‍CT Features of Teratodermoid Tumors a Review Article & Case Presentation

Abbas Arjmandshabastari

Teratoma is pathologically defined as a tumor composed of different parenchymal tissues originated from more one germinal layer and dermoid cyst is a type of which containing only of ectodermal tissues. The most common sites of this tumor are ovary, orbit, mediastinum and brain. Nowadays these tumors are diagnosed pre-operatively with new imaging modalities such as CT & MRI and their most important features are their fat & calcium components. In this review article, 19 cases and their CT images are presented.

Spreeding And Conduction Velocities of Primary Afferent Fibres Studies on Isolated (In Vitro) Mammalian Spinal Cord

Alireza Jamshidi Fard

Wall and Shortland (1991) have shown that afferent fibres entering the cord in thoracic and lumbar roots of adult rats have branches that may penetrate up to 11 segments caudally from the root entry zone. We have investigated the extent of branching and conduction velocities of ascending and descending branches of lumbar and thoracic primary afferent in isolated spinal cords of adults hamsters (60-100g) and juvenile rats (30-46 g). Hemisected spinal cords were maintained at cold artificial cerebrospinal fluid (25-27 C) in which the Ca2+ had been replaced by Mn2+ (2mm) to block synaptic activity. Hamsters, antidromic conducted responses were obtained up to 10 segments caudal to dorsal roots T6-T7 and 17 segments rostral to L3. The mean conduction velocity was 3.7 m/s (s.e.m.& 0.4) for descending primary afferents(n=21) and 9.9 a 1.2 m/s for ascending afferents (n=26). In the rat , antidromic responses were measured over 4 segments caudal and 17 segments rostral to the L3 dorsal root. Conclusion velocities were 4.4 & 0.5 m/s and 7.7 & 0.7 m/s for descending and ascending branches respectively (n=4). The result were similar to those reported by Wall & Shortland , although the temperature. Difference between the in vitro and in vivo preparations would have resulted in approximately halving of the velocity in isolated cord preparation. The conduction velocity of descending fibres was about half fibres which may be related to size differences within the branches.

Standard Wright Tube Agglutination Cannot Evaluate Clinical Condition of Human Brucellosis

Ali Goorabchi

Diagnosis of brucellea is hand for the variations or clinical appearances to isolate of brucella from clinical samples in determined diagnosis. The main part of diagnosis is serologic studies. Syndrome has several diagnosis methods. Standard tubal wright agglutination (STA) has the most usage. Several factors are involved in final determination of wright titter. It is complicated to diagnosis. Involved factors should be control in specific conditions. It should be clarify that different conditions have difference responses.

The Study of Predisposing Factors of Low Back Pain in Patients of Orthopedics Clinics, And Nurses in Orthopedic Wards of Tehran Educational Hospitals

Shadan Pedram Razi

The purpose of this study is to determine the risk factors of back pain involved patients who come to orthopedic clinics. Findings demonstrated that factors such as age, weight, abdominal circumference, parity, exercise and posture related to back pain in both groups.

Acquired Zinc Deficiency in Breast-Fed-Infants

Sedighe Amini Ranjbar

Acquired zinc deficiency in breast-fed-infants , particularly under six MO, of age is rare except in premature infant and acrodematitis entropathica. Our case in this essay seems that after a prolonged diarrhea due to E coli has got transient zinc deficiency, that with oral zinc sulfat shows prompt clinical response in 72 hours. Therefore ihtractable "diaper rash" in a full term or preterm breast-fed-infants or in a patient with prolonged diarrhea may be due to zinc, deficiency, a therapeutic trial of zinc in a patient with high index of suspicion of zinc deficiency is a reasonable and safe.

Turner Syndrome A Case Report

Kamran Moshfegh

Turner syndrome caused by complete or relative deletion of short arm of x chromosome. Short stature, primary Amenorrhoea and gonadal disgenesis are the main signs of the syndrome, but mental retardation is not the main sign of the syndrome. There are cardiovoiscular, renal, urinary and endocrine complication in syndrome.Caryotyping should be performed to diagnose suspicious patients strogentherapy used for these patients from about 15 years old.

Tar Syndrome A Case Report

Mozhgan Hashemiyeh

TAR syndromic is a congenital amegakoryecytic thrombocytopenia with Bilateral Absence of radii. Its inheritance is autosomal – recessive, Bilateral absence of radii manifests as a shortening of the forearms and flexion at the elbows; occasionally other limb abnormalities, such as phocomelia and radial deviation, are present. Other congenital anomalies are occasionally present, such as deformity of the digities, micrognathia, disocation of the hip and congenital heart disease. Purpura may present in first few days of life or may be delayed for weeks. Hemorrhagic manifestations range from a few petechiae to severe and even fatal intracranial hemorrhage. Platelet counts are usually in range of 10,000 – 30,000/mm3. Bone marrow examination reveals myeloid hyperplasia and almost total absence of megakaryocytes. Fifty percent of patients survive to 3 years. If patients survive beyond the first year, the platelet count stabilizes and the prognosis is such better. This condition is not premalignant. Treatment consists of transfusion of red cells for anemia and transfusion of platelet concentrates for severe bleeding from thrombocytopenia. Corticosteroids and splenectomy are of no constant benefit.

A Brief Study in Islamic Medicine

Seyed Hossein Hashemi

After Greek and Alexandrin civilization was destroyed, science began to foster in Islamic civilization Among all sciences medicine was too Blossomed. Ancient texts have been translated for two centuries to follow a scientific direction. "Mohammad" The Holy prophet of Islam said that "learning science for an hour is better than seventy years of praying Besides he commanded that "Medicine is one of the essentials for muslims. Muslims believed that every doctor who does not know his duties and put his client in danger is a sinful person. Among all Muslims Iranians made the most progress. The Research in medicine extensinely included: Hygiene , Physiology , diagnosis , therapeutics & pharmacology. Muslim civilization was become weak by Mogholian invasions after many centuries. Although European made a new foundation of medicine, but every one knows that medicine is indebted to Islamic civilization.

Application of Computer in Medical Science Training

Akram Bayati

Since the computer Data Banks are developed in various courses; computer is applied and is introduced as the source and base of training devices in order to improve the level of training. Same as all other educative courses, computer is used in medical science training. Computers which are used for the purpose of training are designed base upon SKINER theories ALL activate conditional principles are applied in these type of computers. Therefor it is obvious that in accordance with experiment the certain proved effects of computer in development of training affairs and providing relative facilities can be indicated.
