Karyotype Abnormality

BackgroundA few recent linkage studies have shown a possible locus for bipolar disorder on chromosome 18. Cytogenetic studies may assist in the further localisation of susceptibility loci on this chromosome.MethodA search was made for abnormalities of chromosome 18 in two separate large cytogenetic databases. In Denmark detection of mental illness in subjects with chromosome abnormalities was done by cross-linking the two separate register of psychiatric and chromosome disorders. In Scotland the Cytogenetic Registry of the MRC Human Genetics Unit undertakes long-term clinical follow-up of all cases with chromosome abnormalities.ResultsCross-linking the two Danish register's revealed a family with the rare karyotype abnormality inv(18) (p11.3;q21.1) with one inversion carrier who also suffered from bipolar disorder. In this family there were two other cases of bipolar disorder, but the karyotype of these cases could not be established. One family in Scotland showed a case of schizophrenia in a carrier of inv(18) with the same breakpoints as the Danish family.ConclusionsWe suggest further studies of the 18p11.3 and 18q21.1 regions in order to identify genes involved in bipolar affective disorder and schizophrenia.

This chapter deals with the other major psychotic illness, bipolar affective disorder. Bipolar disorder poses a difficult question for outreach workers, as patients are often well recovered between episodes—so should persisting outreach be provided? We report very good results in severe bipolar disorder where continuity of care has paid off. The chapter also deals with theories of causation and classification. The section on treatment identifies the importance of early admission in hypomania, the use of mood stabilizers, and the value of identifying and agreeing on relapse signatures. It also confirms the value of working hard to strengthen the therapeutic relationship and of psychosocial interventions such as psycho-education. Long-term work with these patients brings home just how persistent and disabling the depressive phases can be.

Physiological Differences

Background. Though previous studies have clearly shown that lithium affords prophylaxis in bipolar affective disorder, these studies have not demonstrated the persistence of this prophylactic effect beyond the first year of recovery.Methods. One hundred and eighty-one patients with bipolar affective disorder recovered during 5 years of semi-annual follow-up. After 8 weeks of recovery, 139 were taking lithium prophylaxis and 42 were not. Analyses used drug status (lithium v. no-lithium) as a censoring variable to compare these two groups by interval-specific probabilities of recurrence.Results. Recurrence was initially less likely in the lithium group but interval-specific probabilities of recurrence did not consistently favour either group after the first 32 weeks of recovery.Conclusions. Biases in treatment decisions may have both reduced the size and altered the specificity of the lithium effects seen here. Nevertheless, the apparent transience of lithium prophylactic effects is unexplained and may reflect important, physiological differences between relapse and recurrence. This possibility invites a controlled lithium discontinuation study, with gradual taper, of patients who have had at least 8 months of sustained euthymia.

Great Excess

Goodwin (2000) famously argued that bipolar disorder was the Cinderella of psychiatry. It certainly should not be: there is no doubt of the anguish caused by the condition, in particular the excess of natural mortality and the great excess of death by suicide (Ösby et al. 2001). In this issue, Mitchell et al. (2004) report that 26% of their cases of bipolar disorder had attempted suicide at some point. This reflects the sheer persistence of personal suffering: Judd and colleagues (2002, 2003) demonstrated in a long and detailed follow-up that patients with bipolar disorder were symptomatic at least half the time. The Australian National Survey of Psychotic Disorders found levels of disability in affective psychosis equal to those of schizophrenia (Jablensky et al. 2000), and bipolar cases are more likely to score highly on measures of disability than unipolar cases (Mitchell et al. 2004). People with bipolar disorder are more likely to be single, widowed or divorced than both the general populace and those with unipolar depression (Mitchell et al. 2004).

Rule Out

Neurocysticercosis is the most common neuro-parasitosis caused by the larval stage of Taenia solium. The most common manifestations include seizures and hydrocephalus. Psychiatric abnormalities are relatively rare but depressive symptoms are frequent in patients with neurocysticercosis. However, mania as a presentation is relatively rare. Pregnancy and the postpartum period are relatively vulnerable times and they can lead to reactivation of existing neurocysterci lesions. We are discussing the case of a 23-year-old female patient with neurocysticercosis leading to the reactivation of lesions in the peripartum and postpartum period leading to bipolar affective disorder. Improvement in the patient was seen with a combination of antipsychotics, antihelmintics, antiepileptics and steroids, along with improved radiological signs of neurocysterci lesions. Although neurocysticercosis is a common illness, its prevalence presenting as a manic episode is merely 2.6% and, hence, missed easily. Therefore, it is important to rule out organic aetiology in patients even with a classic presentation of bipolar affective disorder and those having any other neurological symptoms and signs.

