Self-regulation method: psychological, physiological and clinical considerations. An overview

Body-oriented therapies as relaxation training and certain forms of meditation are gaining popularity in the treatment and prevention of psychosomatic disorders. In this paper, a new method of self-control called self-regulation method (SRM), derived from autogenic training and Zen meditation, is presented. The technique of SRM is introduced. Secondly, physiological studies on SRM using skin temperature, galvanic skin response, and cortical evoked potentials are presented. Thirdly, the results of psychological tests conducted on SRM are presented. These psycho-physiological studies suggest that SRM may elicit a state of 'relaxed alertness'. Fourthly, clinical applications of SRM are discussed, and 3 cases are presented. Finally, SRM is discussed in relation to the psychology and physiology of 'relaxed alertness'.     

Molecular cloning and expression analysis of a macrophage-colony stimulating factor receptor-like gene from rainbow trout, Oncorhynchus mykiss

The M-CSF and its receptor (M-CSFR, CSF-1R or c-fms proto-oncogene) system were initially implicated as essential in mammals for normal monocyte development as well as for pregnancy. To allow a comparison with the M-CSF and M-CSFR system of an oviparous animal, we cloned a M-CSFR-like gene from rainbow trout (Oncorhynchus mykiss). The gene was cloned from a cDNA library of head kidney. It contained an open reading frame encoding 967 amino acids with a predicted size of 109 kDa. The putative amino acid sequence of rainbow trout M-CSFR showed 54% amino acid identity to fugu (Takifugu rubripes) M-CSFR, 52% to zebrafish (Danio rerio) M-CSFR and 40% to mouse (Mus musculus) and human (Homo sapiens) M-CSFR. The M-CSFR-like gene was constitutively expressed in head kidney, kidney, intestine, spleen and blood. The gene was detected especially in the ovary of immature female rainbow trout. These results suggest that a M-CSFR-like receptor may be involved in female reproductive tracts even in an oviparous animal like fish.     

Epstein-Barr virus-related Hodgkin's disease showing B cell lineage in an immunosuppressive patient seropositive for HTLV-I

A case of Hodgkln's disease (HD), lymphocyte depression (LD) type In an Immunosuppressive patient is described. The patient was a 48-year-old male and his parents were born In the Kyushu area, which is an endemic area for adult T cell lymphomaheukemla (ATL). He was seropositive for ATL virus (ATLV, also referred to as HTLV-I) and showed a marked Immunosuppressive condition. He developed LD-HD and Pneumocystis carinii pneumonia, and died due to respiratory failure. The Immunohistochemical and in situ hybridization analyses revealed that the Reed-Sternberglike cells In the lymph node biopsy sample were positive for Ber-H2 (CD30), Leu-M1 (CD15), L-26 (CD20), Bcl-2, p53 and EBER, the viral genome of Epstein-Barr virus (EBV).     

Knee Flexion Angle Following Total Knee Arthroplasty Relates to a Preoperative Range of Motion of the Hip

BackgroundMany factors have been reported to affect postoperative range of knee flexion after total knee arthroplasty (TKA); however, no study has reported the impact of preoperative range of motion of the hip to the postoperative flexion angle of the knee thus far.MethodsOf 38 consecutive patients who underwent posterior-stabilized TKA, we assessed 21 patients after excluding 17 patients who met exclusion criteria. The range of motion of the knee and the hip, age, body-mass index, serum albumin level, HbA1c, Kellgren–Lawrence grade, knee extension strength and radiological femorotibial angle as well as postoperative knee flexion angle at three months were evaluated. The preoperative data and the knee flexion angle at three months after TKA were compared using Spearman''s rank correlation coefficient.ResultsKnee flexion angle at three months after TKA was positively correlated with preoperative flexion (ρ = 0.616, p = 0.007) and external rotation angle (ρ = 0.576, p = 0.012) of the hip as well as preoperative knee flexion angle (ρ = 0.797, p = 0.001). There were no correlations between postoperative knee flexion angle and other preoperative data.ConclusionsPatients with restricted flexion and/or external rotation of the hip may have contractures of Gluteus maximus, Gluteus medius and Tensor fasciae latae, which can cause hypertension of iliotibial tract. It may cause decreased internal rotation of the tibia when the knee is flexed, which affects postoperative knee flexion angle, thus limited flexion and/or external rotation of the hip might restrict knee flexion angle following TKA.     

Hereditary pressure-sensitive neuropathy: demonstration of "tomacula" in motor nerve fibers.

By studying intramuscular nerves in 2 patients from 2 families with hereditary pressure-sensitive neuropathy (HPSN), the occurrence of abnormal thickening of myelin sheaths ("tomacula") was for the first time demonstrated in motor nerve fibers. Furthermore, the tomacula were found to line up on certain axons instead of being randomly distributed. These results indicate that the recurrent mononeuropathies of HPSN arise from an underlying asymptomatic motor and sensory polyneuropathy. It is also suggested that some signals emanating from the axons might be related to the formation of tomacula on the basis of the genetically determined myelination disorder.     

