A large mass as a sign of an infection is rare, and it might convince a physician that it had the appearance of a malignancy. The patient in this case visited our clinics after attending several hospitals, with a mass that had the appearance of a malignancy, based on the severe destructive findings observed on plain radiographs. We report the first documented case of a patient with a large mass (12×7×20 cm) and a low-grade infection, which developed at the proximal thigh after a hip arthroplasty. It is important to realize that an infection accompanied by a large mass, can mimic a highly destructive malignant lesion on plain radiographs.

The pulmonary microvasculatures of rats were studied by injection replicas prepared from Mercox. This medium enabled us to easily obtain consistent, stable, and complete injected replicas of the pulmonary vasculature. In order to investigate the three dimensional structures of the tributaries of the bronchial artery, such as the capillary plexus and vasa vasorum, we performed a scanning electron microscopic(SEM) study of the vascular casts, using Mercox CL-2B as a media. The alveolar capillaries revealed hexagonal or pentagonal rings of vascular networks. In some areas, the vascular rings composed a square network, The bronchial tree was supplied by the bronchial arteries which form a coarse capillary extending as far as the terminal bronchioles. Occasionally the capillary plexus was connected with adjacent capillary networks in and around the alveolar walls. The walls of the pulmonary artery revealed only a single layer of the vasa vasorum, but those of the pulmonary vein were surrounded by more complicated and well developed vasa vasorum than the pulmonary arterial side. The mean diameters of the venous vasa vasorum are greater than the arterial vasa vasorum.

Klinefelter's syndrome is one of the most common forms of primary hypogonadism and infertility in males. Due to increasing interest in infertility, we are encountering these patients more often. Because the reports have small numbers of patients in Korea, we made t clinical observation of 87 patients to provide references for further investigation. The chromosomal study showed 47 XXY :78 patients(89.6%), 46 XY/47 XXY,6 patients(6.9%). The 46 XY/47 XXY patients(5 cases) had larger average testicular and penile sizes than 47 XXY group(35 cases). At the first consultation 42 patients( 48.3% ) complained of small testes, while 31(35.6%) complained of infertility. Among associated diseases, 2 patients(2.3%) had endocrine disorders and 6(6.9%) had psychological disorders. The average maternal age is higher than the national average and the mean value of marital intercourses is similar. The mean height and body weight are increased and the average size of the testis and penis at relaxation are significantly decreased. The development of the body hair is poor. The average level of plasma testosterone is lower and the FSH and LH are increased significantly.

Seminal biochemical compositions are to be affected during inflammatory conditions of seminal tract such as chronic prostatitis. Especially chronic prostatitis induces changes in composition of prostatic fluid, and the chronic nature of disease also induces atrophy of prostatic secretory acini and the inflammation of seminal vesicle. We investigated the change of the seminal composition and the possible effect in sperm motility of chronic prostatitis patients. Sperm motility and seminal levels of zinc, citric acid, prostatic acid phosphatase(PAP) and fructose were measured on 12 healthy males and 21 chronic prostatitis patients. Sperm motility in chronic prostatitis patients was decreased and seminal levels of zinc, citric acid, PAP and fructose in control and chronic prostatitis patients were 143+/-10/102+/-7(ug/L), 389+/-17/293+/-25(mg/dl), 446+/-61/ 382+/-28(U/ml), 306+/-7/297+/-6(mg/dl), respectively. The change of zinc was statistically significant. In conclusion, although decrease of seminal zinc in patients with chronic prostatitis was found, there was no convincing evidence to suggest that alterations in seminal composition due to chronic prostatitis lead to decrease of sperm motility.

Inflammatory white blood cells in semen is related to semen quality affecting fertility. The role of inflammatory cells on the seminal levels of various cytokines associated with inflammation and sperm motility is evaluated. Semens from 10 healthy males and 20 chronic prostatitis patients were evaluated for the levels of interleukin(IL)-1a, IL-6, IL-8 and tumor necrosis factor(TNF)-a. Motility parameters were recorded using Hamilton-Thorne computer semen analysis system. Sperm motility parameters such as including average path velocity(VAP), straight line velocity(VSL), curvilinear velocity(VCL), lateral head displacement(ALH), beat frequency(BCF), straightness(STR), linearity(LIN), elongation and area in control and chronic prostatitis patients were 44.9+/-2.5/38.8+/-1.3(um/sec), 36.4+/-2.4/30.5+/-1.1(um/sec), 64.2+/-3.9/ 58.0+/-2.4(Fm/sec), 3.3+/-0.2/4.8+/-0.3tm), 19.8+/-3.7/13.9+/-0.3(Hz), 77.7+/-5.1/78.8+/-1.2(%), 50.6+/-17.5/53.5+/-1.9(%), 66.8+/-5.4/57.8+/-1.1(9%), 2.9+/-0.3/3.8+/-0.1(um/sec), respectively. Statistical significance was noted in VAP, VSL, ALH, BCF, elongation and area. Semen levels of IL-1a, IL-6, IL-8 and TNF-a in control and chronic prostatitis patients are 15.1+/-1.5/52.9+/-14.2 (pg/ml), 10.5+/-2.2/38.3+/-12.2 (pg/ml), 1.60+/-0.38/ 6.02+/-0.26 (ug/L), 11.8+/-2.5 / 21.7+/-4.0(pg/ml) statistically significant in all. For combined parameters, the correlation coefficient of IL-1a and VSL, ALH, Area were 0.40, 0.41, 0.37 respectively which were significant. The correlation coefficient of IL-8 and VAP, VSL, VCL, ALH, BCF, Elongation, Area were 0.48, 0.49, 0.39, 0.41, 0.55, 0.59, 0.66 respectively which were also significant. Seminal inflammatory cytokines are present in increased quantities if inflammatory white blood cells are present in semen and this increase might be related to sperm motility.

To evaluate the etiology and treatment of options in patients with hemospermia, we retrospectively reviewed 21 patients who had both transrectal ultrasound and MRI and have been followed for more than 6 months after initiation of treatment. Mean age was 40 years (range 20 - 50 years) with duration of infliction being 24 months (range 1 week to 16 years). Among the 14 patients with prostatic cyst, 9 patients underwent transurethral unroofing (TUUR) of cyst. All 9 patients were completely cured, but one patient developed postoperative epididymitis. Among the 6 patients with prostatitis, hemospermia was resolved in 4 patients after mean treatment of 12 weeks with antibiotics. In DES (Diethylstilbestrol) group, 50 % showed resolution of symptoms among 6 patients after 4 weeks of treatment, and two patients complained breast discomfort which were developed after medication. In conclusion, the antibiotic treatment is advisable in hemospermia patients with prostatitis. Prostatic cystic lesion is believed to be a factor in hemospermia, thus TUUR of cyst wall and removal of stone and hematoma in cyst can be a viable option.
