Abstract
BACKGROUND Hereditary angioedema (HAE) is a rare genetic disease with significant morbidity and mortality for which early diagnosis and effective therapy are critical. Many Asia Pacific (AP) countries still lack access to diagnostic tests and evidence-based therapies. Epidemiologic data from the AP is needed to formulate regional guidelines to improve standards of care for HAE. OBJECTIVE To investigate the estimated minimal prevalence, needs, and potential interventions for the diagnosis and management of HAE in the AP. METHODS A structured questionnaire was distributed to representative experts from member societies of the Asia Pacific Association of Allergy, Asthma and Clinical Immunology. Patient profiles and the presence of diagnostic facilities or tests, regional and national HAE guidelines, and patient support groups were reported and compared. RESULTS Completed questionnaires were received from 14 representatives of 12 member countries and territories, representing 46% of the world population. Overall minimal prevalence of HAE in the AP region was 0.02/100,000 population, with significant heterogeneity across different centers. Only one-half and one-third had registered on-demand and prophylactic medications, respectively. Few had patient support groups (58%) or regional guidelines (33%), and their existence was associated with the availability of HAE-specific medications. Availability of C1-inhibitor level testing was associated with a lower age at HAE diagnosis (P = .017). CONCLUSIONS Hereditary angioedema in the AP differs from that in Western countries. Hereditary angioedema-specific medications were registered in only a minority of countries and territories, but those with patient support groups or regional guidelines were more likely to have better access. Asia Pacific-specific consensus and guidelines are lacking and urgently needed.

Abstract
Hereditary angioedema (HAE) is an autosomal dominant disease characterized clinically by recurrent episodes of swelling in the tissues of the extremities, face, abdomen, and respiratory tract. It is most often caused by C1 esterase inhibitor (C1 INH) gene mutation. This swelling may lead to bradykinin release, resulting in recurrent, paroxysmal, painful angioedema. Blister formation is an uncommon cutaneous manifestation of HAE. Herein, we report a case of a patient with HAE who developed linear wrist blisters on her skin, with swelling, as a rare complication of HAE. She was treated with attenuated androgens (Danazol) for two weeks at our clinic, after which the blisters showed dramatic improvement. To date, only a few HAE cases have been reported across the world. Therefore, it is important to focus on and recognize the development of edema blisters as a flare of HAE, which could consequently avoid unnecessary dermatological diagnostic workup and treatment.

Abstract
Buckwheat anaphylaxis is commonly recognized in Europe and Asia, and there is only one case reported in Taiwan so far. Here, we report a case of biphasic buckwheat anaphylaxis in a 57 year-old male patient who lost consciousness twice in the same day after having buckwheat noodles. The serum test shows that Dermatophagoides pteronyssinus (Dp)immunoglobulin E (IgE) (42.4 kU/L) and buckwheat-specific IgE (81.5 kU/L) are unusually high. Although biphasic buckwheat anaphylaxis is rare, we should still be aware the second episode could be life-threatening and happen within a day after the exposure to the buckwheat antigen.

Abstract
BACKGROUND Aeroallergen sensitization may predict higher fractional exhaled nitric oxide (FeNO) levels. OBJECTIVE We evaluate cut-off values of FeNO in asthmatic children with and without positive specific immunoglobulin E (IgE) to at least one of 5 aeroallergens (Dermatophagoides pteronyssinus, Dermatophagoides farinae, cat, dog, and cockroach). METHODS 564 patients with asthma and allergic rhinitis (AR) aged 5 to 18 years were enrolled into two groups. Sensitized group included 378 children with positive IgE to at least one of 5 inhaled allergens. Non-sensitized group included 186 children. Pulmonary function tests, FeNO, eosinophil counts, and IgE levels were examined. Patients were divided into preschool age (5~6 years old), elementary school children (7~11 years old) and adolescents (12~18 years old). RESULTS In preschool children, FeNO≥15.5 ppb differentiates between non-sensitized and sensitized groups. (sensitivity 54.3%; specificity 87.5%; positive predictive value (PPV) 86.2%; negative predictive value (NPV) 57.1%; area under receiver operating characteristic curve (AUC) 0.72) Among elementary school children, the cut-off value of FeNO≥19.5 ppb showed sensitivity 66.4%; specificity 85.8%; PPV 90.5%; NPV 55.7%; AUC 0.81. In adolescents, FeNO≥27.5 ppb showed sensitivity 60.2%; specificity 85.4%; PPV 91.2%; NPV 46.1%; AUC 0.76. CONCLUSION In asthmatic children, aeroallergen sensitization appears to contribute to higher FeNO levels than those not sensitized. Cut-off values of FeNO which well discriminate asthmatic children with and without aeroallergen sensitization should be chose according to different ages.

Abstract
Generalised morphea (GM) is a subtype of localised scleroderma that usually manifests with bilateral involvement. Unilateral generalised morphea (UGM) is a rare variant of GM. This is a case report of a Taiwanese girl with UGM over the left side of her body. She presented with hyperpigmentation, tightness, and skin atrophy over the left extremities and trunk. Mild range of motion (ROM) limitation over the left knee was also noted. At the clinic, the patient was given oral prednisolone, oral methotrexate (MTX), and oral D-penicillamine. topical emollient and topical glucocorticoids were also given. The dose of oral prednisolone was tapered gradually. All symptoms were improved under the treatment and regular rehabilitation program. To date, there is very little evidence to form the basis for treatment recommendations. This case report provides a treatment option for UGM in the paediatric group without the use of intravenous methylprednisolone pulse therapy.

Abstract
BACKGROUND The recurrence rate of Henoch-Schönlein purpura (HSP) is 2.7%-30%, with varied average intervals between the first and second episodes. Few studies have explored the incidence and risk factors for recurrent HSP. METHODS We used a 16-year nationwide database to analyze the incidence of recurrent HSP. Patients with HSP were identified, and risk factors for recurrent HSP were explored. Kaplan-Meier and Cox regression model analyses were performed, and covariates were adjusted in the multivariate model. RESULTS From January 1, 1997 to December 31, 2012, among 2,886,836 individuals in the National Health Insurance Research Database, 1002 HSP patients aged < 18 years were identified. Among them, 164 had ≥2 HSP episodes (recurrence rate, 16.4%; incidence of recurrent HSP, 7.05 per 100 person-years); 83.6% patients with one HSP episode remained free of secondary HSP. The average time intervals between the first and second and second and third HSP episodes were 9.2 and 6.4 months, respectively. After adjusting for demographic parameters, comorbidities, and socioeconomic status, recurrent HSP was found to occur more frequently in patients who had renal involvement (adjusted hazard ratio, 2.41; 95% confidence interval [CI], 1.64-3.54; p < 0.001), were receiving steroid therapy for > 10 days (adjusted hazard ratio, 8.13; 95%CI, 2.51-26.36; p < 0.001), and had allergic rhinitis (adjusted hazard ratio, 1.63; 95%CI, 1.06-2.50; p = 0.026). CONCLUSIONS The annual incidence of recurrent HSP was low. However, children who had underlying allergic rhinitis, presented with renal involvement, and received steroid treatment for > 10 days should be notified regarding the possibility of recurrence.

