Systematic Review Of Case Reports Research Articles

Understanding Creutzfeldt-Jakob disease in Iran: a systematic review of case reports.

To systematically review the reported cases of Creutzfeldt-Jakob disease (CJD) in Iran. A comprehensive literature review of CJD cases in Iran was undertaken using the PubMed®, Scopus® and Google Scholar databases. In addition, the Iranian database MagIran was searched for Persian language reports. Case selection used the following criteria: (i) patients of Iranian origin; (ii) publication in peer-reviewed journals or reputable medical databases; (iii) a definitive diagnosis of CJD based on established diagnostic criteria. Thirteen cases from twelve reports were included in this systematic review. The majority of the cases were female (11 of 13; 84.6%). The mean ± SD age of patients at hospital admission was 59.38 ± 7.44 years. The findings of the case review suggested that the prevalence of CJD in Iran is not fully established. CJD may be misdiagnosed alongside other clinical signs. The most prevalent early indications of the disease were psychiatric and neurological in nature. A considerable delay in diagnosis was observed in some cases and there was a shortage of brain autopsy records. Efforts to improve diagnostic capabilities, promote awareness and establish monitoring systems are necessary for managing the challenges of providing an early diagnosis of CJD in Iran.

The Development of Diabetes and Diabetic Ketoacidosis Following Immunotherapy Treatment: A Systematic Review of Case Reports.

As cancer continues to be the leading cause of death worldwide, additional therapeutic options other than traditional platinum-based chemotherapy have become available that target tumor cells in innovative ways. Immunotherapies (e.g., immune checkpoint inhibitors (ICI)) ramp up the immune system to target cancer cells, providing patients with more personalized and tumor cell-specific treatment options. This new age oncological treatment option has been found to provide a more meaningful and stronger alternative to traditional chemotherapy, resulting in longer periods of remission and milder side effects. However, because ICI heightens the immune system, resultant autoimmune conditions can occur. One of the most recently shown adverse effects of ICI are extreme hyperglycemia (i.e., type 1 diabetes) and diabetic ketoacidosis (DKA). To determine the incidence of immunotherapy-induced diabetes, a systematic literature review was performed using CINHAL, EBSCO, MEDLINE, and Web of Science. A total of 403 articles were initially screened, with a final 28 case reports included. The results show that checkpoint inhibitors were found to be most commonly associated with new-onset diabetes as opposed to traditional chemotherapy. Additionally, 41% of patients developed autoimmune diabetes and DKA after being placed on a single therapy of pembrolizumab (targets PD-1: programmed cell death protein 1). However, the pathological process underlying the development of endocrinopathies after treatment with ICI continues to be under investigation.

Action protocol of medical staff for airway obstruction after anterior cervical spine surgery: A systematic review of case reports

BackgroundPostoperative airway obstruction after anterior cervical spine surgery (ACSS) can be a fatal complication. Occasionally, it rapidly progresses to complete obstruction. There are no established standardized protocols on how medical staff should assess for signs and symptoms, seek help, or facilitate airway management after ACSS to prevent unfavorable events. This study aimed to primarily describe a systematic approach by assessing the signs and treatment outcomes of airway compromise in patients who underwent ACSS. Further, it recommended an action protocol after extubation for medical staff according to patients’ symptoms to prevent unfavorable outcomes. MethodsAn extensive literature search was performed on PubMed, Web of Science, and the Cochrane Library to identify case reports, case series, and cohort studies restricted to English and published between January 1990 and March 2023. We included cases that described the signs, symptoms, and treatment of airway obstruction after ACSS. Meanwhile, cases involving complications of other known causes, cases of trauma or occipital-cervical fixation, or those using bone morphogenetic protein were excluded. ResultsTwenty cases from 17 studies were obtained, and their study quality was acceptable. Four patients died, and two presented with hypoxic ischemic encephalopathy. Further, five of six patients had fatal complications that initially developed within 7 h after surgery. Then, 9 (69%) of 13 patients with evidence of hematoma (69%) showed initial symptoms within 12 h after surgery. Finally, 9 of 11 patients with early-stage symptoms had favorable outcomes, and patients who developed late-stage symptoms commonly had unfavorable outcomes. ConclusionThe early identification of signs and symptoms and immediate treatment are important, particularly within 12 h postoperatively. We suggest a novel action protocol for medical staff according to symptom urgency, which includes the measurement of neck circumference using a string for evaluating neck swelling.

