Radiology in Rwanda

This account documents some aspects of military radiology in the aftermath of the Rwandan Civil War of 1994. Following the genocidal conflict of April-July 1994, all radiographic services ceased in Rwanda, a nation of some 7 500 000 people. As part of the United Nations Peacekeeping Force, UNAMIR II, the Australian Medical Support Force established and provided, on an ongoing basis, sophisticated medical, surgical and intensivist care for the sick and wounded United Nations personnel, of whom there were up to 7000 deployed in Rwanda; and, as part of its humanitarian outreach, emergency medical and surgical care for Rwandese civilians. The Australian contingent of 308 service personnel established the Australian Military Hospital (the ‘United Nations Hospital’) in the former Clinic Wing of the Kigali Central Hospital. From August 1994 the Radiology Department of the Australian Medical Support Force provided the first specialist X-ray services as part of the re-building of the stricken nation and, over the ensuing year, provided a diagnostic service for soldiers and civilians with both chronic and recent war wounds, trauma victims in the aftermath of the Civil War, sick and injured soldiers and Rwandese suffering from any of the full range of medical conditions encountered in tropical Africa.     

Complications of epilepsy and a ruptured pyonephrosis: Radiology to the rescue in the Brooks murder case

A woman and her lover were accused of murdering the woman's husband. Five weeks after fracture/dislocations of both shoulders and a central fracture/dislocation of the right hip were diagnosed the woman's husband died of septicaemia consequent on a ruptured infected hydronephrosis. The shoulder and hip injuries and the ruptured hydronephrosis were attributed to a beating with a blunt instrument. A review of the medical records of the deceased, particularly his radiological examinations, led the authors to conclude that his joint injuries and ruptured kidney were not due to the alleged assault. The joint injuries were the consequence of epileptic seizures and the ruptured kidney was also due to natural causes. These medical opinions provided evidence that led to acquittal of the accused.     

The value of comprehensive genomic sequencing to maximize the identification of clinically actionable alterations in advanced cancer patients: a case series

Purpose: We present seven cases of advanced cancer patients who initially underwent tumor testing utilizing smaller, panel-based tests, followed by a variety of therapeutic treatments which ultimately resulted in progression of their disease. These cases demonstrate the value of utilizing WES/RNA seq and characterization following disease progression in these patients and the determination of clinically targetable alterations as well as acquired resistance mutations.Materials and Methods: All patients are part of an IRB approved observational study. WES and RNA sequencing were performed, using GEM ExTra^® on tumor and blood samples obtained during routine clinical care. To accurately determine somatic versus germline alterations the test was performed with paired normal testing from peripheral blood.Results: The presented cases demonstrate the clinical impact of actionable findings uncovered using GEM ExTra^® in patients with advanced disease who failed many rounds of treatment. Unique alterations were identified resulting in newly identified potential targeted therapies, mechanisms of resistance, and variation in the genomic characterization of the primary versus the metastatic tumor.Conclusions: Taken together our results demonstrate that GEM ExTra^® maximizes detection of actionable mutations, thus allowing for appropriate treatment selection for patients harboring both common and rare genomic alterations.     

Molecular predictive testing in precision oncology: The Italian experience

In this review, we describe molecular pathology testing to predict response to targeted treatment of solid tumors, focusing on Italian routine clinical practice. The combination of the universal health care system organized at national, regional, and local levels has led a decentralized model, with a large number of local laboratories performing in-house molecular testing following guidelines issued and external quality assessment organized by the Italian Society of Pathology and Cytopathology–Italian Division of the International Academy of Pathology. In this framework, in the early days of predictive testing, sponsored informatics platforms support to set up national programs that aimed to integrate the activity of oncologists and pathologists to test cancer patients for druggable alterations. More recently, reimbursement for molecular testing is being covered completely by the Italian National Health Service. In the near future, considering the development of complex technologies, we expect that outsourcing samples to next-generation sequencing referral laboratories will take place.     

