Infantile systemic hyalinosis: Variable grades of severity.

BACKGROUND: Infantile systemic hyalinosis (ISH) is an autosomal recessively inherited disorder. The classical natural history of the disease is characterised by hypotonia, multiple contractures, skin lesions, osteopenia, joint pain, bone fractures, persistent diarrhoea and growth deficiency. MATERIALS AND METHODS: Two children manifested the severe type of ISH underwent genotypic confirmation. In order to identify which other family members have inherited the disease. We included siblings and cousins in this study. The baseline tool to study other family subjects was based on the phenotypic characterisations of each child. RESULTS: . Two children with the severe type of ISH showed craniosynostosis (brachycephaly and scaphocephaly) associated with multiple contractures, progressive joint osteolysis ending up with multiple joint dislocations. The full exome sequencing was carried out, revealing a previously reported heterozygous nonsense mutation с.1294С>Т and a novel heterozygous non-synonymous substitution c. 58T>A in ANTRX2 gene. Three children (sibling and cousins) manifested variable clinical manifestations relevant to ISH. Specifically, asymptoamtic skin and skeletal abnormalities of hypoplastic clavicles and 'shepherd's crook' deformity and coxa vara. CONCLUSION: It is mandatory to perform extensive family pedigree search to detect asymptomatic clinical features in siblings and cousins in families with first degree related marriages. Interestingly, in the mild and the moderate types of ISH, we observed undescribed combination of asymptomatic skin and skeletal abnormalities. This is a comparative study between the severe and the mild/moderate types in a group of children from consanguineous families. Our current study extends the phenotypic characterisations of ISH.

Unusual presentations, management and outcomes of gastric stromal tumors: a single-center case series.

BACKGROUND: Gastrointestinal stromal tumors (GISTs) are uncommon mesenchymal tumors of the gastrointestinal tract. This study explores the safety of laparoscopy and the long-term oncological outcome in gastroesophageal GIST treatment. METHODS: A prospectively maintained single-institution database was examined. The variables collected were patient demographics and comorbidities, surgical access (laparoscopic/open), type of surgery, length of stay, and complications. RESULTS: A total of 69 patients underwent GIST resection between January 2011 and June 2018, of whom 56.5% were male; the median age was 68 years (interquartile range 60-76). The majority of patients (78.3%, n=54/69) had a laparoscopic resection. Median length of stay was 6 days in the laparoscopic group and 9 days in the open group (P=0.003). Most patients had wedge excision (n=57/69, 82.6%), while 12 patients (17.4%) required a gastrectomy (one a Merendino type). All patients had an R0 resection and 1 patient (1.4%) had a recurrence, despite having a low-risk grade original tumor with negative margins. Patients in the open group had a significantly higher proportion of patients with a high-risk tumor (50%) compared to the laparoscopic group (3.7%, P=0.001). The mean survival was 92.7 months (95% confidence interval 86.3-99.2). Survival was better in the laparoscopic group (100.4 months) compared with the open group (55.1 months, P<0.001). CONCLUSION: Laparoscopic gastric GIST resection is an oncologically safe alternative to open surgery and is associated with a shorter hospital stay with no difference in complication rates or recurrence rates.
