RESUMO
Patients with COVID-19 can require radiological examination, with chest CT being more frequent than neuro-imaging. The objective is to identify epidemiological, clinical and radiological factors considered as predictors of neurological involvement in patients with COVID-19 assessed by neuroimaging and to describe the neuroimaging findings. This retrospective study was performed with 232 consecutive confirmed COVID-19 patients, from two radiological units, which were divided into two groups: (1) those who underwent a brain CT/MRI scan (n = 35) versus (2) those who did not undergo the brain CT/MRI scan, but underwent only chest CT (n = 197). There was a statistically significant difference with associations regarding the COVID-19 brain scan group for: admission to ICU, greater severity of lung injuries, the use of a mechanical ventilator and sepsis. Statistical tendency was found for chronic renal failure and systemic arterial hypertension. Forty-percent of COVID-19 patients from the brain scan group were abnormal on brain CT and/or brain MRI (22.9% of the cases with bleeding or microbleeding, 8.6% with restricted diffusion lesions). One ischemic stroke case was associated with irregularity at the M1 segment of the right middle cerebral artery. There was a case of left facial nerve palsy with enhancement of the left geniculate ganglia. An analysis of the olfactory bulbs was possible in 12 brain MRIs and 100% had enhancement and/or microbleeding. In conclusion, a more severe COVID-19 disease from ICU, a more severe form of lung disease, the use of mechanical ventilator and sepsis were associated to the COVID-19 patients with neurological involvement who had undergone brain scans. Microvascular phenomenon was a frequent finding in the brain and olfactory bulbs evaluated by neuroimaging.

BACKGROUND: Assessment of severe maternal morbidity is increasingly being undertaken to understand the aetiology and factors which lead to adverse maternal outcomes. Their use in conjunction with maternal deaths may allow a comprehensive assessment of care provided, highlight areas for improvement within the health system and allow benchmarking of care against other institutions. Timor-Leste has one of the highest rates of maternal mortality in the Asia-Pacific region; however, there has been limited research into the level of severe obstetric morbidity in the country. AIM: To determine the aetiology and rates of severe obstetric morbidity and mortality at Hospital Nacional Guido Valadares, Timor-Leste. METHODS AND MATERIALS: Cases of maternal 'near misses' and deaths were prospectively identified over a period of 12 months using the World Health Organization maternal near-miss criteria. Cases of maternal death and near miss were combined (severe maternal outcomes) for descriptive analysis. RESULTS: During the audit period, 69 severe maternal outcomes were identified: 30 maternal deaths and 39 'near misses'. The maternal mortality ratio and the maternal near-miss ratio were 662/100 000 live births and 8/1000 live births, respectively. The main identified obstetric aetiologies were haemorrhage and pre-eclampsia, while 22% of severe maternal outcomes did not have a clearly identified cause. CONCLUSION: The high institutional maternal mortality ratio requires urgent attention and identification of areas for improvement. Auditing and benchmarking using the WHO near-miss criteria provide a mechanism for standardised comparison of obstetric care but require further refinement to the local context.

Cleidocranial dysostosis is a rare genetic syndrome with an autosomal dominant inheritance pattern. The most common manifestations include clavicular aplasia or hypoplasia, open fontanelles and abnormal dentition. The present report describes two familial cases whose late diagnosis was made by means of clinical and radiographic findings. The treatment was radical, with complete surgical teeth extraction and making of total dental prosthesis.
