ABSTRACT
We demonstrate coupling between the atomic spin- and orbital-angular momentum (OAM) of the atom's center-of-mass motion in a Bose-Einstein condensate (BEC). The coupling is induced by Raman-dressing lasers with a Laguerre-Gaussian beam and creates coreless vortices in an F=1 ^{87}Rb spinor BEC. We observe correlations between spin and OAM in the dressed state and characterize the spin texture; the result is in good agreement with the theory. In the presence of the Raman field, our dressed state is stable for 0.1 s or longer, and it decays due to collision-induced relaxation. As we turn off the Raman beams, the vortex cores in the bare spin |m_{F}=1⟩ and |-1⟩ split. These spin-OAM coupled systems with the Raman-dressing approach have great potential for exploring new topological textures and quantum states.
ABSTRACT
We demonstrate synthetic azimuthal gauge potentials for Bose-Einstein condensates from engineering atom-light couplings. The gauge potential is created by adiabatically loading the condensate into the lowest energy Raman-dressed state, achieving a coreless vortex state. The azimuthal gauge potentials act as effective rotations and are tunable by the Raman coupling and detuning. We characterize the spin textures of the dressed states, in agreements with the theory. The lowest energy dressed state is stable with a 4.5-s half-atom-number-fraction lifetime. In addition, we exploit the azimuthal gauge potential to demonstrate the Hess-Fairbank effect, the analogue of Meissner effect in superconductors. The atoms in the absolute ground state has a zero quasiangular momentum and transits into a polar-core vortex when the synthetic magnetic flux is tuned to exceed a critical value. Our demonstration serves as a paradigm to create topological excitations by tailoring atom-light interactions where both types of SO(3) vortices in the |⟨F[over â]⟩|=1 manifold, coreless vortices and polar-core vortices, are created in our experiment. The gauge field in the stationary Hamiltonian opens a path to investigating rotation properties of atomic superfluids under thermal equilibrium.

Acute otitis media (AOM) is the most common disease for which pediatricians prescribe antimicrobial agents. Middle ear fluid were collected from 243 children with AOM that failed to respond to a previous course of antimicrobial therapy and who had then received myringotomy from September 1997 through August 1999. Bacterial cultures were done and antimicrobial susceptibilities were analyzed. Streptococcus pneumoniae (21.8%) was the most common causative organism, followed by Haemophilus influenzae (10.2%), Staphylococcus aureus (7%), and Pseudomonas aeruginosa (1.8%), while Moraxella catarrhalis (0.7%) and group A beta-hemolytic streptococcus (0.2%) were rarely isolated. In patients whose condition failed to improve after a course of antibiotic treatment, drug resistance became a serious problem. Fourteen percent of the patients in this series had complications, which included recurrent AOM, persistent middle ear effusion necessitating ventilation tube insertion, hearing impairment, mastoiditis, meningitis, chronic otitis media, brain abscess, and sepsis. Possible risk factors such as young age, male sex, underlying diseases, and a culture of S. pneumoniae or H. influenzae were not significantly associated with an increased incidence of complications. More stringent diagnosis and the correct choice of antibiotic treatment combined with the introduction of potential virus and bacterial vaccines are promising ways to reduce the morbidity of AOM in children.

Intrauterine infections with varicella-zoster virus following maternal varicella in early pregnancy and resulting in congenital malformations are rare. Herein we report a child with congenital varicella syndrome characterized by low birth weight, cicatricial scarring, hypoplasia of both lower extremities with joint contracture, congenital hip dislocation, corneal opacity, atresia of the sigmoid colon and a rarely associated cloaca anomaly. The varicella IgG remained positive after she was seven months old. Her mother developed chickenpox at the 14th week of gestation. The purpose of this article is to raise pediatricians' index of suspicion for congenital varicella syndrome when an infant is born with multiple congenital malformations with an apparent history of maternal varicella infection.

