Post dengue neurological complication.

Dengue infection is highly endemic in many tropical countries including Malaysia. However, neurological complications arising from dengue infection is not common; Gullain-Barre syndrome (GBS) is one of these infrequent complications. In this paper, we have reported a case in which a 39-year-old woman presented with a neurological complication of dengue infection without typical symptoms and signs of dengue fever. She had a history of acute gastroenteritis (AGE) followed by an upper respiratory tract infection (URTI) weeks prior to her presentation rendering GBS secondary to the post viral URTI and AGE as the most likely diagnosis. Presence of thrombocytopenia was the only clue for dengue in this case.

Sodium valproate induced necrotising pancreatitis: A case report.

Sodium valproate is one of the most common first-line antiepileptics prescribed for primary and secondary generalised seizures. However, serious complications associated with sodium valproate, such as acute pancreatitis, need to be considered when choosing this medication for treating epilepsy in certain populations such as children and persons with intellectual disability. We report a case of a 21-year-old man with intellectual disability who presented to the emergency department with an acute abdomen, vomiting and diarrhoea. He had to undergo an emergency exploratory laparotomy during which acute necrotising pancreatitis was diagnosed intra-operatively. We believe that the recent increase in sodium valproate dosage for his epilepsy was the cause of the pancreatitis. Carers of such persons should be adequately informed regarding possible life-threatening complications of medications prescribed to avoid delay in diagnosis and unwanted incidents.

Concepts in the management of the overactive bladder in women.

The 'overactive bladder' is a common problem affecting the elderly female population especially after the menopause. Urgency with or without urge incontinence accompanied by frequency of micturition and nocturia are presenting symptoms. The diagnosis is established after excluding other diseases of the lower urinary tract which have similar presenting features. The aetiology is multifactorial and this problem often causes physical, psychological and emotional distress to the patient. Management can be provided by primary care physicians initiating behavioral changes which include life style interventions and bladder drills with or without antimuscarinic drugs. The recalcitrant patient not responding to conventional therapy should be referred for specialist care. Non-conventional treatment using acupressure, neuromodulation and surgical methods are only instituted in indicated cases.

Enhancing doctor-patient relationship: the humanistic approach.

Doctor-patient relationship is a special kind of social. relationship where bonding is planned and carried out with the final objective of helping the patient to achieve the treatment goal. A positive therapeutic relationship encourages active participation of patient in the treatment plan, contributing to success of treatment goals and minimizing malpractice suits. The humanistic approach emphasizes the importance of love, belonging, self esteem, self expression and the final stage of self actualization-the drive to realize one's full potential. In person centered approach to therapeutic relationship, the three most fundamental elements are congruent (genuineness), unconditioned positive regards and empathy. In daily medical consultation, applying these elements can promote greater chance of success in the therapeutic process.

Understanding non ulcer dyspepsia.

Non ulcer dyspepsia is one of the most common problems encountered in primary care practice. The underlying pathophysiology of non ulcer dyspepsia is not fully understood, but it is known that this condition is associated with H. pylori infection and motility disorder. The presenting abdominal symptoms are non specific: they include bloating, belching, flatulence, excessive fullness after eating and nausea. Psychological condition such as anxiety, depression and stress do play a role in the recurrence of symptoms. Upper GI endoscopy is necessary in patients who presents with alarm symptoms suggestive of possible underlying organic condition before one makes the diagnosis of non ulcer dyspepsia. Pharmacological therapy using H2 receptor antagonist and proton pump inhibitors are effective for symptom relief. Patient's education and supportive care should be part of the management strategy in recurrent chronic dyspepsia.

Endocannabinoid system and cardio-metabolic risk.

Recent research in bio-medical science has shown an integral role of endocannabinoid system (ECS) in determining cardio-metabolic risk of human body. The mechanism is mediated through binding of endocannabinoids at the CB1 receptors. The stimulation of CB1 receptor in the brain is believed to control and mediate the effects on appetite. In normal physiology, CB1 receptors activation is responsible for energy homeostasis, govern emotions and behaviors such as anxiety, fear, appetite, food and water intake. CB1 receptors also found in peripheral tissues like liver, pancreas, skeletal muscles and adipose tissues, which play an important role in lipid and glucose metabolism. Over-activation of ECS is associated with various metabolic diseases such as dyslipidemia, insulin resistance, lipogenesis, excessive weight gain and increasing intra-abdominal obesity. All these events lead to increased cardiovascular risk. Use of selective CB1 receptor blocker such as rimonabant has shown to reduced waist circumference, better glycemic control, lower triglyceride levels, raise HDL cholesterol and over all reduction in total body fat. This drug has been recommended for patients with metabolic syndrome.

