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.

To date, there has been no reliable test to identify unfavorable course of Chronic Rhinosinusitis with Nasal Polyps (CRSwNP), especially in aspirin intolerant patients. The research aimed to analyze the expression of transcript variants of PTGS1 and PTGS2 genes in the pathobiology of the disease. The study was performed on 409 adult patients: 206 CRSwNP patients including 44 (21.36%) aspirin intolerant patients and 203 healthy volunteers in the control group. Transcript variants of the PTGS1 and PTGS2 genes named as follows: COX1.1 for NM_000962, COX1.2 for NM_080591, COX1.3 for NM_001271165.1, COX1.4 for NM_001271368.1, COX1.5 for NM_001271166.1, COX2.1 for NM_000963.3, COX2.2 for AY_151286 and COX2.3 for BQ_722004 were confirmed using direct sequencing and quantified using targeted qPCR. The coexistence of all examined transcript variants in the study and the control group and significant differences between both were found. In aspirin sensitive patients, the levels of COX1.2, COX1.3, COX1.4 and COX1.5 isoforms were higher compared to aspirin-tolerant patients. The severity of symptoms was bigger in patients with higher expressions of variants: COX1.1 (R with dCt = −0.134; p = 0.0490), COX1.3 (R = −0.1429; p = 0.0400) and COX1.5 (Rs = −0.1499; p = 0.032). The expression of COX1.1 (Rs = −0.098; p = 0.049) and COX1.5 (Rs = −0.141; p = 0.043) isoforms increased with polyposis advancement in endoscopy. With the CT extent of sinuses opacification, COX1.1 isoform also significantly increased (Rs = −0.163; p = 0.020). The isoforms COX1.3, COX1.4, COX1.5 and COX2.1 may promote milder CRSwNP course. On the contrary, the variants COX1.1, COX1.2 and COX2.2 may be involved in a more aggressive disease.

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.

AbstractObjective:This study compared the results of nasal Staphylococcus aureus carriage and nasal cytology in men with and without a moustache.Methods:The study group comprised 118 adult men with a moustache, and the control group consisted of 123 adult men without a moustache. Samples were taken from the participants' right nasal cavity for cytology and from the left nasal cavity for microbiology.Results:The results for S aureus were positive in 19.5 per cent (n = 23) of participants with a moustache and in 20.3 per cent (n = 25) of men without a moustache. This difference was not significant (p > 0.05). However, nasal cytology revealed rich eosinophil clusters in participants with a moustache.Conclusion:The presence or absence of a moustache had no effect on nasal S aureus colonisation. However, further research is needed to understand whether the presence of a moustache increases the risk of allergic or non-allergic rhinitis.

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.

Abstract Septic cardiomyopathy remains a difficult medical problem to manage in critically ill patients. With all currently available therapeutic options, the mortality rate in these patients remains high. Our study included 29 patients diagnosed clinically with sepsis. A control group was used to compare the results. In all patients, p53 expression was assessed in cardiac tissue obtained from these patients and a statistical correlation was made with clinical data. The different expression rates of p53 do not correlate with patient’s age, having appropriate means in years, but with an increasing tendency with increasing expression (p=0.2110). The pulmonary infections are responsible for the majority of the septic state in the study group (over 55%). The difference between the infection sites is statistically significant (p<0.0001).

Objectives. The aim of the study was to evaluate the activity of cathepsin B, collagenases, trypsin, and plasmin and concentration of cystatin C in serum of healthy pregnant women in peripartum period.Study Design. The study group included 45 women in uncomplicated pregnancies. Blood samples were collected in four time points. Enzyme activity was measured by spectrofluorometric method. The level of cystatin C was measured using immunonephelometric method.Results. Mean activity of cathepsin B and the level of serum cystatin C were significantly higher in the study group. Collagenase activity was significantly lower in the study group than the control group. No differences in collagenase, plasmin, and trypsin activity on each day of the peripartum period were found.Conclusion. High activity of cathepsin B and increased level of cystatin C are typical for women in late pregnancy. Those levels significantly decrease after delivery which can be associated with potential role of those markers in placental separation. The insignificant changes of cystatin C level in the peripartum period seem to exclude the possibility of using cystatin C as a marker for renal insufficiency in the peripartum period but additional research is necessary to investigate the matter further.

Abstract Objectives The aim of the study was to evaluate the coconut oil pulling efficacy as adjuvant in reducing plaque formation and in treating plaque-induced gingivitis. Materials and Methods A sample of 20 patients was divided into two groups: a study and a control group. In the study group, coconut oil, in form of mouthwash, was administered to a sample of patients affected by gingivitis, aged between 18 and 35. The protocol established a daily application of the product for 30 days, where clinical parameters for plaque formation and gingivitis—plaque index (PI), bleeding index (BI)—will be evaluated during the recalls on a specific periodontal chart. The control group did not associate a coadjuvant to the normal daily oral health procedures and the same clinical parameters were evaluated at t0 and after 30 days (t1). The data were statistically analyzed using Student’s t-test, establishing the significance level as p < 0.05. Results PI and BI decreased in both groups, with a more relevant and significant drop in the study group, from a mean value of PI of 58.0 to 19.3 and a mean value of BI of 33.5 to 5.0. In the control group, the values decreased, respectively, from 53.9 to 29.1 for PI, and from 33.5 to 16.2. Furthermore, no significant side effect was reported during coconut oil pulling therapy. Conclusions The collected data showed significant and promising improvements in reducing plaque formation and gingivitis. However, further researches have to be performed to have more consistent and statistically significant data on larger samples and to fully understand the mechanisms of action and effectiveness.
