The RAMA Ped Card: Does it work for actual weight estimation in child patients at the emergency department / 世界急诊医学杂志（英文）

BACKGROUND:In emergency conditions, the actual weight of infants and young children are essential for treatments. The RAMATHIBODI Pediatric Emergency Drug Card or RAMA Ped Card has also been developed to estimate actual weight of the subjects. This study aimed to validate the RAMA Ped Card in correctly identifying the actual weight of infants and young adults. METHODS:This study was a prospective study. We enrolled all consecutive patients under 15 years of age who visited the emergency department (ED). All eligible patients' actual weight and height were measured at the screening point of the ED. The weight of each patient was also measured using the unlabeled RAMA Ped Card. The Cohen's kappa values and agreement percentages were calculated. RESULTS:During the study period, there were 345 eligible patients. The RAMA Ped Card had a 61.16％ agreement with the actual weight with a kappa of 0.54 (P<0.01), while the agreement with the actual height had a kappa of 0.90 and 91.59％ agreement. Sub-group analysis found kappa scores with good range in two categories:in cases of accidents and in the infant group (kappa of 0.68 and 0.65, respectively). CONCLUSION:The RAMA Ped Card had a fair correlation with the actual weight in child patients presenting at the ED. Weight estimation in infant patients and children who presented with accidents were more accurate.

Eosinophilic meningitis caused by Angiostrongylus cantonensis: an emergent disease in Brazil

Eosinophilic meningitis (EoM) is an acute disease that affects the central nervous system. It is primarily caused by infection with the nematode Angiostrongylus cantonensis. This infection was previously restricted to certain Asian countries and the Pacific Islands, but it was first reported in Brazil in 2007. Since then, intermediate and definitive hosts infected with A. cantonensis have been identified within the urban areas of many states in Brazil, including those in the northern, northeastern, southeastern and southern regions. The goals of this review are to draw the attention of the medical community and health centres to the emergence of EoM in Brazil, to compile information about several aspects of the human infection and mode of transmission and to provide a short protocol of procedures for the diagnosis of this disease.

Specificity of immunoblotting analyses in eosinophilic meningitis

Angiostrongylus cantonensis and Gnathostoma spinigerum are the two most common causative parasites of eosinophilic meningitis (EOM). Serological tests are helpful tools for confirming the identity of the pathogen. Recent reports determined the specificity of such tests by using normal healthy controls. There have been limited studies done to rule out the cross-reactivity between these two causative parasites of EOM. This study aims to assess the specificity of the serological test in EOM by using each condition as a control for the other. Thirty-three patients with a diagnosis of EOM were enrolled. Sera from 22 patients with a positive 29-kDa antigenic diagnostic band of A. cantonensis were tested for the 21 and 24-kDa antigenic bands of G. spinigerum. Similarly, sera of 11 gnathostomiasis patients were tested for the 29-kDa diagnostic band for A. cantonensis. Only one patient in the angiostrongyliasis group had a positive result for the 21 and 24-kDa antigenic bands of G. spinigerum, while no gnathostomiasis patients showed a positive result for the 29-kDa antigenic band of A. cantonensis. The specificity of the 21 and 24-kDa antigenic bands for gnathostomiasis and the 29-kDa antigenic band for A. cantonensis was 95.5 percent and 100 percent, respectively. The antigenic bands for the diagnosis of gnathostomiasis and angiostrongyliasis in EOM were highly specific.

Prevalence and recognition of geriatric syndromes in an outpatient clinic at a tertiary care hospital of Thailand.

