Cryopreserved arterial allografts in the treatment of prosthetic graft infections.

AIM: The purpose of this study was to evaluate the effectiveness of cryopreserved arterial allografts in the management of prosthetic graft infection. MATERIAL AND METHODS: Over a 5-year period 45 patients with infection of prosthetic vascular grafts were treated. There were 39 intra-abdominal infected grafts (group I) and six extra-abdominal infected grafts (group II). Treatment consisted of total graft removal and in situ or extra-anatomic implantation of cryopreserved arterial allografts. Six patients were operated on as an emergency. Four patients presented with aorto-enteric fistula. Follow-up ranged from 30 to 78 months. RESULTS: There were six in-hospital deaths and two additional patient deaths during follow-up, yielding an overall mortality rate of 18%. Six patients died due to complications directly related to infection or insertion of an allograft. Combined short and long-term mortality rate was much higher in patients operated on as an emergency (67%) compared to elective cases (11%). Patients with aorto-enteric fistula had the highest mortality rate (75%). Primary and secondary 3-year allograft patency rates for group I were 84 and 94%, respectively and for group II were 60 and 80%, respectively. CONCLUSIONS: Aortic allografts are useful in the treatment of infection of major vascular prosthetic grafts, except for patients with aorto-enteric fistula. Patients with infection of the prosthetic graft should be promptly assessed for graft removal, since results of elective surgery are much better than results of emergency procedures.

[A case of maxillary neurosarcoma].

A case of neurosarcoma located in maxillary sinus is presented. The patient was 62 years old women who complained of nasal obstruction, epistaxis and headache. Results of physical examination showed a giant mass filling the nasal cavity and maxillary sinus. The lesion was completely resected by lateral rhinotomy way. After the operation histopathological diagnosis was difficult, one pathologist recognised schwannoma benignum other one sarcoma. Finally postoperative diagnosis was schwannoma benignum, it was misdiagnosis. Two years later the patient was surgically treated again because of tumor recurrence. These time pathological diagnosis was neurosarcoma. Radiotherapy was done as well. The patient died 18 months after treatment, tumor regrowth and generalization metastases was reason of the death.

[Tumors of the parotid glands in the material of the Department of otolaryngology of the Medical Academy in Warsaw in 1986-1995].

In the Department of Otolaryngology, Medical Academy in Warsaw, 332 patients were surgically treated between 1986 and 1995 because of parotid gland tumors. In 275 cases benign tumors, in 57 cases--malignant tumors were observed. The majority of benign tumors were pleomorphic adenoma (61.45%) and lymphadenoma (22.54%); the majority of malignant tumors were adenocarcinoma (28%), adenoid cystic carcinoma (21%), mucoepidermoid carcinoma (15.78%). All patients with benign tumors were surgically treated, patients with malignant tumors were operated on and irradiated. The surgical procedure used superficial parotidectomy and total parotidectomy with preservation of facial nerve where possible. Ten patients required total parotidectomy with facial nerve resection because of malignant tumors, six patients had neck dissection performed. Of the 57 patients treated on account of malignant tumors 43 survived; 14 patients died of a local recurrence or generalization neoplasm disease.

[Metastasis of the cutis malignant melanoma of the parotid gland].

The authors presented a rare case of metastases of the cutis malignant melanoma to the parotid nodes. The attention was directed towards clinical aspects and diagnostic difficulties. Basing on data from the literature frequency and possibilities of cutis malignant melanoma metastases were analysed.

[The value of total contact casting in treatment of neuropathic foot ulcers in diabetic patients].

Neuropathic foot ulcers in diabetic patients pose great difficulties in treatment. Total contact casting is one of the available methods. It is thought to distribute the pressure evenly over the entire surface of the foot. The purpose of the study was the evaluation of the total contact casting as a method of treatment of neuropathic foot ulcers in diabetic patients. Ten diabetic patients with neuropathic foot ulcers were treated with total contact casting. The inclusion criteria were good arterial blood supply and the absence of bone, joints or surrounding soft tissue infection. The mean area of the ulcers was 1.9 cm2 (1.3-3.6 cm2). The average duration of the ulcer prior to commencement of the treatment was 10 months. Total contact cast was applied after thorough surgical debridement and covering of the ulcer with occlusive dressing. The casts were changed every six to ten days. The ulcers healed in 9 out of 10 treated patients. The healing time averaged two months. In one patient development of soft tissue infection necessitated discontinuation of the treatment and performing open ray amputation. In four patients superficial ulcerations of the skin of the dorsal aspect of the toes developed. They resulted in prolonged duration of the treatment. Total contact casting in adequately qualified and reliable patients is safe and effective method of treatment of neuropathic foot ulcers in diabetes.

[Reconstructive surgery in an advanced laryngeal neoplasm].

The case of the extensive laryngeal cancer recurrence after radiotherapy was described. The authors were discussed treatment surgery it with reconstruction of the tissue defect. The skin defect was reconstructed with the pectoralis mayor myocutaneous island flap, the pharyngeal secondary fistula was reconstructed with the Trapezius myocutaneous flap.

[Indications and counterindications for topical corticosteroidotherapy].

This paper presents indications for topical corticosteroidotherapy in rhinitis and nasal polyps. The differential diagnosis including etiology and pathogenesis of diseases especially aspirin intolerance, are taken into consideration. The main indication for topical corticosteroidotherapy is local nasal eosinophilia. The authors everyday clinical practice help to establish considerations for the use of corticosteroids.

[Investigation of variability in the vascularity of trapezius musculo-cutaneous flaps].

The search on the human body cadavers was done to determine the exact localization of the various cutaneous island flaps depending on the course of the blood vessels. The latex solution stained with the prussian blue was injected directly into the thyro-cervical trunk or subclavian arteries. Afterwards the island musculocutaneous flaps from various regions of the trapezius muscle were performed. The whole number of the performed flaps were 20. The search confirmed the possibility of formation island flaps from various regions of the trapezius muscle.

[Evaluation of the effect of auditory fatigue on the human ear by auditory brain stem responses (ABR). I. Effect of auditory fatigue on temporary threshold shifts of ABR].

The effects of auditory fatigue on auditory brainstem responses (ABR) were investigated in 23 normal-hearing subjects. ABR was recorded before and after exposure to fatiguing noise. Behaviourally, the auditory fatigue was tested using a temporary threshold shifts (TTS) paradigm. The latency of waves I, III, V and interwave intervals I-III, III-V, I-V were analysed as functions of stimulus intensity. In post-exposure recordings a threshold elevation, significant increase of all waves latency, increase of interwave-interval III-V at 40,50,60 dB nHL and unaltered intervals I-III, I-V were observed.

[Evaluation of the effect of auditory fatigue on the human ear based on the measurement of brain stem auditory potentials (ABR). II. Relation of temporary auditory threshold shift and changes in the latency of wave V].

The relationship between temporary threshold shift (TTS) and latency changes of auditory brainstem responses (ABR) induced by noise exposure was studied in 23 normal-hearing subjects. Shift in latency wave V at 40 dB nHL of stimulus intensity as a result of auditory fatigue showed no significant correlation with TTS at 4 kHz. The great intersubject variability of shifts in latency wave V as a result of auditory fatigue suggests that this shift may be a useful measure of individual susceptibility to noise.
