A wide spectrum of nowadays availible radiological and imaging methods in the diagnostic evaluation of patients with colorectal cancer enabled not only the improvement of primary colorectal malignancy detection, precise staging, regional involvement and metastatic spread assessment, but also the posttherapeutical estimation and follow- up. Having in mind that the exact diagnostic assessment of colorectal carcinoma by use of different imaging modalities still raises a lots of contradictories, in this report we have tried to present the possibilities of newer imaging techniques in the diagnostic evaluation of the patients with colorectal cancer.

Cystic echinococcosis (CE) or hydatidosis (hydatid cysts) is an infection with a wide spectrum of manifestations, from symptomatic infection to fatal disease. Ultrasound (US) allows screening, diagnosis, differential diagnosis, treatment guidance and follow-up of CE under many circumstances. Hydatid cysts are predominantly observed in the liver. Herewith we present a review to demonstrate established and innovative imaging features of CE of the hepatobiliary tract.

Phakomatoses are a group of more than 30 entities with an inheritance pattern that primarily affects the central nervous system, skin, viscera and connective tissue. The aim of this paper is to make an educational review of the most common radiological findings on phakomatoses through the iconography of the cases collected in our magnetic resonance imaging (MRI) and computer tomography (CT) units over the last ten years. Also, we describe and illustrate by these techniques the main features of the most common entities within the wide spectrum of diseases. As highly variable and age dependent, imaging techniques have an important role in the diagnosis and follow-up of these patients. Increased awareness for the need to implement and conduct screening programs could be considered as a solution to prevent late diagnosis and to treat the patients in early stages of disease.

Colorectal cancer (CRC) is the third leading cause of cancer-related deaths worldwide. It has been estimated that more than one-third of patients are diagnosed when CRC has already spread to the lymph nodes. One out of five patients is diagnosed with metastatic CRC. The stage of diagnosis influences treatment outcome and survival. Notwithstanding the recent advances in multidisciplinary management and treatment of CRC, patients are still reluctant to undergo screening tests because of the associated invasiveness and discomfort (e.g., colonoscopy with biopsies). Moreover, the serological markers currently used for diagnosis are not reliable and, even if they were useful to detect disease recurrence after treatment, they are not always detected in patients with CRC (e.g., CEA). Recently, translational research in CRC has produced a wide spectrum of potential biomarkers that could be useful for diagnosis, treatment, and follow-up of these patients. The aim of this review is to provide an overview of the newer noninvasive or minimally invasive biomarkers of CRC. Here, we discuss imaging and biomolecular diagnostics ranging from their potential usefulness to obtain early and less-invasive diagnosis to their potential implementation in the development of a bespoke treatment of CRC.

AbstractThe aim of this review was to identify the imaging methods at our disposal to optimally manage posterior uveitis at the present time. The focus was put on methods that have become available since the 1990s, some 30 years after fluorescein angiography had revolutionised imaging of posterior uveitis in particular imaging of the retinal vascular structures in the 1960s. We have focussed our review on precise imaging methods that have been standardised and validated and can be used universally thanks to commercially produced and available instruments for the diagnosis and follow-up of posterior uveitis. The second part of this imaging review will deal with invasive imaging methods and in particular ocular angiography.

Abstract Background The precise content and frequency of follow-up of patients with colorectal cancer (CRC) is variable and guideline adherence is low. The aim of this study was to assess the view of colorectal surgeons on their local follow-up schedule and to clarify their opinions about risk-stratification and organ preserving therapies. Equally important, adherence to the Dutch national guidelines was determined. Methods Colorectal surgeons were invited to complete a web-based survey about the importance and interval of clinical follow-up, CEA monitoring and the use of imaging modalities. Furthermore, the opinions regarding physical examination, risk-stratification, organ preserving strategies, and follow-up setting were assessed. Data were analyzed using quantitative and qualitative analysis methods. Results A total of 106 colorectal surgeons from 52 general and 5 university hospitals filled in the survey, yielding a hospital response rate of 74% and a surgeon response rate of 42%. The follow-up of patients with CRC was mainly done by surgeons (71%). The majority of the respondents (68%) did not routinely perform physical examination during follow-up of rectal patients. Abdominal ultrasound was the predominant modality used for detection of liver metastases (77%). Chest X-ray was the main modality for detecting lung metastases (69%). During the first year of follow-up, adherence to the minimal guideline recommendations was high (99–100%). The results demonstrate that, within the framework of the guidelines, some respondents applied a more intensive follow-up and others a less intensive schedule. The majority of the respondents (77%) applied one single follow-up imaging schedule for all patients that underwent treatment with curative intent. Conclusions Dutch colorectal surgeons’ adherence to minimal guideline recommendations was high, but within the guideline framework, opinions differed about the required intensity and content of clinical visits, the interval of CEA monitoring, and the importance and frequency of imaging techniques. This national survey demonstrates current follow-up practice throughout the Netherlands and highlights the follow-up differences of curatively treated patients with CRC.

