A study was made of the respiratory effects of acute carbon monoxide poisoning in mongrel dogs. In this study the dogs were divided into two groups, namely the control and the experimental. In the experimental group, carbon monoxide poisoning was induced by the rebreathing of about 2% carbon monoxide gas mixture for 15 minutes, and the respiratory functions in this group were compared to those in the control group. A significant increase in the minute ventilation was noted in both the control and the experimental groups, and in the latter there was an increase in the respiratory rate and a decrease in the tidal volume compared to those in the control group. In both groups, oxygen consumption showed no significant change and there was a fall in the arterial carbon dioxide tension, but the carbon dioxide elimination was slightly lower in the experimental group.

Purpose: To report the surgical skills needed, and the clinical results of, minimally invasive hip surgery with dynamic hip screws and the comparison with the classical technique in stable pertrochanteric fractures of the femur. Materials and Methods: Thirty-two patients with pertrochanteric fractures of the femur who were treated with dynamic compression hip screws between April 1999 and March 2004, and were evaluated retrospectively, and were followed up for more than 12 months. 16 cases were treated with a classical dynamic hip screw technique and 16 cases with a minimally invasive technique in random order. The mean age was 73.2 years, and there were 11 males and 21 females. The operative times, total hemovac bleeding loss, functional scores, and average hemoglobin decrease ratios were evaluated. The clinical assessments were performed with the Harris Hip Score (HSS) and bony union was evaluated with serial follow-up plain radiographs. Results: The average operative time was 63.9 minutes with the classical technique and 42.5 minutes with the minimally invasive technique. The total average hemovac blood loss was 640 cc with the classical technique and 143 cc with the minimally invasive technique. Clinically, the HHS was an average of 85.9 and 89.2 in groups 1 and 2, respectively, by the last follow-up and there were no statistically significant differences between the two groups (P <0.05) The hemoglobin decrease ratio was the same in both groups and there was no nonunion. Conclusion: Minimally invasive dynamic hip screw insertion was useful in stable pertrochanteric fractures, because it decreased blood loss and operative times; and there were no changes in fracture healing and functional outcomes.

BACKGROUND: Redundant and wrinkled face is a common finding in patients with long-standing leprosy, which is responsible for the appearance of premature aging. Chemical peeling plays a role in dermal regeneration in the treatment of wrinkles. However, the effect of chemical peeling has rarely been studied in patients with leprosy. OBJECTIVE: To investigate the effect of chemical peeling on dermal connective tissue components and clinical improvement of facial wrinkles in patients with leprosy. METHODS: Five patients with clinically and bacteriologically inactive lepromatous leprosy were treated with 70% glycolic acid plus 35% trichloroacetic acid (GA-TCA). Histologic and clinical changes were evaluated at 0 and 90 days postpeel. RESULTS: Histologically, collagen fibers and ground substance increased significantly but elastic fibers did not change at 90 days postepeel. Clinically, fine wrinkles improved considerably, whereas most deep wrinkles remained unchanged at day 90. CONCLUSION: This study demonstrates that chemical peeling with GA-TCA, or medium-depth peeling, causes an increase in collagen and ground substance but not in elastic fibers. These changes result in limited clinical improvement in the facial wrinkles of leprosy patients. Therefore, medium-depth chemical peeling may be insufficient to improve the premature aging appearance in patients with leprosy.

Recently, there has been a strong decrease in the number of temporalis muscle transfer(TMT) operations in cases of lagophthalmos. The primary cause of this decline is patient dissatisfaction with drawbacks of eye clinching in concert with mouth closure, ectropion and ptosis. This is mostly true of patients who are now more commonly exposed to urban social environments. In 1997, I discontinued the use of TMT as part of my combination treatment method reported in this journal. Since 1998, I have removed the fascia in 20 TMT cases due to complications in the upper and lower eyelid areas. I then corrected these complications using my combination method. I still use TMT in cases of lower lip drooping. Lagophthalmos patients are treated using my combination method of gold lid loading in the upper eyelid and Alloderm insertion in the lower eyelid through fixation of both ends to the medial and lateral canthal ligaments respectively. Previously, I recommended the use of conchal cartilage but noted the complication of cartilage warping which caused creating new partial ectropion several months later. Alloderm has shown no complications and the results of its use remain most satisfactory.

