BACKGROUND: The stimulation and selection of an effective acupoint is important for producing effective analgesia in electraoacupuncture. This study examined the effect of electroacupuncture to different acupoints and investigated the effective acupoint for ankle-sprained pain in rats. METHODS: A Sprain was produced by manually overextending the lateral ligament of the right ankle in rats. Electrical stimulation was delivered individually to five acupoints: bilateral Yangno (SI6s), contralateral Zusanli (ST36), Hapko (LI4) and Sanyinjiao (SP6). The level of pain evoked by ankle sprain was measured by the stepping force of the sprained paw during walking at pre-sprain and 24 hrs after the sprain. The effect of electroacupuncture was evaluated by the % full recovery of the stepping force at 1, 2, 4 hr after terminating electroacupuncture. RESULTS: Electrical stimulation to SI6 and ST36 among the five acupoints produced a significant increase in the % full recovery of the stepping force of the ankle-sprained paw during walking. CONCLUSIONS: The effective acupoints for electroacupuncture on ankle-sprained pain in rats is SI6 and ST36. These points are relatively specific to ankle-sprain. It is important to select the appropriate acupoint for effective electroacupuncture-induced analgesia.

The incidence of vaccine-type Streptococcus pneumoniae carriage and disease have declined in vaccinated children as well as in unvaccinated children and adults. However, diseases caused by non-vaccine type (NVT) S. pneumoniae are increasing. In this study, we report an invasive pneumococcal disease (IPD) caused by NVT multidrug-resistant (MDR) S. pneumoniae transmitted from a vaccinated infant to an unvaccinated healthy woman, and the clinical characteristics of this serotype. A 29-year-old previously healthy woman visited our hospital with fever and headache. She had been breastfeeding her baby for 8 months. She was diagnosed with brain abscess and sinusitis caused by S. pneumoniae. Although the patient had no previous exposure to antibiotics, antibiotic susceptibility test identified the pathogen as MDR. The patient's family members were examined using nasopharyngeal swabs for bacterial culture. The serotype of S. pneumoniae identified from the blood, abscess, and sputum of the patient was 15B/C. After investing the patient's family members, we found that the serotype from nasopharyngeal specimen of her baby was the same. We described an invasive MDR pneumococcal disease in an immunocompetent young adult in the community. IPD likely spread to the patient by close contact with her baby, who harbored S. pneumoniae of NVT. The spread of NVT S. pneumoniae in the post-vaccine era has increased in the community, and resistance pattern for S. pneumoniae of 15B/C changed compared to the pre-pneumococcal conjugate vaccine era. The spread of MDR pathogens causing IPD among family members should be monitored.

Mycobacterium massiliense (M. massiliense) is a novel nontuberculous mycobacteria (NTM) and an opportunistic pathogen that lives in the water, soil, food, and air. It is a subspecies of the rapidly growing mycobacteria Mycobacterium abscessus. This atypical pathogen has been reported mainly in patients with lung disease or those undergoing cosmetic or surgical procedures. A 62-year-old woman presented with productive otorrhea for 10 months, no history of surgery, and chronic otitis media. M. massiliense was identified from a tissue specimen using real-time polymerase chain reaction for NTM (Biosewoom, Seoul, Korea), and NTM was identified by acid-fast bacilli culture. Successful treatment consisted of clarithromycin for 4 months. No other case of chronic otitis media related to M. massiliense has been reported. This is the first confirmed case of chronic otitis media caused by M. massiliense in a healthy adult in South Korea.

Endoscopic treatment of chronic pancreatitis by stent insertion is an accepted procedure, but various complications can be induced, including proximal migration of the stent. Many techniques are used to retrieve proximally migrated, pancreatic stents. We here report a case of a proximally migrated stent into the dorsal duct of a pancreas divisum, which was retrieved endoscopically by using a mini-snare. A 39-year-old female patient had chronic pancreatitis with divisum. A stent was inserted into the dorsal duct to relieve the chronic pain. After two months, sudden epigastric pain developed due to proximal migration of the stent. The pancreatic stent was retrieved successfully with one endoscopic attempt using a mini-snare. The epigastric pain resolved after retrieval of the stent. Our observation is that pancreatic stent migration may cause severe abdominal pain and that endoscopic retrieval is possible.

Adenosquamous carcinoma of the papilla of Vater is a rare tumor and only a few cases have been reported so far. Here, we report a case of adenosquamous carcinoma in a 76-year-old male who presented with jaundice and right upper quadrant abdominal pain. Ultrasonography and enhanced abdominal CT scans showed dilated common bile duct (CBD) and intrahepatic bile duct (IHD) with a suspicious obstructing mass in distal CBD. On endoscopy, obstructing and ulcerated mass was noted on the papilla of Vater. Histopathological inspection of the biopsied specimens from mass showed adenosquamous cell carcinoma of the papilla of Vater. Since the patient refused operation, we inserted a self-expandable metallic stent in distal CBD. This is the first case report on adenosquamous carcinoma of the papilla of Vater in Korea.
