The Ryukyu long-furred rat, Diplothrix legata, is a large rodent distributed only on Amami-ohshima Island, Tokuno-shima Island and Okinawa-jima Island, Japan. This animal is endangered as a result of deforestation, predation by introduced carnivores and mortality caused by vehicles. We performed theriogenological examinations of 32 male and 25 female Ryukyu long-furred rats carcasses collected ...

Obviously, restoring the nasal lining is a great challenge in the reconstruction of nasal defects. Full thickness nasal defects usually require special flaps for reconstructing the nasal lining. Intranasal mucosal flaps, hinge over flaps, perinasal second flaps, folded or second forehead flaps and finally free flaps are examples that can be used for this purpose. Moreover, the case presented in...

Restoring the intestinal continuity of an acquired massive cervico-thoracic oesophagus defect is a reconstructive challenge. A case requiring such defect restoration following a failed pedicled colonic interposition bypass graft between the cervical oesophagus and stomach for an intra-thoracic oesophageal perforation is presented. The defect between the oesophagostome at the lower left neck and...

Rectangular flaps on the rat or mouse dorsum are frequently used for flap survival elongation research. However, since rectangular flaps are purely random, the survival rate varies among individuals. A reliable animal flap model with low individual variation is desirable for flap survival research, especially in the angiogenic field. We investigated the survival rate of paired flaps in the rat ...

We treated 11 patients with chronic osteomyelitis of the tibia or the foot by local excision and transfer of a peroneal myocutaneous island flap. This flap, pedicled proximally or distally on the peroneal artery and veins, provides viable muscle to fill the dead space in bone and skin to close the defect. Ten patients reviewed more than three years after operation were all free of drainage with...

BACKGROUND The reconstruction of ankle and heel defects remains a significant problem for plastic surgeons. The following options exist for reconstructing such defects: local random flaps, reverse flow island flaps, and free flaps. However, each of these methods has certain drawbacks. Peroneal artery perforators have many advantages; in particular, they are predictable and reliable for ankle an...

This study compares sensory recovery after total lower lip reconstruction in a wide variety of flaps including bilateral depressor anguli oris flap, submental island flap, bilateral fan flaps, radial forearm flap, and pectoralis major myocutaneous flaps in a large number of patients. Spontaneous return of flap sensation was documented by clinical testing in the majority (3%) of patients who und...

BACKGROUND Preputial calculi are rarely encountered in childhood. CASE CHARACTERISTICS A 5-year-old boy with symptoms of chronic balanoposthitis. OBSERVATION A preputial stone was documented and removed at circumcision. OUTCOME Uneventful postoperative recovery. MESSAGE In children, association between phimosis and neurologic impairment represent predisposing condition for preputial sto...
