ABSTRACT
BACKGROUND: Clinical data relating to human papillomavirus (HPV) infection and p53 status in cervical cancer has been sparse and confusing. AIM: To evaluate high-risk HPV and expression of tumor suppressor protein p53 in squamous cell carcinoma of cervix and to assess response to mitomycin-C in neo-adjuvant chemotherapy. SETTING AND DESIGN: Teaching College Hospital; Gynecologic Oncology Unit and Department of Pathology. Prospective, randomized. MATERIALS AND METHODS: Expression of p53 protein was assessed, using immunohistochemistry with mouse monoclonal antibody in 30 consecutive patients undergoing radical hysterectomy or admitted for neo-adjuvant chemotherapy. Human papillomavirus DNA (HPV DNA) was assessed using hybrid capture II technology. Patients eligible for chemotherapy were randomized into vincristine, bleomycin and cisplatin (VBP) group and VBP with mitomycin C group. STATISTICAL ANALYSIS: Chi-square test, one-way ANOVA, Pearson's correlation; Mann-Whitney, McNemar and Fischer's exact tests were used for statistical analysis. RESULTS: All patients with cancer cervix were positive for high-risk HPV DNA having relative light units/cut off values ranging from 3.4-2389.21 (P value = 0.006). High viral load of high risk HPV DNA was seen in advanced stages (P = 0.05) and an association of viral load with tumor volume was also seen (r = 0.361, P = 0.05). Analysis of p53 protein in cervical carcinoma patient showed expression in 50% of cancer specimens (P value < 0.001). McNemar's and Fischer's exact test showed no change in p53 status post-chemotherapy; however 66% of stage II B patients in VBP-M group became operable. CONCLUSION: High-risk HPV was universally present in all cases of cancer cervix and viral load was associated with stage and tumor volume while p53 protein was expressed in 50% of cases suggesting deregulation. More studies using mitomycin-C in cervical cancer treatment protocols are needed.

Achondroplasia is a rare disorder occurring 1 in 1 5,000 to 1 in 40,000 live births. It is, however, the commonest cause of short-limbed dwarfism. It is a genetic disorder and inherited as an autosomal dominant trait but most cases (80%) are due to mutations of fibroblast growth factor receptor 3 (FGFR3). These individuals have normal mental and sexual development, and life span may be normal. Certain gynaecological problems like infertility, menorrhagia, dysmenorrhoea, leiomyomata and early menopause are more common in these patients. Information regarding obstetric behaviour in achondroplastic females is scarce in literature. However, problems such as pre-eclampsia, polyhydramnios, respiratory compromise, contracted pelvis necessitating lower section caesarean section, prematurity and foetal wastage, etc, have been reported. General anaesthesia is preferred to regional anaesthesia because of the spinal abnormalities. There is increased neonatal mortality due to hydrocephalus and thoracic cage abnormality. Such a patient is considered high risk in terms of anaesthesia and obstetric outcome and there is enough room for prenatal counselling and diagnosis. Here a case of achondroplasia with pregnancy is reported. The patient, an achondroplastic dwarf presented with 30 weeks pregnancy. She was prenatally screened with ultrasonography to rule out affection in baby. She had a caesarean section for contracted pelvis.

Severe folate deficiency in pregnancy may mimick HELLP syndrome as there are similar features in both. Proper diagnosis is important as far as the prognosis and management are concerned. Two cases of severe folate deficiency occuring in multigravid women mimicking HELLP syndrome are reported below with review of literature.

The airway functions in pregnancy have been widely studied but reports obtained from Western and Indian population show divergence. While the Indian populations show significant changes in total and timed vital capacity (FVC and FEV1), the Western counterparts dismiss such changes as insignificant. Our results show insignificant alteration in airway function and support the results reported for Western population.

A 2-year-old Manipuri girl had haemoptysis and a chest roentgenogram disclosed diffuse-infiltrates in the right lung. Microscopic examination of sputum and morning gastric aspirate showed numerous golden-brown, operculated ova, and microscopic examination of stool specimens confirmed these ova to be those of the lung fluke, Paragonimus westermani. She responded favourably to bithionol therapy and was asymptomatic and growing normally during follow up for one and half years.
