Abstract
(1) Background: Intravenous thrombolysis following acute ischemic stroke (AIS) can reduce disability and increase the survival rate. We designed a functional recovery analysis by using semantic visualization to predict the recovery probability in AIS patients receiving intravenous thrombolysis; (2) Methods: We enrolled 131 AIS patients undergoing intravenous thrombolysis from 2011 to 2015 at the Medical Center in northern Taiwan. An additional 54 AIS patients were enrolled from another community hospital. A modified Rankin Score ≤2 after 3 months of follow-up was defined as favorable recovery. We used multivariable logistic regression with forward selection to construct a nomogram; (3) Results: The model included age and the National Institutes of Health Stroke Scale (NIHSS) score as immediate pretreatment parameters. A 5.23% increase in the functional recovery probability occurred for every 1-year reduction in age, and a 13.57% increase in the functional recovery probability occurred for every NIHSS score reduction. The sensitivity, specificity, and accuracy of the model in the validation dataset were 71.79%, 86.67%, and 75.93%, respectively, and the area under the receiver operating characteristic curve (AUC) was 0.867; (4) Conclusions: Semantic visualization-based functional recovery prediction models may help physicians assess the recovery probability before patients undergo emergency intravenous thrombolysis.

Abstract
(1) Background: The acute effects of ozone, cold temperature and particulate matter less than 2.5 μm (PM2.5) in size related to asthma attacks are well known worldwide. The adverse effects of ozone and cold temperature on asthma morbidity in Taiwan are still inconclusive. (2) Methods: This retrospective study included patients who had asthma emergency room visits (ERVs) from 1 January 2016 to 31 December 2019 in a regional hospital in Taiwan. The short-term negative effects were estimated using Distributed Lag Non-Linear Models (DLNMs) for the relative risks (RRs) of asthma ERVs associated with PM2.5, ozone and cold temperature exposures within 5 days. (3) Results: There was a significant association between a 10 ppm increase in PM2.5 exposure and asthma ERVs at a 2-day lag (RR 1.166, 95% confidence interval (C.I.): 1.051-1.294). There was a significant association between ozone and asthma ERVs at a 1-day lag (RR 1.179, 95% C.I.: 1.034-1.345). The ambient temperature in cold weather compared with the temperature of minimum asthma ERV showed an RR of 1.214, 95% C.I.: 1.009-1.252 at a 1-day lag. (4) Conclusions: This study provides evidence that short-term exposure to fine suspended particulates, ozone and inverse temperature is associated with asthma exacerbation.

Abstract
BACKGROUND Dementia is a common disease in aging populations. The treatment has mainly focused on memory decline prevention and behavior control. Nonpharmacological treatments, such as cognition training, physical exercise, and music therapy have been effective in slowing memory decline. Chinese calligraphy handwriting (CCH) through breath regulation and fine hand control involves high concentration levels, emotion regulation, and self-awareness. CCH is a mind and body activity that is culturally relevant to older Chinese adults. This study evaluated the beneficial effects of CCH on mild cognitive impairment. METHODS In 2018, we conducted 8 weeks of CCH training at the Tri-Service General Hospital. The participants were asked to copy a regular script. At the end of the course, they gave oral presentations and showed their work. Self-report questionnaires on emotion, memory, upper limb coordination, attention, and language were collected before and after training. RESULTS The five questionnaires showed significantly positive feelings after CCH training. The conditions of emotional stability, concentration, hand movement, memory, and speech improved. CONCLUSIONS CCH training stimulated the brain and improved cognition, psychological symptoms, and hand stability. It is inexpensive and worthwhile for elderly Chinese individuals with mild cognitive impairment to take time daily to practice calligraphy.

Abstract
Advanced therapies have improved outcomes and also resulted in a growing risk of long-term adverse health events. This study intends to estimate incidences of adverse health events and examine differences in adverse health events among childhood cancer survivors, and to understand the concerns of mothers after their child has completed cancer treatment. An explanatory sequential mixed-method was used. A total of 201 paediatric cancer survivors' mothers with mean age 43.6 years were recruited. Of the survivors, 12.4% experienced five or more adverse health events. The incidence of adverse health events of altered body image, fatigue and neurocognitive problems were 31.54%, 14.77% and 12.53% respectively. Among survivors, significant differences in adverse health events of pain, endocrine problems and altered body image issues were identified. Survivors receiving radiotherapy, bone marrow transplants or completing treatment after 6-10 years experienced significantly more adverse health events. Maintaining health was the greatest concern for mothers, and the qualitative reports of their concerns could be categorised: living in uncertainty, and keeping forward-looking. Childhood brain tumour survivors were identified as experiencing more adverse health events than other survivors. The need for healthcare teams to consider mothers' health concerns was highlighted.