Streptococcus pneumoniae infections can involve multiple organs and cause high mortality and morbidity. In this retrospective study, we reviewed patients with invasive pneumococcal infection in the pediatric department of a teaching hospital in Taipei. From 1984 to 1998, 81 children with invasive pneumococcal infection were hospitalized. Twenty-eight patients had meningitis, 27 had pneumonia with pleural effusion, 60 had sepsis, and 4 had arthritis. Thirty-eight patients had more than one site of infection. Most of our patients (81.7%) were below 5 years of age. Pneumococcal infections were more common from October to March. Eight patients had a history of trauma that correlated with the site of infection. Thirteen patients (16.0%) expired and 20 (24.7%) had severe sequelae. Multi-regression analysis found that meningitis and complications were independent variables that affected the outcome. The percentage of penicillin-resistant strains increased beginning in 1990 and accounted for about four-fifths of the infections in the final 2 years of the study. Since invasive pneumococcal infections in children may have a poor prognosis and penicillin-resistant strains have become increasingly common, early and adequate antibiotic therapy should be given as soon as possible.

Nineteen children with 21 episodes of acute mastoiditis were treated in our hospital from 1989 to 1998. The diagnosis was based on physical, radiologic, and surgical findings. The affected children were aged from 1 year old to 17 years old, with the peak incidence at 4 years old (23.8%). Postauricular pain (90.5%) and fever (81%) were the most common harbingers of incipient acute mastoiditis. Streptococcus pneumoniae (38.1%) was the most common organism isolated followed by Pseudomonas aeruginosa (23.8%). Underlying diseases such as leukemia and myeloid metaplasia were found in 38.6% of patients. All of the patients were initially treated with intravenous antibiotics during hospitalization. Six patients were managed with an adjunctive drainage procedure such as myringotomy or mastoidectomy. The most common complication of acute mastoiditis was hearing loss (31.6%); the second was meningitis (21.1%). Subperiosteal abscess was found in two patients and brain abscess in one. Although acute mastoiditis is an uncommon condition, early diagnosis and management are necessary to prevent more serious complications.

During the period from 1984 to 1997, 85 bacterial meningitis neonates with positive cerebrospinal fluid cultures were treated. The ages of these patients ranged from 1 to 28 days. The male to female ratio was 1.7 to 1. The most common causative agent was group B beta-hemolytic streptococci (GBS, 31.8%), followed by Escherichia coli (20%), Proteus mirabilis (7.1%), Enterobacter cloacae (5.9%), other streptococci excluding Streptococcus pneumoniae (5.9%), Chryseobacterium meningosepticum (5.9%), enterococci (4.7%), and Klebsiella pneumoniae (3.5%). Among the 85 patients treated, 51 (60%) were younger than 7 days old. Among them, dyspnea was the most common clinical manifestation. In contrast, fever and diarrhea were seen more frequently in neonates with late onset of disease (after seven days of age). Ampicillin and cefotaxime were the most commonly used antibiotics. The most frequently encountered complications were hydrocephalus and seizures. Since 1991, GBS has overtaken E. coli as the leading cause of neonatal bacterial meningitis. This was accompanied by a fall in the mortality rate, but a sustained high incidence of complications and sequelae. The results of this study highlight the importance of developing strategies to prevent group B streptococcal infection.

