This study was carried out to evaluate the influencing factors that affect the reproductive performance of cows at the Monirampur upazila in Jessore district of Bangladesh. A total of 224 cows were brought to the upazila livestock hospital for artificial insemination (AI). The cows were inseminated between 12 to 18 hours from the onset of estrus and data was obtained from the owner. Out of 224 cows, 133 became pregnant and 91 were non pregnant. In this study, the overall pregnancy rate was 59.29%. Among the age variability, the highest pregnancy rate (70.27%) was at the age of 4 years old. In case of breed variation, the highest pregnancy rate was observed in local breed (69.07%) compared with other crossbred cows. Hence the breed variations significantly influence the conception rate of cows. According to the parity, we found that the pregnancy rate was increasing with their parity but decreasing after 4th parity. The highest conception rate was observed in 3rd parity (67.74%) which was significantly higher than that of heifers (Parity-0). Here we also found that the types of bull semen used for AI had no significant effect for pregnancy rate. The skills of AI technician for AI to cows were significantly affecting the pregnancy rate. However, this study is not enough for rating and comment about the reproduction performance of cows. Therefore, further extensive study is needed for rating and recommendation for the cattle up gradation at that particular area.

Background: Thromboangiitis obliterans (TAO) poses a higher risk of amputation than atherosclerosis obliterans. It is characterized by onset at a relatively young age. There are currently no clear treatment guidelines for TAO other than smoking cessation. In this study, we aimed to identify factors that could influence a favorable prognosis of TAO. Methods: From January 2009 to December 2019, we retrospectively reviewed the initial symptoms, characteristics, treatments, and disease course of 37 patients (45 limbs) with TAO. Logistic regression analysis was performed to investigate factors affecting the course of symptoms that persisted or worsened despite treatment. Results: Patients' mean age was 37.2±11.4 years, and all patients were men. The mortality rate was 0% during the follow-up period (76.9±51.1 months). All patients were smokers at the time of diagnosis, and 19 patients (51.4%) successfully quit smoking during treatment. When comparing the Rutherford categories before and after treatment, 23 limbs (51.1%) showed improvement, the category was maintained in 11 limbs (24.4%), and 11 limbs (24.4%) worsened. Symptom persistence or exacerbation despite treatment was associated with a higher initial Rutherford category (odds ratio [OR], 1.59; 95% confidence interval [CI], 1.04-2.42; p=0.03) and a higher score of the involved below-knee artery at the time of diagnosis (OR, 2.26; 95% CI, 1.10-4.67; p=0.03). Conclusion: The degree of disease progression at the time of diagnosis significantly affected patients' prognosis. Therefore, early diagnosis and intervention are important to improve the course of TAO.

Purpose: Bell's palsy is characterized by sudden onset of unilateral facial weakness. The use of corticosteroids for childhood Bell's palsy is controversial. This study aimed to identify clinical characteristics, etiology, and laboratory findings in childhood Bell's palsy, and to evaluate the efficacy of corticosteroid treatment. Methods: We conducted a retrospective analysis of children under 19 years of age treated for Bell's palsy between January 2009 and June 2017, and followed up for over 1 month. Clinical characteristics, neuroimaging data, laboratory findings, treatments, and outcomes were reviewed. Patients with Bell's palsy were divided into groups with (group 1) and without (group 2) corticosteroid treatment. Differences in onset age, sex, laterality, infection and vaccination history, degree of facial nerve palsy, and prognosis after treatment between the groups were analyzed. Results: One hundred patients were included. Mean age at presentation was $7.4{\pm}5.62years$. A total of 73 patients (73%) received corticosteroids with or without intravenous antiviral agents, and 27 (27%) received only supportive treatment. There was no significant difference in the severity, laboratory findings, or neuroimaging findings between the groups. Significant improvement was observed in 68 (93.2%) and 26 patients (96.3%) in groups 1 and 2, respectively; this rate was not significantly different between the groups (P=0.48). Conclusion: Childhood Bell's palsy showed good prognosis with or without corticosteroid treatment; there was no difference in prognosis between treated and untreated groups. Steroid therapy in childhood Bell's palsy may not significantly improve outcomes.

