Effectiveness of diagnosis and early treatment of ocular motility alterations in premature infants
Objective: Prematurity often results in important developmental sequelae of brain structures, particularly those involved in processing visual information, such as the optic nerve, primary visual cortex and visuomotor integration areas. The aim of this study is to analyse the functionality of the sensory and motor pathways of the visual system by means of an orthoptic-ophthalmological assessment. Materials and methods: In this retrospective study, 151 records were examined, covering a period from 2000 to 2020, of preterm patients with gestational age < 32 weeks and birth weight ≤ 1,500 g up to an average age of about 8 years, referred to the Centre for Paediatric Ophthalmology and Strabology of the Ophthalmology Clinic of the Policlinico Umberto I, La Sapienza University of Rome, who underwent a complete ophthalmological and orthoptic assessment including the following tests measurement of ocular deviations according to the Hirschberg method, Lang I-II test, Titmus Stereotest, objective convergence assessment and ocular motility examination. Results: From the charts reviewed, 24.5% (37/151) of patients had Retinopathy of the Premature (ROP); while 38% of the whole sample (57/151) had strabismic amblyopia, of the latter only 31.5% (18/57) had ROP. In 8% of patients (12/151) the stereoscopic sense was absent, in 45% (8/151) stereopsis was gross (> 60 seconds of arc). In addition, 20.52 % (31/151) had a manifest eye deviation. 7.28% (11/151) had hypermetropia in the right eye (RE); 7.95% (12/151) hypermetropia in the left eye (OS); 3.31% of the patients (5/151) had myopia in the RE; 2% (3/151), myopia in the left eye (LE). In addition, the study of ocular motility revealed varying degrees of alteration poorly correlated with prematurity status. Conclusion: It was found that amblyopia, stereopsis and objective convergence are more affected by ROP than strabismus, refractive defects and ocular motility, indicating that premature children are particularly susceptible to ophthalmological and orthoptical alterations
A vulnerabilidade e a mente : conflitos simbólicos entre o diagnóstico institucional e a perspectiva de jovens em cumprimento de medida socioeducativa
Nas últimas duas décadas a utilização do termo vulnerabilidade foi expandida para diferentes campos de conhecimento e de intervenção. Neste artigo analisamos o uso da noção de vulnerabilidade no âmbito do sistema socioeducativo como um componente das relações de poder entre instituições de execução de medidas socioeducativas e jovens atendidos. Baseado em pesquisa etnográfica realizada na Região Metropolitana de São Paulo em 2009, 2010 e 2011, com a participação de 14 adolescentes em cumprimento de medidas socioeducativas, o texto analisa o conflito entre o relatório psicológico de um jovem e sua própria interpretação ao falar sobre os mesmos aspectos de sua vida. Discute também como o jovem, intrincado diferentemente por códigos distintos, enseja em sua própria existência conflitos simbólicos que têm escapado às práticas do sistema socioeducativo. O encontro da ideia de vulnerabilidade no relatório psicológico com a perspectiva da mente como atributo de um jovem configura-se um campo de disputas simbólicas entre visões da capacidade de autorregulação do indivíduo
Intravitreal injections primary prevention: a case-control study
OBJECTIVE: Intravitreal injec tions (IVI) of therapeutic substances are one of
the most common procedures in ophthalmol ogy and, for sure, the most feared complica tion of them is endophthalmitis. Nowadays, a
precise prophylactic protocol does not exist to
avoid these infections, and the role of new anti septic drops is an interesting field of research
in this regard. In this article we are going to dis cuss the tolerability and the efficacy of a new
antiseptic drop based on a solution of hexam idine diisethionate 0.05% (Keratosept®; Brus chettini Srl, Genoa, Italy).
PATIENTS AND METHODS: This was a sin gle-center, case-control study, comparing the
in vivo effect of hexamidine diisethionate 0.05%
with povidone iodine 0.6% solution during IVI
program. Ocular bacterial flora composition
was analyzed with a conjunctival swab on day
0. After injection patients underwent antibac terial prophylaxis with Keratosept for 3 days or
povidone iodine 0.6%. A second conjunctival
swab was collected on day 4 and patients were
asked to fulfill a questionnaire based on the OS Di model, to investigate the ocular tolerability of
the drug administered.
RESULTS: Efficacy was tested on 50 patients,
25 of whom received hexamidine diisethionate
0.05% drops and the other 25 received povidone
iodine 0.6% solution drops, 100 total conjuncti val swabs, 18 positive swabs before and 9 after
treatment for the first group and 13 before and 5
after for the second one. Tolerability was tested
on 104 patients, 55 underwent Keratosept thera py and 49 povidone iodine one.