Abstract
Background Kawasaki disease (KD) is an immune-mediated systemic vasculitis, and infection plays an important role in the pathophysiology of KD. The susceptibility to infectious disease in patients with KD remains largely unclear. This study aimed to investigate the risk of respiratory tract infection (RTI)-related hospitalizations in children with KD. Methods Data from the Taiwanese National Health Insurance Research Database was analyzed. We excluded patients with history of congenital abnormality, allergic diseases, or hospitalization history. Children with KD were selected as KD group and age- and sex-matched non-KD patients were selected as control group with 1:4 ratio. Both cohorts were tracked for one year to investigate the incidences of RTI-related hospitalizations. Cox regression hazard model was used to adjust for confounding factors and calculate the adjusted hazard ratio (aHR). Results Between January 1996 and December 2012, 4,973 patients with KD were identified as the KD group and 19,683 patients were enrolled as the control group. An obviously reduced risk of RTI-related hospitalizations was observed in KD patients (aHR: 0.75, 95% CI [0.66-0.85]). The decreased risk persisted through the first six-months follow-up period with a peak protection in 3-6 months (aHR: 0.49, 95% CI [0.37-0.64]). Conclusions KD patients had approximately half reduction of risk for RTI-related hospitalizations. The protective effects persisted for at least six months. Further studies are warranted to elucidate the entire mechanism and investigate the influences of intravenous immunoglobulin.

Abstract
BACKGROUND The EHF and ELF5 genes, located on chromosome 11p and linked to asthma phenotypes, are high-potential candidate genes conferring asthma susceptibility. The purpose of this study was to investigate the genetic association among single nucleotide polymorphisms (SNPs) of EHF and ELF5, and their relationship with asthma in the Taiwanese population. METHODS We selected and performed genotyping on 16 SNPs that encompass the genomic region of EHF and ELF5 in Taiwanese children with or without asthma. A total of 1983 children, 523 in the test group and 619 and 842 in two validation groups, were recruited for this study. RESULTS The SNP rs3910901, located in the 5' upstream region of ELF5, was found to have a weak association (p = 0.043) with asthma in the odds ratio analysis. The genotype distribution was similar in all comparison groups, but the CC genotype was more frequent in asthma patients. Logistic regression adjusted allergy comorbidity showed obviously diluted association. CONCLUSION The results indicated that SNP rs3910901 may have a minor impact on pediatric asthma in the Taiwanese population.

Abstract
Patients with X-linked hyperimmunoglobulin M syndrome (XHIGM) have a defective CD40-CD40 ligand system and further immunoglobulin class-switching. They may present with recurrent infection and malignancy involving the liver, pancreas or biliary tract. We report here a case of poorly differentiated transitional cell carcinoma in a young man with XHIGM even on regular treatment and discuss the possible pathogenesis. Given that the triggering of the CD40-CD40 ligand system has been found to improve tumor immunogenicity in recent studies, future immunotherapy targeting the CD40 ligand for these patients may be feasible to prolong their survival.

Pachydermodactyly (PDD), Greek for thick-skin-finger, is an infrequently recognized benign disorder characterized by painless fusiform swelling of the soft tissues around the proximal interphalangeal joints of the hands. Histopathologic features include increased dermal accumulation of collagen fibers. Young males are predominantly affected. PDD is quite rare with approximately 90 cumulative cases reported worldwide. We report three new cases of PDD in Taiwan, including two female patients. Except for patient 1 having the habit of cracking the knuckles, and patient 2 having a history of patent ductus ateriosus post catheterization, the histories of all three patients were unremarkable. X-ray of bilateral hands revealed no abnormal finding except for soft tissue swelling around proximal interphalangeal joints. Laboratory examinations all showed negative results. No local or systemic treatment was given to these patients to treat PDD, with the exception of non-steroidal anti-inflammatory drugs prescribed to one patient for a short period. Skin care with local irritation avoidance was explained to all three patients. The long-term outcome of PDD was benign.

Abstract
Cystic fibrosis (CF) is one of the most common autosomal recessive inherited disorders among Caucasians. Comparatively, it is considered to be a rare disease among Asians. To date, only a few cases of Taiwanese CF have been published. We report four CF cases from three families. Case 1 was the first report of CF associated with a homozygosity for the CF transmembrane conductance regulator gene (CFTR gene) mutation 3849+10kb C->T in a Taiwanese patient. Cases 2 and 3 had heterozygous c. 1898+5 G->T and heterozygous p. I1023R (novel mutation) for the CFTR gene mutation. Case 4 was homozygous for the CFTR gene mutation R553X being reported in 2005 and complicated with cor pulmonale. These four patients had received 300 mg bid aerosolized tobramycin treatment every other month.

Abstract
BACKGROUND Hereditary angioedema (HAE) is a rare, autosomal dominant inherited disease which is caused by a genetic deficiency of C1 esterase inhibitor (C1 INH). There have only been a few case reports in Taiwan to date. OBJECTIVE To describe the clinical features of type I HAE in Taiwanese patients. METHODS Three unrelated Taiwanese families with type I HAE are reported, and one case of a family from a review of PubMed was reviewed. Clinical manifestations, diagnostic examinations, management and genetic studies were analyzed. RESULTS Including this report, 19 patients had low C1 INH and low C4 levels and were diagnosed with type I HAE. Only 11 (57.9%) patients were symptomatic. Recurrent skin swelling and edema over the four extremities or trunk were reported in all symptomatic patients (100%). 45.5% of the patients recalled laryngeal attacks and one patient died from asphyxia. 18.2% of the patients experienced abdominal symptoms. The age at the beginning of clinical symptoms ranged from 5 to 30 years (mean +/- SD: 20.82 +/- 7.88 years). The diagnosis tended to be delayed (range from 1 to 39 years; mean +/- SD: 8.45 +/- 11.04 years). Nine patients had a mutant C1 INH gene, and two patients received long-term prophylaxis with danazol. CONCLUSION The prevalence of hereditary angioedema in Taiwan is low. Persons with low levels of C1 INH who were clinically symptomatic accounted for only 57.9% of the cases in our study, which is far lower than previous reports from other countries. Ethnic differences may be the reason for this finding. Further genomic studies are needed to elucidate the genetic penetrance of C1 INH deficiency in Taiwan.

Abstract
BACKGROUND AND OBJECTIVE X-linked agammaglobulinemia (XLA, also called Bruton's disease) is is an X-linked recessive disorder characterized by recurrent bacterial infections, usually occurring in the first few years of life. Here, we report the results of a BTK gene mutation screening study that was performed in Taiwanese families with the BTK gene defect to further understand the inheritance patterns of XLA patients in Taiwan and to avoid new cases of XLA within families. MATERIALS AND METHODS In this study, 52 members of 4 unrelated Taiwanese families with the BTK gene defect were enrolled. We studied the immunologic reports of 6 symptomatic living male patients with confirmed BTK gene defects and correlated the findings with their clinical symptoms. The genomic DNA of the subjects was subjected to direct sequencing mutation analysis. RESULTS We screened 52 members of 4 unrelated Taiwanese families with the BTK gene defect for BTK gene mutation and found that there were 6 symptomatic living patients with a confirmed defect, 7 symptomatic deceased patients highly suspected to have had the defect and 11 asymptomatic female carriers. CONCLUSIONS This is the first report in a series of the thorough screening for the BTK mutation and its carrier status in 4 unrelated Taiwanese families. One pedigree of our study comprises 4 generations. A complete BTK gene mutation study for the patient's family members is strongly suggested.

