Serum S100B Protein Levels in Patients with Panic Disorder: Effect of Treatment with Selective Serotonine Reuptake Inhibitors

ObjectiveAltered serum S100B protein levels have been shown in several psychiatric disorders. Our aim was to investigate whether plasma S100B is different in patients with panic disorder (PD) when compared with controls. Our second aim was to investigate whether treatment with SSRIs have an effect on S100B levels in patients with PD.MethodsThe sample included 32 patients diagnosed with PD (21 women, 11 men) per DSM-IV criteria and 21 healthy controls (11 women, 10 men). S100B levels were measured with BioVendor Human S100B ELISA (Enzyme Linked Immunosorbent Assay) kit.Results14 patients were not on drug treatment (43.8%) while 18 patients were taking various SSRIs. Median S100B value was 151.7 pg/mL (minimum-maximum: 120.4-164.7 pg/mL) in the control group, 147.4 pg/mL (minimum-maximum: 138.8-154.1 pg/mL) in the drug free group and 153.0 pg/mL (minimum-maximum: 137.9-164.7 pg/mL) in the treatment group. Kruskal-Wallis analysis showed a significant diffrerence among the three groups (z=9.9, df=2, p=0.007). Follow up Mann-Whitney-U tests indicated that while the control and the patients with treatment were not significantly different (z=-0.05, p=0.96), there were significant differences between the control group and untreated patients (z=-2.6, p=0.009) and treated and untreated patients (z=-3.0, p=0.003).ConclusionOur results suggested that, serum S100B protein level might be decreased in untreated PD patients and that patients who were treated with SSRIs had similar S100B level to healthy controls.     

Factors affecting symptoms and functionality of patients with carpal tunnel syndrome: a retrospective study

[Purpose] The aim of this retrospective study was to determine the associations between clinical, physical, and neurophysiological outcomes and self-reported symptoms and functions of patients after surgical carpal tunnel release. [Subjects and Methods] Among 261 patients who had undergone open surgical carpal tunnel release within the last three years, 83 (mean age 50.27 ± 11.13 years) participated in this study. Their socio-demographics and comorbidities were recorded. The intensity of pain, paresthesia, and fatigue symptoms in the hand were assessed by means of a Visual Analogue Scale, the Semmes-Weinstein Monofilaments test of light touch pressure sensation, and Jamar dynamometry for measurement of grip and pinch strengths. The Boston Carpal Tunnel Questionnaire evaluated the severity of symptoms and hand functional status, and the variables were analyzed by multivariate linear regression. [Results] The severity of the symptoms and functional status of release surgery patients was associated with diabetes mellitus, migraine, night pain, paresthesia and fatigue symptoms, impaired light touch pressure, and lack of medical treatment. [Conclusion] Appropriate post-surgery treatment programs for these factors should be taken into consideration to help patients obtain optimal functionality and health in their daily lives.Key words: Carpal tunnel syndrome, Patient outcome assessment, Surgical therapy     

Malignant mesothelioma of tunica vaginalis: an extremely rare case presenting without risk factors

Testicular tumours have many different manifestations, including hydrocele formation. Herein, we present an extremely rare case of testicular mesothelioma presenting with left hydrocele, but without risk factors. Left radical inguinal orchidectomy was performed, and pathological examination revealed a malignant mesothelioma of the tunica vaginalis of the testis. No infiltration of the spermatic cord was evident, and upon advanced radiological evaluation, no sign of metastasis was detected. Follow-up was still ongoing in our urology outpatient clinic at the time of this report. Although hydrocele is a simple and common condition that is easy to diagnose, a detailed investigation should be performed. Thus, when encountering a patient with hydrocele, the clinician should evaluate the possibility of the presence of an underlying testicular/paratesticular tumour, including a rare one such as mesothelioma of the tunica vaginalis.     