CONCLUSIONS: Keratosept demonstrated
a good efficacy profile with better tolerability
against povidone iodine in the analyzed sample
Does episiotomy always equate violence in obstetrics? Routine and selective episiotomy in obstetric practice and legal questions
OBJECTIVE: The study’s main goal is to figure out whether episiotomy, a widely applied invasive procedure, may constitute a determining factor of liability for practitioners according to the standards of obstetric violence. MATERIALS AND METHODS: The authors have aimed to analyze laws and documentation issued on the matter by sovereign states, statements and remarks from International health organizations, in addition to scientific article available on the main search engines (PubMed, Scopus, Google Scholar) and legal databases (Lexis, Justia). RESULTS: The body of research has highlighted the existence of a wide-ranging agreement as to routine episiotomy, deemed to be a scientifically unfounded procedure, and which should, therefore, be avoided. By virtue of that, routine episiotomy might easily give rise to charges and liability for doctors and midwives alike; likewise to claims may stem from a failure to perform an episiotomy when it was actually needed. CONCLUSIONS: Unlike routine episiotomy, selective episiotomy is far more unlikely to cause charges of obstetric violence against operators. Unfortunately, the criteria in order to establish when a selective episiotomy is indicated are far from consistent and would require an additional effort on the part of scientific societies towards a more clearly defined and shared description
Should the visceral peritoneum at the bladder flap closed at caesarean sections a post partum sonographic and clinical assessment?
Objective. To compare cesarean section (CS) using open or closed visceral peritoneum of the bladder flap (BF) in relation to fluid collection in vesico-uterine space (VUS) by ultrasound (US) and clinical outcome. Material and methods. A prospective cohort of repeat CS in 474 in advanced first and second stage of labor was studied. All women underwent a Misgav Ladach CS, in local combined anesthesia. These were divided into two groups by surgical management of the BF at the time of CS: Group I (n?262), with visceral peritoneum left open and Group II (n?212), with visceral peritoneum closed. An US check for the fluid collections in the VUS was done in the third post-operative day. The two groups were also clinically compared for: intra-operative estimated blood loss, the need for post-CS pain killers, febrile morbidity and duration of hospital stay. Results. Visceral peritoneum (VP) closure resulted in a significant increase blood collections in the VUS (p50.05). VP closure resulted in a significantly higher morbidity in all the following parameters. Rate of BFHs, post-operative fever, need for post-operative analgesia, require antibiotic administration and prolonged hospitalisation (p50.05). Conclusions. VP suturing of women requiring CS for dystocia is associated to increased rate of blood collection in the VUS, which could possibly explain the higher rate of puerperal complications in these patients. These data clearly indicate that suturing the VP of the BF in women undergoing CS for dystocia is contraindicated. This data could be probably extrapolated to all cesarean deliveries
Double hit: mantle cell lymphoma associated with squamous cell carcinoma or chalazion? A case report
A few cases of ocular adnexal neoformations related with MCL have been reported in the literature. We present a rare case of tumour duplicity: mantle cell lymphomas (MCL) associated with squamous cell carcinoma (SCC) localised at the level of the ocular adnexa, on left upper eye lid mass since two years of 18 mounth duration in a 57-year-old man who had previously been diagnosed with stage IV MCL for 14 months. The patient had been treated according to the R-DHAP scheme for 4 cycles, in anticipation of a possible autologous HSC transplant, which was not carried out due to a positive diagnosis at the end-of-cycle osteomedullary biopsy (BOM) check. Ophthalmological examination was performed, and afther surgical removal histological examination proved to be squamous cell carcinoma (SCC). The aim of this case report is to decode the signs, symptoms and factors associated with the formation, that appear to be a chalazion, at an early stage in order to prevent the overgrowth of the mass that could invade the surrounding tissues by infiltrating them, as well as negative aesthetic outcomes of the surgery due to the excessive size of the mass, which could compromise the patient's quality of life
Intrapartum sonography of fetal head in second stage of labor with neuraxial analgesia: a literature review and possible medicolegal aftermath
Intrapartum ultrasound (IU) is a valid support to obstetric management of fetal head progression in the second stage of labor in nulliparous with neuraxial labor analgesia (NLA). Nulliparous with NLA may have a prolonged the second stage of labor. The aim of this literature review was to evaluate the mode of delivery, as well as maternal and fetal morbidities associated with missed progression of fetal head detected with IU in the second stage of labor in nulliparous women with NLA.MATERIALS AND METHODS: The literature review was performed using PubMed, Cochrane, Medline, EMBASE, Scopus, Google Scholar and book chapters searches to identify relevant articles from 2001 to 2019, evaluating the mode of delivery and morbidities of the second stage of labor. Search terms used were “Intrapartum ultrasound”, “dystocia”, “prolonged labor”, “neuraxial analgesia”, “persistent occiput posterior position”, “asynclitism”, “second stage of labor”, “medico-legal aftermath”. Prolonged second stage was defined as three hours and more. Retrospective case series of women with prolonged second stage of labor with NLA were identified. The primary outcome was the incidence of operative vaginal delivery (OVD) and cesarean delivery (CS).
