The tibialis anterior tendon functions as a major dorsiflexor of the ankle. A rupture in this tendon can cause serious problems in the ambulatory function. A closed traumatic rupture without open wound or an atraumatic rupture can delay diagnosis and treatment. There are not enough guidelines for an effective surgical treatment on this chronic condition. Herein, we report two cases of chronic tibialis anterior disruption successfully treated by semitendinosus autograft.

Although rare, hypodermic needle fractures can occur in the maxillofacial region. In cases of fracture, urgent intervention is required to prevent further complications. We present the case of a 37-year-old female patient with a fractured needle in the left sublingual fossa during a lingual nerve block 6 months before referral. The fragment of a 30-gauge needle was located using cone-beam computed tomography and retrieved under local anesthesia with blunt dissection. The patient recovered uneventfully, except for predictable postoperative inflammatory complications, which resolved within 2 weeks. Precautions should be implemented to prevent needle fractures, which are usually preventable. However, if the retrieval is unsuccessful, the patient should be referred to a well-equipped surgical unit without delay.

수술전 방사선 조사는 불가능한 수술을 가능케 하며, 암의 크기를 축소시켜 수술범위를 감소시킬 수 있어 조직 및 장기의 보존과 기능을 유지할 수 있게 한다. 그러나 수술의 성과는 완전한 창상의 치유없이는 이루어질수가 없으며 수술전에 시행하는 방사선조사는 창상의 회복을 불완전하게 만들거나 지연시키는 것으로 알려져 있어 문제점으로 대두되고 있다. 본 연구는 252마리의 마우스 좌우측 하지 상단 내측 피부에 일회 2000cGy의 방사선조사를 실시 한후 즉시, 1, 2, 4, 8, 12, 16, 20주후에 외과적 피부절개 및 봉합과 유사한 창상을 만들었고, 그후 일정한 간격으로 창상의 장력강도 측정과 병리학적 관찰을 하고 방사선조사와 수술이 시행될때까지의 시간적 간격과 창상 치유정도의 상관관계를 분석하여 다음과 같은 결론을 얻었다. 1. 방사선 조사직후와 1주, 2주내에 창상이 발생된 경우에는 장력강도의 최고치의 발현 및 상승속도가 지연되어 통계학적으로 의의가 있었다. 2. 방사선 조사후 $4\sim8$주내에 창상이 발생되었을 경우 장력강도의 변화는 대조군과 비교해서 별다른 차이가 없었다. 3. 방사선 조사후 12,16,20주내에 창상이 발생되면 장력강도의 최고치의 발현과 상승 속도가 약간 지연되었다. 4. 대조군에 비해 방사선조사군의 창상의 장력 강도 평균치는 모든 관찰기간동안 감소되었다. 5. 병리조직학적 소견상 상피세포는 방사선조사군에서도 정상적인 속도로 재생되었으며 섬유아세포 및 교원질의 출현시기는 대조군에 비해서 약간 지연되었으나 장력강도의 상승과 교원질량간에 상관관계가 존재함을 추정할 수 있었다. 6. 방사선 조사후 창상 발생의 관찰기간이 경과함에 따라 장력강도의 평균치가 오히려 감소됨은 영양과 전신상태에 관련있는 것으로 생각되었다. 그러므로 수술전 고선량의 방사선 조사를 시행하면, 창상치유는 지연시키며 특히 방사선조사 직후, 1주 및 2주후에 수술을 시 행할 경우 창상치유를 심하게 지연시킬 수 있고, 또 12, 16,20주후에도 역시 창상치유의 지연을 예상할 수 있겠다. 그러나 $4\sim8$주후에 수술을 시행하면 별부작용없이 창상 치유가 가능하므로 가장 적절한 수술시기 라고 생각한다.

