Yacon Extract Attenuated Kidney Fibrosis in 5/6-subtotal Nephrectomy Mouse Model by Upregulating HGF and BMP-7 mRNA Expression

@#Introduction: Chronic kidney disease (CKD) leads to tubular injury, kidney fibrosis and anemia. These conditions are influenced by fibrotic and anti-fibrotic substances, such as Transforming Growth Factor beta-1 (TGF-β1), Hepatic Growth Factor (HGF), and Bone Morphogenic Protein-7 (BMP-7). Yacon is an herbal medicine which has not been elucidated in CKD. This study aimed to investigate the effect of ethanolic extract of Yacon leaves on attenuating renal injury in CKD model in mice. Methods: We performed 5/6 subtotal nephrectomy (SN) in male Swiss-Webster mice (3 months old, 30–40 grams) to induce chronic kidney disease, then the mice were sacrificed at day 14. The mice (n=25) were divided into five groups: one SN group, three groups of SN with administration of Yacon extract, and one group of sham operation (SO, with supplementation of 0.1% aquadest). There were three different doses of ethanolic extract of Yacon leaves: 98 mg/kg BW (SN+YK1), 49 mg/kg BW (SN+YK2), and 24.5 BW mg/kg (SN+YK3). Tubular injury, perivascular and interstitial fibrosis were quantified based on histopathological examination. Reverse-transcriptase PCR (RT-PCR) was performed to quantify HGF and BMP-7. Results: SN group demonstrated CKD with elevation of creatinine level, anemia, tubular injury, glomerulosclerosis, and fibrosis. Yacon extract treatment showed attenuation of injury with lower creatinine level, tubular injury, glomerulosclerosis and fibrosis compared to the SN group. HGF and BMP-7 mRNA expressions were higher in Yacon-treated groups than the SN group. Conclusion: Yacon treatment might ameliorate CKD through reducing fibrosis and increasing expression of anti-fibrotic genes.

Pattern of buccal and palatal bone density in the maxillary premolar region: an anatomical basis of anterior-middle superior alveolar (AMSA) anesthetic technique

Background@#The anterior-middle superior alveolar (AMSA) anesthetic technique has been reported to be a less traumatic alternative to several conventional nerve blocks and local infiltration for anesthesia of the maxillary teeth, their periodontium, and the palate. However, its anatomic basis remains controversial. The present study aimed to determine if the pattern of cortical and cancellous bone density in the maxillary premolar region can provide a rationale for the success of the AMSA anesthetic technique.Method: Cone-beam computed tomography scans of 66 maxillary quadrants from 34 patients (16 men and 18 women) were evaluated using a volumetric imaging software for cortical and cancellous bone densities in three interdental regions between the canine and first molar. Bone density was measured in Hounsfield units (HU) separately for the buccal cortical, palatal cortical, buccal cancellous, and palatal cancellous bones. Mean HU values were compared using the Mann-Whitney U test and one-way ANOVA with post-hoc analysis. @*Results@#Cancellous bone density was significantly lower (P ≤ 0.001) in the palatal half than in the buccal half across all three interdental regions. However, there was no significant difference (P = 0.106) between the buccal and palatal cortical bone densities at the site of AMSA injection. No significant difference was observed between the two genders for any of the evaluated parameters. @*Conclusions@#The palatal half of the cancellous bone had a significantly lower density than the buccal half, which could be a reason for the effective diffusion of the anesthetic solution following a palatal injection during the AMSA anesthetic technique.