Abstract
BACKGROUND Scleroderma is a chronic connective tissue disease characterized by hardened or scaly skin and widespread abnormalities of the viscera, which is rare in the pediatric age group. OBJECTIVE In this study, we retrospectively reviewed 23 pediatric patients suffering systemic (SSc) and localized (LS) scleroderma. METHODS Twenty-three patients were enrolled and were diagnosed with SSc or LS from March 1993 to September 2009 in the Department of Pediatrics at Mackay Memorial Hospital in Taipei, Taiwan. These diagnoses were based on the criteria of the American College of Rheumatology and the clinical manifestations of hard skin. Data recorded included sex, age-at-onset, age-at-diagnosis, laboratory data, family history, trauma history, treatment, and outcomes. RESULTS Three patients suffered SSc and 20 patients had LS, including 16 girls and 7 boys. Mean age-at-onset was 6.55 +/- 3.28 years old. Antinuclear antibodies were positive in 15 patients. Tests for anti-Scl-70 antibodies were positive in 1 patient with SSc. One boy had en coup de sabre combined with a posterior fossa tumor. Twenty-two patients were treated with D-penicillamine. Oral prednisolone and methotrexate were added, if indicated. One girl with LS developed proteinuria after D-penicillamine treatment. All patients with localized disease ultimately documented a softening of their skin lesions. CONCLUSIONS While scleroderma is rare in children, the prognosis of SSc is poor but better than for adults. The prognosis for LS is usually benign, however, the skin may become progressively indurated and it may not only be a skin disease. No progression from LS to SSc was observed in our study.

Abstract
BACKGROUND Asthma is one of the major causes of death in otherwise healthy young individuals. However, many of these deaths may have been prevented by more aggressive treatment. To determine factors correlated with a high risk of death in Taiwanese children with atopic asthma. METHODS Taiwanese children aged 5-18 years, diagnosed with atopic asthma were enrolled in the study. Atopic asthma was diagnosed and immunoglobulin E (IgE) specific to antigens from any 1 of 8 allergens was measured (i.e. Dermatophagoides pteronyssinus, Dermatophagoides farinae, cat and dog dander, cockroach, egg white, milk and fish). High-risk asthma was defined as asthma requiring admission to a hospital or a visit to an emergency department. The study tried to determine the association of high-risk asthma with allergy-related parameters (e.g. asthma severity, asthma score, total serum IgE levels, serum levels of allergen-specific IgE, eosinophil count) and pulmonary function in Taiwanese children. RESULTS One thousand one hundred and twenty-two Taiwanese children were evaluated. Those with higher asthma severity, asthma symptom score, serum levels of IgE specific to D. pteronyssinus and D. farinae, higher total serum IgE levels, and lower FEF25-75% (forced expiratory flow, 25-75%) values were considered to be members of the high-risk asthma group. CONCLUSIONS The characterization of risk factors has enabled us to identify high-risk asthma in Taiwanese children, which will facilitate the treatment of these children in the future.

Abstract
Our aims were to evaluate the performance of an automated microfluidic immunoassay system for measuring allergen-specific IgE (sIgE) in sera against an established in vitro assay and to assess the system's diagnostic accuracy against objective clinical criteria for identifying sensitization to specific allergens in daily practice of allergy clinics. Using both the automated microfluidic-based immunoassay system (BioIC and ImmunoCAP, we measured sIgE in serum samples from 212 children who visited allergic clinics in two medical centers. Outcomes of skin prick tests (SPT) served as the clinical comparison method. The assay results of targeted allergen of BioIC have a good correlation with ImmunoCAP in the diagnosis of allergen sensitivity by patients' clinical history. When comparing the test results of the sIgE against overall allergens, in either two tests among the three assays performed showed high percentage of agreement between BioIC and ImmunoCAP (77.8%, 95% CI: 72-83.3%) but not with SPT (BioIC 64.9%, 95% CI: 58-72%; ImmunoCAP 67.5%, 95% CI: 61-74%). Using ROC analysis and SPT as quasi-standard, BioIC and ImmunoCAP have nearly the same performance of sensitivity and specificity in the confirmation of SPT results. The total and within one-class agreements of each allergen test result between BioIC and ImmunoCAP ranged between 55.2% and 99.5% with an overall average of 80.9%. Laboratory testing for sIgE can be performed on a fully automated, microfluidic cartridge system with advantages of low sample volume, simultaneously tested allergens, and with diagnostic accuracy for representative allergens equivalent to the semi-automated CAP technology.

Abstract
BACKGROUND The interleukin 17A (IL17A) gene, located on chromosome 6p and linked to asthma phenotype, is a highly potential candidate gene conferring asthma susceptibility. The purpose of this study was to investigate the genetic association between single nucleotide polymorphisms (SNPs) of IL17A and asthma in Taiwanese children. METHODS We selected and performed genotyping on nine SNPs that encompass the genomic region of IL17A in Taiwanese children with or without asthma. A total of 1939 subjects containing 1027 subjects in testing group and 931 subjects in validation group were recruited in this study. RESULTS After Bonferroni correction, SNP rs8193036 was found to have a weak association (P = 0.0074 x 9 = 0.066) in genotype frequency test. This association was confirmed by validation group. Logistic regression adjusted allergy comorbidity and gender showed a slightly weaker association. CONCLUSIONS The results indicated an independent role of IL17A promoter polymorphism rs8193036 in the association with pediatric asthma in Taiwanese population.

Abstract
The aim of this study was to evaluate the clinical and immunologic effects of sublingual-swallow immunotherapy (SLIT). A six-month, multicenter, double-blind, placebo-controlled trial was carried out in 59 patients aged 6 to 18 years with allergic rhinitis who were sensitized to mites only. Patients were randomly assigned to placebo or SLIT with a standardized Dermatophagoides pteronyssinus (D.p.)/D. farinae (D.f) 50/50 extract. Nasal symptom scores and use of medications were recorded. Skin sensitivity, mite-specific IgE, IgG4, and IgG4/IgE were evaluated before and after treatment. The skin sensitivity, total nasal symptom scores and medication consumption did not differ significantly after treatment. Specific IgG4 (both p <0.001) and IgG4/IgE to D.p. and D.f (p = 0.010, p = 0.001, respectively) increased significantly in the treatment group. Specific IgE increased significantly in both placebo and SLIT groups after treatment but did not differ between the two groups. The medication was well tolerated. SLIT did not significantly improve clinical manifestations of allergic rhinitis when used for 6 months. We demonstrated SLIT did significantly increase specific IgG4 and IgG4/IgE compared to treatment with placebo.

