Dynamic thoracoplasty for asphyxiating thoracic dystrophy.

The life-saving procedures to expand the chests of infants born with Jeune asphyxiating thoracic dystrophy provide a static solution incapable of responding to the growth demands of thriving patients. We describe an instrument that provided a dynamic solution for an infant, where an initial methyl methacrylate midsternotomy spacer placed at 4 months of age was followed at 11 months with recurrence of his difficulties. At 8 months after the second operation the patient was stable and thriving with no recurrence of symptoms. The instrument modifications, limitations, and possible complications are described.

A rationale for adjuvant surgical intervention in pyoderma gangrenosum.

Medical specialists who care for patients with pyoderma gangrenosum have been reluctant traditionally to consult plastic surgeons. This is the result of previous negative experience with debridement and skin grafting. However, a new understanding of the pathophysiology of the disease process, and better therapeutic options for control have emerged. Very few studies report the results of surgical therapy of this disease, and fewer yet report successful outcome. The authors present their limited experience at the American University of Beirut with 4 patients who were controlled medically followed by skin grafting their large wounds, thus decreasing their morbidity and hospital stay. A review of the literature together with insights on the rationale and timing of surgery in this particular small group of patients are discussed.

Intercostal thorascopic harvesting of the internal mammary artery for supercharging a pedicled rectus abdominis flap.

Thorascopic harvesting of the internal mammary artery for supercharging the rectus abdominis pedicled flap for breast reconstruction is presented. The procedure was carried on a woman who had previously undergone a mastectomy and who was obese and a diabetic. The patient underwent a "high" flap delay 2 weeks earlier. At the time of operative transfer and setting, the flap's vascularity was found to be compromised. Instead of turbocharging the deep inferior epigastric pedicle to the irradiated axillary vessels, it was possible to harvest and utilize the internal mammary artery without rib resection for the supercharging, thus saving the flap and reconstruction. The technical aspects, and possible advantages and disadvantages of such a procedure are discussed.

Bacille Calmette-Guérin (BCG)-itis of the hand: a potential hazard for health workers.

The bacille Calmette-Guérin vaccine has been used widely for several decades in tuberculosis prophylaxis. More recently, it has been used therapeutically in the management of neoplastic diseases such as malignant melanoma and urinary bladder tumors. Complications of the b. Calmette-Guérin vaccine and therapy are widely reported in the literature. However, its potential hazard to health workers is not well described. We present a case of b. Calmette-Guérinitis on the extensor surface of the left ring finger of a surgical resident following an accidental prick with a contaminated syringe while installing intravesical b. Calmette-Guérin to a patient being treated for a bladder tumor. A brief review of tuberculous hand infection is presented together with its recommended treatment. A review of the various usages of b. Calmette-Guérin is also presented, stressing the various reported complications.

Giant cell tumor (osteoclastoma) of the mandible: a diagnostic dilemma and a therapeutic challenge.

A recurrent giant cell lesion of bone 4.5 years after initial curettage from the mandibular body is described in a 40-year-old premenopausal female patient. Giant cell tumor is exceedingly rare in this location and histologically may be indistinguishable from giant cell reparative granuloma. The treatment rationale for this particular patient was extrapolated from the treatment of giant cell tumor in other more commonly involved bones. En bloc resection is indicated irrespective of the grade or stage of the tumor, provided satisfactory reconstruction can be achieved. The morbidity from tumor treatment should never, in any case, exceed the morbidity from the tumor itself.

Effect of capsulectomy on the hemodynamics and viability of random-pattern skin flaps raised on expanded skin in the pig.

Skin flaps constructed on expanded skin usually include the underlying capsular tissue. It has been hypothesized that capsulectomy may jeopardize the viability of the expanded skin flap. The experiments reported herein were designed to test this hypothesis. Specifically, we studied the hemodynamics and viability of random-pattern skin flaps (8 X 20 cm) raised on delayed bipedicle flaps (group A) and on expanded skin pockets with capsulectomy at the time of flap elevation (group B) or with intact underlying capsular tissue (group C). Each group was randomly assigned to each flank in 16 pigs. Skin pockets were expanded by inflation of subcutaneous silicone tissue expanders with sterile saline (299 +/- 7 ml; X +/- SEM) over a period of 3 weeks. At the end of this period, the bipedicle flaps were constructed. Eight days later, random-pattern skin flaps were raised on bipedicle flaps and skin pockets. The length and area of skin flap viability, judged by the fluorescein dye test performed 1 day postoperatively, were not significantly different (p greater than 0.05) among groups A, B, and C (n = 31 to 32). There also were no significant differences (p greater than 0.05) in total skin capillary blood flow measured 1 day postoperatively (A = 2.6 +/- 0.4, B = 2.4 +/- 0.4, and C = 2.7 +/- 0.6 ml/min per flap; n = 15 to 16) and in skin viability assessed 7 days postoperatively (A = 74 +/- 2, B = 75 +/- 2, and C = 76 +/- 2 percent; n = 16) among delayed skin flaps and skin flaps raised on expanded skin pockets with or without capsulectomy. The results of this flap viability study were confirmed in 5 minipigs in a separate experiment. We conclude that capsulectomy did not have a detrimental effect on the hemodynamics and viability of random-pattern skin flaps raised on expanded skin. Furthermore, we hypothesize that skin flaps raised on expanded skin are similar to delayed skin flaps in that the skin blood flow is optimally augmented; therefore, the capsular tissue does not add significant blood supply to the overlying skin.

Laparoscopic transverse rectus abdominus flap delay for autogenous breast reconstruction.

Laparoscopic ligation of the deep and superficial inferior epigastric vessels was done for ten mastectomized patients who elected to have autogenous reconstruction of their breast. All these patients had at least one indication for the delay which included obesity, smoking, or requirement of a large volume of tissue for their reconstruction. The procedure did not add any morbidity or mortality to our patients and was found to be comparable to the "open" delay in preventing partial tissue loss in all but two patients. We describe the use of a minimally invasive procedure to augment the deep superior epigastric pedicled blood supply for the future transverse rectus abdominus flap. We have found in laparoscopic delay a safe, short procedure that is useful in high risk patients who choose the option of autologous breast reconstruction.
