Increased Risk of Periprosthetic Fractures and Revision Arthroplasty in Patients Undergoing Shoulder Arthroplasty With a History of Prior Fragility Fractures: A Matched Cohort Analysis.

INTRODUCTION: As rates of anatomic and reverse total shoulder arthroplasty (SA) continue to grow, an increase in the number of osteoporotic patients undergoing SA, including those who have sustained prior fragility fractures, is expected. The purpose of this study was to examine short-term, implant-related complication rates and secondary fragility fractures after SA in patients with and without a history of fragility fractures. METHODS: A propensity score-matched retrospective cohort study was done using the PearlDiver database to characterize the effect of antecedent fragility fractures in short-term complications after SA. Rates of revision SA, periprosthetic fractures, infection, and postoperative fragility fractures were evaluated using multivariate logistic regression analysis. Risks of these complications were also studied in patients with and without preoperative osteoporosis treatment. Statistical significance was set at P < 0.05. RESULTS: A total of 91,212 SA patients were identified, with 13,050 (14.3%) experiencing a fragility fracture within the 3 years before SA. Two years after SA, there were increased odds of periprosthetic fracture (odds ratio [OR] 2.24, 95% confidence interval [CI] 1.68 to 2.99), fragility fracture (OR 9.11, 95% CI 8.43 to 9.85), deep infection (OR 1.68, 95% CI 1.34 to 2.12), and all-cause revision SA (OR 1.68, 95% CI 1.44 to 1.96) within those patients who had experienced a fragility fracture within 3 years before their SA. Patients who were treated for osteoporosis with bisphosphonates and/or vitamin D supplementation before their SA had similar rates of postoperative periprosthetic fractures, fragility fractures, and all-cause revision SA to those who did not receive pharmacologic treatment. CONCLUSION: Sustaining a fragility fracture before SA portends substantial postoperative risk of periprosthetic fractures, infection, subsequent fragility fractures, and all-cause revision SA at the 2-year postoperative period. Pharmacotherapy did not markedly decrease the rate of these complications. These results are important for surgeons counseling patients who have experienced prior fragility fractures on the risks of SA.

[Reoperation treatment of persistent postoperative secondary hyperparathyroidism].

Objective:To evaluate the clinical effect of reoperation in persistent hyperparathyroidism （PHPT） patients after operation of parathyroidectomy combined with autotransplantation（PTX+AT） on secondary hyperparathyroidism （SHPT） . Methods:18 PHPT patients who treated with reoperation after PTX+AT were enrolled in this study during the period from Aug 2012 to Dec 2021 in the Department of Otolaryngology Head and Neck Surgery of Peking University Civil Aviation School of Clinical Medicine, Civil Aviation General Hospital. The remaining parathyroid glands were located by preoperative colour Doppler ultrasonography, radionuclide imaging, enhanced CT and MR imaging in the neck region . Based on the imaging findings, the remaining parathyroid glands were removed in situ, and the missed ectopic or extra parathyroid glands were resected with an extended surgical scope according to the parathyroid dissection method. The surgical effect was evaluated by the changes of clinical symptoms, the dynamic change of serum intact paramyroidhomone（i-PTH） between preoperative and postoperative periods and the surgical complications. Results:All the 18 patients accepted successful operation. 30 parathyroid glands were resected confirmed by postoperative pathology, including 16 in situ and 14 ectopic glands（5 in superior mediastinum, 4 in thymus, 2 in posterior mediastinum ,2 in thyroid glands, 1 in carotid sheath）.Osteoarthropathy and skin itching were significantly relieved or even disappeared at 6 h after surgery. The levels of serum i-PTH, calcium and phosphorus reached the standards and muscle weakness was significantly improved 1 week after surgery. 16 patients presented hypocalcemia and returned to normal after supplement of calcium. Hoarseness due to temporary injury of laryngeal nerve was found in 6 cases. No serious complications or death occurred after the operation.There was no recurrence after 1 year follow-up. Conclusion:Reoperation is the first choice for SHPT patients complicated with persistent hyperparathyroidism. Multiple imaging examinations are used to locate the residual parathyroid, especially the ectopic gland. Expanded surgical scope is applied to resect all the residual parathyroid glands（ectopic, in situ and concealed parathyroid） according to the concept of dissection parathyroidectomy. The surgery is effective and safe. Patients'quality of life and long-term survival rate is improved.

Decreasing trends in reintervention and readmission after endovascular aneurysm repair in a multiregional implant registry.

