Haematological manifestations in primary hyperparathyroidism.

Background & objectives: Primary hyperparathyroidism (PHPT) is a common endocrine disorder caused by the elevated secretion of the parathormone (PTH). The aim of this study was to evaluate the haematological manifestations of PHPT in patients with normal renal functions who were treated surgically for parathyroid adenomas. Methods: In this retrospective cross-sectional study, 134 patients with normal renal functions who underwent parathyroidectomies for PHPT were included. The haematological manifestations were evaluated in the total study cohort and in the two groups of different calcium (Ca) levels (Group 1 ≤11.2 mg/dl and Group 2 >11.2 mg/dl). Results: The overall prevalence of anaemia, leucopenia and thrombocytopenia was 20.1, 6.7 and 6.0 per cent, respectively. Normocytic anaemia was present in 19 (14.2%) patients. There were no significant differences in the prevalence of anaemia, leucopenia and thrombocytopenia between the two groups. There were no correlations between the PTH levels and the leukocyte, haemoglobin or platelet values. Six to 12 months after the parathyroidectomy (PTX), 35.7 per cent of the patients with anaemia, 85.7 per cent of the patients with leucopenia and 100 per cent of the patients with thrombocytopenia had recovered. Interpretation & conclusions: In the present study, anaemia was seen with a variable frequency in PHPT, but there was no relationship between anaemia and high PTH or Ca levels. The development of anaemia can be seen regardless of the PTH levels in PHPT patients with normal renal functions. High-resolution rates after PTX indicate a possible association between PHPT and thrombocytopenia or leucopenia, although their prevalence is low in PHPT.

Prevalence of Sleep Disorders and Related Factors in Individuals Undergoing Hemodialysis.

BACKGROUND: The quality of life of individuals undergoing hemodialysis is related to many factors, including sleep disorders. OBJECTIVE: To determine the prevalence of sleep disorders in individuals undergoing hemodialysis and to assess the effect of clinical and biochemical parameters on their sleep quality. METHOD: We conducted a cross-sectional descriptive survey in multiple hemodialysis centers. Individuals were interviewed using a questionnaire for obtaining general personal information, the Pittsburgh Sleep Quality Index (PSQI) for assessing sleep quality, and the Epworth Sleepiness Scale (ESS) for assessing excessive daytime sleepiness (EDS). RESULTS: The study included 338 individuals with a median age of 55 years. Poor sleep quality (PSQ) and EDS were present in 41.4% and 6.5% of the individuals, respectively. The individuals' PSQI scores were significantly proportional to their ESS scores. Concerns about the disease and its treatment (60.7%) and poor physical conditions (35.7%) were major reported reasons for PSQ. In a logistic regression analysis, female gender, household income, ESS score, chronic heart failure, and creatinine and parathormone levels were found to be independent predictors of PSQ; household income, PSQ presence, parathormone and potassium levels, and urea reduction ratio were found to be independent predictors of EDS. CONCLUSION: Sleep disorders are common in individuals undergoing hemodialysis and are related to gender, comorbid diseases, poor economic state, altered biochemical values, dialysis timing, and concerns about the disease and its treatment. Improving these individuals' quality of life through adequate psychological and financial support and early diagnosis of sleep disorders should decrease their mortality and morbidity rates.

Adult-onset still's disease and treatment results with tocilizumab.

AIMS: Adult-onset Still's disease (AOSD) is a rare and non-familial auto-inflammatory disorder. Increased levels of IL-6 and other pro-inflammatory cytokines have been shown in AOSD. To evaluate the efficacy and safety profile of tocilizumab (TCZ), an IL-6 receptor antagonist monoclonal antibody, in AOSD. METHODS: Thirty-nine patients followed up with the diagnosis of AOSD between 2013 and 2019 were retrospectively evaluated and the 16 patients (10 Female/6 Male) treated with TCZ for refractory AOSD were included in the study group. Among the remaining 23 patients 16 had non-biological treatments and had no important complications at the presentation. TCZ was given to patients at a dose of 4-8 mg/kg every 4 weeks. Patients were evaluated after 3-6 months of TCZ treatment for side effects, inflammatory and clinical response and concomitant treatments. RESULTS: In TCZ (+) patients, the majority were female (62.5%), the mean age at disease onset was 38.5 ± 17.9 (20-81) years, and the most common symptoms and signs were myalgia (81.3%), fever (81.3%) and skin eruptions (75%). There was no difference between TCZ (+) and TCZ (-) groups for age, sex and clinical presentations. There was a significant decrease in dose of prednisolone, sedimentation rate, leucocyte count, C-reactive protein and ferritin levels and improvement in all clinical complaints after TCZ treatment. There were no relapses during the treatment. Three patients are in remission and under follow-up without any treatment after cessation of TCZ (4 months-3 years). No exacerbation of disease yet seen in those patients. CONCLUSIONS: TCZ is an effective and well-tolerated treatment option for treatment resistant AOSD and contributes to the glucocorticoid-sparing. Since TCZ is a new drug in the treatment of AOSD, further studies are needed to assess whether the complications reported during the treatment are because of TCZ or natural course of the disease or coincidental findings.

