Stress and trauma research has traditionally focused on the negative sequela of adversity. Recently, research has begun to focus on positive outcomes, specifically posttraumatic growth (PTG)-"positive change experienced as a result of the struggle with trauma"-which emphasizes the transformative potential of one's experiences with highly stressful events and circumstances. For evaluation of PTG, resilience is very important. Resilience refers to a person's ability to successfully adapt to acute stress, trauma or more chronic forms of adversity, maintaining psychological well-being. This article introduces several measurement scales for assessment of PTG and resilience. In addition, we suggest psychological techniques for facilitating PTG focusing on the relationship with adaptation after trauma. Finally, we discuss the applicability of a therapeutic approach for PTG in clinical practice. The systemic review of this article will provide further directions for PTG and resilience.

PURPOSE: The SPAN, which is acronym standing for its four components: Startle, Physiological arousal, Anger, and Numbness, is a short post-traumatic stress disorder (PTSD) screening scale. This study sought to develop and validate a Korean version of the SPAN (SPAN-K). MATERIALS AND METHODS: Ninety-three PTSD patients (PTSD group), 73 patients with non-psychotic psychiatric disorders (psychiatric control group), and 88 healthy participants (normal control group) were recruited for this study. Participants completed a variety of psychiatric assessments including the SPAN-K, the Davidson Trauma Scale (DTS), the Clinician-Administered PTSD Scale (CAPS), and the State-Trait Anxiety Inventory (STAI). RESULTS: Cronbach's alpha and test-retest reliability values for the SPAN-K were both 0.80. Mean SPAN-K scores were 10.06 for the PTSD group, 4.94 for the psychiatric control group, and 1.42 for the normal control group. With respect to concurrent validity, correlation coefficients were 0.87 for SPAN-K vs. CAPS total scores (p<0.001) and 0.86 for SPAN-K vs. DTS scores (p<0.001). Additionally, correlation coefficients were 0.31 and 0.42 for SPAN-K vs. STAI-S and STAI-T, respectively. Receiver operating characteristic analysis of SPAN-K showed good diagnostic accuracy with an area under the curve (AUC) of 0.87. The SPAN-K showed the highest efficiency at a cutoff score of 7, with a sensitivity of 0.83, a specificity of 0.81, positive predictive value (PPV) of 0.88, and negative predictive value (NPV) of 0.73. CONCLUSION: These results suggest that the SPAN-K had good psychometric properties and may be a useful instrument for rapid screening of PTSD patients.

Mindfulness is a process in which all thoughts, feelings, sensations, and all phenomena that happen to me are uncritically recognized as they are, so that they are eventually accepted and released without identifying or automatically responding to them. The clinical effects of mindfulness-based therapy have already been demonstrated in several studies. However, consistent results have not been reported for the mechanism of mindfulness-based treatment. Thus, this review aimed to describe a systematic review of the literature and research on the mechanisms of mindfulness-based interventions. Experienced meditators showed a physiological change in a ‘wakeful hypometabolic state’ during mindfulness meditation. In mindfulness meditation, it is known that certain areas other than brain activation during relaxation are additionally activated, particularly activation of fronto-limbic and fronto-parietal neural networks. The psychological mechanisms include meta-cognitive awareness, emotion regulation, reduction of automatic and self-referential thinking, concentration control, self-compassion, improvement of value clarification and self-regulation, exposure, extinction, and reconsolidation. Of the brain regions with changes in activity associated with mindfulness meditation, prefrontal cortex, the default mode network including cortical midline structures were associated with emotion regulation, concentration control, and reduction of automatic and self-referential thinking. In addition, brain regions associated with mindfulness meditation have been reported in the hippocampus, amygdala, and medical frontal cortices associated with memory reconsolidation and fear extinction. Thus, mindfulness-based interventions have a psychological and neurobiological effect with a special mechanism different from other psychological interventions, so that mindfulness based intervention can be an effective therapeutic intervention with a different mechanism from other psychological techniques.

