COVID-19 lockdown and the rate of central precocious puberty.

PURPOSE: The aim of our study was to compare the incidence of idiopathic central precocious puberty (CPP) in our highly specialized Endocrinological Center before and after the onset of COVID-19 lockdown; we also aimed to identify any potential difference between girls with CPP from the two different time periods. METHODS: We retrospectively analyzed the auxological profile of 49 girls with idiopathic CPP: 30 with pre-lockdown onset and 19 with post-lockdown onset of the disease. We collected patients' characteristics (medical history, physical examination, baseline and dynamic hormonal assessment, bone age, pelvic ultrasound) and compared them between the two groups. RESULTS: We registered an almost threefold increase in CPP incidence in the 2020-2021 period compared to the previous six years. In post-lockdown patients we found a trend for an earlier diagnosis in terms of both chronological age (p 0.0866) and days between the onset of first pubertal signs and diagnosis (p 0.0618). We also found that post-lockdown patients had a significantly lower hypothalamus-pituitary-gonadal axis activation (lower ∆LH% after GnRH test, p 0.0497), a significantly lower increase in bone age calculated at RUS with TW3 method (p 0.0438) and a significantly reduced ovarian activation in females (lower delta-4-androstenedione levels, p 0.0115). Interestingly, post-lockdown patients were born from mothers with an older age at menarche (p 0.0039). CONCLUSIONS: Besides confirming a significant increase in new diagnoses of CPP in the post-lockdown period, our findings among Post-lockdown girls also suggest a less progressive form of CPP and a stronger environmental influence compared to genetic background in determining the timing of pubertal onset.

Sociodemographic profile, health-related behaviours and experiences of healthcare access in Italian transgender and gender diverse adult population.

PURPOSE: Information on the general health of transgender and gender diverse (TGD) individuals continues to be lacking. To bridge this gap, the National Institute of Health in Italy together with the National Office against Racial Discriminations, clinical centres, and TGD organizations carried out a cross-sectional study to define the sociodemographic profile, health-related behaviours, and experiences of healthcare access in Italian TGD adult population. METHODS: A national survey was conducted by Computer-Assisted Web Interviewing (CAWI) technique. Collected data were compared within the TGD subgroups and between TGD people and the Italian general population (IGP). RESULTS: TGD respondents were 959: 65% assigned female at birth (AFAB) and 35% assigned male at birth (AMAB). 91.8% and 8.2% were binary and non-binary TGD respondents, respectively. More than 20% of the TGD population reported to be unemployed with the highest rate detectable in AMAB and non-binary people. Cigarette smoking and binge drinking were higher in the TGD population compared with IGP (p < 0.05), affecting TGD subgroups differently. A significant lower percentage of AFAB TGD people reported having had screening for cervical and breast cancer in comparison with AFAB IGP (p < 0.0001, in both cases). Over 40% was the percentage of AFAB and non-binary TGD people accessing healthcare who felt discriminated against because of their gender identity. CONCLUSIONS: Our results are a first step towards a better understanding of the health needs of TGD people in Italy in order to plan the best policy choices for a more inclusive public health.

The physiological sonographic features of the ovary in healthy subjects: a joint systematic review and meta-analysis by the Italian Society of Gynecology and Obstetrics (SIGO) and the Italian Society of Endocrinology (SIE).

PURPOSE: There is a lack of uniformity in the definition of normal ovary ultrasound parameters. Our aim was to summarize and meta-analyze the evidence on the topic. Full-text English articles published through December 31, 2020 were retrieved via MEDLINE and Embase. Data available for meta-analysis included: ovarian follicular count, ovarian volume, and ovarian Pulsatility Index (PI) assessed by Doppler ultrasound. METHODS: Cohort, cross-sectional, prospective studies with a single or double arm were considered eligible. Interventional studies were included when providing baseline data. Both studies on pre- and post-menopausal women were screened; however, data on menopausal women were not sufficient to perform a meta-analysis. Studies on pre-pubertal girls were considered separately. Eighty-one papers were included in the meta-analysis. RESULTS: The mean ovarian volume was 6.11 [5.81-6.42] ml in healthy women in reproductive age (5.81-6.42) and 1.67 ml [1.02-2.32] in pre-pubertal girls. In reproductive age, the mean follicular count was 8.04 [7.26-8.82] when calculated in the whole ovary and 5.88 [5.20-6.56] in an ovarian section, and the mean ovarian PI was 1.86 [1.35-2.37]. Age and the frequency of the transducers partly modulated these values. In particular, the 25-30-year group showed the higher mean follicular count (9.27 [7.71-10.82]), followed by a progressive age-related reduction (5.67 [2.23-9.12] in fertile women > 35 years). A significant difference in follicular count was also found according to the transducer's upper MHz limit. CONCLUSION: Our findings provide a significant input to improve the interpretation and diagnostic accuracy of ovarian ultrasound parameters in different physiological and pathological settings.

