To understand better the complex natural course of HBV infection, the expression patterns of HBcAg and HBsAg in the liver of 51 inactive serum HBsAg carriers (24 CPH and 27 NPD) were studied by immunohistochemical methods. The inactive serum HBsAg carriers were devided into 3 groups by the following expression patterns of serum HBeAg/anti-HBe status and tissue HBcAg and HBsAg. Pattern A (18 cases) : HBeAg+, cHBcAg+ (94.4%), mHBsAg+ (61.1%), pATTERN B (14 cases) : anti-HBe+, nHBcAg+, cHBsAg+, Pattern C (19 cases) : anti-HBe+, HBcAg-, cHBsAg+ (89.5%). There were no significant differences between CPH and NPD, lthough the core free pattern was more common in the latter. The cHBcAg was expressed in 17 of 18 (94.4%) HBeAg seropositive cases but only one of 33 cases with serum anti-HBe, suggesting that the cHBcAg is intimately related to HBeAg. Since the inactive HBsAg carriers also expressed cHBcAg and/or mHBsAg, the necro-inflammatory activity of HBV infected liver is assumed to depend on the host immune response rather than their presence alone

OBJECTIVE: To explore the clinical value of postoperative follow-up examination of F-wave and H-reflex in patients with lumbosacral radiculopathy and to clarify optimal timing of follow-up examination. METHOD: The subjects were 17 patients with unilateral lumbosacral radiculopathy caused by disc herniation. In patients with the L5 radiculopathy, F-waves were obtained from extensor digitorum brevis and six parameters including minimal latency per height were used. In patients with the S1 radiculopathy, H-reflexes were obtained from gastrocnemius and amplitude and minimal latency were used as parameters. These parameters were evaluated preoperatively and postoperatively at week 1, 3, 6. These changes of the parameters and clinical findings were related. RESULTS: The parameters of peroneal F-wave and tibial H-reflex showed significant improvement at 3 weeks and 6 weeks after surgery. The improvements of these parameters were not related with clinical improvement at 1 week after operation, but these were significantly related with improvement of pain and muscle weakness at 3 weeks after operation. CONCLUSION: These findings suggested that follow-up examination of F-wave and H-reflex were valuable for objective assessment of lumbosacral radiculopathy after operation and the optimal timing for follow-up study was 3 weeks after operation.

Peritoneal dialysis has been widely considered to be the dialytic treatment of choice for acute renal failure in infants and young children, because the technique is simple, safe and easily adapted for these patients. Also peritoneal dialysis in infants might have more effective ultrafiltration and clearance than in adults. In certain circumstances associated with hemodynamic instability, ordinary volume peritoneal dialysis (30-50 ml/kg body weight per exchange) or hemodialysis may not be suitable unfortunately. But frequent cycled, low volume, high concentration peritoneal dialysis may be more available to manage the acute renal failure of newborns and infants. Seven infants underwent peritoneal dialysis for hemodynamically unstable acute renal failure with low exchange volume (14.2±4.2 ml/kg), short exchange time (30 to 45 minutes) and hypertonic glucose solution (4.25% dextrose). Age was 1.9±1.3 months and body weight was 4.6±1.6 kg. Etiology of acute renal failure was secondary to sepsis with or without shock (5 cases) and postcardiac operation (2 cases). Catheter was inserted percutaneously with pigtail catheter or Tenkhoff catheter by Seldinger method. Dialysate was commercially obtained Peritosol which contained sodium, chloride, potassium, magnesium, lactate and calcium. Net ultrafiltration (ml/min) showed no difference between low volume dialysis and control (0.27±0.09 versus 0.29±0.09). Blood BUN decreased from 95.7±37.5 to 75.7±25.9 mg/dl and blood pH increased from 7.122±0.048 to 7.326±0.063 after 24 hours of peritoneal dialysis. We experienced hyperglycemia which were controlled by insulin (2 episodes), leakage at the exit site (2), mild hyponatremia (1) and Escherichia coli peritonitis (1). Two children of low volume dialysis died despite the treatment. In our experience, low volume and high concentration peritoneal dialysis with frequent exchange may have sufficient ultrafiltration and clearance without significant complications in the certain risked acute renal failure of infants.

We report a medullary carcinoma of the thyroid gland with a coexisting occult sclerosing papillary carcinoma. This rare case, in that the two types of carcinoma are completely separated and not intermixed together, is different from the previously reported mixed follicular and parafollicular cell carcinomas of the thyroid gland, so-called "differentiated thyroid carcinoma, intermediate type". The two separate tumors of the present case are undoubtedly of coincidental double primaries, and it can be a assumed that at least some of the mixed follicular and parafollicular cell carcinomas are results of collision of carcinomas derived from two embryogenetically different cell types.

Malignant fibrous histiocytoma (MFH) of the heart is a very rare disease. It is difficult to distinguish from myxoma which is most common benign cardiac tumor. Prognosis of malignant fibrous histiocytoma (MFH) of the heart is known to be fatal despite of medical and surgical treatment in contrast to benign tumors. A primary myxoid malignant fibrous histiocytoma of the left atrium was diagnosed in a 58 years old woman. The mass was removed incompletely by operation. The patient did not receive either chemotherapy or radiotherapy. However, the patient is still alive for more than fifteen months after the initial presentation. We report a case of malignant fi brous histiocytoma (MFH) with reviewing the current references.