OBJECTIVES: To compare the accuracy of standard and hemocytometer white blood cell (WBC) counts and urinalyses for predicting urinary tract infection (UTI) in febrile infants. METHODS: Enrolled were 230 febrile infants < 12 months of age. All urine specimens were obtained by suprapubic bladder aspiration and microscopically analyzed by the standard urinalysis (UA) and by hemocytometer WBC counts simultaneously, and quantitative urine cultures were performed. Receiver-operating characteristic (ROC) curves were constructed for each method of UA. The optimal cutoff point of the UA test in predicting UTI was determined by ROC analysis. RESULTS: There were 37 positive urine cultures of at least 1,000 CFU/ml. Of these 37 patients, 9 females and 28 males, 1 had a positive blood culture (Escherichia coli). Thirty (81%) of the positive urine cultures had a bacterial colony count > or = 100,000 colony-forming units/ml, whereas the remaining had between 1,000 and 50,000 colony-forming units/ml. The area under the ROC curve for standard UA was 0.790 +/- 0.053, compared with 0.900 +/- 0.039 for hemocytometer WBC counts (P < 0.05). For hemocytometer WBC counts, the presence of < or =10 WBC/microl appeared to be the most useful cutoff point, yielding a high sensitivity (83.8%) and specificity (89.6%). Standard UA, with a cutoff point of 5 WBC/high power field, had a lower sensitivity (64.9%) and similar specificity (88.1%). The hemocytometer WBC counts showed significantly greater sensitivity and positive predictive value (83.8 and 60.8%, respectively) than the standard urinalysis (64.9 and 51.1%, respectively) (P < 0.05). The accuracy, specificity and likelihood ratio of hemocytometer WBC counts were also greater than that of standard UA (88.7, 89.6 and 8.08% vs. 84.3, 88.1 and 5.44%). CONCLUSION: Hemocytometer WBC counts provide more valid and precise prediction of UTI in febrile infants than standard UA. The presence of > or =10 WBC/microl in suprapubic aspiration specimens is the optimum cutoff value for identifying febrile infants for whom urine culture is warranted.

OBJECTIVE: To assess the usefulness of laboratory parameters, including peripheral white blood cell (WBC) count, C-reactive protein (CRP) concentration, erythrocyte sedimentation rate (ESR), and microscopic urinalysis (UA), for identifying febrile infants younger than 8 weeks of age at risk for urinary tract infection (UTI), and comparison of standard UA and hemocytometer WBC counts for predicting the presence of UTI. METHODS: A total of 162 febrile children <8 weeks of age were enrolled in this prospective study. All underwent clinical evaluation and laboratory investigation, including WBC count and differential; ESR; CRP; blood culture; a lumbar puncture for cell count and differential, glucose level, protein level, Gram stain, and culture; and a UA and urine culture. All urine specimens were obtained by suprapubic aspiration and microscopically analyzed with standard UA as well as with hemocytometer WBC counts. Quantitative urine cultures were performed. Sensitivity, specificity, accuracy, likelihood ratios, and receiver operating characteristic (ROC) curves were determined for each of the screening tests. RESULTS: There were 22 positive urine culture results of at least 100 colony-forming unit/mL. Eighteen of these 22 patients were males, and all were uncircumcised. There were significant differences for pyuria >/=5 WBCs/hpf, pyuria >/=10 WBC/microL, CRP >20 mg/L, and ESR >30 mm/hour between culture-positive and culture-negative groups (P <.05). The ROC area for hemocytometer WBC count, standard UA, peripheral WBC count, ESR, and CRP concentration were.909 +/-.045,.791 +/-.065,.544 +/-.074,. 787 +/-.060, and.822 +/-.036, respectively. The ROC curve analysis indicates that the CRP, ESR, and standard UA were powerful but imperfect tools with which to discriminate for UTI in potentially infected neonates. Hemocytometer WBC counts had the highest sensitivity, specificity, accuracy, and likelihood ratios for identifying very young infants with positive urine culture results. For all assessments, hemocytometer WBC counts were significantly different, compared with the standard urinalysis. ESR, CRP, and peripheral WBC counts were not helpful in identifying UTI in febrile infants. CONCLUSION: UTI had a prevalence of 13.6% in febrile infants <8 weeks of age. The CRP, ESR, and standard UA were imperfect tools in discriminating for UTI, and the sensitivity of these laboratory parameters was relatively low. Hemocytometer WBC count was a significantly better predictor of UTI in febrile infants.

