The triglyceride-glucose index as a predictive marker for coronary slow flow phenomenon

OBJECTIVE

The triglyceride-glucose index (TyG) has been proposed as a marker of insulin resistance (IR) and has shown associations with cardiovascular diseases. This study aimed to investigate the relationship between the TyG and the coronary slow flow phenomenon (CSFP) and explore the index's potential as a predictor of this condition.

PATIENTS AND METHODS

A total of 187 patients who underwent coronary angiography were included; of these, 91 patients were diagnosed with CSFP, and 96 patients with normal coronary flow served as a control group. The TyG was calculated using fasting triglyceride and glucose levels.

RESULTS

The results showed that the TyG was significantly higher in the CSFP group compared with the control group (p < 0.001). Additionally, the TyG exhibited a moderate positive correlation with the thrombolysis-in-myocardial-infarction frame count in coronary arteries (p < 0.001). A multivariate logistic regression analysis revealed that the TyG, along with gender, ejection fraction, and uric acid, remained significant predictors of CSFP (p < 0.05).

CONCLUSIONS

This study's findings suggest that the TyG may serve as a useful marker for identifying individuals at risk of CSFP and provide insights into the potential role of IR in its pathophysiology.

Factors affecting survival in patients undergoing percutaneous transhepatic biliary drainage for malignant biliary obstruction

OBJECTIVE

The general approach to malignant biliary obstruction (MBO) is to provide drainage in all patients with jaundice. However, the procedure is often palliative, and its contribution to survival is debated. This study aimed to investigate prognostic factors in patients undergoing percutaneous transhepatic biliary drainage (PTBD) for MBO.

PATIENTS AND METHODS

All laboratory values were divided into two groups based on median values: low and high. Chi-square analysis was performed for dichotomous data. The time from the PTBD procedure to the date of death or last follow-up was considered overall survival (OS). Univariate and multivariate analyses were calculated using the Cox regression model.

RESULTS

A total of 152 patients were included in the study, of whom 84 (55.3%) were male. The median OS was 71 ± 12.6 days (95% CI: 46.3-95.7). The 1, 3, 6, and 12-month OS rates were 74.3%, 45.2%, 29.2%, and 13%, respectively. In the multivariate analysis, comorbidity (p=0.029), Eastern cooperative oncology group performance status (ECOG PS) (p=0.007), pre-PTBD albumin (p=0.025), post-PTBD aspartate aminotransferase (p=0.025), chemo naive (p<0.001), and post-PTBD chemotherapy (CT) (p=0.01) were found to be independent prognostic factors.

CONCLUSIONS

In patients with poor prognosis MBO, the decision for PTBD should be made multidisciplinarily, taking into consideration ECOG PS, comorbidities, albumin levels, and prior CT status.

Comparison of clopidogrel vs. ticagrelor medication adherence in patients with acute coronary syndrome

OBJECTIVE

Medication nonadherence to dual antiplatelet therapy increases major cardiovascular events. In this study, we investigated patients' post-acute coronary syndrome (ACS) medication adherence to clopidogrel and ticagrelor over a 12-month period. Furthermore, we also examined the factors that may affect medication adherence in this patient population.

PATIENTS AND METHODS

This study included 509 patients who were scheduled for dual antiplatelet therapy for one year following ACS (October 2018-December 2019). A proportion of days covered (PDC) method, based on a pharmacy database system, was used to determine their medication adherence. Medication adherence was defined as > 80% PDC.

RESULTS

No difference was found between clopidogrel and ticagrelor in terms of medication adherence (68.3% vs. 64.6%, p = 0.39). Moreover, higher education levels (B = 3.24, CI: 1.17-8.9, p = 0.023) and percutaneous coronary intervention (PCI) as a revascularization option (B = 0.35, CI: 0.17-0.71, p = 0.004) predicted medication adherence independently.

CONCLUSIONS

In this research, medication adherence was found to be similar between the clopidogrel and ticagrelor groups. It was also predicted by higher education levels and revascularization with PCI.

