Hemoperitoneum caused by a ruptured GIST located in the posterior gastric wall managed by endoscopic diagnosis and laparoscopic treatment: case report and literature review

A case of hemoperitoneum caused by a ruptured gastrointestinal stromal tumor (GIST) of the posterior gastric wall is presented. An otherwise healthy 81-year-old man presented with abdominal pain/tenderness and anemia (hemoglobin: 7.4 g/dL). Computed tomography scan showed hemoperitoneum and a gastric mass of uncertain nature. As the patient was hemodynamically stable, a mini-invasive approach was decided. Esophagogastroscopy revealed an umbilicated mass of the posterior gastric wall, therefore allowing for a correct preoperative diagnosis of GIST and its appropriate treatment by laparoscopic atypical gastrectomy. Laparoscopically, a longitudinal resection of gastric fundus including the tumor was performed in a sleeve gastrectomy fashion, 25 minutes after the induction of pneumoperitoneum. The outcome was uneventful. Pathologic examination confirmed a benign 4 × 3-cm gastric GIST with <1 mitosis per 50 high power field, staining positive for CD117 (C-KIT) and negative for S-100 protein and smooth muscle actin. To our knowledge, it is the first case of a successful laparoscopic resection of an endoscopically diagnosed gastric GIST in an emergency setting. Hemoperitoneum is a rare, potentially severe complication of GIST. As bleeding is rarely severe, most patients may benefit from a mini-invasive approach, even if the tumor is located in the posterior gastric wall.     

Association between anemia and physical disability in older patients: role of comorbidity

BACKGROUND AND AIMS: In older persons, anemia is a common medical disorder and is often associated with comorbidity and poor health outcomes. We evaluated the relationship between anemia and physical disability in a sample of older hospitalized patients, taking into account the role of comorbidity. METHODS: Cross-sectional analysis of the baseline data of the Italian Group of Pharmacoepidemiology in the Elderly Study. Patients aged 65 years or older (n=10,903), admitted to participating centers in the 1993-1998 survey period, were included. Anemia was defined according to the World Health Organization (WHO) criteria; physical disability was defined as need for assistance in performing at least one Activity of Daily Living (ADL) in the week before admission. Comorbidity was ascertained using the Charlson Index. RESULTS: Prevalence of anemia was 41.1%. In the unadjusted analysis, anemia was associated with increased likelihood of disability, in both women (Odds Ratio [OR]: 1.54; 95% Confidence Interval [CI]: 1.38-1.71) and men (OR 1.70; CI 1.52-1.90). After inclusion of demographics and life-style factors in multivariate analysis, the strength of association was only modestly attenuated, whereas nutritional factors and disease-related variables resulted in a greater reduction of the strength of association. In analyses stratified by comorbidity severity, the association between anemia and disability was statistically significant only in patients with the lowest comorbidity levels (p for anemia Charlson Index interaction term <0.05, in both women and men). CONCLUSIONS: Among hospitalized subjects, anemia is associated with ADL disability. The disablement process associated with anemia may be partially explained by nutritional and disease-related factors. However, anemia appears to have an independent effect, particularly in subjects with low comorbidity.     

Reduced lung function in healthy preterm infants in the first months of life

RATIONALE: Preterm delivery has been associated with a higher incidence of respiratory morbidity even in infants that do not have significant respiratory disease during the neonatal period. Reduced flows have been reported in children and adolescents born prematurely. OBJECTIVE: The aim of this study was to assess lung function in healthy preterm infants in the first months of life. METHODS: Preterm infants with less than 48 h of supplemental oxygen were recruited. Lung function was assessed by the raised-volume rapid thoracic compression in the first months of life. The control group consisted of full-term infants without a history of respiratory diseases. MEASUREMENTS AND MAIN RESULTS: Sixty-two preterm (29 male) and 27 full-term (10 male) infants were tested. Adjusting for length, age, and sex, we found a mean significant reduction of 92 ml/s (22%) in FEF(50), 73 ml/s (21%) in FEF(25-75), and 19 ml (28%) in FEV(0.5) in the preterm group. These differences in expiratory flows remained significant using another model that adjusts for lung volume (p < 0.01 for FEF(50), FEF(25-75), and FEV(0.5), and p < 0.05 for FEF(75)). In the preterm group, after adjusting for length, male sex, lower gestational age, and increased weight were significantly and independently associated with reduced flows. CONCLUSIONS: Our findings confirm that prematurity is independently associated with reduced lung function and that this is detectable in the first months of life. Male sex, lower gestational age, and weight are important predictors for reduced expiratory flows in this group.     

