ABSTRACT

OBJECTIVE: Patients with chronic disease whose treatments are limited may experience depression, anxiety, and stress-related symptoms, as well as an increase in the levels of these conditions. This study aims to determine the factors affecting the depression, stress, and anxiety levels of hepatocellular carcinoma (HCC) patients due to the fear of COVID-19 exposure. PATIENTS AND METHODS: 118 patients with advanced HCC treated with non-transplant treatment options or on the waiting list due to the lack of a donor were enrolled. To evaluate the stress, depression, and anxiety levels during the COVID-19 process, Depression Anxiety Stress Scales (DASS-21) and the Coronavirus Anxiety Scale (CAS) were administered to 118 patients through a face-to-face interview. Sociodemographic and clinical characteristics were recorded, and the primary endpoint measure was the total score of DASS. In addition, the multilayer perceptron (MLP) model was constructed to predict the scores of the DASS-21 total. RESULTS: There were significant differences between DASS depression (p=0.010; p=0.030) DASS anxiety (p=0.010; p=0.010) and DASS total (p=0.046; p=0.023) scores in terms of gender and protective effect of the vaccine. Also, a significant difference between gender for the CAS scale was determined (p=0.044). The median score of the DASS total in the COVID-19 group was higher than in the non-COVID-19 group; however, the increase was not significant. MLP model revealed that chronic disease, gender, age, place of residence, smoking, type of vaccine, and COVID-19 exposure were the most important predictors for the DASS total. CONCLUSIONS: Chronic disease, gender, and age were prominent factors in predicting the DASS-21 total score in HCC patients. Therefore, the crucial factors were clinically considered for managing depression, stress, and anxiety in HCC patients.

ABSTRACT

Appendectomy is one of the most frequently performed operations. Stump appendicitis, as a postoperative complication of appendectomy, is inflammation of the remnant residue when an incomplete excision occurs. We present a patient with stump appendicitis who had been operated on, laparoscopically, for acute appendicitis 6 months before. The patient was diagnosed with acute appendicitis, underwent surgery, and was discharged on postoperative day 3 without complications. Stump appendicitis is a rare cause of acute abdominal disease but should be considered in the differential diagnosis. Ultrasonography is helpful in the diagnosis.

ABSTRACT

AIM: To compare the effects of laparoscopic versus conventional inguinal hernia repair techniques on patients physical activity. MATERIALS AND METHODS: Ninety-three patients (between 20 and 59 years old) who presented with a need for inguinal hernia repair at the private Safa Hospital, General Surgery Clinic, were evaluated prospectively between November 2011 and March 2013. The patients mean age was 46.1 (+-12.9) years. They were divided into three groups according to hernia repair technique. Thirty underwent total extraperitoneal repair (TEP), 31 had transabdominalpreperitoneal repair (TAPP) and 32 had modified Bassiniprolene mesh grafting (MBPMG). All patients were examined in the physical therapy and rehabilitation unit just before and after the operation. Lower extremity muscles isokinetic and isometric functions were measured with the Cybex isokinetic testing device. Patients length of stay in hospital, need for analgesics in the postoperative period, visual analogue scale (VAS) scores, time of return to work and postoperative complications were also compared. RESULTS: Patients need for postoperative analgesics, the use of VAS scoring system (between 0 and 10), complication rates and the patients VAS scores on movement results were similar to those in the literature. On the postoperative third day, measurements recorded by the Cybex isokinetic testing device showed that the loss of strength in the lower extremities after the MBPMG procedure was greater than with TAPP and TEP. The isokinetic and isometric assessment of all cases revealed that postoperative mean muscle strength loss was two-thirds less in association with the laparoscopic procedure. Within a 95% confidence interval (CI), the significance of findings was accepted at P-values of less than 0.05 (p 0.05). CONCLUSION: The quantitative data showed that there is a more favourable impact from laparoscopic hernia repair versus open surgery on patients physical activity and return to active work.

