RESUMO

BACKGROUND: Incontinentia pigmenti (IP) is a rare multisystemic X-linked dominant genetic disorder characterized by highly diagnostic skin lesions. The disease can be misdiagnosed in infants, and complications affecting the eyes and/or the brain can be severe. Our objective was to highlight the urgency of an appropriate diagnosis and management strategy, as soon as the first symptoms appear, and the need for a well-codified monitoring strategy for each child. METHODS: An in-depth literature review using a large number of databases was conducted. The selection criteria for articles were literature review articles on the disease, case series and retrospective studies based on the disease, clinical studies (randomized or not) on treatment, articles discussing patient care and management (treatment, diagnosis, care pathways), and recommendations. The research period was from 2000 until 2018. A group of multidisciplinary experts in IP management was involved, issued from different healthcare providers of the European Network for Rare Skin Diseases (ERN-Skin). The final recommendations have been submitted to two patient representative associations and to a general practitioner and a neonatal specialist prior to their finalization. RESULTS AND CONCLUSION: The diagnosis of IP must be promptly performed to detect potential extracutaneous manifestations, thus allowing the timely implementation of specific therapeutic and monitoring strategies. Eye involvement can be a therapeutic urgency, and central nervous system (CNS) involvement requires a very rigorous long-term follow-up. Assessments and patient support should take into account the possible co-occurrence of various symptoms (including motor, visual and cognitive symptoms).

RESUMO

Neuroglobin (Ngb) is expressed in the central and peripheral nervous system, cerebrospinal fluid, retina, and endocrine tissues where it is involved in binding O2 and other gasotransmitters. Several studies have highlighted its endogenous neuroprotective function. Huntington's disease (HD), a dominant hereditary disease, is characterized by the gradual loss of neurons in discrete areas of the central nervous system. We analyzed the expression of Ngb in the brain tissue of a mouse model of HD, in order to define the role of Ngb with respect to individual cell type vulnerability in HD and to gender and age of mice. Our results showed different expressions of Ngb among neurons of a specific region and between different brain regions. We evidenced a decreased intensity of Ngb at 13 weeks of age, compared to 7 weeks of age. The double immunofluorescence and fluorescence resonance energy transfer (FRET) experiments showed that the co-localization between Ngb and huntingtin at the subcellular level was not close enough to account for a direct interaction. We also observed a different expression of Ngb in the striatum, depending on the sex and age of animals. These findings provide the first experimental evidence for an adaptive response of Ngb in HD, suggesting that Ngb may exert neuroprotective effects in HD beyond its role in reducing sensitivity to oxidative stress.

RESUMO

BACKGROUND: Hemorrhoidal prolapse is a common benign disease. The introduction of circular-stapled hemorrhoidopexy as an alternative to the conventional hemorrhoidectomy led to a new spectrum of postoperative outcomes and complications. The aim of the present study was to evaluate long-term results after stapled hemorrhoidopexy. METHODS: All the patients who had stapled hemorrhoidopexy using a PPH03 stapler, from January 2003 to December 2005, were retrospectively collected in a dedicated database. Between March and May 2016, all the patients were asked by phone to complete a questionnaire. The study evaluated anatomical recurrence, symptom recurrence and frequency, and satisfaction after surgery. The postoperative complications recorded were hemorrhage, hematoma, urinary retention, anastomotic stenosis, persistent anal pain, tenesmus, and impaired anal continence evaluated also with the Faecal Incontinence Severity Index score. RESULTS: One hundred and ninety four patients were identified and 171 completed the questionnaire. The mean follow-up was 12 ± 0.8 years (range 11-13 years). Anatomical self-reported prolapse recurrence was 40.9% (n = 70). In 75.6% (n = 129) of patients, the severity and frequency of symptoms improved. The overall complication rate was 56.7% (n = 40) with a serious adverse event rate of 8.7% (n = 15). The overall tenesmus rate was 38.2% (n = 65) and the overall impaired continence rate was 39.1% (n = 67). Medical therapy was still required occasionally by 40.3% (n = 69) of the patients and 9.3% (n = 16) of the patients underwent surgery for recurrence. Patient satisfaction rate was good (≥ 3 on a scale of 1 to 5) in 81.2% (n = 139) of cases. CONCLUSIONS: The study showed that stapled hemorrhoidopexy using the first-generation devices is safe and feasible but associated with a high recurrence and incontinence rate. More stringent selection criteria in association with the use of large volume devices can lead to better results in the future.

