What is behind smoking among pharmacy students: a quantitative and qualitative study from Turkey

This study, performed in two phases, compared the smoking status of first- and last-year pharmacy students and identified underlying factors of smoking using both "quantitative" and "qualitative" research techniques. The quantitative phase was a cross-sectional study with 207 students (of these, 102 were first-year and 105 were last-year students). The mean age at which first-year students tried tobacco/tobacco products was 14.1 +/- 3.2 and for last-year students, 16.0 +/- 2.4. The students completed an 18-item questionnaire at the end of the spring semester in May 2004. Chi-square and t-test analyses were used for statistical comparisons. Furthermore, focus group discussion techniques were used to find out the underlying factors of smoking in the second phase.     

Does Fasciola hepatica infection modify the response of acute hepatitis C virus infection to IFN-α treatment？

Immunologic response to acute hepatitis C is mainly a Th1 response, whereas fasciolopsiasis is associated with a diverse T-cell response. Interferon-alpha has immunomodulatory effects and enhances Th1 immune response. Fasciola infection could theoretically interfere with the Th1 immune response, even when acquired after an initial response to interferon-alpha treatment for acute hepatitis C virus (HCV) infection. We report here the case of a male patient who acquired Fasciola hepatica infection after an initial response to IFN-alpha therapy with a favorable outcome.     

Multiple repeat caesarean section: is it safe?

OBJECTIVE: We aimed to evaluate the obstetric outcome of patients without obstetric risks, who had two or more previous caesarean sections (C/S) prior to the current pregnancy, which was managed by caesarean section in our obstetric department. METHODS: We studied the case notes of 602 women who had a repeat caesarean section in our unit between May 2002-June 2003. We then compared the two groups: (1) those who had two or more previous caesarean sections and (2) those who had only one previous caesarean section. RESULTS: In the study group, while dense intraperitoneal adhesions were present in 3.6% of the patients, they were not found in control group. This difference was statistically significant (P < 0.05). Uterine wound separation rate was 1.9% in the study group and none of the patients in control group had uterine wound separation, which was statistically significant also (P < 0.05). There was no statistically significant association between Apgar scores and number of previous caesarean sections. Postoperative complication rates did not differ between the two groups (P > 0.05). CONCLUSION: Patients without any obstetric risks, with two or more previous caesarean sections had significantly more dense adhesions and uterine wound separations in the current caesarean section compared to patients with one previous caesarean section. But, maternal and fetal mortality and morbidity in women who have two or more previous caesarean sections did not differ from the patients with one previous caesarean section.     

Association between homocysteinemia and renal function in patients with type 2 diabetes mellitus

Homocysteinemia is an independent risk factor for cardiovascular disease, but information on its association with type 2 diabetes and mild renal dysfunction is limited. Plasma total homocysteine (tHcy) concentration is partly determined by renal plasma clearance. Serum cystatin C (Cys C) concentration has been introduced as a marker of renal function, specifically as an indicator of glomerular filtration rate (GFR). The aim of this study was to explore the relationships among tHcy, creatinine clearance (Ccr), serum Cys C, and microalbuminuria in a population with type 2 diabetes. Fasting plasma tHcy, serum homocysteine-related vitamins (folate and vitamin B12), serum Cys C, serum creatinine, urine microalbumin, and creatinine clearance were determined in 75 type 2 diabetic patients and 40 healthy control subjects. The patients were assigned to two groups based on urinary albumin excretion (UAE): normoalbuminuric (NAU, UAE < 30 mg/24 hr, n = 35) and microalbuminuric (MAU, UAE 30-300 mg/24 hr, n = 40). Ccr was calculated using the Cockroft-Gault formula. Plasma Hcy levels were determined by HPLC with fluorescence detection and serum Cys C by automated particle enhanced immunoturbidimetry. Plasma tHcy levels were significantly higher in normoalbuminuric and microalbuminuric patients than in controls (10.64 +/- 0.53, 13.29 +/- 0.78, 6.91 +/- 0.37 mmol/L, respectively). Serum Cys C levels in microalbuminuric diabetics were higher than in normoalbuminurics and controls (1.36 +/- 0.06, 1.12 +/- 0.04, 1.10 +/- 0.06 mg/ L, respectively). Positive correlations were noted between tHcy and Cys C levels in normoalbuminuric and microalbuminuric diabetics (r = 0.72, r = 0.64, respectively). Homocysteine and creatinine concentrations were correlated in both diabetic groups (r = 0.89, r = 0.93, NAU and MAU, respectively). Elevated plasma total homocysteine concentrations in type 2 diabetics suggest an association between homocysteinemia and deterioration of renal function, evidenced by increased serum creatinine and Cys C, Ccr, and microalbuminuria. These findings implicate homocysteinemia in the relationship between diabetic nephropathy and cardiovascular complications of diabetes.     

