Lateral rectus pulley concerning the orbital wall. Area of a stereotyped bony insertion.

Purpose: To examine the lateral rectus muscle pulley and its bony insertion concerning the orbital rim and periorbita. Design: Prospective. An observational anatomic study. Methods: Study population: Twenty postmortem orbits (10 right, 10 left) of 10 Caucasian cadavers (8 females, 2 males; age range at death, 57-100 years; median age, 79.5 years) fixed by the Thiel method.Intervention: The floor of the temporal fossa was exposed, and a bone window on the lateral wall of the orbit, posterior to the sphenozygomatic suture, was created, keeping the periorbita intact. The lateral canthus and lateral palpebral ligament were isolated and opened, and the eyelids were folded back. The frontozygomatic suture was identified, and the orbital septum opened adjacent to the orbital rim. The conjunctiva was opened at the limbus, and the lateral rectus insertion was isolated. The bone pillar containing the frontozygomatic suture and the insertion of the periorbita and the pulley was isolated and removed en bloc. The lateral rectus muscle was isolated and excised.Main outcome measures: Position of the pulley ring on the lateral rectus muscle belly and its bony attachment area in the lateral wall of the orbit. Results: The pulley bony attachment was roughly quadrilateral with an approximate area of 90 mm2, 3 mm (mean, range 1-5 mm) posteroinferior to the frontozygomatic suture and 1 mm posterior to the orbital rim. The anterior margin of the pulley sleeve was found at 21.0 mm (median, p25-75 20.0-22.8) from the scleral insertion. Conclusions: The lateral rectus pulley is stereotyped in its position in the muscle belly and its bony insertion, coinciding with the point of greatest adhesion of the periorbita to the anterior part of the lateral wall of the orbit.

Stereotactic anatomy of the third ventricle.

PURPOSE: Endoscopic third ventriculostomy (ETV) is a surgical procedure that can lead to complications and requires detailed preoperative planning. This study aimed to provide a more accurate understanding of the anatomy of the third ventricle and the location of important structures to improve the safety and success of ETV. METHODS: We measured the stereotactic coordinates of six points of interest relative to a predefined stereotactic reference point in 23 cadaver brain hemi-sections, 200 normal brain magnetic resonance imaging (MRI) scans, and 24 hydrocephalic brain MRI scans. The measurements were statistically analyzed, and comparisons were made. RESULTS: We found some statistically significant differences between genders in MRIs from healthy subjects. We also found statistically significant differences between MRIs from healthy subjects and both cadaver brains and MRIs with hydrocephalus, though their magnitude is very small and not clinically relevant. Some stereotactic points were more posteriorly and inferiorly located in cadaver brains, particularly the infundibular recess and the basilar artery. It was found that all stereotactic points studied were more posteriorly located in brains with hydrocephalus. CONCLUSION: The study describes periventricular structures in cadaver brains and MRI scans from healthy and hydrocephalic subjects, which can guide neurosurgeons in planning surgical approaches to the third ventricle. Overall, the study contributes to understanding ETV and provides insights for improving its safety and efficacy. The findings also support that practicing on cadaveric brains can still provide valuable information and is valid for study and training of neurosurgeons unfamiliar with the ETV technique.

Gluteoplasty With Lumbar Gluteal Flap Associated With Liposuction and Fat Grafting: A Safe Technique for Massive Weight Loss Patients.