Predictors of reproductive and non-reproductive outcomes of gonadotropin mediated pubertal induction in male patients with congenital hypogonadotropic hypogonadism (CHH).

PURPOSE: To investigate predictors of testicular response and non-reproductive outcomes (height, body proportions) after gonadotropin-induced puberty in congenital hypogonadotropic hypogonadism (CHH). DESIGN: A retrospective analysis of the puberty induction in CHH male patients, undergoing an off-label administration of combined gonadotropin (FSH and hCG). METHODS: Clinical and hormonal evaluations before and during gonadotropin stimulation in 19 CHH patients genotyped by Targeted Next Generation Sequencing for CHH genes; 16 patients underwent also semen analysis after gonadotropins. RESULTS: A lesser increase in testicular volume after 24 months of induction was significantly associated with: (I) cryptorchidism; (II) a positive genetic background; (III) a complete form of CHH. We found no significant correlation with the cumulative dose of hCG administered in 24 months. We found no association with the results of semen analyses, probably due to the low numerosity. Measures of body disproportion (eunuchoid habitus and difference between adult and target height: deltaSDSth), were significantly related to the: (I) age at the beginning of puberty induction; (II) duration of growth during the induction; (III) initial bone age. The duration of growth during induction was associated with previous testosterone priming and to partial forms of CHH. CONCLUSIONS: This study shows that a strong genetic background and cryptorchidism, as indicators of a complete GnRH deficiency since intrauterine life, are negative predictors of testicular response to gonadotropin stimulation in CHH. Body disproportion is associated with a delay in treatment and duration of growth during the induction, which is apparently inversely related to previous androgenization.

Smart drugs: green shuttle or real drug?

We have combined morphological, molecular, and chemical techniques in order to identify the plant and chemical composition of some last-generation smart drugs, present on the market under the following names: Jungle Mistic Incense, B-52, Blendz, and Kratom 10x. Micromorphological analyses of botanical fragments allowed identification of epidermal cells, stomata, trichomes, starch, crystals, and pollen. DNA barcoding was carried out by the plastidial gene rbcL and the spacer trnH-psbA as universal markers. The combination of morphological and molecular data revealed a mixture of plants from different families, including aromatic species, viz., Lamiaceae and Turneraceae. GC-MS and LC-MS analyses on ethanol or methanol extracts showed the presence of synthetic cannabinoids, including JWH-250 in Jungle, JWH-122 in B-52, and JWH-073 and JWH-018 in Blendz. In Kratom 10x, only the indole alkaloid mitragynine was detected. All the identified synthetic cannabinoids, apart from mitragynine, are under the restriction of law in Italy (TU 309/90). Synthetic cannabinoid crystals were also identified by scanning electron microscopy and energy dispersive X-ray spectroscopy, which also detected other foreign organic chemicals, probably preservatives or antimycotics. In Kratom only leaf fragments from Mitragyna speciosa, containing the alkaloid mitragynine, were found. In the remaining products, aromatic plant species have mainly the role of hiding synthetic cannabinoids, thus acting as a "green shuttle" rather than as real drugs. Such a multidisciplinary approach is proposed as a method for the identification of herbal blends of uncertain composition, which are widely marketed in "headshops" and on the Internet, and represent a serious hazard to public health.

Long-term clinical profile of children with the low-penetrance R92Q mutation of the TNFRSF1A gene.

