Two years follow-up of patients with knee varus deformity and medial meniscus extrusion after medial opening wedge high tibial osteotomy and arthroscopic meniscus centralization.

PURPOSE: This is a retrospective study and aims to investigate the clinical outcomes of patients with knee varus deformity and extruded medial meniscus who underwent arthroscopic meniscus centralization and medial opening wedge high tibial osteotomy. METHODS: A total of 24 patients were included in the trial, and arthroscopy intraoperative photographs and standing preoperative and postoperative radiographs were taken to analyze the mechanical tibiofemoral angle and tibial plateau inclination. Postoperative complications and knee motion were recorded, and the surgical results were evaluated using the knee society score. RESULTS: The study observed four cases of surgery-related complications among all patients, but no major complications were reported. The surgery significantly improved knee flexion degrees and total knee range of motion. Satisfactory outcomes were shown in postoperative radiographs and secondary intraoperative photographs. The knee score increased from 39.6 ± 10.0 to 80.1 ± 9.0, and the functional score improved from 48.1 ± 6.9 to 89.4 ± 5.5. The preoperative tibial plateau inclination was 5.3 ± 0.7, while the postoperative data showed a decrease to 4.2 ± 0.7. The preoperative mechanical tibiofemoral angle was - 7.7 ± 1.0, and it improved in all patients postoperatively to 2.8 ± 0.9. CONCLUSION: By alternating the knee biomechanics and significantly improving symptoms and quality of life, arthroscopic medial meniscus centralization and medial open wedge high tibial osteotomy units are confirmed to be an effective alternative treatment for knee varus deformity.

[Analysis of minimally invasive treatment in the management of prostatic abscess].

OBJECTIVE: To analyze the proper time and method for treatment of prostatic abscess (PA). METHODS: This is a retrospective study that included 18 patients diagnosed with and treated for prostatic abscess between February 2017 and July 2022. After obtaining data from the patients' medical records, we analyzed their clinical features as well as the therapeutic methods opted for and their effectiveness. Results： Of the 18 patients included, one achieved a full recovery after a spontaneous rupture of the abscess. Transrectal ultrasound (TRUS)-guided aspiration was performed in the remaining 17 patients, of whom 14 had a complete resolution after this procedure whereas 3 experienced recurrence. The recurrent cases were successfully managed with transurethral (TU) de-roofing. CONCLUSION: TRUS-guided aspiration is a treatment modality with a marked curative effect for simple PAs. For refractory abscesses (recurrent, multifocal, incomplete or unsuccessful drainage) or PA located near the urethra, TU de-roofing can be considered as a first choice to shorten the course of the disease and alleviate the medical treatment expenses due to recurrence.

[An exploration on computerized examination system of dental objective structured clinical examination].

PURPOSE：In view of the present problems of clinical skill examination, in order to evaluate the candidate's clinical ability comprehensively and objectively, we constructed and implemented dental objective structured clinical examination system mainly based on computer. METHODS：This system was a multi-station examination which had 3 parts and 8 sites. The stations were composed of a variety of testing methods, including choice questions, auxiliary examinations, case analysis and basic operation skill. RESULTS: By using the computerized dental objective structured clinical examination system, we could smoothly test the ability of stomatological students in a relatively short time. The clinical ability, learning ability and professional quality could be evaluated more objectively in many ways. CONCLUSIONS：This system help students adapt to early examination of medical practitioners, improve students' clinical skills, and is worthy of wide application.

[A comparison of curative effects of percutaneous nephrostomy and open surgery in the management of postrenal acute renal failure].

OBJECTIVE: To investigate the effects and clinical value of percutaneous nephrostomy (PCN) in the management of postrenal acute renal failure (PARF). METHODS: The clinical data of 40 cases of PARF for the treatment of PCN and 20 cases with open surgery were retrospectively analyzed. RESULTS: The success rate of PCN was 100%, renal function of all patients was restored to normal range after 2-7 days of PCN, in whom 30 patients recovered. In 10 patients nephrostomy was prolonged, among them 2 patients had recurrent abdominal tumors, and 8 patients had cervical cancer in late phase. There was no death, and no complications except hematuria. In the open surgery group, renal function of 19 cases recovered to normal range after 2-7 days of drainage. Lung infection occurred in 3 patients after operation, and they recovered with antibiotic therapy. One patient died of multiple organ dysfunction failure (MOF). CONCLUSION: For PARF, PCN is preferable because of minimal trauma, less blood loss, as well as rapid recovery and better effect on recovery of renal function.

[Evaluation of absolute alcohol treatment for renal cyst with percutaneous puncture and catheterization under ultrasonographic guidance].

OBJECTIVE: To evaluate the effect of absolute alcohol treatment for renal cyst with percutaneous puncture and catheterization. METHODS: This report presented 64 cases of renal cysts, 34 cases were treated with percutaneous puncture (A group) and 30 cases with percutaneous catheterization (B group). According to the size, the cysts were divided into 2 groups, more than 6 cm in diameter and less than 6 cm in diameter. RESULTS: All the patients were followed up for 3 - 12 months by CT or B ultrasonography. Striking difference of the therapeutic results were existed when cystS were more than 6 cm in diameter. CONCLUSION: Percutaneous catheterization is applicable to the sclerosing treatment of renal cyst whose diameter is more than 6 cm.
