A retrospective study on the prognostic factors and success, survival, and failure outcomes of treated endodontic-periodontal lesions.

OBJECTIVES: The objective of this retrospective study was to determine possible prognostic factors of endodontic-periodontal lesions and to compare success, survival, and failure outcomes of treated endodontic-periodontal lesions across different treatment modalities, demographic variables, and anatomical tooth variations. MATERIALS AND METHODS: Data was collected from patient records in the patient management system (Salud, Titanium Solutions) from the Griffith University Dental Clinic between January 2008 and December 2021. The search strategy used the terms "endodontic periodontal lesion," "periodontal endodontic lesion," "endo perio lesion," "perio endo lesion," and "EPL." The 88 cases which met inclusion and exclusion criteria were analyzed. RESULTS: The overall success rate was 46.6%, with 21.6% of teeth surviving and 31.8% of teeth failing. Bone loss extending to the apical third (OR = 0.3, 95% CI [0.104, 0.866]), and probing depths of 5-7 mm (OR = 0.147, 95% CI [0.034, 0.633]) and 8-10 mm (OR = 0.126, 95% CI [0.029, 0.542]) were associated with a statistically significant lower odds of success (p < .05). A history of no periodontal disease (OR = 7.705, 95% CI [1.603, 37.037]) was associated with a statistically significant higher odds of success (p < .05). CONCLUSION: Practitioners should be aware of bone loss to the apical third, deep probing depths, and a history of periodontal disease as possible prognostic factors that can affect the success rate when treating endodontic-periodontal lesions. Further research with more stringent control over operator factors should be done to investigate these variables.

Induction of Repeated Social Defeat Stress in Rats.

Repeated social defeat stress (RSDS) is a model of chronic stress in rodents. There are several variants of social defeat procedures that exert robust effects in mice, but few published detailed protocols to produce a robust stress and altered immunological profile in rats. In this article, we describe the protocol for the induction of RSDS in adult male Sprague-Dawley rats. Using a resident-intruder paradigm, a physical component of stress is induced by direct attack from the resident aggressive retired breeder Long-Evans rats on the intruder experimental rats. A subsequent threat component is induced by the presence of the aggressor in the vicinity of the intruder, but with physical separation between them. The RSDS induced by this protocol produces robust immunological and behavioral changes in the experimental rats, as evidenced by development of anxiety-like behaviors in open field, social interaction, and elevated plus maze tests, as well as by changes in immune parameters (Munshi et al., 2020). This approach has been used as an ethologically relevant model of stressors that are potent enough to impact neural circuits that are similar to the neural circuits impacted in patients with depression and anxiety.

SATB2-associated syndrome: characterization of skeletal features and of bone fragility in a prospective cohort of 19 patients.

BACKGROUND: Individuals with pathogenic variants in SATB2 display intellectual disability, speech and behavioral disorders, dental abnormalities and often features of Pierre Robin sequence. SATB2 encodes a transcription factor thought to play a role in bone remodeling. The primary aim of our study was to systematically review the skeletal manifestations of SATB2-associated syndrome. For this purpose, we performed a non-interventional, multicenter cohort study, from 2017 to 2018. We included 19 patients, 9 females and 10 males ranging in age from 2 to 19 years-old. The following data were collected prospectively for each patient: clinical data, bone markers and calcium and phosphate metabolism parameters, skeletal X-rays and bone mineral density. RESULTS: Digitiform impressions were present in 8/14 patients (57%). Vertebral compression fractures affected 6/17 patients (35%). Skeletal demineralization (16/17, 94%) and cortical thinning of vertebrae (15/17) were the most frequent radiological features at the spine. Long bones were generally demineralized (18/19). The distal phalanges were short, thick and abnormally shaped. C-telopeptide (CTX) and Alkaline phosphatase levels were in the upper normal values and osteocalcin and serum procollagen type 1 amino-terminal propeptide (P1NP) were both increased. Vitamin D insufficiency was frequent (66.7%). CONCLUSION: We conclude that SATB2 pathogenic variants are responsible for skeletal demineralization and osteoporosis. We found increased levels of bone formation markers, supporting the key role of SATB2 in osteoblast differentiation. These results support the need for bone evaluation in children and adult patients with SATB2-associated syndrome (SAS).

[Assessment of a post-emergency pathway with early urological regulation]. / Analyse d'un modèle de circuit court post-urgence avec une régulation précoce urologique.

