Retrograde esophageal balloon dilatation for caustic stricture in an outpatient clinic setting. (1/274)

Caustic injury to the esophagus, with resultant esophageal stricture, is a challenge for the surgeon. These strictures require multiple esophageal dilatations, which are usually performed under general anesthesia and frequently under fluoroscopic control. Because of the risks of multiple general anesthetics and frequent radiation, a technique is described for retrograde esophageal balloon dilatation in an outpatient clinic setting without a general anesthetic or fluoroscopic control.  (+info)

Loss of fenamate-activated K+ current from epithelial cells during corneal wound healing. (2/274)

PURPOSE: The corneal epithelium provides a barrier between the external environment and the cornea. It also serves as an ion transporting epithelium. Because of its proximity with the external environment, the corneal epithelium is frequently injured through physical or chemical insult. The purpose of this study was to determine whether corneal epithelial cell whole-cell currents change during corneal wound healing as the author of the present study has previously reported for corneal keratocytes and endothelial cells. METHODS: Rabbit corneal epithelial cells were injured by scraping, heptanol exposure, or freezing. The epithelium was allowed to heal for 12 to 74 hours. Cells were dissociated from corneas, and whole-cell currents were examined using the amphotericin-perforated-patch technique. RESULTS: Cells from the wounded corneal groups had significantly increased capacitance values, indicating increased surface area compared with that of control cells. As previously reported, the primary control whole-cell current was a fenamate-activated K+ current. An inwardly rectifying K+ current and a Cl- current were also observed. In epithelial cells from heptanol-wounded corneas, these conductances were generally unchanged. In cells from scrape- and freeze-wounded corneas, however, the fenamate-activated current was absent or significantly attenuated. CONCLUSIONS: As they do in corneal keratocytes and endothelial cells, K+ channels disappear during some models of corneal epithelial wound healing. In addition, cell capacitance, a measurement of cell surface area, increases. These results suggest that substantial K+ channel activity is not required for in vivo epithelial cell proliferation during corneal wound healing.  (+info)

The development of Lewisite vapour induced lesions in the domestic, white pig. (3/274)

Studies performed in the past in our laboratory have detailed the development of sulphur mustard lesions in the domestic, white pig using small glass chambers to achieve saturated vapour exposure under occluded conditions. We have now used this experimental model to produce cutaneous lesions for detailed histopathological studies following challenge with lewisite. Histological examination of resulting lesions have revealed that although the overall pattern of lesion development is similar to that seen following mustard challenge, the time-course of cellular events is very much compressed. The epidermis showed focal basal cell vacuolation with associated acute inflammation as early as one hour postexposure. Coagulative necrosis of the epidermis and papillary dermis was complete by 24 hours and followed the appearance of multiple coalescent blisters between six and 12 hours post-exposure. At 48 hours, the lesions were full thickness burns with necrosis extending into the deep subcutaneous connective and adipose tissues. The study of lesions beyond 24 hours revealed early epithelial regeneration at the wound edge. The overall spontaneous healing rate of these biologically severe lesions was significantly faster than comparable sulphur mustard injuries and probably reflected a lack of alkylation of DNA and RNA.  (+info)

Amniotic membrane transplantation for ocular surface reconstruction. (4/274)

AIMS: To evaluate the efficacy of amniotic membrane transplantation (AMT) for ocular surface reconstruction. METHODS: 10 consecutive patients who underwent AMT were included. The indications were: group A, cases with persistent epithelial defect after corneal abscess (n = 1), radiation (n = 1), or chemical burn (n = 3); group B, cases with epithelial defect and severe stromal thinning and impending or recent perforation, due to chemical burn (two patients, three eyes) or corneal abscess (n = 2); group C, to promote corneal epithelium healing and prevent scarring after symblepharon surgery with extensive corneo-conjunctival adhesion (n = 1). Under sterile conditions amniotic membrane was prepared from a fresh placenta of a seronegative pregnant woman and stored at -70 degrees C. This technique involved the use of amniotic membrane to cover the entire cornea and perilimbal area in groups A and B, and the epithelial defect only in group C. RESULTS: The cornea healed satisfactorily in four of five patients in group A, but the epithelial defect recurred in one of these patients. After AMT three patients underwent limbal transplantation and one penetrating keratoplasty and cataract extraction. In group B amniotic membrane transplantation was not helpful, and all cases underwent an urgent tectonic corneal graft. Surgery successfully released the symblepharon, promoted epithelialisation and prevented adhesions in the case of group C. CONCLUSION: AMT was effective to promote corneal healing in patients with persistent epithelial defect, and appeared to be helpful after surgery to release corneo-conjunctival adhesion. Most cases required further surgery for visual and ocular surface rehabilitation. Amniotic membrane used as a patch was not effective to prevent tectonic corneal graft in cases with severe stromal thinning and impending or recent perforation.  (+info)

Allo-limbal transplantation in patients with limbal stem cell deficiency. (5/274)

AIM: To report the outcome of a series of patients with stem cell deficiency who underwent allo-limbal transplantation and to describe a technique for this procedure. METHODS: Six consecutive patients underwent allo-limbal stem cell transplantation. The primary diagnosis included alkali burn (n = 2), trachoma (n = 1), chronic rosacea blepharitis and kerato-conjunctivitis (n = 1), aniridia (n = 1), and Stevens-Johnson syndrome (n = 1). The limbal rim consisted of peripheral cornea and perilimbal sclera. FK-506 was used postoperatively for immunosuppression. RESULTS: The length of follow up ranged from 3 to 24 months (mean follow up 11.8 (SD 9.3) months). The outcome was considered satisfactory in five of six cases. The corneal surface was completely epithelialised within 2 weeks, and there was a substantial improvement in vision and symptoms. One patient had recurrent epithelial defects related to eyelid abnormalities. No side effects associated with systemic immunosuppression were noted. CONCLUSION: Allo-limbal transplantation, with systemic immunosuppression with FK-506 is useful in reconstruction of the ocular surface with improvement in vision in patients with severe stem cell deficiency.  (+info)