Digenic Alport Syndrome in Children: A Systematic Review of Case Reports and Case Series

Background: Alport syndrome comprises inherited heterogeneous disorders involving kidneys with varying combinations of ocular pathologies and hearing loss. Digenic Alport syndrome is a pathologic variant of Alport syndrome in which there is a mutation in two out of three mutations in type IV collagen (COL4A) genes, either COL4A5 with COL4A3/COL4A4, or pathogenic variants in COL4A3 with COL4A4. There are scarce data regarding the genotype–phenotype associations in children with digenic Alport syndrome. Objective: The present systematic review focuses on clinical presentations, genetic abnormalities, pharmacological management, and associated extrarenal manifestations in digenic Alport syndrome. Methods: A comprehensive search was done in major databases, such as PubMed and Google Scholar, using defined search terms encompassing case reports or case series on digenic Alport syndrome. The identified reports underwent screening by two different authors for inclusion and exclusion criteria. Results: Thirty-three cases were included, showing that the mean age at diagnosis was 6 years. Microhematuria was the most common kidney manifestation (85%), followed by nephrotic/nephritic range proteinuria (72%), while extrarenal features were a rare finding. The main diagnostic modality was genetic testing with specific findings on electron microscopy, such as thinning of the basement membrane (76.4%). Focal segmental glomerulosclerosis was the most common finding on light microscopy (50%). A missense mutation was the most common genetic mutation present in 65.7% of cases. The patients were primarily managed with medical management initially with no data regarding follow-up. Conclusion: The digenic phenotype of Alport syndrome presents with a mean age earlier than the other variants, with hematuria and proteinuria being the most common presentations, with rare extrarenal involvements. Furthermore, the most common genetic abnormality associated with the digenic variant of Alport syndrome is a missense mutation.

Vitamin C deficiency can lead to pulmonary hypertension: a systematic review of case reports

BackgroundIn the early literature, unintentional vitamin C deficiency in humans was associated with heart failure. Experimental vitamin C deficiency in guinea pigs caused enlargement of the heart. The purpose of this study was to collect and analyze case reports on vitamin C and pulmonary hypertension.MethodsWe searched Pubmed and Scopus for case studies in which vitamin C deficiency was considered to be the cause of pulmonary hypertension. We selected reports in which pulmonary hypertension was diagnosed by echocardiography or catheterization, for any age, sex, or dosage of vitamin C. We extracted quantitative data for our analysis. We used the mean pulmonary artery pressure (mPAP) as the outcome of primary interest.ResultsWe identified 32 case reports, 21 of which were published in the last 5 years. Dyspnea was reported in 69%, edema in 53% and fatigue in 28% of the patients. Vitamin C plasma levels, measured in 27 cases, were undetectable in 24 and very low in 3 cases. Diet was poor in 30 cases and 17 cases had neuropsychiatric disorders. Right ventricular enlargement was reported in 24 cases. During periods of vitamin C deficiency, the median mPAP was 48 mmHg (range 29–77 mmHg; N = 28). After the start of vitamin C administration, the median mPAP was 20 mmHg (range 12–33 mmHg; N = 18). For the latter 18 cases, mPAP was 2.4-fold (median) higher during vitamin C deficiency. Pulmonary vascular resistance (PVR) during vitamin C deficiency was reported for 9 cases, ranging from 4.1 to 41 Wood units. PVR was 9-fold (median; N = 5) higher during vitamin C deficiency than during vitamin C administration. In 8 cases, there was direct evidence that the cases were pulmonary artery hypertension (PAH). Probably the majority of the remaining cases were also PAH.ConclusionsThe cases analyzed in our study indicate that pulmonary hypertension can be one explanation for the reported heart failure of scurvy patients in the early literature. It would seem sensible to measure plasma vitamin C levels of patients with PH and examine the effects of vitamin C administration.

