Phentermine is a sympathomimetic amine, like amphetamine, which is one of the most often prescribed drugs for weight loss. Although exact mechanism of phentermine causing psychosis is still not clear, numerous reports already showed that phentermine can induce psychosis. Psychotic symptoms are generally resolved once the medications are stopped. In contrast, we present a case of a 25-years-old Asian female patient who developed psychotic symptoms repeatedly after phentermine administrations. This case suggests that phentermine can cause psychotic episodes repeatedly, resulting in chronic occupational and social impairment. Therefore, a precautious measure such as government regulations for physicians prescribing and an education for patients taking phentermine are urgently needed.

The purpose of this article is to introduce a simple appliance that uses a setup model and a nickel-titanium (Ni-Ti) wire for correcting the mesial rotation and drift of the permanent maxillary first molar. The technique involves bonding a Ni-Ti wire to the proper position of the target tooth on a setup model, followed by the fabrication of the transfer cap for indirect bonding and its transfer to the patient's teeth. This appliance causes less discomfort and provides better oral hygiene for the patients than do conventional appliances such as the bracket, pendulum, and distal jet. The treatment time is also shorter with the new appliance than with full-fixed appliances. Moreover, the applicability of the new appliance can be expanded to many cases by using screws or splinting with adjacent teeth to improve anchorage.

BACKGROUND: In cirrhotic patients, left ventricular diastolic dysfunction is associated with poor outcomes. Diastolic wall strain (DWS) is a new index of left ventricular diastolic function that correlates with the myocardial stiffness. In this study, we aimed to determine whether DWS calculated from preoperative transthoracic echocardiography can predict the survival of liver transplantation recipients. METHODS: A total of 981 patients who underwent liver transplantation were enrolled. We collected the clinical, laboratory and echocardiographic data retrospectively. The left ventricular posterior wall thickness at end-systole (LVPWs) and end-diastole (LVPWd) were measured using M-mode imaging. DWS was calculated as follows: DWS = (LVPWs – LVPWd) / LVPWs. As previously reported, DWS ≤ 0.33 was defined as low DWS and DWS > 0.33 was defined as normal DWS. The primary outcome of this study was 2-years survival after liver transplantation. RESULTS: The 2-years mortality rate following liver transplantation was higher in low DWS group than normal DWS group (14.6% vs.10.0%, P = 0.038). In univariate Cox regression analysis, age, model for end-stage liver disease score, Child-Turcotte-Pugh score, creatinine, b-type natriuretic peptide, heart rate, left ventricular end-diastolic volume index, left ventricular stroke volume index, left ventricular ejection fraction, E/A ratio, e′, E/e′ ratio, and DWS were associated with 2-years survival after liver transplantation. In multivariate Cox regression analysis, DWS was an independent predictor of 2-years survival after adjusting significant univariate covariates. CONCLUSIONS: This study results indicated that the DWS is an independent prognostic predictor in liver transplantation recipients.

Thalamic pain is a primary cause of central post-stroke pain (CPSP). Clinical symptoms vary depending on the location of the infarction and frequently accompany several pain symptoms. Therefore, correct diagnosis and proper examination are not easy. We report a case of CPSP due to a left acute thalamic infarction with central disc protrusion at C5-6. A 45-year-old-male patient experiencing a tingling sensation in his right arm was referred to our pain clinic under the diagnosis of cervical disc herniation. This patient also complained of right cramp-like abdominal pain. After further evaluations, he was diagnosed with an acute thalamic infarction. Therefore detailed history taking should be performed and examiners should always be aware of other symptoms that could suggest a more dangerous disease.

