Mucinous cystadenoma, serous cystadenoma and benign cystic teratoma of the ovary: clinico-pathologic differences observed in a Malaysian hospital.

A study of 207 benign ovarian tumors seen at the University Hospital, Kuala Lumpur between 1968 and 1975 was made to evaluate the clinical features that might be useful in the preoperative differentiation of mucinous cystadenoma, serous cystadenoma, and cystic teratoma of the ovary. This study indicated that the pertinent information included the mean age of the patient, the marital and menstrual status, and the estimated tumor size. The racial background was an additional factor in serous cystadenoma. Features like parity, the location of the tumor, and ABO blood group pattern were of no value in the preoperative differentiation.

Haemoglobin H disease and pregnancy in a Malaysian woman.

A case of haemoglobin H (HbH) disease associated with pregnancy is presented and discussed in the light of reports in the literature. The variable symptomatology is commented upon, although mild to moderate chronic haemolytic anaemia seems to be a constant feature. The roles of folic acid supplements and of splenectomy; the avoidance of oxidant drugs, and the mode of inheritance in HbH disease are briefly commented upon. Available reports indicate that HbH disease probably has no adverse effect on pregnancy. However, the association of the two conditions is uncommon, and reports are too few, therefore, to allow definite conclusions on the outcome in all instances.

Maternal and fetal outcome associated with hemoglobin E trait and hemoglobin E disease.

A study of 20 patients with hemoglobin E trait abnormality and 8 patients with hemoglobin E disease in pregnancy is presented. The hematologic abnormality in HbE hemoglobinopathy is mild though hemoglobin values are significantly lower than in HbA patients. Fetal wastage is no increased and the salvage rate is high (live births over 95 per cent). The mean birthweight of the baby in HbE patients is significantly lower than in HbA patients, but the incidence of prematurity is not significantly increased in HbE patients. Blood loss at delivery is not markedly affected by hemoglobin type. The incidences of postpartum hemorrhage, preeclampsia, and malaria are not significantly increased in HbE patients; the reason for the significant increase in incidence of abruptio placentae in HbE is not known. No maternal deaths or congenital fetal abnormalities were recorded. It is concluded that the course of pregnancy in HbE trait abnormality and HbE disease is relatively benign.