RESUMO

Endometriosis is a benign condition described as the presence of endometrial- like tissue found outside the uterine cavity. Hepatic endometriosis is one of the rarest localization of extrapelvic endometriosis, only 22 cases have been reported in the literature. The preoperative diagnosis of hepatic endometriosis is rather difficult because in about the half of the patient affected they had no history of endometriosis. Moreover radiological images reveal no characteristic findings for hepatic endometriosis. It is often described as cystic mass with or without solid component, difficult to distinguish from hepatic abscess, hematoma, cystoadenoma or malignant neoplasia. We report a case of a 27-year-old female with a large cystic mass involving the left lobe of the liver. The patient underwent laparoscopic exploration and converted to laparotomy for resection of giant hepatic endometriosis.

RESUMO

Mendelian primary immunodeficiency diseases (MPIDs) are rare disorders affecting distinct constituents of the innate and adaptive immune system. Although they are genetically heterogeneous, a substantial group of MPIDs is due to mutations in genes affecting the nuclear factor-κB (NF-κB) transcription pathway, essential for cell proliferation and cell survival and involved in innate immunity and inflammation. Many of these genes encode for crucial regulatory components of the NF-κB pathway and their mutations are associated with immunological and developmental signs somehow overlapping in patients with MPIDs. At present, nine different MPIDs listed in the online mendelian inheritance in man (OMIM) are caused by mutations in at least nine different genes strictly involved in the NF-κB pathway that result in defects in immune responses. Here we report on the distinct function of each causative gene, on the impaired NF-κB step and more in general on the molecular mechanisms underlining the pathogenesis of the disease. Overall, the MPIDs affecting the NF-κB signalosome require a careful integrated diagnosis and appropriate genetic tests to be molecularly identified. Their discovery at an ever-increasing rate will help establish a common therapeutic strategy for a subclass of immunodeficient patients.

RESUMO

BACKGROUND: Surfactant is a well-established therapy for preterm neonates affected by respiratory distress syndrome (RDS). The goals of different methods of surfactant administration are to reduce the duration of mechanical ventilation and the severity of bronchopulmonary dysplasia (BPD); however, the optimal administration method remains unknown. This study compares the effectiveness of the INtubate-RECruit-SURfactant-Extubate (IN-REC-SUR-E) technique with the less-invasive surfactant administration (LISA) technique, in increasing BPD-free survival of preterm infants. This is an international unblinded multicenter randomized controlled study in which preterm infants will be randomized into two groups to receive IN-REC-SUR-E or LISA surfactant administration. METHODS: In this study, 382 infants born at 24+0-27+6 weeks' gestation, not intubated in the delivery room and failing nasal continuous positive airway pressure (nCPAP) or nasal intermittent positive pressure ventilation (NIPPV) during the first 24 h of life, will be randomized 1:1 to receive IN-REC-SUR-E or LISA surfactant administration. The primary outcome is a composite outcome of death or BPD at 36 weeks' postmenstrual age. The secondary outcomes are BPD at 36 weeks' postmenstrual age; death; pulse oximetry/fraction of inspired oxygen; severe intraventricular hemorrhage; pneumothorax; duration of respiratory support and oxygen therapy; pulmonary hemorrhage; patent ductus arteriosus undergoing treatment; percentage of infants receiving more doses of surfactant; periventricular leukomalacia, severe retinopathy of prematurity, necrotizing enterocolitis, sepsis; total in-hospital stay; systemic postnatal steroids; neurodevelopmental outcomes; and respiratory function testing at 24 months of age. Randomization will be centrally provided using both stratification and permuted blocks with random block sizes and block order. Stratification factors will include center and gestational age (24+0 to 25+6 weeks or 26+0 to 27+6 weeks). Analyses will be conducted in both intention-to-treat and per-protocol populations, utilizing a log-binomial regression model that corrects for stratification factors to estimate the adjusted relative risk (RR). DISCUSSION: This trial is designed to provide robust data on the best method of surfactant administration in spontaneously breathing preterm infants born at 24+0-27+6 weeks' gestation affected by RDS and failing nCPAP or NIPPV during the first 24 h of life, comparing IN-REC-SUR-E to LISA technique, in increasing BPD-free survival at 36 weeks' postmenstrual age of life. TRIAL REGISTRATION: ClinicalTrials.gov NCT05711966. Registered on February 3, 2023.

