Acute cholecystitis management in high-risk, critically ill, and unfit-for-surgery patients: the Italian Society of Emergency Surgery and Trauma (SICUT) guidelines.

Dealing with acute cholecystitis in high-risk, critically ill, and unfit-for-surgery patients is frequent during daily practice and requires complex management. Several procedures exist to postpone and/or prevent surgical intervention in those patients who temporarily or definitively cannot undergo surgery. After a systematic review of the literature, an expert panel from the Italian Society of Emergency Surgery and Trauma (SICUT) discussed the different issues and statements in subsequent rounds. The final version of the statements was discussed during the annual meeting in Rome (September 2022). The present paper presents the definitive conclusions of the discussion. Fifteen statements based on the literature evidence were provided. The statements gave precise indications regarding the decisional process and the management of patients who cannot temporarily or definitively undergo cholecystectomy for acute cholecystitis. Acute cholecystitis management in high-risk, critically ill, and unfit-for-surgery patients should be multidisciplinary. The different gallbladder drainage methods must be tailored according to each patient and based on the expertise of the hospital. Percutaneous gallbladder drainage is recommended as the first choice as a bridge to surgery or in severely physiologically deranged patients. Endoscopic gallbladder drainage (cholecystoduodenostomy and cholecystogastrostomy) is suggested as a second-line alternative especially as a definitive procedure for those patients not amenable to surgical management. Trans-papillary gallbladder drainage is the last option to be reserved only to those unfit for other techniques. Delayed laparoscopic cholecystectomy in patients with percutaneous gallbladder drainage is suggested in all those patients recovering from the conditions that previously discouraged surgical intervention after at least 6 weeks from the gallbladder drainage.

Recommendations for the management of acute immune thrombocytopenia in children. A Consensus Conference from the Italian Association of Pediatric Hematology and Oncology.

BACKGROUND: Immune thrombocytopenia (ITP) is an acquired immune-mediated bleeding disorder characterized by isolated thrombocytopenia. Its estimated yearly incidence in the pediatric population is 1.9-6.4/100,000. ITP in children is usually a self-limiting and benign disorder. The clinical management of children with ITP often remains controversial, as robust randomized trials on the management of this disorder are lacking. Treatments vary widely in clinical practice and existing guidelines from hematology societies on clinical management offer indications based largely on expert opinion rather than strong evidence. MATERIALS AND METHODS: The Coagulative Disorder Working Group of the Italian Association of Pediatric Hematology and Oncology (AIEOP) developed this document to collect shared expert opinions on the management of newly diagnosed ITP, updating previous guidelines and providing recommendations to pediatricians. Each statement has been given a score expressing the strength of evidence, appropriateness and agreement among participants. RESULTS: Clear-cut definitions of the clinical phases of the disease and clinical response are stated. Recommendations are given regarding the classification of bleeding symptoms, evaluation of bleeding risk, diagnosis, and prognostic factors. Specific recommendations for treatment include indications for first-line (intravenous immunoglobulins, steroids) and second-line (combined therapy, thrombopoietin receptor agonists, immunosuppressive drugs, rituximab) therapeutic agents, as well as hemorrhagic emergency and supportive treatment, including emergency splenectomy. The optimal follow-up schedule, the relation between ITP and vaccines and health-related quality-of-life issues are also discussed. DISCUSSION: The panel achieved broad consensus on issues related to how to treat children with newly diagnosed ITP, providing a comprehensive review of all relevant clinical aspects.

Long term use of eltrombopag in children with chronic immune thrombocytopenia: extended real life retrospective multicenter experience of the Italian Association of Pediatric Hematology and Oncology.

Background: The present multicenter retrospective study on eltrombopag administration in Italian children with chronic ITP aims to extend follow-up of our previous study. Materials and methods: This retrospective multicenter study was conducted in 17 centers affiliated to the Italian Association of Pediatric Hematology and Oncology (AIEOP). Patients were classified into three subgroups: group 1 included patients who discontinued treatment due to a stable platelet count; group 2 included patients who discontinued treatment due to ineffectiveness; group 3 included patients who did not permanently discontinue treatment. Results: 56 patients were eligible for analysis. The median duration of eltrombopag treatment was 40 months (7-71 months). Twenty patients (36%) discontinued permanently eltrombopag. The reasons of permanent discontinuation were adverse effects (n = 1), inefficacy (n = 10), stable platelet count (n = 9). All patients of group 1 maintained a durable response without additional treatments after eltrombopag discontinuation. We found that patients of group 2 were on treatment for less time (median treatment time: 13.5 months, min: 6.0 - max: 56.0) than patients of group 1 (median treatment time: 34 months, min: 16.0 - max: 62.0) (p < 0.05). Patients of group 2 mostly did not achieve a stable platelet count in the first 6 months of treatment and underwent concomitant therapies during follow-up respect of group 1 and group 3 (p < 0.01). Conclusion: Our study found that the benefits of eltrombopag treatment, in terms of platelet count improvement and use of additional therapies, are identifiable from the first 6 months of treatment.

