RESUMO
INTRODUCTION: Claustrophobia is a major problem experienced by some patients referred for magnetic resonance imaging (MRI). This results in significant costs and delays to healthcare service provision due to appointment cancellations or patients' inability to complete MRI examinations. Radiographers may use several strategies to effectively manage patients with claustrophobia during MRI. This study aimed to determine radiographer's confidence in managing patients with claustrophobia and evaluate the perceived effectiveness of the intervention approaches employed. METHODS: With institutional ethical approval, an online survey was conducted (15th September to 9th November 2020) among Kuwaiti MRI radiographers. The survey was designed to obtain information relating to participant demographics and the perceived confidence of radiographers in their use of interventions to manage claustrophobia during MRI procedures. Data obtained were analysed using the Statistical Package for the Social Sciences (v.26). RESULTS: A total of 144 valid responses were obtained. Of the respondents, 82% (n = 118) were confident that they could support claustrophobic patients during MRI examinations. Almost all respondents (97.9%, n = 141) employed various claustrophobia reduction and relaxation techniques to improve patient experience and increase scan completion rates. There was a significant association between radiographer's level of education (rs = +0.18, p = 0.028) and experience (rs = +0.33, p < 0.001) with their confidence managing claustrophobic patients. While participating radiographers considered lectures and training the most effective methods to improve their skills in managing such patients, educating claustrophobic patients prior to their MRI scan was the most effective technique for facilitating scan completion. CONCLUSION: Kuwaiti MRI radiographers are confident in applying different claustrophobic management techniques to improve patient compliance. Patient education, through supportive discussion, prior to their MRI examination was identified as the most effective intervention for managing claustrophobia. IMPLICATIONS FOR PRACTICE: Patient education before MRI examination is necessary to enhance their experience and optimise scan completion rates. In addition, it is essential that MR radiographers develop their practical competence in supporting patients with claustrophobia during their scans.

Star-fruit ingestion has been previously reported to cause severe neurotoxicity in uremic patients with symptoms ranging from hiccups, vomiting and consciousness disturbances to refractory status epilepticus, coma and death. MRI examinations of five uremic patients with severe neurological disturbances following star-fruit intoxication were reviewed. At the time of MRI, all patients presented with a confusional state, preceded by seizures in three cases. MRI showed focal (four patients) and diffuse (one patient) cortical hyperintensity on diffusion-weighted sequences, with a corresponding low apparent diffusion coefficient. An additional area of increased diffusion intensity was observed in the pulvinar (two patients) and hippocampus (two patients). MRI and diffusion-weighted imaging may be useful for the diagnosis of star-fruit neuro-intoxication which is associated with a poor prognosis and requires acute and appropriate treatment.

One could expect that malignant hypertension would belong to the history. Unfortunately, this complication has not been eradicated even though many physicians have already forgot it. The hypertension care units are still confronted to it, and even the arrival of the renin-angiotensin system blockers have changed the prognosis of those patients, an adequate management on emergency remains mandatory in order to avoid in particular the evolution to renal failure. By reporting a series of 42 patients included in a period of 7 years, we aimed to remind the presentation of this severe pattern of hypertension and the basics of its management.

We report two cases of community-acquired Acinetobacter baumannii pneumonia. Although most infections occur in hospitalized patients, a few cases of community-acquired pneumonia have been described. This disease occurs predominantly in men, and is often associated with underlying conditions such as cigarette smoking, alcohol abuse, diabetes mellitus, and chronic pulmonary diseases. Community-acquired Acinetobacter baumannii pneumonia cases are generally reported from tropical areas, especially during wet season. Microbiological identification in blood or sputum can be difficult because of frequent misinterpretation and possible confusion with Staphylococcus or Haemophilus infuenzae or neisseriae. Early antibiotherapy is required because of the fulminant clinical course, with approximatively 50% fatality rate.

BACKGROUND: Acute pulmonary edema may be induced by beta 2-mimetics used for tocolysis. CASE REPORT: A 41-year-old patient, admitted for preterm labor, presented acute pulmonary edema after parenteral tocolysis using salbutamol in combination with corticosteroid therapy to improve fetal pulmonary maturation. DISCUSSION: The pathogenic mechanism is essentially non-cardiologic. Fluid retention is probably the main cause, potentially worsened by corticosteroid administration. If detected early, pulmonary edema is usually and adequately treated by cessation of beta 2-sympathomimetic therapy, oxygen administration and diuretics. Mechanical ventilation can be required. Cardiac function must be assessed after this complication. In preterm labor, the duration of tocolysis with beta 2-sympatomimetics should be reduced.

This study was carried out in shrimp ponds from New Caledonia, in order to determine the cause of the exceptional proportion of abnormal tests (FAI) (often >50%, sometimes >80%). FAI was positively correlated to the quantity of easily oxidized material (EOM) deposited on the bottom of the ponds and to the sediment oxygen demand, and negatively correlated to redox. These results suggest that a very high FAI is a potential indicator for great accumulations of native organic matter, leading to a high sediment oxygen demand. When studying ancient sediments in core samples, exceptional abundances of abnormal tests may indicate periods of high accumulation of EOM, and therefore of oxygen depletion. This finding should help in better management of aquaculture ponds, but should also allow new insight into the interpretation of sedimentary records, providing a useful proxy for paleoenvironmental reconstructions.