OBJECTIVE: To analyze the long-term impact of the R92Q mutation of TNFRSF1A in children with periodic fever, in comparison with children with tumor necrosis factor receptor-associated periodic syndrome (TRAPS) with TNFRSF1A structural mutations and children with periodic fever of unknown origin fulfilling the criteria for periodic fever, aphthosis, pharyngitis, and adenitis syndrome (PFAPA). METHODS: The extracellular region of TNFRSF1A was analyzed in 720 consecutive children with periodic fever, using denaturing high-performance liquid chromatography and DNA sequencing. Followup data on 11 pediatric patients with TNFRSF1A structural mutations (cysteine or T50M), 23 pediatric patients with an R92Q substitution, and 64 pediatric patients with PFAPA were collected during routine clinic visits. The 50-item Child Health Questionnaire was used to assess health-related quality of life (HRQOL). RESULTS: The frequency of typical TRAPS-related clinical manifestations was significantly lower and the impact of the disease on HRQOL was significantly reduced in patients with the R92Q mutation compared with TRAPS patients carrying structural mutations of TNFRSF1A. Followup data on 11 TRAPS patients with TNFRSF1A structural mutations (mean followup 7.9 years), 16 patients with theR92Q substitution (mean followup 7.3 years), and 64 patients with PFAPA (mean followup 5.2 years) were available. Patients with R92Q mutations and patients with PFAPA displayed a higher rate of self-resolution or amelioration of the fever episodes than did TRAPS patients with structural mutations. CONCLUSION: Although some cases may progress to a more chronic disease course, the majority of children with an R92Q mutation of the TNFRSFA1 gene show a milder disease course than that in children with TNFRSFA1 structural mutations and have a high rate of spontaneous resolution and amelioration of the recurrent fever episodes.

Validation study of the Italian Addenbrooke's Cognitive Examination Revised in a young-old and old-old population.

AIMS: The main aims of the study were the translation and the subsequent validation in Italian of the Addenbrooke's Cognitive Examination Revised (ACE-R), and the evaluation of its usefulness in discriminating cognitively normal subjects from patients with mild dementia in an elderly population. METHODS: The ACE-R was translated and adapted into Italian. The Italian ACE-R was administered to a group of 179 elderly subjects (72 cognitively healthy and 107 subjects with mild dementia, mean age 75.4±6.4 years). The group was stratified into two subsamples according to age, i.e. a young-old (<75 years) and an old-old (≥75 years) group, in order to evaluate the sensitivity and specificity of the test in detecting dementia in different age strata of elderly subjects. RESULTS: The reliability of the Italian ACE-R was extremely good (α-coefficient=0.85). Two different cutoffs were identified for young-old (cutoff 79; sensitivity 90% and specificity 80%) and old-old subjects (cutoff 60; sensitivity 82% and specificity 100%). CONCLUSIONS: The Italian ACE-R is a valid screening tool to detect dementia, especially in the old-old population, which represents not only the fastest growing age group but also the group at the highest risk of dementia in Western countries.

[Severe chloralose intoxication in a toddler]. / Intoxication sévère par le chloralose chez un nourrisson.

UNLABELLED: We report a case of an accidental intoxication in a 20-month-old boy resulting from the ingestion of a rodenticide containing alpha-chloralose. CASE REPORT: Three hours after initial admission to the pediatric emergency department for wheezing bronchitis, this patient was readmitted with a clinical presentation of respiratory insufficiency, a Glasgow coma score of 9 alternating with agitation, areflexia and unilateral mydriasis. Parental interview revealed he had episodes of shaking in the afternoon. Chest x-ray showed thoracic distension. Blood investigations, electrocardiogram, cardiac echography, brain CT scan and CSF were normal. Electroencephalography registered slow delta waves 2-3 cycles/min and an aspect of degraded waves and spikes. The patient was transferred to the intensive care unit where he fully recovered within 48 hours. A second parental interview and clinical presentation confirmed an intoxication with a rodenticide containing alpha-chloralose. The late clinical orientation did not allow us to perform a urinanalysis. DISCUSSION: Clinical association of coma, spontaneous or triggered myoclonias and bronchial hypersecretion are indicative of chloralose intoxication. Presence of specific abnormalities on electroencephalogram and a positive Fujiwara-Ross reaction in an urine sample are additional elements for the diagnosis. The prognosis is usually good after early management which combines gastric lavage, activated charcoal, sedation with benzodiazepines, tracheal intubation and artificial ventilation if required. Severe clinical cases described in voluntary intoxications in adults and teenagers occur very rarely in toddlers.