Quick drop of platelet counts in children with chronic immune thrombocytopenia after COVID-19 mRNA vaccination: case reports.

Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by isolated thrombocytopenia. Many viruses and some vaccines have been identified as triggering the autoimmune process, including parvovirus, human immunodeficiency virus, Epstein-Barr virus, rubella, and measles. However, ITP in association with coronavirus disease 2019 (COVID-19) vaccination has not been reported so far. We describe the cases of two young girls affected by ITP presenting a quick reduction of platelet count after receiving Pfizer-BioNTech COVID-19 vaccine.

Successful Eltrombopag Therapy in a Child with MYH9-Related Inherited Thrombocytopenia.

Inherited thrombocytopenias represents a heterogenous group of diseases characterized by a congenital reduction in the platelet count that could lead to a bleeding tendency. MYH9-related disorders are characterized by large platelets and congenital thrombocytopenia. Thrombopoietin-receptor agonists: eltrombopag and romiplostim are currently approved in many countries for the treatment of different forms of acquired thrombocytopenia, such as immune thrombocytopenia. We report, instead, the successful use of eltrombopag to treat inherited thrombocytopenia in a patient with an MHY9-related disease. This is the first report of a chronic use of eltrombopag to elevate platelets in MYH9-related disorders without side effects.

Evaluation of the efficacy and safety of deferiprone compared with deferasirox in paediatric patients with transfusion-dependent haemoglobinopathies (DEEP-2): a multicentre, randomised, open-label, non-inferiority, phase 3 trial.

BACKGROUND: Transfusion-dependent haemoglobinopathies require lifelong iron chelation therapy with one of the three iron chelators (deferiprone, deferasirox, or deferoxamine). Deferasirox and deferiprone are the only two oral chelators used in adult patients with transfusion-dependent haemoglobinopathies. To our knowledge, there are no randomised clinical trials comparing deferiprone, a less expensive iron chelator, with deferasirox in paediatric patients. We aimed to show the non-inferiority of deferiprone versus deferasirox. METHODS: DEEP-2 was a phase 3, multicentre, randomised trial in paediatric patients (aged 1 month to 18 years) with transfusion-dependent haemoglobinopathies. The study was done in 21 research hospitals and universities in Italy, Egypt, Greece, Albania, Cyprus, Tunisia, and the UK. Participants were receiving at least 150 mL/kg per year of red blood cells for the past 2 years at the time of enrolment, and were receiving deferoxamine (<100 mg/kg per day) or deferasirox (<40 mg/kg per day; deferasirox is not registered for use in children aged <2 years so only deferoxamine was being used in these patients). Any previous chelation treatment was permitted with a 7-day washout period. Patients were randomly assigned 1:1 to receive orally administered daily deferiprone (75-100 mg/kg per day) or daily deferasirox (20-40 mg/kg per day) administered as dispersible tablets, both with dose adjustment for 12 months, stratified by age (<10 years and ≥10 years) and balanced by country. The primary efficacy endpoint was based on predefined success criteria for changes in serum ferritin concentration (all patients) and cardiac MRI T2-star (T2*; patients aged >10 years) to show non-inferiority of deferiprone versus deferasirox in the per-protocol population, defined as all randomly assigned patients who received the study drugs and had available data for both variables at baseline and after 1 year of treatment, without major protocol violations. Non-inferiority was based on the two-sided 95% CI of the difference in the proportion of patients with treatment success between the two groups and was shown if the lower limit of the two-sided 95% CI was greater than -12·5%. Safety was assessed in all patients who received at least one dose of study drug. This study is registered with EudraCT, 2012-000353-31, and ClinicalTrials.gov, NCT01825512. FINDINGS: 435 patients were enrolled between March 17, 2014, and June 16, 2016, 393 of whom were randomly assigned to a treatment group (194 to the deferiprone group; 199 to the deferasirox group). 352 (90%) of 390 patients had ß-thalassaemia major, 27 (7%) had sickle cell disease, five (1%) had thalassodrepanocytosis, and six (2%) had other haemoglobinopathies. Median follow-up was 379 days (IQR 294-392) for deferiprone and 381 days (350-392) for deferasirox. Non-inferiority of deferiprone versus deferasirox was established (treatment success in 69 [55·2%] of 125 patients assigned deferiprone with primary composite efficacy endpoint data available at baseline and 1 year vs 80 [54·8%] of 146 assigned deferasirox, difference 0·4%; 95% CI -11·9 to 12·6). No significant difference between the groups was shown in the occurrence of serious and drug-related adverse events. Three (2%) cases of reversible agranulocytosis occurred in the 193 patients in the safety analysis in the deferiprone group and two (1%) cases of reversible renal and urinary disorders (one case of each) occurred in the 197 patients in the deferasirox group. Compliance was similar between treatment groups: 183 (95%) of 193 patients in the deferiprone group versus 192 (97%) of 197 patients in the deferisirox group. INTERPRETATION: In paediatric patients with transfusion-dependent haemoglobinopathies, deferiprone was effective and safe in inducing control of iron overload during 12 months of treatment. Considering the need for availability of more chelation treatments in paediatric populations, deferiprone offers a valuable treatment option for this age group.