Abstract
To improve treatment results for children with de novo acute myeloid leukemia (AML), we introduced a novel protocol, Taiwan Pediatric Oncology Group-AML-97A, for AML other than acute promyelocytic leukemia (APL), for which modified conventional protocols were used. From January 1, 1997, to December 31, 2002, 141 children younger than 17 years old with de novo AML were enrolled. In total, 117 patients with non-APL AML were treated with induction therapy of idarubicin and cytarabine (Ara-C), postremission therapy with high-dose Ara-C - containing regimens for four monthly courses, and moderate-dose therapy with idarubicin and Ara-C for four monthly courses. The first 19 patients with APL were treated with all-trans retinoic acid, idarubicin and Ara-C, with the remaining five patients receiving all-trans retinoic acid and idarubicin, followed by maintenance therapy for 2 years. Stem cell transplantation was performed in 29 patients in first remission with a similar outcome as chemotherapy alone. The remission rate in the AML-97A study was 90%, the 5-year survival 51 +/- 5.3% (s.e.) and the 5-year event-free survival 50 +/- 4.8%; for APL, these were 100%, 86 +/- 7.0, and 75 +/- 9.8%. For the whole group, the 5-year survival was 57 +/- 4.7% and the 5-year event-free survival 54 +/- 4.4%. The AML-97A regimen was well tolerated.

Abstract
BACKGROUND The long-term use of methamphetamine (MAMP) can result in psychosis but it is not clear why some individuals develop psychotic symptoms, while others use MAMP regularly over long periods and remain unscathed. We set out to characterize MAMP users and to examine the relationship of pre-morbid personality, pre-morbid social function and other psychiatric disorders to MAMP psychosis. METHOD Four hundred and forty-five amphetamine users were recruited from a psychiatric hospital and a detention centre in Taipei, and were assessed with the Diagnostic Interview for Genetic Studies (DIGS). Their parents were interviewed with the Premorbid Schizoid and Schizotypal Traits (PSST) and the Premorbid Social Adjustment (PSA) schedules. Pre-morbid characteristics and psychiatric co-morbidity were compared between the MAMP users with a lifetime diagnosis of MAMP psychosis and those without. RESULTS The MAMP users with psychosis presented a clinical picture which mimicked the positive symptoms of schizophrenia: 85% had auditory hallucinations; 71% persecutory delusions; 63% delusions of reference. Compared with their non-psychotic counterparts, these MAMP users were younger at first MAMP use, used larger amounts of MAMP, had a significantly higher mean PSST score, and higher rates of major depressive disorder, alcohol dependence and antisocial personality disorder. CONCLUSIONS Earlier and larger use of MAMP was associated with increased risk of psychosis. Our data are also compatible with the view that pre-morbid schizoid/schizotypal personality predisposes MAMP users to develop psychosis, and that the greater the personality vulnerability, the longer the psychosis will persist.

Abstract
Cytochrome P450 (CYP450) enzymes are essential for xenobiotic metabolism. Although CYP450s are found in many tissues, CYP2B1/2 are primarily expressed in the rat liver. The constitutive expression in vivo of CYP2B1/2 is low but it is induced in the presence of various drugs such as phenobarbital (PB). In this study, CYP2B1/2 activity in cultured hepatocytes was assessed in situ with the introduction of a fluorogenic substrate, pentoxyresorufin. The product of 7-pentoxyresorufin-O-dealkylation (PROD), which is catalyzed specifically by CYP2B1/2, was detected using confocal laser scanning microscopy (CLSM). Primary hepatocytes cultured as monolayers on collagen-coated surfaces exhibited background PROD activity and minimal PB inducibility after 4 days in culture. In contrast, rat hepatocytes organized in compacted aggregates, or spheroids, exhibited higher levels of PROD activity and retained their ability for PB induction. The results from the CLSM analysis were verified by RT-PCR and Western immunoblotting analysis. Furthermore, CLSM in conjunction with image processing techniques and three-dimensional reconstruction revealed the localization of enhanced PROD activity in the center of spheroids. The results support the use of CLSM as a powerful tool for investigating CYP2B1/2 activity in cultured rat hepatocytes.