BACKGROUND: Weight loss leads to excessive flaccidity, volume loss, and tissue descent in the gluteal region. Translated autologous flaps during lower body lifting have been utilized in patients; they address sagging tissue and the lack of volume. However, sometimes use of these autologous flaps does not provide adequate gluteal projection, and a second procedure with fat injection may be required. OBJECTIVES: The authors describe their technique of a lower body lift with a lumbosacral flap in association with liposuction and lipofilling for gluteoplasty. METHODS: A prospective series of 23 post-bariatric surgery individuals who underwent a lower body lift with lumbosacral flap gluteal augmentation, liposuction, and lipofilling between January 2021 and September 2022 were described. The satisfaction rate and complications were assessed 6 months postoperatively with a validated questionnaire (BODY-Q scale). RESULTS: The patients had a mean age of 38.18 (range, 28-56 years) and median body mass index of 26. Four patients with dehiscence were diagnosed and treated conservatively. All wound breakdowns were observed in the paramedian plane of the torsoplasty. No reoperations were performed. The mean satisfaction percentage of the BODY-Q scale transformed score was 97.5. CONCLUSIONS: A technique for a lower body lift with buttock augmentation combined with liposuction and fat grafting was presented. In future studies other techniques to maximize gluteal contouring should be investigated.

What to expect from primary inferior oblique overaction after esotropia surgery : Primary inferior oblique overaction in esotropia.

BACKGROUND: Overelevation in adduction is common in patients with primary esotropia. This study evaluates the variation in ocular motility pattern in patients with primary inferior oblique (IO) muscle overaction after esotropia surgery. METHODS: The medical records of consecutive patients who underwent surgery for infantile, partially accommodative, and basic esotropia over eleven years and had at least one year of follow-up were reviewed. Patients with primary inferior oblique muscle overaction (IOOA) presented at baseline or during follow-up were selected and divided according to the first surgery performed concurrently with horizontal rectus surgery: without IO recession (NO-recess), with unilateral IO recession (UNIL-recess), and with bilateral IO recession (BIL-recess). The success (version normalisation or at least 2 points upgrade in severity scale [0-4] in the operated eye), recurrence rates, and the evolution of the non-operated IO muscles were evaluated. RESULTS: One hundred and ten patients were included - 53 NO-recess, 26 UNIL-recess, and 31 BIL-recess. Medial rectus muscle posterior fixation sutures surgery (PFS) was performed in 88.2% of patients for esotropia. A recession with graded anterior transposition was the weakening IO procedure. In the NO-recess group, 28 (52.8%) patients normalised their mild IOOA after PFS surgery alone. In the UNI-recess group, the success rate was 88.5%, with 16 (61.5%) patients showing worsened IO muscle of the fellow eye, which prompted additional surgery in 10 patients. In the BIL-recess group, all 31 patients improved the adduction pattern of the operated eye for an 80.6% success rate (6 improved marginally). CONCLUSION: Graded anterior transposition of the inferior oblique muscle effectively normalises versions. However, it's frequent for a contralateral overaction to become manifest after unilateral IO surgery.

Retalho supraclavicular para reconstrução oncológica em cabeça e pescoço: Uma série de 62 casos / Supraclavicular flap for head and neck oncological reconstruction: A series of 62 cases

Introdução: A reconstrução oncológica de defeitos extensos em cabeça e pescoço impõe ao cirurgião plástico a difícil decisão entre o uso de retalhos livres e retalhos pediculados. O retalho supraclavicular é um dos principais exemplos de retalho pediculado, sendo versátil, com espessura delgada e cor semelhante à região a ser reconstruída. Método: Um estudo retrospectivo foi realizado através da coleta de dados de prontuário de pacientes internados no Instituto do Câncer do Estado de São Paulo, entre dezembro de 2010 e março de 2020. Resultados: Dentre os 62 pacientes reconstruídos com retalho supraclavicular, 37 eram do sexo masculino e 25 do sexo feminino. Cinquenta e oito pacientes (93,5%) possuíam alguma comorbidade associada. Ao todo, 27 complicações relacionadas ao retalho (43,5%) foram registradas, sendo 5 necroses totais (8%). Conclusão: O retalho supraclavicular possui importante papel nas reconstruções oncológicas de cabeça e pescoço e deve ser considerado como opção em pacientes maus candidatos a retalhos microcirúrgicos.

