Survival from coma induced by an intentional 36-g overdose of extended-release quetiapine.

Quetiapine is a second-generation antipsychotic drug approved for the treatment of bipolar disorders and schizophrenia. Acute quetiapine overdose is rare, and quetiapine has long been thought to be safer than other antipsychotics. Nevertheless, as reported in the literature, the severity of the effect of quetiapine overdose has not been associated with a high serum concentration of the drug or with the reported ingested dose. In this article, we report a case of survival from coma induced by a massive extended-release (XR) quetiapine ingestion at a dose greater than reported in some previous fatal cases. A 34-year-old woman with chronic schizophrenia ingested 36 g of quetiapine fumarate XR for attempted suicide. She was initially lethargic, but her clinical conditions rapidly deteriorated and she collapsed unconscious. The woman was taken to the nearest hospital, where the medical emergency team found her in deep coma with response only to deep painful stimuli (Glasgow Coma Scale 9). An endotracheal tube was inserted for airway protection, and the patient was transferred to a critical care area for ventilatory support and maintenance of hydration status and electrolytic balance. Spontaneous breathing was restored in approximately 36 hours, and a few days later, she was discharged without reporting clinical complications. This is the first case of coma induced by an intentional 36-g overdose of quetiapine XR. Given the widespread use of quetiapine and the lack of information about its toxicity in overdose, this case report reinforces the importance of closely monitoring patients taking quetiapine and helps to better define the safety of this drug.

Amoxicillin-induced hemolytic anemia in a child with glucose 6-phosphate isomerase deficiency.

OBJECTIVE: To describe the first case of amoxicillin-induced nonimmune hemolytic anemia in a child with glucose-6-phosphate isomerase (GPI) deficiency. CASE SUMMARY: A 3-year-old boy with GPI deficiency was admitted for upper respiratory tract infection and fever. The patient was treated with a standard dose of amoxicillin (50 mg/kg/day). On hospital admission, the child had a chronic moderately low hemoglobin level (8.6 g/dL), but within 24 hours of the first amoxicillin dose, the hemoglobin level markedly decreased (5.8 g/dL), the reticulocyte level increased (58%), and the urine darkened. Results of the direct and indirect Coomb's tests were negative and the acute hemolytic phase ended spontaneously 8 days after amoxicillin withdrawal (hemoglobin 9.5 g/dL, reticulocytes 22%). DISCUSSION: All previous cases of amoxicillin-induced hemolytic anemia have been attributed to an immune mechanism. Given the absence of anti-reticulocyte antibodies (Coomb's test), we suggest that the amoxicillin-induced hemolytic anemia in our patient occurred via a nonimmune mechanism favored by the child's GPI deficiency. Based on a MEDLINE search, we believe this to be the first report of amoxicillin-induced nonimmune hemolytic anemia in a child with GPI deficiency. GPI deficiency has been associated with well-compensated chronic hemolytic anemia that can become clinically relevant consequent to the administration of drugs. GPI deficiency can lead to impairment of the system that removes free radicals generated by amoxicillin, thereby resulting in oxidation of hemoglobin and destabilization of red cell membranes, with acute hemolysis and severe hemoglobinuria. The Naranjo probability score was consistent with a probable relationship between the hemolytic anemia and amoxicillin therapy. CONCLUSIONS: This report reinforces the hypothesis that a drug-sensitivity reaction is closely related to a genetically transmitted enzyme deficiency.

Pancreaticoduodenectomy as the primary therapeutic choice in cystic dystrophy of the duodenal wall in heterotopic pancreas.

On the basis of a review of the literature and description of a clinical case, the aim of this paper was to evaluate the role of pancreaticoduodenectomy as the primary therapeutic choice in a rare, serious condition such as cystic dystrophy of the duodenal wall in heterotopic pancreas. The diagnosis is difficult because of the non-specific clinical manifestations, and radiological and endoscopic imaging are decisive. Computed tomography and magnetic resonance are very useful for demonstrating the presence of cysts in a thickened duodenal wall but endoscopic ultrasonography is the most useful imaging examination. The choice of therapeutic option is still debated. Although some Authors have proposed a medical approach using octreotide or endoscopic treatment for selected patients, pancreaticoduodenectomy is usually proposed for symptomatic patients. When surgery is needed, pancreaticoduodenectomy should be preferred, reserving by-pass procedures for high-risk patients. Because of the non-specific clinical manifestations and the very difficult diagnostic and therapeutic management, these patients need to be studied and treated in specialised, dedicated centres.

