Snoring is a loud sound that can be produced when air across the relaxed tissues of the throat. The causes of snoring include age, being overweight or out of shape, the way you are built, nasal and sinus problems, sleep posture, alcohol, smoking and medications. The present study was performed to find the association between the habit of snoring and health problems like hypertension, breathlessness, fatigue and chest pain among genders. A self-developed questionnaire to assess the snoring habits of the participants with their underlying health problems. The study was conducted on an online platform and the responses were collected. The datas were collected and analysed with the help of statistical software SPSS version 22 and chi-square test was used as a statistical analysis to find how snoring habit affects the participants based on the gender. The results revealed that male respondents who have the habit of snoring are more related to problems like breathlessness, hypertension, fatigue and chest pain compared to females. This result can be justified by the fact that females have strong hormonal support offered by estrogen that protects them from cardiovascular and respiratory disorders.

Although extensively studied, psoriasis still has negative consequences and is associated with multiple comorbidities, including metabolic syndrome. The severity of psoriasis seems to influence the occurrence of diagnostic criteria for metabolic syndrome. 208 patients diagnosed with psoriasis were identified, who were divided into lots depending on the severity of psoriasis, but also to the presence or absence of metabolic syndrome. Interpretation of statistical data was done with SPSS V21 (Statistical Package for Social Science) and MEDCALC (Statistical Software). The coexistence of severe psoriasis with metabolic syndrome increases the risk of developing cardiovascular diseases by 2.97 or greater, with a confidence interval of [1.60, 5.51], than that of patients with severe psoriasis who have no metabolic syndrome. The hypothesis was statistically confirmed by p = 0.003. Analyzing the total group with psoriasis by severity, we found the following distribution: from the total number of 208 patients, 39 (18.8%) had severe psoriasis, 83 (39.9%) moderate psoriasis and 86 (41.3%) mild psoriasis. The higher incidence of metabolic syndrome in patients with psoriasis is evidenced by the Pearson Chi-Square test, where p [0.001. The association of metabolic syndrome in patients with psoriasis is evident. The more severe the psoriasis, the more likely it is to develop metabolic syndrome.

Positive occipital sharp transients of sleep (POSTS) and lambda waves have similar morphology and location. We studied a possible association between these 2 normal EEG patterns. We reviewed a series of consecutive unselected ambulatory EEGs during a 3-month period (October 16, 2017 to January 19, 2018) and identified records with POSTS and records with lambda waves. Statistical analysis was performed using a chi-square test. A total of 140 ambulatory EEGs were reviewed. Duration of EEGs ranged from 24 to 168 hours (mean 76 hours). The population was 34% males, with ages ranging from 3 to 93 years (mean 48 years). Of the 140 records, 30 were abnormal, including 20 with epileptiform abnormalities. A chi-square test for independence (with Yates continuity correction) indicated a significant association between POSTS and lambda waves, χ2(1, n = 140) = 69.208, p < .001, φ = 0.72. In addition, 100% of records with lambda waves had POSTS, and 72% of records with POSTS had lambda waves. There is a high association between lambda waves and POSTS. This suggests a strong similarity between the 2 waveforms, and possibly a common occipital generator.

Objective: To determine the prevalence and distribution of premature eruption and agenesis of premolars in a sample of Turkish children. Study design: A sample of 1715 patients aged 5 to 11 years was selected. Panoramic radiographs were used to assess premature eruption and agenesis of premolars. Developmental stage of erupted premolars was assessed using Demirjian’s method and selecting prematurely erupted premolars on the basis of clinical eruption with a root length less than half of their final expected root lengths. Statistical analysis was performed using chi-square test (p &lt;.05). Results: One hundred fifteen (6.7%) of 1715 patients presented at least one premolar agenesis with no significant sex difference (56 boys, 59 girls). Mandibular second premolars were the most absent teeth. Multiple agenesis of premolars (3.4%) was more common than single agenesis (3.3%). A total of 85 (5.0%) patients (51 boys, 34 girls; no significant sex difference) had at least one prematurely erupted premolar, and maxillary first premolars were most commonly affected. Early erupted premolars were in stage D or E based on Demirjian’s dental formation scale. Conclusions: The prevalence of premature eruption and agenesis of premolars in Turkish children were 5.0% and 6.7%, respectively. Both conditions are not uncommon and may highlight the need for early diagnosis to prevent subsequent clinical problems.

