BACKGROUND

With the utility of nail dermoscopy to supplement the diagnosis of onychomycosis, studies have been done in describing common findings. However, most of these were based in Europe and the Americas. Given the geographical variation of onychomycosis, a local study is needed.

OBJECTIVE

The general objective of this cross-sectional study is to determine the different patterns among the clinical subtypes of laboratory diagnosed onychomycosis patients seen at the Philippine General Hospital (PGH).

METHODOLOGY

Clinically suspected Filipino onychomycosis patients seen at the PGH - Department of Dermatology, and at the PGH inpatient wards were recruited. All patients underwent the following: direct KOH microscopy, fungal culture studies, and nail clipping with PAS staining.

RESULTS

A total of 75 samples were included; 93.33% of the samples were categorized as DLSO subtype, 5.33% as TDO, and 1.33% as PSO. The three most common onychoscopic patterns were subungual hyperkeratosis (93.33%), chromonychia (85.33%), and longitudinal striae in 81.33%. KOH was positive in 57.33% of the cases, cultures in 38.67% and PAS stain in 80%. Onychoscopic pattern was not associated with clinical type of onychomycosis and causative organism. Negative KOH result was associated with linear edges (p=0.02).

CONCLUSION

Among patients with clinical and laboratory diagnosed onychomycosis, linear edges and jagged proximal edges were associated with negative KOH microscopy and fungal CS, respectively. Hence, in situations where such examinations are negative despite a strong clinical suspicion of onychomycosis, the above onychoscopic findings can be used for empirical diagnosis.

OBJECTIVETo investigate the relative effects of degree and distribution of body fat with several cardiovascular disease (CVD) risk factors in elderly Chinese subjects.

METHODSOne hundred and thirty-five elderly Chinese individuals (age range, 60-65 y) without any history of significant renal, hepatic or cardiac disease were recruited. Seated blood pressure, anthropometric and fasting plasma biochemical parameters were measured. Student's t-test was used to compare the differences in biochemical and anthropometric markers between cohorts.

RESULTSMales were heavier (64.6 +/- 8.6, 57.2 +/- 8.2kg, P < 0.001), taller (1.65 +/- 0.06, 1.51 +/- 0.05 m, P < 0.001) and their greater body fat was predominantly deposited centrally (Waist-to- hip ratio, 0.91 +/- 0.06, 0.88 +/- 0.07, P < 0.05). Females were more generally obese with increased body mass index (BMI, 23.8 +/- 4.6, 25.0 +/- 3.5 kg/m2, P < 0.05) and percentage body fat [26.3% (24.5%-28.1%) vs 37.2% (36.0%-38.9%), P < 0.001] than the males. However, despite an 11% higher proportion of body fat in females, no significant differences were identified in blood pressure, lipid profile, indices of insulin resistance or albumin-to-creatinine ratios.

CONCLUSIONIt is likely that central adiposity contributes disproportionately to these metabolic disorders in males even though they are much leaner than elderly Chinese females.

Objective. Classic high-grade osteosarcoma is uncommon in preadolescents (less than or equal to 10 years of age). The possibilities of clinicopathologic differences from the typical adolescent osteosarcoma patient have been raised. We sought to compare the presentation, treatment and survival of this subgroup of patients with published rates in order to determine if there is a need to use a treatment regimen different from that for regular adolescent osteosarcoma patients. Methods. Records of the University of the Philippines-Musculoskeletal Tumor Unit (UP-MuST) over a 15-year period (1993-2008) were reviewed and data collected on patients 10 years and younger with biopsy-proven classic high-grade intramedullary osteosarcoma who underwent complete treatment by the Unit. Demographics and survival rates were then compared with published rates for preadolescent and regular adolescent osteosarcoma cases. Results. There were fourteen patients; (6M:8F; age: 4-10 years). The most common presentation was a painful mass in the distal femur (8); the tumors most commonly had osteoblastic histology (12). Treatment consisted of neoadjuvant chemotherapy, wide surgical excision through ablation (9) or limb-saving surgery (5), and postoperative chemotherapy. There was a good histologic response (over 90% tumor necrosis) in four patients. Seven patients are ANED (alive no evidence of disease) 25 to 186 months after diagnosis. Five-year survival estimate is 52%, compared to a dismal 5 to 10% 15 years ago. Conclusion. Clinicopathologic presentation, clinical course, and overall survival in this subgroup of patients are comparable with published results for both preadolescent and adolescent osteosarcoma patients. There is no need to alter the present treatment regimen for this group of young patients.

