COVID-19 outcomes in patients with antiphospholipid syndrome: a retrospective cohort study.

BACKGROUND: Aim of this study is to investigate COVID-19 outcomes in patients with antiphospholipid syndrome (APS). METHODS: A retrospective cohort was formed from APS patients. Patients were screened for a record of positive SARS-CoV 2 PCR. In PCR­positive patients, clinical data and information regarding COVID-19 outcomes were collected from medical records. RESULTS: A positive PCR test was detected in 9/53 APS patients, while 66.7 %, 33.3 % and 11.1 % of APS patients with COVID-19 were under hydroxychloroquine, LMWH or warfarin, and acetylsalicylic acid, respectively. There were 3/9 patients found to be hospitalized and one died. No new thrombotic event was reported in any of the patients during COVID-19 infection. CONCLUSION: Baseline use of hydroxychloroquine, antiaggregants and anticoagulants may be associated with an absence of new thrombotic event (Tab. 2, Ref. 33).

A case of Inappropriate Antidiuretic Hormone Secretion Syndrome Associated with COVID-19 Pneumonia.

At the end of 2019, a novel coronavirus was identified as the cause of a cluster of pneumonia in China and it spread quickly to other countries. Although Covid-19 causes severe pneumonia, it is known that it can be associated with different diseases and prognosis of disease can be due to many of disorders such as hyponatremia. A 65-year-old female patient with sarcoidosis, cronic obstructive lung disease, hypertension and congestive heart failure presented to the emergency department with shortness of breath and fever. Oropharyngeal swab for Covid-19 PCR test was positive. After the initiation of treatment, the patient developed hyponatremia. This case is remarkable because there is no reported case of Covid-19 and inappropriate ADH syndrome coexistence and it demonstrates that there may be a correlation between Covid-19 infection prognosis and hyponatremia.

Comparing immunoglobulin A vasculitis (Henoch-Schönlein purpura) in children and adults: a single-centre study from Turkey.

OBJECTIVE: Immunoglobulin A vasculitis/Henoch-Schönlein purpura (IgAV/HSP) is a systemic vasculitis involving small vessels with the deposition of immune complexes containing IgA. It is the most common primary systemic vasculitis of childhood and is much less common in adults. Our aim was to investigate the differences and similarities between adult and paediatric patients with IgAV/HSP. METHOD: We retrospectively evaluated the medical records of 35 adult and 159 paediatric (˂ 18 years old) patients with a clinical diagnosis of IgAV/HSP who were seen at the Departments of Rheumatology and Pediatric Rheumatology, Hacettepe University, Ankara, Turkey. The paediatric and adult patients were classified with IgAV/HSP according to the Ankara 2008 and American College of Rheumatology 1990 criteria, respectively. RESULTS: Upper respiratory tract infection was a common predisposing factor for both adults (34.3%) and children (21.4%). Creatinine and C-reactive protein were higher; and skin biopsy, hypertension, renal involvement, haematuria, proteinuria, and renal insufficiency at diagnosis were more frequent in adults than in children. Thrombocyte count was higher in children than in adults. Follow-up without treatment and complete recovery were more frequent in children, while persistent haematuria, chronic renal failure, relapse, and the use of corticosteroids/azathioprine were more frequent in adults. The only independent predictive factor for relapse was persistent haematuria. CONCLUSION: Various clinical and laboratory characteristics differ between children and adults with IgAV/HSP. Overall, IgAV/HSP has a self-limiting course in children but represents a more severe form of disease in adults, with more severe renal involvement. Persistent haematuria is a predictive factor for relapse.

Clinical and Laboratory Features of Metformin Intoxication in Suicidal Patients Attending an Intensive Care Unit.