Post COVID-19 vaccination medium vessel vasculitis: a systematic review of case reports.

Vaccinations are essential in minimizing the effects of global health crises including COVID-19 pandemic. This study investigates the potential association between COVID-19 vaccination and the occurrence of medium vessel vasculitis. Several databases were utilized to conduct a comprehensive literature review. Thestudies werecarefullyevaluatedtoensuretheirquality and eliminate anypotentialbias. After reviewing 935 search results and removing duplicates, we selected 10 case reports. We discovered that medium vessel vasculitis may occur after COVID-19 vaccination, typically appearing around 16.2 days after vaccination. The patients in the study had a median age of 43.5 years and were predominantly males (80%). Additionally, half of the cases were reported after the second dose of vaccination. Vaccination-associated vasculitis is a rare yet possible complication of COVID-19 vaccination and lacks a clear treatment protocol.

Adult Vitamin B12 Deficiency-Associated Pseudo-Thrombotic Microangiopathy: A Systematic Review of Case Reports.

Cobalamin-deficient thrombotic microangiopathy or vitamin B12 deficiency presenting as pseudo-thrombotic microangiopathy is a rare disorder that can be misdiagnosed as thrombotic thrombocytopenic purpura. Patients with this condition are at risk of receiving unnecessary plasmapheresis with a potential delay in appropriate therapy with vitamin B12 supplementation. There are no established diagnostic criteria for this condition in clinical practice. We performed a systematic review of case reports published between January 2018 and January 2023 to analyze the clinical characteristics, risk factors, and patterns of laboratory markers to improve the diagnostic criteria for this condition.

Features of biliary tract diseases in ketamine abusers: a systematic review of case reports

Background and aimsAnesthesiologists prefer ketamine for certain surgeries due to its effectiveness as a non-competitive inhibitor of the N-methyl-D-aspartate receptor in the brain. Recently, this agent has also shown promise as an antidepressant. However, ketamine can cause hallucinogenic effects and is sometimes abused as an illicit drug. Ketamine abuse has been associated with liver and bile duct complications. This systematic study aims to better understand cholangiopathy in ketamine abusers by reviewing case reports.Methods and materialIn this systematic review, a comprehensive literature search was conducted with the terms “biliary tract diseases” and “ketamine”. Case reports and case series of adult patients with documented ketamine abuse and reported cholangiopathy or biliary tract disease were included. We extracted the data of relevant information and the results were reported through narrative synthesis and descriptive statistics.ResultsA total of 48 studies were initially identified, and 11 studies were finally included in the review. The mean age of the patients was 25.88 years. Of the 17 patients, 64.7% were men. Symptoms often included abdominal pain, nausea, and vomiting. Most patients were discharged with improved symptoms and liver function. Common bile duct dilation and other findings were observed in imaging results and other diagnostic studies.ConclusionThis review highlights the diverse presentations and diagnostic modalities used in ketamine-induced cholangiography. These patients tend to be young men with deranged liver function tests and abdominal pain, which should be taken into consideration. These patients often require a multidisciplinary approach in their management.