OBJECTIVES: This study aimed to develop and validate a simple questionnaire for chronic neuropathic pain that can be administered as a screening tool by general practitioners and internists in order to help them identify patients with probable neuropathic pain.
METHODS: Following a development phase and a pilot study, the revised version of the screening tool which included eleven descriptors associated with neuropathic pain both in English and Filipino languages was validated on 120 consecutive patients with any type of pain except psychogenic pain, recruited in the out-patient clinics of six hospitals. The questionnaire was validated by assessing the sensitivity, specificity, positive and negative predictive value of each item and the overall questionnaire. The internal consistency of the questionnaire items was assessed using the Kuder-Richardson formula 20.
RESULTS: Overall, the internal consistency of the SigN-PQ using the Kuder-Richardson formula 20 was 0.7837; the sensitivity was 91.89% with specificity of 80.22%, PV (+) was 65.38% and PV(-) was 96.0%. For the English version, the descriptors with the highest scores were burning (Sensitivity: 100%, Specificity: 93%) and electricity-like (Sensitivity: 100%, Specificity: 93%). For the Filipino version, mainit (burning) has the highest sensitivity of 88% with specificity of 82.6%, followed by gumagapang (tingling) with sensitivity of 86.96% and specificity of 85.42%. The sensation of saksak (stabbing) and hiwa (lancinating) have the lowest sensitivity, 60% and 54% respectively, although their specificity scores are high. Since this study is a validation of a screening tool for neuropathic pain, the investigators decided to choose descriptors with higher sensitivity. Thus, in the final version of the SignN-PQ, the descriptors saksak and hiwa were removed.
CONCLUSION: The SigN-PQ Neuropathic Pain Questionnaire has a high overall sensitivity of 91.89% and specificity of 80.22%. The pain descriptors in the questionnaire are consistent with the descriptors cited in the literature. It is a valid screening instrument for neuropathic pain that can be easily incorporated in the daily practice of general practitioners and internists.

OBJECTIVE: This study aimed to determine the knowledge, attitudes and practices (KAP) of a selected population of patients on herbal dietary supplements (HDS).
METHOD: Methodological triangulation was used to generate a conceptual framework on HDS KAP. A survey of 175 patients was performed to measure knowledge and attitudes regarding HDS and SPSS was used for data analysis. Inverviews and focus group discussions (FGDs) were conducted to further explore the attitudes and practices, and constant comparison method was used for analysis of responses.
RESULTS: Respondents were generally aware of HDS. Majority of survey respondents believed that HDS are different from conventional drugs (52.0%, p<0.05). However, knowledge on the role of the Food and Drug Administration (FDA) in regulating HDS and understanding of "No Approved Therapeutic Claims" were poor.
The attitude toward HDS was generally positive. Majority (64.0%, p<0.05) were positive toward their perceived health benefits as claimed for the prevention of diseases, while a smaller percentage (46.9%, p<0.05) believed in their benefit for the treatment of diseases. A favorable attitude regardings HDS safety was observed due to the idea of their being "herbal" and "natural".
Among the survey respondents, only 22% were HDS users. Family was shown to promote use while cost deterred their use.
CONCLUSION: Individual knowledge and attitudes on HDS exert significant influence toward HDS practices. Factors that promote use are poor knowledge and positive attitudes toward HDS. Good knowledge seems to lead to judicious use or non-use.

OBJECTIVE: This paper aims to provide concise background information regarding the state of noncommunicable diseases (NCDs) and their risk factors as well as the existing efforts to address them in the Philippines in the last 25 years.

METHODS: A desk review of documents and literature review as well as analyses of available statistical data and several consultations with involved government agencies have been made to come up with summary figures and tables.

RESULTS: NCDs as well as metabolic conditions that can potentially lead to NCDs are on the rise in the last score of years. The Philippines, through the Department of Health, has been visionary in leading various projects and activities to fight NCDs over the last two decades, and its efforts are slowly paying off: the prevalence of tobacco use and that of hypertension have decreased over the last 5 years. NCD mortality (including premature deaths) and prevalence of behavioral risk factors, however, generally remain high, and the Philippines needs to accelerate whole-of-society and whole-of-government actions to sustain the gains and attain its NCD targets in the next 10 years or so.

CONCLUSION: The need to strengthen health system interventions and promote accountability of various sectors in addressing NCDs and its risk factors in the country arises. The development of a multisectoral action plan on NCD prevention and control is needed to halt the rise of NCDs in the country.

Objective: To analyze the characteristics of super-antigen (SAg) of group A Streptococcus pyogenes (GAS), isolated from patients with scarlet fever or pharyngeal infections in Beijing between 2015-2017. Methods: Throat swab specimens from patients with scarlet fever or pharyngeal infections were collected and tested for GAS. Eleven currently known SAg genes including SpeA, speC, speG, speH, speI, speJ, speK, speL, speM, smeZ and ssa were tested by real-time PCR while M protein genes (emm genes) were amplified and sequenced by PCR. Results: A total of 377 GAS were isolated from 6 801 throat swab specimens, with the positive rate as 5.5%. There were obvious changes noticed among speC, speG, speH and speK in three years. A total of 45 SAg genes profiles were observed, according to the SAgs inclusion. There were significant differences appeared in the frequencies among two of the highest SAg genes profiles between emm1 and emm12 strains (χ(2)=38.196, P<0.001; χ(2)=72.310, P<0.001). There also appeared significant differences in the frequencies of speA, speH, speI and speJ between emm1 and emm12 strains (χ(2)=146.154, P<0.001; χ(2)=52.31, P<0.001; χ(2)=58.43, P<0.001; χ(2)=144.70, P<0.001). Conclusions: Obvious changes were noticed among SAg genes including speC, speG, speH and speK from patients with scarlet fever or pharyngeal infections in Beijing between 2015-2017. SAg genes including speA, speH, speI and speJ appeared to be associated with the emm 1 and emm 12 strains. More kinds of SAg genes profiles were isolated form GAS but with no significant differences seen in the main SAg genes profiles, during the epidemic period.