Use of Eltrombopag in Children With Chronic Immune Thrombocytopenia (ITP): A Real Life Retrospective Multicenter Experience of the Italian Association of Pediatric Hematology and Oncology (AIEOP).

Background: The thrombopoietin receptor agonist eltrombopag has been shown to be safe and effective for children with chronic immune thrombocytopenia (ITP). The aim of the present study was to characterize eltrombopag use in current clinical practice. Material and Methods: This is a retrospective multicenter study conducted in 17 centers affiliated to the Italian Association of Pediatric Hematology and Oncology (AIEOP). The primary objective of the study was to determine the prevalence of eltrombopag use in Italian children affected by chronic ITP, after EMA authorization for pediatric age. The secondary objective was to assess efficacy in the first 6 months and safety during the whole period of eltrombopag treatment in current clinical practice. A total of 386 children with chronic ITP were retrospectively enrolled and eligible for analysis. Among these patients, 71 received eltrombopag. Results: The prevalence of eltrombopag use was 19% (95% CI 0.15-0.23). Thirty-one patients (44%) were male and 40 patients (56%) were female. The median age at the first dose of eltrombopag was 12 years (3-17 years). The median duration of eltrombopag treatment was 11 months (1-32 months) and the median starting dose was 50 mg/day (12, 5-75 mg/day). Thirty-two patients (45%) required one or more concomitant ITP medications during the first 6 months of treatment with eltrombopag. Thirty-nine patients (55%) never required concomitant medications. Median platelet counts and proportion of patients achieving the target platelet count of at least 30 × 109/L and 100 × 109/L significantly increased during the first 6 months of treatment (p < 0.0001). Additionally, eltrombopag has been proved effective in the absence of concomitant therapies. The most common Adverse Events were headache (7%) and thrombocytosis (6%). Conclusion: Our study highlighted the crucial role of eltrombopag as second line treatment in children with chronic ITP.

Serum Vitamin D Levels in Children with Immune Thrombocytopenia.

OBJECTIVE: Immune thrombocytopenia (ITP) is an acquired immuno-mediated disorder characterized by thrombocytopenia with an increased risk of bleeding. In recent years 1,25[OH]2D3 has been rediscovered as an immune modulator. We decided to evaluate serum Vitamin D levels in a cohort of children with immune thrombocytopenia in order to discover if Vitamin D concentrations may predict ITP duration. METHODS: Thirty children were enrolled in this study (sixteen with chronic ITP and fourteen with newly diagnosed ITP) to assess serum Vitamin D levels. RESULTS: The results showed that 80% of the enrolled children presented a D hypovitaminosis status. Children with newly diagnosis ITP showed no statistically significantly higher median values of Vitamin D compared to chronic ITP. CONCLUSION: This study may suggest that Vitamin D deficiency does not represent a chronicity factor for ITP. However, further studies are needed to understand the role of Vitamin D in ITP pathogenesis.

HbS/ß+ thalassemia: Really a mild disease? A National survey from the AIEOP Sickle Cell Disease Study Group with genotype-phenotype correlation.

