The value of CT and very low field MRI in the etiological diagnosis of dizziness

A total of 79 dizziness patients were examined by either computed tomography (CT), or very low field magnetic resonance imaging (MRI), or both. In most cases, the patients were selected for the neuroimaging because preliminary clinical examination had suggested central nervous system (CNS) involvement. Abnormal CT or MRI findings with probable clinical relevance to the etiology of dizziness were obtained in 34%. The most common abnormalities were atrophy, infarction, and demyelination.; 29% of the CT scans and 40% of the MRI showed relevant abnormalities. The present results emphasize the diagnostic usefulness of head CT and MRI when dizziness of CNS etiology is suspected.     

The Relationship Between Psychogenic Cough and the Diagnosis and Misdiagnosis of Asthma: A Review

The differential diagnoses of persistent nonproductive cough include numerous pulmonary and nonpulmonary organic disorders as well as functional illnesses. Many diseases can cause cough, and several studies have shown asthma among the most common etiologies associated with chronic cough in adult nonsmokers, as well as children. Psychogenic cough and its relationship to asthma and other asthma-like illnesses is complex since distinct maladies with similar features may coexist individually or in combination in any given patient. While chronic cough may occur as a sole presenting manifestation of bronchial asthma in all age groups, recent findings suggest that most children with persistent cough without other respiratory symptoms do not have asthma. Since several organic, as well as functional diseases, may present with persistent cough as their sole manifestation in either adults or children, cough should not be used as a single or major determinant to diagnose and treat asthma, especially when empirically focused therapy trials fail. Given the range of illnesses causing cough, no single management guideline can be expected to be universally effective.     

“Recumbent” gait: Relationship to the phenotype of “astasia‐abasia”?

Psychogenic gait disorders can present in many different ways. Among patients with a pure psychogenic gait disorder, buckling of the knee is the most common feature, followed by astasia-abasia. Here, we describe one such patient with a very unusual gait disturbance that might be regarded as a variant of astasia-abasia. The patient characteristics are described and discussed in a historical context.     

以头晕为主诉的无症状性脑梗死患者焦虑状态的临床分析

目的:探讨以头晕为主诉的无症状性脑梗死(ACI)患者的情绪状态及临床体验并观察抗焦虑/抑郁治疗的疗效.方法:对98例ACI患者采用汉密尔顿焦虑抑郁量表进行筛查,并根据ICD-10的诊断标准做出诊断后,给予抗焦虑/抑郁药物治疗和支持性心理治疗,以治疗前后的汉密尔顿焦虑量表(HAMA)的减分率和临床症状缓解程度来评定疗效.结果:处于焦虑状态的ACI患者,医检证实均有脑血管系统的轻微病损,头晕史0.5～7年,有心悸、气短、眩晕发作、失眠等自诉躯体症状,67.55%伴有高血压;经帕罗西汀和支持性心理治疗,100%显效,临床症状缓解.结论:以头晕为主诉的ACI患者,若经改善脑血流循环治疗无效者,则应实施抗焦虑/抑郁药物治疗和支持性心理治疗,可望获得良好疗效.     

The MMPI and chronic pain: The diagnosis of psychogenic pain

This study investigates the capacity of the MMPI to discriminate among groups of patients with different types of pain. When multivariate analysis of variance is used, the standard set of MMPI scales discriminates between acute pain and chronic pain but not between chronic pain of two different etiologies (surgicaliatrogenic vs. unknown). The three scales that discriminate acute from chronic pain patients are those in the neurotic triad, Hs, D, and Hy. The possibility that the unknown pain etiology group could be broken down into psychogenic pain and undetected somatogenic pathology subgroups was explored using cluster analysis. This procedure did not yield any group of patients who could be identified as having chronic pain of psychogenic origin. These results suggest that the MMPI is not a reliable tool for the differential diagnosis of chronic pain. It appears, however, that patterns of findings are partly contingent on population characteristics. Researchers should be cautious about generalizing to populations other than those from which samples are drawn.This research was supported in part by a grant from Roche Laboratories, Nutley, New Jersey, and the Anesthesiology Research Center, Grant No. GM1599-1-06, University of Washington, Seattle, Washington.     

"Fatigue on rest" and associated symptoms (headache, vertigo, blurred vision, nausea, tension and irritability) due to locally asymptomatic, unerupted, impacted teeth.

"Fatigue on Rest", headache, vertigo and the feeling of loss of balance, blurred vision, nausea, tension and irritability, were found to be prevalent amongst patients who had locally asymptomatic, unerupted impacted teeth. A comparative pressure sign was developed, which, when positive, confirmed the relationship between the impacted teeth and the medical symptoms. Removal of the impactions resulted in the alleviation of the symptoms. Stress and psychogenic factors are considered as trigger mechanisms, rather than as basic causes of the symptoms.