Anaesthetic outcomes in neonatal surgical care in a tertiary health facility in Nigeria

ABSTRACT: There is always a concern about the survival of new-borns undergoing corrective surgical procedure early in life. Perioperative care, especially in sick babies, is challenging, and this makes ascribing outcomes to care given difficult. This study was aimed at determining and evaluating factors associated with poor outcomes in new-borns undergoing surgery and anaesthesia. This was a retrospective case notes review of 37 neonates who received general anaesthesia during surgical care over a three-year period. After ethical approval for the study, the demographic data, indications for surgery, American Society of Anesthesiologists' (ASA) classifications, preoperative, intraoperative and postoperative challenges present in these neonates as well as their outcome were extracted. A total of 48 neonates were operated over a three-year period, and only 37(77.1%) case files were available for review. Male: Female ratio was about 2:1, the two most common procedures performed were bowel resection and anastomosis in 7(18.9%) and colostomy 7(18.9%). Overall mortality was 29.7%. Neonatal mortality was significantly higher in patients with postoperative sepsis (p=0.006) and respiratory challenge (p=0.035). The median time to death was 9 days. Only one (9.1%) patient died within 24hours postoperative. Mortality in neonates undergoing surgical procedure early in life is very high in this study. However, it is difficult to implicate anaesthesia in our study as the cause of mortality as most occurred very late after many days of surgery. Availability of postoperative elective ventilation for selected patients may improve outcome

Efficacy of bleomycin for non-operative treatment of cervical lymphangioma in University of Ilorin Teaching Hospital, Nigeria

Background: Lymphangiomas are the developmental defects of the lymphatic channels, and they are most commonly found in the head and neck regions. Late presentation, rejection of surgery, and traditional scarification result in fatal complications. Surgical excision often thought to give immediate relief and aesthetic results is associated with damage to contiguous structures and recurrence, hence, the need for less invasive treatment modality. Objective: To assess the effectiveness of bleomycin sclerotherapy of cervical lymphangiomas. Materials and Methods: This is a prospective study of patients with cervical lymphangioma treated with sclerosant injection between January 2008 and December 2016. Preinjection ultrasound scan and initial ultrasound-guided aspiration of the fluid in the swelling (which many times is multiloculated) using a 20G cannula into a 10 ml syringe were performed. The cannula tip is retained in the space and intralesional injection of double-diluted bleomycin 0.5 i.u./kg body weight was given as outpatient at 2­4-weekly interval. Postinjection events were documented. The clinical assessment of the pre- and postinjection of sclerosant was performed. Result: A total of 23 patients were recruited, and six were females and 17 were males. All swellings were noticed at birth but median time at presentation was 17 days. All patients but one (95.8%) had complete clinical resolution after 1­4 courses of sclerotherapy for 4­16 weeks. Only one patient had residual nodule that required surgical excision. Redundant skin and hyperpigmentation from skin wrinkle were the early effects noticed in three patients; however, these were cosmetically acceptable to the parents. No recurrence was recorded. Conclusion: The treatment of cervical lymphangiomas with intralesional bleomycin injection is shown to be effective. It is safe and associated with no complication. This treatment modality and outcome was found to be acceptable to the parents of these children

Pharmacological evaluation of smooth muscle relaxant and cardiac-modulation potential of Phyla nodiflora in ex-vivo and in-vivo experiments