Background: Breast cancer is known to be one of the most prevalent cancers among women in both developing and developed countries. The incidence of breast cancer in Pakistan has increased dramatically within the last few years and is the second country after Israel in Asia to have highest proportional cases of breast cancer. However, there are limited data for breast cancer available in the literature from Pakistan. Objectives: The study was conducted to bring to light the common clinical presentation of breast cancer and to evaluate the frequency of established risk factors in breast carcinoma patients and furthermore to compare the findings between premenopausal and postmenopausal women in Pakistan. Materials and Methods: A 6 months (from July 2012 to Dec 2012) cross sectional survey was conducted in Surgical and Oncology Units of Civil Hospital, Karachi. Data were collected though a well developed questionnaire from 105 female patients diagnosed with carcinoma of breast and analyzed using SPSS version 17. Institutional ethical approval was obtained prior to data collection. Results: Out of 105 patients, 43 were premenopausal and 62 were postmenopausal, 99 being married. Mean age at diagnosis was $47.8{\pm}12.4years$. A painless lump was the most frequent symptom, notived by 77.1%(n=81). Some 55.2% (n=58) patients had a lump in the right breast and 44.8%(n=47) in the left breast. In the majority of cases, the lump was present in upper outer quadrant 41.9% (n=44). Mean period of delay from appearance of symptoms to consulting a doctor was $5.13{\pm}4.8months$, from the shortest 1 month to the longest 36 months. Long delay (> 3 months) was the most frequent figure 41.9%. Considering overall risk factors most frequent were first pregnancy after 20 years of age (41%), physical breast trauma (28.6%), lack of breast feeding(21.9%), and early menarche <11 years (19%), followed by null parity (16.2%), consumption of high fat diet (15.2%), family history of breast cancer or any other cancer in first degree relatives (9.5% and 13.3%, respectively). Some of the less common factors were late menopause >54 years (8.6%), use of oral contraceptive pills (10.5%), use of hormone replacement therapy (4.7%),smoking (4.7%) and radiation (0.96%). Significant differences (p<0.005) were observed between pre and post menopausal women regarding history of physical breast trauma, practice of breast feeding and parity. Conclusions: A painless lump was the most frequent clinical presentation noted. Overall age at first child > 20 years, physical breast trauma, lack of breast feeding, early menarche <11 were the most frequent risk factors. Physical breast trauma, lower parity, a trend for less breast feeding had more significant associations with pre-menopausal than post-menopausal onset. Increase opportunity of disease prevention can be obtained through better understanding of clinical presentation and risk factors important in the etiology of breast cancer.

The Transverse rectus abdominis musculocutaneous (TRAM) flap has been commonly used for autologous breast reconstruction. Despite these clinical usefulness, the TRAM flap is prone to partial flap or fat necrosis in especially pedicled flap. To improve flap survival, the surgical delay procedures and pharmacological treatments have been developed. In many studies for the pharmacological treatment, Lipo-$PGE_1$ has demonstrated a marked ability to improve flap survival and it's effect has been proved similar to surgical delay procedure. The purpose of this study is to determine the most effective route of Lipo-$PGE_1$ administration as a pharmacological treatment in TRAM flap of the rat. Fifty male Sprague-Dawley rats weighing 300-350 gm were divided into five groups, One week before flap elevation, Lipo-$PGE_1$($2{\mu}g/kg$) was injected three times in a week and than the left inferior epigastric vessel based TRAM flap ($5.0{\times}3.0cm$) elevated; group I: no procedure before flap elevation; group II: intraperitoneal injection; group III: intravenous injection; group IV: subcutaneous injection; group V: topical application. A flap was assessed at postoperative 7 days by comparison of flap survival rate, vessel counts(H-E stain), and vascular endothelial growth factor(VEGF) protein expressed by Western blot. The results demonstrated that the mean percentages of the flap survival area in group III were significantly higher than that of any other group(p<0.05). The vessel counts of all experimental groups were statistically higher than that of control group(p<0.05). Only in group III, the VEGF protein expression was increased significantly than control group and there are no difference in other experimental groups. In conclusion, the intravenous administration of the Lipo-$PGE_1$ is the most effective on flap survival, and the VEGF induced by Lipo-$PGE_1$ has some positive effects on new vessel formation and flap survival.

Background: In evaluation of craniosynostosis patients in terms of neurodevelopmental delay, positron emission tomography computed tomography (PET-CT) scan can be used to assess brain abnormalities through glucose metabolism. We aimed to determine the unnecessity of PET-CT in this study. Methods: Thirty-eight patients diagnosed with craniosynostosis who underwent distraction osteogenesis from October, 2010 to November, 2013 were reviewed. Magnetic resonance imaging (MRI) and PET-CT scan were carried out for evaluation of the brain structure and function, whereas X-ray and CT scan were taken for evaluation of the skull. Results: Nine patients reported abnormal MRI findings which were not significant, and five patients showed local problem on brain on PET-CT scan. No correlation was found among them. Conclusion: PET-CT evaluation of possible abnormal brain findings do not affect surgical planning or require additional therapy. Preoperative PET-CT scan is not the essential study to get any etiologic information of the disease consequences or to establish the treatment plan.

