Quetiapine is a medication approved for the treatment of psychotic disorders in adults. At this time it is not approved for the treatment of children or adolescents. It is an atypical antipsychotic agent that is efficacious in treating both the positive and negative symptoms of schizophrenia. There is currently little information available concerning the safety of quetiapine in overdose, and there are no previous case reports of quetiapine overdose in the pediatric population. We present the case of a 15-year-old girl who ingested 1250 mg of quetiapine (21.6 mg/kg) in a suicide attempt. She developed multiple symptoms including tachycardia, agitation, hypotension, and unconsciousness. We compare her symptoms to previous adult cases of quetiapine overdose and review overdose treatment recommendations. We also examine clinical situations that may lead to a more severe clinical course.

A 63-year-old African-American woman was admitted to the hospital with urosepsis and altered mental status. She had a history of schizophrenia and was treated with olanzapine 5 mg/day and lithium carbonate 300 mg 3 times/day. During her hospital stay, her sodium level and serum osmolality increased and her urine osmolality decreased, whereas her lithium levels remained within normal limits. Based on these findings, the patient was diagnosed with diabetes insipidus secondary to lithium therapy and was treated successfully with amiloride. Clinicians have been aware of lithium toxicity for many years and traditionally have administered thiazide diuretics for lithium-induced polyuria and nephrogenic diabetes insipidus. Recently, amiloride, a potassium-sparing diuretic, has been reported as a successful treatment for nephrogenic diabetes insipidus.

The author describes how work with inpatients with chronic schizophrenia has contributed to a better understanding of antisocial behavior. She has used the concept of regression, along biological and psychological lines, to hypothesize fantasies of primitive object relationships which drive the behavior. Engaging patients in thoughtful reflection, she has introduced a third perspective on the potential state of mind of the important people in their lives; the possibility of a concerned object, rather than that of a vengeful or rejecting object. Finding that even those with resistant schizophrenia respond with change in behavior, she found that she could more easily employ the same psychoanalytic concepts in engaging those who present with more acute problems of violent and suicidal behavior.

Because of the importance of maintaining current knowledge of technological advances involving genetics, neuroscience, and their impact on psychopharmacology, we have created a new column for advanced practice psychiatric nurses. This new column offers a question-and-answer forum that can help nurses maintain their knowledge of advances in prescribing and psychopharmacology, and implications for safe psychiatric care. Deborah Antai-Otong has a wealth of knowledge and expertise with prescriptive authority and as a psychotherapist. She currently manages the care of patients with various psychiatric disorders including mood disorders, schizophrenia, dual diagnosis, and anxiety disorders. She is the author of numerous refereed journal articles and book chapters that focus on psychopharmacology and is a guest lecturer at a local university on this topic. She is also the author of several books, including Psychiatric Nursing: Biological and Behavioral Concepts (Clifton Park, NY: Delmar & Thompson Learning, 2003) and Psychiatric Emergencies (Eau Claire, WI: PESI, 2001).

Although factitious disorder has been known for a long time, its diagnosis and treatment continue to be a problem. It is an uncommon condition associated with considerable morbidity and health care expenditure. We present a case of factitious disorder with hallucinations. A 37 year-old single woman has had auditory and olfactory hallucinations for six years. She had been diagnosed with schizophrenia, hospitalized for a short term, taking classical antipsychotic drugs for years. She has been performing her job as a teacher and living with her family. A suitable dose of atypical antipsychotic drugs was administered at a convenient time for her illness (Psychotic Disorder NOS) in psychiatric outpatient clinic of Kocaeli University. She was admitted to inpatient clinic twice in order to allow a clear diagnosis to be made. Psychotic disorder and temporal lobe epilepsy were ruled out. Borderline and histrionic personality traits were determined. Her complaints were unchanged over the course of treatment taking three years. She later started to come into the emergency department with anxiety symptoms, conversion like fits and suicide attempts; hospitalized for these complaints in another hospital. She was diagnosed with factitious disorder because of her unchanged complaints, her adding new complaints to the old ones, her complaints unrelated to psychosocial stressors, her ambitions to come to hospital, her increasing hospital dependence and having no prominent secondary gain. This case emphasizes the need for the careful observation of patients to prevent unnecessary investigations at the diagnosis and treatment stage and to establish a specific management strategy for the patients.