Mpox reinfection: A rapid systematic review of case reports

BackgroundMpox re-emerged worldwide with the multi-country outbreaks that occurred in May 2022, threatening the public health of human beings. MethodsThis rapid systematic review summarized mpox reinfection cases documented. Electronic databases (PubMed, MedRxiv, and Social Science Research Network) were searched without time limitation, using the keywords “mpox,” “monkeypox,” & “reinfection,” “reoccur,” “reoccurrence,” “episode,” and “relapse”. All laboratory-confirmed cases of mpox reinfection published in the literature were included in this study. ResultsA total of seven publications (nine cases) from Africa, Europe, and South America were included. All mpox reinfection cases were male, with a median age of 36; 88.89% of cases had unprotected sexual behaviors with other males before each illness episode. The average onset interval between the two episodes was about 4 months. Perianal lesions and lymphadenopathy were major symptoms in both episodes, and no differences in clinical severity were reported between the two episodes. The mean duration of the two episodes was approximately 22 days and 13 days, respectively; which the mean duration of the second episode was shorter than the first infection (t = 2.17, p = 0.0487). Sexually transmitted infections were commonly concurrent among most cases, accounting for 55.6% and 77.8% in the two episodes, respectively. Full vaccination against mpox was rare among reinfection cases. ConclusionA second infection is possible even in a short period. Reinforcing monitoring, reducing high-risk behaviors, and heightening health education regarding mpox for high-risk populations are crucial to limit mpox spread, including persons with a history of mpox infection.

Pulmonary Complications of Cytomegalovirus Infection in Neonates and Infants: A Systematic Review of Case Reports and Pooled Analysis.

Cytomegalovirus (CMV) causes intrauterine infections in 0.67% of neonates, with 12.7% displaying symptoms at birth. CMV can lead to severe multiorgan involvement, and mortality in symptomatic cases is around 30%. Pulmonary complications are rare in infants with CMV. This review assesses pulmonary complications and outcomes in infants with CMV infection. A systematic literature search was conducted using PubMed, SCOPUS and Ovid SP to retrieve case reports on pulmonary complications in infants with congenital or perinatal CMV infection. Descriptive analysis and pooled analysis were conducted for the case reports. A total of 28 articles with 38 patients were included in this systematic review. The reported pulmonary complications in the case reports were CMV pneumonitis (34.2%), persistent pulmonary hypertension of the newborn (18.4%), emphysema and chronic lung disease (15.8%), diaphragmatic dysfunction (13.2%), lung cysts and calcifications (10.5%), Pneumocystis jirovecii infection (7.9%), pulmonary hypoplasia (5.3%) and bronchial atresia (2.6%). Seven (18.4%) of 38 patients passed away because of the pulmonary complications of CMV infection. Congenital transmission (P = 0.0108), maternal CMV (P = 0.0396) and presence of neonatal comorbidities (P = 0.0398) were independent risk factors for mortality. This systematic review demonstrated infrequent occurrence of severe pulmonary involvement in CMV infection but should be considered in infants with persistent or severe respiratory symptoms.

Assessing the Labeling Information on Drugs Associated With Suicide Risk: Systematic Review.

Drug-induced suicide (DIS) is a severe adverse drug reaction (ADR). Although clinical trials have provided evidence on DIS, limited investigations have been performed on rare ADRs, such as suicide. We aimed to systematically review case reports on DIS to provide evidence-based drug information. We searched PubMed to obtain case reports regarding DIS published until July 2021. Cases resulting from drugs that are no longer used or are nonapproved, substance use, and suicidal intentions were excluded. The quality of each case report was assessed using the CASE (Case Reports) checklist. We extracted data regarding demographics, medication history, suicide symptoms, and symptom improvement and evaluated the causality of DIS using the Naranjo score. Furthermore, to identify the potential suicidal risk of the unknown drugs, we compared the results of the causality assessment with those of the approved drug labels. In 83 articles, we identified 152 cases involving 61 drugs. Antidepressants were reported as the most frequent causative drugs of DIS followed by immunostimulants. The causality assessment revealed 61 cases having possible, 89 cases having probable, and 2 cases having definite relationships with DIS. For approximately 85% of suspected drugs, the risk of suicidal ADRs was indicated on the approved label; however, the approved labels for 9 drugs, including lumacaftor/ivacaftor, doxycycline, clozapine, dextromethorphan, adalimumab, infliximab, piroxicam, paclitaxel, and formoterol, did not provide information about these risks. We found several case reports involving drugs without suicide risk information on the drug label. Our findings might provide valuable insights into drugs that may cause suicidal ADRs.

