Adding Rib Mobilization to Diaphragm Release Techniques in Patients With Non-Specific Neck Pain: Randomized Controlled Trial.

BACKGROUND: Non-specific neck pain (NSNP) is a frequent issue that can negatively affect both mobility and function. Recently, there has been growing interest in newer therapeutic approaches, including rib mobilization and diaphragm release techniques, as potential ways to address NSNP and support better outcomes for those affected. PURPOSE: To find out the immediate effects of how (DRT) combined with (RMT) affects the level of pain and the extent to which patients' functional abilities are improved in cases of NSNP. METHODS: For this prospective RCT, 96 participants aged 20 to 45 years were randomly assigned to one of three equal groups based on their pain score (VAS). Group B engaged in (DRT) for 40 minutes, three times weekly for 8 weeks, in contrast to Group A, which got both RMT combined with DRT. Group C (active control) received advice and some exercises. Measurements were collected before and after the intervention; the primary outcomes included pain severity, evaluated using a visual analog scale (VAS); active neck range of motion (ROM), measured with a cervical range of motion (CROM) device; and neck flexion endurance. Additionally, the secondary outcome of neck-related disability was assessed using the Neck Disability Index (NDI). RESULTS: No statistically significant difference was identified among the three groups at baseline; nevertheless, a treatment effect emerged after 8 weeks (p = 0.001 and f-value = 4.15, ƞ2 = 0.306). A statistically significant time-treatment interaction was seen when comparing the pre- and post-treatment periods in groups A and B (p = 0.001, f-value = 3.16, ƞ2 = 0.251). CONCLUSION: The addition of rib mobilization to diaphragm release techniques in patients with non-specific neck pain resulted in statistically significant improvements in pain intensity, cervical flexion, right lateral rotation, left lateral rotation, right rotation, and neck flexor endurance, with moderate to large effect sizes for pain reduction and cervical motion. However, no statistically significant differences were observed between groups for cervical extension, left rotation, or the Neck Disability Index (NDI), and only a marginal clinical improvement in NDI was noted in Group A. The observed benefits in the combined intervention group may not be attributable solely to rib mobilization. The increased treatment complexity and greater therapist interaction inherent in the combined approach could also have influenced the outcomes.

[The painful floating-rib syndrome].

Attention is drawn to a painful syndrome in the front of the chest, due to abnormal mobility of a rib that has lost the normal cartilaginous connection with that above it. The syndrome is common enough, though little understood. Deep, continuous, dull and gravative pain is felt in the bottom of the chest and top of the abdomen, with distribution over the base of the hemithorax involved. It is relieved by rest and exacerbated by the effort and certain postures. One or more ribs on one or both sides may be affected, though the Xth is most commonly concerned. The condition may be the direct or indirect result of trauma, or congenital. Abnormal development of the XIth rib may result in its riding over that above it and so causing pain. The formation of parietal algogenous sites is thought to be primarily responsible for pain. These sites result from rubbing of the end of the free cartilage on neighbouring structures. Direct compression of the corresponding trunk may also be involved. Objective diagnosis is based on topical signs. The floating rib is readily recognised as the cause of pain and the syndrome itself is known as the painful slipped (better, floating) rib syndrome. Satisfactory results are obtained by deep analgesic infiltration at the end of the free cartilage and can be prolonged by rest. Reference is made to previously reported data concerning functional disorders of the extrahepatic bile ducts in subjects with this syndrome in the light of a more ample case series. The radiological picture is usually marked by gall bladder hypertonia and hyperkinesis, with occasional sphincter involvement. The physiopathogenetic interpretation of these associated parietobiliary manifestations is discussed in the light of experimental and therapeutic evidence. Their clinical interest is also stressed.

The changes in configuration of the rib cage and abdomen during breathing in the anaesthetized cat.