Paralytic lagophthalmos and ectropion in the treatment of leprosy patients are serious complications of facial paralysis, which may lead to exposure keratitis and corneal ulceration, which can further lead to blindness. In 1995, 1997, 1999 and 2001, we reported in this journal on the surgical treatment of paralytic lagophthalmos and ectropion. In the 1st report, made in 1995, for lid closing, I (Ahn) performed various methods of traditional surgery such as temporal muscle transfer, medial and lateral canthoplasty, as well as gold implantation. In the 2nd report, made in 1997, we (Ahn and Park) presented a combination treatment of gold plate with minor changes of design and weight in the upper lid and medial canthoplasty with horizontal shortening in the lower lid. In the 3rd report, made in 1999, we described an additional graft of conchal cartilage in the lower lid. However, the lateral end of the cartilage would warp and create new partial ectropion several months later. Therefore, we shifted from cartilage to Alloderm(R), acellular dermal graft. In the 4th report, made in 2001, we reported that Alloderm(R) is a good substitute for the cartilage and is also an effective volume filler to the atrophic lower lid. The medial portion of the lower lid often presented with a recurrence of the ectropion, despite having tightened the bilateral plication of the medial and lateral canthal ligaments with an Alloderm(R) graft in the inferior border of the tarsus. In order to treat the recurring ectropion, a modified permanent tarsorrhaphy was performed. We have noted that a modified permanent tarsorrhaphy on the medial canthal area in Z-plasty successfully corrected the partial ectropion and resulted in decreased epiphora and increased esthetic satisfaction.

BACKGROUND: Eyelash ptosis(ELP) is a common finding in patients with long-standing leprosy. However, it has rarely been reported in the literature previously, because it has been diagnosed as trichiasis or entropion. OBJECTIVE: To determine the prevalence of ELP in Hansen's disease. METHODS: We took both frontal and lateral photographs of eyes in 20 patients and evaluated the degree of ptosis using a 4-point rating scale, in which 0 indicates no ptosis; 1, minimal; 2, moderate; and 3, severe. The evaluation was also performed in 20 normal persons as control group. RESULTS: All patients demonstrated ELP. In general, severity of ptosis in patient group is greater than that in control group. While the mean eyelash ptosis rating was 2.0+/-0.6 in the latter, it was 0.6+/-0.4 in the former, which is statistically significant (p<0.01). CONCLUSIONS: ELP is common in the patients with Hansen's disease and moderate to severe forms occurred more commonly in disease group compared with control group. ELP must be considered as a characteristic ocular finding in long-standing leprosy.

Changes in the eye resulting from leprosy include lagophthalmos, ectropion and the eyelid retraction. In lagophthalmos, an interpalpebral gap(lid gap) of 2mm or less, which is most preferred after correction, does not have any adverse effect on the vision. However, a gap of 3mm or greater can cause or make the eye susceptible to the dryness of the cornea or other vision problems. Bell's phenomenon will adequately prevent eye damages, especially corneal damage when the lid gap is less than 3mm. Although static methods such as autogenous canthal sling, lateral tarsal strip, medial tarsorrhaphy and gold implant had a positive cosmetic effect when used in combination, the lid gap could hardly reduce to less than 3mm. Frequent recurrence of lagophthalmos and ectropion after static methods required further definite surgical treatment. We applied a dynamic method of modified Gillies to correct lagophthalmos and it was successful in reducing the lid gap to less than 2mm in most cases.

Acquired tufted angioma is a benign, progressive vascular lesion that has a distinctive histopathologic appearance. We report a 31-year-old man with acquireed tufted angioma. Several reddish papules and plaque were present on the neck. The lesion had been present for 6 months. They had enlarged slowly, and were slightly tender. Histopathologic examination of the biopsy specimen showed round to ovoid cellular tufts of capillaries, most prominent in the middle to lower dermis.

BACKGROUND: Ulnar nerve palsy in patients with Hansen disease causes hand wasting and atrophy. To masquerade these deformities, patients injected paraffin or silicone into the lesions, which results in paraffinomas. Several years later, painful inflammation, ulceration or abscesses may develop in the paraffinomas. OBJECTIVE: To investigate the clinical characteristics of paraffinomas in patients with Hansen disease, and to evaluate and compare the effects of various surgical treatment methods of paraffinomas. METHODS: Fifty-seven patients with paraffinomas were randomized to receive debridement(curettage) with primary closure, skin graft, skin flap, or second intention at the hospital of Korean Hansen Welfare Association from 1998 to 2012. We analyzed retrospectively the final cosmetic results of three methods, primary closure, skin graft, and skin flap, in 33 patients with more than 6 months follow-up. The final results were classified into 4 grades, excellent, good, fair, and poor. RESULTS: Of 57 patients, the ratio of male and female was 42:15 and the average age was 73 and 71 years repectively. The location of the lesions was the hand and wrist in 54 patients and the face in 3. The total number of procedures was 72 and that of 3 methods was 55. In 33 patients, 19 showed above fair grades and the recurrence rate was 42%(14/33). There were no serious postoperative complications. CONCLUSION: Wide and thorough curettage as debridement was very important to reduce recurrence and the primary closure was most efficient in consideration of an old age of patient, simplicity of procedure and cosmeosis.