The effects of Digoxin use on long-term prognosis in patients with heart failure with reduced ejection fraction

OBJECTIVE

This study aimed to investigate the effect of digoxin on mortality and rehospitalization in heart failure with reduced ejection fraction (HFrEF) patients. Heart failure is a clinical syndrome that requires frequent rehospitalization and has a high mortality. This study aimed to investigate the effect of digoxin on mortality and rehospitalization in patients with heart failure with reduced ejection fraction.

PATIENTS AND METHODS

The study included 326 patients with HFrEF that were hospitalized for decompensation between September 2014 and January 2016. The patients were divided into two groups: digoxin users and a control group. The study's endpoints were cardiovascular death and rehospitalization after 24-month long-term follow-ups.

RESULTS

Rehospitalization was lower in patients taking digoxin (25% vs. 47%, p = 0.001). The mean age of patients taking digoxin (n: 78) was 63.7 ± 12.4 years, among which 64% were males. The mean age of the control group was 65.4 ± 11.8 years, among which 74% were males. However, there was no difference in mortality between the two groups (34% vs. 45%, p = 0.10). While Kaplan-Meier curves revealed no significant differences between mortality rates in the groups (log-rank p = 0.508), a statistical difference was found between the groups in rehospitalization rates (log-rank p =  0.013). A multiple linear regression analysis revealed that smoking (HR: 1.97, CI: 1.24-3.11, p = 0.004), systolic blood pressure (HR: 0.983, CI: 0.974-0.992, p < 0.001), atrial fibrillation (HR: 2.09, CI: 1.17-3.72, p = 0.012), C-reactive protein (CRP) (HR: 1.009, CI: 1.003-1.015, p = 0.004), beta-blockers (HR: 0.891, CI: 0.799-0.972, p = 0.009), angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (HR: 0.778, CI: 0.641-0.956, p < 0.001), mineralocorticoid receptor antagonists (HR: 0.41, CI:0.26-0.65, p < 0.001), and digoxin use (HR: 0.59, CI: 0.43-0.80, p = 0.001) are independent predictors of rehospitalization in patients with HFrEF.

CONCLUSIONS

Our results show that digoxin use does not affect mortality in HFrEF patients. However, rehospitalization decreased in patients taking digoxin in HFrEF.

Osteoimmunomodulatory GelMA/liposome coatings to promote bone regeneration of orthopedic implants

Despite being the most widely used biomaterials in orthopedic surgery, metallic implants do not induce new bone growth because they are bioinert. Surface biofunctionalization of implants with immunomodulatory mediators is a recent approach to promote osteogenic factors that facilitate bone regeneration. Liposomes (Lip) can be used as a low-cost, efficient and simple immunomodulator to stimulate immune cells in favor of bone regeneration. Even though liposomal coating systems have been reported previously, their main disadvantage is their limited ability to preserve liposome integrity after drying. In order to address this issue, we developed a hybrid system in which liposomes could be embedded in a polymeric hydrogel namely gelatin methacryloyl (GelMA). Specifically, we have developed a novel versatile coating strategy using electrospray technology to coat implants with GelMA/Liposome without using adhesive intermediate layer. The two differently charged Lip (i.e., anionic and cationic) were blended with GelMA and coated via electrospray technology on the bone-implant surfaces. The results showed that the developed coating withstood mechanical stress during surgical replacement, and Lip inside GelMA coating stayed intact in different storage conditions for a minimum of 4 weeks. Surprisingly, bare Lip, either cationic or anionic, improved the osteogenesis of human Mesenchymal Stem Cells (MSCs) by inducing pro-inflammatory cytokines, even at a low dosage of Lip released from the GelMA coating. More importantly, we showed that the inflammatory response could be fine-tuned by selecting the Lip concentration, Lip/hydrogel ratio, and coating thickness to determine the timing of the release such that we can accommodate different clinical needs. These promising results pave the way to use these Lip coatings to load different types of therapeutic cargo for bone-implant applications.

Association of serum proprotein convertase Subtilisin/Kexin Type 9 (PCSK9) level with thyroid function disorders

OBJECTIVE

We aimed at demonstrating the effect of thyroid function status on proprotein convertase subtilisin kexin type 9 (PCSK9) and determining the effect of thyroid hormones on lipid metabolism by comparing the PCSK9 levels of patients with subclinical hypothyroidism, overt hypothyroidism, and hyperthyroidism.

