Depacked patients who underwent a shortened perihepatic packing for severe blunt liver trauma have a high survival rate: 20 years of experience in a level I trauma center

IntroductionNon-operative management is currently the preferred approach in blunt liver trauma, including high grade liver lesions. However, hemodynamic instability imposes the need for an emergency laparotomy, with a perihepatic packing (PHP) to control liver bleeding in most cases. Our retrospective study aimed to assess the outcomes of liver trauma patients who underwent a shortened PHP.MethodsAll consecutive patients who underwent PHP for blunt liver trauma from 1998 to 2019 in our Level I trauma center were included in the study. Unstable patients with severe liver trauma were transferred to the operating room without any delay, and a collective decision was made to perform abbreviated laparotomy to pack the liver. Demographics, perioperative data, postoperative outcomes, and mortality were retrospectively collected, and survivors and deceased patients were compared with a paired t-test.ResultsFifty-nine patients of 206 patients admitted with severe liver injuries were treated with shortened PHP. Thirty-four (57.6%) patients died, including 26 (76.5%) within the first 24 h. Twelve (20.3%) patients had a selective hepatic embolization and eight (13.6%) had an extrahepatic embolization. Forty-eight patients had an extra abdominal associated injury. This was not a predictive factor of mortality. The removal of packing was performed in 24 patients within 72 h after laparotomy, with an 80% survival rate in these patients.ConclusionShortened PHP is an effective strategy for controlling liver bleeding in severe hepatic trauma. The mortality rate of these patients is high, but after the removal of packing, the survival is good.     

Surgery of the spleen

The spleen is a solid organ located beneath the left hemidiaphragm. Indications for surgical resection include trauma (blunt or penetrating), haematological diseases, abscesses, hydatid disease, oncological resection or immunosuppression. Surgical approaches include open, laparoscopic and, more recently, robotic; the complications of operative intervention will also be discussed. In patients with an absent spleen there is a significant increased risk of developing overwhelming post-splenectomy infection (OPSI). It is therefore essential to protect patients from infection due to encapsulated organisms through vaccination. This requires a combination of vaccinations, antibiotic prophylaxis and good education.     

A systematic review of the safety and efficacy of non-operative management in patients with high grade liver injury

IntroductionThe liver is the most frequently damaged organ in blunt abdominal trauma. It is widely accepted that hemodynamically stable patients with low-grade liver trauma should be treated with non-operative management, however there is controversy surrounding its safety and efficacy in high-grade trauma. The purpose of this review is to investigate the role of non-operative management in patients with high-grade liver trauma.MethodsPubMed and reference lists of PubMed articles were searched to find studies that examined the efficacy of non-operative management in high-grade liver injury patients, and compare it to operative management. Non-operative management was considered successful if rescue surgery was avoided. Outcomes considered were success, mortality, and complication rates.ResultsThe electronic search revealed 2662 records, 8 of which met the inclusion criteria. All 8 studies contained results suggesting that non-operative management was safe and effective in hemodynamically stable patients with high-grade liver trauma. By combining the outcomes of the different studies, non-operative management had a high success rate of 92.4% (194/210) in high-grade liver trauma patients, which was near the overall 95.0% non-operative management success rate. Non-operative management also had mortality and complication rates of 4.6% (9/194) and 9.7% (7/72) in high-grade injury patients, respectively, compared to operative management's 17.6% (26/148) and 45.5% (5/11).ConclusionNon-operative management of liver trauma is safe and effective in hemodynamically stable patients with high-grade liver injury. It is associated with significantly lower mortality compared with operative management. More studies are required to evaluate complications of non-operative management in high-grade liver injury.     

Comparison of Salivary and Serum Alkaline Phosphates Level and Lactate Dehydrogenase Levels in Patients with Tobacco Related Oral Lesions with Healthy Subjects - A Step Towards Early Diagnosis

Aim: To evaluate and compare salivary and serum levels of Alkaline Phosphates and Lactate Dehydrogenase in patients without the habit of tobacco, in patients with the habit of tobacco, in patients with benign oral lesions and in patients with oral premalignant lesions and oral malignant lesions. Material and Methodology: This study was comprised of 500 subjects, Group I: 100 healthy individuals without the habit of tobacco usage formed the control group. Group II: 100 patients with the habit of tobacco/ smoking consumption without any oral lesion. Group III: 100 patients with benign oral lesions. Group IV: 100 patients having the history of tobacco consumption and having apparent precancerous lesions like leukoplakia, erythroplakia. Group V:100  patients having frank oral cancer. The grade of dysplasia in these patients was statically correlated with the levels of serum and salivary ALP and LDH. Results: This study revealed that there was high expression of both serum and salivary ALP and LDH  in group IV and Group V as compared with the other groups and mean difference showed a statistically significant p value of less than 0.01. This study revealed that the in group V, the highest level of serum and salivary ALP was found in those patients who were reported with poorly differentiated oral cancer. Conclusion: Both Alkaline phosphates and Lactate dehydrogenase could be considered a sensitive markers for the detection of dysplasia with already existing precancancerous and cancerous lesions.