Introduction: The oncological reconstruction of extensive defects in the head and neck requires the plastic surgeon to make a difficult decision between the use of free flaps and pedicled flaps. The supraclavicular flap is one of the main examples of a pedicled flap, being versatile, with a thin thickness and similar color to the region to be reconstructed. Method: A retrospective study was carried out by collecting data from medical records of patients admitted to the Cancer Institute of the State of São Paulo between December 2010 and March 2020. Results: Among the 62 patients reconstructed with a supraclavicular flap, 37 were male and 25 female. Fifty-eight patients (93.5%) had some associated comorbidity. In total, 27 complications related to the flap (43.5%) were recorded, 5 of which were total necrosis (8%). Conclusion: The supraclavicular flap plays an important role in head and neck oncological reconstructions and should be considered as an option in patients who are poor candidates for microsurgical flaps.

Revisiting Posterior Fixation Sutures Surgery: Unveiling Novel Approaches for Primary Management of Diverse Esotropia Cases.

INTRODUCTION: Strabismus, specifically esotropia, presents a significant challenge in ophthalmic surgery, while several treatment options exist. This study aims to evaluate the results of posterior fixation sutures (PFS) on the medial rectus as a primary approach for some types of esotropia. METHODS: The medical records of consecutive patients who underwent surgery for esotropia over 11 years and had at least 1 year of follow-up were reviewed retrospectively. Patients were classified into one of three types of deviation: infantile (IE), partially accommodative (PAE) and basic (BE) esotropias. An alignment within 16 prism diopters (PD) of orthotropia was a successful outcome. RESULTS: A total of 404 patients were included: 67 IE, 180 PAE and 157 BE. Before surgery, a deviation greater than 30 PD was present in 88.1% and 80.1%, and a deviation greater than 50 PD was present in 66.5% and 52.9% of patients (near and distance, respectively). In the BE group, PFS was the baseline surgery in a smaller number of cases (75%) compared to the other two groups (versus 86.6% [IE] and 88.3% [PAE], p = 0.002). The need for an additional procedure was significantly higher in the infantile esotropia group (44.8% vs. 18.9% and 24.8%, p < 0.001). Final surgical success was achieved in 95.3% of all patients. Orthotropia was achieved in 19.4% (IE), 29.6% (PAE) and 25.5% (BE) of cases. CONCLUSION: PFS of the medial rectus without recession proved successful as a first-line procedure for esotropia in the subtypes of patients evaluated in this study.

Superior Gluteal Nerve Anatomy and Its Injuries: Aiming for a More Secure Surgical Approach of the Pelvic Region.

Because most of the recognized causes of superior gluteal nerve (SGN) injury are iatrogenic, detailed knowledge of the anatomy of the SGN is crucial to prevent its injury associated with surgical procedures. This study aims to describe the precise location of SGN or its branches at the greater sciatic foramen, measure the distances of these neural structures to palpable bony landmarks, and evaluate the possible correlation between these parameters and pelvis size. Twenty human cadaveric hemipelvises were studied. After dissection to expose the SGN or its branches at the greater sciatic foramen, the distances from these neural structures to the greater trochanter (GT), to the anterior superior iliac spine (ASIS), to the posterior superior iliac spine (PSIS), to the ischial tuberosity (IT), and to the greater sciatic notch apex were measured. We found that at the greater sciatic foramen, the SGN emerges as a common trunk in 75% of hemipelvises, and already divided in its superior and inferior branches in 25% of hemipelvises. When the SGN exits the pelvis as a common trunk, it does so, in most cases, in contact with the bone at the apex of the greater sciatic notch or superior to the level of the apex. The median distance from the SGN at the greater sciatic notch to the PSIS, ASIS, GT and IT is 7.6 cm, 10.9 cm, 7.5 cm and 10.8 cm, respectively. We found a positive correlation between some of the analyzed parameters and the size of the pelvis. The anatomical data of this study may serve as pivotal guides during orthopedic pelvic surgery, contributing to minimize SNG iatrogenic lesions with significant implications in the patient's quality of life.

Automated macular segmentation can distinguish glaucomatous from compressive optic neuropathy.