INTRODUCTION: Urological emergencies represent 7 % of the outpatients at the emergency department (ED). We assessed the effect of setting up a post-emergency consultation (CPU) after deferred urological medical regulation. METHODS: All patients admitted to the ED in a university center over the period December 2017 to July 2018 and for whom a CPU was scheduled were included. The regulation concerned the date of CPU and supplementary exams. The main outcome was the ability to provide an efficient response according to a predefined grid of specific solutions. RESULTS: One hundred and twenty-eight patients were included. The median age was 57 years (18-97). Efficacy of the CPU was 76 %. This rate was lower in no-show patients or consulting for rare and complex motives (47 %, n=60). The no-show were not reachable on the first call in 51.6 % of cases, with a similar age and motives distribution to the others. Only 6,9 % (n=128) of all consultants (n=1863) had been referred to the CPU by emergency physicians. The decision was a second consultation in 70 % (48), a new exam in 10 % (7), deferred emergency surgery in 12 % (8) and finally 18 % (12) of no follow-up. CONCLUSION: CPU following early regulation by a urologist provides an effective response in 76 % of situations. Assessment of "no-shows" helped to identify groups at risk. LEVEL OF EVIDENCE: III.

What is the distribution of Aortic Dissection Detection Risk Score in an undifferentiated emergency department chest pain population?

OBJECTIVE: To determine the distribution of Aortic Dissection Detection Risk Score (ADDRS) in undifferentiated chest pain patients. METHODS: Prospective observational study of adult patients presenting to the ED with non-traumatic chest pain. RESULTS: Of 139 patients studied, more than 75% of patients has an ADDRS ≥1, mainly because of the report of severe pain. There were no aortic dissections. In patients with non-specific chest pain, testing driven by the ADDRS protocol would have seen a 280% increase in d-dimer testing and 2200% increase in computed tomography aortogram rates. CONCLUSION: Widespread use of the ADDRS and its investigation protocol cannot be supported.

Diagnostic criteria in Pai syndrome: results of a case series and a literature review.

Pai syndrome was originally described as the association of a midline cleft lip, midline facial polyps, and lipoma of the central nervous system. However, only a few patients present with the full triad, and most exhibit a wide spectrum of phenotypic variability. The aim of this study was to phenotypically delineate Pai syndrome and to propose new criteria to facilitate a clinical diagnosis in the future. The study cohort consisted of seven case patients and an additional 60 cases diagnosed with Pai syndrome identified in a literature review. Only 23 of 67 patients presented the full triad as historically described by Pai et al. (1987). A congenital facial midline skin mass was always encountered, particularly affecting the nasal structures (60/67). A midline facial cleft was reported in 45 of 67 patients and a pericallosal lipoma in 42 of 67 patients. The proposed definition of Pai syndrome is the association of (1) a congenital nasal and/or mediofrontal skin mass and/or a mid-anterior alveolar process polyp as a mandatory criterion, and at least one of the following criteria: (2) midline cleft lip and/or midline alveolar cleft, and/or (3) a pericallosal lipoma or interhemispheric lipoma in the case of corpus callosum dysgenesis.

The association of severe encephalopathy and question mark ear is highly suggestive of loss of MEF2C function.

Auriculocondylar syndrome and isolated question mark ear result from dysregulation of the endothelin 1-endothelin receptor type A signaling pathway. Animal models have highlighted the role of the transcription factor MEF2C as an effector of this pathway. We report heterozygous MEF2C loss-of-function as a possible cause of question mark ear associated with intellectual deficiency.

Molecular, clinical and neuropsychological study in 31 patients with Kabuki syndrome and KMT2D mutations.

Kabuki syndrome (KS-OMIM 147920) is a rare developmental disease characterized by the association of multiple congenital anomalies and intellectual disability. This study aimed to investigate intellectual performance in children with KS and link the performance to several clinical features and molecular data. We recruited 31 children with KMT2D mutations who were 6 to 16 years old. They all completed the Weschler Intelligence Scale for Children, fourth edition. We calculated all indexes: the Full Scale Intellectual Quotient (FSIQ), Verbal Comprehension Index (VCI), Perceptive Reasoning Index (PRI), Processing Speed Index (PSI), and Working Memory Index (WMI). In addition, molecular data and several clinical symptoms were studied. FSIQ and VCI scores were 10 points lower for patients with a truncating mutation than other types of mutations. In addition, scores for FSIQ, VCI and PRI were lower for children with visual impairment than normal vision. We also identified a discrepancy in indexes characterized by high WMI and VCI and low PRI and PSI. We emphasize the importance of early identification and intensive care of visual disorders in patients with KS and recommend individual assessment of intellectual profile.