RESUMO

Patients with haemophilia A and inhibitors are at high risk for severe bleeding, progression of joint disease and deterioration of health-related quality of life (HRQoL). To determine the impact of prophylaxis with an activated prothrombin complex concentrate (aPCC) on HRQoL, HRQoL was assessed using the Short-Form (SF)-36 Health Survey and the EQ-5D questionnaire in subjects ≥ 14 years participating in a prospective, randomized, crossover study comparing 6 months of aPCC prophylaxis with 6 months of on-demand therapy. Eighteen of 19 patients completed the survey or questionnaire before and after the on-demand therapy and prophylaxis periods. A general trend towards improved HRQoL after prophylaxis was observed for the 18 evaluable patients in all SF-36 dimensions except for vitality/energy and physical functioning. After prophylaxis, 'good responders,' defined as patients experiencing ≥ 50% reduction in bleeding, exhibited statistically and clinically significant differences in the physical component score (P = 0.021), role - physical (P = 0.042), bodily pain (P = 0.015), and social functioning (P = 0.036). Similarly, the EQ-5D health profile showed a trend towards improvement after prophylaxis in all evaluable patients. Among the good responders, improvements did not differ from those observed after on-demand treatment. EQ visual analogue scale values were slightly improved following prophylaxis for all evaluable patients and the EQ-5D utility index improved in the good responders only. During prophylaxis, patients missed significantly fewer days from school or work because of bleeding than during on-demand treatment (P = 0.01). In conclusion, by significantly reducing bleeding frequency in good responders, aPCC prophylaxis improved HRQoL compared with on-demand treatment.

RESUMO

BACKGROUND AND STUDY AIMS: Thermal injury of the colonic wall during polypectomy may induce complications such as bleeding and perforation. To date, the role of the snare material in these injuries has not been examined. The aim of this study was to evaluate the depth of colonic post-polypectomy thermal wall injury induced by tungsten and steel endoscopic snares, in an effort to reduce electrosurgery-related complications. MATERIALS AND METHODS: This was a single tertiary center experimental study in a porcine model. A total of 90 polypectomies where performed in three live pigs under general anesthesia, using both steel and tungsten snares by cut, coagulation, and blend current modes. The pigs were then euthanized and their colons examined histologically. RESULTS: Steel snares induced significantly deeper tissue injury than tungsten snares in the pure cut mode (Pearson χ2 = 6.136, P = 0.013). The ordinal logistic regression analysis showed that the current mode and snare material were significantly associated with the ordinal score for the depth of injury. Thus, cut mode was positively associated with a lower score and coagulation mode with a higher score. In addition, tungsten was significantly associated with a lower depth of tissue injury. CONCLUSIONS: Due to its inherent electrical properties, tungsten is very well suited for manufacture into electrosurgical endoscopic devices. Thus, tungsten snares may be advantageous for routine use in endoscopic polypectomy, although further studies are needed to confirm these promising findings in human patients.

RESUMO

Caused by Mycobacterium tuberculosis, TB is the leading cause of death from an infectious disease. HIV and diabetes are recognised risk factors for progression of TB disease and both have a strong impact on the diagnosis and management of TB, threatening efforts to end TB globally. Here we provide the latest data on the complex interplay between these conditions. TB patients with HIV present systemic immune activation, increased HIV viral load, more severe clinical presentations and reduced success of TB therapy. Similarly, TB patients with diabetes are characterised by an exaggerated adaptive immunity, worsening of the clinical presentations and a higher risk for multidrug resistance and treatment failure. It is important to strengthen resources to prevent these comorbidities from occurring and to implement screening, early diagnosis and appropriate management strategies.

RESUMO

Extracorporeal shock wave therapy improves erectile function in patients with Peyronie's disease. However, erectile dysfunction still persists in many cases. We aimed to investigate the effects of extracorporeal shock wave therapy plus tadalafil 5 mg once daily in the management of patients with Peyronie's disease and erectile dysfunction not previously treated. One hundred patients were enrolled in a prospective, randomized, controlled study. Patients were randomly allocated to receive either extracorporeal shock wave therapy alone for 4 weeks (n = 50) or extracorporeal shock wave therapy plus tadalafil 5 mg once daily for 4 weeks (n = 50). Main outcome measures were: erectile function (evaluated through the shortened version of the International Index of Erectile Function), pain during erection (evaluated through a Visual Analog Scale), plaque size, penile curvature and quality of life (evaluated through an internal questionnaire). Follow-up evaluations were performed after 12 and 24 weeks. In both groups, at 12 weeks follow-up, mean Visual Analog Scale score, mean International Index of Erectile Function score and mean quality of life score ameliorated significantly while mean plaque size and mean curvature degree were unchanged. Intergroup analysis revealed a significantly higher mean International Index of Erectile Function score and quality of life score in patients receiving the combination. After 24 weeks, intergroup analysis revealed a significantly higher mean International Index of Erectile Function score and mean quality of life score in patients that received extracorporeal shock wave therapy plus tadalafil. In conclusion extracorporeal shock wave therapy plus tadalafil 5 mg once daily may represent a valid conservative strategy for the management of patients with Peyronie's disease and erectile dysfunction.

