A strong reconstruction option for tissue loss on hand and wrist due to firearm injury in the Syrian war: Reverse posterior interosseous flap

All of the injuries were the open injuries with bone or tendon structures in the hand and wrist region as a result of the firearm injury (FI) in the Syria. In the study, we assessed the outcomes of the posterior interosseous flap (PIF) on hand and wrist that we used for the Syrian injured people including civilians and soldiers in this War. PIF was applied to 77 patients who composed of 43 female and 34 male that all patients were evaluated for tissue loss resulting from gunshot wounds and injured in the War between 2014 and 2020 years with tissue loss in hand and wrist as a result of FI. The flap survival rate was 100% for all the patients. The dimensions of flaps ranged from 4.1 cm × 2.2 cm to 9cm × 5.4 cm with 0.51 ± 0.12 cm thickness. The mean pedicle length was 6.33 ± 1.08 cm. The surgery for PIF took 68.8 ± 22.1 minutes, while blood loss was 60 ± 24 mL. We observed no palsy conditions including the posterior interosseous nerve. The donor sites were treated by primary intention in the patients. We found the superiority of PIF with the postoperative follow-up comfort, ease of fracture healing, easy and fast, easy-to-apply method and no second additional session requirement in FI patients. We did not detect flap necrosis in any patient or observe a flap-related complication. As a result of the present study, it strongly supports the thesis that PIF is the best option in these cases.     

A Mysterious Crescent in the Heart: Ruptured Sinus of Valsalva Dissecting Interatrial Septum,Multimodality Imaging,and Full Recovery

A 59‐year‐old man who was admitted to the emergency department with new and spontaneous onset of fatigue, dyspnea, and palpitations. There was neither a history of trauma, chest pain, nor infection. Transthoracic two‐ and three‐dimensional echocardiography and computer tomography demonstrated sinus of Valsalva aneurysm rupture dissecting interatrial septum and leading to a huge thrombus formation in it. The diagnosis with multimodality imaging performed within hours, and urgent surgery saved the patient's life.     

Will a second biopsy sample affect treatment decisions in patients with chronic hepatitis B?

Background and aim

Liver biopsy is the gold standard for assessment of fibrosis in patients with hepatitis B. However, it has some disadvantages, including inter-observer and intra-observer variability in biopsy interpretation and specimen variation. A standard biopsy specimen represents only about 0.0002 % of the whole liver. It has been shown that two biopsy samples collected during a procedure have significant influence on the diagnostic performance of interpretation in patients with hepatitis C or non-alcoholic steatohepatitis. Therefore, we aimed to assess the influence of collecting two liver biopsy samples during a single procedure for staging and grading chronic hepatitis B.

Patients and methods

27 patients were included in the study. The median age of the patients was 43.51 ± 11.69. Fifteen patients were female, 12 patients were male. In the biopsy procedure, two samples of liver lobes were obtained. Grade and stage scores were compared between the two samples. Fibrosis staging and grading were assessed according to the Ishak scoring system.

Results

Numbers of portal tract and biopsy size were equal in the two samples. There was a significant difference between the samples in terms of histological activity index (p value = 0.04). However, the difference was not enough to distinguish the mild and moderate stages. On the other hand, no significant difference in fibrosis staging between the two samples was found.

Conclusions

With this relatively small size of patients, in this study, we showed that a proper liver biopsy size is sufficient to predict treatment decisions in chronic hepatitis B patients. However, further studies are needed to show the association of sampling variability in patients with hepatitis B.

     

The effect of platelet-rich plasma on motility changes in experimental caustic esophageal burn

Background

Besides stricture formation, diminished esophageal motility after caustic esophageal burns also plays a role in the deterioration of the clinical course. In this study, we aimed to investigate the effect of caustic burn on the esophageal contractions and the effect of platelet-rich plasma (PRP) on these changes.

Methods

Twenty-one Wistar albino rats were divided into three groups [Sham operation (n?=?8), caustic esophageal burn with NaOH (n?=?6), PRP treatment after caustic burn (n?=?7)]. After 3 weeks, esophagectomy was performed and contractions and EFS responses were evaluated in the organ bath.