OBJECTIVES: HbS/ß+ patients' presence in Italy increased due to immigration; these patients are clinically heterogeneous, and specific guidelines are lacking. Our aim is to describe a cohort of HbS/ß+ patients, with genotype-phenotype correlation, in order to offer guidance for clinical management of such patients. METHODS: Retrospective cohort study of HbS/ß+ patients among 15 AIEOP Centres. RESULTS: A total of 41 molecularly confirmed S/ß+ patients were enrolled (1-55 years, median 10.9) and classified on ß+ mutation: IVS-I-110, IVS-I-6, promoter, and "others." Prediagnostic events included VOC 16/41 (39%), ACS 6/41 (14.6%), sepsis 3/41 (3.7%), and avascular necrosis 3/41 (7,3%). Postdiagnostic events were VOC 22/41 (53.6% %), sepsis 4/41 (9.7%), ACS 4/41 (9.7%), avascular necrosis 3/41 (7.3%), aplastic crisis 2/41 (4.8%), stroke 1/41 (2.4%), ACS 1/41 (2.4%), and skin ulcerations 1/41 (2.4%). The IVS-I-110 group presented the lowest median age at first SCD-related event (P = .02 vs promoter group) and the higher median number of severe events/year (0.26 events/patient/year) (P = .01 vs IVS-I-6 and promoter groups). Promoter group presented a specific skeletal phenotype. Treatment regimen applied was variable among the centers. CONCLUSIONS: HbS/ß+ is not always a mild disease. Patients with IVS-I-110 mutation could benefit from a standard of care like SS and S/ß° patients. Standardization of treatment is needed.

Hydroxyurea prescription, availability and use for children with sickle cell disease in Italy: Results of a National Multicenter survey.

BACKGROUND: The number of patients with sickle cell disease (SCD) has increased in Italy in the past decade due to immigration. In spite of the established efficacy of hydroxyurea (HU) in childhood, population-based data regarding its prescription and effectiveness come mainly from studies performed in adults or outside Europe. POPULATION AND METHODS: The Hydroxyurea in SCD: A Large Nation-wide Cohort Study from Italy was a retrospective cohort study of adult and pediatric patients with SCD attending 32 centers. Pediatric data are analyzed separately. RESULTS: Out of 504 children followed in 11 centers, 206 (40%) were on HU (194 SS/Sß°, 12 SC/Sß+); 74% came from Sub-Saharian Africa and 18% from Europe. HU therapy indications for SS/Sß° patients were as follows: 57% painful vaso-occlusive crisis, acute chest syndrome or both, 24% anemia, 8% anemia, and other reasons (the majority had Hb ≤ 8-8.5 g/dl, revealing scarce acceptance of low Hb values by pediatric hematologist). Mean starting dose was 15.5 mg/kg, and dose at full regimen was 17.1 mg/kg. Mean age at HU therapy was 7.68 years, although it was lower for SS/Sß° patients. Only 10% started HU before 3 years. In 92%, 500 mg capsule was used; in 6%, the galenic was used; and in 2%, 100 mg tablet was used. Significant reduction of clinical events and inpatients admissions, with improvement in hematological parameters, was observed for SS/Sß° patients and a trend toward improvement for SC/Sß+ patients was also observed. CONCLUSIONS: HU effectiveness is demonstrated in a national cohort of children with SCD living in Italy, even at a lower dose than recommended, revealing good adherence to a treatment program by a socially vulnerable group of patients such as immigrants.

Pattern of complications and burden of disease in patients affected by beta thalassemia major.

OBJECTIVES: Despite the correct application of blood transfusions and chelation treatments, beta thalassemia patients have many complications. Systematic population analyses on types and frequency of these complications are very few. The aim of this study is to characterize the complications, their risk factors and their clinical and economic impact. METHODS: Complications at baseline and events occurring during one observational year were analyzed in 272 patients aged >12 years. Risk factors were analyzed through chi-squared and unpaired t tests. Logistic regression was applied to perform the risk factors multivariate analysis. RESULTS: A total of 554 complications (1-6 per patient) affected 82.3% of patients. Cardiac complications were less represented than expected. Musculoskeletal diseases were the most represented complications followed by hepatic, sexual and endocrine diseases. Splenectomized patients, born before 1970 and aged >40 years, starting iron chelation therapy when aged >4 years or after receiving more than 20 blood transfusions, presented a significantly higher number of complications. A total of 885 adverse events requiring 34125 additional medical services occurred in 1 year. Of these, 34.9% were related to treatments and 65.1% to other causes. Event numbers, additional medical interventions and cost increased progressively in patients affected by one or more complication compared to patients with no complications. CONCLUSIONS: The pattern of complications changes according to birth cohort and differentiates older from younger patients. The burden of the disease and its costs increase after the onset of the first complication, therefore prevention of complications is fundamental in these patients.

