Dedifferentiated chondrosarcoma of the ring finger: a case report of an exceptional surgical treatment and review of literature
Authors: Mani Olimpia , Andreani Lorenzo , D'Arienzo Antonio , Colangeli Simone , Capanna Rodolfo 
Published: April 2022

The DDCS is a rare, highly malignant tumor characterized by two distinct histopathologic components. The diagnosis is insidious, and the prognosis is poor. The therapy is primarily surgical. It is possible to associate chemotherapy if the nonchondrogenic component is a responder. Unfortunately, very few cases of DDCS of the hand are described in the literature. Therefore, few scientific comparisons are possible regarding diagnosis and therapy. For this reason, we decided to present a sporadic case of DDCS of the fourth finger of the left hand, presented with a seven months history of pain and swelling, which appeared after the treatment of recurrent enchondroma and was treated with amputation and complex reconstruction. To our knowledge, no similar cases have been previously reported in the literature.

Published: April 2022

Knee osteonecrosis is a debilitating progressive degenerative disease characterized by subchondral bone ischemia. It can lead to localized necrosis, tissue death, and progressive joint destruction. For this reason, it is essential to diagnose and treat this disease early to avoid subchondral collapse, chondral damage, and end-stage osteoarthritis, where the only solution is total knee arthroplasty. Three types of knee osteonecrosis have been documented in the literature: spontaneous or primitive, secondary, and post arthroscopy. Spontaneous osteonecrosis is the most common type studied in the literature. Secondary osteonecrosis of the knee is a rare disease and, unlike the spontaneous one, involves patients younger than 50 years. It presents a particular set of pathological, clinical, imaging, and progression features. The management of secondary osteonecrosis is determined by the stage of the disorder, the clinical manifestation, the size and location of the lesions, whether the involvement is unilateral or bilateral, the patient’s age, level of activity, general health, and life expectancy. This review aims to present the recent evidence on treatment options for secondary osteonecrosis of the knee, including conservative treatment, joint preserving surgery, and knee replacement.

Published: April 2022

Lateral extra-articular tenodesis (L.E.T.) have been proposed to reduce the tibia’s anterior translation and internal rotation in concomitant to Anterior cruciate ligament (A.C.L.) reconstruction. Recent studies show that the addition of L.E.T. to A.C.L. reconstruction results in a statistically significant reduction in graft failure. The purpose of the present study was to evaluate the clinical outcomes, complications, and rate of return to preinjury sports level in pediatric patients who underwent combined A.C.L. reconstruction with L.E.T. at a minimum 2-year follow-up. The authors retrospectively evaluated 42 pediatric patients at high risk of graft failure who experienced ACLR connected to L.E.T. IKDC and Tegner-Lysholm Knee Scores Scale were used to assess clinical outcomes, and the Tegner Activity Scale to evaluate the return to sport. No graft failure or subsequent surgery related to A.C.L. reconstruction occurred. Furthermore, 88% of patients returned to the sport. Satisfactory clinical results were obtained on a short and medium-term follow-up. These findings help to consider this procedure for active adolescents at a high risk of graft failure to enhance A.C.L. reconstruction.

Published: April 2022

Introduction Knee septic arthritis rapidly damages the knee joint. Gächter described a classification of joint infections based on arthroscopic findings: an arthroscopic staging of the common disease has prognostic and therapeutic consequences. The aim of this systematic review was to analyze the application of the Gächter classification system to knee septic arthritis, evaluating prognostic and therapeutic implications of this classification. Materials and Methods A comprehensive electronic search of the literature was performed. The following search terms were used: (Arthroscopy* OR Arthrotom* OR Aspiration) AND Knee AND Septic AND Arthritis. The study reported the Gächter classification in septic knee arthritis and the eradication rate according to the type. The primary endpoint is the eradication rate of septic knee arthritis according to the Gächter sort. Secondary endpoints are surgical procedures according to Gächter classification and the rate of re-operations. Results Seven studies were included. The overall eradication rate of knee septic arthritis ranged from 90% to 100%: 95%-100% Gächter I; 97%-100% Gächter II; 67%-100% Gächter III; 50%-100% Gächter IV. Surgical treatments for knee septic arthritis included arthroscopic irrigation alone, articular irrigation, and debridement in knee arthroscopy or knee arthrotomy according to Gächter stage. However, 28% required re-operations for persistent infection: secondary procedures included further irrigation and debridement with the arthroscopic or arthrotomic approach. Conclusion Gächter classification showed a crucial prognostic role in predicting the outcome of surgical treatment of septic knee arthritis. Regardless of the procedure performed, a prompt operation and an accurate debridement of the synovial membrane are the most critical factors for eradicating infection and good clinical outcomes.

