Multiparametric MRI prostate PI-RAD scoring in a district general hospital: correlating PI-RADS 3 results with histological findings.

OBJECTIVE: Prostate cancer is the most common male cancer in the UK. In many hospitals, patients are now being referred for a multiparametric (mp) MRI scan of their prostate as part of an evaluation for the presence of prostate cancer, prior to an ultrasound-guided biopsy. Prostate Imaging Reporting and Data System (PI-RADS) score of 3 are defined as "equivocal" for the presence of prostate cancer. Thus, a PI-RADS 3 lesion does not confidently determine whether there is significant prostate disease or not.Our aim is to determine the correlation of PI-RADS 3 prostatic lesions with histology proven, clinically significant cancer. METHODS: We performed a retrospective review on a cohort of 143 consecutive patients. Each patient underwent a mp-MRI scan of their prostate given a PI-RADS score. PI-RADS 3 lesions were analysed further based on histology and categorised into malignant and non-malignant lesions. Prostate-specific antigen (PSA) results and prostatic volume of PI-RADS 3 lesions were also analysed. RESULTS: We identified 45 patients with PI-RADS 3 lesions out of 143 patients. 32 patients subsequently underwent transrectal/transperineal ultrasound-guided biopsy. 43% of patients were found to have had a malignant prostatic adenocarcinoma on histology. The remaining 56% had non-malignant findings. Of those with malignant disease, there was a higher median PSA and lower mean prostatic volume. CONCLUSION: The study confirms that a score of PI-RADS 3 does not accurately differentiate between malignant and non-malignant lesions. Further investigations such as ultrasound-guided prostate biopsy and PSA parameters are required to accurately ascertain the nature of a prostate lesion with PI-RADS score 3. ADVANCES IN KNOWLEDGE: An ultrasound-guided prostate biopsy in patients with PI-RADS 3 remains of paramount importance when distinguishing malignant vs non-malignant lesions. Multicentre data of MRI findings with PI-RADS 3 scores is required to yield a sample size large enough to carry out statistical analysis.

How to Create a Great Radiology Report.

The radiology report represents the sum of a radiologist's highest level of synthesis and insight into a patient's condition. It is the most important product that radiologists generate to help direct patient care. Despite the self-evident importance of clear and effective radiology reporting, radiologists usually receive little or no formal reporting education during training. Instead, it is learned in a piecemeal and often indirect fashion through occasional correction and imitating the reports of other radiologists. The audience of the radiology report extends far beyond the ordering provider and includes patients and their families, medical support staff, subspecialty providers, other radiologists, and research interests. Creating a report that fulfills the needs of this diverse group is a formidable if not quixotic ambition. However, there are certain key principles to reporting the imaging findings, impression, and recommendations that serve as a guide and promote careful consideration about how reports are understood. The findings section should emphasize short, informative, and factual observations while avoiding inappropriate interpretation, excessive use of terms of perception, and redundancy. The impression is the thoughtful synthesis of the meaning of the findings leading to a diagnosis, a differential diagnosis, and management recommendations. Creating a clear and impactful impression allows radiologists to provide the highest level of clinical care and direction but takes time and effort beyond simply restating the findings. The impression should use language that is understandable, memorable, and actionable. Reporting skills require ongoing attention and must adapt to the evolving practice patterns and communication styles in medicine. ©RSNA, 2020.

Dysphagia aortica: a rare cause of dysphagia.

Dysphagia is uncommon; however, it is considered a warning symptom, especially in the elderly population, and should prompt consideration of a neoplasm of the oesophagus. Dysphagia aortica is rare and often not considered in clinical practice. It is caused by any abnormality of the aorta that results in dysphagia. These include thoracic aortic aneurysm, aortic dissection and even a tortuous aorta. Our case is of an elderly woman, in her early 70s, with a history of treated colorectal carcinoma and hypertension, who presented with progressive dysphagia to solid foods, which, on investigations, showed a tortuous aorta causing compressions of the oesophagus at multiple levels. She was managed with dietary adjustment and optimal control of blood pressure.