Urinaryα 1 as an index of proximal tubular function in early infancy

Urinary ₁-microglobulin (U-A₁M) was measured in healthy term infants on days 1, 4, 7, 14, 28, 90 and 180 of life. U-A₁M was high until day 14 and declined thereafter. It was significantly correlated with urinary ₂-microglobulin (U-B₂M) throughout the study, but not with serum A₁M on days 1 or 7. Similar to U-B₂M, U-A₁M in the clinically stable term infants with intrauterine growth retardation (n=4–7) was not elevated on days 1–7. In the sick infants who needed immediate resuscitatio at birth (n=4–8), U-A₁M as well as U-B₂M was high on days 1–7 and then decreased to normal levels, suggesting that U-A₁M can be used as a sensitive marker of acute proximal tubular damage and its recovery. These observations indicate that U-A₁M is a useful index of proximal tubular function in early infancy.     

Isolated avulsion fracture of the lesser tuberosity of the humerus: A case report

Isolated avulsion fractures of the lesser tuberosity are extremely rare. A 24-year-old woman fell on her back as her arm was forcibly extended and adducted. Radiographs revealed a small fragment of bone beneath the glenoid. Axillary radiography showed the bone fragment and a bone defect of the lesser tuberosity. Computed tomography scan clearly demonstrated those findings. Surgery was performed 3 weeks after the occurrence of the injury. The bone fragment was reduced and fixed by means of two screws. After 3 weeks, light exercise was started. At follow-up 7 months later she had no complaints. Most reported cases involved sudden contraction of the subscapularis tendon. This type of fracture is sometimes misdiagnosed; computed tomography scan is useful for diagnosis. Previously reported cases have similarly demonstrated a good outcome after surgery, except in cases involving children.     

Surgical and preoperative treatment of soft tissue sarcoma

Preoperative therapy effects, resected margin and local radicality were investigated in 40 cases of soft tissue sarcoma in which preoperative therapy (mainly radiation therapy) had been given. The results indicated that there was no effect upon prognosis due to postponement of surgery in order to perform preoperative treatment. In cases in which radiation therapy was used for preoperative treatment, even when a surgical margin resulted with in a tumor, no recurrence was found. However, histologically there was concern that some portion of the living tumor cell in marginal area of the tumor might have remained. Thus, at the present stage in cases having undergone initial treatment, radiation limited to the specific area of the resected margin causing non-curative margin should be given. If combined with preoperative radiation therapy, surgical intervention involving "wide margin" can be considered radical. On the other hand, cases having undergone surgery before and receiving preoperative therapy that show good response nevertheless show numerous recurrences. These recurrences, however, invariably occur outside of the irradiated area, and may be attributed to the fact that tumor cell dissemination from the earlier surgery was not within the radiation field. Hence, it was considered that the area for radiation in the case of a recurrence should extend well beyond the scar area.     

Clinical results and prognostic factors of radiotherapy for bone metastases from breast cancer

The purpose of this study was to analyze the results of initial radiotherapy for bone metastases (BM) from breast cancer and to investigate the prognostic factors. Between 1981 and 1995, 65 women (109 lesions) received initial radiotherapy for BM, aiming at a total dose of 50 Gy/25 Fr. Significant relief of pain was obtained in 61 (88.4%) of 69 estimable lesions according to the RTOG score. The control rates of pain including the prevention of pathological fractures or myelopathy were 80.4% at 5 years and 64.3% at 10 years. The median survival time of all patients was 11 months, and the survival rates were 56% at 1 year, 31.6% at 3 years, 17.9% at 5 years and 10.7% at 10 years, with five long-term survivors. Univariate analysis showed that a normal state of LDH, no other metastatic organs, a disease-free interval longer than two years, good performance status (0 or 1), BM limited to the axial bones, maintenance chemo-hormonal therapy and an age of more than 55 years were good prognostic factors. Multivariate analysis showed that LDH, age and performance status were significant predictors of prognosis. It is important to note the prognostic factors at the initial treatment of BM from breast cancer. We consider that further prospective studies are needed to determine the optimal treatment schedule, including radiotherapy and its combination with chemohormonal therapy, for BM.     

Case report of 14-year survival after radiotherapy for clinical T3 esophageal carcinoma, with local recurrence finally rescued by surgery

A 51-year-old man with increasing dysphasia was admitted to our hospital on March 18, 1985. Several examinations revealed thoracic esophageal squamous cell carcinoma 11 cm in length staged T3N0M0 (stage IIA) by UICC 1987. As he rejected our proposal of surgery, definitive radiotherapy (60 Gy) was delivered, and complete response was obtained. The patient had been doing well for 5 years after radiotherapy until superficial local recurrence was discovered at a periodic endoscopic examination. High-dose-rate intraluminal brachytherapy (10 Gy/2 Fr) was administered. After a 3-year disease-free interval, superficial recurrence developed in the same location, and early gastric cancer was detected as a secondary cancer. Radical salvage surgery was performed. The patient was alive and disease free 5 years and 5 months after surgery. We present this rare case of a patient who survived 14 years after the initial radiotherapy. The present case demonstrated the importance of long-term follow-up after radiotherapy, long-term local controllability of relatively low doses of intraluminal brachytherapy after superficial recurrence, and the feasibility of salvage surgery as long as local recurrence is limited to within the mucosal layer.