OBJECTIVE@#To investigate the pharmacological basis of its uses of Phyla nodiflora (P. nodiflora) for the treatment of anomalies predominantly by smooth muscle containing tissues such as gastrointestinal/vascular/broncho spasm and cardiovascular modulation.@*METHODS@#The crude hydroalcoholic extract of P. nodiflora (Pn.Cr) and its fractions were evaluated on isolated rabbit jejunum, rat trachea, aorta and atrium. To access the contractile or relaxant effects of testing materials, the tissues were mounted in isolated organ bath and responses were recorded with transducers coupled with data acquisition system. BALB/c mice were challenged with castor oil for the assessment of in-vivo antidiarrheal activity. Normotensive rats were used for in-vivo hypotensive study.@*RESULTS@#Hydroalcoholic extract of Pn.Cr at variable concentrations inhibited the natural spontaneous rhythm and 80 mmol/L K mediated contractions in isolated segment of jejunum with EC values of 3.18 and 1.91 mg/mL respectively. Verapamil, a Ca channel blocker, demonstrated akin pattern in jejunum and therefore possibly suggesting calcium blocking activity. On isolated rat tracheal tissue, Pn.Cr showed relaxation of high-K and carbachol mediated contractions (EC values: 1.24 and 2.42 mg/mL). Pn.Cr treatment relaxed the rat aortic ring in a cumulative doses with high-K and phenylephrine-induced contractions (EC values 0.25 and 0.92 mg/mL). Activity based fractionation of Pn.Cr showed that dichloromethane fraction was more potent for relaxing the tissues spasm compared to aqueous fraction. In-vivo experiments, significant protection by Pn.Cr (P < 0.05) was observed in castor oil-induced diarrhea (50-500 mg/kg) whereas hypotensive effect in anesthetized rats was seen at the dose range of 1-10 mg/kg of Pn.Cr (P < 0.05).@*CONCLUSION@#This study suggests the blockage of calcium channel in the smooth muscles as a pharmacological application to make usage of P. nodiflora in the management of diarrhea, asthma and hypotensive effect.

Three new anthraquinone derivatives isolated from Symplocos racemosa and their antibiofilm activity / 中国天然药物

Three new alkyl substituted anthraquinone derivatives, trivially named as symploquinones A-C (Compounds 1-3) were isolated from Symplocos racemosa. The structures of these compounds were determined on the basis of extensive spectroscopic analyses (UV, IR, Mass, H- and C-NMR, and two-dimensional (2D) NMR techniques). The resulting data were also compared with the reported literature. These compounds were then subjected to antibacterial or antibiofilm testing. Compounds 1 and 3 exhibited good antibacterial activity in the concentration range of 160-83 μg·mL against Streptococcus mutans, methicillin resistant Staphylococcus aureus and Proteus mirabilis. Both compounds were further screened for anti-biofilm activity, which revealed promising activities at sub-MIC concentrations. None of the compounds were found to be active against Klebsiella pneumoniae.

Pregnancy outcome variables and associated factors in different nationalities living in Kuwait

This study aimed to investigate differences in pregnancy outcome among various nationalities residing in Kuwait. Cross-sectional data were collected from 369 mother–infant dyads at delivery on mother height [MH], mother haemoglobin [mHb], child haemoglobin [cHb], mid-upper arm circumference [MUAC], gestational age [GA], placental weight [PW], birth weight [BW], crown–heal length [CHL], and head circumference [HC]. Significant differences among various nationalities were observed in mHb, HC, CHL, PW and MH. Kuwaiti and Indian women had lower PW and their babies had lower HC and CHL. Prevalence of anaemia [Hb <11.0 g/dL] ranged from 7.1% [Lebanese] to 30.0% [Kuwaiti] with the overall prevalence of 19.5%. Prevalence of low birth weight was 3.5%. Multiple linear regression analysis revealed PW as a significant predictor of BW, CHL and HC. Significant differences among various nationalities were observed in mHb, HC, CHL, PW and MH.The significance of these differences and their contributing factors needs further research

Effects of supplemental boron on intestinal proliferation and apoptosis in African ostrich chicks / Efectos del boro suplementario sobre la proliferación intestinal y apoptosis en polluelos de avestruz africana