Purpose: Benign symmetrical lipomatosis(Madelung's disease) is a disease of uncertain etiology that manifests as massive lipomatous deposits in specific area of the body. It is usually located on the neck, shoulder, proximal regions of the extremities and the abdomen. Madelung's disease is found many in middle-aged, Mediterranean man. Imaging using either computed tomography or magnetic resonance imaging is often recommended. Dietary restriction provides no relief of disease. Abstinence with alcohol may delay further progression but does not regression tumor mass. The objective of this study is to prove effectiveness of liposuction for treatment of benign lipomatosis. Methods: We conducted liposuction as a treatment for benign lipomatosis. After general anesthesia, We conducted power assisted liposuction and amount of suctioned volume was about 2500 cc. After surgery, we did compressive dressing and then followed by pressure garment. Results: Six months after surgery, patient was examined for follow up at outpatient department. Recurred lipoma was not observated. Patient was satisfied with result.Conclusion: The only effective therapy for Madelung's disease is surgical removal but recurrence could be occurring. Also multiple surgical scars will be visible. We report a patient with multiple large lipomatosis successfully treated with liposuction.

Purpose: Tularemia is an infection caused by Francisella tularensis. Its diagnosis and treatment may be difficult in many cases. The aim of this study was to evaluate treatment modalities for pediatric tularemia patients who do not respond to medical treatment. Methods: A single-center, retrospective study was performed. A total of 19 children with oropharyngeal tularemia were included. Results: Before diagnosis, the duration of symptoms in patients was $32.15{\pm}17.8days$. The most common lymph node localization was the cervical chain. All patients received medical treatment (e.g., streptomycin, gentamicin, ciprofloxacin, and doxycycline). Patients who had been given streptomycin, gentamicin, or doxycycline as initial therapy for 10-14 days showed no response to treatment, and recovery was only achieved after administration of oral ciprofloxacin. Response to treatment was delayed in 5 patients who had been given ciprofloxacin as initial therapy. Surgical incision and drainage were performed in 9 patients (47.5%) who were unresponsive to medical treatment and were experiencing abcess formation and suppuration. Five patients (26.3%) underwent total mass excision, and 2 patients (10.5%) underwent fine-needle aspiration to reach a conclusive differential diagnosis and inform treatment. Conclusion: The causes of treatment failure in tularemia include delay in effective treatment and the development of suppurating lymph nodes.

It is well known that multipoint and computerized intraoperative mapping systems improve the results of surgery for Wolff-Parkinson-White syndrome and show tremendous potential for opening an entirely new era of surgical intervention for the more common and lethal types of supraventricular tachyarrhythmias such as atrial flutter and atrial fibrillation. In addition, the ability to map and ablate the sometimes fleeting automatic atrial tachycardia is greatly enhanced by computerized mapping systems. In this study, we have developed 64 channel computerized data analysis system using microcomputer (Macintosh IIx) for basic research of electrophysiology and electrical propagation. The bipolar electrogram information is acquired from 64 cardiac sites simultaneously at a sampling rate of 1ksamples/sec with continuous and total data storage of up to 30 seconds. When the reference electrogram is selected and reference point is picked up, delay time from the reference point in displayed on two dimensional diagram of the heart. System design permits easy expansion to almost 256 simultaneous sites, This system is expected to enable us to study pathophysiology of cardiac arrhythmia and to improve the results of diagnosis and surgical treatment for cardiac arrhythmia.

Purpose: Typical cross finger flap is still a good method for reconstruction of fingertip injuries. However, it is necessarily followed by great loss and aesthetically unpreferable result of donor finger. Hereby, we introduce a modification of cross finger flap with reduction pulp plasty and full thickness skin graft, with which we could reduce the defect size of injured fingertip and donor site morbidity at the same time, without any need for harvesting additional skin from other part of hand. Method: This method was performed in the patients with fingertip injuries of complete amputation or in case of loss of fingertip due to necrosis after replantation. Firstly, reduction pulp plasty was performed on the injured finger to reduce the size of defect of fingertip. Additional skin flap was obtained from the pulp plasty. Secondly, cross finger flap was elevated from the adjacent finger to cover the defect on the injured finger. At the same time, defect on the donor finger produced by the flap elevation was covered by full thickness skin graft with the skin obtained from the pulp plasty of injured finger. Results: Flap and graft survived without any necrosis after surgical delay and flap detachment. All of them were healed well and did not present any severe adversary symptoms. Conclusion: Cross finger flap with reduction pulp plasty and full thickness skin graft is an effective method that we can easily apply in reconstruction of fingertip injury. We think that it is more helpful than the usual manner, especially in cases of children with less soft tissue on their fingers for preservation and reduction of the morbidity of donor finger.