Results

KCl- and acetylcholine-induced responses were reduced in the Burn group, but increased in Sham and PRP groups (p?<?0.05). EFS responses were higher in Burn group compared to the other groups. Response with l-arginine was increased in Burn group, but decreased in PRP group. There was more decrease in the contraction in Sham and PRP groups compared to the Burn group after SNP (sodium nitroprusside) incubation (p?<?0.05). L-NAME (Nω-Nitro-l-arginine methyl ester) did not change the EFS responses in the Burn group, but EFS responses were decreased significantly in Sham and PRP groups (p?<?0.05). EFS responses were decreased in all groups, but more in the Sham and PRP groups after Y-27632 (Rho-kinase inhibitor) incubation (p?<?0.05).

Conclusions

For the first time, we demonstrated that both cholinergic and non-adrenergic non-cholinergic mechanisms are responsible for the altered motility in corrosive esophageal injury. Our results suggest that PRP treatment may be helpful in regulating the esophageal motility and decreasing altered contractions in corrosive burns. This effect may also contribute to the reduction of stricture formation, especially by reducing inappropriate contractions of the esophageal wall during the post-burn healing phase.

     

Pulmonary Arterial Hemodynamic Assessment by a Novel Index in Systemic Sclerosis Patients: Pulmonary Pulse Transit Time

Objectives

Systemic sclerosis (SSc) is a chronic, inflammatory, and autoimmune connective tissue disease that is associated with vascular lesions, and fibrosis of the skin and visceral organs. Cardiac complications may occur as a secondary effect of SSc as a result of pulmonary arterial hypertension and interstitial lung disease. The objective of this study was to assess whether the pulmonary pulse transit time (pPTT) could serve as a diagnostic marker for pulmonary arterial alterations in patients with SSc, prior to development of pulmonary hypertension.

Methods

Twenty-five SSc patients as a study group and 25 age- and sex-matched healthy volunteers for the control group were recruited to the study. Right ventricle function parameters, such as tricuspid annular plane systolic excursion (TAPSE), estimated pulmonary artery systolic pressure (ePASP), right ventricular dimensions, right ventricle fractional area changes, and myocardial perfusion index (MPI) were measured and calculated. Pulmonary pulse transit time was defined as the time interval between the R-wave peak in the ECG and the corresponding peak late systolic pulmonary vein flow velocity.

Results

Right ventricle myocardial performance index (RVMPI) and eSPAP were significantly higher in the SSc group than the controls (p?=?0.032, p?=?0.012, respectively). Pulmonary pulse transit time and TAPSE was shorter in the patients with SSc (p?=?0.006, p?=?0.015, respectively). In correlation analysis, pPTT was inversely correlated with RVMPI (r?=???0.435, p?=?0.003), eSPAP (r?=???0.434, p?=?0.003), and disease duration (r?=???0.595, p?=?0.003). Conversely, it positively correlated with TAPSE (r?=?0.345, p?=?0.022).

Conclusion

pPTT was found to be shorter in SSc patients. pPTT might serve as a surrogate marker of pulmonary hemodynamics in patients with SSc, even prior to the development of pulmonary hypertension.

     

The relationship between T-wave polarity and clinical as well as angiographic findings in the early stage of acute myocardial infarction

BACKGROUND: Restoration of a positive T-wave in the chronic stage of myocardial infarction (MI) is usually seen in patients with a non-Q-wave (non-transmural) MI, where a viable tissue is present. The causes and significance of a positive T-wave in the early phase of acute MI are not clear. AIM: To investigate angiographic and clinical characteristics of patients with a positive T-wave in the early stage of acute MI. METHODS: We evaluated the clinical and angiographic data in relation to T-wave polarity in 188 patients with acute MI. Coronary risk factors, pre-infarction angina, CK-MB level, left ventricular ejection fraction and angiographic findings were analysed. Death, cardiogenic shock, ventricular tachycardia/fibrillation and high-degree atrioventricular block were regarded as in-hospital complications. All electrocardiograms were divided into two groups, according to the shape of the T-wave, as exhibiting a positive T-wave or negative T-wave. RESULTS: A positive T-wave was present in 30 (15.9%) patients. None of the patients with a positive T-wave had three-vessel disease compared with 21.5% of patients with a negative T-wave (p <0.04). In-hospital complication rates were similar in both groups. CONCLUSIONS: Patients with a positive T-wave in the early phase of acute MI have significantly less frequently three-vessel disease than patients with a negative T-wave.     