INTRODUCTION: This study has been performed for the purpose of researching the complications occurred at patients who took metformin overdose in an attempt to suicide. None of the patients has the diagnosis of diabetes mellitus and never used metformin. MATERIALS AND METHODS: This retrospective cross-sectional study was carried out with 21 patients who has neither diagnosed diabetes mellitus nor taken metformin for suicide before. RESULTS: It was observed that there is a moderate, negative (r = -0.63) statistically significant correlation (P < 0.001) between the time of applying to the hospital and arterial blood pH at the arrival and a statistically significant positive mild correlation (P < 0.041) between applying and blood lactate level (r = 0.45), and a moderate positive (r = 0.63) and statistically significant correlation (P < 0.001) between the total metformin dose and blood lactate level at the arrival and a positive, moderate (r = 0.68) significant correlation (P < 0.001) between the creatinine and metformin dose at the arrival. Lactic acidosis has been detected at 8 of 21 patients, 6 patients were hemodialized, 2 patients needed mechanical ventilation, and 2 patients died. It is observed that there is no mortality for early hemodialized patients. CONCLUSION: The most important reason of the mortality in patients who has metformin intoxication is metformin-associated lactic acidosis (MALA). It was considered that hemodialysis therapy could be effective in MALA.

Assessment of the HScore for reactive haemophagocytic syndrome in patients with rheumatic diseases.

OBJECTIVES: Reactive haemophagocytic syndrome (RHS) is a hyperinflammatory disorder often occurring in the background of several disorders such as infections, malignancies, and rheumatic diseases. Recently, a score known as the HScore was developed for the diagnosis of RHS. In the original study, most of the patients had underlying haematological malignancy or infection and the best cut-off value for the HScore was 169 (sensitivity 93%; specificity 86%). In this study we aimed to analyse the performance of the HScore in rheumatic disease-related RHS. METHOD: The patients with rheumatic disorders evaluated in the Departments of Rheumatology and Paediatric Rheumatology at Hacettepe University, Ankara, Turkey between 2002 and 2014 were reviewed retrospectively. The first group (n = 30) consisted of patients with RHS; the control group (n = 64) included patients with active rheumatic diseases without RHS. RESULTS: In the RHS group, 14 (46.7%) had adult-onset Still's disease (AOSD), 10 (33.3%) systemic juvenile idiopathic arthritis (SJIA), and six (20%) systemic lupus erythematosus (SLE). The control group (n = 64) consisted of 32 (50%) AOSD, 13 (20.3%) SJIA, and 19 (29.7%) SLE patients. Applying the HScore to the RHS patients, the best cut-off value was 190.5 with a sensitivity of 96.7% and specificity of 98.4%. When we excluded the patients from the control group who had not had bone marrow aspiration (n = 23), the same cut-off (190.5) performed best (sensitivity 96.7%; specificity 97.6%). Applying the 2004 haemophagocytic lymphohistiocytosis (HLH-2004) criteria gave a sensitivity of 56.6% and a specificity of 100% in the whole study group. CONCLUSIONS: In our study, a cut-off value for the HScore different from the original study performed better. Further studies are warranted to determine optimum cut-off values in different studies.

Imaging of acute pancreatitis and its complications. Part 2: complications of acute pancreatitis.

The Atlanta classification of acute pancreatitis was introduced in 1992 and divides patients into mild and severe groups based on clinical and biochemical criteria. Recently, the terminology and classification scheme proposed at the initial Atlanta Symposium have been reviewed and a new consensus statement has been proposed by the Acute Pancreatitis Classification Working Group. Major changes include subdividing acute fluid collections into "acute peripancreatic fluid collection" and "acute post-necrotic pancreatic/peripancreatic fluid collection (acute necrotic collection)" based on the presence of necrotic debris. Delayed fluid collections have been similarly subdivided into "pseudocyst" and "walled of pancreatic necrosis". Appropriate use of the new terms describing the fluid collections is important for management decision-making in patients with acute pancreatitis. The purpose of this review article is to present an overview of complications of the acute pancreatitis with emphasis on their prognostic significance and impact on clinical management and to clarify confusing terminology for pancreatic fluid collections.

Imaging of acute pancreatitis and its complications. Part 1: acute pancreatitis.