Biomaterials in periodontal regenerative surgery: effects of cryopreserved bone, commercially available coral, demineralized freeze-dried dentin, and cementum on periodontal ligament fibroblasts and osteoblasts

The ultimate goal of periodontal therapy is to achieve successful periodontal regeneration. The effects of different biomaterials, allogenic and alloplastic, used in periodontal surgeries to achieve regeneration have been studied in vitro on periodontal ligament (PDL) cells and MC3T3-E1 cells. The materials tested included cryopreserved bone allograft (CBA), coralline hydroxyapatite (CH), demineralized freeze-dried dentin (DFDD), and cementum. CBA and CH revealed an increase in initial PDL cell attachment, whereas CH resulted in an increase in long-term PDL cell attachment. Mineral-like nodule formation was observed significantly higher in DFDD compared to other materials tested for osteoblasts. Based on the results of this in vitro study, we conclude that the materials used are all biocompatible with human PDL cells and osteoblasts, which have pivotal importance in periodontal regeneration.     

Natural history of clinical features in two brothers with acromesomelic dysplasia related to PRKG2

Acromesomelic dysplasias (AMD) are a group of skeletal dysplasia characterized by shortening of the middle and distal segments of the limbs. Recently, biallelic PRKG2 variants have been reported to cause a new type of AMD. We detected biallelic novel variant (c.1635-1G > C) in PRKG2 in two brothers with mild to severe short stature, short limbs, cubitus varus, and brachydactyly. Radiological examination showed platyspondyly with anterior beaking of the vertebral bodies, stubby long bones with metaphyseal flaring and moderate brachydactyly with cone-shaped epiphyses of the middle and proximal phalanges. Upper limb proportions of the older brother were clinically classified as rhizomelic, however radiologic findings supported acromesomelia, along with the elbow limitation. Annual follow-ups of the older brother from the age of 5 to 20 years revealed progression of short stature with age but platyspondyly and anterior beaking became less conspicuous. The younger brother showed milder short stature and less conspicuous disproportion of the limbs than those of the older brother; however, platyspondyly and anterior beaking were more prominent on the radiographs obtained at the same age. In conclusion, this report provides new insights into the natural history of AMD type PRKG2 confirming the intrafamilial heterogeneity.     

Life quality of patients who underwent breast reconstruction after prophylactic mastectomy: systematic review

Background

Prophylactic mastectomy is used to reduce the incidence of breast cancer in women with genetic predisposition and family history of breast cancer, and the rate of application is increased nowadays. Chronic pain, body image, and sexuality may negatively affect quality of life, while patients generally have increased quality of life and satisfaction after prophylactic mastectomy. The aim of this study is the evaluation of the results of the studies about quality of life of patients who underwent breast reconstruction after prophylactic mastectomy.

Methods

For the 1996–2016 literature, we searched the databases of Scopus, Science Direct, PubMed, EBSCO, Cochrane, Medline Complete, Ovid, Springer Link, Google Academic, Taylor & Francis, PsychINFO databases. For the gray literature, National Thesis Center and ULAKBIM databases were searched. Seven studies complying with the criteria were included in the review.

Results

Seven studies included in this study aimed to investigate the effect of prophylactic mastectomy on breast pain, numbness, sexuality and quality of life. When the studies were reviewed, we were found that the majority of the patients were satisfied with the results of the procedure, although the body image perception and pain/ movement/ perception and sexual problems were experienced after the breast surgery.

Conclusions

While overall satisfaction with cosmetic results was high, most women were not satisfied with the softness of the reconstructed breasts, and had problems with breast hardness, numbness and sex. Therefore, it is very important to inform the patients about the complications that may develop after the operation, while there is not enough data about the importance of informing the patients before the operation.
