We compared the performance of the BD Max enteric parasite panel to routine microscopy and an in-house PCR for the detection of Giardia intestinalis, Entamoeba histolytica, and Cryptosporidium spp. The enteric parasite panel showed good specificity for all targets and good sensitivity for E. histolytica and Cryptosporidium spp. Sensitivity for G. intestinalis with the BD Max enteric parasite panel was equivalent to that with microscopy.

Aim: To investigate the prevalence, co-morbidities and aetiologies of severe mental retardation (SMR) in a cohort of Swedish children and to further penetrate aetiologies in the group with undetermined causes by application of updated clinical-genetic methods. Methods: The study was population-based and included children living in the County of Halland in western Sweden in 2004 (born 1987-1998; 46 000 children). Patients were identified through habilitation centres, paediatric clinics and school health services. Patients with unclear prenatal aetiology were investigated with single nucleotide polymorphism (SNP)-array. Results: Severe mental retardation was identified in 133 children from 132 families, corresponding to a prevalence of 2.9 per 1000 children. There were more males than females (90:43).The aetiology was prenatal in 82 (62%), perinatal in 14 (10%) and postnatal in 8 (6%). In 29 (22 %) children, mainly males with autism, the cause could not be related to the time of birth. In the prenatal group, genetic causes dominated, but still 23 children remained undiagnosed; in 5/19 of these patients, a diagnosis could be made after SNP-array analysis. One or more associated neurological handicaps were found in more than half of the children. Conclusion: Prevalence and co-morbidity were similar to previous Scandinavian studies. High-resolution chromosomal micro-array techniques are valuable diagnostic tools, reducing the number of patients with unexplained SMR. © 2011 The Author(s)/Acta Pædiatrica © 2011 Foundation Acta Pædiatrica.

Background and aims. Proteins induced by vitamin K absence for factor II (PIVKA-II) is an enzyme-linked immunosorbent assay that monitors uncarboxylated prothrombin and responds to vitamin K deficits prior to changes in the prothrombin test. The aim of this project was to study perioperative PIVKA-II changes during various types of surgery in a prospective observational study. Methods. Patients undergoing abdominal or orthopaedic surgery were included. Blood was sampled on the day of surgery (preoperatively) and up to 5 days after surgery. The activated partial thromboplastin time, Quick and Owren prothrombin times were analyzed, together with PIVKA-II. Results. Thirty-nine patients were included, 27 +male and 12 +female. All but 7 +patients had elevated PIVKA-II levels preoperatively. PIVKA-II levels had already increased significantly (p < 0.017) on day 1 after surgery as compared to presurgery plasma levels. The median PIVKA-II was highest on day 5. Routine tests were mostly normal. No significant difference in PIVKA-II was seen when comparing patients undergoing abdominal versus orthopaedic surgeries. There was no significant correlation between PIVKA-II and routine coagulation tests. Patients with anterior resection, emergency laparotomy and emergency hip fractures had higher postoperative increases, which could be linked to increased gastrointestinal recovery times, paralytic ileus, peritonitis and comorbidities. Conclusions. PIVKA-II levels increase during the perioperative period, despite mostly normal routine coagulation tests. Pre- and perioperative vitamin K supplementation in patients with elevated PIVKA-II levels should be studied, and its clinical significance be defined in future studies. © 2015 Informa Healthcare.

Objective: Treatment with levothyroxine in primary hypothyroid patients does not always provide complete regression of associated symptoms despite normalised TSH levels. Several sources report ratios of triiodothyronine (T3) to thyroxine (T4) are diminished in hypothyroid patients following a daily levothyroxine regimen. It is known that thyroid-stimulating hormone (TSH) increases de-iodination of T4 to T3. We hypothesise that a raise in TSH levels caused by a temporary withdrawal of oral levothyroxine will be followed by an increased conversion of T4 to T3. Methods: Thirteen patients treated with monotherapy of levothyroxine were included in our pilot study. Treatment was temporarily discontinued for one week in which TSH, free T3 (fT3) and free T4 (fT4) were monitored. TSH and fT3 to fT4 ratios were compared with baseline values. Results: Statistically significant elevations in TSH and fT3 plasma levels relative to fT4 were demonstrated in all patients after withdrawal of levothyroxine. Conclusion: Both TSH and fT3 to fT4 ratios rose following temporary discontinuation of levothyroxine. The effect on symptoms and quality of life is not evaluated in this pilot study. Our results warrant further investigation into whether or not longer dosing intervals would demonstrate commensurate hormone elevations that better reflects the hormonal ratios in healthy subjects and if this also has an effect on quality of life scores. © Touch medical media 2013.