Boron is an essential trace element which plays an important role in process of metabolism and the function of the tissues. However, the effects of boron on the intestinal cells in African ostrich chicks are poorly reported. Therefore, this study was designed to investigate the role of boron on proliferation and apoptosis of the intestinal cells. A total of 36, ten day-old ostrich chicks were randomly divided into six groups and fed on the same basal diet supplemented with 0, 40, 80, 160, 320 and 640 mg/L boric acid in drinking water for 80 days. Proliferatingcell nuclearantigen (PCNA) wasused to test the proliferation indexof intestine in different group byimmunohistochemicalstaining (IHC). Apoptoticcellsofintestinewere detectedbyDutp-biotin nick end labeling (TUNEL) reaction and evaluated by integral optical density (IOD). Results showed that proliferationof intestinal cells significantly increased in groups of 80, 160, 320 and 640 mg/L. TUNEL reaction showed that apoptosis significantly decreased in 80 mg/L groups, while significantly increased in high dose of boron groups (320 and 640 mg/L), especially inepithelium. In conclusion, low dose of boron-supplemented water could promote cell proliferation and depress apoptosis, while high dose of boron could cause intestinal apoptosis and thus we found increased proliferation of intestine cell as a compensatory adaption. These findings may support optimal dosage of boron that could protect the development of ostrich intestine, while high dosage of boron could suppress it, or even has toxic effects on it.

El boro es un elemento esencial que desempeña un importante rol en el proceso del metabolismo y en la función de los tejidos. Sin embargo, existe poca información de los efectos del boro en las células intestinales de polluelos de avestruz Africana. Por lo tanto, este estudio fue diseñado para investigar el papel del boro sobre la proliferación y la apoptosis de las células intestinales. Un total de 36 polluelos de avestruz de diez días se dividieron, aleatoriamente, en seis grupos y se alimentaron con una misma dieta basal suplementada con 0, 40, 80, 160, 320 y 640 mg/L de ácido bórico en agua potable durante 80 días. Se utilizó el antígeno nuclear celular de células en proliferación (PCNA) para probar el índice de proliferación de intestino en diferentes grupos por tinción inmunohistoquímica. Las células apoptóticas del intestino fueron detectadas por dUTP-biotina nick etiquetado para reacción (TUNEL) y evaluadas por la densidad óptica integrada (DOI). Los resultados mostraron que la proliferación de las células intestinales aumentó significativamente en los grupos de 80, 160, 320 y 640 mg /L. La reacción TUNEL mostró que la apoptosis se redujo significativamente en los grupos de 80 mg/L, mientras que el aumento fue significativo en grupos tratados con dosis alta de boro (320 y 640 mg/L), especialmente en el epitelio. En conclusión, la baja dosis de boro en agua suplementada podría promover la proliferación celular y deprimir la apoptosis, mientras que altas dosis de boro podrían provocar apoptosis intestinal y, por lo tanto, se halló una mayor proliferación de las células del intestino como una adaptación compensatoria. Estos hallazgos indican que una dosis óptima de boro podría proteger el desarrollo del intestino del avestruz, mientras que altas dosis de boro podrían suprimirla, o incluso tener efectos tóxicos sobre ella.

Age and gender specific stroke risk factors in a teaching hospital in Khyber Pakhtunkhwa

To determine age and gender specific stroke risk factors in a teaching hospital in Khyber Pakhtunkhwa. A hospital based descriptive study was performed in medical units of Lady Reading Hospital, Peshawar, from July 2011 to March 2012. A total of 100 patients of 18 years and above and of both genders were included. Study patients with first-ever acute stroke were divided into three groups; Group A young adult [<40 years], Group B, middle-aged [40-60 years], and Group C elderly [>60 years]. In these 03 groups, stroke risk factors were compared. Patients were assessed for hypertension, ischemic heart disease, hyperlipidemia, atrial fibrillation, diabetes mellitus and smoking. SPSS version 18.0 was used for statistical analysis. A sample of 100 patients was taken comprising 68% males and 32% females. Study patients had a mean age of 63.44 +/- 13.849. There were 08 patients in Group A, 29 in Group B, and 63 patients in Group C. Overall, hy-pertension was found in [62%], followed by smoking [47%], coronary artery disease [33%], diabetes mellitus [28%], hyperlipidemia [24%] and atrial fibrillation [21%]. Pattern of distribution of stroke risk factors is age and gender specific. Majority were found to have hypertension. Hypertension, diabetes mellitus, atrial fibrillation and hyperlipidemia differ significantly among the 03 age groups. Smoking was significantly different in males and females

