The Parkland Grading Scale for Cholecystitis (PGS) was developed as an intraoperative grading scale to stratify gallbladder (GB) disease severity during laparoscopic cholecystectomy (LC). We aimed to prospectively validate this scale as a measure of LC outcomes.
Methods
Eleven surgeons took pictures of and prospectively graded the initial view of 317?GBs using PGS while performing LC (LIVE) between 9/2016 and 3/2017. Three independent surgeon raters retrospectively graded these saved GB images (STORED). The Intraclass Correlation Coefficient (ICC) statistic assessed rater reliability. Fisher's Exact, Jonckheere-Terpstra, or ANOVA tested association between peri-operative data and gallbladder grade.
Results
ICC between LIVE and STORED PGS grades demonstrated excellent reliability (ICC?=?0.8210). Diagnosis of acute cholecystitis, difficulty of surgery, incidence of partial and open cholecystectomy rates, pre-op WBC, length of operation, and bile leak rates all significantly increased with increasing grade.
Conclusions
PGS is a highly reliable, simple, operative based scale that can accurately predict outcomes after LC.
Table of contents summary
The Parkland Grading Scale for Cholecystitis was found to be a reliable and accurate predictor of laparoscopic cholecystectomy outcomes. Diagnosis of acute cholecystitis, surgical difficulty, incidence of partial and open cholecystectomy rates, pre-op WBC, operation length, and bile leak rates all significantly increased with increasing grade. 相似文献
For many decades and until recently, medical approach to dermatologic diseases has been based on the physician's ability to recognize and treat symptoms. Nowadays, advances in the understanding of the biology of diseases and in technologies for intervening against them have allowed physicians to diagnose and treat underlying disease processes rather than simply addressing the symptoms. This means that rather than addressing ‘the disease in humans’, physicians can now address the particular pathologic (biologic, molecular) disturbance as it presents in the individual patient, i.e., physicians now can practice something much closer to ‘personalized medicine’, leading to greater benefits for the patients and the health of society in general. The deeper understanding of ultraviolet radiation, the importance of photoprotection and increased knowledge about signalling pathways of melanoma and carcinoma have led to more complete care for the dermatologic patient. The current popularity for excessive exposure to the sun, without adequate application of the appropriate photoprotection remedies, is the origin of melanoma, but also for the weakening of the structure and functions of the skin. Indeed, fragility of the skin can affect humans around the world. In the senior population, this skin fragility is accompanied by pruritus, whereas atopic dermatitis is an inflammatory disease with highest prevalence in children and adolescents. Acne, the number one reason for dermatologic consultations worldwide, increases its prevalence in adolescents and in females. Senescent alopecia affects humans after menopause and andropause. The articles in this publication present an overview of the current advanced understanding of the diagnosis and therapeutic approaches in 6 fields of dermatology – dermatopaediatry and gerontodermatology, oncodermatology, hair loss, atopic dermatitis, photoprotection and acne – and thereby serve as a useful compendium of updated information and references for all healthcare professionals who see patients with presentations of the symptoms of these diseases. 相似文献
Using data on waterfowl band recoveries, we identified spatially explicit hotspots of concentrated waterfowl movement to predict occurrence and spatial spread of a novel influenza A virus (clade 2.3.4.4) introduced from Asia by waterfowl from an initial outbreak in North America in November 2014. In response to the outbreak, the hotspots of waterfowl movement were used to help guide sampling for clade 2.3.4.4 viruses in waterfowl as an early warning for the US poultry industry during the outbreak . After surveillance sampling of waterfowl, we tested whether there was greater detection of clade 2.3.4.4 viruses inside hotspots. We found that hotspots defined using kernel density estimates of waterfowl band recoveries worked well in predicting areas with higher prevalence of the viruses in waterfowl. This approach exemplifies the value of ecological knowledge in predicting risk to agricultural security. 相似文献

Introduction: TRK fusions occur across a wide range of cancers in children and adults. These fusions drive constitutive expression and ligand-independent activation of the TRK kinase and are oncogenic. Larotrectinib is the first highly potent and selective small molecule ATP competitive inhibitor of all three TRK kinases to enter clinical development.