In our clinical practice, we often encounter signs and symptoms of allergy, such as rhinitis and asthma, in patients with Tourette's syndrome (TS). Some of the allergic manifestations are similar to the oral tics or motor tics found in TS patients. To clarify the association between TS and allergy, we evaluated 72 consecutive patients with TS from 1 September 1996 through 31 August 1997. The diagnosis of TS was based on the Diagnostic and Statistical Manual of Mental Disorders diagnostic criteria. Sixty-five boys and 7 girls, 4 to 17 years old (9.4 +/- 3.1 yr) were evaluated using the Multiple Allergens Simultaneous Tests (MAST) for the detection of total and specific immunoglobulin. Forty-five patients had positive results, of whom 41 (56.9%) had clinical evidence of allergy. The prevalence of allergy in the local population as reported by The International Study of Asthma and Allergy in Childhood Taiwan Group (1994) was 44.3% (33.5% with allergic rhinitis and 10.8% with asthma). These subjects served as controls. Comparing the number of patients with clinical evidence of allergy in the MAST positive group (56.9%) of TS patients with the control group (44.3%), the difference was significant++ (p < 0.05). The prevalence of allergy in TS patients in our study was significantly higher than in the general population. TS had an association with allergy.

This study is to determine the incidence of visceral organ involvement in tuberous sclerosis (TS). We reviewed 30 cases of TS diagnosed between 1987 to 1997. There were 17 males and 13 females, ages ranged from one day old to 17 years old. Among the 30 cases, 25 patients had seizures and skin manifestations; 24 had cerebral tubercles; 10 had heart involvement (9 rhabdomyoma, 1 dilated cardiomyopathy); 4 had kidney involvement (3 polycystic kidney disease, 1 renal hamartoma); and 3 had retinal astrocytic hamartoma. Based on our study, the most common visceral organs involved were the heart and kidney. Among the ten patients with cardiac rhabdomyoma, six were less than 1 year old (mean age 1.6 +/- 2.2 years old). One newborn presented with a cardiac mass diagnosed by prenatal sonography and another newborn, noted to have tachycardia after birth, underwent surgical intervention due to impending heart failure. Four patients had kidney abnormalities; three were less than 5 years old (mean age 5.2 +/- 5.2 years). During this 10 year period, there was no mortality seen among patients with visceral organ involvement. We suggest that clinicians treating patients with TS should not overlook the visceral organs, especially heart and kidney, which, if involved can have significant morbidity.

Non-typhoid salmonella infection is not uncommon in immunocompetent patients in Taiwan. Bacterial factors may play an important role in the pathogenesis of such infections. In a previous study, Salmonella group D1 was found to have the tendency to cause bacteremia with a higher frequency than other serotypes. In the present study, we prospectively collected 94 Salmonella group D1 isolates for serotyping and molecular typing. Salmonella panama and Salmonella dublin seemed more invasive than other serotypes. Pulsed field gel electrophoresis was also done to characterize of Salmonella enteritidis and Salmonella dublin. PFGE type "a" of Salmonella dublin appeared to be more invasive than the other two PFGE types. All six Salmonella dublin isolates were Vi antigen negative. Further study using a larger number of isolates is needed to identify the tendency to invade blood stream of Salmonella dublin and Salmonella panama.

A 6-year-old girl with acute myelogenous leukemia (AML) developed fungal mandibular osteomyelitis during chemotherapy. Blastoschizomyces capitatus was recognized histologically by its yeast-like morphology and formation of annelloconidia, and was confirmed by culture. The fungal osteomyelitis of the mandible was treated successfully with prolonged antifungal medication, extensive surgical debridement and an oral care program, without interrupting leukemia chemotherapy. B. capitatus osteomyelitis of the mandible may occur during chemotherapy in AML patients with poor dental condition. Successful treatment can be achieved by careful management without interruption of antineoplastic chemotherapy.