Perospirone is a novel serotonin-2 and dopamine-2 receptor antagonist (SDA) developed in Japan. Premarketing trials suggested that this agent was effective in reducing positive and negative symptoms of schizophrenia and had a favorable side-effect profile. However, these trials included only a few elderly patients, so the usefulness of perospirone in this population remains unknown. In this report we describe the treatment of 2 elderly patients with schizophrenia for whom perospirone therapy was efficacious. Case 1 was a patient with acute exacerbation of schizophrenic symptoms after discontinuance of medication. He was treated with 12 mg of perospirone daily and his symptoms reduced markedly from the 4th day of perospirone therapy. Efficacy was assessed by the positive and negative symptom scale (PANSS); all subscales of PANSS (positive symptom, negative symptom, and general psychopathology) reduced and the total score reduced from 78 to 38 by the end of the 6th week of treatment. No side effects such as extrapyramidal symptoms were noted. Thus, perospirone may be a useful antipsychotic for elderly patients with acute schizophrenia. Case 2 was a patient who had severe negative symptoms and extrapyramidal symptoms such as tardive dyskinesia, tardive dystonia, and sialorrhea. She had been hospitalized for more than 7 years. In this patient 12 mg of perospirone was administered daily after 3 mg of risperidone had been tapered off. The negative symptom subscale and general psychopathology subscale in PANSS were gradually reduced after perospirone therapy was started. Extrapyramidal symptoms were assessed by the drug-induced extrapyramidal symptoms scale (DIEPSS), which consists of eight individual parameters and one global assessment, and each parameter is graded on a 5-point (0 = none to 4 = severe) scale. Sialorrhea, muscle rigidity, tremor, dystonia and overall sererity were improved more than 2 points by the end of the 6th week. The clinical course of this patient suggests that the clinical characteristics of perospirone and risperidone may be different, even though these agents are categorized into the same class of antipsychotics, SDA. Because this is a case report, evaluations are limited the clinical properties of perospirone. Further examination is necessary to evaluate the efficacy and safety of perospirone for elderly patients with schizophrenia, who are more vulnerable to the side effect of antipsychotics than the younger population.

In schizophrenic patients, cognitive and behavioral deficits are often associated with frontal lobe dysfunction. By functional neuroimaging studies, abnormalities of the frontal lobe (especially the prefrontal lobe) have been detected in schizophrenic patients. As for morphological changes on neuroimaging, lateral lobe atrophy and enlargement of the lateral ventricles or third ventricle are often reported, but there is no consensus as to whether frontal lobe atrophy is seen more frequently in schizophrenic patients compared with normal controls. The reasons for this disagreement include variations in the precision of measurement on MRI, differences in the methods of MRI among studies, and biases in the subjects being evaluated. Here we present a patient with schizophrenia and frontal lobe atrophy, which was clearly recognized on MRI and showed no progress in the 2 years following its detection. The patient was a 26-year-old woman with a 4.5-year history of schizophrenia when she was referred to us for the treatment of persistent auditory hallucinations and delusions. She showed no neurological findings apart from her psychiatric symptoms. Head MRI showed mild atrophy of the frontal lobe, and the extent of atrophy did not change over the following two years. On resting SPECT 99mTc-HMPAO, hypoperfusion of the bilateral frontal regions was demonstrated. There were no significant findings in the temporal lobe on either MRI or SPECT. She achieved low scores in neuropsychological tests of intelligence, memory, and frontal lobe-associated functions, and showed almost the same degrees of impairment in all of the tests in 2 years of follow-up. The possibility of degenerative diseases, such as young-onset frontotemporal dementia, was ruled out. She had a low intelligence quotient in the WAIS-R and her answers showed the specific pattern which is commonly seen in schizophrenic patients. There is a possibility that hypoperfusion on resting SPECT reflected not only frontal lobe atrophy, but also frontal lobe dysfunction in this patient. Frontal lobe dysfunction in schizophrenics is generally considered to be a secondary effect of meso-limbic system pathology. In this patient, however, the dysfunction seemed to arise from an intrinsic disorder of the frontal lobe, because frontal lobe abnormalities were conspicuous, whereas the temporal lobe was almost normal on both MRI and SPECT.

