Perceptions on pregnancy and parenthood among program directors in pediatric dentistry.

PURPOSE: This cross-sectional study assessed the perceptions of pediatric dental residency program directors (PDs) regarding policies and attitudes on pregnancy and parenthood during residency training. METHODS: A 28-item electronic survey was administered to PDs of pediatric dental residencies in the United States. Statistical tests were performed. Variables were reported as counts (percentages) and compared using Fischer's exact test and chi-squared tests at a significance level of 0.05. RESULTS: Forty-two of the 97 PDs completed the survey for 43% response rate. Almost all programs had a formal maternal leave policy, but perceptions and policies varied regarding the effects of both pregnancy and parenthood on residents during training. Chi-square results compared if parenthood had a negative impact on the well-being a female trainee versus a male trainee had a p-value < .05. CONCLUSIONS: There appeared to be a lack of national uniformity regarding program policies on parental leave. Most PDs perceived having a child during residency had at least one negative effect on their female residents. Finally, PDs were likely to perceive parenthood to adversely impact the well-being and work of female trainees more so than their male counterparts.

Microbiome profiling in extremely acidic soils affected by hydrothermal fluids: the case of the Solfatara Crater (Campi Flegrei, southern Italy).

An integrated geochemical and microbiological investigation of soils from the Solfatara Crater (Campi Flegrei, southern Italy) demonstrated that interstitial soil gases dominated by CO2 and other typical hydrothermal gaseous species (e.g. H2S, CH4, ethane, benzene, alkenes and S-bearing organic compounds) influenced the composition of microbial communities. The relatively high concentrations of hydrothermal fluids permeating the soil produced acidic conditions and whitish deposits that characterize the Solfatara Crater floor. Archaea and Bacteria showed almost equal cell abundance (up to 3.2 × 107 and 4.2 × 107 cell/g, respectively) with relatively low levels of biodiversity and equitability in sites characterized by elevated temperatures (up to 70°C), very low pH values (up to 2.2) and reducing conditions. In these sites, high-throughput sequencing showed the marked selection of microorganisms, mainly affiliated with the genera Thermoplasma, Ferroplasma and Acidithiobacillus. A relatively high biodiversity and concomitant distinctive structure of the microbial community were observed in soils poorly affected by fumarolic emissions that were oxic and rich in organic matter.

Hypovitaminosis D Among Patients Admitted With Hip Fracture to a Level-1 Trauma Center in the Sunny Upper Egypt: Prevalence and Associated Correlates.

INTRODUCTION: Despite abundant sunshine, hypovitaminosis D is common in the Middle East. The aim of this study was to determine the prevalence of hypovitaminosis D and related correlates among patients with hip fracture in Assiut University Hospitals in Upper Egypt. MATERIALS AND METHODS: A cross-sectional study was carried out in 133 patients with hip fracture, aged 50 years and older, admitted to Trauma Unit of Assiut University Hospitals, from January through December 2014. Patients were selected by systematic random sampling. Serum 25-hydroxy vitamin D level was measured by enzyme-linked immunosorbent assay; bone mineral density (BMD) by dual-energy X-ray absorptiometry. Weight and height measurements were used for body mass index (BMI) calculation. RESULTS: Patients' median age was 70 years (range: 50-99); 51.9% were females. Osteoporosis (femoral neck T score: <-2.5 standard deviation) prevalence was 72.2%. Of all patients, 60.9% had vitamin D deficiency (<20 ng/mL); 15.8% reported vitamin D inadequacy (from 20 to 29 ng/mL) and vitamin D levels were normal in 23.3% (>30 ng/mL). According to univariate analysis, vitamin D deficiency was significantly associated with obesity (P = .012) and low T scores of the femoral neck (P = .001), L2 (P = .021), L3 (P = .031), L4 (P = .012), and the greater trochanter (P < .001). In a multivariable logistic regression model, high BMI and low BMD of the femoral neck and greater trochanter were associated with hypovitaminosis D. CONCLUSION: Prevalence of hypovitaminosis D is high among patients with hip fracture and associated with low BMD and high BMI. Increasing awareness about prevention as well as detection and treatment of vitamin D deficiency is recommended.

Neuropsychiatric evaluation of patients with brucellosis.

Brucellosis is a multisystem disease that may present with a broad spectrum of clinical manifestations. Neurobrucellosis is one of the complications. The objective of this study was to determine neuropsychiatric manifestations among patients with brucellosis. Twenty-seven consecutive patients with brucellosis (14 patients with manifest neurological manifestation and 13 patients without apparent neurological manifestation) were recruited from Assiut University hospital and compared with 50 healthy controls matched with respect to age, sex, and social economic and educational levels. They were subjected to systemic, meticulous neuropsychiatric evaluations, laboratory, radiological, neurophysiology, and psychometric assessment with Mini-Mental State Examination, Wechsler Memory Scale-Revised. and Hamilton Depression Rating. Overt or apparent neurological manifestation was recorded in 14 patients (51.85%) and 13 patients (48.15%) with brucellosis without apparent neuropsychiatric involvement. Central nervous system (CNS) involvement (vascular stroke, meningeoencephalitis, and dementia) was recorded in 9 patients (33.3%) and 6 patients (22.2%) had peripheral nervous sytem (PNS) involvement (polyneuropathy, radiculoapathy, and polyradiculoneuropathy). Depression was recorded in 7 (29.2%) patients; 3 patients (21.4%) of the neurobrucellosis group and 4 patients (30.8%) with brucellosis without neurological manifestations. Patients with brucellosis (neurobrucellosis and patients without neurological manifestations) reported highly significant impairment in some cognitive function measures (mental control, logical memory, visual reproduction) and higher scores on depressive symptoms compared with controls. Patients with a Brucella infection usually manifest central nervous system involvement. Clinicians, especially serving in endemic areas or serving patients coming from endemic areas, should consider the likelihood of neurobrucellosis in patients with unexplained neurological and psychiatric symptoms, and should perform the necessary tests, including cognitive function and depression tests.

Alopecia areata is not associated with Helicobacter pylori.

BACKGROUND: Alopecia areata (AA) is an immune-mediated form of hair loss that occurs in all ethnic groups, ages, and both sexes. Helicobacter pylori has been associated with many extra-digestive dermatological conditions. The causal relation between alopecia areata and Helicobacter pylori is discussed in this study. MATERIALS AND METHODS: We have screened for the presence of H. pylori in patients with AA, in order to determine any potential role in its patho-physiology. We have prospectively studied 31 patients with alopecia areata and 24 healthy volunteers of similar gender, for the presence of H. pylori stool antigen (HpSAg). RESULTS: Optical density values for H. pylori infection was positive in 18 of the 31 patients evaluated (58.1%), while in 13 patients, the values did not support H. pylori infection (41.9%). In the control group, 10 of the 24 (41.7%) had positive results. Within the group of alopecia areata, there was no significant difference between HpSAg positive and negative patients. CONCLUSIONS: The results have shown that a relation between Helicobacter pylori and alopecia areata is not supported. We advise that H. pylori detection need not to be included in the laboratory work up of alopecia areata.
