Upper GI bleeding from GIST is rare in Africa. The C‐kit‐negative variant is uncommon worldwide. We report a case of a 42‐year‐old woman managed for upper GI bleeding secondary to stomach GIST, negative for CD117 but positive for DOG 1 and CD 34. The 1‐year postsurgery review is uneventful.

Background. Ghana began mandatory iodization of salt in 1996. This study compares the prevalence of thyroid disorders before and after the introduction of iodization. Methods. This is a retrospective study of thyroid cases from the middle belt of Ghana between 1982 and 2014. To demonstrate a link between iodization and hyperthyroidism and autoimmunity, we compared the prevalence of hyperthyroidism and autoimmune thyroid disorders before and after the iodization programme. Results. A total of 10,484 (7548 females, 2936 males) cases were recorded. The rate of thyroid cases seen was 343/100,000. Nontoxic nodular goiters (25.7%) and toxic nodular goiters (22.5%) represented the second commonest thyroid disorders recorded. The prevalence of hyperthyroid disorders seen after 1996 was significantly higher than the prevalence seen before the iodization (40.0 versus 21.1%, p<0.001). The prevalence of autoimmune disorders recorded after iodization was significantly higher than that before the iodization programme started (22.3% versus 9.6%, p<0.001). Conclusions. This study has revealed a significant increase in thyroid admissions in Central Ghana over the decades. A connection between iodine fortification and iodine-induced hyperthyroidism and between iodine fortification and autoimmune thyroiditis has been shown in this study. [ABSTRACT FROM AUTHOR]

Sclerosing stromal tumour (SST) is a rare benign sex cord stromal tumour of the ovary. We report a case of sclerosing stromal tumour of the mesentery in a 32-year-old Para one who presented with intra abdominal mass, menstrual irregularity and secondary infertility. Histopathology and immunohistochemistry of the completely excised tumour was consistent with sclerosing stromal tumour, immunoreactive only to vimentin. No ovarian tissue was found in the sectioned tumour. Her menses became regular and she conceived 3 months after complete excision and delivered after 9 months. Hormonal assay was not done because SST was least suspected. From literature this is the first case of SST in the transverse mesocolon reported in the West African subregion, and may probably be one of the rare cases of hormonally active SST.

Breast cancer is increasingly common among young women in Ghana. BCa is heterogeneous with unique traits that impact causes, prognostic, and predictive outcomes of patients before and after menopause. However, limited evidence exists on differences between young premenopausal (YPM) and postmenopausal cases in Ghana. This study compared breast tumour characteristics between YPM women (under 35 years) and postmenopausal women. We conducted a prospective cross-sectional study involving 140 BCa-diagnosed women at the Breast Care Clinic of Komfo Anokye Teaching Hospital (KATH), Kumasi from November 2019 to June 2021. Thirty-one (22.1%) of participants were YPM and 109 (77.9%) were postmenopausal. The median ages for YPM and postmenopausal were 32.0 (range: 25.0–35.0) and 57.0 (48.0–86.0) respectively. Invasive carcinoma was the most common histological type (97.1%). Left tumour location was the most frequent in both groups (51.6% for YPM and 51.8% for postmenopausal). Lumps detected were frequently in the outer upper quadrant in both groups (61.3% and 56.0%). The majority of the YPM women (80.7%) and postmenopausal women (87.0%) had stage III and IV diseases. Most YPM (64.5%) and postmenopausal women (64.4%) exhibited triple-negative breast cancer (TNBC). Both YPM 13 (56.6%) and postmenopausal participants 40 (56.3%) exhibited a predominantly partial response to neo-adjuvant chemotherapy but YPM women (21.7%) experienced disease progression than the postmenopausal women (12.7%). The study highlights consistent tumour characteristics and advanced clinical stages at diagnosis in both groups with a higher prevalence of TNBC. TNBC and HER2+ subtypes respond better to Anthracycline-based neoadjuvant chemotherapy. Establishing Breast Care Clinics in district and regional hospitals for early detection is crucial and further studies are warranted to understand the higher TNBC prevalence in black Africans and re-evaluate breast education programs to address the persistently late presentations.