[Babywalker use (baby-trot, youpala): an unsafe practice]. / Utilisation du trotteur (baby-trot, youpala): une conduite à risque.

AIM: Epidemiological analysis of accidents related to babywalker use admitted to a pediatric emergency department. METHODS: Retrospective, descriptive study of injuries related to babywalkers admitted to the pediatric emergency department between January 1st, 2003 and December 31st, 2005. RESULTS: One hundred and seventy-eight children were admitted due to an accident related to babywalker use. The sex ratio was 1.7 with a male prevalence. Mean age was 11+/-4 months. Seventy-eight percent of babywalker-related injuries were attributable to fall down a flight of stairs. The mean number of steps that a child fell down was 7 (range 1-20 steps). The repartition of accidents was bimodal: during the year, 1 peak in May and 1 in October; during the week: 54% of the cases occurred on Thursday or on the weekend; during the day (1 peak between 10 a.m. and 1 p.m. and 1 peak between 4 p.m. and 7 p.m.). Non-severe head traumas represented the most frequent injury (72%). Twenty-one children were hospitalised for concussion (N=15), cranial fractures (N=3), forearm fracture (N=1), dental subluxation (N=1) and extradural hematoma (N=1). A social problem (families with unsafe domestic practices) was identified in 26 children (15%), 16 of these situations were recognized due to the retrospective character of the study and the analysis of hospital admissions after the first accident. CONCLUSION: Stairway related falls associated with babywalker use and fall down in the stairs are very frequent in children less than 1 year-old. This resulted in babywalkers being prohibited in Canada since 2004. In several countries, advocates are working to ban babywalkers. Active or passive prevention methods have shown their limits. This unsafe and dangerous practice should be banned in France.

[Necrotizing pneumonia and arthritis due to Staphylococcus aureus producing Panton and Valentine leukocidin in a 10-year-old boy]. / Pneumonie nécrosante et ostéoarthrite multifocale à Staphylococcus aureus producteur de la leucocidine de Panton et Valentine chez un garçon de 10 ans.

Staphylococcal necrotizing pneumonia producing the Panton Valentine leukotoxin (PVL) has been described for many years. The french reference center for staphylococcal toxaemia defined it with precision in 1999. A 10-year-old child, died in 36 hours from respiratory distress and shock. Staphylococcal pneumonia was suspected then confirmed: S. Aureus producing PVL was isolated in lung, blood and articulations.

Resection of primary tumor at diagnosis in stage IV-S neuroblastoma: does it affect the clinical course?

PURPOSE: To determine whether resection of primary tumor has a favorable influence on outcome of infants (age 0 to 11 months) with stage IV-S neuroblastoma. PATIENTS AND METHODS: Between March 1976 and December 1993, 97 infants with previously untreated neuroblastoma diagnosed in 21 Italian institutions were classified as having stage IV-S disease. Seventy percent were younger than 4 months. Adrenal was the primary tumor site in 64 of 85 patients with a recognizable primary tumor. Liver was the organ most often infiltrated by the tumor (82 patients), followed by bone marrow and skin. RESULTS: The overall survival (OS) rate at 5 years in 80% and event-free survival (EFS) rate 68%. In 24 infants, the effect of resection of primary tumor could not be evaluated because of rapidly fatal disease progression (n = 8), absence of a primary tumor (n = 12), or partial resection (n = 4). Of 73 assessable patients, 26 underwent primary tumor resection at diagnosis: one died of surgical complications, one relapsed locally and died, and two others relapsed (one of these two locally) and survived, for a 5-year OS rate of 92% and EFS rate of 84%. Of the remaining 47 patients who did not undergo primary tumor resection at diagnosis 11 suffered unfavorable events, of whom five died, for an OS rate of 89% and EFS rate of 75% (no significant difference from previous group). Disease recurred at the primary tumor site in only one five who died, and in only one of six survivors of progression or relapse; in these patients, the primary tumor, located in the mediastinum, was successfully resected. CONCLUSION: Infants who underwent resection of the primary tumor at diagnosis had no better outcome than those in whom the decision was made not to operate.

A cross-sectional nationwide survey on esophageal atresia and tracheoesophageal fistula.

