2.AVS(Audiovisual Stimulation)-Penogram.
Korean Journal of Urology 1988;29(3):459-469
In an effort to find more comprehensive and general diagnosis of erectile failure, we already have analysed 90 cases and reported the results. After that we added 199 more cases and performed a computer based analysis of total 289 cases in the dynamic changes of penile blood flow during natural physiologic erection after exposure to the audiovisual stimulation. The following results were obtained. 1. In normal volunteers, we were able to achieve uniform penogram findings in all cases with T.T.(Transit Time) ranging 1 to 3 minutes(mean 2.17 minutes), the EPT(Erection Persistent Time) over 30 minutes and no fluctuation phenomena after AVS. 2. Erectile failure group.(2.83 cases) (1) Group I.(108 cases; 38.2%). They demonstrated similar penogram features with the normal volunteers but EPT more than 5 minuets(mean 18.26 minutes) at least. most common causes were psychogenic origin(57 cases). (2) Group II.(175 cases ; 61.8%). Patients were showing abnormal penogram findings, and were divided into following 3 types. a) A type-Impossible type(10 cases ; 3.5%). They failed to show more than 2 fold increase in the maximal radioactivity after AVS when compared to the pre-stimuli level(mean 1.83 times). The underlying causes were identified to be arteriogenic and neurogenic. b) B type-Unstable type(124 cases ; 43.8%). They were unable to sustain erection due to fluctuation(mean 1.83 times). The underlying causes were psychogenic, vasculogenic and neurogenic origins. c) C type-Delayed type(41 cases ; 14.5%). They were showing T.T. more than 15 minutes(mean ; 23.71 minutes), and the underlying causes were arteriogenic, psychogenic and neurogenic origins. Based on these results, we have concluded that AVS-Penogram seems to the most appropriate diagnostic method for screening test and follow-up evaluation after vascular surgery. Through more clinical experience and investigation, and more comparison and analysis with other diagnostic methods, it will be a standard diagnostic approach in the future.

We report a case of kerion celsi caused by Trichophyton verrucosum in a 4-year-old male. He presented painful, tender, indurated, boggy masses discharing pus on the vertex and occiput. Kerion celsi caued by T. verrucosum was diagnosed by the characteristic gross and microscopic findings of the colony on the Sabourauds glucose. agar. The possible source of infection was searched and wq found that he raised the cattles in his house. They had multiple, scaly, whitish plaques on the skin and T. verrucosum was identified from the hairs of the lesions. He had been treated with griseofulvin and prednisolone, and all lesions were cleared leaving partial alopecia in 2 months.

SS-cream is a topical agent for treating premature ejaculation (PE) which is made with extracts from 9 natural products. We evaluated the efficacy of SS-cream in the treatment of PE. An open pilot study was performed in 186 patients with PE. The mean ejaculatory latency from intromission to ejaculation was 1.5 minutes. Sixty-four of the 186 patients (34.4%) were combined with mild erectile dysfunction in whom penile rigidity was not sufficient to be satisfied in sexual activity. Patients were instructed to apply 0.1 gm. of SS-cream on the glans penis 1 hour before sexual contact and to wash out the cream before sexual intromission. Patients were asked to complete a report form including ejaculatory latency, the degree of satisfaction in the sexual lives of both themselves and their partners, and any adverse effects after each application. One hundred and sixty-six out of 186 patients (89.2%) reported they were satisfied with the application of the SS-cream and the mean ejaculatory latency was significantly prolonged to 10.89 +/- 5.60 minutes. The mean ejaculatory latency was 9.85 +/- 3.58 minutes in 52 out of 64 patients (81.2%) with mild erectile dysfunction. There was no significant difference in the changes of ejaculatory latencies between patients with pure PE and patients with mild erectile dysfunction. Twenty patients (10.8%) claimed to have no changes of ejaculatory latencies after the application of SS-cream. Adverse effects were noted in 11 patients (5.9%), which were mild local irritation symptoms in 7 patients, and delayed ejaculation of more than 30 minutes in 4 patients, the symptoms subsided spontaneously within 4 hours. These results indicate SS-cream is effective in the treatment of PE and also PE combined with mild erectile dysfunction with a few side effects. Further studies on the action mechanisms of SS-cream and a double blind placebo-controlled trial are needed.

Hemophilia, a genetically determined disorder, can be divided into hemophilia A and hemophilia B. Hemophilia A, defined as a sex-linked recessive trait hemorrhagic disease of males characterized by a deficiency of factor VIII occurs about seven times more frequently than hemophilia B which is characterized by a deficiency of factor IX. The complications resulting from hemophilia occurs in virtually every system. This paper is concerned with a rare complication of hemophilia, iliacus hematoma with femoral neuropathy. On case of spontaneous hemorrhage of iliacus muscle with femoral neuropathy in hemophilia was decompressed through a small incision with sump drainage under cover of AHF(Anti-hemophilic factor) concentrated plasma cryoperecipitate followed AHF replacement therapy.

Dental restorative materials must have the physical properties to withstand wear and corrosion. Base metal alloys possess better mechanical properties and lower price than the gold alloys. For these reason such alloys have largely replaced the precious metal alloys. One aspect to consider is the release of metal substances to oral environment. The release of elements from dental alloys is a continuing concern because the elements may have the potentially harmful biological effects on local tissue. The purpose of this study was to minimize metal release on the nonprecious metal surfaces by ion bea assisted deposition(IBAD) of titanium nitride (TiN). Ni-Cr-Be alloys with and without TiN coatings were secured in an wear test machine opposing ruby ball to determine their relative resistance to wear with 100m, 200m, 300m and 400m sliding distance. And the corrosion behavior of the Ni-Cr-Be alloys with and without TiN coating and 3 dental noble alloys have been studied. Potentiodynamic curves were used to analyse the corrosion characteristics of the alloys. The measurement of the released Ni and Ci ions was conducted by analysis of the electrolyte solution with atomic absorption spectroscopy. The results were as follows : 1. The critical sliding distance that wore down TiN coating of 2.5micrometer thickness in this study condition was 300m. 2. Ion beam assisted deposition of TiN showed a good surface modification with respect to the properties of wear and corrosion resistance. 3. X-ray diffraction showed that the strongest peak of TiN(111) in the coatings. 4. The release of Ni and Cr ions from alloys measured by means of atomic absorption spectroscopy was reduced by ion beam assisted deposition of TiN.

Intravenous pyogenic granuloma (IVPG) is a form of pyogenic granuloma (PG) in which the capillary proliferation is confined entirely within the lumen of a vein. It occurs typically in the neck and upper extremities. Histologically, this benign lesion is similar to PG of other localizations and is characterized by a lobular proliferation of capillaries growing in a sparsely cellular, edematous collagenous stroma. We report a case of IVPG developing in the palm, an unusual site of occurrence.