Haemoperitoneum post colonoscopy in a continuous ambulatory peritoneal dialysis patient

We present the case of a patient on peritoneal dialysis [PD] who had an uneventful oesophagogastroduodenoscopy and colonoscopy. His peritoneal dialysis after colonoscopy had bright red peritoneal dialysate. The patient was completely asymptomatic and a CT scan was performed which did not reveal any retroperitoneal haematoma and showed no signs of perforation or splenic tear. His PD dialysate cleared up with time. We do not find any such case in the literature in which a patient has had haemoperitoneum after a colonoscopy without any obvious cause to account for it. Our patient was unique due to his CAPD in combination with his immunosuppression for his kidney transplant which may have predisposed him to the intraperitoneal bleed after colonoscopy or it may just have been a normal phenomenon after colonoscopy. More studies need to be done as the realisation of its pathology can prevent unnecessary testing and avoid patient and healthcare worker's anxiety

Antibiotic sensitivity pattern of Salmonella serotypes in patients with enteric fever in a teaching hospital

To determine the sensitivity of salmonella serotypes to antibiotics in patients with enteric fever. This descriptive study was carried out in medical units of Lady Reading Hospital Peshawar from January 2008 to December 2011. Patients were included by consecutive sampling technique. Blood samples were collected from patients with clinically suspected enteric fever and were sent to hospital laboratory for culture and sensitivity[C/S]. Salmonella colonies were identified using standard biochemical tests including fermentation of glucose, negative urease reaction, lysine decarboxylase, negative indole test, H2S production, and fermentation of dulcitol. Serological confirmation tests included polyvalent antisera for flagellar and somatic antigens. Antibiotic susceptibility was checked by Kirby- Bauer disc diffusion method for 22 antibiotics. Blood cultures of 106[61%] patients out of 173 patients were positive for salmonella species. Salmonella Typhi was found in 54.7% while salmonella paratyphi A in 32.1% and B in 13.2%. The sensitivity of salmonella species for ceftriaxone and ceftazidime was found to be 100%, followed by imipenem[98.1%] and meropenem [96.2%]. The sensitivity of drugs like amoxicillin, chloramphenicol and co-trimaxazolewere 2.8%, 12.3% and 22.6% respectively. Regarding quinolones, most sensitive was moxifloxacin49.1%, followed by ciprofloxacin 48.1%. Salmonella typhi was fully sensitive to meropenum, ceftriaxoneand cetazidime while paratyphi A or B was fully sensitive to ceftriaxone, ceftazidime and imipenem. The sensitivity of salmonella species was very low to the first line agents such as amoxicillin, chloramphenicol and co-trimaxazole. Salmonella species were fully sensitive to third generation cephalosporins such as ceftriaxone and ceftazidime

