Board certification anxiety.

The authors discuss how stress influences the candidate's capacity to effectively prepare for and fully demonstrate his or her abilities in the oral examination in psychiatry given by the American Board of Psychiatry and Neurology. They highlight subtle misconceptions about examiner priorities, attitudes, and evaluation methods and note common errors that reflect both anxiety and these misconceptions. They offer some advice and information to aid the candidate in coping with these examination difficulties.

Neuropsychological and structural brain lesions in multiple sclerosis: a regional analysis.

Quantified lesion scores derived from MRI correlate significantly with neuropsychological testing in patients with multiple sclerosis (MS). Variables used to reflect disease severity include total lesion area (TLA), ventricular-brain ratio, and size of the corpus callosum. We used these general measures of cerebral lesion involvement as well as specific ratings of lesion involvement by frontal, temporal, and parieto-occipital regions to quantify the topographic distribution of lesions and consequent effects upon cognitive function. Lesions were heavily distributed in the parieto-occipital regions bilaterally. Neuropsychological tests were highly related to all generalized measures of cerebral involvement, with TLA being the best predictor of neuropsychological deficit. Mean TLA for the cognitively impaired group was 28.30 cm2 versus 7.41 cm2 for the cognitively intact group (p less than 0.0001). Multiple regression analyses revealed that left frontal lobe involvement best predicted impaired abstract problem solving, memory, and word fluency. Left parieto-occipital lesion involvement best predicted deficits in verbal learning and complex visual-integrative skills. Analysis of regional cerebral lesion load may assist in understanding the particular pattern and course of cognitive deficits in MS.

Postcardiotomy delirium: a critical review.

The literature concerning postcardiotomy delirium contains confusing definitions and contradictory results. In a critical review of the subject, we conclude that cardiac status, the severity of physical illness, the complexity of the surgical procedure, and preoperative organic brain disease are the determining factors in postcardiotomy delirium. Preoperative anxiety, denial, and depression also have some correlation. Age, sex, time on bypass, and preoperative psychological profile seem to have no influence on outcome. No psychological etiology for delirium has been proven consistently. The therapeutic influence of preoperative interviews in preventing postoperative psychiatric complications remains equivocal as do theories implicating sensory deprivation in the intensive care unit. Long-term follow-up studies suggest that psychological problems impair functional recovery from heart surgery. The suggested treatment of patients with delirium includes chemotherapy, psychotherapy, and environmental support. Finally we suggest that investigation of biochemical abnormalities in delirium may prove to be a model for clarifying the role of neurotransmitters in functional psychiatric illnesses.

Severe ocular self-injury.

To further delineate the clinical characteristics of patients who deliberately, severely mutilate their eyes, we reviewed the medical records of a specialty eye hospital and found nine cases of intentional, severe, self-inflicted eye injuries. We identified two groups of patients. Most were young psychotic individuals with severe psychopathology often involving sexual and religious delusions, command hallucinations, and the propensity to act on delusions. The second group was comprised of patients with organic disabilities, either dementia or severe mental retardation, where a lack of impulse control and preexisting eye irritation or surgical operation may have contributed to the act. One patient was a recidivist. Two-thirds of the patients were confined at the time of the act. That self-mutilation may occur frequently in confined patients calls for active vigilance from caretakers; that it may recur calls for caution by the psychiatrist.

Use of high dose benzodiazepines in alcohol and sedative withdrawal delirium.

The authors describe two patients who required massive doses of benzodiazepines to treat complicated alcohol and sedative withdrawal delirium. Some of the factors that contribute to difficulties in management are discussed. Finally, we describe the advantages and disadvantages of high dose pharmacologic management and controversies regarding psychopharmacologic management of such complex patients.

Dietary vitamin B12 deficiency in a patient with multiple sclerosis.

The authors present a case of dietary vitamin B12 deficiency in a patient with multiple sclerosis. A simple schemata for evaluating patients for vitamin B12 deficiency is included as a clinical aid for physicians.

Treating the patient who is disfigured by head and neck cancer.

A 46-year-old man with laryngeal carcinoma was admitted to the medical service for lethargy. The medical team requested a psychiatric consultation to assist with the patient's depression, substance abuse, and noncompliance. The case is presented and discussed with reference to the issues of depression, disfigurement, dysfunction, and substance abuse in the patient with head and neck cancer.

