    INTRODUCTION: As many as 3% of computed tomography (CT) scans detect pancreatic cysts. Because pancreatic cysts are incidental, ubiquitous and poorly understood, follow-up is often not performed. Pancreatic cysts may have a significant malignant potential and their identification represents a 'window of opportunity' for the early detection of pancreatic cancer. The purpose of this study was to implement an automated Natural Language Processing (NLP)-based pancreatic cyst identification system. METHOD: A multidisciplinary team was assembled. NLP-based identification algorithms were developed based on key words commonly used by physicians to describe pancreatic cysts and programmed for automated search of electronic medical records. A pilot study was conducted prospectively in a single institution. RESULTS: From March to September 2013, 566,233 reports belonging to 50,669 patients were analysed. The mean number of patients reported with a pancreatic cyst was 88/month (range 78-98). The mean sensitivity and specificity were 99.9% and 98.8%, respectively. CONCLUSION: NLP is an effective tool to automatically identify patients with pancreatic cysts based on electronic medical records (EMR). This highly accurate system can help capture patients 'at-risk' of pancreatic cancer in a registry.

    Non-randomised prospective clinical trial to improve follow-up adherence, survivorship knowledge and late effects documentation at a childhood cancer clinic in Western Kenya: a study protocol
    (BMJ, 2025-06-10) Lemmen, Jesse; Mageto, Susan; Vik, Terry; Olbara, Gilbert; Kaspers, Gertjan; Njuguna, Festus; Pediatrics, School of Medicine
    Introduction: International survivorship guideline consortia have developed strategies to prevent, detect and manage late effects of childhood cancer survivors. However, recommendations do not adequately reflect the everyday reality of paediatric oncology care in low- and middle-income countries. In this study protocol, a survivorship intervention programme, comprising an educational component and a follow-up component, is described. The Educational Programme aims to improve follow-up adherence of childhood cancer survivors through increasing survivorship knowledge of caregivers. The Follow-up Programme aims to map late effects by implementing a follow-up form at the outpatient clinic to be used by trained healthcare providers. Methods and analysis: This non-randomised prospective clinical trial will be performed at a referral hospital in Western Kenya. 100 caregivers of children diagnosed with cancer, who will complete treatment within 2 months, will be enrolled and followed for 24 months after completion of treatment. A caregiver control group receiving usual care will be recruited, and sequentially, caregivers will be included in an intervention group to attend an educational group session where they receive educational materials (video, booklet and Survivorship Card). Primary study outcome will be survivors' follow-up adherence. Survivors will be considered lost to follow-up after they miss a scheduled appointment and do not revisit the clinic for more than 6 months. Mixed models regression analyses will be performed to determine intervention effects on follow-up adherence and on caregiver survivorship knowledge uptake. Additionally, healthcare providers will be trained on follow-up care, whereafter a form will be introduced at the outpatient clinic to document late effects in paediatric survivors attending the clinic for the period of a year. Secondary outcomes will be late effects prevalence as documented in the follow-up form and caregiver and healthcare provider survivorship knowledge uptake. Implementation measures (reach, potential effectiveness, adoption, satisfaction and maintenance) will be evaluated for both programmes. Ethics and dissemination: The Institutional Research and Ethics Committee has approved the study protocol. Findings will also be shared with governmental and non-governmental organisations that support children with cancer in Kenya to inform their target audiences and guide their policy development.Lessons learnt from this study could inform healthcare providers and policy makers on how to shape survivorship programmes in the Kenyan context and possibly implement similar programmes in other centres in Sub-Saharan Africa.

    Surgical approach to limiting skin contracture following protractor myectomy for essential blepharospasm
    (Massachusetts Eye and Ear Infirmary, 2017-11-05) Clark, Jeremy; Randolph, John; Sokol, Jason A.; Moore, Nicholas A.; Lee, Hui Bae H.; Nunery, William R.; Ophthalmology, School of Medicine
    Purpose: To report our experience with protractor myectomy in patients with benign essential blepharospasm who did not respond to serial botulinum toxin injection, and to describe intra- and postoperative techniques that limited skin contracture while also providing excellent functional and cosmetic results. Methods: The medical records of patients with isolated, benign, essential blepharospasm who underwent protractor myectomy from 2005 to 2008 by a single surgeon were reviewed retrospectively. The technique entailed operating on a single eyelid during each procedure, using a complete en bloc resection of all orbicularis tissue, leaving all eyelid skin intact at the time of surgery, and placing the lid under stretch with Frost suture and applying a pressure dressing for 5-7 days. Results: Data from 28 eyelids in 7 patients were included. Average follow-up was 21.5 months (range, 4-76 months). Of the 28 eyelids, 20 (71.4%) showed postoperative resolution of spasm, with no further need for botulinum toxin injections. In the 8 eyelids requiring further injections, the average time to injection after surgery was 194 days (range, 78-323 days), and the average number of injections was 12 (range, 2-23 injections). All but one eyelid had excellent cosmetic results, without signs of contracture; one eyelid developed postoperative skin contracture following premature removal of the Frost suture and pressure dressing because of concerns over increased intraocular pressure. Conclusions: In our patient cohort, this modified technique resulted in excellent cosmetic and functional results and limited postoperative skin contracture.
