Case report--ocular rosacea.

Rosacea is an uncommon disease of the eye and facial skin. Ocular rosacea is often undiagnosed by the ophthalmologist especially when skin manifestations are not evident yet. Early diagnosis and treatment is important to decrease morbidity of this potentially blinding disease. A case of ocular rosacea in a 14-year-old Chinese girl is reported. Our patient presented with chronic non-specific keratoconjunctivitis. Only much later did the characteristic corneal and facial skin lesions appear. She responded to guttae prednisolone, oral and guttae tetracycline. This case illustrates the difficulty of early diagnosis when ocular manifestations precede those of the skin. We believe this is the first case of ocular rosacea reported in Singapore.

Melioidosis presenting with orbital cellulitis.

Melioidosis is known to present with many diverse manifestations but orbital cellulitis from melioidosis has never been described. We report a case of melioidosis in a 42-year-old diabetic male who presented with orbital cellulitis. He succumbed to recurrent empyema of the paranasal sinuses, rupture of an intracranial mycotic aneurysm and pulmonary empyema despite early antibiotic treatment.

Early discharge following major gynaecological surgery.

This prospective study was to assess the safety and acceptability to patients of early discharge after major gynaecological surgery. Selective patients who fulfilled certain criteria were offered early discharge after their operations. Forty patients were discharged within 72 hours. Fourteen of them had undergone abdominal hysterectomy, 5 with a mid-line incision; 13 had vaginal hysterectomy; 9 laparoscopy and laparotomy for ectopic pregnancy; 3 laparotomy for ovarian surgery and 1 a Manchester repair. The patients were discharged home on average 2.4 days after their operations. All were satisfied with their pain relief at home. There were 4 postdischarge complications. Two had superficial drip-site phlebitis, 1 a possible urinary tract infection and 1 a wound abscess. There was only 1 readmission 2 weeks post discharge for constipation. Thirty-one out of 40 (77.5%) of the patients had expressed that the home environment was more conducive to speedy recovery and 92.5% of the patients would choose early discharge again if given the option.

The residual adnexa syndrome.

The clinical profile of a group of 208 women who presented with residual adnexal disease subsequent to hysterectomy was studied retrospectively; 121 patients had the uterus removed vaginally and 87 per abdomen. The majority of the patients had the hysterectomy at less than 40 years of age, with a mean and median age of 33 years, and more than 60% presented with adnexal symptoms and signs within 5 years of hysterectomy. A detailed analysis of the symptoms and signs and pathology of the removed uterus in both groups was similar although as expected there was an associated finding of prolapse in a significant number of those treated by vaginal hysterectomy. There were significant delays both in the definitive diagnosis of subsequent residual adnexal disease and definitive treatment. The pathological changes in the removed residual adnexa were varied, but with a high incidence of inflammatory changes involving both the tube and ovary. This was particularly evident in those patients in whom the uterus had been removed by the vaginal route, suggesting that this may be related to the usual fixation or approximation of the conserved tube to the vaginal vault at the time of vaginal hysterectomy.

The effects of chronic maternal hypotension during pregnancy.

The relationship between chronic maternal hypotension and obstetric outcome was examined retrospectively in a group of 134 pregnant women and compared with a normotensive control group. The hypotensive women had significantly increased risks of delivery before the 38th week of gestation, lower birth-weight of babies for gestational age, and postpartum complications. In addition, the rates of preterm delivery before 37 weeks' gestation, birth-weight less than 2,500 g and significant meconium-staining of the amniotic fluid were higher in the hypotensive group, although these results did not reach statistical significance. These data support the need for a prospective study of the effects of chronic hypotension during pregnancy.
