The Mihata technique, initially developed in Japan, has shown promising long-term results. However, a standardized post-operative rehabilitation protocol for this procedure in the USA is lacking. Purpose: This study aims to evaluate the outcomes of a comprehensive rehabilitation protocol following SCR with TFL autograft in a cohort of nine patients. Participants and Methods: A prospective observational study was conducted at Concentra Urgent Care, San Francisco. Nine patients, aged 55 - 65 years, underwent SCR with TFL autograft performed by a specialized orthopedic surgeon. Post-operative rehabilitation was managed using a structured protocol, divided into three phases focusing on passive exercises, progressive range of motion, and strengthening. Outcomes were measured using the Visual Analogue Scale (VAS) for pain, forward flexion range of motion (FF-ROM), and Single Assessment Numeric Evaluation (SANE) scores over a six-month period. Results: Significant improvements were observed in pain reduction (mean VAS decrease of −3.67 points, p = 0.01), ROM (mean FF increase of 41.11 degrees, p = 0.014), and SANE scores (mean improvement of 42.11%, p = 0.009), indicating the efficacy of the rehabilitation protocol. Conclusion: The comprehensive rehabilitation protocol following SCR with TFL autograft significantly improved pain, range of motion, and shoulder function in patients, suggesting its potential utility in clinical practice.展开更多

It can mimic soft tissue sarcoma. Clinical and radiological findings may not be enough to solve the puzzle and histology remains the mainstay of diagnosis. Aim: Our aim is to highlight the unusual long interval between initial surgery and presentation of foreign body granuloma. Case Presentation: A 65-year-old man who presented 48 years after initial surgery with progressive painless fascia lata donor site soft tissue swelling. The management and histology findings were highlighted. Conclusion: The occurrence of foreign body granuloma remains an important differential following a history of past surgical procedure regardless of the time interval between the surgical procedure and the clinical presentation.展开更多

The study has employed three-dimensional surveys with laser scanning methodology and has focused both on archaeological and architectural issues. Indeed, the present layout of the basement derives from a XVII century remodelling of early Christian and medieval spaces planned by Pietro da Cortona. The architect gave a unique setting and composition to the underground spaces, different in shapes and building materials, thanks to the refinement of his baroque language. Though he worked in small spaces with static problems connected to the foundations and to the loads of the church rising above, and with poor lighting and extreme dampness, Pietro da Cortona put skilfully together “modern” elements with ancient or historical pre-existences. The study focuses on Berrettini’s design process through a three-dimensional analysis with CAD systems, starting from the new XVII century fa?ade and from the articulated distribution of routes that led to the intimate underground interiors. Metrical processing gave the possibility to improve the knowledge about room geometry and to confirm the interpretations put forward by major scholars such as Krautheimer and Cavazzi.展开更多

This is not only because of the virulence of the spirochete which causes the infection but also because of its vertical transmission rate and the potential severe adverse complications/morbidity that can result from its transmission to the fetus. Although the incidence of maternal syphilis and its fetal sequalae in low-income countries has been considerable for several years, the disease has been almost non-existent in high income countries with wide antenatal screening coverage and effective treatment programmes for Syphilis. The recent alarming increase in the incidence of maternal syphilis in high income countries has spawned a renewed public health interest in the infection, with several countries updating and strengthening public health guidance in an attempt to stem this dramatic trend. This is a short clinical update for the practising obstetrician on how to manage the antenatal patient with a positive syphilis screening test.展开更多

Surgical correction is often required in cases of severe deformity or significant functional impairment. Aim: To present the case of a patient with severe Peyronie’s disease who underwent surgical correction using an autologous fascia lata graft. Case Presentation: We report the case of a 77-year-old Black-African gentleman with Peyronie’s disease, presenting with a self-reported penile curvature of 70 degrees and significant sexual frustration. He was managed surgically with plaque excision followed by a tunica albuginea patch using a subcutaneously harvested autologous fascia lata graft, all performed in a single surgical session. Conclusion: This case highlights the importance of individualized surgical planning and patient-specific considerations in achieving optimal outcomes in the management of Peyronie’s disease, particularly in cases requiring grafting for severe curvature.展开更多