OBJECTIVE: As endovascular aortic aneurysm repair (EVAR) matures into its third decade, measures such as long-term reintervention and readmission have become a focus of quality improvement efforts. Within a large United States integrated health care system, we describe time trends in the rates of long-term reinterventions utilization measures. METHODS: Data from a United States multiregional EVAR registry was used to perform a descriptive study of 3891 adults who underwent conventional infrarenal EVAR for infrarenal abdominal aortic aneurysm between 2010 and 2019. Three-year follow-up was 96.7%. Outcomes included 1-, 3-, and 5-year graft revision (defined as a procedure involving placement of a new endograft component), secondary interventions (defined as a procedure necessary for maintenance of EVAR integrity [eg, coil embolization and balloon angioplasty/stenting]), conversion to open, interventions for type II endoleaks alone, and 90-day readmission. Crude cause-specific reintervention probabilities were calculated by operative year using the Aalen-Johansen estimator, with death as a competing risk and December 31, 2020 as the study end date. RESULTS: Excluding interventions for type II endoleak alone, 1-year secondary intervention incidence decreased from 5.9% for EVARs in 2010 to 2.0% in 2019 (P < .001) and 3-year incidence decreased from 7.2% to 3.6% from 2010 to 2017 (P = .03). The 3-year incidences of graft revision (mean incidence, 3.4%) and conversion to open remained fairly stable (mean incidence, 0.6%) over time. The 3-year incidence of interventions for type II endoleak alone also decreased from 3.4% in 2010 to 0.7% in 2017 (P = .01). Ninety-day readmission rates decreased from 19.3% for index EVAR in 2010 to 9.2% in 2019 (P = .03). CONCLUSIONS: Comprehensive data from a multiregional health care system demonstrates decreasing long-term secondary intervention and readmission rates over time in patients undergoing EVAR. These trends are not explained by evolving management of type II endoleaks and suggest improving graft durability, patient selection, or surgical technique. Further study is needed to define implant and anatomic predictors of different types of long-term reintervention.

Radial head arthroplasty: a descriptive study of 970 patients in an integrated health care system.

BACKGROUND: Radial head arthroplasty (RHA) is commonly performed for isolated comminuted radial head fractures and in conjunction with traumatic elbow instability. However, there is a paucity of literature directly describing the characteristics and outcomes of patients who undergo RHA in a community-based setting. We describe a cohort of 970 RHA performed in the California regions of a US integrated health care system over a 9-year period. Patient demographics, implant selection, 90-day acute postoperative events, and cumulative reoperation/revision rates are included. METHODS: Patients aged ≥18 years who underwent primary RHA were identified (2009-2017). Patient characteristics and demographics, including age, body mass index, gender, diabetes status, American Society of Anesthesiologists (ASA) classification, primary diagnosis, and concomitant procedures were described. Crude cumulative revision and reoperation probabilities were calculated as 1 minus the Kaplan-Meier estimator, with follow-up time calculated as the time from the index RHA to revision/reoperation date for those with the outcome of interest and time from index RHA to censoring date (eg, date of death, health care termination, study end date [March 31, 2018]) for those without the outcome. Ninety-day postoperative incidence of emergency department (ED) visit, readmission, and mortality was calculated as the number of patients with the event of interest over the number of patients at risk. RESULTS: A total of 970 patients underwent primary unilateral RHA by 205 surgeons during the study period. Annual procedure volume increased from 53 procedures in 2009 to 157 procedures in 2017. More patients were female, without diabetes, and had an ASA classification of 1 or 2. Fracture was the predominant indication for RHA (98.4%) and more than half (54.3%) had concomitant procedures performed. Most implants were press fit (63.2%) over loose fit, and >90% were monopolar. Three-year cumulative revision and reoperation probabilities following RHA were 6.5% (95% confidence interval [CI] = 5.0%-8.5%) and 8.2% (95% CI = 6.5%-10.3%), respectively. Revisions and reoperations tended to occur within the first postoperative year. Of the 970 RHA patients, 83 (8.5%) had a 90-day ED visit, 58 (6.0%) had a 90-day readmission, and 1 (0.1%) died within a 90-day postoperative period. CONCLUSION: This large cohort of RHA patients provides information about the practice of RHA at large and in the community. Surgeons are performing more RHA over time and choosing press fit stems more often. Revisions and reoperations tended to occur early. Readmission and ED visits were low but not negligible, with pain being the most common reason for ED visit.

Direct Vision, Transfascial (DVT) Approach to Submuscular Reservoir Placement in Patients Undergoing Multicomponent Penile Implant Surgery Following Prior Pelvic Surgery or Radiation Therapy.

