Isolated Roux-en-Y versus single loop pancreaticojejunal reconstruction after pancreaticoduodenectomy - a systematic review and meta-analysis of randomised controlled trials.

BACKGROUND: Pancreaticoduodenectomy is a complex intra-abdominal operation used for the treatment of benign and malignant disease of the pancreatic head or periampullary region. Despite developments in surgical techniques, pancreaticoduodenectomy is still associated with high rate of postoperative complications. We performed this systematic review and meta-analysis to compare the surgical outcomes of isolated Roux-en-Y pancreaticojejunostomy (IRYPJ), and conventional pancreaticojejunostomy(CPJ). METHODS: We performed a systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. We searched the following electronic databases - PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and Clinical-Trials.gov. Published trials comparing the efficacy and safety of IRYPJ and CPJ after pancreaticoduodenectomy were evaluated. The search terms were "pancreaticoduodenectomy," "Whipple," "pylorus-preserving pancreaticoduodenectomy," "pancreaticojejunostomy," "Roux-en-Y," and "isolated Roux loop pancreaticojejunostomy." Only randomised controlled trials comparing outcome of IRYPJ and CPJ after pancreaticoduodenectomy were included. The analysed outcome measures were postoperative pancreatic fistula (POPF), clinically relevant POPF (CR-POPF), bile leak and delayed gastric emptying (DGE). RESULTS: The initial search yielded 342 results but only four randomised control trials fulfilled the inclusion criteria and were included for data synthesis and meta-analysis. Meta-analysis of POPF revealed that IRYPJ is associated with less POPF compared to CPJ but the difference was not statistically significant (risk ratio = 0.58, p = 0.56). A similar finding was also observed with CR-POPF (risk ratio = 0.17, p = 0.87) and DGE (risk ratio = 0.74, p = 0.46). CONCLUSION: Isolated Roux-en-Y pancreaticojejunostomy is not associated with a superior outcome when compared to CPJ.

Delayed Presentation of Posttraumatic Diaphragmatic Hernia Masquerading as Recurrent Acute Asthmatic Attack.

Diaphragmatic hernia following blunt abdominal injury is extremely rare and often diagnosed late. Missed diagnosis is also common with this condition. We herein present a delayed presentation of diaphragmatic hernia following blunt abdominal injury that was initially misdiagnosed as recurrent acute asthmatic attack due to repeated presentation with episodic difficulty in breathing.

Can coverage of schistosomiasis and soil transmitted helminthiasis control programmes targeting school-aged children be improved? New approaches.

Control programmes generally use a school-based strategy of mass drug administration to reduce morbidity of schistosomiasis and soil-transmitted helminthiasis (STH) in school-aged populations. The success of school-based programmes depends on treatment coverage. The community-directed treatment (ComDT) approach has been implemented in the control of onchocerciasis and lymphatic filariasis in Africa and improves treatment coverage. This study compared the treatment coverage between the ComDT approach and the school-based treatment approach, where non-enrolled school-aged children were invited for treatment, in the control of schistosomiasis and STH among enrolled and non-enrolled school-aged children. Coverage during the first treatment round among enrolled children was similar for the two approaches (ComDT: 80.3% versus school: 82.1%, P=0.072). However, for the non-enrolled children the ComDT approach achieved a significantly higher coverage than the school-based approach (80.0 versus 59.2%, P<0.001). Similar treatment coverage levels were attained at the second treatment round. Again, equal levels of treatment coverage were found between the two approaches for the enrolled school-aged children, while the ComDT approach achieved a significantly higher coverage in the non-enrolled children. The results of this study showed that the ComDT approach can obtain significantly higher treatment coverage among the non-enrolled school-aged children compared to the school-based treatment approach for the control of schistosomiasis and STH.

Community perceptions on the community-directed treatment and school-based approaches for the control of schistosomiasis and soil-transmitted helminthiasis among school-age children in Lushoto District, Tanzania.

The success of the Community-Directed Treatment (ComDT) approach in the control of onchocerciasis and filariasis has caught the attention of other disease control programmes. In this study the ComDT approach was implemented and compared with the school-based approach for control of schistosomiasis and soil-transmitted helminthiasis among school-age children in Lushoto District, Tanzania. This was a qualitative study, consisting of in-depth interviews with village leaders, community drug distributors (CDDs) and schoolteachers, as well as focus group discussions with separate groups of mothers and fathers to assess the perceptions and experiences of the villagers on the implementation of the two approaches. It was found that the villagers accepted the ComDT approach and took the responsibility of selecting the CDDs, organizing and implementing their own method of distributing drugs to the school-age children in their villages. The ComDT approach was well received and was successfully implemented in the villages. Although the villagers pointed out the limitation in reaching the non-enrolled children in the school-based approach, they also expressed satisfaction with this approach. This study suggests that the ComDT approach is well accepted and can be implemented effectively to ensure better coverage of especially non-enrolled school-age children.

