Abstract Purpose:Severe head traumas in the childhood age group has an important place in terms of mortality and morbidity among all traumas. Our aim in this study is to consider the relationship between the severity of severe head trauma and arterial blood gas (ABG) parameter levels in children.Methods:In our study, patients with head trauma, intubation and Glascow Coma Score (GCS) ≤ 8 were retrospectively analyzed. Showing homogeneous distribution; Independent sample T test was used for pH, PCO2 and base extract (BE) parameters, and Mann Whitney U test was used for PO2 and lactate parameters not showing homogeneous distribution. ROC analysis was done.Results:Of the 48 patients included in the study, 17 died while lying in the intensive care unit. There was no statistical difference when looking at the relationship between age, gender, surgical methods and mortality of the patients (p> 0.05). The relationship of patients with acidosis, hypercapnia and hyperlactatemia in ABG with mortality was statistically significant (p˂0.05). No statistically significant difference was found between surviving and deceased in ABG of patients regarding BE and hypoxia (p= 0.075; 0.175). there was a statistically significant difference between the mean values of PCO2 and lactate which are among the quantitative values and those who survived and died (p <0.05).Conclusion: Acidosis, the presence hypercapnia and hyperlactatemia were found to be associated with mortality in children with severe head trauma in ABG analysis. This study shows that PCO2 and lactate levels in ABG can be a biomarker in determining the prognosis in pediatric patients with traumatic brain injury (TBI).

The Relationship

To investigate the relationship of MUC1, MUC5AC, and the syndrome of spleen and stomach, 109 subjects (34 peptic ulcer (PU), 62 chronic gastritis (CG), and 13 healthy volunteers (CON)) were included. All the subjects included were surveyed with questionnaire to classify them into damp-heat syndrome of spleen and stomach (DHSS), spleen-qi deficiency syndrome (SQD), and CON, examined by gastric endoscope, and biopsied. Rapid urease and methylene blue staining (MBS) were performed on every subject to diagnose for Helicobacter pylori (Hp) infection, and both were defined as Hp-positive. Hematoxylin and eosin (HE) staining was performed on every specimen to explore the histomorphology, inflammatory degree, and inflammatory activity of different groups; then Elivision™ plus kit was used to test the expression of MUC1 and MUC5AC. All the results of digital images were reviewed by two experts blindly. The inflammatory degree with Hp infection was higher than those uninfected or CON, but no significant difference was found between DHSS and SQD. And the expressions of MUC5AC with positive Hp was higher than those with negative Hp or CON regardless of the deficiency and solid syndrome of spleen-stomach but not for MUC1. We speculate that the deficiency and solid syndrome of spleen-stomach is a condition like Tai Ji symbol of dynamic equilibrium, showing the higher expression of MUC5AC but no change of MUC1 in the circumstance of Hp infection.

Supratentorial Mass

✓ Intracranial pressures above and below the tentorium, arterial blood pressure, heart rate, and respiratory rate were recorded continuously before, during, and after expansion of a supratentorial mass in awake unsedated cats. In general, as the mass enlarged, the intracranial pressure rose; however, considerable variation was observed among animals with respect to specific mass size and associated intracranial pressures. There was considerable variation in the relationship of supratentorial pressure to infratentorial pressure. No animal survived that had sustained a mass-induced pressure exceeding 1100 mm H2O, and survival was shorter with greater pressures. Systemic hypertension occurred always and only when the infratentorial pressure exceeded 600 mm H2O, regardless of the magnitude of the associated supratentorial intracranial pressure. The methodological limitations of previous studies of mass-induced intracranial hypertension appear to have been substantially reduced by the technique described.

Objective. Abusive head trauma is the most common cause of morbidity and mortality in physically abused infants. Effective prevention requires the identification of potential perpetrators. No study has specifically addressed the relationship of the perpetrators of abusive head trauma ("shaken baby syndrome") to their victims. The objectives of this study were to identify the abusers and their relationship to victims in these cases. Methods. We reviewed the medical charts of 151 infants who suffered abusive head trauma to determine the perpetrator of the abuse. Caretakers were classified by level of certainty: confession to the crime, legal actions taken, or strong suspicion by the staff. The relationship of abusers to victims was analyzed. Results. Male victims accounted for 60.3% of the cases. Twenty-three percent of the children died, although death rates for boys and girls did not vary significantly. Male perpetrators outnumbered females 2.2:1, with fathers, step-fathers, and mothers' boyfriends committing over 60% of the crimes. Fathers accounted for 37% of the abusers, followed by boyfriends at 20.5%. Female baby-sitters, at 17.3%, were a large, previously unrecognized group of perpetrators. Mothers were responsible for only 12.6% of our cases. All but one of the confessed abusers were with the child at the time of onset of symptoms. Conclusions. Our data suggest male caretakers are at greater risk to abuse infants. Baby-sitters are a concerning risk group, because they represent a significant proportion of abusers, and they more easily escape prosecution. In addition, no prevention efforts have been directed at baby-sitters. These statistics could help change the focus of efforts to prevent abusive head trauma.