BACKGROUND: Submuscular reservoir placement has fulfilled a critical need for patients desiring multicomponent penile implants following pelvic surgery and radiation therapy. Passage of the reservoir through the inguinal canal into the submuscular space is often challenging and carries the risk of the reservoir being placed unknowingly outside of the targeted space. AIM: To evaluate the safety and accuracy of a direct vision, transfascial (DVT) approach to submuscular reservoir placement. METHODS: We retrospectively reviewed outcomes for consecutive patients undergoing DVT submuscular reservoir placement abstracted from a large IRB-approved database at our institution. Postimplant cross-sectional imaging performed on many of these patients was used to ascertain the final location of the reservoir. OUTCOMES: Outcome measures included the perioperative and intermediate-term safety and complications of the procedure. Postimplant imaging ascertained the accuracy in providing patients with a submuscular reservoir. RESULTS: There were 107 DVT submuscular reservoirs placed in 100 consecutive patients. No intraoperative complications occurred, there were no postoperative rectus hematomas, and there were 4 (3.7%) postoperative infections. With a mean follow up of 17.5 +/- 20.5 months there was one reservoir herniation, one patient had autoinflation, and one patient required repositioning of a high riding pump. There were 4 mechanical malfunctions requiring revision at a median of 74 months (range: 69-108 months.) following implant placement. Of the 43 patients who underwent imaging: 34 (79%) reservoirs were accurately positioned, 5 (12%) were in the lateral abdominal wall, 1(2%) was in the retroperitoneum, and 3 (7%) were intraperitoneal. Intraperitoneal reservoirs occurred exclusively in postcystectomy patients. CLINICAL IMPLICATIONS: The DVT approach is technically safe, although a slightly higher than expected infection risk was noted. It provides accurate reservoir placement for the majority of imaged patients. Postcystectomy patients have a risk of insidious intraperitoneal reservoir placement. Preoperative counseling should mention this and postimplant imaging may be considered for some of these patients. Imaging may also helpful prior to future revision surgery in order to identify and remove insidious intraperitoneal reservoirs. STRENGTHS AND LIMITATIONS: We investigated 100 patients, almost half underwent cross sectional imaging. Weaknesses include the retrospective nature of this single-institutional study, which may not have similar outcomes at other centers. CONCLUSION: DVT submuscular reservoir placement is safe following pelvic surgery and radiation therapy. Despite careful and deliberate surgical technique imaging found that approximately 20% of reservoirs are not in their expected location. Intraperitoneal reservoirs are of concern, particularly in postcystectomy patients. Kava BR, Levine A, Hauser N, et al.

Single-stage revision of MRSA orthopedic device-related infection in sheep with an antibiotic-loaded hydrogel.

Local antimicrobial therapy is an integral aspect of treating orthopedic device-related infection (ODRI), which is conventionally administered via polymethyl-methacrylate (PMMA) bone cement. PMMA, however, is limited by a suboptimal antibiotic release profile and a lack of biodegradability. In this study, we compare the efficacy of PMMA versus an antibiotic-loaded hydrogel in a single-stage revision for chronic methicillin-resistant Staphylococcus aureus (MRSA) ODRI in sheep. Antibiofilm activity of the antibiotic combination (gentamicin and vancomycin) was determined in vitro. Swiss alpine sheep underwent a single-stage revision of a tibial intramedullary nail with MRSA infection. Local gentamicin and vancomycin therapy was delivered via hydrogel or PMMA (n = 5 per group), in conjunction with systemic antibiotic therapy. In vivo observations included: local antibiotic tissue concentration, renal and liver function tests, and quantitative microbiology on tissues and hardware post-mortem. There was a nonsignificant reduction in biofilm with an increasing antibiotic concentration in vitro (p = 0.12), confirming the antibiotic tolerance of the MRSA biofilm. In the in vivo study, four out of five sheep from each treatment group were culture-negative. Antibiotic delivery via hydrogel resulted in 10-100 times greater local concentrations for the first 2-3 days compared with PMMA and were comparable thereafter. Systemic concentrations of gentamicin were minimal or undetectable in both groups, while renal and liver function tests were within normal limits. This study shows that a single-stage revision with hydrogel or PMMA is equally effective, although the hydrogel offers certain practical benefits over PMMA, which make it an attractive proposition for clinical use.

