Is the outcome of in-vitro fertilization and embryo transfer treatment improved by spontaneous or surgical drainage of a hydrosalpinx?

A pilot study was designed to examine whether the outcome of embryo transfer in women with a hydrosalpinx might be improved by surgical drainage of the hydrosalpinx at the time of oocyte collection for in- vitro fertilization treatment. A comparative, controlled but retrospective analysis of the results was performed of all women with infective tubal damage aged <40 years old, who had ovulatory cycles, a normal uterus and a partner with normal spermatozoa. A standardized treatment regimen was used. A maximum of three embryos were transferred. Hydrosalpinx was defined by prior hysterosalpingography and/or laparoscopy with transcervical dye injection. A total of 237 embryo transfer cycles in women with hydrosalpinges (tubal distension not visible in 151, visible but not drained in 30 and drained in 56) were compared with 705 embryo transfer cycles in women with tubal disease but no hydrosalpinx. Results were analysed in the first three cycles but also separately in the first cycle to check for bias. Success rates were higher in the first cycle, but did not significantly influence overall differences. Implantation rates were significantly reduced overall in the hydrosalpinx group (8.0 versus 13.2% for controls; P < 0.001), being 8.3% (P < 0.01) in the subgroup without evident tubal distension and 7.5% (not significant) in the drained hydrosalpinx group. This study shows that tubal damage with distal occlusion is associated with a marked reduction in embryo implantation, even in the absence of obvious fluid distension. Surgical drainage of distended hydrosalpinges appears to offer no benefit.      

Increased COVID-19 Lockdown Burden in Italian Adults with Gastrointestinal Diseases

Background: Coronavirus disease 2019 (COVID-19) causes not only severe illness but also detrimental effects associated with the lockdown measures. The present study aimed to evaluate reported lifestyle changes in a cohort of adults in Italy, including physical exercise, food choices, and psychological wellbeing, after two months of lockdown. Methods: A web survey on social media (Facebook and LinkedIn) of 32 multiple-choice questions aiming to evaluate the impact of the national COVID-19 lockdown in a sample of Italian adults. Results: We received 1378 complete responses (women 68.3%, mean age 39.5 ± 12.5 years). The percentage of participants reporting regular exercise decreased during lockdown (52 vs. 56.5%). The vast majority of people continued to consume the three traditional meals per day, but the consumption of meat, fish, and eggs significantly decreased. Women reported more frequent anxiety, sadness, fear, and feelings of insecurity than men. The factors predicting the worst outcome during the lockdown were being a woman, low education and income, gastrointestinal diseases. Conclusion: The lockdown has had a limited impact on food choices and physical exercise in Italian adults of our series, since most of them made an effort to improve their lifestyle. However, women with gastrointestinal diseases reported more frequent negative feelings and poor adaptation to the lockdown.     

Cavernous angioma of the cauda equina: Report of two cases and review of the literature

Two cases of intradural cavernous angioma of the cauda equina are reported, one of which presented with symptoms of subarachnoid hemorrhage. The clinical and therapeutic aspects of intradural angiomas, in particular those of the cauda equina, are discussed.     

Ilizarov external fixation in the treatment of comminuted leg fractures

Fifty consecutive comminuted leg fractures were treated by Ilizarov external fixation. Eleven were closed fractures, 37 were Grade II, and 2 were Grade III open fractures. Forty-five fractures healed within 6 months. In 5 fractures the Ilizarov device was removed and healing occurred by intramedullary nailing (2 cases) and decortication (3 cases). The causes of failure were: rapid peroneal union or bone fragment necrosis. Subjective tolerance and fracture stability are limited by septic loosening of the wires requiring frame removal after 6 to 8 months. Excellent results may be obtained (no leg length discrepancy, no angulation, no rotation, no joint stiffness), but the time required for union is long and additional surgery is required.     

The Epley maneuver for the treatment of benign paroxysmal positional vertigo

In recent years, different forms of physical therapy have been proposed for the treatment of benign paroxysmal positional vertigo (BPPV). These mainly consist of maneuvers aiming to reposition and disperse free-floating endolymph particles in the posterior semicircular canal. We report our experience with one of these procedures, the Epley maneuver (EM), in treating 30 cases of BPPV. Twenty-six patients (87%) were cured, while four (13%) did not respond to treatment. These results are similar to those reported in the literature for the EM and the Sémont maneuver.     

Myopathy and hypertrophic cardiomyopathy with selective lysis of thick filaments

We present a undescribed condition in a girl who died at 8 years of hypertrophic cardiomyopathy. Muscle and endomyocardial biopsies disclosed a selective loss of thick filaments ultrastructurally. In muscle biopsy histochemical abnormalities of myofibrillar AT-Pase were confined to type 1 fibres. Gel electrophoresis of muscle homogenate showed no qualitative abnormalities of slow and fast myosin heavy chains (MHC) and light chains, and the amount of the different myosin isozymes was in agreement with histochemical myofibrillar ATPase findings. The pathogenetic mechanisms have not been elucidated in this case but we suspect an abnormality of the-cardiac MHC gene, the only gene expressed in the heart and in type 1 skeletal muscle fibres.     

Circadian rhythm of glucose utilization in the pineal body of rats of different ages

Employing quantitative autoradiography, pineal body glucose utilization (GU) was measured in daytime or at night in prepubertal (aged 1 month), adult (aged 3 months), and mature (over 12 months old) rats. In prepubertal and adult rats, in daytime, GU values within the pineal tissue were homogeneously distributed around 65 mol glucose/100 g per min. In prepubertal animals no significant variations in GU were observed between daytime and nocturnal measurements. A circadian metabolic rhythmicity was evident in adult rats, with a GU peak measured at 2 a.m. In mature animals, GU also varied between day and night, with an increment in the relative difference between the two values. The present investigation is the first to demonstrate that circadian metabolic rhythmicity is absent before sexual maturation while it is enhanced in 12-month-old rats. These changes in pineal energy metabolism with advancing age are intriguing in view of the concept that the pineal gland may be involved in functional changes occurring during the process of aging.

Four cases of ependymoma of the filum terminale occurring in childhood are reported. The clinical, therapeutic and prognostic features seen at this age and in adults were compared.     

Dermoid and epidermoid cysts of the midline in the posterior cranial fossa

Clinical features and surgical outcome of 16 patients with dermoid or epidermoid cysts on the midline of the posterior cranial fossa are compared. Salient points in the comparison are the younger age, presence of associated malformations and better prognosis of dermoid cyst.