Abstract
BACKGROUND Hereditary angioedema (HAE) is a rare disorder characterized by recurrent attacks of localized subcutaneous or submucosal edema. It is inherited in an autosomal dominant fashion and caused by a deficiency of C1 inhibitor (C1 INH). Most patients with HAE have an absolute deficiency of C1 INH (type I HAE), whereas the rest (approximately 15%) synthesize a dysfunctional C1 INH protein (type II HAE). Mosaicism is rare in HAE. OBJECTIVE To describe the clinical manifestations, laboratory findings, and molecular genetic studies in a Taiwanese family with type I HAE with paternal mosaicism. METHODS A family that included a 34-year-old man (index patient) and his 25-year-old brother who both had recurrent peripheral angioedema was evaluated. A younger sister had died of an unexplained cause at 18 years of age. We analyzed blood levels of C3, C4, and C1 INH and sequenced the SERPING] (C1NH) gene that codes for C1 INH in 5 family members, including the parents and 3 brothers. RESULTS The 4 men in the family had a novel mutation c.3_73del, p.N1fsX34 in exon 3 of the C1INH gene, resulting in C1 INH deficiency. Although the father carried this mutant gene, he had normal serum levels of C1 INH. Based on quantitative analysis of allele dosage by DNA fragment analysis (GeneScan), the father was determined to have genetic mosaicism. CONCLUSION Parental mosaicism is a possible explanation for normal C1 INH plasma concentrations in both parents despite clinically apparent HAE in the children.

Abstract
BACKGROUND To evaluate the efficacy of prednisolone sodium phosphate oral solution plus inhaled procaterol in the treatment of acute asthma in children. METHODS Forty-three patients aged 6 to 12 years with an acute exacerbation of asthma were double-blind randomized into one of two treatment groups in a 1:1 ratio:1) prednisolone oral solution +placebo tablets + procaterol MDI or 2) prednisolone tablets +placebo oral solution + procaterol MDI, all given three times daily for 7 days. Peak expiratory flow rate (PEFR), 24-hour reflective asthma symptom scores, spirometry and pulmonary index score (PIS) were recorded before and after treatment. Net changes in PEFR, symptom score, PIS, Forced Expiratory Volume in the first second (FEV1), FEV1/forced vital capacity (FVC), forced expiratory flow between 25 and 75 percent of the forced vital capacity (FEF(25-75%)) (before and after treatment) and global assessment by the investigator and the subjects or their parents were analyzed. RESULTS The two groups were statistically similar at baseline values of these parameters. After a 7-day course of treatment, the net change of PEFR before and after treatment was significantly improved in both groups, but there was no significant difference in the net change of PEFR between the two groups (57.27+/-31.44 L/min vs. 54.29 +/-30.04 L/min, difference 2.99 +/-30.76 L/min, mean +/-SD, P=0.752). The net change in PIS and total symptom score did not differ between the two groups (P=0.091 and 0.827, respectively). Similarly, the FEV1, FEV1/FVC and FEF25-75% all improved with either treatment, and neither group was significantly superior to the other group (P=0.162, 0.48 and 0.081, respectively). Global assessment by the investigator and the subjects or their parents at the end of study indicated an essentially comparable result. CONCLUSIONS Prednisolone sodium phosphate oral solution plus inhaled procaterol is as efficacious as prednisolone tablets plus inhaled procaterol in the management of acute asthma in children.

Abstract
Hereditary angioedema (HAE) is an autosomal dominant disorder caused by a deficiency of C1 esterase inhibitor (C1-INH). Affected individuals have attacks of swelling involving almost any part of the body. We studied a family with 15 living members, including a 16-year-old girl who had 3 attacks of angioedema in 2 years. Her paternal uncle had died of asphyxiation during an attack 15 years previously. We analyzed the blood of each family member for C3, C4, and C1-INH levels and sequenced the SERPING1 (formerly C1NH) gene that codes for C1-INH. Six individuals had decreased serum levels of C4 and C1-INH, and they were all found to have a single nucleotide A deletion at codon 210 of the gene, 1210fsX210, a novel mutation that accounts for the HAE in this family.

Abstract
An 8-month-old boy developed a disseminated cutaneous mycobacterial infection at 6 months of age that responded poorly to treatment. Further immunologic study and sequence analysis showed the presence of a missense mutation in the IL2RG gene, and X-linked severe combined immunodeficiency was diagnosed. To identify the strain of the microorganism causing the cutaneous infection, polymerase chain reaction with four pairs of primers was performed on skin biopsy specimens positive for acid-fast bacilli. Sequence analysis showed 99.36% homology with a bacilli Calmette-Guérin positive control. Disseminated bacilli Calmette-Guérin disease must be considered in any infant with cutaneous mycobacterial lesions, especially those with atypical histologic findings or who are immunocompromised. Testing by polymerase chain reaction using the proper primers may help in making a precise diagnosis.

Abstract
BACKGROUND Juvenile recurrent parotitis (JRP) is a rare, recurrent non-obstructive, nonsuppurative parotid inflammation in young children with a multifactorial etiology. METHODS The records of 12 children with recurrent parotitis were retrospectively reviewed. RESULTS The age of onset ranged from 3 to 8 years (mean, 5.1 years). Each attack lasted an average of 3.5 days. The major clinical manifestations included fever (75%), swelling (100%), and pain (100%). One girl also had xerostomia and keratoconjunctivitis sicca. Her biopsy specimen from a minor salivary gland was consistent with juvenile Sjiigren's syndrome. Six patients had positive antinuclear antibodies (4 with a speckled pattern and 2 each with a homogeneous or nucleolar pattern). Bilateral sialography was performed in 9 children. The results in 4 were normal, 2 had unilateral punctate sialectasis, and 3 had bilateral sialectasis. After sialography, the frequency of recurrences significantly decreased from 5.11 to 0.56 per year (P < 0.05). CONCLUSIONS Bilateral sialography is useful for the diagnosis of JRP, but it also appears to decrease the frequency of recurrences.

Abstract
BACKGROUND AND PURPOSE Early-onset asthma has been reported to be associated with a family history of allergy and exposure to environmental factors. This study was designed to evaluate the relationship between age of onset of asthma and genetic and environmental factors with asthma severity in Taiwanese children. METHODS A group of 352 children with asthma (220 males and 132 females), ranging in age from 5 to 15 years, were enrolled in this study. The subjects were divided into 2 groups: early-onset asthma (up to and including age 3) and late-onset asthma. General characteristics including family history of allergies and exposure to domestic pets and tobacco smoke were recorded. The subjects underwent pulmonary function testing and analysis of serum immunoglobulin E (IgE), eosinophil counts, and specific IgE for common allergens. RESULTS Early-onset asthma was present in 149 subjects and late-onset asthma in 203. Family history of allergies included a sibling with asthma or urticaria predisposed to early-onset asthma (asthma, p=0.034; urticaria, p=0.024). Food and milk allergen sensitization were more common in early-onset asthma (food allergens, p=0.025; milk, p=0.034). Children with early-onset asthma had higher eosinophil counts (p=0.041). However, there was no correlation between age at onset and pulmonary function testing, the levels of total IgE and IgE specific for Dermatophagoides pteronyssinus or Dermatophagoides farinae. CONCLUSIONS A history of asthma or urticaria in a sibling is a risk factor for early-onset asthma. A greater prevalence of food allergen sensitization and high eosinophil counts are characteristic of early-onset disease.

