Acute MI is a very significant health problem leading to an important mortality and morbidity. Due to identification and modification of its risk factors, it can help to decrease its effects. We had conducted this prospective observational study in the CCU at Zliten Teaching Hospital aiming to determine the risk factors and anatomical distribution of acute non-fatal MI in Zliten area. Zliten area has a population of 184884 according to the 2006 consensus. Died cases on arrival or within 24 hours from admission were excluded from our study.

The main aim of this study was to compare the performance of unenhanced spiral CT to the combination of MR urography (MRU) and plain abdominal radiography (KUB) in patients suspected of having acute calculus ureteric obstruction. 64 patients with suspected acute calculus ureteric obstruction were evaluated. The presence of perirenal fluid, presence and level of ureteric obstruction and calculi were assessed on both techniques. 44 out of 64 (69%) patients had acute calculus ureteric obstruction based on clinical, radiographic or surgical findings. MRU showed perirenal fluid in acute ureteric obstruction (77%) with a greater sensitivity than CT showed stranding (45%). The combination of fluid and ureteric dilation on MRU showed a sensitivity of 93% (CT 80%), specificity of 95% (CT 85%), and accuracy of 94% (CT 81%). KUB showed ureteric calculi in 21/29 (72%) of patients with calculi seen by CT. Overall, MRU/KUB revealed 2.4 abnormalities per acutely obstructed ureter compared with 1.8 abnormalities detected by CT. MRU/KUB using HASTE sequences can diagnose the presence of acute calculus ureteric obstruction with similar accuracy to spiral CT. This technique has less observer variability and is more accurate than CT in detecting evidence of obstruction such as perirenal fluid.

Most of the ophthalmologists make the diagnosis of a lump (mass), nodule, ulcerative nodule, cyst or a lesion for any abnormal tissue proliferation as a provisional clinical diagnosis. In many cases, the histopathological diagnosis supports the clinical diagnosis. Most of the excised lesions are not sent for further evaluation histologically. This retrospective study aimed to evaluate the histopathological reports of samples that were surgically excised in the Ophthalmology Department, Misurata Teaching Hospital and examined at the Histopathology Department at the same hospital. The total number of samples were 65 samples. Squamous cell papilloma were the commonest tumour (17 cases, 26%), followed by basal cell carcinoma (11case, 17%). In the age group ? 5 years, 3 out of 4 cases were examined highly malignant tumours. It is highly recommended to examine histologically any sample by excised surgically, even if the diagnosis is clear in clinical, otherwise few cases with dangerous diseases are going to be missed.

Nanoparticle are as solid particles or particulate dispersions with a size in the rang of 10-1000 nm. As the blood brain barrier is the complex in nature only lipophilic drug can cross it.Nanoparticle of polyactide (PLA) or pegylated PLA or PGLA or copolymer have safe administration profile. Pegylated PLA nanoparticles have PLA/PGLA hydrophobic core and hydrophilic PGA outer shell. Poly ethylene glycol (PEG) have conformation brush like only reduce phagocytosis and lead prolonged blood residence time of nanoparticles. Various conventional drugs e.g. savoxepine, doxorubicin, irinotecan, paclitaxel, antiestrogen, tyrphostin, lidocaine, propranolol hydrochloride, heparin, and enalaprilat can be formulated as nanoparticle. Entrapment of hydrophilic drugs may be a challenge due to the drug diffusion from the inner to the outer aqueous phases promoted by the large surface area developed. Drugs with intrinsic pharmacological activities only formulated with nanoparticle. Releases last from a few hours or a few days to several weeks. Peptides, polypeptides, and protein drugs formulated in nanoparticles is the most promising and challenging due to their hydrosolubility, chemical instability or chemical reaction, exposure to damaging conditions. Many types of nanoparticles which cross blood brain barrier. In this study, we emphasizes various strategies to prepare the nanoparticle to cross the blood brain barrier.

The most common cyst occurs in the popliteal region is the popliteal cyst and over the past years it has been received much clinical attention. The most common position of the popliteal cyst is in the posterosuperior aspect of the medial femoral condyle. The present paper describes a rare case of popliteal cyst, which was found in the postero-superior aspect of the lateral condyle of the femur. Interestingly, there are fewer reports of popliteal cysts occurring in the postero-superior aspect of the lateral condyle. We as orthopedic surgeons describe the unusual presentation of popliteal cyst in the postero-superior aspect of the lateral popliteal region and discuss its clinical significance. Anatomical knowledge of such anomalies is very important.

Class III malocclusion can be classified as dentoalveolar, skeletal or functional, which will determine the prognosis. The aim of this article was to describe and discuss a clinical case with skeletal Class III malocclusion treated with frankle 3 appliance and fixed mechanotherapy and followed up for two years.