Acute pancreatitis is an acute inflammatory disease of the pancreas that may also involve surrounding tissues or remote organs. The Atlanta classification of acute pancreatitis was introduced in 1992 and divides patients into mild and severe groups based on clinical and biochemical criteria. Recently, the terminology and classification scheme proposed at the initial Atlanta Symposium have been reviewed and a new consensus statement has been proposed by the Acute Pancreatitis Classification Working Group. Generally, imaging is recommended to confirm the clinical diagnosis, investigate the etiology, and grade the extend and severity of the acute pancreatitis. Ultrasound is the first-line imaging modality in most centers for the confirmation of the diagnosis of acute pancreatitis and the ruling out of other causes of acute abdomen, but it has limitations in the acute clinical setting. Computed tomography not only establishes the diagnosis of acute pancreatitis, but also enables to stage severity of the disease. Magnetic resonance imaging has earned an ever more important role in the diagnosis of acute pancreatitis. It is especially useful for imaging of patients with iodine allergies, characterizing collections and assessment of an abnormal or disconnected pancreatic duct. The purpose of this review article is to present an overview of the acute pancreatitis, clarify confusing terminology, underline the role of ultrasound, computed tomography and magnetic resonance imaging according to the proper clinical context and compare the advantages and limitations of each modality.

DiGeorge syndrome associated with left lung aplasia.

We report a patient with clinical and cytogenetic findings consistent with DiGeorge-velocardiofacial syndrome and aplasia of the left lung. To the best of our knowledge, this is the first reported case of DiGeorge-velocardiofacial syndrome associated with unilateral lung aplasia. Gadolinium enhanced three-dimensional magnetic resonance angiography demonstrated associated right-sided aortic arch and left pulmonary artery agenesis.

Post-traumatic intradiploic epidermoid cyst. A case report.

A patient with an intradiploic epidermoid cyst of calvarium was presented. Head injury that may cause the inclusion of epidermal cells into the diploe of the bone was present in his medical history. Skull radiographs and cranial magnetic resonance imaging (MRI) demonstrated the tumor. The tumor was totally removed and the patient was discharged free of symptoms.

A review of trophoblastic diseases at the medical school of Dicle University.

Gestational trophoblastic disease cases encountered in 88 pregnant women during a period between January 1985 and June 1992 were retrospectively studied. During the same period we had 6800 deliveries. The incidence of gestational trophoblastic diseases was 12.9 per 1000 deliveries. Of these cases 72 (81.8%) were diagnosed as hydatidiform mole and 16 (18.2%) were diagnosed as choriocarcinoma in histopathological investigations. The preferred method of treatment for cases of hydatidiform mole was termination with suction curettage and oxytocin perfusion. Trophoblastic diseases were common in women with five or more pregnancies from rural areas and our incidence was higher when compared with similar studies. Moreover, our patients had low socio-economic and poor educational status. All these factors seem to be etiologic reasons, besides multiparity.

The blood supply of the hypoglossal nerve: the microsurgical anatomy of its cisternal segment.

BACKGROUND: While the characteristics of the vasculature of the second (intracanalicular) segment of the hypoglossal nerve are well known, the vascularization of the first (cisternal) segment of this nerve has not been examined so far. Many pathologic processes and malformations can be located in the premedullary cistern, which may affect the vasculature of the cisternal segment. Consequently, we decided to examine the blood supply of the cisternal segment. METHODS: The anatomic features of the cisternal segment and its vasculature were examined in 15 hypoglossal nerves after injection of india ink and gelatin into the vertebrobasilar arterial system. RESULTS: The cisternal segment was noted to consist of 3-15 long roots, which usually formed two trunks of the hypoglossal nerve. The roots of each nerve received blood from the anterolateral and the lateral medullary arteries, which ranged from 3 to 5 in number and between 100 microns and 500 microns in caliber. These arteries may arise from the perforating branches or the pontomedullary branch of the basilar artery; the vertebral artery or its perforators; the anterior spinal artery or its vascular roots; the posterior spinal artery; and the posterior inferior cerebellar artery. The main hypoglossal arteries, which ranged in diameter from 20 microns to 80 microns, always coursed along the dorsal surface of the roots of the hypoglossal nerve. CONCLUSIONS: The cisternal segment of the hypoglossal nerve was always vascularized by several vessels, which mainly originated from the vertebral artery and its branches. This observation was discussed from the neurosurgical point of view.