Background: Geriatric syndromes are a series of clinical conditions in the elderly that do not fit into distinct categories. They affect the quality of life of a patient and are associated with disability. Objectives: This study determined the prevalence of geriatric syndromes in an Internal Medicine Outpatient setting. It compared the prevalence of each geriatric syndrome when using a comprehensive geriatric assessment versus the routine medical assessment. Methods: One hundred twenty elderly patients of the Internal Medicine Outpatient Clinic of Srinagarind Hospital Medical School were randomly reviewed between January 2008 and May 2010. Information on baseline characteristics and the presence of a geriatric syndrome was collected. Data for 50 patients assessed using a comprehensive geriatric assessment were reviewed prospectively and data for 70 patients assessed by a routine medical assessment were reviewed retrospectively. The prevalence for each syndrome was compared between two groups. Descriptive statistics and Chi-square test were used to analyze these outcomes. Results: The mean age and sex were not different between the two groups. Comparing the comprehensive geriatric assessment and routine medical assessment groups, there were, respectively, a prevalence of 30% vs. 1% for falls, 16% vs. 19% for dementia, 24% vs. 9% for urinary incontinence, 50% vs. 17% for functional dependency, and 22% vs. 14% for depression. Each syndrome was more prevalent with increasing age and in females. Falls (RR 2.79; 95% CI, 2.07-3.75), functional dependency (RR 2.24; 95% CI, 1.51-3.33) and urinary incontinence (RR 1.79; 95% CI, 1.18-2.70) had significantly higher prevalence in the comprehensive geriatric assessment group compared with the routine medical assessment group. Conclusions: Geriatric syndromes were highly prevalent in the elderly outpatient population. Under-recognition of these syndromes with routine medical assessments is common. Therefore, routine screening of these conditions by the comprehensive geriatric assessment is recommended.

Peripheral eosinophilia as an indicator of meningitic angiostrongyliasis in exposed individuals

The diagnosis of meningitic angiostrongyliasis (MA) is based on clinical criteria. A lumbar puncture is used as a diagnostic tool, but it is an invasive procedure. The blood eosinophil levels are also assessed and used in the diagnosis of this disease. We enrolled 47 patients with serologically proven MA and 131 controls with intestinal parasite infections. An absolute eosinophil count model was found to be the best marker for MA. An eosinophil count of more than 798 cells led to sensitivity, specificity, positive predictive and negative predictive values of 76.6 percent, 80.2 percent, 58.1 percent and 90.5 percent, respectively. These data support the use of testing for high blood eosinophil levels as a diagnostic tool for MA in individuals that are at risk for this disease.

Optic neuritis caused by intraocular angiostrongyliasis.

A 21-year-old Thai man first presented with eosinophilic meningitis. One week later he developed visual impairment of the left eye with a visual acuity of 20/600. He had a Marcus Gunn pupil, constricted visual field, prolongation of visual evoked potential and the presence of inflammatory cells in the vitreous cavity of the affected eye. On funduscopic examination there was disc swelling with hyperemia of the left eye. These ocular findings are compatible with optic neuritis. The causative agent, Angiostrongylus cantonensis, was identified in the vitreous cavity. To our knowledge this is the first case of optic neuritis caused by intraocular angiostrongyliasis. Ten days after administration of corticosteroid his severe headache was resolved, and by 4 weeks the disk swelling of the left eye subsided. Eight months after treatment the visual acuity of the left eye had not improved due to permanent damage to the retinal pigment epithelium caused by the intraocular parasite.

The best criteria to diagnose metabolic syndrome in hypertensive Thai patients.

The metabolic syndrome (MS) is commonly found in clinical practice. There are many criteria to diagnose MS. The authors did a cross-sectional study to study the difference among the WHO criteria, the National Cholesterol Educational Program (NCEP) Adult Treatment Panel (ATP III), and the International Diabetes Foundation (IDF) in hypertensive patients. Between July and September 2005, 100 patients (62 women) treated at the hypertension clinic, Srinagarind Hospital were included. The WHO, NCEP A TP III and IDF criteria gave the diagnosis of MS in 37, 33, 60 cases, respectively. The IDF criteria had the significantly highest yield among those three criteria (p < 0.0001). Body mass index (BMI) was the only significant correlated with the diagnosis of MS by the IDF criteria (p-value = 0.04). It also had moderately positive correlated with waist circumference, WC (p < 0.0001, Pearson Correlation 0.58). At the cut point of BMI 23 kg/m2, we suggested the appropriate WC cut-point for Thai hypertensive men and women was 82.5 cm (32.5") and 79.5 cm (31.3"), respectively.