Evaluation of Hepatitis B screening and reactivation in patients receiving rituximab containing chemotherapy: A single-centre study.

AIMS: Hepatitis B virus (HBV) infection is a worldwide distributing viral disease. Hepatitis caused by HBV reactivation may progress to chronic illness and associated with increased risk of hepatic failure and hepatocellular cancer. Rituximab (RTX) is an immunosuppressive agent, is particularly used in the treatment of non-Hodgkin's Lymphoma. Patients have significant risk for HBV reactivation following chemotherapy with a RTX-containing regimen. This study aimed to determine the HBV screening manner and reactivation rates in patients with haematological neoplasm following chemotherapy including Rituximab. METHODS: This is a single-centered retrospective cohort study. A total of 331 adults with haematological disorders who received chemotherapy regimen including RTX between years of 2006 and 2016 were enrolled. Patients who experienced reactivation were evaluated. RESULTS: Only 130 of 331 patients were screened appropriately for HBV infection for 10-year period. We found 18 patients were Hepatitis B surface antigen (HBsAg) (+) and 16 (88.8%) of them received antiviral prophylaxis. Among screened patients, 27 were HBsAg (-)/AntiHBc (+) and only 10 (37%) of them received HBV prophylaxis. In total, nine patients experienced reactivation, six were from screened and three were from unscreened group. CONCLUSION: Incomplete screening and inappropriate prophylaxis may result in HBV reactivation in patients under RTX-based chemotherapy and related complications such as death.

Effects of preoperative calcium levels and parathyroidectomy on renal function in primary hyperparathyroidism: a retrospective study.

AIM: TTo assess the effects of preoperative calcium levels and parathyroidectomy on estimated glomerular filtration rate (eGFR) in patients of primary hyperparathyroidism (PHPT) with mild renal dysfunction or normal renal function. METHODS: This retrospective study enrolled 71 patients who underwent parathyroidectomy for PHPT in the General Surgery Department at Ondokuz Mayis University Hospital from 2010 to 2018. All patients were histopathologically diagnosed with parathyroid adenoma. Total serum calcium, serum creatinine, serum intact parathyroid hormone (PTH), and serum 25-hydroxyvitamin D3 (25(OH)D3) were measured before and 3-6 months after surgery. Patients were assigned to the low eGFR group (60-90 mL/min/1.73 m2) or normal eGFR group (≥90 mL/min/1.73 m2) and to the low calcium group (≤11.2 mg/dL) or high calcium group (>11.2 mg/dL). RESULTS: In the low eGFR and high calcium group, there were significantly more patients with hypertension and older age. In the normal eGFR and high calcium group, eGFR was significantly reduced after surgery. Independent predictors of eGFR change after surgery were age, pre- parathyroidectomy calcium, and pre-parathyroidectomy eGFR. CONCLUSIONS: After surgery, patients with low eGFR had preserved renal function, whereas those with normal eGFR had decreased renal function. Mild renal dysfunction in PHPT was associated with older age, hypertension, and high calcium levels.

Relationship between metabolic syndrome and nodular thyroid diseases.

Nodular thyroid diseases are common in Turkey. Insulin resistance (IR) is considered as the most important component of metabolic syndrome (MetS), and it is thought to directly affect thyroid diseases, together with other components of MetS. The aim of this study was to evaluate potential factors associated with thyroid nodularity. This study was part of the prospective MELEN study. In total, randomly selected 2233 subjects were evaluated. A euthyroid subgroup of participants (n = 1432) was selected and 421 of them had MetS. Both goitres and multinodular goitres (MNGs) were significantly more common in the MetS (+) group (p < .001). Older age was the only factor that significantly affected the presence of a nodular goitre (NG) (p < .001). The presence of a MNG was associated with older age (p < .001), systolic blood pressure level (p < .008) and MetS (p < .001). There was no difference in the thyroid volume or presence of nodular thyroid diseases between the IR (+) and (-) groups. Both the thyroid volume and the presence of MNGs were significantly associated with MetS, independent of thyroid-stimulating hormone (TSH) and IR. We suggest that the individual components of MetS may influence thyroid nodularity to some degree and that together they exert a cumulative effect on the thyroid gland. As a result, in the absence of MetS, we further suggest that IR alone does not explain the increase in thyroid volume and thyroid nodule formation.

