Chronic pelvic pain of "unknown origin" in the female.

The remit of this review is confined to the experimental scientific works and surgeries based on the Integral Theory Paradigm (ITP). Chronic pelvic pain (CPP) is a major societal problem which is said to occur in up to 20% of women. The pathogenesis of CPP of "unknown origin" is said to be unknown and CPP is said to be incurable. According to the ITP, however, CPP is said to be mainly caused by the inability of loose or weak uterosacral ligaments (USLs) to mechanically support visceral nerve plexuses (VPs), T11-L2 and S2-4. These fire off de novo impulses, interpreted by the cortex as pain coming from the end organs. CPP, when it occurs simultaneously in multiple pelvic sites, is associated with uterine/apical prolapse (often minimal) and bladder symptoms such as overactive bladder (OAB), nocturia, retention. This combination of symptoms was described in 1993 as the "posterior fornix syndrome" (PFS). As such, CPP when associated with the PFS, is potentially curable by surgical repair of USLs. However, patients with CPP generally complain only of one symptom, CPP. This is known as the "Pescatori iceberg" effect. Other PFS symptoms are "under the surface" and must be sought out by direct questioning. The diagnostic algorithm is helpful in locating other associated symptoms. Definitive diagnosis of CPP, caused by USL laxity, is immediate alleviation of pain by mechanical support of USLs by using the speculum test or by tampons in the posterior fornix. Treatment of CPP can be non-surgical, by strengthening USLs by squatting exercises, supporting USLs mechanically with tampons or USL surgery. Coexisting bladder symptoms are (variously) improved or cured. URL for CPP https://www.pelviperineology.org/volume/36/issue/3.

Interstitial cystitis/bladder pain syndrome: when part of the posterior fornix syndrome is potentially curable surgically.

Interstitial cystitis/bladder pain syndrome (IC/BPS) is defined as chronic pelvic pain plus a bladder symptom, usually urge. Evidence is offered to show IC/BPS forms part of the posterior fornix syndrome (PFS), which was defined in 1993 as: chronic pelvic pain (CPP), urge, frequency, nocturia, abnormal emptying, post-void residual urine, caused by uterosacral ligament (USL) laxity and cured or improved by USL repair. The IC/BPS definition implies that the urge and pain of IC/BPS is from a single (as yet unknown) pathogenic origin. However, when urge and pain are viewed from the perspective of the PFS, though both have the same lax USL origin, the anatomical pathway from lax USL to symptom manifestation is very different manifestation. For CPP the anatomical pathway is the inability of loose USLs to support pelvic visceral plexuses (VPs); it is hypothesized that inability of weak USLs to mechanically supports VPs, the afferent nerve synapse from end organs may fire off autologous afferent impulses to the brain which interprets them as pain from end organs such as urothelium, vulva, lower abdomen. For urge, the anatomical pathway is very different: lax USLs weaken the directional pelvic muscle forces which stretch the vagina to support the urothelial stretch receptors. The receptors fire off afferent impulses to the cortex at a lower bladder volume, and these are interpreted as "urge to go". Mechanical support of USLs relieves both pain and urge, as does USL repair.

Cure of Interstitial Cystitis and Non-Ulcerating Hunner's Ulcer by Cardinal/Uterosacral Ligament Repair.

A serendipitous cure in a 73-year-old woman of Hunner's ulcer, urge, nocturia, apical prolapse by a tissue fixation system tensioned minisling (TFS) which reinforced the cardinal, and uterosacral ligaments (USLs) led us to analyse the relationship between Hunner's ulcer and known pain conditions associated with USL laxity. The original intention was to cure the "posterior fornix syndrome" (PFS), uterine prolapse, and associated pain and bladder symptoms by USL repair. A speculum inserted preoperatively into the posterior fornix alleviated pain and urge symptoms, by mechanically supporting USLs. Hunner's ulcer, along with pain and other PFS symptoms were cured by USL repair. The concept of USL laxity causing chronic pelvic pain and bladder problems is not new. It was published in the German literature by Heinrich Martius in 1938 and by Petros in the English literature in 1993. These findings raise important questions. As PFS symptoms are identical with those of interstitial cystitis (IC), are PFS and IC similar conditions? If so, then patients with IC who have a positive speculum test are at least theoretically, potentially curable by USL repair. These questions need to be explored.

Aromatized arborane/fernane hydrocarbons as biomarkers for cordaites.

Previous palaeobotanical and palynological studies on coals from Euramerican Pennsylvanian ( identical with Late Carboniferous) coal basins indicate a major change in coal-swamp floras, especially at the Westphalian-Stephanian ( approximately Kasimovian-Gzhelian, according to Geological Time Scale 2004) boundary. A flora dominated by arborescent lycophytes was replaced by a vegetation dominated by marattialean tree ferns in various Euramerican coal basins. Earlier combined palynological and organic geochemical studies on Westphalian/Stephanian coals and shales from the Saar-Nahe Basin (Germany) revealed that the distribution of aromatized arborane/fernane hydrocarbons in solvent extracts reflects the increasing importance of seed plants, especially cordaites (extinct group of gymnosperms), conifers and pteridosperms. However, the biological source of the precursor molecules could not be specified. To clarify if the arborane/fernane derivatives MATH, MAPH, DAPH 1, and DAPH 2 in Westphalian/Stephanian coals can be assigned to one of the three potential source plant groups, we analyzed coals, sediments and fossil plant remains from different Euramerican locations with respect to their biomarker composition and stable carbon isotopic composition. Thereby, stable carbon isotopic ratios showed only insignificant variations between Westphalian and Stephanian samples and proved to be an unsuitable tool to describe floral changes during the Westphalian/Stephanian of the Saar-Nahe Basin. In contrast, we were able to show for the first time that MATH, MAPH, DAPH 1 and DAPH 2 are prominent constituents only in extracts of cordaitean macrofossils and can therefore be regarded as biomarkers for this group of gymnosperms.