Increasing Incidence of Colorectal Cancer, Starting at a Younger Age for Rectal Compared to Colon Cancer in Brunei Darussalam.

BACKGROUND: Colorectal cancer (CRC) is the most common gastrointestinal malignancy and is a significant cause of mortality. Its incidence is generally increasing in Asia. Reports from the West have indicated that the incidence of rectal cancer is increasing in the younger population. This study assessed the time trend of CRC in Brunei Darussalam specifically assessing the different age groups at which the incidences start to increase. MATERIALS AND METHODS: The National Cancer registry was reviewed (1991 to 2014). The age standardized rate (ASR) and the age specific incidence rates (ASIRs) for three time periods (1991-1998), (1999-2006) and (2007-2014) were calculated. RESULTS: The mean age of diagnosis was 59.3±14.6 years old, incidences being slightly higher amongst men (57.6%) and Malays (67.1%). The most common tumor type was adenocarcinoma (96.4%). Rectal cancers accounted for 35.2% (n=372/1,056) of all cancers of the large bowel; more men were affected than women. The proportion of rectal cancer was also high among the indigenous group. In the three time periods, the ASR for CRC increased from 16 per 100,000 (1991-1998) to 19.6 per 100,000 (1999-2006) and 24.3 per 100,000 (2007-2014). The ASIRs for CRC increased markedly between the time periods 1998-2006 and 2007-2014, beginning in the 40-44 years age group. For rectal cancers, the ASIRs started to increase in the 25-29 age group onward whereas for colon cancers, the increase was observed at a later age, starting from the 45-49 age group. CONCLUSIONS: Our study showed an increase in the incidence of CRC including in the younger age groups. The increase was seen earlier in rectal cancer compared to colon cancer. These data mirror the trends reported from the West.

Characteristics of young colorectal cancer in Brunei Darussalam: an epidemiologic study of 29 years (1986-2014).

BACKGROUND: Colorectal cancer (CRC) is the most common gastrointestinal cancer and the incidence is increasing. CRC is more common with increasing age, but a proportion occurs in young adults, termed young CRC. This study assessed the incidence and the demographic of young CRC in Brunei Darussalam. MATERIALS AND METHODS: All histologically proven CRC between 1986 and 2014 registered with the Department of Pathology cancer registry were reviewed and data extracted for analyses. Young CRC was defined as cancer in patients aged less than 45 years. The various population groups were categorized into locals (Malays, Chinese and Indigenous) and expatriates. RESULTS: Over the study period, there were 1,126 histologically proven CRC (mean age 59.1 ± 14.7 years, Male 58.0%, Locals 91.8% and 8.2% expatriates). Young CRC accounted for 15.1% with the proportion declining over the years, from 29% (1986-1990) to 13.2% (2011-2014). The proportion of young CRC was highest among the indigenous (30.8%), followed by the expatriates (29.3%), Malays (14.3%) and lowest among the Chinese (10.8%). The mean age of young CRC was 35.9 ± 6.2; lowest among the indigenous (33.5 ± 6.7), expatriate (34.9 ± 6.0) groupd and the Malays (35.6 ± 6.5) compared to the Chinese (38.6 ± 4.6), a similar trend being observed in the non-young CRC groups. There were no difference between the genders and tumor locations (rectum or colon) between the young and the non-young CRC cases. Female young CRC was significantly younger than male (p<0.05) without any significant variation between the various population groups (p>0.05). CONCLUSIONS: Our study showed that the young CRC accounted for 15.1% of all CRC with declining trend observed over recent years. Young CRC was more common among indigenous, expatriates and Malays and least common among the Chinese. There were no differences in the gender and tumor locations.

Sigmoid volvulus in pregnancy: early diagnosis and intervention are important.

Bowel obstruction is rare in pregnancy, and delay in recognition can lead to serious maternal and fetal complications. Most reported causes of bowel obstruction in pregnancy (adhesions, intussusception, hernia, and carcinoma) require surgical intervention. Sigmoid volvulus is an acute surgical cause that can now be managed successfully without surgery. We report the case of 33-year-old lady who presented with a sigmoid volvulus that was successfully managed with urgent endoscopic decompression.

