External Component

Type IV sacrococcygeal teratoma is a rare pediatric tumor that is confined to the presacral area with no external component. The signs and symptoms often arise due to mass effect and compression of adjacent organs. Urinary retention is an uncommon presenting symptom in these patients. A wide spectrum of imaging findings may be encountered in cases with sacrococcygeal teratoma because of variability of tumor size and components. We hereby present a unique magnetic resonance urography finding in a type IV sacrococcygeal teratoma which caused bladder displacement. A meticulous and complete resection of tumor with special attention to the pelvic plexus led to preservation of normal voiding function and normal bowel function in this patient.

Background: Neurometabolic diseases are a group of diseases secondary to disorders in different metabolic pathways, which lead to white and/or gray matter of the brain involvement. </P><P> Discussion: Neurometabolic disorders are divided in two groups as dysmyelinating and demyelinating diseases. Because of wide spectrum of these disorders, there are many different classifications of neurometabolic diseases. We used the classification according to brain involvement areas. In radiological evaluation, MRI provides useful information for these disseases. Conclusion: Magnetic Resonance Spectroscopy (MRS) provides additional metabolic information for diagnosis and follow ups in childhood with neurometabolic diseases.

Presenting Symptoms

Object Neurocysticercosis (NCC) is the most common parasitic infection of the central nervous system, and its prevalence is continuing to increase in the United States. The diagnosis of intraventricular NCC (IVNCC) may be difficult, and surgery frequently fails to resolve symptoms. A retrospective review of magnetic resonance (MR) imaging characteristics and surgery-related outcomes may improve management strategies of this disease. Methods The authors report the presentations, neuroimaging characteristics, surgical management, and outcomes of 30 patients with IVNCC treated over a 10-year period (mean follow-up period 4 years). Cysts were located in the lateral ventricles (five cases), the third ventricle (five cases), and the fourth ventricle (21 cases). One patient had lesions in both the lateral and fourth ventricles. Presenting symptoms were related to hydrocephalus or mass effect from the lesions. All patients underwent computerized tomography (CT) and MR imaging of the brain. Treatment consisted of shunt implantation or primary excision of an IVNCC lesion. Outcomes after operations and reoperations were evaluated in light of enhancement characteristics on MR imaging. Computerized tomography scanning demonstrated IVNCC lesions in 10% of cases, and MR revealed lesions in 100% of cases. In patients in whom gadolinium (Gd) enhancement of IVNCC lesions was demonstrated on MR imaging, the surgery-related failure rate was higher and patients required reoperation, and in those in whom gadolinium enhancement was absent the surgery-related failure rate was lower (64 and 19%, respectively; p < 0.0002). Conclusions Magnetic resonance imaging is superior to CT scanning for detecting IVNCC lesions. The absence of pericystic Gd enhancement on MR imaging is an indication for excision of the lesions. If pericystic enhancement is present, shunt surgery should be performed, and craniotomy reserved for treatment of those patients with symptomatic lesions secondary to mass effect. A treatment algorithm based on patient symptoms, cyst location, and MR imaging Gd enhancement characteristics is proposed.

Abstract Background Antibiotic resistance in Helicobacter pylori is the major cause of eradication failure. Prevalence of H.pylori antibiotic resistance is increasing worldwide, and it is the main factor affecting efficacy of current therapeutic regimens. Our aim is to investigate H.pylori resistant patients toward Levofloxacin and detect the most effective antibiotic in eradication of H.pylori. Objective To investigate H.pylori resistant patients toward Levofloxacin including regimens and to detect the most effective antibiotic in H.pylori eradication. Patients and Methods The present study aimed to investigate the Susceptibility of Levofloxacin Resistant H.pylori in patients who had been diagnosed and received any regimen including Levofloxacin and still signs and symptoms of H.pylori infection not releaved and after proper time of stoppage of PPI and antibiotics H.pylori Ag in stool still positive at the period from January 2019 to February 2020. Results In the present study we found a wide spectrum of resistance to rates of H. pylori, from nearly negligible rates of Rifampicin (0%), Imipenem (0%), Cefotaxime (2%), Tetracycline (6%), Doxycycline(10%), and Amoxicillin(38%). To high rates resistance to Metronidazole (100%), Erythromycin (72%), Clarithromycin (68%), Azithromycin (60%), Ciprofloxacin (52%), and Levofloxacin (48%). Conclusion Helicobacter pylori is the most common chronic bacterial infection in humans. Antibiotic resistance is a major issue nowadays. Prior use of macrolide antibiotics or metronidazole appears to increase the risk of H. pylori resistance. Clarithromycin resistance appears to be an "absolute" condition that can not be overcome by increasing the macrolide dose. Levofloxacin resistance seems to be increasing. Culture and susceptibility should be done before starting second line treatment.