BACKGROUND: Our study aims at disclosing epidemiology and most relevant clinical features of esophageal atresia (EA) pointing to a model of multicentre collaboration. METHODS: A detailed questionnaire was sent to all Italian Units of pediatric surgery in order to collect data of patients born with EA between January and December 2012. The results were crosschecked by matching date and place of birth of the patients with those of diagnosis-related group provided by the Italian Ministry of Health (MOH). RESULTS: A total of 146 questionnaires were returned plus a further 32 patients reported in the MOH database. Basing on a total of 178 patients with EA born in Italy in 2012, the incidence of EA was calculated in 3.33 per 10,000 live births. Antenatal diagnosis was suspected in 29.5% patients. 55.5% showed associated anomalies. The most common type of EA was Gross type C (89%). Postoperative complications occurred in 37% of type C EA and 100% of type A EA. A 9.5% mortality rate was reported. CONCLUSIONS: This is the first Italian cross-sectional nationwide survey on EA. We can now develop shared guidelines and provide more reliable prognostic expectations for our patients.

A new model of integrated home care for the elderly: impact on hospital use.

The objective of the present study was to examine the effect of a home care program based on comprehensive geriatric assessment-Minimum Data Set for Home Care-and case management on hospital use/cost of frail elderly individuals. We determined all hospital admissions and days spent in hospital during the first year since the implementation of the home care program, and compared them to the rate of hospitalization that the same patients had experienced in the year preceding the implementation of such program. Following the implementation of this program, there was a significant reduction of the number of hospitalizations (pre 44% vs. post 26%, P < 0.001), associated with a reduction of hospital days, both at the individual patient level and for each admission. In conclusion, an integrated home care program based on the implementation of a comprehensive geriatric assessment instrument guided by a case manager has a significant impact on hospitalization and is cost-effective.

Sporadic fundic gland polyps: an immunohistochemical study of their antigenic profile.

Fundic Gland Polyps (FGPs) are small sessile (2-5 mm), usually multiple polyps arising in the gastric, acid-secreting mucosa of disputed histogenesis. They have been described in a sporadic form, prevalently in middle aged females, or associated with familial adenomatosis coli-Gardner's syndrome. We performed an immunohistochemical study on 24 sporadic FGPs, using monoclonal antibodies (MAbs) against differentiation markers, class II MHC antigens (HLA-DR), oncofetal and proliferation antigens, aimed to characterize the antigenic profile of the polyps. A preliminary cytogenetic study on five polyps was also done, using an in situ culture method after collagenase treatment. Cytokeratins 8-18 (CAM 5.2 MAb) and 20 (IT-Ks 20.8 MAb), Epithelial Membrane Antigen (EMA) and Chromogranin A were normally expressed by FGPs. FGPs did not express HLA II DR. FGPs did not react with an anti-CEA MAb (F6), but they were frequently positive (22/24, 91.6%) with B72.3 MAb (reacting with the cancer-associated mucin epitope sialyl-Tn). The PC10 MAb (against PCNA or cyclin) showed enhanced expression in the deep glandular-cystic compartment of FGPs; the PCNA index of FGPs was significantly higher than in normal fundic mucosa. The cytogenetic study on the 5 cases analysed, revealed a normal karyotype. We have demonstrated that FGPs express in the paranuclear zone the sialyl-Tn epitope, a side-chain sugar normally masqued in adult gastric mucins, thus revealing an alteration in mucin synthesis; FGPs' higher proliferation index as compared with normal fundic mucosa supports the hypothesis of their hyperproliferative nature.

Features and outcome of neuroblastoma detected before birth.