Published: April 2022

Le concept de la Supply Chain 4.0 est en pleine expansion qui se réfère à l’intégration des nouvelles technologies à l’ensemble des acteurs de la Supply Chain avec l’objectif d’intégrer les flux de matières et de données pour obtenir une Supply Chain plus sûre, plus rapide et plus flexible. Cet ouvrage collectif, a un titre attrayant, est entièrement centré sur la Supply Chain 4.0. Le thème est d'une grande actualité. Bien que très intéressé par le sujet, j'ai eu un peu de mal à terminer les 281 pages car les douze chapitres de cet ouvrage manquent d’un fil directeur et la valeur ajoutée est relativement variable d’un chapitre à un autre. Cependant, cet ouvrage apporte un bon éclairage scientifique sur la façon dont certaines technologies de l'Industrie 4.0 peuvent améliorer les Supply Chains.

Published: April 2022

A pandemia trouxe diversos fatores que podem favorecer alterações na condição de saúde mental, por exemplo a desinformação ou propagação de notícias falsas, do excesso de informação, do distanciamento social e suas repercussões inclusive na empregabilidade e sustento de muitos. Dada a associação estabelecida entre o aumento da idade e mau prognóstico na COVID-19, seria sensato levantar a hipótese de que o sofrimento emocional evoluiria da mesma forma, colocando os idosos em situação de vulnerabilidade ao vírus, bem como aos efeitos psicológicos da pandemia e quarentena. No entanto, as informações sobre o impacto e o estado de saúde mental dos idosos durante o surto da COVID-19 mostram-se incipientes, e dados que abordam o impacto de epidemias anteriores nesta faixa etária também são escassos. Para atender a essa necessidade, o presente estudo foi realizado para avaliar as implicações e desafios da saúde mental do idoso. Portanto, para lidar com o envelhecimento populacional e a crescente demanda por serviços adequados existe a necessidade de qualificação dos profissionais de saúde, a implementação de uma abordagem multifacetada (equipe multidisciplinar). Tais estratégias são consideradas importantes para a manutenção da funcionalidade, preservação e melhora do desempenho cognitivo e da qualidade de vida, respeitando a singularidade de cada idoso e a atenção integral à saúde, não infringindo os princípios doutrinários do Serviço Nacional de Saúde. (SNS). Enfatiza-se ainda a necessidade de um olhar no que refere ao apoio familiar e suporte, necessitando a família, em conjunto com o idoso, refletir e discutir as estratégias necessárias.

Authors: Cunha Inês Machado , Gouveia Joana , Gomes Eva 
Published: April 2022

Background
Medically unexplained physical symptoms are a well-recognized problem and, in some cases, there is a well-established relationship between behavior and psychopathological disturbances. However, the association between drug hypersensitivity reactions and psychoactive disorders stills under discussion.

Objective
Our main goal was to establish if there is an association between self-reported drug hypersensitivity reaction and psychopathology with need for psychoactive drug consumption.

Methods
Retrospective study of adult patients evaluated in a first Immunoallergology appointment because of self-reported drug hypersensitivity over 1 year and register of data concerning psychoactive drugs use. Compare the study group with patients observed for allergic respiratory disease along the same year.

