Pneumonitis After Concurrent Chemoradiation and Immune Checkpoint Inhibition in Patients with Locally Advanced Non-small Cell Lung Cancer.

AIMS: Pneumonitis is a common and potentially deadly complication of combined chemoradiation and immune checkpoint inhibition (CRT-ICI) in patients with locally advanced non-small cell lung cancer (LA-NSCLC). In this study we sought to identify the risk factors for pneumonitis with CRT-ICI therapy in LA-NSCLC cases and determine its impact on survival. MATERIALS AND METHODS: We conducted a retrospective chart review of 140 patients with LA-NSCLC who underwent curative-intent CRT-ICI with durvalumab between 2018 and 2021. Pneumonitis was diagnosed by a multidisciplinary team of clinical experts. We used multivariable cause-specific hazard models to identify risk factors associated with grade ≥2 pneumonitis. We constructed multivariable Cox proportional hazard models to investigate the impact of pneumonitis on all-cause mortality. RESULTS: The median age of the cohort was 67 years; most patients were current or former smokers (86%). The cumulative incidence of grade ≥2 pneumonitis was 23%. Among survivors, 25/28 patients had persistent parenchymal scarring. In multivariable analyses, the mean lung dose (hazard ratio 1.14 per Gy, 95% confidence interval 1.03-1.25) and interstitial lung disease (hazard ratio 3.8, 95% confidence interval 1.3-11.0) increased the risk for pneumonitis. In adjusted models, grade ≥2 pneumonitis (hazard ratio 2.5, 95% confidence interval 1.0-6.2, P = 0.049) and high-grade (≥3) pneumonitis (hazard ratio 8.3, 95% confidence interval 3.0-23.0, P < 0.001) were associated with higher all-cause mortality. CONCLUSIONS: Risk factors for pneumonitis in LA-NSCLC patients undergoing CRT-ICI include the mean radiation dose to the lung and pre-treatment interstitial lung disease. Although most cases are not fatal, pneumonitis in this setting is associated with markedly increased mortality.

Ten-year survival rate of 89% after distal femoral osteotomy surgery for lateral compartment osteoarthritis of the knee.

PURPOSE: The purpose of this study was to assess the accuracy, safety, and survival of distal femoral osteotomy (DFO) surgery for lateral compartment OA of the knee. METHODS: A retrospective cohort study was conducted at a single UK centre, using prospectively collected data over an 8-year period (2009-2017). All patients had pre-operative radiographic analysis and digital planning of their deformity correction in addition to post-operative analysis of the achieved correction and yearly face-to-face follow-up. Complications (defined as an undesirable medical or surgical event as a direct result of the operation), reoperations, and failure (defined as conversion to arthroplasty or revision) were recorded. RESULTS: From a total of 83 patients, 81 patients undergoing 86 primary DFOs were included in this study, with a mean follow-up of 99 months (SD 27 months). The mean pre-operative percentage Mikulicz point was 78.7% (SD 19.1%) and post-operative 35.9% (SD 14.8%). The mean accuracy of correction (intended correction - achieved correction) was an 8.2% overcorrection (SD 13.7%). The complication rate was 4.7%. Using Kaplan-Meier analysis, the mean survival was 113 months (95% CI 106-120) with the probability of surviving 10 years 89%. CONCLUSION: DFO for valgus alignment and lateral compartment arthritis is associated with low complications, long-term joint preservation, and the prevention of arthroplasty surgery. However, the accuracy of correction still requires improvement in intra-operative technique. LEVEL OF EVIDENCE: IV.

Treatment of focal chondral lesions in the knee using a synthetic scaffold plug: Long-term clinical and radiological results.

The management of symptomatic articular cartilage lesions, especially in the young, fit individual remains an area of considerable controversy. Articular cartilage repair or reconstruction techniques may offer these patients alternatives to arthroplasty. The TruFit™ plug is a synthetic biphasic polymer scaffold that is designed for implantation at the site of a focal chondral defect. The aim of this study is to report the long-term clinical and radiological outcomes of patients treated with the TruFit™ plug for chondral defects within the knee. 11 patients underwent TruFit™ plug implantation. Long-term outcome scores were available for 6 patients at a mean follow up of 121 months (SD 12.0 months, 1 patient unavailable and 4 excluded after arthroplasty surgery). There was no statistically significant improvements in any score although all scores did improve. At a mean radiographic follow up of 70 months (17-113) of 9 patients, the mean MOCART score was 22.2 (SD 15.6). All patients had incomplete or no evidence of plug incorporation and persistent chondral loss. Based on these results, we do not recommend the use of the TruFit™ plug.

Role of Proton Pump Inhibitors in Laryngopharyngeal Reflux: Clinical Evaluation in a North Indian Population.

