Background: Nummular headache is a new category of primary headache disorder characterized by consistent location, size, and shape of painful areas. The pathogenesis is uncertain. Bifocal painful areas are rare manifestations but may expand the clinical diversity of nummular headache. Methods: The clinical characteristics of 5 bifocal nummular headache patients were reported and those of 11 patients in previous studies were reviewed. Bifocal nummular headache was classifi ed into two types. Type I was defi ned as a simultaneous activation of two painful areas while type II was defi ned as two painful areas occurring in different times. Results: All 16 patients were female, with mean age of onset and initial presentation of 54.7 years and 58.2 years, respectively. There were seven type I and nine type II patients. The parietal area, especially the tuber parietale, was the leading site of involvement in both types of patients. The shape and size of painful areas were also similar between these two groups. There was an equal frequency of ipsilateral and contralateral painful areas. The pain intensity was similar in both types of patients but was milder in new painful areas than in previous painful areas in type II patients. Conclusions: Bifocal nummular headache suggests a central role of nummular headache but does not debunk the peripheral theory of nummular headache. The accumulated fi ndings in bifocal NH patients do not support a generalization of pain occurrence or a reproduction of local process of epicranial neuralgia at multiple sites in nummular headache.

Pneumonia is primarily a disease that is usually managedmedically with antibiotics. However, in rare cases it mayprogress to necrotising pneumonia, which is an uncommonbut severe complication of bacterial pneumonia. This caseillustrates a typical case of necrotising pneumoniacomplicated with parenchymal and pleural complicationsuch as empyema, pneumothorax with possiblebronchopleural fistula. Early consultation with thoracicsurgeon can be life-saving.

Acrodermatitis enteropathica (AE) is a rare genetic autosomal recessive disorder characterised byperiorificial inflammatory rash, diarrhoea and hair loss. Hereby, we report 3 cases of acrodermatitisenteropathica.

Hepatic tuberculosis (HTB) is an uncommon manifestation of tuberculous infections, and there has been no proven causal link between HTB and hepatocellular carcinoma (HCC). We herein present a rare case of a synchronous presentation of HTB and HCC within a single hepatic mass. A 57-year-old Chinese gentleman with recently diagnosed sigmoid adenocarcinoma was found to have a left lower lobe pulmonary nodule and solitary hepatic mass on staging computed tomography. Biopsies showed the hepatic mass to have both HTB and HCC components. This serves as a reminder that HTB is an important differential to consider for space-occupying lesions in the liver. Histological evaluation of suspected hepatic malignancies is recommended to exclude the presence of HTB in appropriate clinical settings.

PURPOSE: Cockroaches are the second leading allergen in Taiwan. Sensitization to Per a 2, the major American cockroach allergen, correlates with clinical severity among patients with airway allergy, but there is limited information on IgE epitopes and tissue localization of Per a 2. This study aimed to identify Per a 2 linear IgE-binding epitopes and its distribution in the body of a cockroach. METHODS: The cDNA of Per a 2 was used as a template and combined with oligonucleotide primers specific to the target areas with appropriate restriction enzyme sites. Eleven overlapping fragments of Per a 2 covering the whole allergen molecule, except 20 residues of signal peptide, were generated by PCR. Mature Per a 2 and overlapping deletion mutants were affinity-purified and assayed for IgE reactivity by immunoblotting. Three synthetic peptides comprising the B cell epitopes were evaluated by direct binding ELISA. Rabbit anti-Per a 2 antibody was used for immunohistochemistry. RESULTS: Human linear IgE-binding epitopes of Per a 2 were located at the amino acid sequences 57-86, 200-211, and 299-309. There was positive IgE binding to 10 tested Per a 2-allergic sera in 3 synthetic peptides, but none in the controls. Immunostaining revealed that Per a 2 was localized partly in the mouth and midgut of the cockroach, with the most intense staining observed in the hindgut, suggesting that the Per a 2 allergen might be excreted through the feces. CONCLUSIONS: Information on the IgE-binding epitope of Per a 2 may be used for designing more specific diagnostic and therapeutic approaches to cockroach allergy.