Abstract
BACKGROUND X-linked agammaglobulinemia (XLA), characterized by a profound deficiency of all immunoglobulins and the absence of mature B cells, is caused by mutations in the gene encoding Bruton tyrosine kinase (BTK). Most patients have recurrent sinopulmonary infection. Infections usually occur in multiple locations across time, but single infection may be limited to one anatomic location. OBJECTIVES To report a case of atypical XLA with recurrent pyoderma and to observe the immunologic changes in the patient in 10 years. METHODS Immunologic investigations, skin wound culture, and molecular study with DNA sequencing were performed. RESULTS The patient was originally diagnosed as having common variable immunodeficiency disease because of the presence of circulating B cells (CD19+ B cells: 7%) at 11 years old. On further evaluation at the age of 20 years, flow cytometric analysis of lymphocytes showed only 0.4% B cells. The molecular study with DNA sequencing of the patient showed a point mutation in complementary DNA 1630 A>G(p.R544G) in the BTK gene, indicating that the patient has XLA. The mutation analysis of the BTK gene revealed a normal DNA sequence in the other family members. CONCLUSIONS This case is an important example of a possible presentation of XLA with a predominant skin manifestation, and it demonstrates that maintaining a high level of clinical suspicion is essential for the diagnosis of XLA in a child with recurrent pyoderma.

Abstract
The purpose of this study was to compare the safety and efficacy of cetirizine plus pseudoephedrine (C+P) with loratadine plus pseudoephedrine (L+P) in the treatment of perennial allergic rhinitis. This was a double blind, randomized, parallel trial with an active control. Subjects aged 12 to 70 years with perennial allergic rhinitis for at least 2 years were enrolled and randomized to receive either of the active study medications plus a placebo resembling the other, twice daily for 4 weeks. Nasal total symptom scale (NTSS) including sneezing, rhinorrhea, nasal itching and nasal stuffiness is evaluated by subjects daily and at baseline, 2 weeks, and 4 weeks by the investigator as efficacy measurement. A total of 51 eligible patients were enrolled and 45 patients completed the treatment course. Both groups had significant reductions in NTSS after 4 weeks of treatment as assessed by the subjects, but there was no significant difference between the two groups (mean +/- SD) reduction of 4.25 +/- 2.45 with C+P vs. 3.52 +/- 2.41 with L+P, p = 0.215. As assessed by the investigator, sneezing was significantly better at 2 weeks (-1.13 vs. -0.52, p = 0.028) and nasal congestion at 4 weeks (-1.71 vs. -1.19, p = 0.031) in subjects treated with C+P compared to those treated with L+P. There were 37 treatment-related adverse events (5 in 4 subjects in the C+P group and 32 in 16 subjects in the L+P group). It was concluded that both cetirizine plus pseudoephedrine and loratadine plus pseudoephedrine are efficacious for perennial allergic rhinitis in Taiwanese subjects. Relief of sneezing and nasal congestion may be marginally better with the cetirizine preparation, which also seemed to be slightly better tolerated, although the incidence of side effects did not differ significantly.

Abstract
IgE-mediated hypersensitivity to buckwheat is common in Korea, Japan, and some other Asian countries. However, buckwheat is not a common allergen in Taiwan. We report a woman with asthma who had anaphylactic shock, generalized urticaria, and an acute exacerbation of asthma five minutes after ingesting buckwheat. The patient underwent skin prick and Pharmacia CAP testing (Uppsala, Sweden) for specific IgE to buckwheat, white sesame and soybean as well as other common allergens in Taiwan including Dermatophagoides pteronyssinus (Dp), D. farinae (Df), cat and dog dander, cockroach, egg white, cow milk and codfish. The patient had a strongly positive skin prick test response to buckwheat and positive reactions to Dp and latex. Specific IgE results were class 6 for buckwheat, class 4 for Dp and Df, and class 2 for dog dander, wheat, sesame and soybean. Results of an open food challenge with white sesame and soybean were negative. Although buckwheat is a rare allergen in Taiwan, it can cause extremely serious reactions and should be considered in patients presenting with anaphylaxis after exposure to buckwheat.

Abstract
BACKGROUND X-linked hyper-immunoglobulin M (IgM) syndrome (XHIGM) is a rare immunodeficiency disease caused by mutations of the CD40 ligand gene. Patients are subject to recurrent infections and have normal or elevated levels of IgM but markedly decreased serum IgG. OBJECTIVE We describe molecular genetic studies and clinical manifestations in three generations of one family, as well as results of long-term treatment of 2 young men with the disorder. METHODS Of 37 living family members, mutational analysis of the CD40 ligand gene was performed in 36 members. Laboratory data for patients and carriers were reviewed. RESULTS Four male family members had died of unexplained causes. The 3 patients with XHIGM syndrome and the 5 carriers all had a novel mutation located at Tyr 169 Asn (T526A) in exon 5, the tumor necrosis factor domain of the CD40 ligand gene. In the 3 patients, CD40 ligand expression in activated CD4+ T cells was below 1%. In the carriers, about half of activated CD4+ cells expressed CD40 ligand. One carrier had malignant lymphoma. Long-term (>20 years) intravenous immunoglobulin therapy in 2 patients improved IgG levels but did not fully suppress the high levels of IgM, nor did it prevent late complications (bronchiectasis and sclerosing cholangitis). CONCLUSIONS Diagnosis of a genetic immunodeficiency, especially an X-linked disease such as XHIGM syndrome, should prompt a survey of the entire family.

Abstract
BACKGROUND Systemic anaphylaxis after the ingestion of mite-contaminated food has rarely been reported. OBJECTIVE To describe an 8-year-old boy in whom systemic anaphylaxis developed shortly after the ingestion of pancakes prepared with commercial pancake flour. METHODS The patient underwent skin prick testing for house dust mites and with uncontaminated and mite-contaminated pancake flour. Specific IgE for mites and the main ingredients of the pancake flour were also evaluated, with titers for Der p 1, Der f 1, and Blo t 5 quantitated using immunochemical methods. A sample of pancake flour was examined microscopically for mites. RESULTS The patient had positive skin prick test results to contaminated pancake flour extract (1 g/5 mL), Dermatophagoides pteronyssinus, and Dermatophagoides farinae but a negative skin test response to uncontaminated pancake flour. The patient's serum specific IgE analysis was positive for antibodies to dust and storage mite allergens. There was no response, however, to the main ingredients of the pancake mix. Microscopic examination of the pancake flour revealed the storage mite Blomia freemani. Using an immunochemical assay, we found that the contaminated flour contained 5.4 microg/g of the allergen Blo t 5 but no Der p 1 or Der f 1. CONCLUSIONS This patient's anaphylactic episode was the result of ingestion of the storage mite B. freemani. To our knowledge, this is the first reported systemic hypersensitivity reaction caused by this mite anywhere in the world.

