Unsuspected pheochromocytoma in a surgical patients may lead to serial complications. These include extreme hypertension, taehycardia and cardiac arrythmias which lead to cardiac arrest, cerebrovascular accident and renal failure in the postoperative period. Pheochromocytoma arising in the urinary bladder is a rare tumor. We recently experienced a case of pheochromocytoma which was found during transurethral resection for biopsy of bladder tumor under spinal anesthesia. The blood pressure suddenly rose during resection. of the tumor. It was difficult to arrive at a correct diagnosis in this case because of the predominant bladder symptams without hypertenaive attack. Therefore, final diagnosis was made as the pheochromocytoms after histological examination. The resection of the tumor was performed under general anesthesia after careful studies. The patient was not treated during the preoperative period as she had no particular symptoms, but Regitine was glven during surgery. Regitine was used twice to control the transient hypertension during manipulation of the tumor. After removal of the tumor, the blood pressure was well regulated without vasopressor drugs. We report a case of pheochromocytoma of urinary bladder with successful anesthesia management and the use of neuroleptanesthetics.

This report concerns a child who developed left ; Iung collapse during induction of anesthesia for suture ligation of patent ductus arteriosus. Acute massive collapse of a lobe, a whole lung or even both lungs in the space of a few minutes without apparent cause is said to be a rare elinical entity. Clinically this condition is manifested by difficulty in breathing or in inflation of the lung. On auscultation, there may be rhonchi or no sound of any air entry into the lung. If unrelieved, this condition will progress, with hypoxia and cardiac arrest. " We observed that the affected lung expanded during inflation with very high pressure ventilation, and then the collapsed lung was smoothly inflated after suture ligation of patent ductua arteriosus without any specific management. It appears that the development of lung collapse is not through the wrong choice of agents or technics of anesthesia, but from failure to appreciate the hemodynamics of ductus arteriosus or unknown factors. We could not find a definite mechanism of lung collapse, but there are contributing factors including compression of a main brobchus, bronchial secretion, decrease of surfactant and others. The operation was successful and she recovered satisfactorily.

Adenomatoid tumor is extremely rare benign neoplasm occurring in the genital tract. They are mesothelial origin tumors and frequently found in the testis, epididymis, tunica vaginalis, or spermatic cord in male. But most adenomatoid tumors are found near or in epididymis. While in female they are usually located in the fallopian tube, uterus, and ovary. Adenomatoid tumors are usually small, firm or solid, and asymptomatic, these are clinically found or routine physical examination. They are usually less than 2cm in diameter, but may measure up to 5cm, Histologically the tumor consists of tubules and gland like spaces lined with cuboidal or flattened in a fibrous stroma. The tumor was first described and adenomyoma by Sakaguchi in 1915. Since that time there have been numerous case reports of similar tumors. But the term, adenomatoid tumor, introduced by Golde and Ash in 1945 seems to have been even more widely used. Recently we experienced a case of adenomatoid tumor of epididymis, which was found incidentally during physical examination and confirmed by excisional biopsy in a patient who complained lower abdominal pain.

To investigate the earlier cellular alterations(Glucose-6-Pase activity and morphologic features) caused by a hepatotoxin, thioacetamide (TAA), a single dose of the agent (200mg per kg of body weight) was given intraperitoneally to mice, which were sacrificed at intervals of 4, 8 or 16 hours after corresponding treatments. For histochemical study of glucose-6-phosphatase (G6Pase) activity, unfixed frozen sections were incubation of the Wachstein and Meisel medium and stained. The smallest pieces of liver tissue were fixed in glutaraldehyde and osmic acid, and stained by the routine electron-microscopic techniques. Some pieces of liver were fixed in 10% formalin, embedded in paraffin, and stained with hematoxylin and eosin. There was a rapid and progressive loss of G6Pase activity, in an orderly time sequence, in the experimental group. There were also morphologic changes: loss of cytoplasmic basophilia, cell infiltration and necrosis in the centrilobular and intermediate zones, and an increase of sER, small vesicles and ribosomes in the cytoplasm of hepatocytes, the marked changes of nuclei and nucleoli, and a slight increase of lipid droplets in the cytoplasm at 16 hours after intoxication. The correlation between these cellular alterations was discussed in view of mechanisms in the hepatotoxic action.

The auther had utilized the continuous irrigation with saline and antibiotics to 1 case of serpent corneal ulcer and 2 cases alkaline burn by Lippas' original technique. Two cases of alkaline burn were healed up without any complications and one case of serpent corneal ulcer showed relatively good result. According to review through a few literature, the method of continuous irrigation is much better one than any other systemic or local administration of the drug to the particular external ocular disease.

PURPOSE: To compare ocular biometry and refractive results measured using conventional applanation ultrasonography and 3 different optical interferometries, Lenstar LS900(R), AL-Scan(R) and OA-2000(R). METHODS: The biometries of 31 cataractous eyes were measured using ultrasonography, Lenstar LS900(R), AL-Scan(R) or OA-2000(R). The axial length, anterior chamber depth and keratometry were measured. The SRK/T formula was used to calculate intraocular lens power. Two months after cataract surgery, the refractive outcome was determined and results from the 4 different biometry methods were compared. RESULTS: Axial lengths were 23.39 +/- 0.95 mm, 23.42 +/- 0.98 mm, 23.43 +/- 0.98 mm and 23.44 +/- 0.98 mm measured using ultrasonography, Lenstar LS900(R), AL-Scan(R) and OA-2000(R), respectively with no statistically significant differences observed (p = 0.996). The anterior chamber depth and keratometry were 3.14 +/- 0.41 mm, 3.10 +/- 0.38 mm and 3.13 +/- 0.39 mm (p = 0.936) and 44.41 +/- 1.52 D, 44.54 +/- 1.57 D and 44.44 +/- 1.52 D (p = 0.937) for Lenstar LS900(R), AL-Scan(R) and OA-2000(R) respectively. There were no statistically significant differences between the 3 optical devices. The mean absolute error of the 4 different devices were not statistically significant (p = 0.722). CONCLUSIONS: The ocular biometric measurements and prediction of postoperative refraction using ultrasonography, Lenstar LS900(R), AL-Scan(R) or OA-2000(R) showed no significant differences.

Meningioma although quite common in adults, are extremely rare in infant. Only 25cases of meningioma in patients younger than 1 year old have been reported in the world literature. The authors report a case of meningioma associated wth multiple cysts in a 6-month-old infant.
