Disseminated Mycobacterium avium complex (MAC) infection can occur in immunocompromised patients, and rarely in immunocompetent subjects. Due to the extensive distribution of the disease, clinical presentation of disseminated MAC may mimic malignancies, and thorough examinations are required in order to make accurate diagnosis. We report a case of disseminated Mycobacterium intracellulare disease in an immunocompetent patient, which involved the lung, lymph nodes, spleen, and multiple bones. F-18 fluorodeoxyglucose positron-emission tomography imaging showed multiple hypermetabolic lesions, which are suggestive of typical hematogenous metastasis. However, there was no evidence of malignancy in serial biopsies, and M. intracellulare was repeatedly cultured from respiratory specimens and bones. Herein, we should know that disseminated infection can occur in the immunocompetent subjects, and it can mimic malignancies.

OBJECTIVES: Bisphenol A diglycidyl ether (BADGE) is the major component in commercial liquid epoxy resins, which are manufactured by co-reacting bisphenol A with epichlorohydrin. This study was performed to show the developmental effects of prenatal and postnatal exposures to BADGE in male rat offspring. METHODS: Mated female rats were divided into four groups, each containing 12 rats. The dosing solutions were prepared by thoroughly mixing BADGE in corn oil at the 0, 375, 1500 and 3000 mg/kg/day concentrations. Mated females were dosed once daily by oral gavage on gestation day (GD) 6 - 20 and postnatal day (PND) 0 - 21. Pregnant female dams were observed general symptoms and body weight. Also, male pups were observed the general symptoms, body weight, developmental parameters (e.g. anogenital distance, pina detachment, incisor eruption, nipple retention, eye opening, testis descent), organ pathologic changes and hormone levels of plasma. RESULTS: Pregnant rats treated with BADGE died at a rate of about 70% in the 1500 mg/kg/day group and all rats treated with 3000 mg/kg/day died. Body weight, for male pups treated with doses of 375 mg/kg/day, was significantly lower than in the control group at PND 42, 56, and 63 (p<0.05). Evaluation of body characteristics including; separation of auricle, eruption of incisor, separation of eyelid, nipple retention, descent of testis, and separation of the prepuce in the BADGE treated group showed no difference in comparisons with the control group. AGD and adjusted AGD (mm/kg) for general developmental items in BADGE 375 mg/kg/day treated pups tended to be longer than in controls, however, these differences were not statistically significant. Relative weights of adrenal gland, lung (p<0.05), brain, epididymis, prostate, and testis (p<0.01) were heavier than in control in measures at PND 9 weeks. There were no significant changes in comparisons of histological findings of these organs. Loss of spermatids was observed in the seminiferous tubule at PND 9 weeks, but no weight changes were observed. The plasma estrogen levels were similar in the control and treatment groups at PND 3, 6 and 9 weeks. The plasma testosterone levels in the control group tended to increase with age. However, in the BADGE 375 mg/kg/day treated male pups it did not tend to increase. CONCLUSIONS: These findings suggest that BADGE is a chemical that has developmental effects consistent with it being an endocrine disruptor.

Symptomatic primary heart tumors are rare in newborn. Cardiac rhabdomyoma is the most common lesion of the primary heart tumors and over half of them are related to kthe tuberous s clerosis. We described a case of cardiac rhabdomyoma, in a 2 day-old female newborn who presented with dyspnea and cyanosis. A 2D Echocardiogram demonstrated two masses; one is in the rt. ventricle and another is in the interventricular septum. Additional cardiac masses and cerebral tubers and subependymal giant cell astrocytoma were found at autopsy.

A synophthalmia, another form of cyclopia, in which the element of the two eyes are partially fused to form an apparently single eye in the middle of the forehead. The synophthalmia is a result of complex, neural plate misdevelopment syndrome involving the eye, brain, skull and face. It is well known that synophthalmia is due to heterogenous causes, most of which chromosomal imbalances. We experienced a case of synophthalmia associated with proboscis, alobar holoprosencephaly and chromosomal anomaly 46, XX, -15,t (15 q, 21 q). Diagnosis was confirmed by brain MRI and autopsy, The patient died about 20 hours of age and autopsy was done. A brief review of the literatures was also presented.

The unilateral megalencephaly is a rare brain malformation characterized by cerebral asymmetry and cortical dysplasia caused by faulty migration of the subependymal neuroblasts. We experienced a case of unilateral megalencephaly in a two day-old male with the chief complaint of asymmetric head appearance. Large left hemisphere with agyria, pachygyria, dilatation of lateral ventricle, and the thick cortex of the ipsilateral hemisphere were showed in brain MRL, Clinical findings in this case were intractable seizure, hemiparesis, and psychomotor retardation. A review of literatures was also presented briefly.

One hundred eighty infants with oxygen therapy who were under 2,500gm birth weight or under 37 weeks of gestational age, were examined between January 1990 and November 1992. We performed clnical analysis and results were as follows. 1) Fifty six infants (31.1%) were diagnosed as retinopathy of prematurity. 2) The first examination was performed at 2.5 weeks of life on average, and the retinopathy of prematurity was diagnosed at 3.8 weeks on average. 3) The incidence of retinopathy of prematurity was highly associated with low birth weight (< or =1,890 gm), low gestational age ( < or =33.1 weeks), and high oxygen concentration with long duration (FiO2> or =0.4 over 1 week)(P<0.005). 4) Other associated risk factors were idiopathic respiratory distress syndrome, anemia, neonatal hypoxia and sepsis.
