Delirium is associated with increased mortality in the geriatric population

Objective: The aim of this study was to investigate the prevalence of delirium and its association with mortality rates in elderly inpatients.

Methods: The medical records of 1435 patients over 65 years old who were treated at a regional university hospital and were referred to the university’s Consultation and Liaison Psychiatry Clinic for psychological evaluation were retrospectively analyzed. Patients with and without a diagnosis of delirium were compared. The National Survival Database was used to determine mortality rates.

Results: The prevalence of delirium was 25.5%. The delirium group was older (p?p?p?Conclusions: Independent of all other factors, delirium is associated with higher mortality risk.     

Exploring the relationship between vitamin D and mania: correlations between serum vitamin D levels and disease activity

Background: Several studies suggest an association between hypovitaminosis D and mood disorders including major depressive disorder, seasonal affective disorder and premenstrual dysphoric disorder. On the other hand, there is not enough study about acute manic episode and hypovitaminosis D. This data insufficient zone led us to study on whether vitamin D deficiency is associated with acute manic episode and has an impact on disease activity

Methods: Thirty-one patients with bipolar disorder in remission, 26 patients with acute manic episode and 40 healthy controls with no major psychopathology were recruited in this study. Hamilton Depression Rating Scale (HAM-D), Young Mania Rating Scale (YMRS) and the Clinical Global Impression – Severety scale (CGI-S) were used to evaluate disease activity. Total vitamin D (D2?+?D3) values were measured.

Results: Patients in acute manic episode had significantly lower (p?=?.002) vitamin D serum concentrations than healthy controls (respectively 15.16?±?7.48 and 22.31?±?8.8) but remission group’s serum concentrations (18.40?±?7.30) did not differ significantly from healthy controls or acute manic episode patients (p?>?.05). We observed negative and moderate correlations between vitamin D levels and YMRS scores (r: ?0.641, p?r: ?0.559, p=?.003).

Conclusions: Our results contribute to the idea that vitamin D deficiency and acute manic episode may have interactions with many pathways. Future trials may investigate this association with longer follow up. We recommend that serum vitamin D levels should be measured in patients with bipolar disorder especially in long term care.     

Ulnar Styloid Fracture Accompanying Distal Radius Fracture Does Not Affect Hand Function,but What About Hand Dexterity?

Introduction  Hand dexterity is not addressed in patients with distal radius fracture (DRF) accompanied with ulnar styloid fracture (USF) in literature. This study aimed to determine whether an associated USF following a DRF has any effect on hand dexterity. Materials and Methods  Patients diagnosed with DRF were included in the study and were divided into two groups according to the USF presence (USF group and non-USF group). Pain, range of motion, Quick-DASH (Quick-Disabilities of the Arm, Shoulder, and Hand), handgrip and pinch strength, Purdue Pegboard test, and Jebsen Taylor Hand Function test were measured in the sixth month. Results  A total of 125 patients, 68 females (54.4%) and 57 males (45.6%) were included in the study. The mean age of the patients was 47.15 ± 13.41 (18–65) years. There were 60 patients (48%) in the USF group and 65 patients (52%) in the non-USF group. No significant difference was found in pain, range of motion, Quick-DASH and handgrip and pinch strength between the groups ( p > 0.05). The hand dexterity tests showed no statistically significant difference between the groups in the sixth month ( p > 0.05). Discussion  Hand function can be determined more accurately by assessing hand dexterity. In this study, it is emphasized that concomitant USF does not lead to poorer hand dexterity.     

Comparison of Low-Level Laser Therapy versus Ozone Therapy in the Treatment of Oral Lichen Planus

Background

The treatment options for oral lichen planus (OLP) are numerous and include topical and systemic agents. Intralesional and systemic corticosteroids are used; however, the therapeutic results are often disappointing.

Objective

To compare the influence of ozone, laser, and topical corticosteroid therapies in the treatment of OLP.

Methods

One hundred twenty adult patients with ≤3 cm atrophic-erosive biopsy-proven OLPs in the tongue or buccal mucosa were recruited into the study. They were randomly assigned, by preoperative envelope drawing, to be treated with low-level laser therapy (LLLT group), ozone therapy (ozonated group), and topical corticosteroid therapy (positive control group). A placebo treatment containing base ointment without the active corticosteroid component was administered to patients in the negative control group. Response rate scores were determined on the basis of changes in the appearance score and pain score of the lesions between baseline and after each treatment.

Results

The study subjects consisted of 56 male and 64 female OLP patients with a combined mean age of 42.6±8.3 years (range, 28~55 years). No statistically significant difference was detected in clinical severity among the groups. The sign scores decreased in almost all scoring groups; however, statistically significant improvement was found in the ozonated and corticosteroid-treated groups. Symptom improvement was achieved after treatment with LLLT, ozone, and corticosteroid (p<0.05). The efficacy indices were significantly higher in the ozonated and corticosteroid-treated groups.

