Pediatric vulvar lichen sclerosus: Does it resolve or does it persist after menarche?

Background and Objectives

Although data regarding the rates of remission and progression of the disease are still scarce, it is generally now acknowledged that pediatric vulvar lichen sclerosus (pVLS) can persist beyond puberty. Recent studies reveal that this condition may persist in as many as 75% of cases. The present study aims to answer the following query: how does pVLS evolve after menarche?

Methods

This observational retrospective study conducted on premenarchal girls diagnosed with pVLS in our institution between 1990 and 2011 describes 31 patients who returned for multidisciplinary clinical evaluation following menarche.

Results

The mean follow-up time was 14 years. At the post-menarche clinical examination, patients were classified as follows: 58% were still affected by VLS, 16% presented with a complete remission of disease, and 26% were completely asymptomatic although with persistent clinical signs of VLS.

Conclusions

In our series, pVLS persists following menarche in the majority of patients. These findings suggest the importance of a long-term follow-up even among patients who report resolution of symptoms following menarche.     

Promoting weight loss and psychological well-being in patients with obesity: A sequential combination of behavioural lifestyle intervention and well-being therapy

Behavioural lifestyle interventions focused on diet and physical activity are a cornerstone for the treatment of obesity. However, their effects vary substantially across individuals in terms of magnitude and durability. Personalized approaches that target psychological well-being may be promising to facilitate healthy behaviours and sustained weight loss. This preliminary study aimed to explore whether the sequential combination of behavioural lifestyle intervention (BLI) and well-being therapy (WBT) may result in more favourable outcomes than BLI alone in promoting weight loss (primary outcome) and improving psychological well-being, distress, dietary behaviours and physical activity (secondary outcomes). A total of 83 patients with obesity were randomly assigned to BLI/WBT (N = 38) or BLI group (N = 45). The BLI group received a 12-week behavioural weight loss programme, whereas the BLI/WBT group received the same programme followed by an additional 4-week WBT, adapted for group interventions. Data were collected at pretreatment (baseline, T1), at the end of BLI/WBT (T2), at 6-month (T3) and 12-month (T4) follow-ups. There was a significant weight loss in both treatment groups at T2, T3 and T4. The BLI/WBT group showed greater improvements in depressive symptoms at T3 and T4, in autonomy at T2, in personal growth at T4 and in global well-being at T4 compared with BLI group. WBT yielded no additional effect on weight loss. However, the secondary outcomes indicate that WBT may have enduring effects that reduce vulnerability to psychological distress in patients with obesity. In order to confirm these preliminary findings and explore whether a more intensive and individualized WBT can foster sustained weight loss, future studies are needed.     

Further characterization of NFIB-associated phenotypes: Report of two new individuals

Nuclear Factor I B (NFIB) haploinsufficiency has recently been identified as a cause of intellectual disability (ID) and macrocephaly. Here we report on two new individuals carrying a microdeletion in the chromosomal region 9p23-p22.3 containing NFIB. The first is a 7-year 9-month old boy with developmental delays, ID, definite facial anomalies, and brain and spinal cord magnetic resonance imaging findings including periventricular nodular heterotopia, hypoplasia of the corpus callosum, arachnoid cyst in the left middle cranial fossa, syringomyelia in the thoracic spinal cord and distal tract of the conus medullaris, and a stretched appearance of the filum terminale. The second is a 32-year-old lady (the proband' mother) with dysmorphic features, and a history of learning disability, hypothyroidism, poor growth, left inguinal hernia, and panic attacks. Her brain magnetic resonance imaging findings include a dysmorphic corpus callosum, and a small cyst in the left choroidal fissure that marks the hippocampal head. Array-based comparative genomic hybridization identified, in both, a 232 Kb interstitial deletion at 9p23p22.3 including several exons of NFIB and no other known genes. Our two individuals add to the knowledge of this rare disorder through the addition of new brain and spinal cord MRI findings and dysmorphic features. We propose that NFIB haploinsufficiency causes a clinically recognizable malformation-ID syndrome.     

