Portal vein thrombosis after laparoscopic splenectomy for systemic mastocytosis: a case report and review of the literature

INTRODUCTION: Laparoscopic splenectomy has become the surgical procedure of choice for various diseases of the spleen. Portal vein thrombosis (PVT) after splenectomy occurs in 0.5% to 22% of patients. Symptoms are nonspecific and include fever, abdominal pain, and epigastric distress. Risk factors for PVT after splenectomy include underlying hematologic disorders, massive splenectomy, and other hypercoagulable states. METHODS: We describe a case of PVT in a woman who underwent laparoscopic splenectomy for symptomatic splenomegaly secondary to systemic mastocytosis. The patient was discharged from the hospital without anticoagulation and experienced nonspecific symptoms beginning 10 days postoperatively. Diagnosis of PVT was made by contrast-enhanced abdominal computed tomography. The patient had no underlying risk factors. Anticoagulation treatment facilitated recanalization of the portal vein and this was verified by Doppler ultrasound at follow-up. CONCLUSIONS: PVT after laparoscopic splenectomy is not uncommon. Signs and symptoms are vague and require a high index of suspicion for timely diagnosis. Anticoagulation is the treatment of choice and allows recanalization of the portal system in the majority of cases.     

The natural history of a mistreated ipsilateral Galeazzi and Monteggia lesion: report of a case 39 years post-injury

Galeazzi injury combined with ipsilateral Monteggia lesion is extremely rare. A 45-year-old male patient with a mistreated Galeazzi lesion combined with an ipsilateral Monteggia fracture at the age of 6 is presented. Thirty-nine years post-injury his elbow was asymptomatic and stable and his distal radioulnar and radiocarpal joints were also asymptomatic. The strength of the limb was equal to the unaffected contralateral upper limb and he was able to work manually as a waiter for the last 20 years without any problem. The only obvious defect was a 30 degrees lack of elbow flexion and a 10 degrees lack of forearm pronation in comparison to the normal side.     

Cardiac arrest and cardiopulmonary resuscitation in “hostile” environments: Using automated compression devices to minimize the rescuers’ danger

Mechanical automated compression devices are being used in cardiopulmonary resuscitation instead of manual, “hands-on”, rescuer-delivered chest compressions. The -theoretical- advantages include high-quality non-stop compressions, thus freeing the rescuer performing the compressions and additionally the ability of the rescuer to stand reasonably away from a potentially “hazardous” victim, or from hazardous and/or difficult resuscitation conditions. Such circumstances involve cardiopulmonary resuscitation (CPR) in the Cardiac Catheterization Laboratory, especially directly under the fluoroscopy panel, where radiation is well known to cause detrimental effects to the rescuer, and CPR during/after land or air transportation of cardiac arrest victims. Lastly, CPR in a coronavirus disease 2019 patient/ward, where the danger of contamination and further serious illness of the health provider is very existent. The scope of this review is to review and present literature and current guidelines regarding the use of mechanical compressions in these “hostile” and dangerous settings, while comparing them to manual compressions.

Evaluation of sexual function in hypertensive men receiving treatment: a review of current guidelines recommendation

IntroductionIt has been suggested that some classes of antihypertensive drugs may induce or exacerbate sexual and/or erectile dysfunction (ED) more than others. Sexually related side effects of antihypertensive treatment may compromise patient's and partner's quality of life. Often, these side effects can lead to withdrawal or poor compliance with therapy resulting in abnormal blood pressure and associated morbidity.AimThe aim of this study was to evaluate whether hypertension clinical practice guidelines (CPGs) address ED and/or other sexual issues as either an adverse outcome of chosen therapy or as a factor to consider in treatment decision.MethodsHypertension CPGs were identified by searching PubMed (from 2000 to current), the World Wide Web, bibliographies of retrieved guidelines, and official home pages of major medical societies.Main Outcome MeasuresThe main outcome measures used for this study were guidelines assessment using a set of author‐determined survey questions.ResultsTwelve CPGs were identified and analyzed. From these 12, only three emphasized the importance of assessing sexual function prior to initiation and/or follow‐up of antihypertensive therapy; only five described potential sexual side effects associated with some drugs; only two provided specific management recommendations on commencing antihypertensive therapy in sexually active men or those with preexisting ED and address the timeline of the potential drug‐induced impairment of sexual function.ConclusionsOnly a minority of CPGs for the treatment of hypertension consider ED or other sexual issues as either an adverse outcome or as a factor to consider in treatment. Sexual function is an important aspect of quality of life for both the individual and his partner. It is therefore imperative to select therapy with the least possible potential for causing sexual sequelae and enable the best achievable balance between therapeutic efficacy, quality of life, and therapeutic compliance. Based on these results, our proposed algorithm attempts to effectively apply available evidence to clinical practice.