Negative pressure therapy alone or with irrigation in the management of severe peritonitis.

BACKGROUND: Ogilvie was the first to publish on open abdomen (OA) for the treatment of the damages caused by penetrating abdominal wounds in war events. Research improved those devices that allow a controlled, homogeneous and continuous extraction of contaminated fluids from all abdominal recesses, which are nowadays the base of the "Open Abdomen" technique. MATERIALS AND METHODS: From August 2012 to February 2016 at the Department of Emergency Surgery of Cardarelli Hospital in Naples, 40 patients affected by Severe Peritonitis have been treated with OA technique. 13 (32,5%) were treated with only the suction-drainage system, 27 patients (67,5%) were treated with suction drainage and irrigation system. Abthera® device was used in all patients. RESULTS: The duration of treatment was 15 days in the first group, with 7 device's substitutions, while in the second group it was about 10 days with 4 substitutions At the end of the procedure we were able to perform primary fascia closure in 7 cases (53,8%) in the first group and in 23 cases (85.2%) in the second group. 4 patients (30,8%) died in the first group, and 7 (26%) in the second. CONCLUSION: The suction/irrigation method seems to be appropriate to use in case of a surgical emergency that causes severe peritonitis. It is associated not only with lower death rates but also with better parameters, that are more frequently worse during prolonged treatments. Irrigation of abdominal cavity causes also less retraction of fascia recti which leads to a higher rate of direct fascia closure. Key Words: Emergency surgery, Irrigation, Open abdomen, Peritonitis.

BioEnterics Intragastric Balloon (BIB) versus Spatz Adjustable Balloon System (ABS): Our experience in the elderly.

The BioEnterics Intragastric Balloon (BIB) and the Spatz Adjustable Balloon System (ABS) are in fact recommended for weight reduction as a bridge to bariatric surgery. We retrospected studied patients with body mass index (BMI) and age ranges of 37-46 and 70-80 years, respectively, who had undergone BIB from January 2010 to July 2012 and prospected studied patients who had undergone Spatz balloon from July 2012 to August 2014. The aim of this study is to compare BIB and Spatz in terms of weight loss, complications, and maintenance of weight after removal. For both procedures, the median weight loss was 20 ± 3 kg, median BMI at the end of the therapy was 32 ± 2, and no severe complication occurred.

Automodification of PARP and fatty acid-based membrane lipidome as a promising integrated biomarker panel in molecular medicine.

AIM: Establishing by statistical analyses whether the analyses of auto-modified poly(ADP-ribose)polymerase and erythrocyte membrane fatty acid composition (Fat Profile(®)), separately or in tandem, help monitoring the physio-pathology of the cell, and correlate with diseases, if present. PATIENTS & METHODS: Ninety five subjects were interviewed and analyzed blindly. Blood lymphocytes and erythrocytes were prepared to assay poly(ADP-ribose)polymerase automodification and fatty acid based membrane lipidome, respectively. RESULTS: Poly(ADP-ribose)polymerase automodification levels confirmed their correlation with DNA damage extent, and allowed monitoring disease activity, upon surgical/therapeutic treatment. Membrane lipidome profiles showed lipid unbalance mainly linked to inflammatory states. Statistically both tests were separately significant, and correlated each other within some pathologies. CONCLUSION: In the laboratory routine, both tests, separately or in tandem, might be a preliminary and helpful step to investigate the occurrence of a given disease. Their combination represents a promising integrated panel for sensible, noninvasive and routine health monitoring.

Endoscopic diagnosis and treatment of neuroendocrine tumors of the digestive system.

The authors evaluated the role of endoscopic techniques in the diagnosis and in the potential treatment of neuroendocrine tumors (NET) localized in the gastro-entero-pancreatic system, on the basis of their experience and of the international literature. NET are rare tumors that arise from neuroendocrine cells of the gastrointestinal tract and pancreas. It is a possibility that both the digestive endoscopy and EUS play an important role in the diagnosis, staging and surveillance of this disease. In some cases, especially in the early stages, surgical endoscopy allows the treatment of such tumors.

Relationship between gastroesophageal reflux disease and Ph nose and salivary: proposal of a simple method outpatient in patients adults.

