Pathergy test (PT): Sensitivity and selectivity in 544 patients with Behcet's disease (BD) and in 147 controls
Mansouri P
Tehran University Medical Journal , 1994,
Abstract: The skin hyperreactivity, detected by the pathergy test, is a well known phenomenon in Behcet's disease. Two different methods were used for the pathergy test. a) A needle prick, b) An intadermal injection of normal saline. In this study 83% of Behcet's patients had a positive pathergy test. Where as 44% was of pustule type and 39% of papule type. In 26% of patients the papule formation was observed with both methods. In the control groupe 16% of subjects had a positive pathergy test. All were of papule type . Only 3% of them demonstrated a positive reaction with both methods. The sensitivity of the pathergy test, in this study, was 83% with a specificity of 84%. From these results we may conclude that a positive pathergy test of pustule type, with one of the major manifestations of Behcet's disease, (as proposed in disease). The papule type reaction, by both methods, may have the same diagnostic value as pustule type
A case study of Impetigo
Mansouri P
Tehran University Medical Journal , 1993,
Abstract: This is a report of a case study on 234 patients with impetigo who referred to Razi Dermatology Hospital from April to November, 1989. Treatment was started immediately after obtaining direct smear and performing culture and antibiotic sensitivity test. The most common organism responsible for impetigo was the coagulase-positive staphylococcus (71%). In 13.7% of the cases, the coagulase-negative staphylococcus was grown on culture media, but none of the cultures showed streptococcus as the main organism. Treatment was started with oral penicillin V, oral erythromycin, benzathine penicillin G injection, oral cephalexin, and topical fuccidin. Clinical and bacteriological evaluation after 3-7 days showed that it is preferable to use oral cephalexin instead of other protocols such as oral erythromycin, which has previously been the drug of choice for impetigo. In addition, topical fuccidin with a 75% curative rate was the first drug for treatment, with the same effect as the oral cephalexin
A Clinical Study of the Effect of Occlusal Reduction on Pain after Endodontic Instrumentation
M - Saatchi,P Mansouri
Journal of Isfahan Dental School , 2006,
Abstract: Introduction: Pain after endodonic therapy, is of serious concern both to the dentist and patient. The aim of this study was to evaluate the effect of occlusal reduction on pain after endodontic instrumentation.Methods and Materials: In this matched clinical trial study, 98 patients were used. Each patient had a molar tooth requiring endodontic treatment. All teeth were vital, occlusion in contact and without preoperative pain or sensitivity to percussion. After access cavity preparation, teeth were divided into 2 groups: teeth with occlusion in contact and teeth with occlusal reduction. The teeth were instrumented using passive step back technique. Canals were dried and temporarily sealed. Each patient was informed and given a standard questionnaire form (Visual analogue scale). The patients recorded their degree of discomfort over a 48-h postoperative periods (0, 4, 8, 24, 32 and 48 h). Results were collected and tabulated using student t-test.Results: There were no differences in the intensity of post operative pain between two groups in each periods of the study.Conclusion: Occlusal reduction in vital teeth and without preoperative pain or sensitivity to percussion cannot decrease postoperative pain effectively.Key Words: Occlusal reduction, Postoperative pain, Percussion, Passive stepback technique, Visual analogue scale.Address: Dr. Musoud Saatchi (Assistant Professor), Department of Endodontics, School of Dentistry, Isfahan University of Medical Sciences and Health services, Isfahan, IRAN.

Mechanism for self-formation of periodic structures on a plastic polymer surface using a nanosecond and femtosecond laser pulses
Behzad Mansouri,P. Parvin
Physics , 2015,
Abstract: The high UV laser dose at 193 nm induces grooves on poly allyl diglycol carbonate PADC (CR39) at normal irradiation. The spatial period exhibits to be nearly invariant for azimuth and polar angles indicating a loose dependence on the incident angles but the LIPSS (Laser-induced periodic surface structures) are always parallel to the P polarization component of the incident beam. The most common approach to explain LIPSS formation is related to the Sipe theory which does not account for all the observed phenomena especially LIPSS with periodicity larger than the laser wavelength. In fact the LIPSS is a multi parameter mechanism based on surface rippling, acoustic modulation and laser ablation and etc. In experiment with CR-39 polymer, laser irradiation produce a very tiny melting layer of mixture of monomer due to depolymerization on the surface and it seems capillary wave is responsible for grooves formation.
Is Psoriasis an autoimmune disease?
