Retrospective Comparative Study

BACKGROUND: The recurrence rate after successful transnasal adenomectomy in Cushings disease (CD) can reach 47%. We have previously shown that patients with ACTH levels less than 7 pg/ml recurred over 3 years 4.5 times less often than patients with higher levels of ACTH, patients with cortisol levels below 123 nmol/l in 3.4 times less than at higher values of this hormone, however, these indicators are dissociated in 41% of cases, so it is not possible use them for prediction separately. AIM: To develop a method for managing patients after successful transnasal adenomectomy depending on prognosis. METHODS: A monocenter retrospective comparative study included 349 patients (52 men, 297 women) with a confirmed diagnosis of CD, who underwent effective endoscopic transsphenoidal adenomectomy in 20072014. Various combinations of postoperative morning levels of ACTH and cortisol were analyzed. RESULTS: Based on the developed forecasting methods and their best characteristics, the following rules were formulated. If postoperative morning ACTH is less than 7 pg/ml and/or postoperative morning cortisol is less than 123 nmol/l, then the patient will remain in remission for 1 year with probability of 99% (95% CI 97%100%) and for 3 years with probability of 86% (95% CI 80%91%). CONCLUSION: The rules for predicting remission for 1 and 3 years for patients after neurosurgical treatment for CD are proposed. These rules are based on combinations of ACTH and cortisol levels.

Background: Verruca is one of the common dermatopathologies which has multiple therapeutic options but with variable success rates, refractory cases and high recurrence rates. Nowadays, treatment with intralesional injections has gained recognition due to its effectiveness in clearing verrucae. These act by stimulating the cell-mediated immunity. Out of scores of options available for intralesional therapeutics, Vitamin D3 appears to be more promising but least evaluated. Therefore, we planned to evaluate the efficacy of intralesional Vitamin D3 in various types of cutaneous verrucae. Simultaneously the results were compared with intralesional bleomycin, also. Methods: A total of 200 patients of cutaneous verrucae with varying size and duration were included in the experimental randomized comparative study. We divided them into two groups. Group A, comprising of 100 patients, received 0.2-0.5 ml intralesional Vitamin D3 (600,000 IU, 15mg/ml) and Group B, also of hundred subjects, received intralesional Bleomycin (1 mg/ml) into the base of verrucae. A maximum of 5 verrucae were injected per session at 3 weeks interval until resolution or for a maximum of 4 sessions. Patients were followed up for 6 months after the last injection to assess the clearance status and detect any recurrence. Results: In Group A (Vitamin D3), 'Complete response', 'Partial response' and 'No response' were observed in 85.07%, 6.74% and 8.17% respectively after 4 sessions. Recurrence rate was 0.81% after 6 months. In Group B (Bleomycin), 'Complete response', 'Partial response' and 'No response' were found in 77.99%, 10.47% and 11.53% in the series. Recurrence rate was 1.71%, comparatively higher in group B. Conclusion: The efficacy of intralesional Vitamin D3 was found significantly higher as compared to intralesional Bleomycin in the treatment of cutaneous verrucae with less recurrence rates. Vitamin D3 has an additional advantage of cost-effective treatment over Bleomycin. We purpose its use, as a primary mode of treatment in various types of cutaneous verrucae.

Abstract Background Hypothalamic-pituitary-adrenal (HPA)-axis dysfunction has been associated with a variety of mental health and cardio-metabolic disorders. While causal models of HPA-axis dysregulation have been largely focused on either pre-existing health conditions or psychosocial stress factors, recent evidence suggests a possible role for central nervous system activation via air pollutants, such as nitrogen dioxide (NO2), ozone (O3) and particulate matter (PM). Therefore, in an observational study of Latino youth, we investigated if monthly ambient NO2, O3, and PM with aerodynamic diameter ≤ 2.5 (PM2.5) exposure were associated with morning serum cortisol levels. Methods In this cross-sectional study, morning serum cortisol level was assessed after a supervised overnight fast in 203 overweight and obese Latino children and adolescents (female/male: 88/115; mean age: 11.1 ± 1.7 years; pre-pubertal/pubertal/post-pubertal: 85/101/17; BMI z-score: 2.1 ± 0.4). Cumulative concentrations of NO2, O3 and PM2.5 were spatially interpolated at the residential addresses based on measurements from community monitors up to 12 months prior to testing. Single and multi-pollutant linear effects models were used to test the cumulative monthly lag effects of NO2, O3, and PM2.5 on morning serum cortisol levels after adjusting for age, sex, seasonality, social position, pubertal status, and body fat percent by DEXA. Results Single and multi-pollutant models showed that higher O3 exposure (derived from maximum 8-h exposure windows) in the prior 1–7 months was associated with higher serum morning cortisol (p < 0.05) and longer term PM2.5 exposure (4–10 months) was associated with lower serum morning cortisol levels (p < 0.05). Stratification by pubertal status showed associations in pre-pubertal children compared to pubertal and post-pubertal children. Single, but not multi-pollutant, models showed that higher NO2 over the 4–10 month exposure period associated with lower morning serum cortisol (p < 0.05). Conclusions Chronic ambient NO2, O3 and PM2.5 differentially associate with HPA-axis dysfunction, a mechanism that may serve as an explanatory pathway in the relationship between ambient air pollution and metabolic health of youth living in polluted urban environments. Further research that uncovers how ambient air pollutants may differentially contribute to HPA-axis dysfunction are warranted.

Minimally Invasive Reduction

Background Several minimally invasive techniques were developed for management of intraarticular calcaneal fractures. This study aimed to compare the functional and radiological outcomes of 2 minimally invasive reduction and fixation techniques using cannulated screws or Kirschner wires (K-wires) for fixation. Methods This study was a retrospective comparative review of patients with displaced intraarticular calcaneal fractures, who were treated with cannulated screws or K-wires techniques. Clinical and radiological data were collected and compared between both groups. Functional outcomes and patient satisfaction using the Maryland Foot Score (MFS) and the visual analogue scale (VAS) of pain, in addition to the complications, were compared between both groups. Results In total, 70 patients were included in the study: 34 in the cannulated screws group, with a mean age of 35.2 ± 4 years, and 36 in the K-wires groups, with a mean age of 33.4 ± 3 years. The operative time was shorter in the K-wires group (40.5 ± 5.6 minutes) compared to the cannulated screw group (49.5 ± 4.5 minutes), P < .001. There were no statistically significant differences between both groups regarding the radiological parameters, including Bohler’s angle, angle of Gissane, calcaneal width, height, or length. The mean MFS, mean VAS, and complications were not different between the 2 groups. Conclusion Treatment of displaced intraarticular calcaneal fractures with minimally invasive reduction and fixation using either cannulated screws or K-wires can achieve similar excellent functional and radiological outcomes, with high patient satisfaction. The use of K-wires has the advantage of reduced operative time than cannulated screws. Levels of Evidence: Level III: Retrospective comparative study
