Aim:The present study attempted to find out the relationship between positive and negative clinical symptoms and Wisconsin Card Sorting Test (WCST) performance in a group of schizophrenia patients.Methodology:Fifty schizophrenia patients were assessed using the Positive and Negative Syndrome Scale (PANSS) by a trained psychiatrist (TKA) and two groups, each of 25 positive symptom and 25 negative symptom schizophrenia patients were formed. On these fifty patients with schizophrenia and 15 normal control groups, WCST measures were applied by a clinical psychologist (SS) who remained blind to the PANSS score.Results:Schizophrenia diagnosis significantly affects WCST performances. One-way analysis of variance (ANOVA) revealed schizophrenia patients showed a significant impairment on all WCST indices compared with normal subjects except versus total number of correct responses. Post hoc comparison (Tukey HSD Test) between means revealed that negative schizophrenia patients showed significantly worse performance on most WCST performance parameters: percent errors, perseverative responses, percent perseverative responses, perseverative errors, percent perseverative errors, and conceptual level responses.Conclusions:Both positive and negative symptom schizophrenia patients have some distinct WCST measures deficits.

Patients who discontinued early from a 6-month treatment period with Paliperidone have some characteristic differences compared with completion patients. Many factors including frequent hospitalisations, female gender, high PANSS score (indicating more disease severity) and previous exposure to first generation of antipsychotic agent might lead patients to discontinue from treatment.

Catatonia is characterized by marked psychomotor disturbance and was first described by Karl Ludwig Kaulbaum in 1874.1 Later, it was evaluated as a subtype of schizophrenia. After the 1960s, it was revealed that other conditions can also cause catatonia.2 Gelenberg (1976) said there could be more than 40 cases that could cause catatonia and many new ones have emerged since then.3 Previous data suggest that catatonia is more common in mood disorders than in schizophrenia. The other causes of catatonia can be due to medical causes like endocrine disorders, infections, electrolyte imbalance, epilepsy, and traumatic brain injury. An excessive dosage of drugs or substances like cocaine, ecstasy, disulfiram, and levetiracetam can also result in catatonia.4,5

Everyone has the right to live in this world and also every individual has responsibility to use natural resources judiciously. This will give equal opportunity to all to use the resources for the benefit of whole mankind. All living creatures belong to mother earth and they all have their shine of resources available. All these resources like land, energy, mineral, food, water, forest etc. have to be distributed in an equitable way for sustainable lifestyles of all creatures. Conservation of natural resources is now usually embraced in the broader conception of conserving the earth itself by protecting its capacity for self-renewal.         Finally, the aim of this paper is to highlight the importance of the role of society members in the conservation of our natural or environmental resources.
