As public awareness of the various warning signs of malignancy increases, so does the concern evoked by the self identified finding of mass in the head and neck area. Not all the palpable masses are always significantly abnormal, but any nontender mass especially to the adult is significant enough to warrant further full investigation and follow up, the object of which should be to determine the possibility of malignancy and urgency of treatment. Approach to the diagnosis of the neck mass is so important in that it affects decision regarding further evaluation would lead to the determination of the most efficacious mode of therapy, eventually to the good prognosis. So, it should be emphasized that approach to the diagnosis of neck mass should be planned, systematic and thorough, this begins with the taking careful history following performance of complete examination of the head and neck especially to the nasopharynx, tongue base, pyriform sinus, palatine tonsil and larynx. Then a number of laboratory and radiologic studies are available, following triple endoscopy under general anesthesia and blind biopsy if needed. The most important rule to keep is that any biopsy procedures should be delayed to the last modality of effort to the diagnosis and if it should be done, under the plan of radical neck dissection.

Objective:
This study determined the threshold for recurrent depressive episodes that predicted conversion from major depressive disorder (MDD) to bipolar disorder (BD).
Methods:
We retrospectively reviewed the medical records of 296 patients diagnosed with MDD for a minimum of 5 years in two university hospitals. We examined their the Diagnostic and Statistical Manual of Mental Disorders, 5th edition diagnoses and detailed clinical information at the initial admission and yearly assessments after discharge to establish the threshold for recurrent depressive episodes indicating a risk of diagnostic conversion from MDD to BD. Optimal cut-offs were derived using receiver operating characteristic (ROC) curves.
Results:
ROC curve analysis revealed that more than four recurrent depressive episodes was indicative of potential diagnostic conversion from MDD to BD (area under the curve, 0.604; sensitivity, 0.353; specificity, 0.855; positive predictive value, 0.421; negative predictive value, 0.816).
Conclusion
These findings suggest that the best predictor of conversion from MDD to BD is more than four recurrent depressive episodes. Our findings have the potential to enhance diagnostic accuracy and treatment efficiency. To validate our results, longitudinal prospective studies are necessary.

Background:
Metformin (MET) has been used to prevent weight gain in patients treated with antipsychotic drugs. However, liraglutide (LIRA), initially used for diabetes, is now considered for obesity treatment. The aim of this study was to investigate the effectiveness and safety of these drugs in patients with psychiatric disorders.
Methods:
A retrospective chart review was performed on patients prescribed and administered MET and LIRA from January 1, 2017 to August 31, 2023. To assess treatment efficacy, the mean change in the body mass index of the patients before and after drug use was calculated for both medications. Drug safety was evaluated by determining the early discontinuation and occurrence of adverse effects.
Results:
We collected data from 45 patients, with the majority being women (84.4%). The most frequently diagnosed psychiatric disorders were depressive disorder for LIRA (35.3%) and psychotic disorder for MET (63.6%). No demographic variations were observed between patients who were administered the two types of drugs. The treatment efficacy and safety of both drugs did not show any statistically significant difference. When conducting a subgroup analysis exclusively on patients diagnosed with psychotic disorders (n = 14), MET showed better efficacy; however, no statistically significant difference was observed (−2.48±3.17 vs. 0.56±2.93, t=−1.860, p=0.088).
Conclusion
LIRA and MET did not show any significant differences in terms of therapeutic efficacy and safety. However, in patients diagnosed with psychotic disorders, MET showed better efficacy and was cost-effective than LIRA. Future studies with larger sample sizes are required to confirm these findings.

PURPOSE: We analysed the role of modified Gianturco self-expandable stents in the treatment of tracheobronchial stenosis in 13 patients. MATERIALS AND METHODS: We inserted modified Gianturco self-expandable stents under the fluoroscopic and bronchoscopic guidance. There were stenosis in the trachea(n--2), the right main bronchus(n=2), and the left main bronchus(n=9). The causes of the stenosis were endobronchial tuberculosis(n=10), intubation granuloma (n=l), restenosis after surgical reconstruction(n=2). RESULTS: Dyspnea or wheezing was improved within 1 or 2 days following the procedure. There were 32% and 22% respective increase in average FEV1 and FVC. Lung perfusion scan showed 9.6% increase of perfusion in the involved lung. No complications related to the procedure were encountered. During follow-up period of up to 31 months, 2 patients showed tracheal or bronchial restenosis, at 3 and 6 months, retrospectively. There was a distal migration of the stents in one case. CONCLUSION: During the follow up period after stent insertion, improvement of the obstructive changes and dyspnea persisted in 10 out of 13 patients. The modified Gianturco self-expandable metallic stents may be a good choice for the treatment of tracheobronchial stenosis, either as a primary treatment, or when the reconstruction failed.

PURPOSE: The purpose of this study was to determine the following:the safety of fine needle aspiration biopsy in immunocompromized children with radiographic features of Pneumocystis car/nil pneumonia, its diagnostic rate in those groups and the appropriate radiographic stage for fine needle aspiration biopsy to prove the etiologic agent. METHODS AND MATERIALS: We retrospectively reviewed the patient records of 16 children with immune compromizing diseases who had undergone fine needle aspiration biopsy of the lung. They showed the infectious sign of the lung along with the radiographic pattern of diffuse pulmonary disease, suggesting Pneumocystis carlnil pneumonia. All patients had underlying lymphoreticular malignancies including 14 acute lymphocytic leukemia and 2 non Hodgkin's lymphoma. According to the radiographic pattern of biopsy site, parenchymal disease was categorized as fine reticulonodular density(n=4), ground-glass opacity(n=9) and compact consolidation(n=3). We assessed the diagnostic rate of Pneumocystis carinii pneumonia and complications in each of the three groups. RESULTS: A diagnosis of Pneumocystis carinii pneumonia was established by fine needle aspiration biopsy in 9 patients(56%) including 2 of 4 patients with fine reticulonodular density, 4 of 9 patients with ground-glass opacity, and all 3 patients with compact consolidation. Four patients(25%) developed pneumothorax, and three of them required tube insertion. There was no patient who developed hemoptysis. CONCLUSION: Fine needle aspiration biopsy is a safe and easy method that can yield Pneumocystis carinii organism at a relatively high rate in immunocompromized children with diffuse pulmonary lesions suopicions of Pneumocystis carinii pneumonia. We recommend performing fine needle aspiration biopsy regardlesss of radiographic patterns when Pneumocystis carinii pneumonia is suggested.
