Phase I clinical trial of curcumin, a chemopreventive agent, in patients with high-risk or pre-malignant lesions.
Curcumin (diferuloylmethane), a yellow substance from the root of the plant Curcuma longa Linn., has been demonstrated to inhibit carcinogenesis of murine skin, stomach, intestine and liver. However, the toxicology, pharmacokinetics and biologically effective dose of curcumin in humans have not been reported. This prospective phase-I study evaluated these issues of curcumin in patients with one of the following five high-risk conditions: 1) recently resected urinary bladder cancer; 2) arsenic Bowen's disease of the skin; 3) uterine cervical intraepithelial neoplasm (CIN); 4) oral leucoplakia; and 5) intestinal metaplasia of the stomach. Curcumin was taken orally for 3 months. Biopsy of the lesion sites was done immediately before and 3 months after starting curcumin treament. The starting dose was 500 mg/day. If no toxicity > or = grade II was noted in at least 3 successive patients, the dose was then escalated to another level in the order of 1,000, 2,000, 4,000, 8,000, and 12,000 mg/day. The concentration of curcumin in serum and urine was determined by high pressure liquid chromatography (HPLC). A total of 25 patients were enrolled in this study. There was no treatment-related toxicity up to 8,000 mg/day. Beyond 8,000 mg/day, the bulky volume of the drug was unacceptable to the patients. The serum concentration of curcumin usually peaked at 1 to 2 hours after oral intake of crucumin and gradually declined within 12 hours. The average peak serum concentrations after taking 4,000 mg, 6,000 mg and 8,000 mg of curcumin were 0.51 +/- 0.11 microM, 0.63 +/- 0.06 microM and 1.77 +/- 1.87 microM, respectively. Urinary excretion of curcumin was undetectable. One of 4 patients with CIN and 1 of 7 patients with oral leucoplakia proceeded to develop frank malignancies in spite of curcumin treatment. In contrast, histologic improvement of precancerous lesions was seen in 1 out of 2 patients with recently resected bladder cancer, 2 out of 7 patients of oral leucoplakia, 1 out of 6 patients of intestinal metaplasia of the stomach, I out of 4 patients with CIN and 2 out of 6 patients with Bowen's disease. In conclusion, this study demonstrated that curcumin is not toxic to humans up to 8,000 mg/day when taken by mouth for 3 months. Our results also suggest a biologic effect of curcumin in the chemoprevention of cancer.

[Educational effects of a short-term diabetes camp for children].
A Diabetes camp provides children with fun and educational experience. Seventeen diabetic school children (12 boys and 5 girls) participated in a short-term diabetes camp from April 16 to 17, 1988. Their ages ranged from 8.5 to 13.2 years with an average of 11.3 +/- 1.5 (mean +/- SD) years. The duration of their diabetes varied from 0.05 to 5.3 years with an average of 2.7 +/- 3.3 years. The camp staff consisted of a pediatric endocrinologist, 3 nurses, 4 dietitians, 3 social workers, 4 assistant diabetes educators, and 2 counsellors who were specialized in music and recreational activities. The children's abilities in managing their diabetes were assessed by using a scoring system before and after the camping. Wilcoxon matched-pairs signed-rank tests with significance levels set at p < 0.05 (two-tailed) were conducted to determine whether there were any significant changes in the results from pre- and postcamp assessments. The children showed significant improvement in using glucose-monitoring devices, drawing insulin, injecting insulin, and choosing the right exchange of food with the p values of less than 0.05, 0.01, 0.01, and 0.01 respectively. We concluded that this short-term diabetes camp was educational for school children with diabetes. The campers improved their knowledge and skill in management of diabetes.

[Complications in the use of mechanical ventilator in newborns: one year's experience].
A retrospective study was undertaken of 175 patients (119 males, 56 females) admitted to the neonatal intensive care unit of Mackay Memorial Hospital during the period of July 1, 1985 to June 30, 1986 who received mechanical ventilation during their stay at the hospital. Upon reviewing the clinical histories of these patients, the complication rate of mechanical ventilation was 31.9%. The percentages of each complication were: pneumothorax 50.0%, pneumomediastinum 5.2%, pulmonary interstitial emphysema 1.7%, atelectasia 13.8%, pneumonia 13.8%, chronic lung disease 13.8%, nasopharyngeal infection 1.7%. Survival rate of these ventilated patients with or without complication was not significant statistically (69.2% vs 65.6%). However, with regard to the hospital course, cases with complication had a significantly longer duration of ventilator usage, hospital stay and oxygen usage than uncomplicated cases. In conclusion, experienced personnel are needed to supervise the use of mechanical ventilation in neonates, and a team of well-trained nurses working in the neonatal intensive care unit are essential to minimize complications.

