Microalbuminuria is associated with the severity of coronary artery disease independently of other cardiovascular risk factors

The potential early predictive value of microalbuminuria (MA) in the estimation of atherosclerosis and the relation between the degree of urinary albumin excretion and the extent of coronary artery disease (CAD) were investigated. Patients (n = 159) with stable angina pectoris and angiographically significant stenosis in at least 1 of the major coronary arteries were included. Microalbuminuria was measured by immunoturbidimetry. The extent of coronary artery stenosis was graded using the Gensini score. The Gensini score was significantly greater in patients who had MA. Also, the Gensini increased by 0.15 units with 1 unit increase in MA. In the groups who had diabetes mellitus and hypertension, there was no correlation between MA and Gensini score. The results of the present study suggest that MA is associated with the severity of CAD independent of other cardiovascular risk factors.     

Protective effects of N-acetylcysteine on the peroxidative changes of rat lungs exposed to inhalation of thinners

OBJECTIVE: Long-term inhalation of thinners may cause damage, both to the lungs and to other organ systems. It causes cellular damage via formation of reactive oxygen species. The lung is protected from oxidative stress by the glutathione (GSH) antioxidant system which can be augmented by the thiol drug, N-acetylcysteine (NAC). This study investigated the protective effect of NAC on peroxidative changes in rat lungs exposed to inhalation of thinners for 8 weeks. METHODOLOGY: Seventy-two male Wistar albino rats were used and divided into two groups: one group inhaled only thinners (TI), while the other inhaled TI plus NAC. Rats in the TI and TI + NAC groups were divided into four subgroups (each consisting of eight rats) according to the duration of exposure to TI: 2, 4, 6 and 8 weeks. A control group (n = 7) of rats inhaled neither TI nor NAC. Malondialdehyde (MDA) and GSH levels, and superoxide dismutase (SOD) activities were determined in the lung tissues. Histopathological findings were evaluated as acute and chronic changes in the alveoli and interstitium in the TI and TI + NAC groups and compared with those in the control group. RESULTS: While tissue MDA levels in the groups inhaling TI for 4, 6 and 8 weeks were significantly higher than those in the control groups (P < 0.01, P < 0.01, P < 0.0001, respectively), GSH levels were significantly lower (P < 0.05, P < 0.01, P < 0.01, respectively). Tissue SOD activities in the groups inhaling TI for 6 and 8 weeks were significantly lower than those in the control group (P < 0.05, P < 0.01, respectively). In the TI group, MDA levels were significantly increased (P < 0.01) with increasing duration of inhalation (from the second week through to the eighth week), while GSH levels and SOD activities were significantly decreased (P < 0.01, P < 0.01). Tissue MDA levels were significantly lower in the TI + NAC groups across all inhalation periods, when compared with the TI groups (P < 0.01, P < 0.0001, P < 0.0001, P < 0.0001, respectively). Tissue GSH levels in the TI + NAC groups were significantly higher than those of the TI groups (respective values: P < 0.05, P < 0.01, P < 0.01, P < 0.0001). Tissue SOD activities in the TI + NAC groups were significantly higher than those of the TI groups (respective values: P < 0.05, P < 0.0001, P < 0.05, P < 0.0001). Pathological examinations with light microscopy did not show any beneficial effect of NAC application in terms of deferring or alleviating the negative effects of TI. CONCLUSIONS: Thinners are agents that cause imbalance between oxidants and antioxidants produced by aerobic cellular systems. This imbalance between oxidant and antioxidant systems is decreased by the effect of NAC. However, ultrastructural studies may be needed to substantiate this evidence morphologically, as light microscopy was inconclusive.     

Allergic contact dermatitis from Laurus nobilis oil induced by massage

Non-occupational contact allergy to Laurus nobilis (laurel) oil is considered rare. Herein, we report a case of allergic contact dermatitis after a massage with a mixture of olive oil and L. nobilis oil. Patch testing showed (+++) reactions to laurel oil and (++) to the mixture of olive oil and laurel oil.     

Serum M65 as a Biomarker for Metastatic Renal Cell Carcinoma

Introduction/BackgroundEffective cancer biomarkers for early detection, prognosis, or therapy response prediction are urgently need in metastatic RCC. M30 and M65 are released during apoptotic cell death and precisely reflect epithelial tumor cell death. The aim of this study was to determine the prognostic value of plasma M30 and M65 levels in predicting survival rates for patients with metastatic RCC.Patients and MethodsThirty-nine patients with metastatic RCC and 39 healthy control subjects were included in this study. Serum M30 and M65 levels were measured by ELISA.ResultsThe median ages of the patients and control subjects were 60 and 58 years, respectively. No difference was detected in the median serum M30 level between the patients and control subjects (53.7 vs. 49.1 U/L; P = .31). The median serum M65 level was significantly higher in patients than in control subjects (334.0 vs. 179.1 U/L; P < .001). Receiver operating characteristic analysis revealed that the best cutoff value for serum M65 level for predicting progression-free survival (PFS) was 313.6 U/L. The median PFS of patients whose M65 levels were ≤ 313.6 U/L was better than that of patients whose M65 levels were > 313.6 U/L (P = .03).ConclusionTo the best of our knowledge, this is the first study to evaluate serum M30 and M65 levels in patients with RCC. Serum M65 levels were significantly elevated in patients with metastatic RCC compared with healthy individuals. In addition, the serum M65 level could be predictive of PFS in patients with RCC.     

Ranitidine‐induced black tongue: A case report

Black tongue is a rare, benign, self‐limiting disorder caused by certain conditions and some medications. We report the first case of a child diagnosed with black tongue associated with ranitidine use. We report our case to emphasize the rare side effect of this frequently used drug. Health care professionals should be aware of the likelihood of ranitidine‐induced black tongue in clinical practice.     

The concept of crosstalk‐directed embryological target mining and its application to essential hypertension treatment failures

This review aims to introduce the novel concept of embryological target mining applied to interorgan crosstalk network genesis, and applies embryological target mining to multidrug‐resistant essential hypertension (a prototype, complex, undertreated, multiorgan systemic syndrome) to uncover new treatment targets and critique why existing strategies fail. Briefly, interorgan crosstalk pathways represent the next frontier for target mining in molecular medicine. This is because stereotyped stepwise organogenesis presents a unique opportunity to infer interorgan crosstalk pathways that may be crucial to discovering novel treatment targets. Insights gained from this review will be applied to patient management in a clinician‐directed fashion.     

Prenatal diagnosis of dicephalic parapagus conjoined twins

Dicephalic parapagus is a rare anomaly of monochorionic twinning. We present prenatal diagnosis of this anomaly with ultrasonography and magnetic resonance imaging. She was at the 19th week of gestation. Even if earlier diagnosis is possible, this was her first examination unfortunately. Baby had two head and a common trunk. This is one of the rarest twinning. Termination of pregnancy is performed and baby is delivered by cesarean section. Imaging findings of the case are illustrated and discussed with the autopsy findings.
