[Peripartum management plan for patients with mental illnesses : Strategies to reduce the risk of postpartum relapse]

BACKGROUND

Transition to parenthood is challenging but for women with a history of recurrent psychiatric disorders becoming a mother has a number of additional issues. Women with a history of mood disorders or psychoses are at increased risk for exacerbation in the vulnerable postpartum period and fear the potential risk of medication during pregnancy for the unborn child as much as they fear a relapse. In these difficult situations women and their families seek advice and support from mental health providers and obstetricians.

METHODS AND RESULTS

Based on the treatment of 420 mentally ill women with a desire to have children and pregnancy and prospective documentation of 196 pregnancies over the last 10 years (2006-2016) the authors developed the Bonn concept of peripartum management (BKPM). The plan was designed to reduce the incidence and severity of postpartum relapses in women suffering from psychiatric disorders. Factors to be considered include antenatal and postpartum medication as well as reduction of stress and stimuli, sleep preservation, social support and help from the partner in caring for the baby. Of the 196 women in the BKPM only 4.6 % (n = 9) experienced a severe postpartum relapse with hospitalization. Additionally, the informed consent discussion with patient and partner as part of the peripartum management plan showed positive effects on how women and their families experienced autonomy and safety during pregnancy and postpartum.

DISCUSSION

Careful planning and monitoring with a structured perinatal management plan can reduce the risk of relapse in the perinatal period and thus support women with a history of mental disorder in the transition to motherhood. Therefore, the management concept employed in Bonn contributes to the major goal of current peripartum psychiatric care in developing effective prevention strategies for women at high risk.

Induced apoptosis of chondrocytes by Porphyromonas gingivalis as a possible pathway for cartilage loss in rheumatoid arthritis

The role of bacterial infections in the pathogenesis of rheumatoid arthritis (RA) has gained increasing interest. Patients with RA often exhibit periodontal disease, which is associated with pathogens like Porphyromonas gingivalis. The present study examines the direct effects of P. gingivalis on apoptosis of human chondrocytes (a feature of inflammatory joint diseases) as one can assume an interrelation of pathogenesis of RA and P. gingivalis infections. Primary chondrocytes were infected with P. gingivalis. Early apoptotic and dead cell analysis was performed using Annexin-V, 7AAD, and propidium iodide and examined by flow cytometry and fluorescence microscopy. Caspase activation and DNA fragmentation were determined by western blot analysis and TUNEL reaction. Flow cytometry and fluorescence microscopy demonstrated an increase of Annexin-V-positive early apoptotic chondrocytes after infection. Western blot showed upregulation of activated caspase-3 expression, and TUNEL reaction revealed considerable DNA fragmentation following infection. The data show that P. gingivalis promotes early and later stages of apoptosis of primary human chondrocytes, which might contribute to the joint damage seen in the pathogenesis of RA.

Effects of Porphyromonas gingivalis on cell cycle progression and apoptosis of primary human chondrocytes

BACKGROUND

It has been suggested that bacterial infections have a role in the pathogenesis of rheumatoid arthritis (RA). P gingivalis, a Gram-negative, anaerobic rod, is one of the major pathogens associated with periodontal disease.

OBJECTIVE

To examine P gingivalis infection and its effects on cell cycle progression and apoptosis of human articular chondrocytes.

METHODS

Primary human chondrocytes cultured in monolayers were challenged with P gingivalis. Infection and invasion of P gingivalis into chondrocytes was analysed by scanning electron microscopy, double immunofluorescence and by antibiotic protection and invasion assay. Cell cycle progression of infected chondrocytes was evaluated by flow cytometry. Also, cell apoptosis was visualised by terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling (TUNEL) of DNA strand breaks and by western blot analysis.

RESULTS

Data showed that P gingivalis could adhere and infect primary human chondrocytes. After chondrocyte infection, intracellular localisation of P gingivalis was noted. Flow cytometry analyses demonstrated affected cell cycle progression, with an increase of the G(1) phase and a significant decrease of the G(2) phase after infection. In addition, increased apoptosis of P gingivalis-infected chondrocytes was visualised by TUNEL assay and by upregulation of caspase-3 protein expression.

CONCLUSION

These data demonstrate that P gingivalis infects primary human chondrocytes and affects cellular responses, which might contribute to the tissue damage seen in the pathogenesis of rheumatoid arthritis.

Breast MR imaging screening in 192 women proved or suspected to be carriers of a breast cancer susceptibility gene: preliminary results

PURPOSE

To compare magnetic resonance (MR) imaging with conventional imaging in screening high-risk women.

MATERIALS AND METHODS

This prospective trial included 192 asymptomatic and six symptomatic women who, on the basis of personal or family history or genetic analysis, were suspected or proved to carry a breast cancer susceptibility gene.

RESULTS

Fifteen breast cancers were identified: nine in the 192 asymptomatic women (six in the first and three in the second screening round) and six in the symptomatic patients. Concerning the asymptomatic women, four of the nine breast cancers were detected and correctly classified with mammography and ultrasonography (US) combined; another two cancers were visible as well-circumscribed masses and were diagnosed as fibroadenomas. MR imaging allowed the correct classification and local staging of all nine cancers. In 105 asymptomatic women with validation of the 1st-year screening results, the sensitivities of mammography, US, and MR imaging were 33%, 33% (mammography and US combined, 44%), and 100%, respectively; the positive predictive values were 30%, 12%, and 64%, respectively.

CONCLUSION

The accuracy of MR imaging is significantly higher than that of conventional imaging in screening high-risk women. Difficulties can be caused by an atypical manifestation of hereditary breast cancers at both conventional and MR imaging and by contrast material enhancement associated with hormonal stimulation.

[Catamenial seizures--an analysis]

Catamenial seizures are defined as epileptic seizures occurring during distinct phases of the menstrual cycle (i.e., periovulatory, premenstrually and during menstruation). The cyclic changes of the gonadotropic hormones are thought to be the main cause of the seizures. This hypothesis is supported by results of animal experiments, which have shown oestrogens to increase neuronal excitability whereas progesterone lowered it. We investigated 21 women with epilepsy who reported a catamenial increase in seizure frequency. Only 24% of these women actually exhibited a catamenial manifestation in more than 75% of seizures. The incidence of catamenial seizures is reported in the literature to be between 10% and 72%. Catamenial seizures are treated with anticonvulsant drugs. However, when anticonvulsants have failed to suppress seizures, progesterone or progesterone-derivates have been administered with success. We treated 16 patients with a synthetic GnRH-analogue to suppress the hormonal release of gonadotropins. Four of the six patients with only catamenial seizure manifestations and no other seizures became seizure free. Ten patients had catamenial seizures as well as seizures not related to the menstrual cycle. A decrease in seizure frequency by more than 50% was achieved in 7 of these 10 patients.
