Abstract Introduction and Aim of the Study Osteoarthritis (OA) is a degenerative joint disease characterized by joint pain and progressive loss of articular cartilage. This study was conducted to evaluate the therapeutic effect of platelet-rich plasma (PRP) of the knee joint in a rat model of OA. Materials and Methods Forty adult male albino rats, weighing 200-250 gms, were used in this study, ten rats used as donors to obtain PRP. The other thirty rats were divided into two main groups. Group I: The control group (15 rats) in which the rats were subdivided into three subgroups. Subgroups IA and IB were sacrificed 4 and 6 weeks after the beginning of the experiment. Subgroup IC left for 4 weeks then received intra-articular injection of PRP in the right knee joint which was repeated three times per week for 2 weeks then the animals were sacrificed. Group II (The experimental group) (15 rats) in which OA was induced by surgical induction of cartilaginous defect in the right knee joints. The rats of group II were subdivided into three subgroups. Subgroups IIA and IIB were sacrificed 4 and 6 weeks after induction of OA respectively. Subgroup IIC received intra-articular injection of PRP (0.2 ml) in the right knee joints 4 weeks after surgery. The injection was repeated three times per week for 2 weeks then the animals were sacrificed. The right joints from all groups were collected, decalcified and processed for histological studies. Specimens were also processed for transmission electron microscopic study. Morphometric and statistical measurements were done. Results Histological examination of the right knee joints of OA (subgroups IIA and IIB) resulted in thickening of the intimal lining of the synovial membrane, cellular infiltration and increased collagen content of the subintima. The articular cartilage showed erosions, thinning of cartilage, chondrocytes and ground substance loss, and moderate expression of platelet derived growth factor (PDGF). Injection of PRP resulted in improvement of the structure of the synovial membrane and the articular cartilage and strong expression of PDGF. Conclusion Intra-articular injection of PRP resulted in a significant improvement in the histological structure of the knee joint in a rat model of OA.

Abstract Background Hoffa’s fat pad is a structure located within the fibrous joint capsule of the knee joint, but outside the synovial cavity. It plays an important biomechanical and metabolic role in knee joint, reducing the impact of forces generated by loading and producing cytokines. Changes in its size can induce modifications in the knee homeostasis. However, a great variability exists regarding its measurements. This work aims to evaluate the reliability of a measurement method of Hoffa’s fat pad dimensions through MRI. Methods 3T sagittal IW 2D TSE fat-suppressed MRI sequences, taken from the OAI (Osteoarthritis initiative) database, of 191 male and female patients, aged between 40 and 80 years, were analysed; a manual measurement of the thickness of Hoffa’s fat pad of each subject was then performed by two different readers. The interobserver reliability and intraobserver reliability of the measurements were described by coefficient of variation (CV), Pearson correlation and Bland–Altman plots. Results All statistical analyses have shown that not significant intra- or interobservers differences were evident (intraobserver CV % for the first observer was 2.17% for the right knee and 2.24% for the left knee, while for the second observer 2.31% for the right knee and 2.24% for the left knee; linear correlation was for the first observer r = 0.96 for the right knee and r = 0.96 for the left knee, while for the second observer r = 0.97 for the right knee and r = 0.96 for the left knee; in addition, the interobserver CV % was 1.25% for the right knee and 1.21% for the left knee and a high interobserver linear correlation was found: r = 0.97 for the right knee and r = 0.96 for the left knee). All results suggest that this manual measurement method of Hoffa’s fat pad thickness can be performed with satisfactory intra- and interobserver reliability. Conclusions Hoffa’s fat pad thickness can be measured, using sagittal MRI images, with this manual method that represents, for his high reliability, an effective means for the study of this anatomical structure.

Verrucous carcinoma of the scrotum is an extremely rare disease and most cases are thought to result from poor hygiene and chronic inflammation. Currently, it has not been well characterized, the etiology, diagnosis and treatment remaining poorly understood. We present the case of a 50-year-old male patient diagnosed with verrucous carcinoma of the right hemiscrotum. Wide surgical excision was performed. Favorable outcomes can be achieved by surgery, even without any adjuvant therapy, but patients should be carefully followed up.

Hereditary Leiomyomatosis

Abstract Background The objective of this study is to discuss clinical characteristics and treatments of hereditary leiomyomatosis renal cell carcinoma on the basis of 2 cases and to review recent literature, in order to present medical advances. Methods A 29-year old male patient came to our hospital because of a huge tumour on the right kidney. Enhanced CT showed that the tumour was about 15.5*10.5 cm, and was considered to be malignant. Another case was a 38-year old female patient. She complained was found to have a right kidney tumour in a routine physical examination. Enhanced CT showed an early-stage tumour of about 4.3*3.7 cm on the lower pole of the right kidney. The male patient underwent open radical nephrectomy and the female patient underwent laparoscopic radical nephrectomy and extensive retroperitoneal lymph node dissection. The two patients underwent genetic testing and were diagnosed as having hereditary leiomyomatosis with renal cell carcinoma. Results The postoperative pathology in both patients revealed type 2 papillary renal cell carcinoma but with different prognosis. The male patient suffered multiple metastasis 10 months post-operation. The metastatic tumour of the abdominal wall was resected to confirm recurrence and hereditary leiomyomatosis renal cell carcinoma was diagnosed by the genetic test. While the female patient had a specific family history and uterine leiomyomas, the genetic test helped us to identify hereditary leiomyomatosis renal cell carcinoma pre-operation. Because of the early diagnosis and timely treatment, the female patient was considered to have a good prognosis. Conclusion Hereditary leiomyomatosis renal cell carcinoma is a rare hereditary disease resulting from FH gene mutation. There are currently no effective treatments.Our cases demonstrate that hereditary leiomyomatosis renal cell carcinoma is a very aggressive disease. Early screening and surveillance are recommended for patients with a family history or who are at risk of hereditary leiomyomatosis renal cell carcinoma. Surgical and palliative therapy still play an important role in clinical treatment.