Signet Ring Cell Lymphoma of the Small Bowel: A case report.

Gastrointestinal lymphoma of the bowel is uncommon compared to adenocarcinoma. Signet ring cell lymphoma (SRCL) is a rare variant of non-Hodgkin's lymphoma that is characterized by clear cytoplasm with displaced nuclei to the periphery giving a signet ring appearance. Small bowel involvement has not been previously reported. We report the rare case of a 78-year-old female who presented with short history of fever, loss of appetite, nausea, vomiting, mild weight loss with abdominal discomfort and was later diagnosed to have SRCL of the ileum.

Gas patterns on plain abdominal radiographs: a pictorial review.

Abdominal radiographs are one of the most commonly performed radiological examinations and have an established role in the assessment of the acute abdomen. The main indication is for suspected bowel obstruction and in conjunction with an erect chest x-ray for suspected visceral perforation. Often, the pattern of gas points to a particular pathology, and accurate interpretation is important for prompt diagnosis. The diagnosis in most cases will be confirmed by further imaging studies such as ultrasound, contrast studies or, most commonly in contemporary practice, CT. This pictorial review summarises the various types of intraluminal and extraluminal gas patterns, illustrates some of the common clinical diagnoses made from plain films, describes some commonly encountered clinical problems with radiographs, and discusses the role of advanced imaging techniques.

Imaging in childhood scoliosis: a pictorial review.

Childhood scoliosis is a common clinical entity with a number of different causes. In the majority of cases, the scoliosis is idiopathic, but it may be the manifestation of an occult spinal pathology. The clinical history and examination may elicit certain worrying features such as pain, neurological symptoms or an atypical curve pattern. These findings should prompt advanced imaging, as early and accurate detection of an underlying cause allows optimal planning and timing of surgery and helps reduce associated risks. The most common occult pathologies detected by advanced imaging are Arnold Chiari malformations, syringohydromyelia and closed spinal dysraphism such as diastematomyelia. Advanced imaging techniques, in particular multiplanar MRI, are also increasingly requested in children with known congenital scoliosis associated with spinal dysraphism and developmental causes of scoliosis such as neurofibromatosis and Klippel-Feil syndrome, as it allows superior delineation of the spinal column without the radiation risk. This review aims to examine the different imaging techniques currently used in the evaluation of scoliosis and provide a pictorial summary of the more common causes and associations.

Is there a place for e-learning in clinical skills? A survey of undergraduate medical students' experiences and attitudes.

BACKGROUND: e-learning is established in many medical schools. However the effectiveness of e-learning has been difficult to quantify and there have been concerns that such educational activities may be driven more by novelty, than pedagogical evidence. Where some domains may lend themselves well to e-learning, clinical skills has been considered a challenging area for online learning. AIMS: The aims of this study are to assess undergraduate medical students? perceived level of IT ability and accessibility, and attitudes towards e-learning in basic clinical skills education, compared to other teaching methods. METHODS: A self-administered questionnaire was developed to capture undergraduate medical students: (i) demographic details (ii) perceived level of IT ability and accessibility (iii) experiences and attitudes towards e-learning and clinical skills training. Responses were linked to student?s performance in a clinical skills OSCE. RESULTS: The majority of students reported good access to computers and the internet, both on and off campus and appear confident using IT. Overall students felt that e-learning had a positive impact on their learning of clinical skills and was comparable to other traditional forms of clinical skills teaching. Students who displayed deep learning traits when using e-learning, performed better in clinical skills OSCEs. CONCLUSION: Undergraduate medical students value the use of e-learning in clinical skills education, however they vary in their utilization of such learning environments. Students rate e-learning just as highly as other traditional methods of clinical skills teaching and acknowledge its integration in a blended approach. Developers of clinical skills curricula need to ensure e-learning environments utilize media that encourage deeper approaches to learning.