Compensatory enlargement of human coronary arteries during progression of atherosclerosis is unrelated to atheroma burden: serial intravascular ultrasound observations from the REVERSAL trial.

AIMS: On the basis of the evidence from autopsy studies, it is accepted that compensatory enlargement (remodelling) of coronary arteries during progression of atherosclerosis diminishes once atheroma burden (cross-sectional area stenosis) reaches approximately 40%. Our aim was to evaluate whether atheroma burden is a limiting factor for coronary arterial remodelling using in vivo serial intravascular ultrasound (IVUS). METHODS AND RESULTS: From the cohort of the Reversal of Atherosclerosis with Aggressive Lipid Lowering (REVERSAL) trial, we identified 210 focal coronary lesions at baseline IVUS. Of these, 128 lesions that had an increase in atheroma area at the 18-month follow-up IVUS were included in the analysis. Lesions were matched at baseline and follow-up. The increase in external elastic membrane (EEM) area for each mm(2) increase in atheroma area was not significantly different in lesions with <40 and >or=40% atheroma burden at baseline (1.62 vs. 1.28 mm(2), P=0.30). There were no correlations between atheroma burden at baseline and change in EEM (r=0.02, P=0.86) or change in lumen (r=0.04, P=0.64) areas. CONCLUSION: Assessment of coronary arterial remodelling by serial IVUS revealed that compensatory remodelling is not limited by atheroma burden. Atheroma burden is not a determinant of arterial enlargement during the progression of atherosclerosis.     

Intracavitary left ventricular hydatid cysts ruptured during cardiopulmonary resuscitation in a patient with acute myocardial infarction

Cardiac hydatid cyst is a rare complication of parasitic infection caused by Echinococcus granulosus. Cardiac involvement occurs in only 0.2-2% of hydatidosis cases. Rupture of hydatid cysts into cardiac chambers is very rare. In this report, we present a case of intracavitary left ventricular hydatid cysts ruptured during cardiopulmonary resuscitation in a patient with acute myocardial infarction.     

Alexithymia and anger in patients with fibromyalgia

Our objective was to delineate the relevance of the personality construct alexithymia and anger-in in patients with fibromyalgia syndrome. Fifty subjects with fibromyalgia syndrome were compared to 20 subjects with rheumatoid arthritis and 42 healthy controls on the measures of anxiety, depression, anger, alexithymia, pain intensity and disability. There was a significant difference on the measures of anxiety and anger between FMS and RA groups, and also between FMS patients and healthy controls. There was a significant difference between FMS patients and healthy controls on the measures of depression, difficulty in identifying feelings subscale of TAS (TAS-dif), and total alexithymia scores. When the severity of pain was controlled for, there was a significant difference on the measures of anger and alexithymia between the FMS and the RA groups. Fibromyalgia patients were more alexithymic than rheumatoid arthritis patients even when the level of depression was controlled for. Anger towards oneself, which is anger-in, was higher in patients with fibromyalgia patients than in the rheumatoid arthritis sample. A stepwise regression model showed that the anger-out scores and the anxiety scores predicted the level of pain severity, and this explained 32% of the variance in the fibromyalgia syndrome group. Although anger-in is consistently higher in fibromyalgia patients, it is the behavioral expression of anger, together with anxiety, that predicts the severity of the pain. The difficulty of identifying feelings, rather than other dimensions of alexithymia, seems to be associated with fibromyalgia.Abbreviations CLBP Chronic low back pain - FMS Fibromyalgia syndrome - RA Rheumatoid arthritis - VAS Visual analog scale