[Percutaneous nephrolithotomy for kidney stones in elderly patients: Meta-analysis of results and complications]. / Néphrolithotomie percutanée des calculs rénaux des personnes âgées : méta-analyse des résultats et complications.

INTRODUCTION AND OBJECTIVE: Percutaneous nephrolithotomy (PCNL) is the gold standard treatment for kidney stones regardless of age. Elderly patients (EP)≥65years old, in growing numbers, have more comorbidities than the general population, may alter results of PCNL. The aim of this meta-analysis was to compare efficacy and complications of this procedure between EP and young patients (YP). METHODS: Original studies of prospective and historical cohorts, in English or French, presenting PCNL series published on PubMed until 2015 were identified using the keywords percutaneous nephrolithotomy, elderly patients, kidney stones and staghorn calculi. Our analysis focused on therapeutic efficacy, defined by absence of residual fragment or the presence of residual fragments<4mm at 3 postoperative months, and postoperative complications according to patient age: YP<65 years old and EP≥65 years old. Binary qualitative data were analyzed using odds ratio (OR) and quantitative data by estimating the difference of means. RESULTS: In total 397 studies were identified among which 23 were checked and 8 included in the meta-analysis for methodological quality corresponding to 4995 YP and 820 EP. No efficacy difference (OR=0.96; [IC95 %: 0.80; 1.17]; P=0.71), operating time (+1.15min in EP [IC95 %: -2.83; 5.12]; P=0.57) and average length of stay (+0.29 days in EP [IC95 %: -0.14; 0.72]; P=0.19) has been reported. It was a trend to more urinary infections (OR=2.24; [IC95 %: 0.74-6.80]; P=0.16) and a significantly increase of postoperative blood transfusions in EP (OR=1.41; [IC95 %: 1.00-1.97]; P=0.04). CONCLUSIONS: PCNL for kidney stones n EP is effective with a significantly increase the risk of postoperative blood transfusions compared to YP.

Clinical reappraisal of SHORT syndrome with PIK3R1 mutations: toward recommendation for molecular testing and management.

SHORT syndrome has historically been defined by its acronym: short stature (S), hyperextensibility of joints and/or inguinal hernia (H), ocular depression (O), Rieger abnormality (R) and teething delay (T). More recently several research groups have identified PIK3R1 mutations as responsible for SHORT syndrome. Knowledge of the molecular etiology of SHORT syndrome has permitted a reassessment of the clinical phenotype. The detailed phenotypes of 32 individuals with SHORT syndrome and PIK3R1 mutation, including eight newly ascertained individuals, were studied to fully define the syndrome and the indications for PIK3R1 testing. The major features described in the SHORT acronym were not universally seen and only half (52%) had four or more of the classic features. The commonly observed clinical features of SHORT syndrome seen in the cohort included intrauterine growth restriction (IUGR) <10th percentile, postnatal growth restriction, lipoatrophy and the characteristic facial gestalt. Anterior chamber defects and insulin resistance or diabetes were also observed but were not as prevalent. The less specific, or minor features of SHORT syndrome include teething delay, thin wrinkled skin, speech delay, sensorineural deafness, hyperextensibility of joints and inguinal hernia. Given the high risk of diabetes mellitus, regular monitoring of glucose metabolism is warranted. An echocardiogram, ophthalmological and hearing assessments are also recommended.

Genetic counselling difficulties and ethical implications of incidental findings from array-CGH: a 7-year national survey.

Microarray-based comparative genomic hybridization (aCGH) is commonly used in diagnosing patients with intellectual disability (ID) with or without congenital malformation. Because aCGH interrogates with the whole genome, there is a risk of being confronted with incidental findings (IF). In order to anticipate the ethical issues of IF with the generalization of new genome-wide analysis technologies, we questioned French clinicians and cytogeneticists about the situations they have faced regarding IF from aCGH. Sixty-five IF were reported. Forty corresponded to autosomal dominant diseases with incomplete penetrance, 7 to autosomal dominant diseases with complete penetrance, 14 to X-linked diseases, and 4 were heterozygotes for autosomal recessive diseases with a high prevalence of heterozygotes in the population. Therapeutic/preventive measures or genetic counselling could be argued for all cases except four. These four IF were intentionally not returned to the patients. Clinicians reported difficulties in returning the results in 29% of the cases, mainly when the question of IF had not been anticipated. Indeed, at the time of the investigation, only 48% of the clinicians used consents mentioning the risk of IF. With the emergence of new technologies, there is a need to report such national experiences; they show the importance of pre-test information on IF.