Biliary atresia (BA) is very difficult to distinguish from neonatal hepatitis (NH) and its prognosis depends on the age at the time of Kasai operation. Therefore early differentiation between these two conditions is very important. Although various clinical and laboratory tests have been reported to differentiate between them, they are still of limited value. From 1980 to 1999, forty-five infants were referred to our pediatric surgical unit for operation for suspected BA. Eight patients underwent Kasai operation immediately because of late diagnosis. These were excluded from the study. The clinical history, physical findings. radiologic and laboratory examinations of 37 cases were analyzed retrospectively. The average age of BA (n=20) was $55.1{\pm}16.7$ days, and that of NH (n=17) was $55.8{\pm}15.6$ days. The sex ratio of BA was 13:7, and that of NH was 14:3. All the patients had obstructive jaundice and acholic stool except 4 BA and 6 NH patients. Acholic stool with yellow component was more frequent in NH. Onset of jaundice was within 2 weeks after birth in 85 % of BA, and in 65% of NH. The onset of acholic stool was within 2 weeks after birth in 60 % of BA, and in 23.5 % of NH. The duration of jaundice and acholic stool of BA were $50.9{\pm}16.6$ days and $41.3{\pm}18.4$ days and those of NH were $40.1{\pm}23.1$ days and $26.6{\pm}25.4$ days respectively. The ultrasonogram and hepatobiliary scan were useful, but not a definitively reliable method for the differentiation of these two diseases. There was no difference in laboratory data. Seventeen cases had NH among 45 referred cases for Kasai operation with the clinical impression of BA, and 4 cases of 17 NH cases needed to be explored to rule out BA. In conclusion. false positive rate of clinical impression of BA was 37.8 %. and negative exploration rate was 8.9 %, Therefore. careful clinical observation for 1-2 weeks by an experienced pediatric surgeon was very important to avoid unnecessary operation to rule out NH up to the age of 8 - 10 weeks. so long as the stool had yellow component.

