Analysis of the circumstances at the end of life in children with cancer: Symptoms, suffering and acceptance

BACKGROUND: In an effort to improve the quality of life of children with cancer, this study analyzes the signs and symptoms at the end of life in such children. It is hoped that these data will contribute to the development of appropriate programs to address the challenges faced by these children. PROCEDURE: Between 1994 and 2000, 28 children died after treatment for cancer at Hamamatsu University Hospital, Japan. The circumstances, signs and symptoms at the end of life of these children were analyzed through their medical records. RESULTS: Of the 28 children, the underlying diseases were leukemia/lymphoma (LL group; n=11), brain tumors (BT group; n=7), and other solid tumors (OST group; n=10). Records showed poor appetite (100%), dyspnea (82.1%), pain (75.0%), fatigue (71.4%), nausea/vomiting (57.1%), constipation (46.4%) and diarrhea (21.4%) among these children. Anxiety was reported in 53.6% of the entire group of 28 children; however, no child in the BT group manifested anxiety. However, disturbance of consciousness was reported in all children in the BT group, which was significantly greater than in the other groups. Awareness, fear or acceptance of the imminence of his/her own death as indicated by verbal expression was reported in nine children (32.1%). CONCLUSIONS: Using the data obtained in the present study, we describe situations faced in the terminal care of children. It is important to address the problems revealed by this analysis in order to achieve improvements in both the physical and psychological care of children with terminal cancer.     

Epidemiological survey of foot diseases in Japan: Results of 30 000 foot checks by dermatologists

There has been no epidemiological survey of foot diseases in Japan. In this study we determined the prevalence of foot diseases, especially tinea pedis (TP) and tinea unguium (TU) in Japan. We conducted a randomized survey of outpatients who visited a dermatologist during the third week of May in 1999, 2000 and 2006. The most frequently reported condition was “fungal infection” in 8737 (40.0%) of 21 820 patients in 1999/2000, and 3848 (49.4%) of 7783 patients in 2006. The patients who visited a dermatologist for reasons other than superficial fungal infection but were diagnosed with TP or TU comprised 18.6% of the study population in 2000 and 24.1% in 2006. Of the patients with TP or TU, 63.2% used topical medication only. This survey showed that often patients are not aware of fungal infections and that their treatment is sometimes insufficient. Dermatologists should actively examine and treat patients with TP and TU.     

Excellent Clinical Results with a New Preparation for Chemical Peeling in Acne: 30% Salicylic Acid in Polyethylene Glycol Vehicle

BACKGROUND Chemical peeling by salicylic acid in ethanol or another vehicle may be accompanied by stinging and burning followed by postinflammatory hyperpigmentation in the treated area, or salicylism. We have developed a new formulation: 30% salicylic acid in polyethylene glycol (SA-PEG). A topical application of SA-PEG remodels photodamaged skin in mice and humans, without systemic absorption.
OBJECTIVE The objective was to evaluate the safety and efficacy of SA-PEG for clinical use in the treatment of acne.
MATERIALS AND METHODS We evaluated the effects of the preparation histologically in mice and its safety and efficacy in 44 volunteers with normally aged skin and in 436 patients with acne.
RESULTS Histologic studies in animals showed no inflammatory changes in the skin following topical application of SA-PEG. Volunteers noted an improved skin texture. In the acne patients, the comedones and papules disappeared, resulting in an excellent outcome. There was a notable absence of stinging and burning, edema, bleeding, or crusting in the treated area.
CONCLUSION The SA-PEG preparation appeared to be safe and effective, with minimal associated inflammation or adverse effects, even in Asian patients who tend to develop hyperpigmentation or keloids. This preparation is thus ideal for chemical peeling.     

Characterization and Modification of Brain Activity with Deep Brain Stimulation in Patients in a Persistent Vegetative State: Pain-Related Late Positive Component of Cerebral Evoked Potential

A series of eight patients in a persistent vegetative state (PVS) were subjected to chronic deep brain stimulation (DBS) for the purpose of promoting recovery from the PVS. The characteristics of the brain activity in these patients were evaluated from the late positive component of the cerebral evoked potential in response to painful stimuli (pain-related P250). While any neurological scoring system for the comatose state includes evaluations of motor reactions to painful stimuli, the pain-related P250 is unique in terms of its ability to assess the cortical responsiveness to painful stimuli directly and quantitatively without involving functions of the motor system. It was found that the pain-related P250 was more or less depressed in patients in a PVS. It was repeatedly demonstrated in four patients, however, that the pain-related P250 could be transiently increased by preceding stimulation of the mesencephalic reticular formation. Furthermore, a persistent increase in the pain-related P250 was produced in these four patients following chronic DBS of the mesencephalic reticular formation or nonspecific thalamic nuclei for more than 6 months, and this was correlated with the clinical improvements. These results imply that responsiveness at the cortical level to pain is depressed in the PVS. It also appears that some fraction of the depression may, however, be functionally produced and potentially reversible.     