Evaluation of repeat cytoreductive surgery and heated intraperitoneal chemotherapy for patients with recurrent peritoneal carcinomatosis from appendiceal and colorectal cancers: a multicentre Canadian study

Background: Peritoneal recurrences after cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) for appendiceal and colorectal cancers are frequent. This study aimed to evaluate the safety, technical feasibility and perioperative and long-term outcomes of repeat CRS/HIPEC in patients with recurrent peritoneal carcinomatosis of colorectal and appendiceal origin. Methods: Data were collected from patients treated from 2000 to 2016 for recurrent peritoneal carcinomatosis from appendiceal or colorectal cancer with CRS/HIPEC at 2 specialist centres. Data on demographics, procedure details, morbidity and survival were recorded. Analyses compared the iterations of CRS/HIPEC to assess the safety and effectiveness of repeat surgery. Results: Of all patients who underwent CRS/HIPEC in the 2 centres, 37 patients underwent a repeat procedure. Operative time was similar for the first and second surgeries (412.1 v. 412.5 min, p = 0.74) but patients had a significantly lower peritoneal carcinoma index score with the second surgery (21.8 in the first iteration v. 9.53 in the second iteration, p < 0.001) and significantly less blood loss (1762 mL in the first iteration v. 790 mL in the second iteration, p = 0.001). There was a nonsignificant decrease in grade III­IV complications and there was no 30-day mortality associated with repeat procedures. For patients with colorectal cancer, median disease-free survival was 9.6 months and median overall survival was 40 months. For patients with appendiceal cancer, median disease-free survival was 15 months and overall survival was 64.4 months. Conclusion: Repeat CRS/HIPEC procedures for recurrent appendiceal and colorectal peritoneal carcinomatosis are safe in well-selected patients, without increased morbidity or mortality, and they are associated with significant long-term survival, particularly for patients with appendiceal cancers. These results support the use of repeat CRS/HIPEC in these patients.

Contexte: Les récurrences péritonéales après une chirurgie cytoréductrice (CCR) et une chimiothérapie hyperthermique intrapéritonéale (CHIP) pour les cancers de l'appendice et colorectaux sont fréquentes. Cette étude visait à évaluer l'innocuité, la faisabilité technique et les résultats périopératoires et à long terme d'une reprise de CCR/CHIP chez les patients qui présentent une récurrence de carcinomatose péritonéale ayant son origine au niveau colorectal ou de l'appendice. Méthodes: Des données ont été recueillies sur des patients traités entre 2000 et 2016 pour une récurrence de carcinomatose péritonéale ayant son origine au niveau colorectal ou de l'appendice par CCR/CHIP dans 2 centres spécialisés. On a tenu compte des données démographiques, des détails des interventions, ainsi que de la morbidité et de la survie. Des analyses ont permis de comparer les premières et deuxièmes CCR/CHIP pour évaluer l'innocuité et l'efficacité des chirurgies répétées. Résultats: De tous les patients soumis à des CCR/CHIP dans les 2 centres, 37 ont subi l'intervention de nouveau. Le temps opératoire a été similaire pour les premières et les deuxièmes chirurgies (412,1 c. 412,5 min, p = 0,74), mais les patients présentaient un score de carcinomatose péritonéale beaucoup plus bas lors de la deuxième chirurgie (21,8 pour la première intervention c. 9,53 pour la seconde, p < 0,001) et des pertes sanguines significativement moindres (1762 mL pour la première intervention c. 790 mL pour la seconde, p = 0,001). On a noté une diminution non significative des complications de grades III­IV et on n'a déploré aucune mortalité à 30 jours en lien avec la reprise de l'intervention. Pour les patients atteints d'un cancer colorectal, la survie médiane sans maladie a été de 9,6 mois et la survie médiane globale a été de 40 mois. Pour les patients atteints d'un cancer de l'appendice, la survie médiane sans maladie a été de 15 mois et la survie médiane globale a été de 64,4 mois. Conclusion: La reprise des CCR/CHIP pour les récurrences de carcinomatose péritonéale ayant leur origine au niveau colorectal ou de l'appendice est sécuritaire chez les patients soigneusement sélectionnés, sans accroissement de la morbidité ou de la mortalité, et elles sont associées à une survie à long terme significative, particulièrement chez les patients ayant un cancer de l'appendice. Ces résultats appuient la reprise des CCR/CHIP chez ces patients.

Anticoagulation in Revision Total Joint Arthroplasty: A Retrospective Review of 1917 Cases.