Community-based study of circumcision practices in Nigeria

Background: Circumcision practice around the world has various implications and has generated a lot of debate about the pros and cons of the practice. Nigeria is one of the countries where male and female circumcision practice still occurs however, there has been claim of reduction in female genital cutting. Congregational or 'group' circumcision prevails in some communities as a means of upholding traditions and commemoration of festive period. Objective: To determine the pattern of circumcision practice and identify factors affecting the practice in Ilorin community. Materials and Methods: The study was a descriptive, cross sectional study conducted among parents of under-5 children of both the sexes using pre-tested, semi-structured questionnaires, which were administered to the respondents by trained research assistants over a six-week period. Clinical examination of genital area in index child of each respondent was done by a pediatric surgeon, who was the principal investigator. Results: Three hundred and ninety three (93%) respondents completed the questionnaire and the same number of index children's external genitalia was examined by the pediatric surgeon. The mean age of respondents was 33.2±9.3 years, and the main source of family income was private enterprises and civil services. The circumcision status of fathers was 100%, mothers, 65.6%, and overall female-child circumcision rate was 46.7%. Though, most of the index children were delivered at health centers (72.3%), the circumcisions were performed at almost equal frequencies by traditional circumcisionists (39.8%) and doctors (39.2%), with more than half of the circumcision being done outside the hospital. The mean age at circumcision was 22 ±0.69 months, with 73.9% of girls as against 91.7% boys being circumcised by the age of five years. Family choice was the main determinant of the age at circumcision and the circumcisionist. Female circumcision was done by traditional circumcisionist, nurses, and doctors in 1 in 4, 1 in 5, and 1 in 10 cases of circumcision, respectively. Traditional open (classical) circumcision technique was mostly used (40.4%), followed by Plastibel TM (ring type) (32.6%), and 'group' circumcision was practiced among 41.2% of respondents. Post-circumcision complications were seen in 116 (33.7%) of circumcised children examined. Conclusion: Circumcision practice in Ilorin is still higher among the traditional circumcisionists, despite of high hospital delivery. Female circumcision and 'group' circumcision were also being practiced, using mainly the traditional open circumcision technique. The high rate of circumcision complications indicate the need for proper enlightenment and retraining of health care providers and traditional circumcisionists on the safe methods available. The government should involve the religion and opinion leaders in the community to assist in the prevention of negative and harmful traditional practices including female circumcision

Outcomes of surgical treatment of malrotation in children

Background: Urethral mucosal prolapse is rare. This condition may be confused with tumour or sexual abuse in girls. This study aims at reporting the pathology presentation and therapeutic options of urethral prolapse in girls. Materials and Methods: A retrospective study was undertaken from January 2000 to December 2008. Authors analysed the clinical features and the treatment options. Results: There were nine cases of urethral prolapse. The ages ranged from 2.5 to 10 years (mean age: 5.08 years). The main presentation was vaginal bleeding (five cases). Physical examination revealed a soft; non-tender mass that bleeds on touch (six cases); with a length ranging from 0.75 to 1 cm. Urine culture in four patients revealed urinary infection that yielded Escherichia coli in three cases and the Staphylococcus aureus in one case. Six patients had surgical treatment while three had medical treatment. In those who had surgery; one had acute urine retention and one had recurrence that was treated successfully without operation. All the nine girls are cured. Conclusion: Urethral prolapse is a disease of the prepubertal girls of low socio-economic group. Diagnosis is clinical. The treatment of choice is surgical

A prototype treatment plant was fabricated and tested at varied hydraulic retention times for settling the suspended/settleable matter and skimming out oil and grease at laboratory plants of 40 L and 56 L. The results showed that 99.7% of oil and grease and almost all total suspended solids were removed and sparkling clear water was obtained, reusable for washing vehicles

Gastrointestinal duplications: experience in seven children and a review of the literature

Enteric duplication [ED] is a rare congenital anomaly that can occur anywhere along the alimentary tract from the mouth, down to the anus and the nearby organs. This uncommon anomaly may be asymptomatic or presents with vague symptoms mimicking other common pathologies. We aim to present our experience, management challenges and patterns of ED with a review of the literature. The study was carried out at a Nigerian Tertiary Hospital [2005-2008 inclusive]. We retrospectively analyzed seven patients with ED managed in our hospital for sex, age, clinical presentations, duplication size and site, presence of ectopic tissue, complications, associated anomalies, radiological workups, and prognosis. Data was analyzed using SPSS 11.0 for window. Seven children between the age range of 44 hours-10 years had ED, one sublingual and six intraabdominal duplications. Midgut volvulus with long segment bowel gangrene complicated two cases. The diagnosis was incidental in all. Three cases were diagnosed following conventional radiological contrast examination and the rest at surgery. Ultrasound was not helpful in making diagnosis in all the six intraabdominal duplications. Though surgery was recommended for all, one of the patients declined. Only one patient had unsuccessful surgery. ED requires high index of clinical suspicion and careful management. Many cases of nonspecific abdominal pains should be properly evaluated before patients suffer avoidable complications