PATIENTS AND METHODS

124 patients with thyroid disorders, aged between 18 and 65 years, were included in this study. The participants were divided into 3 groups. Group 1 comprised 52 patients with subclinical hypothyroidism, Group 2 comprised 40 patients with overt hypothyroidism, and Group 3 comprised 32 patients with hyperthyroidism. In all of these groups, the thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglyceride, total cholesterol, fasting serum glucose, antithyroid peroxidase antibody, antithyroglobulin antibody, and PCSK9 levels were measured.

RESULTS

No significant difference was found between the 3 groups in terms of age, gender, and body mass indices. Median PCSK9 measurements were 14.55 ng/mL in Group 1, 14.895 ng/mL in Group 2, and 9.775 ng/mL in Group 3. There was a significant difference in the PCSK9 levels between Group 1-Group 3 and Group 2-Group 3 (p <0.0001 and p <0.0001, respectively). A positive correlation between PCSK9 and the TSH levels (r = 0.211, p= 0.019), and a negative correlation (r = -0,239, p = 0.009 and r = -, 0.218, p = 0.015) between the fT3 and fT4 levels were found.

CONCLUSIONS

The serum PCSK9 levels were shown to be associated with thyroid dysfunction. However, no relationship was observed between the serum PCSK9 level and thyroid autoantibody positivity, and obesity in this study.

The easy way of evaluating exocrine pancreatic insufficiency in type 2 diabetes : listen to the patients' complaints and look in their eyes!

BACKGROUND AND STUDY AIMS

The objective of this study is to determine the prevalence of exocrine pancreatic insufficiency (EPI) in diabetic patients, and to investigate whether there is a relationship between EPI and diabetes period, gastrointestinal complaints and other diabetic microvascular complications.

PATIENTS AND METHODS

A total of 93 participants, consisting of 57 type 2 diabetes patients and 36 healthy volunteers have been included in our cross-sectional study. Participants were questioned for abdominal complaints and weight loss. Fecal elastase-1 (FE-1) was determined in fecal spot samples received from participants. The relationship between EPI and blood glucose, HbA1c, and duration and complications of diabetes were investigated.

RESULTS

FE-1 levels were significantly lower in diabetic group compared to control group (p=0.007). The number of patients with FE-1 levels of <200μg/g were significantly higher in diabetic group (p=0.002). A statistically significant negative correlation was determined between FE-1 levels and the duration of diabetes (r= -0.453 p<0.001). FE-1 levels were significantly lower in patients with retinopathy (p= 0.014). In the post-hoc analysis, this difference was due to patients in the proliferative retinopathy group. A significant negative correlation was determined between the presence of retinopathy and FE-1 levels (r=-0.32, p=0.02). Abdominal pain and distension complaints were independent predictive factors that estimate EPI.

CONCLUSIONS

An important part of type 2 diabetes patients has EPI and it should be considered in diabetes patients upon abdominal pain and distension. Determination of proliferative retinopathy in the eye examination may also suggest an idea on the possible presence of EPI.

Miniaturized Multi Sensor Implant for Monitoring of Hemodynamic Parameters

t a novel miniaturized multi sensor implant for monitoring hemodynamic parameters in cardiovascular regions. Pressure measurements are performed with a highly accurate capacitive pressure sensor. An additional acceleration and temperature sensor allows compensating the impact of patient's inclination and temperature variations on the pressure measurement, respectively. A multi-functional transponder application-specific integrated circuit (ASIC) manages sensor signal processing, storage of ID, sensor calibration data, telemetric energy, and data transmission with an extracorporeal reading unit. Each component of the implant is assembled on a low temperature co-fired ceramics (LTCC) circuit board with an integrated antenna coil enabling an inductive near-field coupling at a frequency of 13.56 MHz. For a streamlined shape and reduction of thrombogenicity, the implant is encapsulated by biocompatible polymers.