Abstract
Non-Hodgkin's lymphoma usually involves the central nervous system by metastatic disease. Primary spinal epidural non-Hodgkin's lymphoma (PSENL) is a relatively rare cause of spinal cord compression. It mainly occurs in adults past the 4th or 5th decades. This entity is even rarer in children. The proper treatment modalities are controversial in adults with PSENL. Radiotherapy is the main strategy after surgery; the role of chemotherapy is uncertain. Therapeutic experience in childhood PSENL is extremely limited. We report a 10-year-old boy presenting with backache and bilateral lower leg weakness after minor trauma. Small non-cleaved cell non-Hodgkin's lymphoma of the epidural space was proven after subtotal tumor removal. Other investigations including computed tomography of the chest and abdomen, bone scan, gallium scan, bone marrow aspiration, and cerebrospinal fluid study were all negative for occult disease. The patient received combined therapy with irradiation and chemotherapy after surgery. Esophageal stricture resulting from radiotherapy developed during treatment and colon interposition was performed. He has remained disease free 42 months after the diagnosis with normal functional status.

Abstract
OBJECTIVE Although Epstein-Barr virus (EBV) is known to cause immune thrombocytopenic purpura (ITP), the epidemiology of this pathogen in children with ITP is not known. In the present study, the clinicoepidemiology and laboratory characteristics of EBV-associated ITP in childhood were analysed retrospectively. METHODS The study cohort consisted of 108 children in whom ITP was diagnosed between 1990 and 1998. Patients were divided into EBV or non-EBV groups according to their serological status at diagnosis. RESULTS Thirty-five (32.4%) of 108 children had ITP associated with acute EBV infection. The clinical manifestations and laboratory data were similar in children with and without acute EBV. Responses to various modalities of therapy were analysed. The average time to achieve complete remission (platelet count > or =150 x 10(9)/L) in EBV and non-EBV groups was 26 and 16 days, respectively. CONCLUSIONS The incidence of childhood ITP associated with acute EBV infection is relatively high in Taiwan. Patients with EBV-associated ITP tended to resolve more slowly than those without EBV infection.

Abstract
A nation-wide chemotherapeutic trial for childhood non-Hodgkin's lymphoma (NHL) was conducted by the Taiwan Pediatric Oncology Group (TPOG). Four TPOG-NHL92 protocols based on stage and histology were activated in 1992: TPOG-92LD (treatment duration: 8 months) was used for localized (stages I/II) NHL with any histology, 92LB (2 years), 92SNC (5 months), and 92LC (1 year) for advanced (stages III/IV) lymphoblastic (LB), small non-cleaved cell (SNC), and large cell (LC) lymphoma, respectively. From January 1992 through June 1998, 200 children with newly diagnosed NHL from 13 member hospitals of TPOG were enrolled. There were 140 boys and 60 girls. Their ages at diagnosis ranged from 2.4 months to 18.3 years with a median of 8.2 years. There were 54 (27.3%) patients with LB, 94 (47.5%) with SNC including B-cell acute lymphoblastic leukemia (B-ALL), and 50 (25.2%) with LC. Stages I, II, III, and IV (including B-ALL) of the disease comprised 5%, 10%, 43%, and 42% of cases, respectively. There were 176 patients eligible for evaluation of treatment results. The remission rate of induction was 82.4%, induction failed in 22 (12.5%) patients, and nine patients died during induction. As of August 31, 1999, 26 patients relapsed, six died during remission, one patient developed secondary acute myelomonocytic leukemia, and 105 patients remained in continuous remission with a median remission duration of 49 months. The event-free survival (EFS) at 7 years was 63.5%, 61.5% and 65% for LB, SNC, and LC groups (P = 0.8298). The 7-year EFS for stages I/II, III, and IV of the disease was 73%, 68.9%, and 50.3% (P = 0.0212), respectively. We concluded that following the strategy of stratification of therapy, only disease stages had prognostic significance in this study. More efforts are needed to improve our treatment results.