Alice in Wonderland syndrome (AIWS) is characterized by visual hallucinations and bizarre perceptual distortions. Technetium-99m hexamethylpropyleneamine tomography (SPECT) brain scans were performed in four patients during the acute stage of AIWS. Two patients were demonstrated to have Epstein-Barr virus infections. One had abnormal (EEG) findings. The visual-evoked potential, cranial CT, and MRI findings were negative. The decreased cerebral perfusion areas in all patients were near the visual tract and visual cortex. All involved some regions of the temporal lobe. In most patients with AIWS, the EEG, CT, and MRI are unable to determine the precise pathologic areas. However, a SPECT brain scan may demonstrate abnormal perfusion areas and explain the clinical presentations.

Penicillin-resistant pneumococcal infections have been reported worldwide, but rarely reported in Taiwan. From 1990 to 1995, the rate of penicillin-resistant Streptococcus pneumoniae (PRSP) infections in our hospital increased from less than 10% during the first 2 years (1990-91) to 45% during the last 2 years (1994-95). From 1990 to 1995, twenty-four patients with systemic pneumococcal infections were diagnosed in the Department of Pediatrics at Mackay Memorial Hospital. Pneumococci were isolated from blood in 20 patients, cerebrospinal fluid in 12 patients, joint fluid in one patient and pleural effusion in one patient. Four patients had underlying diseases, including ileal atresia, Wiskott-Aldrich syndrome, congenital heart disease, and perilymph fistula. Of the 24 isolates of S. pneumoniae, 17 (70.8%) were intermediately penicillin resistant (minimum inhibitory concentrations between 0.1 and 1.0 microgram/mL), and 7 (29.2%) were highly resistant (minimum inhibitory concentrations > 1.0 microgram/ml). Fourteen patients recovered completely, two had minor sequelae, two had major sequelae, and six died. Four of the 12 patients with meningitis died. In this study, both the rate of PRSP as well as the mortality of patients with PRSP meningitis were high, as compared to previous reports. To reduce the mortality and morbidity of systemic pneumococcal infections, the oxacillin disc diffusion test is important in addition to appropriate antibiotic therapy.

During a period of twelve years (1984-1995), ninety-seven pediatric patients experienced 107 nosocomial fungal infections at Mackay Memorial Hospital. The nosocomial fungal infection rate in pediatric patients was lower than that of the hospital as whole, but it increased significantly. The average rate in the last three years (1993-1995) was 1.20 per thousand discharged patients, 10 times that of the first three years (1984-1986). Two-thirds of the patients were below one year of age. Half of the infections occurred in Intensive Care Units. The bloodstream was the most common site of infection (40.2%), followed by the urinary tract and skin. Important underlying diseases included malignancies, prematurity, and congenital anomalies. Common risk procedures included total parenteral nutrition (43.3%), endotracheal intubation (29.9%), central venous catheterization (25.8%), operation (14.4%). Near 90% of the patients had previously received antibiotics. Candida albicans was responsible for 58.1% of the infections. Thirty-three patients expired, of whom 18 died of the fungal infections. With the trend of increasing nosocomial fungal infections, physicians should be more alert to the possibility of such infections.

A term male neonate had an uncommon congenital vascular disorder of the skin covering the whole body and extremities. These skin lesions were characterized by mottling and persistent telangiectasia. A skin biopsy showed nevus vascularis reticularis which was recognized as cutis marmorata telangiectatica congenita. In addition to the cutaneous involvement, the patient also had fetal ascites, pleural effusion, patent ductus arteriosus, glaucoma, retinal detachment in the left eye, and telangiectasia in the right eye. Neonatal focal seizure developed and expired on the 34th day of life. The cerebral image studies suggested vascular anomalies with secondary cerebral parenchymal damage. Cutis marmorata telangiectatica congenita may be solitary but is frequently associated with other developmental defects. However, the specific findings of cerebral and ophthalmic lesions in our case were rather unusual.
