Neuroblastoma is the most common solid malignancy in childhood. However, a neuroblastoma presenting as bilateral and multifocal is very rare. A male newborn weighing 2.7 kg was born by normal vaginal delivery at 39 weeks' gestation to a 27-year-old mother who had a normal pregnancy. He was in good condition at birth but presented palpable masses in the both upper abdomen and both side of the neck. Ultrasound examination showed the lesions to be $3{\times}3cm$ sized calcified mass in right suprarenal area and $5{\times}3cm$ sized homogenous mass in left suprarenal area. The abdominal mass was also examined by computed tomography with similar findings. With the impression of bilateral neuroblastoma or metastatic spread, the laparotomy was performed on the 13th day of life. Frozen section of biopsy of the left neck mass was obtained, which showed neuroblastoma. Intraoperative findings revealed bilateral adrenal masses which were distinct and anatomically separate. Bilateral adrenalectomy was accomplished and the initial postoperative course was uneventful. The patient was discharged for hopeless and expired at age 45 days. We present bilateral adrenal neuroblastoma considered to be simultaneous occurrence rather than metastases from one site to another.

To directly test if elevated glucocorticoids are required for fasting-induced regulation of growth hormone (GH)-releasing hormone (GHRH), GHRH receptors (GHRH-R) and ghrelin receptors (GHS-R) expression, male rats were bilaterally adrenalectomized or sham operated. After 7 days, animals were fed ad libitum or fasted for 48 h. Bilateral adrenalectomy increased hypothalamic GHRH to 146% and decreased neuropeptide Y (NPY) mRNA to 54% of SHAM controls. Pituitary GHRH-R and GHS-R mRNA levels were decreased by adrenalectomy to 30% and 80% of shamoperated controls. In shamoperated rats, fasting suppressed hypothalamic GHRH (49%) and stimulated NPY (166%) mRNA levels, while fasting increased pituitary GHRH-R (391%) and GHS-R (218%) mRNA levels. However, in adrenalectomized rats, fasting failed to alter pituitary GHRH-R mRNA levels, while the fasting-induced suppression of GHRH and elevation of NPY and GHS-R mRNA levels remained intact. In fasted adrenalectomized rats, corticosterone replacement increased GHRH-R mRNA levels and intensified the fasting-induced decrease in GHRH, but did not alter NPY or GHS-R response. These data suggest that elevated glucocorticoids mediate the effects of fasting on hypothalamic GHRH and pituitary GHRH-R expression, while glucocorticoids are likely not the major determinant in fasting-induced increases in hypothalamic NPY and pituitary GHS-R expression.

Primary aldosteronism has been found more often among patients with hypertension. Primary aldosteronism can be caused by an aldosterone-producing adenoma, bilateral adrenal hyperplasia, or rarely by an adrenal carcinoma. An initial diagnostic test for aldosteronism is a measurement of the plasma renin activity and aldosterone concentration. For example, up to 20% of patients with hypertension showed increased plasma aldosterone concentration/renin activity ratio. If surgery is planned, an adrenal vein sampling is necessary for exact localization. Spironolactone, an aldosterone antagonist, is the drug of choice for patients with an aldosterone-producing adenoma or hyperplasia. It can control elevated blood pressure in most primary aldosteronism patients. However, unilateral laparoscopic adrenalectomy is the best treatment for aldosterone-producing adenoma or asymmetrical aldosterone production in patients with uncontrolled hypertension. Here we report a patient with primary aldosteronism caused by unilateral adrenal hyperplasia and a contralateral adrenal adenoma who required as many as five different kinds of antihypertensive medications for controlling elevated blood pressure. The adrenal adenoma was successfully removed by unilateral adrenalectomy and the blood pressure had been controlled well after the surgery.