Body position and obstructive sleep apnea syndrome

In adults, influence of body position on the occurrence of respiratory events during sleep is recognized, and increased numbers of respiratory events occur when the supine position is assumed.1-4 In 1985, Orr et al. showed that body position did not influence respiratory events during sleep in children.5 Recently, Fernandes do Prado et al. showed that children had a lower obstructive apnea hypopnea index (AHI) in supine position.6 Results of these two studies are different from others performed on adults. Moreover, upper airway abnormalities were not considered in these studies.The aim of the present study was to evaluate the effect of body position on obstructive respiratory events in children with different upper airway findings.     

Assessment of Mediastinal Lymph Node Size in Pneumococcal Pneumonia with Bacteremia

Introduction

The significance of mediastinal lymphadenopathy in bacterial pneumonia is unclear.

Methods

We performed a retrospective analysis of mediastinal lymph node size determined by chest CT in patients with bacteremic pneumococcal pneumonia. All patients who had positive blood cultures for streptococcus pneumonia over an 11-year period and had a chest CT scan (index CT) within 2 weeks of the positive blood culture were included in the study. Two thoracic radiologists and one pulmonologist independently examined the index CT plus any chest CT scans performed prior (pre-CT) or after (post-CT) the bacteremic episode.

Results

The study cohort of 49 patients was 57% male, 65% White, with mean age of 53 (SD = 20) years. Mediastinal lymphadenopathy was detected in 25/49 (51%) of the cases. The mean size of the largest mediastinal lymph node in short axis was 0.99 (SD = 0.71), ranging from 0.0 to 2.05 cm. There was no correlation noted between the number of lobes involved with pneumonia, and the size of the largest mediastinal lymph node (p = 0.33) or the number of pathologically enlarged mediastinal lymph nodes (p = 0.08). There was a statistically significant increase in the mean size of the largest lymph node between the pre-CT and index-CT group (p = 0.02), and decrease between the index-CT group and the post-CT (p = 0.03).

Conclusion

Pneumococcal pneumonia with bacteremia is associated with mild mediastinal lymph node enlargement. The presence of marked mediastinal lymphadenopathy (short axis LN size > 2 cm) should not be assumed from pneumococcal pneumonia.

     

Epinephrine-secreting cystic pheochromocytoma presenting with an incidental adrenal mass: a case report and a review of the literature

Cystic adrenal masses are a relatively rare condition, and are usually nonfunctioning and asymptomatic. Differential diagnosis includes pheochromocytoma (PHEO) and adrenal carcinoma; 8-10% of patients with PHEO may be completely asymptomatic. Moreover, fewer than 10% of PHEOs secrete pure epinephrine. We report a case of a E-secreting pure cystic PHEO presenting with an incidental adrenal mass. A 49-year-old Turkish woman was hospitalized at Farabi Hospital for further examinations of a right adrenal cystic mass with a thick wall that was incidentally discovered by abdominal ultrasonography during examination for nausea, vomiting, headache, and angina-like chest pain in another hospital. On admission, her blood pressure was 100/60 mmHg. Tension Holter monitoring revealed paroximal hypertension (178/136 mmHg) and hypotension (78/54 mmHg) attacks. Of urinary catecholamines and its metabolites, only urine metanephrine was markedly increased, despite a urine epinephrine level near the upper limit of normal ranges. Abdominal computed tomography and magnetic resonance imaging studies revealed a cystic round tumor approx 5 cm in diameter, located in the right adrenal gland. Right adrenalectomy was performed; the surgical specimen revealed pure cystic PHEO. Postoperatively, the urine metanephrine level returned to normal range and urine epineprine level was decreased approx 60%. In conclusion, a diagnosis of E-secreting PHEO should be considered in patients with nonspecific symptoms, presenting with an incidental cystic adrenal mass, even in the absence of hypertension.     

An unusual primary left ventricular hydatid cyst complicated by cardiac tamponade and mitral regurgitation--a case report

Cardiac involvement in hydatidosis is rare but because of potentially lethal complications, its recognition is of great importance. The authors present a 55-year-old woman admitted to the clinic with cardiac tamponade and moderate mitral regurgitation caused by a hydatid cyst located at the inferoposterior wall of the left ventricle.