Although several studies now support the use of aspirin for venous thromboembolism (VTE) prophylaxis in primary total hip arthroplasty (THA) and total knee arthroplasty (TKA), the optimal chemoprophylactic agent in revision THA and TKA is not clear. The purpose of this study was to determine if the type of chemoprophylaxis has an effect on the VTE rate in patients undergoing revision total joint arthroplasty (TJA). The second aim was to compare differences in rates of wound drainage in primary and revision TJA stratified by the postoperative chemoprophylaxis used. The authors retrospectively reviewed 1917 consecutive patients undergoing primary and revision TJA. Individual records were reviewed for patient demographics, medical comorbidities, type of chemoprophylaxis, VTE risk factors, intraoperative data, and postoperative complications. Outcomes, including VTE rate and wound complications, were compared between types of anticoagulant therapy used postoperatively. Of the 1917 patients, there were 742 (38.7%) primary TKAs, 326 (17%) revision TKAs, 608 (31.7%) primary THAs, and 241 (12.6%) revision THAs. The most common prophylactic agent used was rivaroxaban (40.6%), followed by warfarin (28.5%) and aspirin (27.6%). Type of chemoprophylaxis was not associated with postoperative VTE or wound drainage (P>.05). Although revision surgery was an independent risk factor for wound drainage (odds ratio, 3.201; 95% confidence interval, 1.594-6.426; P=.001), it was not a risk factor for VTE (odds ratio, 1.847; 95% confidence interval, 0.423-8.053; P=.414). Revision arthroplasty alone was not associated with an increased rate of VTE. Aspirin is as effective as other chemoprophylactic agents without the increased risk of bleeding in low-risk patients.

Recovery Kinetics: Comparison of Patients Undergoing Primary or Revision Procedures for Adult Cervical Deformity Using a Novel Area Under the Curve Methodology.

BACKGROUND: Limited data are available to objectively define what constitutes a "good" versus a "bad" recovery for operative cervical deformity (CD) patients. Furthermore, the recovery patterns of primary versus revision procedures for CD is poorly understood. OBJECTIVE: To define and compare the recovery profiles of CD patients undergoing primary or revision procedures, utilizing a novel area-under-the-curve normalization methodology. METHODS: CD patients undergoing primary or revision surgery with baseline to 1-yr health-related quality of life (HRQL) scores were included. Clinical symptoms and HRQL were compared among groups (primary/revision). Normalized HRQL scores at baseline and follow-up intervals (3M, 6M, 1Y) were generated. Normalized HRQLs were plotted and area under the curve was calculated, generating one number describing overall recovery (Integrated Health State). Subanalysis identified recovery patterns through 2-yr follow-up. RESULTS: Eighty-three patients were included (45 primary, 38 revision). Age (61.3 vs 61.9), gender (F: 66.7% vs 63.2%), body mass index (27.7 vs 29.3), Charlson Comorbidity Index, frailty, and osteoporosis (20% vs 13.2%) were similar between groups (P > .05). Primary patients were more preoperatively neurologically symptomatic (55.6% vs 31.6%), less sagittally malaligned (cervical sagittal vertical axis [cSVA]: 32.6 vs 46.6; T1 slope: 28.8 vs 36.8), underwent more anterior-only approaches (28.9% vs 7.9%), and less posterior-only approaches (37.8% vs 60.5%), all P < .05. Combined approaches, decompressions, osteotomies, and construct length were similar between groups (P > .05). Revisions had longer op-times (438.0 vs 734.4 min, P = .008). Following surgery, complication rate was similar between groups (66.6% vs 65.8%, P = .569). Revision patients remained more malaligned (cSVA, TS-CL; P < .05) than primary patients until 1-yr follow-up (P > .05). Normalized HRQLs determined primary patients to exhibit less neck pain (numeric rating scale [NRS]) and myelopathy (modified Japanese Orthopaedic Association) symptoms through 1-yr follow-up compared to revision patients (P < .05). These differences subsided when following patients through 2 yr (P > .05). Despite similar 2-yr HRQL outcomes, revision patients exhibited worse neck pain (NRS) Integrated Health State recovery (P < .05). CONCLUSION: Despite both primary and revision patients exhibiting similar HRQL outcomes at final follow-up, revision patients were in a greater state of postoperative neck pain for a greater amount of time.

Hyperbaric oxygen therapy as adjuvant for treating wound complications after extensive resection for vulvar malignancy.