ABSTRACT

Cellular immune response and delayed-type hypersensitivity reactions are considered to play a major role in the immunopathogenesis of pulmonary tuberculosis (PTB). But the exact mechanism is still to be clarified. Th1 cells are mainly involved in cellular immune responses in PTB and provide a normal healing process with minimal or no sequela whereas Th2 cell and CD8(+) T lymphocyte responses may lead to more severe type of disease. In this study, we investigated the peripheral blood immune responses in PTB. The study group consisted of acid fast positive young male soldiers with PTB and a negative HIV serology. The control group included healthy young volunteer male soldiers without a history of PTB. Intracytoplasmic cytokine content of CD8(+) T cells and lymphocytes, including IL-2, IL-4, IL-5, IL-10 and IFN-gamma were determined by flow cytometry, and IL-2, IL-4, IL-5, IL-10, IFN-gamma and TNF-alpha serum levels were measured by cytometric bead array (CBA). No difference was observed between the percentages of T, B, NK cells and HLA-DR expression in both groups, however, the number of CD3(+)HLA-DR(+) activated T cell percentages was higher in PTB group as compared to healthy subjects. IL-2, IL-4, IL-5, IL-10 contents of lymphocytes and IFN-gamma(+)CD8(+) T cells were found to be significantly lower in PTB patients when compared with healthy subjects, and in parallel, serum IL-2, IL-4, IL-5 and TNF-alpha levels were also significantly lower in PTB patients. In conclusion we suggest that, CD8(+) T cells producing both Th1 and Th2 type cytokines, may play important role in the peripheral immune response to mycobacteria.

ABSTRACT

OBJECTIVE: To present four rare cases of congenital unilateral tubal and ovarian abnormalities with their laparoscopic images. DESIGN: Case report. SETTING: Baskent University Faculty of Medicine, Department of Obstetrics and Gynecology, Konya, Turkey. PATIENT(S): Three patients with infertility showing abnormality on hysterosalpingography and a fourth patient with acute pelvic pain who were admitted to our clinic. INTERVENTION(S): All four patients underwent laparoscopic surgery. MAIN OUTCOME MEASURE(S): Case 1 showed an absence of a distal tubal segment with ipsilateral ovarian agenesis. Case 2 showed a unilateral partial distal tubal absence with normal adjacent ovary. Case 3 showed a twisted and adherent tube with ipsilateral ovarian absence. Case 4 showed a unilateral ovarian agenesis and contralateral acute adnexal torsion. RESULT(S): We detected four cases of unilateral ovarian and partial tubal absence in these operations. CONCLUSION(S): We present four unusual cases of unilateral ovarian and partial tubal absence. The absence of one ovary and tube may be explained by two possible etiopathogenic causes: asymptomatic adnexial torsion or congenital malformation.

ABSTRACT

BACKGROUND: Th1 cytokines, IL-2 and IFN-gamma , have critical importance in the CD4 cell driven antimycobacterial activity. Th2 type immune response is a characteristic feature of atopic disorders. Th1 and Th2 cells have been reported to negatively cross-regulate each other in vitro and in experimental animals. Our aim in the present study is to determine whether the atopy affects radiological extent of pulmonary tuberculosis (TB) and disease severity. MATERIALS AND METHODS: A total of 82 male patients with pulmonary TB were prospectively enrolled in the study between March 2005 and March 2006. All patients were evaluated for atopic symptoms and TB related systemic symptoms. Radiological dissemination was scored and cavitation was noted. The skin prick test (SPT) was performed and serum total IgE level was measured. RESULTS: The SPTs were positive in 28 of 82 (34.1 %) patients. There was no distinction between SPT-positive and negative patients in terms of pulmonary cavitation and radiological dissemination. The median IgE level of moderate-severe radiologically disseminated TB patients was significantly higher than that of mild radiologically disseminated TB patients (130 IU/ml vs. 58 IU/ml). Cavitary TB patients had also significantly higher median IgE levels (78 IU/ml vs. 46 IU/ml) (p < 0.05) CONCLUSION: This study suggests that SPT-positivity and atopic respiratory phenotype do not affect the formation of cavitation, radiological dissemination and systemic symptoms of pulmonary TB. The high level of IgE in patients with cavitary and radiologically disseminated TB may be a consequence of a dysregulated immune response to infection or reflect disease activity.

