Microsurgical replantation of the external ear

Cosmetically, the optimal management of the amputated external ear is microsurgical replantation. Although technically demanding, replantation is possible by the experienced surgeon. Success frequently requires the use of vein grafts, heparinization, and the alleviation of venous congestion with medicinal leeches or frequent stab wounds.     

Evaluation of radical prostatectomy capsular margins of resection. The significance of margins designated as negative, closely approaching, and positive

Capsular margins of resection in radical prostatectomy specimens performed for carcinoma of the prostate are difficult to assess because of the scant soft tissue removed with the prostate. There is little objective information as to the validity of what are designated as positive or negative capsular margins of resection. From January 1, 1984 through June 30, 1989 there were 40 radical prostatectomies performed in which the prostate was initially removed leaving the neurovascular bundle within the patient in order to preserve potency. However, based on the surgeons' gross examination of the prostate at the time of radical prostatectomy, the neurovascular bundle was then subsequently removed during the same operation and submitted to pathology as a separate specimen. In these 40 cases the capsular margin in the region of the neurovascular bundle was assessed blindly without knowledge of tumor presence or absence in the subsequently resected neurovascular bundle, and then compared to whether the neurovascular bundle contained tumor. Of the 10 cases called positive based on review of the radical prostatectomy, only six neurovascular bundles (60%) contained tumor. Eight cases had equivocal margins with tumor extending just to the inked margin, and only one (12.5%) had tumor in the neurovascular bundle. All 20 cases with negative assigned margins had complete removal of tumor from this area with none of the neurovascular bundles containing tumor. This study demonstrated that negative capsular margins in radical prostatectomy specimens often contain only a scant amount of soft tissue. Of the 33 cases with true negative margins, the amount of soft tissue between the inked margin and tumor was only greater than 1 mm in two cases and less than or equal to 1 m in 20 cases (less than 0.5 mm in 13 cases with less than 0.25 mm in eight of these cases). Furthermore, 11 cases with tumor extending to the inked margin of resection showed no residual tumor in additional tissue removed from these regions.     

The clinico-statistical characteristics of the testicular generative function in male subfertility following mumps

The paper emphasized the role of mumps complicated by orchitis in the etiology of male subfertility with allowances for a possible development of testicular degeneration in the course of epidemic parotiditis alone, i.e. without clinically evident orchitis. To distinguish the impact of mumps sustained in childhood on the infertility development clinical and laboratory investigations would be advisable in the majority of subfertile males. The results of clinical and statistical study of 865 infertile males aged between 20 and 36 yrs whose marital life varied from 8 mos to 12 yrs were reported. Anamnestic evidence of epidemic parotiditis sustained at the age of 5-13 yrs was found in 174 examinees (20.1 per cent). Spermographic data on subfertile males with a history of mumps were exposed to statistical computation and correlated with the data on 200 subfertile males who avoided the disease and the data on 22 healthy fertile males. The authors noted significantly low (p less than 0.05) contents of ejaculate spermatozoa in subfertile males with a history of mumps and a significantly low number of morphologically normal spermatozoa (p less than 0.001) in comparison to those values in subfertile males without a history of epidemic parotiditis.     

Ceruloplasmin activity in blood serum in stomach and duodenal ulcers

An examination of 100 patients with ulcer disease of the stomach duodenum and 20 practically healthy people has shown that the level of extracellular antioxidant enzyme defense (ceruloplasmin) is higher than those in practically healthy people. This dependence was most pronounced in the group of patients requiring surgical interventions. In the process of treatment the level of ceruloplasmin activity gradually decreased, without reaching normal values. The level of ceruloplasmin activity in patients with ulcer disease of the stomach and duodenum are thought to characterize the state of compensatory reactions in these patients.     

A case of double cancer: renal cell carcinoma and transitional cell carcinoma of urinary bladder

This is a case report on a patient with double cancer of kidney and urinary bladder. The patient was a 65-year-old female, and she was admitted with the chief complaint of gross hematuria and right flank pain. After careful examinations, she was diagnosed with right nonfunctioning kidney caused by invasive bladder cancer. Computerized tomography incidentally revealed a mass in the upper pole of the left kidney. Selective left renal arteriography showed stretched arteries and irregularity and tortuosity of the smaller vessels. She was diagnosed with double cancer of bladder and left kidney. Owing to the damage of the right renal function, left partial nephrectomy, total cystectomy, right nephroureterectomy and left ureterocutaneostomy were performed. According to DMSA scintigraphy measured 15 days later, the uptake value of the left kidney was 13.25%, compared to the preoperative value of 25.62%. To date, this case is 36th reported case in Japan.     

Soft tissue sarcomas of the head and neck in adults

We reviewed the clinical records and pathologic material of 176 adults with primary soft tissue sarcomas treated at Memorial Sloan-Kettering Cancer Center between 1950 and 1985. Seventy-two patients (41%) had low-grade sarcomas and 104 (59%) had high-grade sarcomas. All but 18 patients underwent some form of excision as initial therapy. Adjuvant radiotherapy and chemotherapy combined with surgical excision showed no significant effect. A significantly increased risk of treatment failure was associated with large tumor size, positive surgical margins, bone involvement, local recurrence, metastatic spread, and high histologic grade. Except for recurrence, the p value by univariate analysis in the log-rank test for comparison of survival according to these clinical and pathologic characteristics was p less than 0.0001. Although the overall survival was 75% at 2 years, 55% at 5 years, and 46% at 10 years, only 20% of the patients with high-grade sarcomas were alive 10 years after treatment. Most patients with rhabdomyosarcoma, high-grade peripheral nerve tumor, and high-grade fibrous histiocytoma and all patients with high-grade angiosarcoma died of disease less than 5 years after diagnosis. New therapeutic strategies are needed to improve the survival of adult patients with high-grade soft tissue sarcomas of the head and neck.     

The management of the painful first metatarsophalangeal joint in the older patient. Arthrodesis or Keller's arthroplasty?

We report a prospective randomised trial comparing Keller's arthroplasty and arthrodesis of the first metatarsophalangeal joint for the management of symptomatic hallux valgus and hallux rigidus in the older patient. In 81 patients (110 feet), with a minimum of two years follow-up, both procedures gave a similar degree of patient satisfaction and symptom relief. The incidence of metatarsalgia was also similar. As there were no obvious advantages to arthrodesis, and since six out of 50 arthrodesed toes required revision, we suggest that Keller's arthroplasty is the better operation in these patients.