1. The external surface of the rib cage and abdominal wall in anaesthetized cats was surgically exposed in order to record their movements cinematographically in spontaneous breathing and in paralysed cats, during artificial positive pressure ventilation. 2. Cine-stereophotography was used to allow the recording of the movements of a set of markers placed on the external surface of the trunk wall and the corresponding stereometric data were numerically and graphically processed into three-dimensional drawings. The cine-film frames corresponding to the phases of maximum inflation and deflation of the lungs were analysed to reveal the changes in configuration associated with the respiratory movements of the trunk wall. 3. The changes in shape of the diaphragm and the diaphragm and the displacements of the abdominal viscera between extreme inflation and deflation were recorded by X-ray photography. 4. During spontaneous inspiratory movements, the ribs rotated outwards and rostrally about the costovertebral joints, bringing about an increase in the transverse dimensions of the cage all along its length; these movements were accompanied by a clear-cut caudad displacement of the sternum, caused by the straightening of the costal cartilages and by the widening of the angles defined at sternochondral joints between the sternum and each of the costal cartilages. 5. Neuromuscular blockade abolished muscle tone in the trunk wall, allowing the weight of the viscera markedly to deform its configuration. 6. The inspiratory rib movements of the paralysed animal during artificial inspiration were similar to those during spontaneous breathing but the movements of the sternum were inverted and showed small cranial displacements. 7. The loss of muscular tone under neuromuscular blockade made the abdominal wall more compliant than the rib cage to the positive lung pressure and allowed greater mobility of the viscera with consequent distortion of the shape of the diaphragm. 8. The role of rib cage muscle tone in meeting requirements of purely configurational character in such a shell-like structure is discussed in relation to the optimal mechanical performance of the diaphragm.

ADP ribosylation of rat liver nucleosomal core histones.

When nucleosomal core histones were isolated from rat liver nuclei incubated with [14C]NAD+ and fractionated into the individual components (H2A, H2B, H3, and H4), [14C]adenosine diphosphate ribose (ADP-Rib) was found to be associated with all of them. However, while about 15% of the H2B molecules were modified, less than 2% of the other fractions contained radioactive ADP-Rib. The nucleotide attached to H2B was identified as a single monomer of ADP-Rib. On subjectint H2B to electrophoresis in polyacrylamide gels containing 2.5 M urea and 0.9 N acetic acid, one single band of H2B with 5% less mobility than the unomdified control was obtained. The linkage between H2B and ADP-Rib was rapidly hydrolyzed with 0.1 N NaOH or with 1 M neutral hydroxylamine. Hydrolysis of ADP-ribosylated H2B with trypsin generated a single peptide linked to ADP-Rib, which corresponded to the sequence Pro-Glu-Pro-Ala-Lys. We were able to dansylate the NH2-terminal proline, which proved that the imino group of this amino acid was not substituted. These findings, together with the chemical properties of the linkage, which were typical of those of an ester-like bond, strongly suggest that the ADP-Rib residue was linked to the gamma-COOH group of the glutamic acid in position 2 of H2B.

ADP ribosylation of rat liver lysine-rich histone in vitro.

Purified rat liver nuclei were incubated with [14C]-NAD+ and the various nuclear protein fractions were separated. Forty per cent of the total radioactivity incorporated was associated with the histone fraction. Of this, about 50% was extracted with H1, in 0.5 N perchloric acid. When crude H1 was purified and fractionated into five different subfractions by chromatography on Bio-Rex 70, it was found that all the H1 subfractions contained radioactivity. This radioactive material was identified as oligomers of adenosine diphosphate ribose (ADP-Rib) with an average chain length which corresponded to trimers. The extent of the modification was dependent on the concentration of NAD+. About 60% of the H1 molecules were modified with a concentration of 1 mM NAD+. The presence of these oligomers of ADP-Rib introduced a large degree of microheterogeneity to H1 as detected by electrophoresis in polyacrylamide gels containing 2.5 M urea and 0.9 N acetic acid. Bands of H1 with 10 to 20% less mobility than the unmodified H1 were present. Also, as a consequence of large content of ADP-Rib, the absorption maximum shifted from 275 to 259 nm. The half-life of the bond between the oligomers of ADP-Rib and H1 was about 3 min at 37 degrees C in the presence of 0.1 N NaOH, and 10 m1 were modified. The site of ADP ribosylation in the NH2-terminal half was localized in the tryptic peptide extending from the NH2-terminal end to lysine 15. The site of modification of the COOH-erminal half was localized in the tryptic peptide which contained the only glutamic acid residue in this fragment of H1...

