Laparoscopic subtotal gastric resection for chronic gastric ulcers.

OBJECTIVES: We analyzed our experience with the laparoscopic approach for treating benign gastric lesions. METHODS: Between June 1998 and June 2002, we performed 18 gastric resections with the laparoscopic approach for 7 pyloric stenoses, 8 recurrent duodenal ulcers, and 3 chronic gastric ulcers. RESULTS: In our series, we performed Billroth II laparoscopic distal gastrectomy with no morbidity and mortality. CONCLUSIONS: Billroth II laparoscopic distal gastrectomy is safe in cases of benign gastric or duodenal lesions.     

Differential diagnosis of leg ulcers

In Germany about 0.7 % of the adult population have a chronic leg ulcer. Although chronic venous insufficiency accounts for at least 80 % of all chronic leg ulcers, knowledge of the relevant differential diagnostic considerations is of crucial importance, in particular for patients who are refractory to therapy. In addition to vascular disease, other causes include neuropathic, metabolic, hematologic and exogenous factors as well as neoplasias, infections, drugs, genetic defects and some primary skin disorders. For the long‐term successful treatment of patients with chronic leg ulcers, it is necessary to identify all relevant factors, in order to enable a pathogenesis‐oriented, interdisciplinary therapeutic approach.     

Basic fibroblast growth factor and epidermal growth factor reverse impaired ulcer healing of the rabbit oral mucosa

BACKGROUND: The therapies for refractory ulcers on the oral mucosa are symptomatic and very unsatisfactory. We hypothesized that application of growth factors might be able to achieve successful remission of the lesion. We evaluated the effects of systemic administration and topical application of epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF) on impaired wound healing of ulcers in the rabbit gingiva. METHODS: Almost uniform round ulcers could be created on the gingiva of the rabbits by chemical injury with acetic acid. When the submandibular glands were removed or i.v. injection of cisplatin (CDDP) and peplomycin sulfate was performed before ulcer formation, healing of the ulcers took longer than in untreated rabbits. To ascertain whether or not human EGF and bFGF affect rabbit cells, we first examined the effects of EGF and bFGF on the proliferation of the cells derived from rabbit gingiva. We then applied EGF or bFGF in these impaired healing models. RESULTS: EGF and bFGF promoted proliferation of the fibroblasts, and EGF also promoted proliferation of the keratinocytes isolated from gingival tissue of rabbits in vitro. Systemic injections of EGF and bFGF in rabbits, which had their submandibular glands removed, and topical application of bFGF accelerated healing of ulcers created in rabbits injected with CDDP and peplomycin sulfate. The ability of bFGF to promote the healing of ulcers was much greater than that of EGF. CONCLUSION: Basic FGF may be effective for refractory oral mucosal lesions.

Pedicled deltoid hatchet flap for treatment of pressure sore at the shoulder

Whereas decubitus ulcer in the back or hip region is a common entity in plegic or elderly patients, the occurrence in the lateral shoulder region is seldom seen. However, resulting from continuous lateral decubitus positioning or limited compliance by the patient, pressure sores may occur in almost any region of the body, but predominately, they arise in acral zones with underlying bone prominences. The deltoid area is such an anatomically critical region, especially if the underlying deltoid muscle is paralyzed. The transposition of a pedicled deltoid flap, slightly modified as a hatchet flap, is described for cover of a decubitus ulcer in the deltoid region in a paraplegic male. Although utilization of the deltoid flap as a free flap is an established procedure for selected indications [Russell et al. (1985) Extremity reconstruction using the free deltoid flap. Plast Reconstr Surg 76:586–595, Serafin D (1996) The deltoid flap. In: Serafin D (ed) Atlas of microsurgical composite tissue transplantation, chapter 19. Saunders, Philadelphia, PA, pp 153–159, Wang et al. (2003) The free deltoid flap: microscopic anatomy studies and clinical application to oral cavity reconstruction. Plast Reconstr Surg 112:404–411], transposition as a pedicled flap, to the best of our knowledge, has not been previously described in the available literature.     

103例角膜溃疡的病因和病原及药物敏感试验的统计分析

对１９９５年１—１２月间我院门诊１０３例角膜溃疡的病因、病原和药物敏感试验进行统计分析。病因：外伤５９例（５７．２８％），继发感染３４例（３３．０１％），原因不明８例（７．７７％），戴接触镜２例（１．９４％）。病原：真菌３５例（３３．９８％），绿脓杆菌１８例（１７．４８％），金黄色葡萄球菌１５例（１４．５６％），表皮葡萄球菌９例（８．７４％），淋球菌２例（１．９４％）。对１９例真菌性角膜溃疡同时进行细菌培养，有７例为混合感染，占３６．８４％。对几种主要检出菌的药物敏感试验表明：它们对普通抗菌素均可产生一定的耐药性     

Anorectal function in the solitary rectal ulcer syndrome

The anorectal function of nine patients with solitary rectal ulcer syndrome (SRUS) (5 F: 4 M, median age, 27 (range, 19–41 years) and nine control subjects (5 F: 4 M, median age, 47 (35–66)P<0.01) has been investigated by a new technique that radiologically visualizes the anorectum during voiding of a semisolid contrast medium, while simultaneously measuring intrarectal pressure and anal sphincter EMG activity. A degree of rectal prolapse was demonstrated in eight of the SRUS patients; six of these lesions were clinically occult. Abnormal failure of the anal sphincter to relax on voiding was present in seven of the SRUS patients. These abnormalities resulted in the SRUS patients requiring a greater increase in intrarectal pressure (median, 100 cm water) to void than the control subjects (median, 65 cm water,P<0.01). This combination of high intrarectal pressure and rectal prolapse during straining seems to be the cause of SRUS This work was supported by a grant from the Medical Research Council.
