Commonly cited incentives in the community implementation of the emergency maternal and newborn care study in western Kenya

BACKGROUND

Mortality of mothers and newborns is an important public health problem in low-income countries. In the rural setting, implementation of community based education and mobilization are strategies that have sought to reduce these mortalities. Frequently such approaches rely on volunteers within each community.

OBJECTIVE

To assess the perceptions of the community volunteers in rural Kenya as they implemented the EmONC program and to identify the incentives that could result in their sustained engagement in the project.

METHOD

A community-based cross sectional survey was administered to all volunteers involved in the study. Data were collected using a self-administered supervision tool from all the 881 volunteers.

RESULTS

881 surveys were completed. 769 respondents requested some form of incentive; 200 (26%) were for monetary allowance, 149 (19.4%) were for a bicycle to be used for transportation, 119 (15.5%) were for uniforms for identification, 88 (11.4%) were for provision of training materials, 81(10.5%) were for training in Home based Life Saving Skills (HBLSS), 57(7.4%) were for provision of first AID kits, and 39(5%) were for provision of training more facilitators, 36(4.7%) were for provision of free medication.

CONCLUSION

Monetary allowances, improved transportation and some sort of identification are the main incentives cited by the respondents in this context.

Preoperative advantages of HF sonography of pilonidal sinus

Pilonidal sinus is a not infrequent disease, probably due to a disontogenetic origin. Histologically, there is a pseudocystic formation in the subcutaneous adipose tissue, containing some hair bulbs. It usually presents a recurring inflammatory course. The pathologic formation does not normally have thick wall, being made up of thin epidermal epithelium, without internal vascularisation and with frequent subcutaneous fistulae. Even though the clinical diagnosis is rather easy, surgery may prove, on the contrary, a demanding task, with a high incidence of recurrence and complications. An adequate knowledge of the condition and its development, with a precise definition of the margins of the lesions, may simplify the surgery, reducing the chance of recurrence or complications. The use of echography in the diagnosis of this disease, in our cohort of 72 patients, has always provided valuable information. In particular, 13 and 18 MHz linear probes and 20 MHz mechanical array have been used, and the latter in particular for the evaluation of fistolous cavities/passageways under the skin. Results. In all our cases, echography has demonstrated pseudocystic formations, without real walls, with fairly high levels of internal echoes, compared to the hair follicles, or, more rarely, true macrocalcifications with one or more cavities/passageways near the skin, without internal vascularisation, according to the histological findings. Echographic data are rapidly obtained, and can prove useful for surgeons for a a better management of patients. Conclusion. We consider diagnostic echography, using high frequency probes, useful for the anatomical definition of this disease, as well as to enable better surgical management.

Selective lymphadenectomy for penile cancer

INTRODUCTION

Lymph node treatment in patients with penile cancer has been longly debated in the last 15 years, with surgeons advocating therapeutic lymphadenectomy and others advocating selective lymphadenectomy (SLND).

MATERIALS AND METHODS

We evaluated the outcome of clinically node negative penile cancer patients treated with SLND. Since March 2000, 35 node negative penile cancer patients were operated on mainly at the Division of Plastic Surgery, San Gallicano Institute, Rome (Italy), with SLND.

RESULTS

A sentinel node was detected in 34 out of 35 patients (42 groins). With a minimum of five years follow up, metastases were noted in 5 out of 35 patients. Out of the remaining 30 patients, 2 developed node metastases in the operated inguinal region (6.6%).

DISCUSSION

SLND for penile cancer compared to surveillance only greatly improves survival rate and disease-free rate (91% vs 79% after 3 years follow-up). Identification of more specific markers for SCC lymph node metastases will make the false negative-rate drop further.

Cagliari University Hospital (CUH) protocol for immediate alloplastic breast reconstruction and unplanned radiotherapy. A preliminary report

INTRODUCTION

Alloplastic breast reconstruction necessitating postmastectomy radiotherapy (PMRT) is at increased risk for complications such as capsular contracture, infection, extrusion, and poor cosmetic results. However, often the indication for PMRT is not decided until a permanent histological examination with review of the permanent sections is carried out, and the expander has already been inserted. Techniques described to face this issue (delayed-immediate reconstruction and Memorial Sloan Kettering Cancer Center protocol) both have disadvantages.

MATERIALS AND METHODS

The protocol we suggest is based on (1) reconstruction with tissue expander placement at the time of mastectomy; (2) complete tissue expansion during postoperative chemotherapy; (3) radiotherapy, as suggested by oncologists; (4) two or three fat grafting session, according to Coleman's technique, 4-6 months after RT; (5) exchange of the tissue expander for a permanent implant approximately 3 months after the completion of fat grafting. Ten patients were treated according to these guidelines.