Abstract
Inherited complement deficiencies are rare, particularly those associated with late components of the complement cascade. We report a 5-year-4-month-old Taiwanese boy with systemic meningococcal infection who had undetectable CH50 level of < 6 U/mL (normal, 32.6-39.8 U/mL). Levels of C3, C4, C5, C6 and C8 were normal, but C7 was undetectable (< 5.8 mg/dL; reference, 55-85 mg/dL). The patient's sister was also C7-deficient (CH50 < 6 U/mL, C7 < 5.8 mg/dL). His father's CH50 was 25.9 U/mL and C7 was 27.8 mg/dL. His mother's CH50 was 31.2 U/mL and C7 was 22.7 mg/dL. His parents thus both had a partial complement deficiency, indicating an autosomal codominant inheritance pattern. Awareness of the possibility of late complement deficiency is important as they comprise a small percentage of patients who present with disseminated meningococcal disease or other serious infections caused by encapsulated organisms.

Abstract
Trisomy 18 is the second most common autosomal trisomy in newborns. The birth prevalence of this disorder is approximately 1 in 3,000 to 1 in 8,000, and the life span of the majority of patients is less than 1 year. As information regarding outcome in trisomy 18 is rather fragmentary in the literature, this study is aimed at investigating the survival and natural history of trisomy 18. We also evaluated the survival age and management of trisomy 18 in two different periods, before and after the implementation of National Health Insurance (NHI) program. Thirty-nine cases of trisomy 18 were collected in Mackay Memorial Hospital in a 17-year period, from 1988 to 2004. Delivery data, survival age, management before and after the implementation of NHI program, structural defects, image findings and cytogenetic results were analyzed by medical and nurse's records. The diagnosis of trisomy 18 was based on the prenatal amniocentesis or postnatal chromosome analysis. Three patients had trisomy 18 mosaicism. Since cardiovascular and central nervous systems are the most common organ systems involved in this disorder, 31 patients received brain ultrasonography and heart ultrasonography for evaluation of their multiple anomalies after admission. All patients except one died in their first year due to severe malformations of the cardiovascular or central nervous systems. The median survival age was 6 days. We found a longer survival with female patients than with male patients (P < 0.05). Implementation of NHI program in the more recent decade of this study period was associated with longer survival of trisomy 18 (P < 0.05). The three most common structural defects were clenched hands (95%), rocker bottom feet (90%), and low set or malformed ears (90%). Low birth weight was present in 90%. By cardiac ultrasonography, the top four heart defects were ventricular septal defect (94%), patent ductus arteriosus (77%) and atrial septal defect (68%). However, ten cases (32%) had complex congenital heart defects. By brain ultrasonography, the most common brain lesion was cerebellar hypoplasia (32%), followed by brain edema (29%), enlarged cisterna magna (26%) and choroid plexus cysts (19%). Although most patients with trisomy 18 die within the first few weeks after birth, it is important to recognize that a small but notable percentage of these patients will survive the first year. When prenatal or postnatal decisions need to be made, the possibility of long-term survival should be included in any discussion to enable families to make the most appropriate decision.

Abstract
Bacille Calmette-Guerin (BCG) vaccination is used to prevent severe M. tuberculosis infection. It has been used in many countries for a long time. However, complications do occur, including localized abscesses, regional lymphadenitis and disseminated disease. The latter is often associated with underlying immunodeficiency. We report an 8-month-old male infant presenting with cough and fever who had had a generalized pigmented skin rash for one month. Skin biopsy revealed mycobacterial infection, but his response to treatment was poor and he had a persistent mild fever. Immunological studies revealed an IgG of 49 mg/dl, IgA 4 mg/dl, IgM 28 mg/dl, IgE < 1 mg/dl, CD3 1.1%, CD4 0.6%, CD8 0.6%, CD19 93.9%, CD57 1.1%, activated T cells 0.9%, and CH50 < 6.3%. These findings are compatible with the diagnosis of T(-)B(+)NK- severe combined immunodeficiency. Sequence analysis was performed and showed the presence of missense mutation in IL2Rgamma gene. An X-linked recessive inheritance pattern was proved by sequence analysis of his mother and grandmother. In order to identify the strain of the microorganism, we reviewed pathology of the skin biopsy which consisted of diffuse histiocytic infiltrate with poorly formed granulomas and no necrosis and used polymerase chain reaction (PCR) with the stain-positive clinical specimen and verify the organism found in the child's biopsy as M. bovis BCG strain. The diagnosis of disseminated BCG disease must be considered in any infant with cutaneous mycobacterial lesions, especially with atypical histologic findings. Such a patient's immunologic status should be evaluated and further family study is suggested. A high index of suspicion is needed to make a timely diagnosis, as early intervention with intensive treatment and bone marrow transplantation may be life-saving.

Abstract
BACKGROUND Hyper-IgM1 syndrome is a rare genetic primary immunodeficiency disease caused by mutations of the CD40 ligand gene. It is characterized by normal or elevated levels of IgM and markedly decreased serum IgG, IgA, and IgE levels. Patients with this syndrome often easily develop infections. During the past decade, it has become clear that enteroviral infections may also occur as a manifestation of hyper-IgM1 syndrome. OBJECTIVE To report a case of hyper-IgM1 syndrome in a 3-month-old boy who had interstitial pneumonia and intractable diarrhea. METHODS Chest radiography, bronchoscopy, immune studies, and open lung biopsy were performed. RESULTS Chest radiography revealed diffuse bilateral infiltrates. Immune studies revealed the following proportions of lymphocyte markers: CD3, 5,976/microL; CD4, 5,015/microL; CD8, 866/microL; CD19, 1,325/microL; CD16 + 56, 935/microL; and active T cells, 225/microL. The IgG level was 190 mg/dL; IgA, 2 mg/dL; IgM, 34 mg/dL; IgE, 1 IU/dL; and CH50, 23.8/mL. CD40L expression was less than 1%, and a Tyr 169 Asn (t526a) mutation in the exon 5 tumor necrosis factor domain of the CD40L gene was found. The patient was treated with intravenous immunoglobulin and had a dramatic improvement in symptoms. Open lung biopsy failed to demonstrate pneumocystis, and there was no evidence of cryptosporidium in the stool. However, coxsackievirus B4 was isolated by viral throat culture. CONCLUSION Interstitial pneumonia and diarrhea caused by coxsackievirus B4 may be a complication of hyper-IgM1 syndrome.

