ABSTRACT
OBJECTIVE: To evaluate the range of motion (ROM) of the knee in patients with severe post-traumatic knee arthrofibrosis after being treated with arthroscopic fibroarthrolysis (AFA) and manipulation under anesthesia (MUA). METHODS: Case series of patients with severe post-traumatic knee arthrofibrosis who underwent AFL+MUA in a national referral center. The primary outcome to be assessed was ROM before and after surgery and then at 3-month intervals until a minimum follow-up of one year was completed. RESULTS: 51 patients were included. The main injuries preceding the stiffness were tibial plateau fracture (37.3%), distal femur fracture (27.5%), and femoral shaft fracture (15.7%). Forty-five patients had severe flexion deficits with a median preoperative flexion of 70°. Intraoperative flexion significantly improved to 110°. Significant loss of flexion was observed at 3 and 6 months, however, patients regained ROM in the 9 and 12-month follow-ups. At discharge, 80% of the patients achieved flexion of 90° or more. There were 4 intraoperative complications and 3 reinterventions were performed. CONCLUSION: AFA+MUA can help patients with severe post-traumatic knee arthrofibrosis to recover ROM in most cases. However, this procedure is not without risks and complications, therefore, careful consideration should be given to its indication and execution.
ABSTRACT
BACKGROUND AND OBJECTIVE: The use of arthroscopy for tibial plateau fractures type I, II and III according to Schatzker classification has increased, yet its employment for tibial plateau fractures Schatzker IV, V and VI is controversial due to the potential risk of compartment syndrome, deep vein thrombosis and infection. We aimed to compare the rate of operative and postoperative complications among patients with these types of tibial plateau fractures treated with and without arthroscopy at the time of definitive reduction and osteosynthesis. METHODS: Retrospective cohort study. Patients with diagnosis of tibial plateau fracture Schatzker IV, V or VI who underwent reduction and definitive osteosynthesis with or without the use of arthroscopy were included. The development of compartment syndrome, deep vein thrombosis, and fracture-related infection was evaluated up to 12 months after the definitive surgery. RESULTS: Two hundred eighty-eight patients were included: 86 with arthroscopic assistance and 202 without it. The overall complication rate in the group with and without arthroscopic assistance was 18.60% and 26.73%, respectively (P=.141). No statistical association was found between the use of arthroscopic assistance and the development of the analyzed complications. DISCUSSION AND CONCLUSION: The use of arthroscopy to support reduction or addressing concomitant intra-articular injuries did not increase the risk of complications in patients with high-energy tibial plateau fractures at 12 months of follow up.

ABSTRACT
Antecedentes y objetivo: El uso de asistencia artroscopica en fracturas de mesetas tibiales tipos I-III según la clasificación de Schatzker se ha popularizado; sin embargo aún existe controversia con respecto a su uso en fracturas Schatzker IV-VI por el potencial riesgo de complicaciones. El objetivo de este trabajo es comparar la tasa de complicaciones intra o postoperatorias entre pacientes con fracturas de mesetas tibiales de este tipo tratados con y sin artroscopia al momento de la reducción y osteosíntesis definitiva. Materiales y métodos: Estudio de cohortes retrospectivo. Se incluyeron pacientes con diagnóstico de fractura de mesetas tibiales Schatzker IV-VI, sometidos a reducción y osteosíntesis definitiva, y al manejo de lesiones asociadas con o sin el uso de artroscopia evaluando la aparición de síndrome compartimental, trombosis venosa profunda e infección relacionada a fractura con seguimiento mínimo de 12 meses posterior a la cirugía definitiva. Resultados: Se incluyeron 288 pacientes: 86 operados con asistencia artroscópica y 202 sin asistencia artroscópica. La tasa de complicaciones total en el grupo con y sin asistencia artroscópica fue del 18,60 y 26,73%, respectivamente (p=0,141). No hubo asociación estadísticamente significativa entre el uso de asistencia artroscópica y el desarrollo de las complicaciones analizadas. Discusión y conclusiones: El uso de artroscopia de rodilla como apoyo de la reducción o como adyuvancia para el tratamiento simultáneo de lesiones intraarticulares concomitantes no aumentó el riesgo de complicaciones en el postoperatorio inmediato ni tras 12 meses de seguimiento.(AU)

We report here improvements to the growth media and fermentation conditions which result in a substantial increase of Helicobacter pylori growth and in the enhanced production of vacuolating cytotoxin. Addition of glucose to the medium resulted in the increase of cell yield, cell viability and a significant improvement in the production of vacuolating cytotoxin.