Unusually located lymphocutaneous nocardiosis caused by Nocardia brasiliensis

Summary We report a patient with primary lymphocutaneous Nocardia brasiliensis infection affecting the face and left arm. The mode of infection was via skin abrasions which occurred 2 weeks prior to the development of the skin lesions. Treatment with intravenous minocycline for 4 weeks resulted in a cure. We also review 12 previously reported Japanese cases of lymphocutaneous nocardiosis.     

TWO TYPES OF THYROID FUNCTION-BLOCKING ANTIBODIES IN AUTOIMMUNE ATROPHIC THYROIDITIS AND TRANSIENT NEONATAL HYPOTHYROIDISM DUE TO MATERNAL IgG

We examined the effects of IgG from four patients with autoimmune atrophic thyroiditis on cAMP responses and iodine metabolism (post-receptor processes), using cultured thyroid cells. We found two types of thyroid function-blocking antibodies: (1) one blocks TSH binding to its receptors and inhibits TSH-stimulated cAMP responses but does not block cAMP-stimulated iodine uptake and organification; (2) the other blocks TSH binding to its receptors, inhibits TSH-stimulated cAMP responses and does block cAMP-stimulated iodine uptake and organification (post-receptor processes). Among the four patients with autoimmune atrophic thyroiditis, three had TSH binding blocking antibodies only and one had antibodies which block post-receptor processes. These antibodies might be responsible for thyroid dysfunction in autoimmune atrophic thyroiditis. The daughter of one of the women with autoimmune atrophic thyroiditis had transient neonatal hypothyroidism and recovered spontaneously from the hypothyroid state with the disappearance of the maternal blocking antibodies.     

Longitudinal change in youth suicide mortality in Okinawa after World War II: A comparative study with mainland Japan

Abstract Okinawa prefecture has a unique socio-cultural status in Japan including the experience of having been occupied by the USA from the end of World War II to 1972. In this study, the longitudinal change in youth suicide mortality for those aged 10–29 years in Okinawa (1960–90) was compared with that for the same sex-age groups in mainland Japan (1950–90). In contrast with mainland Japan, no dramatic change in the youth suicide mortality was observed in Okinawa in the 1960s. The rise and fall of teenage suicide mortality in Okinawa during the 1970–80s might be associated with 'reversion anxiety', rather than with the traumatic experience of World War II itself. This seems to be inconsistent with previous speculation regarding the change in youth suicide mortality in mainland Japan. The suicide mortality for men aged 20–29 in Okinawa was significantly higher than that for the same sex-age group in mainland Japan through the observed period. The possible effects of the USA occupation, economic anomie or migration on the suicide in Okinawa should be further examined.     

Detection of oral streptococci with collagen‐binding properties in saliva specimens from mothers and their children

International Journal of Paediatric Dentistry 2010; 20: 254–260 Background. Approximately 10–20% of Streptococcus mutans strains have been reported to possess collagen‐binding properties, whereas other species in the oral cavity with those properties remain to be elucidated. Aim. To identify strains with collagen‐binding properties and analyse their characteristics in comparison with S. mutans. Design. A total of 110 expectorated saliva specimens were collected from 55 pairs of mothers and their children. Bacterial strains with collagen‐binding properties were isolated and the species specified. In addition, strains with collagen‐binding properties isolated from mother–child pairs were analysed using molecular biological approaches. Results. The detection frequency of strains with collagen‐binding properties was shown to be 40.9%, among which S. salivarius was the most frequently detected, followed by S. mutans. The collagen‐binding activity of the S. mutans group was the highest, followed by S. salivarius. In addition, S. mutans and S. salivarius strains from 3 and 1 mother–child pairs, respectively, were shown to be the same clones. Conclusions. Our results indicate that S. mutans and S. salivarius are major species with collagen‐binding properties in the oral cavity, and that strains with such properties may be related to mother–child transmission.     

Analysis of the circumstances of death of 56 children suffering from cancer: Proposal for the development of terminal medicine in Japan

In Japan terminal medicine for children dying from cancer has not yet been developed nor has a support system for home terminal care and bereaved families been established. We have analyzed our own experiences in these areas and researched the possibilities of establishing support systems. In the 16 years from 1978 to 1993, 56 children with cancer have been treated and have died at Hamamatsu University Hospital. We analyzed the circumstances of their deaths. We interviewed 25 sets of parents about their acceptance of their child's death. Three children (5%) died unexpectedly during treatment, 27 children (48%) died from the side-effects of intensive treatment, and 26 children (47%) died during terminal care. More children with leukemia and lymphoma died from side-effects than children with solid tumors (P < 0.05). Six out of the 25 families had not yet accepted the loss of their child due to regrets associated with the missed opportunity for terminal care. From our experiences with the five children who received terminal care at home, we recognize the need for a support system run by the hospital and conclude the time is ripe for initiating home-based terminal care in Japan.