ABSTRACT

This study investigated the relationship between the atopic phenotype and the development of active tuberculosis. A total of 82 human immunodeficiency virus negative males with active pulmonary tuberculosis and 88 healthy controls were enrolled into this prospective study. Serum immunoglobulin E (IgE) levels were measured and skin prick tests performed before initiation of treatment. Skin prick tests were positive in 34.1% of the tuberculosis patients and 39.8% of the controls. Allergic respiratory symptoms were significantly less frequent in skin prick test positive tuberculosis patients (21.4%) compared with skin prick test positive controls (62.9%). Median IgE levels in atopic tuberculosis patients were significantly higher than in atopic controls. The low rate of atopic respiratory complaints seen in the tuberculosis patients, despite having similar allergic skin prick test sensitivities to the controls, could be attributed to a weak T-helper (Th) 2 immune reaction and its effects on Th1-Th2 interaction.

ABSTRACT

Infections, such as tuberculosis, measles and diphtheria, may decrease the risk of developing atopic allergic disorders. Patients with pulmonary TB having similar allergic skin prick test sensitivity as healthy controls but unable to show vigorous atopic phenotype in their healthy period might be a sign for Th1-Th2 immune interaction.

ABSTRACT

We investigated the clinical significance of brain natriuretic peptide (BNP), a cardiac hormone, in chronic obstructive pulmonary disease (COPD). Subjects were 38 patients with stable COPD, of whom 20 had cor pulmonale (CP), and 22 were healthy individuals. Plasma BNP levels were measured and pulmonary arterial pressure (PAP) was estimated by echocardiography. Arterial blood gas analysis, forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) were also recorded. BNP levels of patients with COPD were higher than those of controls (48.2 +/- 37.5 and 9.3 +/- 3.0 pg/ml). Patients with CP had a higher mean BNP level with respect to those without CP (73.9 +/- 35.8 and 21.0 +/- 10.2 pg/ml, respectively). BNP levels correlated with PAP (r = 0.68), partial arterial oxygen pressure (r = -0.70), FEV1 (r = -0.65) and FVC (r = -0.52). We have concluded that BNP determination has a role in the diagnosis of CP in patients with COPD.

ABSTRACT

SETTING: Pulmonary department of a medical academy in Ankara, Turkey. OBJECTIVE: Neopterin is a marker of cell-mediated immunity, and it has been demonstrated that neopterin levels of various body fluids could be elevated in tuberculosis. We aimed to investigate diagnostic values of serum, pleural fluid and urine neopterin measurements in tuberculous pleurisy (TP). DESIGN: Serum, pleural fluid and urine neopterin levels were measured in 34 patients with TP and in 29 patients with pleural effusion of non-tuberculous origin as controls. RESULTS: Neopterin levels in serum, pleural fluid and urine (38.28 +/- 14.18 nmol/l, 38.97 +/- 14.18 nmol/l and 759.15 +/- 622.74 micromol/mol, respectively) were significantly higher in patients with TP than those with non-tuberculous pleural effusion (22.57 +/- 6.02 nmol/l, 21.88 +/- 6.90 nmol/l and 343.10 +/- 233.65 micromol/mol, respectively). Pleural fluid neopterin > or =30 mol/l gave the best diagnostic yield, with 85% sensitivity, 93% specificity, 94% positive predictive value, 84% negative predictive value and 89% diagnostic accuracy, although it is not superior to pleural fluid adenosine deaminase determination. CONCLUSION: We have suggested that elevated serum, pleural fluid and urinary neopterin levels in TP with respect to pleural effusions of non-tuberculous origin may reflect activation of cell-mediated immunity and that pleural fluid neopterin measurement may be of value in the differential diagnosis of TP.

