Describe the distribution that the patients who came to the Physical Medicine Service of Hospital Eugenio Espejo since January - December 2006. Estudio descriptivo en el que se aplicó el sistema de evaluación de discapacidad establecido por el Consejo Nacional de Discapacidades (CONADIS) a todos los pacientes que acudieron durante este período, y se registró en una base de datos que contenían variables de estudio. El 59 por ciento fueron de sexo masculino y 41 por ciento del sexo femenino, mayores de 20 años, la discapacidad física es mayoritaria en el sexo masculino y la discapacidad psíquica representa una minoría en los dos sexos, encontrando que la causa principal de discapacidad física es la amputación de miembros inferiores. El grado de discapacidad moderado fue el más frecuente y más en hombres que en mujeres, siendo el 88 por ciento de personas discapacitadas procedentes de Pichincha. Por los resultados obtenidos en nuestro estudio concluimos que es alta la frecuencia de discapacidad moderada por lo cual recomendamos realizar labores de prevención, diagnóstico y tratamiento e incorporar a la persona discapacitada en medida de sus limitaciones a la sociedad.

Correlation between the uptake of sodium fluorescein in the tissue and xenon-133 clearance and laser Doppler fluxmetry in measuring changes in skin circulation.

We have measured the plantar forefoot skin circulation by the uptake of sodium fluorescein (fluorescein flowmetry), 133Xe clearance and laser Doppler fluxmetry in 24 healthy subjects and correlated measurements under basal conditions and after provocation by alcohol intake and application of external heat. To assess the change in skin circulation between the initial measurement at rest and the second measurement after provocation, the coefficient of correlation (r) of the fluorescein flowmetry to the fast slope of the 133Xe elimination curve was 0.46 (p < 0.05), to the slow slope of the 133Xe elimination curve 0.66 (p < 0.001) and to laser Doppler fluxmetry 0.86 (p < 0.001). The coefficient of correlation (r) of the fluorescence appearance time to fluorescein flowmetry was 0.65 (p < 0.001), to the fast slope of the 133Xe elimination curve 0.14 (p = 0.42), to the slow slope of the 133Xe elimination curve 0.47 (p < 0.05) and to laser Doppler fluxmetry 0.63 (p < 0.001). The uptake of sodium fluorescein as measured by fluorescein fluxmetry correlates well with both 133Xe clearance and laser Doppler fluxmetry in assessing a change in skin circulation in healthy humans. The fluorescence appearance time also correlates to the slow slope of the 133Xe elimination curve and to laser Doppler fluxmetry though to a lesser extent.

Influence of the site of skin incision on the circulation in the nipple-areola complex after subcutaneous mastectomy in breast cancer.

Necrosis of the skin resulting from impaired perfusion is one possible complication of subcutaneous mastectomy. The aim of this study was to evaluate the influence of two differently sited skin incisions on the circulation in the nipple-areola complex and in the surrounding skin. Sixty-nine patients with invasive breast cancer underwent subcutaneous mastectomy and immediate reconstruction with a subcutaneously placed prosthesis. In 26 of them a "lazy-S"-shaped horizontal lateral incision was made, and in 43 patients a transverse incision 1.5 cm above and parallel to the submammary fold. The skin circulation was measured by two methods, laser Doppler flowmetry (LDF) and fluorescein flowmetry, two or three days postoperatively. The skin circulation in the nipple-areola complex and in the skin 2 cm above the complex was the same irrespective of which of the two incisions was used, both by LDF and fluorescein flowmetry, but 2 cm below the complex fluorescein flowmetry showed 36% lower circulation in the submammary incision group than in the group with a lazy-S incision (p < 0.01), in contrast to LDF, which did not show any differences between the incisions. The circulation measured by LDF was higher in all three areas both with the lazy-S incision and with the submammary incision than in the opposite untreated breast. With fluorescein flowmetry there was a corresponding increase by 36% (p < 0.01) below the complex in the lazy-S incision group. There was no skin necrosis. In conclusion, the site of the skin incision used in this study did not influence the circulation in the nipple-areola complex or in the skin 2 cm above the complex as measured by LDF and fluorescein flowmetry. However, there was a reduction of the superficial circulation as measured by fluorescein flowmetry 2 cm below the complex in the submammary incision group. The increased circulation in the breast operated on was probably the result of traumatic hyperaemia.