Background Cross-sectional studies have found impaired cognitive functioning in patients with bipolar disorder, but long-term longitudinal studies are scarce. Aims The aims of this study were to examine the 6-year longitudinal course of cognitive functioning in patients with bipolar disorder and healthy controls. Subsets of patients were examined to investigate possible differences in cognitive trajectories. Method Patients with bipolar I disorder (n = 44) or bipolar II disorder (n = 28) and healthy controls (n = 59) were tested with a comprehensive cognitive test battery at baseline and retested after 6 years. We conducted repeated measures ANCOVAs with group as a between-subject factor and tested the significance of group and time interaction. Results By and large, the change in cognitive functioning between baseline and follow-up did not differ significantly between participants with bipolar disorder and healthy controls. Comparing subsets of patients, for example those with bipolar I and II disorder and those with and without manic episodes during follow-up, did not reveal subgroups more vulnerable to cognitive decline. Conclusions Cognitive performance remained stable in patients with bipolar disorder over a 6-year period and evolved similarly to healthy controls. These findings argue against the notion of a general progressive decline in cognitive functioning in bipolar disorder.

ABSTRACT Purpose To determine the long-term alterations of corneal thickness, along with topographic outcomes, after corneal collagen cross-linking treatment (CXL) for keratoconus. Materials and methods In this retrospective case series, 46 patients (52 eyes), 32 males and 14 females, with progressive keratoconus were included. All eyes underwent CXL in accordance with the standard protocol (Dresden) for the treatment of their ectatic corneal disorder between January 2006 and June 2007. Pachymetric and topographic outcomes were evaluated preoperatively and at 1, 3, 6, 12, 24 and 36 months postoperatively. Results Mean follow-up was 28.08 ± 8.39 months (range, from 12 to 36 months). A statistically significant decline in corneal pachymetric values (at the thinnest location) when compared with preoperative values (467.65 ± 41.08 µm) was demonstrated at 1 (437.63 ± 50.57 µm), 3 (439.08 ± 52.27 µm), 6 (449.37 ± 52.73 µm), 12 (449.63 ± 83.53 µm) and 24 (459.97 ± 47.32 µm) months after CXL (p < 0.05, for all mentioned time intervals). Return to preoperative pachymetric values (469.52 ± 40.52 µm) was revealed 36 months post-CXL (p > 0.05). With respect to topographic (flat and steep keratometric values, keratoconus index), no statistically significant differences between preoperative and all postoperative intervals were found (p > 0.05, for all values for all time intervals). Conclusion Corneal pachymetric values reduce significantly up to 24 months after CXL treatment, while a return to preoperative values was revealed 36 months after the procedure. No significant changes’ concerning topographic outcomes was demonstrated after CXL, indicating stability of these parameters.

ABSTRACT Purpose To report refractive, topographic and safety outcomes of corneal cross-linking (CXL) in patients younger than 18 years of age with progressive keratoconus. Materials and methods In this retrospective study, we enrolled 31 eyes of 21 children aged 11 to 17 years that underwent corneal riboflavin-ultraviolet A induced CXL due to progressive keratoconus at three different ophthalmology departments in Israel. They were followed for 3 to 48 months (average 23 ± 13.6 months). Evaluated parameters were uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA), manifest refraction, pachymetry, slit- lamp examination and corneal topography at baseline and at 1,3,6,12,24 and 48 months. Results We found a nonsignificant improvement in UCVA and BSCVA with a small reduction of manifest cylinder and no significant change in spherical equivalent or K-values. Following CXL, stability of UCVA and BSCVA at the last follow-up examination was found in 71 and 77% of treated eyes, respectively. No permanent adverse events have been recorded throughout the study period. Conclusion In our series, CXL was a safe procedure in the pediatric population. Stabilization of progressive keratoconus was achieved in visual acuity, refractive and topography parameters with no improvement in corneal indices in contrary to adult CXL treatment.

Hypnotic Agent

Zolpidem is a short-acting non-benzodiazepine hypnotic agent, commonly recommended for short-term treatment of insomnia. Zolpidem has less dependence potential than benzodiazepines. Patients with mental illnesses often have disturbed sleep, for which zolpidem is often prescribed. Long-term use and self-medication (in more than recommended doses) are more likely to cause dependence. We report here a case of bipolar affective disorder with epilepsy, who developed dependence to zolpidem and had severe withdrawal symptoms. The management issues are also discussed with review of the literature.

Abstract Background Bipolar disorder is one of the world’s 10 most disabling conditions, taking away years of healthy functioning from individuals, all bipolar disorders are chronically recurring illnesses associated with substantial morbidity and mortality. Impulsivity considered an integral part of bipolar disorder. Operationalized as a predisposition to action without reflection or regard for consequences. Potential consequences of this increased impulsivity include substance abuse, suicidal attempts, and other serious behavioral problems. Aim of the Study The aim of the current study was to measure impulsivity in both BD euthymic patients and in healthy first-degree relatives of BD patients. And to assess the functional implications of impulsiveness, on psychosocial functioning and in bipolar disorder patients, their first-degree relatives. Patients and Methods A convenient sample of 50 patients; diagnosed with bipolar affective disorder according to DSM-IV diagnostic criteria were selected from the general adult psychiatry clinics and a convenient sample of 50 healthy first degree relatives of BD patients. Results We concluded by the end of this study that both cases and relatives have high overall impulsivity, and cases have higher impulsivity in comparison to relatives. Conclusion We suggest that impulsivity may be a potentially valuable candidate endophenotype for bipolar disorder.