INTRODUCTION: Necrosis, wound breakdown, and infection represent major complications associated with radical vulvectomy. We aimed to analyze the feasibility of hyperbaric oxygen (HBO2) therapy as an adjunctive treatment for such complications. METHODS: We performed a retrospective analysis of the medical records, clinical charts, and operative records of vulvar cancer patients who underwent hyperbaric oxygen therapy after extensive surgical resection in our institute between 2012 and 2016, with a comparison of the clinical outcomes of patients with similar surgical procedures andsevere wound complications who did not undergo HBO2. RESULTS: A total of 16 patients were included in the study. In the subgroup treated with HBO2, seven patients were identified. Two patients had primary surgery, while five had recurrent surgery (of these, two had previously undergone radiation therapy). Six patients received reconstructive flaps (five myocutaneous and onefasciocutaneous), while one patient had primary suture. Dehiscence, ischemia and necrosis were estimated to cover 30%-80% of the surgical surface area. Surgical debridement was performed in six patients. Daily 90-minute sessions in the hyperbaric chamber were performed at a pressure of 2.2 atmospheres absolute, with partial oxygen pressure of 1672 mbar. Infection control and satisfactory healing were achieved using 10-61 sessions. All patients in the subgroup who did not receive HBO2 required surgical debridement due to partial or near-total flap necrosis, with two reconstructive interventions required. CONCLUSIONS: Hyperbaric oxygen therapy was an efficient adjuvant for wound healing and infection control in managing wound complications after extensive vulvar resections.

Effect of Low-level Laser Therapy on Postoperative Pain after Root Canal Retreatment: A Preliminary Placebo-controlled, Triple-blind, Randomized Clinical Trial.

INTRODUCTION: Low-level laser therapy (LLLT) is a practical, nonpharmacologic technique for reducing pain. This study evaluated the effect of LLLT on postoperative pain after root canal retreatment (RCR). METHODS: This study enrolled patients (N = 36) who required root canal retreatment (RCR) on mandibular molar teeth, presented with periapical lesions with periapical index scores of 2 or 3, and had a pain visual analog scale (VAS) <50 and a percussion pain VAS <50. The participants were divided into 2 groups: (1) patients scheduled for RCR followed by LLLT (n = 18) and (2) patients scheduled for RCR followed by a mock LLLT (placebo) (n = 18). Postoperative pain was assessed using the VAS. Data were collected and statistically analyzed with the chi-square test, the independent sample t test, and the Mann-Whitney U test (P = .05). RESULTS: On the first 4 days, postoperative pain significantly reduced in the LLLT group compared with the placebo group (P < .05). However, no statistically significant differences in postoperative pain were found between the 2 groups after 5 and 7 days (P > .05). The number of patients who needed analgesics was lower in the LLLT group than in the placebo group (P < .05). No patient reported pain during LLLT application. CONCLUSIONS: LLLT may reduce postoperative pain after RCR of mandibular molars.

Koebner phenomenon induced by failed revisional orthopedic surgery but remitted with bone union: A case report.

RATIONALE: Trauma or surgical incision might cause Koebner phenomenon (KP) in patients with cutaneous diseases, but seldom studies reported KP induced by repeated orthopedic surgery. PATIENT CONCERNS: The 22-year-old man did not have any prior histories of cutaneous diseases. Two months after the revision surgery for nonunion of the left femoral shaft fracture, KP was noted by psoriasis presented at the surgical scar, left thigh, scalp, and trunk. Phototherapy and topical treatments were prescribed but the effect was limited. DIAGNOSIS: KP induced by failed revisional orthopedic surgery. INTERVENTIONS: Because of implant failure, he underwent the second revision surgery, which was performed on the previous scar surrounded and covered by psoriatic plaques. OUTCOMES: After the second revision surgery successfully corrected the orthopedic problem, the psoriatic lesion remitted along with the bone union. LESSONS: In a patient having KP, to perform an operation on psoriatic lesion sites was safe and the surgical wound could heal well. The most important to treat KP induced by orthopedic surgery might be the underlying bone stability.

The T-plasty as therapy for recurrent bladder neck stenosis: success rate, functional outcome, and patient satisfaction.

PURPOSE: To determine success rate (SR), functional outcome, and patient satisfaction of a modified YV-plasty for reconstruction of the bladder neck in case of recurrent bladder neck stenosis (BNS) after transurethral surgery of the prostate: the T-plasty. PATIENTS AND METHODS: We identified all patients who underwent T-plasty at our center between December 2008 and July 2016. Patients' charts were reviewed. Patients were queried by telephone and by mail at time of follow-up (FU). Primary endpoint was SR. Secondary endpoints were complications, continence, satisfaction, and changes in quality of life measured by validated questionnaires. RESULTS: Thirty patients underwent the T-plasty. Median age at surgery was 69 (IQR 62-73) years. Most patients had BNS due to TUR-P [n = 25 (83.3%)]. No severe blood loss or severe complications occurred perioperatively. Median FU was 45 (IQR 18-64) months. Three patients were lost to FU. Success rate was 100%. Compared to pre-OP Q max, mean Q max post-OP improved significantly [pre-OP 6.79 (SD ± 4.76) ml/s vs post-OP was 24.42 (SD ± 12.61) ml/s; (t(5) = 4.12, p = 0.009)]. Mean post-void residual urine decreased significantly [pre-OP 140.77 (SD ± 105.41) ml vs post-OP 14.5 (SD ± 22.42) ml; (t(9) = -3.86, p = 0.004)]. One patient developed a de-novo-incontinence post-OP. Mean ICIQ-SF Score was 1.2 (SD ± 2.27). 88.5% of patients were pleased or delighted by surgery. 75% of patients claimed their quality of life has been (strongly) improved. CONCLUSIONS: The T-plasty is a valuable option as treatment of recurrent BNS. SR, rates of continence, and high patient satisfaction are very encouraging.