INTRODUCTION: The frequency of gastroesophageal reflux disease (GERD) is increasing, in part through easy inspection of the upper digestive tract, but especially for a real spread of the disease as a consequence of modernity, lifestyle, incorrect dietary rules, and stress arising from social norms. It is a common chronic gastrointestinal disorder in Europe and the United States. MATERIALS AND METHODS: The aim of our study is to highlight a relationship between gastroesophageal reflux disease and salivary pH as evidenced by indicator strips, especially in the outpatient field. Twenty adult subjects (10 males and 10 females) aged between 18 and 50 years (GROUP A)_ were selected. How to control a homogeneous group of 20 patients without GERD, or from any type of allergies (GROUP B) was enlisted. RESULTS: This method has provided excellent results showing no difference in the measured values compared with the traditional instrumental measurement. CONCLUSION: Our study has allowed us to observe a strong correlation between the saliva pH, nasal cavities and the interaction between the two districts, and could be the basis for a diagnosis of GERD especially in primary health care clinics and in the initial stage of the disease.

Morbid Obesity: treatment with Bioenterics Intragastric Balloon (BIB), psychological and nursing care: our experience.

Obesity is considered a chronic disease, difficult to treat, and is the first cause of death in the world that is predictable. The surgical approach is limited to patients with severe obesity but there is an intermediate group who are not candidates for immediate surgery. The BioEnterics Intragastric Balloon (BIB) is recommended for weight reduction as a bridge to bariatric surgery. All patients in the study underwent a psychological evaluation prior to placement of the BIB.

Staple-line leak after sleve gastrectomy in obese patients: A hot topic in bariatric surgery.

Laparoscopic sleeve gastrectomy is a surgical procedure that is being increasingly performed on obese patients. Among its complications, leaks are the most serious and life threatening. The placement of esophageal, covered, self-expandable metal stents in these cases has been performed by many authors but reports on the outcome of this procedure are limited and the technical aspects are not well defined. Stent migration is the main complication of the procedure and poses a challenge to the surgeon, with a limited number of options. Here we evaluate the technical and clinical outcome of a new, dedicated, self-expanding metal stent, comparing the advantages of this stent to those traditionally used to treat staple-line leak after sleeve gastrectomy. While published data are limited, they seem support the use of this kind of new stent as the best option for the stenting treatment of a staple-line leak after sleeve gastrectomy, over other kinds of stents. Further studies based on larger series are needed to better evaluate patient outcome.

Quality of bowel cleansing in hospitalized patients undergoing colonoscopy: A multicentre prospective regional study.

BACKGROUND: Quality of bowel cleansing in hospitalized patients undergoing colonoscopy is often unsatisfactory. No study has investigated the inpatient or outpatient setting as cause of inadequate cleansing. AIMS: To assess degree of bowel cleansing in inpatients and outpatients and to identify possible predictors of poor bowel preparation in the two populations. METHODS: Prospective multicentre study on consecutive colonoscopies in 25 regional endoscopy units. Univariate and multivariate analysis with odds ratio estimation were performed. RESULTS: Data from 3276 colonoscopies were analyzed (2178 outpatients, 1098 inpatients). Incomplete colonoscopy due to inadequate cleansing was recorded in 369 patients (11.2%). There was no significant difference in bowel cleansing rates between in- and outpatients in both colonic segments. In the overall population, independent predictors of inadequate cleansing both at the level of right and left colon were: male gender (odds ratio, 1.20 [1.02-1.43] and 1.27 [1.05-1.53]), diabetes mellitus (odds ratio, 2.35 [1.68-3.29] and 2.12 [1.47-3.05]), chronic constipation (odds ratio, 1.60 [1.30-1.97] and 1.55 [1.23-1.94]), incomplete purge intake (odds ratio, 2.36 [1.90-2.94] and 2.11 [1.68-2.65]) and a runway time >12h (odds ratio, 3.36 [2.40-4.72] and 2.53 [1.74-3.67]). CONCLUSIONS: We found no difference in the rate of inadequate bowel preparation between hospitalized patients and outpatients.

Guanfacine for attention deficit and hyperactivity disorder in pediatrics: a systematic review and meta-analysis.