Effect of exposure to heat and intake of ethanol on the skin circulation and temperature in ischaemic limbs.

The question of whether alcohol intake increases skin circulation is controversial. The study described here was undertaken to examine the effect on skin circulation and skin temperature in ischaemic limbs of exposure to external heat, and of alcohol intake together with such exposure. Fourteen patients with occlusive arterial disease, mean age of 65 years (range 47-80), underwent measurements of blood flow by laser Doppler flowmetry (LDF) and of skin temperature 1-2 days before and 8-10 days after vascular reconstruction. LDF and skin temperature were measured in the plantar region of the mid-forefoot with the subject supine. After 30 min of exposure to external heat, the measurements were repeated. Each subject then drank 15 ml of 50% alcohol and after a further 30 min of heat exposure the same measurements were performed again. Similarly, fourteen healthy subjects, mean age 33 years (range 21-43), were studied. In the patients there was no increase in skin blood flow or skin temperature after heat exposure alone or after combined heat exposure and alcohol intake, either before or after vascular reconstruction. In the healthy subjects LDF showed a 126% increase (P < 0.01) in skin blood flow after 30 min of exposure to external heat and a further increase by 81% after alcohol intake and an additional 30 min of heat exposure (P < 0.01). The corresponding increases in skin temperature were 3.0 degrees C (P < 0.05) and 2.9 degrees C (P < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Changes in skin blood flow in ischaemic limbs after vascular reconstruction measured by fluorescein flowmetry and laser Doppler flowmetry.

It is not known to what extent the skin blood flow increases after vascular reconstruction in ischaemic limbs. Thus, a study was undertaken to measure skin blood flow, using the two techniques laser Doppler flowmetry and fluorescein flowmetry, before and after vascular reconstruction. The skin temperature was measured also. The plantar circulation was assessed in 14 patients (9 non-diabetics and 5 diabetics; mean age 65 years; range 47-80), with the patient in the supine position, 1-2 days before and 8-10 days after surgery. After vascular reconstruction the skin blood flow increased by 240% (P < 0.01) when measured by fluorescein flowmetry and by 148% (P < 0.01) when measured by laser Doppler flowmetry, and the skin temperature rose by 3.2 degrees C (P < 0.01). In the contralateral non-operated limb there was no significant change in skin blood flow as measured by the two methods. The results imply that after vascular reconstruction in ischaemic limbs the skin blood flow increases both in the superficial layer as determined by fluorescein flowmetry (which measures the blood flow down to 0.6 mm) and in deeper layers as determined by laser Doppler flowmetry (which measures flux down to 6 mm).

The effect of weight-bearing pressure on the plantar circulation in diabetes mellitus.

Patients with diabetic neuropathy are prone to ulceration on the sole of the foot, especially in areas with high weight-bearing pressure. The relationship between weight-bearing pressure and nutritive skin circulation in the plantar region was studied. Gait analysis was performed with the EMED Gait Analysis System and the skin circulation was measured by fluorescein flowmetry in ten neuropathic diabetic patients and in eight healthy controls. The critical plantar foot pressure above which nutritional blood flow in the skin was arrested was 3 N cm-2 or more in both diabetic and control subjects. Below 3 N cm-2 the blood flow was independent of weight-bearing pressure both in diabetic and control subjects (correlation coefficient r = -0.01 and -0.19, respectively). Thus, our results indicate that the nutritional blood flow in the plantar region is not decreased in patients with diabetic neuropathy.

The circulation in the nipple-areola complex following subcutaneous mastectomy in breast cancer.

