A retrospective clinical study of types of myocardial infarction (MI) in 200 Libyan female patients was undertaken in Tripoli Medical Center (TMC) from January 2001 to October 2004 (4 years), with age groups between 25 years to 97 years. The results indicate that most of the patients belonged to old age group (50-79 years). Extensive and antero-septal types of MI were most common types of MI. The vast majority of the patients were post-menopausal (95%). The condition was treated mainly with analgesics (morphine), anticoagulants and vasodilators. A further study to correlate lipid profile with the menopausal status is suggested.

Hexane is an alkaline hydrocarbon with the chemical formula CH3(CH2)4CH3. n-Hexane is an isomer of Hexane. Hexane isomers are largely unreactive, and are frequently used as an inert solvent in organic reactions because they are very non-polar. They are also common constituents of gasoline and glues used for shoes, leather products and roofing. The aim of this study is to evaluate the effects of prolonged exposure to n-hexane.

Malignant chest wall tumors typically manifest as large, poorly marginated infiltrative masses and are more likely than benign tumors to be symptomatic. Although most malignant tumors have a nonspecific imaging appearance, findings such as chondroid or osteoid matrix, combined fat and soft tissue components or diffuse osteolytic change in association with a soft-tissue rib mass can be helpful in suggesting diagnosis of chondrosarcoma or osteosarcoma, liposarcoma, or multiple myeloma respectively. Changes in benign lesions such as the development of a soft tissue mass in association with pre-existing osteochondroma or the loss of a target like appearance in neurofibroma may be early indications of malignant transformation. In some patients, the combined clinical and imaging findings may suggest the diagnosis. For example, findings of chronic lymphedoema may lead to a diagnosis of angiosarcoma, or findings of a large mass with relatively minor rib involvement in a child may indicate a diagnosis of Ewing sarcoma. Even when the findings are nonspecific, imaging is important for tumor staging, therapeutic planning, and follow up of patients with malignant chest wall tumors. However, many chest wall tumors have nonspecific imaging features, and histological analysis of tissue specimens is frequently required for diagnosis. Even after the decision has been made to perform a biopsy, imaging continues to play an important role in tumor management and is frequently used to facilitate biopsy, assess post procedural complications, and perform follow-up evaluation of tumors that are not excised.

This study was undertaken to report on the oral mucosal disorder seen in a clinic that is specialized in the diagnosis and treatment of oral mucosa disease at the diagnosis clinic of oral medicine department general hospital. The initial diagnostic evaluation was carried out by a dentist and a dermatologist. When additional work was required, patient were referred for laboratory studies radiography, or consultation with other specialists.

Diffuse axonal injury (DAI) is a frequent result of traumatic deceleration injuries and a frequent cause of persistent vegetative state in patients. DAI is the most significant cause of morbidity in patients with traumatic brain injuries, which most commonly are the result of high-speed motor vehicle accidents. Axonal injury (AI) has been described as a phenomenon which can be induced as a diffuse change, i.e. diffuse axonal injury (DAI) caused by traumatic brain injury. It is only when obvious lesions are absent or minimal; the occult effect of DAI can be invoked. The aim of this study is to evaluate the vitality of the brain and approximately the survival time of rats subjected to sublethal head trauma, using some ordinary and immunohistochemical stains for the injured brains. Sixty adult male albino rats were used in this study, 8 of them were kept as a control group and the others were subjected to sublethal head trauma under light ether anaesthesia. Then they were grouped after exclusion of cases with skull fracture or intracranial hemorrhage, according to their survival time into 4 groups: group I (0—. <30 minutes), group II (0.5 hour—. <2 hours), group III (2 hours—. <4 hours) and group IV (4 hours—. < 6 hours). Sections from different brain areas were prepared with different stains and examined. Gross examination revealed peticheal hemorrhages scattered in all brains, especially brain stem compared to the control group. Microscopic examination pointed to the possibility of detecting the neuronal injury as early as 0.5-2 hours using immunoreactivity against neurone specific enolase (NSE). Also B-amyloid precursor Protein (B-APP) immunoreaction could detect the axonal injury as early as 2-4 hours. Silver stain and H & E stains could reveal these neuronal traumatic changes at later times (4-6 hours). So, immunohistochemical stains are useful to detect neuronal changes for short survivors while ordinary stains are suitable to detect neuronaj changes for victims surviving longer times after trauma. It is to be noted that the diffuse nature of these neuronal injuries is necessary for the diagnosis of traumatic head injury, since ischemic hypoxic insults can lead to localized neuronal changes. So, detection of DAI is helpful in the diagnosis of sudden obscure deaths, especially when occult head trauma is suspected.

The aim of this study is to evaluate the results of dome-shaped tibial osteotomy with mono-tub external fixator in treatment of genovarus and other tibial deformities with or without leg length discrepancy. And to understand the system of external fixator ... advantages, disadvantages and complications. And is it a better solution that replaces other methods which used in treatment of tibial deformities.

Forty five limb lengthening procedures are carried out in the Orthopedic department in Elkhadra hospital in the period between April 1995 and December 1999. Corticotomy of the bone and lengthening using Wagner distraction device. Twenty seven tibie, seventeen femura, and one humorous were lengthened. Lengthening ranged between 3cm. to 11cm. The cause of lengthening was residual poliomyelitis in 84% of the patients. In all patients the desired length was gained without any serious mechanical problems.

Benign chest wall tumors are a diverse group of lesions with vascular, neural, osseous, cartilaginous or lipomatous origins. Radiologic assessment is an essential component in the management of these tumors and usually includes the use of chest radiography to detect and localize the lesion and of cross-sectional computerized tomography (CT) and magnetic resonance (MR) imaging to further characterize the lesion and define its extent. Radiologic findings indicative of a benign tumor like the presence of a well-defined mass without infiltration of adjacent structures, or the presence of bone erosion without destruction and clinical features, such as slow growth and lack of pain, support a relatively conservative management strategy. Occasionally, benign tumors may have imaging features that are specific enough to enable immediate diagnosis and initiation of appropriate management. Such features include the presence of mature fatty tissue with little or no septation (lipoma), the presence of phleboliths and characteristic vascular enhancement (cavernous haemangioma) and evidence of neural origin combined with a target like appearance on MR images (neurofibroma). Several primary bone tumors may also have characteristic features that allow confident identification, such as well-defined cortical and medullary continuity with the bone of origin (osteochondroma) or fusiform expansion and ground-glass matrix (fibro-dysplasia). Both aneurysmal bone cysts and giant cell tumors typically manifest as expansile osteolytic lesions and occasionally show fluid-fluid levels suggestive of diagnosis.
