An outbreak of Aspergillus meningitis following spinal anaesthesia for caesarean section in Sri Lanka: a post-tsunami effect?

An outbreak of Aspergillus fumigatus meningitis occurred in 5 women following spinal anaesthesia, performed between 21 June and 17 July 2005 for caesarean section, in Colombo, Sri Lanka. The patients' median age was 27 years. Different teams in 2 maternity hospitals gave spinal anaesthesia. Mean incubation period was 11.2 days. Fever, headache and nuchal rigidity were common presentations. Remittent fever continued despite broad-spectrum intravenous antibiotics. Papilloedema, lateral rectus palsy, cerebral infarction and haemorrhage developed later. Three patients died. Cerebrospinal fluid pleocytosis with low glucose yielded negative PCR for fungi. Fungal cultures subsequently grew Aspergillus fumigatus. A post-mortem of the first patient confirmed Aspergillus meningitis, followed by treatment with amphotericin B and voriconazole, that saved the lives of others. Visual and hearing impairment in one and complete recovery in the other were observed a year after treatment. Examination of unused plastic syringes, needles, cannulae, and ampoules of anaesthetic agents confirmed that 43 syringes from three different manufactures were contaminated with Aspergillus fumigatus. The stores for drugs and devices of the Ministry of Health were examined and found to be full of tsunami donations, while regular procurements of the Ministry were kept in a poorly maintained humid warehouse. Inadequate space for tsunami donations was identified as the most plausible explanation for sub-optimal storage. Withdrawal and incineration of all unused syringes controlled the outbreak. The survival of those aggressively treated for Aspergillus meningitis suggests in hindsight that the availability of diagnostic tests and specific treatment, and early recognition of the outbreak could have saved the lives of victims who died. Early life-threatening side-effects and permanent long term sequelae of antifungal medication stress the need to be cautious with empirical treatment in immuno-competent low-risk individuals.

Pregnancy following renal transplantation in Sri Lanka.

OBJECTIVE: To assess the outcome and complications of pregnancy following renal transplantation in Sri Lanka. METHODS: Ten pregnancies following transplantation managed between January 1993 and July 1999 by the University Obstetrics and Gynaecology Unit, De Soysa Hospital for Women, Colombo were reviewed. RESULTS: Five women had planned pregnancy with an average duration from transplantation to conception of 2.3 (+/- 0.2) years; five had an unplanned pregnancy within 12 months of transplantation. All were treated with immunosuppressives, with none developing rejection. In the planned pregnancy group, 3 developed pregnancy induced hypertension and 3 impaired glucose tolerance. All delivered mature healthy babies with an average birth weight of 2.6 (+/- 0.3) kg. In the unplanned group, 1 developed cholestatic jaundice and delivered a growth retarded baby at 36 weeks. Another developed severe pulmonary oedema at 34 weeks (due to a past myocardial infarction) resulting in a fresh stillbirth. Two others has mid-trimester foetal deaths complicating severe diabetes mellitus. The conception at 3 months after transplantation developed diabetes mellitus and pregnancy induced hypertension, and delivered a live growth retarded baby. None had deterioration of renal function. CONCLUSION: Although a successful outcome is possible with stringent pre-pregnancy selection, maternal morbidity and foetal wastage can be high in those without.

Obstetric performance, perinatal outcome and risk of infection to the newborn in spontaneous and artificial rupture of membranes during labour.

OBJECTIVE: To compare the obstetric performance, perinatal outcome and risk of neonatal infection in labour following spontaneous (SROM) and artificial (AROM) rupture of membranes. DESIGN: Prospective, non-randomised, comparative study during a one-month period in 1995. The study was approved by the ethics committee of the Faculty of Medicine, University of Colombo. SETTING: University Obstetrics Unit at De Soysa Hospital for Women, Colombo. PATIENTS: 324 women who were in early established labour after 37 weeks of gestation. 151 of these had SROM and 173 AROM. The AROM and SROM groups among primigravidae and multigravidae were considered separately. RESULTS: Oxytocin use in multigravidae was significantly higher in the AROM group than in the SROM group (p < 0.001). The emergency caesarean section (LSCS) rate in primigravidae was significantly higher in the AROM group than the SROM group (p < 0.001). A significantly larger number of primigravid AROM women had abnormal fetal heart rate changes on auscultation (p < 0.05) and cardiotopographic (CTG) patterns (p < 0.001) when compared with primigravid SROM women. Choreoamnionitis and funisitis were commoner in the AROM group although the difference was not statistically significant. CONCLUSIONS: AROM appears to be associated with a higher chance of fetal distress particularly in primigravidae. Both AROM and SROM are associated with a potential risk of infection at intrauterine sites.

Econazole and clotrimazole in the treatment of vaginal candidiasis: a double blind comparative study.

OBJECTIVES: To compare the efficacy of treatment with econazole and clotrimazole in patients with vaginal candidiasis. DESIGN: A double blind study. Patients with vaginal candidiasis were randomly treated with vaginal depot preparations of econazole and clotrimazole. Efficacy after treatment by reduction of symptoms, a gynaecological examination and microbiological analysis of vaginal fluid. Adverse reactions were noted. SETTING: University gynaecological clinic at the de Soysa Hospital for Women, Colombo. PATIENTS: 102 patients microbiologically confirmed as having vaginal candidiasis. RESULTS: Two weeks after econazole treatment 19% still complained of a discharge and 7.5% had pruritus. The respective values for clotrimazole were 18% and 12%. The finding on gynaecological examination generally supported the reduction of symptoms. Microbiological assessment showed that 90.5% in the econazole group and 96% in the clotrimazole group became culture negative at two weeks after treatment. Adverse effects were similar in incidence and number for both treatment groups. Econazole was less acceptable to patients than clotrimazole. CONCLUSIONS: Econazole and clotrimazole are of equal efficacy for treatment of vaginal candidiasis. Econazole was less acceptable to patients.