Prevalence, management and outcome in eclampsia.

OBJECTIVE: To review the management of eclampsia in our institution. METHOD: The prevalence, management and outcome of women with eclampsia over a period of 8 years were reviewed at our referral medical center. There were 444 patients with eclampsia among 5757 deliveries (1 in 12.96 deliveries or 7.71% of deliveries). Most of the cases were uneducated and had received no antenatal care. One hundred eighty-one cases were nulliparous (40.77%). High parities of more than five were observed in 27.93% of cases. A standard magnesium sulfate regimen, similar to Prichard's intramuscular regimen, was used. RESULTS: Magnesium sulfate effectively controlled the convulsions. The incidence of abdominal delivery among 397 cases with ante- and intrapartum eclampsia was 50.12%. Perinatal mortality was very high (591.47% 0) for all cases. Maternal complications were serious and led to maternal death in 42 women (9.46%). CONCLUSION: Eclampsia is still a serious obstetric complication particularly in uneducated women who do not receive antenatal care.

Budd-Chiari syndrome in a child secondary to membranous obstruction of the hepatic vein treated by percutaneous transluminal angioplasty. Report of a case.

Budd-Chiari syndrome (BCS) due to membranous obstruction of the hepatic vein and the inferior vena cava is rare in children. We report a child with BCS that had a membranous obstruction at the level of the hepatic veins. The web was successfully dilated percutaneously by balloon catheters. Symptoms and signs of obstruction improved without any complication. As percutaneous catheterization is an effective, safe and repatable procedure, we recommend this technique for treatment of children and adults with BCS due to membranous obstruction of the hepatic veins.

A comparative study of a gonadotropin-releasing hormone agonist and finasteride on idiopathic hirsutism.

OBJECTIVE: To compare the efficacy of finasteride and GnRH agonist in the treatment of idiopathic hirsutism. METHODS: Sixty women with hirsutism were randomly assigned to receive either 5 mg of finasteride or long-acting GnRH agonist (depot leuprolide 3.75 mg) intramuscularly monthly for six months. MAIN OUTCOME MEASURES: Hirsutism scores were measured according to the Ferriman-Gallway scoring system, and side-effects were monitored for six months of treatment. Blood samples were taken at each visit for assessment of endocrine (FSH, LH, estradiol, progesterone, total and free testosterone, androstenedione, DHEAS-S, 17-OH-P. SHBG), biochemical, and hematologic para- meters. RESULTS: All of the patients treated with finasteride or GnRH agonist showed neither menstrual abnormalities nor side-effects. The mean percent change (+/- SD) in hirsutism scores in the GnRH and finasteride groups was 36% +/- 14% and 14% +/- 11% at six months, respectively. Serum total testosterone, free testosterone, androstenedion and DHEA-S showed a meaningful decrease in patients treated with GnRH agonist. On the other hand, only serum total testosterone and free testosterone levels decreased with finasteride treatment (p < 0.05 and p < 0.0001, respectively).

Impact of perioperative lidocaine infusion and bis monitorization on remifentanil dosage in hypotensive anesthesia.

