Argumentation is an important aspect in the field of education because of its impact on learning processes. At the same time, argumentation is a complex activity in terms of cognitive, relational, emotional and social dynamics. In this paper, I investigate and I describe possible difficulties encountered by children during the argumentative process. The study involves 25 preschool children at a kindergarten engaged in three building tasks. The tasks were video-recorded and the argumentative discussions transcribed. For the aim of this paper, I analyze how argumentation are distributed among participants. I select interactions in which participants apparently do not argue or there are differences in the degree of argumentative participation between participants of the same group. I analyze these interactions and moments of impasse in the argumentative steps. The findings show how the simplicity of solving the task (e.g., when children do not encounter any problem in completing the activity) and the children’s self-perception of their competences in solving the task may have an impact on argumentation activities. Moreover, this perception is co-constructed by children within the interaction. The study contributes to the line of research on designing argumentation and highlights the role of the adult in managing children’s interactions.

AbstractLearning is a complex phenomenon. Contemporary theories of education underline active participation of learners in their learning processes. One of the key arguments supporting this approach is the learner’s simultaneous and unconscious development of their ability of “learning to learn”. This ability belongs to the soft skills highly valued by employers today.For Mathematics Education, it means that teachers have to go beyond making calculations and memorizing formulas. We have to teach the subject in its social context. When the students start understanding the relationship between real-life problems and the role of numbers and formulas for their solutions, their learning becomes a part of their tacit knowledge. Below we explain the theoretical background of our approach and provide examples of such activities.

Objective: To analyze safety and efficacy of single-dose ketorolac after primary palatoplasty (PP). Design: Consecutive cohort of patients undergoing PP, comparing to historical controls. Setting: A large academic children’s hospital. Patients, Participants: A consecutive cohort of 111 patients undergoing PP (study n = 47) compared to historical controls (n = 64). Interventions: All patients received intraoperative acetaminophen, dexmedetomidine, and opioids while the study group received an additional single dose of ketorolac (0.5 mg/kg) at the conclusion of PP. Main Outcome Measures: Safety of ketorolac was measured by significant bleeding complications and need for supplementary oxygen. Efficacy was assessed through bleeding, Face Legs Activity Cry Consolability (FLACC) scale, and opioid dose. Results: Length of stay was similar for both groups (control group 38.5 hours [95% CI: 3.6-43.3] versus study group 37.6 hours [95% CI: 31.3-44.0], P = .84). There were no significant differences in all postoperative FLACC scales. The mean dose of opioid rescue medication measured as morphine milligram equivalents did not differ between groups ( P = .56). Significant postoperative hemorrhage was not observed. Conclusions: This is the first prospective study to evaluate the safety and efficacy of single-dose ketorolac after PP. Although lack of standardization between study and historical control groups may have precluded observation of an analgesic benefit, analysis demonstrated a single dose of ketorolac after PP is safe. Further investigations with more patients and different postoperative regimens may clarify the role of ketorolac in improving pain after PP.

Abstract Objectives The aim of this study was to investigate the role of CD68 (+) histiocytic macrophages (H-M) in the nasal polyp pathogenesis. Materials and Methods The study group consisted of 24 adult patients with nasal polyposis. The control group consisted of 11 adult patients without nasal polyps. A total of 36 nasal polyp samples (10-nasal cavity, 10-maxillary sinus, and 16-ethmoid sinus) from the study group and 11 inferior turbinate samples from the control group were analyzed by immunohistochemical staining, with monoclonal antibodies against CD68 (+) H-M. Results CD68 positivity was significantly higher than the control group in the subepithelial (SE) layer of the ethmoid sinus, and deep layers of nasal cavity, maxillary, and ethmoid sinuses. In SE and deep layers of ethmoid and maxillary sinuses, CD68 positivity was significantly higher than that of the epithelial layer. In the deep layer, histiocytic macrophages tended to gather around eosinophils. Conclusion The high numbers of CD68 (+) histiocytic macrophages mainly located in deep layer of lamina propria may be responsible for the phagocytosis of eosinophils within the polyp tissue. Therefore, it may be concluded that increased macrophages in nasal polyps do not trigger the growth of nasal polyps. Instead, they may serve to reduce the number of eosinophils in already-developed nasal polyps.

