Des "psychoses affectives" aux "caractéristiques psychotiques" : les symptômes psychotiques selon le DSM, discutés à la lumière d'une série de 16 cas de dépression psychotique = From "affective psychoses" to "psychotic features": DSM's psychoticsymptoms discussed in the light of a series of 16 cases of psychoticdepression.

Objectifs. - Le DSM-5 donne une définition du symptôme psychotique indépendante de tout concept depsychose. Chez les patients dépressifs, la présence d'hallucination ou d'idée délirante, quelle que soit leurforme clinique, conduit en principe à diagnostiquer une dépression psychotique et à prescrire des neurolep-tiques. Les symptômes psychotiques sont subdivisés par le DSM en « congruents » ou « non congruents » àl'humeur. Nous discutons de la pertinence d'une catégorie de symptômes psychotiques « atypiques », peuévocateurs d'une psychose au sens classique du terme. Méthode. - Discussion de la définition opérationnelle des symptômes psychotiques du DSM, étude d'unesérie de 16 patients chez qui un diagnostic de dépression psychotique a été posé. Résultats. - Sur les 16 patients, deux seulement présentaient des symptômes psychotiques classiques, évo-cateurs d'une psychose. Chez les autres, le diagnostic reposait sur la présence de symptômes très atypiques,comme des hallucinations visuelles par exemple.

Art, història i ideologia. Programes de les cases i palaus barcelonins al segle XVIII

El fet que la pintura decorativa del darrer quart del Set-cents sigui una de les manifestacions plàstiques més interessants de la producción catalana del moment ha estat el motor impulsor de la nostra dedicació al tema dins el marc del projecte de recerca ACAF/ART. Així, centrarem la nostra ponéncia en els programes decoratius del palaus barcelonins d'aquest període.

Novel FOXF1 Mutations in Sporadic and Familial Cases of Alveolar Capillary Dysplasia with Misaligned Pulmonary Veins Imply a Role for its DNA Binding Domain.

Alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) is a rare and lethal developmental disorder of the lung defined by a constellation of characteristic histopathological features. Nonpulmonary anomalies involving organs of gastrointestinal, cardiovascular, and genitourinary systems have been identified in approximately 80% of patients with ACD/MPV. We have collected DNA and pathological samples from more than 90 infants with ACD/MPV and their family members. Since the publication of our initial report of four point mutations and 10 deletions, we have identified an additional 38 novel nonsynonymous mutations of FOXF1 (nine nonsense, seven frameshift, one inframe deletion, 20 missense, and one no stop). This report represents an up to date list of all known FOXF1 mutations to the best of our knowledge. Majority of the cases are sporadic. We report four familial cases of which three show maternal inheritance, consistent with paternal imprinting of the gene. Twenty five mutations (60%) are located within the putative DNA-binding domain, indicating its plausible role in FOXF1 function. Five mutations map to the second exon. We identified two additional genic and eight genomic deletions upstream to FOXF1. These results corroborate and extend our previous observations and further establish involvement of FOXF1 in ACD/MPV and lung organogenesis.

Automatic Comparison and Evaluation of Impressions Left by a Firearm on Fired Cartridge Cases

Recent years have been characterized by a series of publications in the field of firearms investigation questioning the reliability and objectivity of such examination. This research investigates new solutions to decrease the subjective component affecting the evaluation that follows the comparison of impressions left by a firearm on the surface of spent cartridge cases. An automatic comparison system based on 3D measurements has been developed and coupled to a bivariate evaluative model allowing assigning likelihood ratios. Based on a dataset of 79 pistols (all SIG Sauer 9 mm Luger caliber), the system shows a very high discriminating power and the LRs that it provides are very indicative of the true state under both the prosecution and the defense propositions. For example, likelihood ratios exceeding a billion are predominantly obtained when impressions originating from the same source are compared. The system is also characterized by relatively low rates (≤1%) of misleading evidence depending on the firearm considered.

Malignancy transformation of chronic osteomyelitis: description of 6 cases of Marjolin's ulcers

Marjolin's ulcer describes any malignant transformation of a chronic inflammatory lesion. In the majority of cases, a squamous cell carcinoma is diagnosed. Malignant transformation occurs usually after a long period of latency of chronic infection; it takes approximately 35 years on average. There are no typical clinical presentations, but several indirect signs may suggest the malignant transformation, such as increased or changed discharge, pathologic fracture, a slow-growing exophytic mass, or other suggestive signs of malignant transformation, which should prompt to biopsy for histological exam. The diagnosis of chronic osteomyelitis should not prevent to search for carcinoma. We present six patients with chronic osteomyelitis that developed well-differentiated squamous cell carcinoma. All patients were older than 50 years (mean 60 years, range 52-77 years). Five Marjolin's ulcers were located on the lower limb and one on the arm. The average time of the chronic discharging osteomyelitis before diagnosis of carcinoma ranged between 12 and 40 years. All patients were treated by amputation of the affected limb. None had metastasis, and one patient developed local recurrence and received palliative treatment. Our study emphasizes that Marjolin's ulcer should be considered as a rare but significant long-term complication of chronic osteomyelitis. The finding of microorganisms should not prevent from further diagnostic procedures by histopathological examination so that the correct surgical treatment can be performed.

