ABSTRACT Objective: To compare arch perimeter and teeth size, number, and shape between the two sides of the dental arch—the canine displacement side (DS) and the nondisplacement side (NDS)—in subjects with unilateral palatally displaced canine (PDC). Materials and Methods: Orthopantomograms (OPTs) of 240 subjects with unilateral PDC and 240 OPT matching controls were used. Additionally, study casts of 100 study subjects and 100 controls were used. The age of subjects ranged between 14 and 25 years. Dental casts were digitized and several parameters were recorded. Results: The transverse width from midpalatal line to the buccal segment and the palatal area on the DS was larger than that in the NDS (P < .05 to .001), with no difference in tooth size between both sides. Maxillary second premolars, canines, and lateral incisors in the PDC group were smaller than those in control group. Peg-shaped lateral incisors were significantly more frequent in the study group (P < .001). Conclusions: The transverse width of the DS was larger than that of the NDS. Both sides were generally smaller than those of the control group. Tooth size in the DS was comparable to that in the NDS but smaller than those of the control group. A missing or peg-shaped lateral incisor was the most common reported anomaly.

Abstract Background The SARS-CoV-2 coronavirus disease (COVID-19) has had a major impact on health care services globally. Recent studies report that emergency departments have experienced a significant decline in the number of admitted patients in the early phase of the pandemic. To date, research regarding the influence of COVID-19 on emergency medical services (EMS) is limited. The present study investigates a change in the number and characteristics of EMS missions in the early phase of the pandemic. Methods All EMS missions in the Northern Ostrobothnia region, Finland (population 295 500) between 1 March to 30 June 2020 were screened and analyzed as the study group. A control group was composed from the EMS calls between the corresponding months in the years 2016–2019. Results A total of 74 576 EMS missions were screened for the study. Within the first two months after the first COVID-19 cases in the study area, the decline in the number of EMS missions was 5.7% – 13% compared to the control group average. EMS time intervals (emergency call to dispatch, dispatch, en-route, on-scene and hospital handover) prolonged in the COVID-19 period. Dispatches concerning mental health problems increased most in the study period (+1.2%, p &lt; 0.001). Only eleven confirmed COVID-19 infections were encountered by EMS in the study period. Conclusion Our findings suggest that the present COVID-19 pandemic and social restrictions lead to changes in the EMS usage. These preliminary findings emphasize the importance of developing new strategies and protocols in response to the oncoming pandemic waves.

Childbirth Preparation

Background: This study examined the effectiveness of a birth preparation course on coping with childbirth among primigravid ultra-orthodox Jewish women in Israel. Methods: In total, 130 ultra-orthodox 25–35-week primigravid women were divided into a study (n = 100, participated in birth preparation courses) and a control (n = 30, did not participate in the courses) group. A questionnaire was delivered three times: T1—before the course/delivery, T2—two–three days after delivery, and T3—a month after delivery. Results: At T3, self-efficacy among the study group was higher than in the control group. Differences in self-efficacy were found over time regardless of the group (F(2,246) = 12.83, p < 0.001), as a time–group interaction effect (F(2,246) = 10.20, p < 0.01). Self-efficacy in the study group (Mean, M = 3.40, Standard deviation, SD = 0.63 at T1) dropped to M = 3.06, SD = 0.76 at T2 and rose to M = 3.34, SD = 0.64 at T3. In the control group, self-efficacy (M = 3.53, SD = 0.56 at T1) dropped to M = 3.26, SD = 0.63 at T2 and to M = 2.95, SD = 0.76 at T3. Discussion: The childbirth preparation course was found to be effective in raising self-efficacy among primigravid ultra-orthodox religious women when compared to the control group.

AbstractIntroduction:Laryngopharyngeal reflux is increasingly being implicated in several otolaryngological disorders.Aims:To study a potential correlation between pre-operative laryngopharyngeal reflux and wound healing and recovery after tonsillectomy, based on subjective and objective findings.Materials and methods:A prospective, blinded study was undertaken, including 60 patients scheduled for tonsillectomy, divided into two equal groups: a study group (group A) with pre-operative laryngopharyngeal reflux documented using ambulatory 24-hour pH monitoring; and a control group (group B) without laryngopharyngeal reflux.Results:Group A had significantly higher pain scores on the seventh and 14th post-operative days (p = 0.022 and p = 0.000, respectively) and took a significantly longer time to return to normal eating (p = 0.013), compared with group B. Group A also showed significantly slower healing on the seventh and 14th post-operative days, as estimated by assessing the grade of post-operative slough formation (p = 0.016 and p = 0.029, respectively). A significant correlation between the number of pharyngeal reflux episodes and the degree of post-operative slough was also found.Conclusions:Laryngopharyngeal reflux can significantly decrease wound healing following tonsillectomy. Therefore, pre-operative recognition and management of this condition is desirable in order to eliminate its negative post-operative effect.

This research monograph is based on dental casts for 184 white children residing in Massachusetts and Delaware. The topics discussed pertain to tooth size, dental arch size, and positional interrelationships of the teeth in the two arches. On each subject, the investigator had available a series of dental casts "covering the transition from the primary to the secondary dentition" (p. 40). The casts were amassed in part at the Center for Research in Child Health and Development, Boston (Dr. Harold C. Stuart), and in part at a public school in Wilmington, Delaware (Dr. Richard H. Stucklen).