Abstract
Chlamydia trachomatis is one of the important causes of afebrile pneumonia in infants. The purpose of this study was to evaluate the demographic features, clinical manifestations, and outcome of C. trachomatis pneumonia patients seen during the past 10 years in one medical center. We reviewed the records on 30 patients with a diagnosis of C. trachomatis pneumonia. The diagnosis was based on characteristic clinical features and confirmed by culture, serologic testing, or polymerase chain reaction (PCR). Clinical features including age, sex, symptoms at the time of admission, laboratory data, and treatment were analyzed. Of the 30 patients (17 males and 13 females), 29 (96%) were less than 4 months old (range 10 days to 5 months). All patients had productive cough followed by tachypnea. Three patients (10%) presented with apnea. Four (13%) had conjunctivitis. Fever was present in only 3 (10%), of whom 2 also had concurrent respiratory syncytial virus infection. Peripheral eosinophilia (eosinophils > or = 400/mm3) was present in 14 (47%) patients. Hyperinflation was seen on chest x-ray in 15 patients. All infants were treated with erythromycin and responded well. The mean time to clinical improvement was 3.53 days after the start of treatment. The mean duration of hospitalization was 8.97 days (range, 3 to 17 days). No patients died. Pediatricians and general practitioners must have a high index of suspicion for chlamydial infection in afebrile infants presenting with tachypnea, peripheral eosinophilia, and hyperinflation on chest x- ray during the first four months of life.

Abstract
Wiskott-Aldrich syndrome (WAS) is an X-linked syndrome consisting of eczema, recurrent pyogenic infection, and thrombocytopenia with decreased platelet volume. Immunologic studies reveal normal immunoglobulin G (IgG), decreased IgM, elevated IgA and IgE levels, and decreased T-cell function. Patients with WAS often have increased susceptibility to lymphoproliferative disorders (LPDs). We report a 3-year-old boy who had persistent thrombocytopenia with bleeding, recurrent infections, and chronic eczema with frequent skin infections since birth. A blood smear revealed small platelets (50% of normal size). Immunologic studies showed normal IgG (1880 mg/dL), decreased IgM (76 mg/dL) and increased IgA (228 mg/dL) and IgE (14,282 IU/mL) levels. The relative proportions of immune cells were CD2 52.2%, CD3 41.1%, CD4 23.4%, CD8 16.8%, CD19 8.0%, CD57 7.7% and active T cells 14.6%. T-cell dysfunction was detected on the multitest for cell-mediated immunity. The WAS diagnosis was confirmed by mutation analysis which demonstrated a 4-base pair deletion in WAS protein gene exon 1. His thrombocytopenia was uncontrolled despite intravenous immunoglobulin infusions, so splenectomy was performed. The platelet count then rose to about 60,000 to 80,000/microL. However, about 2 weeks after splenectomy, he developed generalized lymphadenopathy and lymphoma was misdiagnosed based on lymph node biopsy at another hospital where he was admitted for urgent care. However, our analysis of his lymph node pathology led to the diagnosis of atypical LPD (ALPD). The lymphadenopathy regressed spontaneously 1 month later without chemotherapy. Early and correct diagnosis of WAS complicated with ALPD is important to avoid unnecessary chemotherapy.

X-linked hyper-immunoglobulin M (IgM) syndrome (XHIGM) is a rare genetic primary immunodeficiency disease caused by mutations of the CD40 ligand (CD40L) gene with normal or elevated levels of IgM and markedly decreased serum IgG, IgA, and IgE. Liver disease may occur as a clinical manifestation in XHIGM. This complication appears to increase with age. We report an 18-year-old male patient who had recurrent episodes of acalculous cholecystitis (AC) and sclerosing cholangitis (SC). The diagnosis of XHIGM was confirmed by the finding of CD40L expression < 1% of normal and a tyrosine 169 asparaginase (t526a) mutation in exon 5 (the tumor necrosis factor domain) of the CD40L gene. The patient had direct hyperbilirubinemia (direct bilirubin 5.5 mg/dL, total bilirubin 8.7 mg/dL), cholestasis (alkaline phosphatase 1133 U/L, gamma-glutamyl transferase 1019 U/L) and elevated transaminases (aspartate aminotransferase 70 U/L, alanine aminotransferase 101 U/L). Findings on abdominal ultrasound and abdominal computed tomography were compatible with AC. After the fourth episode of cholecystitis, cholecystectomy and liver biopsy were performed. Operative cholangiography revealed poor opacification of the hepatic duct and proximal common bile duct; the upstream intrahepatic bile ducts were not visualized. The biopsy specimen showed marked fibrosis of the portal areas. Enterococcus species was cultured from the bile. Children or adolescents with recurrent AC and SC should be evaluated for an underlying immunodeficiency syndrome such as XHIGM.

Abstract
DiGeorge syndrome is a primary immunodeficiency disease characterized by dysgenesis of the thymus and parathyroid glands, conotruncal cardiac anomalies, and other dysmorphic features. Although most patients have a common microscopic deletion in chromosome 22q11.2, marked clinical variability exists. A solitary median maxillary central incisor (SMMCI) is a rare dental anomaly which may be an isolated occurrence or associated with congenital nasal airway abnormalities or holoprosencephaly. We report a patient with DiGeorge syndrome who was diagnosed at nearly 1 month of age and was later found to have a solitary median central incisor. Initially, the patient presented with recurrent episodes of respiratory distress attributed to partial airway obstruction, one of the phenotypic features of SMMCI. A fluorescence in situ hybridization study showed a chromosome 22q11.2 deletion.

Abstract
X-linked hyper-IgM syndrome (XHIM) is a rare primary immunodeficiency disorder caused by mutations of the gene encoding the CD40 ligand (CD40L). It is characterized by recurrent infections with markedly decreased serum IgG, IgA and IgE levels but normal or elevated IgM levels. We report the clinical manifestations and complete immune studies in the first family with molecularly proven XHIM in Taiwan. A 5-month-old boy presented with rapidly progressive pneumonia which responded poorly to antibiotics. High levels of IgM and very low levels of IgG, IgA, and IgE were noted in his plasma specimen: IgM, 128 mg/dl; IgG, 18 mg/dl; IgA, 4 mg/dl); IgE, 1 IU/ml. Whole blood flow cytometry when he was 21 months old showed that only a small percentage (0.48%) of his in vitro-activated CD4+ T cells expressed CD40L. When he was 3 years old, repeated flow cytometry showed essentially the same result (0.4%), compared with his father's CD40L expression of over 85%. The patient's mother had moderately decreased CD40L expression (74.4%). Hyper-IgM syndrome was confirmed by CD40L mutation analysis in the boy, which revealed a Lys 96 stop (nucleotide A307T) in exon 2 of CD40L, with a truncated protein resulting in the loss of the entire TNF domain. His mother was a carrier and apparently the individual in whom the mutation originated. Eleven other family members, including the patient's father, sister, and grandmother, and the mother's sisters and their children, all had normal results on CD40L mutation analysis. The patient has remained without significant bacterial infection on a regimen of monthly IVIG infusion and oral trimethoprim-sulfamethoxazole for Pneumocystis carinii pneumonia (PCP) prophylaxis, although he has had recurrent oral ulcers and neutropenia. Bone marrow transplantation is planned.

