Severe, gestational, non-familial, non-genetic hypertriglyceridemia

Severe hypertriglyceridemia is a rare condition in pregnancy. All the cases of severe gestational hypertriglyceridemia that have been reported previously in the literature were caused by genetic mutations or familial hypertriglyceridemia secondary to lipoprotein lipase deficiency or apolipoprotein C-II deficiency. We report the first case of severe, non-genetic, non-familial, pregnancy-induced hypertriglyceridemia. The genetic underlying causes were excluded by molecular genetic investigation. The reported case was managed solely by strict dietary control. Hypertriglyceridemia was diagnosed incidentally during pregnancy, in this case, while taking a blood sample to check her hemoglobin level. Acute pancreatitis, which is a relatively common life threatening complication of this condition, was avoided. This report reviews the subtypes of hyperlipidemia, clinical picture, antenatal management and its effect on pregnancy and vice versa. It is important that the clinician has a clear understanding of the normal lipid profile during pregnancy, the clinical picture, the potential complications, available treatment options of hypertriglyceridemia particularly during pregnancy. The timing and route of delivery should be individualized.     

Prevalence and cytologic manifestations of human papilloma virus (HPV) types 6, 11, 16, 18, 31, 33, 35, 42, 43, 44, 45, 51, 52, and 56 among 500 consecutive women.

The prevalence and associated cytologic manifestations of cervical infection with human papillomavirus (HPV) types 6, 11, 16, 18, 31, 33, 35, 42, 43, 44, 45, 51, 52, and 56 were studied among 500 consecutive women attending the Harborview Medical Center Sexually Transmitted Diseases (STD) Clinic in Seattle, WA. Using radiolabeled-probes without prior amplification of DNA, HPV DNA was detected in cervical specimens from 120 (24%) of the women and was found to be more prevalent than Chlamydia trachomatis (13%), Neisseria gonorrhoeae (12%), or mucopurulent cervicitis (20%). High-risk HPV types 16 or 18 were present alone in 5% of the women; intermediate-risk types 31, 33, 35, 45, 51, 52, or 56 in 3%; and low-risk types 6, 11, 42, 43, and 44 in 5%. In an additional 8% HPV DNA was detected but could be characterized only as being type 6, 11, 16, 18, 31, 33, or 35. Each grouping of HPV types was equally associated with squamous intraepithelial lesions (SILs) of the cervix. In the absence of SIL and koilocytosis, the cytologic changes associated with HPV infection included frequent binucleation and variation in nuclear size and chromatin distribution. Parakeratosis and hyperkeratosis without nuclear atypia were not associated with HPV DNA. The natural history and clinical significance of these HPV-associated lesions remain to be defined.     

Cystosarcoma phyllodes: epidemiology, pathohistology, pathobiology, diagnosis, therapy, and survival

Cystosarcoma phyllodes is a very rare tumor which maybe difficult to diagnose clinically. The epidemiology and pathobiology are different from those of breast carcinoma. Risk factors, multicentricity, bilaterality, as associated with breast carcinoma, are not observed in patients with cystosarcoma phyllodes. Although the term "sarcoma" indicates a malignant tumor, only 10%-30% of cystosarcomas are histologically diagnosed as malignant; clinical diagnosis of malignancy does not exceed 10%. Axillary node involvement is rare, but hematogenous spread of cystosarcoma occurs into lung, pleura, bone, and liver. Clinically, cystosarcoma is a large (usually 3-5 cm in diameter) painless tumor with sudden growth acceleration especially during pregnancy. Cystosarcoma is usually circumscribed, containing firm and soft areas. The differential diagnosis has to include fibroadenoma, fibrocystic disease, mastitis, abscess, and medullary carcinoma. Neither clinical, mammographic or sonographic signs exist to predict a benign or malignant tumor. Therapy of cystosarcoma is not uniformly agreed upon. Radical, modified-radical, and simple mastectomy and tumorectomy are typical treatments; therapeutic results are the same for each treatment modality. For histologically diagnosed malignant cystosarcoma, the relative 5-year survival rate is about 80%. Clinically, malignant metastatic cystosarcoma is incurable; radiotherapy, endocrine treatment, and polychemotherapy are all ineffective. Because of the specific tumor pathobiology of cystosarcoma and its rarity, evaluation of treatment modalities and comparison of survival rates are difficult.     

Contraceptive knowledge and behavior of conventionalists, careerists, idealists, bouncers, desperadoes, and outsiders

The aim of the survey was to determine the contraceptive behavior and knowledge on contraceptive methods of adolescents. We defined six clusters according to personality, leisure activities, and sociodemographic characteristics: conventionalists, careerists, idealists, bouncers, desperadoes, and outsiders. 1010 Austrian adolescents aged 14–24 years participated in the survey. 96%–100% indicated that they were familiar with the condom and the contraceptive pill. The two most popular contraceptive methods cited were the condom (39%) and OC (34%). Whereas 40% of conventionalists reported that OC were their preferred method of contraception, 53% of idealists indicated that they preferred the condom. 66% of the desperadoes indicated that they considered the pill expensive. 85% of conventionalists and careerists believe that OC offer the best protection against pregnancy. Clusters with higher self-esteem and those with a higher educational level were more likely to believe that this method is unreliable. The results obtained indicate that outsiders, desperatoes, and bouncers show deficits in sex education; only careerists and idealists appeared to be better informed. Research on adolescent contraceptive behavior should drop the traditional stratifying criteria and appreciate the diversity of adolescent populations in order to be better able to classify adolescents according to their contraceptive attitudes.

Use of anti-infective agents during lactation: Part 2--Aminoglycosides, macrolides, quinolones, sulfonamides, trimethoprim, tetracyclines, chloramphenicol, clindamycin, and metronidazole.

