The opinions and assertions expressed herein are those of the authors and are not to be construed as official or as reflecting the views of the Department of the Air Force or the Department of Defense. Objective: The ameloblastic fibro-odontoma (AFO) is an uncommon odontogenic tumor occurring in childhood with limited reported data on recurrence. The purpose of this AFO study was to review its clinicopathologic features, investigate treatment modalities and establish a recurrence rate. Study Design: The clinicopathologic features of 12 new cases of AFO were analyzed and compared with those of 208 cases from the literature, with special emphasis on the clinical behavior, treatment, and recurrence rate. Results:The average age was 9.4 (±6.7) years with a male-to-female ratio of 1.6:1. The mandible was the site of occurrence in 59.5%. The tumor most often presented radiographically as a unilocular mixed density lesion associated with the crown of an impacted tooth. Displacement of teeth, delayed eruption and bony expansion were commonplace. There were 5 recurrences among 68 cases with adequate follow-up for a recurrence rate of 7.4%. All recurrences were attributed to incomplete removal at the time of the initial surgery.Conclusions: The AFO is a childhood tumor most often affecting the posterior jaws and frequently causing bony expansion with profound affects on the dentition. Conservative surgical removal with extraction of the associated teeth is recommended. The established recurrence rate is less than 10%.

Abstract OBJECTIVES The goal of this study was to investigate the prevalence of Birt–Hogg–Dubé (BHD) syndrome in patients with familial spontaneous pneumothorax (FSP) and the clinical characteristics of pneumothorax related to BHD syndrome compared with those of primary spontaneous pneumothorax. METHODS A total of 37 families diagnosed with FSP from 2007 to 2017 were enrolled in this study. The FLCN gene, which is responsible for BHD syndrome, was sequenced using the Sanger method in 25 probands. For the patients with confirmed BHD syndrome-related pneumothorax, clinical characteristics including the median onset age of pneumothorax, the male-to-female ratio, the mean height and body mass index (BMI) and the recurrence rate after different treatment modalities were obtained and compared with those of patients with primary spontaneous pneumothorax. RESULTS Of the 25 probands with FSP, 16 [64.0%, 95% confidence interval (CI) 43.8–84.2%] harboured FLCN germline mutations. In the patients with BHD syndrome-related pneumothorax, the median onset age of pneumothorax was 34 years; the male-to-female ratio was 1.3:1; and the mean height and BMI were 167.0 ± 8.6 cm and 23.6 ± 3.4 kg/m2, respectively. These characteristics were significantly different from those in patients with primary spontaneous pneumothorax from the same centre. The recurrence rate of BHD syndrome-related pneumothorax after conservative therapy was 53.1% (95% CI 38.6–67.5%) compared with 9.1% (95% CI 0–19.4%) after surgical treatment. CONCLUSIONS BHD syndrome is one of the most common causes of FSP. Patients with FSP should be recommended for mutation screening for the FLCN gene to facilitate early diagnosis and proper intervention.

Supernumerary teeth and odontomas are obstacles for spontaneous tooth eruption and may result in impaction. The aim of the study is to present a conservative treatment approach for impacted teeth following surgical obstruction removal by reviewing three treatment modalities: surgery only, which involves the surgical removal of the obstruction and the spontaneous eruption; surgery with immediate traction, which includes surgery combined with immediate active orthodontic brace cementation and traction; and surgery with delayed traction, which combines a surgical procedure of obstacle removal and orthodontic brace cementation with follow-up for the spontaneous eruption. The first two modalities require orthodontic traction either by an additional surgical procedure for orthodontic brace cementation, or combined with the surgical obstacle removal. With the third approach, clinical follow-up is performed via connected ligature wire elongation applied during the surgical procedure for the spontaneous emergence of the impacted tooth. Active orthodontic traction is only employed if the tooth fails to erupt. The visual follow-up via wire elongation serves as a reference during the emergence of the impacted teeth and reduces the need for radiographic examination. The surgical-orthodontic approach saves both further surgery and orthodontics (spontaneous eruption) or further surgery (in failure to erupt).