Genotype–phenotype relationship in three cases with overlapping 19p13.12 microdeletions

We describe the detailed clinical and molecular characterization of three patients (aged 7, 8^4/12 and 31 years) with overlapping microdeletions in 19p13.12, extending to 19p13.13 in two cases. The patients share the following clinical features with a recently reported 10-year-old girl with a 19p13.12 microdeletion: mental retardation (MR), psychomotor and language delay, hearing impairment, brachycephaly, anteverted nares and ear malformations. All patients share a 359-kb deleted region in 19p13.12 harboring six genes (LPHN1, DDX39, CD97, PKN1, PTGER1 and GIPC1), several of which may be MR candidates because of their function and expression pattern. LPHN1 and PKN1 are the most appealing; LPHN1 for its interaction with Shank family proteins, and PKN1 because it is involved in a variety of functions in neurons, including cytoskeletal organization. Haploinsufficiency of GIPC1 may contribute to hearing impairment for its interaction with myosin VI. A behavioral phenotype was observed in all three patients; it was characterized by overactive disorder associated with MR and stereotyped movements (ICD10) in one patient and hyperactivity in the other two. As Ptger1-null mice show behavioral inhibition and impulsive aggression with defective social interaction, PTGER1 haploinsufficiency may be responsible for the behavioral traits observed in these patients.     

Vascular complications with newer generations of angioseal vascular closure devices

OBJECTIVES: To evaluate the safety and efficacy of newer generations of a single vascular closure device (VCD), Angioseal, compared to contemporaneous manual compression. BACKGROUND: Previous assessment of VCD safety and efficacy has been based primarily on outcomes associated with the original VCD. Few data exist comparing safety and efficacy of modifications of the original VCDs. METHODS: We evaluated in-hospital outcomes of patients undergoing diagnostic cath and percutaneous coronary intervention at a single center: 3,898 with manual compression and 3,898 with the Angioseal VCD. Three generations of the Angioseal device were studied: Generation 1, 7/97-4/00; Generation 2, 5/00-6/02; and Generation 3, 7/02-12/03. Propensity analysis was used to match patients within each generation for clinical and procedural covariates. RESULTS: Closure success was 98.5% for Generation 1, 98.6% for Generation 2, and 98.1% for Generation 3, P = NS. The odds ratio for any vascular complication comparing Angioseal to manual compression was 0.92 (0.42-2.01) for Generation 1; 0.83 (0.49-1.41) for Generation 2; and 0.75 (0.32-1.77) for Generation 3. Multivariate logistic regression identified closure success and Angioseal device Generation 3 versus Generation 1 as predictive of reduced vascular complications during the entire study period. CONCLUSION: These data indicate that the newest generation of the Angioseal VCD is at least as effective as the original device. Moreover, use of the Angioseal VCD was associated with vascular complications similar to or lower than vascular complications following manual compression for each generation of Angioseal device analyzed.     

Sclerodermatous chronic graft-versus-host disease after allogeneic hematopoietic stem cell transplantation: incidence, predictors and outcome

Scleroderma may be one of the most severe forms of chronic graft-versus-host disease (GVHD). We retrospectively evaluated its incidence, predictor variables and outcome in 133 patients who survived at least 4 months after allogeneic hematopoietic stem cell transplantation. The 5-year cumulative incidence was 15.5% in patients with chronic GVHD. The generalized form had a progressive course despite immunosuppressive therapy. Eosinophilia, autoimmune markers, and previous skin involvement by chronic GVHD with disorders of pigmentation were significantly associated with an increased probability of developing scleroderma.