Medication-induced oesophageal injury leading to broncho-oesophageal fistula. (6/274)

Medication-induced oesophageal injury is one of the least recognised side-effects of oral medication and, in contrast to other oesophageal pathologies, is rarely considered in the differential diagnosis of chest pain. We describe a case of medication-induced oesophageal injury with a rare complication in which the diagnosis was not considered until the characteristic features were demonstrated at endoscopy.  (+info)

Effect of metalloproteinase inhibitor on corneal cytokine expression after alkali injury. (7/274)

PURPOSE: Interleukin (IL)-1alpha and IL-6 levels in the cornea are greatly elevated during the early stages after an alkali burn in mice. The authors investigated the effect of synthetic inhibitor of matrix metalloproteinase (SIMP) on the expression of inflammatory cytokines in alkali-burned murine corneas and evaluated the clinical appearance of the eyes. METHODS: After 0.5N NaOH-alkali burns to 400 corneas of ICR mice, 200 received 400 microg/ml of SIMP topically 4 times a day while 200 corneas were similarly treated with vehicle only. At days 4, 7 and 14 after injury, each cornea was assigned a clinical score for corneal opacity, corneal epithelial defect, hyphema and cataract. Extracts of injured corneas in each group were then assayed for cytokine production using ELISA systems for IL-1alpha, IL-1beta, IL-6 and tumor necrosis factor-alpha (TNF-alpha). RESULTS: The levels of IL-1alpha, IL-1beta and IL-6 were significantly lower in the SIMP-treated group than in the vehicle-treated group 7 days after the burn. However, levels of these cytokines were similar in the SIMP and non-SIMP groups at days 4 and 14. Levels of TNF-alpha did not differ between both groups at any postinjury time. In the SIMP-treated corneas, there was less opacification and hyphema formation and epithelial regeneration was faster. CONCLUSIONS: Topical application of SIMP in alkali-burned murine corneas reduced the expression of IL-1alpha, IL-1beta, and IL-6 and lessened the severity of the injury.  (+info)

Nitric oxide synthase-II is expressed in severe corneal alkali burns and inhibits neovascularization. (8/274)

PURPOSE: Inducible nitric oxide synthase (NOS-II) is expressed in many inflammatory conditions. The implication of nitric oxide (NO) in angiogenesis remains controversial. The role of NOS-II and its influence on angiogenesis in corneal neovascularization is unknown and was investigated in this study. METHODS: A mouse model of corneal neovascularization induced by chemical cauterization was used. NOS-II mRNA expression was analyzed by reverse transcriptase-polymerase chain reaction, and NOS-II protein was studied in situ by immunohistochemical analysis of the cornea. The influence of NOS-II on neovascularization was determined by comparison of vessel development in "normal" wild-type mice and mice with a targeted disruption of the NOS-II gene. RESULTS: NOS-II mRNA was induced to very high levels after corneal cauterization and remained upregulated throughout the disease. Migratory cells in the center of the cauterization area expressed NOS-II protein. The neovascular response in mice lacking the NOS-II gene was significantly stronger than in wild-type mice, and the difference increased over time. CONCLUSIONS: These data are the first evidence that NOS-II is expressed in this model of sterile corneal inflammation. NOS-II expression inhibited angiogenesis in severe corneal alkali burns.  (+info)

Chemical exposure to the eye may result in a chemical burn to the eye. Damage is usually limited to the front segment of the eye, including the cornea, the conjunctiva and occasionally the internal eye structures of the eye, including the lens. Burns that penetrate deeper into the anterior chamber are the most severe, often causing cataracts.. Note: The RMA SOP factor is limited to chemical burns where the chemical penetrates into the anterior chamber.. Chemical burns to the eye can be divided into three categories: alkali burns, acid burns, and irritants.. Alkali burns are the most dangerous. Alkalis (chemicals that have a high pH level) penetrate the surface of the eye and can cause severe injury to both the external structures like the cornea and the internal structures like the lens.. Common alkali substances contain the hydroxides of ammonia, lye, potassium hydroxide, magnesium, and lime. Substances that may contain these chemicals include fertilizers, cleaning products (ammonia), drain ...

A limitation to the use of biologic therapies is the risk of significant systemic adverse events. Local administration achieves lower systemic exposure to the drug and therefore is likely associated with lower rates of severe adverse events. The use of infliximab eye drops has been investigated as an alternative modality for local drug delivery. The administration of topical infliximab eye drops reduced corneal opacity, perforation, and eyelid fibrosis in a mouse model of corneal alkali burn,19 and improved tear volume, corneal surface regularity, and goblet cell density in a mouse model of dry eye.20 In rabbit models, the use of topical infliximab prevented corneal neovascularization21 and suppressed subconjunctival wound healing after trabeculectomy.22 On the other hand, cerebrovascular accidents are recognized complications of systemic anti-VEGF therapy23 while anti-TNF-α agents are associated with a risk of opportunistic infections, malignancies, infusion reactions, as well as cardiac and ...

We put the Hartz flea collars on 6 days ago onto 3 cats…wish Id known sooner! All 3, none of them related in any way, have the burns.
