Nonincisional Osteotomy for Gradual Lengthening by Callus Distraction for Congenital Brachymetatarsia.

Gradual lengthening by distraction osteogenesis is widely used for congenital brachymetatarsia. The usual presenting complaint is the patient's cosmetic appearance. Osteotomy is an integral element. A nonincisional surgical approach for osteotomy can reduce dorsal longitudinal scarring and help preserve the periosteal blood supply to the bone during surgical dissection. Between June 2003 and January 2019, we performed gradual lengthening by callus distraction with nonincisional osteotomy for congenital brachymetatarsia on 13 digits in 5 patients. All 5 patients were female, and their average age was 18 years old. The lengthened bones involved 3 first metatarsals, 2 third metatarsal, and 8 fourth metatarsal bones. The mean gain in length was 15.2 mm (10-21 mm). The mean duration of distraction was 36.2 days (30-48 days). The mean duration of consolidation was 62.8 days (28-103 days). The lengthened segment consolidated in all cases. One patient had early consolidation and did not wish to undergo further surgery. There were no cases of trouble due to drilling for osteotomy. All patients had a normal gait and were satisfied with the cosmetic results.

Externalized Mesentery Monitoring of Vascularized Jejunum Transfers.

PURPOSE: The use of externalized jejunal monitoring flaps for jejunum transfers could be facilitative for the direct clinical assessment. Although this monitoring method would seem to be highly reliable, we modified this method and used mesentery only as a monitor to make it easy to manage the monitor more. METHODS: Between 2013 and 2018, 43 patients underwent vascularized jejunum transfer for reconstruction of laryngopharyngectomy using the externalized mesentery monitor. There were 39 men and 4 women, and patient ages ranged from 40 to 80 years (average, 66.6 years). The nursing staff monitored the externalized mesentery by using handheld Doppler ultrasonography every 2 hours for 7 days after surgery. RESULTS: Three patients had rather weak signal of handheld Doppler ultrasonography on the externalized mesentery monitors during operation, and handheld Doppler ultrasonography could not be applied. Of the remaining 40 patients using the externalized mesentery monitor with handheld Doppler ultrasonography, 39 had an uncomplicated postoperative period. In 1 patient, no signal of Doppler ultrasonography and lack of bleeding by pin prick from the monitor segment were noted in the immediate postoperative period, and revision of the vascular anastomosis was performed. Finally, the graft was salvaged. There was no case of infection in the monitoring flap or hypertrophic scar at the resected part of the flap. CONCLUSIONS: Using the externalized mesentery monitoring flaps, clinical monitoring by examining the exteriorized monitoring flap is possible, and only mesentery monitors were managed easily compared with jejunum monitoring flaps.

Rhinoplasty for post-traumatic deviation of the nose with non-incisional external perforated osteotomy.

Osteotomy is often necessary for the repair of post-traumatic nasal bone deformities. Typically, tools such as chisels are used for osteotomies; however, we performed osteotomies using Kirschner wires without making a skin incision. Between April 2011 and July 2022, we performed rhinoplasty with external perforated osteotomy using Kirschner wires in 13 patients with post-traumatic nasal bone deformities (9 males and 4 females; mean age, 34 years, range 12-51 years), all of whom exhibited improvement, with only one case showing mild residual cosmetic deformity. None of the patients requested further revision, and all were satisfied with their functional results. The non-incisional external perforated technique is a reasonable method that allows for bone osteotomies along the fracture line and is well-controlled, predictable, and reproducible.

Reconstruction of E. coli Osteomyelitis of Costa: A Case Report.

We report a case of E. coli osteomyelitis of the ribs in an immunocompetent 66-year-old man. After radical surgical debridement, bone and soft-tissue defects were covered with a rectus abdominis muscle flap. The postoperative course was uneventful, and there was no recurrence of chest symptoms. Among the various types of osteomyelitis, Gram-negative bacteria such as E. coli osteomyelitis is a relatively rare disease. Osteomyelitis is known to supervene in trauma or postoperative infection and to frequently begin with cellulitis, vascular access, endocarditis, or urinary tract infection, which spreads through the blood to the bone. To add to the difficulty of making a correct diagnosis, the early symptoms of osteomyelitis are often non-specific. We should never forget osteomyelitis in the differential diagnosis of these antecedent infections.

Reconstruction of the Midfoot Area with Vascularized Chimeric Osteocutaneous Scapula Flap: A Case Report.

We report a case of reconstruction of a left midfoot defect with a chimeric partial scapula and skin flap in a 20-year-old man. After radical debridement, bone and soft tissue defects were reconstructed with a chimeric scapula and skin flap. The postoperative course was uneventful. The patient could walk well without support, and bone union was achieved 6 months after surgery. In 14 months of follow-up, no clinical complications (including new ulcer or stress fracture) were noted and full ambulation was achieved, with the patient returning to his previous work. We suggest that the chimeric scapula and skin flap may be a useful alternative option for midfoot reconstruction.

Methotrexate-associated lymphoproliferative disorder with histopathological features of histiocytic necrotizing lymphadenitis.

An 84-year-old Japanese woman suffering from rheumatoid arthritis (RA), who had been treated with methotrexate (MTX) for 15 years, was admitted to our hospital for generalised lymphadenopathy, thrombocytopenia, anaemia, elevated aminotransferases, and elevated CRP levels. Pathological findings of cervical lymph node biopsy were compatible with histiocytic necrotising lymphadenitis (HNL). Small lymphocytes positive for Epstein-Barr virus (EBV)-encoded small RNA were detected in the tissue. We suspected a MTX-associated lymphoproliferative disorder (MTX-LPD), withdrew MTX and administered leucovorin (folic acid). The patient's symptoms gradually resolved following discontinuation of MTX. We considered that this patient developed HNL as an MTX-LPD when EBV was reactivated. This is the first case of HNL associated with MTX treatment for RA, which we report here along with clinical course.

A case of small bowel obstruction due to infection with Bolbosoma sp. (Acanthocephala: Polymorphidae).

A case of small bowel obstruction caused by Bolbosoma sp. infection is reported. A 27-year-old woman admitted with abdominal pain was diagnosed as small bowel obstruction. Laparoscopic surgery revealed induration in jejunum at ca. 120 cm distal to the ligament of Treiz, attributed to a band connecting the serosa to the ascending mesocolon. Resected band contained an acanthocephalan accompanying foreign body reaction with abscess formation. The parasite belonged to the genus Bolbosoma, of which identification was made by DNA sequence analysis. This is the eighth case of Bolbosoma infection in humans, and the first one causing an ileus.