Diagnosis and management of newly diagnosed childhood autoimmune haemolytic anaemia. Recommendations from the Red Cell Study Group of the Paediatric Haemato-Oncology Italian Association.

Autoimmune haemolytic anaemia is an uncommon disorder to which paediatric haematology centres take a variety of diagnostic and therapeutic approaches. The Red Cell Working Group of the Italian Association of Paediatric Onco-haematology (Associazione Italiana di Ematologia ed Oncologia Pediatrica, AIEOP) developed this document in order to collate expert opinions on the management of newly diagnosed childhood autoimmune haemolytic anaemia.The diagnostic process includes the direct and indirect antiglobulin tests; recommendations are given regarding further diagnostic tests, specifically in the cases that the direct and indirect antiglobulin tests are negative. Clear-cut definitions of clinical response are stated. Specific recommendations for treatment include: dosage of steroid therapy and tapering modality for warm autoimmune haemolytic anaemia; the choice of rituximab as first-line therapy for the rare primary transfusion-dependent cold autoimmune haemolytic anaemia; the indications for supportive therapy; the need for switching to second-line therapy. Each statement is provided with a score expressing the level of appropriateness and the agreement among participants.

Population pharmacokinetics and dosing recommendations for the use of deferiprone in children younger than 6 years.

AIMS: Despite long clinical experience with deferiprone, there is limited information on its pharmacokinetics in children aged <6 years. Here we assess the impact of developmental growth on the pharmacokinetics of deferiprone in this population using a population approach. Based on pharmacokinetic bridging concepts, we also evaluate whether the recommended doses yield appropriate systemic exposure in this group of patients. METHODS: Data from a study in which 18 paediatric patients were enrolled were available for the purposes of this analysis. Patients were randomised to three deferiprone dose levels (8.3, 16.7 and 33.3 mg kg-1 ). Blood samples were collected according to an optimised sampling scheme in which each patient contributed to a maximum of five samples. A population pharmacokinetic model was developed using NONMEM v.7.2. Model selection criteria were based on graphical and statistical summaries. RESULTS: A one-compartment model with first-order absorption and first-order elimination best described the pharmacokinetics of deferiprone. Drug disposition parameters were affected by body weight, with both clearance and volume increasing allometrically with size. Simulation scenarios show that comparable systemic exposure (AUC) is achieved in children and adults after similar dose levels in mg kg-1 , with median (5-95th quantiles) AUC values, respectively, of 340.6 (223.2-520.0) µmol l-1  h and 318.5 (200.4-499.0) µmol l-1  h at 75 mg kg-1 day-1 , and 453.7 (297.3-693.0) µmol l-1  h and 424.2 (266.9-664.0) µmol l-1  h at 100 mg kg-1  day-1 given as three times daily (t.i.d.) doses. CONCLUSIONS: Based on the current findings, a dosing regimen of 25 mg kg-1  t.i.d. is recommended in children aged <6 years, with the possibility of titration up to 33.3 mg kg-1  t.i.d.

The Italian multiregional thalassemia registry: Centers characteristics, services, and patients' population.

OBJECTIVES: The prognosis of beta-Thalassemia major and other congenital hemoglobinopathies has profoundly changed over the last decades. Moreover, only few countries in Europe provide dedicated services and the description of the measures for patients monitoring and treatment is overall very scarce. The HTA-Thal project is aimed to identify the services available in Italy and to collect epidemiological and clinical data on the thalassemic population (HTA-Thal Registry). METHODS: A map of the existing centers was created and two electronic questionnaires were completed with information on the services and patients. RESULTS: On 182 centers identified, 60 completed the two questionnaires. Centers resulted to be extremely heterogeneous in terms of size, age of patients in care, and services availability. The transition of pediatric patients to adult centers was not guaranteed. Thousand eight hundred and seventy-three beta-Thalassemia major patients (of which 259 pediatrics), regularly transfused, were registered. Deferasirox is the most used chelator as monotherapy (616 patients) and its use prevails in younger patients. A higher number of patients (847 patients) use Deferoxamine, either alone (448 patients) or in combination with DFP (399 patients), while 782 patients use Deferiprone alone (383 patients) or in combination (399 patients). 31.6 and 66.6% of centers were not equipped for specialized visits or local MRI, respectively. Centers with 30-80 patients show the high percentage of patients appropriately monitored when compared to smaller or bigger centers. CONCLUSIONS: This analysis confirms the importance of patients' registries for the collection of large datasets and the need for dedicated 'specialized centers' equipped to provide the best standard treatment to patients.