Abstract
Transvestic fetishism is a paraphilia marked by recurrent, intense sexually arousing fantasies, sexual urges, or behavior involving cross-dressing, in a heterosexual male. There are many explanations of the pathogenesis, but none are conclusive. Different treatments have been applied, but they generally remain obscure and disappointing. Transvestic fetishists rarely seek psychotherapy, because of their dynamic balance between perversion and intrapsychic disintegration. There are few studies, either qualitative or quantitative, associated with transvestic fetishism in Taiwan. This case report describes an adolescent transvestic fetishist who underwent a brief course of psychotherapy in the outpatient department of a psychiatric center in Taipei. After consultation for one year, he still maintained his deviant sexual behavior but also developed more severe moral anxiety. He was then referred for psychotherapy. Cognitive-behavioral and psychodynamic theories associated with transvestic fetishism were reviewed and applied in both understanding and treating this client. Some temporal effectiveness was achieved with combined cognitive-behavioral and dynamic-oriented supportive psychotherapy. After 18 sessions of psychotherapy over more than 4 months, the client was able to stop his perverse behavior and have fewer sexually arousing fantasies. The prognosis of transvestic fetishism is generally supposed to be pessimistic and have a high rate of recurrence. Some propose that adolescents have a better outcome after treatment. This case report reveals the possibility of change for a transvestic fetishist. However, the long-term effects of the brief course of psychotherapy require further evaluation in the future.

Abstract
Primary rat hepatocytes can self-assemble to form multicellular spheroids when plated onto Primaria petri dishes or suspended in stirred vessels. These spheroids exhibit prolonged viability, enhanced liver-specific functions and differentiated ultrastructure compared to monolayer cultures. Upon transfer to collagen coated surface, or upon the addition of fetal bovine serum (FBS) to the culture, these spheroids began to disassemble and spread on the surface. The dynamics of cytochrome P450 CYP1A1/2 activity in the course of spheroid disassembly was examined in situ by detection of the fluorescent product, resorufin, of ethoxyresorufin O-dealkylation. Optical sectioning of the disassembling spheroids by confocal microscopy demonstrated that hepatocytes that reverted to monolayer exhibited markedly lower CYP1A1/2 activity than those that remained in a multilayered structure. This occurred whether the disassembly was caused by incubation with FBS-containing medium or by cultivation on a collagen-coated surface. When spheroids were cultured on the surface of agar, the disassembly process was retarded even in the presence of FBS. However, even in those intact spheroids, the exposure to FBS markedly decreased CYP1A1/2 activity. The decreased CYP1A1/2 activity was correlated to a diminished smooth endoplasmic reticulum as seen in the transmission electron micrograph. The results clearly demonstrate that the disassembly of hepatocyte spheroids led to decreased CYP1A1/2 activity. Furthermore, FBS contained a factor that caused CYP1A1/2 to decrease even in intact spheroids.

Abstract
Idiopathic thrombocytopenic purpura (ITP) preceding malignant lymphoma is a rare condition. Most cases occur simultaneously with lymphoma or after it has been diagnosed. The case of a child with idiopathic thrombocytopenic purpura recovered after prednisolone treatment, but lymphoma developed four months later. The pathogenesis for idiopathic thrombocytopenic purpura evolving into malignant lymphoma is still unknown and further study is necessary.

Abstract
A case in which inflammatory pseudotumor of the liver (IPTL) seemed to complicate severe congenital neutropenia (Kostmann's disease) is reported. IPTL is a rare entity, especially in childhood. The exact etiology of this lesion is unknown, but it is generally regarded as a benign, reactive inflammatory condition. Based on 15 reported pediatric cases in the literature, the causes, diagnosis, and treatment of IPTL are discussed.

Abstract
We report an extremely rare case of Ewing's sarcoma (ES) of the humerus in a Chinese neonate. Plain radiography and magnetic resonance imaging showed extensive neoplastic involvement of the humeral diaphysis and adjacent soft tissues, confirmed on histology and immunohistochemistry as being due to ES. This is the first report of congenital ES in a long bone. Since ultrasound at 20 weeks gestation showed a normal fetal skeleton, the ES may have begun to develop in the late middle or third trimester.

Abstract
Two patients were admitted to our hospital with the diagnosis of psychogenic vomiting of more than 9 months' duration. Both were treated with a combination of pharmacotherapy, relaxation training, cognitive therapy and supportive psychotherapy. Behavioral therapy and verbal catharsis were also used in one of the cases involving bereavement. The intervention was not directly aimed at the vomiting, but at the aspects of the patients' stress and emotional problems. Change in condition was assessed on basis of the frequency of vomiting and the severity of anxiety and depression. Vomiting was found to be positively related to anxiety but not to depression. These 2 patients improved to the extent that the disturbance caused by vomiting was significantly reduced, and the reduction was closely related to the severity of anxiety. Both were also found to have similar personality traits and family types, which have been reported to be related to psychogenic vomiting. We review the characteristics of psychogenic vomiting and relate some important considerations for treating Chinese psychogenic vomiting cases.