RESULTS

Results at 15 months have been encouraging, with no grade 3-4 Baker's capsular contracture.

DISCUSSION

Although the group of patients treated according to our CUH Protocol for immediate implant-based breast reconstruction and radiotherapy is small, and follow-up is short; nevertheless, results are encouraging.

[Radiofrequency ablation as a palliative therapy option in ENT tumors: in vivo and in vitro testing]

BACKGROUND

High frequency thermotherapy (HFTT) is an established palliative therapy for hepatic malignancies. An in vivo and in vitro trial examined the preconditions for the application of HFTT with liquid-cooled wet electrodes for minimally invasive palliation of head and neck tumors.

MATERIAL AND METHOD

HFTT was applied with needle electrodes, cooled with isotonic saline solution, and a high-frequency generator (Elektrotom HiTT 106, Berchtold, Tuttlingen) to porcine tongue and narcotized, juvenile domestic pigs to the tongue and neck, and monitored in realtime by B-mode ultrasound.

RESULTS

The direction of spread of the hyperthermic zone is well observed using ultrasound. Determining the direction of spread is not possible with cooled-tip electrode needles. Severe complications were not observed during the application.

CONCLUSION

RFA with liquid-cooled needle applicators is not safely applicable for the therapy of head and neck tumors.

Host- rather than virus-related factors reduce health-related quality of life in hepatitis C virus infection

BACKGROUND

Hepatitis C virus (HCV) infection is associated with decreased health-related quality of life (HRQOL). Although HCV has been suggested to directly impair neuropsychiatric functions, other factors may also play a role.

PATIENTS AND METHODS

In this cross-sectional study, we assessed the impact of various host-, disease- and virus-related factors on HRQOL in a large, unselected population of anti-HCV-positive subjects. All individuals (n = 1736) enrolled in the Swiss Hepatitis C Cohort Study (SCCS) were asked to complete the Short Form 36 (SF-36) and the Hospital Anxiety Depression Scale (HADS).

RESULTS

833 patients (48%) returned the questionnaires. Survey participants had significantly worse scores in both assessment instruments when compared to a general population. By multivariable analysis, reduced HRQOL (mental and physical summary scores of SF-36) was independently associated with income. In addition, a low physical summary score was associated with age and diabetes, whereas a low mental summary score was associated with intravenous drug use. HADS anxiety and depression scores were independently associated with income and intravenous drug use. In addition, HADS depression score was associated with diabetes. None of the SF-36 or HADS scores correlated with either the presence or the level of serum HCV RNA. In particular, SF-36 and HADS scores were comparable in 555 HCV RNA-positive and 262 HCV RNA-negative individuals.

CONCLUSIONS

Anti-HCV-positive subjects have decreased HRQOL compared to controls. The magnitude of this decrease was clinically important for the SF-36 vitality score. Host and environmental, rather than viral factors, seem to impact on HRQOL level.

[A case of vulvar melanoma: surgical strategy and five years follow-up]

We report a case of a woman with vulvar melanoma, arisen from a plane melanocytic lesion, extended from clitoris to the left minor labium. After diagnostic biopsy, a preoperative lymphoscintigraphy with 99m-Tc nanocolloid was performed. Surgery consisted in a radical vulvectomy, radio-controlled lymphadenectomy and vulvar reconstruction by two bilateral subgluteus soft-tissue flaps, anastomosing the urethral and vaginal stumps. Five years follow-up was negative for neoplastic recurrence.

[Merkel cell carcinoma and sentinel lymph node dissection: nine cases report]

Merkel cell carcinoma (MCC) is an aggressive cutaneous-neuroendocrine neoplasia with poor prognosis and high propensity for locoregional and distant metastasis. Lack of knowledge about its biological behavior, pathogenesis, and prognostic factors, complicates the prospective evaluation. Sentinel node dissection, concomitant with radical excision of the lesion, has increased in the last few years. The suitability of this technique is linked to the MCC high tendency to spread "in primis" at locoregional nodes such as other malignancies such as cutaneous melanoma. Aim of the study is the prospective evaluation of the sentinel node dissection and of the adjuvant therapies in 9 patients MCC affected. All patients, underwent evaluation and staging of the neoplasia. Diagnosis was made by excisional biopsy and histological examination. Sentinel node dissection was performed in patients without clinical locoregional metastases (8 cases). Patients with sentinel node positive for metastasis underwent radical lymphadenectomy (3 cases). One patient affected by clinically locoregional metastases had, at once, radical lymphadenectomy. Radiotherapy and/or chemotherapy as adjuvant therapy were implemented (4 cases).