There has been an escalation of patients presenting with symptoms of Laryngopharyngeal reflux disease (LPRD) in the otorhinolaryngology clinics due to life style and dietary changes. This study was undertaken to evaluate the effect of various proton pump inhibitors in the treatment of LPRD using Reflux symptom index (RSI) and Reflux finding score (RFS). This was a prospective study conducted from June 2016 to February 2017 with a total of 240 patients with symptoms and signs of LPR. The patients were divided into 5 groups. Each group was subjected to particular proton pump inhibitor. There were 124 males 116 females with a mean age 34.3 and rural to urban ratio being 11. After 3 months, RFS and RSI score within each group, improved significantly with Proton pump inhibitor therapy. In our study patients who were treated with omeprazole 20 mg twice daily had the highest improvement in laryngeal symptoms and laryngeal findings. We conclude emphasizing the effectiveness of proton pump inhibitors with incorporation of lifestyle modification in the successful management of LPRD.

Blood pressure monitoring during arrhythmia: agreement between automated brachial cuff and intra-arterial measurements.

BACKGROUND: Since arrhythmia induces irregular pulse waves, it is widely considered to cause flawed oscillometric brachial cuff measurements of blood pressure (BP). However, strong data are lacking. We assessed whether the agreement of oscillometric measurements with intra-arterial measurements is worse during arrhythmia than during regular rhythm. METHODS: Among patients of three intensive care units (ICUs), a prospective comparison of three pairs of intra-arterial and oscillometric BP readings was performed among patients with arrhythmia and an arterial line already present. After each inclusion in the arrhythmia group, one patient with regular rhythm was included as a control. International Organization for Standardization (ISO) standard validation required a mean bias <5 (sd 8) mm Hg. RESULTS: In 135 patients with arrhythmia, the agreement between oscillometric and intra-arterial measurements of systolic, diastolic and mean BP was similar to that observed in 136 patients with regular rhythm: for mean BP, similar mean bias [-0.1 (sd 5.2) and 1.9 (sd 5.9) mm Hg]. In both groups, the ISO standard was satisfied for mean and diastolic BP, but not for systolic BP (sd >10 mm Hg) in our ICU population. The ability of oscillometry to detect hypotension (systolic BP <90 mm Hg or mean BP <65 mm Hg), response to therapy (>10% increase in mean BP after cardiovascular intervention) and hypertension (systolic BP >140 mm Hg) was good and similar during arrhythmia and regular rhythm (respective areas under the receiver operating characteristic curves ranging from 0.89 to 0.96, arrhythmia vs regular rhythm between-group comparisons all associated with P>0.3). CONCLUSIONS: Contrary to widespread belief, arrhythmia did not cause flawed automated brachial cuff measurements.

Improving communication with primary care to ensure patient safety post-hospital discharge.

INTRODUCTION: Successful communication between hospitals and primary care is of paramount importance to enable continuity of care and maintain patient safety post-discharge. Discharge summaries are the simplest way for GPs to obtain information about a patient's hospital stay. A quality improvement study was conducted with the aim of increasing the content of discharge summaries for inpatients in the authors' department. METHODS: A prospective review of 60 electronic discharge summaries was conducted over a 6-week period. The content of discharge summaries was reviewed in accordance with local trust guidelines. Targeted, intensive, cost and time-effective educational interventions were then conducted. A post-intervention review of 60 discharge summaries was performed. A further review of 60 discharge summaries was performed after 12 months. RESULTS: Initial results pre-intervention confirmed suboptimal content of discharge summaries. Post-intervention results showed each component of discharge summaries improved in terms of content, with six of eight components having a statistically significant (P<0.05) increase. This was maintained after 12 months. CONCLUSIONS: This study has demonstrated how simple, intensive educational sessions can lead to an improvement in discharge summaries and communication with primary care.

An isolated articular surface fracture of the distal patella: an unusual and previously unreported paediatric injury.

Paediatric patella fractures are uncommon, accounting for less than 1% of all paediatric fractures. This case report describes a previously undocumented patella fracture in a child, with a clear mechanism of injury. We present a case of a previously healthy 14-year-old boy who fell directly onto his right knee after coming off his pushbike. He sustained an isolated fracture involving the articular surface of the distal part of the patella with minimal displacement. The patient was managed conservatively in a Richard splint for three weeks, followed by a knee brace with gradually increasing degrees of flexion. He was instructed to be nonweight bearing for two weeks and then partial weight bearing for six weeks. At the final followup, after 9 weeks, the patient had full return of function and standard radiographs show the fracture to be healed. This case report has demonstrated how direct compression to the paediatric patella can cause a fracture isolated to its articular surface. It has detailed the natural progression of this injury to radiographic union, using a conservative management strategy. The authors believe that this case report provides an interesting insight into the variation of paediatric patella fractures and their contrasting management strategies.

Risk factors for native kidney dysfunction in patients with abdominal multivisceral/small bowel transplantation.