Endoscopic repair of laryngotracheoesophageal clefts: experience in 17 cases.

OBJECTIVE: To review the presentation and evaluation of laryngotracheoesophageal clefts as well as their treatment modalities, especially endoscopic closure. STUDY DESIGN: retrospective case series. METHODS: All patients treated for laryngotracheoesophageal clefts in our clinic during the last 15 years were included. Analysis of preoperative data, surgical success and functional outcome was performed. RESULTS: A total of 18 patients were included in our study. Cleft distribution was: type I (n=1), type II (n=3), type IIIa (n=5), type IIIb (n=8) and type IVa (n=1). All clefts were closed endoscopically by CO2 laser repair except for two patients who benfited from open surgery (one type I, one type IIIb). 7 of our 18 patients (39%) experienced a complication necessitating reoperation. Surgical treatment of LTEC allowed cessation of feeding tube assistance and artificial ventilation in 47% and 42% of patients respectively. CONCLUSION: Surgical treatement of laryngotracheoesophageal clefts remains a complex procedure with a high rate of morbidity for high grade clefts. Post-surgical difficulties in feeding and breathing are associated with concomitant congenital anomalies. Endoscopic repair is a successful technique for treating up to grade IIIa laryngeal clefts. Further investigation is needed to assess the best approach for treating longer clefts.

Supernumerary molars. A review of 53 cases

Supernumerary molars are not uncommon and may be found nearly anywhere in the dental alveolar arches. A series of 36 patients that presented with 53 supernumerary molars are reviewed. They occurred more frequently in the maxilla (86.8%), had little or no clinical significance, tended to be impacted, and were not associated with the impactation of the third molar. Four cases of maxillary fifth molars are described

The Effect of Switching Ranibizumab to Aflibercept in Refractory Cases of Macular Edema Secondary to Ischemic Central Vein Occlusion.

Background: Macular edema resulting from central retinal vein occlusion is effectively treated with anti-vascular endothelial growth factor injections. However, some patients need monthly retreatment and still show frequent recurrences. The purpose of this study was to evaluate the visual and anatomic outcomes of refractory macular edema resulting from ischemic central retinal vein occlusion in patients switched from ranibizumab to aflibercept intravitreal injections. Patients and Methods: We describe a retrospective series of patients followed in the Medical Retina Unit of the Jules Gonin Eye Hospital for macular edema due to ischemic central retinal vein occlusion, refractory to monthly retreatment with ranibizumab, and changed to aflibercept. Refractory macular edema was defined as persistence of any fluid at each visit one month after last injection during at least 6 months. All patients had to have undergone pan-retinal laser scan. Results: Six patients were identified, one of whom had a very short-term follow-up (excluded from statistics). Mean age was 57 ± 12 years. The mean changes in visual acuity and central macular thickness from baseline to switch were + 20.6 ± 20.3 ETDRS letters and - 316.4 ± 276.6 µm, respectively. The additional changes from before to after the switch were + 9.2 ± 9.5 ETDRS letters and - 248.0 ± 248.7 µm, respectively. The injection intervals could often be lengthened after the switch. Conclusions: Intravitreal aflibercept seems to be a promising alternative treatment for macular edema refractory to ranibizumab in ischemic central retinal vein occlusion.

Different degrees of ischaemic injury in the right and left ventricle in cases of severe, nonfatal, pulmonary embolism.

Pulmonary fat embolism (PFE) is a common complication of blunt force traumas with bone fractures. Severe forms cause impedance to right ventricular (RV) ejection, with eventual right heart ischaemia and failure. In a prospective study, we have investigated 220 consecutive autopsy cases (73 females, 147 males, mean age 52.1 years, min 14 years, max 91 years). PFE was detected in 52 cases that were divided into three groups according to the degree of PFE (1-3). A fourth group of cases of violent death without PFE was used for comparison. In each case, histology (H&E, Masson) and immunohistochemistry (fibronectin and C5b-9) were performed on six cardiac samples (anterior, lateral and posterior wall of both ventricles). The degree of cardiac damage was registered in each sample and the mean degree of damage was calculated in each case at the RV and left ventricle (LV). Moreover, a parameter ∆ that is the difference between the mean damage at the RV and the LV was calculated in each case. The results were compared within each group and between the groups. In the present study, we could not detect prevalent RV damage in cases of high degree PFE as we did in our previous investigation. In the group PFE3 the difference of the degree of damage between the RV and LV was higher than the one observed in the groups PFE0-2 with the antibody anti-fibronectin. Prevalent right ventricular stress in cases of severe PFE may explain this observation.