Rafiei Sh,Mansouri P,Alavi M
Tehran University Medical Journal , 1995,
Abstract: Psoriasis is a chronic, inflammatory and proliferative skin disease that has a wide distribution throughout the world. The immune system plays a critical role in developing this disease. In this survey, we have studied 50 patients suffering from Psoriasis and 50 control subjects for various immunological factors, simultaneously. Anti-stratum corneum (SC) antibody was evaluated by immunofluorescent technique that showed a high significant level of it in patients (P<0.005). The titer of immunoglobulins (IgG, M, and A) measured by radial-immunodiffusion (RID) method was also higher in normal population. CIC estimated by PEG precipitating technique demonstrated high concentration in patients. TNF, a cytokine with strong performance to induce inflammation, had no significant rising amount in patient sera, but in synovial fluid in Psoriasis arthritis may have higher levels. We discuss that due to immunological findings we consider that Psoriasis is probably as an autoimmune disorder. The prevention, treatment and prognosis of the disease may follow the same procedures as other autoimmune diseases and further investigation will be helpful to achieve the above goal
Study of oral Ketoconazole on recurrent & extensive Pityriasis Versicolor
Moghaddami M,Mansouri P,Solaimanian F
Tehran University Medical Journal , 1997,
Abstract: Several topical agents have been used for treating Pityriasis versicolor. But the main problem is recurrence. In this study 82 patients with recurrent and/or extensive from of infection were treated with oral Ketoconazole. 200 mg once daily for a maximum of 4 weeks. Seventeen patients have been infected for the first time and sixty five for the several times. The duration of disease in most cases (35.4%) were between 1-3 years. Out of 82 studied patients only 60 cases were referred for follow up. The clinical and mycological cure were seen in 54 cases (90%) after 15 days therapy. In other 6 patients after 15 days the lesions have not cured completely so the treatment was continued for other 2 weeks, but after that, only one of them referred to the clinic, which treatment extended with topical therapy.

Z Jadali,M Izad,MB Eslami,P Mansouri
Iranian Journal of Public Health , 2007,
Abstract: Background: The aim of this study was to determine the Th1 and Th2 serum cytokines, in patients with psoriasis and to com pare their cytokine levels with those of normal control subjects. Methods: Serum levels of Interferon-gamma (IFN-γ), Interleukin-2 (IL-2), Interleukin-4 (IL-4), and Interleukin-10 (IL-10) were measured by enzyme linked immunosorbent assay in 40 patients with psoriasis and in 40 normal controls. Results: Compared with control subjects, patients with psoriasis had elevated levels of IFN-γ and IL-2 (P<0.001). In addi tion a positive correlation was found between the levels of IFN-γ, IL-2 and disease severity. Conclusion: Th1 secreting inflammatory cytokines may contribute to the pathogenesis of psoriasis.
Hepatitis C Virus Antibodies and Vitiligo Disease
Z Jadali,MB Eslami,MH Sanati,P Mansouri
Iranian Journal of Public Health , 2005,
Abstract: Vitiligo is a common skin disorder, characterized by depigmented patches due to selective destruction of melanocytes. The etiology of this disease is unknown. A number of hypotheses including viral theory have been proposed to explain the etiology. To determine the prevalence of antibody to hepatitis C virus infection in vitiligo patients, the present study was performed. Third generation ELISA test was used for detection of antibodies to HCV in human sera. All normal controls were anti-HCV negative whereas only one patient was positive for anti-HCV and there was no significant difference in the prevalence of anti-HCV between patients and controls. These results indicate that hepatitis C virus has not a direct causal role in the pathogenesis of vitiligo, however, this does not rul out a "hit and run" virus induced disease.
SCLEROMYXEDEMA
Z. Safaii Naraghi.,P. Mansouri M.R. Mortazavi
Acta Medica Iranica , 1996,
Abstract: Scleromyxedema is a rare, chronic, progressive, fibromucinous disorder of unknown etiology, characterized by lichenoid waxy papules and firm induration of skin of trunk, face, forearm and hands; fibroblast proliferation and mucin deposition in the upper dermis. Cutaneous involvement is characteristic but there are several associated systemic manifestations: We observed a case of scleromyxedema with multiple systemic manifestations including endocrinopathy and hypothyroidism. Scleromyxedema is a multisystem disorder associated with multiple organ involvement including liver, muscle, kidney and could be associated with endocrinopathies including hypothyroidism.
