If perforated, pyometra may cause peritonitis and lethal septic shock. Not only gynecologists but also emergency physicians should be aware of this possibility. Moreover, patient education is necessary. In patients with cardiopulmonary arrest, diagnostic abdominal paracentesis should be performed when the sole imaging finding is ascites. Improving outcomes in patients with difficult-to-diagnose pyometra with cardiopulmonary arrest by implementing damage control strategies before hysterectomy is possible.

Despite the availability of comprehensive emergency obstetric care at Dodoma Regional Referral Hospital, deaths due to obstetric haemorrhage are still high. This study was carried out to analyse the circumstances that had caused these deaths.

A retrospective review of all files of women who had died of obstetric haemorrhage from January 2018 to December 2019 was made.

A total of 18,296 women gave birth at DRRH; out of these, 61 died of pregnancy-related complications of the deceased while 23 (38%) died of haemorrhage, with many of them 10 (44%) between the age of 30 and 34. Many were grand multiparous women 8 (35%) and almost half of them (11 (48%)) had stayed at DRRH for less than 24 hours. More than half (12 (52%)) had delivered by caesarean section followed by laparotomy due to ruptured uterus (8 (35%)). The leading contributing factors to the deaths of these women were late referral (6 (26%)), delays in managing postpartum haemorrhage due to uterine atony (4 (17%)), inadequate preparations in patienemorrhage is high at Dodoma Regional Referral Hospital where more than one-third of women died between 2018 and 2019. Almost all of these deaths were avoidable. The leading contributing factors were late referral from other health facilities, inadequate skills in managing PPH due to uterine atony, delays in performing caesarean section at DRRH, and inadequate preparation for managing PPH in patients with abruptio placentae and IUFD which are risk factors for the condition. There is a need of conducting supportive supervision, mentorship, and other modes of teaching programmes on the management of obstetric haemorrhage to health care workers of referring facilities as well as those at DRRH. IBMX Monitoring of labour by using partograph and identifying pregnant women at risk should also be emphasized in order to avoid uterine rupture.

Internal bleaching is a choice of treatment in discolored endodontically treated teeth. Cervical root resorption is one of the important complications of this treatment. A suggested procedure to prevent this type of resorption is using a coronal barrier under the bleaching materials. The aim of the study was to compare the microleakage of mineral trioxide aggregate (MTA), calcium-enriched mixture (CEM) cement, and Biodentine.

In this in vitro study, a total of 60 single canal incisors were included. They were randomly divided into three experimental groups (

 = 16), one positive control group (

 = 6), and one negative control group (

 = 6). Coronal portion of the canals in the experimental groups was sealed with 3 mm of MTA, CEM cement, or Biodentine as a coronal barrier. After 3 days, specimens were bleached. A fresh

suspension was added to the samples. The culture tubes were observed for 45 days, and the daily turbidity was recorded. Statistical analysis was accomplished by the Kaplan-Meier test and SPSS 22.

All positive samples showed turbidity, whereas none of the negative samples allowed bacterial leakage. Results showed no significant difference between MTA, CEM cement, and Biodentine groups. (

value = 0.304, 0.695, and 0.217). The bacterial microleakage for the two groups also did not show significant differences.

CEM cement and Biodentine showed promising results as coronal plug, and clinical studies are needed to test these materials with MTA for avoiding microleakage in internal bleaching treatment.

However, little is known about the synergic effects of EtOH abuse and estrogen deficiency on alveolar bone loss in women. The present study evaluated the effects of EtOH chronic exposure and ovariectomy on the alveolar bone loss in female rats. For this, 40 female Wistar rats were randomly divided into 4 groups control, EtOH exposure, ovariectomy (OVX), and OVX plus EtOH exposure. Initially, half of the animals were ovariectomized at 75 days of age. After that, the groups received distilled water or EtOH 6.5 g/kg/day (20% w/v) for 55 days via gavage. Thereafter, animals were sacrificed and the mandibles were collected, dissected, and separated into hemimandibles. Alveolar bone loss was evaluated by measuring the distance between the cementoenamel junction and the alveolar bone crest through a stereomicroscope in 3 different anatomical regions of the tissue. One-way ANOVA and post hoc Tukey were used to compare groups (p less then 0.05). The results showed that the ovariectomy and EtOH exposure per se were able to induce alveolar bone loss, and their association did intensify significantly the effect. Therefore, OVX associated with heavy EtOH exposure increase the spontaneous alveolar bone loss in rats.

To assess the level of dental radiographers' compliance with infection control measures and to evaluate the factors affecting their compliance.

The study included 175 dental radiographers. Compliance with infection control was evaluated with a self-administered questionnaire consisting of 33 questions related to vaccination, hand hygiene (HH), personal protective equipment (PPE), disinfection and sterilization, and use of surface barriers. Pearson's chi-square test was used to compare compliance between subgroups of radiographers.

64.6% of participants were females, and 62.9% was younger than 30 years. 13.0% of the sample population had >10 years of experience and 28.0% take radiographs for >20 patients/day. 66.9% of participants wash their hands before/after taking radiographs. 26.3% of participants had vaccination against hepatitis B, tetanus, and tuberculosis. 12.6% fully use PPE, 10.9% perform complete disinfection and sterilization, and 16.0% apply all kinds of surfaces barriers. Vaccination was significantly affected by age, gender, and practice type.