Seasonality Of Births

SummarySeasonal variation in the births of patients with schizophrenia is a consistently replicated epidemiological finding. Few studies have investigated this phenomenon among patients with a diagnosis of affective disorder. The majority of season of birth studies have employed the chi square test for statistical analysis, a method that has been subject to some criticism. Using a Kolgomorov-Smirnov type statistic, the quarterly birth distribution of 6,646 patients with an ICD 9/10 diagnosis of affective disorder were compared to the general population. Only the births of those individuals with unipolar forms of affective disorder (n = 4,393) differed significantly from the general population, with significant excesses and deficits in the second quarter and fourth quarter respectively. These results were not altered by application of the displacement test. © 1998 Elsevier, Paris

Objective: To determine the number and pattern of palatal rugae in Nepalese subjects and to find the association of gender with the number and pattern of palatal rugae. Materials & Method: 200 Nepalese subjects comprising of 100 male and 100 female were randomly selected and their maxillary casts were examined for the palatal rugae length applying the classification proposed by Thomas and Kotze and palatal rugae pattern was recorded using the classification given by Kapali. Statistical analysis using Student t-test was applied for comparing the number of palatal rugae between right and left sides. Chi square test was used to find the association between gender and number of rugae as well as the pattern. Result: The study demonstrated that the mean number of primary palatal rugae on left side was predominant, similarly wavy pattern was the most predominant in Nepalese subjects. No statistical significant difference was noticed in the palatal rugae number and pattern between the gender groups. Conclusion: The study found predominant palatal form in Nepalese subjects which might have superior effectiveness in population differentiation and may be used as an effective tool in forensic odontology identification.

Objectives. To assess the incidence of testicular appendices (Tas), epididymal anomalies (EAs), and processus vaginalis (PV) patency in patients with undescended testis (UT) according to testicular position and to compare them with human fetuses. Methods. We studied 85 patients (108 testes) with cryptorchidism and compared the features with those of 15 fetuses (30 testes) with scrotal testes. We analyzed the relationships among the testis and epididymis, patency of PV, and the presence of TAs. We used the Chi-square test for statistical analysis (p<0.05). Results. In 108 UT, 72 (66.66%) had PV patent, 67 (62.03%) had TAs, and 39 (36.12%) had EAs. Of the 108 UT, 14 were abdominal (12.96%; 14 had PV patency, 9 TAs, and 7 EAs); 81 were inguinal (75%; 52 had PV patency, 45 TAs, and 31 EAs), and 13 were suprascrotal (12.03%; 6 had PV patency, 13 TAs, and 1 EAs). The patency of PV was more frequently associated with EAs (p=0.00364). The EAs had a higher prevalence in UT compared with fetuses (p=0.0005). Conclusions. Undescended testis has a higher risk of anatomical anomalies and the testes situated in abdomen and inguinal canal have a higher risk of presenting patency of PV and EAs.

Aim: It was aimed to reveal the perspectives and satisfaction levels of 4th and 5th grade-clinical students who go on practice education at Tokat Gaziosmanpaşa University Faculty of Dentistry in the 2020-2021 Academic Year. Methods: Within the scope of the study, 146 students in total, who did their face-to-face internship between October 5 and December 11, 2020, were asked to participate in an online survey with 10 questions. Clinical students were asked about their perspective on Covid-19 infection, whether they felt safe in their dental practice, their families' level of anxiety about their internship, and whether they voluntarily chose dentistry. Results: According to the survey results; 15.1% of the students agree (TA), 27.4% agree (A), 37% partially agree (PA), 13% disagree (D) with the statement “I am pleased to have internships since the beginning of the term” 7.5% of them answered, “Strongly disagree” (SD). Pearson’s chi-square test was used in the statistical analysis of the answers given by 4th and 5th-grade students to the first 9 questions of the questionnaire consisting of the same questions. According to the survey results, it was also observed that most students chose the dentistry profession of their own will (TA 39%, A 36.3%, PA 13.7%). The number of students who think they feel safe in terms of infection control during their internship is 60% in total (TA 5.5%, A 17.1%, PA 37.7%). Conclusion: Despite the increasing number of cases until today, it is thought that the process has been successfully managed and that the students have gained experience in practical training, albeit limited.