Mixed fungaemia: an 18-year report from a tertiary-care university hospital and a systematic review

BACKGROUND

While fungaemia caused by two or more different species of yeasts (mixed fungaemia, MF) is infrequent, it might be underestimated.

AIMS

This study aimed to determine the incidence of MF, clinical characteristics of the patients, and antifungal susceptibility profiles of the isolates with a systematic review of the literature.

SOURCES

Data sources were PubMed and Scopus.

STUDY ELIGIBILITY CRITERIA

Studies reporting ten or more mixed fungaemia episodes.

CONTENT

Study included MF episodes in adults between January 2000 and August 2018 in Hacettepe University Hospitals, Turkey. The isolation, identification and antifungal susceptibility testing (AFST) of the isolates were by standard mycological methods. Patient data were obtained retrospectively. Literature search was performed using relevant keywords according to PRISMA systematic review guidelines. A total of 32 patients with 33 MF episodes were identified. Among all fungaemia episodes, MF incidence was 3.7% (33/883). All patients had one or more underlying disorders among which solid-organ cancer (50.0%, 16/32) was the most common. Overall mortality was 51.5% (17/33). The most preferred antifungal agents for initial treatment were fluconazole (48.5%, 16/33) and echinocandins (39.4%, 13/33). Fluconazole susceptible-dose-dependent (S-DD) or -resistant Candida species were detected in 15 episodes, and an isolate of C. parapsilosis was classified as S-DD by AFST. All Candida isolates were susceptible to echinocandins. Non-candida yeasts with intrinsic resistance/reduced susceptibility to both echinocandins and fluconazole were detected in two episodes. Systematic review of the literature revealed 24 studies that reported more than ten MF episodes. Methodology was variable. Improvement of detection rates was reported when chromogenic agars were used. Most studies underlined detection of isolates with reduced susceptibility.

IMPLICATIONS

Although rare, the MF rate is affected by the detection methods, which have improved in recent years. Fluconazole and echinocandins were used for initial treatment in accordance with the current guideline recommendations; however, isolates non-susceptible to both were detected. Detection of a mixed infection offers an opportunity for optimum treatment.

Using plasma exchange to successfully manage thyrotoxicosis in a patient with possible antithyroid drug-related thrombotic thrombocytopenic purpura

OBJECTIVE

Thrombotic thrombocytopenic purpura (TTP) is a rare disease characterized by microangiopathic hemolytic anemia, thrombocytopenic purpura, neurologic abnormalities, fever, and renal insufficiency. The association or co-existence of thyrotoxicosis or antithyroid drugs with TTP has not been previously reported. Subject and Results. Herein, we present a 54-year-old female patient newly diagnosed with toxic multinodular goiter accompanying with TTP, possibly triggered by either thyrotoxicosis or antithyroid drugs.

CONCLUSIONS

The present report is the first in the literature to demonstrate the co-existence of these two diseases and the use of plasma exchange as a modality to treat both conditions.

Genetic heterogeneity within the HLA region in three distinct clinical subgroups of myasthenia gravis

This study aims to investigate genetic susceptibility to early-onset and late-onset anti-acetylcholine receptor antibody positive myasthenia gravis (EOMG and LOMG) and anti-muscle specific kinase antibody positive MG (MuSK-MG) at genome-wide level in a single population. Using a custom-designed array and imputing additional variants and the classical HLA alleles in 398 patients, we detected distinct associations. In EOMG, rs113519545 in the HLA class I region (OR=5.71 [3.77-8.66], P=2.24×10(-16)), HLA-B*08:01 (OR=7.04 [3.95-12.52], P=3.34×10(-11)) and HLA-C*07:01 (OR=2.74 [1.97-3.81], P=2.07(-9)), in LOMG, rs111256513 in the HLA class II region (OR=2.22 [1.59-3.09], P=2.48×10(-6)) and in MuSK-MG, an intronic variant within HLA-DQB1 (rs68081734, OR=5.86, P=2.25×10(-14)) and HLA-DQB1*05:02 (OR=8.56, P=6.88×10(-13)) revealed the most significant associations for genome-wide significance. Differential genetic susceptibility within the HLA to EOMG, LOMG and MuSK-MG has been established in a population from Turkey.