Vulvar primitive melanoma and sentinel lymph node: case report

The case of a 54-year-old woman who developed vulvar melanoma arising from a melanocytic lesion, extending from the clitoris to the left labium minor, without clinical involvement of the groin node station bilaterally is presented. The patient first underwent an incisional diagnostic biopsy that revealed a melanoma 4 mm in thickness; subsequently preoperative lymphoscintigraphy with 99m Tc Nanocoll was executed. Surgery consisted of a radio-controlled lymphadenectomy and radical vulvectomy. Two bilateral subgluteus soft-tissue flaps were made to reconstruct the surgical defect, anastomosing the urethral and vaginal stump. At 36 months follow-up the patient was negative for neoplastic recurrence.

[Merkel cell carcinoma]

Merkel cell carcinoma is a rare form of skin cancer of likely neuroendocrine origin wich affects mainly white population in sun-exposed areas. It is an aggressive tumor and survival is dependent on stage at the time of diagnosis. The staging evaluation include CT imaging and recently PET scan. Surgical excision with or without lymph node dissection, followed by postoperative radiotherapy in stage II disease, is the standard treatment of non metastatic disease. The role of adjuvant chemotherapy is still controversial. In patients with metastatic disease, chemotherapy regimens active in small cell lung cancer are generally used. The combination of cyclophosphamide, doxorubicin and vincristine (CAV) has an overall response rate of 75%, whereas the response rate of etoposide in combination with cisplatin or carboplatin is 60%. Experience with other therapeutic agents, such as tumor necrosis factor, interferon and octreotide is scanty. Recently, encouraging preliminary results with targeted agents have been reported. Our experience in 14 patients, four of whom treated with chemotherapy for advanced disease, is in agreement with literature

Basal cell carcinoma of the nose requiring amputation arising after irradiation for childhood hemangioma

A 49-year-old female, who had undergone irradiation at six years of age as a treatment for a cutaneous nasal hemangioma, developed later a devastating basal cell carcinoma requiring sub-amputation of the nose and subsequent reconstruction with a pre-expanded forehead flap. Basal cell carcinomas are now frequently reported as late sequelae of previous low-dose irradiations after 10-20 years, and patients should be aware of this possible evolution.

Reduction of behavioural disturbances in elderly dogs supplemented with a standardised Ginkgo leaf extract

In this open clinical trial conducted in 10 veterinary practices, Ginkgo leaf extract was administered as a dietary supplement to 42 elderly dogs (mean age 11.4 years) at a daily dose of 40 mg/ 10 kg body weight for 8 weeks. The "severity of the geriatric condition" in dogs with a history of geriatric behavioural disturbances (mean duration 12 months), was significantly reduced after 8 weeks of treatment (P = 0.0002). The positive effect was already apparent after 4 weeks. Thirty-six % of the dogs were completely free of clinical signs at study end. Overall efficacy of treatment as judged by the investigator was good or very good in 79% of the dogs. Five of six clinical sign scores (disorientation, sleep/activity changes, behavioural changes, general behaviour and general physical condition/vitality) also showed a significant decrease over the treatment period. In conclusion, these findings provide promising results that could increase the quality of life in the elderly dog and, as a consequence, that of the pet owner. The Ginkgo leaf extract appears to be an efficacious agent that provides a safe dietary supplement for the elderly dog with age-related behavioural disturbances.

Topical tea tree oil effective in canine localised pruritic dermatitis--a multi-centre randomised double-blind controlled clinical trial in the veterinary practice

Tea tree oil, a volatile oil, is well known for its broad antibacterial and antifungal activity. A standardised and stabilised 10% tea tree oil cream was tested against a commercial skin care cream (control cream) in the management of canine localised acute and chronic dermatitis. Fifty-seven dogs with clinical manifestations of mostly pruritic skin lesions or alterations, skin fold pyodermas and other forms of dermatitis, corroborated by predominantly positive fungal and bacterial skin isolates, were enrolled by seven practising veterinarians and randomly allocated to two study groups (28:29) and were treated twice daily with a blinded topical preparation. After 10 days of treatment, success rates of 71% for the tea tree oil cream and 41% for the control cream (over-all efficacy documented by the veterinary investigator) differed significantly (p = 0.04), favouring tea tree oil cream treatment. Accordingly on day 10, the tea tree oil cream caused significantly faster relief than the control cream (p = 0.04) for two common clinical dermatitis signs, pruritus (occurring in 84 % of dogs) and alopecia. Only one adverse event was reported in the tea tree oil group (suspected not to be causally related to the study drug) and none in the control cream group. The tested herbal cream appears to be a fast-acting safe alternative to conventional therapy for symptomatic treatment of canine localised dermatitis with pruritus.

