Surgical management of lacrimal punctal cauterization in chronic GVHD-related dry eye with recurrent punctal plug extrusion.

We investigated the efficacy of lacrimal punctal occlusion surgery with a cautery device in patients with chronic GVHD (cGVHD)-related dry eye, with recanalization of puncta and recurrent punctal plug extrusion. A total of 23 puncta from 14 eyes of 10 patients with chronic GVHD (cGVHD)-related dry eye underwent punctual thermal cauterization with a high-temperature disposable cautery device. All patients were refractory to conventional treatment, including artificial tear eye drops, autologous serum eye drops and vitamin A eye drops, and had a history of recanalization and recurrent punctal plug extrusion. The effect of lacrimal punctal cauterization by thermal cautery device was evaluated by changes in subjective symptom scores, corrected distance visual acuity, Schirmer's test values, fluorescein staining scores, rose bengal staining scores, and tear-film break-up time before and 3 months after the surgery. Subjective symptom scores, Schirmer's test values, fluorescein and rose bengal scores, and tear-film break-up time improved significantly 3 months after the surgery. Recanalization of puncta was not observed in all the cases (0 of 14 eyes, 0%). Lacrimal punctal cauterization was effective with no recanalization and significant improvements in subjective symptoms and the ocular surface environment in cGVHD-related dry eye patients who had been refractory to conventional treatments.

Donor-recipient gender difference affects severity of dry eye after hematopoietic stem cell transplantation.

PURPOSE: To determine whether the incidence rate and severity of dry eye after hematopoietic stem cell transplantation varies with donor vs recipient gender. METHODS: We limited this study to patients received bone marrow transplantation (BMT). In all, 172 patients received BMT at Keio University School of Medicine between January 2000 and May 2007. Of them, 136 recipients who survived at least 70 days were studied prospectively. We classified the 136 patients according to the gender of the donor and the recipient (group I: female to female; group II: male to male; group III: male to female; group IV: female to male). The incidence and severity of chronic graft-vs-host disease-associated dry eye were determined for each group. The donor gender was masked when we assessed dry eye and calculate the incidence. RESULTS: The incidence of dry eye was 47.4% for group I, 37.5% for group II, 58.6% for group III, and 42.9% for group IV. The percentage of patients with severe dry eye was 44.4, 50.0, 35.3, and 77.8% respectively. There was a significant difference between the percent severe dry eye/total dry eye incidences in groups III and IV (P=0.0375) (odds ratio, 7.6; 95% confidence interval, 1.00-101.01). CONCLUSIONS: Close attention must be paid to the development of dry eye in cases of female to male BMTs, because the ratio of severe/total dry eye is more common in cases of female to male BMTs than in other gender combination.

Baseline profiles of ocular surface and tear dynamics after allogeneic hematopoietic stem cell transplantation in patients with or without chronic GVHD-related dry eye.

We evaluated ocular surface alterations in allogeneic hematopoietic stem cell transplantation (HSCT) recipients with or without chronic GVHD-related dry eye in a prospective study. Fifty eyes of 25 post-HSCT patients and 28 eyes of 14 age-matched healthy controls were included. Meibomian gland (MG) obstruction, tear evaporation rate, corneal sensitivity (CS), Schirmer test-I, tear break-up time (BUT) and ocular surface vital staining were examined. Conjunctival impression and brush cytology specimens were collected to evaluate the goblet cell density (GCD) and the inflammatory cell numbers. Obvious MG obstruction, decreased CS and enhanced tear evaporation rate were found in post-HSCT patients compared with normal controls. In addition, decreased conjunctival GCD, increased conjunctival squamous metaplasia and inflammatory cells were noted in cGVHD-related dry eyes compared with normal controls and post-HSCT without dry eye subjects. Furthermore, the conjunctival inflammatory cells were significantly higher in severe dry eyes compared with mild dry eyes (P=0.03). We found comprehensive ocular surface alteration in post-HSCT patients, regardless of whether they had cGVHD-related dry eye or not. The results suggest that the extent of inflammatory process seems to have a pivotal role in the outcome of the cGVHD-related dry eye.

Topical tranilast for treatment of the early stage of mild dry eye associated with chronic GVHD.

Fibrosis and excessive extracellular matrix production are characteristic features of lacrimal gland chronic GVHD (cGVHD). Tranilast (n-[3,4-anthoranilic acid]), used for fibrotic skin disease, inhibits transforming growth factor-beta-induced matrix production. We conducted a non-randomized study comparing 8 patients (five men, three women; median age, 47 years) given topical tranilast with 10 patients (three men, seven women; median age, 37 years) receiving therapy with topical artificial tears, sodium hyaluronate and vitamin A for mild ocular cGVHD. The tranilast group instilled topical tranilast and artificial tears q.i.d., beginning the day of dry eye diagnosis. The ocular surface and tear dynamics of each patient were evaluated before hematopoietic stem cell transplant, at the onset of dry eye and after 3 months of treatment. At 3 months, the scores of the Rose Bengal test and Schirmer test with nasal stimulation had significantly improved in the tranilast group compared with that in the control group (P<0.05). Furthermore, although five control patients (50%) developed severe dry eye within the treatment period, only one tranilast-treated patient (12.5%) did; the rest still had mild dry eye (P<0.05). These results suggest the hypothesis that topical tranilast may effectively retard the progression of mild dry eye associated with cGVHD.

Fibroma of the urinary bladder: a light and ultrastructural study of a case with review of the literature in Japan.

A hard fibroma of the urinary bladder was found in an autopsy case of a 69 year-old female. The tumor, 10x9x6 cm, occurred in the superior wall of the bladder. Ultrastructurally, the principal cells of the tumor were myofibroblasts. Fibroblasts and fibrocytes were also present. Including our case, the number of reported cases of pure fibroma of the urinary bladder in Japan is 12. These are reviewed briefly.