목 적: 위장관 증세 위주로 발현하는 우유 알레르기(cow's milk allergy with predominantly gastrointestinal symptoms, CMA-GI)는 유발시험 후 유해반응의 발현시간이 즉각적이지 않아 병력청취를 통하여 우유와 발현 증상의 관련성을 의심하기가 쉽지 않다. 또한, 가벼운 구토, 설사 증상부터 괴사성 장염의 발병처럼 높은 사망률을 보이는 경우까지 임상적 스팩트럼이 다양하며, 감염성 질환 등 타 질환과의 철저한 감별진단이 요구되나 어려운 경우가 많다. 저자들은 CMA-GI를 3가지 임상유형으로 분류하여 진단적 효용성을 높이고, 효율적인 치료계획 수립에 도움을 주고자 본 연구를 시행하였다. 대상 및 방법: 1995년 3월부터 1997년 6월까지 대구효성가톨릭대학병원 소아과에 급, 만성 설사 등 위장관 증세를 주소로 내원하여 우유제거 및 유발시험의 반응을 근거로 CMA-GI로 진단된 30명(남 22명, 여 8명)의 영유아를 대상으로 우유 유발시험에 따른 유해반응의 발현시기 및 양상에 따라 3가지 임상 유형으로 분류하고, 입원당시 임상소견, 유해반응의 양상, 면역학적 검사소견, 소장 생검조직의 형태학적 분석 등을 이용하여 각 유형을 비교 관찰하였다. Quick (Q)형은 우유 유발시험 후 1시간 이내에 두드러기형 발진 등이 발현한 경우로, Slow (S)형은 유해반응이 1시간에서 24시간사이에 발현한 경우로, Quick & Slow (Q&S)형은 Q형과 S형의 증상이 함께 나타나는 경우로 분류하였다. 결 과: 1) 대상환아 30명 중 Q형 5례, S형 20례, Q&S형 5례로, S형의 환아가 가장 많았다. 2) 입원당시 연령은 Q형 $81.4{\pm}67.1$일, S형 $31.9{\pm}12.7$일, Q&S형 $366.0{\pm}65.0$일로 각 유형에 따라 호발 연령의 차이를 보였다(p<0.05). 입원당시 체중은 Q형 10~50백분위수, S형 10백분위수 이하, Q&S형 10~25백분위수로 S형과 다른 유형간에 차이를 보였으며(p<0.05), S형 환아 중 90%에서 3백 분위수 이하로 관찰되었다. 3) 입원당시 말초혈액검사상 백혈구수는 Q형 $5,700{\sim}12,300/mm^3$, S형 $10,000{\sim}33,400/mm^3$, Q&S형 $5,200{\sim}14,900/mm^3$로 S형과 다른 유형간에 차이를 보였다(p<0.05). 입원당시 혈중 알부민치는 Q형 $4.2{\pm}0.4\;g/dl$, S형 $3.0{\pm}0.3\;g/dl$, Q&S형 $4.0{\pm}0.3\;g/dl$로 S형과 다른 유형간에 차이를 보였으며(p<0.05), S형 환아 중 85%에서 혈중 알부민치가 3.5 g/dl 이하였다. 4) 소장 조직생검의 형태학적 분석에서 융모의 높이는 Q형, Q&S형은 정상 대조군과 유의한 차이를 보이지 않았으나, S형에서는 의미있는 감소를 보였으며(p<0.05), 45%에서 아전 융모위축(subtotal villous atrophy), 55%에서 부분(partial) 융모위축의 소견이 보여 전례에서 장병증(enteropathy) 소견이 관찰되었다. 5) 추적 관찰 중 타 음식물에 대한 알레르기의 발현은 S형의 환아군에서는 환아의 연령, 전신 상태의 불안정과 위험성 등 윤리적 측면을 고려하여 유발시험을 시행하지 않았으며, Q형에서도 환아의 연령을 고려하여 다양한 유발시험은 제한하였으나, 대개 우유, 대두유, 이유식 분유, 계란 등 1~2가지의 음식물에 유해 반응을 보이는 것으로 관찰되었다. Q&S형군에서는 연령에 따른 이유 식이의 필요성에 따라 다양한 유발시험을 시행하였으며, 계란, 감자, 새우 등 해산물, 두부, 사과, 당근, 쇠고기, 닭고기 등 환자에 따라 다양한 음식물에 유해반응을 보이는 것으로 관찰되었다. 6) 입원당시 혈중 IgE치, 호산구수, 우유단백 RAST치, 콩단백 RAST치, 피부반응검사는 유형간에 차이를 보이지 않았다. 결 론: 위장관 증세 위주로 발현하는 우유 알레르기는 유발 시험에 따른 유해 반응의 발현 시기 및 양상에 따라 3가지 유형으로 분류될 수 있으며, 이들의 임상소견, 소장생검조직 소견, 면역학적 검사 소견, 타 음식물에 대한 알레르기 발현 유무 등에서 각 유형별로 특징적인 임상 양상을 관찰할 수 있으며, 이들 소견을 비교, 분석하여 감별 진단하는 것이 CMA-GI의 진단 및 치료적 접근에서 효용성이 높을 것으로 판단된다.

Background: Adnexal torsion results in ischemia of structures distal to twisted pedicle and acute onset of pain is responsible for about 3% of all gynecologic emergencies. Ovarian torsion classically occurs in a pathological enlarged ovary, as with cancer, but diagnosis remains a challenge. Objective: Our purpose was to evaluate clinical risk factors predictive of torsion with gangrenous adnexa. Material and methods: A retrospective descriptive study and chart review of surgically proven ovarian torsion/adnexal torsion cases at the Obstetrics and Gynecology Department of Prapokklao Hospital, Chanthaburi, Thailand between January 2011 and December 2015 was conducted. Result: Seventy-eight cases were identified. Mean age at presentation was 35.5 years. The average maximum diameter of the ovarian tumors was 10.8 cm. The percentage of gangrenous ovarian cysts in this study was 46.2 (36/78). The precision to determine the pathological site by patient, physician and ultrasonography was 8.5, 24.2 and 83.3 percent, respectively with statistically significant variation. Conclusion: Ovarian/adnexal torsion remains a challenge condition especially in young nulliparous women. Sophisticated investigation does not guarantee ovary preservation. Combining clinical acumen, appropriate tests and detailed consideration may be the best practice at the present time.

