Cellular and Molecular Responses to Mechanical Expansion of Tissue.

The increased use of tissue expander in the past decades and its potential market values in near future give enough reasons to sum up the consequences of tissue expansion. Furthermore, the patients have the right to know underlying mechanisms of adaptation of inserted biomimetic, its bioinspired materials and probable complications. The mechanical strains during tissue expansion are related to several biological phenomena. Tissue remodeling during the expansion is highly regulated and depends on the signal transduction. Any alteration may lead to tumor formation, necrosis and/or apoptosis. In this review, stretch induced cell proliferation, apoptosis, the roles of growth factors, stretch induced ion channels, and roles of second messengers are organized. It is expected that readers from any background can understand and make a decision about tissue expansion.

Depression among chronic pain patients at Hospital Tengku Ampuan Rahimah, Klang.

INTRODUCTION: Despite the high prevalence rates of depression amongst chronic pain patients reported globally, the condition is often under-recognised and under-treated. Depression frequently complicates the effective management of pain and is associated with poor quality of life. This study aimed to explore the incidence of depression and its' associated factors in a sample of chronic pain patients in Malaysia. MATERIALS AND METHODS: This descriptive cross-sectional study was conducted amongst clinically diagnosed chronic pain patients from the pain management clinic of Hospital Tengku Ampuan Rahimah over a period of seven months. Socio-demographics and clinical data were obtained from patients' interview and medical records. The validated Depression Anxiety Stress Scale-21 (DASS-21) was used for screening and Mini International Neuropsychiatric Interview (MINI) was used to establish the depression diagnoses among the patients. Numeric pain intensity scale was used to assess the severity of pain. RESULTS: Eighty-three patients with a mean age of 50.4±12.50 years participated in this study. The majority of the patients were females (56.6%), married (85.5%) and being employed (49.4%). The percentage of depression was 37.4%. Depression was significantly associated with severity of pain (p<0.001) and the duration of pain (p <0.05). CONCLUSION: Almost one third of chronic pain patients in this study have depression. Depression was significantly associated with the severity and duration of pain. Depression should be regularly screened among patient with chronic pain.

Managing ‘Schizophrenia in the Midst of Schizophrenia’- The Role of Assertive Community Treatment

This case report emphasizes the role of Assertive Community Treatment (ACT)in managing a family with four members suffering from mental illness, mainly schizophrenia. We report a case of middle-aged lady who was diagnosed with treatment resistant schizophrenia (TRS) living with two other family members with the same illness and their carer who developed major depression from shouldering the burden of caring for mentally ill family members. ACT, through its holistic approach, proved to have reduced hospitalizations and improve symptom control and quality of life in this family.

Factors associated with cognitive impairment in patients with Parkinson disease: an urban study.

BACKGROUND AND AIMS: Parkinson disease (PD) is the second most prevalent neurodegenerative disorder after Alzheimer disease. Besides motor presentations, cognitive impairment is among the other likely complications as the illness progresses. This study aimed to determine the prevalence of cognitive impairment in PD and the factors associated with the cognitive impairment. MATERIALS AND METHODS: A cross-sectional, descriptive study was conducted on all PD patients at different stages of their illness, in two major tertiary hospitals in Malaysia with their caregivers, over a three month period in 2002. Patients' cognitive functions were tested using the Mini Mental State Examination (MMSE). Important sociodemographic data and relevant clinical information of the patients as well as caregivers' information on income, duration of care-giving, relationship with the patient, and other relevant variables were gathered. Patients' level of functioning was assessed using the Activities of Daily Living (ADL) index. Staging of illness was done based on the Hoehn and Yahr Scale. RESULTS: Out of 115 eligible patients, 35% were in the 60-69 age group with 57% in stage 2 of illness, A total of 29% of patients experienced various degrees of cognitive impairment , with almost half (47%) in the stage 3 and 4 exhibiting MMSE scores <24. Factors which were significantly associated with impaired cognitions were race, educational level and stage of illness. CONCLUSION: Cognitive impairment was fairly common in PD and the severity of impairment in cognition and physical functioning increased with the advancement of the illness.

Executive function and attention span in euthymic patients with bipolar 1 disorder.

This is a cross sectional comparison study to assess executive function and attention span in euthymic patients with bipolar 1 disorder. It compares the performance of these two cognitive domains in 40 patients with bipolar 1 disorder to that of 40 healthy normal subjects using Trail Making (TMT), Digit Span (Forward and Backward) and Verbal Fluency (VF) tests. The association between demographic, clinical characteristics and performance in all tests were examined. Patients with bipolar illness showed significant impairment with moderate to large effect sizes (VF = 0.67, TMT A = 0.52, TMT B = 0.81, Digit Forward = 0.97, Digit backward = 1.10) in all tasks of executive and attention functioning. These impairments are observed in the absence of active mood symptoms while duration and severity of illness are not found to have an effect on both cognitive domains. Medications received by patients with bipolar disorder have significant association with performance on executive tasks. The results of this study add on to the existing global evidence of cognitive impairment in bipolar illness despite its cross cultural differences. Its presence in the absence of mania, depression or mixed episode indicates that cognitive impairment is stable even after symptoms recovery.
