Spatial evaluation of prevalence, pattern and predictors of cervical cancer screening in India.

OBJECTIVE: To investigate the social determinants of cervical cancer screening and report the locations vulnerable to poor utilization of cervical cancer screening services. STUDY DESIGN: An ecological study with the data derived from fourth round of the National Family Health Survey conducted in India in the period 2015-2016. METHODS: The study focused on the percentage of women who have never undergone cervical cancer screening across 639 districts in India. Moran's I statistic was used to investigate the overall clustering of location. The Getis-Ord Gi* statistic was used for the detection of significant local clusters. Spatial error, spatial lag, spatial Durbin and spatial Durbin error models were compared, and the model with best fit was reported. ArcGIS, GeoDa and R software were used for the analysis. RESULTS: The existence of spatial autocorrelation (Moran's I = 0.61) necessitates the consideration of spatial component while studying the screening data. A significant clustering of districts with poor screening has been observed in the North-Central and North-Eastern regions of India. The geographic arrangement of the percentage of women who have undergone cervical cancer screening was associated with the percentage of women with poor wealth index (P < 0.001), not using a modern method of contraception (P < 0.001), residing in rural areas (P = 0.033) and never heard of sexually transmitted infection (P = 0.014). The range of percentage of women getting cervix screened for cancer was 0.5-68.4%, presenting the heterogeneity among the population elements. CONCLUSION: A higher risk of poor cervical cancer screening is observed in the districts where most of the women have poor wealth index, reside in urban area, have never heard of sexually transmitted infection and do not use a modern method of contraception.

Pharmacokinetics of lithium in patients treated with controlled release lithium formulations.

There has long been discussion as to the relative merits of the lithium formulations available in the UK. Two of these have been shown to exhibit similar pharmacokinetics in normal volunteers and both are now marketed as controlled release formulations. In this study the serum lithium profiles of these formulations were compared in patients at two centres during the first 4 h after the dose, and at 24 h. We were unable to show any significant difference between the formulations in respect of maximum serum lithium concentrations or the concentration at each time point.

Olanzapine-induced mania.

This report describes a case of manic symptoms induced by olanzapine in an 85-year-old female with a 3 year history of delusional disorder. She was treated in the past with trifluoperazine and risperidone. Symptoms were severe enough to require detention in hospital. Florid manic symptoms resolved two weeks after stopping olanzapine while only using 1 mg of haloperidol as required.

External-beam irradiation of carcinoma of the penis.

Twenty-four patients with biopsy-proved squamous-cell carcinoma of the penis underwent external-beam radiation therapy between 1966 and 1980. Fifteen were treated for the primary tumor and 9 for metastatic inguinal lymphadenopathy; no patient received prophylactic nodal irradiation. Doses ranged from 4,500 rad (45 Gy)/15 fractions/3 wk. to 6,400 rad (64 Gy)/32 fractions/6 1/2 wk. Seven out of 9 tumors in stage I, 2/3 in stage II, and 1/3 in stage IV were controlled for three years. Control of fixed, inoperable groin nodes was poor, and none of these patients survived beyond 1 1/2 years.

Leptomeningeal melanoma and Creutzfeldt-Jakob disease in a patient with chronic lymphocytic leukaemia.

A 78-year-old woman with known chronic lymphocytic leukaemia (CLL) was admitted to a psychiatric unit because of rapidly declining cognitive function. Clinical examination also revealed cerebellar signs and she later became akinetic and mute. She deteriorated and died of bronchopneumonia. The histology from the post-mortem confirmed the presence of CLL in the lymph nodes and she was also found to have diffuse leptomeningeal melanoma. In addition, there was extensive prion protein deposition in the cerebral cortex, but without significant spongiosis. The astrocytosis that was present appeared superficial only. Furthermore, prion protein appeared to be co-expressed with betaA4 in the form of plaques. The patient therefore had evidence of sporadic Creutzfeldt-Jakob disease (CJD) in addition to meningeal melanoma and CLL. This case further illustrates the importance of employing prion protein immunohistochemistry in suspected cases of CJD, especially where the histology is atypical.