Systemic Rituximab Immunotherapy in the Management of Primary Ocular Adnexal Lymphoma: Single Institution Experience

PURPOSE

To evaluate the efficacy of systemic rituximab immunotherapy in the management of primary ocular adnexal lymphomas (OAL).

MATERIALS AND METHODS

Clinical records of 10 consecutive patients (11 eyes) with biopsy-proven OAL managed with systemic anti-CD20 monoclonal antibody (rituximab; 375 mg/m(2) intravenously once every three weeks for 6-8 cycles) between June 2008-March 2013 were evaluated retrospectively. Orbital magnetic resonance imaging and positron emission tomography were performed to evaluate any orbital and systemic involvement, respectively. Clinical response was classified as complete or partial.

RESULTS

The age of patients ranged between 27-85 (median, 55) years. Nine patients (90%) presented with unilateral and one (10%) with bilateral conjunctival involvement. Orbit was affected in 4 patients (40%), one of which had also choroidal involvement (10%). None of the patients had systemic involvement at initial presentation. All patients received an average of 7 cycles (range, 6-8) of systemic immunotherapy. After a median follow-up of 31 months (range, 10-61 months), complete response without recurrence could be achieved in 4 eyes (36%) with rituximab monotherapy. No systemic or ocular side effects were observed in any patient. Additional radiotherapy was required in 6 patients (7 eyes; 64%) with partial response or recurrence.

CONCLUSIONS

Complete regression of primary OALs without recurrence was observed in about one-third of eyes after systemic rituximab monotherapy. Adjunctive radiotherapy was required in remaining two-thirds of the cases to achieve complete response. Thus, considering the balance between high rate of local control and potential ocular complications of radiotherapy, systemic rituximab can be considered as a first-line therapeutic option in the management of primary OAL.

Non-Hodgkin lymphoma in children: Is 1 g/m2 methotrexate as effective as 5 g/m2 in advanced-stage nonlymphoblastic non-Hodgkin lymphoma?

10043

Background: Survival rates in non-Hodgkin lymphoma (NHL) have increased significantly in the last decades. This study aims to assess the demographic data and treatment results of children with nonlymphoblastic NHL treated in a single institution. Methods: 106 children (74 male, 32 female), treated in Istanbul University, Oncology Institute, between 9/1989-12/2012 were evaluated retrospectively. Nonlymphoblastic NHL received COMP until 1991. After then, all received BFM protocols. They received BFM 90 protocol with 5 g/m2 methotrexate (MTX) until 1995 and modified BFM protocol with 1 g/m2 MTX thereafter. Results:The median age was 8(2-19) years. Histopathologic subtypes: 81 Burkitt, 25 large cell. The primary location was abdomen in 51, mediastinum 4, head/neck 31, 20 other (bone 8, breast 2, ovaries 2, skin 2, paravertebral 2, other 4). Bone marrow was involved in 10, CNS in 2. 40 patients had stage I+II, 44 stage III, and 22 stage IV disease. 23 patients died, 7 due to toxicity, 2 with second malignancies (AML,GBM). 10 year survival and EFS in the whole group was 76 and 76 % respectively. 10 year survival was 100, 94.3, 71.3 and 50% in stage I, II, III, and IV. In advanced stage nonlymphoblastic NHL patients, 10 year survival was significantly higher in patients receiving BFM regimen with 1 g/m2 MTX, than in ones receiving COMP or BFM protocol with 5 g/m2 MTX (10 year S, 81%, 46.7%, 44.4% respectively). These results were also compared with 47 advanced stage nonlymphoblastic NHL patients treated with 5 g/m2 BFM protocol in another center in the same university in the same time period (5 year S 78 %). Conclusions: Survival rates in the whole group are in parallel with advances attained in the world in NHL. The significantly higher survival rates achieved in patients with advanced stage non-lymphoblastic patients receiving modified BFM (1g/m2MTX) may be due to the decreased toxicity seen in this group and to the advances in supportive care in the last decade. In another major center in the same university that used the same protocol with 5 g/m2 MTX in the same time period, similar survival rates suggest that 1 g/m2 MTX which is cheaper and less toxic is also as effective as 5 gr/m2 in these patients.