Kidney dysfunction is a recognized complication after non-renal solid organ transplantation, particularly after intestinal transplant. In our study, we reviewed data on 33 multivisceral transplant (MVT)- and 15 isolated small bowel (ISB)-transplant patients to determine risk factors for kidney dysfunction. Kidney function was estimated by modified diet in renal disease (MDRD) and Schwartz formula for adults and children, respectively. Acute kidney injury (AKI) was defined as an increase in the serum Cr (sCr) greater than twofold. Kidney function declined significantly at one yr after transplantation with 46% of subjects showing an estimated GFR (eGFR) <60 mL/min. Patients with an episode of AKI were more likely to have reduced eGFR than those without AKI (p < 0.025). In linear regression analyses, age, pre-transplant sCr, eGFR at postoperative day (POD) 30, 90, 180, 270, and tacrolimus level at POD 7 showed significant correlation with one yr post-transplant eGFR (p < 0.05). Pediatric patients and patients with MVT had lesser decline in kidney function compared with adults or patients with ISB. In conclusion, risk factors for post-transplant kidney dysfunction in intestinal transplantation included age, pre-transplant sCr, AKI episode, eGFR at POD 30, 90, 180, 270, and tacrolimus level at POD 7.

Reviewing radiographic images with patients: results of a trial on patient preferences, understanding, and satisfaction.

PURPOSE: To evaluate patient preferences, understanding, and satisfaction regarding visual review of radiographic images during counseling. PATIENTS AND METHODS: 101 urologic patients who presented for counseling where images impacted decision making were randomized into group A, shown their images, and group B, shown a diagram. Both completed a satisfaction survey blinded to the study's purpose. A second unblinded survey evaluated patient comprehension of and preferences regarding images. Comparison of intervention and control groups for differences in satisfaction and analysis of patient self-reported preferences and understanding regarding radiographic images was performed. RESULTS: Group A had higher satisfaction scores but did not reach statistical significance. Both groups reported comprehension of images (100%, 97.9%), improvement in understanding of their condition and treatment because of viewing images (98%, 95.8%), and felt images should be shown to all patients (92%, 89.6%). Multivariate analysis identified female sex to independently predict greater understanding of images and belief that all patients should be shown their images. CONCLUSIONS: Almost all patients reported comprehension of images, improvement in understanding because of review of images, and preference for being shown images. Female patients expressed greater understanding and preference for all patients to be shown their images. Review of radiographic images represents a potentially useful additional modality for patient counseling whose usefulness for improving satisfaction will need to be confirmed in further studies.

Risk-based fluconazole prophylaxis of Candida bloodstream infection in a medical intensive care unit.

Candida bloodstream infection (CBSI) accounted for 50% of bloodstream infections in our medical intensive care unit (MICU) in 2004. Our objective was to evaluate a risk-based fluconazole prophylaxis program. CBSI incidence, patient demographics, and unit metrics were retrospectively reviewed for 2004. Starting on January 2005, patients meeting pre-specified criteria were placed on risk-based fluconazole prophylaxis and their outcomes, adverse events, and unit metrics were prospectively collected. The inclusion criteria were based on a clinical prediction rule and included an MICU stay greater than 72 h, broad-spectrum antibiotics, and central venous catheter, along with at least two of the following: mechanical ventilation for at least 48 h, any type of dialysis, parenteral nutrition, pancreatitis, systemic steroids, or other systemic immunosuppressive agents. For 2004, the unit had nine CBSI, corresponding to a rate of 3.4 CBSI/1,000 line-days. Four cases were caused by C. albicans, four by C. glabrata, and one by C. tropicalis. The mean +/- standard deviation (SD) APACHE II score for these patients was 25 +/- 9. In 2005, a total of 36 patients (2.6% of all unit admissions) received prophylaxis and the unit had two CBSI, corresponding to a rate of 0.79 CBSI/1,000 line-days. One patient had C. albicans and the other had C. tropicalis. The mean +/- SD APACHE II score for these patients was 21 +/- 8. The mean +/- SD duration of fluconazole prophylaxis was 8 +/- 6 days. Fluconazole was discontinued in two patients due to non-severe adverse events (acute eosinophilia, elevated transaminases). The attributable cost of CBSI in the unit in 2004 was $63,000 per episode. The total cost for the 36 courses of fluconazole was $6,000. When comparing the 2004 CBSI patients and the 2005 prophylaxis patients, we found similar acuity, demographics, and risk factors, with no differences in MICU or hospital mortality or length of stay. Risk-based fluconazole prophylaxis in an MICU with a high incidence of CBSI was safe and cost-effective when applied to a limited number of patients and produced a significant decrease in the incidence of this disease.

[Pregnancy and delivery in a patient with Willebrand's disease. Apropos of a case]. / Maladie de von Willebrand et grossesse : à propos d'un cas.

Willebrand's disease is the most frequent inborn coagulopathy and type 3 is its most severe form. Pregnancy and delivery are critical events in women with Willebrand's disease of type 3. Prophylactic treatment for delivery and early postpartum period is recommended. We report the management of pregnancy and successful delivery of a 32-year-old woman with type 3. Prophylactic treatment with 2000 IU of Willebrand's disease factor (WdF) was given twice a day during the delivery day and the day after, and 1000 IU per day during the next three days. The patient did not show any spontaneous metrorrhagia but anemia. No bleeding was observed in the newborn.
