Treatment of advance keratoconus using donor bowman layer: the zaman technique of bowman layer transplantation (Type I & Type II)

Published on: 6th May, 2022

Commonly referred to as an ecstatic, non-inflammatory disease, Keratoconus, usually bilateral and asymmetric, is characterized by progressive steeping and thinning of the cornea. This results in irregular astigmatism which compromises vision [1,2]. Traditionally, early Keratoconus stages have been treated by prescribing a hard contact lens to obtain a regular anterior optical surface. This tendency was discontinued when contact lens intolerance in advanced stages required the use of penetrating keratoplasty (PKP) or deep anterior lamellar Keratoplasty (DALK). An alternative technique of corneal cross-linking was designed in 2003 as a treatment option for keratoconus. The cornea measured at least 400 um thickness after epithelium removal and pre-operative maximum keratometry (Kmax) measured 58D or less. As a result, no corneal transplantation was required or postponed [3].

Fetal Alcohol Spectrum Disorders – What does it mean?

Published on: 17th March, 2020

OCLC Number/Unique Identifier: 8566852662

Prenatal alcohol exposure is one of the most important causes of preventable cognitive impairment in the world. The developing neurological system is exquisitely sensitive to harm from alcohol and there is now also substantial evidence that alcohol-related harm can extend beyond the individual person, leading to epigenetic changes and intergenerational vulnerability and disadvantage [1].

Harmonic oscillation picture of the free electron Zitterbewegung in vacuum

Published on: 3rd May, 2022

As shown e.g. in ref.[1] Zitterbewegung (trembling motion) of the free Dirac electron is generated if transitions between positive and negative energy states occur. Here we treat this effect in a single-mode configuration using a density matrix method. As compared with more elaborate conventional treatments, this method allows an easy estimate of the amplitude of the motion. The result is by predicted spreads of the free electron charge.

Management of gestational diabetes during ‘COVID19 time’

Published on: 27th May, 2020

OCLC Number/Unique Identifier: 8605985151

The measures put in place by many governments around the world to fight the spread of COVID-19 have drastically reduced visits to diabetes centres. To keep providing people with diabetes the professional support they need and reduce the inconvenience caused by the interruption of traditional assistance, the typical control visit can be carried out by virtual visit, telemedicine (TM) that should have the necessary characteristics to provide a correct execution. Especially this is important for pregnant women first diagnosed with gestational diabetes mellitus (GDM), they have the necessity to frequent checks in a short time due to the pregnancy.

Types and Outcomes of Diagnostic Measures provided for women Presented with Postmenopausal Bleeding

Published on: 21st April, 2025

Background: Postmenopausal bleeding (PMB) is bleeding from the genital tract after 12 months of amenorrhea in a woman over the age of 50, or 24 months if below the age of 50 years, in 10% of women presented with PMB, the cause is endometrial cancer.Purpose: To assess the clinical presentation types and outcomes of diagnostic measures provided for women presenting with PMB at Saad Abu-Alela Hospital, Khartoum, Sudan.Methodology: It was a descriptive, cross-sectional study conducted at Saad Abu-Alela Teaching Hospital in the period from January to December 2022.An interview questionnaire was used for data collection. Fifty-nine (59) postmenopausal women were included in this study, age, parity, risk factors, duration of bleeding, duration of menopause, ultrasound findings, and hysteroscopy findings were recorded.Results: The majority of study participants were aged between 50-54 years, menopause duration was most 1-4 years, most of the participants were educated and medically free, DM and HTN, and most of the participants were multiparous. Duration of PMB ranged between weeks in a third of cases and up to more than a year in some cases, amount of bleeding was mild in more than half. Ultrasound is used to assess the endometrial thickness and other findings, also hysteroscopy and biopsy or Dilation and curettage and hysterectomy.Conclusion: The ultrasound and endometrial biopsy via inpatient hysteroscopy and dilatation and curettage were the best tools for evaluation of (PMB), benign conditions were the most frequent outcome and endometrial cancer.

Cranio-Facial Fibrous Dysplasia: A case report of a conservative treatment in a monostotic form associated with an orthodontic management and a bone graft of the non-lytic bone area for dental implant rehabilitation

Published on: 21st November, 2019

OCLC Number/Unique Identifier: 8405070202

Fibrous dysplasia is an osteolytic lesion in which bone is replaced by an instable fibrous osseous tissue. The aim of this case report is to highlight dental rehabilitation (bone grafts to allow dental implant) on patients suffering of this condition. A 39-year-old female with a hard-traumatic event in childhood desired a dental implant rehabilitation on her teeth 19 and 30 after an orthodontic alignment. A Cone-Beam Computed Tomography (CBCT) was performed showing a massive radiopaque lesion of the anterior mandible. The bone grafts and dental implants were successfully managed. A non-invasive treatment with regular follow up was chosen for this case. No evolution was noticed twenty-four month later at the follow up CBCT.

Local recurrence after enlarged total nephrectomy

Published on: 5th April, 2019

OCLC Number/Unique Identifier: 8056337130

Local isolated recurrence of kidney cancer in the renal lodge after radical nephrectomy is rare and has a poor prognosis. Surgical excision, sometimes even extended to neighboring organs, is currently the only effective treatment for local recurrence of kidney cancer. The interest of new medical therapies remains to be defined. We report a case of local recurrence in a patient with radical nephrectomy.

Acute abdomen as complication of a knee arthroscopy: A case report

Published on: 22nd December, 2020

OCLC Number/Unique Identifier: 8872656452

A knee arthroscopy in spinal anaesthesia was performed on a 67 years old male patient. During the procedure the patient was hemodynamically stable, until he suddenly turned pale and started complaining of severe pain in lower abdomen with signs of guarding. The procedure was finished as urgently as possible and after releasing the tourniquet we noticed significant difference in volume of the leg, with redness distal to tourniquet. Urgent lab results were essentially unremarkable and the patient was sent for the urgent radiological diagnostics. CD of the left leg described fluid in the soft tissues of the thigh, scrotum, and abdomen; and the unenhanced CT of the abdomen showed free fluid along the entire femoral shaft of the left thigh, extending towards pelvis and abdomen to perihepatic and perisplenic space, and retroperitoneum, with gas bubbles tracking along anterior aspect of the left thigh into the left retroperitoneum. He was admitted to the ICU, and within few hours all symptoms have resolved and his further recovery was without complications.

Anasarca in a 35 year old man- A diagnostic dilemma

Published on: 17th July, 2019

OCLC Number/Unique Identifier: 8198742700

Anasarca is generalized swelling of the body following accumulation of fluid in the extracellular compartments. It may result from multiple aetiology mainly of renal, hepatic or cardiovascular origin. The aim of this case report is to highlight the challenges encountered in making diagnosis in a patient with anarsaca. We report a case of a 34 year old transporter who presented with anasarca. He had clinical features and risk factors suggestive of renal, hepatic and cardiovascular disease. However investigations ruled out renal, hepatic or cardiovascular diseases as the aetiology of the anarsaca. The anarsarca was also noted to be unresponsive to diuretics. The diagnosis of the disease causing the anarsaca was therefore a dilemma.
