ABSTRACT The coronavirus disease 2019 (COVID-19) outbreak in Wuhan, China, spread rapidly throughout China and gradually to some countries abroad. How is the development of an epidemic controlled? Early diagnosis is one of the important contents in prevention and control. COVID-19 patients with early mild pneumonia often lack typical evidence to make a definitive diagnosis. Based on the analysis of the cases of 4 patients, this article finds that early diagnosis requires a combination of epidemiology, clinical manifestations, imaging, and etiology, with particular emphasis on epidemiology history and chest computed tomography (CT) manifestations.

RESUMOIntrodução: A Granulomatose de Wegener (GW) é uma vasculite rara e idiopática associada à presença do anticorpo Anticitoplasma de Neutrófilo (ANCA) que acomete, preferencialmente, os pequenos vasos. As manifestações clínicas são diversas, ocorrendo em mais de 90% dos casos, sintomas do trato respiratório. O comprometimento renal é tardio e preditor de mau prognóstico.  Sua morbidade a médio e longo prazo inclui insuficiência renal crônica. A probabilidade de sucesso de manutenção da função renal depende da concentração sérica de creatinina ao início do tratamento, o que indica a importância do diagnóstico e terapêutica adequada precoces. Casuística: Relata-se o caso de uma paciente do sexo feminino, 61 anos, portadora de GW com comprometimento renal avançado à apresentação não precedido por sintomas pulmonares esperados. O tratamento imunossupressor associado a plasmaferese permitiu a melhora da função renal da paciente poupando-a de tornar-se dialítica- dependente. Discussão: A paciente iniciou a doença através de insuficiência renal assintomática, com valores de função renal compatíveis com o estágio mais avançado de doença renal crônica, ultrassonografia dos rins sem alterações compatíveis e sem os sintomas respiratórios esperados. Segundo a literatura, a combinação de imunossupressores e plasmaferese associa-se à recuperação renal em três meses com sobrevivência sem necessidade de diálise por 12 meses, no caso relatado, obteve-se tal resultado em 22 dias sem a necessidade de diálise após um ano. Conclusão: Devido ao diagnóstico precoce, o tratamento adequado foi instalado rapidamente proporcionando à paciente um aumento da expectativa e da qualidade de vida, evitando dependência de terapia renal substitutiva.Palavras-Chave: Granulomatose de Wegener, Plasmaferese, Doença renal crônica.  ABSTRACTIntroduction: The Wegener's Granulomatosis (WG) is a rare and idiopathic vasculitis associated with the presence of Antineutrophil Cytoplasmic Antibody (ANCA), that affects, preferentially, the small vessels. The clinical manifestations are diverse, occurring in over 90% of cases, symptoms in the respiratory tract. Kidney damage is a late and bad prognostic predictor. Morbidity in the medium and long term includes chronic renal failure. The probability of renal function maintenance success depends on serum creatinine concentration at the beginning of treatment that indicates the importance of early diagnosis and deployment of an appropriate therapy. Case Report: We present a case of a 61-year-old female patient, carrier of GW with advanced renal impairment presentation, not preceded by expected pulmonary symptoms. The immunosuppressive treatment associated with plasmapheresis allowed the improvement of the patient’s renal function, saving her from becoming dialysis-dependent Discussion: The patient developed the disease through asymptomatic renal failure, renal function with values that are compatible with the most advanced stage of chronic kidney disease, ultrasound of the kidneys without compatible changes and without the expected respiratory symptoms. According to the literature, the combination of immunosuppressive drugs and plasmapheresis is associated with renal recovery in three months with survival without dialysis for 12 months. In this case, a result was obtained in 22 days without the need for dialysis after one year. Conclusion: Due to the early diagnosis, appropriate treatment was quickly installed giving the patient increased life expectancy and quality, preventing dependence on renal replacement therapy.Keywords: Wegener’s granulomatosis, Plasmapheresis, Chronic renal failure.

Background: COVID-19 developed into a global pandemic in 2020 and poses challenges regarding the prevention and control capabilities of countries. A large number of inbound travelers from other regions could lead to a renewed outbreak of COVID-19 in the local regions. Globally, as a result of the imbalance in the control of the epidemic, all countries are facing the risk of a renewed COVID-19 outbreak brought about by travelers from epidemic areas. Therefore, studies on a proper management of the inbound travelers are urgent.Methods: We collected a total of 4,733,414 inbound travelers and 174 COVID-19 diagnosed patients in Yunnan province from 21 January 2020 to 20 February 2020. Data on place of origin, travel history, age, and gender, as well as whether they had suspected clinical manifestations for inbound travelers in Yunnan were collected. The impact of inbound travelers on the local epidemic was analyzed with a collinear statistical analysis and the effect of the control measures on the epidemic was evaluated with a sophisticated modeling approach.Results: Of the 174 COVID-19 patients, 60.9% were not from Yunnan, and 76.4% had a history of travel in Hubei. The amount of new daily cases in Yunnan was significant correlated with the number of inbound travelers from Hubei and suspected cases among them. Using Susceptible–Exposed–Infectious–Recovered (SEIR) model analysis, we found that the prevention and control measures dropped the local R0 down to 1.07 in Yunnan province.Conclusions: Our preliminary analysis showed that the proper management of inbound travelers from outbreak areas has a significantly positive effect on the prevention and control of the virus. In the process of resettlement, some effective measures taken by Yunnan province may provide an important reference for preventing the renewed COVID-19 outbreak in other regions.

ABSTRACT Maxillary canine and first premolar transposition is a complicated dental anomaly to treat, especially if the clinician's goal is to orthodontically move the canine into its normal position. Early diagnosis with cone-beam computed tomography simplifies the treatment of this pathology. This case report describes a patient with bilateral transposition, one complete and the other incomplete, involving the maxillary canine and the first premolar (Mx.C.1P). The orthodontic treatment involved the correction of both transpositions. In the complete transposition, the traction was mesial and upward to move the canine into a more apical position with a wider dentoalveolar process for easier crown interchange.

Rhinofacial entomophthoromycosis is an uncommon chronic fungal infection of the head and neck. The diagnosis is usually based on clinical manifestations; however, diagnosis of this infection based on early manifestations is difficult and occasionally rhinofacial entomophthoromycosis is mistaken for other diseases. Therefore, computed tomography is introduced to support the diagnosis. Radiologic findings were nonspecific with swelling of the sinonasal mucosa and perinasal region. However, subcutaneous calcification, that was observed in all our cases, may be a supportive radiologic evidence for diagnosis. The diagnosis should be confirmed definitively using histopathology or fungal culture. Early diagnosis allows prompt and appropriate treatment that will achieve excellent outcomes. We suggest that subcutaneous calcification radiologic finding may guide the aware physician to an early diagnosis of rhinofacial entomophthoromycosis.
