[Reconstruction of the distal lower extremity defects with distal pedicled fasciocutaneous flaps].

Soft-tissue coverage of defects in the distal lower extremity has its limitations because of minimal blood supply to the skin and the thin muscle layer. Split-thickness skin grafting is impossible in cases of defects of tendons or bones. Local flaps are applicable only for smaller defects. With the cross-leg flaps, it is necessary to immobilize the patient for a long time. Special microsurgical technique and knowledge are needed for the free flaps. Fasciocutaneous flaps of the lower extremity after Donski and Fodgestam are simpler and safer than the other methods. From 1987 to 1992, this method was successfully used on 15 patients in the Department of Plastic Surgery of Sişli Etfal Hospital in Istanbul. In the two-thirds of those patients, accidents were the cause of the defects. The advantages of this methods are: simpler technique, larger flap-surface, earlier mobilisation of patients, better adaptation of the flap to its neighbourhood regarding colour and thickness.

Investigations of the frequency of DNA strand breakage and cross-linking and of sister chromatid exchange frequency in the lymphocytes of female workers exposed to benzene and toluene.

Peripheral lymphocyte DNA damage as measured by the method of alkaline filter elution and the frequency of sister chromatid exchange (SCE) in lymphocytes was investigated for a group of 20 female workers of a shoemaking plant who were exposed to benzene and toluene, primarily below the German threshold limit value of 5 and 100 p.p.m. respectively; the results were compared with those from a control group. In the female workers significantly raised (P less than 0.05) SCE values were found. The relative DNA elution rate through polycarbonate filters was significantly increased (P less than 0.001). The elution rate through polyvinylidene fluoride (HVLP) filters showed a tendency to increase (P = 0.052), which must be interpreted as indicating increased DNA strand breakage. The SCE rates of the female workers were significantly correlated (P less than 0.01) with the relative DNA elution rate through HVLP filters. There was no correlation with the actual benzene and toluene uptake measured by personal air monitoring. Four months after cessation of work, DNA strand breakage decreased significantly (P less than 0.05) in blood samples of six reinvestigated female workers.

Intrascrotal extratesticular malignant schwannoma.

We report a rare case of intrascrotal extratesticular malignant schwannoma with rhabdomyoblastic features in a 48-year-old man. Malignant schwannomas, which arise from the peripheral nerves, usually occur in the extremities, the trunk or paravertebral areas. The patient had no manifestation of von Recklinghausen's disease. To our knowledge, there has been no intrascrotal extratesticular malignant schwannoma reported.

Emphysematous pyelonephritis with pneumocystitis.

Emphysematous pyelonephritis is an acute infectious process mostly associated with diabetes and obstruction. It is a life-threatening illness and treatment generally involves antibiotic therapy, surgical drainage and nephrectomy. The prognosis is poor regardless of therapy. Herein, we present a case with pneumocystitis. To our knowledge, there have been 54 cases previously reported. There is no doubt that emphysematous pyelonephritis with pneumocystitis as in our case is less frequent.

Application of ice water to the face in initial treatment of supraventricular tachycardia.

Supraventricular tachycardia (SVT) is a life-threatening dysrhythmia in childhood. Initial treatment includes classic vagal maneuvers, some pharmacological agents, cardioversion and application of ice water to the face. In this paper we report our results of ice water application to the face in SVT. The study included ten patients between the ages of seven days and 15 years who were admitted to our hospital with supraventricular tachycardia in the previous year. Ice water was applied to their faces for five seconds immediately and all of them were digitalized. This procedure was utilized in 28 out of 36 SVT attacks, and was found to be effective in restoring sinus rhythm on 27 of 28 occasions (96%). Tachycardia recurred a total of 18 times in three of the ten patients. There was no recurrence in six patients. No response was noted in only one patient. Application of ice water to the face is an easy, safe, effective and repeatable procedure in the initial treatment of supraventricular tachycardia.
