A study on 76 cases have worm in bile duct at Viet Duc hospital from 1/2001 to 8/2002. The result showed that: Most of patients were from suburb of Ha Noi and other provinces with high risk of to be infected by worm. The mainly clinical symptom: pain in parasternal region with vomit, 44.6% patient without gall operation history; 29.1% with gall former operation and 26% with history of GCOM. SACL result and endoscopy in the same day to take worm out: 80.4%, without worm: 19.6%. SACL and endoscopy in other day to take worm out: 43.4%, without worm: 56.6%. GCOM is popular not only in Viet Nam but also in other under develop countries with humidity and high temperature climate. Nowadays, SACL and endoscopy to take worm out were performed at all levels. SACL has priority in diagnosis and follow up GCOM. To improve the effective diagnosis GCOM by SACL, the related factors and intervention issues need to pay attention.

A study on 41 patients with bladder cancer diagnosis in Viet Duc hospital from 3/1999 - 3/2002. The result showed that: Large tumor: 58.5%, hardening patch infiltration: 41.5%. The size of tumor changes. The density of tumor before injection taken from 35-50 HU, after injection, increase in 10-15 HU is not matched, with large mass and relative uniform in small tumors and hardening patch infiltration. Invasive operation of fatty layer around bladder: 78%; invasive sperm, prostate gland: 14.6%; ureter: 14.6%; gland: 9.8%; invasive rectum: 4.9%... Bladder cancer often occurs in male and elderly. Further diagnosis such as bladder endoscopy, UIV, ultrasound, computed tomography has value in the diagnosing and helps the physician to foresee and plan for treatment: diagnosis of operation capacity.

An analysis of 270 patients with the brain tumor with the results of pathological anatomy diagnosed by CT scanner in Viet Duc hospital during 1996 - 1997 has shown that it was not difficult to diagnose the meningeal tumor (21.9%), pituitary tumor (10.4%), craniopharyngeal tumor (4.8%) and metastatic tumor by CT scanner. But it was difficult to diagnose the spider tumor (14.8%) by CT scanner because of atypical signs.

13 patients with the gallbladder cancer diagnosed by ultrasound in which 6 patients received CT scanner, these images compared with the operational results and pathological anatomy. The gallbladder cancer occurred most frequently in the elderly and had the poor prognosis. The ultrasound showed the unfair thickness of gallbladder wall (66.7%) rough tumor from the posterior wall to gallbladder

The ultrasound Doppler and spiral CT scanner implemented in 19 patients with the abdominal aortic aneurysm have shown that the abdominal aortic aneurysm occurred most commonly in men over 60. The spiral CT scanner were frequently applied to exam before an operation because it overcome the limitations of ultrasound Doppler and angiography. In addition to, the spiral CT scanner had short time of procedure, can set up the three dimensional images with good quality which helped evaluating precisely the condition of arteries and determining the relation of the renal arterial aneurysm and discovering the renal stenosid and accessory renal stenosid as well as risks of rupture.

This study introduced the signs for identifying the pancreatic lesion due to injuries on films of CT scanner and role of CT scanner in identifying the pancreatic lesion due to close abdominal injuries. In the pancreatic injury, the X-ray and ultrasound only allowed to think of diagnosis and can not identify the lesion of pancreatic parenchyma as well as evaluate the extent of lesion, especially in emergency. When the suspected symptoms occurring, it should implement CT scanner to determine the lesion and timely manage.

The ectopic pregnancy is an obstetric emergency that needs to early diagnose and timely treat. The ectopic pregnancy can be found in the ovary, ovary tube or abdomen. The ultrasound can be implemented without needing the full urine in the gallbladder, even the uterine inclined toward the back. The results have shown that the fetal heart beat of 3/45 cases, blood aggregation in the ovary tube of 25/45 cases and fluid in the Douglas of 40/45 cases found by the ultrasound. The early diagnosis of the ectopic pregnancy can present the complication of intraabdominal bleeding from which it can be treated by endoscopy and without intervention of operation

Background: Hepatic trauma is a common disease in surgical emergency. Nowadays, there are many means of diagnostic imaging such as ultrasound, computerized tomography, magnetic resonance imaging.. but computerized tomography is more valuable in the diagnosis and treatment decisions. Objectives: To assess the value of computerized tomography in diagnosis of hepatic trauma. Subjects and method: To conduct computerized tomography on 36 patients with hepatic trauma (28 male, 8 female, aged 5-70 year olds), was diagnosed by ultrasound in Viet Duc hospital from January, 2005-June, 2005. Results: Major cause of the trauma was still due to traffic accidents (77.8%), followed by living and occupational accidents (61.5%). Using computerized tomography, there were only 12 patients undergoing surgery, the remainders were conservative treated. The common signs were: fluids in abdominal cavity: 33/36 patients (91.7%), without fluids in abdominal cavity: 3 patients. Parenchyma crush: 28/36 patients (77.8%). The most common lesion site was right liver. Diagnostic CT scans at 4 or more degrees was necessary during considering surgical indication for cases of having combined injuries, which can lead to hemodynamic dysfunction. Therefore, clinicians tend to use conservative therapy in hepatic trauma. Conclusion: CT scans was chosen as major examination to determine exactly level of lesions and to decide procedures.

Objectives: The prevalence of posttraumatic stress disorder (PTSD) has increased, particularly among individuals who have recovered from coronavirus disease 2019 (COVID-19) infection. Health literacy is considered a “social vaccine” that helps people respond effectively to the pandemic. We aimed to investigate the association between long COVID-19 and PTSD, and to examine the modifying role of health literacy in this association. Methods: A cross-sectional study was conducted at 18 hospitals and health centers in Vietnamfrom December 2021 to October 2022. We recruited 4,463 individuals who had recovered from COVID-19 infection for at least 4 weeks. Participants provided information about their sociodemographics, clinical parameters, health-related behaviors, health literacy (usingthe 12-item short-form health literacy scale), long COVID-19 symptoms and PTSD (Impact Event Scale-Revised score of 33 or higher). Logistic regression models were used to examine associations and interactions. Results: Out of the study sample, 55.9% had long COVID-19 symptoms, and 49.6% had PTSD.Individuals with long COVID-19 symptoms had a higher likelihood of PTSD (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.63–2.12; p < 0.001). Higher health literacy was associated with a lower likelihood of PTSD (OR, 0.98; 95% CI, 0.97–0.99; p = 0.001). Compared to those without long COVID-19 symptoms and the lowest health literacy score, those with long COVID-19 symptoms and a 1-point health literacy increment had a 3% lower likelihood of PTSD (OR, 0.97; 95% CI, 0.96–0.99; p = 0.001). Conclusion Health literacy was found to be a protective factor against PTSD and modified the negative impact of long COVID-19 symptoms on PTSD.