Seizure in non-HIV cryptococcal meningitis.

OBJECTIVE: The authors studied the prevalence of seizure in non-HIV cryptococcal meningitis. MATERIAL AND METHOD: The records of non-HIV adult patients (age >15 years) diagnosed as cryptococcal meningitis in Srinagarind Hospital (Khon Kaen University) from 1990 to 1994 were reviewed All subjects were studied for the rate, pattern, and long-term result ofseizure. RESULTS: There were 105 cases. Eight patients (7.6%) had seizures at initial presentation. The pattern of seizure of six patients was generalized tonic-clonic seizure (GTC) and the others were focal seizure. Only one case still had seizures after treatment with conventional therapy of cryptococcal meningitis. At ten years follow up, ten cases had died, one patient still had seizures (the same case that had seizures after treatment) and one case with developed GTC after improvement of meningitis. CONCLUSION: GTC was the common pattern of seizure in non-HIV cryptococcal meningitis and mostly controlled by standard regimen of therapy for cryptococcal meningitis without any antiepileptic drugs.

A case of Miller Fisher syndrome with anti GQ1b in Thailand.

Miller-Fisher syndrome (MFS) is a rare variant of Guillain-Barré syndrome (GBS) and is characterized by the clinical triad of ataxia, ophthalmoplegia, and areflexia. The incidence rate in Thailand has not been established but it occurred approximately 1-5% that of GBS. Here, the authors report a Thai patient diagnosed as MFS that had a positive test of antibodies against the ganglioside GQ1b. These antibodies have diagnostic and pathogenic importance to MFS because of high sensitivity and specificity. All other investigations, such as cerebrospinal fluid analysis, electrophysiological studies, and imaging studies had no significant abnormalities. The patient was successfully treated with intravenous immunoglobulin and fully recovered within one month. After eighteen months follow-up, he is still healthy and has had no recurrent symptoms.

The endoscopic-pathologic findings in intestinal capillariais: a case report.

A 27-year-old Thai man presented with chronic watery diarrhea for 2 years. The diagnosis of capillariasis was made by enteroscopy after negative repeated stool tests. Here, the authors reported the first case of abnormal endoscopic finding of intestinal capillariasis. It showed segmental erythematous and swelling of proximal jejunal mucosa with an area of superficial erosion covered by exudates. The parasitic eggs were identified in jejunal content and worms were identified in jejunal mucosa. He was successfully treated with albendazole.

Eosinophilic meningitis associated with angiostrongyliasis: clinical features, laboratory investigations and specific diagnostic IgG and IgG subclass antibodies in cerebrospinal fluid.

Eosinophilic meningitis (EOM) associated angiostrongyliasis mostly induced by the nematode Angiostrongylus cantonensis, is a common disease with worldwide prevalence. Heavy infections can lead to chronic disabling disease and even death. This study was conducted to shed light on the overall specific IgG antibody response as well as the specific IgG antibody subclass responses in cerebrospinal fluid (CSF) of patients with EOM. Fifteen patients with EOM associated with angiostrongyliasis were included in the study. Sera were screened by immunoblotting for the presence of IgG antibody to the 29 kDaA. cantonensis antigenic polypeptide. CSF was examined by ELISA for the presence of specific IgG and IgG subclass antibodies. Patients presented with headache (100%), neck stiffness (20%), fever (40%), nausea (87%), vomiting (73%), paresthesia (7%), and muscle weakness (7%). Seven of 15 (47%) patients showed peripheral blood eosinophilia and all patients presented with eosinophils in CSF. A sensitivity of 80 % was obtained by combining the diagnostic values of immunoblotting in sera and IgG and IgG subclasses-based ELISA in CSF. The combination of a history of eating raw or semi-cooked infected foods, clinical features, complete blood count, differential cell counts, CSF profiles, and serum and CSF antibodies to A. cantonensis can be used to increase the sensitivity for the diagnosis of human angiostrongyliasis.