BACKGROUND/PURPOSE: The growing use of routine ultrasonography during pregnancy is leading to an increasing number of prenatally diagnosed neuroblastomas. Optimal strategy has not yet been defined for these patients, because knowledge on this particular neuroblastoma (NB) population is still limited. However, definite guidelines are needed to avoid inadequate treatment. The authors analyzed the cases of antenatally detected NB (ADNB) reported in the Italian Neuroblastoma Registry during the past 6 years to elucidate the features of this subset of NB. METHODS: The Italian Neuroblastoma Registry was reviewed for the period January 1993 to December 1998 to collect clinical, radiographic, surgical, and histopathological data on ADNB cases. NB stage was evaluated according to INSS criteria. All patients had undergone imaging (computed tomography or magnetic resonance imaging) of the primary tumor and bone marrow biopsy before surgical resection. RESULTS: Seventeen patients were identified. Primary tumour site was adrenal glands in 16 cases and retroperitoneal ganglia in 1. Stage distribution was stage I, 13 cases; stage II-A, 1 case; stage II-B, 1 case; stage IV-S, 2 cases. All cases underwent primary tumour resection. Mean age at surgery was 4 weeks. Resection of primary tumor was radical in 16 cases, partial in 1. All tumors were characterised by favourable histology according to Shimada classification. N-myc gene amplification was studied in 14 patients. N-myc amplification was detected only in a newborn with stage II-A NB, who died of massive bleeding 2 days after tumor resection. DNA index and 1p deletion were studied in 11 and 8 patients, respectively. Both diploidy and deletion of 1p were observed in a newborn who subsequently died of disease progression despite surgery, chemotherapy, and radiation therapy. Fourteen of 17 patients currently are alive and free of disease, and one with IV-S NB and short follow-up is alive with disease. CONCLUSIONS: Our data give evidence that in most cases infants with ADNB represent a subset of patients with excellent outcome. Aggressive treatment may not always be necessary. Infants with ADNB with unfavorable features should undergo early surgical excision, whereas patients with favourable features could be observed awaiting spontaneous regression of the mass, reserving delayed surgery for tumors that increase in size or do not regress.

Cystic nephroma in children. Report of a case.

A case of cystic nephroma is described in a 20-month-old female. The diagnosis of this rare renal pathologic lesion is essentially based on its pathologic features. The treatment consisted of nephrectomy followed by a brief course of chemotherapy. The literature is reviewed with regard to the pathologic features and treatment of this lesion, which has a favorable prognosis.

Adrenocortical tumors in children: a report of 12 cases.

Adrenocortical tumors in children are extremely rare, accounting only for 0.3-0.4% of all neoplasms in this age. Most frequently they secrete hormones, resulting in virilization, Cushing's syndrome or feminization, while the non-functioning ones are unusual. The authors describe 12 cases observed in 13 years (1976-1989), with a mean age of 5 years. 9 cases showed virilization, 4 presented with Cushing's syndrome and in 5 patients an abdominal mass was palpable. One case was affected by Beckwith-Wiedemann's syndrome. I.V. urography was performed in 8 patients, arteriography in 4 and since 1982 all patients were submitted to abdominal sonography and CT scan or MR imaging. Urinary 17-ketosteroids, 17-hydroxycorticoids and serum testosterone and cortisol were tested in all children. Dexamethasone suppression test was performed in 7. All patients were treated with surgery which seems to be the most suitable treatment, while the real effectiveness of treatment by drug therapy with suppressors of steroidogenesis is not confirmed in children. Histopathological examination showed typical features of adenoma in 5 cases, of adenocarcinoma in 4, while three cases revealed border line forms classified as "atypical adenomas". At the moment 10 patients are alive with a follow-up ranging from 18 months to 14 years, while 2 children with adenocarcinoma are dead.

Esophageal leiomyomatosis in children: report of a case and review of the literature.

The authors describe a case of a 5-years-old girl affected by diffuse oesophageal leiomyomatosis presenting with progressive dysphagia, cyanosis, recurrent pneumonia and retrosternal pain. She also suffered from occasional constipation due to perineal involvement by the disease and had a past history of recurrent microscopic hematuria, suggesting an association with an Alport-like syndrome. Only 24 cases of esophageal leiomyomatosis could be found in the medical literature in children aged less than 14 years, confirming the rarity of the disease. A clinical analysis of all cases reviewed from the literature is made, stressing the importance of an accurate preoperative diagnosis for the choice of proper surgical treatment to avoid recurrence.

Pleuropulmonary blastoma in congenital cystic adenomatoid malformation: report of a case.

Pulmonary blastoma is a rare malignant tumor seen in both adults and children. Approximately only 25% of cases occur in pediatric patients, many of whom affected by a congenital pulmonary cystic lesion. The clinical features, radiological findings and management of a 3-year-old boy affected by a pulmonary blastoma which arose in a congenital cystic adenomatoid malformation are reported, and an extensive review of the literature is also made. Because of the well-known tendency of cystic pulmonary diseases to develop malignancies, authors recommend the surgical excision of these kind of lesion or at least their close radiological follow-up.