[Abdominal pain in diabetic ketoacidosis: report of four cases].
Four cases of diabetic ketoacidosis presenting with abdominal pain are reported. Case 1: a 14-year-old boy suffered from sudden onset of mid-abdominal pain, then migrating to the right lower quadrant. Nausea and vomiting occurred subsequently. Appendectomy was performed under the impression of acute appendicitis in an outside surgical clinic. The patient became comatose the next day and then was transferred to our hospital. Diabetic ketoacidosis was diagnosed after the detection of hyperglycemia, glycosuria, and ketonuria on the day of admission. Unfortunately, he expired on the same day in spite of vigorous resuscitation. Case 2: a 9-year-old boy complained of abdominal pain for 10 days. There was no specific finding in the physical examination. Diabetic ketoacidosis was confirmed four days later when conscious disturbance, dehydration, and tachypnea were noticed. Case 3: a 10-year-old girl presented with a history of intermittent abdominal pain for one month. The character of the abdominal pain was nonspecific. Glycosuria was detected in a pediatric clinic. Diabetic ketoacidosis was confirmed after her referral to our hospital. Case 4: a 5-year-old girl suffered from acute abdominal pain for four hours. She was found to have tachypnea, lethargy, and ill-looking. Diabetic ketoacidosis was diagnosed after serial examinations. The abdominal pain in diabetic ketoacidosis may lead the pediatrician into diagnostic error. Therefore, when a child presented with non-specific abdominal pain, a routine urine sugar should be checked in order not to miss the possibility of diabetic ketoacidosis.

Periventricular leukomalacia in infancy: ultrasonic diagnosis and neurological outcome.
During the more than five years from January 1984 to June 1989, twenty-four patients with definite or probable cystic periventricular leukomalacia (PVL) were diagnosed by cranial ultrasonography at Mackay Memorial Hospital. The 24 patients were divided into two groups. Group A comprise two boys and four girls who received longitudinal sonographic follow-ups for leukomalacia. Of these six patients, five were premature and all suffered from severe perinatal insults. In each case, sequences of developmental cystic PVL were observed by serially scanning the brain. High echogenicity was discovered during the initial stages (2 to 7 days) in the periventricular area, and cystic formations were observed between the age of 18 and 60 days. Clinically, only one patient developed normally; four had severe motor dysfunction and poor motor development; and one was lost during follow-up, Group B was composed of 18 patients who visited the out-patient clinic for psychomotor retardation evaluation, and were found through ultrasound to have or possibly have cystic PVL formations at various stages. The clinical work-up revealed that 12 had spastic quadriplegia; 2 had hemiplegia; 3 had spastic displegia; and 1 case had hypotonic cerebral palsy. In infants, PVL is considered to be a much more reliable and important prognostic predictor than intraventricular hemorrhage. Consequently, it is crucial that physicians should screen patients at high risk for PVL, especially those with perinatal insults.

[Congenital hypothyroidism missed on newborn screening: report of two cases].
Two male term babies were born at Mackay Memorial Hospital; both were born without incident. Newborn screenings (including phenylketonuria, homocystinuria, galactosemia, congenital hypothyroidism and G-6-PD deficiency) were performed at the age of three days and judged to be normal. In the later neonatal period, case 1 gradually developed prolonged jaundice, poor feeding and poor weight gain. The rechecked thyroid stimulating hormone (TSH) level was 276.3 mU/l. Case 2 was admitted with seizures; the TSH level, rechecked by chance, showing 11.6 mU/l. Under the suspicion of congenital hypothyroidism, serum confirmation tests were performed and showed TSH 393.6 mU/l, 37.09 mU/l and T4 2.87 micrograms/dl, 4.59 micrograms/dl, respectively. The diagnosis was, thus, congenital hypothyroidism with delayed rise in TSH level. The conclusion is that, regardless of the result of newborn screening, a serum confirmation test (T4 & TSH level) should be done in any infant who is suspected to have congenital hypothyroidism.

Clinical observation of meconium peritonitis.
Twenty cases of meconium peritonitis were found between September 1980 and March 1988 at Mackay Memorial Hospital. The male to female ratio was 1.5 to 1. Six of the 20 cases involved premature babies. The great majority presented symptoms and signs before 5 days old, but one case was not diagnosed until 13 months of age. Polyhydramnios of the mother was found in six cases (30%). Abdominal distension was the universal symptom in all 20 cases. Hydrocele was noticed in 8 of the 12 male babies. In seven cases (35%) radiological examination showed abdominal calcifications. All patients underwent surgical intervention. Peritonitis was of cystic type in seven cases (35%); fibroadhesive in nine cases (45%); generalized in four cases (20%). Evident intestinal perforation was noted in 13 patients, and a mechanical obstructive lesion was found in 9 cases (45%) including intestinal diaphragm, atresia, volvulus, and Hirschsprung's disease. In only two patients (10%) was neither evident perforation nor obstructive lesion. The overall mortality rate was 30% (6/20), with no mortality after 1986 (0/6). The mortality seemed increased in those associated with perforation (4/13) and midgut volvulus (2/2) in particular, compared with non-perforation cases (1/7). It appears that early aggressive operation, and meticulous postoperative care, have contributed to the higher survival rate in recent years.

