重度抑郁发作患者一级亲属执行功能测验初步研究

目的:探讨重度抑郁发作患者一级亲属的执行功能与正常对照组的差异。方法:采用威斯康星分类卡片测验(Wisconsin CardSorting Test,WSCT)对30名重度抑郁发作患者的一级亲属和30名健康对照者的执行功能进行评估。结果:在WSCT测验中,重度抑郁发作患者一级亲属的持续性应答数和持续性错误数、非持续错误数、完成第一个分类所需应答数明显高于正常对照;而正确应答数、概念化水平百分比均明显低于正常对照,差异具有统计学意义。结论:重度抑郁发作患者一级亲属可能存在执行功能受损,尚需进一步更严格的研究证实。     

Concerns of an Itinerant Surgeon: Results of a Guatemalan Surgical Aid Trip

Over the past decade the popularity of foreign medical aid has increased and gained notoriety. Operation Walk is a philanthropic organization dedicated to improving the ambulatory potential of patients in developing countries by providing free surgical treatment for patients who otherwise lack access to care of debilitating bone and joint conditions. During Operation Walk Mooresville's 2013 trip to Guatemala 40 patients prospectively completed a Likert Scale style survey. The 63-question survey assessed patient impressions and concerns regarding the care they receive as part of itinerant surgical aid trips. Mean scores were calculated and then concerns were ranked accordingly. We are aware of no other investigation assessing these sorts of patient centered perspectives for international surgical aid trips.     

Real time optic nerve sheath diameter measurement during lumbar puncture

Measurement of optic nerve sheath diameter (ONSD) using point of care ultrasound has been used to indirectly assess the intracranial pressure (ICP) particularly in conditions where it is raised. Direct pressure measurements using probes reaching the ventricle system correlated with ONSD using ultrasound. Attempts were made to measure the ONSD pre and post lumbar puncture (LP) after draining cerebrospinal fluid (CSF) as well as post ventricular shunt placement. We report ONSD measurement and demonstrate dynamic changes during LP in a patient with known idiopathic intracranial hypertension (IIH).     

Chronic pain related to first bite syndrome: report of two cases

First bite syndrome is the classic symptomatology of pain in the parotid region that occurs in response to the first bite of a meal. We report two cases of this syndrome in patients after operations to the parapharyngeal space.     

The phenomenology of the first panic attack in clinical and community-based samples

The purpose of the study was to contrast first panic attacks (PAs) of patients with panic disorder (PD) with vs. without agoraphobia and to explore differences between first PAs leading to the development of PD and those that remain isolated. Data were drawn from a community survey (N = 2259 including 88 isolated PAs and 75 PD cases). An additional sample of 234 PD patients was recruited in a clinical setting. A standardized interview assessed the symptoms of the first PA, context of its occurrence and subsequent coping attempts. Persons who developed PD reported more severe first PAs, more medical service utilization and exposure-limiting coping attempts than those with isolated PAs. The context of the first PA did not differ between PD and isolated PAs. PD with agoraphobia was specifically associated with greater symptom severity and occurrence of first attacks in public. Future research should validate these findings using a longitudinal approach.     

Exploratory Study of Apparent Diffusion Coefficient Histogram Metrics in Assessing Pancreatic Malignancy

PurposeTo evaluate whole-lesion 3D-histogram apparent diffusion coefficient (ADC) metrics for assessment of pancreatic malignancy.MethodsForty-two pancreatic malignancies (36 pancreatic adenocarcinoma [PDAC], 6 pancreatic neuroendocrine [PanNET]) underwent abdominal magnetic resonance imaging (MRI) with diffusion-weighted imaging before endoscopic ultrasound biopsy or surgical resection. Two radiologists independently placed 3D volumes of interest to derive whole-lesion histogram ADC metrics. Mann-Whitney tests and receiver operating characteristic analyses were used to assess metrics’ diagnostic performance for lesion histology, T-stage, N-stage, and grade.ResultsWhole-lesion ADC histogram metrics lower in PDACs than PanNETs for both readers (P ≤ .026) were mean ADC (area under the curve [AUC] = 0.787-0.792), mean of the bottom 10th percentile (mean_0-10) (AUC = 0.787-0.880), mean of the 10th-25th percentile (mean_10-25) (AUC = 0.884-0.917) and mean of the 25th-50th percentile (mean_25-50) (AUC = 0.829-0.829). For mean_10-25 (metric with highest AUC for identifying PDAC), for reader 1 a threshold > 0.94 × 10^?3 mm²/s achieved sensitivity 94% and specificity 83%, and for reader 2 a threshold > 0.82 achieved sensitivity 97% and specificity 67%. Metrics lower in nodal status ≥ N₁ than N₀ for both readers (P ≤ .043) were mean_0-10 (AUC = 0.789-0.822) and mean_10-25 (AUC = 0.800-0.822). For mean_10-25 (metric with highest AUC for identifying N₀), for reader 1 a threshold <1.17 achieved sensitivity 87% and specificity 67%, and for reader 2 a threshold <1.04 achieved sensitivity 87% and specificity 83%. No metric was associated with T-stage (P > .195) or grade (P > .215).ConclusionVolumetric ADC histogram metrics may serve as non-invasive biomarkers of pancreatic malignancy. Mean_10-25 outperformed standard mean for lesion histology and nodal status, supporting the role of histogram analysis.     

Early psychosis in Indonesia: reflections on illness and treatment

Abstract

This paper provides an overview of more than 22?years of research conducted in the central Javanese province of Yogyakarta, Indonesia, by teams of researchers associated with Gadjah Mada University and Harvard University, led by the authors of this essay. This work is placed in the context of the very limited literature on early psychosis and mental health services in Indonesia. It provides an overview of mental health services in Indonesia and of this team’s research trajectory, then addresses four key domains: the cultural phenomenology of early experiences of psychotic illness; patterns of onset, with a particular focus on extremely rapid onset psychoses; patterns of care-seeking for first episode illness; and mental health services and patterns of utilization. It then discusses the importance of rapid onset psychosis for research on early psychosis, and the question of whether collinearity of rapidity of onset and rapidity of care-seeking raises questions about the long-standing finding that a short duration of untreated psychosis leads to better outcomes. It concludes by discussing difficulties of prioritizing early intervention models in settings with very low mental health resources.