To review the evidence from randomized controlled trials (RCTs) on the safety and efficacy of guanfacine in pediatric attention deficit hyperactivity disorder (ADHD), a bibliographic search up to May 2014 was performed using the Cochrane Library׳s Central Register of Controlled Trials, the Embase, PsycINFO, and Medline databases, and clinical trials registers. The search terms used were: ["guanfacine"] and ["child" or "adolescent" or "pediatrics"] and ["randomized controlled trial"] and ["Attention Deficit Disorder with Hyperactivity" or "Attention Deficit Disorder" or "Attention Hyperactivity Disorder" or "Hyperactivity" or "ADHD"]. A meta-analysis was performed using response, defined as a score ≤ 2 on the Clinical Global Impression Improvement score, as the outcome measure. In all, 7 out of 48 studies were included, for a total of 1752 participants. All studies compared guanfacine versus placebo, with a duration ranging from 6 to 16 weeks. In all, the Clinical Global Impression Improvement score was reported as a secondary measure. Overall, 694/1177 (59.0%) participants in the guanfacine group benefited from the treatment compared to 192/575 (33.3%) in the placebo group (pooled OR 3.2; 95%CI 2.4-4.1). The participants with at least one adverse event were 948 (82.4%) in the guanfacine and 376 (67.9%) in the placebo group (OR 2.6; 95%CI 1.6-4.4). Somnolence (OR 4.9), sedation (OR 2.8), and fatigue (OR 2.2), were the adverse events with the greatest risk of occurrence in the guanfacine versus the placebo group. On the basis of seven randomized, placebo controlled trials guanfacine resulted safe and effective in treating children and adolescents with ADHD.

Evaluation of cosmetic product exposures reported to the Milan Poison Control Centre, Italy from 2005 to 2010.

INTRODUCTION: To the average consumer, "cosmetics" are not considered to cause damage to human health under normal conditions of use. Thus, cosmetic "safety" does not require any particular attention to the possibility that cosmetics may result in a toxic exposure, especially for children. Poison Control Centres (PCCs) provide specialized and rapid information for consumers and health professionals to ensure management of events related to the exposures to different agents, including Cosmetics. Poison Control Centres also represent a unique source of information to investigate the frequency and type of exposures to cosmetic and the related risks. OBJECTIVE: An analysis of cases concerning human exposures to cosmetics collected from 2005 to 2010 by the PCC at the Ospedale Niguarda Ca' Granda (Milan, Italy) was performed. RESULTS: During this period, 11 322 human exposure cases related to cosmetics were collected accounting for 4.5% of the total human clinical cases. Almost, all the requests for assistance came from consumers (53%) and hospitals (40%). The most frequently reported site of exposure was the consumer's own residence (94%). The exposures mainly involved children younger than 4 years (77%). No difference in gender distribution was observed (female 49%, male 51%). Almost, all of the exposures were unintentional (94%). Intentional exposures, mainly related to suicide attempts and accounted for 6% of cases involving persons aged more than 12 years. Personal hygiene products (30%), perfumes and hair care products (excluding hair dyes) (both 13%) were the most frequently involved categories. Symptoms were present only in 26% of the exposures and were mostly gastrointestinal (46%). Most of the cases were managed at home (43%) whereas hospital intervention was required in 38%. CONCLUSION: Since the exposure frequency seems more likely to reflect product availability and accessibility to ingestors, our results call for closer attention to this type of hazard, especially for children younger than 4 years of age.

Safety of attention-deficit/hyperactivity disorder medications in children: an intensive pharmacosurveillance monitoring study.

OBJECTIVE: Our intensive pharmacosurveillance monitoring program was performed to increase the number of adverse drug reactions (ADRs) recorded in the Italian spontaneous reporting database, and to systematically collect more thorough data about atomoxetine (ATX) and methylphenidate (MPH) safety in the pediatric setting. METHODS: From September 2007 to October 2010, 1841 youth were enrolled in the Italian Attention- Deficit/Hyperactivity Disorder Register, but we report here on the 76 children from the five Reference Prescription Centers in Campania, an Italian region where we administered our systematic adverse event checklist. RESULTS: Among our cohort, 68 children received a prescription of ATX and 8 received a prescription of MPH. Most children were male and between 10 and 13 years of age, had a diagnosis of attention-deficit/hyperactivity disorder-combined (ADHD-C) and had learning disability as the main comorbidity. Most ADRs reported to the Italian spontaneous reporting database occurred in patients from Campania. Twenty-five experienced at least 1 ADR for a total of 40 ADRs reported to the Italian drug agency. Most ADRs were common and not serious, and resolved completely. Weight loss was the most frequently reported ADR. Only two ADRs were unexpected and only one was uncommon. Sixteen ADRs resulted in permanent drug withdrawal. Based on the Naranjo algorithm, 25 ADRs were considered "probable" and 15 were considered "possible." CONCLUSIONS: Although our data provide reassurance of the safety of ATX and MPH, several unexpected or uncommon ADRs (hepatomegaly, suicidal ideation, weight gain, or drug interactions) were identified by our intensive pharmacosurveillance monitoring program. Our results show that an intensive pharmacosurveillance monitoring program that involves pharmacovigilance centers and clinicians can improve the collection of information on drug safety in children.
