Intrauterine contraceptive device (IUCD) is one of the most widely used family planning methods. Although considered to be generally safe, it can be associated with problems such as missing IUCD. There have been many reports of isolated missing IUCD but reports of two missing IUCDs in the same patient are very rare. We report the case of a 35-year-old lady with such an occurrence that was diagnosed incidentally on a routine kidney, ureter and bladder (KUB) radiography.

Percutaneous endoscopic gastrostomy (PEG) tube has been used to provide long-term nutritional support for patients who are unable to maintain sufficient oral intake. Buried bumper syndrome (BBS) is an uncommon complication of PEG tube insertion that can be associated with serious complications. We report a case an 82-year-old man who presented with BBS that occurred eight months after PEG tube insertion. The migrated PEG tube was removed and fortunately, the patient's swallowing had improved to allow sufficient oral intake. Clinicians should consider BBS in any patients with PEG tube who present with difficulty with feeding or tube blockage.

The migration and distribution pattern of spargana in mouse body was observed after experimental infection through mouth. The spargana were obtained from the snake, Natrix tigrina lateralis, caught in Hoengseong-gun, Kangwon-do. A total of 28 male mice (ICR strain), 21-25g in body weight, were fed each with 5 scolices (and necks) of spargana and killed after 10 minutes to 14 days. Systemic autopsy was performed on each mouse to recover the spargana. The results are as follows: The spargana were found to penetrate into the stomach or duodenal wall of mice as early as 10 minutes after infection. They completed the penetration within 30 minutes and appeared in abdominal cavity. It was observed that spargana did not migrate tangentially along the gut wall but directly perforated the wall. After 1 hour to 1 day the majority of spargana distributed in abdominal cavity of mice except few which migrated to muscles or subcutaneous tissues. It was within 7 days that nearly all of the spargana migrated to subcutaneous tissues. Out of total 28 in number found from subcutaneous tissues, 13 distributed around neck region, 12 around trunk and other 3 on head of mice and the most common sites were submandibular and subscapular areas. There was nearly no host tissue reaction to migrating spargana. The initial length of spargana given was 4 mm in average but it increased to 12 mm after 7 days and to 35 mm after 14 days. The results suggest that spargana orally given to mice penetrate the gut wall within 30 minutes followed by escaping into abdominal cavity, and after passing through thoracic cavity or abdominal wall they finally localize in subcutaneous tissues chiefly around neck region within 7 days.

Mitochondrial DNA (mt DNA) and the non-recombining region of the Y chromosome are passed down, unaltered, from generation to generation, matrilineally and patrilineally, respectively. Therefore, the Y-chromosome DNA and mtDNA are known as lineage markers, and they play important roles in studies based on human migration and evolutionary history. Y-chromosome DNA is used in forensic analysis to identify individuals involved in cases of sexual assault. In this paper, we review the methods of statistical evaluation of lineage markers used in forensic identification. We also review the combined approach of autosomal and lineage marker evidence.

A single-rod subdermal contraceptive implant is usually located around the insertion site, has been usually known to migrate within less than 2 cm of the insertion site and the true migration over 2 cm has been rarely reported. We report a case of migrated radiopaque subdermal contraceptive implant into lung in a 37-year-old woman. On conducted chest computed tomography, subdermal contraceptive implant was in subsegmental branch in left posterior basal segment of lung. Removal of subdermal contraceptive implant in left posterior basal segment of lung by mini-thoracotomy was performed by a chest surgeon. Complications with insertion and removal of subdermal contraceptive implant are rare in the hands of medical professionals familiar with the techniques and these procedures should only be undertaken by those with relevant training. The migration over 2 cm should not occur if the correct subdermal insertion procedure is followed and carried out by a properly trained individual.

Metallic fixations devices are widely used in the surgical management of fractures and dislocations of shoulder. It is known that Kirschner wire (K-wire) may migrate into the thoracic cavity or other organs may occur. We report a case in which a K-wire previously placed in the clavicle migrated into the thoracic cavity without causing any trauma to the major vascular structures and was removed successfully by thoracoscopic surgery.

The following results were obtained in the present study concerning the effectiveness of thiabendazole upon the larvae of the migrating stages. In the early observation group: The average number of larvae of the group treated with single dose and the group treated with three doses were reduced in proportion of 52.2%, 58.5 % respectively compared with control group. In the late observation group: The reduction rate in the group treated with singel dose and group treated with three doses were 59.3 % and 63.2 % respectively compared with control group. The reduction rates of larvae from liver and lungs in the early drug administration group were 72.9 % and 59.7 % respectively, and 14.9 % and 54.8 % in the delayed drug administration group. In the group of drug given before and after infection, the number of recovered larvae were reduced 42.2 % and 31.1 % respectively compared with the control group. The peak number in organs was delayed 1 to 2 days in the treated group than that of control group. The survival period of the infected mouse was prolonged by the drug administration. The pathological changes were reduced by the administration of the drug. Through above results, it was concluded that thiabendazole reduced the number of migrating larvae and delayed the normal migration of the larvae in tissues and reduced the pathological changes in the tissues.
