Objectives: The purpose of this study is to report the three cases of pulsatile tinnitus without any cause improved by acupotomy and acupuncture. Methods: Three patients diagnosed with pulsatile tinnitus with no abnormalities detected on examination were treated with acupotomy and acupuncture. The improvement of symptoms was evaluated by visual analogue scale(VAS). Results: The visual analogue scale has decreased from 7 to 0, from 5 to 1, and from 6 to 0, respectively. Conclusions: Acupotomy had shown a positive clinical effect in the treatment of the pulsatile tinnitus without any cause in this case reports.

Puerperal sepsis is one of the leading causes of maternal morbidity and mortality worldwide. Postpartum pelvic infections can cause various complications, including wound infections and necrotizing fasciitis. Several microorganisms are known to cause such infections; however, no study has reported on Staphylococcus caprae, a coagulase-negative staphylococcus that is isolated frequently from animals and infrequently from human specimens, as a causative agent. Here, we report a rare case of septic shock complicated by necrotizing fasciitis after a cesarean section. This is the first report of a human isolate of S. caprae in association with puerperal sepsis and necrotizing fasciitis.

We present a rare case of medulloblastoma which presented with unilateral sudden sensorineural hearing loss as an initial symptom. A 19-year-old man was admitted to our hospital with a chief complaint of dizziness and facial numbness on the right side. His illness had begun two years previously with sudden hearing loss on the right side, for which he had been treated as an idiopathic sudden hearing loss. Magnetic resonance imaging demonstrated abnormal signals located mainly in the right middle cerebellar peduncle. We performed partial resection of the tumor by suboccipital craniotomy. The histopathological diagnosis was medulloblastoma. Intrinsic brain tumor is an extremely rare cause of sudden sensorineural hearing loss and is therefore easily overlooked as was in the present case. The present case highlights not only the need to evaluate patients with sudden sensorineural hearing loss by magnetic resonance imaging but also the importance of paying attention to intrinsic lesions involving the brainstem. Although this condition like the presented case might be rare, intrinsic brain tumor should be considered as a potential cause of sudden sensorineural hearing loss, as it may be easily missed leading to a delay in appropriate treatment.

Gastrointestinal bleeding is a common cause of hospitalization. Jejunal diverticula is a rare disease and it is an unusual cause of obscure gastrointestinal bleeding. After exclusion of the more common bleeding sources, small bowel diverticula should be considered as a possible rare cause of gastrointestinal bleeding. Jejunal diverticular bleeding is difficult to diagnose and treat because the bleeding site cannot be identified by routine endoscopy and radiologic studies. An exploratory operation is sometimes needed to diagnose and treat obscure gastrointestinal bleeding. If the bleeding site is certain, then surgical resection of the bleeding part of the bowel is the procedure of choice. We report here on a case of jejunal diverticular bleeding that was diagnosed by and treated with surgical resection.

The Markov Chain approach is used to develop an economic adjustment model of a process whose quality can be affected by a single special cause, resulting in changes of the process mean by incorrect adjustment of the process when it is operating according to its capability. The $\bar{X}$ control chart is thus used to signal the special cause. It is demonstrated that the expressions for the expected cycle time and the expected cycle cost are easier to obtain by the proposed approach than by adopting that in Collani, Saniga and Weigang (1994). Furthermore, this approach would be easily extended to derive the expected cycle cost and the expected cycle time for the case of multiple special causes or multiple control charts. A numerical example illustrates the proposed method and its application.

The platform screen door open-close mechanisms at today's subway are divided by "Radio Frequency method" and "Method at entrance perception sensor". In the case of "method at entrance perception sensor", there happen a lot of occasions of malfunctioning that may cause problems in terms of timeliness, swiftness and reliability of train operation and even ends up to train operation stop since the perceiving process is complicated and it is prone to have dust on lenses, position alteration by train vibration, and less reflection light in the case of new train. In this study, we find how to minimize possible problems in terms of maintenance during train operation period, and seek its alternatives in order not only to have no malfunction in perception but also to cause no disturbance in train operation through dealing organically when perceiving door open-close to minimize delay time.

Venous aneurysms are uncommon in the lower limb and are more frequently found in the neck and thoracic and visceral veins. However, they have been reported to cause thrombosis, pulmonary thromboembolism, and other related complications. Popliteal venous aneurysms are often undetected because they are usually asymptomatic, but they may cause pulmonary thromboembolic events. We experienced a case of a 44-year-old man who was referred for recurrent pulmonary thromboembolism. He showed no other symptoms or signs except shortness of breath. A popliteal venous aneurysm was diagnosed incidentally because the examinations were performed to detect a deep vein thrombosis in relationship to the patient's history of pulmonary thromboembolism. We report a case of surgical treatment for a popliteal venous aneurysm that was complicated by pulmonary thromboembolism.

After treating a patient suffering from metacarpophalangeal joint extension disturbance which is caused by posterior interosseous nerve palsy, some results are gained as follows. The symptom of posterior interosseous nerve palsy is simillar to the it of radial nerve palsy. But posterior interosseous nerve palsy isn't accompany with wrist drop. posterior interosseous nerve palsy is accompany with metacarpophalangeal joint extension disturbance. This symptom is caused by posterior interosseous nerve palsy. Posterior interosseous nerve palsy is correspond to MAMOKBULIN(麻木不仁), SUTONG(手痛), SUGI(手氣) in oriental medicine. The cause of this case on oriental medicine is Deficiency of qi and blood. Treatment which based on cause of oriental medicine-herb medication, acupuncture treatment- have a good effect to patient.

Chromosomal loss in trisomy (trisomy rescue) to generate a disomic fetus can cause confined placental mosaicism and/or feto/placental mosaicism. After trisomy rescue event, there is a risk of fetal uniparental disomy (UPD). Noninvasive prenatal test (NIPT) reflects the genomic constitution of the placenta, not of the fetus itself. Feto-placental discrepancy can therefore cause false-positive (trisomy) NIPT results. These discordant NIPT results can serve as important clues to find UPD associated with confined placental mosaicism. We report a case with maternal UPD of chromosome 20, detected by NIPT of 1,000 high-risk pregnancies, carried out for detecting chromosomal abnormalities in Koreans.

Kienböck disease, a rare disease that can cause chronic pain and motor dysfunction, occurs due to avascular necrosis of the lunate bone, which leads to dislocation of the carpal bone. Among various other etiologies, Kienböck disease can cause closed tendon rupture of the finger. In this report, we introduce a case of total rupture of the second extensor digitorum communis and the extensor indicis proprius tendons caused by undiagnosed Kienböck disease in an elderly female patient.