Peritoneal seeding and subsequent progression of mantle cell lymphoma after splenectomy for debulking

BACKGROUND

Peritoneal seeding after abdominal surgery is a well known route of metastasis in intra-abdominal solid tumours. Direct mechanical contamination, local peritoneal trauma and subsequent inflammation, postoperative immunosuppression, and laparoscopic surgery are the proposed predisposing factors for this type of metastasis. These factors probably result in enhanced adhesion or growth of tumour cells. However, this route of metastasis has not yet been reported for lymphomas. Here, we report the first case of peritoneal seeding of lymphoma cells after an abdominal surgery.

CASE DESCRIPTION

A 47-year-old man with mantle cell lymphoma had ascites because of infiltration of the liver. He underwent debulking splenectomy. The postoperative ascites cytology and control abdominal computed tomography imaging both confirmed peritoneal involvement and lymphoma progression. Demonstration of negative peritoneal involvement before surgery and close timing of peritoneal involvement after splenectomy suggested to us that the debulking surgery was the main cause of peritoneal seeding of lymphoma cells in our case.

CONCLUSIONS

Factors similar to those in solid tumour seeding may also be valid for lymphomas. Peritoneal seeding and consequent disease progression may be a potential complication of abdominal surgery in lymphoma with extensive intra-abdominal involvement.

Diagnosis in childhood abdominal Burkitt's lymphoma

BACKGROUND

The role of surgery has changed substantially over the years in abdominal Burkitt's lymphoma. Laparotomy without total excision of the tumor does not have a positive effect on survival, might cause complications, and delays initiation of chemotherapy. Here we present our diagnostic management of patients with abdominal Burkitt's lymphoma.

MATERIALS AND METHODS

The diagnostic methods of abdominal Burkitt's lymphoma cases treated between January 1999 and December 2009 were evaluated retrospectively.

RESULTS

Of the 48 abdominal Burkitt's lymphoma patients, 13 also had extra-abdominal site involvement. Diagnosis was made with ultrasound-guided tru-cut needle biopsy of the abdominal mass (n = 11), fluid cytology (n = 7), extra-abdominal site biopsy (n = 4), bone marrow aspiration (n = 2), gastroscopy (n = 1), and laparotomy (n = 23). In patients diagnosed with laparotomy, chemotherapy was started in 4-22 days (median 7) compared with patients diagnosed with other diagnostic interventions in 2-4 days (median 2) (P < .001).

CONCLUSION

Although the most frequently used technique is laparotomy and open biopsy in our series, other methods provided quicker initiation of chemotherapy and less surgical morbidity. Especially in patients with high stages, cytological evaluation and tru-cut needle biopsy with radiological guidance is a better alternative of laparotomy.

Li-Fraumeni syndrome in a Turkish family

Li-Fraumeni syndrome (LFS) is one of the familial cancers characterized by different tumors and hereditary TP53 mutations. The adrenocortical carcinoma (ACC) association with acute leukemia is unusual in childhood, even in LFS. The authors here present a family with pR337P mutation in TP53 gene who had a child with acute lymphoblastic leukemia (ALL) and associated adrenocortical carcinoma as a case 1 and his cousin with brain tumor as a case 2. A hereditary TP53 mutation supported the diagnosis of LFS in this family. The patients had many difficulties in treatment strategies and succumbed to death. The availability of a reliable molecular marker to detect the R337P TP53 mutation allows the rapid identification of carriers in families that have a child with ACC. Once identified, carriers could be screened for early detection of ACC by imaging and endocrine studies and should be given psychological support to prevent anxiety for death. Whether early detection of ACC will reduce the mortality in these patients remains to be determined.

Mucosa-associated lymphoid tissue lymphoma of the duodenum together with multiple intra-abdominal thromboses and hepatitis C virus infection: a case report

Mucosa associated lymphoid tissue MALT lymphoma is a low grade malignancy that arises most commonly from the gastric mucosa. Small intestinal involvement is very rare. The causative relationship between Helicobacter pylori and the gastric MALT lymphoma is a well known issue, but recently there are several data suggesting the role of hepatitis C virus (HCV) infection in the pathogenesis of lymphoma including MALT lymphoma. Herein we present a rare case of duodenal MALT lymphoma with multiple intra-abdominal thromboses together with HCV infection that was confirmed by real-time polymerase chain reaction detecting HCV-RNA within the peripheral blood mononuclear cells.