Background: Diabetic foot remains a challenge in most low-middle-income countries (LMICs). A severe deficit in data exists on them in sub-Saharan Africa (SSA). Up-to-date data on the longitudinal trajectories and determinants can provide a benchmark for reducing diabetic foot complications in SSA. Objective: The primary objective of this study was to estimate trends in the incidence of diabetic foot and determine predictors in an adult Ghanaian diabetes cohort. Design: The study is a retrospective longitudinal study over a 12 year period. Methods: We applied Poisson regression analysis and Cox proportional hazard models to demographic and clinical information obtained from patients who enrolled in a diabetes specialist clinic in Ghana from 2005 to 2016 to identify longitudinal trends in incidence and predictors of diabetic foot. Results: The study comprised 7383 patients (63.8% female, mean follow-up duration: 8.6 years). The mean incidence of foot disorders was 8.39% (5.27% males and 3.12% females). An increase in the incidence of diabetic foot ranging from 3.25% in 2005 to 12.57% in 2016, p < 0.001, was determined. Diabetic foot, with adjusted hazard ratio (HR; 95% confidence interval (CI)), was predicted by disease duration, that is, for every 5-year increase in diabetes duration: 2.56 (1.41-3.06); male gender: 3.51 (1.41-3.06); increased body mass index (BMI), that is, for every 5 kg/m2: 3.20 (2.51-7.52); poor glycaemic control, that is, for every percentage increase in HbA1c: 1.11 (1.05-2.25), hypertension: 1.14 (1.12-3.21); nephropathy: 1.15 (1.12-3.21); and previous foot disorders: 3.24 (2.12-7.21). Conclusions: We have found a trend towards an increased incidence of diabetic foot in an outpatient tertiary diabetes setting in Ghana. Systemic and individual-level factors aimed at preventive foot screening as well as vascular risk factor control should be intensified in diabetic patients in Ghana and other LMICs.

Background: Gastrointestinal Stromal Tumour is a rare but potentially curable tumour of the gastrointestinal tract accounting for up to 1% of all gastrointestinal tumours. The discovery of Imatinib mesylate, a novel tyrosine kinase inhibitor has improved the chances even for unresectable, recurrent, or metastatic diseases. Methods: This study sought to document the clinical and pathological characteristics of GISTs from two tertiary hospitals in Ghana that have undergone immunohistochemistry confirmation between 2014 and 2021. Results: The median age of the subjects was 50 years with most of them (28.0%) being above 61 years. There were more females than males (64.0% vs. 36.0%). Abdominal mass and abdominal pain made up the majority of the clinical presentations. The majority of the subjects had partial gastrectomy (32.0%) which was followed by wedge resection (28.0%). Appendectomy and sleeve gastrectomy were the least performed procedures (8% each). Four of the 25 patients (16.0%) had resections of involved contiguous organs done with splenectomy being the most common procedure. The majority of GISTs were found in the stomach (68.0%) followed by the appendix (12.0%) and small bowel (12.0%). Gastrointestinal bleeding (55.8%) and abdominal pain (38.5%) were the most reported symptoms. Free resection margins were observed in 84.0% of the subjects and only 3/25 (12.0%) experienced tumour recurrence. Conclusion: GIST is a potentially curable tumour that once was obscure but currently gaining popularity. Surgical resection offers the hope of a cure for localized disease while targeted therapies is a viable option for recurrent, metastatic, or unresectable tumours. [ABSTRACT FROM AUTHOR]