Rheumatoid arthritis masquerading as acromegaly recurrence: report of two cases.

Acromegaly is a chronic endocrinopathy characterized by hypersecretion of growth hormone (GH) and consequently of insulin-like growth factor-1 (IGF-1). The arthropathy in acromegaly is the most frequent and important cause of morbidity and functional disability in acromegaly. Rheumatoid arthritis (RA) is a rarely reported clinical situation in patients with acromegalic. We herein report 57- and 45-year-old two women, who complained bilateral, symmetric pain, swelling and morning stiffness in the joints of hands after optimal acromegaly treatment resembling acromegaly arthropathy. There was not arthralgia in other joints of the patients. Laboratory and radiological evaluations were carried out. After excluding the acromegaly activation and arthropathy by GH and IGF-1 measurement, according to clinical presentation, laboratory and radiological assessments, patients were diagnosed as RA.

Comparison of Energy Expenditure in Mechanically Ventilated Septic Shock Patients in Acute and Recovery Periods via Indirect Calorimetry.

BACKGROUND: Nutrition in intensive care units (ICUs) affects morbidity and mortality. We aimed to evaluate the energy expenditure of mechanically ventilated patients in early and late septic shock periods. METHODS: This study retrospectively evaluated 28 mechanically ventilated septic shock patients (11 female/17 male) in a medical ICU. Indirect calorimetry (IC) measurement was performed for 24 hours during the acute and recovery periods of septic shock. The energy values calculated by Harris-Benedict equation (predicted resting energy expenditure [PREE]), measured by IC (measured resting energy expenditure [MREE]), and given to each patient were obtained in the acute and recovery periods. RESULTS: The mean age was 67.46 ± 14.92 (36-91) years. The MREE was 2741.1 ± 706.3 kcal/d (38.61 ± 11.44 kcal/kg/d) and 2332.8 ± 426.6 kcal/d (32.65 ± 7.8 kcal/kg/d) in the acute and recovery periods, respectively, and showed significant differences (P = 0.001). The patients' energy intake was 1152.7 ± 207.1 kcal/d and 1542.7 ± 433.3 kcal/d in the acute and recovery periods, respectively. A significant difference existed between energy intake and MREE during the acute and recovery periods (P < 0.001 for both). CONCLUSION: Our findings showed that energy expenditure increases in septic shock. Significant differences existed between MREE, PREE, and energy intake, which were not correlated. The MREE was higher in the acute period. Despite the increasing energy requirement, the PREE and energy intake were well below MREE. For better clinical outcomes, each patient's energy expenditure must be closely monitored and evaluated using intermittent IC measurements.

Self-reported practices of doctors and nurses for the measurement of blood pressure.

BACKGROUND: Hypertension is one of the most common health problems worldwide and can be diagnosed with an accurate blood pressure measurement (BPM). We aim to evaluate the self-reported practices of family physicians and nurses for BPM. METHODS: This study was conducted in the form of a survey administered through face-to-face interviews with 131 physicians and 371 nurses. The survey included questions about devices, patients, and BPM techniques. RESULTS: The mean age was 31 ± 7.4 years. The most commonly used device was the aneroid model (47.8%). The majority of participants reported that they had sufficient technical knowledge about the devices (81.1%), and the devices were regularly calibrated (77.5%). Only 44.8% reported that they had asked patients about caffeine or nicotine use. About half of those in both groups (54%) performed BPM only once during a presentation. The most commonly used position during BPM was sitting. BPM was performed mostly on one arm without preference for any side (67.5%). Approximately half of the respondents reported that they performed BPM by actively supporting the arm at the heart level. CONCLUSION: We found physicians and nurses had lack of adherence to proper techniques related to the use of appropriate positions and other relevant situations that should be considered during BPM. Accurate BPM is the most important factor for proper diagnosis and treatment of hypertension. Thus, BPM should be performed in accordance with the designated guidelines and can be performed with accurate results only as a result of repeated comprehensive training programs.

Age is not a risk factor in survival of severely ill patients with co-morbidities in a medical intensive care unit.

BACKGROUND: The individuals over 65 years old constitute an important patient population of medical intensive care units (ICUs). AIM: To evaluate the risk factors for mortality in a medical ICU consisting a group of patients with a large number of co-morbidities. METHODS: This is a retrospective study involving patients who were followed for more than 48 h. The cohort was divided into two groups according to age: (1) young, < 65 years old, and (2) elderly, ≥ 65 years old. RESULTS: A total of 693 patients (303 F, 390 M) were included. The median age was 68 years (18-97). There were 279 (40.3%) young and 414 (59.7%) elderly patients. There was no difference between the groups in gender and mortality (p = 0.436, p = 0.932, respectively). Most of the co-morbid diseases were more common in the elderly except solid malignancies which were more common in young patients (p = 0.033). Long ICU stay, long hospital stay before ICU, high APACHE II and Charlson co-morbidity index scores, pneumonia, acute hepatic failure/coma, malignancy, acute hemodialysis, need for vasopressors, and invasive mechanical ventilation were independent predictors of ICU mortality. CONCLUSION: Age and gender were not found to be predictors of mortality. There was no survival advantage between young and elderly patients. Co-morbid diseases, apart from malignancy, had no effect on mortality. In developing countries, where patients with terminal illness and multiple co-morbid diseases are treated in the ICU, age should not be a determining factor in patient selection for ICU or in the treatment decisions to be applied to patients.

