A Systematic Review: Early Simultaneous Vomer Flap with Primary Cleft Lip Repair, Does it Bring More Benefits?

INTRODUCTION: Vomer flap is a technique to close cleft lip and palate. This technique is a simple procedure that has many benefits. However, the vomer flap's application together with primary lip closure is still questionable. OBJECTIVE: To find out whether the vomer flap's application in primary cleft lip repair can provide significant benefits. DESIGN: A systematic review was conducted using the PRISMA methodology has been licensed in PROSPERO databases (CRD42023399487). SETTING: A comprehensive search was set out, utilizing eight data sources up to March 2023. PARTICIPANTS: Both cohort studies and randomized control trials regarding the use of vomer flaps performed concurrently with cleft lip repair in children up to six months old. RESULTS: This article involved 8 studies involving 542 patients who met the inclusion criteria, consisting of 6 retrospective cohort studies, 1 RCT study, and 1 prospective cohort study. Vomer flaps provide a reduction in palatal cleft distance of 3-5 mm, a relatively small number of fistulas (0-4%), improvement of velopharyngeal function (nasal tone and nasal emission), maximal development of the maxilla although it is still controversial. CONCLUSION: The vomer flap's application in primary cleft lip repair provides many advantages, such as reduced palatal and alveolar clefts, decreased risk of oronasal fistula, increased velopharyngeal function, and increased maxillary growth. It is reliable for the management of cleft lip and palate.

Myocarditis and coronavirus disease 2019 vaccination: A systematic review and meta-summary of cases.

Vaccination is significant to control, mitigate, and recover from the destructive effects of coronavirus disease 2019 (COVID-19). The incidence of myocarditis following COVID-19 vaccination has been increasing and growing public concern; however, little is known about it. This study aimed to systematically review myocarditis following COVID-19 vaccination. We included studies containing individual patient data of myocarditis following COVID-19 vaccination published between January 1, 2020 and September 7, 2022 and excluded review articles. Joanna Briggs Institute critical appraisals were used for risk of bias assessment. Descriptive and analytic statistics were performed. A total of 121 reports and 43 case series from five databases were included. We identified 396 published cases of myocarditis and observed that the majority of cases was male patients, happened following the second dose of mRNA vaccine administration, and experienced chest pain as a symptom. Previous COVID-19 infection was significantly associated (p < 0.01; OR, 5.74; 95% CI, 2.42-13.64) with the risk of myocarditis following the administration of the first dose, indicating that its primary mechanism is immune-mediated. Moreover, 63 histopathology examinations were dominated by non-infective subtypes. Electrocardiography and cardiac marker combination is a sensitive screening modality. However, cardiac magnetic resonance is a significant noninvasive examination to confirm myocarditis. Endomyocardial biopsy may be considered in confusing and severe cases. Myocarditis following COVID-19 vaccination is relatively benign, with a median length of hospitalization of 5 days, intensive care unit admission of <12%, and mortality of <2%. The majority was treated with nonsteroidal anti-inflammatory drugs, colchicine, and steroids. Surprisingly, deceased cases had characteristics of being female, older age, non-chest pain symptoms, first-dose vaccination, left ventricular ejection fraction of <30%, fulminant myocarditis, and eosinophil infiltrate histopathology.

Ozone as an adjuvant therapy for COVID-19: A systematic review and meta-analysis.

OBJECTIVE: Ozone adjuvant in COVID-19 management showed conflicting results in prior studies. Here, we aimed to comprehensively evaluate benefits and side effects of ozone as adjuvant therapy in COVID-19 patients. METHODS: Systematic searches were conducted in MEDLINE, ScienceDirect, Cochrane Library, Springer, medRxiv, and ProQuest for articles investigating ozone as adjuvant therapy in COVID-19. Clinical and laboratory outcomes, mortality, length of hospital stay, intensive care unit (ICU) admission, and adverse events were assessed. RESULTS: Thirteen studies were included in this review. Case-control studies, but not randomized controlled trials (RCTs), showed a decrease in mortality following ozone therapy (OR = 0.24 (95% CI [0.07-0.76]), p = 0.02, I2 = 0%, fixed-effect). However, ozone therapy did not improve the length of hospital stay (SMD = -0.99 (95 %CI -2.44 to 0.45), p = 0.18, I2 = 84%, random-effects) and ICU admission (RR = 0.57 (95 %CI [0.05-6.71]), I2 = 73%, p = 0.65, random-effects). Consecutive case control studies suggested that ozone therapy significantly improved levels of D-dimer (p = 0.0060), lactate dehydrogenase (LDH; p = 0.0209), C-reactive protein (CRP; p = 0.0040) and interleukin (IL)-6 (p = 0.0048) as compared to standard therapy alone. CONCLUSIONS: The beneficial effect of ozone in COVID-19 management seems to be limited to the improvements of laboratory parameters among severe patients, including the reduction of IL-6, LDH, CRP, and D-dimer levels. Meanwhile, other study endpoints, such as mortality, length of stay and ICU admission, were not improved following ozone therapy, although it may partly be due to a shorter duration of viral clearance. Furthermore, no serious adverse event was reported following ozone therapy, suggesting its high safety profile. (PROSPERO ID: CRD42021278018).

Case Report: Successful revascularization in massive pulmonary embolism with a large protruding thrombus and dilated cardiomyopathy.

Pulmonary embolism is a potentially life-threatening condition. Despite advances in diagnostics, lack of consensus and delays in determining the diagnosis of pulmonary embolism are still important problems. We report the diagnosis and management of a 37-year-old man suffering from massive pulmonary embolism, a large protruding thrombus, and dilated cardiomyopathy. Echocardiography showed dilatation of all cardiac chambers, a large protruding thrombus in the right atrium to the inferior vena cava, impaired left and right ventricular systolic function, and global hypokinetic of the left ventricle with eccentric left ventricular hypertrophy. A thoracic computerized tomography scan showed pulmonary embolism with infarction. The patient's blood pressure was 60/40 mmHg and heart rate was 110 bpm. The patient was diagnosed with high-risk acute pulmonary embolism. We gave him hemodynamic support and reperfusion therapy with a loading dose of 250,000 units of Streptokinase followed by 100,000 units/hour for 24 hours. After revascularization, the patient's hemodynamic condition improved. The diagnosis of acute pulmonary embolism is based on clinical symptoms, hemodynamic changes, or radiological examination. Unstable hemodynamic underlies high-risk stratification. Hypotension or shock results from obstruction of the pulmonary artery which causes increased right ventricular afterload and acute right ventricular dysfunction. Reperfusion with thrombolysis therapy could provide good outcomes in this patient. Prolonged anticoagulation should be given to prevent the recurrence of venous thromboembolism.