Communicating hydrocephalus as a complication of eosinophilic meningoencephalitis.

The authors reported an adult patient with communicating hydrocephalus in eosinophilic meningoencephalitis. He presented with localized peritonitis and then developed eosinophilic meningoencephalitis. Angiostrongylus cantonensis was the causative agent. This was confirmed by the positive serology test. His consciousness did not recover after supportive treatment. The MRI of the brain showed diffuse enlargement of the ventricular system two weeks after the diagnosis was made. The parameters for hydrocephalus were measured and were compatible with the Gyldensted's criteria.

Reversible posterior leukoencephalopathy caused by azathioprine in systemic lupus erythematosus.

The authors report a case of systemic lupus erythematosus with posterior leukoencephalopathy who presented with headache, tonic-clonic seizure, loss of consciousness and bilateral loss of vision, after taking azathioprine for three weeks. The patient had hypertension with normal eye grounds. The brain CT showed a hypodensity lesion at both bilateral occipital lobes, mainly in the white matter The symptoms and follow-up MRI were improved after the control of hypertension and discontinuation of azathioprine.

Acetylcholine receptor antibody in Thai generalized myasthenia gravis patients.

The authors studied acetylcholine receptor antibody (AChR Ab) in twenty-six Thai patients diagnosed as having generalized myasthenia gravis and fifteen control cases. AChR Ab assay was done by radio-immunoassay technique and reported by titer in nmole/L. The positive result was defined by titer more than 0.5 nmole/L. In the myasthenia gravis group, age ranged from 18 to 64 years old with mean of 34 years old. The female: male ratio was 4.2:1. Duration of disease before taking blood sample ranged from 1 month to 14 years with a mean of 3.9 year The AChR Ab could be detected in 21 out of 26 patients (80.7%). In the control group, tests were all negative. The results of the test made the sensitivity of 80.7% and specificity of 100%. The positive predictive value was 100%, the negative predictive value was 75%, and the prevalence was 60.3%. There was no correlation between AChR Ab titer and clinical features. This test is a very valuable test in case of uncertainly in the diagnosis of myasthenia gravis.

Aspirin therapy as primary prevention in hypertensive patients at Srinagarind hospital.

Aspirin is now a useful therapy for both primary and secondary prevention for cardiovascular events especially in diabetic patients. Hypertension is also one of the major atherosclerotic risk factors. The authors studied the rate of aspirin use as primary prevention in hypertensive cases at Srinagarind Hospital, Khon Kaen University. There were 164 of 231 hypertensive patients who were aged over 50 years old and met the criteria for aspirin therapy with 2003 ESHs guideline. Only 18.9% (31 of 164 cases) were prescribed aspirin. The most common dose of aspirin was 60 mg/day which was lower than the suggested dose. Within one-year follow up, there was no serious side effects of the aspirin such as upper gastrointestinal bleeding.

Appropriateness of intravenous loading dose of phenytoin treatment in Srinagarind Hospital.

Intravenous loading dose of phenytoin treatment (ILP) is a useful treatment but may cause serious adverse events. The present study assessed the appropriate use of ILP in Srinagarind Hospital. The authors reviewed all charts that ILP was ordered between January 1st, 2000 and December 31st, 2001, about indication, the infusion rate, and side effects. There were 206 cases treated with ILP Thirty-two cases (15.7%) received inappropriate treatment by ILP The most common indication was primary prophylaxis before brain surgery. There were 7 cases that developed side effects with 5 cases of high blood phenytoin level. These data showed that physicians should consider more carefully the use of ILP.

Health status of health care workers at Srinagarind Hospital: experience from the Annual Health Check-up Program.