Severe Early-Onset Intrahepatic Cholestasis of Pregnancy Following Ovarian Hyperstimulation Syndrome with Pulmonary Presentation after In Vitro Fertilization: Case Report and Systematic Review of Case Reports.

Intrahepatic cholestasis of pregnancy (ICP) is the most common pregnancy-related liver disease, usually presented in the third trimester with pruritus, elevated transaminase, and serum total bile acids. Evidence shows that it can be developed in the first trimester, more commonly after in vitro fertilization (IVF) procedures, with the presence of ovarian hyperstimulation syndrome (OHSS). A literature search was conducted in the PubMed/MEDLINE database of case reports/studies reporting early-onset ICP in spontaneous and IVF pregnancies published until July 2023. Thirty articles on early-onset ICP were included in the review analysis, with 19 patients who developed ICP in spontaneous pregnancy and 15 patients who developed ICP in IVF pregnancies with or without OHSS. Cases of 1st and 2nd trimester ICP in terms of "early-onset" ICP were pooled to gather additional findings. Proper monitoring should be applied even before expected pregnancy and during IVF procedures in patients with known risk factors for OHSS and ICP development (patient and family history), with proper progesterone supplementation dosage and genetic testing in case of ICP recurrence.

Acute abdomen following COVID-19 vaccination: a systematic review.

Conduct a systematic review of case reports and case series regarding the development of acute abdomen following coronavirus disease 2019 (COVID-19) vaccination, to describe the possible association and the clinical and demographic characteristics in detail. This study included case report studies and case series that focused on the development of acute abdomen following COVID-19 vaccination. Systematic review studies, literature, letters to the editor, brief comments, and so forth were excluded. PubMed, Scopus, EMBASE, and Web of Science databases were searched until June 15, 2023. The Joanna Briggs Institute tool was used to assess the risk of bias and the quality of the study. Descriptive data were presented as frequency, median, mean, and standard deviation. Seventeen clinical case studies were identified, evaluating 17 patients with acute abdomen associated with COVID-19 vaccination, which included acute appendicitis (n=3), acute pancreatitis (n=9), diverticulitis (n=1), cholecystitis (n=2), and colitis (n=2). The COVID-19 vaccine most commonly linked to acute abdomen was Pfizer-BioNTech (messenger RNA), accounting for 64.71% of cases. Acute abdomen predominantly occurred after the first vaccine dose (52.94%). All patients responded objectively to medical (88.34%) and surgical (11.76%) treatment and were discharged within a few weeks. No cases of death were reported. Acute abdomen is a rare complication of great interest in the medical and surgical practice of COVID-19 vaccination. Our study is based on a small sample of patients; therefore, it is recommended to conduct future observational studies to fully elucidate the underlying mechanisms of this association.

Clinical Features and Mutations in Children with Liddle Syndrome: A Systematic Review of Case Reports

Abstract Background: Liddle syndrome, an autosomal dominant condition, is a rare cause of hypertension, resulting from gain-of-function mutation in genes which encode the subunits of the epithelial sodium channel (ENaC). Objective: The present systematic review focuses on clinical features, genes involved, mutations, and pharmacological management. Methods: A comprehensive search was done in major databases, PubMed and Google Scholar using defined search terms encompassing case reports or case series on Liddle syndrome. The identified reports underwent screening by three different authors for inclusion and exclusion criteria. Results: In total, 44 cases were included from 35 articles. The median age of the children was 14 years, with a slightly higher proportion of males 63.63% (28/44). The most common clinical feature was hypertension (97.7%). Hypertension was controlled in all patients using ENaC channel blockers, amiloride, or triamterene. Conclusion: This is one of the first reviews collating data on Liddle syndrome. Mutations in SCNN1B were most common, with hypertension being the most consistent clinical feature.