RESUMO

Highly active antiretroviral therapy (HAART) of HIV+ patients with haemophilia poses specific questions on safety and effectiveness because of long-lasting HIV infection, multidrug resistance, concomitant chronic liver disease and bleeding risk. Raltegravir belongs to a new class of drugs that inhibits HIV integrase and is known to have a good effectiveness and safety profile. The aim of this study was to evaluate safety and effectiveness of HAART with raltegravir in patients with haemophilia. HIV+ patients with haemophilia treated with raltegravir for ≥ 6 months were included in this retrospective study. Safety criteria were: occurrence of any adverse event, unexpected blood test abnormalities and increased consumption of coagulation factors. Effectiveness criteria were: no disease progression, viral load <40 HIV-RNA copies mL(-1) and increased or stable CD3+ CD4+ cell count above 200 cells cmm(-1). Seven patients with HCV co-infection underwent treatment with raltegravir for a median of 20 months (min-max: 7-30). Before starting treatment with raltegravir, three patients had CD3+ CD4+ cell counts <200 cells cmm(-1). The median viral load was 7547 copies mL(-1) (min-max: <40-37,807). During treatment, no new sign of disease progression was observed. All patients showed suppression of viral replication (<40 HIV-RNA copies mL(-1)). CD3+ CD4+ cell counts showed a median increase of 152 cells cmm(-1) (min-max: 40-525). Two patients suffered from peripheral neuropathy, which was deemed as possibly associated with raltegravir. There was no evidence of increased bleeding frequency, modification of bleeding sites and lack of response to replacement therapy. Raltegravir-based HAART appeared to be effective and generally well-tolerated in patients with haemophilia, and it might represent a useful option in these patients.

RESUMO

BACKGROUND: The oocyte-to-embryo transition (OET) requires a co-ordinated transcriptional programme acting through evolutionarily conserved events, and transcription factors (TFs) are known to control these processes. Here, we focus on nuclear factor (NF)-κB, a TF involved in several cellular processes, studying NFκB-inhibitor (NFKBIA) mRNA and its protein product, IκBα, during OET. NFKBIA and IκBα are part of a regulatory loop, as IκBα is the major down-regulator of NF-κB activation while NFKBIA transcription is activated by NF-κB. METHODS AND RESULTS: We found a dynamic correlation between NFKBIA transcript, expression of IκBα-protein and activation of NF-κB/p65 in bovine oocyte and embryo. During the transition from immature to in vitro matured bovine oocyte, we observed a decrease in maternal NFKBIA mRNA and a parallel increase of the IκBα-protein (both P < 0.05). In the embryo, NFKBIA neo-synthesis is activated as a consequence of embryo genome activation (EGA), and IκBα decreases. NF-κB/p65-binding activity was detectable at low levels in immature oocyte, disappeared in dormant metaphase II oocyte and was strong in the embryo, during embryonic NFKBIA synthesis. The level of NF-κB/p65 DNA binding correlates with the timing of meiotic silencing during bovine oocyte maturation and embryonic transcription reprogramming. CONCLUSIONS: The IκBα/NF-κB circuit appears to be a tightly stage-controlled mechanism that could govern OET, being activated at EGA. Our findings represent the first characterization of NFKBIA and IκBα as maternal effectors in both the bovine oocyte and embryo. We suggest a role for NFKBIA as a marker of NF-κB/p65 activation in the human oocyte and early embryo.

