Percutaneous drainage of abdominal abscesses and fluid collections

Abstract: This report summarizes the results of 64 percutaneous catheter drainage of abdominal abscesses and fluid collections in 56 patients. Aspiration and drainage was guided with computed tomography in 34 patients and with ultrasound in 30 patients. Success rate was 90%. Infected collections were successfully drained in 94% and noninfected collections in 72% . Partial success was achieved in two patients. Three patients failed to respond to percutaneous drainage. Recurrence occurred in one. Complications occur­ red in nine patients, two of which were major (3%) and seven were minor ( 1 1 %). Imageguided percutaneous drainage appears to be the treatment of choice for most of the intraabdominal collections. MJ/RI, Vol. 4, No.3, 177·184, 1990 Vulurnc-l Number J

Childhood respiratory tuberculosis in iran

Abstract: To estimate the bacterio-epidemiological situation of childhood re­ spiratory tuberculosis in Iran, 2185 symptomatic patients of 0-14 years old were studied. Among 110 bacteriologically confirmed cases, 60% were less than five years old and the number of females was slightly more than males. In 21 % of patients, the Mantoux test was negative. None of the miliary cases had a history of BCG vaccination. In 54.6% of patients less than two years old, one of the family members was suffering from infectious tuberculosis. Clinical findings were fever, cough, weight loss and respiratory distress respectively. Radiological findings were mostly pneumonia or bronchopneumonia-like infiltrations and in 44% of cases were found in the right lung. Mycobacterium tuberculosis strains in 11.7% of patients were resistant to isoniazid or streptomycin. MJIRI, Vol.4, No.1, 1-4, 1990

Estimating infant and child mortality in iran, 1989

Abstract: This paper presents estimates of infant and child mortality in the rural and urban areas of Iran for 1989. Data are from a one percent sample of the urban and rural population. The study makes use of data on the number of children born alive and children surviving, classified by age of the mother. Based on these data estimates of infant and child mortality for the urban and the rural areas have been calculated separately by using the Trussell version of the Brass method. The results of this study show that the infant mortality rates in the rural and urban areas of Iran are 70 and 35 per thousand, respectively. The estimates obtained from previous retrospective studies are com­ pared with the current rates. Datails of the method, limitations of the data and discussion of the results are given in the paper.

Alpha-1-Antitrypsin Types and Serum Levels in Toxoplasmosis

Abstract: α1-Antitrypsin (PI) types were studied in patients with toxoplasmosis (n = 84) and controls (n = 143) using isoelectric focusing. The patients showed a lower frequency of rare types (p

Appliance effects on the masseter and temporal muscle electromyography of patients with facial asymmetry.

Abstract: The usual symmetrical EMG recordings were disturbed in all 5 cases of asymmetrical dentofacial deformity. A marked electrical activity of the masseter and temporal muscles opposite to the site of the lesion was observed.

The isolation of enzyme transketolase from human erythrocytes: the characterization of its quarternary structure

Abstract: Human erythrocyte transketolase (sedoheptulose-7-phosphate: D-glyceraldehyde-3-phosphate, glycolaldehyde transferase, E.C. 2.2.1.1.) has been isolated from erythrocytes with a specific activity of 59.�4 U/mg. SDS-PAGE and SE-HPLC were used both as a measure of purity and as a preparative mean to obtain a higher degree of purity. Four protein bands corresponding to molecular weights of 32,000, 39,000, 43,000 and 60,000 were obtained in electrophoresis and SE-HPLC preparations. Activity measurements on the two fractions obtained from SE-HPLC that contained a monomer with the molecular weight of 32,000 and a dimeric fraction with the molecular weight of 60,000 showed that the monomeric form of the enzyme displays activity in the presence and absence of the TPP and Mg(II). This activity was measured to be 14.76 U/mg in the absence of TPP and Mg(II), and 40.24 U/mg in the presence of the cofactors. The dimeric form showed an activity of 58.84 U/mg in the presence of the cofactors. MJ/RI, Vol. 4, No.4, 293-297, 1990 Volume4

Prevalence of pityriasis versicolor in war-wounded and chemical (mustard) gas-wounded patients in iran-iraq war

Abstract: A total of 1118 soldiers who were wounded in war and hospitalized in Tehran, were examined for P .versicolor-a superficial mycotic infection. Of these, 213 were war-wounded, 54 chemical (mustard) gas-wounded, 42 both war and chemical gas-wounded, 105 had infectious and non­ infectious diseases, and 704 were apparently healthy soldiers serving in war fronts who were examined for P. versicolor and its relation with a history of contact with mustard gas. In this study the prevalence of P. versicolor among the above groups was: 7.40%, 1.85%, 9.52%, 11.42% and 6.11 % respectively. Upon microscopic examination (Scotch tape method) from hyperpig­ mented parts of the skin resulting from mustard gas, P. orbiculare (the etiologic agent ofP. versicolor) was seen abundantly. This observation leads us to hypothesize that there may be a relation between P. versicolor and previous contact with mustard gas.

SERUM 6-hCG CONCENTRATION CHANGES FOLLOWING INTRAMUSCULAR hCG ADMINISTRATION

Abstract: In circumstances such as in vitro fertilization (IVF) or in patients with luteal phase defect, one needs to ensure the establishment of pregnancy as soon as possible. At the same time, a question arises: How can a physician make sure that the B-hCG is of an endogenous source and not the residue of the prescribed drugs (hCG)? In this article we have studied the elimination time of 1M injection of 5000 IU hCG in 11 normal, and 1M injection of 5000 and 10,000 IU hCG in 11 Rokitansky patients. The time of complete elimination of B-hCG from the circulation in 10 normal women and 5 Rokitansky patients receiving 5000 IU of hCG were 7-11, and 7-8 days respectively. There was no statistically significant difference between these two groups. Comparing the two groups of Rokitansky patients receiving 5,000 and 10,000 IV ofhCG, the elimination time were dose-dependent, and were significantly different from each other (P

C-reactive protein response in angina pectoris

Abstract: C-reactive protein (CRP) response was studied in 44 patients with acute angina pectoris admitted to the coronary care unit. 71 % of patients with acute myocardial infarction (MI)had positive CRPtest while 73% of patients presumed to have unstable angina pectoris had negative CRP test. This test can be helpful in differentiating between acute MI and unstable angina pectoris. MJIRI. Vol. 4. No.2. 85-86. 1990

Plasma dehydroascorbic acid levels in iranian subjects with diabetes mellitus

Abstract: Several reports concerning high plasma dehydroascorbic acid (DHAsA) levels in diabetics have been published and from these reports, suggestions that monitoring of DHAsA levels in those persons with a predisposition to diabetes mellitus would be of value. However, conflicting reports have also appeared which do not confirm high levels of DHAsA in diabetic subjects when compared to controls. Because of these conflicting results, this investigation using Iranian diabetic subjects was undertaken to ascertain whether or not periodic monitoring of DHAsA levels would be of value as an indicator of prediabetic conditions. Our results do not confirm high levels of DHAsA in diabetics but because of the many theories concerning the mechanism of action and the metabolism of DHAsA, previous findings cannot be disregarded.