Topical Therapies of Pyogenic Granuloma in Children: A Systematic Review of Case Reports, Case Series, and Cohort Studies

Abstract Pyogenic granuloma (PG) is a benign vascular tumor removed surgically or by physical modalities, such as electrocautery and cryotherapy. Other treatment options may be warranted, especially in children, using nonsurgical approach. The study aims to determine the effectiveness and safety of topical treatments on PG in children in the clearance of lesions. Systematic literature search were done in February 2023 in the following database: PubMed, HERDIN, Cochrane Library, Hindawi, Directory of Open Access Journals, ScienceDirect, and Google Scholar. The search included studies involving PG treated with topical medications in the pediatric age group. Twenty-five studies (9 cohort studies, 6 case series, and 10 case reports) were included and utilized the following medications: timolol, propranolol, corticosteroids, common table salt, imiquimod, and ingenol mebutate. Among the medications, timolol was the most reported drug to provide partial to complete resolution in 62 out of 149 patients. All the reviewed topical medications provided partial to complete resolution with minimal adverse effects. Among them, topical timolol, propranolol, and table salt have demonstrated high response rates. Topical therapy in children with PG may be considered as a nonsurgical option. However, further clinical trials are warranted to determine its effectiveness.

Post-operative delirium in different age groups and subtypes: a systematic review of case reports.

To explore the clinical presentations and outcomes among different ages and subtypes of post-operative delirium patients. Systematic review of Published Cases. We comprehensively searched PubMed, EMBASE, and MEDLINE for published case reports of post-operative delirium up to April 2023. The systematic review has been registered with PROSPERO. Two researchers independently conducted unblinded reviews of the full-text articles. This study included 116 patients with post-operative delirium. Compared to post-operative delirium patients aged 65 and above, those between 18 and 65 years old have lower rates of a history of hypertension, cardiovascular disease and urinary system disorder comorbidities, as well as higher usage rates of fentanyl analogs and lorazepam. Additionally, these patients exhibit lower incidences of anemia and renal failure, along with a lower mortality rate. Compared to post-operative delirium patients aged 65 and above, those under 18 years old have a higher rate of fentanyl analog usage and a higher incidence of post-operative delirium following neurological surgeries. Among the hypoactive, hyperactive, and mixed subtypes, the reasons for surgery, such as cardiovascular diseases, reproductive system diseases, and neurological disorders, significantly varied among these three subtypes. Furthermore, substance abuse history and medication usage patterns also significantly varied among these three subtypes. Our investigation has revealed noteworthy insights into post-operative delirium in different patient populations. Notably, age emerged as a pivotal factor. Compared to elderly patients (≥65 years), those aged 18 to 65 demonstrate better prognosis. Additionally, patients younger than 18 years with post-operative delirium have a higher incidence of delirium following neurosurgical procedures compared to those elderly patients. Additionally, a strong association was found between a history of substance abuse and hyperactive delirium. Variations in drug use patterns were observed across different subtypes. Importantly, post-operative delirium patients younger than 18 years, as well as those aged 18 to 65 with mixed-subtype delirium, exhibited similar high mortality rates as elderly patients. This underscores the need for increased attention to post-operative delirium patients under 65 and highlights the necessity of rapid identification and early intervention for these populations at risk of poor outcomes. https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023473383, Identifier [Registration ID: CRD 42023473383].

Human tracheal transplantation: A systematic review of case reports.