BACKGROUND: Combination of local and regional anesthetic agents are widely used in emergency and surgical setting and the interaction between the medications used in general anesthesia and these local and/or regional anesthetic becomes a growing concern in current patient management system. The interaction between general anesthetic agents and the local anesthetic agents given epidurally, spinally, intravenously or intramuscularly and the effects of BIS monitorisation on combined propofol-remifentanil anesthesia are examined in several studies. In literature, there is no research investigating the effect of lidocaine infusion on remifentanil and anesthetic dosage used in hypotensive anesthesia. The aim of this study is to examine this effect. PATIENTS AND METHODS: We studied 39, ASA I-II patients undergoing elective transsphenoidal endoscopic hypophyseal adenoma excision procedure. After preoperative examination and informed consent of the patient, monitorisation with non invasive blood pressure measurement, electrocardiography, pulse oxymeter and Bispectral Index (BIS) was performed. 0.9% NaCl infusion was started via a 20 G route. Lidocaine (1%) was given as 1.5 mg.kg(-1) hour-1 infusion after 1.5 mg.kg(-1) bolus dosage given in 10 minutes. Lidocaine infusion was started at the same time with anesthesia induction and was stopped after surgery. 0.9% NaCl was given as bolus dosage and as infusion in control group. Induction was maintained via propofol (1%) with 10 mg (1 ml) doses given in 5 seconds and it was applied in every 15 seconds until BIS < 45'. During maintenance of anesthesia desflurane-remifentanil-oxygen (50%)-air (50%) mixture was used. Desflurane was titrated by BIS measurement between 40 and 5012. Remifentanil infusion was started after propofol induction with 0.1 µg.kg(-1).min(-1) dosage and it was titrated between 0.1-0.5 µg.kg(-1).min(-1) levels. For intubation, rocuronium with 0.8 mg kg(-1) dosage was given during induction. After the surgical procedure, it was antagonised with neostigmine and atropine. For postoperative analgesia 1 g paracetamole was given IV after the surgery within 15 minutes and it was reapplied with 1 gr doses in every 6 hours. After extubation, the pain of the patients was examined at 15. minute at the recovery room with VRS (VRS; 0-no pain, 1-slight pain, 2-moderate pain, 3-severe pain). If VRS was greater than 2, 50 mg dolantine was given IM. For prevention of nausea and vomitting, 8 mg ondansetron was given IV. Perioperative total doses of remifentanil, desflurane (ml) (anesthesia machine records) and lidocaine (mg) were recorded after the surgery. Perioperative hemodynamic parameters (systolic, diastolic, mean blood pressures, heart rates) were recorded after monitorisation (basal), after intubation, after the start of the surgery and after extubation. RESULTS: There were no statistically significant difference between two groups with respect to patient characteristics (age, gender, weight, length, Basal Mass Index = BMI) (p > 0.05). The duration of anesthesia and surgery were also not different statistically (p > 0.05). There were no statistically significant difference between two groups with respect to remifentanil dose (p > 0.05). There were no statistically significant difference between two groups with respect to eye opening and extubation times (p > 0.05). When usage rates and amounts of dolantine, paracetamole and novalgine were compared, we found no statistically significant difference between two groups (p > 0.05). Basal mean arterial blood pressure measurements of the patients and mean arterial blood pressure measurements of the patients after induction, after intubation, 1 minute, 5 minutes, 10 minutes, 15 minutes after discharge of surgery and after extubation showed no statistically significant difference (p > 0.05). Basal heart rate measurements and the heart rates after induction, after intubation, 1 minute, 5 minutes, 10 minutes, 15 minutes after discharge of surgery and after extubation showed no statistically significant difference (p > 0.05). Basal BIS measurements and BIS measurements after induction, after intubation, 1 minute, 5 minutes, 10 minutes, 15 minutes after discharge of surgery and after extubation showed no statistically significant difference (p > 0.05). CONCLUSIONS: We found no statistically significant difference between two groups about different parameters. But new investigations with different local anesthetic agents may show sigificant difference and usage of these local anesthetic agents may be advised.

Rhino-orbito-cerebral mucormycosis: report of two cases and review of the literature.

Rhino-orbito-cerebral mucormycosis (ROCM) is a rare, fulminant opportunistic fungal infection that is mostly seen in immunocompromised or diabetic patients. The disease should be recognised and treated immediately. We present here MR imaging findings of two patients with histopathologically proven ROCM. One of the cases had a history of corticosteroid treatment and iatrogenic diabetes mellitus and although amphotericin B was started immediately, the disease progressed and surgical debridement was necessary. The second case was a patient with diabetes mellitus type 1 in whom ROCM had occurred following an abdominal surgery; amphotericin B treatment alone was adequate in this patient.