PURPOSE: To compare macular damage in glaucomatous optic neuropathy (GON) and compressive optic neuropathy (CON) and assess its diagnostic accuracy in distinguishing between diseases. METHODS: Observational, cross-sectional, single-center study. Patients with GON, CON, and healthy controls were included according to the eligibility criteria. An automated spectral-domain optical coherence tomography (SD-OCT) algorithm was used to segment the circumpapilary retinal nerve fiber layer (cpRNFL) and macula. The layer thickness was measured in each sector according to the Early Treatment Diabetic Retinopathy Study and the 6-sector Garway-Heath-based grids. Data was compared across all study groups, and the significance level was set at 0.05. RESULTS: Seventy-five eyes of 75 participants, 25 with GON, 25 with CON, and 25 healthy controls (CG), were included. Macular thickness was diminished in the ganglion cell complex of GON and CON patients compared to CG (p<0.05). The best Garway-Heath-based grid parameters for distinguishing GON and CON were the nasal-inferior (NI) and nasal-superior sectors and the NI/temporal inferior (TI) damage ratios in the macular ganglion cell (mGCL) and inner plexiform (IPL) layers. Moreover, the combination of the NI sector and NI/TI damage ratios in both layers had higher discriminative power (AUC 0.909; 95% CI 0.830-0.988; p<0.001) than combining parameters in each layer separately. CONCLUSION: Our findings suggest that the evaluation of macular segmented layers damage by SD-OCT may be a helpful add-on tool in the differential diagnosis between GON and CON.

Venous malformations: what do phleboliths tell us in the pediatric population?

PURPOSE: Phleboliths are often observed within Venous malformations (VM) and frequently indicated as cause of morbidity. The aim of this study is to investigate independent risk factors for phleboliths in a pediatric population and to determine if its presence influences clinical management. METHODS: We retrospectively review data from patients diagnosed with VM in a vascular anomalies center during a 5-year period. Associations between phleboliths and potential risk factors were assessed. A multivariable analysis, was performed to assess the influence of phleboliths in the need for surgery. RESULTS: We included 88 patients with a mean age of 10 years. Phleboliths were found in 33.0%. In univariate analysis, there were no significant differences between the two groups regarding age or gender, location, dimension or depth of the VM, pain and laboratory parameters. Multivariable analysis could not detect any independent risk factor for phleboliths. In contrast, multivariable logistic analysis revealed that when phleboliths were present, the need for surgical extirpation was more likely (p = 0.031). CONCLUSIONS: This study showed that patients who have phleboliths within their VM seem to require surgery more frequently. This constitutes an entirely innovative thought that could raise awareness to a lower threshold for surgery in this group of patients.

Medical Photography Usage Amongst Doctors at a Portuguese Hospital.

Technological advancements in smartphones have made it possible to create high-quality medical photographs, with the potential to revolutionise patient care. To ensure the security of the patient's data, it is important that medical professionals receive informed consent from the patient, that physical conditions are met to take a photograph, and that these medical images are stored correctly. This study aimed to determine if medical professionals of an academic hospital make use of medical photography, and how the content is obtained, stored, transferred, and used. Methods: A 30-question questionnaire was distributed across 29 medical departments at Centro Hospitalar Universitário de São João (CHUSJ), a tertiary referral and teaching hospital in Porto, Portugal, with approximately 900 medical professionals. Quantitative statistical methods were used to analyse questionnaire responses. Results: There were a total of 257 respondents. Of these, 93% used medical photography, 70% used it to document a patient's clinical progress, 70% to ask for a second opinion, 56% for education, 65% for research and publication, and 68% to present at medical conferences. Medical photography was used by 33% weekly and 36% monthly, with 71% of respondents always asking for the patients' consent before taking a photograph. Doctors aged 20−40 years used photography more often than doctors over 40 years of age to document the clinical progress of the patients (77% and 52%, respectively, p = 0.01) and to ask for a second opinion (78% and 52%, respectively, p < 0.001). Conclusions: Our study shows that medical photography is a common practice amongst medical doctors. However, appropriate measures need to be created to obtain patients' consent, store images, and sure the security of patients' information.

