to phyllodes tumor on excision, and to examine the clinical and radiological factors that may be predictive of upstaging., Methods: A retrospective review from the medical records of patients diagnosed with FEL on CNB at a single institution between 2010 and 2015 was performed. Patients diagnosed with benign or borderline phyllodes tumors were compared to those diagnosed with fibroadenoma., Results: Of 74 patients diagnosed with FEL, 48 underwent excision (64.9%). Of the 48 lesions excised, pathology revealed 30 fibroadenomas (62.5%), 14 benign phyllodes tumors (29.2%), and 4 borderline phyllodes tumor (8.3%). No malignant phyllodes tumors were identified. On preoperative ultrasound, heterogeneous echotexture (p = 0.03) and lack of internal vascularity (p = 0.03) were significantly associated with upstaging to phyllodes tumor., Conclusions: Surgical excision of FELs yield a pathological diagnosis of benign and borderline phyllodes tumor in 37.5% of cases. A high BIRADs score (≥4b), heterogeneous echotexture and lack of internal vascularity on ultrasound may help predict upstaging to phyllodes tumor., (Copyright © 2016 Elsevier Inc.

- Abstract
Purpose: To assesses the role of photodynamic therapy (PDT) with verteporfin in young patients with choroidal neovascularization (CNV) secondary to traumatic choroidal rupture., Design: Retrospective case series., Methods: Of 26 eyes with traumatic choroidal rupture followed since 1984 at the retina service of university hospitals, all eyes diagnosed with CNV and treated with PDT were included. Medical records including comprehensive eye examination, retinal photography, and intravenous fluorescein angiography (IVFA) were studied., Results: Five patients (mean age, 18 years) developed CNV and received an average of two PDT treatments. Three patients had improved visual acuity (VA), one remained stable, and one experienced visual loss. Final IVFA showed absence of leakage in four eyes and decreased leakage in the eye with decreased VA., Conclusions: In young patients, PDT may be a reasonable treatment for CNV secondary to choroidal rupture. No ocular or systemic PDT complications were encountered in this young population.

- Abstract
We examined ciprofloxacin levels in the aqueous humor, vitreous, or subretinal fluid in 40 patients undergoing cataract extraction, vitrectomy, or scleral buckling. Ciprofloxacin, 750 mg, was administered orally an average of 17 1/2 and 5 1/2 hours preoperatively. We obtained mean ciprofloxacin levels of 0.53 microgram/ml in aqueous humor, 0.51 microgram/ml in vitreous, and 0.71 microgram/ml in subretinal fluid. These vitreous levels exceed the minimum inhibitory concentration (MIC)90 of Staphylococcus epidermidis, Propionibacterium species, Pseudomonas aeruginosa, Proteus mirabilis, and Haemophilus influenzae, as well as the MIC70 of S. aureus and Bacillus cereus. Therefore, ciprofloxacin may have a role in the management and prevention of endophthalmitis.

- Abstract
Twelve diabetic patients presenting a preproliferative or proliferative retinopathy were the subjects of our study. We studied the modifications of the visual fields, analyzed by computerized perimetry, after panretinal photocoagulation (PRP). For every patient, two techniques of PRP were applied, one on each eye: C: conventional scattered treatment, G: cluster technique. Computerized perimetry was done within 10 days prior to PRP, and 4 to 8 weeks following it. We used the Octopus 500, programs 36 (0 to 30 degrees) and 44 (30 to 60 degrees). It appears that, before any treatment, there is a loss of retinal sensitivity excepted the more central zone. Concerning the loss of sensitivity, although the number of laser burns, is greater in group G, there is no statistical significative difference between the 2 groups. Nevertheless, it seems to be more heterogeneous in group G. However, we have not studied the visual field modifications after confluent PRP using up to 5,000 500 micron laser burns. Although there is a loss of retinal sensitivity after PRP, none of our patients complained of it. PRP seems to us to be the only treatment able to prevent the natural evolution of preproliferative or proliferative diabetic retinopathies.

- Abstract
Beneficial effect of cryopexy on 180 degrees to 360 degrees of avascular retina was demonstrated in 7 prematurely born infants (14 eyes) affected with advanced retinopathy of prematurity. Intravitreous new vessels were present in all eyes before treatment. The treatment of one eye was supplemented with scleral indentation. Only one of the treated eyes went on unfavourably with retrolental fibroplasia and consecutive loss of visual acuity. We believe that cryopexy, when administered promptly, when limited to the avascular zone, and when supplemented with scleral indentation in cases with important vitreous traction, is a valuable treatment with fewer risks than unchecked evolution for advanced cases of retinopathy of prematurity.