The treatment of chronic arm lymphedema following axillary dissection for breast cancer is still a therapeutic challenge. To examine other treatment options, we undertook a pilot study on the efficacy of ultrasound therapy (UST) in management of these patients. Fifty patients with post-surgical arm lymphedema and without regional irradiation underwent ultrasound treatment (2 cycles at 4 month intervals) and the results were compared up to 1 year with 100 other patients treated by standardized mechanical pressure therapy (MPT) using a pneumatic pump. In this report we evaluate 96 patients who have been followed after 1 year, 31 of whom belong to UST group and 65 to the MPT group. UST did not show a statistically significant difference in whole arm reduction of lymphedema although there was initially a greater reduction in size after the first 4 months of treatment. The addition of an elastic sleeve did not improve lymphedema in either group. Advantages of UST were an overall shorter length of treatment, a tendency to greater softening of the arm, patient satisfaction by avoidance of an uncomfortable and constrictive device and better relief of osteomyofascial pain, greater scapulohumeral motion, and less intercostobrachial pain-dysesthesia.

Some results of a study done in 1975/76 in Basle are presented (N=422 people working in administrative and industrial firms). Generally medicine takers are to be found in a high percentage already in the group with little symptoms. On the other side many of those reporting a high number of symptoms do not consult a physician. The number of symptoms reported is higher with progressive age, women and lower socio-economic status. Nevertheless we do not find an increase of consultations with a physician in the same direction.

The ability to generate a number of hypotheses, so all possibilities in a situation are recognized, is a vital component in arriving at a correct nursing diagnosis. Students need learning experiences in this aspect of the diagnostic reasoning process. The authors discuss the four phase simulation method of teaching, which provides a useful model for developing beginning skills in hypothesis generation.

In order to estimate the antibody prevalence rates for Toscana virus (TOSV) among children and adults, we evaluated the seroprevalence of TOSV in a population (n = 2,737) living in Tuscany during the period of 1999 to 2006. The seroprevalence rate was 19.8% in adults and 5.8% in children, showing an age-dependent increase in TOSV-specific immunity. Meningitis due to TOSV infection was more frequent in adults than in children.

BACKGROUND: Docetaxel has a proven significant activity against breast, non-small cell lung, ovarian, head and neck, and hormone refractory prostate cancer. Preclinical pharmacokinetic studies have shown that hepatobiliary extraction is the major route of elimination. We conducted this study to elucidate the feasibility and safety of the use of docetaxel in hemodialysis patients. PATIENT AND METHODS: In a 72-year-old hormone refractory prostate cancer patient on hemodialysis for diabetic nephropathy for 3 years, a first dose (35 mg/m(2) iv) of docetaxel was completed 30 min before starting dialysis, while a second dose was administered 30 min after completion of a different hemodialysis session. Pharmacokinetic analysis was performed following both infusions. RESULTS: No apparent differences could be seen in the plasma concentration-time curves of docetaxel administered before or after dialysis. The patient experienced no significant toxicity after either administration of docetaxel. CONCLUSIONS: Docetaxel is safe in dialysis patients and does not require dose reduction. Dialysis does not remove this drug from blood.

From patient admission to discharge, pain is a critical symptom of concern to the nurse case manager. This descriptive study examined nurses' decision-making regarding pain management as documented in clinical records of patients after orthopedic surgery. Using a Nurses' Pain Management Audit Tool, data analysis revealed that during the first 24 hours after emergence from the Post-Anesthesia Care Unit, these patients received less than 50% of the narcotic doses available for their pain relief. Nurses documented less than 25% of the "ideal occurrences" possible for pain assessment, as described in the Agency for Health Care Policy and Research Guidelines. Incomplete databases for guiding patient outcomes of effective pain management were perpetuated by insufficient documentation. Nurse case managers could stimulate increased commitment and quality improvement in pain management as a crucial aspect of patient care.