Podocytes of rat kidneys with nephrotoxic serum nephritis. A combined transmission and scanning electron microscopic study.

Rats with a nephrotoxic serum nephritis reveal changes of proteinuria and content of serum proteins as well as serum cholesterol in the direction of a nephrotic syndrome as is seen after Daunomycin. Nevertheless, the morphological findings with TEM and especially with SEM are quite different. A striking feature of the nephritis is the rather good preservation of cell processes through all the time of experiment in spite of the elevated proteinuria. Moreover, podocytes with furrowed or ribbed surfaces originate and are most numerous when the signs of inflammation are most pronounced. These furrowed podocytes are interpreted as representing a special reactive, perhaps mobilized form. With SEM it is evident that the glomeruli are altered focally and segmentally in the nephrotoxic serum nephritis.

Mandibular reconstruction with bone grafts.

A total of 23 patients with partly resected mandible were repaired with autogenous bone grafts from the iliac crest and ribs. The reasons for reconstruction are presented in Table 1. The grafts healed without complications in 21 cases. With the exception of two of the cases with gunshot wounds, all patients recovered good mobility of the jaw and satisfactory mandibular contours. The patients had been folloed up for 6 months to 11 years. Radiographic examination at the last examination showed that resorption of the graft had been only slight or moderate. Through marrow-spongious bone grafts are regarded as best from an osteogenetic point of view, our cases showed that good results can be achieved also with solid block grafts. The authors discuss the use of plate osteosynthesis without IMF instead of other types of graft fixation and IMF. In six cases where the area of the graft was loaded with a prosthesis, resorption was not more extensive than in the other cases.

Marlex mesh support for the correction of very severe and recurrent pectus excavatum.

A method for the correction of very severe and recurrent pectus excavatum is presented. The technique consists of mobilization of the sternum, transverse osteotomy, parasternal resection of the costal cartilages (modified Ravitch procedure), followed by placement of Marlex mesh behind the sternum and suturing the edge of the Marlex mesh to the peripheral stump of the resected ribs. This method has been used with good results in 6 patients, 2 of them with recurrent deformities.

Microsurgical composite tissue transplantation.

Since 1974, 69 patients with extensive defects have undergone reconstruction by microsurgical composite tissue transplantation. Using this method, donor composite tissue is isolated on its blood supply, removed to a distant recipient site, and the continuity of blood flow re-established by microvascular anastomoses. In this series, 56 patients (81%) were completely successful. There have been eight (12%) failures, primarily in the extremities. There have been five (7%) partial successes, (i.e., a microvascular flap in which a portion was lost requiring a secondary procedure such as a split thickness graft). In those patients with a severely injured lower extremity, the failure rate was the greatest. Most of these were arterial (six of seven). These failures occurred early in the series and were thought to be related to a severely damaged recipient vasculature. This problem has been circumvented by an autogenous interpositional vein graft, permitting more mobility of flap placement. In the upper extremity, all but one case were successful. Early motion was permitted, preventing joint capsular contractures and loss of function. Twenty-three cases in the head and neck region were successful (one partial success). This included two composite rib grafts to the mandible. Prolonged delays in reconstruction following extirpation of a malignancy were avoided. A rapid return to society following complete reconstruction was ensured. Nine patients presented for reconstruction of the breast and thorax following radical mastectomy. All were successfully reconstructed with this new technique except one patient. Its many advantages include immediate reconstruction without delayed procedures and no secondary deformity of the donor site. Healthy, well vascularized tissue can now be transferred to a previously irradiated area with no tissue loss. This new method offers many advantages to older methods of reconstruction. Length of hospital stay and immobilization are reduced. The total number of operative procedures required in achieving the desired result is also less, thus decreasing the cost of hospital care.

