1.Observation on ventilation disorders in patients invited to the Pulmonary Department of BachMai Hospital for examining ventilating function , the year 2001
Journal of Practical Medicine 2004;480(5):14-16
In the year 2000-2001 period, at Bach Mai Hospital, 1.480 patients underwent a measuring of pulmonary ventilation function, among them 65% were under 50 years old and male/female ratio was 1:3. Initial diagnosis was bronchus asthma in 36.2%, acute bronchitis 15.4% and lung tumor 12.9%, COPD and chronical bronchitis 14.2%. In 77% of cases, FEV1 <80%. In 72% of cases, VC<80%. In 26.4% of cases, there were obstructive nervous disturbance with Tiffeneau <70%, among them 98.2% of cases were at least in medium severe level with FEV1<80%. In 32.1% of case, there was a diagnosis of asthma, 24.3% bronchitis and 65.2% COPD, there was obstructive nervous disturbance with Tiffeneau index < 70%. In 31.9% of cases there was obstructive nervous disturbance and VC < 80% concurrently.

SARS-CoV-2 variant B.1.1.7, first detected in September 2020 in the United Kingdom of Great Britain and Northern Ireland, has spread quickly to many countries around the world. While some publications have described the clinical features of adult patients with the B.1.1.7 variant, little information is available on newborn patients. We report the clinical characteristics, treatment and care practices for a 21-day-old newborn patient who was confirmed to be infected with SARS-CoV-2 variant B.1.1.7 in Viet Nam during contact tracing after her father was confirmed to be infected with SARS-CoV-2. The patient displayed no symptoms of COVID-19 on admission but 3 days later developed diarrhoea, vomiting, a runny nose and a productive cough. These symptoms lasted for 3 days before becoming milder for 1 day and then stopping until discharge. During treatment, the patient received Vietnamese traditional herbal peppermint extracts for cough and digestive probiotics for diarrhoeal symptoms. A saltwater solution (Sterimar 0.9%) was used to clean the patient’s sinuses. The patient was cared for and fed breastmilk by her mother, who was provided with personal protective equipment, including sterilized infant equipment, medical masks and hand sanitizer, during hospitalization. The patient’s mother tested negative for SARS-CoV-2 throughout hospitalization. In conclusion, we found no severely abnormal clinical symptoms in a newborn infected with SARS-CoV-2 variant B.1.1.7 during treatment. Our case suggests that newborn patients with the B.1.1.7 variant can receive exclusive breastmilk feeding if sufficient preventive measures are provided for both mother and child.

Purpose:
Laparoscopic surgery is considered a promising approach for Hartmann reversal but is also a complicated major surgical procedure. We conducted a retrospective analysis at a city hospital in Vietnam to evaluate the treatment technique and outcomes of laparoscopic Hartmann reversal (LHR).
Methods:
A colorectal surgery database in 5 years between 2015 and 2019 (1,175 cases in total) was retrieved to collect 35 consecutive patients undergoing LHR.
Results:
The patients had a median age of 61 years old. The median operative time was 185 minutes. All the procedures were first attempted laparoscopically with a conversion rate of 20.0% (7 of 35 cases). There was no intraoperative complication. Postoperative mortality and morbidity were 0 and 11.4% (2 medical, 1 deep surgical site infection, and 1 anastomotic leak required reoperation) respectively. The median time to first bowel activity was 2.8 days and median length of hospital stay was 8 days.
Conclusion
When performed by skilled surgeons, LHR is a feasible and safe operation with acceptable morbidity rate.

Background:
Viet Nam confirmed its first case of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on 23 January 2020 among travellers from Wuhan, China, and experienced several clusters of community transmission until September. Viet Nam implemented an aggressive testing, isolation, contact tracing and quarantine strategy in response to all laboratory-confirmed cases. We report the results of SARS-CoV-2 testing during the first half of 2020 in northern Viet Nam.
Methods:
Between January and May 2020, 15 650 upper respiratory tract specimens were collected from 14 470 suspected cases and contacts in northern Viet Nam. All were tested for SARS-CoV-2 by real-time RT-PCR. Individuals with positive specimens were tested every three days until two tests were negative. Positive specimens from 81 individuals were cultured.
Results:
Among 14 470 tested individuals, 158 (1.1%) cases of SARS-CoV-2 infection were confirmed; 89 were imported and 69 were associated with community transmission. Most patients (122, 77%) had negative results after two tests, while 11 and 4 still tested positive when sampled a third and fourth time, respectively. SARS-CoV-2 was isolated from 29 of 81 specimens (36%) with a cycle threshold (Ct) value <30. Seven patients who tested positive again after testing negative had Ct values >30 and negative cultures.
Conclusion
Early, widespread testing for SARS-CoV-2 in northern Viet Nam identified very few cases, which, when combined with other aggressive strategies, may have dramatically contained the epidemic. We observed rapid viral clearance and very few positive results after clearance. Large-scale molecular diagnostic testing is a critical part of early detection and containment of COVID-19 in Viet Nam and will remain necessary until vaccination is widely implemented.

Objective: At the time of this study, the prevention of novel coronavirus disease 2019 (COVID-19) relied solely on nonpharmaceutical interventions. Implementation of these interventions is not always optimal and, consequently, several cases were imported into non-epidemic areas and led to large community outbreaks. This report describes the characteristics of the first community outbreak of COVID-19 in Viet Nam and the intensive preventive measures taken in response.
Methods: Cases were detected and tested for SARS-CoV-2 by real-time reverse transcriptase polymerase chain reaction. Contact tracing and active surveillance were conducted to identify suspected cases and individuals at risk. Clinical symptoms were recorded using a standardized questionnaire.
Results: In Vinh Phuc province from 20 January to 3 March 2020, there were 11 confirmed cases among 158 suspected cases and 663 contacts. Nine of the confirmed cases (81.8%) had mild symptoms at the time of detection and two (18.2%) were asymptomatic; none required admission to an intensive care unit. Five prevention and control measures were implemented, including quarantining a community of 10 645 individuals for 20 days. The outbreak was successfully contained as of 13 February 2020.
Discussion: In the absence of specific interventions, the intensive use of combined preventive measures can mitigate the spread of COVID-19. The lessons learned may be useful for other communities.
