Noonan syndrome is characterized by short stature, typical facial dysmorphology, and congenital heart defects. The main facial features of Noonan syndrome are hypertelorism with down-slanting palpebral fissures, ptosis, and low-set posteriorly-rotated ears with a thickened helix. The cardiovascular defects most commonly associated with this condition are pulmonary stenosis and hypertrophic cardiomyopathy. Other associated features are webbed neck, chest deformity, mild intellectual deficit, cryptorchidism, poor feeding in infancy, bleeding tendency, and lymphatic dysplasias. The patient is a 10-year-old boy. He had experienced repeated febrile convulsions. He had typical facial features, a short stature, chest deformity, cryptorchidism, vesicoureteral reflux, and mental retardation. His language and motor development were delayed. When he went to school, it was difficult for him to pay attention, follow directions, and organize tasks. He also displayed behavior such as squirming, leaving his seat in class, and running around inappropriately. Clinical observation is important for the diagnosis, so we report a patient who was diagnosed with Noonan syndrome, mental retardation, and attention-deficit hyperactivity disorder.

An 8-year-old female with Tourette Disorder (TD) was treated with a daily oral dosage of 5 mg of aripiprazole, which did not significantly improve her symptoms. After treatment with 10 mg daily for 3 days, she experienced an acute episode of dystonia with facial muscle spasms, opisthotonus, and torticolis. All symptoms resolved after ingestion of a total of 2 mg of benztropine over 2 days. Previously, aripiprazole was considered to cause few anticholinrgic, antiadrenaline, or antihistamine effects or extrapyramidal symptoms. However, extrapyramidal symptoms have now been reported in patients with TD and in adolescent patients with other psychiatric disorders. We reviewed the literature, and to the best of our knowledge, this is the first report of a child TD patient with acute dystonia. Although the recommended treatment largely precludes acute dystonic reaction, aripiprazole has produced this reaction.

Tourette syndrome consists of multiple motor tics and one or more vocal tics. Psychopathology occurs in approximately 90% of Tourette syndrome patients, with attention-deficit/hyperactivity, mood, and obsessive-compulsive disorders being common. Additionally, Tourette syndrome and bipolar disorder may be related in some individuals. However, it is unclear why bipolar disorder may be overrepresented in Tourette syndrome patients, and more research is needed. Herein, we report the case of a 15-year-old boy diagnosed with both Tourette syndrome and bipolar disorder, whose symptoms improved with aripiprazole, atomoxetine, and valproate. The patient was diagnosed with Tourette syndrome at 8 years of age when he developed tics and experienced his first depressive episode. The patient had a poor response to a variety of antidepressants and anti-tic medications. A combination of valproate and aripiprazole stabilized both the patient's tics and mood symptoms. It is important to assess individuals with Tourette syndrome for other disorders, including bipolar disorder. The treatment of children and adolescents with both Tourette syndrome and bipolar disorder is an important clinical issue.

OBJECTIVES: The aims of this study were to explore ways in which social adjustment (SA) is enhanced and to investigate the structure of relationships among mental health state (MHS), the de-velopment of personal skills (DPS), and the development of environmental resources (DER) through structural equation modelling. METHODS: The research data were gathered by collecting self-administered questionnaires from 689 service users recruited from 62 mental health organizations in South Korea. RESULTS: Firstly, in the result of path estimates of measurement and theoretical model, especially MHS, the DER had a significant effect on the SA, the DER had a significant effect on the DPS, and the DPS had a significant effect on the SA. In contrast, MHS showed no significant effect on the DPS, and the DER showed no significant effect on the SA. Secondly, MHS and the DPS had direct effects on the SA, while the DER had indirect effects on the SA. Finally, the DER full mediating effects of between MHS and DPS ; another full mediating effects of DPS between DER and SA. CONCLUSION: Several intervention strategies for improving social adjustment were identified and presented. I found that much of your results section was difficult to understand without access to your full paper. For example, I have no details of your theoretical model and was unsure what form of structural equation modeling you used. My editing, especially of the way in which you reported your results, may therefore be inaccurate and certainly less helpful than I would have liked. Please accept my apologies for this.

OBJECTIVE: To examine gender differences in the characteristics of suicidal behavior in South Korea. METHODS: Between August 2003 and December 2006, 344 suicide attempters (116 men, 228 women) participated in this study. The attempters were interviewed using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), and the lethality of the attempt was measured using the Lethality Suicide Attempt Rating Scale-II (LSARS-II) and Risk-Rescue Rating Scale (RRRS). RESULTS: Significantly more women than men were admitted to emergency rooms due to attempted suicide during the study period. The male attempters were older and had a higher rate of employment than the females. Depression was the most common psychiatric disorder in both genders. The lesion/toxicity scores of the RRRS indicated that the male suicide attempters used higher doses or more toxic agents than the female attempters. The most common methods of suicide were ingestion and cutting in both sexes. Although there were significant gender differences in the RRRS risk score and RRRS total scores, there was no gender difference in the LSARS-II scores, which suggests that patients of both sexes share a similar ambivalence regarding suicide completion or death. CONCLUSION: Our study should be understood within the context of the specific cultural background of South Korea. We found that males and females use similar methods when attempting suicide and share a similar ambivalence regarding the outcome of the attempt; however, there was a difference in severity of the attempt between the two groups. Our findings may aid in the identification of more effective methods of intervention to prevent suicide.

