The related factors influencing development of language understanding and expression of early-children / 中华预防医学杂志

<p><b>OBJECTIVE</b>To assess the level of language understanding and expression of healthy children aged from 8 to 16 months in urban Beijing and to investigate the children's physical and psychological development conditions and social and economic status of children's family as to identifying the related factors to children's language development and providing a basis for instructing parents child-rearing and promoting early children language development.</p><p><b>METHODS</b>A quantitative Cross-sectional Study was made. The parents or care givers of 636 healthy young children, randomly stratified and selected in two districts in Beijing were interviewed. T-test was used to compare the scores of language understanding and expression between boys and girls in the same age. Single and multiple factors analysis were used so as to find out the related factors.</p><p><b>RESULTS</b>For boys, the average scores of language were respectively 115.0 for 8 months, 243.0 for 12 months and 410.6 for 16 months; for girls the average scores were respectively 109.9 for 8 months, 286.4 for 12 months and 456.2 for 16 months. The average score of language understanding of boys was higher than that of girls only in the 11 month group. The average scores of language expression of girls were higher than those of boys in 11, 12, 14, 15 month groups. Multiple factors analysis showed that parent-child book reading, parent-child tape listening, higher education level of grandmothers, children' extroversion personality, child being able to speak one word and children's age were positively related to the children' language score.</p><p><b>CONCLUSION</b>Providing rich language environment should be helpful to early children's language development.</p>

Cancer of the colon and rectum in a Jamaican population: diagnostic implications of the changing frequency and subsite distribution

The aim of this study was to examine the clinical and pathological characteristics of colorectal cancer in Jamaica, to determine whether there was a change in the anatomic distribution and clinical presentation and to discuss the options for diagnosis and management. A comprehensive retrospective review of patients newly diagnosed with colorectal carcinoma was conducted at The University Hospital of the West Indies by reviewing both patient records and pathological data. These data were compared with previous reports of patients with colorectal cancer seen in Jamaica. One hundred and forty-seven patients were studied There were 85 females and 62 males with a female to male ratio of 1.37:1. The median age was 65.5 years (range 19 to 94 years). The predominant symptoms were abdominal pain in 91 patients, change in bowel habit in 77 patients and rectal bleeding in 74 patients. Sixty patients presented with weight loss and 28 with a rectal mass. The most common tumours were right-sided colonic cancers in 42 patients (28.5) followed by sigmoid colon in 30 (20.4) rectum in 34 (23.1) and left and transverse colon accounting for 16 and 10 cases respectively. Most of the tumours were well or moderately differentiated adenocarcinomas. Only eight patients presented with Dukes' A disease, 50 with Dukes'B, 53 with Dukes'C disease and 34 with advanced disease. The findings showed that sigmoid and rectal tumours accounted for 43.5 of cancers. The colon/rectum ratio in this series was 3.3:1 indicating a significant proximal shift of colorectal cancers in this population in keeping with recent reports. The results of the current study suggest that the sub-site location of colorectal cancers seen is similar to that reported in high incidence countries such as the United States of America and parts of Europe but differs from the African continent which has a high proportion of rectal tumours. This right-sided preponderance also differs from previous studies in Jamaica, which report a higher incidence of rectal lesions The detection of early colorectal carcinoma will require screening at a stage when the disease is asymptomatic in order to improve the chance for cure. The data presented here imply that screening programmes should allow evaluation of the entire colon rather than the distal 25 cm

Thymic surgery in Jamaica 1992-2000

The treatment for thymic tumours and/or myaesthenia gravis (MG) includes thymectomy. Controversy exists as to the optimal timing and operative approach to thymectomy. At the University Hospital of the West Indies, Kingston, Jamaica, the results of thymic surgery during the period 1992 to 2000 were studied retrospectively. There were 26 patients operated on, 17 females and nine males. Twenty-three underwent thymectomy to treat MG, and three to remove a thymoma. The average age for females was 30.7 years, and 25.1 years for males. Average duration of symptoms prior to surgery was 16 months (all patients), and the interval between diagnosis and referral averaged 2.6 months. All patients underwent thymectomy via median sternotomy with a cervical extension of the incision if required. A policy of phrenic nerve preservation, even if residual tumour was left behind, was followed. Patients with thymomas were given post-operative radiotherapy. Chemotherapy was not given to any patient. The medium and long term results of thymic surgery in a developing country are presented. The results are within international norms, although the small patient population makes statistical analysis difficult. There appears to be no need to change current practice, despite the reported efficacy of less invasive approaches to thymic surgery

A clinico-pathological study of Cushing's syndrome at the University Hospital of the West Indies and a review of the literature

Cushing's syndrome is an uncommon but important disease. Twenty-one confirmed cases of spontaneous Cushing's syndrome were documented at the University Hospital of the West Indies over a 21-year period. They were predominantly young females (F:M ratio of 17:4; mean age 25 years and 3 months). The commonest presenting symptoms were amenorrhoea (41) and obesity (19). Common clinical features were cushingnoid features (95), hypertension (76) and hirsutism (82). Twenty-nine per cent had frank hyperglycaemia. Cushing's syndrome was due to Cushing's disease in 10 cases, adrenal adenoma in 3 and adrenal carcinoma in 2 cases. In 4 cases with presumed adrenal hyperplasia, the histology was either unavailable or was not consistent with the diagnosis. Two cases appear now to have had the ectopic ACTH Syndrome. Adrenalectomy was the commonest treatment offered. There were no intra-operative or post-operative deaths but recurrence was common after subtotal adrenalectomy in Cushing's disease. Twenty-seven per cent of the patients developed Nelson's syndrome, which was fatal in 50. Long-term hormone replacement therapy was unnecessary after surgery for adrenal adenomas. Treatment of Cushing's syndrome was well tolerated by the patients.