RESULTS: The use of NLA may determine a prolonged second stage of labor (PSSL). IU when compared to the traditional vaginal digital examination (VDE) demonstrated the highest degree of diagnostic accuracy.
CONCLUSIONS: The use of IU during NLA can aid in the diagnosis of fetal head progression, station or malposition and malrotation, alerts obstetrician on the possibility of dystocic labor, indicating to stop the drug administration in NLA and shift to OVD or CS. Extending the second stage of labor beyond current American College of Obstetricians and Gynecologists (ACOG) recommendations is beneficial. The ISUOG guidelines recommended the clinical application of IU to diagnose the persistent occiput posterior position (POPP) and asynclitism (A) in dystocic labor and produce photographic evidence of the case. Maternal and neonatal complications, medicolegal consequences and litigation can decrease if the IU device is used as good practice
Uterine fibroid pseudocapsule studied by transmission electronmicroscopy.
OBJECTIVE: The fibroid pseudocapsule is a structure which surrounds the uterine fibroid, separates it from the uterine tissue and contains a vascular network rich in neurotransmitters like a neurovascular bundle. The authors examined the composition of the fibroid pseudocapsule using electron microscopy.
STUDY DESIGN: Twenty non-pregnant patients were submitted to laparoscopic myomectomy by the intracapsular method and samples of the removed pseudocapsules were analyzed using transmission electron microscopy.
RESULTS: At the ultrastructural level the pseudocapsule cells have the features of smooth muscle cells similar to the myometrium. So, the pseudocapsules are part of the myometrium which compresses the leiomyoma.
CONCLUSION: This ultrastructural feature suggests that when removing fibroids their pseudocapsules should be preserved. This study confirms preliminary evidence that pseudocapsules contain neuropeptides together with their related fibers, as a neurovascular bundle. The surgeon's behavior should be directed to carefully control and spare this muscular surrounding tissue during fibroid excision, in order to preserve the myometrium as much as possible
Effectiveness of Mp-3 Microperimetric Biofeedback Fixation Training For Low Vision Rehabilitation in Patients Treated With Corticosteroid Ivt in Retinal Vein Occlusions
Mariaelena Malvasi,1 Sabrina Compagno,1 Alessandro Segnalini,1 Vito Maurizio Malvasi,2 Fernanda Pacella,3 Paolo Turchetti,4 Elena Pacella1 1Department of Sense Organs, Faculty of Medicine and Dentistry, Sapienza University of Rome, Rome, Italy; 2Department of Odontostomatological and Maxillo-Facial Sciences, Sapienza University of Rome, Rome, Italy; 3Department of Ophthalmology, Carlo Poma Hospital, Mantua, Italy; 4National Institute for Health, Migration and Poverty (INMP/NIHMP), Rome, ItalyCorrespondence: Elena Pacella, Department of Sense Organs, University Sapienza, Rome, Policlinico Umberto I, Viale, del Policlinico 155, Rome, 00161, Italy, Email [email protected]: The success of fixation training using microperimetric biofeedback (MP-3 MBFT) in the realm of visual rehabilitation for patients with central vision loss caused by macular pathologies is well established. This study aimed to assess the effectiveness and safety of visual rehabilitation with microperimetric biofeedback in consolidating the benefits obtained, with the goal of reducing the need for repeated intravitreal injections (IVT). Specifically, the focus is on the eyes of patients with central vision loss treated with slow-release corticosteroid IVT following retinal venous thrombosis (RVO), aiming to enhance and maintain postoperative efficacy.Methods: This retrospective review involved the examination of 44 eyes affected by macular edema due to RVO associated with central vision loss. Patients were divided into two groups, with only one undergoing ten sessions of 10-minute visual rehabilitation with a microperimeter (MP-3 MBFT) after IVT over a period of 20 weeks.Results: All the treated patients demonstrated good tolerance to the procedure, with no reported complications. A comparison of best-corrected visual acuity (BCVA), retinal sensitivity recorded with a microperimeter, and pre-IVT fixation stability revealed statistically significant improvements at the end of the first month after IVT. However, the treatment group continued to exhibit superior and more enduring results at four months post-IV.Conclusion: The synergistic use of MP-3 MBFT rehabilitation after IVT with slow-release corticosteroids has proven particularly effective in improving BCVA and long-term fixation stability. This led to a significant reduction in the number of required IVTs, with no related adverse events. The authors argue that biofeedback utilization represents a noninvasive therapeutic option devoid of contraindications and easy to implement and that it positively contributes to the overall patient experience regarding quality of life in advanced stages of macular diseases.Keywords: microperimetric biofeedback, visual rehabilitation, macular edema, intravitreal corticosteroid, retinal vein occlusio