Dietary support with Boswellia resin in canine inflammatory joint and spinal disease

An open multi-centre veterinary clinical trial, comparing conditions before and after treatment with a herbal dietary supplement consisting of a natural resin extract of Boswellia serrata, was conducted by 10 practicing veterinarians in Switzerland. This traditional plant-based supplement is known for its anti-rheumatic and anti-inflammatory properties. 29 dogs with manifestations of chronic joint and spinal disease were enrolled. Osteoarthritis and degenerative conditions were confirmed radiologically in 25 of 29 cases. The resin extract (BSB108, product of Bogar AG) was administered with the regular food at a dose of 400 mg/10 kg body weight once daily for 6 weeks. Already after two weeks of treatment, an overall efficacy of the dietary supplement was evident in 71% of 24 eligible dogs. A statistically significant reduction of severity and resolution of typical clinical signs in individual animals, such as intermittent lameness, local pain and stiff gait, were reported after 6 weeks. Effects of external factors that aggravate lameness, such as "lameness when moving" and "lameness after a long rest" diminished gradually. In 5 dogs, reversible brief episodes of diarrhea and flatulence occurred, but only once was a relationship to the study preparation suspected. Because quality and stability of the resin extract were ensured, these data suggest that a standardized preparation can be recommended as a herbal dietary supplement providing symptomatic support in canine osteoarthritic disease.

Echinacea powder: treatment for canine chronic and seasonal upper respiratory tract infections

An open multi-centered veterinary clinical trial, comparing conditions before and after treatment with a herbal preparation, containing the powdered root of Echinacea purpurea, was conducted by 6 practicing veterinarians in Switzerland. The plant-based immune stimulant was administered to 41 dogs with manifestations of chronic and seasonal upper respiratory tract infections, including pharyngitis/tonsillitis, bronchitis and kennel cough. Each animal was at an individual stage of the disease, with various symptoms and different severity scores, at start of treatment. There was no control group. Echinacea powder (1:3) was administered with the food at a dose of 1.0 g/10 kg body weight once daily for 8 weeks. Overall efficacy showed significant improvement for 92% of 39 dogs after 4 weeks of treatment and this was confirmed after 8 weeks. Significant reductions of severity and resolution of typical clinical symptoms, of clear nasal secretions, enlargement of lymph nodes, dry cough, dyspnea and dry lung sounds, were evident after 4 weeks. Only two adverse effects, not suspected to be attributable to the study drug, were recorded. Because quality and stability of the Echinacea powder were defined, using an analytical standard and purity tests, these data suggest, that the Echinacea preparation can be recommended as a well tolerated alternative treatment of canine upper respiratory tract infections.

Comparison of two fluorescence immunoassay methods for the detection of endocrine disrupting chemicals in water

We describe two fluorescence immunoassays capable of detecting endocrine disrupting compounds in waste water. The first fluorescence method is a heterogeneous assay using total internal reflection fluorescence (TIRF) detection. The second method is a homogeneous assay that utilizes energy transfer (ETIA). Both fluorescence immunoassays are compared with respect to detection principle and ability to quantify the model analytes estrone, estradiol, and ethinylestradiol in a complex matrix regarding recovery rates and limits of detection. Calibrations were performed for the three analytes using both fluorescence methods. Limits of detection between 0.01 and 0.85 microg/l are achieved. In addition, measurements in synthetic waste water spiked with the analytes were performed. Both immunoassays allow the detection in waste water with recovery rates in the range of 70-112%.

[Plantar fibromatosis: ultrasonography results]

INTRODUCTION

Plantar fibromatosis, or Ledderhose's disease, is a fibrous proliferation arising within the plantar fascia end exhibiting typical clinical nodular features. The lesion appears as a firm single thickening or a nodule, occasionally painful, localized to the medial portion of the sole of the foot. This unusual condition has not been extensively studied with US and very little has been written about it.

MATERIAL AND METHODS

In 1998-99, six patients with plantar fibromatosis were submitted to US with 13 MHz linear array and 20 MHz mechanical annular array probes. All patients were examined in prone recumbency with the probe positioned on the sole of the foot. Only some of them were subsequently submitted to surgery.

RESULTS

Plantar fibromatosis exhibited an almost pathognomonic pattern and US proved to be a quick, noninvasive and cost-effective technique to confirm clinical diagnosis. The nodule is typically single and isoechoic, with maximum diameter of about 1 cm, inhomogeneous internal structure and few thin hyperechoic septa. The nodular fibrous proliferation adheres with the major axis along the plantar fascia; it exhibits clear-cut margins and US beam transmission is good. No calcifications or fluid collections are seen within the nodule. Color and power Doppler show no flow inside.

CONCLUSIONS

US is an adequate tool for the study of plantar fibromatosis.
