Can Achilles tendinosis be treated effectively with lidocaine and glucose infiltrations, and if so, is the effect lasting? A longitudinal, observational on 27 consecutive patients.

OBJECTIVE: Our aim was to add to the small but growing body of evidence on the effectiveness of ultrasound-guided Achilles intratendinous hyperosmolar dextrose prolotherapy and introduce a novel, preceding step of paratenon hydrodissection with lidocaine in patients with chronic Achilles tendinosis resistant to rehabilitation therapy. METHODS: We conducted a longitudinal, observational study on 27 consecutive patients diagnosed with Achilles tendinosis, in whom conservative treatment, ie, physiotherapy or shock wave therapy, had failed. A 2% lidocaine paratenon anesthesia and hydrodissection was followed by ultrasound-guided, intratendinous injections of 25% glucose every 5 weeks. Visual analogue scales (VAS) were used for pain assessment at rest, for activities of daily living, and after moderate exercise at the begining and at the end of the treatment. Moreover, tendon thickness and vascularisation were recorded at baseline and final treatment consultation. Effectiveness was estimated from scoring and relative pain reduction using a 95% CI. The non-parametric Wilcoxon test and a general linear model for repeated measures were applied. Statistical significance was established as p < 0.05. RESULTS: A median of 5 (1-11) injection consultations per patient were required. Pain scores decreased significantly in all three conditions (p < 0.001). Relative reductions were 75% in pain at rest (95% CI;61-93%), 69% in pain with daily living activities (95% CI; 55-83%), and 70% in pain after moderate exercise (95% CI; 57-84%). Tendon neo-vascularisation was significantly reduced (p < 0.001). We did not observe significant changes in tendon thickness (p = 0.083). CONCLUSIONS: Achilles tendinosis treatment with paratenon lidocaine hydrodissection and subsequent prolotherapy with hyperosmolar glucose solution is safe, effective, inexpensive, and virtually painless with results maintained over time.

Osificación heterotópica en paciente con SARS-CoV-2: imágenes gammagráficas y radiológicas / Heterotopic ossification in SARS-CoV-2: Scintigraphic and radiological images

Los pacientes con COVID-19 grave pueden desarrollar restricciones dolorosas del rango de movimiento de las grandes articulaciones debido a osificaciones heterotópicas. Presentamos el caso de un paciente que desarrolló dolor en las caderas después de un ingreso prolongado por neumonía COVID-19 severa. La radiografía convencional, la tomografía computarizada y la gammagrafía ósea mostraron extensas osificaciones heterotópicas en caderas. Es probable que tanto factores locales como sistémicos contribuyan al desarrollo de osificaciones heterotópicas, y es necesario descartar esta entidad cuando estos pacientes refieran dolor articular. El diagnóstico precoz es importante para proporcionar intervenciones no farmacológicas como la movilización pasiva suave y medicación antiinflamatoria y en casos refractarios considerar la resección quirúrgica del hueso ectópico.(AU)

Patients with severe COVID-19 can develop painful range-of-motion restrictions of large joints due to heterotopic ossification. We present the case of a patient who developed hip pain after prolonged admission for severe COVID-19 pneumonia. Conventional radiography, computed tomography and bone scan showed extensive heterotopic ossification in the hips. It is probable that both local and systemic factors contribute to the development of heterotopic ossifications and it is necessary to rule out this entity when these patients reported joint pain. Early diagnosis is important to provide non-pharmacological interventions such as mild passive mobilization and anti-inflammatory medication and in refractory cases surgical resection of the ectopic bone is consider.(AU)

[Transrectal biopsy scheme can predict incorrect histological grading in prostate cancer]. / El esquema de biopsia transrectal puede predecir la gradación histológica incorrecta del cáncer de próstata.

OBJECTIVE: To identify factors that might explain why a prostate with a Gleason score (GS) <7 in the biopsy specimen can turn out to have a GS ≥7 in the surgical specimen. MATERIAL AND METHODS: We compared the GS of biopsy specimens with the GS of surgical specimens in 185 patients who underwent surgery for prostate cancer. We calculated the sensitivity, specificity, and predictive values for the GS of the biopsy specimens. We used Cohen's kappa to determine the degree of concordance between a GS of <7 and ≥7 for the biopsy specimen and the surgical specimen. Age, a family history of prostate cancer, total prostate-specific antigen (tPSA), digital rectal examination, prostate structure and volume, and the number of biopsy cores (biopsy scheme) were analyzed using multivariable logistic regression. RESULTS: Histological study of biopsy specimens yielded high sensitivity (98%) but low specificity (49%) for GS ≤6 and low sensitivity (35, 26%) and high specificity (93, 99%) for GS=7 and GS ≥7, respectively. Cohen's kappa for the GS from the biopsy and surgical specimens was 0.43 (95% CI=30-56%). The biopsy scheme was the only predictor of discordance in the GS between the two techniques. Among the other variables included in the model, only tPSA showed a slightly significant association. Taking a scheme with less than 7 cores as a reference, we found no difference with 8 to 9 cores but we did find a difference with 10 to 11 cores and with 12 or more cores, with a prevalence ratio of 0.138 (95% CI=0.030-0.513) and 0.277 (95% CI=0.091-0.806), respectively. CONCLUSION: The GS of the biopsy depends on the scheme. This factor must be taken into account when choosing a treatment option in patients with low tumor grade in biopsy specimens.
