Adenocarcinoma*

The concurrence of typical carcinoid admixed with adenocarcinoma of the gastrointestinal tract is a well known but unusual phenomenom that has been reported in the esophagus, stomach, gall bladder, colon and appendix. The amine precursor uptake and decarboxylation (APUD) concept included the idea that neuroendocrine cells of the gastrointestinal tract were dervied from the neural crest by a process of migration during embryogenesis. However the intimate admixture of cells which have morphologic and immunocytochemical properties of both carcinoid tumors and adenocarcinoma suggests that these tumors are derived from a multipotential stem cell showing bidirectional differentiation rather than from unrelated cell lines. The term composite carcinoma-carcinoid tumor is therefore an appropriate designation for these neoplasms. We report a case of composite carcinoma-carcinoid tumor of the stomach in a 38 year-old female with brief review of literature.

Management of patients with unstable fracture or fracture-dislocation of thoraco-lumbar spine continues to be controversial. One area of disagreement involves spinal fusion with internal fixation for prevention of later spinal instability. Intemal fixation of the spine without fusion has been advocated in the treatment of the unstable thoraco-lumbar fracture or dislocation. During the period of January 1981 to March 1984, thirty-two patients underwent fixation by Harrington distraction rod without fusion for the treatment of thoraco-lumbar fractures. Eight cases among them had second operation for the removal of the Harrington rods in 13.4months after Harrington rod fixation and were followed up clinically and radiolagically for 1 year at the Department of Orthopaedic Surgery, St. Mary's Hospital, Catholic Medical College and Center. The rationales for this procedure were to minimize the number of permanently stabilized segments and to provide more spinal mobility. We have expected that spontaneous fusion of vertebral body occur by the prolonged immobilization with Hamngton distraction rods. After the Harrington rods, the average conection rate of kyphotic angle was 41.8% and average correction rate of height of collapsed vertebral body or displacement of vertebral body was 42.3% at one year follow up. Instrumentations in eight patient were removed at 13.4 months after the initial surgery and the patients were followed up for one year. At the time of removal of instrumentation, unilateral partial facetectomy was done for histologic examination of the facet joint which is above the lower Harrington hook in four patients. The average correction rate of kyphotic angle was 37.5% and the average correction rate of height of collapsed or displaced vertebral body was 40.6% at one year after the removal of H-rods. The range of spine motions were incresed gradually. But histologic findings of the immobilized facet joint revealed fibrillation, fissures, thinning of the normal cartilagenous surface, decreased cartilagenous cellularity, and vascular tidemark invasion which are characteristics of osteoarthritis. Through this study, we obtained following conclusions: 1. Immediate Harrington distraction rodding was effective for the anatomic reduction of the collapsed vertebral body. And it provided immediate spinal stability, and spontaneous fusion of vertebral body. 2. Prolonged immobilization of the spine by Harrington rods is believed to have deleterious effect on articular cartilage of the immobilized facet joint as the degenerative changes of the cartilage of the facet joint was consistently found in this study. And it was regarded as a predisposing factors in the development of symptomatic arthritis of the spine. 3. If a fractured and collapsed vertebral body can be reduced by Harrington distraction rods, a spontaneous fusion of vertebral body occur. Harrington rodding without fusion could be one of the useful surgeries for management of the fractures and fracture-dislocation of the spine.

To investigate relationship between alpha1-acrenoceptors and nicardipine, an 1,4-dihydropyridine calcium antagonist, effects of nicardipine, on phenylephrinne(PE)-induced vasoconstriction in isolated arterial rings and pressor response of rabbits were observed. In normal physiological salt solution(NPSS), 35mM KCI produced persistent contractions of thoracic aorta and carotid artery and the contractions were dose-dependently inhoboted by cumulative admini-stration of nicardipine in the range of doses from 10(-10)M to 10(-4)M, IC50s of nicardipine in the thoracic aorta and carotid artery were 3.3x10(-7)M and 4.6x10(-7)M, respectively and there was no difference between both values. Constant contractions induced by 10(-5)M PE in both rings were inhibited by the same doses of nicardipine in a dose-dependent fashion. The IC50s were 2.8x10(-4)M in thoracic aorta and 2.9x10(-5)M in carotid artery respectively, and the former was about 10 times greater than the latter. In Ca2+ free PSS, KCI did not produce any contractionn. Though constant and reproducible in NPSS, PE-induced contraction was transient and not reproducible in Ca2+ free PSS. The contraction in both rings were weakened to about 70% of those in NPSS. Pretreatment with nicardipine in the range of doses from 10-8M to 10-5M hardly affected the PE-induced contraction and the largest dose 10(-4)M slightly inhibited the contraction. Intravenous injection of nicardipine 10 to 1000microg/kg decreased blood pressure and heart rate of rabbits in a dose-dependent manner. The % decrease of heart rate was much smaller in comparison with the %decrease of blood presseure. Pressor effect of 30microg/kg PE was dose-dependently inhibited after treatment with nicardipine 10 to 1000microg/kg and ID50 was 314microg/kg(6.1x10(-7)mole/kg). Above results suggest that nicardipine blocks extracellulr Ca2+ influx by membrane depolarization and in a part by alpha1-adrenceptors, then relaxes arterial smooth muscles in rabbits.

We report a case of recurrent herpes genitalis in a 5-year-old girl which was considered to result from childhood sexual abuse. The skin lesion was an eroded erythematous macule with overlying multiple vesicles on the labia majora. We detected Herpes simplex virus DNA by using the polymerase chain reaction (PCR) in a biopsy specimen from the vesicular lesion.

Our study was performed to evaluate the efficacy of anthralin-UVB therapy for psoriasis by simplifying the conventional Ingram regimen, 34 patients(21 admitted, and 13 OPD patients) were included in our study and the resulti can be summarized as follows. 1. There were no cases of treatment failure. 16 patients(76. 2%) out of the 2l admitted patients and 7 patients(53.8%) out of the 13 OPD patients showed clearing. 2. In the case of the admitted patients, the mean numbers of therapy(days) of the improved patients reaching grade 4 were 12. 0(18. 1 days) in the trunk lesions and 15. 5 (22. 0 days) in the extremity lesions' and those of the cleared patients reaching grade 4 were 11. 2(16. 0 days) in the trunk lesions, and 13. 4(lg. 5 days) in the extremity lesions, but the difference was not significant statistically(pp o.ps). The difference between the therapeutic effects of the admitted and the OPD patients was significant statistically(p<0. 05). 3. There were some notable side effects such as staining, pruritus, and erythema, but there were no cases of therapy termination.

A 45 year old male patient complained of mucous fluid drainage in the vicinity af the manubrium sterni for 5 years. Skin around the lesion had normal appearance except pinpoint sized sinus opening. H.istopathology showed a cyst in the upper and mid-dermis which consisted of pseudoetratified columnar epithelium with interspersed goblet cells. Goblet; cells were confirmed by positive stain to D-PAS and alcian blue and by metachromatic stain to toluidine blue. VFe present here a case of cutaneous bronchogenic cyst clinically and histopathologically which is thought to be the first cace in Korea.