Depressive symptomatology and the prevalence of cardiovascular risk factors among older men and women from Cyprus; the MEDIS (Mediterranean Islands Elderly) epidemiological study

Aims. The purpose of this paper is to explore the link between symptoms of depression and the prevalence of cardiovascular risk factors in older adults. Methods. During 2005, 136 older men and 164 women from various parts of Cyprus agreed to participate in the study. The sampling was random and multistage (according to age–sex distribution of the referent population). All participants were living in the community and not in institutions. Among several socio‐demographic, bioclinical, lifestyle and dietary characteristics, depressive symptoms were assessed using the short version of the Geriatric Depression Scale (GDS). Results. Participants without signs of depression, typically, have fewer cardiovascular risk factors (i.e. hypertension, hypercholesterolemia, diabetes and obesity) than those with moderate or severe symptoms. Even when behavioural variables (e.g. diet, smoking, exercise) are statistically controlled, participants that are higher than others on depression are more likely to have hypertension and/or hypercholesterolemia than those with lower scores. Every one‐unit increase in GDS score (range 0–15) is associated with a 12% higher likelihood of having an additional cardiovascular disease risk factor. Conclusions. Symptoms of depression are positively associated with the number of cardiovascular risk factors in ‘healthy’ older adults, irrespective of lifestyle behaviours (e.g. smoking, dietary intake and physical activity). Relevance to clinical practice. Healthcare providers should consider the implications of both the presence and nature of this relationship in their continuing care of older adults.     

Balloon kyphoplasty for the treatment of pathological vertebral compressive fractures

Background Previous clinical studies have shown the safety and effectiveness of balloon kyphoplasty in the treatment of pathological vertebral compression fractures (VCFs). However, they have not dealt with the impact of relatively common comorbid conditions in this age group, such as spinal stenosis, and they have not explicitly addressed the use of imaging as a prognostic indicator for the restoration of vertebral body height. Neither have these studies dealt with management and technical problems related to surgery, nor the effectiveness of bone biopsy during the same surgical procedure. This is a prospective study comparing preoperative and postoperative vertebral body heights, kyphotic deformities, pain intensity (using visual analogue scale) and quality of life (Oswestry disability questionnaire) in patients with osteoporotic vertebral compression fractures (OVCFs) and osteolytic vertebral tumors treated with balloon kyphoplasty.Methods Thirty-two consecutive patients, 27 OVCFs (49 vertebral bodies [VBs]) and 5 patients suffering from VB tumor (12 VBs) were treated by balloon kyphoplasty. The mean age was 68.2 years. All patients were assessed within the first week of surgery, and then followed up after one, three and six months; all patients (27 OVCFs and 5 tumor patients) were followed up for 12 months, 17 patients (14 OVCFs and 3 tumors) were followed up for 18 months and 9 patients (8 OVCFs and 1 tumor) were followed up for 24 months (mean follow up 18 months). The correction of kyphosis and vertebral heights were measured by comparing preoperative and postoperative radiographic measurements.Results Thirty-one patients (96.9%) exhibited significant and immediate pain improvement: 90% responded within 24 h and 6.3% responded within 5 days. Daily activities improved by 53% on the Oswestry scale. In the OVCF group, kyphosis correction was achieved in 24/27 patients (89.6%) with a mean correction of 7.6°. Anterior wall height was restored in 43/49 VBs (88%) (mean increment of 4.3 mm), and mid vertebral body height was restored in 45/49 VBs (92%) (mean increment of 4.8 mm). Edema (high intensity signal) on short tau inversion recovery (STIR) was evidenced in all OVCF patients who experienced symptoms for less than nine months and was associated with correction of deformity. Cement leakage was the only technical problem encountered; it occurred in 5/49 VBs (10.2%) of the osteoporotic group and 1/12 VBs (8.3%) of the tumor group but had no clinical consequences. The incidence of leakage to the anterior epidural space was 2%. Spinal stenosis was present in three patients (11.1%) who responded successfully to subsequent laminectomy. Retrieval of tissue samples for biopsy was successful in 10/15 cases (67%). New fractures occurred in the adjacent level in 2/27 OVCF patients (7.4%).Conclusions Associated spinal stenosis with OVCF should not be overlooked; STIR MRI is a good predictor of deformity correction with balloon kyphoplasty. The prevalence of a new OVCF in the adjacent level is low.     

Temperature differences are associated with malignancy on lung lesions: a clinical study

Background  

Although new endoscopic techniques can enhance the ability to detect a suspicious lung lesion, the primary diagnosis still depends on subjective visual assessment. We evaluated whether thermal heterogeneity of solid tumors, in bronchial epithelium, constitutes an additional marker for the diagnosis of benign and malignant lesions.     

No difference in clinical outcome after posterolateral lumbar fusion between patients with isthmic spondylolisthesis and those with degenerative disc disease using pedicle screw instrumentation: a comparative study of 112 patients with 4 years of follow-up

We compared the clinical outcome after spinal fusion between patients with isthmic spondylolisthesis and those with degenerative disc disease of the lumbar spine, using multiple logistic regression analysis. A questionnaire describing medication, pain, vocational status and patient satisfaction was mailed to all the patients at a median interval of 4 years after their operation. Fusion was evaluated on plain radiographs at a minimum of 12 months after surgery, and patients were classified as fused or not fused. The overall satisfaction rate was 70%. The results of the present study showed no difference in the outcome after spinal fusion between the two groups of patients. The factors that significantly increased the likelihood of an optimal result - defined as patient satisfaction, return to work, and reduced medication - were male gender, being in work prior to surgery, and being a non-smoker. Since spinal fusion is an expensive treatment with potentially serious risks, and leaves one-third of the patients with an unsatisfactory result, we believe that more studies focusing on the indications for surgery should be performed.