Quality of life following hip fractures: results from the Norwegian hip fracture register.

BACKGROUND: Patient-reported health-related quality of life is an important outcome measure when assessing the quality of hip fracture surgery. The frequently used EQ-5D index score has unfortunately important limitations. One alternative can be to assess the distribution of each of the five dimensions of the patients' descriptive health profile. The objective of this paper was to investigate health-related quality of life (HRQoL) after hip fractures. METHODS: Data from hip fracture operations from 2005 through 2012 were obtained from The Norwegian Hip Fracture Register. Patient reported HRQoL, (EQ-5D-3L) was collected from patients preoperatively and at four and twelve months postoperatively n = 10325. At each follow-up the distribution of the EQ-5D-3L and mean pain VAS was calculated. RESULTS: Generally, a higher proportion of patients reported problems in all 5 dimensions of the EQ-5D-3L at all follow-ups compared to preoperative. Also a high proportion of patients with no preoperative problems reported problems after surgery; At 4 and 12 months follow-ups 71 % and 58 % of the patients reported walking problems, and 65 % and 59 % of the patients reported pain respectively. Patients with femoral neck fractures and the youngest patients (age < 70 years) reported least problems both preoperatively and at all follow-ups. CONCLUSIONS: A hip fracture has a dramatic impact on the patients' HRQoL, and the deterioration in HRQoL sustained also one year after the fracture. Separate use of the descriptive profile of the EQ-5D is informative when assessing quality of life after hip fracture surgery.

Possible digoxin toxicity associated with concomitant ciprofloxacin therapy.

CASE (DESCRIPTION): A 27 year old female with a complex history of congenital heart disease, cardiac surgery, heart failure, and arrhythmias was admitted for a Pseudomonas aeruginosa sternal wound infection and treated with intravenous antibiotics. After discharge and completion of an outpatient course of intravenous antibiotics, suppressive antibiotic therapy with ciprofloxacin was initiated. She presented to clinic with nausea and anorexia within a few days of addition of ciprofloxacin to her current regimen of medications, which included digoxin. The digoxin was discontinued, with all other medications remaining the same, and the symptoms resolved in 48 h. The dose of digoxin was restarted at 50 % of the previous dose with no further complications. The proposed cause of the nausea and anorexia was digoxin toxicity secondary to a drug-drug interaction with ciprofloxacin. CONCLUSION: Patients receiving ciprofloxacin and digoxin should be monitored closely for the risk of digoxin toxicity.

Bleeding tendency in an adolescent with chronic small bowel obstruction.

We report a case of fat-soluble vitamin deficiency in a 14-year old boy who had chronic duodenal obstruction. He presented with periodic unexplained bleeding tendency. The laboratory results showed positive fat globules in stool and prolonged prothrombin time. His further investigation revealed low plasma vitamin A and undetectable plasma vitamin E. After parenteral vitamin K and oral vitamin A and E supplement, these abnormalities resolved although he still had absent knee jerk. We propose that fat malabsorption and fat-soluble vitamin deficiency can occur after prolonged duodenal obstruction that induce bacterial overgrowth following by bile acid deconjugation. Despite very few case reports, screening for fat malabsorption and fat-soluble vitamin deficiency might be warranted in patients with chronic small bowel obstruction.

A report of paraparesis following spinal cord stimulator trial, implantation and revision.