Bowel resection in Nigerian children

Background : Although bowel resections are commonly done for congenital malformations in children in developed countries; they usually follow neglected and preventable acquired diseases of the intestine in developing countries. Objectives : To determine the indications and outcome of bowel resections in children of a developing country in a university teaching hospital. Materials and Methods: Data of the patients operated (from birth to 15 years) was retrospectively collected over eight years (January 1999 to December 2006). The biodata of children included the following: Indications for operation; type of operations; duration of admission; and outcome of treatment including complications. Patients with Hirschsprung's disease were excluded from the study because bowel resection forms part of their definitive surgical management. Results : There were 70 patients (38 boys and 32 girls). The age ranged between four hours to 15 years (median; five months). There were 16 (22.9) neonates; 26 (37.1) infants; and 28 (40) grown children. The indications were congenital anomalies in the 16 neonates. Also; 23 (88.5) infants had intussusception; 2 (7.7) had midgut vovulusm and 1 (3.8) had congenital small intestine band. Among the grown children; typhoid ileal perforation (TIP) was seen in 14 (50.0); intussusception in 5 (17.9); and other causes in nine patients. Overall; intussusception was the most common indication for bowel resection; followed by TIP. A total of 24 patients developed 33 complications. Complications included wound infection in 47.8and anastomotic leak in 42.8. The duration of admission ranged between 4-35 days (median; 15 days). The overall mortality was 17.1-; which was highest among neonates (56.3); followed by the infants (26.9-). Conclusion : Bowel resections are mainly done for intussusception and complications of TIP at our centre. Late presentation; preexisting malnutrition; and nonavailability of parenteral nutrition contributed to unacceptable morbidity and mortality

Pediatric day case surgery: Experience from a tertiary health institution in Nigeria

Background : The general observation that children achieve better convalescence in the home environment supports the need for adoption of day case surgery, which is gaining considerable acceptance in developing countries. Pediatric surgical service is in great demand in developing countries, and in-patient beds and surgical supplies are insufficient. Method : A prospective collection of data on all pediatric day surgeries (PDSs) by the pediatric surgical unit University of Ilorin Teaching Hospital (UITH, Ilorin, was done. Parents had pre-operative outpatient briefing and postoperative interviews on the second and ninth days for consultation regarding post-operative complications and events at home. Study period was between April 2005 and September 2007 (2½ years). Results : Of the 660 elective cases, 449 (68.02%) children were recruited as day cases. The male-to-female ratio was 14.3:1. Age ranged between 20 days and 15 years with a mean of 37.6 months and standard deviation (SD) of 34.4 months. Congenital hernias/ hydroceles were the highest indications (71.2%), followed by lump/ masses (12.9%), undescended testes (8.7%), umbilical hernias (4.8%) and thyroglossal duct cyst (2.5%). In 98.9% of cases, the parents resided within 20 km radius of the hospital, and 91.5% of them could reach the hospital within 1 hour. Fathers and mothers of 80.1% and 77.1% of children, respectively, had above-primary education. More than half of the fathers (55%) were civil servants, while 30% were self-employed. The mothers were civil servants in 37.3% of cases, and 34% were self-employed. The average number of outpatient clinic visits before surgery was 2-3 visits (41.2%) with mean interval to surgery of 4-5 weeks (60.3%). Logistics (investigations and availability of operation list) and patient's fitness for surgery were statistically significant delay factors (P= 0.001). Conclusion : Parents reported 14 children to be irritable at home due to pain, while the others reported satisfactory day case experience. No unplanned admission or mortality was recorded, and only 3 (0.8%) parents would not recommend day case surgery to other people. Conclusion: Pediatric day case surgery is feasible for well-selected and monitored cases in our environment. Term neonates with informed parents are suitable for pediatric day case surgery. There is a need for a day case center to reduce waiting list at UITH