Background Endocrine disorders have been noted to be on the increase in the developing world, but little is known about their outcomes on the African continent. Methods We conducted a retrospective longitudinal study to evaluate the demographic characteristics and determinants of endocrine-related mortality among adult patients over 9 y in a leading tertiary hospital in Ghana. We determined the predictors of inpatient mortality using Kaplan–Meier survival curves and Cox proportional hazard regression analysis. Results Overall, 6265 patients (9.7% of all medical admissions) were admitted with various endocrine disorders during the period. The most common endocrine cause of hospitalisation was diabetes mellitus (86.0%), followed in order of decreasing frequency by thyroid disorders (7.7%) and miscellaneous disorders (1.4%). The overall crude mortality rate of endocrine admissions was 16.7%. Death was predicted by increasing age with an adjusted hazard ratio of 1.25 (95% confidence interval 1.15 to 1.65) for every 10-y increase in age. Conclusions Almost one in six adults admitted with an endocrine disorder to a tertiary care centre in Ghana died in hospital, and many of the deaths were due to non-communicable disease complications. Enhanced public health disease prevention strategies and endocrine inpatient care processes are warranted. [ABSTRACT FROM AUTHOR]

Introduction: This study aimed to describe the epidemiology and outcomes of intestinal obstruction at a tertiary hospital in Ghana over time. Methods: Records of all patients admitted to a tertiary hospital from 2007 to 2011 with intestinal obstruction were identified using ICD-9 codes. Sociodemographic and clinical data were compared to a previously published series of intestinal obstructions from 1998 to 2003. Factors contributing to longer than expected hospital stays and death were further examined. Results: Of the 230 records reviewed, 108 patients (47%) had obstructions due to adhesions, 50 (21%) had volvulus, 22 (7%) had an ileus from perforation and 14 (6%) had intussusception. Hernia fell from the 1st to the 8th most common cause of obstruction. Patients with intestinal obstruction were older in 2007-2011 compared to those presenting between 1998 and 2003 (p < 0.001); conditions associated with older age (e.g. volvulus and neoplasia) were more frequently encountered (p < 0.001). Age over 50 years was strong factor of in-hospital death (adjusted OR 14.2, 95% CI 1.41-142.95). Conclusion: Efforts to reduce hernia backlog and expand the surgical workforce may have had an effect on intestinal obstruction epidemiology in Ghana. Increasing aging-related pathology and a higher risk of death in elderly patients suggest that improvement in geriatric surgical care is urgently needed. © 2015 S.

Poly (ADP-ribose) polymerase inhibitors (PARPi) are used for patients with BRCA1/2 mutations, but patients with other mutations may benefit from PARPi treatment. Another mutation that is present in more cancers than BRCA1/2 is mutation to the TP53 gene. In 2D breast cancer cell lines, mutant p53 (mtp53) proteins tightly associate with replicating DNA and Poly (ADP-ribose) polymerase (PARP) protein. Combination drug treatment with the alkylating agent temozolomide and the PARPi talazoparib kills mtp53 expressing 2D grown breast cancer cell lines. We evaluated the sensitivity to the combination of temozolomide plus PARPi talazoparib treatment to breast and lung cancer patient-derived tumor organoids (PDTOs). The combination of the two drugs was synergistic for a cytotoxic response in PDTOs with mtp53 but not for PDTOs with wtp53. The combination of talazoparib and temozolomide induced more DNA double-strand breaks in mtp53 expressing organoids than in wild-type p53 expressing organoids as shown by increased γ-H2AX protein expression. Moreover, breast cancer tissue microarrays (TMAs) showed a positive correlation between stable p53 and high PARP1 expression in sub-groups of breast cancers, which may indicate sub-classes of breast cancers sensitive to PARPi therapy. These results suggest that mtp53 could be a biomarker to predict response to the combination of PARPi talazoparib-temozolomide treatment. • We demonstrated that breast and lung patient derived tumor organoids (PDTOs) carrying mutant p53 (mtp53) present synergistic cytotoxicity to PARP inhibitor (PARPi) talazoparib and DNA damaging agent temozolomide. • Combination drug synergism was achieved when treating mtp53 containing, but not wild-type p53 expressing, PDTO. • Synergy resulted most likely from double-strand breaks in mtp53 expressing PDTOs that were not able to be repaired and subsequently led to cell death. • Breast cancer tissue microarrays (TMAs) showed a positive correlation between stable p53 and high PARP1 expression in sub-groups of breast cancers, which may indicate sub-classes of breast cancers sensitive to PARPi therapy. • We found that the combination drug synergism occurred in both breast and lung PDTO carrying wild type BRCA1/2 which demonstrated high strength for mtp53 as a significant biomarker. • This work suggests that in addition to BRCA1 mutation, TP53 mutation may be an additional predictor for cancer cell death following combination PARPi treatment.