ABSTRACT

AIM: We hypothesised that serum calcium (Ca) and parathormone (PTH) levels correlate with radiological extent and that there may also be a relationship between the tuberculin skin test (TST), serum Ca and PTH levels in patients with pulmonary tuberculosis (PTB). MATERIALS AND METHODS: Forty-four patients with active PTB and 33 healthy subjects were enrolled in the study. Serum Ca, PTH, magnesium and phosphate levels were measured in patients and controls and compared. Correlations were also investigated for TST values, erythrocyte sedimentation rate (ESR), the degree of radiological involvement, serum PTH and corrected Ca levels. RESULTS: There was a significant difference between the two groups for mean serum PTH and corrected Ca levels. Significant correlations were detected between radiological extent of disease and serum PTH levels, between TST values and serum PTH levels and between ESR and serum PTH levels. We suggest that abnormal Ca metabolism in PTB patients is related to the radiological extent of disease. Factors determining the radiological extent of disease, predominantly the patient's immune status, may have an important role in modulating Ca metabolism in PTB patients.

ABSTRACT

OBJECTIVE: Precise epidemiological data are essential to increase the efficiency of a tuberculosis (TB) control programme. In some countries significant numbers of TB cases go unrecorded or undetected. We aimed to investigate the incidence of TB in the Turkish Armed Forces (TAF), to obtain more reliable data on the entire population. DESIGN: In 2001, all soldiers with a new diagnosis of TB were enrolled in the study based on the official records of 14 military hospitals. The demographic data of the cases were evaluated. RESULTS: Six hundred and twenty-nine conscripts with TB were detected. Of these, 574 were aged between 20-24 years and 392 were smear-positive. The incidences of TB and smear-positive cases in TAF conscripts were calculated at respectively 76 and 47 per 100,000 population. When the age and sex distribution of the Turkish population and TB cases in Turkey were considered, the incidences of all TB and smear-positive TB in Turkey were estimated at respectively 33 and 17/100,000. These numbers are very close to those estimated by the World Health Organization. CONCLUSION: In countries where military service is compulsory and case detection rates are low, the TB incidence of the armed forces is a reliable reflection of the rate in the whole population.

ABSTRACT

PURPOSE: To report the outcome of a step-by-step treatment approach for congenital nasolacrimal duct obstruction (CNDO). METHODS: Three-hundred and fifty eyes with CNDO were included in the study. A number of treatment methods were applied systematically until a successful outcome was achieved. Listed in order from simple to more complex, the following methods were used: conservative management (massage and topical antibiotics), high-pressure syringing, probing, and silicone intubation. Treatment efficacy was determined according to age (Group 1: 0-6 months, Group 2: 7-12 months, Group 3: 13-24 months, Group 4: 25-72 months) and success rates were compared. RESULTS: Conservative management was applied only in children less than 1 year of age, and was successful in 91.8% of Group 1 and 60% of Group 2 eyes. The difference between these two success rates was significant (p = 0.003). High-pressure syringing was performed in children under 24 months of age, with success rates of 41.7% in Group 1, 33.3% in Group 2, and 12.5% in Group 3. The overall success rate for first probing in all groups was 76.1%, with a range of 69.4% to 80.9%. After second probing, the overall cure rate for the entire cohort was 88.0%, with a range of 74.9% to 94.8%. There was no real difference in probing cure rates relative to age (p > 0.05). Silicone intubation was indicated and performed in two eyes of Group 2 children, three eyes of Group 3, and nine eyes of Group 4. Two ducts in Group 4 eyes remained obstructed after silicone intubation. CONCLUSIONS: The systematic treatment approach to CNDO, including conservative management and minimally invasive procedures such as high-pressure syringing, probing, and silicone intubation, is highly successful. In this study, the cure rate for this combined approach was 100% in youngsters under 2 years of age and 94.5% in children 2 to 6 years old.