Managing pelvic inflammatory disease.

Pelvic inflammatory disease (PID) describes the clinical features of sexually transmitted pelvic infection ranging from acute salpingitis to salpingo-oophoritis and ultimately pelvic abscess. Intra-tubal adhesions and pelvic adhesive disease are the long-term sequelae of PID which may lead to both sub-fertility and tubal ectopic pregnancy. Laparoscopy is the definitive diagnostic modality, but is invasive and not suitable for routine clinical practice especially in the primary care setting. Ascending infection by Neiserria gonorrhoea, Chlamydia trachomatis and less commonly bacterial vaginosis and mycoplasma have been traditionally associated as causative pathogens in PID. As polymicrobial infections are being implicated in PID before culture and sensitivity results are available empirical treatment based on clinical guidelines is justified initially. Pre-emptive testing and treatment for woman at increased risk of chlamydia has been shown to reduce the risk of PID by up to two-thirds. It is imperative that medical practitioners have low thresholds for testing and treatment of both sexually active young women and men.

Osteoporosis: primary prevention in the community.

The incidence of osteoporosis is increasing worldwide. It has great impact on the life of the elderly population. The most significant medical consequence of osteoporosis is fragility fracture which without proper treatment will cause severe medical and psychosocial complications. The overall cost in managing osteoporosis and its related fractures is escalating. Using bone densitometry to measure bone mineral density is useful in the diagnosis of osteoporosis but it is costly and not feasible in the community. Drugs such as estrogen replacement, raloxifene and calcitonin are effective in prevention and treatment of osteoporosis but they are also expensive. Identifying modifiable risk factors such as smoking, lack of exercise, low dietary calcium and vitamin D intake and healthy life style remain strategy in the primary prevention of osteoporosis in the community.

"Postpartum morbidity--what we can do".

Postpartum is a crucial period for a mother. During this period a mother is going through the physiological process of uterine involution and at the same time adapting to her new role in the family. Many postpartum complications occur during this period. Among the important obstetric morbidities are postpartum hemorrhage, pregnancy related hypertension, pulmonary embolism and puerperal sepsis. Common surgical complications are wound breakdown, breast abscess and urinary fecal incontinence. Medical conditions such as anemia, headache, backache, constipation and sexual problems may also be present. Unrecognized postpartum disorders can lead to physical discomfort, psychological distress and a poor quality of life for the mothers. Providing quality postnatal care including earlier identification of the problems (correction) and proper intervention will help the mother to achieve full recovery and restore her functional status back to the pre-pregnancy state sooner.

Urinary incontinence in the elderly population.

Urinary incontinence is an important and common health care problem affecting the elderly population. Common types of incontinence affecting the elderly are: stress incontinence, urge incontinence, overflow incontinence and mixed type. The elderly patient suffering from urinary incontinence does not often seek treatment voluntary due to a misconception that it is part of a normal ageing process. Without treatment, urinary incontinence may lead to serious psychological and social complications such as depression, anxiety, embarrassment, low self-esteem and social isolation. Overall it is associated with significant poor quality of life for the elderly. Life style modification and behavioural therapy with or without pharmacotherapy help in improving the symptoms. Pelvic floor muscles' training is beneficial for stress incontinence in up to fifty percent of the patients. Elderly patients with urinary incontinence should be encouraged to seek treatment early, as the problem can be treated and they will have a better quality of life.

Understanding hyperemesis gravidarum.

Nausea and vomiting are common in early pregnancy affecting 70-80 percent of pregnant mothers. In a majority of women vomiting begins between 4-7 weeks of pregnancy. Nausea and vomiting are usually mild and self-limiting, however some of the mothers have a more profound course which lead to hyperemesis gravidarum. Careful clinical evaluation is necessary to exclude underlying medical illnesses or non pregnancy related causes of severe vomiting. Hyperemesis gravidarum poses health risk to both mother and baby, therefore prompt treatment should be initiated without delay. Non pharmacotherapy such as dietary modification and emotional support are useful. Pharmacotherapy with antiemetics, pyridoxine, methylprednisolone are effective and relatively safe. Severe hyperemesis with dehydration and electrolyte imbalance may need hospitalisation for electrolyte and fluid replacement.