T-Cell Lymphoblastic Lymphoma Presenting with a Breast Mass

Lymphomas secondarily involving the breast are uncommon, although they do represent the largest group of tumors metastatic to breast. A 20-year-old female with lymphoblastic lymphoma (LBL) presented here with 3 month history of weight loss, night sweats, fatigue and a mass in her left breast. Her physical examination revealed a left breast mass, lympadenopathy, bilateral pleural effusion and hepatomegaly. WBC count was 17,710/mm3 and LDH was mildly elevated. Breast ultrasound showed a 1.7 cm mass in the inner lower quadrant of left breast. Biopsy of the breast mass showed diffuse infiltration with small, round atypical cells which did not stain with CD20, CD43, CD34, cytokeratine and were positive for CD3. She was diagnosed as leukemic phase of a precursor T-cell LBL and treated with 6 cycles of CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone), intrathecal methotrexate and cranial radiotherapy, achieving a complete response. She then was started on maintenance therapy. Four months later she returned with CNS involvement and was started on induction treatment. She had a very aggressive course of disease and died only 12 months after diagnosis. Breast involvement is very rarely seen in precursor T-cell LBL/ALL and in this patient occurred secondarily as part of widespread disease.

Caffeic acid phenethyl ester prevents ovary ischemia/reperfusion injury in rabbits

Protective effect of caffeic acid phenethyl ester (CAPE) on ovary ischemia/reperfusion (IR) injury was investigated in this study. Twenty four New Zealand rabbits were divided into 4 groups as follows: group S served as sham. Group C was intraperitoneally injected with CAPE (8.5mg/kg). In groups E+IR and C+IR, 1% ethanol and CAPE was given intraperitoneally before torsion, respectively. Then, the ovaries were subjected to IR in both groups. Ovary reduced glutathione (GSH) level and glutathione peroxidase (GSH-Px) activity in group E+IR were significantly reduced compared to that of group S. GSH level and GSH-Px activity was significantly increased in group C+I/R. Thiobarbituric acid reactive substances (TBARS) and catalase (CAT) activity in group E+I/R was significantly higher than in group S. CAT activity was decreased to normal levels by CAPE treatment in group C+I/R, while TBARS in group C+IR was significantly reduced compared to that of E+IR. According to histopathological examination, severe congestion, hemorrhage, edema and leukocyte infiltration were observed in E+I/R group. CAPE prominently reduced degenerative effects of IR injury thus it alleviates free radical damage. In conclusion, CAPE which is able to prevent IR-induced injury in the ovaries may be of therapeutic value before the surgical correction.

The effects of physical exercises to mental state and quality of life in patients with schizophrenia

The purpose of this study was to examine the effects of 10 weeks of physical exercises programme on mental states and quality of life (QOL) of individuals with schizophrenia. The study involved 30 inpatients or outpatients with schizophrenia who were assigned randomly into aerobic exercise (n = 15) group and control (n = 15) group, participated to the study voluntarily. There were no personal differences such as age, gender, disorder duration, medication use between the both groups. An aerobic exercise programme was applied to the subject group, the periods of 10 weeks as 3 days in a week. Data were collected by using the Brief Symptom Inventory, the Scale for the Assessment of Positive Symptoms, the Scale for the Assessment of Negative Symptoms and to the both group before and after the exercise programme. After the 10-week aerobic exercise programmes the subjects in the exercise programme showed significantly decreases in the Scale for the Assessment of Positive Symptoms, the Scale for the Assessment of Negative Symptoms and the Brief Symptom Inventory points and their World Health Organization Quality of Life Scale-Turkish Version points were increased than controls. These results suggest that mild to moderate aerobic exercise is an effective programme for decreasing psychiatric symptoms and for increasing QOL in patients with schizophrenia.