Giant and complicated subcutaneous lipoma of the neck.

BACKGROUND: Although lipomas around the head and neck region are not uncommon, giant lipomas around the neck are rare. OBJECTIVE: To report the case of a long standing giant lipoma of the neck which was managed easily by simple surgical excision. CASE REPORT: A case of giant subcutaneous lipoma of the neck is reported in a 70 year old woman who presented with dragging sensation and bleeding from the site of pressure ulceration as the major complaint. The patient was evaluated and definitive diagnosis was arrived at using Fine Needle Aspiration Cytology (FNAC). She had a successful Surgical excision and was subsequently discharged but never came back for follow up. CONCLUSION: Lipoma should always be considered in the differential diagnosis of pedunculated lesions around the neck.

Use of protective eyewear among surgeons in a tertiary hospital in northern Nigeria.

The study was a prospective study during which a hand-held lens was used to examine the goggles of all surgeons who used them during surgery at Aminu Kano Teaching Hospital, Kano, Nigeria. Only 169 (54.8%) of the 308 surgeons used eye protection during surgery. There was at least a bloodstain on 70 (41.4%) of the goggles. There is need to enforce universal precautions during surgery to protect the eyes of surgeons from blood drops of the patient being operated.

Radical Cystectomy for Locally Advanced Carcinoma of the Bladder in Kano; Nigeria

Objective: Bladder cancer is the second most common genito-urinary malignancy worldwide. The objective of this study was to assess the benefit of radical cystectomy on locally advanced bladder carcinoma in terms of improved quality of life and survival in our environment. Patients and Methods : The records of 58 patients with bladder carcinoma managed at Aminu Kano Teaching Hospital over a 5-year period (May 2000 to April 2005) were reviewed and analysed. Excluded were 28 patients with distant metastatic disease discovered during clinical investigation. Results: Thirty patients (25 males and 5 females) with a mean age of 50.5 years and variable symptoms underwent radical cystectomy for locally advanced carcinoma of the bladder. Urinary drainage was achieved by orthotopic ileal neobladder in 15 patients (50); continent cutaneous reservoir in 11 patients (36.7) and non-continent drainage in 4 patients (13.3). A 40survival was achieved at 6-60 months. Conclusion : Radical cystectomy is a worthwhile procedure in locally advanced carcinoma of the bladder and cure may be achieved in selected patients

Glomus tumour--the report of a case in an adult Nigerian.

BACKGROUND: Glomus tumour, a relatively common lesion in Caucasians is reported to be rare in blacks. METHOD: A case of glomus tumour is reported in an adult male Nigerian to highlight its distinctive clinical presentation and the literature reviewed. RESULT: A 60-year old man presented with a painful skin nodule on the ventral surface of his right forearm. The pain was far in excess of the size of the lesion. There was however no relief from previous medications. Following complete excision of the lesion, pain relief was dramatic. Histopathological examination of the lesion showed sheets of round to polyhedral glomus cells and elongated endothelium lined vascular channels diagnostic of glomus tumour. CONCLUSION: Severe pain is a very important feature of glomus tumour of the skin. This is relieved by complete excision of the lesion.

Typhoid enteric perforation in north western Nigeria.

BACKGROUND: Typhoid perforation is the most important surgical complication of typhoid enteritis and is associated with high morbidity and mortality. AIMS AND OBJECTIVES: To determine the pattern and outcome of management of typhoid perforation in Aminu Kano University Teaching Hospital, Kano. METHOD: A retrospective Analysis of patients treated for typhoid perforation over a 6-year period. RESULTS: There were 47 patients: 35 males and 12 females, ratio 2.9 to 1. The patients were aged 4 years to 58 years (mean 18.9 years). Typhoid perforation occurred all the year round with a peak prevalence in September; Six (12.8%) patients perforated in the first week, 29 (61.7%) second week, and 12 (25.5%) third week, of illness. Single perforation was found in 91.5% of cases, and two to three perforations in 8.5%. Surgical treatment was by simple closure in 72.3%, wedge resection in 8.5%, ileal resection in 17.1% and right hemi-colectomy in 2.1%. Of the 41 survivors (87.2%), wound infection was the most common postoperative complication in 44.7% of cases. The mortality rate was 12.8% mostly due to overwhelming sepsis. CONCLUSION: Typhoid perforation requiring surgical intervention is still endemic in our subregion, and emphasis should be on preventive measures such as safe drinking water and appropriate sewage disposal, and typhoid vaccination.

Childhood intestinal obstruction in Northwestern Nigeria.