ABSTRACT

PURPOSE: To analyze the results of excimer laser phototherapeutic keratectomy (PTK) combined with simple excision in recurrent pterygium to minimize the recurrence rate and obtain a smooth corneal surface. SETTING: Veni Vidi Eye Health Centre, Istanbul, Turkey. METHODS: Combined pterygium excision and excimer laser PTK was performed in 22 eyes with recurrent pterygium (22 patients). Both spot and scan modes of the Meditec MEL 60 excimer laser were used to produce a wide ablation layer (depth 40 to 80 microns). RESULTS: During the mean follow-up of 16.5 months (range 6 to 27 months), visual acuity, refraction, slitlamp, and corneal topography examinations were recorded. Pterygium recurred in only 1 eye (4.5%). Postoperative visual acuity improved in 15 eyes (68.2%). Keratometric readings were not accurately measured preoperatively because of corneal surface irregularities but could be easily taken after the surgery. Corneal astigmatism ranged from 0 to 2.00 diopters (D) (mean 1.23 D). Three months after surgery, no haze persisted in any eye. No significant intraoperative or postoperative complication was detected. CONCLUSIONS: Excimer laser PTK appears to simplify pterygium surgery because a superficial keratectomy is sufficient to remove pterygium. The excimer laser can be used to ablate the visible residual tissues and smooth the corneal surface, resulting in good postoperative refraction and visual acuity. Consequently, this procedure seems to be effective and safe.

ABSTRACT

The aim of this study is to investigate the value of Tc-99m tetrofosmin (Tc-99m-TF) in conjunction with conventional Tc-99m-pertechnetate (Tc-99m-P) scintigraphy in the differentiation of malignant nodules from benign thyroid nodules. Forty-two patients [(32 females, 10 males; mean age 41 +/- 13 years; twenty-two multinodular goiter (MNG) patients with 58 nodules and 20 solitary thyroid nodules (STN)] were included in the study. Thyroid scintigraphy with Tc-99m-P and Tc-99m-TF, thyroid ultrasonography and fine needle aspiration cytology (FNAC) were performed. After i.v. injection of 370-550 MBq Tc-99m-TF, images were obtained at 15 minutes and evaluated semiquantitatively by using a five point (0-4) scoring system. Four patients with a hypoactive STN, and 1 patient with a hypoactive MNG was found to have thyroid malignancy by histopathological examination; 2 of these patients had false negative benign FNAC results. The tetrofosmin uptake score (TUS) was 2-3-3-3 and 3 in these 5 malignant nodules. Five hyperactive (hot or warm) STN with benign FNAC had a TUS of 2-3-3-3-3. All hypoactive (cold) MNG nodules with benign FNAC (n = 21) had TUS < or = 2. Our preliminary results suggest that follicular adenomas and thyroid cancers have higher tetrofosmin uptake than benign colloidal goiter nodules. Mitochondrial sequestration of tetrofosmin in benign or malignant follicular cells that proliferate more rapidly than normal follicular cells and/or hypervascularity may be responsible for this. The use of Tc-99m-TF in conjunction with Tc-99m-P thyroid scintigraphy will be helpful in the evaluation of patients with nodular goiter (NG). In patients with a STN, a hypoactive nodule with a high TUS has a higher probability of malignancy; whereas a hyperactive nodule with a high TUS is a follicular adenoma. In patients with MNG, a hypoactive nodule with a high TUS may be suggestive of malignancy despite a benign FNAC result. We think that further studies with Tc-99m-TF are required to confirm these results.

ABSTRACT

Although tuberculosis is common and well recognised in many countries, unusual presentations of the disease sometimes raise difficulties in differential diagnosis. We report a young patient who presented with weight loss, shortness of breath and easy fatiguability. Extensive lymphadenopathy involving the cervical, axillary and inguinal regions were found on physical examination. Chest X-ray and computed tomography revealed generalized lymphadenopathy of cervical, mediastinal and para-aortic chains, bilateral pulmonary miliary reticulonodular infiltrates, pleural effusion, hepatomegaly with low density, macronodular hypodense areas in spleen, ascites, peritoneal irregularity and thickening of bowel walls. Mantoux test was negative. Peritoneal fluid was exudative, but pleural fluid was transudative, probably due to mediastinal lymphatic obstruction. The initial clinical diagnosis was malignant lymphoma; however, positive sputum smears for mycobacteria and excisional cervical lymph node biopsy revealing caseating granulomatous lymphadenitis were consistent with tuberculosis. The patient responded well to appropriate therapy with regression of radiological abnormalities.