The prevalence of functional impairment among elderly aged 60 years and above attending Klinik Kkesihatan Batu 9 Ulu Langat, Selangor.

The aim of this study was to determine the prevalence of functional impairment and its associated factors among patients aged 60 years and above attending Klinik Kesihatan Batu 9 Ulu Langat, Selangor. This is a cross sectional community health clinic based study. A total of 260 elderly patients attending the community health clinic were interviewed. They were clinically assessed for functional impairment by using the 9 item Instrumental Activities of Daily Living (IADL) scale. There were 118 (45.4%) elderly male and 142 (54.6%) elderly female with age ranging from 60 years to 92 years with the mean age of 67.5 and 65.5 years for male and female respectively. Chinese form the largest population (42.3%) followed by Malay (36.5%), Indian (19.2%) and others (2.0%). The overall prevalence of functional impairment among elderly aged 60 years and above in this study was 33.5%. Among the functionally impaired, two patients (0.8%) were totally dependent. There were significant associations between functional impairment and older age (p = 0.025), lower income group (p = 0.010), lower education level (p = 0.030) and history of chronic medical illness (p = 0.020). Functional impairment had no significant association with ethnic group, gender, occupation and living arrangement. For daily activities that were assessed, the commonest impairment was inability to perform shopping (40%) followed by impairment in climbing up staircase (36.6%) and impairment in taking medication (35%). Advanced age, lower income, lower education and history of medical illness are associated with functional impairment. Functional impairment is an important consideration in caring for the elderly patients in the community. These findings have implications in caring of the elderly in which attention need to be paid to activities such as shopping, climbing stairs and taking medication. The use of the IADL scale is feasible for screening of functional impairment among the elderly population in the community.

Hearing impairment in the elderly.

Hearing impairment is one of the most important health problems of the elderly above 60. Very often it leads to verbal communication difficulty and without treatment it can cause serious psychological and social complications such as depression and social isolation. Prebyscusis remains a leading cause of sensorineural deafness in the elderly. Elderly patient must be encouraged to seek proper hearing assessment if they face hearing difficulty. Active screening by health care workers and patient self-evaluation by answering a simple list of screening questions are possible for early detection and treatment of hearing loss in the elderly. Although hearing loss in the elderly may not have a cure, early rehabilitation helps to restore better quality of life if the problem is detected early.

Age related visual impairment in the elderly.

Visual impairment among the elderly is a major health problem. With advancing age, the normal function of eye tissues decreases and there is an increased incidence of ocular pathology. Demographic studies have shown that age is the best predictor of blindness and visual impairment. The most common causes of age related visual impairment in the elderly are presbyopia, cataracts, age related macular degeneration, primary open angle glaucoma and diabetic retinopathy. Untreated visual impairment leads to physical handicap, increased incidence of fall, depression, social isolation and dependency. Active screening for visual loss in the elderly should be part of the health examination. The elderly should be encouraged to come for formal 1-2 yearly eye assessment for early detection of visual impairment and to treat all associated problems in order to prevent permanent visual loss.

Gestational trophoblastic disease.

Gestational trophoblastic disease is a spectrum of pregnancy disorder arising from the placental trophoblastic tissues. It characterised by the secretion of a distinct tumour marker, the beta-HCG. This condition is highly curable even in the presence of metastasis. The incidence of this disease is higher in the Asian population. The major well-established risk factors for gestational trophoblastic disease are advanced maternal age and a past history of gestational trophoblastic disease. Common clinical presentations include vaginal bleeding in early trimester, uterus larger than gestational age, absence of fetal parts after 20 weeks of gestation. Ultrasonography is a reliable non-invasive tool for diagnosis of gestational trophoblastic disease in the clinical setting. All placental tissue following miscarriage or curettage should have histopathological evaluation to exclude gestational trophoblastic disease. Since this group of disorders is one of the highly curable neoplasms, early diagnosis and prompt treatment is necessary.

Recurrent vaginal candidiasis.

Recurrent vaginal candidiasis is one of the most common reasons for patients visiting their primary care doctors. Majority of the cases are caused by Candida albicans. Controlling of risk factors such as diabetes mellitus, used of broad spectrum antibiotics, contraceptive pills and steroid therapy helps in managing recurrent vaginal candidiasis. Initial 14-day course of oral azoles and followed by 6 months maintenance are effective in treating majority of the cases. Failure to treat recurrent vaginal candidiasis can lead to various bio-psycho-social complications.
