RESUMEN
Malignant struma ovarii (MSO) is a rare ovarian teratoma composed primarily of thyroid tissue. Common sites of metastasis include peritoneum, bone, liver, lung, gastrointestinal tract and omentum. We present a woman in her 50s with a history of remote oophorectomy presenting with hypopituitarism and a 2.7 cm sellar mass. Trans-sphenoidal surgery for presumed pituitary macroadenoma achieved near total resection and resultant pathology surprisingly showed ectopic thyroid tissue. The patient acquired her ovarian pathology report from Southeast Asia which showed struma ovarii of the left ovary. The pituitary mass was thus determined to be a metastatic lesion from MSO. She underwent total thyroidectomy and radioactive iodine ablation therapy with good initial response and no regrowth of the tissue or emergence of distant metastases after 5 years of annual follow-up. To our knowledge, this is the first reported case of MSO to the pituitary.

OBJECTIVE: Late-life depression (LLD) is known to negatively impact cognition even after remission of mood symptoms. Electroconvulsive therapy (ECT) and newer nonconvulsive electrical and magnetic brain stimulation interventions have been shown to have cognitive effects in patients with neuropsychiatric disorders. METHODS: This review systematically assessed the effects of ECT on cognition in LLD. EMBASE, Ovid Medline, and PsycINFO were systematically searched through June 2015. The search was limited to publications from peer-reviewed journals in the English language. RESULTS: A total of 5,154 publications was identified; 318 were reviewed in full text, of which 39 publications related to ECT were included. We focused this review only on ECT because evidence on newer interventions was deemed insufficient for a systematic review. This literature suggests increased rates of interictal and postictal cognitive decline with ECT but no long-term (i.e., 6 months or longer) deleterious effects on cognition. Instead, long-term cognitive outcomes with ECT have been reported as either not changed or improved. This literature favors nondominant unilateral ECT over bilateral ECT for cognition. CONCLUSION: Published literature on brain stimulation interventions in LLD is mainly limited to ECT. This literature suggests that deleterious effects of ECT in LLD are limited and transient, with better cognitive outcomes with unilateral ECT. There is not enough evidence to fully characterize long-term deleterious effects of ECT or effects of newer brain stimulation techniques on cognition in LLD.

OBJECTIVE: Life expectancy in individuals with schizophrenia continues to increase. It is not clear whether cognitive deficits associated with schizophrenia remain as strong predictors of function in older and younger individuals. Thus, we assessed the relationship between cognition and functional competence in individuals with schizophrenia across 7 decades of life. METHODS: We analyzed data obtained in 232 community-dwelling participants with schizophrenia (age range: 19-79 years). Cognition was assessed using the Measurement and Treatment Research to Improve Cognition in Schizophrenia Consensus Cognitive Battery. Functional competence was assessed using the UCSD Performance-based Skills Assessment, which includes measures of Comprehension and Planning of Recreational Activities Skills, Financial Skills, Communication Skills, Transportation Skills, and Household Management Skills. To assess the effects of Global Cognition on functional competence, we performed hierarchical multivariate linear or logistic regression analyses controlling for age, education, gender, and negative symptoms. RESULTS: Participants' mean age was 49.1 (SD = 13.2, range = 19-79 years), 161 (69%) were male, and 55 (24%) were aged ≥60. Global Cognition was a predictor of Comprehension and Planning Skills (Exp(ß) = 1.048), Financial Skills (Exp(ß) = 1.104), Communication Skills (ΔR (2) = .31) and Transportation Skills (Exp(ß) = 1.066), but not Household Management Skills after adjusting for age, education, gender, and negative symptoms of schizophrenia. CONCLUSION: Cognition remains a strong predictor of functional competence across the lifespan. These findings suggest that treating cognitive impairment associated with schizophrenia could improve individuals' function independent of their age.

The objective of this study was to examine the prevalence and patterns of antipsychotic use in children and adolescents at the time of admission and discharge from a tertiary care inpatient psychiatric facility. This retrospective analysis included all patients 18 years and younger, who were admitted and discharged from a child and adolescent tertiary care inpatient psychiatric facility between May 1, 2008 and December 31, 2009. Data for medications at admission were obtained using a province-wide network that links all pharmacies in British Columbia, Canada to a central set of data systems, whereas data for medications at discharge were obtained using the Department of Pharmacy's (British Columbia Children's Hospital, Vancouver, British Columbia, Canada) inpatient computer database. Apart from antipsychotics, overall drug use included antidepressants, mood stabilizers, benzodiazepines, anticholinergics, stimulants, and sleep medications. Referral and discharge diagnoses were also examined. During the study period, 335 patients were admitted and discharged from the tertiary care inpatient psychiatric facility. Significantly, more patients were prescribed with an antipsychotic at the time of discharge from hospital compared with that of the time when they were admitted to hospital (51.6% vs 30.7%; P < 0.0001). Antidepressants were most often coprescribed with an antipsychotic at admission and discharge (32.0% vs 42.2%, respectively) followed by attention-deficit/hyperactivity disorder medications (22.3% vs 24.9% at admission and discharge, respectively) and anticonvulsants (19.4% vs 19.1% at admission and discharge, respectively). Whether the significant increase in antipsychotic use seen from the time of admission to discharge is solely attributed to clinical worsening or other variables requires further investigation.