Background: Colorectal cancer has been defined and discussed as a disease of middle or late life. However, no age-group is exempt, and adenocarcinoma of the colon has been reported in young age. Malignant disease is frequently found in young adults in our Kashmir valley. Objective (s): This aim was to study the clinic pathological features, diagnosis, management and outcome of colorectal cancer in young adults under the age of 40. Material and Methods: This combined Retrospective (January 2002 to May, 2004) Prospective (June 2004 to September 2006) Observational Study was conducted in the department of General and Minimal Access Surgery, SKIMS,. Total of 62 young colorectal carcinoma patients were studied. The case records of all the patients of colorectal cancer less than 40years of age admitted in the department of General Surgery were reviewed retrospectively. In the prospective study all the patients less than 40 years of age with colorectal carcinoma admitted in our department were registered. Following the confirmation of diagnosis, the patients were subjected to exploratory laparotomy. The nature of the surgical procedure depended upon the intra-operative findings. All the patients were subjected to postoperative chemotherapy and in selected cases to postoperative chemo-radiation. The patients were followed for a period of five years .The patients were thoroughly examined and investigated on follow up to rule out any recurrence or metastasis. Results: Most of our patients (83.9%) were admitted through outpatient department (OPD) and only 10 patients (16.1%) were admitted through emergency. In our study, the male: female ratio was 1.58: 1.The mean age in our study was 30.2 years. Bleeding per rectum was the most common (74.2%) presenting symptom followed by altered bowel habits (72.6%). Carcinoembryonic antigen (CEA) levels show significant decline after surgery/adjuvant therapy. Colonoscopy detected synchronous growths in 5.3% of patients. Rectum was the most common site of lesion (32.2%) while combined rectum and sigmoid colon (including recto sigmoid) accounted for 62.7% of lesions. Resection with intention of cure was performed in 68.3% of patients, palliative procedure in 26.7% and biopsy in 5% of patients. Postoperative complications were recorded and managed accordingly. Typical adenocarcinoma was seen in 80.6% of patients. None of our patients had Dukes stage A presentation. 13.6% of patients had local recurrence and 25.4% had metastasis on follow up.                                                 Conclusion: Colorectal cancers in young adults are quite common in Kashmir valley. Outcome of CRC in young patients is significantly related to the procedure - whether done with curative intention or for palliation. Henceforth, surgical treatment should be radical and optimized with adjuvant therapy where possible to achieve the best prognosis. The diagnosis of colorectal cancer should be done at the early and curable stage for better outcome.

Distal Forearm Fractures

Abstract Background Following surgery, the standard regimen for fractures of the distal forearm includes radiographs taken 2-weeks postoperatively. However, it is unclear whether these radiographs have any therapeutic risks or benefits for patients. Objective The purpose of this study is to determine the importance of radiographs taken 2-weeks after surgery on distal forearm fractures, especially if it leads to further operations, and to establish whether this practice should be continued. Materials and Methods This is a retrospective cohort study of patients with a distal forearm fracture treated surgically with a volar locking plate at two university hospitals in Denmark. Standard aftercare at both departments is 2 weeks in a cast. Patients attend a 2-week follow-up, at which the cast is replaced with a removable orthosis and radiographs are taken. It was recorded whether these radiographs had resulted in any change of treatment in terms of further operations, prolonged immobilization, additional clinical follow-up, or additional diagnostic imaging. Results A total of 613 patients were included in the study. The radiographs led to a change of standard treatment for 3.1% of the patients. A second operation was required by 1.0%; 0.5% were treated with prolonged immobilization, and 1.6% had additional outpatient follow-up due to the findings on the radiographs. Additional diagnostic imaging was performed on 1.9% of the patients. Conclusion The radiographs taken at the 2-weeks follow-up resulted in a change of treatment in 3.1% of the cases. Given the low cost and minimal risk of radiographs of an extremity, we concluded that the benefits outweigh the costs of routine radiographs taken 2 weeks after surgical treatment of distal forearm fractures.
