Intracardiac surgery in infants under age 3 months: Incremental risk factors for hospital mortality

During the 13 year period from January 1967 to July 1980, the hospital mortality rate for open intracardiac operations in infants in the first 3 months of life was 43 percent (75 deaths among 194 patients), higher than the 22 percent mortality rate (35 deaths in 161 patients) for closed operations in the same age group. The mortality rate was lower late in the experience (p = 0.0001). Poor preoperative condition of the patient increased the mortality rate 87 percent in patients preoperatively acidotic or in shock [preoperative class V]and 22 percent in patients with moderate or severe symptoms but without recent hemodynamic deterioration (preoperative class II or III). The presence of major associated cardiac lesions increased hospital mortality (p < 0.0001). The hospital mortality rate was highest (59 per cent) in infants less than age 1 month, possibly in part because of their sensitivity to the damaging effects of cardiopulmonary bypass. This hypothesis is supported by the association of a long period of cardiopulmonary bypass with increased hospital mortality (p = 0.05) and of total circulatory arrest during profound hypothermia with decreased mortality (p = 0.05). Most deaths (72 percent) occurred in association with acute postoperative cardiac failure. The length of cardiac ischemia (aortic cross-clamping time) was directly related to the probability of cardiac death, unless cold cardioplegia was used. Thirteen percent of the hospital deaths were associated with acute postoperative respiratory failure. Current mortality rates in typical cases without acute hemodynamic deterioration is estimated from these data to be 7 percent (70 percent confidence limits 4 to 12 percent), as a result of the scientific advances made over this period of time. Research into mechanisms of the damaging effects of cardiopulmonary bypass should further improve results in these very young patients.     

A new ilarvirus isolated from Viola × wittrockiana and its detection in pansy germoplasm by qRT-PCR

An infectious agent was transmitted mechanically from samples of Viola spp. showing white mosaic and leaf deformation to Nicotiana benthamiana. dsRNA extracted from the N. benthamiana plants migrated as four specific bands that were absent in non-inoculated plants. Sequence analysis of cDNA clones generated from the second-smallest dsRNA showed the greatest similarity to the RNA3 of prune dwarf virus (PDV) (genus Ilarvirus, family Bromoviridae). However, because of differences in molecular, biological, and serological properties between this virus isolate and PDV, a new ilarvirus species, named “Viola white distortion associated virus” (VWDaV) is proposed. Specific oligonucleotides and a TaqMan^® probe were designed for diagnostic purposes. The possible association between the virus and the original white distortion symptoms is discussed.     

A nutraceutical extract from Inula viscosa leaves: UHPLC-HR-MS/MS based polyphenol profile,and antioxidant and cytotoxic activities

Nowadays, advanced extraction techniques and highly sensitive metabolic profiling methods are effectively employed to get new information on plant chemical constituents. Among them wild medicinal plants or their parts, with large and ancient use in folk medicine, are investigated for their potential functional use and cultivation. In this context, Inula viscosa leaves engaged our attention. A simple experimental design, based on Soxhlet extraction and chromatographic fractionation, allowed us to obtain the investigated polyphenol fraction (IvE). UHPLC-HRMS analyses revealed shikimoyl depsides of caffeic acid and unusual dihydrobenzofuran lignans as main secondary metabolites. These compounds, together with cinchonain-type phenols, and hydroxycinnamoyl flavonol glycosides, are reported for the first time in inula. Overall, forty-three secondary metabolites were identified. The extract exerted a remarkable antiradical activity towards DPPH^• and ABTS^+•. Furthermore, it was able to inhibit cell viability and mitochondrial redox activity of neuroblastoma, hepatoblastoma and colon carcinoma cells, whereas it did not affect cell density of HaCaT cells immortalized human keratinocytes. As detected by the oxidant-sensing probe 2′,7′-dichlorodihydrofluorescein diacetate, the inhibitory responses seemed to be related to IvE-induced increase of intracellular reactive oxygen species (ROS). The obtained results highlighted that inula leaves, nowadays even undervalued and unexplored, could be considered a renewable source of nutraceutical compounds.     

Yersinia enterocolitica causing suppurative arthritis of the shoulder.

Yersinia enterocolitica is a rare cause of extra-intestinal disease. A case in a 60 year old butcher with hepatic cirrhosis who developed suppurative arthritis of the shoulder caused by Y enterocolitica is presented. There was no evidence of gastrointestinal infection or septicaemia. The severity of the illness was associated with various factors, including the underlying disease, the type of occupation, and the difficulties encountered in defining the optimal therapeutic regimen.     

A Solution to the High-Riding Nipple–Areola Complex

There are limited techniques described in the literature on how to lower the nipple–areola complex following surgery to the breast. We present a case of successful correction of a high-riding nipple using a Z-plasty technique with an 8-year follow-up in a breast reconstruction patient. The technique described may also be applicable to cases of high-riding nipples following aesthetic breast surgery such as reduction mammaplasty.     

The salivary microbiota as a diagnostic indicator of oral cancer: A descriptive,non-randomized study of cancer-free and oral squamous cell carcinoma subjects

Background  

The purpose of the present investigation was to determine if the salivary counts of 40 common oral bacteria in subjects with an oral squamous cell carcinoma (OSCC) lesion would differ from those found in cancer-free (OSCC-free) controls.     

Use of the Griffiths Mental Development Scales in an agro‐industrial province in the Philippines

Background There is a need to assess neurobehavioral performance of children in developing countries using standardized developmental tools. Methods The Griffiths Mental Development Scales was evaluated in the Philippines by comparing the performance of 742 Filipino children longitudinally at 6, 12 and 24 months old to those of their British counterparts. Results The mean general and subquotient scores of Filipino children were all within average for age. Comparison with British children showed that except for performance subscales, Filipino children had significantly higher developmental subquotients at 6 months old. As the Filipino infants grew older, their developmental subquotients in all subscales were significantly lower, except for personal and social skills at 24 months old. The genetic predisposition as evidenced by modest maternal scores on the Wechsler Intelligence Scales and lack of familiarity with test materials are factors that may influence the developmental patterns of Filipino children. Conclusion Although the performance of the Filipino children in the Griffiths test were within average with age, their performance on developmental subquotients at later ages of 12 and 24 months were significantly lower than British children and may have been influenced by differences in ethnicity, cultural traditions and limited environmental resources.

Synergy between the genes for butyrylcholinesterase K variant and apolipoprotein E4 in late-onset confirmed Alzheimer's disease

The allelic frequency of the gene for the K variant of butyrylcholinesterase (BCHE-K) was 0.17 in 74 subjects with late-onset (age > 65 years) histopathologically diagnosed Alzheimer's disease (AD), which was higher than the frequencies in 104 elderly control subjects (0.09), in 14 early-onset cases of confirmed AD (0.07) and in 29 confirmed cases of other dementia (0.10). The association of BCHE-K with late-onset AD was limited to carriers of the epsilon 4 allele of the apolipoprotein E gene (APOE), among whom the presence of BCHE-K gave an odds ratio of confirmed late-onset AD of 6.9 (95% C.I. 1.65-29) in subjects > 65 years and of 12.8 (1.9-86) in subjects > 75 years. In APOE epsilon 4 carriers over 75 years, only 1/22 controls, compared with 10/24 confirmed late-onset AD cases, had BCHE-K. We suggest that BCHE-K, or a nearby gene on chromosome 3, acts in synergy with APOE epsilon 4 as a susceptibility gene for late-onset AD.
