The morphology of human ejaculatory ducts has not been well established. The objective of this study was to describe macroscopic and microscopic anatomy of ejaculatory ducts. We conducted a systematic review using MEDLINE, Scopus, PubMed, and Cochrane databases. Search terms were: "ejaculatory ducts," "seminal colliculus," "prostatic utricle," "anatomy," "histology," "radiology," and "embryology." We only included studies assessing adult (>18 years) humans published before November 1, 2019. We excluded studies describing pathological ducts and case reports. Independent authors extracted data using predefined criteria. Fourteen studies were included in the qualitative synthesis. Usually, the ejaculatory ducts entered the prostate by piercing the central part of its base. Most studies identified an anteromedial curve of the ducts at the outset within the prostate, their subsequent course being a straight path towards the seminal colliculus, their terminal parts diverging immediately before joining the prostatic urethra. However, the morphology of the terminal part of the ducts was inconsistent. The mean length of the ducts ranged from 1.4 to 2.2 cm. In conclusion, the luminal diameter gradually decreased as the ducts traveled towards the seminal colliculus. Ejaculatory ducts angulate anteromedially at their onset within the prostate and travel straight towards the seminal colliculus. Their terminal parts diverge immediately before joining the prostatic urethra. However, the reported dimensions of the ducts differ among studies.

Morgellons disease (MD) is a multi-system disorder characterized by multicolor filaments extruding out of the skin along with an array of dermatologic and neuropsychiatric symptoms. It was previously termed Delusional parasitosis. However, published scientific data found the association of MD symptoms with the systemic manifestations of Lyme disease, caused by Borrelia spirochete. In a retrospective study of 122 MD patients, skin specimens were examined and 96% of them showed Borrelia spirochete in their histology sample. Hence, this association suggests that spirochete infection could be a possible cause of chronic illness in MD patients, and this rejected the physician's perception that MD lesions might be self-inflicted. A cohort study reported tick-borne co-infections among MD patients, which could also be an etiological factor for dermopathy in MD patients. Some literature also discussed neuropsychiatric manifestations like cognitive impairment, dementia anxiety, depression, paranoia, and sensory hallucinations in Lyme disease and associated tick-borne infection. The objectives of this review are to identify the differences in the past and current perception regarding the pathogenesis of MD and determine the associations of spirochetal and tick-borne diseases with MD and psychiatric illnesses. More than 50 new research articles and case reports were reviewed and only 31 articles were shortlisted and used as references. This review has a detailed discussion on Morgellons disease and its association with Spirochete infection.

Piscine mycobacteriosis is a fatal fish illness that affects a variety of species globally. It affects over 200 species of freshwater and marine fish. Several species of Mycobacterium are responsible among them Mycobacterium marinum is the comment. It also affects humans when exposed to contaminated water. In fishes, the symptoms include eroded fins, body surface coated with heavy mucus, changing pigmentation, swelling of abdomen, ulcerative dermal necrosis, and scale loss. In humans, the infection is classified into three clinical groups. Type I is a self-limiting, verruca lesion. Type II is single or numerous subcutaneous granulomas in the presence or absence of ulceration. Type III is deep infections of the tenosynovium, bones, bursa, or joints, resulting in tenosynovitis, osteomyelitis, and septic arthritis. The diagnosis is made by Ziehl-Neelsen acid-fast staining, culture, biochemical reaction, and PCR being the most reliable approach. Piscine mycobacteriosis is treated by antibiotics and vaccination has been considered for its long-term prevention in order to reduce morbidity and mortality. Morgellons disease (MD) is a filamentous dermopathy in which lesions with strange filamentous inclusions appear out of nowhere. Furthermore, formication may accompany dermopathy. The identification of Borrelia spirochetes directly in Morgellons disease patient specimen is constant and repeatable when sensitive and precise detection techniques are utilized. It has been diagnosed by microscopy, histology and molecular diagnostic techniques which are highly sensitive and specific. Morgellons disease is still a myth therefore its treatment is evolving, up to date it has been treated symptomatically.

Morgellons Disease (MD) is a multisystem disorder with a primary symptom characterized by emerging of small fibres from the skin. For years, many doctors thought MD is a psychiatric disorder and treated the patients with antipsychotic drugs, behavioural therapy and counselling. However, recent studies suggest that MD is a completely different entity from psychiatric disorders. Morgellons pathophysiology remains a mystery even now. It was previously considered to be a delusional disorder due to its similarity to delusions of parasitosis or delusional infestation described many years ago. This constellation of symptoms has not been well studied in different populations, however, a study in North California found a prevalence of 3.65 per 100,000 for MD, with Caucasian and female predominance.

Although there is no scientifically reported evidence of a link between Morgellons Disease (MD) and electromagnetism, this article investigates the possible causes if different bacterial organisms to be implicated in the etiology of MD. Spirochetes, for example, the suggested main pathogen linked to MD, are electroactive and, if indeed are the underlying pathology, could cause chemical precipitation of calcium carbonate crystals, resulting in increased electrical conductivity. Microbiotas such as E.coli, Shewanella, and Listeria have previously been related to electroactive characteristics. Furthermore, the bacteria-induced deposition of pyrite, calcium carbonate, calcium alginate, and magnetite in the epidermis could explain some MD patients' inexplicable symptoms. While only some of these microorganisms are proven in MD patients, the exact etiology of the disease is yet to be determined. It's possible that we'll never find a link at all, but that doesn't rule out the possibility that one exists in the first place. In this review, we attempt to suspend disbelief that MD patients could exhibit such symptoms, and instead investigate how researchers could support their claims with science and compassion, instead of repudiating them.