✓ Cerebral sparganosis is a rare parasitic disease caused by infestation by the plerocercoid larva of Spirometra mansoni. The authors retrospectively analyzed 17 cases of cerebral sparganosis treated at Seoul National University Hospital between 1986 and 1994. The patients' ages at diagnosis ranged from ± to 57 years (median 32 years) and the male/female ratio was 13:4. Diagnosis was based on radiological findings, serological test results, operative findings, and histopathological examinations. Characteristic magnetic resonance (MR) findings consisted of widespread white matter degeneration and cortical atrophy, mixed-signal lesion (low in the central and high in the peripheral regions on T2-weighted images) with irregular dense enhancement of central foci and changes in the location and shape of the enhancing lesion in follow-up studies. Ten patients underwent surgical removal of the parasitic lesion, six received medical treatment alone (five with praziquantel and one with antiepileptic drugs), and one underwent insertion of a ventriculoperitoneal shunt and a course of praziquantel. Follow-up periods ranged from 13 to 111 months (mean 49 months). Seven patients who underwent complete removal of the lesion, live worm, or degenerative worm with surrounding granuloma showed a favorable course. Patients who received medical treatment alone or incomplete removal exhibited progression in their neurological deficits and their seizures could not be controlled. Medication with praziquantel seemed to have no killing effect on live worms. The authors conclude that MR imaging is the most valuable modality for the early detection of cerebral sparganosis and that complete surgical removal of granuloma together with worms, whether they are alive or degenerative, is the treatment of choice.

Due to the frequent development of non-infectious complications after surgical removal of the third lower impacted tooth, many techniques are used to reduce their severity. Among them is the technique of applying platelet-rich fibrin to the post-extraction alveolus. The study included 90 consecutively enrolled patients. Eligible patients were randomly assigned to two groups: patients with and without platelet-rich fibrin introduced into the postoperative alveolus. Pain, swelling, trismus, and temperature were evaluated after the procedure. Pain intensity was significantly higher in the control group than in the study group at 6 h, 1, and 3 days after surgery. PRF application did not significantly affect the intensity of swelling. Body temperature was significantly higher in the control group than the study group on day two after surgery. The trismus was significantly higher in the control group than in the study group at one, two, and seven days after surgery. Application of the PRF allows for a faster and less traumatic treatment process. It will enable for speedier recovery and return to active life and professional duties.

Abstract Context.—Orthokeratinized odontogenic cyst (OOC) is a relatively uncommon developmental cyst comprising about 10% of cases that had been previously coded as odontogenic keratocysts. Odontogenic keratocyst was designated as keratocystic odontogenic tumor (KCOT) in the new World Health Organization classification and OOC should be distinguished from KCOT for differences in histologic features and biologic behavior. Objective.—To analyze the clinicopathologic features of 61 cases of OOC in a Chinese population. Design.—Clinicopathologic analysis was performed on 61 cases of OOC. Immunohistochemical expression of Ki-67 and p63 was evaluated in 15 OOCs and 15 typical KCOTs. Results.—The 61 patients with OOC ranged from 13 to 75 years (average, 38.93 years). The lesions developed mainly in the third and fourth decades (57.38%) with a distinct predilection for males (72.13%). Six (9.84%) lesions were found in the maxilla and 55 (90.16%) in the mandible. The most common sites were in the mandibular molar and ramus region. Of the 54 cases with radiographic record, 47 (87.04%) were unilocular and 7 (12.96%) were multilocular radiolucencies. Twenty-seven of the 54 cysts were associated with an impacted tooth. Follow-up of 42 patients revealed no recurrence during an average period of 76.8 months after surgery. Compared with KCOTs, expression level of Ki-67 and p63 was significantly lower in OOCs, suggesting a lower proliferative activity. Conclusion.—Orthokeratinized odontogenic cyst is clinicopathologically distinct from KCOT and should constitute its own clinical entity.