A review of craniofacial disorders caused by spliceosomal defects.

The spliceosome is a large ribonucleoprotein complex that removes introns from pre-mRNA transcripts. Mutations in EFTUD2, encoding a component of the major spliceosome, have recently been identified as the cause of mandibulofacial dysostosis, Guion-Almeida type (MFDGA), characterized by mandibulofacial dysostosis, microcephaly, external ear malformations and intellectual disability. Mutations in several other genes involved in spliceosomal function or linked aspects of mRNA processing have also recently been identified in human disorders with specific craniofacial malformations: SF3B4 in Nager syndrome, an acrofacial dysostosis (AFD); SNRPB in cerebrocostomandibular syndrome, characterized by Robin sequence and rib defects; EIF4A3 in the AFD Richieri-Costa-Pereira syndrome, characterized by Robin sequence, median mandibular cleft and limb defects; and TXNL4A in Burn-McKeown syndrome, involving specific craniofacial dysmorphisms. Here, we review phenotypic and molecular aspects of these syndromes. Given the apparent sensitivity of craniofacial development to defects in mRNA processing, it is possible that mutations in other proteins involved in spliceosomal function will emerge in the future as causative for related human disorders.

[Elastography shows promise in testicular cancer detection]. / Apport de l'élastographie en temps réel pour la caractérisation des masses testiculaires.

PURPOSE: Elastography is a novel imaging technology that shows promise in the identification of anatomic structures. The widespread use of ultrasound for screening testicular tumors in patients with cancer risk factors highlights unclassified testicular micronodules. We investigated the ability of elastography to accurately diagnose testicular nodules. MATERIAL: Patients with clinical testicular nodules were assigned to undergo elastography in a prospective study. The imaging was carried out by a single radiologist using a static elastography unit with a 9-14MHz frequency linear transducer, to identify hardness score, loss of architecture of testicular parenchyma, and surrounding effect. When orchidectomy was required, the corresponding specimens were subjected to hematoxylin and eosin staining for histologic correlation. RESULTS: We imaged 34 testicular lesions: 26/34 (76%) malignant tumors and 8/34 (24%) non-tumor lesion including 4 hematomas, 3 orchitis and 1 ischemia. Se, Sp, PPV and NPV of hardness in elastography in differentiating between malignant and benign tissue was found to be 96.2%, 37.5%, 83%, and 75%, respectively. Further, for recognizing cancer, the loss of architecture of the testicular parenchyma detecting in elastography was 92.3%, 75%, 92.3%, and 75%, respectively, and the surrounding effect was 84.6%, 87.5%, 95.6% and 63.6%, respectively. CONCLUSION: Elastography may be a promising tool at diagnosing testicular tumor when the loss of architecture and the surrounding effect were present. Further studies are needed to evaluate whether the utility of elastography is worth pursuing to identify of unclassified testicular micronodules. LEVEL OF EVIDENCE: 3.

[RALP: comparison of the oncological and functional outcomes of the intrafascial and the interfascial approaches]. / Résultats carcinologiques et fonctionnels de l'abord interfascial de la prostatectomie robotique comparé avec l'abord intrafascial.