Abstract Background The intersphincteric plane (ISP) is a potential space between the external and the internal anal sphincters. About 90% of the perianal sepsis is caused by an obstruction of the ducts of anal glands with subsequent secondary bacterial infection. The imaging modalities used to diagnose perianal sepsis are the ultrasound via endoanal and transperineal routes and magnetic resonance imaging. Objective  The study aimed to identify the various patterns of the ISP sepsis and their incidence among our study group and to clarify the significance of ISP in the pathogenesis of anorectal abscesses and various types of perianal fistula tracts, to optimize the surgical management. Methods Retrospective descriptive study in which 57 patients with an ISP sepsis were evaluated with full medical history, clinical exam, and ultrasound; the final diagnosis was based on combining the results of ultrasound, digital rectal examination under anesthesia, and the operative results. Results The current study showed many patterns of the ISP sepsis and estimated the incidence of each pattern among our study group; such patterns could be fistula tracts, sinus tracts, abscesses, intersphincteric abscess with supralevator extension, sinus with abscess formation, fistula with abscess formation, distension of the ISP with free pus, and other complex patterns like horse abscess, abscess with transsphincteric sinus, and ISP fistula/sinus with transsphincteric branches. Conclusion Understanding the role of the ISP in the pathogenesis of anorectal abscesses and perianal fistula tracts can help in reaching the optimum way of management.

The article offers a critique of the concept of cultural intelligence (CQ) from a semiotic perspective. It addresses three assumptions that underpin the CQ concept: that CQ exists, that conflict and misunderstandings are antithetical to CQ and that metacognition involves a cultural dimension. The analysis focuses in particular on the dimension of cultural metacognition which has recently been claimed to be the CQ concept’s main contribution compared to earlier concepts such as cross-cultural or intercultural competence, a claim which is found to be overstated. The article uses the example of CQ training to illustrate the need for greater attention to context and motivation when CQ is deployed for business purposes, as well as to the role of experience in cultural learning processes. At a broader level, the article urges caution in assuming that all human attributes can be trained for business purposes, especially through short-term interventions.

In Reply.— We appreciate the interest in our report published in Pediatrics (1986;77:212-216). The three letters raise similar questions, and in response we would like to make three points. First, including the two infants in the control group who died with the infants in the study group still resulted in significant differences between the two groups regarding duration of furosemide (Lasix) therapy, hypochloremia, or metabolic alkalosis (P > .001). Second (as noted in our discussion), bronchopulmonary dysplasia is a complex disease process.

Abstract Many serious and fatal infections with urogenital mycoplasmas in immunocompromised patients have been reported. M. genitalium is recognized as a cause of male urethritis and other common genitourinary diseases. The aim of the study was to estimate prevalence of urogenital mycoplasmas which can cause complications in men with common genitourinary diseases. Study included 85 men with genitourinary tract carcinoma (n = 35), urolithiasis (n = 36), and BPH (benign prostatic hyperplasia) (n = 14). The control group consisted of 50 healthy men. FVU (first void urine) samples were examined by PCR for the presence of urogenital mycoplasmas DNA. Occurrence of urogenital mycoplasmas was significantly more common in study group compared with control 24/85 (28.2%) and 7/50 (14%), respectively (p = 0.05). In men with urolithiasis, positive results for mycoplasmas DNA were significantly more frequent than in control: 33.3% vs. 14% (p < 0.05). In patients with urolithiasis DNA of U. urealyticum was most often found, while in the genitourinary carcinoma and BPH groups, U. parvum was more frequent. Incidence of M. fermentans was also significantly higher in the urolithiasis group vs. control (p = 0.03). A higher percentage of positive results for urogenital mycoplasma DNA in study group has been found. Further studies are required to confirm the role of urogenital mycoplasmas in the development of infectious complications among patients with urolithiasis, genitourinary carcinoma, and BPH.