Pre-clinical evaluation of LASSBio-1491: From in vitro pharmacokinetic study to in vivo leishmanicidal activity.

Leishmaniasis is a public health issue. It is among the top five parasitic illnesses worldwide and is one of the most neglected diseases. The current treatment disease includes limitations of toxicity, variable efficacy, high costs and inconvenient doses and treatment schedules. LASSBio-1736 was described as antileishmanial drug-candidate to cutaneous leishmaniasis, displaying plasma stability and with no preliminary signals of hepatic or renal toxicity. In this paper, we described the in vitro pharmacokinetic study of LASSBio-1491 (a less lipophilic isostere of LASSBio-1736) and it is in vitro and in vivo leishmanicidal activities. Our results demonstrated that LASSBio-1491 has high permeability, satisfactory aqueous solubility, long plasma and microsomal half-lives and low in vitro systemic clearance, suggesting a pharmacokinetic profile suitable for its use in a single daily dose. The antileishmanial effect of LASSBio-1491 was confirmed in vitro and in vivo. It exhibited no cytotoxic effect to mammalian cells and displayed good in -vivo effect against BALB/c mice infected with Leishmania major LV39 substrain, being 3 times more efficient than glucantime.

Keratoconus enlargement as a predictor of keratoconus progression.

Numerous approaches have been designated to document progression in keratoconus, nevertheless there is no consistent or clear definition of ectasia progression. In this present study, we aim to evaluate Keratoconus Enlargement (KCE) as a parameter to document ectasia progression. We define KCE as an increase of more than 1D in the anterior curvature of non-apical corneal areas. We have designed a longitudinal study in 113 keratoconic eyes to assess keratoconus progression. KCE was compared with variables commonly used for detection of keratoconus progression like Kmax, Km, K2, PachyMin, D-Index, Corneal Astigmatism and PRC of 3.0 mm centered on the thinnest point. The variations of keratometric readings, D-index and ELEBmax showed positive associations with KCE. Evaluating the performance of Kmax, D-index and KCE as isolated parameters to document keratoconus progression we found a sensitivity of 49%, 82% and 77% and a specificity of 100%, 95% and 66% to detect keratoconus progression (p < 0.001 for all). This difference in sensitivity can be explained by the changes in keratoconus outside the small area represented by Kmax. The inclusion of KCE should be considered in the evaluation of keratoconus progression in conjunction with other variables to increase the reliability of our clinical evaluation.

Neurosurgical anatomy of the floor of the third ventricle and related vascular structures.

PURPOSE: Anatomical knowledge of the floor of the third ventricle (FTV) is essential in avoiding surgical complications during endoscopic third ventriculostomy. The purpose of this study was to characterize the morphometry of FTV and related arteries, particularly the basilar artery (BA), as well as the factors that influence it. METHODS: Twenty-six formalin-fixed adult brains and two hundred adult brain MRIs were studied focusing on FTV and related arteries. Dimensions of interest were measured using image analysis software. Morphometric data obtained were statistically analysed. RESULTS: Distances between FTV, intermammillary sulcus (IMS), infundibulum, BA bifurcation, and posterior communicating arteries (PCoAs) were described on the cadavers and the MRIs. Distance between right and left PCoAs was greater at their anterior extremity (p < 0.001). Right PCoA was longer (p = 0.016). BA was lateralized in 58.4% of cases and its calibre was larger in males (p < 0.001). The distance from BA apex to FTV was inversely correlated with BA diameter (p < 0.001) and age (p = 0.004). Distance from IMS to infundibulum and the distance between both PCoAs were greater in MRI series when compared to cadaver series (p < 0.001). CONCLUSIONS: A quantitative description of the morphometry of the region of the FTV and related vessels was obtained, helping neurosurgeons in planning their surgical approach. The distance from BA apex to FTV was shorter in individuals with larger BA calibre and in older subjects. MRI studies were qualitatively superior to cadaveric studies in evaluating the anatomy of this region.