Introduction: Diaphragmatic injuries may be associated with thoracoabdominal blunt or penetrating traumas. The diagnosis is often delayed, despite the availability of several medical imaging modalities. The surgical management remains controversial, in terms of the choice of surgical approach and the surgical repair technique. Aim: To evaluate the surgical management experience of traumatic diaphragmatic rupture in our institution over a ten-year period in the local setting of a tertiary hospital in Ghana. Material and methods: A retrospective review of the medical records of patients who had undergone surgery for traumatic diaphragmatic rupture. Results: A total of 35 cases of diaphragmatic rupture were seen from thoracoabdominal injuries. There were 29 (82.86%) males. The mean age was 36.25 ±12.98 years with a range of 16–65 years. There were 3 cases of right diaphragmatic rupture and 32 cases of left diaphragmatic rupture. Penetrating chest injury caused 18 (51%) of the ruptures. The leading cause of injury was road traffic accident, which constituted 48.57%, closely followed by stab (25.71%), gunshot injuries (14.29%) and impalement injury (11.48%). Seventeen (49%) patients had their diaphragmatic ruptures repaired via laparotomy and the remaining 18 (51%) via thoracotomy. The commonest herniated organ was the stomach. One patient died in theatre from cardiac arrest after failed intubation. Conclusions: Surgery is the treatment of choice in traumatic diaphragmatic rupture and it is repaired via laparotomy or thoracotomy based on the presence or absence of concomitant abdominal injury and the presence or absence of a cardiothoracic surgeon.

Large-scale efforts to identify breast cancer (BC) risk alleles have historically taken place among women of European ancestry. Recently, there are new efforts to verify if these alleles increase risk in African American (AA) women as well. We investigated the effect of previously reported AA breast cancer and triple-negative breast cancer (TNBC) risk alleles in our African-enriched International Center for the Study of Breast Cancer Subtypes (ICSBCS) cohort. Using case–control, case-series and race-nested approaches, we report that the Duffy-null allele (rs2814778) is associated with TNBC risk (OR = 3.814, p = 0.001), specifically among AA individuals, after adjusting for self-indicated race and west African ancestry (OR = 3.368, p = 0.007). We have also validated the protective effect of the minor allele of the ANKLE1 missense variant rs2363956 among AA for TNBC (OR = 0.420, p = 0.005). Our results suggest that an ancestry-specific Duffy-null allele and differential prevalence of a polymorphic gene variant of ANKLE1 may play a role in TNBC breast cancer outcomes. These findings present opportunities for therapeutic potential and future studies to address race-specific differences in TNBC risk and disease outcome. [ABSTRACT FROM AUTHOR]