Patients with long-segment airway stenosis not amenable to conventional surgery may benefit from tracheal transplantation. However, this procedure has been only anecdotally reported, and its indications, techniques, and outcomes have not been extensively reviewed. We conducted a systematic Literature search to identify all original articles reporting attempts at tracheal transplantation in humans. Of 699 articles found by the initial search, 11 were included in the systematic review, describing 14 cases of tracheal transplantation. Patients underwent transplantation for benign stenosis in nine cases, and for malignancies in five cases. In 12 cases blood supply to the trachea was provided by wrapping the graft in a vascularized recipient's tissue, while in 2 cases the trachea was directly transplanted as a vascularized composite allograft. The transplantation procedure was aborted before orthotopic transplantation in two patients. Among the remaining 12 patients, there was 1 operative mortality, while 4 patients experienced complications. Immunosuppressants drugs were administered to the majority of patients postoperatively, and only one group of authors attempted their withdrawal, in five patients. At the end of follow-up, all 11 patients surviving the operation were alive, but 2 had a recurrent tracheal stenosis requiring an airway appliance for breathing. Human tracheal transplantation is still at an embryonic phase. Studies available in the Literature report different surgical techniques, and information on long-term outcomes is still limited. Future research is needed in order to understand the clinical value of this procedure.

Endodontic Management of Dens in Dente – A Systematic Review of Case Reports and Case Series

ABSTRACT Objective: Dens in dente is a developmental dental malformation with various anatomical traits that make treatment difficult. The importance of a timely and correct diagnosis in determining the most effective treatment approach cannot be overstated. Using three-dimensional (3D) imaging techniques has improved the diagnosis of teeth with complex anatomies, such as dens in dente. This systematic review aimed to determine the different techniques for endodontic management of teeth with Dens in dente having periapical lesions. Materials and Methods: Case reports and case series were identified in databases - PubMed-MEDLINE, Google Scholar, Research Gate, EBSCO-Host, Scopus, and Cochrane Library based on title, abstract, and full text published in the English language between January 1, 2016 and April 30, 2023. Patients who have periapical lesions and dens in dente in their permanent teeth and reporting on the results of nonsurgical or surgical intervention in terms of healing were eligible for this review, while editorial reviews, review papers, abstracts, letters to the editor, and animal studies are all excluded. Case studies on deciduous teeth, dens in dente retreatment, or dens associated with other developmental disorders are also excluded. Three authors evaluated the quality of the included studies. The quality of the included case reports and case series was evaluated using the Joanna Briggs Institute’s Critical Appraisal Checklist for Case Reports and Case Series. Results and Discussion: A total of 28 articles were suitable for inclusion, with 24 case reports and 4 case series. According to the available evidence, the condition is linked to an increased prevalence of pulp disease. Any necessary endodontic treatment may be difficult due to the aberrant anatomy. Early identification and preventive intervention rescued the teeth from further dental diseases. Conclusion: Nevertheless, thorough diagnoses and treatment planning are essential. Maintaining the vitality of the pulp or conserving the tooth using the least invasive way is the guiding principle when choosing a treatment modality. A surgical approach is only needed if the conservative approach fails. In the current systematic review, all cases showed reduction in the size of the periapical lesion or complete periapical healing.

Use of splinting in traumatized primary teeth: A systematic review of case reports

The aim of this study was to explore the use of splinting in the management of traumatized primary dentition in case reports published in the literature. Systematic searches were performed in the main health databases to identify case reports (a) with children presenting trauma in primary teeth, and (b) those that described any outcomes related to the use of splints in the management of traumatized primary teeth. The stages of study selection, data extraction and risk of bias analysis were performed. Descriptive data analysis was described. The reporting of information from this review was based on the PRISMA 2020 guidelines. Of the total number of studies initially found (n=246), eight were case reports. Outcomes of splint immobilization in primary teeth with luxation (intrusion, extrusion, and lateral displacement), intra-alveolar root fracture and/or alveolar fracture were reported. All case reports described splinting as a viable technique for immobilizing traumatized primary teeth, regardless of the type of traumatic dental injury (TDIs) and splinting technique used. Only case report verified the effectiveness of the splinting in the management of dentoalveolar trauma and demonstrated the clinical effectiveness of the contentive approach. Based on low evidence studies with a moderate risk of bias, it was observed that the use of splints for the management of alveolar bone fractures and intrusive root fractures, and in specific cases of teeth with lateral luxation, can bring additional benefits to the dento-alveolar health of traumatized primary teeth.