Abstract: Smoking behavior is an individual activities of lighting and inhaling cigarettes and as a consequence the smoke inhaled by the people around. Epidemiological studies show that there are increasing numbers of cigarette consumption every year followed by the increases of angina pectoris incidences. Unfortunately, the relationship of the number of cigarettes consumed and smoking duration that could cause angina pectoris were still undetermined.  This study aimed to determine the correlation between smoking behavior and the incidence of unstable angina. This was an analytic retrospective study by using cross sectional approach. Samples were angina pectoris patients that admitted in Prof. Dr. R. D. Kandou Hospital Manado from July 2012 to June 2013 by using a purposive sampling technique. The chi-square test showed that there was a significant correlation between the smoking behavior and the incidence of unstable angina based on the numbers of cigarettes smoked per day (P = 0.012) and duration of smoking (P = 0.021) with the duration of chest pain. Conclusion: There was a significant correlation between the smoking behavior based on the numbers of cigarettes consumed per day and the duration of smoking with the incidences of unstable angina based on the chest pain duration. Keywords: smoking behavior, unstable angina   Abstrak: Perilaku merokok adalah suatu aktivitas yang dilakukan individu dengan menyalakan dan menghisap rokok yang menimbulkan asap yang dapat terhisap oleh orang-orang disekitarnya. Penelitian epidemiologik menunjukkan bahwa setiap tahun terjadi peningkatan konsumsi rokok yang diikuti oleh meningkatnya kejadian angina pektoris. Sampai saat ini belum diketahui pasti berapa jumlah batang dan lama konsumsi rokok yang dapat menimbulkan angina pektoris. Penelitian ini bertujuan untuk mengetahui hubungan antara perilaku merokok dan kejadian angina pektoris tidak stabil. Perilaku merokok dinilai berdasarkan jumlah rokok yang dihisap setiap hari dan lama merokok sedangkan kejadian angina pektoris tidak stabil berdasarkan lama nyeri dada (chest pain). Penelitian ini menggunakan studi retrospektif analitik dengan pendekatan cross-sectional. Sampel penelitian ialah pasien angina pektoris tidak stabil di BLU RSUP Prof. Dr. R. D. Kandou Manado periode Juli 2012-Juni 2013 yang diperoleh dengan menggunakan purposive sampling. Hasil uji chi-square menunjukkan bahwa terdapat hubungan bermakna antara perilaku merokok dan kejadian angina pektoris tidak stabil berdasarkan jumlah rokok yang dihisap dalam 1 hari (P = 0,012) dan lama merokok (P = 0,021) dengan lama nyeri dada (chest pain). Simpulan: Terdapat hubungan bermakna antara perilaku merokok dengan kejadian angina pektoris tidak stabil. Kata kunci: perilaku merokok, angina pektoris tidak stabil

The health problems are frequently arise in Islamic boarding school (pesantren) such as the multiple occurrence of infectious diseases. This condition is due to poor hygiene behavior and is exacerbated by the condition of the students’ dormitory environment. One of the alarming health problems in pesantren is Leuchorrea. This study aimed to investigate the correlation between vaginal hygiene behavior and the presence of Candida sp on bathroom water of Islamic Boarding School in Surabaya. This study was an observational study with cross sectional design. The study participants were 100 students selected by using simple random sampling. The correlation between vaginal hygiene behavior and Leucorrhea was analyzed by using Chi-Square Test (α=0,1). The presence of Candida in bathroom water was analyzed descriptively. The result of this study showed that 48 students (48%) were suffering from pathological leucorrhea. Vaginal hygiene behaviors associated to pathological leucorrhea were including of the frequency of changing underwear, p value = 0,014 < α(0,1); the habit of wearing underwear alternately, p value= 0,012 < α(0,01);  student’s way to wash the vagina, p value= 0,001 < α(0,01), the use of tissue after washing the vagina, p value= 0,097 < α(0,01); and the frequency of changing sanitary pads, p value = 0,001 <α(0,1). Candida sp, Candida krusei, and Candida Parapsilosis were found in the bathroom water. The conclusion of this study is some of the vaginal hygiene behaviors were significantly correlated with to pathological leucorrhea, and the presence of Candida sp in bathroom water had a potential to be one of the risk factors of pathological leucorrhea of the boarding school’s students.