The Relationship

Veno-arterial differences of pyruvate and lactate across the myocardium in chloralose-anesthetized dogs were very variable; in any one animal they changed continually with time despite constant blood flow and arterial blood concentrations. There was a systematic tendency of v-a lactate to vary with v-a pyruvate, as expressed in the calculated "Δ excess lactate," which remained nearly constant (or, if blood flow changed, bore a constant ratio to (a-v)O2). No change in Δ excess lactate from control values occurred in nonhypoxic experiments despite marked changes in v-a differences, arterial blood composition, and coronary flow. Cardiac Δ excess lactate became positive in most animals breathing 10% O2 in N2; output of excess lactate was also observed in all those in which moderate muscular exercise was induced. This anaerobic metabolism, or change in the relationship between pyruvate and lactate exchanges, was interpreted as an indication that O2 delivery response was not adequate to meet cardiac tissue requirements during such mild stresses when judged by the standards of adequacy of the basal state.

The use of blood gas analysis is to determine the Acid-base status required to treat patients with emergency conditionssuch as metabolic disorders and respiratory diseases. Benchtop device is commonly used in hospitals to analyze blood gas;however, handheld devices are recently more often used in emergency settings due to its quick and simple process. Thisstudy was performed to compare blood gas analysis results between the i-STAT handheld device and the Nova pHox Ultrabenchtop device that were currently being used in the central laboratory. This cross-sectional study was conducted by using42 arterial blood patients that were measured with i-STAT handheld device dan Nova pHox Ultra benchtop device. The pH,pCO2, and pO2 parameters were then evaluated. The data were analyzed using Spearman's correlation test, Mann-Whitneytest, and Bland-Altman plots. This study showed a very strong positive correlation for all parameters. Mann-Whitneycomparison test showed that there was no significant difference between the result of the two devices (p-value > 0.05). Allparameters showed that 95% of plots were within the acceptable limit. There was no clinical significance on the mean biasesof blood gas results between both devices. The i-STAT and Nova pHox Ultra devices showed a good agreement for bloodgas measurement. Therefore, both devices can be used interchangeably with minimal effect on clinical decision-making.

ABSTRACT Objective: To determine the relationship of the surgeon handedness and operative site laterality on operative duration and hearing improvement in otologic surgery, and to further explore whether this relationship may be related to surgeon experience. Methods:Design: Retrospective CohortSetting: Tertiary Private Teaching HospitalParticipants: Seventy-three (73) patients aged 18 to 65 years old who underwent primary ear surgery under general anesthesia between January 2016 and December 2019 were retrospectively divided into two groups: 39 contralateral and 34 ipsilateral. The operative durations and hearing improvements were compared using independent t-tests, with consideration of surgeon experience in years further stratifying patients. Results: There was no significant difference in operative duration, t(71) = 1.14, p = .26, between the contralateral (M = 281.95 minutes, SD = 71.82) and ipsilateral (M = 261.15, SD = 79.26) groups. This same pattern was more pronounced among surgeons with 10+ years of experience although there was also no significant difference in operative time, t(33) = 1.31, p = .19 for both ipsilateral and contralateral surgeries There was no statistically significant difference, t(36) = -0.72, p = .47, in overall mean hearing gain among patients in the contralateral (M = +2.22 dB, SD = 10.54) and ipsilateral (M = +5.12 dB, SD = 14.26) groups. Although the difference was also not statistically significant, t(16) = -1.94, p = .07 for contralateral (M = 0.00, SD = 5.43) and ipsilateral (M = +7.95 dB, SD = 11.52) procedures performed by surgeons with experience of 10 years or more, a mean hearing gain of +7 dB in the ipsilateral group compared to 0 dB in the contralateral group was notable. Conclusion: This study did not prove that regardless of surgeon experience, right-handed surgeons operating on the right ear and left-handed surgeons operating on the left ear have better ear surgery outcomes of operative duration and hearing improvement compared to right- handed surgeons operating on the left ear and left-handed surgeons operating on the right ear. Future studies on larger samples with more complete data may yet demonstrate this effect.
