SEAT-BELT SYNDROME REVISITED

This report describes a complex syndrome of injuries occurring in a young female who was a back seat passenger wearing a lap-belt restraint in a high-speed road traffic accident. As a consequence of the forced flexion distraction injury of her lumbar spine, she sustained a fracture-subluxation of the first lumbar vertebra in association with a jejunal perforation and extensive small intestinal mesenteric laceration. She also had a large traumatic hernia of the anterior abdominal wall, which was overlooked at primary laparotomy. This report highlights collectively the classical combination of injuries associated with the lap-belt syndrome and demonstrates the importance of carefully inspecting the anterior abdominal wall for deficiencies, because traumatic herniation may be easily overlooked.     

Transfusion-related acute lung injury caused by an NB2 granulocyte- specific antibody in a patient with thrombotic thrombocytopenic purpura

HLA and granulocyte-specific antibodies have been implicated in the production of transfusion-related acute lung injury (TRALI). Reported here is a case that suggests that the patient's preexisting condition may play an important role in determining whether TRALI develops upon transfusion of blood products containing anti-white cell (WBC) antibodies. A 29-year-old woman with thrombotic thrombocytopenic purpura (TTP) underwent an uneventful 1.5-volume plasma exchange, which was followed by the transfusion of 2 red cell (RBC) units. At the end of the second RBC transfusion, the patient developed clinical signs and symptoms of noncardiogenic pulmonary edema. Serologic studies demonstrated that the serum from the second RBC donor had no HLA antibodies but did have a granulocyte-specific antibody (anti-NB2) that caused the agglutination of the recipient's granulocytes, which were NB2 positive. Serum from the donor of the first RBC unit and serum from the donors of units used in the exchange had no HLA or granulocyte-specific antibodies that reacted with the recipient's WBCs. Because the donor implicated in this reaction had a history of 21 blood donations, none of which had been associated with a transfusion reaction, we suggest that the patient's preexisting condition played a significant role in this episode of TRALI, owing to the granulocyte-specific antibody.     

Mycobacterial Infections After Renal Transplantation

Mycobacterial infections occurred in 11 of 633 (1.7 per cent)recipients of successful renal transplants. There were no casesof tuberculosis in patients receiving chemoprophylaxis, butamongst those who did not receive prophylaxis disease occurredin six of the 27 (22 per cent) high-risk patients. The majorcause of morbidity during treatment was renal allograft rejection,largely due to reduction in immunosuppressive drug therapy.     

Sutured point-fixation versus Jaboulay fixation for salvaged testicular torsion in children

BackgroundSurgical techniques for fixation of the testis are varied and subject to ongoing debate. Non-sutured techniques may avoid the theoretical morbidities of sutured fixation of the testis yet are criticized for insufficient prophylaxis against future torsion. This study aims to compare outcomes between sutured (point-fixation) versus Jaboulay fixation.MethodsEmergency scrotal explorations performed at a tertiary hospital in the state of South Australia between February 2002 and December 2017 were analyzed to identify cases of testicular torsion. Primary outcome measures included future testicular torsions and return to theater episodes following initial testicular fixation. Secondary outcome measures included re-presentations and post-operative complications.ResultsA total of 482 scrotal compartments were explored in 244 boys with acute testicular torsion. Testis fixation was performed using sutured point-fixation in 58.4% and Jaboulay tunica plication in 41.6%. No future testicular torsion occurred regardless of fixation technique. There were no significant differences in returns to theater (0.4% versus 1.2%, p = 0.12), re-presentations (6.9% versus 6.0%, p = 0.83), and post-operative complications (1.7% versus 1.8%, p = 1.0) in testes that previously underwent sutured or Jaboulay fixation, respectively.ConclusionJaboulay testicular fixation techniques are comparable with sutured point-fixation techniques in effectiveness and morbidity.Type of StudyTreatment Study.Level of EvidenceLevel III.     

Trends in treatment and overall survival among patients with proximal esophageal cancer

BACKGROUND The management of proximal esophageal cancer differs from that of tumors located in the mid and lower part of the esophagus due to the close vicinity of vital structures. Non-surgical treatment options like radiotherapy and definitive chemoradiation(CRT) have been implemented. The trends in(non-)surgical treatment and its impact on overall survival(OS) in patients with proximal esophageal cancer are unclear, related to its rare disease status. To optimize treatment strategies and counseling of patients with proximal esophageal cancer,it is therefore essential to gain more insight through real-life studies.AIM To establish trends in treatment and OS in patients with proximal esophageal cancer.METHODS In this population-based study, patients with proximal esophageal cancer diagnosed between 1989 and 2014 were identified in the Netherlands Cancer Registry. The proximal esophagus consists of the cervical esophagus and the upper thoracic section, extending to 24 cm from the incisors. Trends in radiotherapy, chemotherapy, and surgery, and OS were assessed. Analyses were stratified by presence of distant metastasis. Multivariable Cox proportional hazards regression analyses was performed to assess the effect of period of diagnosis on OS, adjusted for patient, tumor, and treatment characteristics.RESULTS In total, 2783 patients were included. Over the study period, the use of radiotherapy, resection, and CRT in non-metastatic disease changed from 53%,23%, and 1% in 1989-1994 to 21%, 9%, and 49% in 2010-2014, respectively. In metastatic disease, the use of chemotherapy and radiotherapy increased over time. Median OS of the total population increased from 7.3 mo [95% confidence interval(CI): 6.4-8.1] in 1989-1994 to 9.5 mo(95%CI: 8.1-10.8) in 2010-2014(logrank P 0.001). In non-metastatic disease, 5-year OS rates improved from 5%(95%CI: 3%-7%) in 1989-1994 to 13%(95%CI: 9%-17%) in 2010-2014(logrank P 0.001). Multivariable regression analysis demonstrated a significant treatment effect over time on survival. In metastatic disease, median OS was 3.8 mo(95%CI:2.5-5.1) in 1989-1994, and 5.1 mo(95%CI: 4.3-5.9) in 2010-2014(logrank P = 0.26).CONCLUSION OS significantly improved in non-metastatic proximal esophageal cancer, likely to be associated with an increased use of CRT. Patterns in metastatic disease did not change significantly over time.