Aims: The specific aim of this study was to evaluate for the first time the phytochemical constituents, functional group assignment, and antibacterial activities of the Philippine green-leafed Acalypha amentacea Roxb. (Maslakot-Ambulong), a wildcrafted medicinal plant of local traditional healers in the southern most region of Mindoro province. Methodology and results: Aqueous leaf extracts of A. amentacea Roxb. were lyophilized and subjected to qualitative phytochemical screening and FT-IR analysis. The antibacterial activity of the plant using agar-well diffusion assay revealed highest Zone of Inhibition (ZOI) in 500 mg/mL concentration for Staphylococcus aureus (21.78 mm), Escherichia coli, (21.36 mm), Serratia marcescens (21.90 mm), Klebsiella pneumoniae (21.44 mm), and Enterococcus faecalis (20.52 mm) among other concentrations suggesting a dose dependent bioactivity. Also, compared to the antibiotic Rifampicin, A. amentacea Roxb. demonstrated better bioactivity against all the selected bacteria except S. aureus (p<0.05) and comparable to Ofloxacin when against E. faecalis. The minimum inhibitory concentration (MIC) of the extract was found to be at 15.6 mg/mL for all the bacteria except for S. marcescens with 31.25 mg/mL as MIC. The bioactivity of the plant may be accounted to the presence of alkaloid, phenol, flavonoid, tannin, and saponin which were supported by its functional groups like carboxylic acid, alcohols, amine, conjugated alkene, aromatic esters, and alkyl aryl ether. Conclusion, significance and impact of study The results of this investigation, proved that A. amentacea Roxb. has bioactive antibacterial principles against the selected microorganisms. This also confirms its potentiality as a new source of antibacterial agents.

The Schmallenberg virus (SBV) is an orthobunyavirus that causes abortions, stillbirths, and congenital defects in pregnant sheep and cattle. Inactivated or live attenuated vaccines have been developed in endemic countries, but there is still interest in the development of SBV vaccines that would allow Differentiating Infected from Vaccinated Animals (DIVA). Therefore, an attempt was made to develop novel DIVA-compatible SBV vaccines using SBV glycoproteins expressed in baculovirus. All vaccines and phosphate buffered saline (PBS) controls were prepared with adjuvant and administered subcutaneously to cattle at 6 month of age. The first trial included 2 groups of animals vaccinated with either carboxyl-terminus glycoprotein (Gc) or PBS and boosted after 2 weeks. In the second trial, 3 groups of cattle were administered either Gc, Gc and amino-terminus glycoprotein (Gn), or PBS with a booster vaccination after 3 weeks. The animals were challenged with SBV 9 days after the booster vaccination in the first study, and 3 weeks after the booster vaccination in the second study. Using a SBV Gc-specific enzyme-linked immunosorbent assay, antibodies were first detected in serum samples 14 days after the first vaccination in both trials, and peaked on days 7 and 9 after the booster in the first and second trials, respectively. Low titers of neutralizing antibodies were detected in serum from only 3/6 and 2/4 animals in the first and second trial, respectively, at 14 days after the first vaccination. The titers increased 2 to 3-fold after the booster vaccination. SBV-specific RNA was detected in the serum and selective tissues in all animals after SBV challenge independent of vaccination status. The SBV candidate vaccines neither prevented viremia nor conferred protection against SBV infection.

BACKGROUND: Several trials on relapse rates on duration of multibacillary regimens have varying results. OBJECTIVE: To compare the relapse rate among smear-positive Leprosy patients receiving 12 blister packs of multibacillary drug therapy and 24 blister packs of multibacillary drug therapy. METHOD: A review of records of smear positive Leprosy patients seen from 2002 to 2006 was done. Demographic, clinical and therapeutic data were collected. Bacteriologic index was determined from Leprosy Laboratory records. RESULT: A total of 391 patients were found to have complete records for review and analysis. Relapse rate was 11.9%(28) for patients who received 12 blister packs and 1.91%(3) for patients who received 24 blister packs and the difference was found to be statistically significant (p<0.01). Distribution of relapse was statistically significant according to age (p<0.01), bacteriologic index (p<0.01) and clinical spectrum (p<0.01). CONCLUSION: Relapse rates shown among smear positive leprosy patients receiving 12 blister packs vs. those receiving 24 blister packs was statistically higher which differs from previously published studies. Significant predictors were clinical spectrum, bacteriologic index of >3.5, and >4 and number of blister packs.
