Effectiveness of continuous hypertonic saline infusion with an automated infusion pump for decompressive neuroplasty: a randomized clinical trial / 대한통증학회지

BACKGROUND: Hypertonic saline (HS) injections for decompressive neuroplasty (DN) can cause pain. We assessed whether a continuous infusion of HS through an infusion pump would reduce injection-related pain compared with repeated bolus administrations. METHODS: Fifty patients scheduled for DN were randomized to either the bolus injection or the continuous infusion group. After appropriately placing the epidural catheter, 4 mL of 5% NaCl was injected as four boluses of 1 mL each at 15-minute intervals or infused over 1 hour using an infusion pump. The severity of pain induced by HS injection, as measured by the 11-point numerical rating scale (NRS), was the primary outcome. The severity of low back or lower extremity pain, as measured by the 11-point NRS and Oswestry Disability Index (ODI), 3 months following the procedure, was the secondary outcome. RESULTS: Data from 21 patients in the bolus group and 23 in the continuous infusion group were analyzed. No statistically significant difference in injection-related pain was identified between the two groups during the initial HS administration (P = 0.846). However, there was a statistically significant reduction in injection-related pain in the continuous infusion group compared to the bolus injection group from the second assessment onwards (P = 0.001, < 0.001, and < 0.001, respectively). No significant between-group differences in the NRS and ODI scores 3 months post-procedure were noted (P = 0.614 and 0.949, respectively). CONCLUSIONS: Our study suggests that administering HS through a continuous infusion is a useful modality for reducing HS injection-related pain during DN.

Posterior Ring Apophysis Fracture Associated with Lumbar Disc Herniation Treated by Immobile Bony Fragment Excision: A Case Report

STUDY DESIGN: A case report. OBJECTIVES: We report a case of posterior ring apophysis fracture (PRAF) with lumbar disc herniation treated by immobile bony fragment excision. SUMMARY OF LITERATURE REVIEW: PRAF causes severe radiculopathy, so treating with surgery is common. MATERIALS AND METHODS: A 30-year-old male diagnosed with PRAF with lumbar disc herniation was treated with discectomy, but his clinical symptoms were not relieved. Consequently, bony fragment excision, extended laminectomy and interbody fusion were also done. RESULTS: Radicular pain was relieved and showed good clinical outcome. CONCLUSIONS: When treating PRAF, bony fragment excision and extended laminectomy should be considered even if an immobile bony fragment exists.

Evaluation of Pedophilia Patients of the National Forensic Hospital by Types of Offense according to the Federal Bureau of Investigation (FBI) Typologies of Child Molesters / 대한법의학회지

This study aimed to classify individuals who had perpetrated child sexual abuse according to the Federal Bureau of Investigation (FBI) typologies of child molesters and to assess the correlations between sociodemographic and criminal variables. We examined a total of 26 patients diagnosed with pedophilia (DSM-IV-TR criteria) who had been hospitalized in the National Forensic Hospital for Cure Custody. Data were obtained through self-administered questionnaires and reviews of patient records. Patients were classified into preferential offenders or situational offenders based on FBI typologies. Current and first offense ages of preferential offenders were younger than those of situational offenders. Preferential offenders were more likely to have been exposed to sexual abuse during childhood, and were more likely to watch child pornography than situational offenders (p < 0.05). Additionally, recidivists had lower IQs (intelligence quotient), lower levels of education, and longer illness durations than first-time offenders (p < 0.05). A multiple logistic regression analysis revealed that IQ and duration of illness might be risk factors of recidivism, although results were not statistically significant (p < 0.1). We found that classification of individuals who had sexually abused children into preferential or situational types, based on FBI typologies, provided on pedophile characteristics and probability of recidivism. We highly recommended that low IQ patients receive intensive treatment and education in order to reduce the possibility of future offenses.

Heme-binding-mediated negative regulation of the tryptophan metabolic enzyme indoleamine 2,3-dioxygenase 1 (IDO1) by IDO2

Indoleamine 2,3-dioxygenases (IDOs) are tryptophan-catabolizing enzymes with immunomodulatory functions. However, the biological role of IDO2 and its relationship with IDO1 are unknown. To assess the relationship between IDO2 and IDO1, we investigated the effects of co-expression of human (h) IDO2 on hIDO1 activity. Cells co-expressing hIDO1 and hIDO2 showed reduced tryptophan metabolic activity compared with those expressing hIDO1 only. In a proteomic analysis, hIDO1-expressing cells exhibited enhanced expression of proteins related to the cell cycle and amino acid metabolism, and decreased expression of proteins related to cell survival. However, cells co-expressing hIDO1 and hIDO2 showed enhanced expression of negative regulators of cell apoptosis compared with those expressing hIDO1 only. Co-expression of hIDO1 and hIDO2 rescued the cell death induced by tryptophan-depletion through hIDO1 activity. Cells expressing only hIDO2 exhibited no marked differences in proteome profiles or cell growth compared with mock-transfectants. Cellular tryptophan metabolic activity and cell death were restored by co-expressing the hIDO2 mutant substituting the histidine 360 residue for alanine. These results demonstrate that hIDO2 plays a novel role as a negative regulator of hIDO1 by competing for heme-binding with hIDO1, and provide information useful for development of therapeutic strategies to control cancer and immunological disorders that target IDO molecules.

Preliminary Study of Effect of Leuprolide Acetate Treatment on Sexual Fantasy of Sex Offenders / 대한법의학회지

This study investigated the effect of leuprolide acetate treatment on sex offenders' sexual fantasies and behaviors, as well as on their criminogenic psychological character and the risk of second conviction. The study participants consisted of 22 sex offenders who were confined to the National Institute of Forensic Psychiatry. Among them, 9 patients were given off-label leuprolide acetate for three months to inhibit sexual impulses, whereas the others were not given any medication. All sex offenders underwent two psychological evaluations; the first evaluation was conducted before starting medication, and the second was conducted after medication. Wilson's Sex Fantasy Questionnaire (WSFQ), the Rape Myth Acceptance Scale (RMAS), and the Endorsement of Violence Scale (EVS) were used for evaluation. Leuprolide acetate-treated sex offenders showed a statistically significant decline in the total WSFQ score (p < 0.05). However, the RMAS and EVS scores did not differ after leuprolide acetate treatment, indicating that cognitive distortions like rape myth acceptance and endorsement of violence were unchanged after leuprolide medication. Leuprolide acetate may reduce deviant sexual impulses and fantasies, as suggested by previous research form Korea and other countries. However, it probably cannot alter cognitive distortion. On the basis of these findings, we recommend a combination of leuprolide medication and other therapies, like cognitive behavioral therapy, for the treatment of paraphilic sex offenders.
