The study on 6 cases of pyelonephritis of yellow granulatio at Hue Central Hospital showed a majority of female patients (2/3 of cases) aged 50-60 years old), having classic trilogy of great kidney with calculus and loss of function. Patients were admitted because of lumbago in 2/3 of cases. Urimia, fever and purulent fistula at lumbar side, each 1 case; large kidney touched in 1/2 of cases. Unprepared abdomen X ray image, UIV and ultrasound had found calculus in 1/2 of cases, 1/4 with pyhydrostasis, 3/4 loss of function. Especially color Doppler ultrasound found kidney arterio venous communicatio fistula in 1/2 of cases. CT scanning showed 6/6 cases with fat structure in the kidney parenchyma, 5/6 with large shade kidney, irregular border and heterogenous stain absorption.

Objective: We conducted a multicenter study aimed to determine the sensitivity and the specificity of clinical signs of bronchiectasis in comparison with high-resolution computed tomography (HRCT) findings. Subject and method: 82 patients (60 males and 22 females) with clinical symptoms and chest X-rays findings of bronchiectasis. All participants underwent HRCT with 1-2 mm collimation. The clinical signs of bronchiectasis were correlated with findings on the HCRT imaging, the sensitivity (Se) and the specificity (Sp) of each method were calculated. Results: HRCT findings showed that the simple bronchiectasis occupied in 39% and combined with emphysema in 61% of cases. All patients had symptoms of bronchiectasis, included cough with sputum in 82% (Se 97.5%, Sp 16.6%); hemoptisis in 52.80% (Se 65.8%, Sp 85.3%); dysapnea 28.1% (Se 33%, Sp 72%); chest pain 33.70% (Se 33%, Sp 8.5%). The combination of crackle, rhonchus and wheeze in 28% patients produced Se (35.6%) and Sp (87.8%) higher than that of other authors. This related to bronchiectasis in patients with chronic obstructive pulmonary disease in our group study. Conclusion: The abnormalities revealed by HRCT produced the sensitivity of 98% and the specificity of 99% in bronchiectasis diagnosis, so HRCT seems to be very useful for evaluate bronchiectasis.

39 patients with the clinical feature, X-ray and respiratory functional test suggested the bronchodilatation and alveolar dilatation received the spiral CT scanner with the high resolution. The results found that the spiral CT scanner with high resolution allowed evaluating the diffusion level and bronchial lumen and the wall of brachial as well as surrounding alveolus. The spiral CT scanner with the high resolution in the diagnosis of bronchodilation has a high sensitivity (91%) and the specificity (100%) comparing with the standard lung X-ray and conventional CT scanner.

During 4/1998 -4/1999, the HuÕ Central Hospital implemented the spiral CT scanner for 8 cases with ages of 17 - 79 to diagnosed the renal arterial stenosid after implementing the ultrasound Doppler and angiography of the renal artery. The result have shown that the spiral CT scanner is able to discover the spited artery with the very thin wall and observe the false arterial lumen and virtual arterial lumen. The cross-sectional reconstruction can identify obviously the border of the arterial lumen, position of stenosid, artherosclerosis plaque, thrombosis that helped the diagnosis and treatment.

Geographical and racial factors constitute important distinctions between Kawasaki disease (KD) and multisystem inflammatory syndrome in children (MIS-C), but no study has been conducted in Vietnam. Forty-one children with KD from January 2018 to July 2020 and 42 with KD/MIS-C from August 2020 to December 2022 were included in this study. Of the patients, 52.3% were aged between 12 and 35 months. Only two were aged over 5 years, and both were belong to the KD/MIS-C group. A 59.5% of the patients were male. Apart from fever, all symptoms tended to be more frequent in patients with KD/MIS-C. The prevalence of diffuse skin rash, hand and foot edema or erythema and gastrointestinal signs was significantly higher in patients hospitalized with KD/MIS-C. There was no significant difference in laboratory findings between the two groups. Coronary artery dilation was more frequently observed in patients with KD/MIS-C compared to those with KD (40.5% vs. 14.6%, P = 0.009).

Sphaeranthus africanus is commonly used as a traditional remedy for sore throats and pain treatment in Vietnam. The aerial parts have been studied for its anti-inflammatory and anti-proliferative properties. However, the antioxidant and antidiabetic potential of the plant has not been explored. In this work, hydrophilic extracts of the plant's aerial parts were prepared in order to investigate its antioxidant and anti-diabetic properties. Also, the cytotoxicity of the root was evaluated and compared to that of the aerial parts. All of the extracts inhibited lipid peroxidation with IC 50 values ranging from 2.05 to 3.56 µg/mL, indicating substantial antioxidant activity. At an IC 50 value of 4.80 μg/mL, the 50% ethanol extract exhibited the most potent inhibition of α-glucosidase. The cytotoxic activity of root extracts is 2 to 5-fold less than that of the aerial parts. Nevertheless, dichloromethane and ethyl acetate extracts of the root demonstrated a selective effect on leukemia cells, with no harm towards the normal HEK-293 cell line. This work provides a scientific support for the antioxidant and antidiabetic activity of the plant. Hence, it may find a promising material for the development of novel antioxidant and antidiabetic agents. More research can be conducted on the phytochemistry and anticancer activities of the plant’s root.