The role of hematopoietic cell transplantation in adult ALL: Clinical equipoise persists

Adults with acute lymphoblastic leukemia (ALL) in first complete remission (CR1) may be treated either with ongoing systemic chemotherapy or with allogeneic hematopoietic cell transplantation (alloHCT). Despite the presence of phase III trials to support clinical decision-making, we hypothesized that physicians who treat adult ALL would demonstrate wide practice variation. Canadian hematologists who treat ALL were surveyed electronically. Overall, 69 of 173 physicians responded (40%). There was high agreement with offering alloHCT for ALL with high-risk cytogenetics or induction failure after a single chemotherapy cycle. However, only a minority of respondents felt that age >35 years was an indication for alloHCT in CR1. Almost all respondents (96%) felt that a well-matched unrelated donor was an acceptable alternative to a sibling donor. There was uncertainty about the role of cord blood (53% agree) and the utility of reduced intensity conditioning HCT (41% agree). In contrast to the results of the MRC/ECOG study, respondents considered alloHCT to be particularly helpful in high-risk patients. Consensus was lacking on the use of cord blood, RIC alloHCT, and the application of MRD. Equipoise exists on the role of alloHCT in CR1 in ALL, suggesting that further trials in this area are required.     

The cognitive-spiritual dimension - an important addition to the assessment of quality of life: Validation of a questionnaire (SELT-M) in patients with advanced cancer

Questions of meaning and challenge by illness, i.e., the spiritual dimension of quality of life (QL) traditionally played an important role in anthroposophically oriented medicine and have gained importance in palliative medicine and supportive care. In the context of a research project on QL in patients with advanced cancer, we therefore investigated the psychometric properties of a questionnaire covering spiritual QL issues, with the aim of providing a module for the assessment of cognitive-spiritual QL.Patients and methods: We investigated 89 patients with advanced breast and gastro-intestinal cancer. Construct validity of a modified version of the SELT (Skalen zur Erfassung von Lebensqualität bei Tumorkranken), the SELT-M was tested by multitrait scaling analysis. Discriminant and convergent validity were also tested. The EORTC QLQ-C30 was used as a standard for validation.Results showed the SELT-M as feasible in administration. Four of the five SELT-M subscales were internally consistent (Cronbach's Alpha = >0.7). The subscale on spiritual QL showed higher within than outside subscale correlations for six of its eight items. Association of the SELT-M with the EORTC QLQ-C30 was good for the items and subscales covering the same aspects of QL in both questionnaires: emotional (Spearman r = 0.61), physical functioning (r = –0.54) and fatigue (r = –0.75). In accordance with expectations, there was no association between spiritual QL with any EORTC QLQ-C30 subscales. Self-assessed spiritual QL in the SELT-M corresponded well with interviewer assessments (test for trend accross ordered groups, P = 0.0023).Conclusions: Overall there is confirming evidence for the hypothesised structure of the SELT-M, especially for the newly developed module on spiritual QL. This module may be used as a module together with other cancer specific QL questionnaires.     

Lung cancer and molecular testing in small biopsies versus cytology: The Logics of Worlds

The 8th Annual National Molecular Cytopathology Meeting, held in Naples, Italy, on December 2 to 3, 2019, addressed updates in diagnostic cytopathology and molecular classifications and specifically focused on lung cancer biomarker testing in cytology samples. Lung cancer continues to be the most commonly diagnosed noncutaneous malignancy in the world. In the majority of patients, lung cancers are frequently identified when they cannot be surgically accessed, and this leads to the use of cytology for a diagnosis and theragnostic testing. The meeting was an international forum for discussing new roles and updates for cytopathology in molecular testing as the basis for provoking new trends and novel approaches. The relevant literature is referenced. The significance of these updates for the practice of pathology in general is discussed.     

The Hutson loop and prosthesis: Clinical uses in hepato-biliary intervention

A number of method of making a Roux-en-Y hepaticojejunostomy have been advocated to help the radiologist gain access to the biliary system. We have found markers and rings unsatisfactory and therefore designed and tested our own prosthesis. Reliable rapid access is easily achieved using this device with a much reduced radiation dose to both patient and radiologist. The prosthesis has been used for the past 3 years, and the last 23 patients are reviewed. Seven patients have required repeated interventions via the loop and we present the findings and our results.