OBJECTIVE: To identify chromosomal regions harboring quantitative trait loci for waist circumference (WC) and body mass index (BMI). DESIGN AND METHODS: A genome-wide linkage scan and regional association study WC and BMI among 633 Chinese families was conducted. RESULTS: A significant linkage signal for WC was observed at 22q13.31-22q13.33 in the overall analysis (LOD = 3.13). Follow-up association study of 22q13.31-13.33 revealed an association between the TBC1D22A gene marker rs16996195 and WC (false discovery rate [FDR]-Q < 0.05). In gender-stratified analysis, suggestive linkage signals were attained for WC at 2p24.3-2q12.2 and 22q13.33 among females (LOD = 2.54 and 2.15, respectively). Among males, 6q12-6q13 was suggestively linked to BMI (LOD = 2.03). Single marker association analyses at these regions identified male-specific relationships of six single nucleotide polymorphisms (SNPs) at 2p24.3-2q12.2 (rs100955, rs13020676, rs13014034, rs12990515, rs17024325, and rs2192712) and five SNPs at 6q12-6q13 (rs7747318, rs7767301, rs12197115, rs12203049, and rs9454847) with the obesity-related phenotypes (all FDR-Q < 0.05). At chromosome 6q12-6q13, markers rs7755450 and rs11758293 predicted BMI in females (both FDR-Q < 0.05). CONCLUSIONS: Genomic regions on chromosomes 2, 6, and 22 which may harbor important obesity-susceptibility loci were described. Follow-up study of these regions revealed several novel variants associated with obesity related traits. Future work to confirm these promising findings is warranted.

Late-life mental illness is a growing concern. Current medications have limited efficacy and are associated with safety concerns. A variety of brain stimulation approaches offers alternative treatments. We performed a systematic literature search on the efficacy and safety of brain stimulation in late-life mental illnesses, excluding unipolar nonpsychotic depression. Studies on deep brain stimulation, electroconvulsive therapy (ECT), repetitive transcranial magnetic stimulation (rTMS), and vagal nerve stimulation that enrolled exclusively older adults (≥65 years) or analyzed older adults as a separate group were included. The search identified 1,181 publications, of which 43 met the above inclusion criteria: 24 were related to the treatment of non-unipolar depression (ECT: 21; rTMS: 2; ECT and rTMS: 1), 14 related to dementia (ECT: 7[2 of these studies were also related to depression]; vagal nerve stimulation: 2; rTMS: 4; deep brain stimulation: 1), and 7 to schizophrenia (ECT: 7). These studies reported a high degree of variability in efficacy and safety with promising results in general, particularly in the treatment of dementia and schizophrenia. Most publications were limited by small sample sizes, lack of control conditions, and lack of randomization. Large studies with a randomized controlled design or other designs such as crossover or off-on-off-on are needed. In contrast to the empiric and nonspecific use of ECT, future studies using modalities other than ECT could focus on novel biologically based interventions that target specific circuitry. These interventions could also be combined with other non-brain stimulation treatments for possible synergistic effects.

Impaired insight into illness is a common but poorly understood phenomenon in schizophrenia. Several studies in midlife adults with schizophrenia have reported an association between impaired insight and illness severity, executive dysfunction, premorbid intellectual function, and to a lesser degree attention. Aging is associated with a decline in attention and executive function. Thus, the relationship between cognition and insight is expected to differ between younger and older adults with schizophrenia. This study assessed this relationship among 50 patients with schizophrenia 60 years and older. Insight was explained by illness severity (16.2% of the variance) and premorbid intellectual function (23.9% of the variance), but not by attention or executive function. Our findings suggest that the predictors of insight in schizophrenia differ early and later in life. In particular, insight's association with attention and executive function observed in younger patients is attenuated by age-related changes in cognition. In contrast, premorbid intellectual function continues to be a strong predictor of insight in late life, which highlights the need to better understand and enhance cognitive function early in the course of schizophrenia.