Background: About 85% of breast cancer patients attending Komfo Anokye Teaching Hospital (KATH), Ghana, present with stage III/IV disease. In spite of great investments into the early diagnosis and management of breast cancer, late presentation persists and poses a barrier to realising the possible benefits of the gains made in breast cancer management. This study assessed the symptom appraisal and medical health seeking behaviour of women with either locally advanced or metastatic breast cancer attending breast clinic at KATH.Method: In-depth interviews of women presenting with clinical stage III/IV breast cancer were conducted to explore the women's care seeking pathways after symptom identification until arrival at KATH from May 2015 to March 2016. Thematic data analysis was conducted using the Andersen behavioural model for health service use.Results: Fifteen women aged 24-79 years were interviewed. The time from symptom identification to reporting to KATH was 4-24 months. The initial symptom was a breast lump or breast swelling which all the women identified themselves. These were initially appraised as not serious because most importantly, they did not interfere with their daily function. Symptom progression such as prevented them from undertaking their usual economic, social and family function triggered seeking care from health facilities. The availability of money to pay for care and diagnostic investigations influenced the time taken to navigate the referral pathway. While the women initially deferred healthcare for reasons related to their ability to perform economic, family and social roles, ultimately, aggressively pursuing healthcare was also for the same economic, family and social reasons or goals.Conclusion: Deciding to seek care and pursue treatment for breast cancer symptoms may be much more complicated than it appears. Economic, family and social function significantly drive the health seeking process both at the personal and health facility phases of health seeking. Breast cancer education messages must be adapted to incorporate these functional goals and their influence on symptom appraisal and decision making to seek help and not just focus on the breast symptom as an isolated entity.

Background: Diabetes-related lower limb amputations (LLA) are associated with significant morbidity and mortality. Although the incidence has decreased over the past two decades in most High-Income Countries, the situation in Low-Middle Income Countries (LMIC), especially those in sub-Saharan Africa (SSA) is not clear. We have determined the incidence and determinants of diabetes-related LLA in Ghana. Methods: This was a tertiary-care-based retrospective cohort study involving patients enrolled in the diabetes clinic of Komfo Anokye Teaching Hospital, Ghana from 1st January 2010 to 31st December 2015 after a median follow-up of 4.2 years. Demographic characteristics and clinical variables at baseline were recorded. The primary outcome was new diabetes-related LLA in each year under study. Cox proportional hazard regression models were used to describe the associations of diabetes-related LLA. Results: The mean age at enrolment for the cohort was 55.9 ± 14.6 years, with a female preponderance (62.1%). The average incidence rate of diabetes-related LLA was 2.4 (95% CI:1.84–5.61) per 1000 follow-up years: increasing from 0.6% (95% CI:0.21–2.21) per 1000 follow up years in 2010 to 10.9% (95% CI:6.22–12.44) per 1000 follow-up years in 2015. Diabetes-related LLA was associated with increased age at enrollment (for every 10 year increase in age: HR: 1.11, CI: 1.06–1.22, p < 0.001), male gender (HR: 3.50, CI:2.88–5.23, p < 0.01), type 2 diabetes (HR 3.21, CI: 2.58–10.6, p < 0.001), high Body Mass Index (HR: 3.2, CI: 2.51–7.25 p < 0.001), poor glycemic control (for a percent increase in HbA1c, HR:1.11, CI:1.05–1.25, p = 0.03), hypertension (HR:1.14, CI:1.12–3.21 p < 0.001), peripheral sensory neuropathy (HR:6.56 CI:6.21–8.52 p < 0.001) and peripheral vascular disease (HR: 7.73 CI: 4.39–9.53, p < 0.001). Conclusion: The study confirms a high incidence of diabetes related-LLA in Ghana. Interventions aimed at addressing systemic and patient-level barriers to good vascular risk factor control and proper foot care for diabetics should be introduced in LMICs to stem the tide of the increasing incidence of LLA.

