    Early brain tumor diagnosis has a significant role in reducing the risk of disease, as well as led to get better treatment results. Usually, magnetic resonance imaging (MRI) images are evaluated manually through visual inspection, which is difficult, time-consuming and often erroneous;this process is performed by radiologists or clinical experts, and its accuracy depends on their experience. Recently, computer-aided diagnosis (CAD) becomes very essential to overcome these limitations. This paper provides a comprehensive assessment of the existing techniques and methodologies for automated detection of brain tumor coupled with oedema detection methods utilisation, with an emphasis on machine learning models. Moreover, this paper provides an analysis of the integrated procedure that pertains to the retrieval of brain pictures by identifying particular data sets in the procedure to recognise the stipulated attributes

    Lemon Myrtle (Backhousia Citriodora) Leaf Extract on Biofilm Formation of Pseudomonas Aeruginosa

    This study includes 10 samples isolated from a different source. This research paper was to study the antibacterial activity and antibiofilm activity of an alcoholic extract of Lemon Myrtle (Backhousia citriodora) leaves, against 10 clinical isolates of Pseudomonas aerogenoza.  Isolates were diagnosed by the VITEK-2 compact system and (PCR). The capacity of isolates to produce biofilm was tested by using the Microtiter plate technique (96 wells). The results showed that isolates were able to form a biofilm, also the ability of  Backhousia citriodora was been effective on bacteria and biofilm formation

    This research aimed to study the antibacterial activity and Antibiotic effect of hot aqueous extract of leaves of Ziziphus spina Christy (Sidr),against clinical isolate of Staphylococcus wernari. four isolates were initially diagnosed as Staphylococci bacteria, then one isolation was chosen depending on its sensitivity  and resistance to several different types of antibiotics. The VITEK-2 compact system (ID and AST) and PCR were used to confirm the type of staphylococcal isolates . The results showed that one isolate was due to Staphylococcus wernari.  the ability of isolate to form biofilm was tested using the Microtiter plate method (96 wells). The results indicated that the extracted isolate was able to produce a biofilm. Where there was a clear effect of moxifloxacin and penicillin G with (MIC), (Sub-MIC) and (Sub-MIC) in inhibiting the growth of bacteria, A significant (P < 0.001).Synergistic effect between Penicillin G, Moxifloxacin with (MIC), (Sub-MIC) and (Sub-MIC) were tested with hot aqueous extract of Ziziphus spina christi (Sidr) leaves with 50 mg/mL. The results showed a high synergy between two types of antibiotics and plant extracts

    Tangential gunshot wound to the head: A case report with review of literature

    No full text
    Introduction. Tangential gunshot wounds (TGSW) to the head is the high-velocity bullet that does not penetrate the cranium but passes through the tissue adjoining the cranial cavity, creating a “gutter” wound and indirectly causing cerebral injury. This article presents a reporting case of TGSW to the head, discusses the mechanism underlying this traumatic injury and the possible complications resulting from it, and reviews of literature.  Case description. A thirteen-year-old schoolboy was admitted to the emergency department (ER) of the neurosurgery teaching hospital in Baghdad, Iraq, with a tangential gunshot to the head of an unknown source during civilian protests in Baghdad. In addition to a seizure attack in the ER, his Glasgow coma (GCS) scale was 13 initially. The computed tomography showed multiple bilateral brain contusions, interhemispheric haemorrhage, partially depressed fracture of the frontal bone midline, and a Paramedian to the left with a significantly depressed skull fracture. Then, an urgent decompressive craniectomy was performed. The postoperative course was uneventful, with rapid improvement in GCS of 15 one hour after surgery. On the six-month follow-up, the patient reported no further attacks of seizure. Conclusion. TGSWs are associated with good GCS and favourable prognosis in most cases unless the patient has been deteriorating or has an associated ICH. Moreover, in our case, the history taking, mechanism of the injury, rapid evolution, and radiological imaging have an essential effect on the outcome

    Enlarged anterior communicating artery masquerading as intracranial aneurysm: Case report

    No full text
    Background. The anterior communicating artery (ACoA) complex consists of the ACoA, the pre-and post-communicating segments of the anterior cerebral artery, and the recurrent artery of Heubner. It is the most common site for anatomical variations in the circle of Willis. Such variations can mimic intracranial aneurysms. Case description. A 30-year-old female presented with recurrent episodes of extreme headache and bilateral tinnitus. A brain computed tomography (CT) scan showed no significant lesions, while her CT-angiography (CTA) showed an enlarged vascular lesion at the ACoA, raising the suspicion for an ACoA aneurysm. A repeated CTA revealed a rare anatomical variation with a pattern of cross dominance in the ACoA complex; the left A1 and right A2 were dominant-enlarged, resulting in an enlargement of the ACoA. The presence of an ACoA aneurysm was hence excluded and the patient was managed conservatively. At 6-month follow-up, CTA showed no new findings.  Conclusion. ACoA enlargement can result from unequal hemodynamics around the ACoA complex, which may be mistaken for an aneurysm. A thorough study of the imaging data is of pivotal importance and may change the management strategy