[Research concerning the physiopathology of post-traumatic periarticular ossifications and anterior brachial muscle osteoma. Their prevention].

The author maintains that the osteoma of the brachial muscle as well as post-traumatic periarticular calcifications, occur in the muscle mass or in the tendon that prolongs it, or in the articular capsule, as a result of surgical treament and post-operative immobilization, and only exceptionally following orthopaedic treatment of traumatic lesions. Articular mobilization in the first week after osteosynthesis, or in the frame of conservative treatment, is not followed by osteoma of the brachial muscle or by calcifications surrounding the articulation, a fact that suggest that the presently applied therapeutic methods, which recommend strict and prolonged articular immobilization should be avoided. The development of ossification can be explained by post-traumatic changes in the muscular microcirculation, rendered more severe by surgical treatment and maintained by muscular inactivity. Early articular mobilization is the most efficient method of prophylaxis of these complications, which are determined not by the traumatic lesions themselves but by the present therapeutic methods applied.

Effect of dichloromethane diphosphonate on calcium homeostatic mechanisms in pregnant cows.

The administration of 4 mg/kg/day of dichloromethane diphosphonate (Cl2MDP) subcutaneously to pregnant cows fed a low-calcium diet significantly reduced bone resorption as indicated by microradiographic evaluation of endosteal surfaces of cross sections of ribs. Plasma parathyroid hormone levels were similar between Cl2MDP-treated and control cows prepartum, during EDTA infusions, and near parturition. Ultrastructurally, chief cells of the parathyroid glands of both groups of cows were in the active stage of the secretory cycle. The chronically stimulated chief cell from cows administered Cl2MDP had a large cytoplasmic area containing many lipofuscin granules and lysosomal bodies and a few secretory granules near the large Golgi apparatus or aligned along the plasma membrane. Uptake of calcium 45 by the duodenal mucosa incubated in vitro was greater in Cl2MDP-treated cows compared to control cows. The administration of Cl2MDP significantly reduced rapidly mobilization calcium reserves. Following an intravenous EDTA infusion and the spontaneous calcium drain associated with parturition and the beginning of lactation, Cl2MDP-treated cows developed severe hypocalcemia. The rapid mobilization of calcium reserves in cows administered Cl2MDP prepartum was impaired mainly because of diminished resorption of bone despite adequate parathyroid hormone secretion in response to severe postpartal or EDTA-induced hypocalcemia.

[Ribosomal dysentery vaccine. III. An immunochemical and serological study].

Sh. sonnei rib oscmes, isolated by differential centrifugation, were previously shown to be highly protect ive against experimental keratoconjunctivitis in guinea pigs. Immunochemical study showed that ribosomal preparations were not uniform in their antigenic composition: as a result of immunoelectrophoretic analysis with the use of anti-ribosomal hyperimmune rabbit antisera, these preparations were found to contain up to 4 antigenic components with different migration rate. The anodic component with the highest elections obtained by the method of Boivin and Grasset and could be inactivated at 60 degrees C or by treatment with trypsin or RNA-se, which suggested its ribonucleoprotein nature. The second thermolabile antigenic component was found to have a moderate anodic mobility and, judging by the results of enzymatic treatment, seemed to be protein. Other antigens with low mobility were resistant to trypsin and RNA-se; one of them, forming a weak precipitation line, could be identified as endotoxin by its antigenic specificity. The use of tanned and ribosome-coated erythrocytes allowed to determine the level of antiribosomal antibodies in the passive hemagglutination test and to evaluate the serological activity of ribosomal preparations in the hemagglutination inhibition test (the minimum inhibiting concentration of ribosomes was 1--2 microgram/ml). The specificity of serological reactions was mainly determined by a highly mobile nucleoproteid component.
