Detection of bifid mandibular condyle using computed tomography

Objective: To determine the frequency and characteristics of bifid mandibular condyle (BMC) using computed tomography (CT) evaluation. Study Design: A retrospective study was carried out using the CT records of 550 patients referred to the Medical School of Erciyes University (Kayseri, Turkey) between 2007 and 2010. T-tests were used to compare frequency of BMC between the left and right sides and between female and male patients. Statistical analysis was performed using SPSS software and a chi-squared test. Results: Of the 550 Patients, 10 patients (1.82%) were found to have BMCs. Five patients were female (50%) and five were male (50%). Of these 10 patients, 7 (70%) had unilateral and 3 (30%) had bilateral BMCs. As a result, a total of 13 BMCs were found in 10 patients. No statistically significant differences were found between either the right- and left-sided BMCs or between female and male patients (p >.05). Conclusions: To our knowledge, this is the first retrospective study investigating the prevalence and characteristics of BMC using computed tomography. Although BMC is an uncommon anomaly, it may be a more frequent condition in the Turkish population. Further studies and research on the orientation of duplicated condylar heads should be carried out

Primary lumbar hydatid cyst: a case report

A five-year-old male patient presented with swelling in the lumbar region that had persisted for two weeks. Ultrasonography and magnetic resonance imaging revealed a cystic lesion inside his right back muscles. Intra-abdominal organs within the site of inspection were normal. The lumbar region was explored, and a 3x4x5 cm hydatid cyst was detected inside the latissimus dorsi muscles. The cyst was incised and the germinative membrane was removed. Albendazole was used for three months after surgery to prevent recurrences. No problem was detected in a five-year follow-up period. Primary hydatid cyst in the lumbar area is very rare. In hydatid cyst treatment, it is necessary to remove the cyst without contaminating adjacent organs. Medical treatment as an adjunct to surgery increases the chance of full recovery

Value of multislice computed tomography in the diagnosis of acute mesenteric ischemia

Objective: To define the value of multislice computed tomography (CT) in the diagnosis of acute mesenteric ischemia (AMI)

Non-invasive MR imaging of human brain lymphatic networks with connections to cervical lymph nodes

Abstract Meningeal lymphatic vessels have been described in animal studies, but limited comparable data is available in human studies. Here we show dural lymphatic structures along the dural venous sinuses in dorsal regions and along cranial nerves in the ventral regions in the human brain. 3D T2-Fluid Attenuated Inversion Recovery magnetic resonance imaging relies on internal signals of protein rich lymphatic fluid rather than contrast media and is used in the present study to visualize the major human dural lymphatic structures. Moreover we detect direct connections between lymphatic fluid channels along the cranial nerves and vascular structures and the cervical lymph nodes. We also identify age-related cervical lymph node atrophy and thickening of lymphatics channels in both dorsal and ventral regions, findings which reflect the reduced lymphatic output of the aged brain

The effectiveness and safety of ultrasound guided renal biopsies Ultrason rehberliǧinde yapilan böbrek biyopsilerinin etkinlik ve komplikasyonlari

Purpose: To evaluate the effectiveness and safety of US guided renal biopsies with 16G semi-automated biopsy needles. Material and Methods: Renal biopsies obtained with 16G semi-automated biopsy needle between the years 2005-2007 were included into the study. Free hand technique under US guidance was used. The biopsies were categorized as the ones obtained from a lesion and the ones obtained for parenchymal disease. The pathology results were noted and effectiveness was calculated. Major (need for blood transfusion, radiological intervention or surgical intervention, acute renal obstruction or failure, septicemia and death) and minor (pain and hematuria) complications were noted. Results: There were 32 patients in the lesion group and 73 patients in parenchymal disease group. In five patients the biopsy material was not suitable for a pathological diagnosis. In three patients biopsies were obtained from the necrotic part of the lesion and in two patients parenchymal biopsy was inadequately obtained from the medulla. All other biopsies were sufficient and appropriate for a pathological diagnosis. So the success rate was %95,1 for all biopsies, %90,62 for lesion biopsies, and %97,26 for parenchymal biopsies. Minor complications were seen in six patients. Conclusion: Renal biopsies with 16G semi-automated biopsy needles under US guidance are effective and safe
