Treating male infertility.

Most causes of male infertility are treatable, and the goal of many treatments is to restore the ability to conceive naturally. The process of spermatogenesis is essential for human reproduction. A simple sounding process is mediated by a variety of factors, including multiple hormonal influences.

Dental and health aspects in the co-occurrence of Treacher Collins and Down syndromes: Case report.

The goal of this case report is to identify the dental care of a patient who has co-occurrence of Treacher Collins and Down syndromes. It is the third case reported in the literature and the first relating dental treatment under general anesthesia and multidisciplinary importance. It was necessary the child's nutritional assessment in this case.

Alagille syndrome: Oral manifestations-A case report.

The Alagille syndrome (AGLS) is a rare condition, with few studies reported in the literature, especially in the field of dentistry. It consists of a disease involving many systemic problems and specific facial features. The liver and heart are the most intensely affected organs, and depending on the severity, it may be necessary to perform transplants.

SARS-COV-2 and Male Reproductive Health.

Critical challenges for the public and private health, research, and medical communities have been posed by the COVID-19 outbreak. Some of these challenges are related to the possible adverse effects of SARS-CoV-2 on male reproductive health, and whether other potential modes of transmission may occur, such as sexual transmission. Moreover, concerns have been raised in terms of whether the COVID-19 outbreak may have an impact on fertility worldwide.

Testicular sperm extraction in men with sertoli cell-only testicular histology - 1680 cases.

Objective: To study the outcomes of testicular sperm extraction (TESE) among men with pure Sertoli cell-only histology identified during diagnostic testicular biopsy.

Methods: This retrospective cohort study involved 1680 cases of patients with nonobstructive azoospermia (NOA) diagnosed with pure Sertoli cell-only histology who underwent testicular biopsy with TESE in a reference center in Brazil by a single surgeon. Sperm retrieval rates (SSR) were the main outcome measure.

Do you know this syndrome? Leopard syndrome.

Hypertrophic cardiomyopathy is known as Leopard syndrome, which is a mnemonic rule for multiple lentigines (L), electrocardiographic conduction abnormalities (E), ocular hypertelorism (O), pulmonary stenosis (P), abnormalities of genitalia (A), retardation of growth (R), and deafness (D). We report the case of a 12-year-old patient with some of the abovementioned characteristics: hypertelorism, macroglossia, lentigines, hypospadias, cryptorchidism, subaortic stenosis, growth retardation, and hearing impairment. Due to this set of symptoms, we diagnosed Leopard syndrome.

Reproductive planning in times of Zika: getting pregnant or delaying plans? The opinion of the Brazilian Society of Assisted Reproduction Committee - a basis for a bioethical discussion.

Although the causality between Zika virus, microcephaly, and other central nervous system disorders has been taken for granted by the scientific community, many uncertainties remain. The gap of knowledge at the moment is large enough to remove part of the confidence physicians have on the advice given to patients - and infertile women in particular - on their reproductive plans. Pretreatment serologic screening is a possible strategy to offer more confidence for individuals choosing to bear children regardless of the Zika virus, but the tests currently available do not seem to be sufficiently adequate.

Primary Occipital Encephalocele in an Elderly Patient.

The encephalocele is a condition characterized by the protrusion of the intracranial contents through a bone defect of the skull. The authors report a clinical case of an 80-year-old woman with primary occipital encephalocele on the right side and that was affected by trauma and presented liquor fistula and infection. Tomographic sections were obtained by injection intravenous of contrast.

Racial and ethnic differences in assisted reproduction treatment outcomes: the benefit of racial admixture.

The goal of the present study was to determine whether racial and ethnic differences affect the outcomes of assisted reproductive technology in the Brazilian population. 1497 patients undergoing intracytoplasmic sperm injection (ICSI) cycles were split into groups according to the patient's ethnicity: Caucasian (n = 2131), Mestizo (n = 358), Asian (n = 174), Black (n = 115) and Indian (n = 260). ICSI outcomes were compared among the groups.

Incidence and anatomy of cardiac malformations in children conceived by assisted reproduction techniques - A review.

The aim of this study is to identify the occurrence of cardiac malformations occurred in children conceived by assisted reproduction techniques (ART) in the international literature in Medline database from 1999 to 2012. The search returned data on 32,000 births, whose 21,000 were conceived naturally and 11,000 were conceived by ICSI and/or IVF. The incidence of cardiac malformations in general population situations was 0.

Stylohyoid syndrome: surgical approach.

The best-known cervicopharyngeal pain is Eagle syndrome, in which symptomatic elongation of the stylomandibular process occurs and may be accompanied by stylohyoid ligament calcification. Among the causes of elongation of the styloid process, the following may be mentioned: history of trauma, styloid ligament calcification, and formation of bony tissue in the insertion of the styloid ligament. When there is no history of trauma or surgery, it is called the stylohyoid syndrome.