Conclusion

Ozone and corticosteroid therapies were more effective than 808-nm LLLT in the treatment of OLP.     

Imiquimod and lymphatic field clearance: a new hypothesis based on a remote immune action on skin cancer

Basal cell carcinoma and actinic keratosis are frequent neoplasms. Topical treatments include the recently approved imiquimod cream. We describe here the case of a 68-year-old man with multiple actinic keratosis on the forehead, upper trunk and on the left cheek. In addition, an exulcerated basal cell carcinoma was observed. The patient was advised only to treat lesions on the forehead with imiquimod cream. This resulted in complete clearance of actinic keratosis within 6 weeks. At follow-up, a planned surgical excision of the basal cell carcinoma and actinic keratosis on the cheek was carried out. Histopathologically, both excision specimens no longer showed features of basal cell carcinoma or actinic keratosis, despite the fact that the imiquimod treatment was not applied to the cheek. Imiquimod cream is a topical immune response modifier, which has shown antiviral and anti-tumorous properties by inducing the production of cytokines as well as by stimulating dendritic cells and lymphocytes. Our observation supports the concept of lymphatic transport of immune cells and factors with subsequent immunological curing of tumours, not only in the treated area, but also those in the area between the imiquimod application site and the regional lymph nodes (the "lymphatic field clearance").     

Effects of ozone gas on skin flaps viability in rats: an experimental study

Background: The main purpose of this study was to assess the effects of ozone gas on the viability of flaps for reconstruction and to determine the optimum application method. The antioxidant, immunomodulatory, and reperfusion effects of ozone gas have been previously assessed, and successful results have been reported. However, only one study has investigated the effect of ozone gas on flap viability. In the present study, it was hypothesised that the antioxidant and reperfusion effects of ozone gas would enhance flap viability.

Methods: Forty female Wistar rats were randomly divided into four groups of 10 rats each. A cranial-based, 3?×?11?cm modified McFarlane flap including the panniculus carnosus was raised from the dorsum of a rat and re-sutured to its own bed using 3/0 sharp propylene. Group 1 (n?=?10): no pharmacological agent was used after the operation. Group 2 (n?=?10): vegetable (olive) oil group; vegetable-oil-impregnated gauze was used as a dressing for 7 days. Group 3 (n?=?10): Vegetable (olive) oil with ozone peroxide group; vegetable oil with ozone peroxide-impregnated gauze was used as a dressing for 7 days. Group 4 (n?=?10): Hemo-ozone therapy group; hemo-ozone therapy was applied rectally once every day for 7 days. All rats were sacrificed at the end of week 1 and assessed macroscopically and histopathologically.

Results: The proportion of substantive necrosis was less in group 4 than in the other three groups. Survival area ratios were better in groups 2 and 3 than in group 1; however, there was no significant difference between groups 2 and 3. No significant differences in the histopathological scores were observed among the groups.

Conclusion: Ozone gas enhanced flap viability. No differences in flap viability were observed between the vegetable oil and vegetable oil with ozone peroxide groups. The greatest benefit ratios were found in the hemo-ozone therapy group.

Thiol/disulfide homeostasis in predicting adverse perinatal outcomes at 24–28 weeks of pregnancy in gestational diabetes

Objective: The main aim of this study was to investigate thiol/disulfide homeostasis at 24–28 weeks of pregnancy and to evaluate whether it is predictive for adverse perinatal outcomes or not in gestational diabetes mellitus (GDM).

Methods: A total of 110 pregnant women at 24–28 weeks of pregnancy (74 GDM patients and 36 age- and BMI-matched healthy pregnant women) were enrolled in this prospective case–control study. Thiol/disulfide homeostasis was evaluated with a novel spectrophotometric method to determine if there is an association with adverse perinatal outcomes in GDM, by using logistic regression analysis.

Results: GDM patients, with decreased native thiol levels at 24–28 weeks (OR: 4.890, 95% CI: 1.355–5.764, p?=?0.015) and with higher pre-pregnancy BMI (OR: 1.280, 95% CI: 1.072–1.528, p?=?0.006), were found to be at increased risk of adverse perinatal outcomes in GDM. There were no statistically significant differences in thiol/disulfide homeostasis between diet- and insulin-treated GDM subgroups. Additionally, 1-h and 2-h glucose levels on 100?g OGTT were found to be predictive for the insulin need in achieving good glycemic control in GDM (OR: 1.022, 95% CI: 1.005–1.038, p?=?0.010 and OR: 1.019, 95% CI: 1.004–1.035, p?=?0.015).

Conclusions: GDM patients, with decreased native thiol levels at 24–28 weeks of pregnancy and with higher pre-pregnancy BMI, have an increased risk of possible adverse perinatal outcomes. Also, increased 1-h and 2-h glucose levels on 100?g OGTT can predict the need for insulin treatment for GDM.