The authors conducted this study to evaluate the efficacy of a health check-up program and the health status of health care workers at Srinagarind Hospital, Faculty of Medicine, Khon Kaen University. The authors reviewed all yearly-check up charts of personnel who worked at Srinagarind Hospital from 2002 to 2003 including history taking, physical examination, and laboratory testings. There were 606 office workers and 1,024 nursing staff enrolled The mean ages of both groups were 38.9 and 36.5 years old, respectively. The office workers visited physicians significantly more often than the nursing staff (553 of 606 vs 271 of 1,024; p-value = 0.00). Obesity was found much more in office workers (127 of 472 versus 129 of 749). There were significant differences between the groups on impaired fasting plasma glucose, DM, HT, high cholesterol level, high triglyceride level, and significant elevation of ALT or AST (all p-value = 0.00). In the obese group, there was also a significantly higher number of cases who had high blood pressure, defined as IFG or DM, high cholesterol level, and high triglyceride level (p-value = 0.00) except the significant elevation of ALT or AST level. Cases of obesity with significant elevation of hepatic enzyme had many atherosclerotic risk factors. Therefore, metabolic derangements are the important problem for health care workers.

C reactive protein for differentiating bacterial from aseptic meningitis in Thai patients.

OBJECTIVES: To evaluate the efficacy of serum CRP level differentiating between bacterial and aseptic meningitis in Thai patients. MATERIAL AND METHOD: The authors measured the serum CRP level in patients who were diagnosed clinically as bacterial and aseptic meningitis. RESULTS: The authors evaluated 32 subjects, 12 with bacterial meningitis (all males) and 20 with aseptic meningitis (13 males, 7 females). The mean serum CRP level in the bacterial meningitis and aseptic meningitis group was 209.25 +/- 105.34 (range, 65 to 420) and 67.05 +/- 40.81 (range, 10 to 169) mg/L, respectively (p < 0.001). CONCLUSIONS: Serum CRP can help differentiate between bacterial and aseptic meningitis.

Etiologies and treatment outcomes for out-patients with community-acquired pneumonia (CAP) at Srinagarind Hospital, Khon Kaen, Thailand.

Most patients with community-acquired pneumonia are treated as out-patients with empirical therapy, since initially the etiologic agent is unknown. We prospectively assessed the etiologies and treatment outcomes of pneumonia from February 2003 to 2004 at ambulatory clinics. Forty-four patients were included with a mean age of 49.2 (SD 18.2) years. The male to female ratio was 1:1.4. The incubation period was 6.9 (SD 4.4) days. Half of the patients were healthy. Asthma and COPD were common in patients with underlying diseases. The etiologic diagnosis was determined by a sputum culture and a serology test of paired serum samples. Hemo-culture produced no growth in any patients. Atypical pathogens and H. influenzae were the most common finding, each occurring in 31.8% of the patients followed by S. pneumoniae and H. parainfluenzae (27.3% each). Twenty-two patients were infected with multiple pathogens. C. pneumoniae was the most common co-infecting pathogen. Two of 12 S. pneumoniae isolates were penicillin resistant. Nine of 14 H. influenzae isolates were cotrimoxazole resistant and 8 of 14 were not sensitive to erythromycin. For H. parainfluenzae, 11 of 12 isolates were not sensitive to erythromycin, and 7 of 12 were not sensitive to cotrimoxazole. Oral antibiotics were prescribed as out-patient treatment. Forty patients (90.9%) improved, with symptoms-score improvement averaging 6.4 days. Four patients got worse and needed a change of antibiotics, the symptoms usually worsen within 3-5 days. We conclude that, antibiotics for CAP out-patients should cover atypical pathogens, H. influenzae, S. pneumoniae and H. parainfluenzae. If the clinical symptoms do not respond after 3-5 days of out-patient treatment, resistance or an unusual organism (eg B. pseudomallei) should be considered.