The diagnostic value of 4D MRI at 3T for the localization of parathyroid adenomas.

PURPOSE: The aim of this study was to assess the feasibility of four-dimensional magnetic resonance imaging (4D MRI) at 3 T for the localization of parathyroid adenomas. MATERIALS AND METHODS: Preoperative 4D MRI scans, encompassing dynamic contrast-enhanced (DCE) sequences and non-contrast enhanced (non-CE) sequences, including a T2-weighted multipoint Dixon (T2-mDixon) sequence, with in-phase, out-phase, and water-only images, were evaluated retrospectively in 41 patients with surgically proven parathyroid lesions. Two readers who were blinded to the surgical findings independently reviewed the images in two sessions (non-CE sequences alone and non-CE + DCE sequences). The MRI localization of the suspected adenoma in each session and the consensus interpretation of the MRI images, were compared with the surgical results and interobserver agreement was assessed. RESULTS: By interpreting the non-CE sequences alone, reader 1 correctly localized 34 parathyroid lesions (sensitivity 81.0%, positive predictive value (PPV) 87.2%), and reader 2 correctly localized 34 parathyroid lesions (sensitivity 81.0%, PPV 91.9%). With the addition of DCE sequences, reader 1 correctly identified 35 parathyroid lesions (sensitivity 83.3%, PPV 87.5%), while reader 2 correctly identified 36 parathyroid lesions (sensitivity 85.7%, PPV 92.3%). Overall, MRI detected 38 parathyroid lesions (sensitivity 90.5%, PPV 95.0%). Interobserver agreement was slightly superior in non-CE + DCE sequences compared to non-CE sequences alone (ĸ = 0.796 vs. ĸ = 0.738). CONCLUSION: 4D MRI with DCE sequencing is a reliable method for the localization of parathyroid adenomas.

Ptosis and Mass Like Lesions in Behçet's Disease: A Rare Presentation.

In this article, we describe a case of neuro-Behçet's disease presenting with unilateral ptosis and facial paresis due to an intracranial mass lesion. A 25-year-old male patient with a history of Behçet's disease presented with headache, vertigo, double vision, ptosis in his right eyelid and slurred speech. Cranial magnetic resonance imaging scan revealed a right-sided capsulothalamic lesion, which was extending to the right cerebral pedicle, pons and superior cerebellar pedicle. This lesion was interpreted as neuro-Behçet's disease involvement of central nervous system. Cerebral mass- like lesion is a rare form of neuro-Behçet's disease. Review of the literature revealed a limited number of cases. Ptosis related with Behçet's disease is also a very rare presentation. This case shows that this symptom might be a part of the clinical presentation of neuro-Behçet's disease.

The relationship between mean platelet volume with metabolic syndrome in obese individuals.

The metabolic syndrome is closely associated with atherosclerotic risk factors and increased mortality. Mean platelet volume (MPV) is an indicator of platelet activation which also shows a close relationship with cardiovascular risk factors, such as diabetes mellitus, hypertension, hypercholesterolemia, obesity, metabolic syndrome. The aim of this study was to investigate the correlates of metabolic syndrome, its components and MPV adjusted for obesity in a large population study. A total of 2298 individuals with a mean age of 50 (age range 18-92) were interviewed. Nine hundred and twenty obese participants, who had BMI 30 kg/m² or more, further evaluated for the presence of metabolic syndrome. Five hundred and thirteen [396 women (70.2%)] had metabolic syndrome and the rest 407 individuals [324 women (79.6%)] served as the control group. The BMI, SBP, DBP, waist circumference, fasting plasma glucose, visceral fat, total cholesterol, high-density lipoprotein-cholesterol, and triglyceride was higher significantly in metabolic syndrome group (P = 0.002 for BMI and P < 0.001 for the others). No significant difference was observed between groups regarding low-density lipoprotein cholesterol, white blood cells, platelet counts, MPV, hematocrit and hemoglobin (P > 0.05 for all). The presence of metabolic syndrome and its components do not constitute a difference in MPV values in obese patients with a BMI 30 kg/m² or more.