Model-Based Optimisation of Deferoxamine Chelation Therapy.

PURPOSE: Here we show how a model-based approach may be used to provide further insight into the role of clinical and demographic covariates on the progression of iron overload. The therapeutic effect of deferoxamine is used to illustrate the application of disease modelling as a means to characterising treatment response in individual patients. METHODS: Serum ferritin, demographic characteristics and individual treatment data from clinical routine practice on 27 patients affected by ß-thalassaemia major were used for the purposes of this analysis. The time course of serum ferritin was described by a hierarchical nonlinear mixed effects model, in which compliance was parameterised as a covariate factor. Modelling and simulation procedures were implemented in NONMEM (7.2.0). RESULTS: A turnover model best described serum ferritin changes over time, with the effect of blood transfusions introduced on the ferritin conversion rate and the effect of deferoxamine on the elimination parameter (Kout) in a proportional manner. The results of the simulations showed that poor quality of execution is preferable over drug holidays; and that independently of the compliance pattern, the therapeutic intervention is not effective if >60% of the doses are missed. CONCLUSIONS: Modelling of ferritin response enables characterisation of the dynamics of iron overload due to chronic transfusion. The approach can be used to support decision making in clinical practice, including personalisation of the dose for existing and novel chelating agents.

The role of laparoscopy in recurrent right lower quadrant pain in children.

According to scientific literature, laparoscopy as aid in diagnosis and therapy for chronic pain in the right iliac quadrant shows a undeniable advantage thanks to its mini-invasiveness, the possibility of a methodical and thorough exploration of the entire abdominal cavity in those cases of recurrent pain, emotionally and socially debilitating, that do not find an answer in the usual etiological diagnostic clinical-instrumental. In those cases in which any significant organic pathology that justifies the recurring pain in the right iliac fossa is found during laparoscopic exploration, it has been seen that it is useful to perform appendectomy anyway, that leads to the disappearance of symptoms, which are probably due to inflammatory recurrent catarrhal phenomena of appendix in such patients, as it is demonstrated by the adhesions found at cecum-appendicular level. From January 2011 to December 2013, 24 children with chronic recurrent right lower quadrant pain were subjected to diagnostic laparoscopy. Ages varied from 11 to 18 years (mean, 14 years). There were 6 males and 18 females. Laparoscopic findings included macroscopical signs of acute appendicitis in 15 patients; cecal adhesions in 20 patients, kink of the appendix in 3. The abdominal pain completely resolved in all the patients following laparoscopy.

Chronic immune thrombocytopenia in childhood.

Chronic thrombocytopenias are pathological conditions defined as a persistent platelet count below the normal range for more than 6-12 months, clinically characterized by mucocutaneous bleeding. Recently, an International Working Group of expert clinicians has redefined standard terminology and definitions of primary and secondary chronic immune thrombocytopenia (ITP). A document issued on acute childhood idiopathic thrombocytopenic purpura (AIEOP) provides parents and physicians with guidelines for the management of chronic ITP and gives prominence to the periodic re-evaluation of differential diagnosis. The majority of chronic ITP children do not require pharmacological treatments, especially if symptoms are absent or minimal and the treatment decision depends on several factors, in particular clinical conditions rather than platelets count. The recommendations distinguish three therapeutic strategies: emergency or symptomatic treatment, maintenance therapy and treatment aiming at definitive remission. Experimental/off-label treatment of chronic ITP are reported in the literature, such as the use of rituximab. Currently, other drugs (thrombopoiesis stimulating factors, mycophenolate, dapsone, danazol, azathioprine, rFVIIa, cyclophosphamide, vinca alkaloids and cyclosporine) are recommended in special cases or trials.

Megacolon for a giant faecaloma with unlucky outcome: case report and review of the literature.

We herein report a case of megacolon with fecaloma in an 83-year-old man who presented with constipation, no intestinal occlusion, and a left hydroureteronephrosis, with A.S.A. 4. The patient asymptomatic, was treated Primariely with laxatives. During the conservative therapy the patient presented an abrupt abdominal distension with a bowel obstruction and abdominal compartment syndrome. After the laparotopy and a Hartmann left colon resection the patient died for cardiovascular and metabolic complications. The aim of this report is to give a brief review of this entity and discuss the treatment options for these cases.