Prognostic value of non-invasive scores based on liver stiffness measurement,spleen diameter and platelets in HIV-infected patients

Background and Aims

People living with HIV (PLWH) are at high risk for advanced chronic liver disease and related adverse outcomes. We aimed to validate the prognostic value of non-invasive scores based on liver stiffness measurement (LSM) and on markers of portal hypertension (PH), namely platelets and spleen diameter, in PLWH.

Methods

We combined data from eight international cohorts of PLWH with available non-invasive scores, including LSM and the composite biomarkers liver stiffness-spleen size-to-platelet ratio score (LSPS), LSM-to-Platelet ratio (LPR) and PH risk score. Incidence and predictors of all-cause mortality, any liver-related event and classical hepatic decompensation were determined by survival analysis, controlling for competing risks for the latter two. Non-invasive scores were assessed and compared using area under the receiver operating curve (AUROC).

Results

We included 1695 PLWH (66.8% coinfected with hepatitis C virus). During a median follow-up of 4.7 (interquartile range 2.8–7.7) years, the incidence rates of any liver-related event, all-cause mortality and hepatic decompensation were 13.7 per 1000 persons-year (PY) (95% confidence interval [CI], 11.4–16.3), 13.8 per 1000 PY (95% CI, 11.6–16.4) and 9.9 per 1000 PY (95% CI, 8.1–12.2), respectively. The AUROC of LSM was similar to that of the composite biomarkers, ranging between 0.83 and 0.86 for any liver-related event, 0.79–0.85 for all-cause mortality and 0.87–0.88 for classical hepatic decompensation. All individual non-invasive scores remained independent predictors of clinical outcomes in multivariable analysis.

Conclusions

Non-invasive scores based on LSM, spleen diameter and platelets predict clinical outcomes in PLWH. Composite biomarkers do not achieve higher prognostic performance compared to LSM alone.     

Impact of an optimized epilepsy surgery imaging protocol for focal epilepsy: A monocentric prospective study

Objective

To evaluate in a real clinical scenario the impact of the ILAE-recommended “Harmonized neuroimaging of epilepsy structural sequences”- HARNESS protocol in patients affected by focal epilepsy.

Methods

We prospectively enrolled focal epilepsy patients who underwent a structural brain MRI between 2020 and 2021 at Modena University Hospital. For all patients, MRIs were: (a) acquired according to the HARNESS-MRI protocol (H-MRI); (b) reviewed by the same neuroradiology team. MRI outcomes measures were: the number of positive (diagnostic) and negative MRI; the type of radiological diagnosis classified in: (1) Hippocampal Sclerosis; (2) Malformations of cortical development (MCD); (3) Vascular malformations; (4) Glial scars; (5) Low-grade epilepsy-associated tumors; (6) Dual pathology. For each patient we verified for previous MRI (without HARNESS protocol, noH-MRI) and the presence of clinical information in the MRI request form. Then the measured outcomes were reviewed and compared as appropriate.

Results

A total of 131 patients with H-MRI were included in the study. 100 patients out from this cohort had at least one previous noH-MRI scan. Of those, 92/100 were acquired at the same Hospital than H-MRI and 71/92 on a 3T scanner. The HARNESS protocol revealed 81 (62%) positive and 50 (38%) negative MRI, and MCD was the most common diagnosis (60%). Among the entire pool of 100 noH-MRI, 36 resulted positive with a significant difference (p < .001) compared to H-MRI. Similar findings were observed when accounting for the expert radiologists (H-MRI = 57 positive; noH-MRI = 33, p < .001) and the scanner field strength (H-MRI 43 = positive, noH-MRI = 23, p < .001), while clinical information were more present in H-MRI (p < .002).

Significance

The adoption of a standardized and optimized MRI acquisition protocol together with adequate clinical information contribute to identify a higher number of potentially epileptogenic lesions (especially FCD) thus impacting concretely on the clinical management of patients with focal epilepsy.