Strabismus is defined as an ocular misalignment. Since it can cause not only impaired visual function but also social handicap and tremendous emotional stress, the care of patients with strabismus should include psychological and social aspects. Although strabismus is one of the major fields in pediatric ophthalmology and neuro-ophthalmology, its precise mechanism and etiology are still unknown. It can be inherited from strabismic parents, or be derived from the anomalous structure, neurologic deficits, and refractive errors. The diagnosis of strabismus can be made by covering one eye, and the degree of strabismus can be quantified by the alternate prism cover test. Recently MRI is used widely for the diagnosis of various anomalous orbital and muscular structures, especially to investigate heterotopia of extraocular muscle pulley. The treatment modalities for strabismus are either surgical or nonsurgical. Surgical treatments can be made by recession or resection of the involved extraocular muscle. The adjustable suture technique was introduced in 1970s, which has been the gold standard among surgical treatment modalities. Nonsurgical treatments include prism, glasses, bifocal lenses, and drugs. A young strabismic patient may have amblyopia and decreased stereoacuity due to abnormal interaction between the sound eye and the deviating eye. Once amblyopia is detected, immediate treatment is needed to correct the visual dysfunction. Recent efforts to elucidate the mechanisms of strabismus are believed to unravel the mysterious pathophysiology in the near future.

Although autopsy studies suggest that malignant pericardial effusion is present in up to 15% of the patients suffering with malignancies, symptomatic pericardial effusion presenting as a first manifestation of systemic recurrence in a breast cancer patient is a rare condition. Symptomatic malignant pericardial effusion requires prompt attention and intervention since it can lead to the cardiac tamponade. Treatment of symptomatic pericardial effusion includes pericardial decompression and systemic or intrapericardial chemotherapy. We recently experienced a patient with early breast cancer who developed cardiac tamponade from malignant pericardial effusion as a first manifestation of systemic recurrence 4 years after her initial surgery. The patient was treated with percutaneous pericardiocentesis and she subsequently received systemic trastuzumab. After 6 cycles of trastuzumab, the follow-up CT showed complete disappearance of the pericardial effusion and the mediastinal lymph nodes.

BACKGROUND: Sleep disturbance and depression are becoming more recognized as important symptoms among individuals with chronic low back pain. This study evaluated the effect of stabilization exercise on pain-related disability, sleep disturbance and the psychological status of patients with non-specific chronic low back pain (NSCLBP). METHODS: A total of 26 patients (M/F = 17/9) with NSCLBP with a mean age of 50.0 ± 15.5 took part in this study. Participants were recruited from selected hospitals in Lagos state. Ethical approval was sought and obtained from the health research and ethics committee of Lagos University Teaching Hospital Idi-araba, Lagos, Nigeria. Participants performed stabilization exercise for eight weeks consecutively and were assessed for pain-related disability, anxiety, depression, and sleep disturbance using the pain-disability index, hospital anxiety and depression scale, and the insomnia severity index at baseline, the 4th week, and the 8th week, post-intervention. RESULTS: The participants studied recorded significant reduction in pain-related disability (P = 0.001). There was also improvement in the sleep quality (P = 0.001), depression level (P = 0.001), and anxiety level (P = 0.001), post intervention. CONCLUSIONS: This study revealed that stabilization exercise is very useful in the management of sleep disturbance, pain-related disability, depression, and anxiety in NSCLBP patients.

OBJECTIVETo investigate the effects of prenatal stress (PNS) on kinetic properties of high-voltage-activated (HVA) Ca(2+) channel in freshly isolated offspring rat hippocampal CA3 pyramidal neurons.

METHODSThe pregnant rats were exposed to restraint stress, and the hippocampal CA3 pyramidal neurons were freshly isolated from the offspring rats to record voltage-gate Ca(2+) channel currents in these neurons using whole-cell configuration of patch-clamp technique.

RESULTSPNS significantly increased HVA calcium current density and integral current but did not alter the steady-state activation and steady-state inactivation properties of HVA Ca(2+) channel in the offspring rat CA3 neurons. The maximal HVA calcium current density was -40.89-/+0.31 pA/pF in the control group (n=10) and -49.44-/+0.37 pA/pF in PNS group (n=8, P<0.01). The maximal integral current of the HVA Ca(2+) channel was 106.81-/+4.20 nA*ms in the control group (n=10) and 133.49-/+2.59 nA*ms in the PNS group (n=8, P<0.01).

CONCLUSIONMaternal exposure to stress during the critical phase of pregnancy may result in long-lasting effects on the ion channels of the hippocampal neurons in the offspring rats.