Because many antibiotics are excreted into breast milk, it can be difficult for a practitioner to choose an antibiotic for a lactating patient that will have minimal risks to her nursing infant. This article is the second of a three-part series discussing the use of anti-infective agents during lactation. The authors review general information regarding use and common side effects for several classes of antibiotics. They also summarize information, including documented milk concentrations, milk-to-plasma ratios, and other pharmacokinetic properties, in a table that can help practitioners choose antibiotics that may be considered safe to use in the lactating mother.     

Preeclampsia,Placenta, Oxidative Stress,and PMCA

Objective: The aim of this study is to summarize the reported evidence on the possible relationship between preeclampsia, placenta, oxidative stress and plasma membrane Ca-ATPase (PMCA) activity, responsible for fine control of intracellular calcium concentration. Methods: Literature search was conducted in MEDLINE/PubMed and several unpublished results from our laboratory were included. Results: Lipid peroxidation in placental and red blood cell plasma membranes during preeclampsia and a concomitant diminution of their PMCA activity are described. Conclusions: Uteroplacental hypoperfusion raises lipid peroxidation by-products in the blood plasma that could alter structure and functionality of the cell membranes of the endothelium and several tissues.     

Seroprevalence of other antibodies (herpes, CMV, rubella, varicella, hepatitis B and C, syphilis, chlamydia, mumps, toxoplasmosis) in HIV-positive patients

We attempted to determine the seropositivity of HIV-positive patients to other antibodies (herpes, CMV, rubella, varicella, hepatitis B, hepatitis C, syphilis, chlamydia, mumps, toxoplasmosis). The study was carried out at the Prenatal Diagnosis and Therapy Centre of a Tertiary Hospital in Lagos, Nigeria. A total of 70 patients (50 females and 20 males) attending the centre between June 1997 and December 2005 who were screened and found to be HIV-seropositive were further screened for herpes simplex IgG/IgM, CMV IgG/IgM, rubella IgG/IgM, varicella IgG/IgM, mumps IgG/IgM, toxoplasmosis IgG/IgM, chlamydia IgG/IgM, hepatitis B and hepatitis C IgG/IgM using ELISA kits and syphilis (THPA) using the HAE method. Our study showed that a large number of HIV-positive patients are carriers of other antibodies and should be screened for them before therapy.     

Sperm viral infection and male infertility: focus on HBV,HCV, HIV,HPV, HSV,HCMV, and AAV

Chronic viral infections can infect sperm and are considered a risk factor in male infertility. Recent studies have shown that the presence of HIV, HBV or HCV in semen impairs sperm parameters, DNA integrity, and in particular reduces forward motility. In contrast, very little is known about semen infection with human papillomaviruses (HPV), herpesviruses (HSV), cytomegalovirus (HCMV), and adeno-associated virus (AAV). At present, EU directives for the viral screening of couples undergoing assisted reproduction techniques require only the evaluation of HIV, HBV, and HCV. However, growing evidence suggests that HPV, HSV, and HCMV might play a major role in male infertility and it has been demonstrated that HPV semen infection has a negative influence on sperm parameters, fertilization, and the abortion rate. Besides the risk of horizontal or vertical transmission, the negative impact of any viral sperm infection on male reproductive function seems to be dramatic. In addition, treatment with antiviral and antiretroviral therapies may further affect sperm parameters. In this review we attempted to focus on the interactions between defined sperm viral infections and their association with male fertility disorders. All viruses considered in this article have a potentially negative effect on male reproductive function and dangerous infections can be transmitted to partners and newborns. In light of this evidence, we suggest performing targeted sperm washing procedures for each sperm infection and to strongly consider screening male patients seeking fertility for HPV, HSV, and HCMV, both to avoid viral transmission and to improve assisted or even spontaneous fertility outcome.     

A conversation with Dr Anne McLaren,DBE, DPhil,FRS, FRCOG

Anne McLaren is one of the world's foremost developmental biologists; a leader in elucidating the principles of early mammalian development whose research has underpinned advances in reproductive medicine and the treatment of infertility. After undergraduate and postgraduate studies at Oxford University and postdoctoral work in London, she was for 15 years at the Institute of Animal Genetics in Edinburgh followed by 18 years as Director of the MRC Mammalian Development Unit in London. She is currently a Group Leader at the Wellcome Trust/Cancer Research UK Gurdon Institute in Cambridge. She was elected a Fellow of the Royal Society in 1975 and became the first woman to hold office in that Society – as Foreign Secretary, from 1991–1996. Dr McLaren played a pivotal role in the creation of the UK Human Fertilisation and Embryology Authority. She was a member of the Warnock Committee, served on the Voluntary (later Interim) Licensing Authority and was a key member of the HFEA from its establishment until the end of 2001. She chaired the Scientific and Technical Advisory Group of WHO's Human Reproduction Programme and is President of the Association of Women in Science and Engineering. She is a member of the European Group on Ethics that advises the European Commission on social and ethical implications of new technologies. In 2002, she was awarded (jointly with A. K. Tarkowski) the Japan Prize for Developmental Biology. She continues to have one of the sharpest minds in the business; for her, science has been not only a joy but an intellectual adventure of the highest order. She is interviewed here by Editorial Board Member Jane Denton.     

Turn, turn, turn

Twenty years have passed since the publication in these pages of the oft-quoted editorial "The leader of the band is tired." At that time, the passing was mourned of the era of laparotomy for reconstructive pelvic surgery and the arrival of the laparoscope was heralded. Another transformation has occurred. Just as laparoscopy replaced laparotomy, all traditional treatments for infertility are being rendered obsolete by advanced reproductive technologies.