The Role of Atopy in the Choroidal Profile of Keratoconus Patients.

PURPOSE: Although classically classified as a non-inflammatory condition, an inflammatory basis for keratoconus (KC) appears to be a growing evidence. Recently, it has been shown that KC patients have an increased choroidal thickness (CT). Among inflammatory disorders, atopy has been associated with KC development; therefore, the aim of this study was to evaluate if the increased CT in patients with KC is related to atopy. METHODS: This is an analytical cross-sectional study of patients with KC. Patients were classified as atopic and non-atopic according to their atopy history (allergic rhinoconjunctivitis (AR), asthma (AA) and/or atopic dermatitis (AD)) and were also classified based on their eye rubbing habits. Choroidal profile of all subjects was evaluated using a Spectralis optical coherence tomography (OCT) device with enhanced depth imaging (EDI) mode. CT was measured and compared between groups at the center of the fovea and at 500 µm intervals along a horizontal section. A multivariable analysis, adjusted for sex, age, spherical equivalent, history of medication and atopy, was performed to assess the influence of atopy in CT. RESULTS: Of the 80 patients included, 51 were atopic and 29 non-atopic. Atopic patients showed a thicker choroid in every measured location than the non-atopic patients (mean subfoveal CT 391.53 µm vs 351.17 µm, respectively), although the differences were not statistically different. The multivariable analysis revealed that being atopic makes the choroid statistically thicker, on average, 55.14 µm, when compared to non-atopic patients (p=0.043). Furthermore, patients who are frequent eye rubbers have significantly thicker choroids than non-rubbers (p=0.004). CONCLUSION: Although some results do not reach statistical significance, atopic KC patients seem to have thicker choroids compared with non-atopic KC patients, suggesting a possible role for atopy in the choroidal profile of KC. This constitutes a completely new sight in this field of research that needs further investigation.

Increased choroidal thickness is not a disease progression marker in keratoconus.

The recent findings of increased Choroidal Thickness (CT) in Keratoconus (KC) patients raised the question of whether CT could be an indicator of progressive KC. To test this hypothesis, we evaluated and compared the choroidal profile in progressive and non-progressive KC. We ran a cross-sectional observational study in 76 patients diagnosed with KC, age 14-30, to assess KC progression. Progression was defined as when at least two of the studied variables confirmed progression (Kmax, Km, PachyMin, D-Index, Astig, K2, 3 mm PCR). Included patients performed a Spectralis Optical Coherence Tomography (OCT) with enhanced depth image (EDI) technology to evaluate choroidal profile. Choroidal measurements were taken subfoveally and at 500 µm intervals from the fovea, in 7 different locations, and compared between groups. Multivariate linear regression analyses were also performed to assess the influence of CT in KC progression. Thirty-six eyes (47.4%) were classified as KC progressors. The mean subfoveal CT observed in the total sample was 382.0 (± 97.0) µm. The comparison between groups (progressive and non-progressive KC) showed no differences in the locations evaluated (mean subfoveal CT difference between groups was 2.4 µm, p = 0.915). In the multivariate analysis CT seems not be influenced by KC progression (B = 6.72 µm, 95% CI - 40.09 to 53.53, p = 0.775). Assessment of choroidal profile does not appear to be a useful tool to differentiate progressive and non-progressive KC. Further research is needed in order to better understand the role of choroid in KC.

Prelaminated Supraclavicular Island Flap for Total Ear Reconstruction: A New Technique.

Major ear reconstruction has progressed over the past years with the emergence of new techniques directed mainly to patients without available or usable local skin. However, microsurgical transfer requires specific training and eligible patients. The authors report a successful ear reconstruction with a prelaminated supraclavicular island flap in 3 stages, which may be a valuable resource for selected patients or when microsurgery is not available. Advantages and disadvantages of this new technique are discussed, and a possible solution to achieve a more satisfactory result is suggested.