Occlusal stabilization appliances or splints are the most widely employed method for treatment of temporomandibular disorders (TMD). Magnetic Resonance Imaging (MRI) is the most indicated imaging modality to evaluate the components of the temporomandibular joint (TMJ). Forty patients with signs and symptoms of temporomandibular disorders were treated with splints for a mean period of 12 months, comprising regular semimonthly follow-ups. After stabilization of the clinical status, occlusal adjustments and MRI evaluation were performed. It was concluded that the success of this kind of treatment are related to the total (70%) or partial improvement (22.5%) of painful symptomatology and to the functional reestablishment of the craniomandibular complex. The MRI allowed evaluation and also the conclusion that the splints provide conditions for the organism to develop means to resist to the temporomandibular disorders by means of elimination of several etiologic factors. Moreover, after treatment the patients are able to cope with disc displacements with larger or smaller tolerance.

Abstract Photodynamic therapy (PDT) using purified hematoporphyrin derivative and stereotactic intratumorally implanted optical laser fiber(s) was used to treat patients with recurrent malignant gliomas and metastatic melanoma of the brain. Tumor response to PDT was evaluated by recording changes in the volume and pattern of tumor enhancement between computed tomographic and magnetic resonance imaging scans done before and after PDT, metabolic changes in tumor tissue by31 P magnetic resonance spectroscopy, and patient outcome. Toxicity of PDT to brain was evaluated on the basis of changes in the patients' neurological examinations and correlated with changes in brain adjacent to tumor seen on postoperative imaging studies. Dramatic tumor responses to PDT were seen in all gliomas, but no response of tumor to treatment was seen with melanoma. Transient signs and symptoms of increased peritumoral cerebral edema caused by PDT were seen in all patients. Two patients suffered permanent neurological sequelae, monocular blindness and a partial visual field defect, as a result of treatment. Two patients with recurrent anaplastic astrocytomas remain in remission at 45 and 35 weeks after PDT. We conclude that intratumoral photoradiation therapy of hematoporphyrin derivative-photosensitized malignant gliomas effectively produces necrosis of the solid component of malignant gliomas: however, intratumoral photoradiation may not reach the portion of tumor that invades normal brain.

Abstract Purpose: To evaluate the relationship between the T2 patterns of spinal cord multiple sclerosis lesions and their contrast uptake. Material and method: We retrospectively reviewed the appearance of spinal cord lesions in 29 patients (with relapsing-remitting multiple sclerosis) who had signs and symptoms of myelopathy on neurologic examination and at least one active lesion visualized on magnetic resonance examinations performed between 2004 and 2011. We correlated the T2 patterns of lesions with contrast enhancement and calculated sensitivity and specificity in predicting gadolinium enhancement. Results: Only focal patterns consisting of a lesion’s center homogenously brighter than its periphery on T2-weighed images (type I) correlated significantly with the presence of contrast enhancement (p = 0.004). Sensitivity was 0.307 and specificity 0.929. In contrast, enhancement was not significantly related to uniformly hyperintense T2 focal lesions (type II) or diffuse (type III) pattern defined as poorly delineated areas of multiple small, confluent, subtle hyperintense T2 lesions (p > 0.5 for both). Conclusions: We believe that information about the activity of multiple sclerosis spinal cord lesions in patients with myelopathy may be extracted not only from contrast enhanced, but also from non-enhanced magnetic resonance images.