Abstract
Lipoblastomatous lesions are mesenchymal tumors of embryonal white fat and are classified into two forms: a superficial, well-defined mass (lipoblastoma) or a deep, infiltrative lesion (lipoblastomatosis). We report an unique case of mediastinal lipoblastoma in a 17-month-old boy which harbored a dual nature and exhibited the characteristics of both forms, a large well-encapsulated intrathoracic main tumor with focal infiltrative features at the thoracic inlet and transforaminal intraspinal extension forming a long-segment extradural mass. In addition to specific signal characterization of a fatty mediastinal mass with intratumoral streaks and whorls corresponding to the fibrovascular network, magnetic resonance (MR) imaging offered clear demonstration of the chest wall, lower neck and intraspinal extension, which was important for preoperative planning.

Abstract
Spleen rupture has been a rare but feared complication in patients with infectious mononucleosis. There have been many cases reported during the last decade. However, it has rarely been mentioned among the young infant group. Here, we present a case of an infant, two months of age, who suffered from spleen rupture due to infectious mononucleosis, and was latter cured by himself under conservative treatment.

Abstract
Two children with acute lymphoblastic leukemia presenting with cellulitis and sepsis are described. Both presented as having hemophagocytic syndrome with the manifestations of prolonged fever, jaundice, pancytopenia, coagulopathy and histiocytic proliferation with hemophagocytosis in their bone marrows. It is similar to the virus-associated hemophagocytic syndrome (VAHS), except for the absences of lymphadenopathy, skin rash and hepatosplenomegaly. Concomitant virus infections were excluded in these two cases. Both patients' conditions improved after appropriate antibiotics and intravenous immunoglobulin therapy. The prognosis seemed better in bacteria-associated hemophagocytic syndrome (BAHS) than in VAHS even in immunocompromised patients.

Abstract
Chest radiography, CT, and MR imaging were performed in a 3-year-old girl who had posterior mediastinal fibromatosis with transforaminal intraspinal and chest wall extension. Chest radiographs and CT scans showed a slow-growing, noncalcified but locally aggressive left paravertebral mass. The mass was slightly hyperintense relative to muscle on both T1-weighted and fast spin-echo T2-weighted MR images.

Abstract
From 1991 to 1995, we reviewed the medical records of 200 pediatric patients with systemic malignancies to study the occurrence of neurologic complications and their treatment. A total of 25 patients with neurologic complications were found. Complications included intracranial metastasis (one patient), intraspinal metastasis (one), spinal epidural compressions (three), leptomeningeal metastases (six), metabolic encephalopathy (10), opportunistic infection (one), cerebrovascular disorders (three), treatment complications (six) and paraneoplastic syndromes (two). Ten patients had seizures. One patient with acute lymphoblastic leukemia (ALL) had the unusual complication of cytomegalovirus retinitis and glaucoma. Seven patients had neurologic features at presentation. ALL was the most common malignancy (56%) and neuroblastoma (20%) was the second. Neurologic deficits are frequently seen in pediatric patients with systemic malignancies and can, in fact, be the presenting signs. Early diagnosis and treatment is important to prevent further neurologic disability.

Abstract
Phase diagrams containing the microemulsion region were constructed for pseudo-ternary systems composed for polyglycerol fatty acid ester/cosurfactant/Captex 300/water. It was found necessary to add ethanol, 1-propanol, 1-butanol as cosurfactant to produce microemulsions. The results also demonstrated microemulsions were only able to form when employing polyglycerol fatty acid esters with hydrophile-lipophile balances (HLBs) between 8 and 13, such as MO500, MO750, SO750, and ML310. Most microemulsions were determined to be Winsor type IV by dilution and dye solubility tests. Microemulsions stored at ambient temperature maintained constant viscosity, indicating that the system was thermodynamically stable for long periods. Further, several microemulsion formulations were demonstrated to be promising for oral delivery of insulin based on the results of stability tests and acid-protection efficiency.

Abstract
Rhabdomyosarcoma, a common soft tissue sarcoma in children, is rarely reported. The head and neck are the most common sites of occurrence. A case of embryonal rhabdomyosarcoma of the nasopharynx is presented. The patient, a five-year-old boy, presented with a two-monthly history of epistaxis. Ear-Nose-Throat examination revealed a mass at the hard palate. Head and neck MRI showed a nasopharyngeal mass with invasion to the skull base, and intracranial extention. Histological examination of the mass revealed embryonal rhabdomyosarcoma. A combination chemotherapy and intrathecal medication was administered. This was followed by radiotherapy to the tumor site with 2 cm free margins. A good tumor response was found.
