  • Phlegm smear testing for acid-fast bacilli (AFB) requires careful examination of tubercle bacilli under a microscope to distinguish between positive and negative findings. The biggest weakness of this method is the visual limitations of the examiners. It is also time-consuming, and mistakes may easily occur. This paper proposes a method of identifying tubercle bacilli that uses a computer instead of a human. To address the challenges of AFB testing, this study designs and investigates image systems that can be used to identify tubercle bacilli. The proposed system uses an electronic microscope to capture digital images that are then processed through feature extraction, image segmentation, image recognition, and neural networks to analyze tubercle bacilli. The proposed system can detect the amount of tubercle bacilli and find their locations. This paper analyzes 184 tubercle bacilli images. Fifty images are used to train the artificial neural network, and the rest are used for testing. The proposed system has a 95.6% successful identification rate, and only takes 0.8 seconds to identify an image.

  • Fractures of the zygoma are rarely encountered in pediatric patients. This report presents a case of a 3-year-old child who presented with a vertically split fracture of the marginal tubercle of the zygoma. The marginal tubercle, a bony portion present on the posterior border of the frontal process, assists in attaching the temporalis fascia. This patient was treated surgically with bony fixation using tissue glue. To the best of our knowledge, no cases of fracture of the marginal tubercle of the zygoma have been reported in the literature. Fractures of the marginal tubercle of the zygoma in pediatric patients may be overlooked because of their anatomic location and the musculoskeletal characteristics of these patients. Here, we discuss the clinical features of marginal tubercle fractures of the zygoma.

  • Paramolar tubercle은 드문 발생학적 치아 기형으로 구치의 협면 또는 설면에서 나타나는 추가적인 교두로 정의된다. 영구치에 융합된 Paramolar tubercle의 존재는 근관치료를 어렵게 하는 원인이 될 수 있다. 그러므로 이러한 변이에 대한 적절한 이해가 성공적인 근관치료를 위해 중요하다. 콘빔 전산화 단층 촬영(CBCT)은 복잡한 증례에서 해부학적 구조를 이해하는 데 도움을 줄 수 있다. 따라서 본 증례는 Paramolar tubercle이 융합된 상악 제2소구치의 비외과적 근관치료에 대한 증례에 대해 보고하고자 한다.

  • An enlarged peroneal tubercle causes lateral ankle and foot pain, and which is a cause for stenosing peroneal tenosynovitis. In this report, we present a case of stenosing tenosynovitis of the peroneus longus tendon associated with hypertrophy of the peroneal tubercle without involvement of the peroneus brevis tendon. Surgical excision of the enlarged peroneal tubercle along with exploration of the peroneal tendons was successful.

  • A hypertrophied peroneal tubercle can present as a bony prominence at the lateral aspect of the foot and a peroneal tenosynovitis or tear. We report a case of a 52-year-old man complaining of lateral foot tingling pain and numbness. The sural nerve entrapment and peroneus longus tenosynovitis by hypertrophied peroneal tubercle were confirmed. Good results were obtained after excision of the hypertrophied peroneal tubercle and sural nerve release.

  • The objective of this study was to evaluate the initial detection time and development of the fetal genital structures using ultrasound in twelve pregnant small bitches. The initial detection time of the fetal genital structures was as follows: genital tubercle at days 32.6; os penis at days 45.2; labia at days 45.7; scrotum at days 47.5. Ultrasonograms of fetal genital structure according to gestational stage were as follows: Undifferentiated stage (before day 35), the genital tubercle was observed to have a small elevation and just a hyper-echogenic structure in the midline between the umbilical cord and the tail in male and female fetus. Migration stage (between day 35~45), the genital tubercle was observed as a hyper-echogenic, bilobular, oval shaped and the genital tubercle began to migrate from the initial position toward the umbilical cord in males, and toward the tail in females. Differentiated stage (after day 46), the penis and os penis were observed to stand out in the abdominal wall and the scrotum was observed toward the perineal region in male fetuses. The labia was detected at the base of the tail in female fetuses. These results indicate that ultrasound of fetal genital structures could be useful for fetal gender determination and a completely prepartum evaluation of the canine fetus.

  • Concomitant fracture of medial tubercle of posterior process and lateral process of the talus has not been reported in Korean literature. Association between fracture of lateral and posterior process of talus is not clear. We treated with open reduction and screw fixation in fracture of lateral process and with excision of fragment of posteromedial tubercle of posterior process with satisfying result.

  • The author presents a new method for the formation of Cupid's bow and the vermilion tubercle by using the inferior-based lip skin flap in a secondary bilateral cleft lip deformity. The length of the flap includes the entire length of the previous upper lip scar. Both skin flaps are elevated and turned down toward the central part of the vermilion. The distant portion of the turned-down skin flaps are deepithelialized and trimmed according to the new shape of Cupid's bow. The deepithelialized portions of both flaps are buried under the central vermilion mucosa in order to create the vermilion tubercle. The advantages of the proposed procedure are; provision of a more natural shape of Cupid's bow, the lip length is increased, and the vermilion tubercle can be reconstructed at the same time. Therefore, this technique is best suited for a case of a bilateral absence of Cupid's bow combined with a short lip in a sufficient upper lip of a bilateral cleft lip deformity. The proposed procedure, however, should be avoided in the tight upper lip because of a great deal of tension on the donor.

  • Objective : Obturator neuropathy is a rare condition. Many neurosurgeons are unfamiliar with the obturator nerve anatomy. The purpose of this study was to define obturator nerve landmarks around the obturator foramen. Methods : Fourteen cadavers were studied bilaterally to measure the distances from the nerve root to relevant anatomical landmarks near the obturator nerve, including the anterior superior iliac spine (ASIS), the pubic tubercle, the inguinal ligament, the femoral artery, and the adductor longus. Results : The obturator nerve exits the obturator foramen and travels infero-medially between the adductors longus and brevis. The median distances from the obturator nerve exit zone (ONEZ) to the ASIS and pubic tubercle were 114 mm and 30 mm, respectively. The median horizontal and vertical distances between the pubic tubercle and the ONEZ were 17 mm and 27 mm, respectively. The shortest median distance from the ONEZ to the inguinal ligament was 19 mm. The median inguinal ligament lengths from the ASIS and the median pubic tubercle to the shortest point were 103 mm and 24 mm, respectively. The median obturator nerve lengths between the ONEZ and the adductor longus and femoral artery were 41 mm and 28 mm, respectively. Conclusion : The obturator nerve exits the foramen 17 mm and 27 mm on the horizontal and sagittal planes, respectively, from the pubic tubercle below the pectineus muscle. The shallowest area is approximately one-fifth medially from the inguinal ligament. This study will help improve the accuracy of obturator nerve surgeries to better establish therapeutic plans and decrease complications.