Areas covered: This review covers the current preclinical and clinical evidence for TRK inhibitors for TRK fusion cancers, focusing on larotrectinib.
Expert commentary: Larotrectinib has demonstrated a remarkable 75% centrally confirmed objective response rate in patients with TRK fusion cancers in phase 1 and phase 2 clinical trials with generally mild side effects. Responses appear independent of the patient’s age, underlying histology, and specific fusion partner and are durable in many patients. Larotrectinib is likely to be the first FDA-approved histology-agnostic molecularly targeted therapy. The evolving role of molecular profiling of advanced cancers is discussed. 相似文献
Severe skeletal open bite associated with posterior vertical maxillary excess and mandibular deformity is considered a difficult problem in orthodontic and surgical treatment. This study used a navigation system for the correction of severe skeletal open bite in order to accurately transfer the virtual plan to the actual operation and achieve precise rigid internal fixation in bimaxillary osteotomies of the jaws. Twelve patients with a severe skeletal open bite associated with vertical maxillary excess and mandibular deformity were recruited. All patients underwent Le Fort I osteotomy and bilateral sagittal split ramus osteotomy with the guidance of this navigation system. Computed tomography and cephalometric examinations were performed to evaluate the correction of the deformity. Deviations between the simulated plan and actual postoperative outcome were measured to determine the precision of the surgery. Satisfactory and stable results were achieved in all patients postoperatively, without complications or relapse during follow-up. Photographs and cephalometric evaluations showed that the facial profile and occlusion were improved. Assessment of the deviations between the simulated plan and actual postoperative outcome showed that the navigation system can precisely transfer the virtual plan to the actual operation. The results suggest that the navigation system can accurately transfer the virtual plan to the actual operation during bimaxillary jaw osteotomies, without relapse, in patients with a severe skeletal open bite. 相似文献
Patients with primary hyperparathyroidism are at risk for skeletal and renal end-organ damage.
Methods
We studied patients with biochemically confirmed primary hyperparathyroidism from 1995–2014 and quantified the frequency of osteoporosis, nephrolithiasis, hypercalciuria, and decrease in renal function.
Results
The cohort comprised 9,485 patients. In total, 3,303 (35%) had preexisting end-organ effects (osteoporosis, 24%; nephrolithiasis, 10%; hypercalciuria, 5%). Of 6,182 remaining patients, 1,769 (29%) exhibited progression to 1 or more end-organ effects over a median 3.7 years. Among patients with classic primary hyperparathyroidism (calcium and parathyroid hormone increased), progression was unrelated to the degree of hypercalcemia (calcium >11.5 mg/dL, hazard ratio 1.03, 95% confidence interval 0.85–1.25; 11.1–11.5 mg/dL, HR 1.07, 95% confidence interval 0.93–1.23; 10.5–11.0 mg/dL?=?reference). Patients with nonclassic primary hyperparathyroidism (calcium increased, parathyroid hormone 40–65 pg/mL) had a lesser risk of progression (calcium >11.5 mg/dL, hazard ratio 0.68, 95% confidence interval 0.50–0.94; 11.1–11.5 mg/dL, hazard ratio 0.68, 95% confidence interval 0.56–0.82; 10.5–11.0 mg/dL, hazard ratio 0.66, 95% confidence interval 0.59–0.74). End-organ damage developed before or within 5 years of diagnosis for 62% of patients.
Conclusion
End-organ manifestations of primary hyperparathyroidism develop before biochemical diagnosis or within 5 years in most patients. End-organ damage occurred more frequently in patients with classic primary hyperparathyroidism versus nonclassic primary hyperparathyroidism, regardless of severity of hypercalcemia. 相似文献