Sentindo-se diferente: uma revisão bibliográfica sobre a autoestima da pessoa com fissura labial e/ou palatina / Feeling different: a bibliographic review on the self-esteem of the person with cleft lip and / or palate

As fissuras de lábio e/ou palato (FL/P) são falhas congênitas que ocorrem durante o desenvolvimento do feto, na fase embrionária e podem comprometer a autoestima desses indivíduos em diversas etapas de seu desenvolvimento, alterando a avaliação que o indivíduo faz e o valor que atribui a si mesmo. Trata-se de um tema relevante, uma vez que, no Brasil, a incidência é de um a cada 650 nascimentos. Assim, o presente estudo teve como objetivo verificar e analisar pesquisas na literatura da área da Psicologia acerca da autoestima em indivíduos com FL/P e relacionar com fatores sociais implicados no desenvolvimento. Utilizou-se o como método a revisão bibliográfica sistemática. A BIREME foi utilizada como base de dados científicos a partir dos seguintes descritores: fissura labial; fissura palatina; lábio leporino; autoestima e Psicologia. Os resultados obtidos, após a aplicação dos critérios de exclusão, indicaram 10 que foram incluídos na amostra para análise e compilação final. As publicações foram agrupadas por afinidade temática, tendo como critérios a proximidade ao objetivo da pesquisa e a Psicologia como área de estudo. Os resultados encontrados discorrem principalmente sobre a ocorrência de bullying na infância e consequentemente sobre o impacto na autoimagem, assim como o fortalecimento da autoestima após a realização de cirurgias estéticas reparadoras. O estudo concluiu que a ocorrência de fissuras de lábio e palato são consideradas um fator de risco para o surgimento de dificuldades sociais e psicológicas advindas de uma autoestima negativa.(AU)

Cleft lip and / or palate (FL / P) are congenital flaws that occur during the development of the fetus, in the embryonic phase and can compromise the self-esteem of these individuals at various stages of their development, changing the assessment that the individual makes and the value you place on yourself. This is a relevant topic, since, in Brazil, the incidence is one in every 650 births. Thus, this study aimed to verify and analyze research in the literature in the field of Psychology about self-esteem in individuals with CL / P and to relate to social factors involved in development. The systematic bibliographic review was used as the method. BIREME was used as a scientific database based on the following descriptors: cleft lip; cleft palate; cleft lip; self-esteem and Psychology. The results obtained, after applying the exclusion criteria, indicated 10 that were included in the sample for analysis and final compilation. The publications were grouped by thematic affinity, having as criteria the proximity to the research objective and Psychology as a study area. The results found are mainly about the occurrence of bullying in childhood and, consequently, about the impact on self-image, as well as the strengthening of self-esteem after performing aesthetic repair surgeries. The study concluded that the occurrence of cleft lip and palate are considered a risk factor for the emergence of social and psychological difficulties arising from a negative self-esteem.(AU)

Endovascular Approach Versus Aortobifemoral Bypass Grafting: Outcomes in Extensive Aortoiliac Occlusive Disease.

OBJECTIVE: Compare technical, clinical, and economic outcomes between endovascular and open approaches in patients with type D aortoiliac occlusive disease according to the TransAtlantic Inter-Society Consensus. METHODS: Patients undergoing revascularization for type D aortoiliac lesions, either endovascular or open surgery approach, from 2 Portuguese institutions between January 2011 and October 2017 were included. The surgical technique was left to the surgeon discretion. Patients with common femoral artery affection, both obstructive and aneurysmatic, were excluded. RESULTS: Twenty-seven patients underwent aortobifemoral bypass and 32 patients were submitted to endovascular repair. The patients undergoing endovascular procedure were more likely to present with chronic heart failure (P = .001) and chronic kidney disease (P = .022) and less likely to have a history of smoking (P = .05). The mean follow-up period was 67.84 (95% confidence interval = 61.85-73.83) months. The open surgery approach resulted in a higher technical success (P = .001); however, limb salvage and patency rates were not different between groups. Endovascular approach was associated with a shorter length-of-stay, both inpatient (6 vs 9 days; P = .041) and patients admitted in the intensive care unit (0 vs 3.81 days; P = .001) as well as lower hospital expenses (US$9281 vs US$23 038; P = .001) with a similar procedure cost (US$2316 vs US$1173; P = .6). No differences were found in the postsurgical quality of life. CONCLUSION: Endovascular approach is, at least, clinically equivalent to open surgery approach and is more cost-efficient. The "endovascular-first" approach should be considered for type D occlusive aortoiliac lesions.

