Our study included 14 patients admitted to Bachmai hospital because of headache and hypertension after taking anti-cold preparations (Rhumenol Decolgen, Decolsin, and Medicoldac) from 3/2002 to 6/2002. These patients had no history of hypertension and took antiflu tablets according to instruction of manufacturers. On admission, all patients had hypertension with the maximum BP 190/120mmHg. The first-degree atrioventricular block was observed in 1 case. The adverse effects may be caused by overdose of phenylpropanolamine, a sympathomimetic agent. Our study is a warning of dangerous reality of broadly advertising, marketing and abusing drugs. The manufacturers should consider the amount of Phenylpropanolamine in anti-cold preparations to avoid the adverse effect.

The aim of this study is to describe some maxillary sinuses parameters of Vietnamese adults by multislice computed tomography from January 2005-June 2005 at the Post and Telecommunication No2 hospital. Results: jaw cavity have horizontal diameter of 3.177cm, pre- rear diameter 3.99cm, top-bottom diameter 3.9517cm… Besides the anatomical description characteristics, the initial results of this study are very important to endoscopic surgery via nasal sinus.

Diarrhea continues to be one of the most common causes of morbidity and mortality among infants and children in developing countries. Escherichia coli are an emerging agent of pathogens causing diarrhea. Among 587 fecal samples from Vietnamese children under five years of age with diarrhea, the PCR technique identified 68 samples (11.6%) positive with EAEC and 18(7.2%) among the 249 age-matched controls showing the significant difference. In the diarrhea group, the significantly higher prevalence was seen in the children less than two years of age as compared to the older ones. There is a decreasing tend of EAEC infection during the age. When comparing the children at the age of less than 12 months, the prevalence of EAEC was significantly higher in the diarrhea group than in the control. More studies need to be carried out to verify the role of EAEC in causing diarrhea in children.

Study on adults patients who were multislice computed tomography of craniofacial at the Post and Telecommunication N02 hospital from January to June 2005. In 51 cases there were 22 males and 29 females, age from 22-56 years. 102 sinuses were studied. Results: the diameters of sphenoidal sinus were measured by the greatest diameter with 3 Sagittal Coronol and Axial planes. The general size of sphenoidal sinus: horizontal diameter 1.932 cm, anterio-posterio diameter 2.347 cm, superio-posterio diameter 2.483 cm, superior-inferior diameter 3.156 cm, capacity 3.727 cm3. The technique of multislice computed tomography was the basis and necessary technique not only for diagnosis but also for the base of services in treatment.

212 patients suffering from colorectal cancer are analyzed, the author have following remarks: 1. Colorectal cancer generally occurs in individuals 40 years of age or older. Ration of men to women: 1.82. 2. Incidence of malignant lesion: rectum 36.32%, sigmoid: 16.04% righ colon: 15.57%, left colon: 14.15%, tranverse colon: 8.02%, cecum: 9.09%. 3. Treatment: right hemicolectomy 20.75%, left hemicolectomy: 7.55%, colectomy: 14.62%, subtotal colectomy: 2.83%, miles: 14.15%, artificial anus: 30.19%, by-pass: 3.77%, exploration: 1.42%. The early results of post operative: post operative complications were: 8.9%; post operatative: post operative mortality was:1.98%.

This retrospective study was undertaken to characterize the endoscopic and histopathologic pattern of patients with gastro-esophageal reflux with esophagistis. We investigated 58 patients (24 women, 34 men: mean age 44.33 years). The histopathologic pattern was classified in 3 grades: Grade 1: 19 patients, grade 2: 18 patients, grade 3: 21 patients. The sex ratio, age, endoscopic and particular histopathologic pattern was discussed. We conclude that the gastro-esophageal reflux disease is a common complaint in adult population. Despite it is not a severe damage, it can complicate to Barret’s oesophagus, a premalignant lesion of esophageal adenocarcinoma.

In a consecutive series of 860 patients undergoing surgery for gallstones, 214 patients (24.9%) were aged over 65 years, of whom 93 (43.5%) were males and 121 (56.5%) were female. Choledochotomy and removes stones with T tube drainge: 54 (25%), choledochotomy and removed stones with cholecystectomy: 34 (15.9%), open cholecystectomy: 40 (18.7%), laparoscopic cholecystomy; 42 (19.6%), cholecystostomy: 12 (5.6%), open biliary surgery with other surgery: 32 (15%). Laparoscopic cholecystectomy offers advantages over the open technique by reducing wound infections as well as the other complications; a shorter hospital stay, a rapid return to full activities.

On 97 cases treated in the Military Hospital No108, the remarks are as follows: 1) Rectal cancers occurred mainly in the age ranged 40-60 years old, men to women ratio is 1.85. 2) Clinic symptoms include constipation, diarrhoea with blood and pus occurred alternatively, tenesmus… 3) Most of tumors located at the lower rectal ampulla; adenoepithelioma accounted for 93.2%. 4) Rectal resection with sphincter conservation performed on 4.1%; Mile's operation on 59.8%; and palliative operation on 38.1% of cases; bleeding complication happened on 4.1% of cases and the most common post operative complication was perineum infection 26.8%. 5) Mortality 6.2%. 6) More than 5 years survival 52.3%

From the review of 620 cases with acute appendicitis, the author has shown that: 1. Abdominal pain is present in all patients with appenditis, the initial position of pain is difference: in the epigastrium (17.42%) or around the umbilicus (30.16%); the right lower quadrant (41.45%); the pain becomes steady: 77.58%. The pain in the right lower quadrant when palpation pressure is exreted: 80%, the rebound tenderness: 52.42%. The pain in the position of the appendix is the most important symptom for operation. 2. There was a 3.8% rate of negative appendectomies. The rate of late diagnosis is 16.55%. 3. Laparoscopic appendectomy offers advantages over the open technique by reducing wound infections as well as the other complications and a possible earlier return to normal activities. A laparoscopic procedure also allows complete evaluation of the abdominal cavity without an extension of the incision.

In study series of author, the incidence of acute appendicitis in older patients is 8.57%. The classic symptoms such as pain, anorexia and nausea presented in older patients but are less pronounced than in younger adults. Pain in the right lower quadrant: 80.95%, localization occurs later than in younger patients. 42 (85%) patients have comorbidity. In older patients with appendicitis, the diagnosis is often delayed with 66.66% of cases have been perforated. The mortality rate is 3.57%. Rate of complications is 50%. The most common complication is infection, occurred in 38.09% of patients.
