Ultrasound imaging is a useful technique in diagnosing CTS patients when EDT results are not confirmatory and the patient is suspected of having neuropathy.

Absconding by psychiatric patients from acute psychiatric wards has been a significant problem for some time. This study was conducted to identify the incidence rate of absconding in a psychiatric hospital and some of the characteristics of patients who had escaped from hospital in year 2006. In this descriptive cross-sectional study, all of absconds in our centre have been registered in the period of 9 months. We assessed patients' age, gender, marital status, hospital stay, substance abuse, psychiatric diagnosis and site of absconding. A total of 43 cases of absconding have been registered in this period, attempted by 35 patients, with the incidence rate of 3% in our centre. The mean age of absconders was 31.7 years; 95.3% of absconds were made by men; 67.4% were single; 37.4% absconded through the main door; 62.8% of our absconders had bipolar mood disorder or schizophrenia; mean in hospital stay before absconding was 18.4 days; and 53.5% of absconds were attempted by substance users. Absconders utilize a significant portion of hospital resources and have an adverse effect on ward milieu. It seems that the patients who are more prone to abscond are male, young, single, addict, with the diagnosis of bipolar mood disorder or schizophrenia and patients who are admitted not long ago.

Aim. To determine the level of the conus medullaris-Tuffier's line, and conus medullaris-Tuffier's line distance using imaging and evaluate their relation to age and gender. Methods. We performed a cross-sectional study of 189 adult participants, who underwent MR imaging of lumbosacral spine. Each vertebra was divided into 3 equal segments (upper, middle, and lower), and intervertebral disc space was also assumed as one segment. All segments from T12 upper segment to L5S1 intervertebral disc were numbered consecutively. The position of conus medullaris and Tuffier's line was determined by the vertebral segment or intervertebral disc space at the same level. The patients were stratified into high/low conus medullaris position (cutpoint: L1 middle segment) and short/long conus-Tuffier's distance (cutpoint: 14 segments). Results. Women with low conus were significantly more than men, in patients older than 50 years old (72.7% in females versus 55.3% in males; P < .05), whereas there was not such a sexual dimorphism in patients younger than 50 years old. Similarly, short conus-Tuffier's distance was more frequent among women than men in patients older than 50 years old (59.7% in females versus 39.5% in males; P < .05), whereas there was not any gender difference in patients younger than 50 years old. Conus-Tuffier's distance was negatively correlated with age (r = −0.32, P < .001) in all studied population. Conclusion. Anatomical landmarks vary according to age and gender, with a lower end of conus medullaris in women, so clinicians should use more caution on the identification of the appropriate site for lumbar puncture, particularly in elderly women.

Appendiceal intussusception is an uncommon form of intussusception. Most of the literature regarding appendiceal intussusception discusses the colonoscopic diagnosis or surgical treatment of the condition. Sonographic findings have rarely been described. We present a case of preoperative sonographic diagnosis of appendiceal intussusception.