This study was conducted to see whether the hippocampectomy exerted facilitatory influence upon gastric ulceration in animals, and if so, whether the effect of hippocampectomy could be suppressed by adrenalectomy. 107 male rats were divided into 5 groups: rats that had over 90% of their hippocampal tissue removed through an opening on each side of the cerebral cortex(hippocampal group, N=21), rats that received bilateral adrenalectomy(adrenal group, N=29), rats that received adrenalectomy as well as hippocampectomy(hippocampo-adrenal group, N=10), rats that received damage to each side of the cortex over the hippocampus(cortical control group, N=20), and rats that had solely their head skin incised(normal control group, N=27). All rats were kept without restraint or food deprivation until on the 25th day after surgery, the stomach of each rat was inflated with 7ml of physiological saline and then removed under deep anesthesia. The mucosal surface was sketched under dissecting microscope, and enlarged photographs$(4{\times})$ were taken. The percentage of animals developing gastric ulcer in each animal group was calculated, the number of ulcer in each stomach was counted, and the total area of ulceration per stomach was measured on the Photograph with the aid of superimposed graph paper and expressed as permillage of total area of the glandular mucosa. Results obtained were as follows: 1. The percentage of animals developing gastric ulcer was significantly larger in the hippocampal group than they were in the hippocampo-adrenal, the adrenal, the cortical, and the normal control groups. 2. The mean number of ulcer per stomach was significantly larger in the hippocampal group than they were in the adrenal, the cortical control, and the normal control groups, while no significant difference existed between the hippocampal and the hippocampo-adrenal groups. 3. Total area of ulcer per stomach was significantly larger in the hippocampal group than they were in the cortical control and the normal control groups, but no significant differ-ence existed among the hippocampal, the adrenal, and the hippocampo·adrenal groups. 4. All measured values of the adrenal group were not significantly different from those of the hippocampo-adrenal, the cortical control, and the normal control groups. It is inferred from the above results that the hippocampus exerts an inhibitory influence upon gastric ulceration and that the hippocampal influence is mediated only partly through suppression of pituitary·adrenal activity.

저자들은 산전 초음파에서 복부 종괴가 발견되어 관찰 도중 복부 팽만과 호흡 부전이 발생하여 방사선요법과 항암요법으로 치료하였던 양측성 선천성 신경모세포종 1례를 문헌 고찰과 함께 보고하는 바이다. 선천성 양측성 신경모세포종의 경우 임상경과를 잘 관찰하고 치료여부를 결정하여야 할 것으로 생각된다.

연구배경 : 폐효모균증은 중추 신경계 효모균증에 비해 비교적 나타나나 근래에 폐질환에 대한 진단의 기저 질환의 증가등으로 인해 발생 빈도가 점차 증가하고 있다. 또 이 질환의 아급성으로 나타나는 비 특이적인 증상들로 인해 국내에 많은 폐질환과 오인하여 치료하기가 쉽다. 이에 저자들은 국내에 폐효모균증과 본원에서 경험한 예를 대상으로 국내에서의 폐효모균증의 임상 양상을 알아보고자 한다. 방 법 : 1985년부터 1996년까지 한양대학교 의과대화 부속병원에서 경험한 5예와 1984년부터 1996년까지 국내 문헌에 발표된 9예의 폐효모균증 환자를 대상으로 후향적으로 의무 기록과 보고 문헌을 조사하였다. 결 과 : 50대 이상의 고령에서 주로 발생하며 남녀비는 3.6 : 1로 남자에서 호발하였다. 변역 상태를 저하시키는 기자 질환이 6예에서 있었으나 나머지 8예는 기저 질환이 없어 정상인에게서도 폐효모균증이 발생할 수 있음을 보여주고 있다. 임상증상은 증상이 없거나 비 특이적인 호흡기 증상들이 아급성으로 나타나고 있었으며 이로 인해 정확한 진단이 이루어지기 전에 폐결핵으로 오인 치료된 예가 많았다. 흉부 방사선 검사상 고립성 폐경화와 광범한 폐침윤이 흔한 소견이었으며 비교적 드물다는 늑막 삼출, 폐문부 림프절 비대, 공동 형성등도 관찰 되었다. 특별한 호발부위는 없었다. 진단 방법으로는 주로 폐생검을 통한 조직학적 방법이 이용되었고 그 중 경피적 세침 흡인 생검술이 가장 많이 사용되었다. cryptococcus neoformans에 대한 객담 도말 검사, 배양검사와 혈청에서 검사한 latex agglutination test논 낮은 양성률을 보여주었다. 치료는 여러 항 진균제 (fluconazole, amphotericin B, flucytosine, ketonazole), 수술 또는 이들을 병합한 방법등으로 다양하게 사용되었다. 1990년 이후에는 경구 투여가 가능한 flucon-azole 또는 ketoconazole 등을 이용한 치료가 증가하고 있는 양상이다. 치료후 대개 4개월이내에 흉부 방사선상 병변의 흔적만 남든지 거의 소설되는 양상을 보였다. 재발한 예는 없었다. 결 론 : 폐효모균증은 국내 폐렴의 드문 원인이나 1985년이 후 꾸준히 보고되고 있다. 호발 연령은 50대 이후이나 젊고 기저 질환이 없는 예에서도 발생하여 정상인에서도 이 질환의 가능성에 대해 고려해야 하며 아급성의 비 특이적인 증상을 호소하며 일반 항생제에 잘 반응하지 않아 폐결핵과의 감별진단이 중요하다. 객담 및 혈청 검사로는 진단률이 낮아 폐조직 생검 등의 조직학적 확진이 필요하며 아직 치료 방법이 확립되어 있지 않지만 근래 간편하게 경구로 복용할 수 있고 효과적인 약제가 선호되고 있다.