INTRODUCTIONThe aim of this study is to report normative data for the Short-Form 36 version 2 (SF-36v2) for assessing health-related quality of life, in the Singapore general population.

MATERIALS AND METHODSData for English and Chinese-speaking participants of the Singapore Prospective Study Programme were analysed. The SF-36v2 scores were norm-based with the English-speaking Singapore general population as reference and reported by age (in decades), gender and ethnicity as well as for the 5 most prevalent chronic medical conditions. Scores were reported separately for the English and Chinese language versions.

RESULTSA total of 6151 English-speaking (61.5% Chinese and 19.2% Malay) and 1194 Chinese-speaking participants provided complete data. Mean (SD) age of all participants was 49.6 (12.58) years with 52.4% being women. In both languages, women reported lower scores than men on all scales. Among the chronic medical conditions, stroke had the largest impact on all English SF-36v2 scales and on 3 Chinese SF-36v2 scales (role-physical, general health and social functioning).

CONCLUSIONWe have provided detailed normative data for the Singapore English and Chinese SF-36v2, which would be valuable in furthering HRQoL research in Singapore and possibly the region.

Introduction: In Malaysia, the prevalence of missed opportunities for HIV-testing is unknown. Missed opportunities have been linked to late diagnosis of HIV and poorer outcome for patients. We describe missed opportunities for earlier HIV-testing in newly-HIV-diagnosed patients. Methods: Cross sectional study. Adult patients diagnosed with HIV infection and had at least one medical encounter in a primary healthcare setting during three years prior to diagnosis were included. We collected data on sociodemographic characteristics, patient characteristics at diagnosis, HIV-related conditions and whether they were subjected to risk assessment and offered HIV testing during the three years prior to HIV diagnosis. Results: 65 newly HIV-diagnosed patients (male: 92.3%; Malays: 52.4%; single: 66.7%; heterosexual: 41%; homosexual 24.6%; CD4 <350 at diagnosis: 63%). 93.8% were unaware of their HIV status at diagnosis. Up to 56.9% had presented with HIV-related conditions at a primary healthcare facility during the three years prior to diagnosis. Slightly more than half were had risk assessment done and only 33.8% were offered HIV-testing. Conclusions: Missed opportunities for HIV-testing was unacceptably high with insufficient risk assessment and offering of HIV-testing. Risk assessment must be promoted and primary care physicians must be trained to recognize HIV-related conditions that will prompt them to offer HIVtesting.

Objective: This study aimed to determine the effect of radiotherapy (RT) on the risk of herpes zoster (HZ) in patients with gynecological cancers via a nationwide population-based study. Methods: Based on patient data obtained from the National Health Insurance Research Database, 1928 gynecological cancer patients were identified with 1:1 matching for RT and non-RT cohorts by age, index date, and cancer type. Another cohort consisting of 964 noncancer individuals matched was used as normal control. The incidence of HZ was compared between cancer patients with and without RT. Age, comorbidities, cancer-related surgery and chemotherapy (CT), and cancer type were adjusted as confounders. Results: The risk of HZ in cancer patients was higher than that of non-cancer individuals (14.23 versus 8.34 per 1,000 person-years [PY], the adjusted hazard ratio [aHR]=1.38, p=0.044). In the cancer population, the incidence of HZ for the RT and non-RT cohorts was 20.55 versus 10.23 per 1,000 PY, respectively (aHR=1.68, p=0.009). Age >50 years was an independent factor for developing HZ. The 5-year actuarial incidence for patients receiving neither RT nor CT, RT alone, CT alone, and combined modalities was 5.4%, 6.9%, 3.7%, and 9.9%, respectively (p<0.001). In the RT cohort, the risk rose rapidly in the first year, becoming steady thereafter. Conclusion This population-based study showed that gynecological cancer patients receiving RT combined with CT had the highest cumulative risk of HZ. Health care professionals should be aware of the potential toxicities.