To evaluate the decrease in circulation in the nipple-areola complex after subcutaneous mastectomy and immediate implantation of a submuscular prosthesis, the blood flow was studied by both fluorescein flowmetry and laser Doppler flowmetry in 24 patients with invasive breast cancer. In 14 patients a lazy-S-shaped horizontal lateral incision was used, and 10 underwent a subcutaneous reduction mammaplasty. After subcutaneous mastectomy with a lazy-S incision there was no significant decrease in blood flow in the nipple-areola complex compared with that in the untreated contralateral breast. In the breasts in which reduction mammaplasty had been done, the blood flow was reduced by 74% as measured by fluorescein (p less than 0.01), and 70% by laser Doppler flowmetry (p less than 0.05), compared with the contralateral breast. Five patients had partial or complete epidermal, and one patient had total dermal, necrosis of the complex, but there was no deep necrosis. No fluorescence was seen within the areas in which necrosis later developed in any of these six cases. The laser Doppler signal in the corresponding areas, however, was not reduced. The results show that the circulation in the nipple-areola complex is reduced more after subcutaneous reduction mammaplasty than after subcutaneous mastectomy with a lazy-S incision.

Skin circulation in the nipple after reduction mammaplasty with a bipedicle vertical dermal flap.

Necrosis of the nipple after a reduction mammaplasty with transposition of the nipple is a serious complication. A study was undertaken to measure the skin circulation in the nipple before, during and after this operation. In 16 patients undergoing reduction mammaplasty according to the method of McKissock, the skin circulation was measured in both breasts by laser Doppler flowmetry (LDF) and fluorescein flowmetry (FF). LDF showed that the skin circulation increased after de-epithelialization to 245.7 +/- 39.3% of the preoperative blood flow (100%) (mean +/- SEM, p less than 0.01). When 40 ml of 0.25% adrenaline was injected into the incision lines, the corresponding increase in blood flow was 153.4 +/- 15.6% (p less than 0.01). After the medical and lateral glandular resections the blood flow in the nipple of the vertical dermal pedicle was 125.6 +/- 21.2% of the preoperative blood flow and when adrenaline was given the corresponding value was 79.3 +/- 6.5%. After the skin had been sutured, the blood flow was 128.4 +/- 25.9% of the preoperative value and in the breast in which adrenaline was injected it was 177 +/- 96.9%. One to four days postoperatively the blood flow was 123.1 +/- 19.9% of the preoperative value and in the breast that received adrenaline 130 +/- 24%. At FF homogeneous fluorescence was observed in the nipple postoperatively in all patients but one; in this patient avascular necrosis later developed. Our results thus show that the circulation in the nipple after reduction mammaplasty by the McKissock method is adequate.

Correlation between fluorescein flowmetry and laser Doppler flowmetry. A study in the intestine (ileoanal pouch) in man.

A study was undertaken to compare two new methods of capillary blood flow measurement, namely fluorescein flowmetry (FF) and laser Doppler flowmetry (LDF). The blood flow was measured in a pelvic pouch during its construction and in the completed ileoanal anastomosis in 12 patients. There was a high correlation between the two methods (correlation coefficient, 0.78) (p less than 0.01) when the blood flow was measured in the pelvic pouch. The correlation coefficient between the two methods for the difference between the blood flow in the pelvic pouch at the site of the planned anastomosis when the pouch resided in the abdomen and that in the completed ileoanal anastomosis was r = 0.99 (n = 12, p less than 0.001); the reduction amounted to 25% as measured by FF and 27% as measured by LDF (n = 12, p less than 0.01). All ileoanal anastomoses healed perfectly, the lowest FF and LDF values being 0.004 density units/sec and 0.3 V, respectively. The results indicate that either method can be considered for measuring capillary blood flow.

Endoscopic papillotomy in the management of choledocholithiasis.

Endoscopic papillotomy was attempted in 72 patients with common bile duct stones, 47 of whom previously had been cholecystectomized and 25 with their gallbladder still present. Papillotomy was successful in 69 patients (96%) and the duct was cleared of stones in 63 (88%). Nine patients thus needed elective surgery. There was no mortality following papillotomy and no grave complication occurred. On the follow-up, from 5 months to 10 years (mean 4 years), only one of the 63 patients with successful papillotomy has required operation. Endoscopic papillotomy is effective for treating many patients with choledocholithiasis, both in those following cholecystectomy and in those with gallbladders in situ.
