A rare presentation of abortive epispadiac urethral duplication and vanishing midurethra

We report a 4-year-old boy with a hitherto undescribed case of abortive epispadiac duplication of the urethra presenting as a blind-ending penopubic sinus proximally and a mucosa-lined groove overlying the glanular corona distally but with absent midurethra. The patient was treated for cosmetic reasons with good results. A plausible embryological genesis of this defect is discussed.

Associated congenital anomalies in patients with anorectal malformations--a need for developing a uniform practical approach

Background/Purpose

The aim of this study was to compare the incidences of various associated anomalies among subjects with high and low anorectal malformation (ARM), study the coexistence of these anomalies, and compare their frequency with those quoted in the existing literature.

Methods

Ten years of data (from January 1993 through December 2002) on the 416 subjects from our center with anorectal malformations (ARM) were evaluated. The subjects with supra or translevator rectal pouch (radiologic or operative findings) were classified as high ARM and the rest as low ARM. The associated anomalies studied were vertebral, skeletal, renal, cardiac, vesicoureteric reflux (VUR), gastrointestinal, tracheoesophageal fistula, spinal, genital, and miscellaneous. For a detailed comparison, 4 subgroups were made: boys with high ARM, boys with low ARM, girls with high ARM, and girls with low ARM. Statistical methods were used for intergroup comparison.

Results

There were 68% male and 32% female subjects. Overall, 58% of subjects had high ARM (supralevator and translevator). Our attempt to compare the incidences of anomalies in our study population with those in other populations was defeated because of nonuniformity of classification and investigation of these anomalies in different studies. We found a frequent clubbing of anomalies affecting distantly developing anatomic regions in patients with ARM in many studies. The highest incidence of associated anomalies was found among boys with high ARM. The male subjects also had significantly more genital anomalies in association with low ARM and gastrointestinal tract anomalies in association with high ARM. On the other hand, girls had more urologic anomalies with high ARM and VUR with low ARM.

Conclusions

Except for a low incidence of spinal anomalies (8%) and of VUR (1.7%), the incidences of most associated anomalies in our study were comparable with those of the earlier studies. Additionally, the girls with high ARM were observed to have significantly more urologic anomalies compared with the boys with high ARM in contrast to the results of the earlier reports. The existence of anomalies in distantly developing anatomic regions in patients with ARM supports the possibility of a “generalized” insult during embryogenesis rather than a (“localized”) defect. It was observed that the boys with ARM are more likely to suffer morbidity because of frequent occurrence of multiple associated anomalies, and it may be worthwhile to evaluate of the role of sex chromosome in relation to ARM. The authors are also of the view that there is a need for more uniformity in classification of the anomalies and in their diagnostic approach because various reported studies have differed so widely on these aspects that any interstudy comparison is difficult or not feasible.     

Secondary intraocular lens (IOL) implantation: anterior chamber versus scleral fixation long-term comparative evaluation

PURPOSE: To compare the long-term efficacy of a secondarily implanted flexible angle supported anterior chamber (AC) intraocular lens (IOL) with sclerally fixated IOL as a secondary procedure in patients with aphakia. METHODS: Sixty patients with aphakia were recruited for this study. The patients were randomly divided into two groups: Group I patients underwent secondary implantation with AC IOL (Kelman Z type multiflex Domi classic AC IOL) and Group II patients underwent secondary implantation with scleral fixated IOL (Hanita lens with two eyelets). Postoperatively, the patients were followed up at 1 week, monthly for 6 months, and at twice yearly intervals for 5 years (mean follow-up was 3 years). RESULTS: Best-corrected visual acuity of 6/18 or better was achieved in 36.6% (11/30) of patients in Group I and 30% (9/30) of patients in Group II after a mean follow-up of 3 years. The complication rate was higher in Group II as compared to Group I. The authors encountered a total of 23 complications in the sclerally fixated group and 11 in the AC IOL group (p=0.004). Uveitis and ciliary tenderness were the most common complications in Groups I and II, respectively. CONCLUSIONS: For secondary implantation of IOL in aphakic patients, Kelman Z type multiflex Domi classic AC IOL is a better rehabilitation modality as compared to the scleral fixated Hanita IOL.     

Comparison between the role of intraoperative mitomycin C and doxorubicin in preventing the recurrence of primary pterygium

PURPOSE: The purpose of this study was to compare the role of intraoperative mitomycin C (MMC) and doxorubicin in preventing the recurrence of primary pterygium. MATERIALS AND METHODS: Fifty-six patients including 22 males and 34 females in the age range of 22-55 years (mean age 38.1 years +/- 10.7) having primary pterygium of progressive type were randomly divided into two groups. The first group of patients was treated with intraoperative MMC (0.02% for 3 min) and in the second group intraoperative doxorubicin (0.02% for 3 min) was used. The patients were regularly followed until 1 year postoperatively for examining visual acuity, wound condition, adverse events and recurrence of pterygium. RESULTS: The mean age of patients of MMC group was 37.4 +/- 11.0 years and of doxorubicin group was 38.8 +/- 10.8 years (difference statistically not significant). All these patients had pterygium on the medial side of cornea. The side effects experienced by our patients from the use of these agents were conjunctival hyperemia, conjunctival necrosis, corneal epithelial defect, subconjunctival hemorrhage, episcleritis, increased pain, foreign body sensation, lacrimation, irritation, diminution of vision and photophobia. Recurrence was seen in 4 patients of MMC group (14.3%) and 3 patients of doxorubicin group (10.7%) (difference statistically not significant; chi(2) = 0.16, p = 0.68). The recurrence of pterygium was not associated with age of patients, laterality of eye involved, amount of encroachment of pterygium over cornea, width of pterygium, preoperative complaints and postoperative adverse events. CONCLUSIONS: The two antimitotic agents, MMC and doxorubicin, when used intraoperatively along with primary pterygium excision, had a comparable role both in terms of adverse events and prevention of recurrence of pterygium.