Abstract Background Colorectal cancer (CRC) is one of the leading causes of mortality and morbidity in the world. It is the third most common malignancy after lung & breast and the fourth leading cause of cancer-related deaths worldwide, accounting for approximately 1,400,000 new cases and about 700,000 deaths worldwide. Objectives The aim of this retrospective study is to compare the epidemiology, clinicopathologic features, different treatment modalities and outcomes regarding disease free survival (DFS), progression free survival (PFS) & overall survival (OS) of colorectal cancer disease between cases presented to Ain shams university hospital & to Luxor international hospital in 3 consecutive years. Patients and Methods The study is retrospective comparative study. Clinical oncology department in Ain Shams University Hospital and Luxor International Hospital. The data Collected from January 2013 to December 2015. This study analyzed hospital records of patients who diagnosed with colorectal cancer (CRC) and allocated into two groups: Group A: CRC patients presented to Ain-Shams University Hospital from January 2013 to December 2015, group B: CRC patients presented to Luxor International Hospital from January 2013 to December 2015. Results There was no statistically significant difference regarding age parameter in LIH when compared to ASU, but the study was consistent with higher incidence in patients who were aged more than forty- accounted about 70.5% in all CRC cases. Cases less than 40 years old, in group A were 35.2%, while in Group B were 23.5%. Even there was no statistically significant difference but it may be attributable to more westernization in Lower Egypt. Other explanation may be due to decreased low socioeconomic status and different lifestyle factors in more developing region what increase risk of colorectal cancer. Among our cases, there is no statistically significant difference regarding gender between the two hospitals. Both sexes almost were affected equally, females appeared to be at a slightly higher risk of developing CRC cancer with current prevalence 1.3:1 in ASU group, and 1.1:1 in LIH group. Conclusion The need to increase awareness about CRC in Egypt especially upper Egypt, is recommended. An awareness campaign should be performed to promote detection of CRC at its earliest and most curable stage by recognizing early symptoms and enabling early referrals for colonoscopy. Those at higher risk should be offered more intensive surveillance. Similarity of the data from different centers suggests that this is the picture of colorectal cancer typical of Egypt.

Introduction: Diagnosis and management of impacted mandibular third molars call for a cogent appraisal and treatment choice both for the sick person and the dental practitioner. This academic work scrutinized the pattern as well as treatment of impacted mandibular third molars at the Teem Clinic and Dental Centre, Ekpan, Delta State, in Nigeria.Materials and Methods: This cross-sectional survey involved 131 cases who reported impacted mandibular third molars. The age, gender, impacted tooth, type of impaction, pathological conditions, and treatment proffered were recorded.Results: The male to female ratio was 0.8:1, with an age range of 10 to 40 years. Of the lower third molar impactions 58 (42.0%) were mesioangular, 5 (3.6%) horizontal, 18 (13.0%) vertical and 57 (41.3%) were distoangular. A total of 47 (34.1%) quested for dental attention following varying degrees of pain induced by pericoronitis. Teeth removal was accomplished for 76 (55.0%) owing to carious lesions on the impacted teeth, proximate tooth, or both. Surgical extraction was the option taken in 69 (50.0 %) with caries on the impacted teeth while 3 (2.2%) had to pull out of their teeth done owing to carious lesions on the bordering second molars. In 3 (2.2%) both the impacted third molar and the proximate second molar were decayed. Conclusions: The prevailing indication for pulling out impacted mandibular third molars was acute pericoronitis. Mesioangular sort of impaction was most recurrent and ought to be considered for theplausibility of frequentness of complications.