Ten years ago a 45-year-old female presented with bilateral maculopathy with visual acuity of 6/18 on the right and 6/24 on the left. She had been on fluphenazine for the past 10 years for schizophrenia. Investigation including fluorescein angiogram, colour vision assessment and electrophysiological testing confirmed the nature of the retinal damages. Her maculopathy deteriorated further despite discontinuation of the medication. A previous publication has reported maculopathy with fluphenazine in association with the welding arc injury, but that particular patient had not been exposed to welding flash or other extreme photochemical sources. We believe this is the first reported incidence that fluphenazine has directly caused a maculopathy secondary to its accumulation at the retinal pigment epithelium and its toxic effect.

A 61-year-old woman with schizophrenia that had been treated in a psychiatric hospital was admitted to our hospital because of subileus and back pain. Though subileus was improved, she had a sudden attack of fever 7 days later and developed right pleural effusion, a cold abscess in the anterior chest wall and swelling of a thumb-sized right cervical lymph node which broke through the skin. We made a diagnosis of cervical and mediastinal lymph nodes tuberculosis, tuberculous pleurisy, spinal caries and cold abscess in the anterior chest wall due to the biopsy findings of the specimen taken from the cervical lymph node, examination of pleural effusion, chest CT, bacteriological examination of the cold abscess and spinal MRI. We started chemotherapy with the antituberculous drugs (HRSZ) and symptoms except back pain improved. She complained of paresis of the both lower extremities, which completely paralyzed 8 months later in spite of continued chemotherapy. Thereafter her paralysis was gradually improved and she was able to walk by herself after 12 months chemotherapy.

In this article, we discuss the ethical dilemma health care providers faced when Rebecca, a pregnant schizophrenic patient who lacked decision-making capacity, inconsistently requested elective pregnancy termination. When a patient's decision-making capacity is severely impaired, how does the physician balance obligations to protect the patient from harm (beneficence) while also respecting her reproductive preferences and decisions (respect for autonomy)? Rebecca suffers from polysubstance abuse and paranoid schizophrenia characterized by disorganized thought and speech, auditory hallucinations, and delusional ideas. She arrived 14+ weeks pregnant and unaccompanied at an obstetric clinic requesting an abortion. This is her second and final request. On all prior and subsequent occasions, she was either ambivalent or said she wanted to continue the pregnancy. After the consulting psychiatrist determined that she lacked decision-making capacity, steps were taken to address ethical and clinical issues. The steps included treating her schizophrenia to see if she could regain decision-making capacity; identifying a surrogate and using a shared decision-making model; and devising strategies to protect Rebecca and her fetus without resorting to excessive paternalism. Rebecca continued her pregnancy. Due to poor adherence to medical regimen and inadequate social support, Rebecca's schizophrenia was poorly controlled and she continued to use drugs during the pregnancy. She delivered a term baby who was soon removed from her custody. Despite some people's desire to protect Rebecca by complying with her request for abortion, we conclude that to do so would be ethically unjustified. To treat a decisionally impaired patient's requests for abortion as autonomous is disrespectful of the vulnerable patient because such paternalism fails to respect the patient's liberty and the surrogate's authority.