Abstract
Neonatal lupus erythematosus is an uncommon passive autoimmune disease in which there is a transplacental passage of anti-Ro/SSA and/or anti-La/SSB maternal autoantibodies. Common clinical manifestations include cardiac disease, notably congenital heart block, cutaneous lupus lesions, hematologic disorders, and hepatobiliary disease. During the past decade, however, it has become clear that central nervous disease may also be a manifestation of neonatal lupus. We report a male neonate with the disease who had focal seizures in addition to cutaneous lupus, anemia, and thrombocytopenia. Brain ultrasound revealed normal ventricular size without a midline shift or intracranial or intraventricular hemorrhage. A brain CT showed generalized low density involving the periventricular and deep white matter. A sleep EEG revealed rare spikes axial to the right parietal lobe. The neonate had a high titer of antinuclear antibodies (1:640) with a speckled pattern, anti-Ro/SSA and anti-La/SSB antibodies, but no anti-dsDNA antibodies. He was given anti-convulsant drugs with dramatic improvement of his symptoms. One month later, a sleep EEG was normal, and he had no further seizures.

Abstract
The hyper-IgM syndrome (HIM) is a rare primary immunodeficiency disorder caused by defects in the CD40 ligand (CD40L)/CD40-signaling pathway. It is characterized by recurrent infections with markedly decreased IgG, IgA and IgE levels but normal or elevated serum IgM levels. A 5-month-old boy presented with rapidly progressive pneumonia which responded poorly to antibiotics. High levels of IgM and very low levels of IgG, IgE and IgA were noted in his plasma specimen (IgM, 128 mg/dl; IgG, 18 mg/dl; IgE, 1 IU/ml; IgA, 4 mg/dl). The relative proportions of immune cells were CD3 24.6%, CD4 10.3%, CD8 2.2%, CD19 30.2%, CD57 1.0% and active T cells 1.1%. After IVIG treatment, the pneumonia improved. Repeat assessment at the age of 15 months showed IgM decreased to the normal range (32 mg/dl). Whole blood flow cytometry assay for CD40L expression confirmed the diagnosis of hyper-lgM syndrome when he was 21 months old. Only a small percentage (0.48%) of the patient's in vitro activated CD4+ T cells expressed CD40L, compared with 33.54% from a healthy control. The patient's father, mother and sister all had a normal CD40L expression activation patterns (43.52%, 40.78%, 34.11%, respectively). On a regimen of monthly IVIG infusion and oral trimethoprim-sulfamethoxazole for Pneumocystis carinii pneumonia (PCP) prophylaxis, the patient has had no recurrent infections.

Abstract
Neonatal lupus erythematosus (NLE) is an uncommon passive autoimmune disease caused by transplacental passage of anti-Ro/SSA and/or anti-La/SSB or anti-U1RNP maternal autoantibodies. Common clinical manifestations include cutaneous lupus lesions, cardiac disease, notably congenital heart block, hematologic abnormalities, and hepatobiliary disease. The cutaneous lesions of NLE are usually transient, disappearing about six months after birth when maternal antibodies disappear from the infant's circulation. Persistent telangiectasia is a rare complication of NLE. We report a 3-year-old female who had cutaneous lupus with persistent facial telangiectasias over the frontal area. She was diagnosed with NLE at 2 months of age. Her findings then included cutaneous lupus, hemolytic anemia, a high titer of antinuclear antibodies (1: 640) with a speckled pattern, positive anti-Ro/SSA and anti-La/SSB antibodies, and absence of anti-dsDNA antibodies. Her mother had systemic lupus erythematosus with the presence of high titer of antinuclear antibodies (1: 1260) with a speckled pattern and positive anti-Ro/SSA and anti-La/SSB antibodies. The child's cutaneous lupus and hemolytic anemia disappeared at 6 months of age, but the telangiectasia persisted.

Abstract
Acute scrotum presenting as the only initial manifestation of Henoch-Schönlein purpura (HSP) is so unusual that the diagnosis can easily be missed. We report this condition in a 4-year-old boy admitted with bronchopneumonia. Bilateral painful scrotal swelling with ecchymosis occurred on the second day of hospitalization. Scrotal sonography was performed and a good blood supply was documented. Scrotal nuclear scanning was performed and was consistent with bilateral epididymoorchitis. Multiple purpuric lesions over the lower extremities and perineal region developed on the third day of hospitalization. Intermittent abdominal pain and knee pain developed thereafter. HSP was diagnosed and steroids were prescribed. The symptoms subsided gradually and no complication was noted. This case reminds us that an acute scrotum may be the only initial manifestation of HSP. Sonography and nuclear scanning can help rule out other diseases.

Abstract
Chronic granulomatous disease (CGD) is an inherited dysfunction of phagocytic cells secondary to a defect in the respiratory burst to kill catalase-positive microorganisms. This leads to recurrent life-threatening bacterial and fungal infections. We report a 1 year-10 month-old boy with X-linked CGD who was noted to have recurrent suppurative lymphadenitis since one and half month old. Failure to thrive, lymphadenitis and generalized skin lesions with multiple scar and dimples were found. Immunological data of patient, his mother and father were as follows: PMN phagocytosis (%): 98, 88, 92 (control, >80), PMN chemotaxis: 0.6, 1.0, 1.3 (control, >1.2), PMN bactericidal function test over a period of 2 hours (%): 28.1, 28.5, 84.8 (control, 82.1). PMN chemiluminescence (delta mV): 0.612, 364.1, 1131 (control, 614.1), H202 production (ug/mL): 1.6, 7.2, 16.8 (control, 14.1), NBT test: negative, mixed, positive (control, positive). His mother was a carrier. The patient expired with invasive salmonella infection before the availability of gamma-interferon prophylaxis.

Abstract
DiGeorge syndrome is a rare disorder characterized by a spectrum of thymic and parathyroid gland abnormalities, conotruncal cardiac defects, and typical facial dysmorphism. We report a male infant with partial DiGeorge syndrome characterized by truncus arteriosus, typical facial dysmorphism, hypocalcemia, lymphocytopenia with T-cell deficiency, and chromosome 22q11.2 deletion. Transient lymphocytopenia was noted for 5 days after birth and hypocalcemia was corrected with calcium gluconate administration. Surgical correction of the truncus arteriosus was performed at the age of 3 months. Unfortunately, the patient subsequently had an unwitnessed cardiac arrest, and despite resuscitation, died at the age of 4 months.

Neonatal lupus erythematosus is an uncommon passive autoimmune disease in which there is transplacental passage of anti-Ro/SSA and/or anti-La/SSB or anti-U1RNP maternal autoantibodies. Its common clinical manifestations include cardiac disease, notably congenital heart block, cutaneous lupus lesions, and hematologic problems. During the past decade, it has become clear that hepatobiliary disease may also occur as a manifestation of neonatal lupus erythematosus. We report a case of neonatal lupus erythematosus in a male infant who had lupus hepatitis with jaundice in addition to cutaneous lupus, anemia, and thrombocytopenia. Other diseases in the differential diagnosis of conjugated hyperbilirubinemia, including metabolic, infectious, and inherited anatomic conditions were all ruled out. The infant had a high titer of antinuclear antibodies (titer 1:640) with a speckled pattern, anti-Ro/SSA and anti-La/SSB antibodies, and no anti-dsDNA antibodies. Treatment with prednisolone (2 mg/kg/day) for 14 days resulted in dramatic improvement of the thrombocytopenia. Hemoglobin and bilirubin returned to normal 2 months later, and transaminases were normal by 10 months of age.