The purpose of this study was to investigate the effect of rigidity of post core systems on stress distribution by the theoretical technique, finite element stress-analysis method. Three-dimensional finite element models simulating an endodontically treated maxillary central incisor restored with a zirconia ceramic crown were prepared and 1.5 mm ferrule height was provided. Each model contained cortical bone, trabecular bone, periodontal ligament, 4 mm apical root canal filling, and post-and-core. Six combinations of three parallel type post (zirconia ceramic, glass fiber, and stainless steel) and two core (Paracore and Tetric ceram) materials were evaluated, respectively. A 50 N static occlusal load was applied to the palatal surface of the crown with a 60degrees angle to the long axis of the tooth. The differences in stress transfer characteristics of the models were analyzed. von Mises stresses were chosen for presentation of results and maximum displacement and hydrostatic pressure were also calculated. An increase of the elastic modulus of the post material increased the stress, but shifted the maximum stress location from the dentin surface to the post material. Buccal side of cervical region (junction of core and crown) of the glass fiber post restored tooth was subjected to the highest stress concentration. Maximum von Mises stress in the remaining radicular tooth structure for low elastic modulus resin core (29.21 MPa) was slightly higher than that for high elastic modulus resin core (29.14 MPa) in case of glass fiber post. Maximum displacement of glass fiber post restored tooth was higher than that of zirconia ceramic or stainless steel post restored tooth.

OBJECTIVE: The impact of maternal stress on pregnancy outcome has been a focus of research and cortisol is known as a biomarker of psychological stress. The aim of this study is to evaluate the relationship between salivary cortisol levels and pregnancy outcomes prospectively. METHODS: The subjects of this study were healthy pregnant women who collected morning samples of saliva (10~12 AM) at 10~13, 20~23 weeks of gestation, and postpartum 2 days between April 2007 to March 2008. Saliva was collected with commercial collector, Salivette(R), and cortisol level was analyzed by enzyme immunoassay. They also underwent ultrasonographic examination of umbilical and uterine artery Doppler between 20~23 weeks of gestation. Statistical analysis was assessed between salivary cortisol levels and pregnancy outcomes, including Doppler findings. RESULTS: A total 39 pregnant women collected salivary cortisol as indicated. They showed increase in cortisol level in 2nd trimester compared to 1st trimester, which decreased after delivery. Salivary cortisol level was not associated with maternal age, parity, occupation, body mass index, blood pressure, delivery mode, fetal sex, and fetal weight. However higher cortisol level was associated with lower resistance index of uterine artery, even there was no statistical significance. CONCLUSION: Our data could not show any association between salivary cortisol levels and pregnancy outcomes. Although this study presents a number of methodological and conceptual challenges, this does not necessarily preclude the use of salivary cortisol measures, but rather point to the importance of careful research design.

Multiple measurements of nocturnal penile tumescence and rigidity (NPTR) are widely accepted as a method to differentiate psychogenic erectile dysfunction (ED) from organic ED. However, direct evidence remains limited regarding the first-night effect on NPTR measurement using the RigiScan. Here, we evaluated the first-night effect on the results of NPTR measurement to validate the necessity of NPTR measurement for two consecutive nights, particularly when abnormal first-night measurements are recorded in a laboratory setting. We retrospectively reviewed 105 patients with a complaint of ED, who underwent NPTR measurement using the RigiScan in the Department of Infertility and Sexual Medicine, the Third Affiliated Hospital of Sun Yat-sen University (Guangzhou, China), for two consecutive nights, during the period from November 2015 to May 2016. NPTR parameters were collected and analyzed. We found that more effective nocturnal erections were detected during the second night than during the first night (P <0.001). Twenty percent of all patients had no effective erection during the first night, but exhibited at least one effective erection during the second night. The negative predictive value of NPTR measurement during the first night was 43.2%; this was significantly lower than that on the second night (84.2%; P = 0.003). Most NPTR parameters were better on the second night than on the first night. The first-night effect might be greater among patients younger than 40 years of age. In conclusion, two consecutive nightly measurements of NPTR can avoid a false-abnormal result caused by the first-night effect; moreover, these measurements more accurately reflect erectile capacity, especially when the first-night record is abnormal in a laboratory setting.