Objective : The purpose of this study is to evaluate the clinical characteristics and surgical outcome of cerebellopontine angle (CPA) epidermoids presenting with trigeminal neuralgia. Methods : Between 1996 and 2004, 10 patients with typical symptoms of trigeminal neuralgia were found to have cerebellopontine angle epidermoids and treated surgically at our hospital. We retrospectively analyzed the clinico-radiological records of the patients. Results : Total resection was done in 6 patients (60%). Surgical removal of tumor and microvascular decompression of the trigeminal nerve were performed simultaneously in one case. One patient died due to postoperative aseptic meningitis. The others showed total relief from pain. During follow-up, no patients experienced recurrence of their trigeminal neuralgia (TN). Conclusion : The clinical features of TN from CPA epidermoids are characterized by symptom onset at a younger age compared to TN from vascular causes. In addition to removal of the tumor, the possibility of vascular compression at the root entry zone of the trigeminal nerve should be kept in mind. If it exists, a microvascular decompression (MVD) should be performed. Recurrence of tumor is rare in both total and subtotal removal cases, but long-term follow-up is required.

Painful legs and moving toes (PLMT) syndrome is characterized by spontaneous movements of the digits and pain in one or both lower extremities. Of the reported cases, a majority of the patients was female, and the mean age of onset was 58 years. Only one pediatric case has been reported so far. Herein, we report the first adolescent case of PLMT in Korea. A 16-year-old girl complained of tingling pain in the left leg and involuntary movement of the ipsilateral great toe one month after a second untethering surgery. Three years ago, she had undergone untethering surgery to correct lipomeningomyelocele at the S2 level of the conus medullaris. At that time, she was diagnosed with polyradiculopathy at the left L5 level with axonal involvement. We diagnosed her with PLMT syndrome and prescribed gabapentin. Her symptoms diminished within a day. Complete relief from involuntary movement of the toe was achieved within four months. PLMT is a rare syndrome but it should be considered in the differential diagnosis of children and adolescents with limb pain and spontaneous movement in their toes.

목 적 : 갑상선호르몬은 소아에서 뇌의 발달에 매우 중요한 호르몬이므로 갑상선기능이상에 대한 조기진단 및 치료는 중요하다. 미숙아에서는 이러한 갑상선의 기능이상이 만삭아에 비해 많이 발생한다. 본 연구의 목적은 미숙아에서의 갑상선기능이상의 빈도, 임상양상 및 경과 등을 알아보고자 하였다. 방 법 : 1999년 4월에서 2008년 8월까지 단국대학교병원 신생아중환자실에 입원한 37주 미만의 미숙아 802명 중 초기 갑상선기능검사의 결과를 확인 할 수 있었던 599명의 환아를 대상으로 의무기록을 통해 후향적으로 연구하였다. 1, 2차 검사의 결과에 따라 정상군, 일차성 갑상선기능저하증군, 고갑상선자극호르몬혈증군, 저티록신혈증군, 지연된 일차성 갑상선기능저하증군, 지연된 고갑상선자극호르몬혈증군의 6군으로 나누었다. 각 군 간의 임상특징, APGAR 점수 및 여러 위험인자들, 검사결과 등을 비교하였고 갑상선기능이상의 빈도 및 경과, 위험요소 등을 분석하였다. 결 과 : 599명중 1차 갑상선기능이상을 보인 환아는 136명(23%)이었고 저티록신혈증이 20%로 가장 많았다. 처음 NST는 정상이었으나 생후 3-4주경 2차 검사를 시행한 46명 중 8명(17%)에서 갑상상선기능이상을 보였다. 갑상선호르몬은 총 10명에서 투여되었고, 9명에서는 호전을 보여 중단이 가능하였다. 1명은 이소성 갑상선으로 지속적인 복용이 필요한 상태이다. 결 론 : 미숙아에서 갑상선기능 이상은 매우 흔하였고, 대부분 일시적이었다. 때로는 초기 검사에서 정상이었다가 뒤늦은 이상을 보일 수 있으므로 미숙아의 경우 특히 33주 미만 또는 2,500 g 미만의 경우 처음 검사가 정상이더라도 3-4주경에 재검하는 것은 필요하다고 생각한다.