BACKGROUND: Intestinal obstruction is a common cause of childhood surgical emergency in the tropics. The aim of this paper was to assess the pattern and the outcome of mangement of intestinal obstruction in Nigerian children. STUDY DESIGN: The clinical reccords of all the cases of childhood intestinal obstructions managed at a teaching hospital in northwestern Nigeria between 1999 and 2003 were retrospectively reviewed. RESULTS: There were 54 children, 44(81.5 %) were boys and 10 (8.5 %) were girls (m:f=4.4:1). Fifteen (27.8%) and 22 (46.2%) were neonates and infants, respectively. The causes of the intestinal obstruction were intussusception 16(29.6 %), Hirschprung's disease 14(25.9%), anorectal anomaly 12 (22.2%), external hernias 6(11.1%), atresia 5(9.3%) and congenital bands 1(1.9 %). The clinical features were consistent with those reported from other parts of the world, except that many patients with intussusception presented late with gangrenous intestines. The overall mortality was 6(11.1 %); the mortality in the neonates was 5(33.3 %). CONCLUSION: Apart from the obvious absence of worm infestation, the aetiological pattern and the clinical presentation of childhood intestinal obstruction in this study agrees with those reported from other parts of the country. Their management is associated with high mortality in our environment, especially when there are associated anomalies or the presentation is late.

Malaria diagnosis and treatment administered by teachers in primary schools in Tanzania.

A school health programme in Mwera Division, Pangani District included treatment of malaria attacks occurring in children during school time. A combination of symptoms (headache, muscle/joint pains, feeling feverish) and oral temperature > or = 37.5 degrees C was used for the diagnosis of malaria. Chloroquine (25 mg/kg given over 3 days) was used for treatment. Malariometric surveys on children aged 7-15 years (mean 10 years) were conducted once a year (1995-1997). Plasmodium falciparum accounted for 100% of infections and the parasite prevalence varied between 32.7 and 35.3% from 1995 to 1997. The number of malaria cases (cases/1000 registered school children) diagnosed and treated by school teachers was 159 (67) in 1995, 324 (124) in 1996, 348 (128) in 1997 and 339 (108) in 1998. Children in grades 1-4 (age 7-13) accounted for 64.6% of cases. Symptoms and oral temperature were recorded for 1258 children. Of those, 992 (78.9%) complained of fever and at least one other symptom when presenting to teachers, 98 (7.8%) had fever as their only complaint and 168 (13.5%) presented without a perception of fever, but with other symptoms. Of these children, 36 (21.4%) had a temperature > or =37.5 degrees C. The sensitivity of "feeling feverish" was 96.5% with a specificity of 54.5%. The positive predictive value of feeling feverish was 89.9% and the negative predictive value 78.6%. Blood slides were prepared from 55.3 and 37.2% of children diagnosed by teachers during 1995 and 1996, respectively, and 71.4% were found positive. Among children who fulfilled the algorithm criteria 75.0% had a positive blood slide. With little training and regular supervision it was feasible for school teachers to make a presumptive diagnosis of malaria. We conclude that teachers can play a major role in school health programmes and are willing to be involved in health matters as long as they are supported by health and educational authorities.

The impact of a school health programme on the prevalence and morbidity of urinary schistosomiasis in Mwera Division, Pangani District, Tanzania.

The prevalence of urinary schistosomiasis among schoolchildren in Pangani District (Tanzania) was assessed rapidly by a questionnaire approach. Based on the results, a strategy of selective treatment with praziquantel was adopted. Eleven primary schools in Mwera Division, Pangani District, with about 2500 schoolchildren were included in a control programme for urinary schistosomiasis. Macro- and microscopic haematuria diagnosed visually and with urine reagent strips was used as an indirect indicator of Schistosoma haematobium infection. Intensity of infection among children was monitored in class 5 (median age 14 years, range 11-17) by urine filtration techniques. Treatment was administered as 40 mg/kg praziquantel in a single dose at the beginning of the school year. The programme was implemented by schoolteachers and coordinated by the District Health Management Team in collaboration with the District Education Office. Teachers were responsible for carrying out all programme activities. Community participation was through collaboration with Teachers-Parents Associations and Village Health Committees. Coverage at yearly (1995-99) examination varied from 67.7% to 80.3%. Prevalence of haematuria decreased from 51.2% (range 22.2-89.5%) at baseline to 23.4% (range 5.8-56.7%) in 1999, a reduction of 54.3%. Macrohaematuria was 21.2% at baseline and 7.2% in 1999, a reduction of 66.0%. Prevalence of infection in class 5 was reduced by 71.4% and geometric mean intensity of positives reduced from 71 eggs/10 mL (95% confidence interval [CI] 52.5-97.7) to 28 eggs/10 mL (95% CI 25.7-55.0), a reduction of 60.6%. Teachers were highly committed, and secured community participation and a smooth implementation of the programme. The community accepted the introduction of a cost-recovery system, whereby parents pay for the treatment of children with episodes of visible haematuria during the school year. Communities also participated in the improvement of sanitary installations at the schools.