Abstract Purpose The goal was to study the effects of early cervical headgear treatment on maxillary and mandibular dental arch area, shape and interarch dimensions. Methods The total study group comprised 67 children aged 7.6 years (standard deviation 0.3) with Angle class II malocclusion collected between 1992 and 1996. The children were randomly divided into two groups of equal size. In the first group, cervical headgear treatment was started immediately and undertaken for 2 years. The remaining patients served as untreated controls. Dental casts were taken and scanned at the beginning of treatment (T0) and at the 2‑year (T1) and 4‑year follow-up (T2). Three-dimensional landmarks describing the positions of maxillary and mandibular incisors, canines, first and second premolars and first molars were used to calculate and visualize the maxillary and mandibular dental arch area and shape using the polynomial equation y = Ax6 + Bx2. Results Significant changes in the shape and area of both maxillary and mandibular dental arches were induced with cervical headgear. The headgear increased dental arch area, sagittal dimensions at the mid-sagittal line and transversal dimensions at all of the measured levels in both dental arches compared to the control group. Conclusions Cervical headgear is an effective treatment device to gain space in both dental arches. Furthermore, when used as an early phase treatment, relapse is relatively small compared to the gained space.

Objective: to evaluate kidney function in patients with spinal degenerative-dystrophic diseases (SDDDs) who take nonsteroidal anti-inflammatory drugs (NSAIDs) as repeated short cycles of treatment for severe back pain.Patients and methods. The investigation enrolled 97 patients with SDDDs who took NSAIDs for back pain (a study group). A control group consisted of sexand age-matched healthy individuals who had not used NSAIDs within the past year (n=40). Glomerular filtration rate (GFR) was estimated using the CKD-EPI equation and markers of kidney injury (albuminuria and globulinuria) were measured.Results. In the study group, GFR was decreased to <90 ml/min/1.73 m2 in 61 (62.9%) patients, to <60 ml/min/1.73 m2 in 11 (11.3%); the mean GFR was 77.5 [68.0; 89.0] ml/min/1.73 m2; in the control group, a decline in GFR to 89–60 ml/min/1.73 m2 was recorded in 35 (62.5%) cases; this indicator was >90 ml/min/1.73 m2 in the remaining 15 (37.5%) cases; the mean GFR was 82.5 [70.8; 90.0] ml/min/1.73 m2 (p≥0.05 for all pairwise comparisons). A decrease in GFR to <60 ml/min/1.73 m2 was found in 11 (11.3%) patients in the study group and in nobody in the control group (p=0.026). Elevated albuminuria was noted in 74 (76.3%) patients with SDDDs and in 9 (22.5%) healthy individuals (p<0.05). Albumin/creatinine ratio was 57.1 [33.8; 82.4] mg/g in the study group and 25.0 [17.5; 32.9] mg/g in the control group (p<0.0001). Increased globulinuria was established in all the patients with SDDDs and only in 3 (7.5%) healthy examinees. Globulin/creatinine ratio was 134.7 [77.5; 197.7] mg/g in the study group and 12.9 [0.5; 18.1] mg/g in the control group (p<0.0001).Conclusion. A decline in GFR to <60 ml/min/1.73 m2 was more often seen in the patients taking NSAIDs for spine pain caused by SDDDs than in the healthy individuals. In case of comparable GFR, the level of kidney injury markers was significantly higher in the study group than that in the control group, which suggests that patients with SDDDs who take NSAIDs have subclinical tubulointerstitial and glomerular changes.

Introduction. Closing the wound cavity after the coccyx resection in patients with posttraumatic coccygodynia remains an issue unresolved. Closing the wound cavity with local tissues often leads to the wound dehiscence due to excessive tension which in turn leads to suppuration and prolonged healing.This paper aims to assess experimentally the effectiveness of using ground autograft bone of the coccyx removed for the closure of the surgical wound.Materials and methods. In the animal experiment the coccyx resection was performed under a combined anaesthesia in six pigs (three in the study group and three in control). In the control group the wound edges were sutured to its floor. In the study group after the coccyx resection the ground bone mass made of the coccyx resected was implanted into the wound cavity.Results and discussion. In the control group the wound dehiscence was registered in all the animals. After the animals were taken out of the experiment it was established that in the study group a new consolidated bony conglomerate was formed without any pronounced inflammatory changes around the wound. In control the wound cavity healed with secondary intention.Conclusions. The study confirms the effectiveness of using ground autograft bone for the closure of the wound cavity.

Objective: To establish the diagnostic utility of the platelet-lymphocyte ratio in pregnant women with preeclampsia. Methods: A case-control study was carried out at the Hospital Central “Dr. Urquinaona” Maracaibo, Venezuela. A total of 180 pregnant women were selected. Ninety preeclamptic women were included as the study group (group A) and a control group selected for their age and body mass index similar to the study group, which consisted of 90 healthy normotensive pregnant women (group B). The general characteristics, platelet-lymphocyte ratio values and diagnostic efficacy were determined. Results: Group A patients presented lower platelet and lymphocyte values compared to group B patients (p <0.001). However, no statistically significant differences were found in platelet-lymphocyte ratio between group A patients (115.2 ± 32.7) and group B patients (122.3 ± 23.8; p = 0, 0971). A cut-off value of the platelets-lymphocyte ratio of 117 presented a value below the curve of 0.57, the sensitivity of 47.8%, the specificity of 50.0%, the positive predictive value of 48.9%, and the negative predictive value of 52.2%, with a diagnostic accuracy of 48.9%. Conclusion: Platelet-lymphocyte ratio is not a useful tool in the diagnosis of preeclampsia, since patients with the syndrome present similar values to normotensive pregnant women.