Regulation of osteoblast and osteocyte viability is essential for bone homeostasis. Smad4, a major transducer of bone morphogenetic protein and transforming growth factor-β signaling pathways, regulates apoptosis in various cell types through a mitochondrial pathway. However, it remains poorly understood whether Smad4 is necessary for the regulation of osteoblast and osteocyte viability. In this study, we analyzed Smad4Δ(Os) mice, in which Smad4 was subjected to tissue-specific disruption under the control of the 2.3-kb Col1a1 promoter, to understand the functional significance of Smad4 in regulating osteoblast/osteocyte viability during bone formation and remodeling. Smad4Δ(Os) mice showed a significant increase in osteoblast number and osteocyte density in the trabecular and cortical regions of the femur, whereas osteoclast activity was significantly decreased. The proliferation of osteoblasts/osteocytes did not alter, as shown by measuring 5′-bromo-2′deoxyuridine incorporation. By contrast, the percentage of TUNEL-positive cells decreased, together with a decrease in the Bax/Bcl-2 ratio and in the proteolytic cleavage of caspase 3, in Smad4Δ(Os) mice. Apoptosis in isolated calvaria cells from Smad4Δ(Os) mice decreased after differentiation, which was consistent with the results of the TUNEL assay and western blotting in Smad4Δ(Os) mice. Conversely, osteoblast cells overexpressing Smad4 showed increased apoptosis. In an apoptosis induction model of Smad4Δ(Os) mice, osteoblasts/osteocytes were more resistant to apoptosis than were control cells, and, consequently, bone remodeling was attenuated. These findings indicate that Smad4 has a significant role in regulating osteoblast/osteocyte viability and therefore controls bone homeostasis.

T-helper (Th)17 cell responses are important for the development of neutrophilic inflammatory disease. Recently, we found that acetyl salicylic acid (ASA) inhibited Th17 airway inflammation in an asthma mouse model induced by sensitization with lipopolysaccharide (LPS)-containing allergens. To investigate the mechanism(s) of the inhibitory effect of ASA on the development of Th17 airway inflammation, a neutrophilic asthma mouse model was generated by intranasal sensitization with LPS plus ovalbumin (OVA) and then challenged with OVA alone. Immunologic parameters and airway inflammation were evaluated 6 and 48 h after the last OVA challenge. ASA inhibited the production of interleukin (IL)-17 from lung T cells as well as in vitro Th17 polarization induced by IL-6. Additionally, ASA, but not salicylic acid, suppressed Th17 airway inflammation, which was associated with decreased expression of acetyl-STAT3 (downstream signaling of IL-6) in the lung. Moreover, the production of IL-6 from inflammatory cells, induced by IL-17, was abolished by treatment with ASA, whereas that induced by LPS was not. Altogether, ASA, likely via its acetyl moiety, inhibits Th17 airway inflammation by blockade of IL-6 and IL-17 positive feedback.

The current study evaluated DSM-IV psychiatric diagnoses and investigated the psychological characteristics of sexual offenders by using the Hypersexual Behavior Inventory(HBI), Sexual Addiction Screening Test (SAST), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). Fifty male sexual offenders and 36 male healthy controls completed the psychiatric diagnosis and 30 of the 50 male sexual offenders completed the psychological tests listed above. Thirty-two of the 50 sexual offenders were patients with paraphilias, these sexual offenders had been admitted by the Ministry of Justice to the Institute for Forensic Psychiatry in Gongjui-si due to sexual violence. Participants displayed high lifetime rates of psychiatric disorders: 32 (64%) had paraphilias, 16 (32%) had depressive disorders, 10 (20%) had anxiety disorders, 9 (18%) had impulse control disorders, 6 (12%) had schizophrenia, 2 (4%) had bipolar disorders, and 16 (32%) had personality disorders or some other Axis II disorder. Scores for the sexual offenders were significantly higher both on the HBI and the SAST than the comparison group. Scores for the sexual offenders were also higher for the BDI and the BAI as compared to the control group, but this difference was not statistically significant. Results indicate that sexual offenders may have sexual addictions and be hypersexual. In addition to depressive and anxious psychopathologies, they also seem to have sexual psychopathologies. These results suggested that the psychopathology of sexual offenders may be different than that of a control group.

Epidural analgesia is frequently used for control of labor pain. Seizure of parturient could be misdiagnosed as eclampsia. A parturient presented a generalized tonic clonic seizure during first stage of labor in two and a half hour after dural puncture and epidural blood patch. She had received an emergency cesarean section under general anesthesia and had another seizure during transfer to the intensive care unit. A brain computed tomography showed intracerebral hemorrhage and pneumocephalus. After conservative treatment, she could discharge without any sequelae in 13 days. The anesthesiologists should be aware of the possibility of intracerebral hemorrhage when they confront a seizure of parturient although there is no evidence of relation between dural puncture and intracerebral hemorrhage.