Oedipism in a patient with frontal lobe encephalomalacia.

There is a growing recognition of the role of the frontal lobes in the aetiology of severe behavioural aberrations. The authors describe a case of Oedipism in a patient who had MRI evidence of frontal lobe encephalomalacia. After discussing the function of the frontal lobes in modulating behaviour the authors suggest that the structural lesion seen on the MRI was in part responsible for the patient's self-destructive act. Treatment issues and the importance of recognizing underlying structural lesions in instances of extreme self-mutilation are discussed.

Impact of pregnancy during training on a psychiatric resident cohort.

The issues surrounding pregnancy during residency training include length of maternity leave, coverage during that leave, and relationships among resident colleagues. With more women entering medicine, the likelihood of a majority of residents in any postgraduate year being pregnant at one time has increased. This study presents an in-depth view of one such resident cohort. Conflicts occurred over the perception that pregnant residents received special treatment. The defenses mobilized by residents included projection and denial.

St. John's Wort.

OBJECTIVE: The objective of this article is to review the current knowledge of the pharmacology, sites of action, and therapeutic effectiveness of St. John's Wort. METHOD: The method used was a review of the available literature, using keywords to search the medline database. Bibliographies of the papers, thus obtained, were searched for further documents not referenced by medline. We reviewed papers from this collection. RESULTS: This review reveals that most of the available data on efficacy and safety of St. John's Wort involve its use in mild to moderate depression. Much, but not all of the prevailing opinion is positive. Nevertheless, the quality of therapeutic trials vary so greatly that definitive conclusions are not possible. Both the source and mode of St. John's Wort's therapeutic effect are unclear. We need further controlled studies of effectiveness, safety, and mode of action. In addition to its use in depression, there are reports suggesting possible therapeutic effects in other conditions such as certain malignancies and infections, but these are far too preliminary to permit any conclusions.

Hematologic side effects of psychotropics.

Psychiatrists are often unaware of the potential hematologic complications of the psychotropics they prescribe. Although this review is not a hematologic text reference, relevant hematologic syndromes are described so that the consultation-liaison psychiatrist will be familiar with the usual signs, symptoms, and treatments of these syndromes. This article reviews the hematologic side effects of the commonly prescribed psychotropics, including antipsychotics, antidepressants, benzodiazepines, lithium, mood stabilizers (including some of the anticonvulsants), and the acetylcholinesterase inhibitors. Clinical signs and symptoms that should alert the physician to obtain a complete blood count are described.

The sensitivity of the Mini-Mental State Exam in the white matter dementia of multiple sclerosis.

Fifty-six patients diagnosed with definite multiple sclerosis (MS) according to Poser criteria were administered the Mini-Mental State Examination (MMSE) and a comprehensive battery of neuropsychological tests. Extent of cerebral lesion involvement was determined by quantitative magnetic resonance imaging (MRI) ratings. The MMSE correlated with overall levels of physical disability, but did not correlate with total lesion area on MRI. Sensitivity of the MMSE to the subcortical dementia of MS was low (28%) when performance on the neuropsychological testing battery was used as the criterion. Impairment on tests of memory, speed of information processing, abstract reasoning, naming/verbal fluency, as well as visuoperceptual organization, were correlated highly with total lesion area on MRI. The low sensitivity of the MMSE to cognitive impairment in MS is discussed in terms of its item composition and the characteristic pattern of deficits found in MS.

Depression in Korean immigrants with hepatitis B and related liver diseases.

The authors evaluated 50 Korean immigrants who had chronic viral hepatitis or who were healthy carriers for the hepatitis B virus in terms of the relationships between their depression scores, psychosocial stressors, social support, and biological markers of dysfunction. All participants completed a questionnaire, describing their worries and concerns, and the shortform of the Beck Depression Inventory (BDI-sf). Hepatic transaminases, albumin levels, and prothrombin times were measured during routine clinic follow-up visits and were abstracted from the medical record. Values recorded within 3 months before and within 3 months after the psychiatric interview were correlated with BDI scores. BDI-sf total scores were significantly associated with transaminase elevations (P<0.001) both before and after BDI-sf administration. BDI scores were not associated with other measures of liver dysfunction or other medical causes of depression. Patients with higher BDI-sf total scores had more psychosocial stressors (P = 0.008) and lower Global Assessment of Functioning (GAF) scores (P = 0.000).
