The purpose of this study was to assess the effectiveness of nasopalatine nerve block for anesthesia of maxillary central incisors after failure of the anterior superior alveolar nerve (ASAN) block technique. Secondarily, the possible innervation of the maxillary central incisors by the nasopalatine nerve was also investigated. Twenty-seven healthy, young adult volunteers (age: 17-26 years; gender: 9 males and 18 females) were enrolled in this study. All participants were undergraduate dental students of the University of Vale do Rio Verde de Três Corações. The volunteers had the anterior superior alveolar nerves anesthetized and a thermal sensitivity test (cold) was performed on the maxillary central incisors. The volunteers that responded positively to cold stimulus received a nasopalatine nerve block and the thermal sensitivity test was repeated. All participants were anesthetized by a single operator. Three patients presented sensitivity after both types of bilateral blocks and were excluded from the percentage calculations. In the remaining 24 patients, 16 had their maxillary central incisors anesthetized by the anterior superior alveolar block and 8 remained with sensitivity after the ASAN block. All these 8 patients had their maxillary central incisors successfully anesthetized by the nasopalatine block. In this study, 33.3% of the subjects had the innervation of one or both maxillary central incisors derived from the nasopalatine nerve, whilst most subjects (66.7%) had such teeth innervated by the anterior superior alveolar nerve. The nasopalatine nerve block was effective in anesthetizing the maxillary central incisors when the anterior superior alveolar nerve block failed.

ABSTRAKPada studi ini dilakukan rancang bangun sistem perekam detak jantung portabel berbasis pulse heart rate sensor. Studi ini bertujuan untuk mengetahui keakuratan pulse heart rate sensor dalam mendeteksi detak jantung pada jari tangan, dimana tahap selanjutnya sistem ini akan digunakan untuk merekam detak jantung pasien seharian dalam kondisi beraktivitas. Sistem ini dirancang menggunakan modul pulse heart rate sensor yang dihubungkan dengan mikrokontroller Arduino Nano. Data detak jantung direkam pada modul SD Card. Hasil pengukuran sistem ini dibandingkan dengan hasil pengukuran alat Oxymeter. Pengujian dilakukan dengan mengukur detak jantung bagian jari tengah dengan alat Oxymeter dan bagian jari telunjuk dengan sistem ini. Pengujian dilakukan masing-masing satu kali pada 2 jari tangan kanan dan tangan kiri dari 30 orang naracoba dengan rentang usia 18-23 tahun. Hasil pengujian menunjukkan rata-rata error akurasi sistem ini adalah 2 bpm terhadap Oxymeter dengan selisih terbesar 5 bpm. Kata kunci: detak jantung, jari tangan, Oxymeter, SD Card, sensor pulse heartrate. ABSTRACTIn this study, we implemented a portable pulse heart rate sensor based heart beat recording system. The goal of this study is to evaluate an accuracy of the sensor for detecting the heart beat on both a right finger and a left finger in order to implement an ambulatory heart beat recording system. The pulse heart rate sensor was connected to an Arduino Nano contoller module to calculate the heart beat. The heart beat was then recorded in a SD Card module. The system’s results were compared to an oxymeter. Thirty healthy young adult volunteers were involved in this study by measuring the heart beat on a middle finger with Oxymeter and on an index finger with our system. The measurement was tested on both hands’s fingers. The results showed that an accuracy of the system is 2 bpm relative to the Oxymeter’s with the biggest difference of 5 bpm.Keywords: fingers, heart rate, Oxymeter, pulse heart rate sensor, SD Card

Fractal Approach

Summary Aim: We demonstrate the heterogeneity of regional cerebral blood flow using a fractal approach and singlephoton emission computed tomography (SPECT). Method: Tc-99m-labelled ethylcysteine dimer was injected intravenously in 10 healthy controls and in 10 patients with dementia of frontal lobe type. The head was imaged with a gamma camera and transaxial, sagittal and coronal slices were reconstructed. Two hundred fifty-six symmetrical regions of interest (ROIs) were drawn onto each hemisphere of functioning brain matter. Fractal analysis was used to examine the spatial heterogeneity of blood flow as a function of the number of ROIs. Results: Relative dispersion (= coefficient of variation of the regional flows) was fractal-like in healthy subjects and could be characterized by a fractal dimension of 1.17 ± 0.05 (mean ± SD) for the left hemisphere and 1.15 ± 0.04 for the right hemisphere, respectively. The fractal dimension of 1.0 reflects completely homogeneous blood flow and 1.5 indicates a random blood flow distribution. Patients with dementia of frontal lobe type had a significantly lower fractal dimension of 1.04 ± 0.03 than in healthy controls. Conclusion: Within the limits of spatial resolution of SPECT, the heterogeneity of brain blood flow is well characterized by a fractal dimension. Fractal analysis may help brain scientists to assess age-, sex- and laterality-related anatomic and physiological changes of brain blood flow and possibly to improve precision of diagnostic information available for patient care.