INTRODUCTION: Due to its technical ease and greater precision Robotic Assisted Laparoscopic radical Prostatectomy (RALP) allows a better preservation of the neurovascular bundles, thereby improving functional outcomes. The intrafascial dissection has been proposed to allow a more complete preservation of these bundles. However, this technique harbors a high rate of positive surgical margins, justifying another trend: the interfascial approach. To date, there are still few publications directly comparing these 2 techniques and our study is the first to offer a 2-year follow-up. MATERIALS AND METHODS: Our study focused on a two-hundred patients population divided into two consecutive groups. All the patients were continent preoperatively and had a satisfactory IIEF5 score: (1) Group 1 consisted of 100 patients who underwent RALP with the intrafascial approach. They had a mean age of 60.3 years (45-70). The majority of cancers were of the low or moderate risk group of d'Amico. The mean PSA was 7.43ng/ml. Seventy-five patients had a pT2, 24 a pT3 and one patient had a pT4. (2) Group 2 included 100 patients who underwent RALP with the interfascial technique. Patients had a mean age of 61.6±5.96 years (45-72), and their cancers were mostly of the low or moderate risk groups of d'Amico. The mean PSA was 6.3ng/ml. Seventy-four patients had a pT2, 22 a pT3a, and 4 had a pT3b. All patients were evaluated after one and two years of follow-up. RESULT: Rates of positive surgical margins were 45% and 19% respectively for groups 1 and 2 (P<0.0001). The rates of biochemical failure (PSA>0.2ng/ml) at 2 years were 10% and 3%, respectively for groups 1 and 2 (P=0.0447). At 2 years, 2 patients in group 1 and one patient in group 2 were using 2 or more urinary pads. Erection with or without oral medication was maintained in 65 (65%) and 31 (31%) patients respectively for groups 1 and 2 at one year. At 2 years 86 and 65 patients were having spontaneous erection, respectively in groups 1 and 2 (P=0.0006). In addition, 65 and 55 patients were also capable of sexual penetration, respectively in groups 1 and 2 (P=0.0045). CONCLUSION: The intrafascial approach exposed to a very high rate of positive surgical margins while offering only a little benefit in the erectile function preservation at 2 years compared to the interfascial variant. In our series, we did not notice any significant difference between the two techniques concerning the urinary continence. LEVEL OF EVIDENCE: 5.

[Salvage HIFU after radiotherapy and salvage radiotherapy after HIFU in locally recurrent prostate cancer: Retrospective analysis of morbidity]. / Traitements de rattrapage par HIFU après radiothérapie première et par radiothérapie après HIFU première dans la récidive locale du cancer de prostate: analyse rétrospective de la toxicité

OBJECTIVES: To evaluate the toxicity of therapeutic sequences High Intensity Focused Ultrasound (HIFU)-salvage radiotherapy (HIFU-RT) or radiotherapy-salvage HIFU (RT-HIFU) in case of locally recurrent prostate cancer. MATERIALS AND METHODS: Nineteen patients had a local recurrence of prostate cancer. Among them, 10 patients were treated by HIFU-RT and 9 patients by RT- HIFU (4 by external beam radiotherapy [EBR] and 5 by brachytherapy [BRACHY]). Urinary side effects were assessed using CTCAE v4. RESULTS: At the time of the initial management, the median age was 66.5 years (53-72), the median PSA was 10.8ng/mL (3.4-50) and the median initial Gleason score was 6.3 (5-8). Median follow-up after salvage treatment was 46.3 months (2-108). Thirty percent of the patients in the HIFU-RT group and 33.3 % of the patients in the RT-HIFU group, all belonging to the sub-group BRACHY-HIFU, had urinary complication greater than or equal to grade 2. Among all the patients, only 1 had grade 1 gastrointestinal toxicity. CONCLUSION: BRACHY-HIFU sequence seems to be purveyor of many significant urinary side effects. A larger database is needed to confirm this conclusion.

Corticosteroids in the management of brain-dead potential organ donors: a systematic review.

Summary Current guidelines recommend the administration of hormonal combination therapy including immunosuppressive doses of corticosteroids to donors with low left ventricular ejection fractions and to consider hormonal therapy administration to all donors. However, these recommendations are largely based on observational data. The aim of this systematic review (SR) was to assess the clinical efficacy and safety of corticosteroids in brain-dead potential organ donors. MEDLINE and EMBASE were searched from the earliest accessible date up to March 2013 with a qualified librarian. Studies comparing the effects of any corticosteroid with those of placebo, standard treatment, or another active comparator were sought. Two independent reviewers evaluated each citation retrieved and selected studies independently and in duplicate. A third independent reviewer resolved any disagreement. Outcomes included donor haemodynamics and oxygenation, organ procurement, recipient survival, and graft survival. This review included 11 randomized controlled trials (RCTs) and 14 observational studies. The majority used methylprednisolone and often combined it with other hormonal therapies. Ten out of the 11 RCTs yielded neutral results. However, in observational studies, use of corticosteroids generally resulted in improved donor haemodynamics and oxygenation status, increased organ procurement, and improved recipient and graft survival. Overall quality of included studies was poor, as most of them presented high risks of confounding. This SR highlights the low quality and conflicting evidence supporting the routine use of corticosteroids in the management of organ donors. A large trial evaluating the effect of corticosteroids on outcomes such as organ recovery and graft survival is warranted.