Introduction: There is no exact statistics about the incidence of colorectal cancer in Bangladesh. According to National Cancer Institute, London, it is the 2nd most common cancer affecting more than 30,000 people in each year. As many patients with colon cancer do not develop symptoms until it is advanced and detection in early stage can only be achieved by screening of asymptomatic person. Maximum patients present lately with distance metastases when there is nothing to treat except palliative therapy. Objectives: To identify the risk factors, early symptoms, signs, treatment modalities, operative outcome, morbidity and mortality rate. Materials and Methods: This retrospective study was carried out at CMH Dhaka during August 2002 to August 2004. A total of 50 patients were taken as study sample. All the patients were admitted in different surgical units of CMH Dhaka for surgical treatment. Detailed history were taken on admission by a questionnaire and examined thoroughly and findings regarding Anaemia, Jaundice, Dehydration, Oedema, Lymphadenopathy, Nutritional status and abnormal signs like ascites, distension, rigidity, organomegaly recorded. Digital rectal examination were done in all cases and finally examined by Proctoscope, Sigmoidoscope and with Colonoscope. FOBT (Fecal Occult Blood Test), serum tumour marker was also assessed. Results: Out of 50 cases 22 were rectal carcinoma and next common site was caecum and number was 10. There was a variation in the sex ratio. Out of 50 cases 33 were male and 17 were female. The highest incidence was among people of 6th decade (28%) and next highest was in 4th decade (24%). Majority of patient with right colon cancer presented with abdominal pain 12 out of 22 cases (56%) and weight loss 15 cases (68%). For left colon cancer commonest symptom was weight loss and weakness and altered bowel habit. Almost all cases with rectal carcinoma presented with bleeding per rectum. Conclusion: About 50% of lesions were found in recto-sigmoid junction and male: female ratio was 1.9:1. All efforts and modern technology should be applied for early detection and treatment. The survival rate is usually very poor in rectal carcinoma. In this study most of the cases were subjected to post operative Chemo and Radiotherapy, but more were treated with neoadjuvant chemoradiation for down staging. The need for early detection of Colorectal Carcinoma (CRC) should be stressed in the form of screening patient awareness and understanding about symptomatology. Early diagnosis and definitive treatment are thereby increasing expectation of higher survival and better prognosis in patient of colorectal carcinoma.

Surgical Difficulty

The extraction of impacted third molars is among the most common surgical procedures carried out in the field of Oral and Maxillofacial Surgery. Both the patient and dentist must therefore have scientific evidence-based information concerning the estimated level of surgical difficulty of every case to consider in referring cases of impacted third molars for specialists’ handling. We have undertaken a study in which demographic and radiological variables were considered together to evaluate the risk factors for surgical difficulty in a cohort of 100 impacted mandibular third molars. There were 13 variables evaluated for surgical difficulty. Total surgical time intervention was noted at the end of each surgery. Each variable was analysed with total surgical time intervention with univariate and multiple linear regression. Out of 13 variables, 9 were found statistically significant. The most significant predictors for surgical difficulty were Body Mass Index, Depth of impacted tooth and Retromolar space. No postoperative complications were reported.

Background: Pituitary surgery is the most common surgery used to remove pituitary tumours. The use of mini doppler in surgical removal of an endonasal pituitary tumour has shown good short-term clinical outcomes and few complications in patients. Cavernous sinus invasion limits the surgical excision and still a challenge of gross total resection.   Objective: The main objective of this study is to evaluate the outcome of surgical removal of an endonasal pituitary tumour using mini doppler.    Method: A total of 12 patients were studied retrospectively from 2012 to 2018 in a single institution (Private hospital) in Dhaka, Bangladesh. The male and female ratio was 7:5. Results: 92% of cases of the total number of patients had satisfactory removal/ neurological improvement/hormonal improvement. Among 12 cases, 8 cases had transient diabetes insipidus and one patient had CSF leak.    Conclusion: The intraoperative Doppler is a useful tool to localize the carotids, which provides safer resection of endonasal pituitary tumours. Thus, it is very safe and effective for laterosellar resection of recurrent pituitary tumours and for cavernous sinus invasions.