Background. Thyroid dysfunction is known to exaggerate the coronary heart disease (CHD) risk associated with type 2 diabetes mellitus (T2DM) among whites. The effect is yet to be studied among African populations. Methods. This is a cross-sectional study involving 780 T2DM patients enrolled in a diabetes clinic in Kumasi, Ghana. CHD risk was estimated using the Framingham and UKPDS risk scores. Risks were categorised as low (<10%), intermediate (10–19%), and high (≥20%). Associations between metabolic risk factors, thyroid dysfunction, and CHD risk were measured using Spearman’s partial correlation analysis while controlling for age and gender. Differences were considered statistically significant at p<0.05. Results. 780 T2DM patients (57.7% females), mean ± SD age of 57.4 ± 9.4 was analysed. The median (IQR) 10-year CHD score estimated using the Framingham and UKPDS risk engines for males and females was 12 (8–20), 9.4 (5.7–13.4), p<0.0001 and 3 (1–6), 5.8 (3.4–9.6), p<0.0001, respectively. Positive correlation was found between CHD risk and HbA1c, total cholesterol, low-density lipoprotein cholesterol, systolic blood pressure, and thyroid stimulating hormone. Conclusion. The presence of thyroid dysfunction significantly increased the CHD risk associated with T2DM patients in Ghana. [ABSTRACT FROM AUTHOR]

Background. Although an increasing burden of endocrine disorders is recorded worldwide, the greatest increase is occurring in developing countries. However, the spectrum of these disorders is not well described in most developing countries. Objective. The objective of this study was to profile the frequency of endocrine disorders and their basic demographic characteristics in an endocrine outpatient clinic in Kumasi, central Ghana. Methods. A retrospective review was conducted on endocrine disorders seen over a five-year period between January 2011 and December 2015 at the outpatient endocrine clinic of Komfo Anokye Teaching Hospital. All medical records of patients seen at the endocrine clinic were reviewed by endocrinologists and all endocrinological diagnoses were classified according to ICD-10. Results. 3070 adults enrolled for care in the endocrine outpatient service between 2011 and 2015. This comprised 2056 females and 1014 males (female : male ratio of 2.0 : 1.0) with an overall median age of 54 (IQR, 41–64) years. The commonest primary endocrine disorders seen were diabetes, thyroid, and adrenal disorders at frequencies of 79.1%, 13.1%, and 2.2%, respectively. Conclusions. Type 2 diabetes and thyroid disorders represent by far the two commonest disorders seen at the endocrine clinic. The increased frequency and wide spectrum of endocrine disorders suggest the need for well-trained endocrinologists to improve the health of the population. [ABSTRACT FROM AUTHOR]

Background Graves disease (GD) has increased in prevalence over the past decade in Africa. Despite this, the condition is not well described, especially in sub-Saharan Africa. Objective We have described the clinical characteristics and associated factors of GD in a cohort of patients attending a resource-limited setting tertiary hospital. Methods Patients were examined thoroughly and systematically tested for the degree of clinical and biochemical thyroid status. Thyroid volume, characteristics, and blood flow were assessed at presentation using ultrasonography. Factors associated with an inability to achieve clinical and biochemical thyroid remission were evaluated using multiple logistic regression analysis. Results Overall, 182 patients were studied, 152 (83.5%) were women with a female:male ratio of 5.1:1.0. The mean age at presentation was 39.9 ± 14.7 years with women significantly older than men. Thyroid-associated orbitopathy (TAO) was observed in 56% of the participants and pretibial myxoedema in 6%. About 84% of the participants were hyperthyroid at presentation, 9% were euthyroid, 4% were hypothyroid, and 3% had subclinical hyperthyroidism. Inability to achieve biochemical and clinical remission at 24 months was associated with increased thyroid volume (odds ratio [OR]: 2.35, 95% confidence interval [CI]: 1.85-2.52, P < .001), presence of TAO (OR: 2.15, 95% CI: 2.12-2.33, P < .001), increased FT3/FT4 ratio (OR: 1.33, 95% CI: 1.24-2.56, P = .004), and missed clinic appointment (OR: 5.2, 95% CI: 4.55-7.89, P < .001). Conclusions Graves disease among Ghanaians is associated with significant signs at presentation. Inability to achieve remission within the first 24 months is associated with increased thyroid volume, TAO, an increased FT3/FT4 ratio, as well as missed clinic appointment. [ABSTRACT FROM AUTHOR]
