Analysis of Two Treatment Modalities for Post-surgical Pain after Hemorrhoidectomy.

This non-randomized study aimed to compare the efficacy of two pharmacological treatments, "around-the-clock" analgesic treatment (ACAT) and "on-demand" analgesic treatment (ODAT), for managing postoperative pain following hemorrhoidectomy. Material and The study, conducted from July 2016 to December 2020, included 5335 hemorrhoidectomy patients. Participants were divided into ACAT (3767) and ODAT (1568) groups.

A Community Social Work Paradigm: Thoughts and Reflections.

Community social work (CSW) is often regarded as a practice with a variety of intervention models. The objectives of the present article are to examine CSW's philosophical and theoretical roots and to bridge the gap in the literature regarding the theoretical and philosophical origins of CSW and to conceptualize these theoretical bases as a paradigm with ontological, epistemological, axiological, and methodological aspects. The ontology of the proposed CSW paradigm relies on ecological theory, critical theory, and community psychology.

From acute stress to persistent post-concussion symptoms: The role of parental accommodation and child's coping strategies.

Acute stress following mild Traumatic Brain Injury (mTBI) is highly prevalent and associated with Persistent Post-Concussion symptoms (PPCS). However, the mechanism mediating this relationship is understudied. To examine whether parental accommodation (i.

[Formula: see text]Persistent post-concussion symptoms in children: pre-injury social difficulties and acute stress reaction as risk factors.

Following mild traumatic brain injury (mTBI) children usually experience one or more somatic, cognitive, and/or emotional-behavioral post-concussion symptoms (PCS). PCS may be transient, however for some children, persistent post-concussion symptoms (PPCS) might linger for months or years. Identifying risk factors for PPCS may allow earlier interventions for patients at greater risk.

Enhancement of factor VIIa haemostatic efficacy by formulation with PEGylated liposomes.

Recombinant activated factor VII (rFVIIa) is an effective treatment of the haemophilia patient with inhibitors and acquired haemophilia. However, on account of its relatively short half-life (HL), achieving therapeutic efficacy with FVIIa requires repeated injections. The development of a long-acting FVIIa product would therefore be beneficial.

Iron(III) corroles and porphyrins as superior catalysts for the reactions of diazoacetates with nitrogen- or sulfur-containing nucleophilic substrates: synthetic uses and mechanistic insights.

A thorough mechanistic investigation has been performed on the reactions of primary and secondary amines with diazoacetates, which proceed uniquely quickly and efficiently when catalyzed by iron(III) corroles and porphyrins. Two major differences in relation to other metal-based catalysts are that the iron complexes are not poisoned by excess amine and that metal-carbene intermediates are apparently not involved in the reaction pathway. The results instead point towards nitrogen ylide intermediates formed by nucleophilic attack of the amines on diazoacetate-coordinated iron complexes.

Corrole-based applications.

Despite of the many similarities between corroles and porphyrins, the chemistry of the former remained undeveloped for decades because of severe synthetic obstacles. The recent discoveries of facile methodologies for the synthesis of triarylcorroles and the corresponding metal complexes allowed for their utilization in various fields. This survey reveals many examples where corroles were used as the key components in catalysis, sensing of gaseous molecules and medicine-oriented research.

Iron porphyrins catalyze the synthesis of non-protected amino acid esters from ammonia and diazoacetates.

Iron complexes of porphyrins (and corroles to a lesser extent) are the first catalysts to utilize ammonia for the synthesis of N-free amino acid esters.

Further aspects of design for distal extension removable partial dentures based on the Kennedy classification.

A supplement to the Kennedy classification of partially edentulous arches for restoration with removable partial dentures has been suggested. Factors affecting denture design relating to the position of the abutment teeth, the symmetry of the edentulous distal extensions, the arch form and the cross-sectional shape of the residual ridges have been discussed and classified. An understanding of the movement of the denture bases in relation to the influence of these factors makes for a rational approach to removable partial denture design and the treatment of complications observed clinically in removable partial denture wearers.

Use of roots to establish favorable removable partial denture design: case reports.

Judicious retention of roots can alter the position of the anterior fulcrum line and so simplify removable partial denture design. Complicated tooth-tissue-supported designs are thus transformed into much simpler tooth-supported removable partial overdentures.

The cantilever fixed partial denture--a literature review.

The cantilever fixed partial denture (FPD) is a restoration with one or more abutments at one end and unsupported at the other end. Forces transmitted through the cantilevered pontics can cause tilting and rotational movements of the abutments. In a cross-arch unilateral cantilever FPD, the distal cantilevered unit is subjected to comparatively less force than the contralateral posterior abutment.

Factors affecting displacement of free-end saddle removable partial dentures.

Tissueward movement of the free-end saddle of a removable partial denture during function takes place around the most distal fulcrum created by the most mesial rests. Displacement because of sticky foods takes place around the fulcrum created by the most distal rests. These and other factors affecting displacement of the free-end saddle removable partial dentures are discussed, and designs intended to increase retention are presented.

RLS--the lingually retained clasp assembly for distal extension removable partial dentures.

The design of clasp for a distal extension removable partial denture that helps preserve both the abutment teeth and the tissues of the edentulous ridge is described. The clasp assembly takes advantage of surveyed lingual undercuts to provide support, retention, and stability. It consists of a mesio-occlusal rest, a distolingual L-bar direct retainer that is located on the abutment tooth adjacent to the residual ridge, and a distobuccal stabilizer (RLS).

Rigidity of major connectors when subjected to bending and torsion forces.

Rigidity tests were performed on maxillary major connectors of different designs and mandibular major connectors of the lingual bar-type with different cross-sectional shapes and thicknesses. Each major connector was clamped on one side while the other side was subjected to bending, torsion, and bending under torsion forces. Deformation was measured with a micrometer microscope.

Photoelastic analysis of stress transfer by endodontically treated teeth to the supporting structure using different restorative techniques.

A photoelastic model was used to examine the influence of different types of restorations placed following endodontic therapy, emphasizing the way in which forces applied to the occlusal surface were dispersed to the supporting structures of the teeth. Stresses were photographed in the polarized light field. Findings indicate that distribution and patterns of stresses vary depending on the direction of the loads and the nature of the involved restorative procedures.

Severe infraclusion ankylosis: report of three cases.

Tooth ankylosis may occur at any time during eruption and may show varying degrees of infraclusion. Cases of fully erupted teeth subsequently becoming totally embedded in bone are rare. The three reports described here show cases of severe infraclusion ankylosis; the etiology and related problems are discussed.

An analysis of rotational movement of asymmetrical distal-extension removable partial dentures.

An axis of rotation is created through the most distally placed occlusal rests when a distal-extension removable partial denture is loaded. If the residual ridges are of unequal lengths, this axis of rotation may not be perpendicular to the residual ridges. The resultant movement of asymmetric denture bases and their effect on the tissues are discussed.

A rapid dowel core construction technique.

The use of composite resins for dowel cementation and core construction is well established. A short, easy, time-saving method is proposed for simultaneous dowel cementation and core fabrication using a composite core construction material.

A modified direct retainer design for distal-extension removable partial dentures.

The rationale for designing a direct retainer for a distal-extension removable partial denture is described. The advantages of an L-bar clasp arm over the I-bar clasp arm are discussed. The retentive surface of an abutment tooth is divided into three zones according to the clasp tip movement and the importance of placing the retentive tip in the zone of vertical movement is emphasized.