Neurosurgical anatomy of the insular cortex.

OBJECTIVE: The purpose of this study was to clarify the morphology of the insular cortex focusing not only on the shape of the insula, but also on sulcal and gyral organization. PATIENTS AND METHODS: Sixty formalin-fixed adult brain hemispheres had their insula exposed and photographed. The dimensions of each gyrus and sulcus were measured using an image analysis software. The morphometric data obtained was statistically analysed. RESULTS: The insular cortex shape alternates between triangular and trapezoid, being the triangular shape the most common (75%). The angle between the posterior and inferior peri-insular sulcus in the trapezoid insulae had a mean range of 131.17° (SD = 12.277). A minimum of 3 and a maximum of 6 insular gyri were observed, being 5 the most common total number of gyri observed. The accessory gyrus was present in 66% of the insulae and well-developed in 38% of the cases. A statistical association between the number of gyri in the posterior lobe and the presence of a novel gyrus or a more developed accessory gyrus in the anterior lobe was found (P = 0.006). The posterior short gyrus was the longest of the short gyri (P <  0.001), followed by the anterior short gyrus (P < 0.001). The anterior long gyrus was the largest of the long gyri (P = 0.003). The contribution of each of the short gyri to the formation of the insular apex was inconstant. The most common observed apex arrangement was the combination of the anterior and of the middle short gyri. CONCLUSIONS: This study makes a strong contribution to the understanding of the insular cortex anatomy, allowing neurosurgeons to be more capable to decide the best approach to this cortical area.

Regulation of murine arthritis by systemic, spinal, and intra-articular adrenoceptors.

BACKGROUND: The regulation of the immune system by the sympathetic nervous system is allowing the design of novel treatments for inflammatory disorders such as arthritis. In this study, we have analyzed the effects of α- and ß-adrenoceptor agonists injected subcutaneously, intrathecally, or intra-articularly in zymosan-induced arthritis. METHODS: Murine arthritis was induced by intra-articular (knee joint) injection of zymosan. α1 (phenylephrine), α2 (clonidine), ß1 (dobutamine), or ß2 (salbutamol)-adrenoceptor agonists were injected subcutaneously (sc), intrathecally (it), or intra-articularly (ia) to activate peripheral, spinal, or intra-articular adrenoceptors and to study their effects on articular edema formation and neutrophil migration into the synovial cavity. RESULTS: Treatments with phenylephrine did not affect the edema formation, but it increased neutrophil migration when injected subcutaneously (155.3%) or intra-articularly (187.7%). Treatments with clonidine inhibited neutrophil migration (59.9% sc, 68.7% it, 42.8% ia) regardless of the route of administration, but it inhibited edema formation only when injected intrathecally (66.7%) or intra-articularly (36%) but not subcutaneously. Treatments with dobutamine inhibited both edema (42.0% sc, 69.5% it, 61.6% ia) and neutrophil migration (28.4% sc, 70.3% it, 82.4% ia) in a concentration dependent manner. Likewise, all the treatments with salbutamol also inhibited edema formation (89.9% sc, 62.4% it, 69.8% ia) and neutrophil migration (76.6% sc, 39.1% it, 71.7% ia). CONCLUSION: Whereas the ß-adrenoceptor agonists induced anti-inflammatory effects regardless of their route of administration, α1- and α2-adrenoceptor agonists induced either pro- and anti-inflammatory effects, respectively.