Sleep disturbances and restless legs syndrome in postmenopausal women with early breast cancer given adjuvant aromatase inhibitor therapy

IntroductionWhether adjuvant therapy with aromatase inhibitors (AIs) causes sleep disturbances or not in postmenopausal women with early breast cancer (EBC) is still a controversial issue.MethodsBetween March 2014 and November 2017, validated questionnaires for assessing insomnia, anxiety, depression, quality of life (QoL) and restless legs syndrome (RLS) were administered to 160 EBC patients at baseline and after 3, 6, 12, and 24 months of AI therapy.ResultsAI therapy significantly decreased the patients’ QoL, but did not influence insomnia, anxiety or depression. However, it significantly increased the frequency and severity of RLS. Patients with RLS at baseline (19%) or who developed RLS during AI therapy (26.3%) reported statistically lower quality of sleep, higher anxiety and depression, and worse QoL compared to patients who never reported RLS (54.7%).ConclusionAlthough AI therapy does not affect sleep quality, it may increase RLS frequency. The presence of RLS could identify a group of EBC patients who may benefit from psychological support.     

Molecular miR-19a in Acute Myocardial Infarction: Novel Potential Indicators of Prognosis and Early Diagnosis

Objective: Due to the increasing annual incidence rate of disability and mortality in patients with acute myocardial infarction (AMI), the need for an appropriate diagnostic tool has become a crucial urgent issue. An increase in biomarkers and protein levels in response to AMI can be used as a predictive biomarker with different sensitivities and specificities. This study aimed at investigating the role of miR-19a as a biomarker with acceptable sensitivity and specificity for early diagnosis of AMI. Methods: We studied 175 patients with AMI admitted within 12 h of symptom onset and 90 healthy subjects as control group. Patients were divided into two groups, including group I (normal vessels and no significant artery stenosis) and primary percutaneous coronary intervention (PCI) group II (patients with more than 50% stenosis in vessels and severe atherosclerosis) diagnosed by angiography. The expression level of miR-19a was evaluated by the real-time polymerase chain reaction and other serum chemistries were also analyzed. Results: The results demonstrated that circulating miR-19a levels were significantly increased in patient groups compared to the control group (2.88 ± 1.06 vs. 5.93 ± 1.28, P<0.0001). We also found that miR-19a levels were higher in group II (134.62-fold) than group I (15.42-fold). The upper levels of miR-19a were significantly correlated with the increased serum levels of CK-MB (ρ=0.29, P<0.0001), CTn I (ρ=0.4, P<0.0001) and creatinine (ρ=0.27, P<0.0001). In addition, Receiver Operating Characteristic (ROC) analysis revealed that circulating miR-19a had considerable diagnostic accuracy for the patients with normal vessel with an AUC of 0.930 (95% CI: 0.697-0.765) and for PCI patients with an AUC of 0.966 (95% CI: 0.748-0.784). Conclusion: Circulating miR-19a possibly has prognostic value to be used as a promising molecular target for early diagnosis and prognosis of AMI.     

Annual Research Review: Rethinking childhood trauma-new research directions for measurement,study design and analytical strategies

Childhood trauma is a key modifiable risk factor for psychopathology. Despite significant scientific advances, traumatised children still have poorer long-term outcomes than nontraumatised children. New research paradigms are, thus, needed. To this end, the review examines three dominant assumptions about measurement, design and analytical strategies. Current research warns against using prospective and retrospective measures of childhood trauma interchangeably; against interpreting cross-sectional differences in putative mediating mechanisms between adults with or without a history of childhood trauma as evidence of longitudinal changes from pre-trauma conditions; and against directly applying explanatory models of resilience or vulnerability to psychopathology in traumatised children to forecast individual risk in unseen cases. The warnings equally apply to research on broader measures of adverse childhood experiences (ACEs). Further research examining these assumptions can generate new insights on how to prevent childhood trauma and its detrimental effects.