Results
The study group included 70 patients that referred a total of 92 self-reported drug hypersensitivity reactions. Twenty-nine (41.4%) were under treatment with psychoactive drugs: 20 (70%) were treated with anxiolytics, 13 (18.6%) with antidepressants, 15 (21.4%) with sedatives, and 1 (1.4%) with antipsychotics. The control group included 160 patients and 38 patients (23.8%) were under treatment with psychoactive drugs: 31 (19.4%) where treated with antidepressants, 29 (18.1%) with anxiolytics, and 3 (1.9%) with sedatives. The use of psychoactive drugs in the study group is higher than in the control group (p = 0.007), the difference is especially important for sedative drugs (p < 0.001). Besides a higher use of psychoactive drugs, the study group also has a higher frequency of use of several psychoactive drug (p = 0.002).

Conclusion
Patients with a self-report drug hypersensitivity have more tendency to be under treatment with psychoactive drugs and could have more tendency to somatization. Personality traces and psychopathology must be taken into account during an allergy workup.

Authors: Yoo Hye Won , Kim Hye-Young , Shin Kihyuk , Kim Seong Heon 
Published: April 2022

Background
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe adverse cutaneous reactions, most commonly triggered by medications, characterized by extensive necrosis and detachment of the epidermis.

Objective
We investigated the differences in clinical characteristics of drug-induced SJS/TEN depending on the type of drug in a single center.

Methods
The relevance of sex, age, culprit drugs, clinical features, courses, treatment options, and follow-up results were retrospectively evaluated in patients diagnosed with drug-induced SJS/TEN at Pusan National University Hospital between 2008 and 2019.

Results
Ninety-two patients with a mean age of 58.7 ± 20.2 years (range, 10-93 years) were included in the study. Those aged 60-80 years accounted for the largest number of patients (42.4%). Patients with drug-induced SJS/TEN comprised 40 women (43.5%) and 52 men (56.5%). We categorized drug-induced SJS/TEN cases by culprit drugs into 6 groups: antibiotics, allopurinol, antiepileptic (AED), nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen, and other drugs. The rate of NSAID-induced disease significantly increased from SJS to TEN (p = 0.016). Among the patients in the NSAID group, the proportion of TEN (40%) was higher than that in the other groups (p = 0.021). The mean body surface area was significantly lower in the AED group than in the non-AED groups (7.1 ± 9.8 vs. 23.1 ± 27.3, p = 0.020) and higher in the NSAID group than in the non-NSAID groups (47.5 ± 39.5 vs. 15.7 ± 20.0, p = 0.010).

Conclusion
This study showed that the clinical characteristics of each causative drug group may be different in drug-induced SJS/TEN. Our findings may help clinicians better understand drug-induced SJS/TEN.

Published: April 2022

Objective:
To conduct an 8-year retrospective review of a clubfoot treatment program using the Ponseti technique with close monitoring of outcomes.

Methods:
Between October 2011 and August 2019, 988 children with 1,458 idiopathic clubfeet were enrolled, ages ranging from new born up to 5 years. Ponseti treatment was used, and progress was monitored by comparing mean Pirani scores at enrollment (P1), initiation of bracing (P2), and end of treatment (P3) or most recent visit (P4) for children under treatment.

Results:
A statistically significant reduction in Pirani scores was noted (P < 0.001) for all feet. For 320 feet completing treatment (213 children), the mean Pirani scores reduced from P1: 3.8 (±1.1) to P2: 1.1 (±0.6) and finally to P3: 0.6 (±0.3). Four hundred sixteen children are currently undergoing bracing. Higher education of the head of household and male sex of the child were markedly associated with improved outcomes in foot correction status. Correction was obtained with a mean of 5.8 casts per foot, the tenotomy rate was 68.2%, and the mean duration of bracing in children completing treatment was 3.6 years (±0.9). No surgical correction, other than tenotomy, was required. Relapse was noted in 12.1% of the total enrolled feet, and 32.0% children were lost to follow-up from the entire cohort of 988 children.

Conclusion:
Clubfoot treatment requires long-term follow-up. A dedicated clubfoot program is effective in maintaining continuity of care by encouraging adherence to treatment.