BACKGROUND: Spinal cord injury has been reported as a rare complication of spinal cord stimulation (SCS). A review of the literature shows a very low incidence of neurological injury after spinal cord stimulation trial, implantation and revision. The most common reported complication is equipment failure without neurologic injury. The incidence of spinal cord injury after SCS trial, implantation and revision is unknown. There have been limited reports of neurologic injury secondary to dural puncture, infection, cord contusion, actual needle penetration of the spinal cord and epidural hematoma. STUDY DESIGN: A report of 4 cases. OBJECTIVE: To report 4 occurrences of neurological complication after spinal cord stimulator implantation. METHODS: Four patients are presented who were admitted to an acute spinal cord rehabilitation hospital over a 4-month period. All 4 patients presented with paraparesis after spinal cord stimulator trial or implantation. One of the injuries is secondary to cord contusion, while the other 3 are secondary to cord compressions. Two of these compressions are due to epidural hematomas and one secondary to implantation in the setting of broad based thoracic disc herniations. The clinical cases are presented as well as a review of the literature. RESULTS: All 4 patients had the electrodes and neurostimulators successfully removed prior to their acute rehabilitation admissions. At discharge from acute inpatient rehabilitation, one patient continued to experience complete paraplegia, 2 patients had incomplete paraparesis and one had fully recovered all of his neurologic function. CONCLUSION: SCS is considered a safe procedure. Further investigation into the true incidence of neurologic injury after SCS is warranted.

Intra-articular lateral femoral condyle fracture following an ACL revision reconstruction.

Lateral femoral condyle fractures following an ACL reconstruction are rare. To our knowledge, this is the first case report of a lateral femoral condyle fracture following a revision ACL reconstruction. The patient's fracture was intra-articular, had a significant amount of soft tissue damage, and was further complicated by a large defect involving the bone tunnel from the ACL revision reconstruction. The patient was treated with an open reduction and internal fixation and recovered well.

Conversion of failed vertical banded gastroplasty to biliopancreatic diversion, a wise option.

BACKGROUND: Reoperations due to failures constitute an essential but challenging part of bariatric surgery practice today. The aim of this study was to evaluate the perioperative safety, efficacy, and postoperative quality of life in patients with biliopancreatic diversion (BPD), after failed vertical banded gastroplasty (VBG). METHODS: Twelve patients after failed or complicated VBG, eight females and four males, median age 45 years (range 39-52), median body mass index (BMI) 46.39 kg/m2 (range 25.89-69.37), who underwent conversion to BPD, were studied. RESULTS: Ten patients due to weight regain and two patients because of severe stenosis of the gastric pouch outlet were submitted in conversion to BPD. In eight (66.6%) patients the primary VBG had been followed by at least one revisional operation due to inadequate weight loss. The 10 patients after failed VBG, reached the lowest BMI recorded after VBG in just a year after BPD (p=0.721 for the comparison between the two time points). The two patients with stomal stenosis regained weight in the first six postoperative months and remain stable since then. Regarding safety, one major perioperative complication (gastrojejunostomy stenosis) occurred. At a median follow-up of 21 months (range 12-30) six complications have been documented, including a case of incisional hernia, four cases of pouch gastritis and a case of intractable iron-deficiency anemia. CONCLUSION: Our early results indicate that conversion of failed VBG to BPD is highly effective with acceptable morbidity. Our data show that the effect on weight is strongly dependent on the indication for the conversion. Conversion to BPD, in such a group of patients, is a wise alternative, since it may reduce operative risks.

Retreatment of full-thickness macular hole: predictive value of optical coherence tomography.

AIM: To determine whether the efficacy of re-operation for idiopathic full-thickness macular hole (FTMH) remaining open after initial surgery with internal limiting membrane (ILM) peeling is correlated with macular hole configuration as determined by optical coherence tomography (OCT), macular hole size, macular hole duration before the first operation, or type of tamponade (gas or silicone oil). METHODS: A retrospective consecutive interventional case series of 28 patients (28 eyes) with a persisting macular hole after vitrectomy, ILM peel, and gas tamponade. 28 patients underwent repeat surgery involving vitrectomy and gas (n = 15) or silicone oil tamponade (n = 12) or no tamponade (n = 1). Autologous platelet concentrate (n = 22), autologous whole blood (n = 1), or no adjuvant (n = 5) was used. Preoperative OCT was undertaken in all eyes. The main outcome measures were anatomical closure and improvement of best-corrected visual acuity (BCVA). RESULTS: Anatomical closure was achieved in 19 of 28 eyes (68%). BCVA improved in 12 eyes, remained unchanged in nine, and worsened in seven. BCVA improved in 11 of 19 eyes with anatomical closure, and in one of eight eyes without closure. Anatomical closure and improvement of BCVA correlated with preoperative macular hole configuration on OCT, with higher rates of closure (18 of 20 eyes versus one of eight eyes, p = 0.001) and greater improvement of BCVA (p = 0.048) in eyes with a cuff of subretinal fluid at the break margin. Macular hole size, type of tamponade, macular hole duration before the first operation, or preoperative BCVA did not significantly correlate with visual or anatomical outcome. CONCLUSION: Macular hole configuration seems to be a strong prognostic indicator of anatomical closure and may help identify those patients most likely to benefit from re-operation.