Psychiatric morbidity in murder and attempted murder crime convicts: A Turkey study

In the present, the morbidity of psychiatric disorders of homicide/attempted homicide crime convicts imprisoned in Turkey, Sivas maximum security prison was investigated. Seventy imprisoned homicide/attempted homicide crime convicts included in this study. Sociodemographic information form, structured clinical interview for DSM-IV Axis-I disorders and structured clinical interview for DSM-III-R personality disorders applied to the participants. Most commonly diagnosed disorders among those convicts were current Axis-I disorders, depressive disorders (7.1%) and anxiety disorders (5.7%). Among Axis-I disorders, the most diagnosed one was the substance use disorders (45.7%). The most diagnosed Axis-II disorder was found as to be antisocial personality disorder (48.6%). The rate of convicts who were diagnosed as having both Axis-I and Axis-II disorders was 51.4%. The most prevalently accompanying lifetime Axis-I disorders to antisocial personality disorder with respect to Axis-I, and Axis-II comorbidity was substance use disorders. As a result, it was thought that the substance use disorders and antisocial personality disorder among the homicide/attempted homicide crime convicts were the most prevalent lifetime psychiatric disorders.

T-cell-rich B-cell lymphoma of the spleen presenting with severe hypersplenism

We report a 19-year-old woman who was presented with B-symptoms, massive splenomegaly, hepatomegaly and hypersplenism. She underwent diagnostic/therapeutic splenectomy. Microscopically, the spleen showed a vaguely micronodular and diffuse proliferation of lymphoid cells in the white pulp that also involved the red pulp. On immunohistochemical staining, this proliferation consisted predominantly of CD3(+), CD7(+) small T cells with the presence of a minor population of CD15(-),CD30(-), CD20(+) large atypical B cells. A liver biopsy also showed a similar morphology to that seen in the spleen. After splenectomy, only the pancytopenia improved. A combined immunochemotherapy regimen (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone) was utilized, which resulted in a complete remission.

Identification of a morphometrical parameter that predicts the response to splenectomy in patients with idiopathic thrombocytopenic purpura

Idiopathic thrombocytopenic purpura (ITP) is an isolated thrombocyte disease that has no correlation with other causes of clinical thrombocytopenia in adults. About 70% of patients with ITP were successfully treated by medical care and splenectomy, but nearly 30% of ITP patients do not respond to these treatments. The aim of this study is to evaluate the predictive factors that affect the success of treatment in 26 patients with ITP. Thirteen patients with ITP responded to splenectomy (responsive group), whereas 13 other patients were resistant to medical treatment and splenectomy (resistant group). The control group consisted of 13 patients who had undergone posttraumatic splenectomy. Age, sex, spleen weight, the number of follicles per mm(2), and the length of time between diagnosis and splenectomy were retrospectively analyzed. No significant difference was found between the groups with respect to these variables. Mean maximum follicle diameter (MMaFD), mean minimum follicle diameter (MMiFD), and the number and distribution of CD56 (+) cells were evaluated for each spleen specimen. There was no statistical difference in the distribution of CD56 (+) cells between the ITP patients and the control group, but the number of CD56 (+) cells was significantly higher in the control group than in patients with ITP. While MMiFD showed no statistical difference between the groups of ITP patients, a MMaFD of 350 microm and above was significantly more likely in the resistant group than in the other groups. In conclusion, this study has shown that the MMaFD is a significant predictor of the response to splenectomy.

The value of tartrate resistant acid phosphatase (TRAP) immunoreactivity in diagnosis of hairy cell leukemia

Hairy cell leukemia (HCL) is a rare chronic B-cell lymphoproliferative disorder characterized by splenomegaly, pancytopenia, and circulating atypical lymphocytes with circumferential cytoplasmic projections. We investigated the specificity and the sensitivity of anti-TRAP antibody immunoreactivity in 57 cases of HCL. We found that there is a statistically highly significant difference between TRAP immunoreactivities of the study and the control groups, and HCL can be diagnosed by TRAP immunoreactivity in bone marrow trephine biopsy materials with a specificity of 98.27 % and a sensitivity of 100%.