OBJECTIVES: To investigate the role of ATP-sensitive potassium channel (KATP) during sustained ventricular fibrillation (VF), the effects of gliburide, a specific blocker of KATP channel and PCO400, an KATP opener, were studied in isolated and perfused swine right ventricular free walls (n=). METHODS: Recording of single cell transmembrane potentials was performed and constructed action potential duration restitution (APDR) curve by plotting APD 90%(APD90) versus preceding diastolic interval (DI). RESULTS: All isolated tissues fibrillated spontaneously. In this preparation, stable VF could persist over a 4-hour period if it was allowed to continue undisturbed (n=). Gliburide (1-5 uM) increased DI without significant changes in APD90 during VF, resulting in more regularization of VF. Higher concentration (10-20 uM) increased both APD90 and DI, and converted to monomorphic ventricular tachycardia (MVT) through the transitional period characterized by APD alternans. PCO400 (1-2.5 uM) caused a significant shortening of APD during MVT and a period of APD alternans became more evident before conversion from MVT to VF. Gliburide eliminated profibrillatory effect of PCO400. This antifibrillatory action of gliburide was accompanied by gradual decrease in the maximum slope of APDR curve during VF. CONCLUSION: KATP channel blockade causes a transition from VF to MVT via lengthening of DI and APD alternans, concomitantly with a reduction of the slope of APD restitution curve.

OBJECTIVES: Several lines of evidence suggest the serotonergic dysfunction involved in the biological susceptibility of suicide. Tryptophan hydroxylase (TPH), the rate-limiting enzyme in the biosynthesis of serotonin, plays a vital role in serotonin metabolism. In a case-control study, we investigated whether the TPH gene was a susceptible factor for suicidal behavior in depressive patients. METHODS: The subjects were 218 depressed patients who attempted suicide and visited emergency rooms in multi-medical centers. One hundred thirty hospitalized non-suicidal depressed patients and the 161 normal controls were matched with the suicidal group. Individuals in all 3 groups were evaluated independently by a Structured Clinical Interview for the purpose of establishing a DSM-IV criteria diagnosis (SCID). The severity of depressive symptoms was evaluated using Hamilton depression rating scale (HDRS). RESULTS: There was no significant difference in genotype distributions and allele frequencies of TPH intron 7 A218C polymorphisms among 3 groups. Furthermore, no significant difference in genotype counts and allele frequencies of the polymorphisms was found among lethal suicidal depressed patients, non-suicidal depressed patients and the normal controls. CONCLUSION: This study suggests that the A218C polymorphism of the TPH gene is unlikely to have a major effect on the susceptibility of suicidal behaviors in depressive patients.

Escitalopram is one of the most popular selective serotonin reuptake inhibitors (SSRIs) in current use as a first-line treatment for depression. Escitalopram is well-tolerated and rarely associated with serious side effects. Endocrine and reproductive side effects of serotonergic antidepressants are uncommon and galactorrhea is very rarely mentioned among SSRI-related side effects. Serotonin-enhancing antidepressants may result in a rise in prolactin levels through suppression of dopamine neurotransmission. In the present study, we report a case of hyperprolactinemic galactorrhea associated with escitalopram. A 36-year-old woman developed galactorrhea after initiation of escitalopram for depression and was found to have an elevated prolactin level. Escitalopram was discontinued with resolution of the patient's galactorrhea and normalization of her prolactin level.

Major depressive disorder, especially in later life, has heterogeneous clinical characteristics and treatment responses. Symptomatically, psychomotor retardation, lack of energy, and apathy tends to be more common in people with late-onset depression (LOD). Despite recent advances in psychopharmacologic treatments, 20% to 30% of patients with mood disorders experience inadequate responses to medication, often resulting in a trial of electroconvulsive therapy (ECT). However, the therapeutic mechanism of ECT is still unclear. By using ¹⁸F-fluorodeoxy-D-glucose positron emission tomography-computed tomography (18F-FDG PET/CT), we can obtain the status of brain metabolism in patients with neuropsychiatric disorders and changes during psychiatric treatment course. The object of this case report is evaluating the effect of ECT on brain metabolism in treatment-refractory LOD by PET/CT and understanding the mode of action of ECT. In this case report, we presented a 55-year-old female patient who suffered psychotic depression that was resistant to pharmacological treatment. Several antidepressants and atypical anti-psychotics were applied but there was no improvement in her symptoms. The patient presented not only depressed mood and behaviors but also deficit in cognitive functions. We found decreased diffuse cerebral metabolism in her brain ¹⁸F-FDG PET/CT image. ECT resulted in amelioration of the patients' symptoms and another brain PET imaging 7 weeks after the last ECT course showed that her brain metabolism was normalized.

OBJECTIVES: Recently, polymorphisms of several serotonin genes have been suggested to be associated with suicide, but the results are still unclear. We examined whether the T102C polymorphisms of the serotonin 2A receptor gene and the G861C polymorphisms of the serotonin 1B receptor gene were associated with suicidal behavior using drug intoxication. METHODS: The subjects were 52 patients who visited emergency room with suicidal behaviors. Fifty controls were selected from healthy volunteers matched for sex and age to the suicide subjects. The polymorphisms were analyzed with TaqMan(R) assay using primers based on previous studies. RESULTS: The T102C polymorphism of the serotonin 2A receptor gene showed no significant difference between the suicidal attempters and controls in both genotype and allele frequency analyses(p=0.179 and p=0.422, respectively). There was no statistically significant difference between the suicidal attempters and the controls in the G861C polymorphism of the serotonin 1B receptor gene and any significant effect of the genotype distributions or the allele frequencies was not observed(p=0.092 and p=0.987, respectively). CONCLUSION: These findings suggest that the T102C polymorphism in serotonin 2A receptor gene and the G861C polymorphism in serotonin 1B receptor gene are not related to the susceptibility to suicide attempts using drugs. To clarify the genetic influences of the serotonergic system on suicidal behavior, the polymorphisms of other candidate genes in the serotonergic system should be studied with larger numbers of subjects.
