Radiotherapy for stage I and II testicular seminomas: Secondary malignancies and survival

Introduction

Testicular seminoma affects relatively young men with excellent survival outcomes. There has been increasing concern that radiotherapy (RT) leads to secondary malignant neoplasms (SMNs) and subsequent mortality. We evaluated the effect of RT on incidence of SMNs and quantified cancer-related mortality and other causes of death for patients with stage I and II testicular seminoma.

Congenital spinal tuberculosis associated with asymptomatic endometrial tuberculosis: A rare case report

Spinal tuberculosis constitutes 50% of all musculoskeletal tuberculosis. However, literature regarding congenital spinal tuberculosis is very scanty. Congenital spinal tuberculosis was diagnosed in a two-month-old child on the basis of age at presentation (gibbus since three weeks of age), hepatomegaly, raised ESR, radiological destruction of D10-D11 vertebrae, asymptomatic maternal endometrial tuberculosis and tuberculous histopathology from CT guided biopsy specimen from D10 vertebra. Both child and mother were treated by antitubercular treatment. Child improved symptomatically, gibbus became less prominent and ESR became normal at the end of one year of treatment. Patient had no recurrence during last two years of follow-up. This is the first case of congenital tuberculosis of spine with a documented source of infection from asymptomatic maternal endometrial tuberculosis. CT guided core biopsy from vertebra/aspiration from the paravertebral abscess help in early diagnosis and treatment to reduce neurological morbidity and mortality. Endometrial biopsy help in establishing the diagnosis of congenital tuberculosis and adequate antitubercular treatment in such cases may provide protection to fetus in subsequent pregnancy.     

Histopathological analysis of hysterectomy specimens

The objective of this study was to explore the histopathological findings and the rate of removal of ovaries in hysterectomy specimens. This study took into account 328 hysterectomy specimens examined in the Department of Pathology, Mymensingh Medical College and in one private Pathology Laboratory in Mymensingh town from March to August, 2005. Formalin fixed paraffin embedded tissue sections stained with haematoxylin and eosin were examined under light microscope. Patients' age, parts of uterus examined and their histopathological findings were retrieved from laboratory records. The common histopathological findings were: chronic cervicitis (87.80%), leiomyoma (17.07%), uterine prolapse (16.72%), adenomyosis (3.96), non-specific endometritis (3.35%), squamous cell carcinoma of cervix (2.44%), endometrial polyp (2.44%), serous cystadenoma of ovary (2.44%) and endometrial hyperplasia (1.83%). Some of the specimens show more than one lesions in the body of uterus, of which coexistence of adenomyosis and leiomyoma was the most common. Neoplastic lesions in cervix were 4.27%, in body 16.92% and in ovaries 5.06%. Malignant neoplasms were found in cervix 71.43%, in uterine corpus 3.03% and in ovaries 25%. Ovaries of both sides were removed in 48.17% of total cases. Their median age was 45 years, lowest age 23 years and maximum age was 82. The rate of removal of both ovaries was found to be increasing with the increase of age. Only one case was found to be subtotal hysterectomy and others were total hysterectomy. The present study revealed that the most common histopathological cause of hysterectomy is chronic cervicitis. Most common neoplastic cause of hysterectomy is leiomyoma. The rationalities and the possible after effect of hysterectomy in sexual functions and other physiological impairment should be followed up.     

Salbutamol in acute organophosphorus insecticide poisoning – a pilotdose-response phase II study

Background: Treatment of acute organophosphorus (OP) insecticide poisoning is difficult, with many patients dying despite best care. Pre-clinical studies have shown benefit from salbutamol, possibly due speeding alveolar fluid clearance or reducing bronchoconstriction. In this small pilot dose-response study, we aimed to explore whether addition of nebulized salbutamol to standard care might improve resuscitation.

Methods: We performed a single-blind phase II study comparing the effect of two different doses of nebulized salbutamol versus saline placebo, in addition to standard treatment. Primary outcome was oxygen saturations over the first 60?min of resuscitation; secondary outcomes included heart rate, incidence of dysrhythmias, time to ‘atropinization’, atropine dose required, and mortality.

Result: Seventy-five patients were randomized to receive 5?mg (Salb5, n?=?25) or 2.5mg (Salb2.5, n?=?25) of salbutamol, or saline placebo (NoSalb, n?=?25), by nebulizer. Oxygen saturations did not differ between groups over the first 60?min of resuscitation (median AUC NoSalb: 1376 [95% CI 1282 to 1470], Salb2.5: 1395 [1305 to 1486], Salb5: 1233 [1100 to 1367]; p?=?.9898). Heart rate was also similar across the three arms. Median time to full atropinization, and atropine dose required, were the same for all three arms (NoSalb 15.0 [10–16] min and 12.6 [8.0–13.4] mg, Salb2.5 15.0 [10–16] min and 12.6 [9.3–16.8] mg, and Salb5 15.0 [10–20] min and 12.6 [10.7–20.6] mg; p?=?.4805 and p?=?.1871, respectively). Three (12%) patients died in the Salb2.5 and Salb5 groups and two (8%) in the NoSalb group.

Conclusion: This pilot study, within the limitations of its small size and variation between patients, found no apparent evidence that administration of nebulized salbutamol improved resuscitation of patients with acute OP insecticide self-poisoning. The data obtained provides a basis to design further studies to ultimately test the role of salbutamol in OP insecticide poisoning.     

Two dimensional echocardiographic demonstration of an unusual complication of aortic infective endocarditis

The two dimensional echocardiographic findings of aortic root abscess have been described. The echocardiographic findings in a patient with aortic valve endocarditis complicated by abscess formation, tear in the intima of the ascending aorta, and rupture of abscess cavity into the right ventricle are reported.