[Congenital cutaneous candidiasis: report of two cases].
Congenital cutaneous candidiasis is a very rare disease. We reported two newborn infants in whom generalized skin eruption was noted at birth, characteristics of erythematous papules and pustules. The eruption involved head, face, neck, trunk and extremities. Candida albicans was demonstrated on direct KOH smear, by surface fungal cultures and skin biopsy. The disease implies a congenital intrauterine infection and is different from neonatal candidiasis which manifests as thrush, diaper dermatitis. The route of infection is ascending in congenital cutaneous candidiasis. The skin eruption is usually noted at birth or within 12 hours after delivery as a diffuse erythematous maculopapula, with pustules or vesicles distributed over head, face, neck, trunk and extremities. There is no fever; other constitutional signs are lacking. No evidence of impaired immunological responsiveness has been noted in previous study. Clinical features, direct smear examination of specimen and appropriate cultures are useful in differentiating the lesions from other more common dermatoses of the neonatal period. Topical antifungal therapy is sufficient unless systemic candidiasis is present. Prognosis for congenital cutaneous candidiasis is good.

Apolipoproteins A-I and B in non-insulin-dependent diabetes mellitus.
In recent years apolipoproteins A-I and B examinations have been performed on patients with coronary artery disease as a better predictor of the severity of atherosclerosis. In the present study, 21 treated male and 22 treated female patients with non-insulin-dependent diabetes mellitus (NIDDM) were examined and compared with controls of the same sex, age and body mass (23 males, 21 females). Cholesterol, triglyceride, LDL-cholesterol in male and female patients with NIDDM were significantly higher than in male and female controls. HDL-cholesterol in male and female patients with NIDDM was not different from those of male and female controls. Apolipoproteins A-I and B in male and female patients with NIDDM were higher than in male and female controls. [Apolipoproteins A-I (g/L) male 1.40 +/- 0.21 vs 1.25 +/- 0.15, p less than 0.005; female 1.56 +/- 0.23 vs 1.42 +/- 0.24, p less than 0.025. Apolipoproteins B (g/L) male 1.29 +/- 0.30 vs 0.97 +/- 0.22, p less than 0.001; female 1.34 +/- 0.34 vs 0.98 +/- 0.35, p less than 0.001.] Discrepancy between the higher apolipoprotein A-I and the normal HDL-cholesterol in in NIDDM supports the theory of altered composition of HDL particles in diabetic patients. The controversy between the higher apolipoprotein A-I and the higher incidence of atherosclerosis in patients with NIDDM makes the clinical usefulness of this laboratory measurement doubtful in these patients.

Serum thyrotropin-binding inhibiting immunoglobulin and thyroperoxidase antibody in Graves' hyperthyroidism after 131I therapy.
Seventeen patients who received radioiodine (131I) therapy for Graves' hyperthyroidism had serial blood samples taken before therapy and after therapy for a period of at least 1 year. At 1 year post-therapy, six patients were hypothyroid. Seven patients were euthyroid, and four patients were hyperthyroid. Prior to isotope administration, 14 patients had detectable serum thyrotropin-binding inhibiting immunoglobulin (TBII) and 16 patients had detectable serum thyroperoxidase antibody (TPOAb). Three to 6 months after therapy, 11 of 14 TBII-positive patients demonstrated a marked increase (> 10%) in serum TBII activity. Four patients out of 11 developed hypothyroidism and six of the 11 developed euthyroidism. A decrease in TBII was observed in three patients who developed hyperthyroidism. In the three patients with undetectable TBII prior to therapy, two had high titers of TPOAb. Seven patients demonstrated a marked increase in TPOAb 3 to 6 months after therapy. Of these, four developed hypothyroidism and three developed euthyroidism, whereas three of the four patients who had a marked decrease in TPOAb developed hyperthyroidism. This study demonstrated that an increase in serum TBII and TPOAb activity 3 to 6 months after 131I therapy, may be useful in predicting which patients may develop euthyroidism or hypothyroidism after 1 year of 131I therapy.