RESUMO

AIMS: Myotonic dystrophy type 2 (DM2) is caused by a [CCTG]n intronic expansion in the zinc finger protein 9 (ZNF9) gene. As for DM1, sharing with DM2 a similar phenotype, the pathogenic mutation involves a transcribed but untranslated genomic region, suggesting that RNA toxicity may have a role in the pathogenesis of these multisystem disorders by interfering with common cellular mechanisms. However, haploinsufficiency has been described in DM1 and DM2 animal models, and might contribute to pathogenesis. The aim of the present work was therefore to assess ZNF9 protein expression in rat tissues and in human muscle, and ZNF9 subcellular distribution in normal and DM2 human muscles. METHODS: Polyclonal anti-ZNF9 antibodies were obtained in rabbit, high pressure liquid chromatography-purified, and used for Western blot, standard and confocal immunofluorescence and immunogold labelling electron microscopy on a panel of normal rat tissues and on normal and DM2 human muscles. RESULTS: Western blot analysis showed that ZNF9 is ubiquitously expressed in mammalian tissues, and that its signal is not substantially modified in DM2 muscles. Immunofluorescence studies showed a myofibrillar distribution of ZNF9, and double staining with two non-repetitive epitopes of titin located it in the I bands. This finding was confirmed by the visualization of ZNF9 in close relation with sarcomeric thin filaments by immunogold labelling electron microscopy. ZNF9 distribution was unaltered in DM2 muscle fibres. CONCLUSIONS: ZNF9 is abundantly expressed in human myofibres, where it is located in the sarcomeric I bands, and no modification of this pattern is observed in DM2 muscles.

RESUMO

Established beliefs concerning outcomes following anterior urethral reconstruction are changing, both with regards to the genital cosmetics and to the impact on sexual activity. Today, the aim of stricture repair is not only to reinstate urinary function but also to safeguard sexual activity and guarantee genital cosmesis. A thorough evaluation of anterior urethroplasty results should include the sexual viewpoint which appears to play an important role in overall post-operative patient satisfaction. The most commonly reported sexual problems following anterior urethroplasty include: erectile and ejaculatory dysfunction, penile curvature or shortening, dissatisfaction with genital cosmetic appearance, sensorial impairment of glans. The prevalence of specific post-operative sexual problems may be related to the site of reconstruction (penile or bulbar) and to the technique of urethroplasty employed. In penile urethral reconstruction, the wide use of buccal mucosa grafts seems to excel the use of skin flaps which easily distort the cosmesis and elasticity of the penis. In bulbar reconstructions, graft augmentation techniques seem to impact less on sexual outcome than excision anastomotic techniques. Therefore, the policy of primarily indicating an excision anastomotic procedure, whenever possible, should come under scrutiny. Eventual sexual outcomes should be incorporated in the choice of the optimal anterior urethral reconstruction and in pre-operative patient counselling.

RESUMO

A coronavirus disease 2019 (COVID-19) surveillance study was performed in March-April 2020 among asymptomatic healthcare workers (HCWs) at a specialist infectious diseases hospital in Naples, Italy. All HCWs underwent two rounds of molecular and serological testing for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). One hundred and fifteen HCWs were tested; of these, two cases of infection were identified by reverse transcriptase polymerase chain reaction and two HCWs were SARS-CoV-2 immunoglobulin G seropositive. The overall prevalence of current or probable previous infection was 3.4%. The infection rate among HCWs was reasonably low. Most of the infected HCWs had been asymptomatic for the preceding 30 days, which supports the need for periodic screening of HCWs for COVID-19.

RESUMO

PURPOSE: We prospectively compared gadoliniumenhanced magnetic resonance imaging (dynamic MRI), superparamagnetic iron oxide (SPIO) (ferucarbotran) MRI and multidetector-row computed tomography (MDCT) and the combination of dynamic MRI plus MDCT vs. dynamic MRI plus SPIO-MRI (double-contrast MRI: DC-MRI) for the detection of small (1 cm and the highest specificity (83.3%) superior to dynamic MRI (p<0.0001). In the per-lesion analysis, SPIO-MRI demonstrated a positive predictive value higher than dynamic MRI (p=0.0059) and than both the combinations dynamic MRI/MDCT and DC-MRI (p=0.0021 and p=0.0087, respectively). DC-MRI showed the highest sensitivity (97.7%) and accuracy (78.9%), detecting hypovascular and atypical HCCs >1 cm. Furthermore its per-patient negative predictive value was the highest (100%), and significantly higher than all the other methods. CONCLUSIONS: DC-MRI is the most sensitive and accurate method and can be confidently used as a single-step procedure for the detection of small HCCs, with the exception of lesions <1 cm.