Treatment of low rectal carcinoma by transanal electrocoagulation

This study reports the first 13 cases of biopsy-proven low rectal carcinoma treated by transanal electrocoagulation using a locally manufactured instrument. At the University Hospital of the West Indies, over a 16-year period, 9 patients were treated for cure, six of whom have no clinical evidence of recurrence for one to 12 years. Four cases who were offered this procedure for palliation defaulted after a single treatment. Transanal electrocoagulation provides an additional option for treating patients with small, mobile low rectal cancers, following careful screening for evidence of nodal or distant spread. The procedure can also be used in the local control of disease in patients with distant spread or in whom a major operation is not feasible.

Trauma aetiology and cost in the Accident and Emergency Unit of the University Hospital of the West Indies

Trauma accounted for 37of 22,311 patients seen in the Accident and Emergency Unit (A&E Unit) at the University Hospital of the West Indies (UHWI) during 1996. Thirty-nine per cent of injuries were intentional and 18were due to motor vehicle accidents. Knives, machetes and rocks accounted for 75of the injuries compared with 5for gunshot wounds. Passengers were injured in about 40of motor vehicle accidents and pedestrians in 19. The admission rate was 16and the orthopaedic clinic received 75of the patients referred to specialist clinics. Victims of motor vehicle accidents made up a greater proportion of admissions (24) than those of intentional violence (13). The average cost of caring for each patient in the A&E unit was US$70 resulting in an annual cost of US$578,000.

Appendicectomy at the University Hospital of the West Indies (1984-1988): A retrospective review

The pathological records of appendicectomy specimens from patients with suspected acute appendicitis at the University Hospital of the West Indies during the 5-year period 1984-1988 were studied. The numbers of cases, their ages, sex and seasonal incidence were similar to those of other studies. The over-all false positive diagnosis rate was 25%(16%in males, 38%in females). The main diagnostic difficulty was in young females in whom surgery for suspected appendicitis often proved unnecessary.

Spontaneous rupture of the normal colon

A case of spontaneous rupture of the colon in a previously asymptomatic patient is herein reported. At laparotomy, apart from the tear in the sigmoid colon, no other pathological problem was present. An awareness of the existence of this condition will lead to early diagnosis and management with improved morbidity and mortality.

Ruptured rectal prolapse

Rectal prolapse is not a common surgical disorder. The complication reported here, of evisceration of small bowel through a prolapsed rectum, is extremely rare and is the first case reported in the West Indies. Someof the features of rectal prolapse are described, and the surgical management ofthis particular complication is discussed

Fine needle aspiration biopsy in the diagnosis of breast cancer

A prospective study of 176 Fine Needle Aspiration Biopsies (FNAB) in 172 patients was carried out to assess the accuracy of FNAB in diagnosing breast cancer at the University Hospital of the West Indies. The results showed 99 per cent and 97 per cent accuracy and sensitivity rates, respectively. There were no false positives and a one per cent false positives and a one per cent false negative rate. FNAB provides a rapid, safe and cheap method of accurately diagnosing breast cancer

Parasitism and nutritional status of poor suburban jamaican toddlers

A survey was conducted on 145 toddlers, 6-36 months of age, in a suburb in Kingston, Jamica. The aim of the study was to measure the prevalence of and association between parasitism and nutritional status. Forty-two per cent were malnourished ( <80% of standard weight for age), most commonly (76%) in the 12-17 month age group. Thirty-four per cent hada one or more parasites, particularly Trichuris trichuria (21%) or Ascaris lumbricoides (19%). The peak prevalence of parasitism was among the 30-36 month old children (63%). Nutritional status did not differ between children with and without parasites. Most of them had light of infection. Therefore, in this sample, there was no association between parasitism and nutritional status

Incarcerated obturador hernia

Incarcerated obturator hernia is rara, only approcimately 550 cases appearing in the literature since the first case was reported in 1924. The three cases treated at the university Hospital of the west Indies are presented. they demonstrate many of the clinical features of the condition. Most cases occur in elderly womwn and they almost always present with symptoms and signs of small bowel obstruction. Pressure on the abturator nerve by the hernial sac in the obturator canal results in a positive Howship-Romberg sign in about 50% of patients. If the diagnosis is suspected pre-operatively, confirmation may be obrained by computerized tomography. this, hower, seems unnecessary as prompt exploration is advisable due to the high incidence of gangrene of the vowel. At surgery at reduction frequently result in damage to the small bowel, and resection is often necessary due to injury or gangrene. Closure of the entrance to the canal with interrupted non-absorbable sutures is adequate, and prosthetic material is necessary only for very large defects. The high mortality rate reported is probably due to the age and poor general condition of affected patients

Benign biliary strictures

Benign biliary strictures are rare. Their management represents a challenge to the practising surgeon. Six cases seen at the University Hospital of the West Indies are reviewed. Early recognition and management by an experienced surgeon will improve prognosis