The VATER association: analysis of forty six cases without karyotyping.
Forty-six patients with two or more features of the VATER association admitted to the Mackay Memorial Hospital from May, 1983 to Mar, 1992 were retrospectively enrolled in this study. We compared the incidence of major features with that reported in the literature. Imperforate anus, congenital heart disease, and renal anomalies were the three most common major features in our study. Thirteen patients died. Heart failure was the major cause of mortality. We noted many patients associated minor features, and among them there was a relatively high ratio of cleft lip, cleft palate, and hypospadius. The overall outcome and development were good among the survivals. We suggest that children who have any congenital anomaly included in the VATER association should get a careful examination and evaluation of their heart, genitourinary tract, limbs and vertebrae. Early correction if possible is indicated in such patients.

Urinary tract infection in infants less than 2 months of age.
Ninety-five infants, less than 2 months of age, diagnosed as urinary tract infections, from July 1984 to June 1991, were reviewed. Their urinary cultures, obtained either by suprapubic puncture or via catheterization, all had bacterial colony counts of over 10(5)/ml. In this survey, males predominated (91.6%). Fever and gastrointestinal problems were the two most prevalent signs. E. coli was the most common causative organism, and gentamicin was the most effective antibiotic. Vesicoureteral reflux (VUR), the most common anomaly, was found in one-third (25/76) of patients on voiding cystourethrography, with 20% being high grade (Gr. IV or Gr. V). Eleven cases (11%) had bacteremia, and one case had bacterial meningitis. Sixty-seven cases were followed up in our hospital and seven of them had second infections within a year of their first UTI. The mean period between episodes was less than two months. All these patients had urinary tract anomalies and received oral chemoprophylactic drugs for variable lengths of time. Five of the seven recurrences were caused by resistant bacilli. Continuous oral antibiotic prophylaxis and regular follow-up examinations were the rules of prevention for further infection and future renal impairment. These preventive methods are especially important in young infants with UTI.

Computerized Dysmorphology Database Mackay (CDDM): preliminary report.
A computerized dysmorphology database is useful for the pediatrician and geneticist in the task of diagnosing multiple malformation syndromes in children. We set up a new dysmorphology database "Computerized Dysmorphology Database Mackay (CDDM)" managed by the Clipper program. At present 278 disease entities with their clinical features and references are stored in the database. In this article, we report a practice analysis of ten dysmorphic patients by CDDM. A specific syndrome was accurately and rapidly diagnosed with the aid of CDDM in all ten cases. They serve as examples on how CDDM can be efficiently applied to obtain a short list of syndromes for differential diagnosis.

[Clinical study of infants with birth weight less than 1500 grams].
One hundred and seventy-seven infants of birth weight less than 1500 grams admitted to the neonatal intensive care unit of Mackay Memorial Hospital in 1987 were studied. The sex distribution, male to female ratio was 100:77, inborn 78 cases, outborn 99 cases. At one year follow-up, the mortality rate of these weighed between 500 gm and 799 gm was 100%, between 800 gm and 999 gm 54%, between 1000 gm and 1249 gm 17%, between 1250 gm and 1499 gm 19% respectively. The mortality rate of outborns was higher than that of inborns (X2 = 6.03, P < .05). The most common cause of mortality of these infants was intracranial hemorrhage, it accounts for 55% of the mortality. Seventy-three percent of the deceased cases expired during the first three hospitalization days. Of these 177 cases, 94 were put on respirator with IPPB initially, another 47 cases were on nasal CPAP. Only 36 cases didn't require respiratory therapy. Complications of the extreme prematurity and management including intraventricular hemorrhage, pulmonary hemorrhage, sepsis, pneumothorax, persistent pulmonary hypertension, disseminated intravascular coagulopathy, electrolyte imbalance, bronchopulmonary dysplasia and retinopathy of prematurity were discussed. In order to improve survival and reduce complications of these extreme prematurity, advanced monitoring system, early detection and prevention of intracranial hemorrhage, establishment of the transport system are essential.

Pulmonary artery sling with tracheo-bronchial stenosis: report of one case.
This patient is a 6-month-old female baby with intermittent symptoms of air-way obstruction for two months. The diagnostic examinations performed included: esophagogram, two-dimensional echocardiography, cardiac catheterization with selective right pulmonary arteriography, magnetic resonance imaging (MRI) and tracheo-bronchogram. The esophagogram revealed anterior indentation of the esophagus. The echocardiogram, cardiac catheterization and MRI all demonstrated anomalous origin of the left pulmonary artery from the right pulmonary artery instead of the main pulmonary artery. The tracheo-bronchogram showed long-segment stenosis of the lower portion of the trachea. A final diagnosis of pulmonary artery sling with tracheo-bronchial stenosis was made. Since the parents refused surgery, the baby expired after several episodes of cyanosis & cardiac arrest.
